Embodiment Construction

[0050] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] The method is based on the LTE broadband wireless mobile communication system as shown in FIG. 1 . In the figure, ASGW (Access Service Gateway, access service gateway) represents the access service gateway entity of the broadband wireless mobile communication system, which is used to complete functions such as user access in the system and routing and forwarding of signaling and services in the system. eNodeB represents a new type of Node B logical node, which is used to complete the physical layer of the air interface and some high-level protocols, and is the node that the mobile terminal visits for the first time when it accesses the system. The RRMServer (radio resource management server) in the figure is an optional functional entity, which is mainly used to assist in the completion of the radio resource management process between cells in the broadband wi...

Abstract

The utility model relates to a method for the terminal operating adjacent cell measurement in the long-term evolution system, comprising the following steps: (1) measuring control information is received by the terminal from the network side; (2) an adjacent cell is measured by the terminal according to the appointed measuring method received from the measuring control information or according to the discretionary measuring method by the terminal. Same frequency measurement can be adopted to the adjacent cells in the same layer, and either the same frequency measurement or the different frequency measurement is adopted to the adjacent cells in the same layer according to the circumstance of the adjacent cells; the different frequency measurement is adopted to the adjacent cells in different layers, and either the same frequency measurement or the different frequency measurement is adopted to the adjacent cells in different layers according to the circumstance of the adjacent cells. The utility model offers various technical proposals aiming at the terminal receiving the adjacent cell in the LTE system, solves the problem of no relevant measuring method in the prior LTE. Furthermore, the utility model eliminates the cases of partly receiving or no receiving of the adjacent cell information and improves the receiving accuracy.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for a terminal to measure adjacent cells, in particular to a method for a terminal (UE) in a long-term evolution (LTE) system to measure adjacent cells and a terminal in the LTE system. Background technique [0002] In a WCDMA (Wideband Code Division Multiple Access) communication system, the same-frequency adjacent cell means that the carrier frequency of the adjacent cell is the same as the carrier frequency of the serving cell and the UE can receive the target cell without adjusting the receiver frequency of the terminal. common channel information, the inter-frequency cell is that the carrier frequency of the neighboring cell is different from the carrier frequency of the serving cell. [0003] In a WCDMA communication system, the method for UE to measure adjacent cells is as follows: a1: the network sends a system message or a dedicated measurement control message,...
