Cell system information acquisition method and device

Abstract

The invention discloses a cell system information acquisition method and a cell system information acquisition device, which relate to the field of communication and aim to solve the problems of normal acquisition of member closed cell system information after the change of a primary synchronization code (PSC) / physical cell identity (PCI) of a closed cell. The method comprises the following steps of: determining a target closed cell; acquiring the PSC / PCI of the target closed cell; if the PSC / PCI of the target closed cell is different from a stored PSC / PCI, starting a timer, and if the target closed cell is still detected after a time set by the timer, transmitting a first measurement report to a network side, wherein the first measurement report comprises the PSC / PCI of the target closed cell; receiving measurement control information which is transmitted based on the first measurement report by the network side, wherein the measurement control information indicates the acquisition of the system information of the target closed cell; and acquiring the system information of the target closed cell according to the measurement control information. The embodiment of the invention can be applied to the process of switching user equipment (UE) into the closed cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for acquiring cell system information. Background technique [0002] During the handover process of a user equipment (User Equipment, UE) to a closed subscriber group (Closed Subscriber Group, CSG) cell in a private network, the UE needs to acquire system information of the CSG cell to be accessed. [0003] The method for the UE to obtain the system information of the CSG cell provided by the prior art may include: [0004] After the UE detects the CSG cell according to the fingerprint information or the network configuration, and determines the target CSG cell to be accessed, the UE acquires the Primary Synchronization Code (Primary Synchronization Code, PSC) / Physical Cell Identity (Physical CellIdentity, PCI) of the target CSG cell ); the UE compares the PSC / PCI of the CSG cell with the PSC / PCI of the CSG cell stored in the fingerprint information, and jud...

AI Technical Summary

Problems solved by technology

For example: when the home base station (Home NodeB, HNB) to which the CSG cell belongs performs on / off operation, the PSC / PCI of the CSG cell will change

When the PSC / PCI of the CSG cell changes, the method provided by the existing technology may not be able to obtain the system information of the member CSG cell normally, resulting in problems such as the UE being unable to access the member CSG cell and the UE failing to perform CSG cell handover.
