1 is a block diagram schematically illustrating an entire system for providing a PBA based service by an IMS based presence system according to an exemplary embodiment of the present invention.

As shown in FIG. 1, the entire system includes a terminal 10, a presence system 100, and an address book management system 50.

In the present embodiment, an IMS-based communication network will be described as an example, but in addition to the IMS network, all communication networks interoperable with the presence system 100 such as a wide-band code division multiple access (WCDMA) network may be equally applied. The following description will become more apparent.

The IMS network is a communication network based on a communication network standard proposed by the 3rd generation partnership project (3GPP), and provides an IP-based communication service, and mainly uses a SIP signaling protocol. Since the IMS network will be apparent to those skilled in the art, a detailed description thereof will be omitted.

The terminal 10 is a communication device capable of performing a communication such as a call or an Internet connection through an IMS network. Personal Digital Assistant (PDA), Portable Multimedia Player (PMP) and the like.

The terminal 10 according to a preferred embodiment of the present invention uses a session initiation protocol (SIP) for data communication with an IMS network, wherein SIP is a signaling protocol, and a SIP-based service is a signaling traffic for establishing a session. And data traffic, which is the transmission and reception of data according to the actual media.

The watcher 12 and the terminal address book application 1 14-1 shown in the drawing may be implemented in software in the terminal 10. The watcher 12 functions to request and acquire the presence information on whether to log in to another terminal to communicate with the presence system 100. That is, the terminal 10 uses the watcher 12 to perform additional services such as IM (Instant Messaging) and PTA (Push To All) as well as communication with other terminals, such as telephone calls and message transmission. Presence information about the terminal can be obtained.

The IM service combines wired and wireless networks to send text and mail in real time. Similar to services such as fax, short message service, and e-mail, but different in terms of real-time communication, not only mobile phones, but also text-based communication. It also combines real-time technology that can always be received, unlike a landline phone or personal computer (PC), such as chat group management, contact online confirmation and invitation, presence and real-time chat. The PTA service is a multi-party communication tool service, which includes a multi-party video call / messenger / file sending function.

 The terminal address book application 14-1 performs a function of registering the PBA information stored in the terminal 10 with the address book server 52. Registering the PBA information in the address book server 52 such as a personal information management system (PIMS) using the terminal 10 is a technique that is still used, and thus the detailed description thereof will be omitted.

Address book application 2 (14-2), address book application 3 (14-3) to address book application n (14-n) shown in the figure are applications for registering PBA information to address book server 52 in a wired or other environment. For example, the application may be provided at a web site of a telecommunication company. That is, the user may access the specific site providing the address book application and register the PBA information of the terminal 10 in the address book server 52. Typically, the terminal address book application uses an application protocol such as HTTP or XML, and a communication protocol based on TCP / IP.

The presence system 100 may include a presence server 110 and a DB 130 (hereinafter, referred to as a presence DB). The presence server 110 obtains the presence information from the subscribed terminal 10, that is, the presence sources 30 providing the presence information. Although the terminal 10 and the presence source 30 are illustrated as separate devices in the drawing, since the terminal 10 also provides the presence information to the presence system 100, the concept is included in the presence source 30. . The PDB 130 stores presence information about the subscribed terminals 10. As described above, the presence information may include information about whether the terminal 10 is logged in to the IMS network, schedule information, and logical or physical state information of the subscriber such as "busy." Preferably, the PDB 130 stores presence information based on the presence information data format (PDF) standard.

In addition, the presence server 110 may include functions of a resource list server (RLS) and a GLMS group list management server (RLS). When the subscriber station requests status information on a specific list such as a group through a group ID representing a group list owned by the subscriber station, the RLS checks the information of the buddy list registered in the group ID and the subscriber terminal. Notify Due to RLS, the subscriber station does not need to request information for group members in order to collect information on a group, thereby efficiently collecting information. GLMS is a system that manages and controls the policy for providing group information and individual status information for each subscriber.

According to a preferred embodiment of the present invention, the terminal 10 does not individually manage the service buddy list (Publish) by sending their buddy list to the presence server 110 individually, The presence system 100 may receive the corresponding PBA information from the address book management system 50 that already has the PBA information managed by the subscriber in a wired or wireless environment and use it as buddy list information. The presence system 100 provides the corresponding PBA information to the terminal 10, and the terminal 10 user who received the PBA information receives the PBA information as a service buddy list through the addition or deletion of all PBA information as it is. System 100 can be managed. By doing so, the user of the terminal 10 can register or manage the buddy list more efficiently and conveniently in a service that needs to provide a service using a buddy list such as an IM (Instant Messaging) service.

