Abstract: A broad aspect of the invention provides a method of providing mobility support for a mobile node's traffic. The method involves maintaining context information for the mobile node on each of a first plurality of network nodes carrying the traffic; and proactively transferring and maintaining at least a portion of the context information in a plurality of network nodes which are not carrying the traffic, but which are candidates for carrying the traffic due to mobility of the mobile node. The method typically further involves defining and maintaining a definition of the second plurality of network nodes. In one embodiment of the invention, this involves adding a particular network node to the second plurality when the particular network node becomes a candidate for carrying the traffic, removing a particular network node from the second plurality when the particular network node is no longer a candidate for carrying the traffic.

Abstract: An automatic cell transfer is made, when a mobile detects certain threshold exit bit or symbol error rate in a message transmitted from the base station with which it is communicating, by the mobile then sampling sequentially transmitted messages from adjacent base stations (on the same or different frequencies) and monitoring their bit or symbol error rates until a base station is found having a bit or symbol error rate less than a preselected minimum entry threshold bit or symbol error rate which in turn is less than the exit bit or symbol error rate and transferring communication from the mobile to the base station so selected. In one arrangement, each base station repeatedly and intermittently transmits a known quality assessment message and the mobile continually reviews the received message for its error rate.
