Disclosure of inventions

However, because portability is becoming more important in the mobile communication terminal, there is a problem, namely, that it is difficult to realize high quality image for video telephony due to the limitations of resolution and monitor size.

On the other hand, in recent years, telephone services based on IP Protocol, using a technique referred to as VOIP (voice over IP)were widespread, and these services IP telephony become cheap or free. However, when video communication is implemented using VOIP, if the VOIP functionality is implemented in the framework of the mobile communication terminal, the complexity and size of the system tends to increase, so the cost of the system may increase.

In addition, generally speaking, the mobile communication terminal must be periodically re-charged, for example, by setting the mobile communication terminal in charger rechargeable batteries, so it can not be tolerated during charging, and thus the mobility is not so is important for use during charging, so it is possible to develop a system using a peripheral device.

Accordingly, taking into account the above circumstances, the problem to be solved by the present invention is to provide a video system, base station device, television, a set-top box and the way video telephony, in which video communication through high-quality images can be performed using the (video)camera, which is equipped with a mobile communication terminal such as a mobile phone, PHS or PDA.

To solve the above problems the present invention includes: a mobile communication terminal capable of receiving and transmitting to the base station of the Radiocommunication put moving images and negotiations; Autonomous base station, configured to transmit and receive on the basis of the communication Protocol that is used between the base station of radio communication and mobile communication terminal moving images transmitted to the base station radio communication; and a monitor configured to display the moving images taken offline base station.

In accordance with the present invention, as described above, it is possible to display on a television receiver or a monitor of a personal computer and the such through Autonomous base station of the moving image, transmitted and received between the mobile terminal and the base station radio, and implement video system with high quality and a large screen by displaying images on the monitor. In addition, in the case of the present invention, since the Autonomous base station uses the same base station radio communication Protocol (for example, the PHS Protocol) to perform transmission and reception of moving images by using a mobile communication terminal, the user can perform video telephony without knowing which station (base station radio or stand-alone base station) is used to route the transmission of information.

In the case of the present invention, along with the fact that you are using the same Protocol as in the base station radio communication is possible, in accordance with the needs of the user, to enable the sending and receiving of moving images on the basis of the Protocol (for example, Protocol wireless LAN), which differs from that used in the base station radio.

In the case of the above-mentioned invention, it is preferable to provide a charger of the battery acting to hold the mobile communication terminal on the monitor and charge the mobile terminal of the light is I. In this case, it is possible to keep the mobile communication terminal on the monitor and make video telephone communication during the charging of the mobile communication terminal.

In the case of the above invention is preferable to additionally provide the content server located in the communication network, which is created by the interconnection of communication lines, and operable to deliver data content including a moving image; TV the set-top box operable to receive data content delivered by the content server via the communications network; and a switching unit, operating to selectively display a moving image taken by an Autonomous base station and subscriber television console. In this case, it is possible to use the function set-top boxes designed to output and display the contents to carry out a video system so that it no longer was required to provide a number of systems with redundant functions, and thus can be implemented in a compact structure.

In the case of the above invention is preferable to additionally provide the processing unit connections acting to perform the transmission and reception of voice data by means of the mobile communication terminal based on the communication Protocol, used between the base station of radio communication and mobile communication terminal, and a signal processing unit, the current to the voice data transmitted and received by the processing unit connections, be converted into IP packets and back, and to send and receive IP packets via the communications network, which is created by the interconnection of communication lines. In this case, it is possible to use a cheap service IP-telephony over an IP network, in addition to radio communication via the base station radio, and via this link cost for video telephony may be reduced.

Video system in accordance with the above invention is preferably equipped with a relay server, applicable to forward transmitted and received IP packets between the mobile terminal and another mobile communication terminal, in this case, when data is received from stand-alone base station and from the base station radio communication relay server selects one of the standalone base station and the base station radio communication based on the identifier and a data table in which are registered the priority order for the standalone base station and base station radio, and connects the selected device with another mobile communication terminal.

The implementation of the invention

(Full configuration of the communication network)

Variant implementation of the present invention will be explained with reference to the drawings. In the case of this variant implementation, it is assumed that the communication network includes mobile phones, and IP phones, and video telephony system according to the present invention implemented as part of this communication network. Figure 1 illustrates the entire configuration of a communication system in accordance with this embodiment. As shown in figure 1, in the case of this variant implementation, the connection to the IP network 1 through the radio terminal 90u mobile communication through the base station 3B radio or stand-alone base station 100u.

The IP network 1 is a network connection that is created by the interconnect lines of communication such as wired and/or wireless telephone line(s)selected(s) line (s) and the like, including network LAN. The IP network 1 is also connected to the computer 80u, in which is installed a software application designed to perform the process of connecting the call, the terminal 70u and 26 IP phone that is connected with the stand-alone base station 100u and capable of performing processes such as the process of digital encoding of speech signals bandwidth, etc.

Terminal 70u IP phone is in the house 20 of the user to whom that is a permanent place of residence for a user U, and assigned the telephone number [050-xxxx-]. In addition, the terminal 26 of the IP phone is in the house 25 user, which is the permanent residence of another user, and assigned the telephone number [050-wuwu-] and IP address [uuu].

