The present invention relates, in general, to a subject of communication, and more specifically, to speech-language communications services in a communication system.

In the radio system, unnecessary and excessive transfers (data) by the user can lead to redundancy for other users in addition to reducing the bandwidth of the system. The surplus and super-measure transmission in the communication system may be caused by requesting the transmission of unnecessary data. The system for the speech application may require the use of certain broadcast parameters. In the course of the reception of speech services, the mobile station may request the transmission of such broadcasting parameters from the serving base station. Such broadcast parameters may include information on the type of speech modulation, data rate, encryption key, coding, speech channel frequency, and other information of this kind. Management of several base stations may be carried out by a general broadcast controller. So, while the mobile station is within the service areas of these base stations, the mobile station does not need to request a retransmission of speech parameters. However, when the mobile station moves to the service area of ​​the new base station, the mobile station may not have a reliable method of determining whether the new base station or the other broadcast controller is using it. In essence, the mobile station may request transmission of broadcast parameters every time it moves into the service area of ​​the new base station. Inquiring and receiving transmission parameters of the order may interrupt the speech services that are played in the mobile station, and lead to unnecessary and excessive transmission in the communication system. when the mobile station moves into the service area of ​​the new base station, the mobile station may not have a reliable method of determining whether a new base station or another broadcast controller is used. In essence, the mobile station may request transmission of broadcast parameters every time it moves into the service area of ​​the new base station. Inquiring and receiving transmission parameters of the order may interrupt the speech services that are played in the mobile station, and lead to unnecessary and excessive transmission in the communication system. when the mobile station moves into the service area of ​​the new base station, the mobile station may not have a reliable method of determining whether a new base station or another broadcast controller is used.

Inquiring and receiving transmission parameters of the order may interrupt the speech services that are played in the mobile station, and lead to unnecessary and excessive transmission in the communication system.

Thus, there is a need for a method, device and system to update the broadcasting parameters of the mobile station for speech services in the communication system.

Proposed method, device and system for effective use of communication resources for providing speech services in the communications system. The receiver receives the first identification of the broadcast controller from the first base station and the identification of the broadcast controller from the second base station. The controller connected to the receiver determines whether the first and second identifiers of the controller are associated (connected) with the use of a common set of broadcast parameters. When the first and second identifiers of the controller are associated with the use of a general set of broadcast parameters, the transmitter transmits the requested transmission of a new set of broadcast parameters.

After receiving a new set of parameters, the speech receiver uses a new set of broadcast parameters to receive speech services.

The features, tasks and advantages of this invention will become clearer in the detailed description, set forth below, when considered in conjunction with the drawings, in which the kernel numbering is used.

Generally speaking, new and improved systems, methods and devices are proposed for efficient use of communication resources for speech services in the communication system. According to various aspects of the invention, a set of speech parameters associated with one or a large number of control rollers broadcast. When using the first broadcast con trol through the first base station, receiving a second identification of the speech controller from the second base station initiates the process of determining whether the first and second identifiers of the broadcast controller are associated with a common set of broadcast parameters. According to various aspects of the invention, when the first and second identification of the control roller are not associated with the general range of broadcast parameters, the request is triggered by a new set of broadcast parameters. Described herein is one or more of the possible embodiments embodied in the context of the digital terrestrial radio communication system. Although it is negligible to use within this context, various embodiments of the invention may have been implemented in different environments or configurations. In general, various systems described here can be formed using processor-guided software, integral

circuits or discrete logic circuits. Data, instructions, commands, information, signals, symbols and elementary signals that can be made during the application process, preferably represented by electrons, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles or their combination. In addition, the blocks shown in each block diagram, may represent the stages of the method or hardware.

More specifically, various embodiments of the invention can be implemented in a radio communication system operating in accordance with the multiple-channel multiplication code-division method (CDMA, ΟΜΜ), which has been disclosed and described in various standards issued by the Association of Industrial Facilities communication (APE, TIA) and other organizations in the standards. Such standards include the TIA / EIA-95 standard, the TIA / EIA-IZ-2000 standard, the IMT-2000 standard, the IMI standard and the MC1EM, the contents of which are fully included in the contents of this application for the link. The system for data transmission is alsodetailed in "TIA / EIA / IZ-856 SISIT2000 NIDIRAJE ROOKSIZAIAAIGIPIEGYAZA ZRESTI TIASIAIOP", the contents of which is fully included in the contents of this application by reference. A copy of the standards can be obtained by applying to the following address: pv: //vdvdvd.3tsrr2. in the World Wide Web or in writing to the Department of Technology and Standards TIA, 2500 Mioioop Voiceo, AgioInfo, USA 22201. The standard is generally identified as the standard of the IMT, the content of which is completely included in the content of this application by reference, can be obtained by contacting the Support Office of the 3 SRR, mobile stations 102-104, respectively. Reverse link sig nali 107-109, although they may be addressed to one base station, may be taken at other base stations.

