RADIO SYSTEM WITH TERMINAL IDENTIFICATION FUNCTION

PROBLEM TO BE SOLVED: To avoid assignment of the same UATI to a plurality of terminals by effectively using a UATI even when resource capacity for managing call information is small in a 1x EVDO system. SOLUTION: In a call information management part, Chagebits are provided for each record of a call information management table, frequencies of assignation of the same UATI are reduced by adding values which are added to each other whenever records of the same call information management table are used to the UATI and assignment of the same UATI to the plurality of terminals is avoided.
