Here, the directory information previously stored in the second terminal device 200 may include at least one of previously stored address book information, phone number information, business card information, schedule information, anniversary information, and email information.

In this case, when the first terminal device 100 describes the process of connecting to the second terminal device 200 through the PS communication network 1, a request for providing predetermined directory information of the second terminal device 200 is input from the user. Accordingly, the first terminal device 100 requests a SIP session setup by providing a SIP Invite message to another terminal device (for example, the second terminal device 200) (S20). Accordingly, the second terminal device 200 receiving the SIP Invite message provides the SIP 200 ok message to the first terminal device 100 in response to the SIP Invite message (S30). When the SIP 200 ok message is received from the second terminal device 200 and the SIP session setting is accepted, the first terminal device 100 returns a SIP Ack message to the second terminal device 200 (S40). The SIP session setting between the terminal device 100 and the second terminal device 200 may be completed.

As such, when the first terminal device 100 is connected to the second terminal device 200 through the PS communication network 1, the first terminal device 100 is the second terminal device 200 as directory information (for example, a user). C) provides a request for the provision of telephone number information (S50). The request for providing directory information arrives at the destination exchange 3 of the second terminal device 200 via the path of the SIP session, that is, the source exchange 2 of the first terminal device 100 side of the PS communication network 1 ( S50).

The destination exchange 3 requests the service user DB server 300 to confirm whether the second terminal device 200 is a service subscriber when a request for providing directory information from the first terminal device 100 is received ( S60). Accordingly, when the service user DB server 300 requests confirmation from the destination exchange 3 whether the second terminal device 200 is a service subscriber, the service user DB server 300 subscribes to at least one terminal device subscribed to the directory service. On the basis of the information, it is determined whether or not the service subscriber of the second terminal device 200 (S70). Accordingly, when the service user DB server 300 provides a confirmation result indicating that the second terminal device 200 is a service subscriber to the destination exchange 3 (S80), the destination exchange 3 is connected to the second terminal device 200. ) Recognizes that the service subscriber is a service subscriber, and provides a request for providing directory information from the first terminal device 100 received in step S50 to the second terminal device 200 (S90).

As such, upon receiving the request for providing directory information through the SIP session of the PS communication network 1, the second terminal device 200 confirms the request reception by providing a SIP 200 ok message to the first terminal device 100 (S100). ).

Then, the second terminal device 200 responds to the request for providing directory information (eg, phone number information of the user C) based on the authority information for the terminal device that allows reading in correspondence with each of the at least one directory information. Check the authority of the first terminal device 200 for the directory information (for example, the phone number information of the user C) (S110).

As a result of checking the authority, if it is determined that the first terminal apparatus 100 has authority to the directory information (eg, telephone number information of the user C) requested from the first terminal apparatus 100, the second terminal apparatus 200 is determined. The directory information (eg, phone number information of the user C) is provided to the first terminal device 100 through the SIP session of the PS communication network 1 (S120). On the other hand, as a result of checking the authority, if it is determined that the first terminal device 100 does not have authority to the directory information (eg, phone number information of the user C) requested from the first terminal device 100, the second terminal device ( 200 may notify the first terminal device 100 of the rejection of the inquiry corresponding to the request for providing directory information from the first terminal device 100 by providing a SIP 401 Not Authorized message to the first terminal device 100 ( S130).

As described above, according to the method for providing a directory service according to the present invention, when a user of the first terminal device 100 wants to receive directory information of the second terminal device 200 which is another terminal device, the second terminal device The first terminal device 100 directly accesses the desired second terminal device 200 through the PS communication network 1 without receiving a separate management server for managing the directory information of the 200 and receives the directory information to be provided. The second terminal device 200 may directly request the second terminal device 200, and the second terminal device 200 may provide the requested directory information to the first terminal device 100.

Thus, according to the method for providing a directory service according to the present invention, a user who wants to know directory information of another terminal device does not have to do unnecessary act of asking the user of the other terminal device to the corresponding directory information, and the directory of the terminal device. Rather than having a separate management server for managing information, a user can directly access another terminal device through a PS communication network using his terminal device to obtain directory information that he / she wants to know.