Base stations 101 and 160 can simultaneously communicate with the general mobile status. For example, the mobile station 102 may be located in the immediate proximity of the base stations 101 and 160, and may communicate with the base station 101 and 160. In the direct communication, the base station 101 transmits the direct line signal 106, and the base station 160 transmits the signal 161 direct link. On the downlink, the mobile station 102 transmits a feedback signal 107 that is to be received by the base stations 101 and 160. For transmitting the data packet to the mobile station 102, one of the base stations 101 and 160 may be selected for transmitting the data packet to a mobile station 102. On the return line of the '

The communication system 100 may also provide speech services for mobile stations. Mobile services may include receiving video or audio through base stations 101i and 160. In another possible embodiment, mobile communication may be broadcast

traffic or weather. In the broadcast system, one sig-nal can be transmitted simultaneously to a large number of mobile stations. A speech signal can be encrypted. Consequently, mobile stations may require subscription to such services. Before the use of mobile station services, it may be necessary to obtain encryption information from the base station. Additionally, the mobile station may be required to receive other broadcast parameters for reception of speech services. Speech settings may include a speech channel identifier, voice modulation information, data rate, key encryption, encoding, speech frequency, encryption and decryption keys, header compression, and other information of this kind. Speech services can be implemented by the broadcast controller. The voice controller provides speech planning, broadcasting and management services. The control message also provides authorized mobile stations with the above-mentioned speech parameters. Before providing the parameters of the speech-the controller of the broadcast can verify that the mobile station was signed on the requested language-lend service.

The communication system 100 may have one or more of the number of broadcast controllers. For example, in one embodiment, the base stations 101 and 160 can use the common control loop 153. The base stations 101 and 160 and the mobile stations within the service area of ​​the base stations 101 and 160 provide a common set of broadcast parameters. According to various aspects of the invention, base stations 101 and 160 transmit identification of the controller. When the mobile station is roaming into the service area of ​​the base station, the mobile station accepts the identification of the controller. Identification of the broadcast controller can be transmitted by the base station periodically or on the basis of a request from the mobile station. In another embodiment, the identification of the controller may be included in other information, which mobile station usually receives from the base station during its roaming in the service area of ​​the new base station. Different standard interaction options, included here, offer one or more ways to exchange information when roaming a mobile station in a new service area.

In another embodiment, the base station 101 may use a broadcast controller 151 in the communication system 100, and the base station 160 may use a different speech controller 152. Speech settings used broadcast controllers 151 and 152, may be different. Consequently, the identification of the speech controller received from base stations 101 and 160 is not associated with a common set of broadcast parameters. Also, when the mobile station from the base station maintenance outsourcing 101 is roaming to the base station service area 160, the mobile station needs to accept a new set of broadcast parameters associated with the broadcast controller 152.

In block diagram 270 of FIG. 2, there are individual steps that may be performed by a mobile station that performs roaming from the service area of ​​the first base station to the service station of the second base station for efficient reception and change of broadcast parameters for reception of speech services in the communication system 100 according to various aspects of the invention. At block 271, the mobile station, for example, the mobile station 102, which performs roaming from the base station service area 101 to the base station service area 160, has adopted the first identification of the speech controller from the first base station, for example, a base station 101. In step 272, the mobile station receiving - has a second identifier of the broadcast controller for one base station, for example, a base station 160. The first identifier of the broadcast controller may be associated with a speech controller 151, and the second identification of the speech controller may be associated with the speech controller 152. At block 273, the mobile station can determine whether the first and second identities of the broadcast controllers are associated with the general parameters of the statement. In one embodiment, the broadcast control 151 and 152 may use the same parameters. In another embodiment, the first and second identification of the controller may be associated with a common broadcast controller 153 which can be used for some base stations 101 and 160. In this case, at station 274, the mobile station for receiving speech services continues to use the same broadcast parameters. In step 275, if the first and the second of the speech controller identification are not associated with the general broadcasting parameters, the toll station asks for the transmission of a new set of broadcast parameters from the second broadcast controller, for example, the broadcast controller 152. The editing of parameters can be done by a second base station, for example, a base station 160. At block 276, the mobile station receives a new set of broadcast parameters and continues to receive paging services using a new set of broadcast parameters.

