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.

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 control propagation of information in a more proper form by measuring the prescribed characteristic of a received radio signal and deciding the response timing of the received radio signal, based on the measured characteristic and a response policy corresponding to the measured characteristics. SOLUTION: An electric field strength measurement device 5 measures the electric field strength of a radio electric signal outputted from a transmitter-receiver 3 which receives a radio signal received by an antenna 1, and gives the result to a communication controller 7. Upon the receipt of a connection request, the communication controller 7 decides when a reply is to be returned in response to the connection request and instructs the transmitter-receiver 3 to start communication in a proper timing. The transmitter-receiver 3 gives the connection request, including a terminal ID and a response policy for start of communication, to the controller 7 to await a connection reply from other radio transmitter-receiver. The waiting state transits to a call- receiving state, when receiving the connection request from other radio transmitter- receiver. In the call-receiving state, the communication controller 7 returns a connection response to decide whether or not communication is executed or when a response timing is returned, when replying the connection response.

Abstract: PROBLEM TO BE SOLVED: To transmit more local information to a user existing in a prescribed range by calculating a distance from an information source through the use of position information, comparing it with a prescribed threshold and deciding received information so that it cannot be transferred at the time of deciding the propriety of the transfer of received information containing position information of the information source. SOLUTION: A communication controller decides the propriety of information transfer. Whether information which is decided so that it is to be transferred at first is judged to be valid or not (210). When it is overdue, information is not transferred (270). Then, it is judged whether it itself is detached from an information source by a prescribed distance or not (220). It can be judged according to whether a self-position detected from a position detector is within a circle whose radius is set to be a distance as a threshold with the information source as a center from the distance inputted to the frame of transfer information as the threshold and the position of the information source in the frame. When it is detached from the information source for more than the prescribed distance, information is not transferred (270).

Abstract: According to the present invention, a wireless transceiver on a reception side performs the steps of: measuring a radio strength of a radio signal received from another wireless transceiver; and by using the measured radio strength and a response policy concerning radio strength, determining the response timing to the received radio signal. A wireless transceiver on a transmission side performs the steps of: specifying a response policy concerning a radio strength for other wireless transceivers that will receive a radio signal; and transmitting to the wireless transceiver a radio signal including the specified response policy. As a result, a wireless transceiver located in an area where the wireless transceiver on the transmission side can be connected can be specified.
