Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail in conjunction with the accompanying drawings.

[0026] As shown in Figure 1, it is a schematic diagram of the method of the present invention. Set the adjacent relationship of the cell through the local maintenance terminal (LMT-R) or the control and maintenance center (OMC) of the RNC, these relationships mainly include which Node B's local cell and the cell adjacent to the Node B's local cell, etc., and This information is 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 present invention relates to the field of communication network, especially relates to the third generation communication, specifically, the present invention provides a method of sharing information of adjacent cell in the multi-cell combination detecting process. The present invention includes the steps as follows to solve the problem of interference among cells: a wireless network controller or the local maintaining terminal of the cell node B or the control maintaining center transmits static information of the adjacent cell to each cell node B; the wireless network controller transmits the static information and user terminal information of at least one adjacent cell of the local cell to each node B; the local cell node B stories the static information and user terminal information of the adjacent cell in the core control board of the local cell node B. The good effects of the present invention reside in that: the information of the adjacent cells can be shared without changing the current system structure, and a foundation of the multi-cell combination detecting is provide, and the performance of the multi-cell combination detecting is improved with a low cost.

Description

technical field [0001] 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 [0002] 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 pioneering work in China's mobile communication industry, and it is also China's contribution to the development of the third generation of mobile communication. In competition with the 3G standards proposed by Europe and the United States, TD-SCDMA proposed by China has...
