Method and device for determining a target cell

technical field

The present application relates to the field of communication technologies, and in particular to a method and device for determining a target cell.

Background technique

At present, in the handover process, the signal strength of a cell is generally used as a condition for selecting a target cell. The specific process is that when the terminal equipment needs to be handed over, it first searches the neighboring cells that can be handed over, and then selects the cell with the highest signal strength among the neighboring cells that can be handed over as the target cell, and performs handover to the target cell.

However, when the terminal equipment access source access network equipment is performing an important slicing service, if only the signal strength of the cell is used as the condition for selecting the target cell, it is very likely that the terminal equipment will be handed over to a network that cannot support the above important services. The target cell of the slicing service, thus causing the above-mentioned important slicing service to be interrupted.

At present, in the handover process, under normal circumstances, the selection of the target cell can be applied to scenario 1, where the signal strength of the cell is used as the selection condition of the target cell, and scenario 2, where the number of services that support the same slice is used as the selection of the target cell condition.

Scenario 1. The signal strength of the cell is used as the selection condition of the target cell.

Exemplarily, the measurement report reported by the terminal device includes the signal strength of the first neighboring cell, the signal strength of the second neighboring cell, and the signal strength of the third neighboring cell. Comparing the signal strengths of the above three neighboring cells, it is determined that the signal strength of the third neighboring cell is the highest, and then the third neighboring cell is determined as the target cell. In this case, the source access network device will send a handover request to the third neighboring cell (that is, the third access network device).

Problems in Scenario 1:

When a terminal device accesses the source access network device and is performing an important slicing service, if only the signal strength of the cell is used as the condition for selecting the target cell, it is very likely that the terminal device will switch to a position that cannot support the above-mentioned important slicing service the target cell, resulting in the interruption of the above-mentioned important slice services.

Exemplarily, the terminal device access source access network device is performing slice service #1, slice service #2, and slice service #3. According to the measurement report reported by the terminal device, it is determined that the switchable adjacent cells are the first adjacent cell, the second adjacent cell, and the third adjacent cell, and then respectively determine the first slice service list that the first adjacent cell can support (for example, , the first slice service list includes: slice service #1, slice service #3), the second slice service list supported by the second adjacent cell (for example, the second slice service list includes: slice service #1, slice service service #2), and a list of supported third slice services of the third neighboring cell (for example, the third slice service list includes: slice service #2 and slice service #3). Among them, slice service #1 is an important slice service.

If the target cell is determined only according to the above condition 1, compare the signal strengths of the above three neighboring cells, determine that the signal strength of the third neighboring cell is the highest, and then determine the third neighboring cell as the target cell. In this case, the source access network device will send a handover request to the third neighboring cell (that is, the third access network device). However, the third adjacent cell does not support the slice service #1, and switching to the third adjacent cell will cause the slice service #1 to be interrupted.

Scenario 2: The number of services that support the same slice is used as the selection condition for the target cell.

Exemplarily, the switchable neighboring cell is determined from the measurement report reported by the terminal device (for example, the switchable neighboring cell includes: a first neighboring cell, a second neighboring cell, and a third neighboring cell). First determine the target slice service list that the terminal device accesses the source access network device (for example, the target slice service list includes slice service #1, slice service #2, and slice service #3), and then determine the first neighboring cell respectively Supportable first slice service list (for example, the first slice service list includes: slice service #1), the second slice service list that the second neighboring cell can support (for example, the second slice service list includes: slice service #2), and the third list of slice services that can be supported by the third adjacent cell (for example, the third slice service list includes: slice service #2, slice service #3), and then the target slice service list and Comparing the first slice service list, the second slice service list, and the third slice service list, it can be seen that the number of the same slice service supported by the first adjacent cell is 1, the number of the same slice service supported by the second adjacent cell is 1, and the number of the same slice service supported by the second adjacent cell is 1. The number of services supported by the same slice in the three neighboring cells is 2. Therefore, it is determined that the number of the same slices supported by the third neighboring cell is the largest, and then the third neighboring cell is determined as the target neighboring cell. In this case, the source access network device will send a handover request to the third neighboring cell (that is, the third access network device).

