Area of A). The base station B~the base station G respectively determines whether it can provide compensation for the cell A according to the actual situation (such as the load of the respective cell, etc.), and sends a response message to the base station A. When the base station A determines that both the cell B and the cell G can enter the compensation state, the base station B is notified of the status update, and then the cell A is turned off. The base station B~the base station G respectively controls the cell B~cell G to enter the compensation state (after the energy saving compensation in Fig. 1, the cell B~cell G expands the coverage area to cover the cell A).

2 is a schematic flowchart of a method for cell energy saving compensation according to an embodiment of the present invention. The method of Figure 2 can be performed by a first base station, which is a control base station of the first cell.

The first base station selects a second cell according to the pre-configured energy-saving cell combination information, where the first base station is the control base station of the first cell, and the energy-saving cell combination information is used to indicate At least one cell state combination of a group of cells including a first cell and a second cell, each cell state combination in at least one cell state combination including a target of each cell in a group of cells under each cell state combination Status, target status is normal, closed or compensated.

The first base station sends a status check message to the second base station, where the second base station is the control base station of the second cell, and the status check message is used to query whether the second cell can switch to the second cell in the at least one cell state combination. The target state under the first cell state combination.

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

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

In the embodiment of the present invention, the set of cells is pre-configured with the energy-saving cell combination information, and the energy-saving cell combination information includes at least one cell state combination, and the first cell may be configured according to the pre-configured at least one cell state when preparing to initiate the energy-saving state check process. Combining and selecting suitable cell state combinations, and inquiring 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 query mode suitable for various cell energy saving compensation scenarios , reducing the blindness of existing inquiry methods.

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

Before the first cell switches the first cell to the target state of the first cell in the first cell state combination, the first base station sends a state switching inquiry message to the 0AM device (Operation Administration and Maintenance), when the device allows the first When the base station switches the first cell to the target state of the first cell in the first cell state combination, the first base station switches the first cell to the target state of the first cell in the first cell state combination, otherwise the first base station does not Perform this switching operation.

It should be understood that the normal state, the closed state, or the compensated state is a cell state, where the normal state means that the cell does not enter the closed state or compensates for other cells; the closed state refers to the cell entering the energy-saving state, which is incorrect. The UE in the cell provides the service; the compensation status refers to the cell expanding the service range (coverage area) to compensate for part or all of the service area of the cell entering the closed state.

It should be noted that, in the embodiment of the present invention, the specific form of the energy-saving cell combination information is not limited. For example, the form of Table 1 may be adopted.

Table 1: A form of combined information of energy-saving cells

The foregoing group of cells may correspond to the cell 1 to the cell 5 in Table 1, and Table 1 shows three cell state combinations (ie, 2 to 4 rows of Table 1), and each cell state combination stores the cell 1~ The target state of the cell 5 under the combination of the cell states. In fact, each cell state combination corresponds to a possible energy saving compensation mode of the foregoing group of cells. For example, in the cell state combination corresponding to the combination index 1, the cell 1 and the cell 2 are in a closed state, and the cell 3 to the cell 5 are in a state. The compensation state indicates that the cell 1 and the cell 2 enter the energy-saving state in the energy-saving compensation mode corresponding to the combination index 1, and the cell 3 to the cell 5 increase the respective coverage areas to cover the service areas of the cell 1 and the cell 2; similarly, In the energy-saving compensation mode corresponding to the combined index 2, the cell 1 enters a power-saving state, and the cell 4 and the cell 5 provide compensation thereto.

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

It should be noted that the cells in the foregoing group of cells may be a common base station, or may be corresponding to each The base station may be 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 be noted that, for convenience of description, the steps performed by a certain cell in the embodiment of the present invention can be understood as steps performed by the control base station of the cell, for example, the cell 1 queries whether the cell 2 can switch to a certain state. In practice, it means that the control base station of the cell 1 asks whether the control base station cell 2 of the cell 2 can switch to the certain state.

