Communication method, communication system, and communication terminal

摘要

The invention relates to a one to multi communication method wherein each terminal participating in group communication can grasp the states of the other terminals, a communication system, and a communication terminal used for the same. Each terminal acquires information concerning its own state (for example the reception sensitivity of a signal from a base station) and transmits it via a communication management apparatus to the other communication terminals. Further, information concerning the states of the other communication terminals is displayed on a display part provided in each communication terminal. Due to this, each communication terminal can grasp correctly of the information concerning the states of the other communication terminals, therefore it becomes possible to judge whether or not the other communication terminals are in states where normal conversation is possible, and occurrence of a difference in recognition among users in the one to multi communication can be prevented.

主权项

1. A communication method of communication terminals used in a communication system performing group communication, said communication method characterized by having
a first step of transmitting, at one of the communication terminals engaged in group communication, first information concerning its own radio signal state, to each of the other communication terminals participating in the group communication, a second step of receiving, at one of the communication terminals engaged in group communication, first information indicating a radio signal state acquired at each of the other communication terminals participating in the group communication, and a third step of displaying, at one of the communication terminals engaged in group communication, both the received first information and the transmitted first information.
