Description

{A METHOD TO TRANSMIT SELECTIVELY PRESENCE INFORMATION IN THE PRESENCE SERVICE}

The present invention relates to a presence service in a mobile communication network, and more particularly, to a method of selectively delivering presence information when providing a presence service in a mobile communication network.

The presence service refers to a service that provides a user with presence information such as checking a user's location information, checking a user's communication status, that is, checking a user's online or offline status, checking a media type, and the like.

Recently, instant messenger (Instant Messenger), which is used as an online communication means among Internet users, is a type of service that sends a message to a user who is online by using the presence information.

The presence service currently being serviced on the wire has no function of selecting and delivering a counterpart for each presence information, and the entire subscriber's presence information is delivered to the selected counterpart. Therefore, the presence service subscriber cannot provide different presence information according to the counterpart, and all have to provide the same presence information.

SUMMARY OF THE INVENTION An object of the present invention is to solve the fact that in the presence service serviced on a conventional wireline, when the subscriber's own presence information is transmitted to the counterpart, the counterpart cannot be selected and transmitted for each presence information, which is suitable for a mobile communication network. When providing the presence information to the counterpart when providing the presence service, it provides a method for selectively delivering only the set presence information for each subscriber or group.

1, there is shown a schematic diagram of a SIP-based synchronous network for presence service according to the present invention.

Referring to the components of the SIP-based synchronous network of FIG. 1, the presence information message indicating the subscriber's presence information and the subscriber's status with respect to the presence information is transmitted to the terminal 10 of the presence service subscriber station. Through the BSC 22 (Base Station Controller), it is sent to the PDSN 24 (Packet Data Serving Node). The presence information and status information message transmitted to the PDSN is transmitted to the presence server 40 for providing the presence service through the SIP server 30. The subscriber notifies the presence server 40 of his status through the above system, and inquires of the status of the subscribers in his buddy list.

When requesting the presence service of the other subscriber, the presence information and status information message of the subscriber managed by the presence server 40 is transmitted through the SIP server 30, the PDSN 24, and the BSC 22. It is delivered to the other subscriber through 20).

The PDSN is a core component of the DCN (Data Core Network), a system that provides packet data service to mobile subscribers. The SIP (Session Initiation Protocol) is a protocol for controlling a general telephone service call to connect a telephone by using an Internet Protocol (IP) network and is a relatively simple text-based protocol. SIP is used as a means of initiating sessions between users and provides information for checking the user's connection and the status of the terminal using the registration server.

2 is a schematic diagram of a SIP-based asynchronous network for presence service according to the present invention.

Referring to the configuration of the SIP-based asynchronous network of FIG. 2, the presence information message indicating the subscriber's presence information and the subscriber's status with respect to the presence information is transmitted to the terminal 10 of the presence service subscriber. Through the RNC 25 (Radio Network Controller), the SGSN 26 (Serving GPRS Support Node) and the GGSN 27 (Gateway GPRS Support Node), the SIP server 30 and the presence server 40 are transmitted. do. The subscriber notifies the presence server 40 of his status through the above system, and inquires of the status of the subscribers in his buddy list.

The RNC 25 is a component of a radio access network (RAN) that controls a base station of an asynchronous IMT-2000 system, and functions for radio resource management of an IMT-2000 system and a base station in a wireless subscriber network. It manages and manages the interface between RNC and other network elements.

The SGSN 26 is a node in charge of data packet transmission with a mobile station in a service area, and has functions such as packet routing and transmission, mobility management, logical link management, authentication, and charging, and the SGSN's location register is assigned to the SGSN. Location information (such as a cell or visitor location register) of a registered General Packet Radio Service (GPRS) user, a user profile (international mobile station identification number: IMSI), and the like. The GGSN 27 is a node in charge of the connection function between the backbone network and the outer packet data network.

3 is a schematic configuration diagram of a synchronous network using an SMS network for presence service according to the present invention. FIG. 3 is the same as the network of FIG. 1 except that the SMS network is not used. Do.

