Abstract: PROBLEM TO BE SOLVED: To allow a mobile communication system to select a communication opposite party by designating a concrete position. SOLUTION: A server stores and manages position information (latitude and longitude) of each mobile station 22. When a mobile station 22 transmits a mail including designation of its own position range and information to be served to the server 12, the server 12 discriminates whether or not each mobile station 22 is resident within the range on the basis of respective position information of the mobile stations 22 and the range (longitude and latitude in the center of the mobile stations 22 and its radius) denoted in the mail to obtain user names (telephone numbers) of all the mobile stations 22 resident in this range. When many mobile stations 22 are resident within the range, the server 12 limits the number of the mobile stations 22 on the basis of attributes of the users or the like and transmits a mail including the served information to each of the mobile stations 22 obtained finally.

Abstract: PROBLEM TO BE SOLVED: To properly maintain the limitation of access to a file even after the file is transferred. SOLUTION: A system for setting the limitation of access to a file comprises a storage part for storing the hash value of second file and the limitation information indicating the limitation of access set before combined to the second file among at least one of the second files combined as a single first file in association with each other, a retrieval part for calculating the hash value of at least one of fourth files generated and retrieving the hash value corresponding to the calculated hash value from the storage part under the condition that the fourth files are generated by dividing a single third file, and a limitation set part for setting the limitation of access to the fourth file according to the limit information stored in the storage part in association with the retrieved hash value under the condition that the hash value corresponding to the hash value of the fourth file is retrieved.

Abstract: PROBLEM TO BE SOLVED: To realize an interactive communication in an on demand communication in heavy movement for a party consisting of uncertain terminals sharing subjects, a reduction of traffic in a network in the same group so as to reduce power consumption of communication terminals. SOLUTION: In the communication terminals 101-116 realizing group communication of radio ad hoc network of which the connection is rearranged by movement of the terminals 101-106 with high frequency in comparison to that of communication packet, an identification information and an expiry data information of an adjacent terminal together with an expiry date of own station in which the date itself belongs to the group are stored into a group managing table 11, and a transmitting receiving device 20 adds an identification information of itself, also adds the date information of the group based on the expiry date information stored in the table 11 so as to make packet transmission.

Abstract: PROBLEM TO BE SOLVED: To enable a mobile communication system to select a communication party by designating a definite position. SOLUTION: A server 12 stores and manages the positional information (latitudes and longitudes) of mobile stations 22. When the mobile stations 22 transmit mail including information designating and providing the positional extents of their communicating parties to the server 12, the server 12 discriminates whether or not the mobile stations 22 are in the extents (center latitudes, longitudes, and radii) contained in the mail based on the positional information of the stations 22 and the extents, and obtains the names (telephone numbers) of the users of all mobile stations 22 existing in the extents. When the number of the mobile stations 22 existing in the extents is large, the server 12 reduces the number of the mobile stations 22 based on the attributes, etc., of the users and transmit the mail containing information to be provided to each finally obtained mobile station 22.

Abstract: PROBLEM TO BE SOLVED: To enhance message transmission efficiency by effectively reducing the communication quantity of multiple address relay transfer by means of simple decision logic. SOLUTION: When a sender terminal T0 transmits a message to a transmission source terminal T1 via an optional terminal and the transmission source terminal T1 transmits the message to a mobile terminal T2, the terminal T2 calculates an information traveling vector I denoting the information traveling direction and a terminal traveling vector M denoting the direction of its own traveling, obtains a normalized inner product cosθ between the information traveling vector I and the terminal traveling vector M and has a logic of transferring the received message when a condition of cosθ>=0 is satisfied.
