The present invention relates generally to the field of communications, and more particularly, to communications of broadcast services in a communication system.
In a wireless communication system, unnecessary and excessive transmissions by a user may cause interference for other users in addition to reducing the system capacity. The unnecessary and excessive transmission may be caused by requesting transmission of unnecessary data in the communication system. A system for broadcast application may require use of specific broadcast parameters. At a time before receiving the broadcast services, a mobile station may request transmission of such broadcast parameters from a serving base station. Such broadcast parameters may include the broadcast modulation format information, data rate information, encryption key information, coding information, broadcast channel frequency information and other similar type information. Several base stations may be controlled by a common broadcast controller. Therefore, as long as the mobile station is within the coverage areas of these base stations, the mobile station does not need to request retransmission of the broadcast parameters. However, the mobile station may not have a reliable way of determining whether a new base station uses the same or different broadcast controller when the mobile station moves to the coverage area of the new base station. As such, the mobile station may request transmission of broadcast parameters every time it moves to the coverage area of a new base station. Requesting and receiving the transmission of the broadcast parameters may interrupt the broadcast services played at the mobile station, and cause unnecessary and excessive transmissions in the communication system.
Therefore, there is a need for a method, apparatus and system for updating a mobile station broadcast parameters for broadcast services in a communication system.
A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services.
The features, objects, and advantages of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings in which like reference characters identify correspondingly throughout and wherein:
Generally stated, a novel and improved system, method and apparatus provide for efficient use of communication resources for broadcast services in a communication system. A set of broadcast parameters is associated with one or more broadcast controllers in accordance with various aspects of the invention. While using a first broadcast controller through a first base station, obtaining a second broadcast controller identification from a second base station triggers a process for determining whether the first and second broadcast controller identifications are associated with a common set of broadcast parameters. Requesting transmission of a new set of broadcast parameters is triggered when the first and second broadcast controller identifications are not associated with a common set of broadcast parameters in accordance with various aspects of the invention. One or more exemplary embodiments described herein are set forth in the context of a digital wireless data communication system. While use within this context is advantageous, different embodiments of the invention may be incorporated in different environments or configurations. In general, the various systems described herein may be formed using software-controlled processors, integrated circuits, or discrete logic. The data, instructions, commands, information, signals, symbols, and chips that may be referenced throughout the application are advantageously represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or a combination thereof. In addition, the blocks shown in each block diagram may represent hardware or method steps.
More specifically, various embodiments of the invention may be incorporated in a wireless communication system operating in accordance with the code division multiple access (CDMA) technique which has been disclosed and described in various standards published by the Telecommunication Industry Association (TIA) and other standards organizations. Such standards include the TIA/EIA-95 standard, TIA/EIA-IS-2000 standard, IMT-2000 standard, UMTS and WCDMA standard, all incorporated by reference herein. A system for communication of data is also detailed in the “TIA/EIA/IS-856 cdma2000 High Rate Packet Data Air Interface Specification,” incorporated by reference herein. A copy of the standards may be obtained by accessing the world wide web at the address: http://www.3gpp2.org, or by writing to TIA, Standards and Technology Department, 2500 Wilson Boulevard, Arlington, Va. 22201, United States of America.

Base station 101 communicates with each mobile station that is in its coverage area via a forward link signal transmitted from base station 101. The forward link signals targeted for mobile stations 102-104 may be summed to form a forward link signal 106. The forward link may carry a number of different forward link channels. Each of the mobile stations 102-104 receiving forward link signal 106 decodes the forward link signal 106 to extract the information that is targeted for its user. Base station 160 may also communicate with the mobile stations that are in its coverage area via a forward link signal transmitted from base station 160. Mobile stations 102-104 communicate with base stations 101 and 160 via corresponding reverse links. Each reverse link is maintained by a reverse link signal, such as reverse link signals 107-109 for respectively mobile stations 102-104. The reverse link signals 107-109, although may be targeted for one base station, may be received at other base stations.
Base stations 101 and 160 may be simultaneously communicating to a common mobile station. For example, mobile station 102 may be in close proximity of base stations 101 and 160, which can maintain communications with both base stations 101 and 160. On the forward link, base station 101 transmits on forward link signal 106, and base station 160 on the forward link signal 161. On the reverse link, mobile station 102 transmits on reverse link signal 107 to be received by both base stations 101 and 160. For transmitting a packet of data to mobile station 102, one of the base stations 101 and 160 may be selected to transmit the packet of data to mobile station 102. On the reverse link, both base stations 101 and 160 may attempt to decode the traffic data transmission from the mobile station 102. The data rate and power level of the reverse and forward links may be maintained in accordance with the channel condition between the base station and the mobile station.
