All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Fig. 1 is a flowchart of a method for improving the quality of a private network voice according to an embodiment of the present invention. The embodiment provides a method for improving the voice quality of a private network, wherein an execution main body is a centralized scheduler, and as shown in fig. 1, the method specifically comprises the following steps:
s101, a centralized scheduler acquires a cluster voice semi-static activated subframe list of each cell in a cluster.
In this embodiment, the centralized scheduler may send an acquisition request to each base station in the cluster or receive a cluster voice semi-static activated subframe list actively sent by each base station in the cluster, where each cluster voice semi-static activated subframe list records time-frequency resource occupation information used by the cell during semi-static scheduling, that is, scheduling of a cluster voice service in a semi-static activated subframe.
S102, the centralized scheduler obtains a video schedulable subframe list of each cell according to the cluster voice semi-static activated subframe list.
In this embodiment, the centralized scheduler may obtain the video schedulable subframe list of each cell according to the trunking voice semi-static activated subframe list of each cell, where the video schedulable subframe of each cell needs to stagger the trunking voice semi-static activated subframes of all neighboring cells, that is, when all neighboring cells perform trunking voice service scheduling, the cell does not perform video service scheduling, and when the cell performs video service scheduling, all neighboring cells do not perform trunking voice service scheduling, thereby avoiding that the video service scheduling generates co-frequency interference to the trunking voice services of the neighboring cells, which results in missing words of the trunking voice of the neighboring cells.
S103, the centralized scheduler sends the video schedulable subframe list to a base station of a corresponding cell, so that the base station performs video service scheduling in the cell according to the video schedulable subframe list.
In this embodiment, after the centralized scheduler acquires the video schedulable subframe list of each cell in the cluster, the centralized scheduler sends the video schedulable subframe list to the corresponding base station, and each base station schedules the video service in the cell according to its respective video schedulable subframe list, that is, the base station performs the video service in the cell, such as the initial transmission and/or retransmission of the downlink video service, only in each video schedulable subframe in the video schedulable subframe list, and prohibits the video service in the non-video schedulable subframe, so that all cells in the cluster can not be subjected to the same frequency interference generated by the neighboring cell video service scheduling when performing the clustered voice service individually, thereby improving the quality of the clustered voice service and improving the system performance.
In the method for improving the voice quality of the private network provided in this embodiment, a concentrated scheduler is used to obtain a cluster voice semi-static activated subframe list of each cell in a cluster, a video schedulable subframe list of each cell is obtained according to the cluster voice semi-static activated subframe list, and then the video schedulable subframe list is sent to a base station of a corresponding cell, so that the base station performs video service scheduling in the cell according to the video schedulable subframe list. The centralized scheduler is used for carrying out interference coordination on all base stations in the cluster, and the base stations only carry out video service in the local cell in each video schedulable subframe in the video schedulable subframe list, so that any cell in the cluster can not be subjected to same frequency interference generated by adjacent cell video service scheduling when carrying out cluster voice service, cluster voice word loss is avoided, cluster voice service quality is improved, and system performance is improved.
On the basis of the foregoing embodiment, as shown in fig. 2, the acquiring, by the centralized scheduler in S102, a video schedulable subframe list of each cell according to the clustered voice semi-static activated subframe list may specifically include:
s1021, the centralized scheduler acquires a neighbor cell cluster voice semi-static activated subframe list of any cell according to the cluster voice semi-static activated subframe list of each cell;
s1022, the centralized scheduler obtains a video schedulable subframe list of the cell according to the neighboring cell cluster voice semi-static activated subframe list of the cell.
In this embodiment, the centralized scheduler first determines neighboring cells (assuming that B and C are provided) of any cell a in a cluster, then finds out a clustered voice semi-static activated subframe list of the neighboring cells B and C from the obtained clustered voice semi-static activated subframe list of each cell, and then obtains a neighboring cell clustered voice semi-static activated subframe list of the cell a according to the clustered voice semi-static activated subframe lists of the neighboring cells B and C, that is, the clustered voice semi-static activated subframe lists of the cells B and C are fused, for example, the cell B performs clustered voice service scheduling in a first subframe, the cell C performs clustered voice service scheduling in a third subframe, and then the first subframe and the third subframe in the neighboring cell clustered voice semi-static activated subframe list of the cell a are occupied by the clustered voice service scheduling of the neighboring cells. The same process is performed for all cells in the cluster according to the above operation. As an example, the correspondence between the neighbor cluster voice semi-static activated subframe list and the video schedulable subframe list is shown in fig. 3. After the centralized scheduler obtains the neighboring cell cluster voice semi-static activated subframe list of the cell a, the video schedulable subframe list of the cell a can be obtained according to the neighboring cell cluster voice semi-static activated subframe list of the cell a.
Specifically, the acquiring, by the centralized scheduler, the video schedulable subframe list of the cell according to the neighboring cell cluster voice semi-static activated subframe list of the cell may specifically include:
the centralized scheduler acquires a voice scheduling interval of the neighboring cell cluster according to the voice semi-static activated subframe list of the neighboring cell cluster;
and inserting video schedulable subframes in the voice scheduling interval of the cluster of the adjacent area so as to form a video schedulable subframe list.
