Lawful interception using service-based interfaces in communication systems
In a service provider network of a given communication system configured to support lawful interception functionality, one or more service-based interfaces are provisioned to enable interaction between one or more lawful interception-specific elements and one or more intercepting control elements. In one or more further implementations, methods provide for provisioning an interworking function specific for lawful interception functionality. The interworking function can be configured to support both service-based interfaces and point-to-point interfaces across a control plane and/or a user plane of the service provider network, as needed.
1. A method comprising:
in a service provider network of a given communication system configured to support lawful interception functionality, provisioning one or more service-based interfaces to enable interaction between one or more lawful interception-specific elements and two or more intercepting control elements, wherein the one or more service-based interfaces enable direct interaction with each of the two or more intercepting control elements in the service provider network.
2. The method of claim 1 , wherein the one or more lawful interception-specific elements comprise an administration function and one or more delivery functions.
3. The method of claim 2 , wherein the administration function and the one or more delivery functions are operatively coupled to a monitoring entity.
4. The method of claim 1 , wherein the two or more intercepting control elements comprise two or more network functions of the service provider network.
5. The method of claim 4 , wherein at least one of the two or more network functions comprises a network function associated with at least one of a control plane and a user plane of the service provider network.
6. The method of claim 1 , further comprising provisioning an interworking function specific for lawful interception functionality, wherein the interworking function comprises:
a service-based interface to interact with the two or more intercepting control elements associated with a control plane of the service provider network; and
a point-to-point interface to interact with at least a portion of the one or more lawful interception-specific elements.
7. The method of claim 1 , further comprising provisioning an interworking function specific for lawful interception functionality, wherein the interworking function comprises:
a service-based interface to interact with the two or more intercepting control elements associated with a control plane and a user plane of the service provider network; and
a point-to-point interface to interact with at least a portion of the one or more lawful interception-specific elements.
8. The method of claim 1 , wherein the one or more lawful interception-specific elements are configured to support the one or more service-based interfaces.
9. The method of claim 1 , further comprising provisioning an interworking function specific for lawful interception functionality, wherein the interworking function comprises:
a service-based interface to interact with the two or more intercepting control elements associated with a control plane and a user plane of the service provider network; and
another service-based interface to interact with at least a portion of the one or more lawful interception-specific elements.
10. The method of claim 1 , wherein the two or more intercepting control elements each comprise separate service-based interfaces wherein one of the service-based interfaces is dedicated to the lawful interception functionality.
11. The method of claim 1 , further comprising provisioning one or more point-to-point interfaces to enable reference-point based interaction between the one or more lawful interception-specific elements and the two or more intercepting control elements, in addition to the one or more service-based interfaces.
12. The method of claim 1 , wherein the communication system comprises a 5G system.
13. Apparatus comprising:
in a service provider network of a given communication system configured to support lawful interception functionality, one or more service-based interfaces provisioned to enable interaction between one or more lawful interception-specific elements and two or more intercepting control elements, wherein the one or more service-based interfaces enable direct interaction with each of the two or more intercepting control elements in the service provider network.
14. The apparatus of claim 13 , further comprising:
an interworking function specific for lawful interception functionality, wherein the interworking function comprises:
a service-based interface to interact with the two or more intercepting control elements associated with a control plane of the service provider network; and
a point-to-point interface to interact with at least a portion of the one or more lawful interception-specific elements.
15. The apparatus of claim 13 , wherein the one or more lawful interception-specific elements comprise an administration function and one or more delivery functions.
16. The apparatus of claim 13 , wherein the two or more intercepting control elements comprise two or more network functions of the service provider network.
17. An article of manufacture comprising a non-transitory computer-readable storage medium having embodied therein executable program code that when executed by a processor causes the processor to perform step of:
in a service provider network of a given communication system configured to support lawful interception functionality, provisioning one or more service-based interfaces to enable interaction between one or more lawful interception-specific elements and two or more intercepting control elements, wherein the one or more service-based interfaces enable direct interaction with each of the two or more intercepting control elements in the service provider network.
18. The article of claim 17 , further configured to:
provision an interworking function specific for lawful interception functionality, wherein the interworking function comprises:
a service-based interface to interact with the two or more intercepting control elements associated with a control plane of the service provider network; and
a point-to-point interface to interact with at least a portion of the one or more lawful interception-specific elements.
19. The article of claim 17 , wherein the one or more lawful interception-specific elements comprise an administration function and one or more delivery functions.
20. The article of claim 17 , wherein the two or more intercepting control elements comprise one or more network functions of the service provider network.