In addition, in the case of this variant implementation, the IP network 1 is connected to the network 2 PSTN (public switched telephone network (PSTN), the PSTN), which provides telephone communication using the switching system lines through the gateway 1G for the conversion of the predetermined signals. For transmitting and receiving signals, voice band telephone device 31 of the fixed line connects to the PSTN 2. Telephone device 31 of the fixed line installed in the institution 30 user U, and assigned phone number [03-xxxx-]. In addition, in the case of this variant implementation, the IP network 1 is connected through a gateway 1G network 3 mobile telephony to provide mobile telephony services. Terminals 90u and 52 mobile connects to the network 3 mobile phone via the base station 3B radio.

Terminal 90u mobile is worn by the user U and can be used for mobile communication, and is assigned a phone number [070-xxxx-]. In addition, the terminal 52 of the mobile phone is mobile is elephony apparatus, which is being used by another user, the appropriate home 25 user host terminal 26 IP phone, and assigned phone number [090-wuwu-].

Outside the building, the terminal 90u mobile communication is used to perform information exchange with the base 3B station of radio communication in accordance with the PHS Protocol, while the IP network 1 can be accessed via the base station 3B radio communication via the network 3 mobile phone, so it is possible to perform a call using the IP phone via the IP network 1 based on VOIP. In addition, the moving image is transmitted to another terminal 27 mobile and accepted from him and the like through the base station 3B radio during a telephone conversation, to provide the functionality of a so-called video telephony.

Thus, in the case of terminal 90u mobile, although the radio communication with the stand-alone base station 100u can be performed using the PHS Protocol, which is the same Protocol as that used in the base station 3B radio, in the house 20 user through the IP network 1 may be implemented IP telephony by accessing the IP network 1 through off-100u base station. In addition, the terminal 90u mobile communication can be used to aeginetia with Autonomous 100u base station through a wireless LAN such as based on the IEEE (Institute of electrical and electronics, IEEE) 802.11 and IP telephone communication can be performed through the wireless LAN. Connection with PHS or wireless LAN is switched automatically in accordance with the communication environment (condition of electromagnetic waves) or manually under the control of the user. It should be noted that although for exchanging information with the base station radio in an exemplary embodiment, the present implementation uses the PHS Protocol, it is possible to use any of a variety of ways such as FDMA method (multiple access frequency division, FDMA equipment), the method TDMA (multiple access with time division, mdvr), method (CDMA multiple access, code-division multiplexing, mdcr) or mode W-CDMA (wideband multiple access code division channels, W-mdcr).

Autonomous base station 100u modem is a device that was developed by adding the functions of an Autonomous base station Protocol-based PHS and functions of wireless LAN dedicated adapter terminal or terminal IP phone, and assigned IP address [HHH], so that an IP telephone communication can be performed using connected to this terminal 70u IP phone. In addition offline 100u base station is used in which the quality of the terminal receiver moving images for the reception of moving images, transmitted and received between the terminal 90u mobile and the base station 3B radio communication using a communication Protocol, which is the same Protocol that is used between the base station radio 3V and terminal 90u mobile communications and IP telephony can be done using terminal 90u mobile communication through off-100u base station. In other words, in the case of this variant of the implementation of Autonomous 100u base station is used to perform functions equivalent to the base station 3B radio in a predetermined area in which may be received electromagnetic waves, alternatively, wireless communication, and thus, the user U may perform communication based on the PHS through off-100u base station even in a location that can't reach an electromagnetic wave from the base station 3B radio.

In the case of this variant implementation, the server connection call is implemented in the IP network 1 through the server 11 SIP server 12 and the database agent 13 call.

The server 11 SIP is a device designed to perform a connection process of the calling terminal 90u mobile communications, etc. In addition to this, the server 11 SIP is used to obtain information such as the IP address required to connect the call, and to transmit information to the server 12 database when the terminal 90u mobile connects to the IP network 1 through off-100u base station or computer 80u.

The server 12 and the database is a device designed for storing destination addresses (IP addresses, network Protocol addresses) in conjunction with information about users of the services of IP-telephony subscriber telephone numbers. Agent 13 call is a device designed to perform the process of connecting the call based on the information stored in the server 12 of the database. It should be noted that in the case of a call to the terminal 90u mobile communication, which is connected to the IP network 1 through Autonomous base station or computer 80u, agent 13 can be transmitted to the server 11 SIP information such as the IP address required to connect the call. It should also be noted that the corresponding functions provided by the server 11 SIP server 12 and database agent 13 call can also be implemented through an integrated hardware structure.

In addition, the IP network 1 is equipped with a server 10G relay intended for the forwarding of traffic to IP packets between the terminal 90u mobile and other VOIP device through the network 3 mobile telephone and the server 10G relay provided with the possibility of conversion between IP packets and voice on nami, transmitted and received between the terminal 90u mobile and the base station 3B and radio service IP-telephony over an IP network 1.

