Abstract

A communication method, a communication apparatus, and system are disclosed. The method includes a data analytics network element (NWDAF) sends a first request to a storage function network element. The first request includes delay information and/or indication information. The indication information indicates that the NWDAF supports analyzing data within a specified delay. The first request is used to store the delay information and/or the indication information into the storage function network element. The data analytics network element receives a first response from the storage function network element. The first response indicates, to the data analytics network element, that the delay information and/or the indication information are/is successfully stored.

First claim

What is claimed is:

1. A communication method, comprising:
receiving, by a storage function network element, a first request from a data analytics network element, wherein the first request comprises at least one of delay information or indication information, wherein the delay information comprises one or more of the following information: a collection delay of first data, an inference delay of a data analytics result of the first data, or a transfer delay of the data analytics result, wherein the indication information indicates that the data analytics network element supports analyzing the first data within a specified delay, and wherein the at least one of the delay information or the indication information is stored into the storage function network element based on the first request; and
sending, by the storage function network element, a first response to the data analytics network element, wherein the first response indicates that the at least one of the delay information or the indication information is successfully stored.

2. The method according to claim 1 , further comprising:
receiving, by the storage function network element, a seventh request from a fourth network function network element, wherein the seventh request requests information of the data analytics network element; and
sending, by the storage function network element, a seventh response to the fourth network function network element, wherein the seventh response comprises information of one or more data analytics network elements.

3. The method according to claim 2 , wherein the seventh request further comprises a data analytics delay requirement of the fourth network function network element, and the method further comprises:
determining, by the storage function network element based on at least one piece of delay information corresponding to at least one data analytics network element, the one or more data analytics network elements that meet the data analytics delay requirement; and
wherein sending, by the storage function network element, the seventh response to the fourth network function network element comprises:
sending, by the storage function network element, the seventh response to the fourth network function network element, wherein the seventh response comprises the information of the one or more data analytics network elements that meet the data analytics delay requirement.

4. The method according to claim 2 , wherein sending, by the storage function network element, the seventh response to the fourth network function network element comprises:
determining, by the storage function network element, the one or more data analytics network elements that support analyzing data within the specified delay; and
sending, by the storage function network element, the seventh response to the fourth network function network element, wherein the seventh response comprises the information of the one or more data analytics network elements that support analyzing data within the specified delay.

5. A communication method, comprising:
sending, by a fourth network function network element, a seventh request to a storage function network element, wherein the seventh request requests information of a data analytics network element;
receiving, by the fourth network function network element, a seventh response sent by the storage function network element, wherein the seventh response comprises information of one or more data analytics network elements, and the one or more data analytics network elements respectively correspond to delay information; and
determining, by the fourth network function network element from the one or more data analytics network elements, a target data analytics network element that meets a data analytics delay requirement of the fourth network function network element.

6. The method according to claim 5 , wherein determining, by the fourth network function network element from the one or more data analytics network elements, the target data analytics network element that meets the data analytics delay requirement of the fourth network function network element comprises:
determining, by the fourth network function network element from the seventh response, the delay information respectively corresponding to the one or more data analytics network elements; and
determining, by the fourth network function network element, the target data analytics network element based on the delay information respectively corresponding to the one or more data analytics network elements and the data analytics delay requirement.

7. The method according to claim 5 , wherein determining, by the fourth network function network element, the target data analytics network element based on the seventh response comprises:
sending, by the fourth network function network element, the data analytics delay requirement to the one or more data analytics network elements separately;
receiving, by the fourth network function network element, a delay matching result sent by at least one data analytics network element that meets the data analytics delay requirement; and
determining, by the fourth network function network element, the target data analytics network element from the at least one data analytics network element that sends the delay matching result.

8. A communication apparatus, comprising:
at least one processor; and
a non-transitory computer-readable storage medium storing a program to be executed by the at least one processor, the program including instructions to:
receive a first request from a data analytics network element, wherein the first request comprises at least one of delay information or indication information, wherein the delay information comprises one or more of a collection delay of first data, an inference delay of a data analytics result of the first data, or a transfer delay of the data analytics result, wherein the indication information indicates that the communication apparatus supports analyzing data within a specified delay, and wherein the at least one of the delay information or the indication information is stored into a storage function network element based on the first request; and
send a first response to the data analytics network element, wherein the first response indicates, to the communication apparatus, that the at least one of the delay information or the indication information is successfully stored.

9. The apparatus according to claim 8 , wherein the instructions further include instructions to:
send a second request to a first network function network element, wherein the second request requests the first data;
receive a seventh request from a fourth network function network element, wherein the seventh request requests information of the data analytics network element; and
send a seventh response to the fourth network function network element, wherein the seventh response comprises information of one or more data analytics network elements.

10. The apparatus according to claim 9 , wherein the seventh request further comprises a data analytics delay requirement of the fourth network function network element, and the instructions further include instructions to:
determine, based on at least one piece of delay information corresponding to at least one data analytics network element, the one or more data analytics network elements that meet the data analytics delay requirement; and
wherein sending the seventh response to the fourth network function network element comprises:
sending the seventh response to the fourth network function network element, wherein the seventh response comprises information of the one or more data analytics network elements that meet the data analytics delay
