Abstract
A method to enable mobility while connected to an Internet protocol network comprises receiving a first data packet from a mobile node at a first mobile gateway in a mobile-gateway-communication network via a first access point and determining if a communication session is ongoing responsive to receiving the first data packet. When it is determined that a communication session is not ongoing, the first mobile gateway is established as a home mobile gateway for the duration of the communication session. When the mobile node connects to a second mobile gateway in the mobile-gateway-communication network via a second access point during the communication session, a tunnel is opened from the second mobile gateway to the home mobile gateway so that the communication session is maintained regardless of the protocol implemented by the mobile node and the access points.
