Please refer to Figure 2. Figure 2 is a schematic flow chart of a cell reselection method disclosed in Embodiment 1 of the present invention. As shown in Figure 2, the cell reselection method may include:

201. Obtain the parsing success rate and the average signal-to-noise ratio of the paging message within the preset time period on the current serving cell.

Among them, the execution subject of the embodiment of the present invention is the UE.

In the embodiment of the present invention, the UE is camped on the current serving cell. When it is in the RRC standby state or the RRC idle state, if the UE receives a paging message sent by the network device, then the paging message is Parsing, that is, filtering the paging message to determine whether the paging message needs to be processed based on the parsing result. When the parsing is successful, the RRC connection is initiated, thereby switching to the RRC connection state. If the parsing fails, the statistical count is increased by 1.

Optionally, within a preset time period, the UE uses the first counter to count the number of paging messages received to obtain the number of paging messages received or the number of paging messages. At the same time, after each reception When parsing the received paging message, if the parsing is successful, the second counter is used to count the number of parsing successes, that is, the count of the second counter is increased by 1, and when the preset time period is met, the count of the second counter is obtained, and the second counter is obtained. The count of a counter is calculated, and the ratio of the count of the second counter to the count of the first counter is calculated to obtain the parsing success rate of the paging message.

Optionally, the UE locally uses a timer to measure the preset duration. Within the preset duration, each time the UE receives a paging message, the first counter is incremented by 1. If the paging message received this time is If the message is parsed successfully, the count of the second counter is incremented by 1. When the timer is equal to the preset duration, the count of the first counter and the count of the second counter are obtained, and the parsing success rate of the paging message is calculated.

Optionally, the above preset time period can be set by the UE according to actual conditions. For example, the preset time period can be 24 hours.

Optionally, each time a paging message is received, the signal-to-noise ratio value is obtained through the received signal and noise, and the average signal-to-noise ratio is obtained by averaging all the signal-to-noise ratio values obtained within the preset time period. .

202. When the parsing success rate is less than the first preset threshold and/or the average signal-to-noise ratio is less than the second preset threshold, measure at least one neighboring cell to obtain measurement information of each neighboring cell.

In step 201, the parsing success rate and the average signal-to-noise ratio of paging messages within a preset time period are obtained. The parsing success rate and average signal-to-noise ratio of paging messages effectively reflect the service quality of the current serving cell. In the embodiment of the present invention, a first preset threshold and a second preset threshold are set. If the parsing success rate of the paging message is less than the first preset threshold and/or the average signal-to-noise ratio is less than the second preset threshold, This indicates that the service quality of the current serving cell is poor, and neighboring cell measurements need to be triggered to select a cell with better quality to camp on.

Optionally, when the parsing success rate is less than the first preset threshold and/or the average signal-to-noise ratio is less than the second preset threshold, the UE can first obtain information about the surrounding cells, including the cell's identity, frequency, operating bandwidth, and priority. At least one of level, supported service type, current load, additional reference signal, beam scanning information, etc., the UE can then select at least one neighboring cell for measurement based on the information of the surrounding cells.

203. Perform resident cell reselection based on the measurement information of neighboring cells and cell access priority information.

Among them, the measurement information of neighboring cells at least includes RSRQ, RSRP, signal-to-noise ratio value, etc., and then the cell is camped on again based on the measurement information of neighboring cells and cell access priority information, so that it can be combined with RSRQ, RSRP, signal-to-noise ratio, etc., are conducive to selecting higher quality residential cells to improve the communication experience of user equipment.

Optionally, according to the instructions in steps 201 and 202, timing is performed by a timer, and the timer uses a first counter to count the number of received paging messages within a preset time period, and the second counter counts the number of successfully parsed paging messages. The number of calling messages is counted. Within the preset time period, if the ratio of the count of the second counter to the count of the first counter is less than the first preset threshold and the average signal-to-noise ratio is less than the second preset threshold, the cell is reselected. , if the reselection is successful, after switching to the reselected cell for camping, reset the timer, the first counter and the second counter, so that the timer, the first counter and the second counter return to 0, and start again Timing and counting; if there is no reselection and still stays on the current serving cell, the timer, first counter and second counter can also be reset, and restart timing and counting after returning to 0.

By implementing the above embodiments, the user equipment is camped on the current serving cell, and by obtaining the parsing success rate and the average signal-to-noise ratio of the paging message within the preset time period, if the parsing success rate is less than the first preset threshold and/or the signal-to-noise ratio When the average noise ratio is less than the second preset threshold, measure at least one neighboring cell to obtain the measurement information of each neighboring cell, and then further perform reselection of the resident cell based on the measurement information of the neighboring cells and the cell access priority information. By combining The parsing success rate of the paging message of the current serving cell and the average signal-to-noise ratio SNR are used to trigger the neighboring cell measurement and reselection mechanism, which is conducive to selecting a cell with better quality to camp on and improving the user equipment communication experience.

Please refer to Figure 3. Figure 3 is a schematic flow chart of a cell reselection method disclosed in Embodiment 2 of the present invention. As shown in Figure 3, the cell reselection method may include:

301. Obtain the parsing success rate and the average signal-to-noise ratio of the paging message within the preset time period on the current serving cell.

After receiving the paging message, the UE parses the paging message, and the UE can further obtain the signal-to-noise ratio value based on the received signal and noise ratio. Alternatively, after receiving the paging message, the UE parses the paging message and measures the current serving cell and surrounding cells. When measuring the current serving cell, the signal-to-noise ratio value is obtained through the reference signal and noise ratio.

302. When the parsing success rate is less than the first preset threshold and/or the average signal-to-noise ratio is less than the second preset threshold, measure at least one neighboring cell to obtain measurement information of each neighboring cell.

