ABSTRACT:
A system for mobile communication includes a number of base stations 10, 13, 16, 20, 23, 26 with users 30, 31, 45 and 46. Associated with each base station is an interface unit 10a, 13a, 16a, 20a, 23a and 26a 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 routing block 40 or 41 and switches 50-52. The stored information within the base station interfaces allows movement from one base station to allow to be handled without call loss.
