发明名称 METHOD AND SYSTEM FOR HANDLING HANDOFF FAILURES TO CLOSED SUBSCRIBER GROUP CELL
摘要 <p>A method and a system for handling handoff failures to a Closed Subscriber Group (CSG) cell are provided, which are used to solve the technical problem of interface signaling consumption and network performance degradation caused by the handoff of a User Equipment (UE) to a non-member CSG cell. When UE is not an authorized user of the target CSG cell, the Core Network informs the source base station of the non-member failure message, and forces UE to update the allowed CSG list to prevent the source base station or source Radio Network Controller (RNC) or source home base station from sending a handoff request to the same target cell, or prevents UE from sending handoff request to the same target cell frequently by setting a delay timer, or the source base station or source RNC or source home base station prevents UE from handing off to a neighboring CSG cell with the same CSG identification (ID) under the condition of being able to acquire the CSG ID of the target CSG cell. The method and the system can prevent sending the handoff request to the same target CSG cell again after the handoff failure of UE, thereby decreasing the signal consuming between the interfaces and enhancing the performance of the network.</p>
