Problems solved by technology

[0004] However, eNB currently does not provide two types of notifications for energy saving compensation activation and energy saving compensation deactivation to neighboring eNBs. In this way, when a certain cell A needs to perform load balancing or other service operations, it does not know that its neighboring cells are in the state of energy saving compensation , the cell A may use the neighboring cell in the energy-saving compensation state as a service candidate cell. If the cell in the energy-saving compensation state is finally selected to provide service operations for cell A, the operation may not be performed normally due to the energy-saving state. In some cases, or there is a situation where the selected cell needs to be activated before it can operate normally, this will have a certain impact on the operation of the system, thereby reducing the energy saving efficiency of the system, the stability of the system, and affecting the user experience

Embodiment Construction

[0028] The basic idea of ​​the present invention is: when an eNB manages a cell in an energy-saving compensation activation state and / or in an energy-saving compensation deactivation state, the eNB sends an energy-saving state notice of the self-managed cell to a neighboring eNB.

[0029] Specifically, when a cell in the cell managed by the eNB enters the energy saving compensation activation state, the eNB sends a notification to the neighboring eNB that the cell it manages is in the energy saving compensation activation state; and / or when a cell in the eNB management cell enters the energy saving compensation deactivation In the state, the eNB sends a notification to the neighboring eNB that the cell it manages is in the energy saving compensation deactivation state;

[0030] Here, the sending is to first write the notification of the energy saving state according to the format of the X2 interface signaling, and then send the written notification of the energy saving state; t...

Abstract

The invention discloses a notification method of an energy-saving state. According to the method, an evolution base station (eNB) transmits an energy-saving state notice of self-managed cells to an adjacent eNB when confirming some of the self-managed cells enter an energy-saving compensation activation state and / or some of the self-managed cells enter an energy-saving compensation deactivation state. And meanwhile, the invention also discloses the eNB. By adopting the method disclosed by the invention, energy-saving efficiency of a system can be improved, and stability of the system is also improved.

Description

technical field [0001] The present invention relates to energy-saving technology in a mobile communication system, in particular to an energy-saving state notification method and an evolved base station (eNB). Background technique [0002] Mobile communication technology has been deployed and applied more and more with its open network system architecture. With the popularization of mobile communication technology, as well as the global greenhouse effect and climate change, network operators are paying more and more attention to the energy-saving technology of mobile communication systems . For energy-saving technology, the 3rd Generation Partnership Project (3GPP) protocol based on the third generation (3G) mobile communication technology defines four cell energy-saving states: energy-saving activation, energy-saving deactivation, energy-saving compensation activation and energy-saving compensation deactivation. The Long-Term Evolution (LTE) project is a new technology res...
