Description

Target cell determining method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a target cell.

Background

Currently, 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 switched, searching surrounding switchable neighbor cells, then selecting a cell with highest signal strength from the surrounding switchable neighbor cells as a target cell, and switching to the target cell.

However, when the 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, the terminal device is likely to be switched to the target cell which cannot support the important slicing service, so that the important slicing service is interrupted.

Disclosure of Invention

The application provides a target cell determining method and device, which can solve the problem that important slicing service of terminal equipment is interrupted in a switching process.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, the present application provides a method for determining a target cell, the method comprising: the access network equipment acquires the slice priority of at least one slice service of the terminal equipment and the slice priority of the slice service supported by at least one neighbor cell of the serving cell; the access network equipment determines that the slice service with the slice priority being the first slice priority is a target slice service in at least one slice service; the access network equipment determines a set of first cells; the first cell is a neighboring cell supporting a target slice service in at least one neighboring cell; 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.

Based on the above technical solution, according to the target cell determining method provided by the embodiments of the present application, an access network device first obtains a slice priority of at least one slice service of a terminal device, and a slice priority supported by at least one neighboring cell of a serving cell. The access network equipment determines whether the slice service with the first slice priority exists in at least one slice service, and if so, the adjacent cell which can support the target slice service is screened from the at least one adjacent cell to be the first cell. The access network device then determines a target cell from the first set of cells. Therefore, the target cell determined by the access network equipment can support the target slicing service, and the continuity of the target slicing service when the terminal equipment is switched to the target cell is ensured.

In one possible implementation, the access network device determines one of a set of first cells as a target cell. In this implementation manner, 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, determines whether the slice service with the first slice priority exists in the at least one slice service, if so, screens the neighboring cell capable of supporting the target slice service from the at least one neighboring cell as a first cell, if only one of the first cells, determines the first cell as a target cell, so that the determined target cell can support the target slice service, and ensures continuity of the target slice service when the terminal device switches to the target cell

In this implementation manner, 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, determines whether the slice service of the first slice priority exists in the at least one slice service, if not, the access network device determines the target cell in the at least one neighboring cell according to a preset condition, that is, combines the same priority number, the same priority level and the signal strength in the process of determining the target cell, so that the slice service of the terminal device can be continued as much as possible.

In one possible implementation, the preset condition includes at least one of: the number of the same slice services is the largest; the most of the same slice services, and the priority level of the slice services except the same slice service is the highest; the most of the same slice services, the slice services other than the same slice service have the highest priority level and the strongest signal strength. In this implementation manner, it is convenient for the access network device to determine the target cell under the condition that there are a plurality of first cells in the first cell set, so that the determined target cell can better continue the slice service of the terminal device in progress, and can also continue the slice service of the terminal device as much as possible.

Currently, in the handover procedure, in general, the selection of the target cell may 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 supporting the same slice service is used as the selection condition of the target cell.

Scene 1, the signal intensity of the cell is used as the selection condition of the target cell.

The measurement report reported by the terminal device includes, for example, 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 intensities of the three adjacent cells, determining that the signal intensity of the third adjacent cell is highest, and further determining that the third adjacent cell is used as a target cell. In this case, the source access network device will send a handover request to the third neighbor (i.e. the third access network device).

Problems with scenario 1:

when the terminal equipment accesses the source access network equipment and is carrying out an important slicing service, if the signal intensity of the cell is taken as the condition of selecting the target cell, the terminal equipment is likely to be switched to the target cell which cannot support the important slicing service, and the important slicing service is interrupted.

Illustratively, the terminal device access source access network device is doing slice service #1, slice service #2, slice service #3. And determining that the switchable neighbor cells are the first neighbor cell, the second neighbor cell and the third neighbor cell respectively according to the measurement report reported by the terminal equipment, and determining a first slice service list (for example, the first slice service list comprises slice service #1 and slice service # 3), a second slice service list (for example, the second slice service list comprises slice service #1 and slice service # 2) which can be supported by the second neighbor cell and a third slice service list (for example, the third slice service list comprises slice service #2 and slice service # 3) which can be supported by the third neighbor cell respectively. Wherein slice service #1 is an important slice service.

If the target cell is determined only according to the condition 1, comparing the signal strengths of the three adjacent cells, determining that the signal strength of the third adjacent cell is highest, and further determining that the third adjacent cell is the target cell. In this case, the source access network device will send a handover request to the third neighbor (i.e. the third access network device). However, the third neighbor does not support the slice service #1, and switching to the third neighbor causes the slice service #1 to be interrupted.

