COMMUNICATION SYSTEM

A communication system includes: a plurality of mobile terminals; and a linked apparatus that works in concert with the plurality of mobile terminals. The linked apparatus is configured to establish a wireless connection to a selected one of the plurality of mobile terminals. The selected one of the plurality of mobile terminals is designated as a relaying apparatus that relays communications. The plurality of mobile terminals includes: a first mobile terminal that serves as the relaying apparatus before a change of selection of the relaying apparatus; and a second mobile terminal that serves as the relaying apparatus after the change of selection of the relaying apparatus. In a case where the selection of the relaying apparatus is changed from the first mobile terminal to the second mobile terminal, (1) the first mobile terminal sends, to the linked apparatus, a credential that is used to establish a wireless connection to the second mobile terminal, the credential being acquired from the second mobile terminal, and (2) the linked apparatus establishes the wireless connection to the second mobile terminal as the relaying apparatus using the credential.
