[0029] Figure 1 : is a flowchart of a cell replacement method provided in an embodiment of the present application. The cell replacement method may include:

[0031] In some possible implementations of the embodiments of the present application, the terminal device can register a New Radio (NR) or Long Term Evolution (LTE) cell and establish a data bearer. After the terminal device successfully establishes the data bearer, the terminal device can send and receive data. Detect whether the Packet Data Protocol (PDP) connection is in an activated state. When the PDP connection is in an activated state, obtain the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate, the uplink rate, the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell, and the signal quality of the neighboring cell.

[0032] In some possible implementations of the embodiments of the present application, in step 101, the uplink authorization size refers to the size of the network scheduling configured by the network device for the terminal device; the uplink cache data volume refers to the amount of data cached when the terminal device sends data to the network device; the uplink PDCP packet loss rate refers to the ratio of the number of data packets lost when the terminal device sends data to the network device to the total number of data packets sent; the uplink rate is the data sending rate when the terminal device sends data to the network device.

[0033] Step 102: Determine whether the uplink is congested according to the uplink grant size, the uplink buffer data volume, the uplink PDCP packet loss rate and the uplink rate. If yes, execute step 103; if no, end;

[0034] In some possible implementations of the embodiments of the present application, step 102 may include: determining that the uplink is congested when it is determined that the uplink congestion scenario is met based on the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate and the uplink rate; determining that the uplink is not congested when it is determined that the uplink congestion scenario is not met based on the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate and the uplink rate; the uplink congestion scenario includes at least one of the following: an uplink low scheduling scenario, an uplink high packet loss scenario and an uplink low rate scenario.

[0035] In some possible implementations of the embodiments of the present application, before step 102, the cell replacement method provided by the embodiments of the present application may also include: when the uplink authorization size is less than the uplink authorization size threshold and the uplink cache data volume is greater than the uplink cache data volume threshold, determining that the uplink low scheduling scenario is met; when the uplink PDCP packet loss rate is greater than the uplink PDCP packet loss rate threshold, determining that the uplink high packet loss scenario is met; when the uplink rate is less than the uplink rate threshold and the uplink cache data volume is greater than the uplink cache data volume threshold, determining that the uplink low rate scenario is met.

[0036] In some possible implementations of the embodiments of the present application, when the uplink authorization size is small and the uplink cache data volume is large, this scenario is defined as an uplink low scheduling scenario; when the uplink PDCP packet loss rate is large, this scenario is defined as an uplink low rate scenario; when the uplink rate is small and the uplink cache data volume is large, this scenario is defined as an uplink low rate scenario.

[0037] In some possible implementations of the embodiments of the present application, when the uplink authorization size is not less than the uplink authorization size threshold or the uplink cache data volume is not greater than the uplink cache data volume threshold, the uplink low scheduling scenario is not met; when the uplink PDCP packet loss rate is not greater than the uplink PDCP packet loss rate threshold, the uplink high packet loss scenario is not met; when the uplink rate is not less than the uplink rate threshold or the uplink cache data volume is greater than the uplink cache data volume threshold, the uplink low rate scenario is not met.

[0038] In some possible implementations of the embodiments of the present application, when the uplink congestion scenario includes an uplink low scheduling scenario, when the uplink low scheduling scenario is satisfied, the uplink congestion scenario is satisfied, and the uplink congestion is determined at this time; when the uplink low scheduling scenario is not satisfied, the uplink congestion scenario is not satisfied, and it is determined that the uplink is not congested.

[0039] When the uplink congestion scenario includes an uplink high packet loss scenario, when the uplink high packet loss scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when the uplink high packet loss scenario is not met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0040] When the uplink congestion scenario includes an uplink low rate scenario, when the uplink low rate scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when the uplink low rate scenario is not met, the uplink congestion scenario is not met, and the uplink is determined to be not congested.