This server 10G relay receives from the terminal 90u mobile communication identifier to identify the Autonomous 100u base station and/or base station 3B radio, and if he accepted, and from Autonomous 100u base station and from the base station 3B radio server 10G relay selects one of the Autonomous 100u base station and the base station 3B radio communication based on the received identifier and a data table stored in the server 12 of the database, and connects the selected device to another VOIP device.

It should be noted that the server 10G relay according to this variant implementation provided with an opportunity to notify the base station 3B radio about the detach command terminal 90u mobile communication, when data is received from the Autonomous 100u base station and from the base station 3B radio, and selected is offline 100u base station while the base station 3B radio cancels the connection with the terminal 90u mobile communication in response to this notification. According to this configuration, the terminal 90u mobile communication can be preferentially (priorities) to use the connection through the core is th station 100u for IP phone call.

(Configuration of the video system)

In addition to this, the house 20 user has a video system. As illustrated in figure 2, this video system includes a terminal 90u mobile, Autonomous 100u base station, as described above, and the monitor 44 for displaying moving images, which are taken offline 100u base station. Terminal 90u mobile has a camera 42 in addition to that described above, and makes it possible to perform so-called video telephony through transmission of moving images recorded with your camera.

Autonomous 100u base station performs the transmission and reception of voice data using a mobile communication terminal according to the communication protocols used between the base station of radio communication and mobile communication terminal, performs the conversion between IP packets and voice data transmitted and received, and performs the transmission and reception of an IP packet through the IP network 1. On the other hand, television STB 41 is a device receiving content that displays the moving image transmitted from the terminal 90u mobile and IP network 1, selectively on the monitor 44.

The monitor 44 may be a television receiver, a monitor of a personal computer and the like, and the core is placed a tuner for receiving satellite broadcasting and radio signals near field communication, in the case of this variant implementation of the monitor 44 is connected with the stand-alone base station 100u through TV box 41 and is provided by the output of the video content that is delivered from the server 14 content located in the IP network 1, and is accepted and stored, television subscriber station 41. In addition, the video system in accordance with this embodiment is equipped with the charging device 43 battery: battery to charge the terminal 90u mobile and stable to hold the terminal 90u mobile on the monitor 44. This charger 43 is placed, for example, on the upper surface of the monitor 44 and is powered by electricity from a household wall socket in order to charge the battery terminal 90u mobile communication. Terminal 90u mobile is removable mounted on the charging device 43 of the battery and provides the option to allow calls without lifting the receiver in the installation state in which the terminal 90u mobile is rechargeable.

In addition, the video system in accordance with this embodiment is equipped with a television subscriber station 41 for receiving and storing content data delivered from the server 14 is possessed through the IP network 1.

Then with reference to figure 3 will be explained the configuration of functional blocks of the terminal 90u mobile and functional blocks Autonomous 100u base station in accordance with this embodiment.

As illustrated in figure 3, the terminal 90u equipped with a mobile communication unit 91 of the keyboard input unit 92 of the display unit 93 input/output speech signals, block 94, the signal processing unit 99 connection processing and the camera 42.

Block 91 keyboard is used to enter numbers, such as phone numbers, and characters. Data, numbers, and symbols, as entered through block 91 keyboard input is passed to the block 94 signal processing. This block 94 signal processing is connected with the chamber 42, and the moving image recorded by the camera 42 is passed to the block 94 signal processing.

Block 91 keyboard is used to enter numbers, such as phone numbers, and characters, and, as introduced, the signals are then input to the block 94 signal processing. Block 92 display is used to display the contents of the data which is entered through block 91 keyboard, the phone number of the caller, the moving image, as taken from the partner, conversation, etc. and is connected to the block 94 signal processing. Block 93 input/output receival equipped with a microphone and loudspeaker, and is used to send and receive voice signals of a frequency band in the block 94 and signal processing from him.

Block 94 signal processing is used to perform the conversion between digital signals in accordance with pre-established standard and voice frequency band and the image signals, which are received from block 93 input/output speech signals, block 92 display and camera 42 and passed on them. The block 94 signal processing is connected to the block 91 and keyboard input unit 92 display to send and receive data, such as phone numbers. For example, block 94, the signal processing can be implemented using the codec in accordance with the standards of ITU-TG a/b (international telecommunication Union, ITU, telecommunications).

Block 99 connection processing module is designed to perform communication with the server 11 SIP when connecting directly with the base 3B of the radio station through the block 97 PHS. More specifically, the block 104 connection processing passes on the basis of SIP (session initiation Protocol) to the server 11 SIP identifier (ID) of the terminal [U1234-5678], IP address [x'h'h'h'], userid [user_a] (polzovatelya) and password, as described above. In addition, when connecting directly to the base station 3B radio block 99 connection processing performed by the process is soedineniya call between the server 11 SIP terminal 90u mobile communications based on SIP (session initiation Protocol), that is, the processing of connection dial phone number [070-xxxx-], used by the user U. in Addition, the terminal 90u mobile communication provided by the block 95A transmission of registration information, the unit 95b storing user information and the block s store an identifier (ID) of the terminal.

