The technical field

The present invention relates to a system of two-way wireless communication, and more particularly to a two-way wireless communication system, providing the possibility of direct communication between terminals and indirect communication between terminals via another terminal.

Prior art

In a conventional wireless communication system, in which a user using the wireless terminal device can communicate with another user, or you may access the service provider, such as provider e-mail or the Internet, the connection is established via a stationary base station. For example, in a cellular telephone system, if the first user is advised to communicate with the second user, the first user dials on his cell phone the telephone number identifying the device of the second user, then his cell phone sends a message to the nearest base station (first base station), where currently registered phone of the first user requesting the establishment of a call to a second user device. The first base station then forwards the call from the target device of the first user to the second user device. If the second device uses the user is another cell phone or other wireless device, the first base station forwards the call to the second base station, where the currently registered device of the second user. If the second user has been registered in the same cell communication, the first user, the first base station can function as a router and establish a call between the first and second users. However, such routing of the call through the base station is required regardless of the relative locations of the first and second users. Even if the first and second users removed for just one quarter, and the nearest base station is at a distance of ten miles, still the call will be routed through the base station, before it reaches the user.

Another conventional communication system is a system search call (paging system). In a unidirectional system search call, the caller typically enters an identification number specific to the pager via phone or web pages on the Internet, either directly or through a service center provider, and enters the number or the message that should be sent to the pager. The call is received by the paging system provider that identifies the pager that should be sent to the call, the message, which should be transferred. The ISP system then activates some or all of their paging base stations and transmits a message to a pager. However, the person receiving the message on the pager, still need another communication system, such as a telephone, to send a response message. To overcome this problem was proposed bidirectional paging system, the pager itself initiates a message and send it to another pager, as described in U.S. patent 5335246.

However, the above systems based on infrastructure, such as base stations and phone lines, which are fixed in position and provided by service providers and do not allow for direct communication between terminals. The target device used in the system, such as a cellular phone or paging system can transmit and receive signals, but not able to function as routers. If within the area of location of the users did not have the base station, the users could not communicate with each other, even if they were at a small distance from one another. Another disadvantage associated with the above systems is the lack of information about the relative and/or absolute location of the parties to the call or the end devices. Usually the first side, which is the initiator of the call or sends a search call, does not know the location of the other party.

The possibility of direct communication between portable devices two-way radio, such as Voki-currents" (portable radio) is also limited in that none of the information location is not available, and the communication range is limited by the range of action of such a portable radio. It does not provide benefits derived from the availability of appropriate infrastructure.

Accordingly, it would be desirable to be able to provide the infrastructure that enables direct communication between endpoints without requiring a stationary base station. Such infrastructure would be capable of providing the user's location or the target device, and use the target device as a router based on its location relative to another target device, so that such a router facilitated communication between terminal devices that are removed at a distance beyond the range of direct communication. The router must also be able to establish communication between the terminal and another point of access to services, providing services such as e-mail is or the Internet, which may be outside the range of direct connection.

Disclosure of invention

The present invention provides a system and method for wireless communication system that can establish a direct connection between the terminal and an indirect connection between the terminals through the other terminal. The present invention can be implemented as an independent system or as a complement to existing systems, such as cellular telephone system and paging system.

Block diagram of wireless communication system corresponding to the first embodiment of the invention, represented by f is, 1. Wireless communication system (100) includes a first (102), second (104) and the third (106) of the portable communication device operating synchronized manner. Each portable communication device includes a transceiver for transmission in a particular frequency band, which is compatible for each of them and is used both for transmission and for reception of signals. The first portable communication device (102) has an opportunity to establish direct connection with the second portable communication device (104), and may also establish indirect communication with the second portable device (104), which is outside the range of direct communications, by configuring the third portable communication device (106) as a router to extend the range of communication. To establish a direct connection with the second portable communication device (104), the first portable communication device (102) transmits (108) the first message to the second portable communication device (104). If the second portable communication device (104) successfully receives this first message, the connection, and the second portable communication device (104) transmits (110) ACK to the first portable communication device (102). However, if the second portable communication device (104) is not successfully takes the first message, it does not send podtverjdeniyem. The first portable communication device (102) then detects the third portable communication device (106), passes (112) the second message to the third portable communication device (106) and issues a command to the third portable communication device (106) to transmit (114) the second message to the second portable communication device (104). If the second portable communication device (104) successfully receives the second message, the connection is established, and the second portable communication device (104) transmits an acknowledgement (116) to the third portable communication device (106) and issues a command to the third portable communication device (106) to transmit (118) ACK to the first portable communication device (102).

However, if the third portable communication device (106) does not accept acknowledgement (116) from the second portable communication device (104), the third portable communication device (106) can detect the fourth portable communication device (202), having a transceiver for communication at a particular frequency band that is compatible with the first, second and third portable communication devices (102, 104, and 106), as shown in Fig. 2. The third portable communication device (106), functioning as the first router transmits (204) the second message on the fourth portable communication device (202), functioning as a second marscruiser the R, and issues a command of the fourth portable communication device (202) to pass (206) of the second message to the second portable communication device (104). If the second portable communication device (104) successfully receives the second message, the connection, and the second portable communication device (104) transmits an acknowledgement (208) on the fourth portable communication device (202) with a command of the fourth portable communication device (202) to broadcast (210) ACK third portable communication device (106) with a team of third portable communication device (106) to relay the ACK to the first portable communication device (102). If the second portable communication device (202) may not transmit the ACK, the process, subject to the discovery router another portable communication device, and issuing a command to relay the message that is repeated as long as the second portable communication device (202) does not transmit the ACK or repeats until then, until it reaches the specified number of marshrutizatorov to avoid endless relay.

