MOBILE COMMUNICATION SYSTEM USING PORTABLE MOBILE TERMINAL EQUIPMENT

PURPOSE:To make the line utilization efficient by eliminating a holding line during calling. CONSTITUTION:Upon the receipt of a call from a public terminal equipment, a relay control station 3 makes paging from a pager base station 6 to a called party 1 and interrupts once a line from the relay control station 3 to a caller 4 and a line till the pager base station 6 entirely. After the presence of a reply to the paging, the line from the relay control station 3 till the caller and a lien up to the radio base station setting a communication channel with a portable mobile terminal equipment 1 are connected. Thus, the line is not occupied as a holding line till the call of the caller 4. Furthermore, the system is easily realized by the use of an existing pager system and an existing public telephone network and simultaneous calling is applied to the caller independently of a minimized zone.
