Method, system and apparatus for saving energy for base station

Abstract

A method, system and apparatus for saving energy for a base station are applied to the field of communication technology. The energy-saving method comprises: sending a second activation request to a capacity boosting base station if the number of user equipment which sends service requests in the coverage area of a coverage base station is higher than a first threshold value, wherein the second activation request is used for requesting the capacity boosting base station which is in a dormant state to go from the dormant state to an intermediate state and the intermediate state indicates that in the intermediate state, the capacity boosting base station bears user equipment in a connection state but does not bear user equipment in an idle state; and shifting the connection of the user equipment to the capacity boosting base station in the intermediate state after the capacity boosting base station goes into the intermediate state. The invention further provides an apparatus and system for realizing the method.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for energy saving of a base station or a cell. Background technique [0002] Today's wireless communication services have developed from low-speed voice services to high-speed multimedia data services. In order to meet the growing demand for high capacity and high data rates, operators often apply wireless access technologies with higher capacity and transmission rates. On the basis of providing basic network coverage, base stations or cells of different standards or shapes are deployed in the same area for capacity enhancement. Here we refer to the network that provides basic network coverage as Network 1, and the network formed by the base stations or cells that provide capacity enhancement as Network 2, and for the convenience of description, the base stations or cells in Network 1 are collectively referred to as Coverage Base Station...

AI Technical Summary

Problems solved by technology

[0007] When the above two base station energy-saving methods are applied to the above-mentioned scenarios, it is easy to cause two serious problems: first, when the coverage base station or cell users need to initiate a short-term service that can only be carried by the capacity base station or cell, since the coverage base station Or the total load of the cell does not reach the level of opening the capacity base station or cell, and the capacity base station or cell will not be opened, which will cause the network to be unable to carry the service and seriously affect the user experience; secondly, even if the capacity base station or cell can be opened in time to carry the service , after the service is over, the capacity base station or cell will enter the dormant state due to low load. When the number of such users is large and not concentrated, it will cause the capacity base station or cell to be turned on and off frequently. During this process, the idle state Users frequently initiate different-standard reselection, which increases terminal power consumption. At the same time, the different-standard update (such as RA / TA) accompanied by different-standard reselection will bring serious signaling impact to the network.
