Abstract

System(s) and method(s) are provided to manage packet data protocol (PDP) contexts upon cellular-to-femto handover, wherein femto network has disparate capabilities to support applications with distinct access point names (APNs) and quality of service (QoS) profiles. Based at least on activity factors of applications associated with PDP contexts, a QoS-based ranking of PDP contexts, and subscriber input, cellular network platform selects active PDP contexts to retain and suspend upon handover. A group of active PDP contexts is handed off in accordance with femto coverage capability, with remaining active PDP contexts suspended during handover. When a suspended PDP context, and application associated therewith, is resumed through femto coverage, a PDP context modification is conducted with a new APN and the application is routed to a corresponding femto gateway node and application server. Additionally, femto network platform performs a radio access bearer reconfiguration to meet QoS requirements of the resumed PDP context.

Claims

1. A method, comprising:

receiving, by a mobile device comprising a processor, an indication of a selection of a first set of active packet data protocol contexts and a second set of active packet data protocol contexts from active packet data protocol contexts, wherein the first set is for a transfer from cellular network device coverage to femto network device coverage, wherein the second set is for suspension during the transfer, wherein the selection comprises a ranking of the second set of active packet data protocol contexts based on respective monitored activity factors associated with applications associated with the active packet data protocol contexts , and wherein the ranking facilitates a resume sequence for the second set of active packet data protocol contexts in response to an active packet data protocol context for the transfer from the first set being determined to have been terminated; and

initiating, by the mobile device, a display of the selection.

2. The method of claim 1, further comprising conveying, by the mobile device, the indication to a component that manages packet data protocol contexts.

3. The method of claim 1, further comprising:

prompting, by the mobile device, for first user input confirming the selection.

4. The method of claim 3, further comprising, in response to receiving the first user input confirming the selection, resuming, by the mobile device, at least one of the active packet data protocol contexts of the second set according to the ranking in response to a packet data protocol context for the transfer being determined to have been terminated.

5. The method of claim 3, further comprising, in response to not receiving the first user input prompting, by the mobile device, for second user input specifying ranking of the active packet data protocol contexts of the second set.

6. The method of claim 1, wherein the selection comprises an additional ranking of the active packet data protocol contexts of the second set based on respective quality of service ranks associated with the active packet data protocol contexts of the second set, and wherein the additional ranking facilitates a resume sequence for the active packet data protocol contexts of the second set in response to the packet data protocol context associated with the transfer being determined to have been terminated.

7. The method of claim 1, wherein the ranking of the active packet data protocol contexts of the second set is further based on historical second user input received by the mobile device.

8. A non-transitory computer-readable medium with executable instructions stored thereon that, in response to execution, cause a device comprising a processor to perform operations, comprising:

receiving an indication of a selection of a first set and a second set of active packet data protocol contexts from a third set of active packet data protocol contexts, wherein the first set is for a transfer from cellular network coverage to femto network coverage and the second set is for suspension during the transfer, wherein the selection comprises a ranking of the second set of active packet data protocol contexts based on respective monitored activity factors associated with applications associated with the active packet data protocol contexts, and wherein the ranking facilitates a resume sequence for the second set of active packet data protocol contexts in response to an active packet data protocol context for the transfer from the first set being determined to have been released; and

displaying, by the mobile device, the selection.

9. The non-transitory computer-readable medium of claim 8, wherein the operations further comprise conveying the indication to a packet data protocol context management component.

10. The non-transitory computer-readable medium of claim 9, wherein the operations further comprise prompting for first user input confirming the selection.

11. The non-transitory computer-readable medium of claim 10, wherein the operations further comprise, in response to receiving the first user input confirming the selection, resuming at least one of the active packet data protocol contexts of the second set according to the ranking in response to a packet data protocol context for the transfer being determined to have been terminated.

12. The non-transitory computer-readable medium of claim 10, wherein the operations further comprise, in response to not receiving the first user input, prompting for second user input specifying a resume sequence for the active packet data protocol contexts of the second set.

13. The non-transitory computer-readable medium of claim 8, wherein the selection comprises an additional ranking of the active packet data protocol contexts of the second set based on respective quality of service ranks associated with the active packet data protocol contexts of the second set, and the additional ranking facilitates a resume sequence of the active packet data protocol contexts of the second set in response to the transfer packet data protocol context being determined to have been released.

14. The non-transitory computer-readable medium of claim 8, wherein the ranking of the second set of active packet data protocol contexts is further based upon historical second user input from a mobile device.

15. A wireless device, comprising:

a processor; and

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

receiving an indication of a selection of a first set and a second set of active packet data protocol contexts from active packet data protocol contexts, wherein the first set is for handover from cellular service coverage to femto service coverage and the second set is for suspension during the handover, wherein the selection comprises a ranking of the second set of active packet data protocol contexts based on respective monitored activity factors associated with applications associated with the active packet data protocol contexts, and wherein the ranking facilitates a resume sequence for the second set of active packet data protocol contexts in response to an active packet data protocol context for the transfer from the first set being determined to have ended;

presenting the selection.

16. The wireless device of claim 15, wherein the operations further comprise conveying the second user input to a packet data protocol context management computing system remote from the wireless device.

17. The wireless device of claim 15, wherein the operations further comprise prompting for first user input confirming the selection.

18. The wireless device of claim 17, wherein the operations further comprise, in response to receiving the first user input confirming the selection, resuming at least one of the active packet data protocol contexts of the second set according to the ranking in response to a packet data protocol context for the transfer being determined to have been terminated.

19. The wireless device of claim 17, wherein the operations further comprise, in response to not receiving the first user input, prompting for second user input specifying a resume sequence for the active packet data protocol contexts of the second set.

20. The wireless device of claim 15, wherein the selection comprises another ranking of the second set of active packet data protocol contexts based on respective quality of service ranks associated with the second set of active packet data protocol contexts, and the other ranking facilitates a resume sequence of the second set of active packet data protocol contexts in response to the packet data protocol context of the handover being determined to have ended.
