The level of technology

Early network multiple access code division multiplexing (CDMA, mdcr), such as the network, IS-95, is allowed to transmit only a small amount of data traffic. However, wireless networks of the third generation, such as IS-2000 (also known as CDMA2000), structurally allow you to pass a much larger load when transferring data. The network IS-2000 can effectively provide high-speed data services and voice traffic. Other networks, such as network 1xEV-DO is designed mainly for data transmission. The network of these types, if they are simultaneously used for both voice and data, typically transmit voice channel adjacent to the channel for data transmission. However, the network IS-2000 (edition C CDMA2000) transmit voice and data over a single channel.

USGP (BCMCS service broadcast multicast) represents one of the new types of data services that providers wireless embody in wireless networks of the third generation, including network IS-2000. It is expected that USGP will become a very important service in the next edition of wireless communication standards. For group broadcast data is the same data content (e.g., sporting event, weather, news, etc.) passed in the armed forces is (or, at least, many) of wireless terminals (or mobile stations) in the service area of a base station of a wireless network. USGP allows you to optimize the use of the radio interface IS-2000 data USGP one or more mobile stations in one or more regions of the network operator.

The user can use the services USGP provided by the serving network, in various ways, including receiving information on a service channel (for example, using SPSU (BSPM) - message service parameters broadcast from the network. The network operator can control each group of data, taking into account the need charging, the regions of the network where the multicast data is available for different users, and encryption for group data transfer to protect against unauthorized reception.

However, in modern system designs USGP, if the quality of the multicast data received specific mobile station (MS, MS), the bad, there is no technology that would allow a mobile station (MS) disable offer or provide services or to abandon them. For example, the reason for the refusal of service may be inappropriate admission or interruptions in the provision of continuous services. If network operators to notify about such problem is with the quality of service (QoS, QoS), network operators can use this information to the appropriate network configuration. Modern system design USGP not allow network operators to provide feedback on request from users because of the nature of these services.

Thus, in the art there is a need for improved systems and methods of deployment USGP in a wireless network. In particular, there is a need for a feedback mechanism to ensure QoS. In addition, there is a need for technology that would allow MS to disable USGP or to abandon it.

Detailed description of the invention

Next will be described the preferred options issue the log of the present invention. In the following description, a detailed description of known functions and configurations used here, is not listed if their description will complicate the understanding of the subject of the present invention.

Described below Fig.1-7 and different ways to perform that is used to describe the principles of the present invention in this patent document is presented only as an illustration and should not be construed as any limitation of the scope of the invention. For specialists in the art will understand that the principles of the present invention can be performed using any suitably arranged wireless network.

Figure 1 presents an exemplary wireless network 100, which effectively deployed broadcast multicast services (USGP) in accordance with the principles of the present invention. Wireless network 100 includes multiple cells 121-123, each of which contains one of the base stations BS BS 101, BS 102, or BS 103. Base stations 101-103 communicates with multiple mobile stations (MS) 111-114 using channels multiple access code division multiple access (CDMA) standard IS-2000-C (that is, the Edition C cdma2000). Mobile stations 111-114 may be any appropriate wireless devices, including conventional cellular glad telephony, handset PCS (SPC, standard for personal video conferencing, personal handheld computers, portable computers, telemetry devices, etc. that allow you to perform communication with the base stations via wireless communication channels.

The present invention is not limited to mobile devices. You can use the wireless access terminal of other types, including fixed wireless terminals. For simplicity, below and described only the mobile station. However, it should be understood that the use of the term "mobile station" in the following claims and in the description is intended to cover as a truly mobile devices (e.g. cell phones, wireless laptops), and fixed wireless terminals (e.g., monitoring devices capable of transmitting data wirelessly.

Dashed lines represent approximate boundary between cells 121-123, which are base stations 101-103. The cell is shown to be roughly circular for illustrative purposes and only for clarification. It should clearly be understood that the cells may have other irregular shapes, depending on the selected configuration of the cell and natural and artificial obstacles.

As is well known the in the art, cell 121-123 consist of a variety of sectors (not shown), in which the directional antenna is connected to the base station, irradiates each sector. An embodiment shown in figure 1, illustrates a base station in the cell center. In alternative embodiments, directional antennas are located at the corners of the sectors. The system in accordance with the present invention is not limited to any particular configuration of cells.