As shown in Fig. 3, when functioning as a router, the third portable communication device (106) can still install a separate direct connection between the portable us what devices (302, 304) with the fourth portable communication device (306)having a transceiver for communication at a particular frequency band, which is compatible with the first, second and third portable communication devices (102, 104, 106, respectively). Through the use of multiple modulation schemes, such as modulation spread spectrum with abrupt frequency change (FHSS), the third portable communication device (106) can function as a router (112, 114 and 116, 118) for the first and second communication devices (102 and 104, respectively) using a single segment (interval) while maintaining the possibility of establishing a separate direct connection (302, 304) with the fourth portable communication device (306) using a different time interval.

Each of the preferred embodiments of the wireless communication system in accordance with the present invention, described above, is an independent system without a fixed base station or a wired infrastructure. However, another aspect of a wireless communication system corresponding to the present invention is an improvement of the existing infrastructure. In Fig. 4 shows a fourth preferred variant implementation of the wireless communication system (400) in accordance with the present invention, complementary to existing the existing infrastructure. Each of the many portable communication devices in the wireless communication system (400) operates as a portable unit of the existing infrastructure. First, second and third portable communication device (402, 404 and 406, respectively) from a variety of portable communication devices shown in Fig. 4. The base station (408), which is a component of the existing infrastructure, such as cellular telephone system or the search system call is connected with a wired communication system, such as based on land lines telephone system (410). The base station (408) may communicate with any of a variety of portable communication devices that are within range (412) communication base station (408). As a function of the existing infrastructure, the caller by using the telephone system (410), may establish a connection (414, 416) with the third portable communication device (406) via the base station (408). The improvement of the existing infrastructure is to enable the caller using the telephone system (410), connect (414, 416) with the third portable communication device (406) via the base station (408), while the third portable communication device (406) functions as a router (418, 420 and 422, 424) for the first and second portable devices tie is (402 and 404, respectively). Communications (416) from the base station (408) to the third portable communication device (406) is performed using the communication Protocol used in the existing infrastructure. Depending on the infrastructure, such as infrastructure pager or cellular telephone system, which is deployed wireless communication system corresponding to the present invention, the Protocol used in the existing infrastructure, can be a Protocol pager mode multiple access with time division multiplexing (TDMA), multiple access, code division multiple access (CDMA) and Protocol global system for mobile communications (GSM). Each portable communication device uses multi-modulation scheme, for example, modulation spread spectrum using frequency-hopping (FHSS).

Fig. 5 illustrates the fifth preferred implementation of the wireless communication system (500)in accordance with the present invention, further perfects the described fourth preferred variant implementation, by providing a transceiver that is compatible with transceivers portable communication devices, base stations (502). The base station (502) connected to a service provider (504), such as Internet service provider, and which allows the exchange of information with the service provider (504) via the existing network (506), such as the telephone network. The first portable communication device (508) from a variety of portable communication devices in the wireless communication system (500) has connectivity to a service provider (504) via the base station 502. In addition, because each of the many portable communication devices has the capability of functioning as a router, as described above, the second portable communication device (510) also has access to the service provider (504) by establishing a connection (512, 514) with the first portable communication device (508), and the use of the first portable communication device (508) as a router that establishes a connection (516, 518) to the base station (502). When functioning as a router first portable communication device (508) may establish separate communication (520, 522) with the third portable communication device (524).

Block diagram of wireless communication system (600)in accordance with the sixth preferred embodiment of the present invention shown in Fig. 6. Wireless communication system (600) includes a location system (602), such as global positioning (GPS), and a variety of portable communication devices located within a certain area. Each of this set by the consultative communication device is a transceiver for communication at a particular frequency band, which are compatible with each other, such as a transceiver mode FHSS, and receiver positioning, such as GPS receiver. Geographic area where deployed wireless communication system (600), divided into many cells, and each cell is defined by its boundary line, and one cell is defined as the reference cell, the coordinates of which are used by all other cells as a reference (Fig. 6 shows four cells: cell 604 bordering 605, cell 606, bordering 607, cell 608, bordering 609, and the cell 610, with a boundary 611). Each cell has specific coordinates that define its geographical area and its location relative to the reference cell. In Fig. 6 cell 604 is shown as a reference cell with the cell coordinates With(0,0). Cell 606 having coordinates of cell(1,1)is relative to the reference cell one cell to the next in the positive direction of the x-axis and one unit further in the positive direction of the y axis. Similarly, the cell 608 has the coordinates of the cell C(0,-1) and cell 610 has the coordinates of the cell C(1, -1), and each of them describe the location relative to the reference cell 604. Each cell has a predetermined set of communication parameters assigned to it for use in the cell of the portable communication device. PE is the first, second, third and fourth portable communication device (612, 614, 616 and 618, respectively) from a variety of portable communication devices shown in Fig. 6 in the first cell (604). Wireless communication system (600) may be part of an existing wireless network (628), such as a paging system or a cellular telephone system, each of the multiple portable communication devices can also operate in an existing wireless network (628).

In Fig. 7 shows for example the division of each cell into three areas, and each area has a specific set of parameters that should be used in portable communication devices, further defining their function in this region. Each portable communication device periodically update their information location through a GPS system, because it can move from one cell to another, or from one area to another within the same cell, and the function of the portable communication device in the wireless communication system (600) is determined on the basis of its location. The GPS system can help establish synchronization for portable communication devices to ensure proper operation in the wireless communication system (600).

