Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
One of the core ideas of the embodiment of the invention is that when a plurality of overlapped cells have few users and the PRB loads of several cells are high and the PRB loads of other cells are low, the cells with low loads are deactivated, so that the resources of the cells with low loads are saved.
The multiple cells with overlapping coverage may refer to multiple cells with the same coverage, for example, in a 5-layer networking, the multiple cells with overlapping coverage may refer to 5 cells with the same coverage and different frequency points; the several cells with overlapping coverage can be adjacent cells with the same coverage. For example, if the 5 overlapping coverage cells include A, B, C, D, E, B, C, D, E are all the same-coverage neighboring cells of a, A, C, D, E are all the same-coverage neighboring cells of B, A, B, D, E are all the same-coverage neighboring cells of C, A, B, C, E are all the same-coverage neighboring cells of D, and A, B, C, D are all the same-coverage neighboring cells of E.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for controlling resources of a cell according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, one cell can be selected from a plurality of overlapped cells to serve as the energy-saving cell, and then whether the energy-saving cell needs energy saving is judged by judging whether the energy-saving cell meets the energy-saving condition. When the energy-saving cell meets the energy-saving condition, it can be determined that the energy-saving cell needs energy saving, and at this time, it can be determined whether energy-saving processing needs to be performed on the energy-saving cell according to the resource condition of the same-coverage neighboring cell of the energy-saving cell. In the embodiment of the present invention, whether energy saving processing needs to be performed on the energy saving cell may be jointly determined according to the PRB load and the number of users of the same-coverage neighboring cells of the energy saving cell, and specifically, refer to steps 102 to 104.
Certainly, when the energy-saving cell does not satisfy the energy-saving condition, it may be determined that the cell does not need to save energy, and at this time, another cell may be selected again from the multiple overlapping coverage cells as the energy-saving cell, and then it is determined whether the energy-saving cell needs energy saving and whether energy-saving processing is performed on the energy-saving cell.
And step 102, judging whether the energy-saving cell has a same-coverage adjacent cell with a Physical Resource Block (PRB) load higher than a first load threshold.
In the embodiment of the present invention, when it is determined that the energy saving cell satisfies the energy saving condition, it may be determined that the energy saving cell needs to save energy, and at this time, it may be sequentially determined whether PRB loads of all same-coverage neighboring cells of the energy saving cell are higher than a first load threshold. If the PRB load of at least one co-coverage neighboring cell of the energy-saving cell is higher than the first load threshold, it may be determined that the energy-saving cell has a co-coverage neighboring cell with a PRB load higher than the first load threshold, and at this time, step 103 may be executed. If the same-coverage neighbor cell with the PRB load higher than the first load threshold does not exist in the same-coverage neighbor cells of the energy-saving cell, it can be determined that the same-coverage neighbor cell with the PRB load higher than the first load threshold does not exist in the energy-saving cell, and at this moment, the above process can be ended, that is, the energy-saving cell does not need to be subjected to energy-saving processing. The first load threshold may be determined according to a requirement, which is not limited in this embodiment of the present invention.
And 103, judging whether the number of the users of the same-coverage adjacent cells is lower than a user number threshold.
In the embodiment of the invention, if the energy-saving cell has a same-coverage neighboring cell with a PRB load higher than a first load threshold, whether the number of users of the same-coverage neighboring cell is lower than a user number threshold can be further judged; the user number threshold may be determined according to a requirement, which is not limited in the embodiment of the present invention. When the number of users of the same-coverage neighboring cell is lower than the user number threshold, energy-saving processing can be performed on the energy-saving cell, and when the number of users of the same-coverage neighboring cell is not lower than the user number threshold, the above process can be ended, that is, energy-saving processing is not required to be performed on the energy-saving cell.
And 104, deactivating the energy-saving cell.
In the embodiment of the invention, when the energy-saving cell has a same-coverage cell with PRB load higher than a first load threshold and the number of users of the same-coverage cell is lower than a user number threshold, the energy-saving cell can be subjected to energy-saving processing; the energy-saving cell can be deactivated to save resources of the energy-saving cell.
Of course, after the energy saving cell is energy-saved, one cell may be selected again from the several overlapped cells as the energy saving cell, and then step 101 to step 104 are performed to determine whether to perform energy saving processing on the selected energy saving cell again.
