Abstract

The invention relates to a method for selecting address of base station in multiple system, considering co-channel spuious interference, the method includes: obtaining radio-frequency performance parameters of network base stations (31,41,42) and a terminal device (32) in each system; determining the maximum and minimum distance of the network base stations (31,41,42) and a district (2) with near-far effect in each system; selecting addresses of network base stations in each system from the optional range besides the maximum (23) and the minimum (21) distance. Comparing with tradtional method, the method can not need network at 1:1, networks more neatly, reduces networking cost greatly, does not need to increase frequency interval to reduce near-far effect, saves frequency spectum resource. Comparing with existing patent, the invention has different analysis, has wider range of application, which is useful for analyzing and solving near-far effect interference between networks or internal of network in same frequency band for CDMA, WCDMA, TD-SCDMA with fixing carrier frequency.

Description

technical field

[0001] The invention relates to the construction of a wireless communication network, in particular to a base station site selection method in an actual multi-system coexistence environment. Background technique

[0002] With the wide application of wireless communication technologies, multiple wireless networks often exist simultaneously in the same area, such as the coexistence of one CDMA2000 1X system and one WCDMA system, or the coexistence of two CDMA2000 1X or two WCDMA systems. If the two networks work in the same frequency band and the base stations are not completely co-sited, when the terminal of one system is far away from the base station of the network and close to the base station of the other system, the problem of near-far effect may occur. For two different wireless communication operators, the base stations of the two networks often do not co-site, and the terminal usually does not switch between the two networks. Therefore, the near-far e...