Unit 95b store user information is used to store the user ID to identify the user U and the password associated with the user ID. In the case of this variant implementation are stored user ID [user_a] for user U and the password associated with this user ID. Also the user ID and password stored in the server 12 of the database in conjunction with phone number [070-xxxx-], used by the user U. When the terminal 90u mobile connects to the IP network 1, the user ID and password stored in the unit 95b store user information is automatically transmitted to the server 11 SIP together with the ID of the terminal, and through this it is possible to avoid a disadvantage that the user U must enter information such as user ID, whenever you are connecting.

When the terminal 90u mobile connects to the IP network 1, which may be used for communication with the server 11 SIP, block 95A transmission of the registration information, transmits to the server 11 SIP ID is notificator terminal identification terminal 90u mobile communication and address to identify the location of the terminal in the IP network 1, that is, the telephone number and IP address to identify the location of the terminal 90u mobile connected to the IP network 1.

In addition, the unit 95A transmission of the registration information may optionally pass to the server 11 SIP user ID and password corresponding to the user U. In this case, in accordance with the required level of protection is determined, transmitted, whether the user ID and password in addition to the terminal ID and IP address. Block C storage ID of the terminal is used as a storage unit, from which the terminal ID (terminal ID)assigned to the terminal 90u mobile communication, is transmitted to the block 95A transmission of registration information. In this case, the terminal ID assigned to the terminal 90u mobile communications, is an identifier unique to the terminal 90u mobile communication. In the case of this variant implementation uses a sequence number in the form [Uxxxx-xxxx], and the terminal 90u mobile is assigned [U1234-5678]. Meanwhile, the terminal ID is stored in the server 12 of the database in conjunction with phone number [070-xxxx-], used by the user U. alternatively, instead of a serial number in the form [Uxxxx-xxxx] can be used MAC-address (management of access to the transmission medium, UDS, MAC) terminal 90u mobile communication as a terminal ID.

The serial number is recorded in the flash memory and the like, so he could not be re-recorded for the purpose of illegal use of the services of IP-telephony. Accordingly, it is difficult to change the sequence number, and thus protection against illegal use of the services of IP-telephony can be improved.

In addition, the terminal 90u mobile communication units 97 PHS, which is a communication interface for wireless communication according to the communication protocols on the basis of the PHS unit 98 wireless LAN, which is a communication interface for local communication, such as wireless LAN, and the block 96 switching, designed to switch between block 97 PHS and block 98 wireless LAN.

Block 97 PHS is a module designed to perform radio communication according to the Protocol of the PHS base station 3B radio or block 106 provide Autonomous PHS provided in the Autonomous 100u base station. Block 98 wireless LAN module is designed to perform radio communication in accordance with IEEE 802.11, etc. with unit 107 of the wireless LAN provided in the Autonomous 100u base station. Block 96 switching connection is the switching switch designed for selective connection unit 97 PHS or block 98 wireless LAN with block 94 signal processing on the basis of the user is who manipulate through the block 91 keyboard and power of received radio waves, defined by the block 94 signal processing.

On the other hand, Autonomous 100u base station is equipped with a block 102, the signal processing unit 104 connection processing unit 105 IP network. The block 102, the signal processing module is designed to perform the conversion between IP packets and signals, speech and image and output when the connected terminal (terminal 70u IP phone or terminal 90u mobile communication) is not equipped with the ability to transform according to VOIP. Block 104 connection processing module is designed to exchange information with the server 11 SIP through the block 105 IP network. More specifically, the block 104 connection processing passes to the server 11 SIP identifier of the terminal [U1234-5678] for terminal 90u mobile communication, as described above, the user ID [user_a], password and a unique IP address [x'h'h'h'] Autonomous 100u base station, based on SIP (session initiation Protocol). In addition, when the IP address [x'h'h'h'] as transmitted is registered in the server 12 and the database unit 104 connection processing takes from the server 11 SIP information (parameter "expires" (expiration date) of the SIP header)indicating the registration expiration time of the IP address. The block 104 connection processing again transmits to the server 11 SIP IP address, user ID and password before expiration of the registration term at the core the ve information about registration expiration IP address as received, to re-register the IP address in the server 12 of the database.

In addition, the block 104 connection processing performs a process of connecting the call between the server 11 SIP terminal 90u mobile communication, i.e. the processing of connection dial phone number [070-xxxx]used by the user U based on SIP (session initiation Protocol). In addition, the block 104 connection processing periodically determines whether the terminal 90u mobile with offline 100u base station. If the terminal 90u mobile disconnected from Autonomous 100u base station, unit 104 connection processing notifies this fact to the server 11 SIP.

Block 105 interface (IF) network have an interface connected to the IP network 1. For example, block 105 network interface may be carried out in the presence of a LAN interface, such as 100BASE-TX (implementation of physical layer standard 100BaseT), in accordance with IEEE 802.3u. Incidentally, modem ADSL (asymmetric digital subscriber line, ADSL) can also be used to make a connection between the IP network 1 and the Autonomous 100u base station depending on the type of line connection used to access the IP network 1. The block 105 network interface provided with the opportunity to connect with the content server 14 in response to a request from a set-top-boxes 41, receiving the content data, which bring the camping from the server 14 content and output them to a TV box 41 through the block 108 switching.

