(About phonebook synchronization processing)
In the first embodiment, the telephone directory management APL20 synchronizes all or a part of the telephone directory managed by the server 1 with the telephone directory managed by the telephone directory management APL20 by communicating with the server 1. Has the function of Here, if the number of telephone directories stored in the server 1 is large, it will take time for synchronization. Since the telephone directory management system according to the first embodiment is supposed to manage telephone directories mainly used in a company, the number of telephone directories is likely to be enormous. Therefore, in the first embodiment, among the telephone directories managed by the server 1, only a predetermined number of records may be synchronized with the telephone directory managed by the telephone directory management APL20. More specifically, the synchronization unit 103 of the server 1 and the synchronization unit 203 of the telephone directory management APL20 record a predetermined number of records in the order of frequently used candidates from the telephone directories stored in the server 1, or in advance. A predetermined number of records set as synchronization targets may be synchronized with the telephone directory managed by the telephone directory management APL20.

The telephone directory managed by the server 1 may be divided into a plurality of categories. The plurality of categories are, for example, a telephone directory that stores internal telephone numbers that are commonly used by each employee (for example, the representative number of each department), and external telephone numbers that are commonly used by each employee (for example,). A telephone directory that stores (such as a customer's telephone number) and a telephone directory that stores telephone numbers that each employee personally uses. In this case, the above-mentioned "order of frequently used candidates" may be the order of high usage frequency in the entire plurality of categories, or the order of high usage frequency for each of the plurality of categories. In the former case, a predetermined number of records are synchronized with the phonebook managed by the phonebook management APL20 in the order of frequently used candidates in the entire plurality of categories, and in the latter case, a predetermined number of records are used for each of the plurality of categories. Record will be synchronized with the phone book managed by the phone book management APL20.

The timing at which synchronization is performed may be, for example, a predetermined timing (for example, once a day) or a timing at which the telephone directory managed by the server 1 is updated.

According to the synchronization process described above, it is possible to shorten the time required for synchronization even when the number of telephone directories stored in the server 1 is large.

Further, as will be described in detail later, in the present embodiment, it is also possible to "do not synchronize the telephone directory". However, if the phone book is not synchronized, communication occurs between the server 1 and the terminal 2 every time the phone book needs to be referred, and whether or not the phone book can be referred depends on the communication environment of the terminal 2. Will end up. On the other hand, when synchronizing the phone book, since the phone book is saved in the terminal 2, it is possible to prevent the problem that the referenceability of the phone book depends on the communication environment of the terminal 2. ..

(About the synchronization destination of the phone book)
In the processing procedure described so far, it is assumed that the telephone directory managed by the server 1 is synchronized with the telephone directory managed by the telephone directory management APL20 of the terminal 2. However, depending on the usage pattern of the terminal 2, it is assumed that there is a case where it is desired to secure further convenience, a case where it is desired to further enhance security, or a case where it is desired to consider the communication frequency / communication amount between the server 1 and the terminal 2. Therefore, as shown in FIG. 5, the determination unit 204 of the terminal 2 synchronizes the telephone directory acquired from the server 1 with the telephone directory managed by the telephone directory management APL20 (FIG. 5A), or a standard telephone. Whether to synchronize with the phone book managed by the book APL40 (FIG. 5 (b)) or not to synchronize with any of the phone books (FIG. 5 (c)) is determined based on "predetermined conditions". The synchronization unit 203 may perform the synchronization process according to the determination result. For example, when synchronizing with the phonebook managed by the standard phonebook APL40, the risk of information leakage due to malware increases, but the phonebook can be accessed from other APLs (for example, SNS APLs), which is convenient for users. You can improve your sex. Further, when not synchronized with any of the telephone directories, even if the user loses the terminal 2, the risk that the acquirer of the terminal 2 can refer to the telephone directory can be eliminated. When not synchronizing with any of the telephone directories, in the processing procedure of step S103 in FIG. 4, the notification unit 202 of the telephone directory management APL20 receives a notification of an incoming call from the standard call APL30 and the caller's telephone number each time. Will ask the server 1 for the source user name. Hereinafter, a specific example of the "predetermined condition" when the determination unit 204 determines the synchronization destination will be described. The determination unit 204 may determine the synchronization destination by combining a plurality of the specific examples shown below.

[Specific example of predetermined conditions (1)]
The "predetermined condition" may be a condition based on the schedule information of the user registered in the terminal 2 or the destination (for example, during overseas roaming) grasped by the OS 50. For example, when the destination is overseas, the determination unit 204 manages the phone book management APL20 in consideration of the possibility that the overseas roaming charge will be high due to the acquisition of the phone book from the server 1 each time an incoming call is received. It may be determined that the telephone directory to be synchronized with the telephone directory or the telephone directory managed by the standard telephone directory APL40 should be synchronized. Further, when the destination is overseas, there is a high possibility that it will be difficult to find the terminal 2 if the user loses it. Therefore, the judgment unit 204 should synchronize with the telephone directory managed by the telephone directory management APL20 in consideration of both the risk that the acquirer will refer to the telephone directory and the possibility that the overseas roaming charge will be high. It may be determined.

[Specific example of predetermined conditions (No. 2)]
The "predetermined condition" may be whether or not a specific APL (for example, SNS APL) is installed in the terminal 2. When a specific APL is installed, the determination unit 204 synchronizes with the phone book managed by the standard phone book APL 40 in consideration of improving the convenience of the user by making it possible to refer to the phone book from the specific APL. You may decide that it should be done. On the other hand, when a specific APL is not installed, the determination unit 204 may determine that it should be synchronized with the telephone directory managed by the telephone directory management APL 20. The determination unit 204 acquires the usage frequency (for example, the number of activations, the number of uses, etc.) of the specific APL even when the specific APL is installed, and the frequency of use is low (for example, the number of times of use). (When the number of activations, the number of uses, etc. is equal to or less than a predetermined threshold value) may be determined to be synchronized with the telephone directory managed by the telephone directory management APL20.

[Specific example of predetermined conditions (3)]
The "predetermined condition" may be the security level set in the terminal 2. For example, assuming that the security level is three levels, the determination unit 204 determines that when the security level is set low, it should be synchronized with the telephone directory managed by the standard telephone directory APL40, and the security level is determined. If is set to medium, it should be determined that it should be synchronized with the phonebook managed by the phonebook management APL20, and if the security level is set high, it should be synchronized with any phonebook. It may be determined that there is no such thing.

[Specific example of predetermined conditions (4)]
The "predetermined condition" may be a condition based on the attributes (industry, etc.) of the user who uses the terminal 2. Further, the association between the attribute of the user who uses the terminal 2 and the synchronization destination may be shown in the setting file stored in the terminal 2 in advance. Further, the attributes of the user who uses the terminal 2 may be notified from the server 1 to the terminal 2 at an arbitrary timing, or may be input to the terminal 2 by the user. The determination unit 204 compares the user's attribute notified from the server 1 (or input to the terminal 2) with the setting file, and determines that the synchronization destination should be synchronized with the synchronization destination corresponding to the user's attribute. Become.

[Specific example of predetermined conditions (No. 5)]
The "predetermined condition" may be the synchronization destination instructed by the user. That is, the determination unit 204 may determine that synchronization should be performed with the synchronization destination instructed by the user of the terminal 2.

According to the synchronization destination determination method described above, it is possible to select an appropriate synchronization destination according to the usage pattern of the terminal 2. It is also possible to apply the synchronization process described in "(About the synchronization process of the telephone directory)" to the synchronization process with the synchronization destination determined by the synchronization destination determination method described above.