Problems in Scenario 2:

When a terminal device accesses the source access network device and is performing an important slice service, if only the number of supported slice services is used as the selection condition for the target cell, it is very likely that the terminal device will switch to a network that cannot support the above-mentioned The target cell of the important slicing service, thus causing the above-mentioned important slicing service to be interrupted.

Combining the above example, the comparison shows that the number of services supported by the same slice in the first adjacent cell is 1, the number of services supported by the same slice in the second adjacent cell is 1, and the number of services supported by the same slice in the third adjacent cell is 2. Therefore, determine the The number of identical slices supported by the three adjacent cells is the largest, and the third adjacent cell is determined as the target adjacent cell. In this case, the source access network device will send a handover request to the third neighboring cell (that is, the third access network device). However, the third adjacent cell does not support the slice service #1, and switching to the third adjacent cell will cause the slice service #1 to be interrupted.

In order to solve the above-mentioned problems in the prior art, the embodiment of the present application proposes a method for determining a target cell, which can solve the problem that the important slice service of the terminal device is interrupted during the handover process. As shown in Figure 3, the method includes:

S301. The access network device obtains the slice priority of at least one slice service of the terminal device, and the slice priority of the slice service supported by at least one neighboring cell of the serving cell.

Wherein, the slice priority may include: a first slice priority, a second slice priority, and an unset slice priority. The first slice priority is higher than the second slice priority, and the second slice priority is higher than the unset slice priority.

Exemplarily, the first slice priority may be represented by 0. The second slice priority can be represented by 1. Unset slice priority can be indicated by None.

It should be noted that the foregoing is only an exemplary description of the slice priority, and the slice priority may also include other levels of slice priority (for example, the third slice priority), which is not limited in this application.

In a possible implementation manner, at least one slicing service may be all or part of slicing services performed by the terminal device in the current access network device.

It should be pointed out that the access network device can determine the identification information of at least one neighboring cell of the serving cell through the measurement report reported by the terminal device, and then based on the information of the slice services that the access network device interacts with each other when opening the station, and the above-mentioned The identification information of the at least one neighboring cell respectively determines the priority of all or part of the slice services supported by each neighboring cell in the at least one neighboring cell.

Wherein, the information of the slice service includes at least one of the following items: slice identifier, and slice priority.

S302. The access network device determines that among at least one slice service, the slice service whose slice priority is the first slice priority is the target slice service.

In Example 1, there is one target slice service (for example, slice service #1). Example 2, there are multiple target slice services (for example, the target slice service includes: slice service #1 and slice service #2).

It should be noted that the first slice priority may be the slice priority with the highest slice priority.

Exemplarily, the first slice priority may be slice priority 0.

S303. The access network device determines a set of first cells.

Wherein, the first cell is a neighboring cell supporting the target slice service among at least one neighboring cell.

With reference to the above example 1, the first cell is a neighboring cell that can support slice service #1 among at least one neighboring cell.

With reference to the above example 2, the first cell is at least one neighboring cell that supports slice service #1 and slice service #2 at the same time. That is to say, when there are multiple target slice services, the first cell needs to support the above multiple target slice services.

In addition, when there are multiple target slice services (that is, slice service #1 and slice service #2), and at least one neighboring cell does not have a neighboring cell that supports the above-mentioned multiple target slice services at the same time, the access network device will In at least one neighboring cell, the target cell is determined according to the number of services of the same slice, priority levels of services other than the services of the same slice, and signal strength as conditions. The specific implementation steps of this situation can be understood with reference to the following S501-S502, and will not be repeated here.

S304. If the set of first cells includes one or more first cells, the access network device determines a target cell from the set of first cells.

