Description

  The present invention relates to a presence update method, a telephone set, and a program that are suitable for application when, for example, contact is made at a destination even when the other party moves.

  Conventionally, a unique number is assigned to a line in an NGN (Next Generation Network) that communicates by packet switching or a fixed telephone that communicates by circuit switching. For example, a telephone number such as “03-1234-5678” is assigned to a telephone number of an office or the like having a base in the Tokyo area. Then, a user who makes a call can talk with the other party by pressing a numeric button or the like provided on the telephone and inputting a telephone number.

Patent Document 1 discloses a telephone relay system that enables a terminal having a plurality of telephone numbers to make and receive calls in the same manner as a terminal having only one telephone number.
JP 2007-151081 A

  By the way, when the telephone receiver moves to a different base, the telephone caller has to check the telephone number of the destination of the telephone receiver. Currently, in order to check the destination telephone number, the telephone number of the destination must be heard from the telephone recipient.

  Also, for example, there is a case where the other party holds a mobile phone or the like and makes a call to this mobile phone number. However, when the other party is in the basement where the radio wave of the mobile phone does not reach, or when the other party is working in a place where it is prohibited to bring in the mobile phone, it is difficult to contact directly.

  Also, the telephone number management database that manages the telephone number of the destination is not frequently updated. For this reason, it was impossible to accurately grasp the destination telephone number. In recent years, many companies have become open offices, and there is a situation where the seats do not match the seated people. Such a situation is very complicated when, for example, the partner frequently travels and is often absent.

  The present invention has been made in view of such a situation, and an object thereof is to allow a user to make a call without knowing the other party's telephone number.

  The present invention updates the data managed by the first and second telephones connected to the communication line and the presence management server. Then, presence information including information on a user who uses the first telephone and a telephone number assigned to the first telephone is sent from the first telephone to the presence management server. Then, presence information is registered in the first telephone directory database provided in the presence management server. The second telephone is notified of the presence information registered in the telephone directory database. Also, the notified presence information is registered in the second telephone directory database provided in the second telephone.

  This makes it possible to make a call even if the user does not know the other party's telephone number.

  According to the present invention, the information on the user who uses the first telephone and the presence information including the telephone number assigned to the first telephone are registered in the presence management server. Then, the presence information notified from the presence management server is registered in the second telephone directory database included in the second telephone. Therefore, a user who uses the second telephone can make a call to the other party without being aware of the telephone number of the user who uses the first telephone.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the present embodiment, NGN (Next Generation Network) line is used as a telephone line, presence information (for example, user identification information for identifying a user who uses a telephone, and a telephone assigned to the telephone used by the user) An example applied to the presence management system 1 capable of dynamically managing (number) will be described.

  The presence management system 1 includes a presence management server 2 that acquires presence information and manages the presence information, and a user management database 3 that manages a telephone number of each user. The presence management server 2, the first telephone set 11 and the second telephone set 5 having a function capable of making a call to the other party are connected by a secure communication line 4, and data transmitted / received to / from each other is protected. The user's personal information (identification ID, personal identification number, user name, access authority, etc.) is recorded in the authentication device 18 in which user identification information for uniquely identifying the user who uses the telephone is recorded. The communication line 4 is a line such as a LAN (Local Area Network) that can be connected to the Internet.

  The presence management server 2 manages the telephone numbers of the first telephone set 11 and the second telephone set 5 installed in the place where each user is present for each user. When the user uses the first telephone 11, a message including presence information is sent from the first telephone 11 to the presence management server 2. This message is described, for example, in the form of an XML (Extensible Markup Language) document. This message includes a request for updating / deleting a telephone number used by the user. The presence management server 2 registers the presence information included in the received message in a telephone directory database to be described later. The presence management server 2 transmits a response message to the first telephone 11 as information on the result of the received request message.

  This response message includes information regarding normality and abnormality when the presence management server 2 accesses the telephone directory database. In addition, the presence management server 2 is notified of the presence information registered in the telephone directory database to the second telephone 5. The notified presence information is registered in the telephone directory database of the second telephone 5. However, presence information may be acquired for each call without registering presence information.

  When registering and deleting presence information (hereinafter also simply referred to as “update”) with respect to the presence management server 2, the authentication device 18 is used to authenticate the user. In addition, access or reference to a telephone number is not allowed except for access made by a user or authorized person. Also, when searching from the user name, access by anyone other than authorized persons is prohibited.

