PACKET DATA PROTOCOL CONTEXT MANAGEMENT FOR HANDOVER FROM CELLULAR NETWORK TO A FEMTO CELL
First Claim
1. A method for managing packet data protocol (PDP) contexts during handover from cellular coverage to femto coverage, the method comprising:
- comparing activity of a set of PDP contexts;
ranking a subset of active PDP contexts in the set of PDP contexts based at least in part on a quality of service profile (QoS) for each active PDP context or subscriber input; and
handing over a group of PDP contexts within the subset of active PDP contexts with the highest rankings of QoS requirements or subscriber input, the number of PDP contexts in the group dictated by femto network capability.

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.

7. A computer-readable storage medium with instructions stored thereon that, when executed by a processor, cause a computer to perform the following acts:
-
comparing application activity for a set of PDP contexts and suspending a subset of PDP contexts that are inactive; ranking a subset of active PDP contexts in the set of PDP contexts based at least in part on one of a quality of service profile (QoS) for each active PDP context or a subscriber input; suspending a group of PDP contexts without the highest ranking of QoS requirements or subscriber input, the group of suspended PDP contexts complements the groups of handed over PDP contexts; and handing over a group of PDP contexts within the subset of active PDP contexts with the highest rankings of QoS requirements or subscriber input, the number of PDP contexts in the group dictated by femto network capability.

8. A system that facilitates management of packet data protocol (PDP) contexts upon cellular-to-femto handover, the system comprising:
-
a component that compares application activity of a set of PDP contexts; a ranking component that ranks a subset of application active PDP contexts in accordance at least in part with one of quality of service (QoS) requirements or subscriber input; a management component that hands over a group of PDP contexts within the subset of application active PDP contexts with the highest rankings of QoS requirements or subscriber input, the number of PDP contexts in the group dictated by femto network capability. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method for managing packet data protocol (PDP) contexts during handover from cellular coverage to femto coverage, the method comprising:
-
receiving an active PDP context through handover; and receiving a ranking of active PDP contexts suspended prior to handover, the ranking based at least in part on quality of service (QoS) requirements or subscriber input. - View Dependent Claims (18, 19, 20)

21. A computer-readable storage medium with instructions stored thereon that, when executed by a processor, cause a computer to perform the following acts:
-
receiving one or more active PDP contexts through cellular-to-femto handover, the number of received active PDP contexts determined through femto network capability; receiving a ranking of active PDP contexts suspended prior to handover, the ranking based at least in part on quality of service (QoS) requirements or subscriber input; initiating resume of highest ranking suspended PDP context when one or more of the handed over active PDP context is released; and requesting PDP context modification of the highest ranking suspended PDP context to be resumed and resuming the highest-ranking PDP context when PDP context modification is complete.

22. A system, comprising:
-
a packet data protocol (PDP) management component that receives a set of active PDP contexts through handover; and a component that receives a ranking of active PDP contexts suspended prior to handover, the ranking based at least in part on quality of service (QoS) requirements or subscriber input. - View Dependent Claims (23, 24, 25, 26)
