and step S30, selecting a discrete frequency point with the highest priority to be allocated to the first discrete frequency point cluster according to the priority sequence of the discrete frequency points to be allocated in the first discrete frequency point cluster.
Specifically, first, it is determined whether a discrete frequency point cluster needs a discrete frequency point, where the discrete frequency point cluster may refer to a cell. It is often necessary to allocate a plurality of discrete frequency points in a cell, where the discrete frequency points form a cluster of discrete frequency points.
Then, if the discrete frequency point cluster is judged to be required by the discrete frequency point cluster, determining the priority order of the discrete frequency points to be allocated in the discrete frequency point cluster, wherein the discrete frequency points to be allocated can be all available discrete frequency points including authorized, unauthorized, public and the like, and the discrete frequency points to be allocated are not included, and the priority order is obtained by arranging the discrete frequency points to be allocated according to a preset rule from high priority to low priority. If the discrete frequency point cluster is judged to be not needed, judging whether another discrete frequency point cluster needs discrete frequency points or not again.
And then selecting a discrete frequency point with the highest priority to be allocated to the discrete frequency point cluster according to the priority order of the discrete frequency points to be allocated in the discrete frequency point cluster, wherein the allocation process is real-time and dynamic allocation.
Further, the determining whether the discrete frequency point cluster needs discrete frequency points includes: judging whether a first discrete frequency point cluster needs discrete frequency points or not, judging whether a second discrete frequency point cluster needs discrete frequency points or not, acquiring a first discrete frequency point demand of the first discrete frequency point cluster and a second discrete frequency point demand of the second discrete frequency point cluster, and comparing the first discrete frequency point demand with the second discrete frequency point demand;

determining the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster;
and selecting a discrete frequency point with the highest priority to be allocated to the first discrete frequency point cluster according to the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster.
Specifically, in a certain area range, a plurality of discrete frequency point clusters are arranged, two are taken as an example, whether a first discrete frequency point cluster needs discrete frequency points or not is judged, whether a second discrete frequency point cluster needs discrete frequency points or not is judged, a first discrete frequency point demand c1 of the first discrete frequency point cluster and a second discrete frequency point demand c2 of the second discrete frequency point cluster are obtained, and the first discrete frequency point demand c1 and the second discrete frequency point demand c2 are compared;
if the first discrete frequency point cluster is judged to be required to be obtained, the second discrete frequency point cluster is required to be obtained, and c1 is larger than c2, determining the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster;
and selecting a discrete frequency point with the highest priority to be allocated to the first discrete frequency point cluster according to the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster.
Further, the determining the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster specifically includes: and determining the priority order of the discrete frequency points to be allocated in the first discrete frequency point cluster according to whether each discrete frequency point to be allocated is an authorized discrete frequency point, whether the same-frequency interference can be avoided only by being allocated to the first discrete frequency point cluster, whether the discrete frequency points are public discrete frequency points and whether the discrete frequency points to be allocated are forbidden discrete frequency points.
Specifically, the 230MHz band includes 223.025-235.000 total 12MHz bandwidth. Currently, 25kHz is used as one discrete frequency point for distribution, 480 discrete frequency points are used, wherein approximately 100 discrete frequency points are distributed to energy sources, armies, weather, earthquakes, water conservancy, land mines, light industry and construction by the State radio administration, 8 ministry of the industry are used, the rest 380 discrete frequency points are distributed by the State radio administration according to industry requirements and cluster intervals, and some common discrete frequency points are available. The discrete frequency points authorized for the energy department are unauthorized discrete frequency points relative to the meteorological part, sometimes, under some conditions, the unauthorized discrete frequency points are allowed to be used, some discrete frequency points are different in the same-frequency interference condition received by different discrete frequency point clusters, some discrete frequency points can only be used in one discrete frequency point cluster, the same-frequency interference can exist in other discrete frequency point clusters, and then the discrete frequency points are unique relative to the discrete frequency point clusters.
Therefore, since the discrete frequency point quality of one discrete frequency point in different discrete frequency point clusters is different, depending factors of the situation are various, for example, whether the discrete frequency point to be allocated is an authorized discrete frequency point, whether the discrete frequency point to be allocated can only be allocated to the discrete frequency point cluster, the same-frequency interference can be avoided, whether the discrete frequency point to be allocated is a public discrete frequency point, whether the discrete frequency point to be allocated is a forbidden discrete frequency point, and the like, according to the factors, the discrete frequency point to be allocated can be divided into the only authorized discrete frequency point; the authorized discrete frequency points are not unique; unauthorized public discrete frequency point and uniqueness, disable discrete frequency point, 7 grades, and priority level is reduced in sequence.
Further, the determining whether the first discrete frequency point cluster needs discrete frequency points specifically includes:
determining a first target discrete frequency point demand of a first discrete frequency point cluster according to the number of terminals and traffic in a cell coverage area corresponding to the first discrete frequency point cluster, judging whether the first discrete frequency point cluster needs discrete frequency points according to the first target discrete frequency point demand and the first allocated discrete frequency point quantity, if so, judging that the first target discrete frequency point demand is larger than the first allocated discrete frequency point quantity, the first discrete frequency point cluster needs discrete frequency points, and if so, judging that the first target discrete frequency point demand is smaller than or equal to the first allocated discrete frequency point quantity, the first discrete frequency point cluster does not need discrete frequency points;
the judging whether the second discrete frequency point cluster needs discrete frequency points specifically comprises:
determining a second target discrete frequency point demand of a second discrete frequency point cluster according to the number of terminals and the traffic volume in a cell coverage area corresponding to the second discrete frequency point cluster, judging whether the second discrete frequency point cluster needs discrete frequency points according to the second target discrete frequency point demand and the second allocated discrete frequency point quantity, if the second target discrete frequency point demand is judged to be larger than the second allocated discrete frequency point quantity, the second discrete frequency point cluster needs discrete frequency points, and if the second target discrete frequency point demand is judged to be smaller than or equal to the second allocated discrete frequency point quantity, the second discrete frequency point cluster does not need discrete frequency points.