It should be noted that since the target cell is a cell determined from the set of first cells, the target cell must be a cell supporting the target slice service, thereby ensuring the continuity of the target slice service during the handover process.

The present application provides a method for determining a target cell. The access network device first obtains the slice priority of at least one slice service of the terminal device and the slice priority supported by at least one neighboring cell of the serving cell. The access network device determines whether there is a slice service with the first slice priority in at least one slice service, and if so, selects a neighbor cell that can support the target slice service from the at least one neighbor cell as the first cell. The access network device then determines the target cell from the first set of cells. In this way, the target cell determined by the access network device can support the target slice service, which ensures the continuity of the target slice service when the terminal device switches to the target cell.

In a possible implementation manner, referring to FIG. 3 , as shown in FIG. 4 , the above S304 may specifically include: case 1.1, the set of first cells includes a first cell, and case 1.2, the set of first cells includes Multiple first cells. Case 1.1 and case 1.2 are described in detail as follows:

Case 1.1. The set of first cells includes a first cell.

In case 1.1, the access network device determines the target cell through the following S401.

S401. The access network device determines a first cell in a set of first cells as a target cell.

Exemplarily, the terminal device access source access network device is performing slice service #1, slice service #2, and slice service #3. Wherein, the priority of the slice service #1 is the first slice priority (that is, the slice service #1 is the target slice service). The priority of slice service #2 is the second slice priority. The priority of slice service #3 is the third slice priority. The neighboring cells in the measurement report reported by the terminal device include a first neighboring cell, a second neighboring cell, and a third neighboring cell. Wherein, the first neighboring cell supports slice service #1. The second neighboring cell supports slice service #2. The third neighboring cell supports slice service #2 and slice service #3. It can be seen from the comparison that only the first neighboring cell supports slice service #1, so only the first neighboring cell can be the first cell. At this time, the access network device determines that the first neighboring cell is the target cell.

This application provides a method for determining a target cell. The access network device first obtains the slice priority of at least one slice service of the terminal device and the slice priority supported by at least one neighboring cell of the serving cell, and determines whether the at least one slice service There is a slice service with the first slice priority. If it exists, select the neighbor cell that can support the target slice service from the above at least one neighbor cell as the first cell. If there is only one first cell, determine the first cell It is the target cell, so that the determined target cell can support the target slice service, which ensures the continuity of the target slice service when the terminal device switches to the target cell.

In case 1.2, the set of first cells includes multiple first cells.

In case 1.2, the access network device determines the target cell through the following S402-S403.

S402. The access network device determines slice information of each first cell.

Wherein, the slice information includes at least one of the following items: the number of services of the same slice, the priority levels of services other than the services of the same slice, and signal strength.

It should be noted that the same number of slice services refers to the number of the same slice services among at least one slice service supported by the first cell and at least one slice service performed by the terminal device access source access network device.

Exemplarily, the at least one slice service performed by the terminal device accessing the source access network device includes slice service #1, slice service #2, and slice service #3. At least one slice service supported by the first cell includes slice service #1, slice service #2, and slice service #4. In this case, the number of identical slice services is two.

It should be noted that the priority level of the slice service other than the same slice service refers to the priority level of other slice services except the same slice service in at least one slice service supported by the first cell.

Exemplarily, the at least one slice service performed by the terminal device accessing the source access network device includes slice service #1, slice service #2, and slice service #3. The priority of the above slice service #1 is the first slice priority. The priority of slice service #2 is the second slice priority. The priority of slice service #3 is the third slice priority. At least one slice service supported by the first cell includes slice service #1, slice service #2, and slice service #4. It can be seen from the comparison that slice service #1 and slice service #2 are the same slice service, and slice service #4 is a slice service other than the same slice service. In this case, the priority level of slice traffic other than the same slice traffic is the priority of slice traffic #4.

It should be noted that the signal strength is used to characterize the strength of the signal of the first cell.

Exemplarily, the signal strength of the first cell A1 is -67dBm. The signal strength of another first cell A2 is -75dBm. It can be seen from the comparison that the signal strength of the first cell A1 is stronger than the signal strength of the first cell A2.

