<p>Information transmission requests are delivered to the communication terminals existing in a particular area to collect information held in the communication terminals without causing congestions. An information collecting apparatus (100) included in an information collecting system (2) acquires, based on base station identifying information, both terminal information and capacity information and further acquires, based on the type of collected information, information of information amount of collected information. Further, an information collection control unit (102) generates, based on the terminal information, information of information amount and capacity information, transmission timing information in which a timing is so designated as not to exceed a capacity within which to perform communication via a base station. An information transmission request including the transmission timing information is delivered to a communication terminal (60). A timing at which each of a plurality of communication terminals existing in a cell under the control of a base station responds to an information transmission request is designated, thereby preventing the plurality of terminals under control from simultaneously sending their respective replies, thereby suppressing congestions from occurring due to increase of communication amount.</p> |
