## Abstract

Embodiments of the present invention provide a method and a device for associating a user with a group. The method includes: receiving, by a first communications device, a first association request sent by a second communications device, where the first association request includes an identifier of an MCPTT user and identifiers of N MCPTT groups, and N is a positive integer; associating the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user; and sending a first association response to the second communications device, where the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer. In this way, the MCPTT user is associated with the M MCPTT groups that the MCPTT user is interested in.

## Claims

### Claim 1

A system for associating a user with a group, comprising: a first communications device and a second communications device, wherein
the second communications device is configured to: send a first association request to the first communications device, wherein the first association request comprises an identifier of a mission critical push to talk over (MCPTT) user and identifiers of N MCPTT groups, the first association request is used to request to associate the MCPTT user with the N MCPTT groups, and N is an integer greater than or equal to 1;
the first communications device is configured to: receive the first association request from the second communications device; associate the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user, wherein the association subscription information of the MCPTT user is used to indicate an MCPTT group that the MCPTT user can be associated with; and send a first association response to the second communications device, wherein the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer; and
the second communications device is further configured to: receive the first association response from the first communications device.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the first communications device is a network device configured for deployment of a group database; or, the first communications device is a first MCPTT server, and the first MCPTT server is an MCPTT server configured to manage the MCPTT user or is an MCPTT server configured to manage the N MCPTT groups; and
the second communications device is a user equipment (UE).

### Claim 3 (depends on 1)

The system according to claim 1, wherein the first communications device is further configured to:
generate first association information, wherein the first association information is used to indicate an association relationship between the MCPTT user and the M MCPTT groups.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the first communications device is further configured to:
obtain subscription data of the MCPTT user according to the identifier of the MCPTT user; and obtain the association subscription information of the MCPTT user according to the subscription data of the MCPTT user; or
obtain group information of the N MCPTT groups according to the identifiers of the N MCPTT groups; and obtain the association subscription information of the MCPTT user according to the group information of the N MCPTT groups and the identifier of the MCPTT user.

### Claim 5

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program, that when executed performs steps comprising:
receiving a first association request from a second communications device, wherein the first association request comprises an identifier of a mission critical push to talk over (MCPTT) user and identifiers of N MCPTT groups, the first association request is used to request to associate the MCPTT user with the N MCPTT groups, and N is an integer greater than or equal to 1;
associating the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user, wherein the association subscription information of the MCPTT user is used to indicate an MCPTT group that the MCPTT user can be associated with; and
sending a first association response to the second communications device, wherein the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer.

### Claim 6 (depends on 5)

The non-transitory computer readable storage medium according to claim 5, wherein the steps further comprise:
generating first association information, wherein the first association information is used to indicate an association relationship between the MCPTT user and the M MCPTT groups.

### Claim 7 (depends on 5)

The non-transitory computer readable storage medium according to claim 5, wherein the steps further comprise:
obtaining subscription data of the MCPTT user according to the identifier of the MCPTT user; and obtaining the association subscription information of the MCPTT user according to the subscription data of the MCPTT user; or
obtaining group information of the N MCPTT groups according to the identifiers of the N MCPTT groups; and obtaining the association subscription information of the MCPTT user according to the group information of the N MCPTT groups and the identifier of the MCPTT user.

### Claim 8

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program, that when executed performs steps comprising:
sending a first association request to a first communications device, wherein the first association request comprises an identifier of a mission critical push to talk over (MCPTT) user and identifiers of N MCPTT groups, the first association request is used to request to associate the MCPTT user with the N MCPTT groups, and N is an integer greater than or equal to 1; and
receiving a first association response from the first communications device, wherein the first association response is used to indicate that the MCPTT user is successfully associated with M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer.
