On the other hand, the communication terminal 2 updates a communication control unit 21 for transmitting / receiving signals to / from the server 1 as a communication partner, a telephone directory file 23 for storing telephone directory information, and the contents of the telephone directory file 23. A telephone directory rewriting unit 22 is provided.

The above-described communication control unit 11 and communication control unit 2
1 performs control for transmitting and receiving signals via the network 10. From the input unit 12 of the server 1, update types such as “add”, “delete” or “replace”, terminal identification information, and terminal additional information are input as telephone directory update information.

The telephone directory update unit 13 is provided with the above-described telephone directory update information from the input unit 12, performs processing such as addition, deletion, or replacement of the contents of the main file 14 according to the update type among the update information. 15 is written to the area 15-k.

The main file 14 is composed of a plurality of terminal information records and a version number indicating the number of updates. This terminal information record includes a base name given to a branch or a branch office, a terminal number unique to each terminal, and terminal additional information including a place name, a room name, and the like where the terminal is installed.

The "version number" means the history of the telephone directory file being created or modified. That is, when a new version is created, the version number becomes “1”, and each time an update such as addition, deletion, or replacement is made, the version number becomes “2”, “3”, “4”,.・ And one by one.

If the version number is "1", no writing has been made to the difference file 15 since it has not been updated. Therefore, the areas 15-2 and 15-
.. Are respectively written with version number numbers “2”, “3”,.

As described above, the difference file 15 is composed of a plurality of areas 15-k in which update difference records are written, and information in each of these areas 15-k includes an update type, terminal identification information, It consists of additional information.

The telephone directory rewriting section 22 of the communication terminal 2
Based on the update difference record in the telephone directory difference data received from the server 1, the terminal information of the telephone directory file 23 is added, deleted, or replaced for each update type. The telephone directory file 23 has the same configuration as the main file 14 of the server 1.

In this embodiment, when the contents of the telephone directory file are changed, the contents of the main file 14 of the server 1 are changed before the contents of the telephone directory file 23 of the communication terminal 2 are changed. Is written in the difference file 15.

FIG. 3 is a flowchart showing an example of a processing flow when the contents of the telephone directory file are changed in the server 1 of the present embodiment. When changing the contents of the telephone directory file, first, the version number k of the main file 14 is set to 1
Is added (step Sa1).

Further, an area 15-k of the added version number k is set in the difference file 15, and this area 15-k is initialized (erased) so that no difference is recorded (step Sa2). .

Here, as the update information of the telephone directory, the update type and the terminal information to be changed are input from the input unit 12 to the telephone directory update unit 13 (step Sa3). As described above, this update type is a process type of "addition", "change", or "replacement" of terminal information. When the update type is "addition" or "replacement", new terminal information is input. On the other hand, when the update type is “delete”, the current terminal information is input. When the terminal identification information is changed, first, "delete" and then "add" are sequentially supplied as terminal information.

Therefore, the telephone directory update unit 13 first checks whether the input update type is “add” (step Sa).
4) Next, it is checked whether the update type is “delete” (step Sa5), and further, whether it is “replace” (step Sa6).

If the update type is "addition" in step Sa4, the input terminal information is written in the main file 14 as a new terminal information record (step Sa7), and then the terminal identification information (base (Step Sa8), and the process proceeds to Step Sa11 described later.

If the update type is "delete" in step Sa5 described above, the terminal information record that matches the input terminal identification information is deleted from the main file 14 (step Sa9), and a step described later is performed. Move on to the processing of Sa11.

If the update type is "replacement" in step Sa6, a terminal information record that matches the input terminal identification information in the terminal information record of the main file 14 is input. Rewrite with terminal information (step Sa10).

Thereafter, the telephone directory updating unit 13 sends the input
The change type and the terminal information input from the server are written to the difference file 15 as an update difference record (step Sa1).
1) It is confirmed whether there is any other terminal information to be updated (step Sa12). Here, if there is another terminal information to be updated, the process returns to step Sa3, and if not, the process ends.

In this manner, a record of a new telephone directory file is created in the main file 14, and the update history of the telephone directory file up to the present is stored in the area 15 in the difference file 15.
-K are sequentially written.