  Consider a case where a first user using a first telephone makes a call to a second user using a second telephone. At this time, the presence management server 2 searches using the second user name as a key, and reads the telephone number registered in the presence management server 2 by the second user. Then, the presence management server 2 notifies the first telephone 11 of the read telephone number. As a result, the first user can make a call by calling the second user.

  The communication line 4 is directly connected to the presence management server 2 via an in-house LAN or the like where the first telephone 11 is installed. The communication line 4 is connected by, for example, HTTPS (Hypertext Transfer Protocol Security). The communication line 4 is connected through a plurality of routers, servers, etc. in the middle of the route. Data flowing through the communication line 4 is encrypted by SSL or the like, and the contents cannot be read by a device on the way.

Here, NGN will be described.
The NGN is a network that can be controlled by a SIP (Session Initiation Protocol) protocol. NGN integrates the IP network for internet service and the telephone network for telephone service, which are constructed separately, into an IP communication network with improved QoS (Quality of Service) and security using IP technology. This is a next-generation IP network that replaces the network. There is also a movement to provide not only telephones but also TV broadcasts over an IP network.

  In order to open a session, SIP provides a function for specifying a communication partner and a function for outgoing / incoming / disconnected. SIP expresses a message, that is, communication data in a text format. This system using SIP is largely composed of a user agent and a SIP server. The user agent is a SIP terminal such as a PC having a so-called IP (Internet Protocol) telephone function. This user agent includes a user agent client having a function of transmitting a request and a user agent server having a function of responding to the request.

  SIP has been studied as a technology necessary for integrating a telephone network into an IP network. Therefore, as an important function of the SIP system, there is ENUM (E.164 Number Mapping) that can use a conventional telephone number in various IP network applications such as an IP telephone.

  The standardization of ENUM is being worked on jointly by IETF and ITU-T. In terms of cooperation between ENUM and SIP, there are ENUM search by the SIP terminal (first telephone 11) and ENUM search by the SIP server (presence management server 2).

  ENUM is a technology that associates a telephone number with an address or service on the network and uses it as an access means. An internationally unique telephone number system (called "E164") and a special domain area (a subdomain of ".e164.arpa") established by ITU-T (International Telecommunication Union) By associating with, the telephone number is associated with the service or address on the network. There may be a plurality of addresses corresponding to one number. For example, if the user's telephone number is associated with an e-mail address, FAX number, website URL, etc. by ENUM, the telephone number can be used as a unified identification number for access means to the user. For example, the domain name of ENUM (E164 number) corresponding to the telephone number “03-1234-5678” is arranged in the reverse order by replacing the leading 0 with the country code 81 of Japan, in “8.7.6.5.4.3.2.1. 3.1.8.e164.arpa ". The address corresponding to this DNS record is stored in the presence management server 2 and the first telephone 11.

  Such an ENUM function allows a user to use various IP network applications by using a conventional telephone number without any particular awareness.

FIG. 2 shows an example of the external configuration of the first telephone 11.
The first telephone 11 includes a receiver 12 having a speaker 12a that emits voice and a microphone 12b that picks up the voice of the speaker, and a selection menu screen for selecting presence information such as the telephone number of the other party and a party to call. The display unit 13 for displaying the information, the selection unit 14 for selecting the other party to call from the selection menu screen displayed on the display unit 13, and the state (presence information) of the user who uses the first telephone 11 An authentication device reading unit 16 that reads user identification information from a presence key 15 for identification, and an authentication device 18 in which user identification information for uniquely identifying a user who uses the first telephone 11 is recorded, a telephone number, and the like And a number key 17 capable of selecting “0” to “9”, “*”, and “#”. The authentication device reading unit 16 may be an external device of the first telephone 11. Presence information notified to the presence management server 2 when the user presses the presence key 15 includes states such as “logout”, “currently enrolled”, “out of seat”, “meeting”, and the like.

  The first telephone 11 can specify a user who uses the first telephone 11. A user who uses the first telephone 11 is specified when the authentication device 18 is held over or inserted into the authentication device reading unit 16, for example. For this reason, the user can easily update the telephone number registered in the presence management server 2 to the telephone number assigned to the first telephone 11 installed in the place where the user is present. In this example, the state in which the authentication device 18 is set in the first telephone 11 and the user is authenticated by the presence management server 2 is the state in which the presence management system 1 is logged in. When logged in, the presence management server 2 determines that the use of the first telephone 11 has started. On the other hand, a state where the authentication device 18 is removed from the first telephone 11 (or a state where “logout” of the presence key 15 is pressed) is a state where the user is logged out from the presence management system 1. When logged out, the presence management server 2 determines that the use of the first telephone 11 has been stopped.

