Abstract

Embodiments of the present disclosure relate to dynamical changes in access and mobility policies. According to embodiments, an Application Function entity can request the Access and Mobility related entity to modify the access and mobility policies for a terminal device after the discovery of the Access and Mobility related entity. Alternatively, the Access and Mobility related entity obtains access and mobility policies from a User Data Repository that link traffic of an application on a Session towards to access and mobility policies and configure the AM policy based on a detection of traffic change done under control of a Session Management related entity. Therefore, the access setting and/or the mobility setting can be dynamically changed based on the traffic change in the application.

First claim

What is claimed is:

1. An apparatus comprising:
at least one processor; and
at least one memory storing computer program code of a binding support function, the computer program code, when executed by the at least one processor, causing the binding support function to perform operations, the operations comprising:
receiving, from an Access and Mobility Management policy control entity, a register request indicating an identity of the Access and Mobility Management policy control entity, the Access and Mobility Management policy control entity capable of managing at least one of an access setting or a mobility setting of an application on a terminal device;
receiving, from an Application Function entity, a discovery or subscription request for discovering the Access and Mobility Management policy control entity capable of managing the at least one of the access setting or the mobility setting of the application;
sending, to the Application Function entity, a discovery response or notification indicating an identity of the Access and Mobility Management policy control entity;
receiving, from a fourth entity, a further register request indicating an identity of the fourth entity, the fourth entity capable of having a traffic change in the application being detected;
receiving, from the Access and Mobility Management policy control entity or the Application Function entity, a discovery or subscription request for discovering the fourth entity capable of having the traffic change in the application being detected; and
sending, to the Access and Mobility Management policy control entity or the Application Function entity, a discovery response or notification indicating an identity of the fourth entity capable of having the traffic change in the application being detected.

2. A method, comprising:
receiving, at a binding support function, from an Access and Mobility Management policy control entity, a register request indicating an identity of the Access and Mobility Management policy control entity, the Access and Mobility Management policy control entity capable of managing at least one of an access setting or a mobility setting of an application on a terminal device;
receiving, at the binding support function, from an Application Function entity, a discovery or subscription request for discovering the Access and Mobility Management policy control entity, the Access and Mobility Management policy control entity capable of managing at least one of an access setting or a mobility setting of the application;
sending, by the binding support function, to the Application Function entity, a discovery response or notification indicating an identity of the Access and Mobility Management policy control entity
receiving, at the binding support function, from a fourth entity, a further register request indicating an identity of the fourth entity, the fourth entity capable of having a traffic change in the application being detected;
receiving, at the binding support function, from the Access and Mobility Management policy control entity or the Application Function entity, a discovery or subscription request for discovering the fourth entity capable of having the traffic change in the application being detected; and
sending, by the binding support function, to the Access and Mobility Management policy control entity or the Application Function entity, a discovery response or notification indicating an identity of the fourth entity capable of having a traffic change in the application being detected.

3. A non-transitory computer readable storage medium storing program instructions of a binding support function, the program instructions, when executed by an apparatus, causing the apparatus to perform operations, the operations comprising:
receiving, at the binding support function, from an Access and Mobility Management policy control entity, a register request indicating an identity of the Access and Mobility Management policy control entity, the Access and Mobility Management policy control entity capable of managing at least one of an access setting or a mobility setting of an application on a terminal device;
receiving, at the binding support function, from an Application Function entity, a discovery or subscription request for discovering the Access and Mobility Management policy control entity, the Access and Mobility Management policy control entity capable of managing at least one of an access setting or a mobility setting of the application;
sending, by the binding support function, to the Application Function entity, a discovery response or notification indicating an identity of the Access and Mobility Management policy control entity;
receiving, at the binding support function, from a fourth entity, a further register request indicating an identity of the fourth entity, the fourth entity capable of having a traffic change in the application being detected;
receiving, at the binding support function, from the Access and Mobility Management policy control entity or the Application Function entity, a discovery or subscription request for discovering the fourth entity capable of having the traffic change in the application being detected; and
sending, by the binding support function, to the Access and Mobility Management policy control entity or the Application Function entity, a discovery response or notification indicating an identity of the fourth entity capable of having a traffic change in the application being detected.

4. The non-transitory computer readable storage medium of claim 3 , wherein the fourth entity comprises a Policy control Session Management entity.

5. The apparatus of claim 1 , wherein the fourth entity comprises a Policy control Session Management entity.

6. The method of claim 2 , wherein the fourth entity comprises a Policy control Session Management entity.