Specifically, since there are generally multiple terminals in the coverage area of the cell corresponding to the discrete frequency point cluster, and the services made by different terminals are different, for example, some terminals are performing voice services and some terminals are performing video services, the requirements of different cells on the discrete frequency points are also different.
Taking a first discrete frequency point cluster as an example, firstly, determining a first target discrete frequency point demand a1 of the first discrete frequency point cluster according to the number of terminals and the traffic volume in a cell coverage area corresponding to the first discrete frequency point cluster, wherein an acquisition method can be determined according to information reported by the terminals, the first allocated discrete frequency point quantity which is already allocated to the first discrete frequency point cluster is b1, if a1 is judged to be greater than b1, the first discrete frequency point cluster needs discrete frequency points, and if a1 is judged to be less than b1, the first discrete frequency point cluster does not need discrete frequency points.
Further, the obtaining the first discrete frequency point demand of the first discrete frequency point cluster specifically includes:
a1-b1＝c1；
wherein a1 is a first target discrete frequency point demand of a first discrete frequency point cluster determined according to the number of terminals and the traffic volume in a cell coverage area corresponding to the first discrete frequency point cluster, b1 is a first allocated discrete frequency point quantity of the first discrete frequency point cluster, and c1 is a first discrete frequency point demand of the first discrete frequency point cluster;
the second discrete frequency point demand for obtaining the second discrete frequency point cluster specifically comprises the following steps:
a2-b2＝c2；
wherein a2 is a second target discrete frequency point demand of a second discrete frequency point cluster determined according to the number of terminals and the traffic volume in a cell coverage area corresponding to the second discrete frequency point cluster, b2 is a second allocated discrete frequency point quantity of the second discrete frequency point cluster, and c2 is a second discrete frequency point demand of the second discrete frequency point cluster.
Specifically, for example, the target discrete frequency point demand of the first discrete frequency point cluster is 10, the allocated discrete frequency point is 4, the discrete frequency point demand of the first discrete frequency point cluster is 6, the target discrete frequency point demand of the second discrete frequency point cluster is 9, the allocated discrete frequency point is 1, the discrete frequency point demand of the second discrete frequency point cluster is 8, and because the discrete frequency point demand of the second discrete frequency point cluster is greater than the discrete frequency point demand of the first discrete frequency point cluster, when the discrete frequency points are dynamically allocated, the discrete frequency points are preferentially allocated to the second discrete frequency point cluster.
Further, the priority sequence at least comprises a first priority discrete frequency point to be allocated and a second priority discrete frequency point to be allocated, and the priority of the first priority discrete frequency point to be allocated is higher than that of the second priority discrete frequency point to be allocated;
correspondingly, according to the priority order of the discrete frequency points to be allocated in the discrete frequency point cluster, selecting a discrete frequency point with the highest priority to be allocated to the discrete frequency point cluster specifically comprises the following steps:
judging whether the number of the discrete frequency points to be allocated in the first priority is zero or not;
if the number of the discrete frequency points to be allocated of the first priority is zero, selecting a discrete frequency point to be allocated of a second priority to be allocated to the discrete frequency point cluster;
and if the number of the discrete frequency points to be allocated with the first priority is not zero, randomly selecting one discrete frequency point to be allocated with the first priority to be allocated to the discrete frequency point cluster.
Specifically, since the discrete frequency point allocation process is real-time and dynamic, one discrete frequency point is selected to be allocated to one discrete frequency point cluster in each allocation process. When the discrete frequency points to be allocated are divided into a plurality of priorities, the same priority can contain a plurality of discrete frequency points, in this embodiment, taking two priorities of only authorized discrete frequency points and not only authorized discrete frequency points as examples, if the number of the unique discrete frequency points of the authorized discrete frequency points is not zero, and if a plurality of discrete frequency points exist, the discrete frequency point clusters allocated by only one unique discrete frequency point of the authorized discrete frequency points are selected randomly preferentially, and if the number of the unique discrete frequency points of the authorized discrete frequency points is zero, the non-unique discrete frequency points of the authorized discrete frequency points are taken into consideration for allocation.
Fig. 3 is a flowchart of a discrete frequency point planning method according to an embodiment of the present invention, and as shown in fig. 3, the discrete frequency point planning method may be summarized as the following flow:
1. starting;
2. acquiring available discrete frequency points F1, F2 and F3 … of different discrete frequency point clusters;

9. and (5) ending.
According to the discrete frequency point planning method provided by the embodiment of the invention, the target discrete frequency point demand of the discrete frequency point cluster is determined by acquiring the number of terminals and the traffic volume in the coverage area of the cell corresponding to the discrete frequency point cluster, the discrete frequency point demand of the discrete frequency point cluster is determined by the allocated discrete frequency point quantity, one discrete frequency point with the highest priority is selected to be allocated to the discrete frequency point cluster according to the priority order of the discrete frequency points to be allocated in the discrete frequency point cluster according to the discrete frequency point demand of the discrete frequency point cluster, the discrete frequency point demand of different discrete frequency point clusters is compared, the discrete frequency point cluster with larger discrete frequency point demand is preferentially allocated, and the allocation process is real-time and dynamic, so that the utilization rate of the discrete frequency point resource is improved.
