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. The present invention will achieve dynamic sharing of Abis transmission resources on a RTS layer so as to optimize using of Abis transmission resources, reduce waste and decrease operating cost.
