The method and the device mainly add a cell splitting and convergence control function in a control plane of the access network device, and are used for dividing an area covered by a cell according to the load condition of the cell. Each cell comprises at least one radio frequency device, and the radio frequency device is used for transmitting signals of a specific frequency to enable users of the cell to carry out wireless communication.
It should be noted that the cell division of the present application is applicable to a wireless communication network; however, in a wired communication network, when wired resources are difficult to acquire, the network can be opened through wireless access, so that coverage of regional signals is realized.
In this embodiment of the present application, after obtaining a first load amount of a first cell, an access network device may determine, according to the first load amount, a current load condition of the first cell, and when the access network device determines that the first load amount is smaller than a first preset threshold, the access network device may expand a target area covered by the first cell according to the first load amount; when the access network device determines that the first load amount is greater than the second preset threshold, the access network device may reduce the target area covered by the first cell according to the first load amount. The cell division scheme of the present application is described below by embodiments, respectively.
First, when the access network device determines that the first load amount is smaller than a first preset threshold, the access network device may expand a target area covered by the first cell according to the first load amount. Referring to fig. 2A, the detailed description is provided below, and an embodiment of the method for dividing cells according to the present application includes:
201. the access network equipment acquires a first load capacity of the first cell.
The access network device may send a request message for querying a first load amount of a first cell to a radio frequency device of the first cell, and then the radio frequency device of the first cell may send the first load amount of the first cell to the access network device; as shown in fig. 2B, for example, the first cell includes a first area, and the first area includes a radio frequency device, so that the first load amount may be transmitted through the radio frequency device.
It should be noted that the first cell may also include more areas, and each of the more areas may include one radio frequency device. In practical applications, the first load amount may be sent by a radio frequency device in a certain area of the first cell.
202. The access network device determines that the first load amount is smaller than a first preset threshold.
The access network device may determine whether the first load amount is smaller than the first preset threshold, and then, when the first load amount is smaller than the first preset threshold, the access network device may determine that the area covered by the first cell is to be expanded.
203. And the access network equipment acquires a second load capacity of the second cell.
If the access network equipment determines that the first load is smaller than a first preset threshold, it is known that the current load condition of the first cell is lighter; the access network device may obtain a second load amount of a second cell, where the second cell may be a cell within a preset distance range from the first cell, and preferably, the second cell may be a cell with a smaller load amount determined by the access network device.
It should be noted that the access network device may also determine the second load amount of a certain area or certain areas in the second cell, and when the second load amount plus the first load amount of the first cell is within the load amount range borne by the first cell, the certain area or the certain areas and the first area may be divided into areas covered by the first cell at this time, and the division may be specifically performed according to actual situations, which is not limited in this application. In this embodiment, only the second load capacity of the second cell plus the first load capacity of the first cell is taken as an example to be described in the range of the load capacity borne by the first cell.
204. And the access network equipment determines a target load according to the first load and the second load.
And the access network equipment adds the first load capacity and the second load capacity to obtain a target load capacity.
205. And if the target load capacity is within the preset load capacity range carried by the first cell, taking the areas covered by the first area and the second cell as the target areas covered by the first cell.
The access network device may determine whether the target load is within a preset load range carried by the first cell, and if so, the access network device may use a first area covered by the first cell and an area covered by the second cell as a target area covered by the first cell. As shown in fig. 2B, assuming that the first cell includes the first region and the second cell includes the second region, the combined first cell includes the first region and the second region.
Through the scheme of the embodiment, the merged first cell comprises the first area and the second area, and even if users in the first area and the second area frequently walk back and forth indoors, the users do not need to switch frequently because the first area and the second area belong to the same cell, so that the experience of the users in network communication is improved. Secondly, through the technical scheme of the application, when the first load capacity is smaller, the first area and the second area can be combined into the first cell, the capacity of the first cell is set within the range which can be borne by the first cell, and the utilization rate of resources can be improved to a certain extent.
206. And the access network equipment sends the first control instruction to the radio frequency equipment in the target area.
The access network device divides a corresponding target area for the first cell, where the target area includes areas covered by the first cell and the second cell, and then the access network device may send a first control instruction to the radio frequency device in the target area, so that the radio frequency device in the target area operates using the signal frequency of the first cell. As shown in fig. 2B, the access network device may only send the first control instruction to the second area, and does not need to send the first control instruction to the first area.