In addition, Autonomous base station equipped with block 106 provide Autonomous PHS, which is a communication interface for wireless communication according to the communication protocols on the basis of the PHS unit 107 of the wireless LAN, which is a communication interface for local communication, such as wireless LAN, and block 108 switching to switch between block 106 provide Autonomous PHS unit 107 of the wireless LAN. Block 106 provide Autonomous PHS is a module designed to perform radio communication according to the Protocol of the PHS unit 97 PHS provided in the terminal 90u mobile communication. Unit 107 of the wireless LAN module is designed to perform wireless communication in accordance with IEEE 802.11, etc. with block 98 wireless LAN provided in the terminal 90u mobile communication. Block 108 switching is the switching of the switch, designed for selective connection unit 106 for Autonomous PHS or unit 107 of the wireless LAN unit 104 connection processing unit 105 of the network interface based on the user's manipulation through the switch 101A and the power of the received radio waves, a certain block 106 provide Autonomous PHS or Blo is ω 107 of the wireless LAN.

In addition, the block 108 to the switching of the connections provided by the possibility of switching between the moving image taken from terminal 90u mobile communication, and the moving image, delivered from the server 14 content in response to a request from a set-top-boxes 41 and displays them on the TV box 41.

(Scheme communication system)

Next, with reference to figure 1 will be explained the General scheme of the communication system in accordance with this embodiment, as described above.

For example, when the user out of the house 25 another user makes a call with the terminal 26 of the IP phone terminal 70u IP phone used by the user U, and placed in the house 25 user first agent 13 call receives data from the terminal 26 IP phone telephone number [050-xxxx]assigned to the terminal 70u IP phone with IP-address [uuu]. The agent then 13 call accesses the server 12 and the database based on the telephone number [050-xxxx-] quality is as taken.

In this case, for example, the server 12 and the database stores information as shown in tables 125 a and 125b phone numbers in figure 4. Agent 13 call gets the IP-address [HHH], which is an element of "Destination address (Priority 1)" (destination address (priority 1)) in table 125 a telephone number corresponding to [050-xxxx-], which is an element of "Assigned Telephone Number (phone number is assigned). Agent 13 call connects the terminal 26 of the IP phone and the terminal 70u IP phone based on IP addresses [HHH]received from the server 12 and the database, and the IP address [y.y.y.y], received from the terminal 26 of the IP phone.

In addition, the server 12 database under this option the implementation can store phone numbers for forwarding addresses that are transferred calls to a preset phone number. For example, in table 125 a telephone number assigned to the telephone number [050-xxxx-] is associated with the IP address [HHH]stored as the item "Destination address (Priority 1)", as described above, as well as with phone number [070-xxxx-] terminal 90u mobile, wearable by a user U, item Destination address (Priority 3)" (the destination address (priority 3)).

In the case of this variant implementation, as illustrated in figure 5, this table 125 phone numbers is made in the form of a multilayer structure including data 125C table lower the level, corresponding to the assigned phone number [070-xxxx-], and data 125C table lower level contain the IP address of the standalone base stations 100u connected to the terminal 90u mobile communication. For example, the IP address [x1.x1.x1.x1] placed in the institution 30 Autonomous base station 100u user U is stored in the "Destination address (Priority 2)" (the destination address (priority 2)), and IP-address [HHH] Autonomous 100u base station connected to a personal computer 80u used by the user U, is stored in the "Destination address (Priority 2)" (the destination address (priority 2)). It should be noted that the user U can save the phone number of the terminal 31 a regular telephone or a telephone number of the terminal 90u mobile phone in the server 12 and the database through the Internet and such.

In the case where the set of destination addresses stored in the server 12 of the database, the agent 13 call may connect the call to a designated telephone number ([050-xxxx-]) on the basis of the priority order of destination addresses.

For example, while the agent 13 call can cause the terminal 70u IP phone based on IP addresses [HHH], stored in the "Destination address (Priority 1)"if the terminal 70u IP phone does not return any response to the call agent 13 call within a predetermined time interval, the agent 13 call stops the calling terminal 70u IP phone is a and may cause the terminal 31 of the usual phone number [03-xxxx-], which is stored in the "Destination address (Priority 2)".

In addition, when the calling terminal 90u mobile agent 13 call makes a call to the terminal 90u mobile phone number [070-xxxx-] through the use of PHS, and, if a response is not returned within a predetermined time interval, the IP address of the corresponding Autonomous base stations can be used in turn to make the call to the IP phone. Meanwhile, the user U can change the priority order for sets of destination addresses stored in the server 12 of the database in accordance with the time of day by means of additional storing predetermined information in the server 12 of the database.

Through the actions of the server 12 and the database agent 13 call, as was discussed above, it is possible to transfer the call using the telephone number [050-xxxx-], used by the user U, the predefined telephone device in accordance with the location in which the user U is in.

In addition, in the case of this variant implementation, when the user U connects the terminal 90u mobile communication with the IP network 1 through one of the Autonomous base stations 100u, the IP address assigned to this Autonomous 100u base station, is set via the server 11 SIP as the "destination address"stored in the middle of the ore 12 database as explained above.

