Abstract

The present invention provides a communication control system which can prevent unnecessary communication connections while ensuring user-friendliness when 1 to N communication is performed.

The communication control system judges whether an area code of a mobile terminal and area codes of the other mobile terminals of the group match, and establishes 1 to N communication between the mobile terminal and the mobile terminals of which area codes match. As a result, when the users are contacted to meet, for example, the communication control system can prevent unnecessary communication connections without indiscriminately connecting the mobile terminals of users at distant locations for whom it is difficult to travel for a meeting. In addition, the communication destination mobile terminals are automatically selected based on the area code, user-friendliness can therefore be sufficiently ensured.

Claims

1. A communication control system for controlling simultaneous communication among a plurality of mobile terminals belonging to a pre-registered group, comprising:

position information storage means for storing position information which indicates a current position of each of said mobile terminals;

start request information reception means for receiving start request information to request the start of a communication connection from one mobile terminal of said group;

area judgment means for judging whether other mobile terminals of said group are located within a predetermined area by referring to said position information stored in said position information storage means when said start request information reception means receives said start request information; and

connection control means for establishing a communication connection between said one mobile terminal and said other mobile terminals which have been judged as being located within said predetermined area by said area judgment means.

2. The communication control system according to claim 1, characterized in that said predetermined area is an area which is set with a current position of said one mobile terminal as a center.

3. The communication control system according to claim 1, characterized in that said predetermined area is an area which is set with a position specified by a user of said one mobile terminal as a center.

4. The communication control system according to claim 1, further comprising:

position information monitoring means for monitoring position information of each of said mobile terminals during communication and judging whether a current position of each of said mobile terminal mutually approaches within a predetermined distance; and

approach information transmission means for transmitting approach information to notify the mutual approach of the current position to said mobile terminal for which said position information monitoring means has judged that the current position has mutually approached within said predetermined distance.

5. The communication control system according to claim 1, further comprising:

transmission request information reception means for receiving transmission request information to request the transmission of position information of one mobile terminal during communication to other mobile terminals during communication, from said one mobile terminal; and

position information transmission means for transmitting the position information of said one mobile terminal to said other mobile terminals when said transmission request information reception means receives said transmission request information.

6. The communication control system according to claim 1, further comprising:

receive request information reception means for receiving receive request information to request the reception of position information of other mobile terminals during communication from one mobile terminal during communication; and

position information transmission means for transmitting the position information of said other terminals to said one mobile terminal when said receive request information reception means receives said receive request information.
