Method, base station and system for detecting premature handover

Abstract

The embodiment of the invention relates to a method, a base station and a system for detecting premature handover. The method comprises the following steps of: acquiring handover event information of user equipment, wherein the handover event information comprises a cell identifier, a UE identifier and radio link failure (RLF) information or handover failure (HOF) information; acquiring handover record information of the UE according to the handover event information of the UE, wherein the handover record information of the UE stores the handover state of the UE and the corresponding relationship between a source cell and a target cell on which the UE has a handover; and determining that the UE has a premature handover event between the source cell and the target cell according to the handover record information of the UE. In the embodiment of the invention, a source base station determines that the premature handover event happened between the UE and a target base station according to the handover record information corresponding to the UE, saves a signaling interaction between the source base station and the target base station, and improves the utilization efficiency of wireless network resources.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for detecting premature switching, a base station and a system. Background technique [0002] Self-Organizing Network (hereinafter referred to as SON) has the characteristics of flexibility, self-organization, strong scalability and load balancing. Some standard organizations, such as 3GPP, Wimax Forum, etc., are actively introducing SON-related technologies into the next generation. A generation of mobile communication standards. [0003] Mobility Robustness Optimization (hereinafter referred to as MRO) is an important content of SON, which ensures mobility performance through automatic configuration and automatic adjustment of mobility-related parameters, such as handover performance, to achieve optimization goals. Wherein, the mobility-related parameters include: handover parameters and cell reselection parameters. [0004] Specifically, the network detects relevant events...

AI Technical Summary

Problems solved by technology

[0006] 1. After the UE successfully switches from the source cell to the target cell, RLF occurs within a short time;

[0007] 2. The UE fails to successfully access the target cell during the handover process, resulting in a handover failure (HO Failure, HOF for short);

[0008] 3. The UE fails to send a radio resource control (Radio Resources Control, RRC) connection reconfiguration complete (such as RRC Connection Reconfiguration Complete) message to generate an RLF;

[0011] In the process of realizing the present invention, the inventor found that there are at least the following defects in the prior art: the source base station needs to exchange information with the target base station multiple times before it can know whether a premature handover event has occurred, which increases the source base station and target base station. The signaling interaction between base stations reduces the utilization efficiency of wireless network resources
