Communication terminals forming a group are capable of performing push-to-talk group communication through the server apparatus. In reception of a call setting request from a first communication terminal of the group by the receiver, when the group includes a second communication terminal to which call setting fails, the transmitter transmits, to a communication terminal of the group, an instruction to execute a discovery processing of discovering a communication partner terminal capable of performing a direct communication with the communication terminal without passing through the server apparatus. When a result of the discovery processing reveals that a third communication terminal that has received the instruction from the server apparatus is capable of performing the direct communication with the second communication terminal, call setting between the server apparatus and the second communication terminal is performed through the third communication terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Server apparatus, communication apparatus, and communication method","description":"A server apparatus, a communication apparatus, and a communication method are disclosed.
