Wireless digital repeater station with carrier scheduling function and method for realizing carrier scheduling

Abstract

The invention provides a wireless digital repeater station with the carrier scheduling function and a method for realizing carrier scheduling. The method is characterized in that when the traffic statistics result reported by the wireless digital repeater station exceeds the set range of a base station, the wireless digital repeater station identifies an adjacent wireless digital repeater station satisfying the requirement of carrier scheduling through information interaction with a network control center and sends a command of starting carrier scheduling to the adjacent wireless digital repeater station; the two wireless digital repeater stations simultaneously start a relay and forward system and establish the relation between relay and forward; and the traffic exceeding the load of the wireless digital repeater station sending the command of carrier scheduling is scheduled to the relay channel of the adjacent wireless digital repeater station through the relay channel of the wireless digital repeater station sending the command of carrier scheduling and then is scheduled to a covering system of the base station corresponding to the wireless digital repeater station sending the command of carrier scheduling by frequency selecting and frequency shift, thereby establishing traffic relation and completing carrier scheduling. The invention can not only make full use of the resources of the repeater station and lower the cost, but also effectively improve the traffic quality.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless digital repeater with a carrier scheduling function based on same-frequency and different-frequency forwarding and a method for realizing carrier scheduling between the wireless digital repeaters. Background technique [0002] As we all know, the best cellular communication system network deployment mode generally adopts the coverage method of "base station + repeater". Base stations are arranged in areas with relatively concentrated traffic, and repeaters are used to extend coverage in areas with less traffic around them. like figure 1 As shown, the traffic capacity of base station 1 and repeater A1, and the traffic capacity of base station 2 and repeater A2 are planned according to the theoretical traffic of the area covered by them. When the traffic in the blind area 1 increases, the system configuration of the base station 1 must be increased to...

Problems solved by technology

Since this solution uses a controller to control the switching mode of multiple groups of radio frequency switches, it is not only easy to cause equipment failure, but also increases the transmission delay of the equipment; and the equipment uses a separate access and transmitting antenna system, which is easy to form a self-excited system

Especially, when the frequency interval of two systems working at the same time is relatively close (such as 458MHz and 468MHz), it is easy to affect each other and cause interference
