Embodiment 1

[0052] When the home base station in this embodiment decides to enter the energy-saving state, it notifies the neighbor home base station of the energy-saving state information. Figure 4 The illustrated scenario where the home base station is distributed under the macro base station eNB is described as an example. The access attribute of the home base station HeNB A is a closed access mode, and the cell where it is located is a closed cell. The access of the home base station HeNB B in the neighboring cell The access attribute is a closed access mode or a hybrid access mode, and the cell where it is located is a closed cell or a hybrid cell. see Figure 5 The flow chart of the method for controlling the energy saving of the home base station is shown, the method includes the following steps:

[0053] Step S502: Home base station A measures and finds that the current load of the cell is very low or does not allocate any resources to serve the UE, and home base station A decid...

Embodiment 2

[0064] When the home base station in this embodiment decides to enter the energy-saving state, it notifies the macro base station of the energy-saving state information. In this embodiment, the Figure 4 The illustrated scenario where the home base station is distributed under the macro base station eNB is taken as an example for illustration, and the access attribute of the home base station HeNB A is a hybrid access mode or an open access mode. see Image 6 The flow chart of the method for controlling the energy saving of the home base station is shown, the method includes the following steps:

[0065] Step S602: Home base station A measures and finds that the current load of the cell is very low or does not allocate any resources to serve the UE, and home base station A decides to enter an energy-saving dormant state.

[0066]Step S604: In order to let neighboring cells know that it has entered the energy-saving mode, before entering the energy-saving mode, HNB A sends an ...

Embodiment 3

[0076] When the home base station in this embodiment decides to enter the energy-saving state, it notifies the macro base station of the energy-saving state information, and the UE wakes up the home base station through a PI instruction. This embodiment takes Figure 4 The scenario where the shown home base stations are distributed under the eNB of the macro base station is taken as an example to illustrate, see Figure 7 The flow chart of the method for controlling the energy saving of the home base station is shown, the method includes the following steps:

[0077] Step S702: the home base station A measures and finds that the current load of the cell is very low or does not allocate any resources to serve the UE, and the home base station A decides to enter an energy-saving dormant state.

[0078] Step S704: In order to be able to enter the dormant mode, the HNB A needs confirmation from the macro base station. The home base station A sends an energy-saving state request ...

Abstract

The invention discloses a method and system for controlling energy conservation of a Home (e) NodeB (H(e) NB), an H(e) NB and a network element. The method comprises the following steps that: an H(e) NB determines to enter an energy-saving sleeping state; the H(e) NB sends energy-saving state information to an associated network element and enters the energy-saving sleeping state, wherein the energy-saving state information includes an identity of a cell that the H(e) NB is located at and an access mode of the H(e) NB; the associated network element preserves the energy-saving state information; when it is determined that a user wants to be switched to the cell that the H(e) NB is located at, the H(e) NB is activated according to the energy-saving state information. According to the invention, a problem of lots of power consumption of an H(e) NB is solved and it is beneficial for energy conservation and environmental protection. Moreover, the utilization of the method dose not influence normal switching of a user to a cell that the H(e) NB is located at, thereby not influencing user experience.

Description

technical field [0001] The present invention relates to the field of wireless cellular communication, in particular to a method and system for controlling energy saving of a home base station, a home base station and a network element. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) network is composed of an evolved base station (Evolved NodeB, eNB) and an EPC (Evolved Packet Core, evolved packet switching center) in E-UTRAN (Evolved UTRAN, evolved UTRAN), and the network is flat. Among them, the E-UTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2, and 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. The EPC is composed of MME (Mobility Management Entity, mobile management unit), SGW (Serving Gateway, serving gateway), and PGW (Packet Data Network Gateway, pack...