In summary, in the embodiment of the present invention, it may be determined whether an energy saving cell meets an energy saving condition, and if the energy saving cell meets the energy saving condition, it is determined whether a same-coverage neighboring cell with a physical resource block PRB load higher than a first load threshold exists in the energy saving cell; if the same-coverage adjacent cell with the PRB load higher than a first load threshold exists, judging whether the number of users of the same-coverage adjacent cell is lower than a user number threshold, and if the number of users of the same-coverage adjacent cell is lower than the user number threshold, deactivating the energy-saving cell; and then according to the PRB load and the number of users of the adjacent cells with the same coverage, judging whether to perform energy-saving processing on the energy-saving cell, so that the cells with low load are deactivated under the condition that the number of users in a plurality of cells with overlapped coverage is small, and the PRBs of a plurality of cells are high and the PRBs of other cells are low, thereby saving the resources of the cells with low load.
In the embodiment of the invention, after the energy-saving cell is deactivated, other users may enter the areas correspondingly covered by the overlapped coverage cells; if the energy-saving cell is still in the deactivated state, the service requirements of other users may not be well met. Therefore, the embodiment of the invention can recover the energy-saving cell at regular time and deactivate the energy-saving cell at regular time, thereby avoiding influencing the service requirement of a user on the premise of saving cell resources.
The energy saving processing performed on the energy saving cell at regular time will be described as an example.
Referring to fig. 2, a flowchart illustrating steps of an alternative embodiment of a method for controlling resources of a cell according to the present invention is shown.
In an implementation manner of the embodiment of the present invention, an energy-saving timer may be set for an energy-saving cell, where a timing duration of the energy-saving timer is an energy-saving period; the energy saving period may be a period for determining whether to save energy for an energy saving cell. Then, whether the energy-saving period of the energy-saving cell is reached can be judged by judging whether the energy-saving timer is overtime; when the energy-saving timer is over, it may be determined that the energy-saving period corresponding to the energy-saving cell is reached, and at this time, step 202 may be executed; when the energy saving timer does not time out, it may be continuously determined whether the energy saving timer times out, that is, step 201 is performed.
In the embodiment of the invention, if the energy-saving timer is overtime, which indicates that the energy-saving period of the energy-saving cell is reached, whether the energy-saving cell meets the energy-saving condition can be judged; the PRB load of the energy-saving cell may be determined, and then it is determined whether the PRB load of the energy-saving cell is smaller than a second load threshold. When the PRB load of the energy-saving cell is less than the second load threshold, it indicates that the energy-saving cell meets the energy-saving condition, and step 203 may be executed; when the PRB load of the energy-saving cell is not less than the second load threshold, the energy-saving cell does not meet the energy-saving condition, and the process can be ended; step 201 may be executed, and step 202 may be executed when the next energy saving period is reached.
The second load threshold is smaller than the first load threshold, the first load threshold may refer to an energy-saving PRB high load threshold, the second load threshold may refer to an energy-saving PRB low load threshold, and the second load threshold may also be set according to a requirement, which is not limited in this embodiment of the present invention.
In the embodiment of the present invention, if it is determined that the energy-saving cell needs energy saving, steps 203 to 204 may be executed to determine whether to perform energy-saving operation on the energy-saving cell.
And 203, judging whether the energy-saving cell has a same-coverage adjacent cell with a Physical Resource Block (PRB) load higher than a first load threshold.
And 204, judging whether the number of the users of the same-coverage adjacent cells is lower than a user number threshold.
And step 205, turning off the carrier wave of the energy-saving cell.
In the embodiment of the invention, when the energy-saving cell has a same-coverage cell with PRB load higher than a first load threshold and the number of users of the same-coverage cell is lower than a user number threshold, the energy-saving cell can be subjected to energy-saving processing; the carrier of the energy-saving cell can be turned off, and the energy-saving cell is deactivated.
In summary, in the embodiment of the present invention, it may be determined whether an energy saving cell meets an energy saving condition, and if the energy saving cell meets the energy saving condition, it is determined whether a same-coverage neighboring cell with a physical resource block PRB load higher than a first load threshold exists in the energy saving cell; if the same-coverage adjacent cell with the PRB load higher than a first load threshold exists, judging whether the number of users of the same-coverage adjacent cell is lower than a user number threshold, and if the number of users of the same-coverage adjacent cell is lower than the user number threshold, deactivating the energy-saving cell; and then according to the PRB load and the number of users of the adjacent cells with the same coverage, judging whether to perform energy-saving processing on the energy-saving cell, so that the cells with low load are deactivated under the condition that the number of users in a plurality of cells with overlapped coverage is small, and the PRBs of a plurality of cells are high and the PRBs of other cells are low, thereby saving the resources of the cells with low load.
Secondly, in the embodiment of the invention, before judging whether the energy-saving cell meets the energy-saving condition, whether the energy-saving period is reached can be judged, so that the energy-saving cell is periodically saved, and the energy-saving effect of the cell is improved.
The energy saving recovery of the energy saving cell will be described as an example in the following.
Referring to fig. 3, a flowchart illustrating steps of an embodiment of a power saving restoration method of the present invention is shown.
