It should be noted that the energy-saving state checking process may be an inquiry process initiated before cell energy-saving compensation, and the purpose is to inquire whether each cell in the above-mentioned group of cells can switch to the target state under the first cell state combination.

It should also be noted that the above-mentioned second cell may be any one of the remaining cells in the above-mentioned group of cells except the first cell, and may also refer to all the cells in the remaining cells.

In this embodiment of the present invention, a group of cells is pre-configured with energy-saving cell combination information, and the energy-saving cell combination information includes at least one cell state combination. When the first cell is about to initiate an energy-saving Combination selects a suitable cell state combination, and inquires whether other cells can switch to the target state under the cell state combination according to the indication of the cell state combination, providing an effective inquiry method suitable for various cell energy-saving compensation scenarios , reducing the blindness of existing inquiry methods.

Optionally, as an embodiment, in the case that all other cells in a group of cells except the first cell can switch to the target state of other cells under the first cell state combination, the first base station sets the first The cell is handed over to the target state of the first cell under the first cell state combination.

Before the first base station switches the first cell to the target state of the first cell under the first cell state combination, the first base station sends a state switching inquiry message to the OAM device (Operation Administration and Maintenance, operation management and maintenance) device, when the OAM device allows the first When the base station switches the first cell to the target state of the first cell under the first cell state combination, the first base station switches the first cell to the target state of the first cell under the first cell state combination, otherwise the first base station does not Execute the switch operation.

It should be understood that the above-mentioned normal state, closed state or compensation state are all states of a cell, wherein the normal state means that the cell neither enters the closed state nor compensates for other cells; the closed state means that the cell enters an energy-saving state and does not The UE in the cell provides services; the compensation state means that the cell expands the service range (coverage area) to compensate part or all of the service area of the cell entering the closed state.

It should be noted that the embodiment of the present invention does not limit the specific form of the energy-saving cell combination information, for example, the form of Table 1 may be used.

Table 1: A form of energy-saving cell combination information

composite index Cell 1 Cell 2 Cell 3 Cell 4 District 5 0 normal status normal status normal status normal status normal status 1 Disabled Disabled compensation status compensation status compensation status 2 Disabled normal status normal status compensation status compensation status

The above-mentioned group of cells may correspond to cells 1 to 5 in Table 1, and Table 1 shows 3 cell state combinations (that is, rows 2 to 4 in Table 1), and each cell state combination stores cells 1 to 5. The target state of cell 5 under this cell state combination. In fact, each cell state combination corresponds to a possible energy-saving compensation mode of the above-mentioned group of cells. For example, in the cell state combination corresponding to the combination index 1, cells 1 and 2 are in the off state, and Compensation state means that under the energy-saving compensation mode corresponding to combination index 1, cell 1 and cell 2 enter the energy-saving state, and cells 3 to 5 increase their respective coverage areas to cover the service areas of cell 1 and cell 2; similarly, in In the energy-saving compensation mode corresponding to combination index 2, cell 1 enters an energy-saving state, and cell 4 and cell 5 provide compensation for it.

It should be noted that Table 1 is only an implementation form of energy-saving cell combination information, and any other equivalent form may be used in practice, such as storing cell states in an array.

It should be noted that the cells in the above group of cells may share a base station, or may correspond to their own base stations, or may be in any other corresponding form, which is not specifically limited in the implementation of the present invention. Specifically, when the first cell and the second cell are controlled by the same base station, the first base station and the second base station are the same base station. It should also be noted that, for the convenience of description, the steps performed by a certain cell in the embodiment of the present invention can be understood as the steps performed by the control base station of the cell, for example, cell 1 asks whether cell 2 can switch to a certain state , actually means that the control base station of cell 1 inquires the control base station of cell 2 whether cell 2 can switch to the certain state.

In practice, one cell state combination or multiple cell state combinations may be pre-configured in the energy-saving cell combination information, which is not specifically limited in this embodiment of the present invention. However, when there is only one cell state combination, the combination index may not be configured, and when there are multiple cell state combinations, optionally, the energy-saving cell combination information may include at least one cell state combination and at least one cell state At least one combination index of the combination, and the status check message may include the first combination index used to identify the first cell status combination, and before the first base station selects the second cell according to the preconfigured energy-saving cell combination information, it may also include: A base station selects a first cell state combination from at least one cell state combination.

Specifically, as shown in Table 1, a total of 3 cell state combinations are included, so a combination index (0, 1 and 2 in Table 1) is pre-configured for each cell state combination. Assuming that the first cell is cell 2 in Table 1, when the load of cell 2 is low and it is desired to enter the energy-saving state, the energy-saving state check process can be initiated through the control base station of cell 2 (hereinafter referred to as base station 2). , base station 2 needs to select an appropriate cell state combination from Table 1, and finds that only the cell state combination corresponding to combination index 2 can make cell 2 enter the closed state, so select the cell state combination corresponding to combination index 2 as the above-mentioned first cell state combination .