The presence information message indicating the subscriber's presence information and the subscriber's status with respect to the presence information is transmitted to the terminal 10 of the presence service subscriber via the base station 20 through the BSC 22 (Base Station Controller). (28) (Mobile Switching Center). The message sent to the MSC is transmitted to the SMSC 29 (Short Message Service Center) and then to the presence server 40. The subscriber notifies the presence server 40 of his status through the above system, and inquires of the status of the subscribers in his buddy list.

In case of requesting the presence service of the other subscriber, the presence information and status information message of the subscriber managed by the presence server 40 is transmitted through the SMSC 29, the MSC 28, and the BSC 22. ) Is delivered to the other subscriber.

Although not described in detail herein, the presence service through an asynchronous network using an SMS network may be possible.

Referring to FIG. 4, a flowchart of a method for selectively delivering presence information of a presence service according to an embodiment of the present invention is disclosed.

In order to selectively deliver the subscriber's presence information in the presence service, the presence information is first configured in the subscriber's terminal (110). The presence information configured in the subscriber terminal may be the presence information basically provided by the presence service provider, or may be the presence information dynamically configured by the subscriber himself.

After the presence information is configured as described above, a transmitter selection request message for selecting and selecting a forwarder for each presence information configured in the subscriber terminal is input to the terminal (120). On the other hand, when selecting a forwarder for each presence information, the forwarder can be selected by individual or group.

Then, the forwarder selection request message input to the terminal is transmitted to the presence server for providing the presence service to the subscriber through the mobile communication network (130). The mobile communication network may be a SIP-based synchronous network, a SIP-based asynchronous network, a synchronous network using an SMS network, and the asynchronous network using an SMS network.

The forwarder selection message transmitted to the presence server is input to a forwarder information database for managing information about the forwarder (140). The forwarder information database of the presence server manages and controls presence information items, status information indicating the current state of subscribers, and data for individual or group forwarders for each presence information.

The presence information transmitters of the presence service request the subscriber's presence information in order to inquire the subscriber's presence information (150).

When the forwarder requests the subscriber's presence information, the subscriber's presence information request message is transmitted to the presence server (160).

When the presence server receives the presence information request message, only the presence information set for the forwarder who requested the presence information of the subscriber is transmitted to the terminal of the forwarder (170).

5a to 5f schematically show information displayed on the subscriber and the terminal of the forwarder, according to an implementation of the method according to the invention.

FIG. 5A illustrates six kinds of presence information that a subscriber of the presence service has already configured (for example, my weather, people to talk to today, people to meet, places to go to, my location and friends to say) ) Screen of the subscriber station. Such presence information may be dynamically configured by the subscriber of the presence service, or may be a menu basically provided by the presence service provider.

5B and 5C are screens of a subscriber station displayed to allow a subscriber to select a counterpart for each preconfigured presence information. 5B is a screen displayed to select a counterpart from a presence information item, and FIG. 5C is a screen displayed to select a counterpart from status information indicating a current state of a subscriber's presence information item. As shown in FIG. 5B and FIG. 5C, when a subscriber selects a counterpart for each presence information, the subscriber may select from the presence information item and may also select from the presence state information. In addition, when the counterpart is selected, the counterpart to which the presence information is to be delivered may be selected from a stored counterpart list, and the counterpart may be selected as an individual or a group.

5D to 5F are screens of a terminal of a transmitter to which different pieces of information of a subscriber's presence information are delivered. The presence server configures and transmits the presence information differently according to the subscriber's presence information and the sender. As shown in FIG. 5D to FIG. 5F, the forwarders see different presence information among the presence information of the subscriber.

What has been described above is merely an exemplary embodiment of the selective delivery method of presence information according to the present invention, and the present invention is not limited to the above-described embodiment, and as claimed in the following claims, the present invention Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.

As described above, according to the selective delivery method of the presence information according to the present invention, when providing a presence service suitable for a wireless network, a presence service subscriber can select and deliver a desired counterpart for each presence information. . Therefore, since the presence information can be selected and sent according to the counterpart, the subscriber can send the desired presence information only to the desired counterpart, and the counterpart has an advantage of not having to receive unnecessary presence information.
