Detailed Description
In practical application, the coverage compensation neighboring cell may obtain the coverage location information of the energy-saving cell from a cell dormancy REQUEST message, an X2 establishment REQUEST (SETUP REQUEST), an X2 establishment RESPONSE (SETUP RESPONSE), or a base station CONFIGURATION UPDATE (ENB CONFIGURATION UPDATE) message sent by the energy-saving cell. The coverage location information may include information that the transmission point of the cell can accurately describe the coverage area and the geographic location of the cell via dimensional coordinates, a coverage radius, a sector direction and a width (if a sector cell), and the like.
The energy-saving cell can acquire the coverage compensation information of the coverage compensation neighboring cell from a cell dormancy confirmation message, an X2SETUP request, an X2SETUP RESPONSE or an ENB CONFIGURATION UPDATE message sent by the coverage compensation neighboring cell. The coverage compensation information can be coverage position information which represents an accurate coverage area and a geographical position which can be currently covered by a coverage compensation adjacent cell; or may be relative information expressed in the form of a percentage or the like, which indicates the range in which the coverage of the coverage compensation neighboring cell is expanded with respect to the normal state when no compensation is provided.
As shown in fig. 1 and fig. 2, when an energy-saving cell needs to enter a sleep state, a cell sleep request message is sent to a base station to which a coverage compensation neighboring cell belongs. The cell dormancy request message may carry information about the current coverage location of the energy-saving cell. Actually, when the energy-saving cell needs to enter the dormant state, the energy-saving cell can judge according to the known coverage compensation information of the coverage compensation neighboring cell, and if the coverage compensation neighboring cell can currently cover the coverage area of the energy-saving cell, the energy-saving cell can automatically enter the dormant state without sending a cell dormancy request message to the coverage compensation neighboring cell; otherwise, the cell dormancy request message needs to be sent to the coverage compensation neighbor cell.
After receiving the cell dormancy request message, the base station to which the coverage compensation neighbor cell belongs judges whether the coverage compensation neighbor cell can cover the currently covered area of the energy-saving cell or whether the coverage range of the coverage compensation neighbor cell can be expanded to the currently covered area of the energy-saving cell according to the coverage position information of the energy-saving cell carried in the message, if so, a cell dormancy confirmation message is replied, otherwise, a cell dormancy rejection message is replied. And, the time information may be carried in the cell dormancy acknowledgement message. And, when the cell dormancy request message of the energy-saving cell receives the confirmation of the coverage compensation neighbor cell (i.e. the cell dormancy confirmation message is replied), the coverage compensation neighbor cell supports the communication of the area where the dormant energy-saving cell is located in the subsequent communication process.
After receiving the cell dormancy confirmation message, if the cell dormancy confirmation message carries time information, the energy-saving cell is closed after waiting for the time corresponding to the time information; otherwise, the energy-saving cell may be immediately turned off.
In addition, the energy-saving cell gives up the dormancy after receiving the cell dormancy rejection message, and continues to operate normally.
Furthermore, when the load of the coverage compensation neighboring cell is high and it is desired that the energy-saving cell(s) that have entered the dormant state help to share the load, the coverage compensation neighboring cell may determine to which base station or base stations the energy-saving cells belong to send a cell activation request message according to the stored coverage location information of the energy-saving cells and the terminal location distribution information that can be measured, so as to activate the corresponding energy-saving cells.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings.

The current load of the energy-saving Cell C1 is 0, and the energy-saving Cell C1 needs to enter a dormant state, and sends a Cell dormancy request message to the base station to which the coverage compensation neighboring Cell a belongs. The cell dormancy request message carries current coverage location information of the energy-saving cell, and the coverage location information comprises information that the emission point of the cell can accurately describe the coverage area and the geographic location of the cell through dimension coordinates, coverage radius, sector direction, width (if the cell is a sector cell) and the like.
After receiving the Cell dormancy request message, the base station to which the coverage compensation neighbor Cell Cel A belongs judges that the coverage compensation neighbor Cell Cel A cannot cover the area currently covered by the energy-saving Cell C1 at present according to the coverage position information of the energy-saving Cell carried in the message, but may extend the coverage to the area currently covered by energy saving cell C1, then reply to the cell dormancy acknowledgement message, the cell dormancy acknowledgement message may also carry time information, where the coverage compensation information is carried after the coverage compensation neighboring cell expands the coverage range (the coverage compensation information may be coverage position information indicating an accurate coverage area and a geographical position that the coverage compensation neighboring cell can currently cover, or may also be relative information expressed in a percentage form or the like indicating a range in which the coverage of the coverage compensation neighboring cell expands relative to a normal state when no compensation is provided).

The cell dormancy request message carries current coverage location information of the energy-saving cell, and the coverage location information comprises information that the emission point of the cell can accurately describe the coverage area and the geographic location of the cell through dimension coordinates, coverage radius, sector direction, width (if the cell is a sector cell) and the like.