Central region (702) is defined by the first boundary line (704), and then the exploring communication devices, within the Central region (one shown 616)is classified as a Central boundary units (CBU). The CBU units provide retransmission of messages in the cell, if a direct connection between two portable communication devices within the same cell is not installed. The CBU units can also generate and receive their own messages, as described above portable communication devices in the system. When the portable communication device is in the Central region (702) and receives GPS information, the portable communication device identifies itself as a CBU unit and based on their current GPS information is registered in the wireless communication system (600) as a CBU unit, and periodically transmits the data to its location, identity, and length of stay in as a CBU unit. In order to avoid loss of CBU units in the cell, the first portable communication device, functioning as a unit CBU, should be replaced by the second portable communication device that has registered itself as a CBU unit, before the first portable communication device will stop functioning as a unit CBU, if only the first portable unit will not leave Central border. For example, according to Fig. 7, if the first portable communication device (616) leaves the Central region is t (702), it may stop functioning as a CBU unit. However, the first portable communication device is unable to stop functioning as a unit CBU due to the length of time during which it functioned as a unit CBU, or due to power requirements, unless the replacement was not registered. If the CBU unit connects to the battery, he identifies himself and is registered in the wireless communication system (600) as a reliable static Central boundary of the block (RSCBU) and can function as a CBU unit for an extended period of time.

The second area (706) is defined by the first boundary line (704) and the second boundary line (708), and portable communication devices that are within the second region (one shown 618)is classified as a regular portable units (RPU). Portable communication device determines its classification on the basis of your location via GPS. Blocks RPU can generate and receive their own messages as previously described portable communication devices in the system, but unlike CBU units, blocks RPU is not responsible for relaying messages.

The outer region (710) the second boundary line (708) and the boundary line (605) cells, and portable communication devices, which nahodatsa is in the outer region (shown two 612 and 614), classified as external boundary units (OBU). Cell (604) further subdivided into six sectors S1, S2, S3, S4, S5 and S6(712, 714, 716, 718, 720 and 722, respectively), a portable communication device in the outer region determines its classification and its sector based on its location via GPS. Each sector is close to another sector adjacent cells (shown sector 716 cell 604 and the sector 724 cell 610). Blocks OBU can generate and receive their own messages as previously described portable communication devices in the system. Unit OBU provides retransmission of messages in the adjacent cell. When the portable communication device is in the outer region (710) and receives GPS information, the portable communication device identifies itself as a unit OBU based on your current GPS data is registered in the wireless communication system (600) as the unit OBU and periodically transmits the data to its location and identification as a unit OBU.

In Fig. 8 shows the block diagram (800) procedure by which the first portable communication device (612) may be registered in the wireless communication system (600), respectively, and to identify its function.

At step 802, the first portable communication device (612) turns on and then at step 804, it receives information about the time and frequency synchro is Itachi from the global positioning system (602). At step 806, the first portable communication device (612) also identifies the cell in which it is currently based on the information received from the global positioning system (602). At step 808, the first portable communication device (612) additionally receives the communication parameters, which are defined and specific for the cell in which it is at the moment. At step 810, the first portable communication device (612) determines whether it should function as a unit RPU, based on what cell it is in the moment. If the first portable communication device (612) decides to function as a unit RPU, it collects information from CBU units and OBU, which are located in the same cell, and that it itself (812), as shown in step 812, and then proceeds to normal operation, as shown in step 814.

However, if the first portable communication device (612) decides not to function as a unit RPU, then it's on step 816 determines whether it should function as a unit CBU, based on which cell it is. If the first portable communication device (612) decides to function as a unit CBU, it broadcasts and identifies the CE which I as a CBU unit at step 818 and collects information from blocks OBU, located in the same cell, as it is itself, at step 820. At step 822, the first portable communication device (612) periodically transmits information based on your location and collects information from blocks OBU and then goes to normal operation at step 814.

However, if the first portable communication device (612) decides not to function as a unit CBU, it functions as a unit OBU, and at step 824, it broadcasts and identifies itself as a unit OBU. The first portable communication device (612), and then collects information from CBU units located in the same cell, as it is itself, and from CBU units, located in the adjacent cells, at step 826. The first portable communication device (612) periodically transmits information based on your location and collects information from blocks OBU at step 828 and then goes to normal operation at step 814.

Fig. 9 and 10 illustrate flowcharts of procedures (900 and 1000), describing how the first portable communication device (612) in the first cell (604) tries to establish a connection with the second portable communication device (614) in the same cell (604).

In Fig. 9 shows how this attempt is differentiated based on the location information of the second portative the communication device (614) in the same cell (604), and illustrated in the corresponding way, when the location of the second portable communication device (614) in the same cell (604) is known. At step 902, when the first portable communication device (612) turns on, the first portable communication device (612) passes the registration process at step 904, as described with reference to Fig. 8. When the user of the first portable communication device (612) enters a message and identifies the second portable communication device (614) as the recipient, the first portable communication device (612) at step 906 determines whether the known location of the second portable communication device (614) finding out first cell (604). If the first portable communication device (612) defines it, it starts at step 908, the process of broadcasting outside the cell. Otherwise, the first portable communication device (612) at step 910 determines whether the location of the second portable communication device (614) known location in the first cell. If the location of the second portable communication device (614) in the first cell (604) is unknown, then the first portable communication device (612) at step 914 transmits the message using the most appropriate route. The most suitable route may be a direct route or previously used Mar is Ruth, ensuring successful communication with the second portable communication device. For example, if the last time the first portable communication device (612) successfully established communication with the second portable communication device (614) using the route through the device 612-616-614, the first portable communication device (612) transmits a message using this route. At step 916, the first portable communication device (612) expects to receive an acknowledgment (ACK) from the second portable communication device within a specified period of time of receipt in order to avoid infinite timeout receiving ASA. The acknowledgment message, the ACK may include, in addition to the confirmation of admission, time of admission, the location of the second portable communication device, route messages and other desirable information. If the first portable communication device (612) receives an acknowledgement (ACK) within a specified time, then at step 918, it indicates that the message was successfully accepted, and resumes its normal operation in step 920. The user of the first portable communication device (612) may initiate the preparation of a new message and repeats the process from step 906. If the first portable communication device (612) does not receive the ACK, the ACK within a specified time and, at step 922, it checks whether the message is transmitted a predetermined number of times (N1). If the number N1 is not exceeded, then the first portable communication device at step 914 re-transmits the message using the more appropriate route. If the number N1 is reached, then the second portable communication device at step 924 qualifies as unattainable, and the first portable communication device (612) resumes its normal operation in step 920. The user can start preparing a new message and repeat the process from step 906.

