Abstract

This application provides an example group management method, apparatus, and system. The example group management method includes receiving a first group request from an application function network element, where the first group request includes indication information, an external group identifier, and first group information, and where the indication information indicates a group service type, and the external group identifier is a group identifier that is not identified by a network element by a network element inside a core network, in response to that the group service type is creating a group, obtaining an internal group identifier corresponding to the external group identifier, and associating the internal group identifier, the external group identifier, and the first group information, where internal group identifier is a group identifier that is identified by the network element inside the core network.

First claim

What is claimed is:

1. A group management method, comprising:
receiving a first group request from an application function network element, wherein the first group request comprises an external group identifier, and first group information and the external group identifier is a group identifier that is not identified by a network element inside a core network;
in response to determining that the first group request is for creating a group, obtaining an internal group identifier corresponding to the external group identifier, wherein the internal group identifier is a group identifier that is identified by the network element inside the core network; and
associating the internal group identifier, the external group identifier, and the first group information.

2. The group management method according to claim 1 , wherein the first group information comprises first identifiers of one or more group members comprised in the group.

3. The group management method according to claim 1 , comprising:
sending the internal group identifier to an interface network element.

4. The group management method according to claim 2 , comprising:
sending the internal group identifier and the first group information to the one or more group members.

5. A group management method, comprising:
receiving a third group request from an application function network element, wherein the third group request comprises an external group identifier and first group information, and wherein the external group identifier is a group identifier that is not identified by a network element inside a core network;
determining whether an entry of an internal group identifier corresponding to the external group identifier has been stored, wherein the internal group identifier is a group identifier that is identified by the network element inside the core network; and
in response to determining that the entry of the internal group identifier corresponding to the external group identifier has not been stored, sending a second group request to a data network element, wherein the second group request comprises the external group identifier and first identifiers of one or more group members.

6. The group management method according to claim 5 , wherein the first group information comprises at least one of the following information: a data network identifier of a group, slice information of the group, a session type corresponding to the group, or the first identifiers of the one or more group members comprised in the group.

7. A group management apparatus, comprising:
at least one processor;
a communications interface coupled to the at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions including instructions to:
receive, through the communications interface, a first group request from an application function network element, wherein the first group request comprises an external group identifier, and first group information, and the external group identifier is a group identifier that is not identified by a network element inside a core network;
in response to determining that the first group request is for creating a group, obtain an internal group identifier corresponding to the external group identifier, wherein the internal group identifier is a group identifier that is identified by the network element inside the core network; and
associate the internal group identifier, the external group identifier, and the first group information.

8. The group management apparatus according to claim 7 , wherein the first group information comprises first identifiers of one or more group members comprised in the group.

9. The group management apparatus according to claim 7 , wherein the communications interface sends the internal group identifier to an interface network element.

10. The group management apparatus according to claim 7 , wherein the communications interface sends the internal group identifier and the first group information to one or more group members.

11. A group management apparatus, comprising:
at least one processor;
a communications interface coupled to the at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions including instructions to:
receive, through the communications interface, a third group request from an application function network element, wherein the third group request comprises an external group identifier and first group information, and wherein the external group identifier is a group identifier that is not identified by a network element inside a core network;
determining whether an entry of an internal group identifier corresponding to the external group identifier has been stored, wherein the internal group identifier is a group identifier that is identified by the network element inside the core network; and
in response to determining that the entry of the internal group identifier corresponding to the external group identifier has not been stored, send, through the communications interface, a second group request to a data network element, wherein the second group request comprises the external group identifier and first identifiers of one or more group members.

12. The group management apparatus according to claim 11 , wherein the first group information comprises at least one of the following information: a data network identifier of a group, slice information of the group, a session type corresponding to the group, or the first identifiers of the one or more group members comprised in the group.
