Method and device for energy saving control in home base station environment

摘要

A method and a device for energy saving control in the home base station environment are provided to solve the problem of energy saving control in the home base station environment. In the present invention, a source base station sends an energy saving control request to a target home base station, wherein the energy saving control request comprises the information of the target base station, the information of the source base station, and the type of the energy saving control request. After receiving the energy saving control request, the target home base station performs an energy saving control processing operation, and sends a result of the energy saving control processing to the source base station through an energy saving control response. If the energy saving control processing fails, the energy saving control response further comprises a reason for the failure and/or a wait time. In the present invention, by exchanging energy saving control related messages between the source base station and the target home base station, energy saving control can be implemented on a home base station in time, and the home base station can sleep or be awakened, and thereby effective energy saving of a network in the home base station environment is achieved.

1. A method for energy saving control in the home base station environment, comprising:
a source base station sending an energy saving control request to a target home base station, wherein the energy saving control request comprises information of the target base station, information of the source base station and a type of the energy saving control request, wherein the type comprises SLEEP or WAKE-UP, wherein the energy saving control request is used for indicating to the target home base station to perform energy saving control processing according to the type of the energy saving control request; and after receiving the energy saving control request, the target home base station performing an energy saving control processing operation, and sending a result of the energy saving control processing to the source base station through an energy saving control response, wherein the energy saving control response comprises the information of the target base station and the information of the source base station, wherein the information of the target base station comprises a global identifier and Tracking Area Identifier (TAI) information of the target base station, wherein the information of the source base station comprises a global identifier and TAI information of the source base station, wherein the information of the target base station in the energy saving control request further comprises an Evolved Universal Terrestrial Radio Access Network (EUTRAN) Cell Global Identifier (ECGI) and/or Closed Subscriber Group Identity (CSG ID) information of one or multiple home base station cells to which the energy saving control processing operation is performed, wherein, correspondingly, the information of the target base station in the energy saving control response further comprises an ECGI and/or CSG ID information of one or multiple home base station cells having undergone successful energy saving control processing, and wherein:
the energy saving control request is based on an S1 interface and is transmitted to the target home base station transparently through a Mobility Management Entity (MME) of a core network and, correspondingly, the energy saving control response is also based on the S1 interface and is transmitted to the source base station transparently through the MME of the core network, orthe energy saving control request is based on the S1 interface and is transmitted to a gateway of the home base station transparently through the MME of a core network, and then transmitted to the target home base station transparently and, correspondingly, the energy saving control response is further based on the S1 interface and is transmitted to the MME of the core network transparently through the gateway of the home base station, and then transmitted to the source home base station transparently by the MME of the core network.
