Abstract

This application provides a communication method, a communication apparatus, a device, and a communication system. A data analytics network element determines a service quality analytics result for a target terminal device, and sends the service quality analytics result to an access network element. After receiving the service quality analytics result, the access network element may perform handover decision on the target terminal device based on the service quality analytics result.

First claim

What is claimed is:

1. A communication method, comprising:
obtaining, by an access network element, a service quality analytics result for a target terminal device from a data analytics network element, wherein the service quality analytics result corresponds to a first service quality of at least one service of the target terminal device and is sent when a second service quality indicated by an updated service quality analytics result does not meet a preset condition, the updated service quality result is determined based on an updated network parameter that is to be used for adjusting a corresponding parameter of the target terminal device; and
performing, by the access network element, a handover decision on the target terminal device based on the service quality analytics result corresponding to the first service quality of the at least one service of the target terminal device.

2. The method according to claim 1 , wherein performing the handover decision comprises:
determining, by the access network element, to perform cell handover on the target terminal device when the service quality analytics result meets a first preset condition; and
performing, by the access network element, cell handover on the target terminal device.

3. The method according to claim 1 , wherein performing the handover decision comprises:
determining, by the access network element, to perform cell handover on the target terminal device when the service quality analytics result meets a first preset condition and signal quality of a cell in which the target terminal device is located meets or exceeds a second preset condition.

4. The method according to claim 1 , wherein the service quality analytics result comprises a first service quality analytics result and a second service quality analytics result for the target terminal device, the method further comprising:
determining, by the access network element, first priority information corresponding to the first service quality analytics result and second priority information corresponding to the second service quality analytics result; and
performing the handover decision on the target terminal device based on the service quality analytics result comprises:
performing, the handover decision on the target terminal device based on the first service quality analytics result, the first priority information corresponding to the first service quality analytics result, the second service quality analytics result, and the second priority information corresponding to the second service quality analytics result.

5. The method according to claim 1 , wherein the method further comprises:
reporting, by the access network element to the data analytics network element, an access network parameter value that can be met by the access network element, wherein the access network parameter value is used to generate the service quality analytics result.

6. The method according to claim 1 , wherein the obtaining, by an access network element, a service quality analytics result for a target terminal device from a data analytics network element comprises:
sending, by the access network element, a service quality analytics request to the data analytics network element to obtain the service quality analytics result from the data analytics network element; and
receiving, by the access network element, the service quality analytics result from the data analytics network element in response to the service quality analytics request.

7. The method according to claim 6 , wherein the sending of the service quality analytics request to the data analytics network element comprises:
sending, by the access network element to the data analytics network element, a service quality analytics request for the target terminal device when the access network element receives a measurement report reported by the target terminal device; or
sending, by the access network element to the data analytics network element, a service quality analytics request for the target terminal device when a measurement report received by the access network element indicates that the signal quality of the cell in which the target terminal device is located meets a third preset condition.

8. The method according to claim 6 , wherein the service quality analytics request comprises indication information to request a service quality analytics result corresponding to an online service of the target terminal device.

9. The method according to claim 1 , further comprising:
determining, by the data analytics network element, the service quality analytics result for the target terminal device; and
sending, by the data analytics network element, the service quality analytics result to the access network element.

10. The method according to claim 9 , the method further comprising:
sending, by the data analytics network element, first indication information to the access network element, the first indication information indicating that the service quality analytics result is a service quality analytics result corresponding to an online service of the target terminal device.

11. The communication method according to claim 1 , wherein the service quality analytics result is the updated service quality analytics result or an original service quality analytics result.

12. An apparatus, comprising at least one processor and a non-transitory memory, wherein the at least one processor is coupled to the non-transitory memory storing computer instructions that, when executed by the at least one processor, cause the apparatus to:
obtain a service quality analytics result for a target terminal device from a data analytics network element, wherein the service quality analytics result corresponds to a first service quality of at least one service of the target terminal device and is sent when a second service quality indicated by an updated service quality analytics result does not meet a preset condition, the updated service quality result is determined based on an updated network parameter that is to be used for adjusting a corresponding parameter of the target terminal device; and
perform a handover decision on the target terminal device based on the service quality analytics result corresponding to the first service quality of the at least one service of the target terminal device.

13. The apparatus according to claim 12 , wherein the instructions, when executed by the at least one processor, cause the apparatus to:
determine to perform cell handover on the target terminal device when the service quality analytics result meets a first preset condition; and
the instructions, upon execution by the at least one processor, cause the apparatus to perform cell handover on the target terminal device.

14. The apparatus according to claim 12 , wherein the instructions, when executed by the at least one processor, cause the apparatus to:
determine to perform cell handover on the target terminal device when the service quality analytics result meets a first preset condition and signal quality of a cell in which the target terminal device is located meets a second preset condition.

15. The apparatus according to claim 12 , wherein the service quality analytics result comprises a first service quality analytics result and a second service quality analytics result for the target terminal device and the instructions, when executed by the at least one processor, cause the apparatus to:
determine first priority information corresponding to the first service quality analytics result and second priority information corresponding to the second service quality analytics resu