The communication system 100 may also provide broadcast services to the mobile stations. Broadcast services may include receiving video or audio broadcast through base stations 101 and 160. In another example, the weather or traffic information may be broadcasted for the mobile stations. In a broadcast system, the same signal may be sent simultaneously to a large number of mobile stations. The broadcast signal may be encrypted. Therefore, the mobile stations may need to sign up for such services. The mobile station may need to obtain encryption information from the base station, before receiving the services. In addition, the mobile station may need to receive other broadcast parameters in order to receive the broadcast services. The broadcast parameters may include the broadcast channel identifier, broadcast modulation format information, data rate information, encryption key information, coding information, broadcast channel frequency information, encryption and decryption keys information, header compression information, and other similar type information. The broadcast services may be controlled by a broadcast controller. The broadcast controller provides the broadcast programming, transmission and control of the broadcast services. The broadcast controller also provides the aforementioned broadcast parameters to the authorized mobile stations. The broadcast controller may verify that the mobile station has signed up for the requested broadcast service before providing the broadcast parameters.
The communication system 100 may have one or more broadcast controllers. For example, in one embodiment, the base stations 101 and 160 may use a common broadcast controller 153. A common set of broadcast parameters is provided to base stations 101 and 160, and to the mobile stations within the coverage area of base stations 101 and 160. In accordance with various aspects of the invention, the base stations 101 and 160 transmit a broadcast controller identification. When a mobile station roams into the coverage area of a base station, the mobile station receives the broadcast controller identification. The broadcast controller identification may be transmitted by the base station periodically or transmitted based on a request by a mobile station. In another embodiment, the broadcast controller identification may be included with other information that a mobile station normally acquires from a base station when it roams into the coverage area of the new base station. Various interoperability standards, incorporated herein, provide one or more methods for exchange of information when a mobile station roams into a new coverage area.
In another embodiment, in communication system 100, the base station 101 may use broadcast controller 151, and the base station 160 may use a different broadcast controller 152. The broadcast parameters used by the broadcast controllers 151 and 152 may be different. The broadcast controller identifications received from base stations 101 and 160, therefore, are not associated with a common set of broadcast parameters. As such, when a mobile station roams into the coverage area of base station 160 from coverage area of base station 101, the mobile station needs to receive a new set of broadcast parameters associated with the broadcast controller 1152.
Referring to
During operation, received samples are supplied to mux 252. Mux 252 supplies the samples to searcher unit 206 and finger elements 208. Control unit 210 configures finger elements 208 to perform demodulation and despreading of the received signal at different time offsets based on search results from searcher unit 206. The results of the demodulation are combined and passed to decoder 214. The demodulation function may be performed in accordance with the modulation information received in the broadcast parameters. Decoder 214 decodes the data and outputs the decoded data. Despreading of the channels is performed by multiplying the received samples with the complex conjugate of the PN sequence and assigned Walsh function at a single timing hypothesis and digitally filtering the resulting samples, often with an integrate and dump accumulator circuit (not shown). Such a technique is commonly known in the art. Receiver 200 may be used in a receiver portion of base stations 101 and 160 for processing the received reverse link signals from the mobile stations, and in a receiver portion of any of the mobile stations for processing the received forward link signals.
The processing of the received data generally includes checking for error in the received packets of data. For example, if a received packet of data has error at an unacceptable level, the received data processing block 402 sends an instruction to transmit data processing block 403 for making a request for retransmission of the packet of data. The request is transmitted on a transmit channel. However, for the broadcast channel, the receiver operation may not include a request for retransmission. The broadcast service may include sending video from the base station and playing the same video at the mobile station. The broadcast channel data may be transmitted in a block of data at a time. As such, the receive data storage block 480 may accumulate data received in each frame of data to reconstruct the block of data for the playing the video of the broadcast services at the mobile station.
A broadcast controller, such as any of the broadcast controllers 151, 152 and 153, may control broadcast services of a large number of base stations in a communication system. A set of base stations may form a subnet of base stations. The base station may transmit a subnet identifier to the mobile stations. The subnet identifier identifies the subnet. All base stations in a subnet may be served by the same broadcast controller. The subnet identification sent from each base station in a subnet may indicate that they belong to a common subnet in accordance with various aspects of the invention. As such, when the mobile station is roaming among the base stations of a subnet, the mobile station uses the same broadcast parameters for broadcast services. In accordance with various aspects of the invention, the mobile station determines, while referring to
Moreover, several subnets may be controlled by a common broadcast controller, in another exemplary embodiment. Referring to
The broadcast channel may transmit encrypted data to prevent unauthorized users from using the broadcast services. A user identity module (UIM) 499 shown in
The broadcast service faces a problem in determining how to distribute keys to subscribed users. To decrypt the broadcast content at a particular time, the mobile station must know the current decryption key that is valid in the current subnet. To avoid theft-of-service, the decryption key should be changed frequently, for example, every minute. These decryption keys are called Short-term Keys (SK). The SK is used to decrypt the broadcast content for a short-amount of time. The SK is derived from a Broadcast Access Key that may be stored in the UIM. The list of subnets controlled by a broadcast controller may be stored in the UIM along with the Broadcast Access Key. The mobile station may need to obtain the Broadcast Access Key from the broadcast controller in the set of broadcast parameters. The UIM receives an identifier for the current subnet along with a request to compute the SK. The UIM may check if the Broadcast Access Key is valid in the current subnet. If the Broadcast Access Key is not valid in the current subnet, the UIM may send an indication to initiate a process to obtain a new key from the new broadcast controller to continue the reception of broadcast services.
