Problems solved by technology

However, this method requires special measurement equipment and analysis software, and the workload of measuring all the cells is quite large, and it still cannot guarantee comprehensive
In the actual network, there are often situations such as missing adjacent cells and over-area coverage, resulting in the island effect
It is easy to fail when the mobile station initiates handover in this cell

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 5 Shown is the flow chart of maintaining the neighbor list of the cell in this embodiment. After receiving the measurement control message sent by the network side, the mobile station reports the measurement report of the set reporting cell to the network side. The measurement control message includes cell list information, and the cell list information is used to indicate which cells the mobile station will measure. Wherein, the cell list is composed of the cell where the mobile station is located and its neighboring cells. The neighboring cell list is configured during network planning, and there may be missing neighboring cells. The corresponding conditions set in the measurement control signaling issued by the network side cause certain events to be triggered by cells not listed in the cell neighbor list. After the ...

Abstract

This invention puts forward an automatic maitaining neighborlist method in CDMA system in which, switching is an important method for guaranteeing normal talk between local area, yet, the successful switch is to configurate correct heighborlist information at the network side, actually, base station distribution information by network planning and the neighborlist got frame actual path test are not very accurate. This invented method will get the lost matched heighbor in network plan and add the local information not listed in the list reported by mobile station to the neightborlist after filtering and matching the unlisted areas.

Description

technical field [0001] The invention relates to a CDMA cellular mobile communication system, in particular to a method for automatically maintaining neighbor cell list information during handover measurement in the CDMA system. Background technique [0002] In the existing CDMA (Code Division Multiple Access) cellular mobile communication system, the radio frequency power of the base station is limited within a certain range (cell). When a mobile station leaves a cell and enters another cell, the signal received by the mobile station from the original cell must become weaker and weaker, while the signal it receives from the cell entering the cell will become stronger and stronger. In order to maintain the communication quality of the mobile station, it is necessary to switch the connection of the mobile station from the original base station to the newly entered base station with stronger signal. This is the concept of handover in the cellular mo...