Scenario 2, the number of supported identical slice services is used as the selection condition of the target cell.

Illustratively, the switchable neighbor cell is determined from the measurement report reported by the terminal device (e.g., the switchable neighbor cell includes a first neighbor cell, a second neighbor cell, and a third neighbor cell). Firstly determining a target slice service list (for example, the target slice service list comprises slice service #1, slice service #2 and slice service # 3) which is carried out by the access source access network device of the terminal device, respectively determining a first slice service list (for example, the first slice service list comprises slice service # 1) which can be supported by a first adjacent cell, a second slice service list (for example, the second slice service list comprises slice service # 2) which can be supported by a second adjacent cell and a third slice service list (for example, the third slice service list comprises slice service #2 and slice service # 3) which can be supported by a third adjacent cell, and comparing the target slice service list with the first slice service list, the second slice service list and the third slice service list respectively to determine that the number of the first adjacent cell supports the same slice service is 1, the number of the second adjacent cell supports the same slice service is 1, and the number of the third adjacent cell supports the same slice service is 2. In this case, the source access network device will send a handover request to the third neighbor (i.e. the third access network device).

Problems with scenario 2:

when the terminal device accesses the source access network device and is carrying out an important slicing service, if only the number of the same slicing services supported is used as the selection condition of the target cell, the terminal device is likely to be switched to the target cell which cannot support the important slicing service, and the important slicing service is interrupted.

In combination with the above example, it is known by comparison that the number of the first neighboring cells supporting the same slice service is 1, the number of the second neighboring cells supporting the same slice service is 1, and the number of the third neighboring cells supporting the same slice service is 2, so that the maximum number of the same slices supported by the third neighboring cells is determined, and the third neighboring cells are determined as target neighboring cells. In this case, the source access network device will send a handover request to the third neighbor (i.e. the third access network device). However, the third neighbor does not support the slice service #1, and switching to the third neighbor causes the slice service #1 to be interrupted.

In order to solve the problems in the prior art, the embodiment of the application provides a target cell determining method, which can solve the problem that important slicing service of terminal equipment is interrupted in a switching process. As shown in fig. 3, the method includes:

S301, the access network equipment acquires the slice priority of at least one slice service of the terminal equipment and the slice priority of the slice service supported by at least one adjacent cell of the service cell.

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

Illustratively, the first slice priority may be represented by 0. The second slice priority may be represented by 1. Unset slice priorities may be indicated by nothing.

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

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

It should be noted that, the access network device may determine, through the measurement report reported by the terminal device, identification information of at least one neighboring cell of the serving cell, and then determine, according to information of each supported slice service interacted when the access network device is started and the identification information of the at least one neighboring cell, priority of all or part of slice services supported by each neighboring cell in the at least one neighboring cell.

Wherein, the information of the slicing service comprises at least one of the following items: slice identification, and slice priority.

S302, the access network equipment determines that the slice service with the slice priority being the first slice priority is the target slice service in at least one slice service.

Example 1, the target slice service is one (e.g., slice service # 1). Example 2, the target slice traffic is multiple (e.g., the target slice traffic includes slice traffic #1, and slice traffic # 2).

Note that, the first slice priority may be a slice priority with the highest slice priority.

Illustratively, the first slice priority may be a slice priority of 0.

S303, the access network equipment determines a set of first cells.

The first cell is a neighboring cell supporting a target slice service in at least one neighboring cell.

In combination with the above example 1, the first cell is a neighboring cell that can support the slice service #1 among the at least one neighboring cell.

In combination with the above example 2, the first cell is a neighbor cell that supports both the slice service #1 and the slice service #2 among the at least one neighbor cell. That is, when the target slice service is plural, the first cell needs to support the plural target slice services.

In addition, when the target slice service is multiple (i.e. slice service #1 and slice service # 2), and there is no neighbor cell supporting the multiple target slice services at the same time in at least one neighbor cell, the access network device sequentially performs screening according to the number of the same slice service, the priority level of the slice service except the same slice service, and the signal strength as conditions in at least one neighbor cell, and determines the target cell. The specific implementation steps of this case can be understood with reference to the following S501-S502, and will not be described here again.

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

It should be noted that, since the target cell is a cell determined from the set of the first cells, the target cell must be a cell supporting the target slice service, so as to ensure continuity of the target slice service in the handover process.

