METHOD, SYSTEM AND DEVICE FOR REDUCING USER'S DROP-CALLS DURING THE STATIC DRIFT

摘要

A method for reducing user's drop-calls during the static drift is provided. The method includes that: the drift radio network controller DRNC receives the radio link control RLC sequence number information sent by serving radio network controller SRNC; during the static drift, DRNC uses the RLC sequence number information to process the protocol data unit PDU sequence sent by UE. A system for reducing user's drop-calls during the static drift and a radio network controller RNC are also provided. The disaccord between the RLC sequence number information maintained by UE and the RLC sequence number information maintained by DRNC during the static drift can be solved by the method, system and controller.
