Abstract
A method of maintaining connectivity and synchronization of data from a first application resident in a first mobile computer to a second application resident in a second computer wherein the data is transmitted over a data communications network including a plurality of stationary access points, determining, in said first mobile computer, that communications between the first mobile computer and the second computer has been impeded, and that association with a different access point or use of a different radio channel should be attempted in order to continue communications; storing and queuing the messages while a new link is established; and re-establishing a link between first and second virtual sockets in the respective computers in order to continue a session between the first and second applications in the first and second computer respectively.
