Please refer to fig. 1, which is a flowchart illustrating a cell handover method according to an embodiment of the present application. The method can be applied to terminal equipment. As shown in fig. 1, the method may include steps 1100 to S1300, which are described in detail below.
Step S1100, when the set triggering condition is satisfied, determining an adjustment value of the set parameter according to an initial parameter value of the set parameter corresponding to the cell switching event.
The cell switching event is an a5 event, that is, in a service currently running by the terminal device, for example, in a video call process, when a video screen splash and pause phenomenon occurs, it indicates that the signal quality of the serving cell where the terminal device is located is poor, and at this time, the terminal device can switch the serving cell where the terminal device is located to an adjacent cell with good signal quality by triggering an a5 event, so that the video screen splash and pause phenomenon is alleviated.
In this embodiment, the triggering of the cell switching event needs to satisfy a setting condition, where the setting condition includes a first setting condition and a second setting condition. Wherein the first setting condition includes: the first Reference Signal received Power RSRP1(Reference Signal Receiving Power) of the serving cell where the terminal device is located is smaller than the initial parameter value a1 of the first setting parameter a, that is, RSRP1< a 1. The second setting condition includes: the second reference signal received power (RSRP 2) of the target adjacent cell of the serving cell where the terminal device is located is greater than the initial parameter value b1 of the second set parameter b, namely RSRP2> b 1. The initial parameter value a1 of the first setting parameter a and the initial parameter value b1 of the second setting parameter b are both issued by the network side equipment, and the initial parameter value a1 of the first setting parameter a is smaller than the initial parameter value b1 of the second setting parameter b.
The setting parameters include the above first setting parameter and the above second setting parameter. The initial parameter value of the first setting parameter a is a 1. The initial parameter value of the second setting parameter b is b 1.
The setting of the trigger condition includes at least one of: the current running business of the terminal equipment is abnormal, and the receiving power of the first reference signal is higher than the initial parameter value of the first set parameter. Or, the current service running by the terminal device is abnormal, and the receiving power of the second reference signal is lower than the initial parameter value of the second setting parameter. The first parameter threshold and the second parameter threshold may be values set according to actual application scenarios and actual requirements.
In one example, the setting triggering event includes that the service currently running by the terminal device is abnormal, and the first reference signal received power is higher than the initial parameter value of the first setting parameter. When the step S1100 is executed and the setting triggering condition is satisfied, before determining the adjustment value of the setting parameter according to the initial parameter value of the setting parameter corresponding to the cell handover event, the method further includes: and acquiring the first reference signal receiving power of the serving cell in which the terminal equipment is positioned.
Here, when the setting triggering condition is satisfied in step S1100, determining the adjustment value of the setting parameter according to the initial parameter value of the setting parameter corresponding to the cell handover event may further include: when the current running service of the terminal equipment is abnormal and the receiving power of the first reference signal is higher than the initial parameter value of the first setting parameter, determining the intermediate parameter value of the first setting parameter according to the receiving power of the first reference signal and the initial parameter value of the first setting parameter; and then determining the adjusting value of the first setting parameter according to the intermediate parameter value of the first setting parameter and the initial parameter value of the first setting parameter.
In this example, when the current service of the terminal device is abnormal, for example, the video call is abnormal, and the first reference signal received power RSRP1 is higher than the initial parameter value a1 of the first setting parameter a of the a5 event, the terminal device cannot be handed over to the target neighboring cell. Here, the terminal device may calculate a first difference Δ 1 between the first reference signal power RSRP1 of the serving cell where the terminal device is located and the initial parameter value a1 of the first setting parameter a of the a5 event, that is, Δ 1 is RSRP1-a 1. The sum of the first difference Δ 1 and the initial parameter value a1 of the first setting parameter a is then calculated as the adjustment value a2 of the first setting parameter, i.e. a2 ═ a1+ Δ 1.
In one example, the set triggering condition includes that the service currently running by the terminal device is abnormal, and the received power of the second reference signal is lower than the initial parameter value of the second set parameter. When the step S1100 is executed and the setting triggering condition is satisfied, before determining the adjustment value of the setting parameter according to the initial parameter value of the setting parameter corresponding to the cell handover event, the method further includes: and acquiring the second reference signal receiving power of a target adjacent cell of the serving cell where the terminal equipment is located.
