METHOD FOR CONTROLLING SWITCH IN PERFORMING CONTINUOUS HAND-OFF BETWEEN EXCHANGES

摘要

PURPOSE: A method for controlling switch in performing continuous hand-off between exchanges is provided to achieve the hand-off execution of a high speed with reduced system loads by minimizing the hand-off execution path in the anchor exchange and simplifying the speech path removing procedure in the serving exchange. CONSTITUTION: In the personal communication service exchanges(20-22), a subscriber(b) between two mobile subscribers(a,b) under lines busy in the same mobile radio interface subsystem ASS_W using the time switch proceeds forward hand-off(b') along the (a) line to the domain that other personal communication service exchange(21) manages and processes call with the speech path by intra_junctor in the same radio wireless interface subsystem(ASS_W). Then, the subscriber(b) proceeds inter-exchange continuous hand-off(b'') along the (b) line to the service domain that the third personal communication service exchange(22) manages.