In practice, the combination of the cell state may be pre-configured in the combination information of the energy-saving cells, and a plurality of cell state combinations may be pre-configured, 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. When there are multiple cell state combinations, optionally, the energy-saving cell combination information may include at least one cell state combination and respectively used to identify at least one cell state. And combining the at least one combined index, and the status check message may include a first combination index for identifying the first cell state combination. Before the first base station selects the second cell according to the pre-configured energy-saving cell combination information, the method may further 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 three cell state combinations are included, so one combined index (0, 1, and 2 in Table 1) is configured in advance for each cell state combination. It is assumed that the first cell is the cell 2 in Table 1. When the load of the cell 2 is relatively low and the state of the cell 2 is desired to enter the energy-saving state, the control base station of the cell 2 (hereinafter referred to as the base station 2) can initiate the energy-saving state check process before the process is initiated. The base station 2 needs to select an appropriate cell state combination from the table 1, and finds that only the cell state combination corresponding to the index 2 can make the cell 2 enter the closed state, so the cell state combination corresponding to the combination index 2 is selected as the first cell state combination. .

Then, the cell 2 initiates the foregoing energy-saving state checking process, and the base station 2 sends a status check message to the control base station of the cell 3 (hereinafter referred to as the base station 3, which may be the same base station as the base station 2), and the status check message is used to query whether the cell 3 can Switch to the target state of cell 3 under combination index 2, that is, the compensation state. Specifically, the status check message may carry the combined index 2, and the station 3 selects the target status of the cell 3 under the combined index 2 according to the combined index 2. Obviously, if the above-mentioned energy-saving cell combination information includes only one cell state combination, the state 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 originating cell of the energy saving state checking process.

For example, including "Cell 1" in the status check message, indicating that the power saving status check process is small Zone 1 is initiated (of course, cell 1 is treated as a logical execution subject, in which the initiator of the energy saving state checking process is still the control base station of cell 1).

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

Specifically, the third cell may be any one of the group of cells, but the third cell must be able to know that the other cells can switch to the target state under the first cell state combination. However, the embodiment of the present invention knows whether the third cell can switch to the first hypothesis that the first cell is the cell 1, and the first cell state is combined into the cell state combination corresponding to the combination index 2. The energy saving state checking process may be performed by means of sequential inquiry, that is, the cell 1 queries whether the cell 2 can be switched to the off state, and when the cell 2 determines that the cell 2 can be switched to the off state, the cell 2 asks whether the cell 3 can switch to the compensation state, so Until the cell 5 determines that it can switch to the compensation state, the cell 5 finds that the next query target returns to the initiating cell (cell 1), and at this time, the cell 5 is the third cell, and the cell 5 (according to the above-mentioned root identifier) to the cell 1 Sending the above first status check success message. Of course, the above query process may also adopt a cell that does not query the target state of the first cell state combination to be in a normal state. When a cell finds that the target state of the next cell is a normal state, the cell is directly skipped and the inquiry is continued.

As another example, the cell 1 in Table 1 is ready to initiate a cell state combination with a combined index of 2, and the cell 1 selects one cell in the cell 4 and the cell 5 (a cell in a target state abnormal state) to make an inquiry, for example, the cell 5 is selected. After determining that the cell 5 can be switched to the compensation state, the cell 5 is selected from the remaining cells in the abnormal state of the target state, and only the cell 4 is left, so the state check message is sent to the cell 4, and the cell 5 is carried in the state check message. Determining the identification information that can be switched to the target state, after receiving the status check message, the cell 4 determines that the cell 4 can be switched to the compensation state, and after detecting that the remaining cells are all checked by the foregoing identification information, the cell 1 is The root identifier) sends the first state check success message described above.

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

Specifically, when all cells in a group of cells can be switched to a target state, A cell initiates a status update message, for example, in the above-mentioned inquiry-by-inquiry manner, when the last cell determines that it can switch to the target state, the cell initiates a status update in the reverse order of the inquiry one by one, and sequentially updates each The state of the cell is up to the first cell described above.