After receiving the Cell dormancy request message, the base station to which the coverage compensation neighbor Cell a belongs judges that the coverage compensation neighbor Cell a cannot currently cover the currently covered area of the energy-saving Cell C2 according to the coverage position information of the energy-saving Cell carried in the Cell dormancy request message, but the coverage of the coverage compensating neighbor cell may be extended to the area currently covered by energy saving cell C2, whereupon a cell dormancy acknowledgement message is returned, the cell dormancy confirmation message may also carry time information, where the coverage compensation information after the coverage extension is carried (the coverage compensation information may be coverage position information indicating an accurate coverage area and a geographical position that the coverage compensation neighboring cell can currently cover, or may also be relative information expressed in a percentage form or the like indicating a range in which the coverage of the coverage compensation neighboring cell is extended with respect to a normal state when no compensation is provided).
If the Cell dormancy confirmation message replied to the energy-saving Cell C2 by the coverage compensation neighboring Cell a carries time information, waiting for the time corresponding to the time information, and then expanding the coverage range of the coverage compensation neighboring Cell to the range indicated by the coverage compensation information in the Cell dormancy confirmation message (here, expanding to the 100% position in fig. 5); otherwise, the coverage of the coverage compensation neighbor cell can be immediately expanded.
After receiving the cell dormancy acknowledgement message, the energy-saving cell C2, if the cell dormancy acknowledgement message carries time information, then waits for the time corresponding to the time information and then closes; otherwise, it may be immediately turned off.
The coverage compensation neighbor Cell a sends an ENB configuration update message to its neighbors C1, C3, etc., where the coverage compensation information is carried to notify of the new coverage.
The energy saving Cell C2 sends an ENB configuration update message to its neighbors Cell a, C1, C3, etc. to inform the energy saving Cell C2 that it has entered the dormant state.
The third embodiment described in conjunction with fig. 1 and 5 is as follows:
cell a is a coverage compensation neighbor Cell, currently in a compensation state (here, expanded to 100% of the position in fig. 5); c1, C2 and C3 are energy-saving cells, C1 and C2 are currently in a dormant state, and C3 is currently in a normal state.
The current load of the energy-saving Cell C3 is 0, and the energy-saving Cell C3 needs to enter a dormant state, and determines that the coverage compensation neighboring Cell can currently cover the coverage area of the energy-saving Cell C3 according to the known coverage compensation information of the coverage compensation neighboring Cell a.
The energy-saving Cell C3 enters a dormant state by itself, and does not send a Cell dormancy request message to the base station to which the coverage compensation neighbor Cell A belongs.
The energy saving Cell C3 sends an ENB configuration update message to its neighbors Cell a, C1, C2, etc. to inform the energy saving Cell C3 that it has entered the dormant state.
The fourth embodiment described in conjunction with fig. 2 and 5 is as follows:
cell a is a coverage compensation neighbor Cell, currently in a compensation state (here, expanded to 50% of the position in fig. 5); c1, C2 and C3 are energy-saving cells, C1 is in a dormant state currently, and C2 and C3 are in a normal state currently.
The current load of the energy-saving Cell C3 is 0, and the energy-saving Cell C3 needs to enter a dormant state, and determines that the coverage compensation neighboring Cell cannot currently cover the coverage area of the energy-saving Cell C3 according to the known coverage compensation information of the coverage compensation neighboring Cell a.
And the energy-saving Cell C3 sends a Cell dormancy request message to the base station of the coverage compensation neighbor Cell CelA. The cell dormancy request message carries current coverage location information of the energy-saving cell, and the coverage location information comprises information that the emission point of the cell can accurately describe the coverage area and the geographic location of the cell through dimension coordinates, coverage radius, sector direction, width (if the cell is a sector cell) and the like.
After receiving the Cell dormancy request message, the base station to which the coverage compensation neighbor Cell a belongs judges that the coverage compensation neighbor Cell a cannot currently cover the currently covered area of the energy-saving Cell C3 and cannot currently expand the coverage range of the coverage compensation neighbor Cell according to the coverage position information of the energy-saving Cell carried in the Cell dormancy request message, and then replies a Cell dormancy rejection message.
After receiving the cell dormancy rejection message, the energy saving cell C3 temporarily abandons dormancy and continues normal operation.
The embodiment five described in conjunction with fig. 3, 4 and 5 is as follows:
cell a is a coverage compensation neighbor Cell, currently in a compensation state (here, expanded to 100% of the position in fig. 5); c1, C2 and C3 are energy-saving cells and are all in a dormant state currently.
And judging that more active terminals near C2 and C3 are currently available according to the stored coverage position information of each energy-saving Cell and the measurable terminal position distribution information.
And the coverage compensation neighbor Cell A sends a Cell activation request message to the base stations of the dormant energy-saving cells C2 and C3.
And after receiving the cell activation request message, the base stations of the energy-saving cells C2 and C3 activate the energy-saving cells indicated in the cell activation request message, if the activation can be successfully performed, replying a cell activation response message, and if not, replying a cell activation failure message.
If the coverage compensation neighboring Cell a receives the Cell activation response message indicating that the energy saving cells C2 and C3 are successfully activated, it may be further determined whether the coverage of itself may be reduced (to the 50% position in fig. 5), and if so, the coverage may be reduced.
If the energy-saving cell C2 is successfully activated, an ENBCONFIGURATION UPDATE message is sent to the adjacent cells C1, C3 and the like to inform the energy-saving cell C2 that the energy-saving cell C2 enters a normal working state; if the energy-saving cell C3 is successfully activated, an ENB configuration update message is sent to its neighboring cells C1, C2, etc. to inform the energy-saving cell C3 that it has entered a normal operating state.
