A converged network scheduling method and device

Abstract

The invention discloses a converged network scheduling method, which is applied in a system of integrated private network and large network. When it is determined that a train enters the coverage of a private network cell, the control channels of M private network single cells are activated in sequence; When it is determined that the train leaves the coverage area of ​​the private network cell, the control channels of M private network single cells are sequentially deactivated; where M is a positive integer. The invention also discloses a converged network scheduling device.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for converged network scheduling. Background technique [0002] With the rapid development of high-speed rail construction, the network optimization methods of ordinary railways can no longer guarantee the user network quality in high-speed mobile scenarios, and it is necessary to build a dedicated network for high-speed rail coverage. [0003] At present, the Long Term Evolution (LTE, Long Term Evolution) high-speed rail private network is built in a different-frequency network. The railway private network is constructed independently and superimposed on the normal macro network. The networking method is simple and can avoid interference to the greatest extent. However, China Mobile's frequency spectrum is outdoor F-band 20M and D-band 60M. Under the background of the mainstream 20M bandwidth network, there are only 4 LTE frequency p...

AI Technical Summary

Problems solved by technology

However, China Mobile's frequency spectrum is outdoor F-band 20M and D-band 60M. Under the background of the mainstream 20M bandwidth network, there are only 4 LTE frequency points in the whole network. If one is dedicated to the high-speed rail private network, there will be serious spectrum resources. waste problem

[0004] If the same-frequency network is used, spectrum resources can be efficiently used, but for users who take high-speed rail, when the mobile terminal is transferred from the existing Global System for Mobile Communications (GSM, Global System for Mobile Communication) high-speed rail private network FR (fast return) When connecting to the LTE high-speed rail private network, since FR is an autonomous behavior of the terminal that is not controlled by the network side, the terminal is likely to return to the LTE large network at the same frequency point instead of the LTE high-speed rail private network, which will affect user perception

In addition, when the same-frequency private network overlaps with the same-frequency large network, since the high-speed rail private network is in a strip structure, the coverage length is as long as several kilometers, which will affect the network quality of the large network. There is an unavoidable interference problem of mod3 and mod6 between the network and the big network;