Here, when the setting triggering condition is satisfied in step S1100, determining the adjustment value of the setting parameter according to the initial parameter value of the setting parameter corresponding to the cell handover event may further include: when the current service running by the terminal equipment is abnormal and the receiving power of the second reference signal is lower than the initial parameter value of the second setting parameter, determining the intermediate parameter value of the second setting parameter according to the receiving power of the second reference signal and the initial parameter value of the second setting parameter; and then determining an adjusting value of the second setting parameter according to the intermediate parameter value of the second setting parameter and the initial parameter value of the second setting parameter.
In this example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, and the received power of the second reference signal is lower than the initial parameter value b1 of the second setting parameter b of the event a5, the terminal device cannot be handed over to the target neighboring cell. Here, the terminal device may first calculate a second difference Δ 2 between the second reference signal power RSRP2 of the target neighboring cell and the initial parameter value b1 of the second setting parameter b of the a5 event, that is, Δ 2 is b1-RSRP 2. A third difference between the initial parameter value b1 of the second setting parameter b and the second difference Δ 2 is then calculated as the adjusted value b2 of the second setting parameter, i.e. b 2-b 1- Δ 2.
In one example, the setting triggering event includes that the service currently running by the terminal device is abnormal, and the first reference signal received power is higher than an initial parameter value of the first setting parameter, and the second reference signal received power is lower than an initial parameter value of the second setting parameter. Here, the determining the adjustment value of the setting parameter according to the first parameter value of the setting parameter corresponding to the cell handover event in step S1100 may further include:
determining an intermediate parameter value of the first setting parameter according to the first reference signal receiving power and the initial parameter value of the first setting parameter, and determining an adjustment value of the first setting parameter according to the intermediate parameter value of the first setting parameter and the initial parameter value of the first setting parameter. And the number of the first and second groups,
and determining an intermediate parameter value of the second setting parameter according to the second reference signal receiving power and the initial parameter value of the second setting parameter, and determining an adjustment value of the second setting parameter according to the intermediate parameter value of the second setting parameter and the initial parameter value of the second setting parameter.
For how to determine the adjustment value of the first setting parameter and the adjustment value of the second setting parameter, reference may be made to the above description, and details of this embodiment are not repeated herein.
When the set triggering condition is met, after the adjustment value of the set parameter is determined according to the initial parameter value of the set parameter corresponding to the cell switching event, entering:
step S1200, sending the parameter adjustment request to the network side device, so that the network side device determines a target parameter value of the set parameter according to the parameter adjustment request.
The parameter adjustment request carries an adjustment value and an adjustment mode.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, and the first reference signal received power is higher than the initial parameter value a1 of the first setting parameter a of the a5 event, the terminal device cannot be handed over to the target neighboring cell. At this time, the initial parameter value of the first setting parameter of the a5 event needs to be increased.
In this example, the parameter adjustment request may be a request to increase an initial parameter value of the first setting parameter to be greater than an adjustment value of the first setting parameter. The adjusting mode is to increase the initial parameter value of the first setting parameter.
For example, after determining that the adjustment value a2 of the first setting parameter is a1+ Δ 1 according to the above step S1100, the terminal device may send a request to the network-side device to increase the initial parameter value of the first setting parameter to be greater than a2, and after receiving the request, the network-side device may increase the initial parameter value a1 of the first setting parameter to be greater than any value of the adjustment value a2 of the first setting parameter, so as to obtain the target parameter value a3 of the first setting parameter.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, and the second reference signal received power is lower than the initial parameter value b1 of the second setting parameter b of the a5 event, the terminal device cannot be switched to the target neighboring cell. At this time, the initial parameter value of the second setting parameter of the a5 event needs to be lowered.
In this example, the parameter adjustment request may be a request to reduce the initial parameter value of the second setting parameter to be smaller than the adjustment value of the second setting parameter. The adjustment mode may be to decrease the initial parameter value of the second setting.
For example, after determining that the adjustment value b2 of the second setting parameter is b1- Δ 2 according to the above step S2100, the terminal device may send a request to the network-side device to decrease the initial parameter value of the second setting parameter to be less than b2, and after receiving the request, the network-side device may decrease the initial parameter value b1 of the second setting parameter to be any value less than the adjustment value b2 of the second setting parameter, so as to obtain the target parameter value b3 of the second setting parameter.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, and the first reference signal received power is higher than the initial parameter value a1 of the first setting parameter a of the a5 event, and the second reference signal received power is lower than the initial parameter value b1 of the second setting parameter b of the a5 event, the terminal device cannot be handed over to the target neighboring cell. At this time, it is necessary to increase the initial parameter value of the first set parameter of the a5 event and decrease the initial parameter value of the second set parameter of the a5 event.
