Abstract
An example method includes receiving a packet for a flow associated with a subscriber; determining if a home agent element has a context for the flow by communicating a handover query to a network element; assigning an Internet protocol (IP) address for the subscriber in response to the home agent element not having the context for the flow; and creating a session for the subscriber, where the session is created using inter-process communication between the home agent element and the network element. The method can further include maintaining communications with a packet data serving node (PDSN) and an Authentication, Authorization, and Accounting (AAA) element in order to assist in roaming between a Long Term Evolution (LTE) network and a code division multiple access (CDMA) network. The inter-process communication is used to maintain the session for the subscriber when the subscriber is attached to different networks.