In one embodiment, the present invention BS 101, BS 102 and BS 103 contain the controller (ASC, BSC) base station and at least one subsystem base transceiver (bbs, BTS). The controller base station subsystem base transceiver is well known to specialists in this field of technology. The base station controller is a device that manages resources of a wireless communications channel, including subsystem base transceiver, for specified cells within a wireless communication network. Subsystem base transceiver includes an RF (RF) transceivers, antennas, and other electrical equipment located in each cell. This equipment may include units air conditioning units heating, electrical power, telephone line interfaces and RF transmitters and RF receivers. For prototye clear explanation of the operation of the present invention subsystem base transceiver each cell 121, 122 and 123 and the base station controller associated with each subsystem base transceiver, in General, represented as BS 101, BS 102 and BS 103, respectively.

BS 101, BS 102 and BS 103 transmits voice signals and data signals between itself and the public switched telephone network (PSTN) (TXOP, PSTN) (not shown) through line 131 of communication and center 140 switching for mobile communications (SMC, MSC). BS 101, BS 102 and BS 103 also transmits data signals, such as packet data to the Internet (not shown) through line 131 communication and node 150 server packet data (USPD, PDSN). The module 190 functions package management (state, PCF) controls the flow of data packets between base stations 101-103 and RTU 150. The module 190 state can be performed as part of the USPD 150, as part of the base stations 101-103 or as a separate device that is connected to RTU 150, as shown in figure 1. Line 131 also provides a communication channel for transmission of control signals between the SMC 140 and BS 101, BS 102 and BS 103 that is used to establish connections for the circuits of voice and data between SMC 140 and BS 101, BS 102 and BS 103.

Line 131 may represent any appropriate means of communication, including a T1 line, a T3 line, a fiber optic communication channel or connection to transfer data of any other type. Connection line 131 allow to transmit analog voice signals is whether the digital voice signals in the format of pulse-code modulation (PCM, PCM) format, Internet Protocol (PI, IP), in the format of an asynchronous transfer mode (ARP, ATM) data or the like. In accordance with the preferred implementation of the present invention, line 131 also provides connectivity over Internet Protocol (PI), which transmit data packets between base stations of the wireless network 100, including BS 101, BS 102 and BS 103. Thus, line 131 includes a local area network (LAN LAN), which provides a direct connection Protocol PI between base stations without using RTU 150.

SMC 140 is a switching device that provides services and coordination between the subscribers in a wireless network and external networks such as TXOP or the Internet. SMC 140 are well known to specialists in this field of technology. In some embodiments, execution of the present invention, the line 131 may be a few different data channels, each data channel connects one of the BS 101, BS 102, or BS 103 with SMC 140.

In the embodiment, the wireless network 100 shown in figure 1, MS 111 and MS 112 are located in the cell 121 and communicates with the BS 101. MS 113 is located in cell 122 and performs data exchange with the BS 102 and MS 114 is located within the cell 123, and performs data exchange with the BS 103. MS 112 located near the e to the boundary of the cell 123 and moves in the direction of the cell 123, as shown by the arrow located next to the MS 112. At some point, when MS 112 moves to the cell 123 and out of the cell 121, is transmitted to the subscriber.

As is well known to specialists in this field of technology, during the procedure of transfer of the subscriber is transmitted to the call control from the first cell to the second cell. The transfer of the subscriber can be either "soft" transfer of the subscriber or "hard" transmission of the subscriber. During soft handover of the subscriber connection is established between the mobile station and the base station in the second cell until an existing connection is lost between the mobile station and the base station in the first cell. When hard the transmission of the subscriber an existing connection between the mobile station and the base station in the first cell break before you installed the new connection between the mobile station and the base station in the second cell.

As MS 112 moves from cell 121 in cell 123, MS 112 detects a pilot signal from the BS 103 and transmits the message to the measurement level of the pilot signal in the BS 101. When the level of the pilot signal transmitted in the BS 103 and received MS 112, which then transmits the report signal level exceeds the threshold value, the BS 101 initializes the process of soft transmission of the subscriber, transmitting to the target BS 103 signal is then required to complete the transfer of the subscriber, as described in the TIA/EIA IS-95, TIA/EIA IS-2000 or IS-856 (CDMA2000 family of standards).

