Abstract
Systems and methods are provided for maintaining communications with mobile users within organizational logical network groups when transitioning between logical groups. A client mobility agent resides as part of a mobile communication unit and monitors link metrics to determine if a transition to another logical network group is desired. The client mobility agents and a server mobility agent collaborate to reassign or re-home a mobile communication unit to a new home logical network group, and provide the mobile communication unit with a new group address upon entering a new logical network. The server mobility agent collaborates with a server mobility agent of the previous logical group that the mobile communication unit was a member to transfer sessions and services associated with the mobile communication unit to the new logical network.
