Method and device for determining cell coverage radius and neighboring cell relation

Abstract

The invention discloses a method and a device for determining cell coverage radius and a neighboring cell relation. UE is preset to increase a position measuring function, measures reference signal received power RSRP and geographical position information of the current cell, and reports the RSRP and the geographical position information to a base station; and the base station determines the coverage radius of the current cell of the UE according to a preset central position of the current cell of the UE and the RSRP and the geographical position information reported by the UE, and the base station determines the neighboring cell relation between the cells according to the coverage radius of various cells after acquiring the coverage radius of the various cells. The cell coverage radius and the neighboring cell relation can be accurately determined by adopting an automatic mode so as to achieve the network self-optimization effect.

Description

technical field [0001] The invention relates to wireless network communication technology, in particular to a method and device for determining the coverage radius of a cell and a method and device for determining the relationship between adjacent cells. Background technique [0002] A Long Term Evolution (LTE, Long Term Evolution) network is a flat network. figure 1 is the structure diagram of LTE network, see figure 1 , the LTE network consists of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved UTRAN) base station eNB (Evolved Node Base) and an Evolved Packet Switching Center EPC (Evolved Packet Core). The E-UTRAN includes a collection of eNBs connected to the EPC through the S1 interface, and the eNBs are connected through the X2 interface, and each eNB includes more than one cell. [0003] The mobility of the terminal (UE) is the main feature in the wireless communication system, it is mainly realized by the cell reselection in the idle mode of ...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the above description that the existing methods of determining the coverage radius of a cell and the method of determining the relationship between neighboring cells of each cell mainly rely on artificial implementation. For example, the staff must use drive test tools to measure the coverage radius of each cell on the spot. , the staff must manually determine the neighbor relationship of each community according to the coverage radius of the community, and the staff must configure the neighbor relationship in the system, etc., which greatly increases the workload of personnel and reduces the efficiency and automation of the system In addition, artificial implementation is likely to cause inaccurate cell coverage radius measurement results due to staff carelessness and aging measurement tools, as well as inaccurate neighbor relationship settings set by personnel, thus failing to meet system requirements and greatly reducing system performance.
