Abstract: A process of switching a provision source server of a service for a mobile object is performed at a timing suitable for a service being provided. A management system or a management apparatus evaluates a degree of influence of a server switching process of switching a provision source server of a service for a mobile object, which is exerted on the service. The management system or the management apparatus decides a timing to switch the provision source server on the basis of an evaluation result of the evaluating and gives an instruction to switch the provision source server at the timing decided by the decision.

Abstract: To provide a communication system capable of easily selecting group communication to participate in halfway. A communication system according to the present disclosure includes a communication terminal and a server that controls group communication among a plurality of communication terminals. The communication terminal includes: an acquisition unit that acquires information regarding group communication that has already been started among the plurality of communication terminals and is in a non-answered state due to no answer at the start; a selection unit that selects any one from one or more group communications that are candidates for participation based on the acquired information; and a transmission unit that transmits a participation request for the selected group communication to the server. The server includes a participation acceptance unit that accepts participation of the communication terminal in the selected group communication.
