  • Method and apparatus for optimized assignment of Abis transmission resources based on dynamic statistical time division multiplexing
    Patent number: 7818019
    Abstract: The present invention relates to technique for optimized assignment of Abis transmission resources based on dynamic statistical time division multiplexing, the method comprising the steps of: assigning a set of 64 k TS's to GPRS/EGPRS services on an Abis link, the set of 64 k TS's shared among all BTS's connected to the Abis interface; a PCU assigning sufficient Abis transmission resources to a TRX based on the load thereof if the TRX has EGPRS services; a BSC interconnecting Abis transmission resources and BSC-PCU transmission resources and informing a BTS that said Abis transmission resources have been assigned to a TRE mapped to the TRX; the PCU reassigning bandwidth of the Abis transmission resources based on changes in the load of the TRX; in each TRX, all RTS's statistical-time-division-multiplexing all transmission resources of the TRX based on flow in different periods for different RTS's.

  • Method and apparatus for implementing voice group call service and data group call service by circuit switch or packet switch respectively in mobile network
    Publication number: 20060221890
    Abstract: The present invention provides a method and corresponding apparatus for multimedia group call service in mobile network. According to the present invention, voice group call is established by circuit switch while data group call is established by packet switch. Compared with the prior art, the solutions disclosed in the present invention can shorten the “Call Setup latency” and “Intra-call latency” when performing voice group call and can provide better link quality.