Fig. 10 illustrates the method when the location of the second portable device (614) in the first cell (604) is unknown, and the first portable communication device (612) at step 912 procedure begins broadcasting to an undefined location. At step 1002, the user of the first portable communication device (612) selects the status messages between the broadcast messages only within the first cell (604) or broadcast transmission to other cells if the second portable device (614) is not available in the first cell (604), and the message is marked appropriately to indicate the user's choice. At step 1004, the first portable communication device (612) sends the message directly sent to the second-the further communication device (614), then at step 1006 is waiting for acknowledgment ASC sent message from the second portable communication device (614) within a specified time. If the first portable communication device (612) receives the message, the ACK within a specified time, then at step 918, it indicates that the message was successfully accepted, and at step 920 resumes normal operation. The user can start preparing a new message and repeat the process from step 906.

If the first portable communication device (612) does not receive the message the ACK within a specified time, then at step 1008 determines whether it operates as a CBU unit. If the first portable communication device (612) determines that it is functioning as a unit CBU, then at step 1010, it checks whether it is sent to the specified number (N2) time. If the number N2 is not exceeded, then at step 1004, the first portable communication device re-transmits the message directly sending it to the second portable communication device (614). If the number N2 is reached, then at step 1012, the first portable communication device (612) checks the status of the message. If the status message indicates that the broadcast is limited to the first cell (604), then the second portable communication device at step 924 qualifies as unattainable, and the first portable device is STW communications at stage 920 resumes its normal operation. The user can start preparing a new message, and the process is repeated from step 906. If the status message indicates that broadcasting should continue in other cells, if the second portable communication device (614) did not become available within the first cell (604), it starts at step 908, the process of broadcasting outside the cell.

If the first portable communication device (612) determines that it is not functioning as a unit CBU, then at step 1014, it searches for the first block CBU, which should be used as a router. If it is determined that none of the CBU unit is not available for use as a router, then at step 1010, the first portable communication device (612) determines whether the sent message a specified number (N2) time. If the number N2 is not exceeded, then at step 1004, the first portable communication device relays the message directly to the second portable communication device (614). If the number N2 is reached, then at step 1012, the first portable communication device (612) checks the status of the message. If the status message indicates that the broadcast is limited to the first cell (604), then the second portable communication device at step 924 qualifies as unattainable, and the first portable communication device at step 920 in which updates its normal operation. The user can start preparing a new message, and the process is repeated from step 906. If the status message indicates that broadcasting should continue in other cells, if the second portable communication device (614) unattainable within the first cell (604), it starts at step 908, the process of broadcasting outside the cell.

If the first block CBU (616) available for use as a router, then the first portable communication device (612) sends the message to the first block CBU (616) in step 1016, and issues a command to the first block CBU (615) to broadcast the message to the second portable communication device (614) at step 1018. Then at step 1020, the first portable communication device (612) expects to receive an acknowledgment (ACK) from the second portable communication device (614) message is received through the first block CBU (615) within a specified time. If the first portable communication device (612) receives an acknowledgement (ACK) within a specified time, then at step 918, it indicates that the message was successfully accepted, and resumes its normal operation in step 920. The user can start preparing a new message and repeats the process from step 906. If the first portable communication device (612) does not receive the ACK, the ACK within a specified time, at a stage one checks whether the message is transmitted a predetermined number of times (N2). If the number N2 is not exceeded, then the first portable communication device at step 1004 re-transmits the message directly sending it to the second portable device (614). If the number N2 is reached, then the first portable communication device (612) checks the status of the message at step 1012. If the status message indicates that the broadcast is limited to the first cell (604), then the second portable communication device at step 924 qualifies as unattainable, and the first portable communication device resumes its normal operation in step 920. The user can start preparing a new message and repeat the process from step 906. If the status message indicates that broadcasting should continue in other cells, if the second portable communication device (614) unattainable within the first cell (604), it starts at step 908, the process of broadcasting outside the cell.

Fig. 11 illustrates a block diagram representing a wireless communications system (1100)according to the seventh preferred variant of the invention, when installing broadcast outside the cell at step 908. The first portable communication device (1102) from a variety of portable communication devices, on odawise in the first cell (1104), trying to establish a connection with the second portable communication device (1106) from a variety of portable communication devices located in the second cell (1108). As described above, the wireless communications system (1100) includes a location system (1110), such as global positioning (GPS), and a variety of portable communication devices located in a certain area. Each of this set of portable communication devices has a transceiver for communication at a particular frequency band, which are compatible with each other, such as a transceiver mode FHSS and receiver positioning, such as GPS receiver. Geographic area where deployed wireless communication system (1100), divided into many cells (Fig. 11 shows two cells: cell 1104 and the cell 1108). Each cell has a Central region (1112, 1114) around the center of the second region (1116, 1118), surrounding the Central region (1112, 1114), and an outer region surrounding the second region, within the boundaries of the (1120, 1122), and the outer region is divided into six sectors, each of which is adjacent to another cell. Each portable communication device is classified as a Central limit unit (CBU), reliable static Central limit unit (RSCBU), regular portable unit (RPU), or the outer Gran is CNY unit (OBU) depending on its current location and may be recorded as such in the existing wireless network.