S403. The access network device determines that in the set of first cells, the first cell whose slice information satisfies a preset condition is the target cell.

In a possible implementation manner, the preset conditions may specifically include: condition 1, the first cell with the largest number of services in the same slice is the target cell, condition 2, and condition 3. Condition 1, condition 2, and condition 3 are described in detail as follows:

Condition 1. The first cell with the largest number of services in the same slice is the target cell.

It should be noted that if the access network device has the largest number of identical slices in the set of first cells and can only determine one first cell, the access network device determines that the first cell is the target cell. In this case, the preset condition may be that the number of services of the same slice is the largest.

Exemplarily, the at least one slicing service performed by the terminal device accessing the source access network device includes: slicing service #1, slicing service #2, and slicing service #3. The priority of the above slice service #1 is the first slice priority. The first set of cells includes the first cell A1 and the first cell A2. At least one slice service supported by the first cell A1 includes: slice service #1, slice service #2, and slice service #4. At least one slice service supported by the first cell A2 includes: slice service #1 and slice service #2. In this case, the number of services of the same slice in the first cell A1 is two. The number of services of the same slice in the first cell A2 is 1. It can be seen from the comparison that the number of services of the same slice in the first cell A1 is higher than the number of services of the same slice in the first cell A2. Therefore, the access network device can only determine the first cell A1 according to the largest number of identical slices, and then determine the first cell A1 as the target cell.

Condition 2: The first cell with the largest number of services of the same slice and the highest priority level of services other than the services of the same slice is the target cell.

It should be noted that if the access network device has the largest number of slices based on the same slice in the set of the first cell, and there are more than one determined first cells, the access network device then The priority level of the service is the highest, and one first cell among the plurality of first cells may be determined as the target cell. In this case, the preset condition may be that the number of services of the same slice is the largest, and the priority level of services other than the services of the same slice is the highest. That is to say, when the access network device has the largest number of the same slices and cannot determine a cell from the first set of cells, it needs to determine the highest priority level of slice services other than the same slice service. Among the plurality of first cells screened out with the largest number of the same slices, the first cell with the highest priority level of slice services other than the same slice service is determined as the target cell.

Exemplarily, the at least one slice service performed by the terminal device accessing the source access network device includes slice service #1, slice service #2, and slice service #3. The first cell set includes the first cell A1, the first cell A2, and the first cell A3. At least one slice service supported by the first cell A1 includes slice service #1, slice service #2, and slice service #4. At least one slice service supported by the first cell A2 includes slice service #1, slice service #2, and slice service #5. At least one slice service supported by the first cell A3 includes slice service #1 and slice service #2. In this case, the number of the same slice services of the first cell A1 and the first cell A2 is two.

The slicing priorities of the above three slicing services performed by the terminal device accessing the source access network device are respectively: the priority of the above slicing service #1 is the first slicing priority. The priority of the above slice service #2 is the second slice priority. The priority of the above slice service #3 is the third slice priority.

The slice service other than the same slice service supported by the first cell A1 is: slice service #4. The priority of the above slice service #4 is the first slice priority.

The slice service other than the same slice service supported by the first cell A2 is: slice service #5. The priority of the above slice service #5 is the third slice priority.

The comparison shows that the slice priority of the slice service #4 is higher than the slice priority of the slice service #5. Therefore, the access network device determines that the first cell with the highest priority level of the slice service other than the same slice service is the first cell. A residential area A1. In this case, the first cell A1 is determined to be the target cell.

Condition 3: The number of services with the same slice is the largest, the priority of slice services other than the same slice service is the highest, and the first cell with the strongest signal strength is the target cell.

