Packet data protocol context management for handover from cellular network to a femto cell

摘要

Packet data protocol (PDP) contexts are managed 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.

a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
comparing a set of activity levels corresponding to a set of active packet data protocol contexts and ranking a subset of the set of active packet data protocol contexts based on a function of input received via a mobile device user interface and a quality of service requirement of an application associated with the subset of the set of active packet data protocol contexts;facilitating a transfer, from cellular device coverage to femtocell network device coverage, of an active packet data protocol context of the subset of active packet data protocol contexts with a defined level of the quality of service requirement in response to receiving a selection of the active packet data protocol context;suspending another active packet data protocol context of the set of active packet data protocol contexts that was not transferred;signaling a cellular network device to modify a highest ranking suspended packet data protocol context in response to a release of the active packet data protocol context that was transferred; andresuming the highest ranking suspended packet data protocol context in response to a modification of the highest ranking suspended packed data protocol context.
