Abstract

The invention relates to an optimization method of a measurement control message of a TD-SCDMA system, a method for acquiring a co-frequency interference neighbor cell list by a terminal and the terminal. The measurement control message at least comprises ID information of co-frequency neighbor cells of the cell located by the terminal, and the optimization method of the measurement control message comprises the step of adding auxiliary frequency point information of different-frequency neighbor cells of the cell located by the terminal in the measurement control message. The method for acquiring the co-frequency interference neighbor cell list by the system terminal comprises the steps of using the terminal for receiving the measurement control message which is issued from a network and comprises the auxiliary frequency point information of the different-frequency neighbor cells of the cell located by the terminal, using the terminal for acquiring the information of a first neighbor cell with a main frequency point which is the same with a working frequency point of the terminal from the measurement control message, using the terminal for acquiring the information of a second neighbor cell with an auxiliary frequency point which is the same with the working frequency point of the terminal from the measurement control message, and using the terminal for acquiring the co-frequency interference neighbor cell list through the acquired information of the first neighbor cell and the information of the second neighbor cell.

Description

technical field [0001] The present invention relates to a method for optimizing a measurement control message, a method for a terminal to obtain a complete list of neighboring cells of the same frequency and the terminal, more specifically, a method for optimizing a measurement control message in a TD-SCDMA system, and a method for a terminal in a TD-SCDMA system to obtain a complete The method of same-frequency adjacent cell list and TD-SCDMA system terminal. Background technique [0002] In order to improve the system capacity of the TD-SCDMA (Time Division Synchronous Code Division Multiple Access) system, N-frequency point networking technology is introduced in the TD-SCDMA system: (1) Each cell is configured with N carrier frequencies, one of which is the main carrier The other N-1 are auxiliary carrier frequencies. The one that carries P-CCPCH (Primary Common Control Physical Channel) is the main carrier frequency, and the one that does not carry P-CCPCH is the auxilia...
