PORTABLE TELEPHONE SYSTEM
Document Type and Number:
WIPO Patent Application WO/1997/049232
Kind Code:
A1
Abstract:
An exchange (3) has a call charging control section (6) which monitors the numbers of calls of transmission-only portable telephone sets (1B) for every terminal identification number whenever a telephone set (1B) makes a call, and rejects a call from the telephone set (1B) corresponding to the terminal identification number when the number of calls of a terminal identification number reaches a prescribed value, as a transmission-only portable telephone set management function in addition to the charging function. If the system operator inputs a permit from a prescribed operating terminal (7), etc., the section (6) again accepts a call from the telephone set (1B) corresponding to the terminal identification number from which the call has been rejected once.