In the embodiment of the invention, in order to prevent the carrier of the energy-saving cell from being turned off for a long time and cannot well meet the service requirement of other users after entering the corresponding coverage area of the energy-saving cell, a recovery timer can be set, and the timing duration of the recovery timer is a recovery period; the recovery period may be a period used to determine whether to recover the energy saving cell from the deactivated state to the activated state. Then, whether the recovery period of the energy-saving cell is reached can be judged by judging whether the recovery timer is overtime or not; when the recovery timer times out, it may be determined that a recovery period corresponding to the energy saving cell arrives, and at this time, step 302 may be performed; when the recovery timer has not expired, it may be continuously determined whether the recovery timer has expired, i.e., step 301 is executed.
In the embodiment of the invention, when the recovery period of the energy-saving cell is reached, whether the energy-saving cell is activated or not can be judged, and the energy-saving cell is recovered to an activated state; whether the energy-saving cell is activated can be judged according to the PRB load and the number of users of the same-coverage adjacent cells of the energy-saving cell.
In the embodiment of the present invention, when it is determined that the recovery period arrives, it may be sequentially determined whether the PRB load of each of the same-coverage neighboring cells of the energy saving cell is higher than the first load threshold at this time. If the PRB load of at least one same-coverage neighboring cell of the energy-saving cell is higher than the first load threshold, it may be determined that the PRB load of the physical resource block of the same-coverage neighboring cell of the energy-saving cell is higher than the first load threshold, and at this time, step 303 may be executed. If the same-coverage neighbor cell with the PRB load higher than the first load threshold does not exist in the same-coverage neighbor cells of the energy-saving cell, determining that the same-coverage neighbor cell with the PRB load higher than the first load threshold does not exist in the energy-saving cell, and at this time, the energy-saving cell does not need to be recovered, and the deactivation state of the energy-saving cell is maintained; then, the above-described flow may be ended, or step 301 may be executed, and step 302 may be executed after the next recovery period is reached.
And step 303, judging whether the number of users of the same-coverage neighboring cell is higher than a user number threshold.
In the embodiment of the present invention, when the PRB load of the same-coverage neighboring cell of the energy-saving cell is higher than the first load threshold, it may be further determined whether the number of users of the same-coverage neighboring cell is higher than the user number threshold. When the number of users in the same-coverage neighboring cell is higher than the user number threshold, it may be determined that there are more users in the coverage area corresponding to the energy-saving cell and the same-coverage neighboring cell, and at this time, step 304 may be executed to recover the energy-saving cell. When the number of users in the same-coverage neighboring cell is not higher than the user number threshold, it may be determined that the number of users in the coverage area corresponding to the energy-saving cell and the same-coverage neighboring cell is small, and at this time, the energy-saving cell does not need to be recovered, the deactivation state of the energy-saving cell is maintained, and then the above procedure may be ended, or step 301 may be executed, and step 302 is executed when a next recovery period is reached.
In the embodiment of the invention, when the PRB load of the same-coverage adjacent cell of the energy-saving cell is higher than the first load threshold and the number of users of the same-coverage adjacent cell is higher than the user number threshold, the carrier of the energy-saving cell can be started, the energy-saving cell is activated, and the energy-saving cell is recovered.
In summary, in the embodiment of the present invention, when the recovery period of the energy saving cell is reached, it is determined whether a physical resource block PRB load of a same-coverage neighboring cell of the energy saving cell is higher than a first load threshold; if the Physical Resource Block (PRB) load of a same-coverage adjacent cell of the energy-saving cell is higher than a first load threshold, judging whether the number of users of the same-coverage adjacent cell is higher than a user number threshold; if the number of the users in the same-coverage adjacent cell is higher than the user number threshold, activating the energy-saving cell; and further, the carrier of the energy-saving cell is prevented from being turned off for a long time, and the service requirement of other users after entering the corresponding coverage area of the energy-saving cell cannot be met.
In another embodiment of the invention, the energy-saving cell is activated under the condition that the PRB load of the same-coverage adjacent cell is higher and the number of users is more, namely the same-coverage cell is a high-load cell, and the energy-saving cell is a low-load cell; therefore, after the energy-saving cell is activated, the same coverage cell can balance users to the energy-saving cell. In the process of balancing users from the same-coverage adjacent cell to the energy-saving cell, judging whether the number of the users of the same-coverage adjacent cell is lower than or equal to a user number threshold; and if the number of the users in the energy-saving cell is lower than or equal to the user number threshold, stopping balancing the users to the energy-saving cell. And further, when the number of users in the same coverage neighbor cell reaches or is lower than the user number threshold, even if the PRB load does not reach the balance, the users are stopped to be balanced to the energy-saving cell.