Accordingly, the user U can't take the call at the telephone number [050-xxxx-], for example, even when traveling and such, with offline 100u base station and terminal 90u mobile without changing stored in the server 12 database "destination" yourself by connecting terminal 90u mobile communication with the IP network 1 through Autonomous base station.

Because the communication system in accordance with this embodiment operates, as was discussed above, the user U can selectively use two telephone terminal, i.e. the terminal 70u IP phone and the terminal 90u mobile communication associated with the same telephone number [050-xxxx-], without changing the "destination address", etc.

In particular, in the case of this variant implementation, the offline 100u base station is used to perform communication with the terminal 90u mobile communication system based on PHS, and thus the user can make a call to an IP phone number PHS assigned to the terminal 90u mobile communication. Also in the case when the antenna adapter is used as a stand-alone base station 100u, removable attachable to the computer 80u is possible to use PHS phone in the same way, as usual, by carrying this is the antenna adapter and use antenna device for Autonomous PHS even in the location which radio waves cannot reach from the base station 3B radio, such as location abroad (as a remote), provided that a personal computer is available for connection with the IP network 1.

(Communication method using the communication system)

Below with reference to Fig.7 will be explained a communication method for a communication system in accordance with this embodiment. Figure 7 shows the sequence diagram showing the action of the communication system in accordance with this embodiment.

First, when the terminal 90u mobile communication connected with personal self 100u base station connected to the IP network 1, the personal self base station at step S10 transmits [070-xxxx-]assigned to the terminal 90u mobile communication server 11 SIP with IP-address [x'h'h'h'], appointed personal self 100u base station, by using the message "REGISTER") of the SIP Protocol. After receiving the message "REGISTER" the server 11 SIP at step S20 is transmitted from the request (with confirmation) - based algorithm (MD5 hash algorithm to protect) or similar.

When the value of the request is accepted, the personal self base station at step S30 transmits to the server 11 SIP is calculated in accordance with the MD5 algorithm or the like on the basis of the user ID is El [user_a], the password associated with the user ID, and terminal ID [U1234-5678], stored in the terminal 90u mobile.

Then, in step S40, the server 11 transmits a SIP server 12 and the database user ID [user_a], password, ID terminal [U1234-5678], phone number [070-xxxx-] and IP address [HHH] as taken from the personal self 100u base station.

The server 12 and the database authenticates the terminal 90u mobile communication based on the information received from the server 11 of the SIP, and the information stored in the server 12 of the database, and changes on the stage S50 element in the "Destination address (Priority 1)" [070-xxxx-] and the element in the "Destination address (Priority 1)" data 125C table lower level on the IP address [x'h'h'h'].

Then, the server 12 database at step S60 notifies the server 11 SIP that terminal 90u mobile communication is authenticated and that the elements Destination address (Priority 1)" updated. The server 11 SIP at step S70 notifies the personal self 100u base station that completed the registration on the basis of the server 12 and the database. Also, the server 11 SIP notify the registration term telephone number [070-xxxx-] and the validity of the registration of the IP address [x'h'h'h'] with reference to the parameter "expires" header of the SIP Protocol. When the above process is completed, the telephone number [050-xxxx], stored in the server 12 of the database is changed, as illustrated in Fig.6.

Below with reference to figure 5 will be explained to omnitele the connection of the calling terminal 90u mobile communication. For example, in the case when the terminal 26 IP phone makes a call to the telephone number [050-xxxx-], agent 13 call at step S80 takes the phone number and IP-address [y.y.y.y] terminal 26 of the IP telephone terminal 26 IP phone. The agent then 13 call at step S90 accesses information stored in the server 12 of the database based on the telephone number [050-xxxx-] as accepted. At this time, the agent 13 call at step S100 receives phone number [070-xxxx-] and IP address [x'h'h'h']that are associated with the telephone number [050-xxxx-], and recognizes that the IP address assigned to the personal self 100u base station, because the value of the "LF" (line feed character) is set to "1", as illustrated in Fig.6.

Call agent 13, therefore, at the step S110 transmits to the server 11 SIP IP address [x'h'h'h'] and IP address [y.y.y.y] terminal 26 IP phone. The server 11 SIP at step S120 connects the call from the terminal 26 of the IP phone terminal 90u mobile communication based on the information received from the agent 13 call. After that, the terminal 26 of the IP phone and the terminal 90u mobile communication start information exchange among themselves on stage S130.

Below will be considered a description of the process, when the terminal 90u mobile detaches from the personal self 100u base station connected to the IP network 1.

If not re-register the IP addresses of the personal self of the base is tanzihi 100u even after the expiry of the registration phone number [070-xxxx-], as is notified to the computer 80u at step S70, the terminal 90u mobile communication, coupled with the personal self 100u base station, called by the server 11 SIP at step S140.

When the terminal 90u mobile returns to the step S140 any answer, the server 11 SIP at step S150 determines that the personal self 100u base station is disconnected from the IP network 1. Meanwhile, in the case when only the terminal 90u mobile is disconnected from the computer 80u, personal self 100u base station can notify the server 11 SIP that terminal 90u mobile communication is disconnected in accordance with the SIP Protocol.

