This invention relates to cellular radio communications, and more particularly to assigning radio channels in such systems.

History of previous development

When implemented system of cellular communication, first audiosvyazi and mobile subscribers using the methods of analog modulation. Accordingly, in mobile subscribers mobile radiotransmiteri (receiver-transmitters) at that time were also able to send and receive radio signals only on radio frequencies assigned to them within the range of fundamental frequencies and could communicate only by using the methods of analog modulation.

Over the years, with the expansion of the use of cellular radio systems, a limited number of basic frequencies established by the organizations in charge of communication for this use has become increasingly saturated, leading to more frequent cases of call blocking due to the fact that the frequency of the communication channel has become unavailable for use by the sending or receiving the call by the subscriber. To reduce the level of congestion in cellular radio communications, for use in such systems were given an additional frequency band, called the extended frequencies.

This has created an increased number of communication channels in each system, all added channels of communication were extended frequency band to accommodate a greater volume of traffic (information exchange) and a greater number of subscribers. However, it was necessary to design and manufacture new the main frequency" but also on radio stations within range extended frequency". At this time, the relationship in both frequency bands was done using analog modulation. However, since then, had to be mobile transceivers operating in the system and can operate in the range of fundamental frequencies, and the extended range of frequencies, and mobile transceivers that could only work in the range of fundamental frequencies, it became necessary that each mobile station can identify for their system frequency capabilities after a search of access to the communication channel, so that the assignment of the channel has occurred in accordance with the specific frequency wireless transceiver requesting the connection.

When the possibilities of radio communication channels existing between the mobile and base stations were added digital modulation methods, new devices were equipped with radios so-called type "dual mode". Such mobile transceivers can operate with the methods of analog modulation and digital modulation methods as in the range of fundamental frequencies, and the extended range of frequencies. This additional capability di, and the reason that you want to evaluate the system when assigning a communication channel for seeking access to the mobile station.

In traditional cellular radiotelecommunication systems algorithms of decisions needed to enable the system to assign cash the communication channels of the mobile stations as a function of its capabilities in terms of frequency/modulation, were hard-coded in the software cell switch. Although these methods adequately solve the problem in question, ensuring that each mobile station is assigned only one channel of communication that will work with the specific features of the station, they did not create the built-in flexibility of the system for allocating communication channels by taking into account other parameters in addition to frequency and modulation. For example, there is no possibility to allocate communication channels as a function of the priority of service provided by a particular mobile subscriber, or assign a specific communication channel depending on the nature of the services provided to the subscriber at the time of connection with him.

The objective of the invention is to provide the following benefits and opportunities. It would be a definite advantage to give vozmozhnastami options for accommodation and assignment of communication channels to optimize services provided to the subscriber in the framework of the system. It would also be desirable to create unique options for priority call processing within the system as a function of classes of services, abhirami individual subscribers.

Summary of invention

In one aspect of the present invention includes the allocation of communication channels within a cellular telecommunication system by assigning call type for each request communication channel received by the system.

Available in a cell system, the communication channels are distributed according to pre-selected groups of communication channels, and each group is associated with one or more specific types of calls. Each request received by the communication channel assigned to a group of communication channels on the basis of determining the call type. Then select a communication channel from the assigned group of communication channels associated with a call type and the call associated with the request going through the communication channel assigned to the selected communication channel.

In another aspect of this invention, the communication channels are selected within a cellular telecommunication system by pre-determining some characteristic combinations as pre-op is received via the communication channel, and the call type associated with a predetermined combination, the nearest to the characteristics of the request is accepted so the type of call request communication channel.

In another aspect of this invention, the communication channel is selected within a cellular telecommunication system, in which one or more characteristics are determined by one or more values, and at least one of each of the values is selected as the value that is installed by default. In addition, the characteristics of the request of the communication channel are compared with characteristic combinations associated with each of the predefined types of calls, and individual characteristics of the request communication channel sequentially modified by re-installation of one of its defining values for its value set by default, as a reaction to the inability to get an exact match when comparing.

Modified characteristics of the request communication channel using each of the successively modified values are consistently repeated stages in comparison with the characteristic combination associated with each predefined type of calls. The type of calls that the light is animalsa as the type of call request communication channel.

In another aspect, the system according to the present invention includes a means for determining the call type associated with the request for the acquisition of a specific communication channel coming into the system. Determining the call type based on the capabilities of the mobile stations, on the characteristics of the call and the characteristics of the subscribers. There are means for communication of the list of groups of communication channels with the given call type on Postovoi basis. The call type is used to define a group of communication channels, from which is selected the communication channel to assign his call.