BS 103 and MS 112 continue to negotiate the establishment of a data channel in the CDMA channel. After establishing a data transmission channel between BS 103 and MS 112 MS 112 communicates with the BS 101 and BS 103 in the soft mode of transmission of the subscriber. For specialists in the art will understand that a soft handover of the subscriber improves the characteristics of both direct (from BS to MS) channel, and the reverse (from MS to BS) data channel. When the signal level of BS 101 falls below the specified threshold level signal MS 112 may lose the connection with the BS 101 and can receive signals only from BS 103. As a result, the call is transferred without interruption from BS 101 BS 103. The above described soft handover of the subscriber assumes that the mobile station is a voice call or a call for data. Inactive transmission of the subscriber is the transfer of a subscriber between cells for the mobile station, which performs data transmission over the control channel or the paging channel.

In accordance with the principles of the present invention a mobile station operating in the wireless network 100 can receive the transmission group data for broadcast transmission over the shared transmission channel traffic is. For example, in an embodiment a is-2000, each of the BS 101-103 can transmit and each of MS 111-114 capable of receiving the group of data on the direct channel packet data (F-PDCH), or by a direct auxiliary channel (F-SCH), or both channels.

Figure 2 presents an example of group data from multiple base transceivers (BPS, BTSs) 1-6 in many mobile stations in wireless network 100 in accordance with one implementation of the present invention. The base station is shown in greater detail here. The base station 101 includes six subsystems of the base transceivers designated as BTS1, BTS2, BTS3, BTS4, BTS5 and BTS6. Cell 121 of the base station 101 are shown as hexagonal in shape (and not in the form of a circle, as in figure 1) to illustrate and only for clarification. In each subsystem base transceiver (BPS) using a three-sector antenna, where each of the three sectors (sector αsector βsector γ) covers an arc of 120 degrees. The service area of each BPS is shown as a triangle. Six triangles form a hexagonal coverage area of the base station 101.

Figure 2 presents three exemplary flow group data (transmission) for broadcast transmission. In one sector BTS2 broadcasts the first group of data in mobile stantsii and 202. In one of the sectors BTS1 also performs broadcast transmission of the same group of data in the mobile station 201 and 202. In two different sectors BTS1 performs broadcast transmission of the first group of data in the mobile station 203. Finally, one sector BTS1 and one sector BTS6 transmit the first group data in the mobile station 204.

Two different sector BTS6 transmit to the mobile station 205 and the second group data during the broadcast. One sector BTS6 transmits to mobile station 206 and the second group data in broadcast mode transmission. Finally, one sector BTS5 also broadcasts the second group of data to mobile station 206.

One sector BTS3 transmits in broadcast mode transmission of the third group data in the mobile station 207. Finally, one sector BTS4 also transmits in broadcast mode transmission of the third group data in the mobile station 207.

Because BTS1-BTS6 performs broadcast transmission of the first, second and third group data using a shared channel for transmitting traffic, at least some of the mobile stations No.201-207 accept group data sent by more than one BPS. This improves the ability of the receiving mobile station and is similar transfer operation of the subscriber, when the mobile station is ncia CDMA receives signals direct channel from two or more subsystems of the base transceivers.

Each transmission group data corresponding to a particular service broadcast group data (SPGD, BCMC), the provider of the content, such as CNN, HBO, NBC, etc. Each service has many threads USGP. For example, CNN can provide one thread for visual effect, another thread for sound effects and another thread for captioning. All threads can be passed either by the same bearer traffic, or through different channels of transmission.

Each channel traffic has different characteristics and different resistance to fading. If the user is viewing a particular service SPGD (e.g., provided by HBO) and does not accept the audio component and/or the video component appropriately in accordance with the variants of implementation of the present invention, the user may use the mobile station to transmit the message to the network, informing the network that the audio and/or video portion is taken incorrectly. Based on this information, the network operator can configure the network to optimize audio and/or video components.