FIG. 3 illustrates a block diagram of a transmitter 300 for transmitting forward and reverse link signals. Transmitter 300 can be used to re-edit main channels, control channels, add-on channels and speech channels. Data of the speech channel for transmission is introduced modulation modulator 301 for modulation. The modulation may be carried out in accordance with any of the known known modulation modalities, such as ΩΛΜ, RPC, or VRZK. Before the modulation, the speech-to-channel data for transmitting can take one more number of coding levels. The choice of data modulation speed can be done by the data rate selector 303 and the power level. The choice of data rate can based on feedback information that is taken from the destination, or can be fixed for the speech channel. In case of inverse The speed of the data transfer is very common, among other factors considered, based on the state of the channel. The transfer speed selector 303

data and power level accordingly selects the data transmission speed in the modulator 301. Output data of the modulator 301 pass through the signal expansion operation and in the block 302 amplify for transmission from the antenna 304. The data rate selector 303 and the power level also performs a selection level of power for the level of amplification of the transmitted signal. A combination of selected speed data transmission and power level provides the possibility of appropriate decoding of transmitted data at the receiving destination. Also, a pilot signal is formed in block 307. In block 307, the pilot signalincreases to the corresponding level. The level of power of the pilot may correspond to the state of the channels to the receiving destination. The pilot signal may be coupled to the channel signal in the combiner 308. The connected signal may be amplified in the amplifier-receiver 309 and transmitted from the antenna 304. The antenna 304 can be implemented in any combination, including antenna arrays and configurations of many inputs and a plurality of outputs. Selected modulation, data rate and encoding method for transmitting data of the speech channel can match the broadcast parameters set by the broadcast controller. For example, if the base station 101, which includes the transmitter 300, transmits the speech channel, and the broadcast controller 151 controls the transmitted information, broadcast parameters 151 are used in the transmission channel 300 for transmitting the speech channel. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. including antenna arrays and configurations from a multitude of inputs and a multitude of outputs. Selected modulation, data rate and encoding method for transmitting data of the speech channel can match the broadcast parameters set by the broadcast controller. For example, if the base station 101, which includes the transmitter 300, transmits the speech channel, and the broadcast controller 151 controls the transmitted information, broadcast parameters 151 are used in the transmission channel 300 for transmitting the speech channel. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. including antenna arrays and configurations from a multitude of inputs and a multitude of outputs.

For example, if the base station 101, which includes the transmitter 300, transmits the speech channel, and the broadcast controller 151 controls the transmitted information, broadcast parameters 151 are used in the transmission channel 300 for transmitting the speech channel. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. the speed of data transmission and the coding method for transmission of the data channel of the broadcast channel can respond to the broadcast parameters set by the broadcast controller. For example, if the base station 101, which includes the transmitter 300, transmits the speech channel, and the broadcast controller 151 controls the transmitted information, broadcast parameters 151 are used in the transmission channel 300 for transmitting the speech channel. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. the speed of data transmission and the coding method for transmission of the data channel of the broadcast channel can respond to the broadcast parameters set by the broadcast controller.

Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. then broadcast parameters of the broadcast controller 151 are used to transmit the broadcast channel 300. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding. then broadcast parameters of the broadcast controller 151 are used to transmit the broadcast channel 300. Consequently, three of the speech parameters that must be transmitted to the mobile station in the set of speech parameters can be selectable-no modulation, data rate, and method of coding.