In Fig. 12 shows the block diagram is shown for receiving procedures broadcast outside the cell at step 908. As soon as the first portable communication device (1102) determines that it is desirable to broadcast the outside of the cell, it first determines at step 1202, it is known whether the location of the second portable communication device (1106). If known, then at step 1204, the first portable communication device (1102) sends the message using the most appropriate route, which can be a direct route or a previously used route that ensures successful communication with the second portable communication device (1106). At step 1206, the first portable communication device (1102) expects to receive an acknowledgment (ACK) from the second portable communication device (1106) within a specified period of time of receipt in order to avoid infinite timeout receiving ASA. The acknowledgment message, the ACK may include, in addition to the confirmation of admission, time of admission, the location of the second portable communication device, route messages and other desirable information. If the first portable communication device (1102) receives the ACK, the ACK within a specified time, then at step 918, it indicates that the message was successfully accepted, the resumes its normal operation in step 920. The user of the first portable communication device (1102) may initiate the preparation of a new message and repeats the process from step 906. If the first portable communication device (1102) does not receive the ACK, the ACK within a specified time, then at step 1208, it checks whether the message is transmitted a predetermined number of times (N3). If the number N3 is not exceeded, then the first portable communication device (1102) at step 1204 re-transmits the message using the more appropriate route. If the number N3 is reached, then the second portable communication device (1106) at step 924 qualifies as unattainable, and the first portable communication device (1102) resumes its normal operation in step 920. The user can start preparing a new message and repeat the process from step 906. Alternatively, the user can select a treatment option when the location of the second portable communication device (1106) is unknown.

If the location of the second portable device (1106) is unknown, then the first portable communication device (1102) at step 1210 checks the length of the message in relation to a given length. If the message length is less than the specified length, or the message is less than the specified number of characters, then in step 1212, the first portable communication device transmits a message via shared the broadcast. In Fig. 13 shows a flowchart of procedure of the General broadcast, running on stage 1212.

When the first portable communication device (1102) at step 1212 starts the procedure of General broadcast, it first determines at step 1302, whether it operates as a CBU unit. If the first portable communication device (1102) defines it, it is at the stage 1304 searches for available blocks OBU.

If the first portable communication device (1102) determines at step 1302, it is not functioning as a unit CBU, then at step 1306, it searches for available block CBU. If it does not find any available block CBU, then at step 1304, the first portable communication device (1102) searches for available blocks OBU. If the first portable communication device (1102) finds a block CBU, then at step 1308, it is synchronized with this unit CBU. The first portable communication device (1102) at step 1310 transmits a message to the unit CBU and gives him a command to search for available units OBU. Then the CBU unit searches for available blocks OBU at step 1304.

If there are no blocks available OBU, the second portable communication device (1106) at step 924 qualifies as unattainable, and the first portable communication device (1102) resumes its normal operation in step 920.

If available, at least, Odie the unit OBU, at step 1312 determines the coverage sector. If the available unit OBU and it is found in each sector, then in step 1314 message is sent to all the detected blocks OBU with command blocks for OBU to broadcast the message outside the cell with a predetermined non-repeating transmission schemes. If only some, but not all sectors are covered detected blocks OBU, then at step 1316, the message is forwarded to all the detected blocks OBU with command blocks for OBU to broadcast the message outside of the cell. The command can optionally request blocks OBU modify the preset transmission schemes outside the cell to provide coverage of certain sectors that do not have available blocks OBU. At step 1318, the first portable communication device (1102) is notified that the message has been sent outside the borders of the cell.

Successful delivery of the message to all the detected blocks OBU is determined by obtaining at step 1320 acknowledgment (ACK) from the blocks OBU. If the acknowledgment ASC from all detected blocks OBU received blocks OBU transmits the message to neighboring blocks CBU, and the message is transmitted in step 1322, using a suitable transmission schemes. Then the first portable communication device (1106) at step 1324 is waiting for confirmation of receiving the ACK from the second portable communication device (1106). Ecopelle portable communication device (1102) receives the ACK, the ACK within a specified time, at step 918, it indicates that the message was successfully accepted, and resumes its normal operation in step 920. If the first portable communication device (1102) does not receive the ACK, the ACK from the second portable communication device (1106) within the specified time, then the second portable communication device (1106) at step 924 qualifies as unattainable, and the first portable communication device (1102) resumes its normal operation in step 920. Alternatively, the first portable communication device may detect a different set of blocks OBU or can find another block CBU and give him the command to find another set of blocks OBU and to repeat the procedure a General broadcast.

If only a subset of the detected blocks OBU responds by sending an acknowledgment ASC, the first portable communication device (1102) determines whether the message was transmitted specified number (N4) time. If the number N4 is not exceeded, then the first portable communication device (1102) may overlap the common broadcast. If the number N4 is reached, the message is broadcast to only those blocks OBU that on stage 1322 sent an acknowledgment message to the ASA. Then the first portable communication device (1102) waits at step 1324 confirmation of reception of the ACK from the second portable communication device (1106). E. what if the first portable communication device (1102) receives the ACK, the ACK within a specified time, at step 918, it indicates that the message was successfully accepted, and resumes its normal operation in step 920. If the first portable communication device (1102) does not receive the ACK, the ACK from the second portable communication device (1106) within the specified time, then the second portable communication device (1106) at step 924 qualifies as unattainable, and the first portable communication device (1102) resumes its normal operation in step 920. Alternatively, the first portable communication device may detect a different set of blocks OBU or can find another block CBU and give him the command to find another set of blocks OBU and to repeat the procedure a General broadcast.