Detailed description

In Fig. 1 for the beginning of the traditional system of cellular communication of the type which is mainly present invention. As can be seen from Fig. 1, an arbitrary geographic area may be divided into a number of adjacent areas covered by radio signals or by cells C1-C10. Although for purposes of illustration, the system shown in Fig. 1, contains only the ten hundred, can be clearly understood that in practice a number of hundred will be much more.

Within each of the hundred C1-C10 is associated base station is designated as one appropriate station from a number of base stations B1-B10.

Each of the base stations B1-B10 contains the transmitter, receiver and controller of the base station, as is well known in the art. On Phi is nenapravlenie antennas. However, in other configurations, cellular radio base stations B1-B10 may be located about the periphery or otherwise separated from the center of hundreds of C1-C10 and can cover the cells C1-C10 radio frequency signal either Omni-directional or directional. So the image of the cellular radio system of Fig. 1 is shown only for illustration purposes and is not intended to be limitations on the possible implementation of a cellular radio system in which the present invention is implemented.

The cellular radio system of Fig. 2 may include one of an alternative implementation of the controller base station supporting multiple base stations, as, for example, in the case of a digital radio system, which is currently implemented in European countries in accordance with the so-called GSM. In such a cellular radio system has one or more mobile switching centers (MCC), and each of them can handle a group of base station controllers.

Forth in Fig. 1 within a hundred C1-C10 you can find a number of mobile stations M1-M10. In Fig. 1 shows only ten mobile stations, however, you must realize that in fact a number of hundred mobile is CLASS="ptx2">

Moreover, although some of the hundreds of C1-C10 cannot detect mobile stations M1-M10, you need to understand that the presence or absence of the mobile stations M1-M10 in any particular cell C1-C10 in practice depends on the willingness of the mobile stations M1-M10, which can travel from one location in a cell to another or from one cell to an adjacent or neighboring cell, and even from one cellular radio system served by MCC, to another such system.

Each of the mobile stations M1-M10 is capable of initiating or receiving a telephone call through one or more base stations B1-B10 and through a mobile switching center (MCC). Mobile switching center MCC is connected via communication lines, for example, by means of cables, with each illustrated base station B1-B10 and landline public switched telephone network public PSTN, not shown, or a similar fixed network which may include integrated system digital network (ISCS). Appropriate connections between the mobile switching center MCC and the base stations B1-B10 or between a mobile switching center MCC and the PSTN or ISCS not fully shown in Fig. 1, but the eat one mobile switching center, and that each additional mobile switching center connected with another group of base stations and other mobile switching centers via cables or via radio channels.

Each MCC can be controlled in the system by providing communication between each of the base stations B1-B10 and the mobile stations M1-M10, being with him in the relationship.

For example, MCC will manage the search by calling mobile station, which is located in a geographic area that is serviced by its base stations B1-B10, in response to receiving the challenge sent to this mobile station, assigning a radio channel, the mobile station the base station after receiving the response to the search call from this mobile station, and transmission connection with a certain mobile station from one base station to another, which is caused by the fact that the mobile station moves through the system from cell to cell, and the connection is not terminated.

Each of the hundred C1-C10 endowed with a number of communication channels or speech channels and at least one channel access or control, such as managing communication (UCPS). The control channel is used for control or Supervisory control of mobile stations by means of information transmitted to these devices or received from them. Such information may include incoming call signals, send ringtones, Signa is achene communication channel, operating instructions and instructions for "transfer", when a mobile station moves from the coverage area of one cell in the service area of another cell. Control channels and communication channels can operate in either mode analog modulation or digital modulation, or in the mode of their combination, and at a certain frequency relay inside the main frequency range or within the extended frequency range or in combination.

