Abstract:
1. An integrated chassis residing in a communication network comprising: a processor; a memory for storing instructions and in operable communication with the processor; a plurality of session managers implemented in a computer-readable medium, the plurality of session managers in operative communication with and sharing the processor, the plurality of session managers for receiving control information and data from a mobile node in a first access technology and for setting up a session for the mobile node with the first access technology, each of the plurality of session managers configured for communicating with a first access technology stack and at least a second access technology stack to manage packet processing for either of the first or at least a second access technology to enable communication with the mobile node, wherein the second access technology stack implements an access service network gateway (ASNGW); and an access technology demux manager implemented in the computer-readable medium in operative communication with the processor for selecting for the session an assigned session manager from among the plurality of session managers for communicating with the mobile node with the first access technology, the access technology demux manager, in response to a handoff to a second access technology, for selecting the same assigned session manager from among the plurality of session managers where an existing session is set up in the first access technology such that the mobile node changes to a second access technology and retains the same assigned session manager.
