SYSTEM FOR INTRA-STATION CHANNEL SWITCHING BETWEEN SYSTEMS IN THE SAME STATION IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE:To obtain a channel switching function across areas different in radio system in the same station by adopting a conventional inter-system and inter- station channel switching processing and starting this processing to actually realize the inter-system intra-station channel switching. CONSTITUTION:When a mobile terminal 2 is moved to another area E2 different in radio system in the same station in the case speech is carried out between a subscriber terminal 9 and the mobile terminal 2 in an area E1, the inter-system and inter-station channel switching processing is activated, and a channel switching trunk 7 is changed to temporarily send a signal sent to a station in use to a loop trunk 5-1 of its own station. The signal is fetched to its own station through a loop back trunk 5-2 to be a pair for this loop back trunk 5-1 and the inter-station interface processing is performed, and thereafter, the inter-system and inter-station channel switching processing is executed in a station 1. Then, the signal sent to its own station accesses the mobile terminal 2 in the area E2 through a bidirectional trunk 4-2 for the area E2 and a radio base station 3-2.