Then, cell 2 initiates the above-mentioned energy-saving status check process, and base station 2 sends a status check message to the control base station of cell 3 (hereinafter referred to as base station 3, which may be the same base station as base station 2), and the status check message is used to ask whether cell 3 can Switch to the target state of cell 3 under combination index 2, that is, the compensation state. Specifically, the state check message may carry the combination index 2, so that the base station 3 selects the target state of the cell 3 under the combination index 2 according to the combination index 2. Apparently, if the energy-saving cell combination information includes only one cell status combination, the status check message does not need to carry the index.

Optionally, as another embodiment, the status check message may further include a root identifier used to indicate that the first cell is an initiating cell of the energy saving status check process.

For example, if "cell 1" is included in the status check message, it means that the energy-saving state check process is initiated by cell 1 (of course, here, cell 1 is regarded as the logical execution subject, and in practice, the initiator of the energy-saving state check process is still cell 1 control base).

Optionally, as another embodiment, the method in FIG. 2 may further include: the first base station receiving a first status check success message sent by the control base station of the third cell, where the first status check success message is used to indicate that the above group of cells All other cells except the first cell can be switched to the target state of other cells under the first cell state combination.

Specifically, the above-mentioned third cell may be any cell in the above-mentioned group of cells, but the third cell must be able to know that the above-mentioned other cells can switch to the target state under the first cell state combination. However, this embodiment of the present invention does not specifically limit how the third cell learns whether the other cells can switch to the target state under the first cell state combination. Taking a group of cells shown in Table 1 as an example, assuming that the first cell is cell 1, the first cell state combination is the cell state combination corresponding to the combination index 2. The above-mentioned energy-saving state checking process can be carried out in a sequential manner, that is, cell 1 inquires whether cell 2 can be switched to the off state, and when cell 2 determines that it can switch to the off state, cell 2 inquires whether cell 3 can switch to the compensation state, so Until cell 5 determines that it can switch to the compensation state, cell 5 finds that the next query target returns to the initiating cell (cell 1). At this time, cell 5 is the above-mentioned third cell. The above-mentioned first status check success message is sent. Of course, the above inquiry process can also use not inquiring about the cells whose target state is in the normal state under the first cell state combination, and when a certain cell finds that the target state of the next cell is in the normal state, it directly skips the cell and continues to inquire.

To give another example, cell 1 in Table 1 is going to initiate a cell state combination with a combination index of 2. Cell 1 selects a cell from among cell 4 and cell 5 (a cell whose target state is not normal) to make an inquiry. For example, cell 5 is selected. , after cell 5 determines that it can switch to the compensation state, it selects from the remaining cells whose target state is abnormal, leaving only cell 4, so it initiates a status check message to cell 4, and carries cell 5 in the status check message Determine the identification information that can be switched to the target state. After receiving the status check message, cell 4 determines that cell 4 can switch to the compensation state, and finds that the rest of the cells have been checked through the above identification information, then report to cell 1 (such as according to the above-mentioned Root ID) sends the above-mentioned first status check success message.

Optionally, as another embodiment, the method in FIG. 2 may further include: the first base station receives a first status update message sent by the second base station, and the first status update message is used to instruct the first base station to switch the first cell to the second base station. The target state of a cell under the first cell state combination.

Specifically, when all the cells in a group of cells can be switched to the target state, one of the cells can initiate a state update message, for example, using the above-mentioned way of inquiring one by one, when the last cell determines that it can switch to the target state state, the cell initiates a state update in the reverse order of the one-by-one inquiry, and updates the state of each cell in turn until the first cell mentioned above.

Optionally, as another embodiment, when the fourth cell in a group of cells cannot be handed over to a cell in the target state of the fourth cell under the first cell state combination, the method in FIG. 2 may further include: the first base station The first status check failure message sent by the control base station of the fourth cell is received; the first base station ends the energy saving status check process.

The above-mentioned fourth cell may be any cell in the above-mentioned group of cells except the first cell. Specifically, if the first cell simultaneously sends a status check message to other cells in the group of cells except the first cell, when When a certain cell in the remaining cells cannot be switched to the target state, send the above-mentioned first state check failure message to the first cell; In the target state, use the root identifier in the status check message to send the above-mentioned first status check failure message to the first cell. As long as the first base station receives a message that the status check fails, the energy-saving status check process can be ended. The embodiment of the present invention does not limit the specific manner of ending the energy-saving state checking process, which may be that the first base station does not perform any operation, or the first base station notifies other cells that the energy-saving state check fails.

