Abstract:
Apparatus and methods are described herein for managing data network connections. When a gateway or user equipment receives a message indicating the active data network connections associated with the sending party, the gateway or user equipment checks a locally stored list of active data network connections to determine whether there is a match. If at least one active data network connection does not match, the receiving device sends a message to the sending party indicating the locally stored active data network connections.