As discussed above, the radio channels between the base stations and the mobile stations may be within one of a number of frequency bands, for example in the primary frequency band and in the extended frequency band, and may use one of a number of modulation techniques, for example, or analog, or digital. Separate transceivers (trxs) the mobile station can be capable to work only in one frequency band and only one method of modulation or the same in all bands and all methods of modulation, depending on when it was manufactured transceiver and other factors. For this reason, it is required that the cellular system can identify the type of mobile station, requesting the assignment of a communication channel, and to allocate Cana the communication with this station will occur on the selected channel. In order to achieve this goal, the system earlier work by using a scheme of assigning or allocating a communication channel of the type specified in the table in Fig. 2. Here in the left column 11 can be seen that the system must first determine the characteristics of the mobile station associated with capacity modulation, i.e., either analog or dual mode (analog and digital), and also related to its frequency capabilities, i.e., either the basic, advanced band (both the primary and secondary frequency). After determining the characteristics of the mobile station, requesting the assignment of a communication channel assignment is also based on the priority of the available types of channels, as shown in columns 12 to 14 in Fig. 2. For example, the first (and only) choice for existing mobile station capable of analog modulation only within the group of basic frequencies, consists in attributing to the analog communication channels with a frequency that is within range band of fundamental frequencies. There is no second and third choice for the mobile station, the request which has such characteristics. However, the mobile station is ove the first choice of the analog channel, inside the extended range, and the second selection analog modulation inside the main frequency range. Similarly, mobile station with a dual-mode was attributed to the communication channel based on the first digital channel, the second choice advanced analog channel and the third selecting analog channel inside the main frequency range. This scheme assigning communication channels are usually hard-coded in software MCC, control base station that allocates a communication channel, and functionally performs the task of ensuring that communication channels are assigned only those mobile stations that require performance of this particular mobile station. This method of assigning the communication channel shown in Fig. 2, does not provide the system operator with the flexibility or change the sequence of operations of assigning a communication channel, either in the introduction taking into account additional characteristics or in determining the assignment of a communication channel.

The system according to the present invention introduces an increased level of flexibility in the procedures for assigning communication channels due to the fact that allows the operator si is s criteria.

For example, the present system involves the capture of appropriate communication channels in the system based on the capabilities of the mobile stations for which these channels are selected, the characteristics of the calls in which the requested channels, and on the basis of the characteristics of subscribers, i.e., based on the nature of the subscriber's equipment, and classes of services, which were abnromal this subscriber. The implementation of this system involves the process of measurement of a request for a communication channel with a predetermined call type and then selecting the communications channel from a group of communication channels that are defined for this call type. Types of calls and group communication channels can be determined by the fixed system operator, depending on the characteristics of the system itself. In the system of the present invention is provided by the connection list of the groups of communication channels with the given call type on Postovoi basis. The communication channels can also be connected in groups of communication channels on Postovoi basis and in each cell stores a list of non-performing stations for each group of communication channels.

In Fig. 3 presents a block diagram showing the system of assigning a communication channel, constructed in accordance with the present invention, in which the queries of C is CI (traffic) channel connection with the mobile station, for example, sent the call, received call, the transmission of a communication, etc. For obtaining the request for the capture of the communication channel in the operator 21 should determine the type of call, the operator 22 and then on the basis of this determination, the choice of communication channel to the operator 23, i.e., the selection of the appropriate communication channel from the available pool of 24 channels of communication.

The selected channel is assigned to the operator 25 and the call is established on the link. When, Director of communications channels, is requested to capture a communication channel in a given cell in the operator 21, she begins the process that compares the features of the received query with the characteristics of a predetermined set of call types. Each type of calls in this set represents a unique combination of characteristics of the mobile station, subscriber and call. For example, the characteristics of the mobile station may include the possibility of modulation of voice messages, i.e., only analog or dual mode; the possibility of frequency bands, i.e., the basic frequency or extended frequency; and energy classes, i.e., from 1 to 8, which indicates the type of the station is a mobile, transportable or portable. Used characteristics of the subscriber can, for example, be the category of elite gadgets is in service, provided to the subscriber in the system. These classes of service for the mobile subscriber, for example, may include priority service, information service providing information, promotion calls and much more, depending on the nature of the services provided by the particular system. Moreover, the characteristics of the services provided to the mobile station, may include all of the characteristics defined by the different reactions of the specifications of CCITT standards, ANSI standards or other standards developing organizations, including the transfer on no answer, transfer busy channel, technoparty calling, call waiting, promotion of incoming calls, setting fees for sending calls, instant service, tracking deliberately offensive call, privacy of speech, message confidentiality, message waiting, the selection of priority access and channel services extension phone, selective call acceptance and management of voice mail network. Finally, characteristics of the call can be like that relate to a call, such as access to call, for example, forming, finishing, no load channel, and so is the result of the comparison of the call with various pre-defined sets of call types, the system operator 22 selects the type of call that best represents the full specifications of the request for the capture of the communication channel.

