Embodiment Construction

[0030] The present invention will be further described below in conjunction with drawings and embodiments.

[0031] An energy-saving control method for a home base station network, such as Figure 4 shown, including the following steps:

[0032] Let the number of users in the coverage area of ​​the home base station be U, the pilot signal threshold be W, and the upper limit of each home base station to serve users is 4;

[0033] When U=0, the home base station enters a sleep state;

[0034] When U is not 0, first find the home base station with U=1, judge whether the user belongs to the CSG list, if not, refuse access, then the home base station enters the sleep state; if it belongs, record the pilot received by the HUE Corresponding femtocells with signal power greater than W;

[0035] Assuming that the number of Femtocells is Y at this time, the Femtocell gateway judges whether the Y Femtocells have idle resources. If so, the Femtocell gateway allows the user to access th...

Abstract

The invention relates to an energy-saving control method for family base station networks, and discloses a novel energy-saving mechanism based on a family base station network system in consideration of the sleep mode of family base stations. In an environment with the dense deployment of family base stations, the number of active family base stations is reduced by causing unnecessary family base stations in a network to sleep via a method of the sleep of the family base stations, thus effectively realizing energy-saving for the network. According to the energy-saving control method disclosed by the invention, the family base stations with a low number of family base station users are judged, and when the users can be served by other family base stations, then the family base stations enter in a sleep state; or else, the family base stations keep an active state, wherein the judgement is realized by a family base station gateway.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an energy-saving method for a home base station network. Background technique [0002] In a cellular network, about 2 / 3 of voice services and more than 90% of data services take place indoors. Therefore, for operators, providing good indoor coverage for users' voice, video and high-speed data services becomes increasingly important. In the LTE-A system, the loss of penetration leads to the deterioration of signal reception quality, which seriously hinders the indoor data service quality. In order to improve the overall performance of the network, the heterogeneous network is introduced into the LTE-A network. The heterogeneous network is composed of macro base stations and low energy consumption nodes (such as picocell, femtocell, relays), the purpose of which is to make the network closer to end users. In this way, the quality of the wireless link will be improved due to...
