Embodiment Construction

[0019] Hereinafter, the present invention will be described in detail in conjunction with the accompanying drawings.

[0020] Such as figure 1 Shown is a schematic diagram of the method of the present invention. The neighbor relationship of the cell is set by the local maintenance terminal (LMT-R) or the control maintenance center (OMC) of the RNC, these relationships mainly include which NodeB's local cell and the cell adjacent to the Node B's local cell, etc., and in These information are stored in the RNC. And the radio network controller (RNC) stores the static information of the cell (including frequencies allocated by adjacent cells, etc.), which is obtained from the operation and maintenance center (OMC) or the RNC local maintenance terminal (LMT-R). Wherein, the static information of a cell includes: information that does not change frequently, such as but not limited to the following: scrambling codes, midamble codes, and cell IDs of adjacent cells.

Abstract

The invention provides a method for sharing the information of neighboring cells in multi-cell joint detection, which aims to solve the problem of interference among the plurality of cells. The method comprises the following steps of: 1, storing the static information of the cells and cell user terminal information used for the joint detection into a wireless network controller, wherein the static information of the cells comprises training sequence codes, scrambling codes and cell IDs; and 2, when a user terminal in a local cell moves to, is switched to, leaves from or enters one cell, transmitting the user terminal information of the user terminal and the static information of the local cell to a neighboring cell node B by the wireless network controller. The method has the advantages of sharing the information of the neighboring cells with low cost under the condition of not changing a conventional system structure, providing a foundation for the multi-cell joint detection and improving the performance of the multi-cell joint detection.

Description

[0001] This application is a divisional application of an application with an application date of April 14, 2006, an application number of 200610072895.5, and an invention title of "A Method for Sharing Adjacent Cell Information in Multi-Cell Joint Detection". technical field [0002] The invention relates to the field of communication network, in particular to the field of third-generation communication, and specifically relates to a method for sharing adjacent cell information in multi-cell joint detection. Background technique [0003] The Chinese meaning of TD-SCDMA is Time Division Synchronous Code Division Multiple Access. This communication technology also belongs to a technical standard of wireless communication. It was first proposed by China and based on this Radio Transmission Technology (RTT) Cooperating with international partners, it completed the TD-SCDMA standard and became a member of the CDMA Time Division Duplex Mode (CDMA TDD) standard. This is a pioneerin...