207. And the access network equipment receives a first notification completion message sent by the radio frequency equipment of the target area.
After receiving the first control instruction, the radio frequency device in the target area may perform operation and parameter setting under the signal frequency switched to the first cell, and after the switching is completed, the radio frequency device in the target area may send a first notification completion message to the access network device, where the first notification completion message is used to instruct the radio frequency device in the target area to complete the operation of switching the operating frequency.
In the embodiment of the application, access network equipment acquires a first load capacity of a first cell; then, the access network device may allocate a corresponding target area for the first cell according to the first load amount, where the target area is an area covered by the first cell; the access network equipment sends a first control instruction to the radio frequency equipment in the target area, wherein the first control instruction is used for instructing the radio frequency equipment in the target area to work by using the signal frequency of the first cell. According to the technical scheme of the application, in the process of dividing the access network device into the cells, the access network device divides the first cell into the corresponding target area according to the load of the first cell, and then sends a control instruction to the radio frequency device of the divided target area, so that the radio frequency device works by using the signal frequency of the first cell, and the division of the target area corresponding to the first cell is realized. Therefore, the scheme for cell division of the present application is to divide the coverage area corresponding to the cell according to the current communication situation and the actual demand of the cell, and improves the flexibility of cell division compared with the prior art.
In this embodiment of the application, when the access network device determines that the first load amount is greater than the second preset threshold, the access network device may reduce the target area covered by the first cell according to the first load amount. Referring to fig. 3A for a detailed description, an embodiment of the method for dividing cells according to the present application includes:
301. the access network equipment acquires a first load capacity of the first cell.
The access network device may send a request message for querying a first load amount of the first cell to the radio frequency device of the first cell, and then the radio frequency device of the first cell may send the first load amount of the first cell to the access network device; as shown in fig. 3B, the first cell includes a first area and a second area, and then the access network device may select to acquire a first load amount of the first cell from the radio frequency device in one of the areas, where the first load amount is a load amount of the first area and the second area.
It should be noted that the first cell may also include more areas, and each area includes one radio frequency device.
302. The access network equipment determines that the first load amount is larger than a second preset threshold value.
The access network device may determine whether the first load amount is greater than a second preset threshold, and when the first load amount is greater than the first preset threshold, the access network device may determine that the current load amount of the first cell is greater, and it is necessary to reduce the area covered by the first cell, so as to implement that the area covered by the first cell and the system capacity are suitable for the capacity range accommodated by the second cell, thereby enabling the network in the first cell to reach a better state, and improving user experience.
303. The access network equipment acquires a first received power measurement report of a first area and a second received power measurement report of a second area.
The access network device may send a message requesting for querying a received power of the first area from the radio frequency device in the first area and send a message requesting for querying a received power of the second area to the radio frequency device in the second area, and then the access network device may obtain a first received power measurement report sent by the radio frequency device in the first area and a second received power measurement report sent by the radio frequency device in the second area.
304. The access network equipment determines a first number of users of the first area according to the first received power measurement report, and determines a second number of users of the second area according to the second received power measurement report.
After the access network device obtains the first received power measurement report and the second received power measurement report, the access network device may determine the number of first users in the first area and the number of second users in the second area according to the size of the received power measurement value.
305. If the number of the first users is smaller than the number of the second users, the access network equipment excludes the second area from the area covered by the first cell to obtain a target area covered by the first cell.
And when the access network equipment determines that the number of the first users is smaller than the number of the second users, the access network equipment excludes the second area from the area covered by the first cell to obtain a target area covered by the first cell. As shown in fig. 3B, the second area included in the first cell is excluded, and the target area covered by the first cell is left with the first area. The area covered by the first cell is reduced, so that the load of the first cell is within the load range borne by the first cell, the network quality of the first cell is good, and the user can smoothly communicate.
306. The access network device establishes a second cell.
The access network device may establish a second cell that includes the second region. As shown in fig. 3B, the target area covered by the second cell is set as the second area.
307. And the access network equipment sends a second control instruction to the radio frequency equipment of the second cell.
After the access network device allocates the second area to the second cell, the radio frequency device of the second cell may send a second control instruction, so that the radio frequency device of the second cell operates using the signal frequency of the second cell, thereby implementing division of the first cell.
308. And the access network equipment receives a second notification completion message sent by the radio frequency equipment of the second cell.
Step 308 is similar to step 207, and will not be described herein again.