FIG. 4 illustrates a block diagram of a receiver 200 that is used to process and demodulate an accepted SUMM signal when functioning in accordance with various aspects of the invention. The receiver 200 may be used to decode the information in the signals of the forward and backward communication lines. The receiver 200 can be used to decode information in the main channel, channel identification, additional channels and speech channels. Accepted (RX) samples can be stored in RAM (OZP) 204. Accepted samples are generated by radio frequency / intermediate frequency system 290 (RF) / IG (IF) and antenna system 292. System290 PIRIIR and antenna system 292 may include one or more components for reception of several signals and PPAR processing of the received signals to use the benefits of winning an enlarged reception. Several received signals Distributed on different trajectories, may be signals from a common source. The antenna system 292 receives RR signals and transmits RR signals to the PP / IP system 290. The 290RP / IR system can be any conventional PP / IP receiver. Accepted RR signals are filtered, converted with a decrease in frequency and digitized to form PX samples at frequencies of the main band of frequencies. The samples are supplied to the multiplex (s) 252. Output data of those 252 are fed to the search terminal 206 and the output elements 208. A control system 210 is connected to them.

connects the decoder 214 to the output elements 208. The control system 210 may be a microprocessor controlled by the software and may be located on the same integrated circuit or on a separate integrated circuit. The decoding function in the decoder 214 can be implemented in accordance with a turbo decoder or any other suitable decoding algorithm. A signal transmitted from a source can be encoded with several levels of codes. Also, the decoder 214 decodes the received samples according to the following codes. The decoder 214 may perform a decoding function according to the encoding information received in the broadcast parameters.

During the action taken, the samples are submitted to those252. Mich 252 submits samples to the search block 206 and selects the 208 outputs. The control unit 210 configures the output elements 208 for executing demo-duplication and the operation of the reverse expansion (compression) relative to the received signal at different time drives based on the results from the search block 206. The demodulation results are merged 212i and transmitted to the decoder 214.

This way, basically, is known. The receiver 200 may be used in a portion of the receiver of base stations 101 and 160 to handle received feedback signals from a mobile station and in the receiver part of any of the mobile stations for processing received received forward link signals.

FIG. 5 depicts a general circuitry of a transmitter system 500 that includes a receiver 200 and a transmitter 300 to support a communication link with the address, including reception of speech channels. The receiver transmitter 500 may be embedded in a mobile station or a base station. With receiver-200 and transmitter 300 can be connectedprocessor 401 for processing data transmitted and received. Different aspects of the receiver 200 and the transmitter 300 may be common, although the receiver 200 and the transmitter 300 are depicted separately. According to one aspect, the receiver 200 and the transmitter 300 may share a common heterodyne and a common antenna system for receiving and transmitting the RSFF. The transmitter 300 receives data for the transmission to the input 405. The data processing unit 403 prepares the data for transmission on the transmission channel. If the transmission channel is a speech channel, the data processing is carried out in accordance with the broadcast parameters used by the receiving and transmitter 500. The received data after decoding in the decoder 214 is received at the input 404 of the processor 401. Accepted data is processed by the processing unit 402 of the received data in the processor401. If the received channel is a speech-to-speech channel, the processing of received data, which is re-

are given, carried out in accordance with the parametersword, used by the transmitter for the transmission of the speech channel. Different operations of the processor-ra 401 can be combined into one or several processing blocks. Receiver-transmitter 500 may be connected to another device. Receiver-transmitter 500 can be an integral part ofdevice. The device may be a computer or device that acts like a computer. The device can be connected to a data network, such as the Internet. In the case of the implementation of the transmitter receiver 500 into the base station, the base station can connect through several connections to the network, such as the Internet.

The processing of received data, basically, involves checking for errors in accepted packets of data. For example, if the received data packet has an unacceptable level error, the processing unit 402 receives the received data transfer instruction 403 to generate a request for retransmission of the data packet. Request transmitted on the transmission channel. However, for the language channel, the receiver's action may not include a retransmission request. The speech service may include the transmission of a video signal to a CB station and the reproduction of this video in a mobile station. Data on the voice channel may be transmitted in the data block at a time. In the interest of the receiver data storage unit 480, the data received in each data frame can be copied to restore the data block to play the voice signal of the speech services in the mobile station.

A broadcast controller, such as any of the co-controllers of broadcasting 151, 152, and 153, can control the broadcasts of a large number of base stations in the communication system. A set of base stations can form a subnet of the basic state-of-these. The base station may transmit the subnet ID to the mobile stations. The subnet identifier identifies the subnet. All base stations in the subnet can be served by one broadcast controller. The identification of the subnet that is transmitted from each base station in the subregion may indicate the affiliation with the general subnet in accordance with various aspects of the invention. In essence, when the mobile station performs roaming between the subnet base stations, the mobile station uses the same speech parameters for speech services. According to various aspects of the invention, the mobile station determines at step 273, according to FIG. 2, whether the first and second base stations belong to a common subnet, having a general broadcasting contender, and, therefore, a general identification of the broadcast controller and general broadcasting parameters. In fact, when the first and second base stations belong to a common subnet, the mobile station uses the same broadcasting parameters for the services. When the first and second base stations belong to different subnets, at stage 275 and 276, the mobile station may request and accept a new set of broadcast parameters.