The application provides a target cell determining method, wherein an access network device firstly acquires the slice priority of at least one slice service of a terminal device and the slice priority supported by at least one neighbor cell of a serving cell. The access network equipment determines whether the slice service with the first slice priority exists in at least one slice service, and if so, the adjacent cell which can support the target slice service is screened from the at least one adjacent cell to be the first cell. The access network device then determines a target cell from the first set of cells. Therefore, the target cell determined by the access network equipment can support the target slicing service, and the continuity of the target slicing service when the terminal equipment is switched to the target cell is ensured.

In a possible implementation manner, in conjunction with fig. 3, as shown in fig. 4, S304 may specifically include: one first cell is included in the set of case 1.1 and a plurality of first cells are included in the set of case 1.2. Case 1.1 and case 1.2 are described in detail below:

case 1.1, the set of first cells includes one first cell.

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

S401, the access network equipment determines one first cell in the set of first cells as a target cell.

Illustratively, the terminal device access source access network device is doing slice service #1, slice service #2, slice service #3. The priority of the slice service #1 is the first slice priority (i.e., the slice service #1 is the target slice service). The priority of slice traffic #2 is the second slice priority. The priority of slice traffic #3 is the third slice priority. The neighbor cells in the measurement report reported by the terminal equipment comprise a first neighbor cell, a second neighbor cell and a third neighbor cell. Wherein the first neighbor cell supports slice service #1. The second neighbor supports slice service #2. The third neighbor cell supports slice service #2 and slice service #3. In contrast, only the first neighbor cell supports the slicing service #1, and thus only the first neighbor cell can be the first cell. At this time, the access network device determines the first neighboring cell as a target cell.

The access network equipment firstly acquires the slice priority of at least one slice service of the terminal equipment and the slice priority supported by at least one neighbor cell of the service cell, determines whether the slice service with the first slice priority exists in the at least one slice service, screens neighbor cells capable of supporting the target slice service from the at least one neighbor cell to be first cells if the slice service exists, and determines the first cells to be target cells if the first cells are only one, so that the determined target cells can support the target slice service, and the continuity of the target slice service when the terminal equipment is switched to the target cells is ensured.

Case 1.2, the set of first cells includes a plurality of first cells.

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

S402, the access network equipment determines slice information of each first cell.

Wherein the slice information includes at least one of: the number of identical slice services, the priority level of slice services other than identical slice services, and the signal strength.

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

Illustratively, the at least one slicing service performed by the terminal device access source access network device includes slicing service #1, slicing service #2, and slicing service #3. The 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 traffic is 2.

The priority level of the slice service other than the same slice service refers to a priority level of the slice service other than the same slice service in at least one slice service supported by the first cell.

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

The signal strength is used to characterize the strength of the signal of the first cell.

The signal strength of the first cell A1 is-67 dBm, for example. The signal strength of the other first cell A2 is-75 dBm. In comparison, the signal strength of the first cell A1 is stronger than that of the first cell A2.

S403, the access network equipment determines that the first cell with the slice information meeting the preset condition is a target cell in the set of the first cells.

In a possible implementation manner, the preset condition may specifically include: condition 1, the first cell with the largest number of identical slice traffic is the target cell, condition 2, and condition 3. Conditions 1, 2, and 3 are described in detail below:

the first cell with the largest number of identical slice traffic is the target cell under condition 1.

If the access network device can only determine one first cell in the set of first cells according to the maximum number of the same slices, the access network device determines the first cell as the target cell. In this case, the preset condition may be that the number of identical slice services is the largest.

The at least one slice service performed by the terminal device access source access network device includes: slice traffic #1, slice traffic #2, and slice traffic #3. The priority of the slice service #1 is the first slice priority. The first cell set includes a first cell A1 and a first cell A2. The at least one slice service supported by the first cell A1 includes: slice traffic #1, slice traffic #2, and slice traffic #4. The at least one slice service supported by the first cell A2 includes: slice traffic #1, slice traffic #2. In this case, the number of identical slice traffic of the first cell A1 is 2. The number of identical slice traffic of the first cell A2 is 1. As can be seen from comparison, the number of identical slice traffic of the first cell A1 is higher than the number of identical slice traffic of the first cell A2. Therefore, the access network device can only determine the first cell A1 according to the maximum number of the same slices, and further determine the first cell A1 as the target cell.

The first cell having the highest number of identical slice services and having the highest priority level of slice services other than the identical slice service is the target cell under condition 2.