  The authentication device 18 can prevent illegal rewriting of the telephone number from the outside by using the public key cryptosystem. When the authentication device 18 is used, mutual authentication between the user and the presence management server 2 can be performed, and data communication can be used safely. Therefore, unauthorized access to the presence management server 2 can be prevented. Furthermore, various functions can be added to the authentication device 18 by using metadata or the like as accompanying information.

Further, all log information generated when the first telephone 11 and the second telephone 5 are used can be stored in the telephone directory database 50. It is also possible to search for a user who uses the first telephone 11 and the second telephone 5 from the log recorded in the telephone directory database 50. For this reason, since it is possible to determine whether or not an unauthorized user has used the first telephone 11, it is possible to strictly manage user access.

Here, usage examples of the presence management system 1 will be described with reference to FIGS. In the following description, the user A always carries the authentication device 18.
FIG. 5 shows a case where user A is in the first branch.
The first telephone 11 is installed in the first branch. Similarly, the second telephone 5 is installed in the second branch. The first telephone 11 and the second telephone 5 are connected to the presence management server 2 via the Internet (communication line 4). The first telephone 11 and the second telephone 5 are connected to an NGN management center 61 that manages NGN via a normal telephone line. The NGN management center 61 is a base station that manages information necessary for NGN and the like, and has a function as an exchange used when making a normal telephone call.

When the user A uses the first telephone 11, the first telephone 11 is caused to read the user information of the authentication device 18.
However, in FIG. 5, since the user A has removed the authentication device 18 from the first telephone 11, the presence management server 2 determines that the user A has not logged in (in other words, logged out). ing. In this case, the user A is considered to be away.

FIG. 6 shows a case where the user A is moving from the first branch to the second branch.
At this time, the user A is not present at either the first branch or the second branch. For this reason, the presence management server 2 determines that the user A is not logged in. When the user A is moving, the presence management server 2 may notify each phone of the phone number of the mobile phone held by the user A as a phone number that can be contacted with the user A.

FIG. 7 shows a case where the user A is in the second branch.
At this time, the user A logs in to the presence management system 1 by holding the authentication device 18 over the second telephone 5 in order to use the second telephone 5. For this reason, the presence management server 2 determines that the user A is logged in. Then, the presence management server 2 notifies each telephone that the user A uses the second telephone 5. As a result, when another user calls the user A, the user can make a call with the second telephone 5.

  Next, an example of processing of the presence management server 2 and the first telephone 11 will be described with reference to FIGS. However, since the processes of the presence management server 2 and the second telephone 5 are the same as the processes described below, detailed description thereof is omitted.

  FIG. 8 shows an example of processing for registering the telephone number assigned to the first telephone 11 in the presence management server 2. As described above, the user management database 3 includes the telephone directory database 50. Further, the phone book database 50 includes a user management table 51. In the user management table 51, telephone numbers that can be contacted are registered for each user. In this example, before the registration process is performed, the telephone number of user A is registered as “none”. At this time, the user A is absent and cannot be contacted.

  When the user A holds the authentication device 18 over the first telephone 11 and presses the login key, the user A is logged in to the presence management system 1. The user information for identifying the user A includes the telephone number of the first telephone 11 and information recorded in the authentication device 18. Then, registration / update information for registering user information is sent from the presence management server 2 to the presence management server 2. Then, the telephone number of the user A registered in the user management table 51 is registered and updated to “03-XXXX-XXXX”.

FIG. 9 shows an example of processing for registering a telephone number.
First, the first telephone 11 acquires user information recorded in the authentication device 18 (step S1). Then, the first telephone 11 acquires telephone number metadata for registering the telephone number in the presence management server 2 (step S2). The telephone number metadata includes information on a telephone number assigned to the first telephone 11.

  Next, the first telephone 11 requests the authentication device 18 for a signature using a public key cryptosystem (step S3). In response to the request from the first telephone set 11, the authentication device 18 sends the signature data held by itself to the first telephone set 11 (step S4). The signature data includes certificate data for certifying the user. Thereafter, the first telephone 11 starts encrypted communication with the presence management server 2. In the process of step S4, the input password or the like may be included in the signature data by the user's key input.

  Next, the first telephone 11 sends a request message for updating user information to the presence management server 2 together with the signature data (step S5). Then, the presence management server 2 determines from the received request message and the signature data which type of request message the user A has a legitimate access authority (step S6).