Optionally, as another embodiment, the second cell is the remaining cells in a group of cells except for the first cell, and the method in FIG. 2 may further include: the first base station respectively receives control of each cell in the remaining cells The second status check success message sent by the base station, the second status check success message is used to indicate that each cell can switch to the target status of each cell under the first cell status combination.

Specifically, the first base station sends a state check message to the control base stations corresponding to all remaining cells, and when each cell in all remaining cells determines that it can switch to the target state, it directly replies to the first base station with a second state check success message, without Root ID.

Optionally, as another embodiment, when the fifth cell among the remaining cells cannot be switched to the target state of the fifth cell under the first cell state combination, the method in FIG. 2 may further include: the first base station receives the fifth The second state check failure message sent by the control base station of the cell; the first base station ends the energy saving state check process.

Specifically, in this embodiment, since the first base station directly sends a status check message to the fifth cell, the fifth cell can directly reply to the first base station that the status check failed without a root identifier.

Optionally, as another embodiment, the method in FIG. 2 further includes: the first base station receiving a second status check failure message sent by the control base station of the fifth cell; the first base station ending the energy saving status check process, where the fifth cell is A cell other than the first cell in the above group of cells.

Optionally, as another embodiment, the method in FIG. 2 may further include: the first base station sends a status update message to the control base stations of other cells according to the energy-saving cell combination information, and the status update message is used to instruct the control base stations of other cells to respectively The state of other cells is switched to the target state of other cells under the first cell state combination.

Specifically, the first base station sends a status update message to all remaining cells in the group of cells, and the message may include the first combination index and/or update time. The update time is used to indicate the time when the control base station of the other cell switches the state of the other cell to the target state of the other cell under the first cell state combination. In this way, when the remaining cells receive the state update message, they can determine the target state according to the first combination index (this index is not needed when there is only one cell state combination), and can also determine the time to switch to the target state according to the update time.

The method for cell energy saving compensation according to the embodiment of the present invention has been described in detail from the perspective of the first cell (initiating cell) in conjunction with Fig. 1 and Fig. 2 above. A method for cell energy saving compensation according to an embodiment of the present invention is described from the perspective of the present invention.

It should be understood that the interaction between the first cell and the second cell and related features and functions described on the second cell side correspond to the description on the first cell side, and repeated descriptions are appropriately omitted for brevity.

Fig. 3 is a schematic flowchart of a method for cell energy saving compensation according to another embodiment of the present invention. The method in FIG. 3 may be executed by the control base station of the second cell.

It should be understood that when the energy-saving cell combination information includes multiple cell state combinations, a combination index may be carried in the above-mentioned first state check message to identify the above-mentioned first cell state combination. When the energy-saving cell combination information includes only one cell state combination, this identifier is not required.

320. The second base station determines the first target state according to the first state check message.

330. The second base station determines whether the second cell can be switched to the first target state.

It should be understood that, after determining the first target state, the second base station may determine whether the second cell can switch to the first target state according to the load state of the second cell. If the target state of the second cell is the closed state, the second cell determines the number of UEs in the cell, and when the UE is less than a certain threshold, it is determined that the target state of the second cell can be switched to the closed state; or, the target state of the second cell is the compensation state , the second cell determines whether the coverage area can be increased according to its own load capacity.

In this embodiment of the present invention, a group of cells is pre-configured with energy-saving cell combination information, and the energy-saving cell combination information includes at least one cell state combination. A cell state combination determines its target state, thereby providing an effective query method applicable to various cell energy-saving compensation scenarios, and reducing the blindness of the existing query methods.

The embodiment of the present invention does not limit the specific method for the second base station to determine whether there are still unchecked cells. For example, the following method may be used:

Mode 1, the energy-saving cell combination information includes arrangement information used to indicate the order of a group of cells, and the energy-saving state checking process checks whether a group of cells can be switched to the first cell state combination in sequence according to the order of arrangement information. The second base station determines whether there are still unchecked cells in a group of cells may include: the second base station determines whether the next first cell to be inspected is an initiating cell according to the arrangement information and the root identifier, wherein the first cell to be inspected In order, the remaining cells between the second cell and the initiating cell, or the first cell to be checked is a cell whose target state under the first cell state combination is not a normal state in the remaining cells; Selecting the third cell from the uninspected cells includes: when the next first cell to be inspected is not the originating cell, the second base station selects the next first cell to be inspected as the third cell.

Combined with the example in Table 1, it is still assumed that cell 3 is the initiating cell, and cell 3 selects an unchecked cell from cells 1, 2, 4, and 5. For example, cell 5 is selected. When cell 5 can be switched to the target state, the remaining Select one of the cells 1, 2, and 4 (such as cell 2) to send a status check message, and carry cell 5 OK in the message to indicate that the check of cell 5 is completed, and cell 4 receives the status check message and confirms that it can switch to the target In the state, according to the "OK" mark, it is determined that cells 1 and 2 are unchecked cells, and similarly select one of cells 1 or 2 to send a status check message, and carry the mark of cell 4 OK.