If the message length exceeds the specified length, then the first portable communication device (1102) at step 1214 generates a message location specifically to determine the location of the second portable communication device (1106). Message location is sent using the same method that the General broadcast at step 1212, to determine the location of the second portable communication device (1106) at step 1216. Instead of receiving acknowledgment ASC for the successful delivery of a message if the message location reaches the second-the nogo communication device (1106), the first portable communication device (1102) receives a successful route, which passed the message for delivery to the second portable communication device (1106), which is the first portable communication device (1102) will use to send the message. If the message location has not reached the second portable communication device (1106), then the second portable communication device (1106) at step 924 qualifies as unattainable, and the first portable communication device (1102) resumes its normal operation in step 920.

If the message location has reached the second portable communication device (1106), then at step 1204, the first portable communication device (1102) sends the message using the most appropriate route based on additional knowledge about the location of the second portable communication device (1106). At step 1206, the first portable communication device (1102) expects to receive confirmation of receiving the ACK from the second portable communication device (1106) within a specified period of time of receipt, in order to avoid infinite timeout receiving ASA. If the first portable communication device (1102) receives the ACK, the ACK within a specified time, then at step 918, it indicates that the message was successfully accepted, and resumes its normal operation in step 920. E. what if the first portable communication device (1102) does not receive the ACK, the ACK within a specified time, at step 1208, it checks whether the message is transmitted a predetermined number of times (N3). If the number N3 is not exceeded, then the first portable communication device (1102) at step 1204 re-transmits the message using the more appropriate route. If the number N3 is reached, then the second portable communication device at step 924 qualifies as unattainable, and the first portable communication device resumes its normal operation in step 920.

Fig. 14 illustrates a relationship diagram between a portable communication device according to Fig. 11 mode total broadcast outside of the cell.

The first portable communication device (1102) determines that it does not function as a CBU unit at step 1302, searches for available units CBU at step 1306, and detects the block CBU (1124) from a variety of portable communication devices located in the Central region (1112) of the first cell (1104), for use as a router at step 1308. At step 1310, the first portable communication device (1102) passes to block CBU (1124) message and the team search for available blocks OBU located in the first outer region (1120) of the first cell (1104), as shown by the arrow 1402. As shown in Fig. 14, available and found the unit OBU in each sector, as it takes place at step 1312, and the unit CBU (1124) sends the message to all detecting the defined blocks OBU (1126, 1128, 1130, 1138, 1140, 1142) with command blocks for OBU to relay the message outside the cell with a predetermined non-repeating transmission schemes outside the cell, as it takes place at step 1314. Blocks OBU is responsible, as determined in step 1320, the acknowledgement ASC sent to the unit CBU (1124). Transfer between the block CBU (1124) and blocks OBU arrows 1404, 1406, 1408, 1410, 1412 and 1414. Send the message blocks OBU outside of the cell is shown by arrows 1416, 1418, 1420, 1422, 1424 and 1426. The first portable communication device (1102) is notified that the message has been sent outside the cell, and waits for acknowledgement of reception of the ACK from the second portable communication device (1106), as determined in step 1324.

Detection blocks OBU can work together to run the unit CBU (1124) and the first portable communication device (1102), as shown in Fig. 15.

The first portable communication device (1102) first detects the block CBU (1124) from a variety of portable communication devices located in the Central region (1112) of the first cell (1104), for use as a router and then passes to block CBU (1124) the search command in the first set up three blocks OBU (1126, 1128, and 1130) from a variety of portable communication devices located in the first outer region (1120) of the first cell (1104). Transfer between the block CBU (1124) and the first portable communication device (1102) shows p is the LCA 1502, and transfer between the block CBU (1124) and the first set of blocks OBU (1126, 1128, and 1130) arrows 1504, 1506 and 1508. Each of the first set of blocks OBU is in a different sector (1132, 1134 and 1136, respectively) of the first outer region (1120) of the first cell (1104).

The first portable communication device (1102) also detects a second set of up to three blocks OBU (1138, 1140 and 1142) from a variety of portable communication devices located in the first outer region (1120) of the first cell (1104). Transfer between the first portable communication device (1102) and the second set of blocks OBU (1138, 1140 and 1142) arrows 1510, 1512 and 1514. Each of the second set of blocks OBU is in the sector (1132, 1134 and 1136, respectively) of the first outer region (1120) of the first cell (1104), which differ one from each other and from the sectors of the first set (1144, 1146 and 1148, respectively).

The first portable communication device (1102) then transmits a message directed to the second portable communication device (1106), together with a request to broadcast outside the cell to the unit CBU (1124) and the second set of up to three blocks OBU(1138, 1140, 1142).

Upon receipt of a message block CBU (1124) receives a command to relay the first message along with a request to broadcast outside the cell to the first set of blocks OBU (1126, 1128, and 1130). The first and second sets of blocks OBU(1126, 1128, 1130, 1138, 1140, 1142) after the of Riem message along with a request to broadcast outside the cell receives a command to transmit the first message in the cell, adjacent to each of the first and second sets of blocks OBU(1126, 1128, 1130, 1138, 1140, 1142). Send the message blocks OBU arrows 1516, 1518, 1520, 1522, 1524 and 1526.