In some cellular systems, such as systems that meet the standards for digital radio communications GSM in the near future will be a mixture of mobile stations with different capabilities, and some of them are only working at full speed speech coders and some have speech coders, working at full speed and half speed. It is likely that there occurs a difference in the quality of communication channels to support mobile stations with half rate coders in relation to mobile stations with full speed encoders. In the GSM system the mobile station using a high-speed speech coder operating at the bit rate 13 kbps, while the mobile station using half rate speech coder operating at the bit rate is only 6.5 kbit/m as the result of a call using half rate speech encoding, required only the time interval in every one second. Therefore, the mobile station using half rate speech encoding, will be able to use the same physical is audiosystem can also be a mixture of mobile stations with a variety of antennas and without such diversity. In such cases there may be a difference in quality between that channel that could support a variety of antennas of the mobile station, and the running of the mobile station without diversity antennas. One way to achieve diversity is to use two different receiving channels affected by fading (fading), independently from each other. The risk that on both channels at the same time will be adversely affected by a profound failure characteristics of the fading is relatively small. This method uses two antennas, independently receiving the same signal and therefore in different susceptible to sinking.

The above-described characteristics of the mobile station used in the present invention may also include a velocity of the mobile station, i.e., speed and/or half rate speech coders. Such characteristics of the mobile station may, in addition, to enable the antenna, for example, diversity antenna.

In Fig. 4 is a diagram depicting an example of the "tree of types of calls and showing the manner in which you can define a call type by evaluating some dnoi characteristics "A" (which may be characteristic of either the mobile station, either subscriber or call) options, as an illustration, may include either the value of a0accepted value, accept the default, or the value of a1.

Similarly the characteristic "B" can be determined by a parameter that has a value of b0(the value taken by multiplication) or the value of b1. In addition, the characteristic "C" can be determined by a parameter that has a valueabout(value, default) or the value of the c1. In the right column of Fig. 4 presents a number of predefined types of calls, which might enter into the system, there are, depending on the specific characteristics of the call, based on the values connected with these characteristics. As can be seen from the tree types of calls in Fig. 4, if the value at index "0", this value is the default, and the characteristics are modified in the order C-B-A, then

a) to request the characteristic values of a0b1c1with him will be to connect the type of calls ARTICLE2;

b) request the characteristic values of a0b1c1will be modified in a1b1c0and with him will be associationthe, in order for each and every possible combination of characteristics, there was a call type. If for a specific combination no call type, the values of the individual characteristics consistently modified (in the order selected) to its value to the default, until the establishment of a particular type of call. As again shown in Fig. 4, this drawing shows five pre-defined call types, denoted ST0- ST4. Three additional branches of the tree types of calls are not marked to illustrate the fact that not every value of each characteristic should result in a specific type of call, and the system is able to manage the assignment of the type of call the nearest combination of characteristic values that can be set.

On the block diagram of Fig. 5 shows the procedure by which the system selects the type of call that you want to connect with a specific incoming call as a function of the characteristics of the query and as a factor in their power. The sequence of operations begins at the operator 31 with a request for the communication channel. The operator 32, the system receives specific characteristics associated with the request, and finds the branch NAA. The operator 33, the system first establishes whether there are any pre-defined call types, the corresponding branch of the tree, the particular combination of characteristics obtained. If so, the system associates this specific type of call request to the operator 34, and the sequence ends in the operator 35. However, if the operator 33 no call types that are specific to the characteristics defined in the query, the system goes to the operator 36 and sets one of the characteristic values on its value to the default, and then the operator 37, the system finds the branch on the tree types of calls, which corresponds to the modified characteristics of the query. The system then returns to the operator 33 in order to determine whether there are any pre-defined call types, the corresponding branch of the call tree that contains the modified characteristics. The sequence of operations continues to be obsessed with passing on a pre-selected sequence of modifications of characteristics as long as each call will not be connected with the call type, depending on the nearest match with the already modified charactised in accordance with the procedures of Fig. 6.

