The present embodiment further ensures the accuracy of generating the signal area relationship between the wireless access points from the adjacent parameter information.
In order to deepen understanding of the above embodiments of the present application, the present application further provides a scene embodiment in a specific application scenario for further explanation.
Fig. 6 is a schematic diagram of a wireless access point signal area relationship according to a scenario embodiment.
Taking 5G channels as an example, every 20M channel is taken as a channel, the 5G channels can be divided into two major groups, 36-48 (4 channels in total) are taken as a first group of channels, and 149-161 (4 channels in total) are taken as a second group of channels. The first group is a priority channel and the second group is a spare channel.
Taking a as an example, the wireless access points with signal area overlapping relation with a are C, D and E. After obtaining the signal area relation, the following steps are carried out to allocate the channel:
1. dividing A into 36 channels, and then C, D and E can not be 36 channels;
2. randomly selecting an area from C, D and E, and if C is assumed, allocating 40 channels for C;
3. since both a and C have selected a channel and E is the channel most adjacent to the signal region of the selected channel, a channel is assigned to E, which is assigned to 44 channels.
4. Since a, C, E have all selected channels but there is no region adjacent to all three regions, D is the channel most adjacent to the signal region of the selected channel, then channel 48 is selected for D;
5. as can be seen from the above, B is the channel most adjacent to the signal region of the already selected channel, and channel 36 is selected for B;
6. f and G are both adjacent to a channel region, one region is randomly selected, and if G is assumed, a channel 40 is distributed for G;
7. finally F is assigned a channel 44.
The resulting channel allocation table for all wireless access points is shown in fig. 7.
In addition, fig. 8 is a schematic diagram illustrating another wireless access point signal area relationship in a scenario embodiment.
A and E, after removing themselves, still adjoin three or more identical signal regions (B, C, D, F), then a and E are overlapping regions and either a or E can be upgraded to a second set of channels. According to the four-color theorem, it can be determined that when B, C, D, and F are allocated to non-interfering channels, two channels a and E must be the same. Since the 36-48 (4 total) signals and 149-161 (4 total) channels have been previously grouped into two groups, to make a and E not on the same channel, E needs to be boosted. After the foregoing channel allocation procedure for the remaining channels, a channel allocation table for all wireless access points can be obtained as shown in fig. 9 below.