In the result of determination at step S150 or on the basis of notifications from the personal self 100u base station that the terminal 90u mobile communication is disconnected, the server 11 SIP notifies the server 12 and the database that the terminal 90u mobile phone or personal self 100u base station is removed in step S160. On the basis of the notification from the server 11 SIP communication between the telephone number [050-xxxx-] and a priority destination address for the telephone number [050-xxxx-], i.e. phone number [070-xxxx-], released in the server 12 and the database at step S170.

When the process at step S170 is completed, the information stored in the server 12 and database changes as Provillus is recorded in figure 4.

In accordance with the communication system and communication method in this variant implementation, the call to the telephone number [050-xxxx-] user U is connected to the terminal 90u mobile communication based on the IP address [x'h'h'h']transmitted from the terminal 90u mobile communication, and thus the user U can't take the call at the telephone number [050-xxxx-] terminal 90u mobile.

In accordance with this embodiment, since the IP address [x'h'h'h'], as transmitted from the personal self 100u base station, automatically set as a priority destination, getting precedence over the destination addresses that have been pre-stored in the server 12, a database, is it possible to avoid the disadvantage that the user U must manually change the destination address. Namely, the user U can selectively use two telephone terminal assigned the same telephone number [050-xxxx-], that is, the terminal 70u IP phone and the terminal 90u mobile communication, without changing the "destination address", etc.

In the case of this variant implementation, since the terminal 90u mobile is authenticated on the basis of the terminal ID transmitted from the terminal 90u mobile terminal ID stored in the server 12, a database, is it possible on the identify, should the service be provided to the terminal 90u mobile, without using the user ID and password corresponding to the user U.

In the case of this variant implementation, when the server 11 SIP reveals that the terminal 90u mobile is disconnected from the computer 80u or that the personal self 100u base station is disconnected from the IP network 1, the priority destination address as the set is removed from the register, and thus the agent 13 call may connect the call to the telephone number [050-xxxx-] on the basis of the destination addresses that are provisioned in the server 12 of the database when the terminal 90u mobile phone or personal computer 80u are disconnected from the IP network 1.

In the case of this variant implementation, the terminal 90u mobile is authenticated based on the user ID and password in addition to the terminal ID transmitted from the terminal 90u mobile communication, and thus it is possible to improve protection against illegal use of the service.

Also, in the case of this variant implementation, since the terminal 90u mobile communication unit is provided in addition s storage ID of the terminal, able only to read the ID of the terminal, while the block 73 of the transfer of the registration information, transmits the terminal ID read from the block s x is Anania ID terminal, it is possible to prevent the change user ID of the terminal, etc. and to improve protection against illegal use of the service.

In addition, in the case of this variant implementation, because the personal self base station is equipped with optional unit 72 storing user information, capable of storing the user ID and password, while the block 73 of the transfer of the registration information, transmits the user ID and password as stored in the storage unit ID of the terminal block 72 storing user information, it is possible to avoid the disadvantage that the user U must enter the user ID and password every time you are connecting.

(Scheme action video system)

The following will explain the action of the video system in response to pig and Fig.9. Incidentally, an example will be explained under the assumption that the user U is in the house 20 of the user and that the user U performs video communication with another terminal 27 mobile, equipped with video telephony through the use of terminal 90u mobile.

(1) the process of receiving the call

The first presents an explanation for the case when there is a call from another terminal 27 mobile communication. As shown in Fig, charging terminal 90u mobile is Noah communication begins when the terminal is installed 90u mobile charger 43 battery on the steps S101 and S102. On the other hand, the call is made from another terminal 27 mobile, and then the process of receiving the call begins with the terminal 90u mobile communication at step S103. It should be noted that in this example, since the terminal 90u mobile communication able to communicate with any base station 3B radio and Autonomous 100u base station, the terminal 90u mobile communication capable of performing a process of receiving a call via any device from the base station 3B radio and device 100u Autonomous base station, so that at step S104 determines which of the base station 3B radio and Autonomous 100u base station is used to establish a communication route.

In the case of this variant implementation, it is assumed that the priority of the Autonomous 100u base station registered in the table 125 for a connection when you have both the call and the base station 3B radio, and stand-alone base station 100u. Accordingly, at step S104, with reference to the table 125 is determined that the connection is established via Autonomous 100u base station, and the process goes to step S107. At step S107 route communication through the base station radio is disconnected by server 10G relay, and the server 11 connects SIP terminal 27 mobile and Autonomous base station 100u.

Meanwhile, in the determination process on this is e S104 is followed by the steps S105, and S106 to set the route communication through the base station radio in the case of, for example, when the communication route via the base station radio priority is specified or when there may be a connection between the terminal 90u mobile and Autonomous 100u base station. In other words, base station and radio terminal 27 mobile connected to each other through the server 10G relay at step S105, and the IP telephone connection is established via the base station radio at step S106.

