Abstract
In a network including a relay apparatus, a relay apparatus management part, a communication management server for controlling communication between communication terminals including a mobile communication terminal, and a messaging server, a communication support system that supports an establishment of connection between communication terminals includes a communication information acquiring part for, in a case where communication cannot be established between a mobile communication terminal and a partner-side terminal due to the congestion of communication, receiving terminal data thereof, a relay apparatus specifying part for specifying an alternative relay apparatus, and a message control part for causing a messaging server to perform processing of transmitting an inquiry message for inquiring about a possibility of movement to a coverage area of the alternative relay apparatus and processing of transmitting a content of a response message. The communication support system enables a rapid transition to a state in which communication between the mobile communication terminal and the partner-side terminal can be established, by allowing information to be exchanged between both the terminals, even in a case where the communication between the terminal and the relay apparatus is congested.
