Abstract

Apparatuses and methods tor an update service operation tor short message service, SMS, service are disclosed. In one embodiment, a method implemented in access and mobility management function, AMF, node (S 104 ) includes performing an update service operation with a short message service function, SMSF, node to add or remove a first user equipment, UE, context information associated to a first access type, the update service operation indicating to the SMSF node the first access type to add or remove. In some embodiment, a method implemented in a short message service function, SMSF, node (S 106 ) includes performing an update service operation with an access and mobility management, AMF, node to add or remove a first user equipment, UE, context information associated to a first access type, the update service operation indicating to the SMSF node the first access type to add or remove.

Claims (36)

1 . A method implemented in an access and mobility management, AMF, node, the method comprising:

performing a first update service operation with a short message service function, SMSF, node to add a first user equipment, UE, context information associated to a first access type, the first update service operation indicating to the SMSF node the first access type to add when the UE registers in the first access type;

performing a second update service operation with a short message service function, SMSF, node to add a second UE context information associated to a second access type, the second update service operation indicating to the SMSF node the second access type to add when the UE registers in the second access type; and

when the UE deregisters from the first access type, performing a third update service operation to delete the first UE context information associated to the first access type, the third update service operation indicates to the SMSF node the first access type to remove while maintaining the second context information associated to the second access type.

2 . The method of claim 1 , wherein the performing the first update service operation comprises sending a short message service, SMS, service message to the SMSF node, the SMS service message comprising an indication of the first access type to add.

3 . The method of claim 1 , wherein one or more of:

the performing of the first update service operation comprises sending a short message service, SMS, service activate message to add the first UE context information associated to the first access type;

the performing of the second update service operation comprises sending a short message service, SMS, service activate message to add the second UE context information associated to the second access type; and

the performing of the third update service operation comprises sending a short message service, SMS, service update message to remove the first UE context information associated to the first access type.

4 . The method of claim 1 , wherein the first update service operation indicates to the SMSF node further information to add to the first UE context information associated to the first access type.

5 . The method of claim 4 , wherein the further information comprises at least one of a Time Zone, a routing indicator and a unified data management, UDM, group identifier for the UE that is to be added in the first UE context information associated to the first access type.

6 . A method implemented in a short message service function, SMSF, node, the method comprising:

performing a service operation with an access and mobility management, AMF, node to add or remove a first user equipment, UE, context information associated to a first access type, the service operation indicating to the SMSF node the first access type to add or remove; and

add or delete the first user equipment, UE context information associated to the first access type without deleting an existing second UE context information associated with a second access type.

7 . The method of claim 6 , wherein the performing the service operation comprises receiving a short message service, SMS, service message from the AMF node, the SMS service message comprising an indication of the first access type to add or remove.

8 . The method of claim 6 , wherein performing the update service operation comprises:

receiving a short message service, SMS, service activate message to add the first UE context information associated to the first access type; or

receiving a short message service, SMS, service deactivate message to remove the first UE context information associated to the first access type; or

receiving a short message service, SMS, service update message to add or remove the first UE context information associated to the first access type.

9 . The method of claim 6 , wherein the service operation requests the SMSF node to add further information from the first UE context information associated to the first access type.

10 . The method of claim 9 , wherein the further information comprises at least one of a Time Zone, a routing indicator and a unified data management, UDM, group identifier for the UE that is to be added in the first UE context information associated to the first access type.

11 . A system comprising:

an access and mobility management, AMF, node configured to perform a service operation with a short message service function, SMSF, node to:

add a first user equipment, UE, context information associated to a first access type, the service operation indicating to the SMSF node the first access type to add when the UE registers in the first access type; or

delete the first user equipment, UE, context information associated to the first access type, the service operation indicating to the SMSF node the first access type to remove when the UE deregisters from the first access type; and

a short message service function, SMSF, node configured to:

perform the service operation with the access and mobility management, AMF, node to add or remove the first user equipment, UE, context information associated to the first access type, the service operation indicating to the SMSF node the first access type to add or remove; and

add or delete the first user equipment, UE, context information associated to the first access type without deleting an existing second UE context information associated with a second access type.

12 . The system of claim 11 wherein the AMF node and the SMSF node performing the service operation further comprises the AMF node being configured to:

send a short message service, SMS, service activate message to add the first UE context information associated to the first access type; or

send a short message service, SMS, service deactivate message to remove the first UE context information associated to the first access type; or

send a short message service, SMS, service update message to add or remove the first UE context information associated to the first access type, and

the SMSF node being configured to:

receive the short message service, SMS, service activate message to add the first UE context information associated to the first access type; or

receive the short message service, SMS, service deactivate message to remove the first UE context information associated to the first access type; or

receive a short message service, SMS, service update message to add or remove the first UE context information associated to the first access type.
