Closed group communication method and communication terminal equipment
First Claim
1. A group communication method in which a plurality of communication terminals form a closed communication network and perform communication, said group communication method comprising a step in which a calling message including group identification information is broadcast from a first communication terminal to a large number of unspecified communication terminals, and a step in which the first communication terminal receives response messages broadcast from other communication terminals and including the group identification information, wherein the closed communication network is formed of the first communication terminal and at least one communication terminal which transmits the response message within a given time after the calling message is transmitted, and a group communication is performed by the communication message using the group identification information.

Abstract
In a group communication method which autonomously builds up a closed communication network using a large number of unspecified communication terminals, a calling message including group identification information is broadcast to a large number of unspecified communication terminals from an arbitrary communication terminal, a response message including the group identification information is broadcast from other communication terminal, and a closed communication network is formed of the communication terminal and at least one communication terminal which transmits the response message within a given time whereby a group communication is performed by the communication message using the group identification information.

a step in which a calling message including group identification information is broadcast from a first communication terminal to a large number of unspecified communication terminals, and a step in which the first communication terminal receives response messages broadcast from other communication terminals and including the group identification information, wherein the closed communication network is formed of the first communication terminal and at least one communication terminal which transmits the response message within a given time after the calling message is transmitted, and a group communication is performed by the communication message using the group identification information.
- 6. A group communication method which performs communication by forming a closed communication network with a plurality of communication terminals, the group communication method comprising a step in which a calling message for forming the group broadcast from other communication terminals is received, a step in which a communication terminal which has a will to participate in the group broadcasts a response message including group identification information which the calling message indicates, and a step in which the calling message received from other communication terminal and a terminal address which indicates a transmission source of the response message are stored as an address of a group constituting terminal corresponding to the group identifier, wherein a closed communication network is formed of the communication terminal which becomes the transmission source of the calling message and at least one communication terminal which transmits the response message within a given time after the transmission of the calling message, and group communication is performed by the communication message using the group identification information.

10. A communication terminal equipment which performs a group communication with other communication terminals comprising
a transmission/reception circuit for transmitting and receiving a communication message, a display device, an input device manipulated by a user, a storage part which stores a connection control program for controlling a transmission/reception of the communication message, and a processor which executes the connection control program, wherein the processor broadcasts the calling message including group identification information to a large number of unspecified communication terminals in response to an user input from the input device, stores an address of the transmission terminals of the response message including the identification information received by the transmission/reception circuit, forms a group between the communication terminal equipment and the transmission terminal of the response message received within a given time after transmitting the calling message, and performs a control operation such that the group communication is performed using the group identification information.
