Abstract
A system for mobile communication includes a number of base stations. Associated with each base station is an interface unit which packetises voice information and includes header information concerning user and destination addresses. These interface units tracks the movement of the various user by passing control blocks from interface unit to interface unit. Packets are routed via a routing block and switches. The stored information within the base station interfaces allows movement from one base station to allow to be handled without call loss.
