A network-based mobile workgroup system has considerably wider appeal and application than normal virtual private networks in that it provides seamless mobility across a number of access technologies at the same time as it offers a granular security separation down to workgroup level. The mobile workgroup system is an access management system for mobile users with VPN and firewall functionality inbuilt. The mobile user can access the mobile workgroup system over a set of access technologies and select server resources and correspondent nodes to access pending their workgroup membership approvals. All workgroup policy rules are defined in a mobile service manager and pushed down to one or more mobile service routers for policy enforcement. The mobile service router closest to the mobile client, and being part of the mobile virtual private network, performs regular authentication checks of the mobile client during service execution. At the same time it performs traffic filtering based on the mobile user's workgroup memberships. Together, these two components constitute an unprecedented security lock, effectively isolating a distributed workgroup into a mobile virtual private network.

A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. A Mobility Management Server coupled to the mobile network maintains the state of each of any number of Mobile End Systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task—allowing the Mobile End System to maintain a continuous connection even though it may temporarily lose contact with its network medium. An interface-based listener uses network point of attachment information supplied by a network interface to determine roaming conditions and to efficiently reestablish connection upon roaming. The Mobility Management Server can distribute lists to Mobile End Systems specifying how to contact it over disjoint networks.
