Sleep control method for small base station

Abstract

The invention discloses a control method for small base station dormancy. The method comprises the steps as follows: 1), a load value in a small base station coverage range is detected; 2), a frequency spectrum threshold value for small base station activation is set according to the load value detected in the step 1); 3), idle spectrum resources are detected; and 4), a radio frequency component of a small base station is controlled to be opened and closed according to the detected load value and the size relation between the idle spectrum resources and the preset frequency spectrum threshold value, so that the small base station works in an activation or dormancy state. According to the control method for the small base station dormancy, the idle spectrum resources are combined with the traffic in the small base station coverage range, and the resources and the traffic are taken as control conditions for the small base station dormancy; and at the same time, the phenomena that the idle spectrum resources are insufficient and the small base station is activated invalidly or reuses frequency spectrum resources of users nearby forcefully after activation are avoided, so that the network energy consumption can be reduced, and the energy efficiency of a system is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for controlling dormancy of a small base station. Background technique [0002] With the popularity of smart mobile devices and the advent of the era of innovative mobile data services, people's requirements for broadband mobile communications are getting higher and higher. Small base station networks include microcells, picocells, etc., which can improve system capacity and coverage. They can be used in busy areas to absorb traffic, or in blind spots to supplement coverage. They can also cover local areas, such as urban coverage and suburban areas. cover. The introduction of small base station networks can meet people's requirements for huge data capacity and high-quality services, and because of its easy deployment and low cost, it has great development prospects. The research on the development and deployment of small base station networks has ...