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

The foregoing fourth cell may be any cell other than the first cell in the foregoing group of cells, and specifically, if the first cell simultaneously sends a status check message to the remaining cells of the group of cells except the first cell, when When the cell in the remaining cells cannot be switched to the target state, the first state check failure message is sent to the first cell; or, if the state check message is sent in an inquiry-by-inquiry manner, when a cell cannot be switched to In the target state, the first state check failure message is sent to the first cell by using the root identifier in the state check message. The first base station can end the energy saving state check process as long as it receives a message that the status check failed. The embodiment of the present invention does not limit the specific manner of the process of checking the energy-saving state. 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 a remaining cell of the group of cells except the first cell, and the method of FIG. 2 may further include: the first base station separately receiving control of each of the remaining cells. The second state check success message sent by the base station is used to indicate that each cell can switch to the target state of each cell in the first cell state combination.

Specifically, the first base station sends a status check message to the control base station corresponding to all the remaining d areas, and when each of the remaining cells determines that the target state can be switched, the first base station directly returns a second status check success message to the first base station. , no root identification is required.

Optionally, as another embodiment, when the fifth cell in the remaining cell cannot be switched to the target state of the fifth cell in the first cell state combination, the method of FIG. 2 may further include: receiving, by the first base station, the fifth cell The second status check failure message sent by the control base station of the cell; the first base station ends the energy saving status 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 status check failure without the root identifier.

Optionally, as another embodiment, the method of FIG. 2 further includes: receiving, by the first base station, a second state check failure message sent by the control base station of the fifth cell; The fifth cell is a cell other than the first cell in the group of cells.

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

Specifically, the first base station sends a status update message to all remaining cells in the group of cells, where the message may include a first combined index and/or an update time. The update time is used to instruct the control base station of the other cell to switch the state of the other cell to the time of the target state of the other cell in the first cell state combination. When the remaining cell receives the status update message, the target status may be determined according to the first combined index (the index is not needed when only one cell status combination is available), and the time to switch to the target status may also be determined according to the update time.

With reference to FIG. 1 and FIG. 2, a method for cell energy saving compensation according to an embodiment of the present invention is described in detail from the perspective of a first cell (originating cell), and will be described below in connection with FIG. 3 from a second cell (receiving cell). The method for cell energy saving compensation according to an embodiment of the present invention is described.

It should be understood that the interaction and related characteristics, functions, and the like of the first cell and the second cell described on the second cell side correspond to the description on the first cell side, and the duplicate description is omitted as appropriate.

3 is a schematic flow chart of a method for cell energy saving compensation according to another embodiment of the present invention. The method of Figure 3 can be performed by a control base station of a second cell.

In the energy saving state check process, the second base station receives the first state check message sent by the first base station, the second base station is the control base station of the second cell, and the first base station is the control base station of the first cell, and the first state check is performed. The message is used to query whether the second base station can switch the second cell to the first target state, where the first target state is a target state of the second cell in the first cell state combination indicated by the energy-saving cell combination information, where the energy-saving cell combination The information is used to indicate at least one cell state combination of a group of cells including the first cell and the second cell, and each cell state combination in the at least one cell state combination includes each cell in a group of cells in each cell The target state under the combination of states, the target state is the normal state, the closed state, or the compensated state.

It should be understood that when the energy-saving cell combination information includes multiple cell state combinations, the combination of the first state check message may be carried in the foregoing first state check message to identify the first cell state combination. This identification is not needed when the energy-saving cell combination information includes only one cell state combination.

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

In the embodiment of the present invention, a set of cells is pre-configured with energy-saving cell combination information, where the energy-saving cell combination information includes at least one cell state combination, and the second cell may be configured according to at least one state when receiving the state check message of the energy-saving state check process. A cell state combination determines its target state, thereby providing an effective query mode suitable for various cell energy-saving compensation scenarios, and reducing the blindness of the existing query mode.

The first combination index, the determining, by the second base station, the first target state according to the first state check message may include: the second base station, according to the first combination index, selecting, from the energy-saving cell combination information, a cell state combination corresponding to the first combination index as the first a cell state combination; the second base station uses the target state of the second cell in the first cell state combination as the first target state.

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

Optionally, as another embodiment, the method of FIG. 3 may further include: when the second cell is capable of switching to the first target state, the second base station determines whether an unchecked cell remains in the group of cells; When the cell is not checked, the second base station selects the third cell from the unchecked cell; the second base station sends a second state check message to the control base station of the third cell, where the second state check message is used to query whether the third cell can switch to The target state of the third cell in the first cell state combination.

