<P>PROBLEM TO BE SOLVED: To provide a trigger generator for outputting trigger signals by relating the transmission/reception of the specified message of communication with a base station by a predetermined communication system and a timing synchronized with a specified system timing, for measurement of radio signals outputted from a radio interface part of a communication terminal. <P>SOLUTION: A message included in a communication sequence exchanged between the communication terminals is analyzed, the message satisfying a message condition for outputting a trigger is detected, system timing satisfying the timing condition for outputting the trigger is selected on the basis of the timing established for the communication with the communication terminal, and the trigger signal is outputted at the timing synchronized with the system timing corresponding to the timing condition after detecting the message satisfying the message condition. <P>COPYRIGHT: (C)2009,JPO&INPIT |
