Management systems, communication systems, management method, and a program

PROBLEM TO BE SOLVED: To solve such a problem that when a method for distributing the call automatically to a terminal of longest latency is used, reconnection is not established only after distributing the call to each communication terminal that has requested start of communication previously, when reconnecting after communication between the communication terminals is disconnected.SOLUTION: The wait information management DB5012 of a management system 50 manages the connection type information for identifying the terminal 10 of a communication start request source, when communication between the terminal 10 of a communication start request source and a destination terminal 10 is disconnected. When a plurality of terminals 10 are requesting communication between the destination terminal 10, a session control section 58 selects a terminal 10 to be connected with the destination terminal 10 among the plurality of terminals 10, based on the connection type information managed in the wait information management DB5012.SELECTED DRAWING: Figure 6
