Mobile radio communications system

摘要

Transmission quality and throughput are improved when communication is carried out using fixed-length packets in wire circuits between radio base stations and a mobile switching center in mobile radio communications systems. Low bit-rate digital information signals are converted to short packets by a plurality of information data assembly/disassembly circuits 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, 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.