In the first mode, the energy-saving cell combination information includes the sequence information for indicating the sequence of the group of cells, and the energy-saving state check process sequentially checks, according to the indication of the arrangement information, whether a group of cells can be switched to the first cell state combination. The target state, the second base station determining whether the unchecked cell remains in the group of cells may include: the second base station determining, according to the arrangement information and the root identifier, whether the next first to-be-checked cell is the originating cell, where the first to-be-checked cell In order of priority, The second cell to the remaining cell between the initiating cells, or the first to-be-checked cell is the cell in the remaining cell, the target state in the first cell state combination is not in the normal state; the second base station selects the first in the unchecked cell The third cell includes: when the next first to-be-checked cell is not the initiating cell, the second base station selects the next first to-be-checked cell as the third cell.

In the energy saving state check, the initiating cell (assumed to be the cell 3) is sequentially checked to the right according to the position of each cell in Table 1. The cell 4 and the cell 5 are inspected in turn, and after the cell 5 is checked, the cell 1 is checked, then the cell 2 is checked, and finally the cell 3 is returned. In the foregoing process, the determining manner of the unchecked cell is to determine whether the next cell to be checked is the originating cell according to the root identifier. After the cell 4 checks, it is determined that the cell 5 is not the originating cell according to the root identifier, and then the cell 5 is continuously checked.

In the second mode, the first status check message further includes a checked cell identifier for indicating the checked cell in the group of cells, and the second base station determining whether the unchecked cell remains in the group of cells may include: the second base station according to the root The identifier and the checked identifier determine whether there is a second to-be-checked cell in the group of cells except the initiating cell, where the second to-be-checked cell is a remaining cell of the group of cells except the checked cell, or the second cell to be inspected is The cell in the remaining cell that is in the first cell state combination is not in the normal state; the second cell in the unchecked cell, the third cell may include: when there is still a second cell to be inspected in the group of cells The second base station selects a third cell from the second to-be-checked cell.

Referring to Table 1, for example, it is still assumed that cell 3 is an initiating cell, and cell 3 selects an unchecked cell from cells 1, 2, 4, and 5, for example, cell 5 is selected, and when cell 5 can be switched to a target state, One of the cells 1, 2, 4 selects a cell (such as cell 2) to send a status check message, and carries a cell 5 OK in the message to indicate that the cell 5 is checked, and the cell 4 receives the status check message and determines that it can switch to In the target state, it is determined that the cells 1 and 2 are unchecked cells according to the "OK" flag, and one of the cells 1 or 2 is selected to send a status check message, and carries the identifier of the cell 40K.

Optionally, as another embodiment, the method of FIG. 3 may further include: when there is no unchecked cell, the second base station sends a first state check success message to the control base station of the initiating cell according to the root identifier, where the first state check succeeds. The message is used to indicate that each cell in the group of cells except the initiating cell can switch to the target state of each cell under the first cell state combination.

409a, the cell 5 sends a status check failure message to the cell 1.

Before transmitting the message, the cell 5 uses the root identifier to determine that the cell 1 is the root cell.

409b, the cell 5 sends a status check success message to the cell 1.

The status, which provides an effective inquiry process, reduces the blindness of the inquiry method in the energy-saving compensation scenario.

FIG. 5 is a flowchart of a method for cell energy saving compensation according to an embodiment of the present invention. The method of FIG. 5 differs from the method of FIG. 4 in that, when the cell 5 determines that it is possible to switch to the target state, the state update process is directly started, and the order of the state update is sequentially performed in the reverse order of the transmission state check message.

The cell 5 determines that the previous cell of the cell 5 is the cell 4 based on the combined index.

510-512, similar to step 509, is that the current cell sends a status update message to a cell.

The combined update message may carry a combined index so that each cell determines the target state to which it is ready to switch. The status update message may also carry an activation time so that each cell switches to a specified target state at its respective activation time.

