Alias management method and device

1. An alias management method, comprising:

receiving, by a functional alias management entity, an activation request message from a first client, wherein the activation request message comprises an identity of a user using the first client and an identity of an alias requested to be activated, wherein the identity of the user is different than the identity of the alias;

obtaining, by the functional alias management entity, subscription information of the user based on the identity of the user, wherein the subscription information comprises indication information, and the indication information indicates that the user has an alias activation right; and

in response to the functional alias management entity determining that the indication information indicates that the user has the alias activation right, sending, by the functional alias management entity, an activation response message to the first client, wherein the activation response message comprises the identity of the user and an identity of an alias that is successfully activated, wherein

when the alias requested to be activated is an alias that a plurality of users are allowed to simultaneously activate, and a quantity of users who successfully activate the alias requested to be activated is greater than 0 and less than a maximum activation quantity, the alias that is successfully activated is the alias requested to be activated.

2. The method according to claim 1 , wherein the first client is integrated in a mission critical service client, and the functional alias management entity is integrated in a mission critical service server.

3. The method according to claim 1 , wherein the method further comprises:

storing, by the functional alias management entity, an association relationship between the identity of the user and the alias that is successfully activated.

4. The method according to claim 1 , wherein the method further comprises:

sending, by the functional alias management entity, a notification message to a second client, wherein the notification message notifies the second client that the user successfully activates the alias that is successfully activated.

5. A functional alias management entity, comprising at least one processor coupled with a non-transitory storage medium storing executable instructions; wherein the executable instructions, when executed by the at least one processor, cause the at least one processor to:

receive an activation request message from a first client, wherein the activation request message comprises an identity of a user using the first client and an identity of an alias requested to be activated, wherein the identity of the user is different than the identity of the alias;

obtain subscription information of the user based on the identity of the user, wherein the subscription information comprises indication information, and the indication information indicates that the user has an alias activation right; and

in response to the functional alias management entity determining that the indication information indicates that the user has the alias activation right, send an activation response message to the first client, wherein the activation response message comprises the identity of the user and an identity of an alias that is successfully activated, wherein

when the alias requested to be activated is an alias that a plurality of users are allowed to simultaneously activate, and a quantity of users who successfully activate the alias requested to be activated is greater than 0 and less than a maximum activation quantity, the alias that is successfully activated is the alias requested to be activated.

6. The functional alias management entity according to claim 5 , wherein the first client is integrated in a mission critical service client, and the functional alias management entity is integrated in a mission critical service server.

7. The functional alias management entity according to claim 5 , wherein the executable instructions, when executed by the processor, cause the processor to:

store an association relationship between the identity of the user and the alias that is successfully activated.

8. A non-transitory computer readable storage medium, configured to store a computer program, wherein the computer program comprises instructions which, when executed, cause a computer to perform the following steps:

receiving an activation request message from a first client, wherein the activation request message comprises an identity of a user using the first client and an identity of an alias requested to be activated, wherein the identity of the user is different than the identity of the alias;

obtaining, by the computer, subscription information of the user based on the identity of the user, wherein the subscription information comprises indication information, and the indication information indicates that the user has an alias activation right; and

in response to the computer determining that the indication information indicates that the user has the alias activation right, sending an activation response message to the first client, wherein the activation response message comprises the identity of the user and an identity of an alias that is successfully activated, wherein

when the alias requested to be activated is an alias that a plurality of users are allowed to simultaneously activate, and a quantity of users who successfully activate the alias requested to be activated is greater than 0 and less than a maximum activation quantity, the alias that is successfully activated is the alias requested to be activated.

9. The non-transitory computer readable storage medium according to claim 8 , wherein the first client is integrated in a mission critical service client.

10. The non-transitory computer readable storage medium according to claim 8 , wherein the steps further comprise storing an association relationship between the identity of the user and the alias that is successfully activated.
