Problems solved by technology

It can be seen that although the above-mentioned method of searching for CSG cells within the scope of the TA is relatively simple, it is meaningless for the UE to search for CSG cells in most of the time, which will lead to low efficiency of the solution and increase the battery life of the UE. unnecessary consumption of

Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] The basic idea of ​​the present invention is: after the UE camps on or moves into a macro cell, it first establishes a search target list, and the search target list only includes the previously searched CSG cells covered by the current macro cell and the previously unsearched CSG cells. CSG cells that are available and accessible, and then periodically traverse the search target list to measure the CSG cells within the scope of the search target list, so as to realize the search for CSG cells in a smaller range.

[0044] Such as figure 1 Shown, the present invention mainly comprises the following steps:

[0045] Step 101. The UE establishes a search target list according to the pre-established search set for each CSG cell accessi...

Abstract

The invention provides a method for searching a closed signed user group (CSG) cell and equipment thereof. UE establishes a searching target list according to a searching set established for the UE to access each CSG cell, wherein the searching set comprises a macro-cell covering corresponding CSG cell; and the UE searches the CSG cell in the searching target list through periodic measurement. The application of the invention can narrow down the searching range of CSG cell by the UE and cause the UE to conduct the searching of the CSG cell within the relevant macro-cell of the CSG cell so as to reduce unnecessary searching tasks, thereby improving the searching efficiency and reducing the meaningless consumption of a UE battery.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and equipment for autonomously searching closed subscriber group (Closed Subscriber Group, CSG) cells by user equipment (UE, User Equipment). Background technique [0002] In the future Evolved-Universal Terrestrial Radio Access (E-UTRA) system, home base station equipment (Home eNB) will be widely deployed, and accordingly the concept of CSG cell closely related to Home eNB is introduced. The CSG cell is a part of the Public Land Mobile Network (PLMN, Public Land Mobility Network), which is served by the home base station (Home eNB). The CSG cell is different from the macro cell served by the macro base station. The access of the CSG cell is restricted. Yes, only a group of specific users authorized by the owner of the Home eNB can access, and other users have no access authority. [0003] Just because the CSG cell is different from the macro cell, the mobilit...
