Abstract

A SIP (session initiation protocol) service activation abstraction layer that provides a unified interface to upper layer applications for discovering, establishing, and managing the QoS connectivity. In one implementation, this is IP Multimedia Subsystem-centric, further supporting applications that utilize SIP for session control. This capability extends to the data card universe allowing UMTS data card vendors to establish concurrent QoS-based sessions using multiple primary PDP (packet data protocol) contexts based on a set of SIP triggers, further allowing applications running on a computing system to transparently utilize the established pipes based on the individual QoS requirements.

Claims

1. A system, comprising;

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

authenticating an application that communicates with a network device from a domain;

facilitating a network session between the application and a network resource of the network device via an interface;

facilitating attainment of a defined quality of service for the network session;

after the attainment of the defined quality of service for the network session, facilitating access by another application to the network resource via the network device;

disabling the network resource in response to the network resource being determined to be no longer requested; and

terminating access of the application to the network resource independent of a termination of another network session for the other application that is concurrent with the network session.

2. The system of claim 1, wherein the operations further comprise enabling the application to discover the interface via a uniform abstraction layer that is associated with a packet data protocol context established for a predetermined quality of service.

3. The system of claim 2, wherein the operations further comprise managing the packet data protocol context.

4. The system of claim 1, wherein the operations further comprise determining an identity associated with the application.

5. The system of claim 1, wherein the interface includes a service activation layer and exposes a set of services using the service activation layer.

6. The system of claim 1, wherein the domain is at least one of a user equipment domain, a terrestrial radio access network domain, or a core network domain.

7. The system of claim 1, wherein the domain comprises at least one of a user services identity module or a mobile equipment domain.

8. A method, comprising:

authenticating, by a system including a processor, an application that communicates with a network device from a domain;

facilitating, by the system, a network session between the application and a network resource of the network device via a interface; and

enabling, by the system, access to a defined quality of service for the network session;

facilitating, by the system, access by another application to the network resource, via the network device, after attaining the defined quality of service for the network session; and

disabling, by the system, the network resource in response to the network resource being determined to be no longer requested; and

terminating, by the system, access of the application to the network resource independent of a termination of another network session for the other application that is concurrent with the network session.

9. The method of claim 8, further comprising enabling, by the system, the application to discover the interface via a uniform abstraction layer that is associated with a packet data protocol context established for a predetermined quality of service.

10. The method of claim 9, further comprising performing, by the system, management of the packet data protocol context.

11. The method of claim 8, further comprising determining, by the system, an identity associated with the application.

12. The method of claim 8, further comprising managing, by the system, multiple domains including a user equipment domain, a terrestrial radio access network domain, and a core network domain.

13. The method of claim 8, wherein the enabling the access to the defined quality of service is based on analyzing a quality of service level in a home location register.

14. The method of claim 13, further comprising negotiating, by the system, a new packet data protocol context in response to a request for a new quality of service level.

15. A computer-readable storage device storing executable instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:

authenticating an application that communicates with a network device from a domain;

facilitating a network session between the application and a network resource of the network device via an interface; and

enabling access to a defined quality of service for the network session;

facilitating access by another application to the network resource, via the network device, after attaining the defined quality of service for the network session; and

disabling the network resource in response to the network resource no longer being requested and terminating access of the application to the network resource independent of a termination of another network session for the other application that is concurrent with the network session.

16. The computer-readable storage device of claim 15, wherein the operations further comprise:

enabling the application to discover the interface via a uniform abstraction layer that is associated with a packet data protocol context established for a predetermined quality of service.

17. The computer-readable storage device of claim 16, wherein the operations further comprise:

performing admission control and management of the packet data protocol context.

18. The computer-readable storage device of claim 15, wherein the operations further comprise:

determining an identity associated with the application.

19. The computer-readable storage device of claim 15, wherein the operations further comprise:

managing multiple domains including a user equipment domain, a terrestrial radio access network domain, and a core network domain.

20. The computer-readable storage device of claim 15, wherein the operations further comprise:

negotiating a new packet data protocol context in response to a request for a new quality of service level.