In this example, the parameter adjustment request may be a request to increase an initial parameter value of the first setting parameter to be larger than an adjustment value of the first setting parameter and to decrease an initial parameter value of the second setting parameter to be smaller than an adjustment value of the second setting parameter. The adjusting mode is to increase the initial parameter value of the first setting parameter and decrease the initial parameter value of the second setting parameter.
For example, after determining the adjustment value a2 of the first setting parameter as a1+ Δ 1 and determining the adjustment value b2 of the second setting parameter as b1- Δ 2 according to the above step S1100, the terminal device may send a request to the network side device to increase the initial parameter value of the first setting parameter to be greater than a2 and decrease the initial parameter value of the second setting parameter to be less than b 2. After receiving the request, the network side device may increase the initial parameter value a1 of the first setting parameter to any value greater than the adjustment value a2 of the first setting parameter to obtain the target parameter value a3 of the first setting parameter, and decrease the initial parameter value b1 of the second setting parameter to any value less than the adjustment value b2 of the second setting parameter to obtain the target parameter value b3 of the second setting parameter.
After a parameter adjustment request is sent to a network side device so that the network side device determines a target parameter value of the set parameter according to the parameter adjustment request, entering:
step 1300, receiving a target parameter value issued by the network side device, and triggering a cell switching event according to the target parameter value to enable the terminal device to switch to a target neighbor cell.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, and the first reference signal received power is higher than the initial parameter value a1 of the first setting parameter of the a5 event, the terminal device cannot be switched to the target neighbor cell. At this time, the network side device increases the initial parameter value a1 of the first setting parameter of the a5 event to be greater than a2 (where a1+ Δ 1) to obtain a target parameter value A3, and as the target parameter value A3 meets RSRP1< A3 and RSRP2> b1, the triggering condition of the a5 event is met, and at this time, the a5 event is triggered to cause the terminal device to switch from the serving cell where the terminal device is located to the target neighbor cell.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, the second reference signal received power is lower than the initial parameter value b1 of the second setting parameter of the a5 event, so that the terminal device cannot be switched to the target neighbor cell. At this time, the network side device reduces the initial parameter value b1 of the second setting parameter of the a5 event to be less than b2 (where b2 is b1- Δ 2) to obtain a target parameter value b3, and since the target parameter value b3 satisfies RSRP2> b3 and RSRP1< a1, the triggering condition of the a5 event is satisfied, and at this time, the a5 event is triggered, so that the terminal device is switched from the serving cell where the terminal device is located to the target neighbor cell.
In one example, when the service currently running by the terminal device is abnormal, for example, the video call is abnormal, the first reference signal received power is higher than the initial parameter value a1 of the first set parameter of the a5 event, and the second reference signal received power is lower than the initial parameter value b1 of the second set parameter of the a5 event, so that the terminal device cannot be handed over to the target neighbor cell. At this time, the network side device increases the initial parameter value a1 of the first setting parameter of the a5 event to be greater than a2 (where a1+ Δ 1) to obtain a target parameter value A3, and decreases the initial parameter value b1 of the second setting parameter of the a5 event to be less than b2 (where b2 is b1- Δ 2) to obtain a target parameter value b 3. Since the target parameter value A3 satisfies RSRP1< A3 and the target parameter value b2 satisfies RSRP2> b3, so as to satisfy the trigger condition of the a5 event, at this time, the a5 event is triggered to cause the terminal device to switch from the serving cell to the target neighbor cell.
According to the embodiment of the disclosure, in the video call process, when the set triggering condition is met, the terminal device sends a parameter adjustment request to the network side device, the network side device reconfigures the parameter value of the set parameter of the triggering cell switching event, namely the a5 event, and sends the reconfigured parameter value of the set parameter of the a5 event to the terminal device, so that the terminal device can trigger the a5 event to switch the serving cell where the terminal device is located to the target neighbor cell with better signal quality, thereby achieving the purpose of improving the video screen splash and pause phenomenon in the video call process.