  When the presence management server 2 determines that the user A has a legitimate access authority and determines that the message is a registration request message, the presence management server 2 registers and updates the telephone number of the user A recorded in the user management database 3. An instruction is issued (step S7). The user management database 3 notifies the presence management server 2 of the update result information (step S8). This update result information includes information on whether the update has succeeded or when the update has failed.

  Then, the presence management server 2 sends a reply message including the update result information to the first telephone 11 (step S9). As a result, the first telephone 11 can know whether or not the telephone number for which registration has been requested has been registered in the presence management server 2.

FIG. 10 shows an example of a registration / update request message sent from the first telephone 11 to the presence management server 2.
This message includes information indicating that the name of the user A is “Alice”, for example, and the telephone number registered in the user management database 3 is “03-XXXX-XXXX”.

FIG. 11 shows an example of a reply message when registration / update is successful, which is sent from the presence management server 2 to the first telephone 11.
This message includes, for example, a code value “200” indicating that the user information has been successfully registered / updated in the user management database 3. The first telephone 11 reads this code value “200” from the reply message, and determines that the registration / update of the user information is successful.

FIG. 12 shows an example of a reply message when registration / update failure is sent from the presence management server 2 to the first telephone 11.
This message includes, for example, a code value “401” indicating that registration / update of user information with respect to the user management database 3 has failed. The first telephone 11 reads this code value “401” from the reply message, and determines that the registration / update of the user information has failed.

  FIG. 13 shows an example of processing for deleting the telephone number of the first telephone 11 registered in the presence management server 2.

  When the user A presses the authentication device 18 with the logout key of the first telephone 11 and removes the authentication device 18, the user A is logged out from the presence management system 1. At this time, a deletion request message for deleting user information from the presence management server 2 is sent to the presence management server 2. Then, the telephone number “03-XXXX-XXXX” of the user A registered in the user management table 51 is deleted and updated to “none”.

FIG. 14 shows an example of processing for deleting a telephone number.
When the logout key of the first telephone 11 is pressed on the authentication device 18 by the user A, the first telephone 11 acquires the user information recorded on the authentication device 18 (step S11). Then, the first telephone 11 acquires telephone number metadata for deleting the telephone number from the presence management server 2 (step S12).

  Next, the first telephone 11 requests the authentication device 18 for a signature using a public key cryptosystem (step S13). In response to the request from the first telephone set 11, the authentication device 18 sends the signature data held by itself to the first telephone set 11 (step S14). Thereafter, the first telephone 11 starts encrypted communication with the presence management server 2.

  Next, the first telephone 11 sends a request message for updating user information to the presence management server 2 together with the signature data (step S15). Then, the presence management server 2 determines from the received request message and the signature data which type of request message the user A has a legitimate access authority (step S16).

  If the presence management server 2 determines that the user A has a legitimate access authority and is a phone number deletion request message, the presence management server 2 deletes and updates the phone number of the user A recorded in the user management database 3. An instruction is issued (step S17). The user management database 3 notifies the update information to the presence management server 2 (step S18). This update result information includes information on whether the update has succeeded or when the update has failed.

  Then, the presence management server 2 sends a reply message including the update result information to the first telephone 11 (step S19). As a result, the first telephone 11 can know whether or not the telephone number requested to be deleted has been deleted from the presence management server 2.

  FIG. 15 is an example of a process for making a call.

  When the user A makes a call, the authentication device 18 is set in the first telephone 11 and is logged into the presence management system 1. And the other party (user B) displayed on the display part 13 of the 1st telephone 11 is selected, and a call origination request | requirement is performed. At this time, the presence management server 2 searches whether the telephone number of the user B is registered in the user management table 51. If the user B's telephone number is registered in the user management table 51, the telephone number is sent to the first telephone 11. As a result, the user A can make a call to the user B. Note that calling the other party is also called “calling”. In addition, a call to the other party's telephone is also called “incoming call”.

FIG. 16 shows an example of processing for searching for a telephone number.
The first telephone 11 searches the telephone directory database 32 for the other party (user B) selected by the user (step S21). The selection of the user B is performed by the user A via a user selection menu screen displayed on the display unit 13, for example.

  Next, the first telephone 11 requests the authentication device 18 for a signature using a public key cryptosystem (step S22). In response to the request from the first telephone set 11, the authentication device 18 sends the signature data held by itself to the first telephone set 11 (step S23). Thereafter, the first telephone 11 starts encrypted communication with the presence management server 2.

