Abstract

Systems and method are for managing packet data protocol (PDP) contexts in a wireless data communications network. A plurality of real-time applications are prioritized within a single, shared PDP context or allocated a second PDP context based upon priority levels logically assigned to the plurality of applications such that high priority applications are delivered before lower priority applications. Lower priority applications are suspended and interrupted by higher priority applications and are set to resume after the higher priority applications are completed. Priority levels are established by a priority management engine (PME) that may reside in one or more network elements, such as a General Packet Radio Service (GPRS) Support Node or a network probe system. The priority management engine establishes the priority levels based upon one or more factors including, for example, PDP utilization characteristics at a given time and / or given network location, and / or user preferences.

Description

[0001] Cross references to related patent applications [0002] This patent application claims priority to US Patent Application No. 12 / 707,791, filed February 18, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to data communication networks, and more particularly to systems and methods for managing Packet Data Protocol (PDP) contexts in wireless data communication networks. Background technique [0004] A PDP context provides a packet data connection over which a mobile device and a data network can exchange Internet Protocol (IP) packets. The PDP context has a record of parameters consisting of all the messages required to establish an end-to-end connection using the data network. These parameters include PDP type, PDP address type, Quality of Service (QoS) profile request (e.g., QoS parameters requested by the user), QoS profile negotiated by the data network, authentication type, and Doma...