In this embodiment, the centralized scheduler obtains the neighboring cell trunking voice scheduling interval according to the neighboring cell trunking voice semi-statically activated subframe list, for example, in the above example, the first subframe and the third subframe in the neighboring cell trunking voice semi-statically activated subframe list of cell a are occupied by the neighboring cell trunking voice service scheduling, and the neighboring cell trunking voice scheduling interval can be obtained as the interval between the first subframe and the third subframe, so the second subframe is inserted into the interval between the first subframe and the third subframe to be used as the video schedulable subframe, all subframes are processed according to the above processing, so as to obtain the video schedulable subframe list, cell a performs the video service in this cell only in each video schedulable subframe in the video schedulable subframe list, i.e. the video service scheduling of cell a can be staggered with the trunking voice service scheduling of its neighboring cells B and C, the video service scheduling of the cell A can not generate the same frequency interference to the video service scheduling of the adjacent cell. Similarly, the cell B and the cell C also perform video service only in each video schedulable subframe in their respective video schedulable subframe lists, and will not generate co-channel interference to the trunking voice service of the cell a.
It should be noted that, the priority of the trunking voice service is higher than that of the video service, so if all the subframes in the neighboring trunking voice semi-static activated subframe list are occupied by trunking voice service scheduling, video service scheduling is not performed.
On the basis of the foregoing embodiment, the acquiring, by the centralized scheduler in S101, a cluster voice semi-static activated subframe list of each cell in a cluster may specifically include:
the centralized scheduler sends an acquisition request to the base station of each cell in the cluster in a preset period, and receives a cluster voice semi-static activated subframe list fed back by the base station of each cell according to the acquisition request; or alternatively
And the centralized scheduler receives a cluster voice semi-static activated subframe list sent by the base station of each cell in the cluster in a preset period.
In this embodiment, the centralized scheduler may send an acquisition request to the base station of each cell at a predetermined period, and the base station of each cell sends a trunking voice semi-static activated subframe list fed back to the centralized scheduler according to the acquisition request, or the base station of each cell actively sends the trunking voice semi-static activated subframe list to the centralized scheduler at the predetermined period, where the predetermined period may be set to 100ms, and the trunking voice semi-static activated subframe list sent by the base station of each cell may be a trunking voice semi-static activated subframe list within current 20 ms. That is, the cluster voice semi-static activated subframe list in the current 20ms is used for carrying out cluster voice service and video service scheduling in the preset period of 100ms, so that the system resource consumption caused by frequently updating the cluster voice semi-static activated subframe list is avoided.
In the method for improving the voice quality of the private network provided by this embodiment, interference coordination is performed on all base stations in a cluster through a centralized scheduler, and the base stations perform video services in the local cell only in each video schedulable subframe in a video schedulable subframe list, so that any cell in the cluster does not suffer from same frequency interference generated by scheduling of video services in neighboring cells when performing trunking voice services, cluster voice word loss is avoided, the cluster voice service quality is improved, and the system performance is improved.
Fig. 4 is a flowchart of a method for improving the quality of a private network voice according to an embodiment of the present invention. The embodiment provides a method for improving the voice quality of a private network, wherein an execution subject is a base station, and as shown in fig. 4, the method specifically includes the following steps:

S202, the base station receives a video schedulable subframe list sent by the centralized scheduler, wherein the video schedulable subframe list is obtained by the centralized scheduler according to the cluster voice semi-static activated subframe list of each cell.
In this embodiment, after all base stations in a cluster send a clustered voice semi-static activated subframe list of a local cell to a centralized scheduler, the centralized scheduler may obtain a video schedulable subframe list of each cell according to the clustered voice semi-static activated subframe list of each cell, where the video schedulable subframe of each cell needs to stagger the clustered voice semi-static activated subframes of all neighboring cells, that is, when all neighboring cells perform clustered voice service scheduling, the cell does not perform video service scheduling, and when the cell performs video service scheduling, all neighboring cells do not perform clustered voice service scheduling, thereby avoiding that the video service scheduling generates co-frequency interference on clustered voice services of neighboring cells, which results in cluster voice missing words of neighboring cells. And after the centralized scheduler acquires the video schedulable subframe list of each cell in the cluster, the centralized scheduler sends the video schedulable subframe list to the corresponding base station.
And S203, the base station carries out video service scheduling in the cell according to the video schedulable subframe list.
In this embodiment, the base station performs video service scheduling in the local cell according to the video schedulable subframe list, that is, the base station performs video services, such as initial transmission and/or retransmission of a downlink video service, in the local cell only in each video schedulable subframe in the video schedulable subframe list, and prohibits the video services in a non-video schedulable subframe, so that all cells in a cluster are not subjected to co-frequency interference generated by neighboring cell video service scheduling when performing trunking voice services, thereby improving trunking voice service quality and system performance.
In the method for improving the voice quality of the private network provided in this embodiment, a concentrated scheduler is used to obtain a cluster voice semi-static activated subframe list of each cell in a cluster, a video schedulable subframe list of each cell is obtained according to the cluster voice semi-static activated subframe list, and then the video schedulable subframe list is sent to a base station of a corresponding cell, so that the base station performs video service scheduling in the cell according to the video schedulable subframe list. The centralized scheduler is used for carrying out interference coordination on all base stations in the cluster, and the base stations only carry out video service in the local cell in each video schedulable subframe in the video schedulable subframe list, so that any cell in the cluster can not be subjected to same frequency interference generated by adjacent cell video service scheduling when carrying out cluster voice service, cluster voice word loss is avoided, cluster voice service quality is improved, and system performance is improved.
On the basis of the foregoing embodiment, the sending, by the base station to the centralized scheduler, the cluster voice semi-static activated subframe list of the cell by the base station in S201 may specifically include:
the base station sends a cluster voice semi-static activated subframe list of the cell to the centralized scheduler in a preset period; or alternatively
And after receiving an acquisition request sent by the centralized scheduler to the base station of each cell in the cluster in a preset period, the base station feeds back a cluster voice semi-static activated subframe list of the cell to the centralized scheduler.