  Next, the first telephone 11 sends a request message for searching for user information to the presence management server 2 together with the signature data (step S24). Then, the presence management server 2 determines from the received request message and signature data which type of request message the user A has a legitimate access authority (step S25).

  When the presence management server 2 determines that the user A has a legitimate access right and is a telephone number search request message, the presence management server 2 instructs to search for the telephone number of the user A recorded in the user management database 3. (Step S26). The user management database 3 notifies the search result information to the presence management server 2 (step S27). This search result information includes information on either a successful search or a failed search.

Then, the presence management server 2 sends a reply message including search result information to the first telephone 11 (step S28). As a result, the first telephone 11 acquires the telephone number of the user B who requested the search.
Then, the first telephone 11 makes a call to the telephone number acquired from the presence management server 2 (step S29).

FIG. 17 shows an example of a telephone number search request message sent from the first telephone 11 to the presence management server 2.
This message includes information indicating that the name of the user B to be searched is “Alice”, for example.

FIG. 18 shows an example of a telephone number search request message sent from the presence management server 2 to the first telephone 11.
This message includes, for example, the code value “200” indicating that the search of the user B is successful with respect to the user management database 3 and the telephone number “03-XXXX-XXXX” of the user B. The first telephone 11 reads this code value “200” from the reply message, and determines that the telephone number search is successful.

  FIG. 19 shows an example of processing for registering the other party's telephone number in the telephone directory database 32 of the first telephone 11 based on the result of the presence management server 2 searching for the telephone number. Here, the case where the telephone number of the user C is registered will be described. As described above, the first telephone 11 includes the telephone directory database 32. Further, the phone book database 32 includes a user management table 33. In the user management table 33, telephone numbers that can be contacted are registered for each user. In this example, before the registration process is performed, the telephone number of user C is registered as “06-WWWW-WWWW”.

  When the first telephone 11 requests the presence management server 2 to search for the telephone number of the user C, the presence management server 2 sends information for updating the telephone number of the user C to the presence management server 2. Then, the first telephone 11 updates the telephone number of the user C registered in the user management table 51 to “06-ZZZZ-ZZZZ”.

FIG. 20 shows an example of processing for updating the telephone directory database 32.
The first telephone 11 detects that the update process of the telephone directory database 32 has been selected by the user (step S31).

  Next, the first telephone 11 requests the authentication device 18 for a signature using a public key cryptosystem (step S32). In response to the request from the first telephone set 11, the authentication device 18 sends the signature data held by itself to the first telephone set 11 (step S33). Thereafter, the first telephone 11 starts encrypted communication with the presence management server 2.

  Next, the first telephone 11 sends a request message for searching for user information to the presence management server 2 together with the signature data (step S34). Then, the presence management server 2 determines from the received request message and signature data which type of request message the user A has a legitimate access authority (step S35).

  When the presence management server 2 determines that the user A has a legitimate access authority and is a telephone number search request message, the presence management server 2 instructs to acquire the telephone number of the user C recorded in the user management database 3. (Step S36). The user management database 3 notifies the search result information to the presence management server 2 (step S37). This search result information includes information on either a successful search or a failed search.

Then, the presence management server 2 sends a reply message including search result information to the first telephone 11 (step S38). As a result, the first telephone 11 acquires the telephone number of the user C who requested the search.
Then, the first telephone 11 updates the telephone number database 32 based on the telephone number acquired from the presence management server 2 (step S39).

FIG. 21 shows an example of a telephone number update request message sent from the first telephone 11 to the presence management server 2.
This message includes information indicating that the telephone directory database 32 is to be updated.

FIG. 22 shows an example of a telephone number update reply message sent from the presence management server 2 to the first telephone 11.
This message includes a telephone number for each user managed by the user management database 3 and presence information. In addition, a code value “200” indicating that acquisition of user information is successful is included. Therefore, the first telephone 11 reads this code value “200” from the reply message and determines that the user information has been acquired. Then, the acquired telephone number is registered in the telephone directory database 32.

  By the way, the cooperation process of a Web application can be linked with various applications by adding accompanying information or the like using XML or the like which is a general-purpose format. For example, an in-house telephone directory system can be browsed on the Web in cooperation with a Web server, or used for calling from an application. In addition, even a device that does not support Dynamic Number Service can search for a telephone number if a Web browser can be used.

