In FIG. 7, the user performs an operation of switching the operation mode of the mobile phone 10S from the main line mode to the sub line mode (S1). As a result, the wireless communication unit 122 and the main control unit 120 of the mobile phone 10S transmit a De-REGISTER signal, which is an IMS service deregistration request, to the application server 240 (S2-1). However, it is assumed that this signal does not reach the application server 240 for some reason. In the mobile phone 10S, a timer is started in accordance with the transmission timing of the De-REGISTER signal, and time measurement is started. The timer expires at a predetermined time (for example, 1 minute), but a 200 OK signal that is a deregistration completion response indicating that the request for the De-REGISTER signal has been successfully received from the application server 240 can be received before the time expires. If not, the De-REGISTER signal is retransmitted in accordance with the time-up timing (S2-2). This procedure is repeated twice more, for example (S2-3, S2-4). If the 200 OK signal is not received even if the De-REGISTER signal is transmitted four times, the main control unit 120 of the mobile phone 10S forcibly completes the switching process from the main line mode to the sub line mode. (S3). A timer is activated in accordance with the timing of the switching process, and a De-REGISTER signal is transmitted to the application server 240 again in accordance with the timing up after a lapse of a predetermined time (for example, after 5 minutes) (S4). It is assumed that this signal reaches the application server 240. Upon receiving this signal, the application server 240 logs off the IMS service (S5), and transmits 200 OK, which is a deregistration completion response indicating that the request acceptance for the De-REGISTER signal has been successful, to the mobile phone 10S side (S6). . The 200OK is received by the wireless communication unit 122 of the mobile phone 10S and sent to the main control unit 120. Note that the timer is started in accordance with the transmission timing of the De-REGISTER signal and measures a predetermined time (for example, 5 minutes), but stops when the 200 OK signal is received. Although not shown in the drawing, the fact that all the operation mode switching processing has been completed and the sub-line mode has been entered is displayed on the display unit 125 as necessary, so that the user can confirm.

FIG. 8 shows an example of a communication procedure in the case where the REGISTER signal cannot be received by the application server 240 when the user switches the operation mode of the mobile phone 10S from the sub line mode to the main line mode, and the signal is retransmitted. It is a sequence diagram.
In FIG. 8, the user performs an operation of switching the operation mode of the mobile phone 10S from the sub line mode to the main line mode (S1). As a result, the wireless communication unit 122 and the main control unit 120 of the mobile phone 10S transmit a REGISTER signal, which is an IMS service registration request, to the application server 240 (S2-1). However, it is assumed that this signal does not reach the application server 240 for some reason. In the mobile phone 10S, a timer is started in accordance with the transmission timing of the REGISTER signal and time measurement is started. When the timer expires at a predetermined time (for example, 1 minute), but the 200 OK signal that is a registration completion response indicating that the request acceptance for the REGISTER signal has been successfully received from the application server 240 has not been received before the time is expired. Then, the REGISTER signal is retransmitted in accordance with the timing of time-up (S2-2). This procedure is repeated twice more, for example (S2-3, S2-4). If the 200 OK signal is not received even if the REGISTER signal is transmitted four times, the main control unit 120 of the mobile phone 10S forcibly completes the switching process from the main line mode to the sub line mode (S3). ). A timer is started in accordance with the timing of the switching process, and a REGISTER signal is transmitted to the application server 240 again in accordance with the timing up after a predetermined time has elapsed (for example, after 5 minutes) (S4). It is assumed that this signal reaches the application server 240. Upon receiving this signal, the application server 240 logs on the IMS service (S5), and transmits 200 OK, which is a registration completion response indicating that the request acceptance for the REGISTER signal has been successful, to the mobile phone 10S side (S6). The 200OK is received by the wireless communication unit 122 of the mobile phone 10S and sent to the main control unit 120. Note that a timer is started in synchronization with the transmission timing of the REGISTER signal and a predetermined time (for example, 5 minutes) is measured, but the timer is stopped upon reception of the 200 OK signal. Although not shown in the drawing, the fact that all the operation mode switching processes have been completed and the main line mode has been entered is displayed on the display unit 125 so that the user can confirm.

  Further, in the present embodiment, the reason why the De-REGISTER signal or REGISTER signal does not reach the application server 240 is that the mobile phone 10S exists outside the coverage area where the radio waves of the base station do not reach. In this case, since it is useless to transmit the De-REGISTER signal or REGISTER signal, the signal may be transmitted after transitioning to the area.

FIG. 9 is a flowchart showing an example of a procedure for switching the operation mode when the mobile phone 10S is outside the service area.
In FIG. 9, the user performs an operation for switching the operation mode of the mobile phone 10S from the main line mode to the sub line mode or an operation for switching from the main line mode to the sub line mode (S1). When this user operation is performed, the wireless communication unit 122 and the main control unit 120 of the mobile phone 10S check whether or not the mobile phone 10S is within a range where radio waves of the base station can reach (S2). If it exists in the vicinity, a De-REGISTER signal that is a request for deregistration of an IMS service or a REGISTER signal that is a registration request is transmitted to the application server 240 (S3). Then, 200 OK, which is a registration cancellation completion response or a registration completion response, is received (S4), and the switching process from the main line mode to the sub line mode or the switching process from the sub line mode to the main line mode is completed (S5). ), The fact that the switching of the operation mode has been completed is displayed on the display unit 125 (S6), and the process ends.

  On the other hand, when it is determined whether or not the mobile phone 10S is within the service area (S2), if it is not within the service area, that is, if it is out of service area, “out of service error” is displayed on the display unit 125 (S7). Then, the counter counts the number of times “out-of-service error” is displayed (S8). If the value of the counter is not a predetermined value (for example, 5 times) set in advance, a timer is started and a predetermined time (for example, 5 minutes) is measured (S9). After the time is up, it is checked again whether it is within range (S2). At this time, if it does not exist within the range, the above procedure (S7, S8, S9) is repeated. When the “out of service error” is displayed for the predetermined number of times, the counter counts up (S 8), and the display unit 125 displays that “switching operation is required again after the service area transition” (S 10). End. The counter is reset to zero when this is completed and when the operation mode switching is completed.