In this process, the presence system 100 is interworked with the address book management system 50. The address book management system 50 includes an address book server 52 and a phone book DB server 54. The presence system 100 may obtain the PBA information of the subscribed terminal 10 from the phonebook DB server 54 of the address book management system 50 and use it when providing a service to the terminal 10. For example, when the terminal 10 uses Instant Messaging (IM) service, the presence system 100 obtains PBA information corresponding to the terminal 10 from the phonebook DB server 54, and the corresponding PBA information. Presence information of the corresponding terminal 10 may be provided to other terminals corresponding to the terminal 10, and the presence information of the other terminal may be provided to the terminal 10 requesting service.

The communication between the presence system 100 and the address book management system 50 may use a SIP or Ut interface, and in general, an Extensible Markup Language Configuration Access Protocol (XCAP) is used to process the Ut interface. XCAP is a protocol mainly used for users to store, modify, and delete information related to themselves through a communication network such as the Internet. Typically, XCAP can be used when the Instant Messaging and Presence Protocol (IMPP) system sends its friend list data to the server.

According to another preferred embodiment of the present invention, the DB (hereinafter, phonebook DB) of the PDB 130 of the presence system 100 and the phonebook DB server 54 may be integrated. That is, one integrated DB may be shared by the presence server 110 and the address book server 52. Hereinafter, for convenience of description, the PDB 130 and the phonebook DB of the phonebook DB server 54 of the presence system 100 are separately present as shown in the drawing, and will be described with an example of interworking with each other.

Can be stored according to the format.

If there is a change in the phone book address book information (PBA information) in the terminal 10 in the future, the terminal 10 may be connected to the address book server 52 to change the PBA information stored in the phone book DB. In this case, the phonebook DB server 54 may transmit the PBA information about the changed contents to the presence system 100, and the presence system 100 that receives the changed PBA information may change the corresponding service buddy list. .

According to another preferred embodiment of the present invention, the terminal 10 may change the PBA information by using the presence system 100. That is, when the changed PBA information is transmitted to the presence system 100, the presence system 100 changes the corresponding service buddy list and transmits the related information to the phonebook DB server 54.

That is, the service buddy list in the PDB 130 of the presence system 100 and the PBA information of the phonebook DB server may be interlocked with each other so that sync is synchronized. Of course, the interworking of the PBA information between the two systems is more preferably implemented to be performed according to the control command transmitted from the terminal 10.

Hereinafter will be described the configuration of the presence server 110 according to an embodiment of the present invention.

Referring to FIG. 2, the presence server 110 includes a communication unit 210, a presence information acquisition unit 220, a PDB management unit 230, a buddy information processing unit 240, and a control unit 250.

The communication unit 210 is a communication means for communicating with the terminal 10, the phone book DB server 54 and the address book server 52.

The presence information acquisition unit 220 performs a function of acquiring the presence information from the presence sources 30. The presence information acquisition unit 220 may communicate with the terminal 10 using SIP or XCAP.

The PDB management unit 230 stores functions such as the presence information about the subscriber terminal and information on the corresponding service buddy list in the PDB 130 or extracts from the PDB 130. Perform.

The buddy information processing unit 240 manages a service buddy list according to each service for subscription terminals. For example, when an arbitrary terminal is subscribed to an IM service and a PTA service, the buddy information processing unit 240 manages a service buddy list according to the IM service and a service list different from the PTA. When the service buddy list corresponding to the subscribed terminal is not set, the buddy information processing unit 240 establishes a service buddy list according to the PBA information in association with the phonebook DB server 54. In addition, the corresponding service buddy list is changed in response to the request for changing the service buddy list from the subscribing terminal, and the corresponding related information is transmitted to the phonebook DB server 54 (of course, provided to the address book server 52, and the address book server 52). ) May control the phonebook DB server 54 to update the PBA information.

The control unit 250 is connected to the address book management system 50, the presence server 110 to set the service buddy list according to the PBA information of the terminal 10, so that when using the service, the set service buddy list can be used Control the communication unit 210, the presence information acquisition unit 220, the PDB management unit 230 and the buddy information processing unit 240.

Hereinafter, when the IM service is provided among the additional services provided in the IMS network, the process of providing the PBA based service by the presence system 100 will be described.