  Then, at the same time as updating the telephone number, the accompanying information is registered in the presence management server 2. For this reason, it is possible to grasp where the user is and in what state. Further, by using a standard data format such as XML, it has high extensibility. Then, applications having various functions can be added.

  Further, the telephone number registered in the presence management system 1 is not limited to a fixed telephone. For example, various forms such as initial registration of a mobile phone number or registration of an IP phone number can be considered during movement. In addition, when the user cannot operate the telephone, access restriction can be performed at multiple levels such as system administrator, group administrator, agent, etc. so that a person other than the user can manually update the telephone number. Is possible.

  The presence management system 1 has different possible operations depending on the user's authority. For example, in the case of a system administrator who manages the presence management system 1, all user data can be updated. In the case of a group manager arranged for each company or department, user data in the management group can be updated. Each user can update only his / her own data. When the user sets an agent, the agent can update the requested user's data. As a situation for setting an agent, the latest presence information can be updated to the presence management server 2 even when the user cannot directly operate the presence management system 1 due to a business trip or the like.

FIG. 23 shows an example of cooperation processing with presence information.
FIG. 23A shows a case where the user A is present at the branch office A.
At this time, the presence information of the user A indicates that the user A is in the A4 table on the 21st floor of the branch office A.
FIG. 23B shows a case where the user A is present at the branch office B.
At this time, the presence information of the user A indicates that the user A is in the G2 table on the 10th floor of the branch office B.

  Thus, by managing not only the telephone number to which the user A has moved but also where the user is present as presence information, the location management of the user A can be reliably performed.

  In the presence management system 1 according to this embodiment described above, the presence management server 2 that manages presence information using each telephone is prepared, and an authentication device 18 that can perform personal authentication is used. Therefore, the caller can search based on the name of the other party and obtain the phone number. By calling this telephone number, it is possible to easily call the intended party. The person receiving the call can also receive the call at any time without telling the other party the phone number currently in use.

  Then, the presence management server 2 searches the other party's telephone number and notifies the user of the telephone number. For this reason, the user can make a call without knowing the telephone number of the other party's destination. That is, it can be said that presence information including a user's telephone number and the like can be registered easily and safely, and can be safely disclosed to authenticated users. Further, even if the location function is NGN, fixed phone, IP phone, etc., the user can easily talk with the other party. In addition, since the telephone number of the telephone used by the user can be registered in the presence management server 2 using the authentication device 18, the user does not need a complicated operation. Since the authentication device 18 is used, presence information can be updated or acquired with increased security.

  The presence management system 1 can manage user access restrictions in a plurality of stages. In addition, since the message used for data transmission / reception between the first telephone 11 and the presence management server 2 uses metadata, standard XML, or the like, it is easy to cooperate with a Web server or various application servers. By using metadata, which is accompanying information, for example, information that can identify the current location (the location of the fixed phone if a fixed phone) can be registered and used in devices or other databases, or the current status It is also possible to update in real time (during capture, on the phone, etc.).

  In addition, the telephone directory database of the telephone is automatically updated every predetermined time (for example, once an hour). Moreover, what is necessary is just to update once per week about the user with a long absence period. In addition, when updating the telephone directory database that the telephone has, the presence management server 2 can change the number of pieces of presence information included in messages sent to the telephone, one by one or every ten.

  Further, in the presence management system 1 according to the present embodiment, data is transmitted and received using IP data. The IP data is also used by NGN, and the presence management system 1 and NGN can easily cooperate with each other. For this reason, a special apparatus for cooperating with NGN is unnecessary, and the cost merit is excellent.

  In the presence management server 2, only the updated data may be sent to the telephone as difference data, and the telephone directory database of the telephone may be updated. In this case, since the data sent to the telephone via the communication line 4 is only differential data, the bandwidth of the communication line 4 is not compressed. In addition, the update time of the telephone directory database that the telephone has is shortened. When matching telephone numbers, another database may be prepared and registered in advance, or may be registered in a telephone.

  Alternatively, each time a call is made, authentication may be performed every time and a telephone number may be acquired from the presence management server 2. At this time, the telephone number itself is not registered in the telephone directory database of the telephone. For this reason, for example, the information of the telephone number concerning the company president or officer is not known to a third party, and the risk of information leakage is reduced.

  Further, although the authentication device 18 is a card key type, other forms may be used. Further, for example, a user who uses a telephone may be identified by combining image data of fingerprint, palm print, iris authentication and a password. In this case, it is desirable that information such as a combination of fingerprint, palm print, iris authentication and password used for identifying the user is stored on the presence management server side.