The first portable communication device (1102) expects to receive confirmation of receiving the ACK from the second portable communication device (1106) within a specified time of receiving the message via one of the first and second sets of blocks OBU(1126, 1128, 1130, 1138, 1140, 1142) and determines been accepted successfully the first message to the second portable communication device. The acknowledgment message, the ACK may include, in addition to the confirmation of admission, time of admission, the location of the second portable communication device, route messages and other desirable information. If the first portable communication device (1102) receives the ACK, the ACK within a specified period of time, it indicates that the message was successfully accepted, and resumes its normal operation. The user of the first portable communication device (1102) may initiate the preparation of a new message and repeats the process. If the first portable communication device (1102) does not receive the ACK, the ACK within a specified time, then the above steps may be repeated a predetermined number of times in order to avoid infinite loops. This cycle process can Petropavlosk another block CBU, different from the previously used block CBU, and other sets of blocks OBU, other than those already used sets of blocks OBU.

For communication between two portable communication devices located in different cells, each unit OBU functions as a portable radio communications device, which is the source of the message, after receiving a request to broadcast outside of the cell. However, to avoid transmitting the same message to any cell more than once, preferably applied, non-scheme transfer messages. Fig. 16 illustrates an example of such a non-repeating transmission schemes (1600). Transfer from CBU unit to unit OBU in the cell shown by the solid arrow, and the transmission unit OBU to the unit CBU in the neighboring cell is shown by a dashed arrow. Portable radio communications device, which is the source of the message, is located in the reference cell, marked With(0,0).

In Fig. 17 shows another example of transmission schemes based on the locations of the cells. If the message originates from the first portable communication device (1702) in the reference cell (1704), the message is transmitted on the first route (1706), reaching all the cells. If the message originates from a second portable communication device (1708) from cell (1710), which is not the reference cell (1704), what about the message is transmitted on the second route (1712), which is the same route and in the same direction as the first route, for cells before the cell source (1710), and at a third point (1714), which is the same route but in the opposite direction relative to the first route, to the cells behind the cell source (1710). However, if the cell receiver is known (1718), the message can be transmitted from the cell source (1716) using the most direct route (1720).

As shown in Fig. 18, if the location of the second portable communication device (1802) is known, the first portable communication device (1804), which is the source of the message, there is no need to use a specific non-recurring scheme, as described above. Instead, the first portable communication device (1804) may use a suitable route (1806, shown in solid arrows), which may be more direct than the route (1808 shown in dotted arrows), certain specified non-recurring scheme. However, if the CBU unit or unit OBU is not available in the cell, which would create a more direct route, suitable route may not be referred to the most direct route. An example of a suitable route, not the most direct route (1810 indicated by double arrows), also shown in Fig. 18.

In Fig. 19 is provided to the application example of the present invention. Communication system (1900) in this example contains two zones (1902 and 1904), which are physically separated from each other: the first zone Zone 1 (1902) may cover the Central area of the EPCOT Countries Walt Disney, and the second zone Zone 2 (1904) may cover area of the Magic Kingdom. Each zone contains a local cell in each zone is shown 12 cells) and the relay zone (respectively the first and second repeaters 1906 and 1908 zones). Repeaters zones (1906 and 1908) function as a reliable static Central boundary blocks (RSCBU), but is fixed in position (1906 cell 1908 1910 and in cell 1912) and compared with the conventional portable communication devices have more power to cover the distance between zones, and also have more computing power to meet the requirements of the communications between zones. This example describes how the first user with the first portable communication device (1914), located in the first cell (1916) the first zone (1902), may communicate with the second user with the second portable communication device (1918) in the second cell (1920) the second zone (1904). As described in the registration process shown in Fig. 8, all portable communication devices participating in the communication system (1900), have all the necessary information related to cells and locations.

The first user to identify the duty to regulate and selects the desired recipient of the message which is the second portable communication device (1918) in the Magic Kingdom (1904). Portable communication device used in this system can provide the desired designation of the recipient as part of its menu. Instead of displaying the "Zone 2" it will display "Magic Kingdom" and automatically associate "Magic Kingdom" with the designation of the field system "Zone 2", thereby allowing the user to more easily identify and differentiate the marked area. It may also provide a user-defined identification for portable communication devices, so that user names can be used to identify portable communication devices.

The first user then enters a message in the first portable communication device (1914) and transmits the message to the second portable communication device (1918) by choosing, for example, the command "SEND" "send"). The first portable communication device attaches header information to the message for transmission control message containing: identification zone and source zone of the recipient, a valid zone transfer, portable communication devices and cells; request acknowledgment (ACK); timestamp; the requirement is completed by determining the number of transfer areas (leaps)to avoid infinite the gear. Since the message is sent through various portable devices radio, functioning as CBU units or OBU in different cells, each of these portable devices may attach an additional header information to the message, such as its identification, the route of transmission of messages up to this point, the elapsed time and the number of transfer areas to the current time.

In this example, since the user has selected the Magic Kingdom as the recipient of the message, which is Zone 2 (1904), the message is transmitted via a suitable route that is directed toward the first relay zone (1906), for transmission to the second relay zone (1908) in Zone 2 (1904). If the message recipient is not known, the message should be given a non-recurring transfer scheme, such as described above with reference to Fig. 12. To prevent many portable communication devices in Zone 1 (1902) tried to communicate with another portable communication device outside Zone 1 (1902), such as those in Zone 2 (1904), the direction of the message is completed in Zone 1 (1902), except for messages that have reached the first relay zone (1906). Then the first relay zone (1906) transmits a message to the relays of the other zones in the system. If the header indicates that the message should be sent is I'm only in one zone, for example, the area of the recipient is the same as the area of the source, the relay zone will not send a message to relay.

