In the following description, the operation of each unit involved in a call is the same as the operation of a normal PHS terminal, and a description thereof will be omitted. FIG. 5 is a flowchart for explaining the operation of this embodiment.

B-1. Calling-Side Call Processing First, in step S10 shown in FIG. 5, the PHS terminal 6 refers to a telephone directory registered in the RAM 18 in advance and selects a call destination to which a call is to be made. When the call destination is selected, next, in step S12, a call request is transmitted to the nearby (within the area) wireless base station 5 using the call destination telephone number of the selected call destination. Next, in step S14, it is determined whether or not there is a response from the destination via the wireless base station 5, that is, whether or not the line is connected.

  When the call request is sent, the wireless base station 5 sends a connection request to the network management station 1 with the destination telephone number in step S30. Next, in step S32, it is determined whether or not there is a response from the transmission destination. Then, when there is no response from the transmission destination, that is, when the line is not connected, the determination result in step S32 is “NO”, and the process proceeds to step S34. In step S34, a non-connection notification is transmitted to the source PHS terminal.

  When the non-connection notification is transmitted, the PHS terminal determines “NO” in step S14, and proceeds to step S16. In step S16, based on the time by the timer 20, the originating date, the originating time, and the destination telephone number are stored in the redial list of the RAM 18 based on the originating date. Then, the process ends. In this case, since the line was not connected, the end date and end time are not stored in the redial list.

  On the other hand, if there is a response from the call destination in the wireless base station 5, that is, if the 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, Shinjuku Station West Exit) stored in the memory 5a of the destination wireless base station 5 is read 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 timer 20, the start date and time when the line was connected, the start time, the destination telephone number, the base station location name supplied from the wireless base station 5, and the line type (public / home) Is stored in the redial list of the RAM 18.

  Next, in the PHS terminal 6, in step S20, in the wireless base station 5, in step S38, a call is made with the call destination. Then, when the call ends, the PHS terminal 6 transmits a call termination notification to the wireless base station 5 in step S22. In step S40, the wireless base station 5 that has received the end-of-call notification disconnects the line (disconnects the call) in step S40, and ends the process. On the other hand, when the PHS terminal 6 transmits the end-of-call notification in step S22, the process proceeds to step S24, and based on the time by the timer 20, the end date and the end time of the line disconnection are stored in the redial list of the RAM 18. I do. Then, the process ends.

B-2. Next, a description will be given of a call process in the PHS terminal 6 and the wireless base station 5 of the destination (called side). Note that the call processing at the call destination will be described in brief because it is substantially the same as the above-described call processing at the call source. When the PHS terminal 6 of the transmission destination receives a connection request from the wireless base station 5 in the vicinity (within the area), the PHS terminal 6 sounds a ringtone to notify the user. Then, when the user presses the call button 32, the line is connected. At this time, the destination wireless base station 5 reads the base station location name (for example, Tokyo Station South Exit) stored in the memory 5a of the source wireless base station 5 and sends it to the destination PHS terminal 6. Send. In the PHS terminal 6 of the transmission destination, similarly to the PHS terminal of the transmission source, based on the time by the timer unit 20, the start date, the start time, the transmission source telephone number, and the transmission source radio base station 5 from the line are connected. 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 the end time of the line disconnection are stored in the recall list of the RAM 18 based on the time of the timer 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 diagrams showing one display example of the display unit 19 in the redialing process. By the above-described call processing, each time a call is made, the start date, start time, destination telephone number, destination telephone number, and the like are stored in the redial list of the RAM 18 as shown in FIG. The base station location name, line type (public / home), end date, and end time are stored. Even when a call cannot be made, the same information is stored except for the end date and the end time.

  Here, when the user presses the redial button shown in FIG. 4A, the display unit 19 displays the destination name or the destination telephone number stored in the redial list as shown in FIG. 6A. Is displayed. If the destination telephone number stored in the redial list is already registered in the telephone directory, the destination name (individual name, company name, etc.) stored in the telephone directory is displayed. If it is not in the telephone directory, the destination telephone number stored in the redial list is displayed as it is. In this state, if the party to redial is known, the destination name or the destination telephone number is touched with the touch pen 41. If the destination name or the destination telephone number cannot be displayed on the display unit 19, the cursors 19a and 19b shown are touched with the touch pen 41 to scroll the destination name or the destination telephone number up and down. Just fine. When the destination name or the destination telephone number is touched, the PHS terminal 6 makes a call to the selected destination telephone number and, as shown in FIG. Displays the destination phone number and a message indicating that the call is in progress.

  On the other hand, if the party to be redialed is not clear in the display shown in FIG. 6A, the display is switched to “detailed display” by an instruction from the key input unit 15 or the touch pen 41. 7A and 7B show display examples in the detailed display. FIGS. 7A and 7B are schematic diagrams showing other display examples at the time of redial processing. In the detailed display example shown in FIG. 7A, the start date (4/15) and the start time (AM6: 53) stored in the redial list for one destination as shown in the hatched area A. , End time (10:09), destination base station location name (Shinjuku station west exit), destination name (Yuko Suzuki), destination telephone number (03-1234-5678) are displayed. The destination name (Yuko Suzuki) is obtained by reading and displaying the destination name (individual name, company name, etc.) stored in the telephone directory, as described above.

  In the example shown in FIG. 7A, the line was connected in the previous call, but if the line was not connected even after the call was made, it can be confirmed that the end time is blank. . If the line is not connected even if the call is made, a special character is displayed. If the display unit 19 can display gradation, the gradation is changed. You may distinguish by changing a color. Further, in the display example shown in FIG. 7A, in the lower area B, the destination name is not displayed, and only the destination telephone number is displayed. This is because the destination telephone number is not registered in the telephone directory. If the destination name or the destination telephone number cannot be displayed on the display unit 19, the cursors 19a and 19b shown in the figure may be touched with the touch pen 41 to scroll up and down. In addition, in the state shown in the drawing, if a part of the hatched area A is touched, the call is automatically transmitted to the destination.

  Next, in the detailed display example shown in FIG. 7B, for example, as shown in a hatched area C, the start date (4/14) and the start time stored in the redial list for one destination (AM8: 21), the destination name (Tomoko Ando), and the line type (home) are displayed. If the destination telephone number is not registered in the telephone directory, the destination telephone number is displayed as described above. In addition, if the line is not connected even if the call is made, a special character is displayed, the gradation is changed when the display unit 19 can display the gradation, and the color is changed if the color display can be performed. You may distinguish them by changing them.

  In the above-described embodiment, the display example at the time of the recall is not particularly described. However, in FIGS. 6 and 7, the call destination name or the call destination telephone number is replaced with the call source name or the call source telephone number. The other information is the same. In the above-described embodiment, the information to be stored at the time of calling (or at the time of receiving) includes the start date and time at which the line was connected, the calling telephone number (or calling telephone number), and the location of the base station of the calling. The name (or the base station location name of the source), the line type, the end date, and the end time are given. However, the present invention is not limited thereto. For example, information stored in the source PHS terminal includes The location name of the base station may be stored, or the location name of the destination base station may be stored as information to be stored in the PHS terminal of the destination. In this way, the source PHS terminal knows where the call originated from, and the destination PHS terminal knows where the call arrived, so that not only information about the other party but also information about the own terminal can be obtained. You will be able to know. Furthermore, in the present embodiment, the base station location name and the line type are stored in the database 5a of the base station 5, but the present invention is not limited to this, and may be stored in the database 3 of the network management station 1 or the service management station 2.
