Radio resource control connection reestablishment method, equipment and system

Abstract

The invention discloses a radio resource control connection reestablishment method, radio resource control connection reestablishment equipment and a radio resource control connection reestablishment system. The method is applied to a system comprising user equipment ,a service base station and a non-service base station and comprises the following steps that: after detecting a radio link problem, the user equipment sends a measurement report to a service cell of the service base station to ensure that the service cell prepares switching with a non-service cell of the non-service base station according to the measurement report, wherein the measurement report comprises indication information which is used for indicating that the measurement report is triggered by a radio link; and after determining a radio link failure, the user equipment triggers a radio resource control connection reestablishment process, selects a cell and initiates the radio resource control connection reestablishment for the selected cell. The technical scheme of the invention improves the success rate of the radio resource control connection reestablishment and fulfills the aim of reducing the user drop call rate and improving user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for reestablishing a radio resource control connection. 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 Finally, the user drops the call. [0003] In the LTE (Long Term Evolution, long-term evolution) system, in order to reduce the user's call drop due to various reasons, the RRC (Radio Resource Control, radio re...

Problems solved by technology

[0006] If the user equipment has not sent the handover measurement report to the serving cell or fails to send the handover measurement report to the serving cell when it is determined that RLF occurs, the serving cell cannot trigger handover to other cells, and there is no ready cell on the network side, that is Any cell outside the serving cell does not save the context information of the user equipment, resulting in the inability to re-establish the RRC connection between the user equipment and any cell outside the serving cell, making it impossible for the user equipment to switch from a serving cell with a degraded radio signal to a service cell with a weaker radio signal in time. Good other communities, it is impossible to avoid the occurrence of user dropped calls