In an embodiment, before obtaining the second reference signal received power of the target neighboring cell of the serving cell in which the terminal device is located, the cell handover method of the present disclosure further includes the following steps S1110 to S1120:
step S1110, M neighbor cells of the serving cell are obtained.
M is an integer greater than or equal to 2.
In this embodiment, the terminal device may search a plurality of neighboring cells of the current serving cell, and obtain the second reference signal received power of each neighboring cell.
For example, the terminal device searches for the neighboring cell 1, the neighboring cell 2, and the neighboring cell 3, and simultaneously obtains the second reference signal received power RSRP21 of the neighboring cell 1, the second reference signal received power RSRP22 of the neighboring cell 2, and the second reference signal received power RSRP23 of the neighboring cell 3.
Step S1120, determining a target neighbor cell from the M neighbor cells according to the priorities of the M neighbor cells.
In this embodiment, after the second reference signal received powers of the M neighboring cells are obtained, the second reference signal received powers of the M neighboring cells may be sorted in a descending order, and the priorities of the M neighboring cells are determined according to a result of the descending order, for example, the closer the order is, the higher the priority is. Here, the neighbor cell with the highest priority may be selected as the target neighbor cell.
Continuing with the above example, since the second reference signal received power RSRP21 of neighbor cell 1 is greater than the second reference signal received power RSRP22 of neighbor cell 2, the second reference signal received power RSRP22 of neighbor cell 2 is greater than the second reference signal received power RSRP23 of neighbor cell 3. The priority of the adjacent cell 1 is higher than that of the adjacent cell 2, the priority of the adjacent cell 2 is higher than that of the adjacent cell 3, and the adjacent cell 1 is taken as a target adjacent cell.
According to the embodiment, the neighboring cell with the best signal quality is selected as the target neighboring cell, and when the cell handover event is triggered, the terminal device switches the current serving cell to the target neighboring cell, so as to further improve the video screen splash and pause phenomenon.
Please refer to fig. 2, which is a flowchart illustrating another cell handover method according to an embodiment of the present application. The method can be applied to network side equipment. As shown in fig. 2, the method may include steps 2100 to S2300, which will be described in detail below.
In step S2100, a parameter adjustment request sent by the terminal device is received.
The parameter adjustment request carries an adjustment value and an adjustment mode of a set parameter of a cell handover event.
The setting parameters include the above first setting parameter and second setting parameter.
In one example, the parameter adjustment request may be a request to increase an initial parameter value of the first set parameter to be greater than an adjusted value of the first set parameter. The adjusting mode is to increase the initial parameter value of the first setting parameter.
When the abnormal service currently running by the terminal equipment, such as the abnormal video call, occurs, and the first reference signal received power is higher than the initial parameter value a1 of the first setting parameter of the a5 event, the terminal equipment cannot be switched to the target neighbor cell. At this time, the terminal device sends a request to the network-side device to increase the initial parameter value a1 of the first setting parameter to be greater than the adjustment value a 2.
In one example, the parameter adjustment request may be a request to reduce an initial parameter value of the second setting parameter to less than an adjusted value of the second setting parameter. The adjustment mode may be to decrease the initial parameter value of the second setting.
When the service currently running by the terminal equipment is abnormal, for example, the video call is abnormal, and the second reference signal received power is lower than the initial parameter value b1 of the second setting parameter of the a5 event, the terminal equipment cannot be switched to the target neighbor cell. At this time, the terminal device sends a request to the network-side device to reduce the initial parameter value of the second setting parameter to be less than the adjustment value b 2.
In one example, the parameter adjustment request may be a request to increase an initial parameter value of a first setting parameter to a value greater than the adjustment value of the first setting parameter and to decrease an initial parameter value of a second setting parameter to a value less than the adjustment value of the second setting parameter. The adjusting mode is to increase the initial parameter value of the first setting parameter and decrease the initial parameter value of the second setting parameter.
When the terminal equipment is in an abnormal state in the currently running service, for example, the video call is in an abnormal state, and the first reference signal received power is higher than the initial parameter value a1 of the first set parameter of the a5 event, and the second reference signal received power is lower than the initial parameter value b1 of the second set parameter of the a5 event, the terminal equipment cannot be switched to the target neighbor cell. At this time, the terminal device sends a request to the network-side device to increase the initial parameter value of the first setting parameter to be greater than the adjustment value a2, and decrease the initial parameter value b1 of the second setting parameter to be less than the adjustment value b2 of the second setting parameter.