6 is a flow chart of a method for cell energy saving compensation according to an embodiment of the present invention. The method of FIG. 6 is different from the method of FIG. 4 in that each cell does not search for a cell to be inspected according to the sequence of cell locations in Table 1 (may also follow the sequence in the method of FIG. 4), but according to the detected in the state detection message. The cell identifier selects one of the undetected cells to send a status check message.

601. The cell 1 sends a status check message to the cell 3.

The message carries "root identifier = cell 1" and "combined index = 1". The cell 1 is the originating cell of the energy-saving state checking process, and the cell 1 selects one cell from all the undetected cells to send a status check message, and the message and the subsequent status check message may carry the identifier of the cell 1: OK. It also does not carry the identifier of "Cell 1: OK" (the default originating cell can switch to the target) Status).

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

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

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

Before transmitting the message, the cell 3 determines that the cell 1 is the originating cell according to the root identifier.

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

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

604~609a is similar to the previous process, and will not be described here.

609b, the cell 5 determines that there is no unchecked cell, and sends a status check message to the root cell (may also be a status check success message). The message carries all the identifiers of the cells that can be switched to the target state.

610, Community 1 makes a decision.

The cell 1 determines according to the received various messages. After the cell 1 receives the status check failure message sent by any of the cells 2 to 5, the energy saving state check process can be ended. When the cell 1 receives the status check message sent by a cell, and the status check message carries the identifier of the cell 1, 2, 3, 4, 5: OK, steps 611-614 are performed.

611-614: A status update message is sent to the cell 2 to the cell 5, which is similar to the steps 411 to 414, and details are not described herein again.

It should be understood that the state update manner of the embodiment of the present invention can also be performed in the manner of FIG. It should also be understood that in the combined index 1, the target state of all cells is an abnormal state (off state or compensated state), so each cell receives a status check message. However, under other combined indexes, such as combination index 2, cell 2 and cell 3 are in a normal state, it is possible to switch to the target state by default without receiving a status check message, so that only the unchecked process is required during the above check process. The cell to be inspected may be selected in the cell whose target state is in an abnormal state. After the cell in the abnormal state is detected, the state check success message may be sent to the cell 1.

Further, in the methods of FIG. 4 to FIG. 6 , when the cell 2 to cell 5 status check fails, the status check failure message may not be sent to the cell 1 to continue the next check, when all the cells After the check is completed, the last cell returns the check result of all the cells to the initiating cell, and the cell initiates a decision on the result and then makes a decision. For example, if the result shows that there is a cell that fails to switch to the target state, the energy saving state check is ended. Process; or if both cell 2 to cell 5 can switch to the target state, a status update process is performed.

7 is a flow chart of a method for cell energy saving compensation according to an embodiment of the present invention. The difference between the method of FIG. 7 and the method of FIG. 4-6 is that the energy-saving state checking process does not use the manner of sequential inquiry, but uniformly sends a status check message from cell 1 to cell 2 to cell 5 (can be separately sent, simultaneously sent, Or any transmission mode, which is not specifically limited by the present invention), the cell 2 to the cell 5 directly reply to the cell 1 after determining whether it is possible to switch to the target state.

701. The cell 1 sends a status check message to the cell 2.

The message carries "combined index =1".

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

The cell 2 determines that its target state is off based on the combined index =1, and determines whether it can switch to the off state according to its own load condition.

703. The cell 2 returns a status check result to the cell 1.

When cell 2 can be switched to the off state, the reply is successful; no, the reply fails.

Steps 704-712 are similar to the above steps. For convenience of description, details are not described herein again. It should be noted that, in the embodiment of the present invention, the order of interaction between the foregoing cell 1 and the remaining cells is not limited. It should also be noted that when there is a cell in a normal state in the cell 2 to the cell 5, the status check message may not be sent to the cell. For example, when the combined index selected by the cell 1 is 2, the status check message may be transmitted only to the cell 4 and the cell 5.

713, the community 1 to make a decision.

The cell 1 determines according to the received various messages. When receiving the failure message sent by a cell in the cell 2 to the cell 5, it can determine that the energy saving state check process fails; when the cell 2 to the cell 5 are successfully checked When performing steps 714-717.

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