Problems solved by technology

[0003] When the UE selects a cell for the first time or performs cell reselection, it first indicates a Public Land Mobile Network (Public Land Mobile Network, PLMN), and the UE selects a cell in the indicated PLMN to camp on. match, so that UEs that support UMTS will camp on cells that support S-UMTS, and UEs that support S-UMTS cannot give priority to camping on cells that support S-UMTS
The wrong cell camping of the UE causes the UE to be unable to initiate services or fully use its own functions in the cell where the UE is camped, which reduces the intelligence of the UE in cell selection or cell reselection, and affects the UE camping in a better cell. Affecting the experience of users initiating business

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] The scenario in which the UE performs cell selection may include that the UE performs cell selection for the first time or performs cell reselection, and the selection standard for the UE to perform cell selection may be a standard determined by detecting the radio signal strength and / or radio signal quality of the cell.

[0050] See figure 1 , which provides a schematic flowchart of a method for cell selection according to an embodiment of the present ...

Abstract

Embodiments of the invention disclose a cell selection method and user equipment. The method comprises the following steps: the user equipment (UE) obtains system attribution information of a cell, wherein the system attribution information comprises a cell indication information or a cell access restriction information, the cell indication information comprises at least one of a system type of the cell, a bandwidth supported by the cell, frequency point information of the cell and a cell uplink or downlink bandwidth scaling factory, and the cell access restriction information comprises first access restriction information and / or second access restriction information; and the UE performs cell selection operation according to the system attribution information of the cell. The UE can rightly reside in the cell, and intelligent performance of cell selection or cell reselection performed by the UE is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of cell selection and cell reselection, and in particular to a cell selection method, user equipment and a base station. Background technique [0002] The traditional Universal Mobile Telecommunications System (UMTS) uses both uplink and downlink bandwidths of 5MHZ. In order to improve the uplink capacity of the system, the uplink bandwidth or downlink bandwidth of the system can be divided into N subcarriers, and the bandwidth of each subcarrier is less than or equal to 5 / N (MHz), the system using this uplink or downlink subcarrier is called a scalable universal mobile communication system (ScalableUniversalMobileTelecommunicationsSystem, S-UMTS). Different user equipment (User Equipment, UE) can access different uplink subcarriers, and since there is no mutual interference between different uplink subcarriers, the uplink capacity is improved. ...
