When there is no corresponding destination data in the RAM 18 when making a call with the HS terminal 6, the database 3 is automatically transmitted to the PHS terminal 6.

B. Operation of Embodiment Next, the operation of the PHS terminal according to the above-described embodiment will be described. In the following description, the operation of each unit associated with a call is the same as the operation of a normal PHS terminal, and thus the description thereof is omitted. B-1. Phonebook Registration Process First, the operation of the PHS terminal according to the above-described embodiment when registering the phonebook will be described. FIG. 5 is a flowchart for explaining the operation at the time of registering the telephone directory.
When the user selects the phonebook registration mode on the PHS terminal 6, first, in step S10, the user is prompted to
Make the recipient's name read, enter the name and phone number, and create the recipient's data. The name reading, the name, and the telephone number are input by, for example, writing on the display unit 19 with the touch pen 41 (handwriting recognition) or inputting by selecting a character displayed on the display unit 19. Method may be used.

When the data input is completed, next, in step S12, a connection request is issued to the nearby radio base station 5, and when the line is connected, the data of the transmission destination is transmitted. On the other hand, on the telephone communication network 4 side, step S3
At 0, the data of the transmission destination transmitted via the wireless base station 5 is received. Next, in step S32, the data of the destination such as the received telephone number is stored in the database 3. In step S36, the PHS terminal 6 sends a confirmation code indicating that the storage of the data of the transmission destination is completed.
To end the process.

On the other hand, on the PHS terminal 6 side, step S1
In step 4, the confirmation code is received, and step S16
Go to. In step S16, the free capacity of the RAM 18 (area for telephone directory) is checked. Next, step S1
At 8, it is determined whether or not there is free space. If the RAM 18 has a free space, the result of the determination in step S18 is "YES", and the process proceeds to step S24. In step S24, the input destination data is stored in the RAM 18 in the format shown in FIG. 4A, and the process ends.

On the other hand, if the RAM 18 has no free space,
That is, when N preset destination data has already been stored, the determination result in step S18 is "NO", and the process proceeds to step S20.
In step S20, the frequency of use of the destination data (telephone number) already stored in the RAM 18 is checked. Then, in step S22, the data of the destination whose usage frequency is the lowest is erased and a free space is created in the RAM 18. Next, the process proceeds to step S24 described above, the newly input data is stored in the RAM 18, and the process ends. In addition, step S16 on the PHS terminal 6 side described above.
~ S24 is a "registration process" that is also executed in the data search / transmission process described below.

As described above, in the telephone directory registration process, the PHS
Destination data such as a telephone number newly input at the terminal 6 is stored in both the PHS terminal 6 and the database 3 on the telephone network side. At this time, in the PHS terminal 6,
If there is no free space in the RAM 18, the data of the destination with the lowest frequency of use is erased and new data is stored. Even if the data of the destination with the lowest frequency of use is deleted, this data is stored in the database 3 on the telephone line network 4 side.
If you read it into, no trouble will occur.

B-2. Data Retrieval / Distribution Processing According to Embodiment Next, the operation of the data retrieval and transmission processing according to this embodiment will be described. FIG. 6 is a flowchart for explaining the operation of the data search and transmission processing. When the user selects the transmission mode, first, in step S40, as shown in FIG.
From the character string displayed in, enter the first letter (reading) of the name of the person you are calling as the search character. For example, when the name of the destination is beginning with the "sa" line, the "sa" portion in the figure may be touched with the touch pen 41. Next, in step S42, the RAM 18 in the PHS terminal 6 is searched based on the search character. The search is performed by comparing the search character with the initials of the name reading shown in FIG. In step S44, as a result of the search, it is determined whether or not there is the corresponding data (data of the transmission destination). If there is the corresponding data, the determination result in step S44 is "YES", and the process proceeds to step S46.

In step S46, as shown in FIG. 7B, the data of the corresponding destination is displayed on the display unit 19. The display unit 19 displays all names of the destinations that match the search character. In the illustrated example, all the names of the callee starting with the "sa" line are displayed. In this state, if the cursors (icons) 19a and 19b are touched with the touch pen 41, the display scrolls upward or downward, and other names not displayed can be seen. Next, in step S48, the user is made to select the name of the re-thinner who is about to make a call. Figure 7 shows the selection of names.
This is performed by touching the hatched portion shown in (b) with the touch pen 41. In the illustrated example, “Kenji Sato” is selected. When the user selects the name of the call destination, the process proceeds to step S50 and the call is made according to the selected telephone number of the call destination. At the time of making a call, as shown in FIG. 8A, the name and telephone number of the called party are displayed on the display unit 19. Then, in step S52, the frequency of use of the destination data is updated (incremented), and the process ends. After the call is made, if the line is connected, a call is made with the callee.

