Cell switching control method, related devices and communication system

Abstract

The embodiment of the invention discloses a cell switching control method, related devices and a communication system, and is used for shortening a channel establishing time when an LTE (Long Term Evolution) cell is switched and improving the monitoring instantaneity after UE (User Equipment) is switched to a target cell. The cell switching control method disclosed by the embodiment of the invention comprises the following steps that: the UE receives a switch configuration message transmitted by a source base station, wherein the switch configuration message comprises PCCH (Paging Control Channel) configuration information of the target cell and BCCH (Broadcast Control Channel) configuration information; and the UE establishes a PCCH to execute network paging monitoring according to the PCCH configuration information and determines time of updating a system message after receiving paging according to the BCCH configuration information. The embodiment of the invention further provides the related devices and the communication system. According to the embodiment of the invention, the channel establishing time when the LET cell is switched is effectively shortened and the monitoring instantaneity after the UE is switched to the target cell is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching control method, related equipment and a communication system. Background technique [0002] With the development of wireless network technologies, the penetration rate of wireless terminals is also increasing, and user equipment (UE, User Equipment) is a typical wireless terminal. [0003] An important feature of UE is its strong portability. Users often move to different places during the use of UE, and the coverage of base stations that provide services for UE is limited, so UE often communicates between different base stations. switch. [0004] In the existing Long Term Evolution (LTE, Long Term Evolution) network, when the UE moves from the source cell to the target cell, it needs to initiate the process of switching the LTE cell, wherein the source cell refers to the cell served by the source base station, and the target cell is Refers to the cell served ...

AI Technical Summary

Problems solved by technology

[0006] However, it can be seen from the above-mentioned LTE cell handover process that after the UE sends the handover configuration completion message to the target base station, it needs to receive SIB2 to obtain the PCCH configuration information and BCCH configuration information of the target cell for network monitoring, so the extended The time required for channel establishment affects the real-time performance of UE monitoring after switching to the target cell