As shown in Fig. 6, the system begins to work in the operator 41 and the operator 42 retrieves a list of groups of communication channels associated with the selected call type defined for the request being processed communication channel. The operator 43, the system asks whether there are in this list any groups of communication channels. If not, the system proceeds to conclude, the operator 44 about the fact that you cannot choose the communication channel, and the sequence ends in the operator 45. However, if the operator 43 is established that in this list there is one or more groups of communication channels, the system goes to the operator 46 and selects a group of communication channels from the list in accordance with the sequence of operations of first choice. Then the operator 47, the system asks whether there is a selected group of communication channels any cash links. If this is so, then the operator 48, the system selects the communication channel in accordance with the second sequence of selection operations and ends in the operator 45. If the operator 47, the system establishes that no cash of communication channels in the selected group, it goes to the operator 50 and asks whether this list any other group of communication channels. If the operator 50 in the list were additional groups of communication channels, switches the system operator 53, where it selects the next group of communication channels from the list in accordance with the first sequence of selection operations and returns to the operator 47 to ask whether in the same group any communication channels, as it did earlier.

The first sequence of operations determines, as used in the selection process, the list of groups of communication channels associated with the call type.

Another sequence of operations can be defined on Postovoi basis for each call type defined in the system. The possible implementation of the first sequence of operations can, for example, to specify that a certain number of communication channels in certain bands allocated for a specific call type, and set the order in which groups are viewed to find a group of available channels. In addition, the sequence of operations may determine that each time you view a list of groups of communication channels, some channels of communication, previously designated as reserved for certain types of calls that can be made available for other types of calls, and can set how many times you want to view in connection selected, the second sequence of choice sets, as from this group is selected unoccupied channel. On Postovoi basis, it is possible to install another sequence of operations for each group of communication channels defined in the system. Possible implementations of the second sequence of operations can be, for example: "first - come, first-served basis, "last come, first - served basis, based on the transmission quality of the communication channel, etc.

In Fig. 7 shows a block diagram of the overall procedure associated with the choice of the communication channel in accordance with the methods of the present invention. As shown in the drawing, the characteristics of the request of the communication channel are injected from the channel 62 to a point 61 of the decision together with a set of predefined combinations of characteristics of the operator 63. The decision to assign a specific call type based on the characteristics of the query is displayed in the channel 64. The system then makes the input to the second point 65 decision-making, introducing a collection of communication channels associated with the call types (groups of channels) of the operator 66.

Group (group) communication channels associated with a particular type of calls displayed in the channel 67 and introduced into the point 68 of the channel selection together with ides. Thus, it is possible to see that the establishment of the various parameters involved in the selection of the communication channel in the circumstances, is extremely flexible in the system according to the present invention and gives the system operator of cellular communication the ability to create desired in the specific case of the system configuration in accordance with the fact that in this case it is necessary. For example, the specific characteristics of the request communication channel to which the system responds can get together with a pre-defined combinations of characteristics that sets specific types of calls. In addition, a collection of groups of communication channels that are associated with specific types of calls, can be determined flexibly. Finally, the sequence of selection operations, used for selecting a group of communication channels, and to select a specific channel from a group of communication channels can be defined depending on individual characteristics and preferences of the operator.

Each operator can make the appropriate choice and, accordingly, to identify the individual characteristics used in the implementation of the system according to the present invention. In Fig. 8 shows consistently is accordance with the present invention. Since the operator 81, the operator first defines new types of challenges in the operator 82, who must learn the system. In the statement 83 the system asks whether there are new required groups of communication channels, and, if they are transferred to the operator 84, where it defines a new group of communication channels.

The system then assigns a specific communication channels to new groups of communication channels in the operator 85. The operator 86 the system associates the group's communication channels with the new types of challenges. However, if the operator 83 did not need new groups of communication channels, the system goes directly to the operator 86 in order to associate a group of communication channels with any new call types defined in the operator 82. In statement 87, the system establishes a communication channel and a sequence of selection operations of the group of communication channels that should be used in the system, and operator 88 reserve communication channels for new types of challenges. The sequence of operations ends in operator 89.

As you can see, the system operator of cellular communication there is a possibility to reserve a number of communication channels in the group of communication channels for specific purposes. The number of remaining Unallocated communication channels in the channel group relations is the group equal to the number of reserved channels or less, access to these remaining channels can only get requests, leading to a group of call types. This allows the characteristics of the request channel of communication, which include some necessary for this case the configuration of the challenges, such as priority service and other classes of service provided by the system.

As can be seen from the foregoing, the present invention provides a cellular system be in charge requests of the logical communication channel and poradochnim way to optimize link utilization, and customer service provided by the system. It allows optimal use of valuable system resources, such as high-quality communication channels, and at the same time makes the system highly sensitive to the requests of the communication channels that deserve such treatment.
