Method and apparatus for supporting RLF reason detection or handover failure reason detection

摘要

A method and apparatus for supporting Radio Link Failure (RLF) reason detection or handover failure reason detection are provided. The method includes detecting the Mobility Robustness Optimization (MRO) problems without RLF reporting in a 3rd Generation (3G) or a 2nd Generation (2G) mobile communication system, the impact on a 3G or a 2G mobile communication system is reduced, and then correct self-optimization is performed to improve the performance of the mobile communication system.

主权项

1. A method for communicating, the method comprising:
acquiring, by a first base station, an identifier of a UE accessing a first cell of the first base station; storing, by the first base station, UE context information of the UE after a handover of the UE to a second cell of a second base station, and storing a cell identifier of the second cell; receiving, by the first base station, a radio resource control (RRC) connection request message after a radio link failure between the UE and the second cell occurs, the RRC connection request message including an identifier of the UE and information indication whether a reason for an establishment of a RRC connection is due to a circuit switched fallback (CSFB); searching, by the first base station, a UE context based on the identifier of the UE in the RRC connection request message; and detecting, by the first base station, a reason for the failure based on the UE context, if the reason is not due to the CSFB.