When the second relay zone (1912) receives a message, it extracts the header information and updates allowed zone transfers on Zone 2 (1904). Only repeaters zone can modify the header of the allowed zone transfers. Then the second relay zone (1912) initiates the transmission of the message tracking given a non-repeating transmission scheme, such as the transmission scheme described above with reference to Fig. 12. If a portable communication device in Zone 2 (1904) accept the message from the first relay zone (1906), they will not send message, as the header information indicates that allowed zone transfers for this message is a Zone 1 (1902), but not Zone 2 (1904).

If the message does not reach the second portable communication device (1918), the message having as allowed zone transfers Zone 2 (1904), completed in Zone 2 (1904) and will not be transferred. If the second portable communication device (1918) receives a message, it transmits the ACK the ACK to the first portable communication device (1914) on the relevant route, which can be opposite to the route used by the message for receipt by the second portable device is in communication (1918).

Fig. 20, 21 and 22 illustrate examples of flow charts describing how a message can be transmitted from the cell, which is the source of the message, using the dynamic transmission schemes based on the coordinates of specific cell relative to the cell which is the source of the message. These stages can be considered as components of step 1212 of Fig. 12 to broadcast a short message, and step 1214 of Fig. 12 to generate the message location, provided all of the information received as described above. In this example, the cell in which the first portable communication device that originated the message, considered as the reference cell messages with cell coordinates With(0,0). Other cells have corresponding coordinates relative to the reference cell of the message, as shown in Fig. 16. Due to the fact that the first portable communication device failed to receive the ACK, the ACK from the second portable communication device after the message is transmitted within the cell(0,0), the first portable communication device starts the General procedure broadcast. This procedure is initiated by a message delivered to the unit OBU in all sectors of the cell(0,0), with the request to send outside of the cell. These blocks OBU transmits the message to the CBU units in neighboring is estorach. For example, blocks OBU in the sector 1, 2, 3, 4, 5, 6 pass the message to the CBU units in adjacent cells transmit with neighboring sectors 4, 5, 6, 1, 2, 3 respectively. Blocks CBU neighboring cells transmit will try to find the second portable communication device in his cell before performing further outside of the cell. If the second device is not detected, it is further outside of the cell.

In accordance with Fig. 20, at step 2004, the coordinates, relative to the reference cell messages to cell transmission, X and Y, are compared with the set of coordinates where X is zero and Y is a positive odd number. If the cell transfer has coordinatesbefore(0, +odd), then at step 2006 unit CBU in this cell sends a message to the unit OBU in S1 cells, and the unit OBU sends a message to the unit CBU in the cell location(0,Y+1). If the coordinates of the cell transmission do not match with this set of coordinates, it uses the following set of coordinates.

At step 2008, the coordinates of the cell transmission relative to the reference cell messages X and Y, are compared with the set of coordinates where X is zero and Y is a negative odd number. If the cell transfer has coordinatesbefore(0, odd), then at step 2010 unit CBU in the cell(0, odd) sends a message to the unit OBU in S4 cell, and the unit OBU sends the communication to the block CBU in the cell location(0,Y-1). If the coordinates of the cell transmission do not match with this set of coordinates, it uses the following set of coordinates.

At step 2012, the coordinates of the cell transfer, relative to cell messages X and Y, are compared with the set of coordinates where X is a negative odd number, and Y is a positive even number or a negative odd number. If the cell transfer has coordinatesbefore(-odd +even or odd), then at step 2014 unit CBU in the cellbefore(-odd +even or odd) sends a message to the unit OBU in S6 cellbefore(-odd +even or odd), and the unit OBU sends a message to the unit CBU in the cell that has the S3 next to S6 cellbefore(-odd +even or odd). If the coordinates of the cell transmission do not match with this set of coordinates, it uses the following set of coordinates.

At step 2016, the coordinates of the cell transfer, relative to cell messages X and Y, are compared with the set of coordinates where X is a positive odd number, and Y is a positive even number or a negative odd number. If the cell transfer has coordinatesbefore(+odd +even or odd), then at step 2018 block CBU in the cellbefore(+odd +even or odd) sends a message to the unit OBU in S2 cells Withbefore (+odd +even or odd), and the unit OBU sends a message to the unit CBU in the cell that has the S5 next to the S2 cellbefore(+odd +even or odd). If the coordinates of the cell transmission do not match with this set of coordinates, it uses the following set of coordinates.

At step 2020, the coordinates of the cell transfer, relative to cell messages X and Y, are compared with the set of coordinates where 1) X is non-zero an odd number, and Y is an odd number or 2) X is an odd number, and Y is a positive odd number or a negative even number. If the cell transfer has coordinatesbefore(even≠0, odd) or (Cbefore(odd, odd or even), then at step 2022 block CBU in the cellbefore(even≠0, odd) or (Cbefore(odd, odd or even) sends a message only within cellbefore(even≠0, odd) or (Cbefore(odd, odd or even). If the coordinates of the cell transmission do not match with this set of coordinates, it uses the following set of coordinates.

According Fig. 21, at step 2102, the coordinates of the cell transfer, relative to cell messages X and Y, are compared with the set of coordinates where X is zero and Y is nonzero positive even number. If the cell transfer has coordinated the ATA before(0, +even≠0), then at step 2104 unit CBU in the cellbefore(0, +even≠0) sends a message to the blocks OBU in S1, S2, S3, S5 and S6 cellbefore(0, +even≠0), and blocks OBU sends a message to the CBU units in cells that have S4, S5, S6, S2 and S3 close to S1, S2, S3, S5 and S6 cellbefore(0, +even≠0), respectively.