It should be noted that if the access network device has the largest number of slices based on the same slice in the first cell set, and there are multiple first cells determined, the access network device will then use slice services other than the same slice service If there are more than one determined first cell, the access network device may determine the first cell with the strongest signal strength as the target cell according to the signal strength. In this case, the number of services of the same slice is the largest, and the services of slices other than the services of the same slice have the highest priority level and the strongest signal strength. That is to say, when the access network device cannot determine a cell from the first set of cells according to the largest number of the same slices and the highest priority level of the slice services other than the same slice service, it needs to be based on the signal strength of the cell , from among the multiple first cells that have been screened out according to the largest number of the same slices and the highest priority levels of the slice services other than the same slice service, determine the first cell with the highest cell signal strength as the target neighboring cell.

Exemplarily, the at least one slice service performed by the terminal device accessing the source access network device includes slice service #1, slice service #2, and slice service #3. The first cell set includes the first cell A1, the first cell A2, and the first cell A3. At least one slice service supported by the first cell A1 includes slice service #1, slice service #2, and slice service #4. At least one slice service supported by the first cell A2 includes slice service #1, slice service #2, and slice service #5. At least one slice service supported by the first cell A3 includes slice service #1 and slice service #2. In this case, the number of the same slice services of the first cell A1 and the first cell A2 is two.

The slicing priorities of the above three slicing services performed by the terminal device accessing the source access network device are respectively: the priority of the above slicing service #1 is the first slicing priority. The priority of the above slice service #2 is the second slice priority. The priority of the above slice service #3 is the third slice priority.

The slice service other than the same slice service supported by the first cell A1 is: slice service #4. The priority of the above slice service #4 is the third slice priority.

The slice service other than the same slice service supported by the first cell A2 is: slice service #5. The priority of the above slice service #5 is the third slice priority.

The comparison shows that the slice priority of the slice service #4 is equal to the slice priority of the slice service #5, therefore, the access network device determines that there are two cells with the highest priority level of the slice service other than the same slice service (that is, the No. A cell A1 and a first cell A2).

The signal strength of the first cell A1 is -85dBm. The signal strength of the first cell A2 is -80 dBm. The comparison shows that the signal strength of the first cell A2 is higher than the signal strength of the first cell A1, therefore, at this time, the access network device determines that the first cell A2 is the target cell.

This application provides a method for determining a target cell. The access network device first obtains the slice priority of at least one slice service of the terminal device and the slice priority supported by at least one neighboring cell of the serving cell, and determines whether the at least one slice service There is a slice service with the first slice priority. If it exists, select the neighbor cell that can support the target slice service from the above at least one neighbor cell as the first cell. If there are multiple first cells, the access network device Determine the target cell among the plurality of first cells according to preset conditions, that is, in the process of determining the target cell, combine the three of the same priority number, the same priority level, and the signal strength, so that the determined target The cell can better continue the ongoing slicing service of the terminal device, and can also continue the slicing service of the terminal device as much as possible.

Above, the case that the first cell set includes the first cell has been described in detail. In addition, during the process of the access network device determining the set of first cells (that is, S303), it may occur that the first cell does not exist in the neighboring cell, that is, the first cell does not exist in the set of first cells. In this case , the access network device may further determine the target cell through the methods described in S501-S502 below. As shown in Figure 5, S501-S502 specifically include:

S501. If the set of first cells does not include the first cell, the access network device determines slice information of at least one neighboring cell.

Wherein, the slice information includes at least one of the following items: the number of services of the same slice, the priority levels of services other than the services of the same slice, and signal strength.

It should be noted that, regarding the number of services of the same slice, the priority levels of services other than the services of the same slice, and the description of the signal strength, please refer to the explanation of the above-mentioned part S402, which will not be repeated here.

S502. The access network device determines at least one neighboring cell whose slice information satisfies a preset condition as the target cell.

This application provides a method for determining a target cell.

If there is no slice service, the access network device will determine the target cell in the above at least one neighboring cell according to the preset conditions, that is, in the process of determining the target cell, combine the same priority number , the same priority level, and signal strength, so that the slicing service of the terminal device can be continued as much as possible.