[0041] When the uplink congestion scenario includes an uplink low scheduling scenario and an uplink high packet loss scenario, when any one of the uplink low scheduling scenario and the uplink high packet loss scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when the uplink low scheduling scenario and the uplink high packet loss scenario are not met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0042] When the uplink congestion scenario includes an uplink low scheduling scenario and an uplink high packet loss scenario, when any one of the uplink low scheduling scenario and the uplink high packet loss scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when neither the uplink low scheduling scenario nor the uplink high packet loss scenario is met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0043] When the uplink congestion scenario includes an uplink low scheduling scenario and an uplink low rate scenario, when any one of the uplink low scheduling scenario and the uplink low rate scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when neither the uplink low scheduling scenario nor the uplink low rate scenario is met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0044] When the uplink congestion scenario includes an uplink low-rate scenario and an uplink high packet loss scenario, when any one of the uplink low-rate scenario and the uplink high packet loss scenario is met, the uplink congestion scenario is met, and the uplink congestion is determined at this time; when neither the uplink low-rate scenario nor the uplink high packet loss scenario is met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0045] When the uplink congestion scenario includes the uplink low scheduling scenario, the uplink high packet loss scenario and the uplink low rate scenario, the uplink congestion scenario is met when any one of the three scenarios is met, and the uplink congestion is determined at this time; when the uplink low scheduling scenario, the uplink high packet loss scenario and the uplink low rate scenario are not met, the uplink congestion scenario is not met, and it is determined that the uplink is not congested.

[0046] Step 103: determining whether the first condition is met according to the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell, and the signal quality of the neighboring cell; if so, executing step 104; if not, ending;

[0047] In some possible implementations of the embodiments of the present application, the first condition may include:

[0048] The signal strength of the serving cell is greater than a first signal strength threshold;

[0049] The signal strength of the neighboring cell is greater than the second signal strength threshold;

[0050] The signal quality of the serving cell is greater than a first signal quality threshold;

[0051] The signal quality of the neighboring cell is greater than the second signal quality threshold.

[0052] In some possible implementations of the embodiments of the present application, when uplink congestion occurs, even if the signal strength of the serving cell is poor, or the signal quality of the serving cell is poor, or the signal strength of the neighboring cell is poor, or the signal quality of the neighboring cell is poor, there is no need to change the cell.

[0053] In the embodiment of the present application, the cell is changed only when the signal strength of the serving cell is large, the signal strength of the neighboring cell is large, the signal quality of the serving cell is good, and the signal quality of the neighboring cell is good. This can avoid cell change failure and can change to a cell with a large signal strength and good signal quality, thereby improving the communication efficiency of electronic equipment.

[0054] In some possible implementations of the embodiments of the present application, a cell change is triggered by a single uplink congestion, which may cause the cell change to be erroneously triggered. Therefore, the cell change may be triggered only when there are multiple uplink congestions. Based on this, the first condition in the embodiments of the present application may also include: the count value of the counter is greater than or equal to the number threshold, wherein the counter is used to record the number of uplink congestions within the first duration.

[0055] In some possible implementations of the embodiments of the present application, a first duration of the timer can be set in advance, and the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate, the uplink rate, the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell, and the signal quality of the neighboring cell are obtained according to a preset data acquisition frequency. Each time the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate, the uplink rate, the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell, and the signal quality of the neighboring cell are obtained, a judgment is made as to whether the uplink is congested. When it is judged that the uplink is congested, the count value of the counter is incremented by 1.

[0056] In some possible implementations of the embodiments of the present application, when the timer reaches the first duration, the timer can be restarted and the counter can be restarted. In this case, the cell replacement is triggered only when the number of uplink congestion within the first duration is greater than or equal to the number threshold and the signal strength of the serving cell is greater than the first signal strength threshold, the signal strength of the neighboring cell is greater than the second signal strength threshold, the signal quality of the serving cell is greater than the first signal quality threshold, and the signal quality of the neighboring cell is greater than the second signal quality threshold.

[0057] Exemplarily, assuming that the timer timing is 1 second and the data acquisition frequency is 10 Hz, that is, the uplink authorization size, uplink cache data volume, uplink PDCP packet loss rate, uplink rate, signal strength of the serving cell, signal quality of the serving cell, signal strength of the neighboring cell and signal quality of the neighboring cell are obtained once every 100 milliseconds. A total of 10 data are obtained within 1 second, and the number threshold is 5.

[0058] If uplink congestion is determined at least 5 times out of 10 and the signal strength of the serving cell is greater than the first signal strength threshold, the signal strength of the neighboring cell is greater than the second signal strength threshold, the signal quality of the serving cell is greater than the first signal quality threshold, and the signal quality of the neighboring cell is greater than the second signal quality threshold, the cell replacement is triggered; if uplink congestion is determined less than 5 times out of 10, the cell replacement is not triggered.