On the other hand, if there is no corresponding destination data in the RAM 18 of the PHS terminal 6, the result of the determination in step S44 is "NO", and the flow advances to step S54. In step S54, a connection request is issued to the nearby wireless base station 5, and when the line is connected, the search character input in step S40 is transmitted. On the other hand, on the telephone line network 4 side, the search character is received in step S80, and the process proceeds to step S82. In step S82, the database 3 is searched based on the search character. The search is performed by comparing the search character with the initials of the name reading shown in FIG. Next, in step S84, as a result of the search, it is determined whether or not there is data of the corresponding destination. If there is the corresponding data, the determination result in step S84 is "YES", and the process proceeds to step S86. Step S
At 86, the data of the corresponding destination is transmitted to the PHS terminal 6 via the wireless base station 5. At this time, since the search is performed using the initials of the name reading, a plurality of data may be applicable. Therefore, in step S86, only the name of the corresponding data is transmitted.

The PHS terminal 6 receives the data from the telephone line network 4 in step S56. At this time, in addition to the above-described data (name), the transmitted data includes a confirmation code indicating that there is no corresponding destination data, as will be described later. In step S58,
It is determined whether the received data has the above name or the confirmation code. If it is the data (name) corresponding to the search character, the determination result in step S58 is "YES", and the process proceeds to step S60.
In step S60, as described above, the received data (name) is displayed on the display unit 19 as shown in FIG. 7B. Next, in step S62, the user is made to select the name of the callee who is about to make a call. As described above, the name is selected by touching the hatched portion shown in FIG. 7B with the touch pen 41. When the user selects the name of the destination, step S
Proceeding to 64, the name of the selected destination is transmitted to the telephone line network 4.

On the other hand, on the telephone network 4 side, in step S90, the name of the callee is received from the PHS terminal 6, and in step S92, the data corresponding to the name (name of the remaining data Read and send the phone number). The PHS terminal 6 receives the data (name reading, telephone number) in step S66.
Next, in step S68, the call is made according to the telephone number of the callee. When making a call, as shown in FIG. 8A, the name and telephone number of the callee are displayed on the display unit 19. Next, the process proceeds to step S70, and the usage frequency of the destination data is updated (incremented). Then, in step S72, the same processing as the above-described registration processing (steps S16 to S24 shown in FIG. 5) is performed.

That is, first, the free space of the RAM 18 (area for telephone directory) is checked (step S16), and it is determined whether or not there is free space (step S18). Then, if there is a free space in the RAM 18, the received destination data is stored in the RAM 18 in the format shown in FIG. 4A (step S24), and the process ends. On the other hand, RA
If there is no free space in M18, that is, if N preset destination data are already stored, the usage frequency of the destination data already stored in RAM 18 is checked. (Step S20) Then, the data of the destination whose usage frequency is the lowest is erased and a free space is created in the RAM 18 (step S22). Then, the newly input destination data is stored in the RAM 18 (step S24), and the process ends.

On the other hand, on the telephone line network 4 side, if the destination data corresponding to the search character is not in the database 3, the determination result in step S84 is "NO", and the process proceeds to step S88. In step S88, a confirmation code notifying that there is no corresponding destination data is transmitted to the PHS terminal 6. In this case, in the PHS terminal 6, the determination result in step S58 is "NO", and the process proceeds to step S74. In step S74, as shown in FIG.
As shown in (b), after displaying that there is no data of the corresponding destination on the display unit 19, the process ends. If there is no corresponding destination data, the user performs the above-described registration process to newly register or directly operates the dial button 31 to make a call.

As described above, in the data retrieval / transmission process, first, the RAM 18 of the PHS terminal 6 is retrieved, and if there is data of the relevant destination, the data is originated based on the telephone number and the telephone is called. The frequency of use of the number is updated. On the other hand, if the PHS terminal 6 does not have the destination data, the database 3 on the telephone network 4 side is searched, and the data of the relevant destination is read before transmission. The destination data once read is stored in the RAM of the PHS terminal 6 as it is.
18 is stored. At this time, if the specified number of cases has already been stored, the one with the lowest frequency of use is deleted and stored. Therefore, even if the PHS terminal 6 side does not have the data of the corresponding destination, the data is automatically read from the communication line network, so that the call can be transmitted without the user being aware of the operation and making the operation complicated. It can be carried out.

In the above-described embodiment, all the data of the destination is stored in the database 3 of the telephone network 4, while only the frequently used data is stored in the PHS terminal 6, so that The memory on the side can be minimized, the telephone number of the callee can be efficiently read even at the time of calling, and the search time can be minimized.

In the above-described embodiment, the database 3 does not store the frequency of use for the data of each destination, but the frequency of use may be stored. In this case, the PHS is used. When erasing the less frequently used data on the terminal 6 side, the usage frequency of the data of the destination is stored in the database 3. By doing so, for example, when the destination data, that is, the telephone directory is lost on the PHS terminal 6 side, the most frequently used destination data among the destination data stored in the database 3 is N If the case is transferred to the PHS terminal 6, it can be used as a backup of the telephone directory.

Further, in the above-mentioned embodiment, all the data of the telephone directory is stored in the database 3, but the present invention is not limited to this, and may be a memory provided in the wireless base station 5, for example, a telephone line network. Any place above 4 is fine.