303. Rank at least one neighboring cell as a high-quality cell according to the measurement information of the neighboring cell and the cell access priority information. The measurement information of the neighboring cell includes the reference signal reception quality RSRQ, the reference signal reception power RSRP and the signal-to-noise ratio value.

In the embodiment of the present invention, when the UE is camping on the current serving cell, the service quality of the current serving cell is judged by the parsing success rate and the average signal-to-noise ratio of the paging messages within the preset time period, so as to determine the current serving cell quality in the current serving cell. When the service quality of the serving cell affects the call experience, the measurement of the neighboring cells is triggered. After the measurement information of the neighboring cells is measured, the neighboring cells can be re-ranked according to the measurement information of the neighboring cells and the cell access priority information.

For example, the neighboring cells are cell 1, cell 2 and cell 3 respectively. In the cell access priority information, cell 1 has a higher priority than cell 2, but the measurement information of cell 2 includes reference signal reception quality RSRQ, reference signal reception The power RSRP and signal-to-noise ratio values indicate that the quality of cell 2 is better than that of cell 1. Then, cell 2 is ranked before cell 1 after sorting. That is, cell 2 has a higher priority than cell 1 after sorting.

304. Select a cell to camp on from at least one neighboring cell according to the sorting result.

Among them, after the neighbor cells are sorted as high-quality cells in step 303, a cell is selected from at least one sorted neighbor cell according to the sorting result, and then the current serving cell is switched to the selected cell to camp.

Optionally, selecting a resident cell from at least one neighboring cell for camping based on the sorting result includes: the sorted position of at least one neighboring cell reflects the priority order of the neighboring cells, and obtaining the neighbor with the highest priority according to the priority order. The cell is used as the resident cell, and then the current serving cell is switched to the resident cell for camping, that is, the first neighbor cell after sorting is first selected as the resident cell.

In some optional implementations, selecting a cell to camp on from at least one neighboring cell according to the sorting result includes:

Compare the signal-to-noise ratio values of the sorted first neighboring cell and the current serving cell;

When the signal-to-noise ratio value of the first sorted neighbor cell is greater than the current serving cell, select a neighbor cell with a signal-to-noise ratio value greater than the current serving cell from at least one sorted neighbor cell as a candidate cell;

Select a camping cell from the candidate cells to camp on.

Among them, the position order of the sorted neighboring cells also represents the priority order of the neighboring cells. Therefore, the first neighboring cell after sorting has the highest priority. Generally speaking, the first neighboring cell with the highest priority is selected first. Residency community. In the above embodiment, by first comparing the signal-to-noise ratio value of the sorted first neighboring cell and the current serving cell, if the signal-to-noise ratio value of the first neighboring cell is greater than the signal-to-noise ratio value of the current serving cell, it means that the first neighboring cell The service quality of the cell is better than the current serving cell, and then select all neighboring cells with a signal-to-noise ratio value greater than the current serving cell from the sorted neighboring cells as candidate cells, and then select the highest priority according to the priority order of the candidate cells. The neighboring cell is used as the resident cell. By implementing the above embodiment, it is ensured that the service quality of the reselected cell is better than that of the current serving cell, so that the call service quality can be improved.

Further optionally, when the signal-to-noise ratio value of the first sorted neighbor cell is not greater than the current serving cell, the cell remains stationed in the current serving cell.

In the above embodiment, if the signal-to-noise ratio of the first sorted neighboring cell is less than or equal to the current serving cell, it means that the service quality of the neighboring cell may be worse than that of the current serving cell, then it is enough to continue to stay in the current serving cell.

As another optional implementation, selecting a cell to camp on from at least one neighboring cell according to the sorting result includes:

Compare the measurement information of each sorted neighboring cell and the current serving cell respectively, that is, compare the RSRQ, RSRP and signal-to-noise ratio values of each sorted neighboring cell and the current serving cell respectively to analyze whether there is service based on the measurement information. Neighboring cells with better quality than the current serving cell, if they exist, are selected and used as candidate cells, and then the highest priority cell is selected from the preferred cells as the resident cell to perform cell handover.

In some optional implementations, when completing the reselection, the UE reports a cell type list to the network device. The cell type list includes: the cell type identifier of the cell where the UE detects that it can camp and/or wants to camp, That is, it may be the first few neighboring cells with relatively high priorities after sorting. In addition, when reporting the cell type list, the tracking area TA corresponding to the cell type in the cell type list is also reported. Among them, the UE reports the cell type identifiers of all the cells it sees that it can camp on/or that it wants to camp on. It can report it during the attachment process or location area update or cell type update related process.

305. When the parsing success rate is not less than the first preset threshold and the average signal-to-noise ratio is not less than the second preset threshold, keep camping in the current serving cell.

In step 305, when the parsing success rate is greater than or equal to the first preset threshold and the average signal-to-noise ratio is greater than or equal to the second preset threshold, it means that the quality of the current serving cell is good and the cell remains in the current serving cell.

By implementing the above embodiments, the user equipment is camped on the current serving cell, and by obtaining the parsing success rate and the average signal-to-noise ratio of the paging message within the preset time period, if the parsing success rate is less than the first preset threshold and/or the signal-to-noise ratio The average noise ratio is less than the second preset threshold, measuring at least one neighboring cell to obtain measurement information including RSRQ, RSRP and signal-to-noise ratio value of each neighboring cell, and performing at least one neighboring cell based on the measurement information and cell access priority information. The cells are re-ordered, and then the neighbor cell with the highest priority is selected to camp on based on the sorted priority order, which helps the UE switch to the camped cell with better service quality and improves the user equipment communication experience.
