Method for energy conservation for wireless access network

Abstract

The invention discloses a method for energy conservation for a wireless access network. The method includes the steps that S1, in the stage that network traffic is reduced, a base station with the minimum network traffic is selected as a closed base station; S2, a compensation base station combination of the closed base station is selected through a selecting method for compensation base station combination; S3, if the closed base station needs to be closed, compensation is carried out on the closed base station, and the closed base station enters into a dormant state; S4, in the stage that the network traffic is increased, the network traffic of compensation base stations in an area compensation base station set is forecast, and a compensation base station with the maximum forecast network traffic is selected as a preselected base station; S5, when the forecast network traffic of the preselected base station exceeds maximum network traffic loads of the preselected base station, the closed base station compensated by the preselected base station is started. On the premise of ensuring the network traffic, the purpose of the energy conversation is achieved to the maximum, and the energy conversation is optimized as far as possible while interference is reduced.

Description

technical field [0001] The invention relates to the field of wireless network energy saving, in particular to a wireless access network energy saving method. Background technique [0002] At present, energy consumption has become one of the issues of general concern in the global industry. The development of society and economy will inevitably lead to a continuous increase in energy consumption in the future, which makes people pay more attention to efficient energy-saving solutions. Globally, the energy consumed by the information and communication industry accounts for between 2% and 10% of total energy consumption every year, and is expected to increase tenfold in the next decade. Among the energy consumption generated by the communication network, due to the large number of nodes in the access network, the energy consumed accounts for nearly 80% of the entire network, while the energy consumption of other parts (including core network and network management equipment, e...

Problems solved by technology

However, this method can only be applied to the energy saving of a single base station, and requires the use of adaptive load balancing technology to balance the load. It cannot perform macro energy-saving control for the base stations in the entire area. At the same time, it does not consider the impact of closing the carrier frequency on coverage and interference. In the process of turning on and off the base station, it is very good to avoid the impact caused by the energy saving process
