Problems solved by technology

When the base station signal covers the sea, due to the movement of the ship, the signal may form co-channel interference with other ship-borne base stations and signals of fixed base stations (including interference between different pilot offsets of the same frequency, and the difference between the same frequency and the same pilot offset. inter-interference), it will also lead to a soft handover process in the end-user communication, which may affect the normal communication of the end-user

Embodiment Construction

[0017] The embodiment of the present invention provides a communication system based on mobile base station application, which may be a CDMA system, a GSM system, a WCDMA system, or the like. The mobile base station mainly refers to a base station whose location can be moved, and may be a shipborne base station or the like. In the embodiment of the present invention, a CDMA communication system based on application of a shipborne base station is taken as an example for description.

[0018] figure 1 A system structure diagram for communication between a CDMA communication system based on a shipborne base station application and a communication system based on a fixed base station application is provided. Communication systems based on fixed base station applications such as figure 1 The left side of the dotted line is an existing communication system, which includes a fixed base station, a base station controller (Base Station Controller, BSC) and a mobile switching center (...

Abstract

The embodiment of the invention provides a mobile base station application-based communication system, a mobile base station application-based device and a mobile base station application-based method. The communication system comprises a base station location registration management module BLR, wherein the BLR is in communication connection with a mobile switching centre MSC and is used for acquiring and storing related information on a mobile base station and a fixed base station, recognizing a neighbor relationship between the base stations according to the related information, calculating the distance between the mobile base station and the fixed base station and adjusting the transmission power of the mobile base station according to the distance. The embodiment of the invention can solve the problem of the interference between the mobile base station and the fixed base station.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication system and device based on mobile base station application and a method for avoiding signal interference between the mobile base station and other base stations. Background technique [0002] In a communication system, a base station is generally fixedly installed, and its location, frequency point, pilot offset (PILOT offset) and other offsets are determined during network planning. For high traffic absorption and emergency communication needs, mobile emergency communication vehicle-mounted base stations can be used. In this case, the position, frequency point, and pilot offset of the base station are fixed during operation. Base station cells are divided into two types: omnidirectional cells and directional cells, and the direction of directional cells is fixed. In order to distinguish different base station cells, the system is designed to use different pilot...