In addition, in another possible embodiment,

The general broadcasting controller may

Managing multiple subnets. According to

6 depicts the possible configuration of 600 sub-networks of the communication system. The speech controller 610 can control speech stations of all of the base stations in the subnet 601 and subnet 602. The broadcast controller 620 can perform speech control services for all base stations in the subnet 603. In essence, when the mobile station determines that the base station to live on other subnets, then the mobile station and / orbase station determines whether the mobile station needs a new set of broadcast parameters. Communication to determine if a new set of broadcast parameters is needed can be accomplished through the assistance of several messages. For example, the base station can determine whether the subnet of the previous base station is serviced and the current base station is submerged by one control loop. The base station can perform this function, supporting the list of other subnets that are served by the broadcast controller that serves this base station. In another embodiment, the base station or the speech controller transmits the mobile station a list of subnets operated by the general broadcast controller. The message may also be identifiers for the identification of the base stations, the members of each subnet. The specified subnet list may be transmitted to the mobile station in conjunction with the subscription parameters. When the mobile station is within the service area of ​​the base station belonging to another subnet, the mobile station verifies whether a new subnet is included in the sub-list of the current broadcast controller. If so, the mobile station continues to use the current parameters speech Otherwise the mobile station asks for a new set of parameters from the new broadcast controller. Since the subnets may be very large, the broadcast controller can provide the mobile status only as a partial list of subnets controlled by the broadcast controller. This list can be updated when moving the mobile station to the subnetting range included in the current list. In another variant of the implementation information can be encoded by pointing out a series of successive subnets identifiers. Consequently, the message can identify the first and last sub-ge (or base station identifiers) from identities of a series of successive subnets (or base stations). In another embodiment, the base stations located within the service area may transmit a message indicating the need for a new set of speech parameters, since the mobile station may enter the zone of the base station service on the subnet, controlled by another broadcast controller. In this case, when the mobile station roaming the first subset of the first subnet controlled by the first broadcast controller, to another base station of the second subnet, controlled by the second broadcast controller, the mobile station transmits the request for a second time to the base station for transmitting the modem parameters, associated with the second speech controller.

The speech channel can transmit cipher-

the data to prevent the use of speech-free services by unauthorized users. A user identification block 499 (BIP, iM), shown in FIG. 5, may contain individual user information that includes a key encryption. Various embodiments of the cipher communication are described in detail in two patent applications registered with designated registration numbers 09 / 933.972 and 10 / 233,188, which are named: MIiOiApis LerraGiiiTog Zeshiyuu ipUuAia RgosseyipD Zuyyet, transferred to the right-hand column of the given applications, and the content of which is fully incorporated herein by reference. iiM 499 is associated with a certain user and the pre-7 is used to verify that the mobile station that contains the receiver-transmitter 500 is entitled to for example, provided to the user, such as access to the mobile telephone network. So, with iiM 499 faster associated user than mobile station. One user can be associated with several IM 499.

A speech service encounters a problem in determining how to distribute keys to subscribed users. To decode the content that is transmitted at a specified time, the mobile station should have information about the current decryption key that is valid on the current subnet. To avoid theft of the service, the key decryption must occur frequently, for example, every minute. The specified decryption keys are called short-term keys (QC, QC). KK is used to decode the contents of the one that is transmitted over a short period of time. The key is output from the Access Key to the Language, which can be stored in the IM. A list of subnets controlled by the broadcast controller can be stored in the IM group together with the Access Language Key. A mobile station may need to receive from the broadcast controller the Access Key to the Enrollment in the set of broadcast parameters. ii Accepts the ID for the current subnetwork together with the request for calculating KK. iiM can verify whether a Live Access Key is active on the current subnet. If the Access Key is not valid on the current subnet, then i can send an indication of the initiation process for obtaining a new key from the new broadcast controller to continue receiving the language services.