[0059] In some possible implementations of the embodiments of the present application, the counter can be restarted when the uplink is not congested; when the timer reaches the first time, the timer restarts and the counter restarts. In this case, the cell replacement is triggered only when the number of consecutive uplink congestion within the first time is greater than or equal to the number threshold and the signal strength of the serving cell is greater than the first signal strength threshold, the signal strength of the neighboring cell is greater than the second signal strength threshold, the signal quality of the serving cell is greater than the first signal quality threshold, and the signal quality of the neighboring cell is greater than the second signal quality threshold.

[0060] Exemplarily, assuming that the timer timing is 1 second and the data acquisition frequency is 10 Hz, that is, the uplink authorization size, uplink cache data volume, uplink PDCP packet loss rate, uplink rate, signal strength of the serving cell, signal quality of the serving cell, signal strength of the neighboring cell and signal quality of the neighboring cell are obtained once every 100 milliseconds. A total of 10 data are obtained within 1 second, and the number threshold is 5.

[0061] If uplink congestion is determined continuously for at least 5 times out of 10 times and the signal strength of the serving cell is greater than the first signal strength threshold, the signal strength of the neighboring cell is greater than the second signal strength threshold, the signal quality of the serving cell is greater than the first signal quality threshold, and the signal quality of the neighboring cell is greater than the second signal quality threshold, the cell replacement is triggered; if uplink congestion is determined continuously for less than 5 times out of 10 times, the cell replacement is not triggered.

[0062] In some possible implementations of the embodiments of the present application, the various thresholds in the embodiments of the present application can be set according to actual needs.

[0063] In the embodiment of the present application, the cell is changed only when the uplink is congested for multiple times, which can improve the accuracy of cell switching and avoid the occurrence of erroneous cell switching.

[0064] Step 104: triggering a cell change, wherein the cell change includes one of the following: cell switching, cell redirection, and cell reselection.

[0065] In some possible implementations of the embodiments of the present application, the terminal device may send a cell change notification message to the Radio Resource Control (RRC) layer, and the RRC performs a cell change according to a cell change algorithm.

[0066] In an embodiment of the present application, by obtaining the first parameter information, wherein the first parameter information includes the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate, the uplink rate, the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell and the signal quality of the neighboring cell; according to the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate and the uplink rate, determine whether the uplink is congested; in the case of uplink congestion, determine whether the first condition is met according to the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell and the signal quality of the neighboring cell; in the case of meeting the first condition, trigger the cell replacement, wherein the cell replacement includes one of the following items: cell switching, cell redirection, cell reselection. In this way, it is possible to timely determine whether the uplink is congested through the uplink authorization size, the uplink cache data volume, the uplink PDCP packet loss rate and the uplink rate, and then trigger the cell replacement when the uplink is congested and the first condition is met, so that the electronic device can escape from the cell with abnormal communication in time, and the communication efficiency of the electronic device can be improved.

[0070] Step 203: Set the timer duration, data acquisition frequency, and start the timer;

[0071] Step 204: acquiring uplink grant size, uplink buffer data volume, uplink PDCP packet loss rate, uplink rate, serving cell signal strength, serving cell signal quality, neighboring cell signal strength, and neighboring cell signal quality according to the data acquisition frequency;

[0073] Step 206: Determine whether any of the uplink low scheduling scenario, the uplink high packet loss scenario and the uplink low rate scenario is met, if yes, execute step 207, if no, execute step 212;

[0074] Step 207: the count value of the counter is incremented by 1;

[0075] Step 208: Determine whether the first condition is met according to the count value of the counter, the signal strength of the serving cell, the signal quality of the serving cell, the signal strength of the neighboring cell, and the signal quality of the neighboring cell; if yes, execute step 211; if not, execute step 209;

[0076] Step 209: Determine whether the timer duration reaches the set timer duration, if yes, execute step 210, if no, continue to execute step 204;

[0077] Step 210: The timer is reset and step 204 is continued;

[0078] Step 211: Triggering cell change;

[0079] Step 212: The count value of the counter is restored to the initial value 0, and the process continues with step 204.

[0080] The present application embodiment does not elaborate on the various steps included in the cell change process. For details, please refer to Figure 1 Description of the illustrated embodiment.
