Inter-base-station cell switching method and system

Abstract

The invention provides an inter-base-station cell switching method and system. The method includes that a source cell sends an inter-base-station cell switching request when a target cell determined according to signal quality detecting information reported by UE is a neighbor cell of the source cell and is in the same base station of the source cell; the target cell receives the inter-base-station cell switching request, reserves resource required by the UE for residing in the target cell and replying switching request confirmation information to the source cell; the source cell receives the switching request confirmation information and sends RRC reconfiguration request information to the UE; the target cell receives reconfiguration completion information sent by the UE, configures an S1 common channel, updates a mark of a cell of the UE newly resides and a UE mark distributed for the UE by the target cell, and sending resource release indication information to the source cell; the source cell receives resource release indication information and performing corresponding resource release operation according to switching state information of the UE. According to the embodiment of the invention, decrease of time delay of switching between cells of the same base station by the UE is realized and the switching performance is improved.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for switching between cells in a base station. Background technique [0002] With the development of wireless mobile communication technologies, mobile communication technologies continue to pursue higher system performance requirements. These system performance requirements include maintaining a good user experience when users move. This belongs to the category of mobility requirements, that is, handover performance requirements. From the perspective of mobile communication equipment deployment, user mobility scenarios can be divided into three types: cross-core network handover, cross-base station cell handover, and cross-base station cell handover. Taking the new generation of mobile communication standard LTE (LongTerm Evolution, long-term evolution technology) as an example, for the first two handover types, the LTE standard provides two handover pr...

Problems solved by technology

Taking the new generation of mobile communication standard LTE (Long Term Evolution, long-term evolution technology) as an example, for the first two types of handover, the LTE standard provides two handover processes of S1 handover and X2 handover The LTE standard does not give an implementation process for inter-cell handover of the same base station. Although it can be implemented through S1 handover, this implementation method does not necessarily exist for interactive signaling with the core network for inter-cell handover within the base station. , resulting in an increase in switching anomalies and a prolongation of switching time
