Method, device and system for detecting switching problem

Abstract

The embodiment of the invention discloses a method, a device and a system for detecting a switching problem. The method comprises the following steps that: a reconstructed base station receives a radio resource control (RRC) connection reconstruction request message from user equipment, wherein the RRC connection reconstruction request message carries reconstruction reasons; and the reconstructedbase station determines the corresponding switching problem of an fault base station is switching too late or early according to the reconstruction reasons carried by the RRC connection reconstruction request message, wherein the fault base station refers to the base station of a service cells from which the user equipment receives services before a radio link fails or is switched. In the embodiment of the invention, the specific reconstruction reasons are loaded in the original RRC connection reconstruction request message, and the switching problem of the fault base station is determined according to the reconstruction reasons, the information interaction between base stations is reduced, the interface resources between base stations are saved and the system performance is enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for detecting handover problems. Background technique [0002] In a mobile communication network, in order to improve the utilization rate of spectrum resources and the capacity of the whole system, the radio frequency power of the base station is usually limited to the serving cell. Due to the influence of unavoidable obstacles and shielding objects in the real network, the signal quality of the serving cell where the user equipment is located will continue to deteriorate within a certain period of time. If the signal quality of the serving cell cannot improve within a certain period of time, it will Eventually, the user drops the call. [0003] In order to reduce user call drop due to various reasons, the network side may handover the user equipment from a serving cell with degraded signal quality to a non-serving cell with bett...

Problems solved by technology

When RLF is caused due to inappropriate cell handover parameters, more UEs will experience RRC connection re-establishment events, and a large number of RLF reports will be sent between the re-established base station and the base station where RLF occurred, which will occupy the X2 interface resources between base stations. The X2 interface also needs to be used for various functions such as normal switching, data forwarding, inter-cell interference coordination, and load balancing. A large number of RLF report messages will reduce the efficiency of the X2 interface, which is not conducive to the improvement of system performance.