Figure 3 shows a block diagram of a wireless mobile station 201 in accordance with the preferred implementation of the present invention. Wireless mobile station 201 includes an antenna 305, the radio is now (RF) transceiver 310, circuit 315 processing the transmit (TX), microphone 320 and the circuit 325 processing reception (RX). MS 201 also contains a speaker 330, the main processor 340, an interface (if, IF) 345 input/output (I/O)interface 350 of the user, the display 355, and a storage device 360. The storage unit 360 further comprises program 361 basic operating system (OS, OS).

Radio frequency (RF) transceiver 310 receives from the antenna 305 incoming group data (RF signal)transmitted in broadcast mode transmission of the base station of the wireless network 100. Radio frequency (RF) transceiver 310 converts with decreasing frequency input signal to obtain a signal of intermediate frequency (if) signal or envelope. The if signal or the signal envelope is passed to the schema 325 processing reception (RX), in which form the processed envelope signal by filtering, decoding and/or digitization of the envelope or the if signal. Circuit 325 processing receiving (RX) transmits the processed envelope signal in the loudspeaker 330 (i.e. in the case of voice data) or in the main processor 340 for further processing (e.g., for browsing).

Circuit 315 processing transmission (TX) receives analog or digital voice data from a microphone 320, or other outgoing data in the form of envelope (e.g., Yes network is nye, e-mail, data, interactive video games) from the main processor 340. Circuit 315 processing transmission (TX) encodes, multiplies and/or digitizes the outgoing data in the form of an envelope for receiving the processed envelope or the if signal. Radio frequency (RF) transceiver 310 receives the outgoing processed envelope signal or the if signal from the circuit 315 processing transmission (TX). Radio frequency (RF) transceiver 310 converts with increasing frequency envelope signal or the if signal to produce a radio frequency (RF) signal, which is passed through the antenna 305.

In a preferred embodiment of the present invention, the main processor 340 is a microprocessor or microcontroller. The storage device 360 is connected with the main processor 340. In accordance with the preferred implementation of the present invention is part of a storage device 360 includes random access memory (RAM) and another part of the storage device 360 includes a flash memory, which acts as a permanent storage device (ROM).

Main processor 340 executes the program 361 basic operating system (OS)stored in the storage device 360 to control the overall operation of a wireless mobile station 201. In one such embodiment, the bases of the second processor 340 controls the reception of signals by the direct channel and the signal transmission on the reverse channel using a radio frequency (RF) transceiver 310, circuit 325 processing receiving (RX) and circuit 315 processing the transmit (TX), in accordance with well known principles.

Main processor 340 may perform other processes and programs resident in memory 360. Main processor 340 can move data to a storage device 360 and in accordance with the requirements of a running process. Main processor 340 is also connected to interface 345 input/output. Interface 345 input/output provides the ability to connect the mobile station 201 with other devices, such as laptops and PDAs. Interface 345 input/output is a data transmission channel between the peripheral device and the main controller 340.

Main processor 340 is also connected to the interface 350 user and block 355 of the display. The user of the mobile station 201 uses the interface 350 user to enter data in the mobile station 201. Display 355 may be a liquid crystal display that allows you to render text and/or, at least, limited graphics, Internet sites. In alternative embodiments, execution can be used to display other types.

For example, if audio and/or video portion of a particular service SPGD is received incorrectly, the user is tel can be accessed through an interface 350 user to the menu, displayed on the display 355, and enter the input user commands containing the property quality of service. For example, the property quality of service can be bad or can represent the absence of receiving audio and/or poor quality video or absence of reception of the video image. In addition, the input user command may optionally contain a designation of the continuation, which indicates whether the user wants to continue receiving specific services SPGD. Main processor 340 converts the input user commands in the format specified transmitting signal messages and transmits this message to the base station via a transceiver 305.

4 shows the block diagram of the structure of the base station 101 in accordance with one implementation of the present invention. The base station 101 includes a controller (ASC) 410 of the base station and base transceiver station (BPS) 420. The base station controllers and base transceiver stations have been described above with reference to figures 1 and 2. ASC 410 manages resources in the cell 121, including 420 BPS. ASC 410 includes a controller 460 USGP. BPS 420 contains the controller 425 BPS, the controller 435 channel (which contains the element 440 representing the channel), interface (if) 445 transceiver, RF block 450 transceiver, antenna lattice 455 and Moni is the PR 355 channel.