If the access network device determines that there are more than one first cell in the set of first cells according to the same number of slices, the access network device may determine that one first cell in the plurality of first cells is the target cell according to the highest priority level of the slice service other than the same slice service. In this case, the preset condition may be that the number of identical slice services is the largest and priority levels of slice services other than the identical slice services are the highest. That is, when the access network device cannot determine one cell from the first cell set according to the maximum number of slices, it is necessary to determine, as the target cell, one first cell having the highest priority level of the slice service other than the same slice service from the plurality of first cells having been screened according to the maximum number of slices.

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

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

The slice services supported by the first cell A1 except for the same slice service are: slice service #4. The priority of the slice service #4 is the first slice priority.

The slice services supported by the first cell A2 except for the same slice service are: slice traffic #5. The priority of the slice service #5 is the third slice priority.

In contrast, the slice priority of the slice service #4 is higher than that of the slice service #5, and therefore, the access network apparatus determines one first cell having the highest priority level of the slice services other than the same slice service as the first cell A1. In this case, the first cell A1 is determined as the target cell.

The condition 3, the number of the same slice services is the largest, the priority level of the slice services except the same slice service is the highest, and the first cell with the strongest signal strength is the target cell.

If the access network device has a plurality of first cells determined according to the most number of the same slices in the set of first cells, the access network device can determine the first cell with the strongest signal strength as the target cell according to the signal strength when the access network device has a plurality of first cells determined according to the highest priority level of the slice services other than the same slice service. In this case, the number of identical slice services is the largest, the priority level of slice services other than the identical slice service is the highest, and the signal strength is the strongest. That is, when the access network device cannot determine a cell from the first cell set according to the highest priority level of the same slice number and the slice services other than the same slice service, it is necessary to determine, as the target neighbor cell, the first cell having the highest cell signal strength from among the plurality of first cells screened according to the highest priority level of the same slice number and the slice services other than the same slice service.

The slice services supported by the first cell A1 except for the same slice service are: slice service #4. The priority of the slice service #4 is the third slice priority.

As can be seen from comparison, the slice priority of the slice service #4 is equal to the slice priority of the slice service #5, and thus, the access network device determines that there are two cells (i.e., the first cell A1 and the first cell A2) having the highest priority level of the slice service other than the same slice service.

The signal strength of the first cell A1 is-85 dBm. The signal strength of the first cell A2 is-80 dBm. In contrast, the signal strength of the first cell A2 is higher than that of the first cell A1, so at this time, the access network device determines the first cell A2 as the target cell.

The access network equipment firstly acquires the slice priority of at least one slice service of the terminal equipment and the slice priority supported by at least one adjacent cell of the service cell, determines whether the slice service with the first slice priority exists in the at least one slice service, screens adjacent cells capable of supporting the target slice service from the at least one adjacent cell to be the first cell if the slice service exists, and determines the target cell from the plurality of first cells according to preset conditions if the first cell exists, namely, combines the same priority number, the same priority level and the signal strength in the process of determining the target cell, so that the determined target cell can better continue the slice service in progress of the terminal equipment and can further continue the slice service of the terminal equipment as much as possible.

The case where the first cell is included in the first cell set is described in detail above. In addition, in the process of determining the set of first cells (i.e. S303), the access network device may occur that there is no first cell in the neighboring cell, i.e. there is no first cell in the set of first cells, in which case the access network device may further determine the target cell by the method described in the following S501-S502. As shown in fig. 5, S501 to S502 specifically include:

S501, if the first cell is not included in the set of the first cells, the access network device determines slice information of at least one neighboring cell.

It should be noted that, regarding the number of the same slice services, the priority level of the slice services other than the same slice service, and the description of the signal strength may refer to the explanation of the above section S402, which is not repeated here.

S502, the access network equipment determines that a neighbor cell with the slice information meeting a preset condition is a target cell in at least one neighbor cell.

The specific implementation procedure of S502 is similar to the implementation procedure of S403 described above. Only the set of the first cells in S403 needs to be replaced by at least one neighboring cell in S502, and other implementation manners are similar, which is not described in detail herein.

It should be noted that, for the description of the preset condition, reference may be made to the explanation of the above section S403, which is not repeated here.

The access network equipment firstly acquires the slice priority of at least one slice service of the terminal equipment and the slice priority supported by at least one adjacent cell of the service cell, determines whether the slice service with the first slice priority exists in the at least one slice service, and if the slice service with the first slice priority does not exist, the access network equipment determines the target cell in the at least one adjacent cell according to a preset condition, namely, combines the same priority number, the same priority level and the signal strength in the process of determining the target cell, so that the slice service of the terminal equipment can be continued as much as possible.
