Information processing apparatus, communication platform determining method, transmission system, and transmission terminal

A communication platform switching method that is implemented by a transmission terminal that communicates with an information processing apparatus including

• a state detection unit configured to detect a communication state relating to at least one of a communication between at least two of the transmission terminals communicating with each other and a communication between at least one of the transmission terminals and the information processing apparatus;
• a read unit configured to read from a storage unit communication platform determination information that associates the plurality of communication platforms with the communication state;
• and
• a determination unit configured to determine that a communication platform of the plurality of communication platforms that is registered in the communication platform determination information in association with the communication state that has been detected by the state detection unit is to be used in the communication between the transmission terminals communicating with each other;
• wherein the state detection unit acquires a plurality of communication platform switch requests from a plurality of the transmission terminals;
• and
• wherein the determination unit includes a supplemental determination unit that decides to switch to a majority communication platform that is designated in at least a majority number of the communication platform switch requests that has been acquired from the plurality of the transmission terminals, the majority number exceeding half of a total number of the transmission terminals that are communicating with each other;
• the communication platform switching method including a step of establishing communication using a communication method corresponding to a designated communication platform designated in a communication platform switch command upon acquiring the communication platform switch command from the determination unit.