Then after establishing a connection between the terminal 90u mobile communications and terminal 27 mobile Autonomous base station communicates with the terminal 90u mobile communication by blocks 106 or 97 for Autonomous PHS, or blocks 98 107 or wireless LAN to step S108 to start the transmission and reception of moving images. Then, based on the control commands of the user through the TV box 41, block 108 switching connections switches image (including speech)to be output to the monitor 44. Namely, when the television STB 41 performs image output delivered from the server 14 content over an IP network 1, the output path is switched to output the moving image video telephony taken from terminal 90u mobile communication, the and the monitor 44 via TV box 41. According to this configuration, video telephone communication is established between the terminal 90u mobile communications and terminal 27 of the mobile communication at step S110.

(2) the invocation Process

The following explains the case where the call is made to another terminal 27 mobile communication. As illustrated in Fig.9, the terminal 90u mobile first set on the charger 43 battery to start charging terminal 90u mobile on the steps S201 and S202. Then call process is performed by manipulating the terminal 90u mobile to call another terminal 27 of the mobile communication at step S203. Meanwhile, in this example, since the terminal 90u mobile communication able to communicate with any base station 3B radio and Autonomous 100u base station, the terminal 90u mobile communication capable of performing the process of the call through any of the base station 3B radio and Autonomous 100u base station, so that at step S204 determines which of the base station 3B radio and Autonomous 100u base station is used to establish the transmission path.

In the case of this variant implementation, it is assumed that the priority of the Autonomous 100u base station registered in the table 125 for a connection when the call is performed for the base station 3B radio,and stand-alone base station 100u. Accordingly, at step S104 is determined with reference to the table 125, the connection is established via Autonomous 100u base station, and the process goes to step S207. At step S207, the communication route via the base station radio is disconnected by server 10G relay, and the server 11 connects SIP terminal 27 mobile and Autonomous base station.

Meanwhile, the processes of determination at step S204 is followed by the steps S205 and S206 to set the route communication through the base station radio in the case of, for example, when the communication route via the base station radio priority is specified or when the connection cannot be established between the terminal 90u mobile and Autonomous 100u base station. In other words, the base station of radio communication and the mobile communication terminal 27 are connected to each other through the server 10G relay at step S205, and the IP telephone connection is established via the base station radio at step S206.

Then after establishing a connection between the terminal 90u mobile communications and terminal 27 mobile Autonomous base station at step S208 establishes communication with the terminal 90u mobile communication by blocks 106 or 97 for Autonomous PHS, or blocks 98 107 or wireless LAN to start sending and receiving of moving images. Then, based on the manipulation of the user h is rez TV box 41, block 108 switching connections switches image (including speech)to be output to the monitor 44. Namely, when the television STB 41 performs image output delivered from the server 14 content over an IP network 1, the output path is switched to output the moving image video telephony, as taken from terminal 90u mobile services on the monitor 44 via TV box 41 at step S209. According to this configuration, video telephone communication is established between the terminal 90u mobile communications and terminal 27 of the mobile communication at step S210.

(Actions and effects video system)

As was discussed above, using a video system in accordance with this embodiment is possible to display the moving image transmitted and received between the terminal 90u mobile and the base station 3B radio, on the monitor 44 through off-100u base station, and to make video telephone calls system with the availability of high-quality, large screen, displaying images on the monitor 44.

Also in the case of this variant implementation, as Autonomous 100u base station uses the same Protocol PHS, as the base station 3B radio to perform the transmission and reception of driving the Xia images using terminal 90u mobile the user can perform video telephony without awareness of what station (base station radio or stand-alone base station) is used for routing information.

On the other hand, in the case of this variant implementation, the wireless LAN with having a Protocol different from the one used in the base station 3B radio, can be used for transmitting and receiving moving images instead of the PHS Protocol, which is the same as used in the base station radio communication, and thus it is possible to choose a suitable communication Protocol in accordance with the communication environment.

Because there is a charger 43 battery provided to hold the terminal 90u mobile on the monitor 44 and the charging terminal 90u mobile communication in the case of this variant implementation, it is possible to easily hold the terminal 90u mobile on the monitor 44 and to charge the terminal 90u mobile communication for performing video telephony. In addition, in the case of this variant implementation, because there is a TV STB provided for receiving content data delivered from the server 14 content over an IP network 1, and the moving image, which is taken offline base is th station 100u or television subscriber station 41 on the monitor 44, are selectively displayed, it is possible to use the function set-top boxes 41, which is designed to output and display the contents to carry out a video system so that it no longer involve multiple systems with redundant functions, and thus can be implemented in a compact structure. In the case of the variant of implementation, as described above, it is possible to use a cheap service IP telephone communication via the IP network 1 through block 104 connection processing unit 102 for processing of signals, which are provided in the Autonomous 100u base station, in addition to radio communication via the base station 3B radio, and thus the communication cost for video telephony may be reduced.

In addition, in the case of this variant implementation table 125 a and 125b phone numbers are stored in the server 12 of the database to record the priority order for Autonomous 100u base station and the base station 3B radio, and, if data is received from the Autonomous 100u base station and from the base station 3B radio, select one of the Autonomous 100u base station and the base station 3B radio communication based on the identifier and tables 125 a and 125b phone numbers and connect selected the other terminal 27 of mobile communication, so who is the one automatically set an arbitrary communication route on the basis of the user settings in case and when the base station 3B radio, and stand-alone base station 100u are available for connection.