When the new update history is written in the area 15-k in the difference file 15 as described above, the communication control unit 11 sends the communication control unit 11 to the communication terminal 2 connected (logged on) to the server 1. A configuration in which a new version number is automatically notified may be employed.

FIG. 4 is a diagram showing an example of how such a telephone directory file (main file 14 and difference file 15) is updated. FIG. 4 (a) shows the main state of the version number "1" before the update. FIG. 4B shows the contents of the file 14, and FIG.
FIG. 4C shows the contents of the main file 14 having the version number “2”.

As shown in FIG. 3, when the telephone directory file is updated in the server 1, the contents of the main file 14 shown in FIG. The file is updated based on the contents of the update,
As shown in FIG. 4C, the version number is increased, and the contents of the telephone directory file are changed.

Although the version number of the contents of the main file 14 shown in FIG. 4A is "1", the version number shown in FIG. The difference update record of the number “2” is written, the contents of the main file 14 are changed as shown in FIG. 4C, and the version number is “2”.

At this time, the terminal number "115" in FIG.
9 "has been deleted, but the terminal number" 1201 "has been added as shown in Fig. 4C.
Terminal number “2057” is deleted and the terminal number “203” is deleted.
Although "3" has been added, the order has been rearranged in the order of the base name and the terminal number. Therefore, "East branch office, 2056, General affairs department conference room" is written after "East branch office, 2033, branch office room". ing.

FIG. 5 is a flowchart showing an example of the flow of processing when updating the contents of the telephone directory file 23 of the communication terminal 2. When starting to update the telephone directory file, the communication terminal 2 first logs on (communications connection) from the communication control unit 21 to the communication control unit 11 of the server 1 via the network 10 (step Sb1).

At this time, the communication control section 11 confirms the current version number k of the main file 14 through the telephone directory updating section 13 (step Sc1) and notifies the communication terminal 2 (step Sc2).

The telephone directory rewriting unit 22, which has received the notification of the version number k from the server 1 via the communication control unit 12, checks whether the version number k matches the version number m of the telephone directory file 23. It is confirmed whether or not it is (step Sb2), and if they match, the process proceeds to a normal communication process.

On the other hand, the version number k received from the server 1
If the version number m of the telephone directory file 23 does not match the version number m of the telephone directory file 23,
Request transmission of +1 telephone directory difference data (step S
b3).

When the communication control unit 11 of the server 1 receives this request, it sends the difference file 15
The content of the area 15- _{m + 1} is returned (step Sc3).
The returned telephone directory difference data is input to the telephone directory rewriting unit 22 via the communication control unit 21, and the telephone directory rewriting unit 22 updates the telephone directory file 23 based on the telephone directory difference data (step Sb4). The process returns to step Sb2.

FIG. 6 is a flowchart showing a detailed processing procedure of step Sb4 shown in FIG. When the telephone directory difference data is input from the communication control unit 21, the storybook rewriting unit 22 of the communication terminal 2 sequentially reads updated difference records from the top of the input telephone directory difference data (step Sd).
1).

Here, first, it is confirmed whether or not the inputted update type is "addition" (step Sd2), then, it is confirmed whether or not the update type is "deletion" (step Sd3). It is confirmed whether or not (step Sd4).

If the update type is "addition" in step Sd2, the input terminal information is written as a new terminal information record in the telephone directory file 23 (step Sd5), and then the terminal identification information ( The order is rearranged in the order of (base name and terminal number) (step Sd6), and the process proceeds to step Sd9 described later.

If the update type is "delete" in step Sd3 described above, the terminal information record that matches the input terminal identification information is deleted from the telephone directory file 23 (step Sd7), and will be described later. The process moves to step Sd9.

If the update type is "replace" in step Sd4, the telephone directory file 23
In the terminal information record of (1), the terminal information record that matches the input terminal identification information is rewritten with the input terminal information (step Sd8).

Thereafter, the telephone directory rewriting section 22 checks whether or not all updates of the update difference data have been completed (step Sd9), and if not completed, returns to the processing of step Sd1, and reads the next data. . When all the update difference data has been updated, 1 is added to the version number of the telephone directory file 23 (step Sd10), and the process ends.
