Mobile radio communications system.

摘要

Transmission quality and throughput are improved when communication is carried out using fixed-length packets in wire circuits (106) between radio base stations (101) and a mobile switching centre (107) in mobile radio communications systems. To achieve this, low bit-rate digital information signals are converted to short packets by a plurality of information data assembly/disassembly circuits (103,113) provided in parallel. A plurality of these short packets are transmitted after being inserted into a long fixed-length packet by means of a fixed-length packet assembly/disassembly circuit (104,114) and a plurality of short packets are extracted from the fixed-length packet and then restored to the low bit-rate digital information signals by information data assembly/disassembly circuits. This enables high throughput, economical communication paths to be constructed. <IMAGE>
