Method and apparatus for providing mobile and other intermittent connectivity in a computing environment
First Claim
1. In a mobility communications system including at least one mobile device that substantially seamlessly roams between plural IP-based point-of-presence networks, further characterized by:
- said mobile device communicating over a local mobile network with at least one further node; and
said mobile device enables application data communicated to/from said at least one node to communicate with an ultimate peer(s) that may or may not be attached to the local mobile network.

Abstract
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.

- 28. A mobility management system characterized by an automatic load balancing method and sharing method including hierarchical clustering of mobility management systems into server pools for adding capacity on-the-fly without disruption to connected systems and/or users, further characterized in that said server pools are divided into zones.

33. A Mobile Proxy Communications Service comprising:
-
at least one communications arrangement that communicates with at least one node via said locally coupled mobile network, and also communicates with a mobile end system via at least one IP-based Point-of-Presence network, wherein said node is not mobile aware; and
a processing arrangement that allows for application data communicated to/from said at least one node to communicate with an ultimate peer(s) that may or may not be attached to the mobile private network.