The controller 425 BPS contains a processing circuit and a storage device that allows you to execute an operating program that controls the overall operation 420 BPS and provides data exchange with ASC 410. In normal operation, the controller 425 BPS controls the operation of the controller 435 channel, which contains a number of channel elements, including element 440 channel that perform bi-directional data exchange via the direct channel and the backward channel. Direct channel refers to the signals emanating from the base station in the mobile station and the reverse link refers to the incoming signals from the mobile station to the base station. If 445 transceiver transmits signals to the bidirectional channel between the controller 435 channel and RF block 450 transceiver.

Antenna array 455 transmits forward channel signals received from the RF unit 450 transceiver in the mobile station located in a service area of BS 101. Antenna array 455 also passes to block 450 transceiver signals of the backward channel received from the mobile stations located in the service area of BS 101. In a preferred embodiment of the present invention antenna array 455 is a multi-sector antenna, such as a three-sector antenna in which each antenna sector is responsible for transmitting and receiving in a service area with an arc of 12 degrees. In addition, the block 450 transceiver may contain a block of antenna selection to select different antennas in the antenna array 455 as during the transfer operation, and during the receive operation.

For example, in accordance with the variants of implementation of the present invention antenna array 455 allows you to receive a message containing the property quality of service associated with the particular transmission group data from the mobile station and to transmit the message in block 450 transceiver. In turn, the transceiver transmits the message to the controller 425 BPS, which transmits this message in ASC 410. The controller 460 USGP in ASC 410 processes the message to determine whether the mobile station to continue receiving the transmitted group data and the specific characteristics of the quality of service, included in the message. If the mobile station wishes to terminate the service SPGD, the controller 460 USGP updates SMC 140, transmitting notice of termination with the purpose of accrual accounts and tracking.

Property quality of service provides feedback in real time to the controller 460 USGP in relation to the reception quality of a particular service SPGD specific mobile station. Based on the properties of a quality of service controller 460 USGP can optimize the broadcast group Dan who's using BPS 420.

For example, in one embodiment, the controller 460 USGP may request the controller 425 BPS to modify (e.g., increase or decrease) the capacity of the particular thread USGP services SPGD identified in the message transmitted from the mobile station. In another embodiment, if the audio and video multiplexed in one channel traffic controller 460 USGP may request the controller 425 BPS to modify the multiplexing of audio and video signals to improve one or both of them depending on the problems identified by property quality of service.

In an additional embodiment, the controller 460 USGP may transfer property quality service provider of content services SPGD through SMC 140. For example, if the reception of audio and/or video data stream to the controller 460 USGP bad, the controller 460 USGP can send a message about this problem to the content provider and request the content provider to perform the appropriate correction. In yet another embodiment, the controller 460 USGP can add coding error correction (e.g., coding reed-Solomon superimposed on the convolution encoding/turbomotive)that contributes to the proper reception of the mobile station transmission group data. It should be understood that in other variants of the execution controller 460 USGP can be programmed he will report or to optimize problematic transmission group data in other ways.

In one embodiment, the above-described feedback mechanism can be used during network deployment. For example, technical personnel conducting field tests in service BPS 420 may be provided to the mobile station, allowing you to transmit messages about the quality of service in the controller 460 USGP. The network operator can use the information about the quality of service that is transmitted from the mobile stations of the technical staff in the planning of frequencies, installed capacity and channel coding. In another embodiment, the above-described feedback mechanism can be used during the operation of the network. Update the quality of service in real-time allows users to get the best services and provides network operators the ability to provide the best services to the users. Update the quality of service can be provided periodically by the technical staff of the user or in real time during use of the services SPGD users-consumers.

Figure 5 presents the layout of the fields in the message 500 transmitted from the mobile stations to the base station, in the accordance with one implementation of the present invention. The message 500, shown in figure 5, represents the order message, typically used by mobile stations to request a new channel traffic. Message 500 order was modified so that it includes the property quality of service associated with the particular service SPGD. It should be understood that in other versions of the message 500 may be a special message to be generated specifically to provide information about the property quality of service.
