Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] When the terminal measures the downlink reception level, it mainly measures the broadcast control channel (Broadcast Control Channel, BCCH). In the loose multiplexing scenario of the 4*3 network, the downlink measurement of the terminal can measure the actual adjacent cell level more accurately; but in the tight multiplexing scenario, due to the superposition of co-channel interference, especially the adjacent cell When using the same frequency point, the measurement result will have a large error.

[0059] Such as figure 1 As shown, at the location of terminal 01, BCCH has multiple neighboring cells with the same frequency in close distances. Assume that the frequency point of BCCH in the serving cell is f0, and there ar...

Abstract

The application discloses a mobility management method, device and system, belonging to the communication field. The method includes: the BTS receives an uplink receiving signal, and the uplink receiving signal includes the TSC sent by the first MS; the BTS calculates the uplink receiving level of the first MS according to the uplink receiving signal and the TSC corresponding to the first MS; the BTS reports to the BSC The uplink receiving level of the first MS, the BSC receives the uplink receiving level of the first mobile station MS reported by at least one BTS, each uplink receiving level corresponds to a cell; the BSC determines the first MS’s uplink receiving level according to the uplink receiving level of the first MS A signal quality of each cell where the MS is located; the BSC performs mobility management on the first MS according to the signal quality of each cell where the first MS is located. This application replaces the downlink reception level with the uplink reception level in the presence of co-channel interference, thereby achieving the effect of mobility management for MSs.

Description

technical field [0001] The present application relates to the communication field, and in particular to a mobility management method, device and system. Background technique [0002] For mobile communication networks, air interface resources are the most valuable resources for operators. The Global System for Mobile communications (GSM) occupies the most precious spectrum. It is a common trend in the development of global mobile networks to reuse spectrum resources occupied by GSM for Long-Term Evolution (LTE). [0003] In the traditional GSM cellular networking mode, the basic repeating unit adopts 4*3 networking, that is, 4 base stations, each base station provides 3 cells, and adjacent cells use different frequency points. The terminal will continuously monitor the downlink receiving level (also called downlink receiving power) of each cell where it is located, and then use it in the judgment process of cell reselection and cell switching. For example: when the termina...
