FIG. 5 is a flowchart for explaining the operation of this embodiment.

B-1. First, the PHS terminal 6 refers to a telephone book registered in advance in the RAM 18 in step S10 shown in FIG. When the destination is selected, next, in step S12, a call request is transmitted to the nearby (in the area) radio base station 5 using the destination telephone number of the selected destination. Next, in step S14, it is determined whether or not there is a response from the transmission destination via the radio base station 5, that is, whether or not the line is connected.

  When the call request is sent, the radio base station 5 sends a connection request to the network management station 1 using the call destination telephone number in step S30. Next, in step S32, it is determined whether or not there is a response from the call destination. If there is no response from the destination, that is, if the line is not connected, the determination result in step S32 is “NO”, and the flow proceeds to step S34. In step S34, a disconnection notification is transmitted to the originating PHS terminal.

  When the disconnection notification is transmitted, the determination result in step S14 is “NO” in the PHS terminal, and the process proceeds to step S16. In step S <b> 16, based on the time by the time measuring unit 20, the date of transmission is stored as the start date, the time of transmission is stored as the start time, and the destination telephone number is stored in the redial list of the RAM 18. Then, the process ends. In this case, since the line is not connected, the end date and end time are not stored in the redial list.

  On the other hand, when there is a response from the destination in the radio base station 5, that is, when a line is connected, the determination result in step S32 is “YES”, and the process proceeds to step S36. In step S36, together with the connection notification, the base station location name (for example, the Shinjuku Station West Exit) stored in the memory 5a of the destination radio base station 5 is read out and transmitted to the source PHS terminal 6.

  On the other hand, in the PHS terminal 6, when the connection notification is transmitted, the determination result in step S14 is “YES”, and the process proceeds to step S18. In step S18, based on the time by the time measuring unit 20, the start date, start time, destination telephone number, base station location name supplied from the wireless base station 5, and line type (public / home) Is stored in the redial list of the RAM 18.

  Next, in the PHS terminal 6, in step S20, the radio base station 5 performs a call with the destination party in step S38. When the call ends, the PHS terminal 6 transmits a call end notification to the radio base station 5 in step S22. In step S40, the source radio base station 5 that has received the end-of-call notification disconnects the line (call disconnection) and ends the process. On the other hand, in the PHS terminal 6, when the end-of-call notification is transmitted in step S 22, the process proceeds to step S 24, and the end date and time when the line is disconnected are stored in the redial list of the RAM 18 based on the time by the time measuring unit 20. To do. Then, the process ends.

Note that the call processing at the call destination will be briefly described because the same processing as the call processing at the call source described above is performed. In the destination PHS terminal 6, when a connection request is received from a nearby (in the area) wireless base station 5, a ring tone is sounded to notify the user. When the user presses the call button 32, the line is connected. At this time, the destination radio base station 5 reads the base station location name (for example, the Tokyo Station South Exit) stored in the memory 5a of the source radio base station 5, and sends it to the destination PHS terminal 6. Send. In the destination PHS terminal 6, similarly to the source PHS terminal, from the start date, start time, source telephone number, source radio base station 5 to which the line is connected, based on the time by the timer 20. The supplied base station location name and line type (public / home) are stored in the recall list of the RAM 18. When the call ends, the end date and time when the line is disconnected are stored in the recall list of the RAM 18 based on the time by the time measuring unit 20. Then, the process ends.

B-3. Display Example during Redial Next, a display example of the display unit 19 during redial will be described. Here, FIGS. 6A and 6B are schematic views showing a display example of the display unit 19 in the redial process.
