Mobile communication technology is increasingly deployed and applied in its open network system architecture, and network operators are increasingly concerned about energy saving technology of mobile communication systems with popularization of mobile communication technology, global warming effect and climate change. For energy saving technologies, the third generation partnership project (3GPP) protocol based on 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 research and development project started by the 3GPP in recent years, energy saving technology is standardized in the LTE system, and the LTE network manager reduces energy consumption of the network, protects the environment, and reduces operation and maintenance costs of operators through energy saving measures such as closing an eNB or closing a cell.
At present, a method for implementing energy saving state management in an LTE system is as follows: performing interaction of instructions and notifications between the cell performing energy saving state setting and the eNB in which the adjacent cell is located through an X2 interface signaling, specifically: the eNB sets a cell to enter an energy-saving activation state according to the network service information and the energy-saving strategy, informs a network manager and an adjacent eNB that the cell enters the energy-saving activation state, selects an energy-saving compensation cell for the cell in the energy-saving activation state by the network manager, and sends an energy-saving compensation activation instruction to the eNB in which the selected energy-saving compensation cell is located; similarly, when a cell in the energy saving activated state of the eNB is to be restored to the normal state, the eNB may notify the network manager that the cell enters the energy saving deactivated state.
However, the eNB does not provide two types of notifications of energy saving compensation activation and energy saving compensation deactivation for the neighboring eNB currently, so that when a certain cell a needs to perform load balancing or other service operations, because it is unknown that its neighboring cell is in an energy saving compensation state, the cell a may use the neighboring cell in the energy saving compensation state as a candidate cell for service, and if the cell in the energy saving compensation state is finally selected to provide service operations for the cell a, a situation that the operations cannot be performed normally due to the energy saving state is present, or a situation that the selected cell needs to be activated before the normal operations occur, so that a certain influence may be caused on the operations of the system, thereby reducing the energy saving efficiency of the system, the stability of the system, and affecting the user experience.