Step S2200 is to determine a target parameter value of the setting parameter according to the parameter adjustment request.
In one example, the determining the target parameter value of the setting parameter according to the parameter adjustment request in step S2200 may further include: and increasing the initial parameter value of the first setting parameter according to the adjustment mode and the adjustment value of the first setting parameter to obtain the target parameter value of the first setting parameter.
In this example, when the network side device receives a request for increasing the initial parameter value of the first setting parameter of the cell handover event to be greater than the adjustment value of the first setting parameter, the initial parameter value a1 of the first setting parameter may be increased to any value greater than a2, so as to obtain the target parameter value a3 of the first setting parameter.
In one example, the determining the target parameter value of the setting parameter according to the parameter adjustment request in step S2200 may further include: and reducing the initial parameter value of the second setting parameter according to the adjustment mode and the adjustment value of the second setting parameter to obtain the target parameter value of the second setting parameter.
In this example, when the network side device receives a request to decrease the initial parameter value of the second setting parameter of the cell handover event to be smaller than the adjustment value of the second setting parameter, the initial parameter value b1 of the second setting parameter may be decreased to any value smaller than b2, so as to obtain the target parameter value b3 of the second setting parameter.
In one example, the determining the target parameter value of the setting parameter according to the parameter adjustment request in step S2200 may further include: according to the adjustment mode and the adjustment value of the first setting parameter, increasing the initial parameter value of the first setting parameter to obtain a target parameter value of the first setting parameter; and reducing the initial parameter value of the second setting parameter according to the adjustment mode and the adjustment value of the second setting parameter to obtain the target parameter value of the second setting parameter.
In this example, when the network side device receives a request to increase the initial parameter value of the first setting parameter of the cell handover event to be greater than the adjustment value of the first setting parameter and decrease the initial parameter value of the second setting parameter to be less than the adjustment value of the second setting parameter, the initial parameter value a1 of the first setting parameter may be increased to any value greater than the adjustment value a2 to obtain the target parameter value a3 of the first setting parameter, and the initial parameter value b1 of the second setting parameter may be decreased to any value less than b2 to obtain the target parameter value b3 of the second setting parameter.
Step 2300, issuing the target parameter value to the terminal device, so that the terminal device triggers a cell switching event according to the target parameter value to switch to the target neighboring cell.
In an example, the network side device increases the initial parameter value a1 of the first setting parameter of the a5 event to be greater than a2 (where a1+ Δ 1) to obtain a target parameter value a3, and issues the target parameter value a3 to the terminal device. Since the target parameter value A3 satisfies RSRP1< A3 and RSRP2> b1, thereby satisfying the triggering condition of the a5 event, the a5 event is triggered to cause the terminal device to switch from the serving cell to the target neighbor cell.
In an example, after the network side device reduces the initial parameter value b1 of the second setting parameter of the a5 event to be smaller than b2 (where b2 is b1- Δ 2) to obtain the target parameter value b3, the network side device issues the target parameter value b3 to the terminal device. Since the target parameter value b3 satisfies RSRP2> b3 and RSRP1< a1, thereby satisfying the triggering condition of the a5 event, the a5 event is triggered to cause the terminal device to switch from the serving cell to the target neighbor cell.
In one example, the network side device increases the initial parameter value a1 of the first setting parameter of the a5 event to be larger than a2 (where a1+ Δ 1) to obtain a target parameter value A3, decreases the initial parameter value b1 of the second setting parameter of the a5 event to be smaller than b2 (where b2 ═ b1- Δ 2) to obtain a target parameter value b3, and sends the target parameter value A3 and the target parameter value b3 to the terminal device. The target parameter value A3 meets RSRP1< A3 and the target parameter value b2 meets RSRP2> b3, so that the triggering condition of the A5 event is met, and at the moment, the A5 event is triggered to ensure that the terminal equipment is switched from the serving cell to the target neighbor cell
According to the embodiment of the disclosure, after receiving a first request of a terminal device, a network side device may reconfigure a parameter value of a setting parameter triggering an a5 event, and send the reconfigured parameter value of the setting parameter of the a5 event to the terminal device, so that the terminal device can trigger an a5 event to switch a serving cell of the terminal device to a target neighboring cell with better signal quality, thereby achieving an improvement of a video splash screen stuck phenomenon in a video call process.
