ができる。In a conventional PHS terminal capable of using both a public protocol and a privately-used protocol, a switching method is adopted in which one of the protocols is preferentially used. That is, when the PHS terminal is set to preferentially use the self-employed mode, in an area where only the self-employed mode can be received, location registration is performed in the self-employed mode to wait for an incoming call in the self-employed mode, and only the public mode can be received. In the public mode, the location registration is performed and the incoming call is waited in the public mode. In the area where both the private mode and the public mode can receive, the location registration is performed in the private mode and the incoming call is waited in the private mode. In addition, the PHS terminal can automatically select the mode.

Switch to and search for your own LCCH. When the private LCCH cannot be received, the protocol switching control unit 13 switches to the public protocol control unit 12 to search for the public LCCH, as shown in FIG. If the public LCCH can be received, the public standby timer is set to t 4 [seconds]. It is determined whether or not the location registration has already been performed on the public PHS network, and if not, the location registration procedure is performed on the public PHS network. Next, it waits for 4 seconds in public mode and waits for an incoming call in public mode. If the public mode cannot be received during this standby period or if the public standby time t 4 seconds has elapsed, the protocol switching control unit 13 switches to the private protocol control unit 11 to search for a private LCCH. If the private LCCH cannot be received, the public protocol control unit 12 is switched to search for the public LCCH. When the public LCCH can be received, the public standby timer 15 is started and the above operation is repeated.

It is also the setting value of the public standby timer 15 when the public LCCH can be received. When only the public LCCH can be received, it is not always necessary to search the private LCCH. However, since it is possible that the user moves into an area where the self-employed mode can be used, the self-employed LCCH is searched at a cycle longer than the self-employed LCCH search cycle when the self-employed mode and the public mode can be received at the same time. Also, self-employed L
By increasing the CCH search cycle, it is possible to reduce the power consumption of the PHS terminal device.

ることができる。As described above, the portable telephone terminal device of the present invention can receive an incoming call in either mode in an area where the private mode and the public mode can be used. In this way, it is possible to reduce the number of incomplete calls caused by the fact that the PHS terminal according to the related art cannot respond. This also saves the caller from having to call back with the dial-in number.
Furthermore, for modes that do not exist in the area, power consumption of the device can be suppressed by lengthening the mode search cycle.
