Embodiment 1

[0037] figure 2 It is a flowchart of a method for implementing energy-saving control in a home base station environment in Embodiment 1 of the present invention. In this embodiment, the source base station sends an energy-saving control request to the target home base station, and the request is forwarded to the target through the mobility management entity (MME) of the core network For the home base station, the energy-saving control messages in this embodiment are all implemented based on the S1 interface, and the specific steps are as follows:

[0038] Step 201, the source base station sends an energy-saving control request message to the MME, and the message carries: message type, target base station information, source base station information, and energy-saving control request type;

[0039] The source base station may be a macro base station or a home base station;

[0040] The message type is used to distinguish the type of the current message.

[0041] The energy-s...

Embodiment 2

[0066] image 3 It is a flow chart of the method for implementing energy-saving control in the home base station environment in Embodiment 2 of the present invention. In this embodiment, the source base station sends an energy-saving control request to the target home base station, and the request is forwarded to the target home base station gateway through the MME, and then the target home base station The gateway forwards to the target Femtocell. In this embodiment, the energy-saving control messages are all implemented based on the S1 interface, and the specific steps are as follows:

[0067] Step 301, the source base station sends an energy-saving control request message to the MME, and the message carries: message type, target base station information, source base station information, and energy-saving control request type;

[0068] The source base station may be a macro base station or a home base station;

[0069] The message type is used to distinguish what the curre...

Embodiment 3

[0099] Figure 4 It is a flowchart of a method for implementing energy-saving control in a home base station environment in Embodiment 3 of the present invention. This embodiment is aimed at the scenario where the target home base station deletes the S1 interface when receiving a sleep request. The specific steps are as follows:

[0100] Sleep process:

[0101] Step 401, when the MME or the Femtocell gateway needs to notify the Femtocell to go into sleep mode, the MME or the Femtocell gateway sends a dormancy request to the target Femtocell;

[0102] The dormancy request is sent to the target home base station to be awakened through a RESET message of the S1 interface or newly added S1 interface signaling, which includes dormancy indication information;

[0103] Step 402, the target home base station performs a sleep operation after receiving the sleep request, and if the sleep operation is successful, the home base station deletes the S1 interface;

[0104] Wake up process: ...

Abstract

The invention discloses a method and device for energy-saving control in the home base station environment, which are used to solve the energy-saving control problem in the home base station environment. In the present invention, the source base station sends an energy-saving control request to the target home base station. The energy-saving control request includes: target base station information, source base station information, and the type of the energy-saving control request. After receiving the energy-saving control request, the target home base station executes the energy-saving control processing operation, And the result of the energy-saving control processing is sent to the source base station through an energy-saving control response. If the energy-saving control processing fails, the energy-saving control response further includes a failure reason and / or a waiting time. Through the interaction of related energy-saving control messages between the source base station and the target home base station, the present invention can timely realize the energy-saving control of the home base station, realize the dormancy or wake-up of the home base station, and achieve the purpose of effective energy saving of the network under the environment of the home base station.

Description

technical field [0001] The present invention relates to a wireless cellular communication system, more specifically, a method and device for energy-saving control in a home base station environment in a Long Term Evolution (LTE) mobile communication system. Background technique [0002] LTE 36300-800 describes that the LTE network is composed of EUTRAN (Evolved UTRAN) base station eNB (EvolvedNodeB) and evolved packet switching center (Evolved Packet Core, EPC), and the network is flat. The EUTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2. S1 and X2 are logical interfaces. One EPC can manage one or more eNBs, one eNB can also be controlled by multiple EPCs, and one eNB can manage one or more cells. One or several cells belong to one tracking area (Tracking Area, TA). At the same time, there are Femtocells in the LTE network. In order to meet the coverage requirements in public places, the combination ...
