Embodiment Construction

[0051] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0052] image 3 It shows the flow chart of the cell reselection method for a cell with CSG under multi-standard provided by the embodiment of the present invention, as shown in image 3 As shown, the steps include:

[0053] Step 301: After successfully camping in the cell, the user terminal UE searches for and saves the CSG information of the cells with the strongest frequencies in all adjacent cells;

[0054] Step 302: Perform high-priority frequency cell measurement, and perform same-frequency cell measurement and / or same-priority and low-priority frequency cell measurement according to the measurement results;

[0055] Step 303: According to the high...

Abstract

Disclosed are a cell reselection method and device with a closed subscriber group (CSG) cell in multi-format. The method includes: after user equipment (UE) resides in a cell successfully, searching for and storing the CSG information about the cell with the strongest frequency point from all the neighbours (S301); performing high priority frequency point cell measurement, and performing identical frequency point cell measurement and / or identical priority and low priority frequency point cell measurement according to the measurement result (S302); determining a high priority frequency point candidate cell, an identical priority frequency point candidate cell and a low priority frequency point candidate cell according to a high priority frequency point value, an identical priority frequency point value and a low priority frequency point value (S303); and determining a CSG reselection target cell and a non-CSG reselection target cell from the high priority frequency point candidate cell, identical priority frequency point candidate cell and low priority frequency point candidate cell according to a pre-stored CSG whitelist and the stored CSG information (S304). The present invention is suitable for a mobile communication system with a mix of CSG cells and non-CSG cells.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a cell reselection method and device for a cell with CSG in a multi-standard system. Background technique [0002] In the Universal Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, UTRAN) and the Evolved Universal Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, EUTRAN) system, cells can be divided into closed subscriber groups (Closed Subscriber Group) , CSG) cells and ordinary cells (also known as non-CSG cells). The CSG cell is a part of the Public Land Mobile Network (PLMN) and is served by Home NodeB / Home eNodeB (HNB / HeNB). Compared with ordinary cells, CSG cells Generally, it has the advantages of cheap billing, flexible and optional services, etc., but the camping is limited. Only when the CSG ID stored in the user card matches the ID of the CSG cell to be camped on can the camping be successful. [0003] A...
