PROBLEM TO BE SOLVED: To continue message exchange without being affected of a state of near distance wireless communication even when the near distance wireless communication is interrupted. SOLUTION: Mobile wireless terminals 10A-1, 10A-2 are both configured as shown in Figure 2 and execute a message exchange protocol employing near distance wireless communication. In this case, when a near distance wireless communication detection section 18 of the mobile wireless terminal 10A-1 detects interruption of the message exchange protocol, the mobile wireless terminal 10A-1 acts like a requester, executes a control protocol to switch a message exchange protocol execution function by using a wireless phone communication function with respect to the opposed mobile wireless terminal 10A-2, and the message exchange protocol between the mobile wireless terminal 10A-1 and the mobile wireless terminal 10A-2 is switched into a message exchange protocol using the wireless phone communication under the control of wireless phone communication connection management sections 16 of the both.
