Method and apparatus for optimized assignment of abis transmission recources based on dynamic statistical time division multiplexing

摘要

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 64k TS's to GPRS/EGPRS services on an Abis link, the set of 64k TS's shared among all BTS's connected to the Abis interface; a PCU assigning 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 Transceiver Equipment 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. The present invention will achieve dynamic sharing of Abis transmission resources on a RTS layer so as to optimize using of Abis transmission reources, reduce waste and decrease operating cost.
