Abstract:
1. A wireless terminal device comprising: a communication switching unit that selectively switches between a first communication system and a second communication system, for performing communication; and a determination unit which, upon communication initiation being requested in a situation where a location registration is performed in the first communication system, determines whether or not the communication initiation is of a predetermined communication type of which positioning in the second communication system is requested after the communication initiation; wherein if it is determined by the determination unit that the communication initiation is not of the predetermined communication type, the communication switching unit changes a location registering destination by giving priority to the first communication system after communication based on the communication initiation is completed in the second communication system, and if it is determined that the communication initiation is of the predetermined communication type, the communication switching unit continues the location registration to the second communication system even after the communication based on the communication initiation is completed in the second communication system.
