A method and system for configuring adjacent cells

Abstract

The invention relates to the field of mobile communication, in particular to a method and system for configuring adjacent cells. The present invention detects the adjacent cell of the source cell; identifies the type of the first base station corresponding to the adjacent cell; establishes an X2 connection between the first base station and the second base station corresponding to the source cell according to the type; if the If the X2 connection is established successfully, mark that the communication between the first base station and the second base station is through the X2 link; otherwise, mark that the communication between the first base station and the second base station is through the S1 link. The efficiency of adjacent cell handover is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for configuring adjacent cells. Background technique [0002] After several generations of development, mobile communication technology has become the most widely used communication method in people's daily life. The global 4G network represented by LTE network continues to increase, and the number of users increases steadily. The global 4G market has entered a period of rapid development from its initial stage. With the development of LTE, there are more and more base stations, and the complex neighbor relationship will lead to missed cells and wrong cells, which will lead to the failure of switching cells and call drop. Therefore, accurate neighbor relationship configuration is the basic requirement to ensure the performance of the mobile network. . [0003] The existing methods for configuring the neighbor relationship mainly include the following two ...

However, the ANR method has many limitations. For example, only a terminal that supports CGI reporting can detect the missing neighbor cell information. The measurement is based on the frequency point instead of the neighbor cell list, and only the neighbor cells with pre-configured frequency points can be measured. These Restrictions lead to incomplete collection of neighboring cell information; more importantly, the measurement information reported by the terminal does not include the base station type and the link type between the base station corresponding to the source cell and the base station corresponding to the neighboring cell; Try to configure the type of base station corresponding to the target cell. If the base station type is incorrectly configured, the cell handover will fail, resulting in call drop and affecting user experience. In addition, the X2 link can enable direct communication between adjacent base stations, thus ensuring that users are in the entire network. Seamless handover in the network, and the S1 link enables the base station to communicate with the core network, and the core network forwards data to other base stations, so the communication efficiency of the S1 link is lower than that of the X2 link; since each LTE base station contains an S1 link However, it does not necessarily include the X2 link. When performing cell handover, the source base station generally tries to establish an X2 connection with the target base station first, and then sends the data of the mobile terminal to the target base station through the X2 link. The S1 link communicates with the target base station

Therefore, if it is not known whether there is an X2 link between the base station corresponding to the source cell and the base station corresponding to the target cell before cell switching, the efficiency of cell switching will be reduced