The message carries "root identity=cell 1" and "combination index=1". Cell 1 is the cell that initiates the energy-saving status check process. Cell 1 selects a cell from all undetected cells to send a status check message. This message and subsequent status check messages can carry the identifier of "Cell 1: OK", but It is also possible not to carry the identifier of "cell 1: OK" (by default, the initiating cell can be switched to the target state).

602. The cell 3 determines whether it can switch to the target state.

Cell 3 determines that its target state is the compensation state according to the combination index 1, and cell 3 determines whether it can switch to the compensation state according to its own load situation: when it cannot switch to the compensation state, perform step 603a; when it can switch to the compensation state, according to "Cell 1: OK", it is determined that cells 2, 4, and 5 are unchecked cells, and cell 4 is selected as the next cell to be checked, and step 603b is executed.

603a. Cell 3 sends a status check failure message to cell 1.

Before sending the message, cell 3 determines cell 1 as the originating cell according to the root identifier.

603b. Cell 3 sends a status check message to cell 4.

The message carries information such as "combination index=1", "root identifier=cell 1", "cell 1, 3: OK".

Steps 604-609a are similar to the previous process and will not be repeated here.

609b. Cell 5 determines that there is no unchecked cell, and sends a status check message (or a status check success message) to the root cell. The message may carry identifiers of all cells capable of switching to the target state.

610. Community 1 makes a decision.

Cell 1 makes decisions based on various received messages. When cell 1 receives a status check failure message sent by any cell from cell 2 to cell 5, it can end the energy saving status check process. When cell 1 receives a status check message sent by a certain cell, and the status check message carries the identifier of "cell 1, 2, 3, 4, 5: OK", execute steps 611-614.

611-614: Send status update messages to cells 2 to 5, which are similar to steps 411-414 and will not be repeated here.

It should be understood that the status update manner in this embodiment of the present invention may also be performed in the manner shown in FIG. 5 . It should also be understood that in combination index 1, the target states of all cells are abnormal states (shutdown state or compensation state), so each cell will receive a state check message. However, when under other combination indexes, such as combination index 2, cell 2 and cell 3 are in the normal state, they can be switched to the target state by default, and there is no need to receive a status check message. And the target state is the cells in the abnormal state to select the cell to be checked. After all the cells in the abnormal state have been detected, a status check success message can be sent to cell 1.

Further, in the method of Fig. 4 to Fig. 6, when cell 2 to cell 5 fail the state check, it is also possible not to send a state check failure message to cell 1, and continue to perform the next check. When all the checks of the cells are completed, the last The cell will return the inspection results of all cells to the initiating cell, and the initiating cell will make a decision after analyzing the results. For example, if the result shows that there are cells that failed to switch to the target state, the energy-saving state inspection process will end; or cell 2 to cell 5 can switch to the target state, then execute the state update process.

In the embodiment of the present invention, the same energy-saving cell combination information is preset for the cells in the energy-saving compensation combination, and then each cell in the cell combination is inquired according to the combination information to determine whether it can switch to the preset target status, thus providing an effective inquiry process and reducing the blindness of inquiry methods in energy-saving compensation scenarios.

Fig. 7 is a flowchart of a method for cell energy saving compensation according to an embodiment of the present invention. The difference between the method in Fig. 7 and the method in Fig. 4-Fig. 6 is that the energy-saving status checking process does not adopt the method of inquiring sequentially, but the status checking messages are uniformly sent from cell 1 to cell 2 to cell 5 (separately, simultaneously, or simultaneously) Or any sending method, which is not specifically limited in the present invention), cell 2 to cell 5 directly reply to cell 1 after determining whether they can switch to the target state.

701. Cell 1 sends a status check message to cell 2.

The message carries "combination index=1".

702. The cell 2 determines whether it can switch to the target state.

Cell 2 determines that its target state is the off state according to the combination index=1, and determines whether it can be switched to the off state according to its own load condition.

703. Cell 2 replies to cell 1 with a status check result.

When cell 2 can be switched to the off state, the reply is successful; if not, the reply fails.

Steps 704-712 are similar to the above steps, and for the convenience of description, details are not repeated here. It should be noted that, the embodiment of the present invention does not limit the sequence of interaction between cell 1 and other cells. It should also be noted that, when there is a cell in a normal state among the cells 2 to 5, the status check message may not be sent to this cell. For example, when the combination index selected by cell 1 is 2, the status check message may only be sent to cell 4 and cell 5 .

713. Community 1 makes a decision.

Cell 1 makes decisions based on various received messages. When receiving a failure message sent by a cell in Cell 2 to Cell 5, it can be determined that the energy saving status check process has failed; , execute steps 714-717.

714-717, similar to 411-414, will not be repeated here.
