Abstract

The invention relates to the field of time division duplex communication networks, in particular to technique for balancing uplink and downlink load in a time division duplex communication network. A load balance control method comprises the following steps: monitoring an uplink wireless channel resource occupation rate and a downlink wireless channel resource occupation rate in an uplink and downlink asymmetric network; and re-orientating uplink and downlink symmetric services in the uplink and downlink asymmetric network or switching to a uplink and downlink symmetric network when determining the resources of the uplink and downlink asymmetric network are limited according to the uplink wireless channel resource occupation rate and the downlink wireless channel resource occupation rate. The invention also provides a load balance control device. Due to the switching of the uplink and downlink symmetric services from the uplink and downlink asymmetric network to the uplink and downlink symmetric network when determining the resources are limited, the method and the device flexibly adapt to the service change of a current system and achieve reasonable load balancing.

Description

technical field

[0001] The invention relates to the field of time-division duplex communication networks, in particular to a technology for balancing uplink and downlink loads in a time-division duplex communication network. Background technique

[0002] In a wireless communication system, communication methods can be divided into frequency division duplex and time division duplex. In TDD technology, the channel through which users send data is called an uplink wireless channel, and the channel through which users receive data is called a downlink wireless channel. The time division duplex technology uses different service time slots for the uplink wireless channel and downlink wireless channel occupying the same frequency, and the allocation ratio of the two service time slots is called the uplink and downlink time slot ratio. When a large number of services in the system are asymmetrical services (such as downloading, video-on-demand, etc.) that are dominated by downlink ...
