At this time, information on the capability of the service terminal defined in XML format is transmitted in the body of the SIP SUBSCRIBE message as shown in FIG. When the user agent 30 receives the SIP SUBSCRIBE message from the service terminal 20, the user agent 30 transmits the SIP response message (SIP 200 OK) accordingly to the service terminal 20 (S502). In addition, the user agent 30 transmits a SIP NOTIFY message to the service terminal 20 to inform the current status of the SIP SUBSCRIBE message (S504). The service terminal 20 receiving the SIP NOTIFY message transmits the SIP response message (SIP 200 OK) accordingly to the user agent 30 (S506). In this way, the preparation process of the service terminal 20 is completed.

Next, a user registration process (B) for the mobile multimedia service network 200 for a user entering the sensing area 1 will be described. When the user having the smart tag 12 enters into the sensing area 1 and is detected by the sensor 14 of the sensing device 10 associated with the user agent 30, the sensor 14 is a smart tag. Information about the user read from 12 is transmitted to the user agent 30 (S510). The information on the user at this time includes the user's SIP URI and the unique identifier of the smart tag 12. The user agent 30 registers a user in the mobile multimedia service network 200 by using the user information transmitted as described above. The user agent 30 transmits a SIP REGISTER message to the S-CSCF 40 in order to register a user in the mobile multimedia service network 200 (S512). Then, the S-CSCF 40 accesses the home subscriber server 50 and downloads a service profile for the corresponding user (S514). The S-CSCF 40 which has downloaded the service profile carries the service profile on the body of the SIP response message (SIP 200 OK) for the SIP REGISTER message and transmits the service profile to the user agent 101 (S516). At this time, the user agent 301 is a service terminal 20 for providing a continuous service by referring to the service profile received from the S-CSCF 40 to provide a continuous service to the user sensed by the sensor 14 Determine (S518). At this time, the selected service terminal 20 is selected based on the capability information of the service terminal 20 sent along with the body when the service terminal 20 subscribes via the SIP SUBSCRIBE message (A).

By utilizing the service profile for the user in the home subscriber server 50, it is possible to provide a continuous service to the user.

Next, a process of canceling a user registration for the mobile multimedia service network 200 for a user who has entered the sensing area 1 will be described. Here, a case in which the user who received the service provided as described above is separated from the sensing area 1 is shown.

First, when the user detects the exit from the sensing area 1 by the sensor 14 of the sensing device 10, the sensor 14 transmits the user information according to the exit event to the user agent 30 (S530). At this time, the SIP URI of the user and the unique identifier of the smart tag 12 is transmitted together as in the case of entrance detection (S510). The user agent 30 receiving the user information according to the detection from the sensing area 1 from the sensor 14 transmits a SIP NOTIFY message to the corresponding service terminal 20 and requests the state information of the terminal (S532). . The service terminal 20 receiving the SIP NOTIFY message stops the service and transmits the status information of the service through the SIP response message (SIP 200 OK) accordingly (S534). At this time, the SIP response message includes the final usage information of the service received by the user and transmits it. Then, the user agent 30 updates the information on the service terminal 20 based on the state information included in the SIP response message (S536). That is, the status information for each service stored in the user agent 30 is updated in the tag format for each service of the mobile service configuration tag b 'shown in FIG. In addition, by deleting the SIP URI information for the user who used the service included in the status information, and returns to the state to support the next user (S536).

Then, the user agent 30 transmits the SIP REGISTER message to the S-CSCF 40 (S538) to perform the termination of registration for the user from the mobile multimedia service network 200. At this time, the service profile reflecting the updated information about the service received by the user is transmitted on the body of the SIP REGISTER message. Upon receiving the SIP REGISTER message, the S-CSCF 40 stores the service profile information reflecting the updated information in the home subscriber server 50 (S540). Then, the user agent 30 transmits a SIP response message (SIP 200 OK) according to the SIP REGISTER message (S542). In this way, the service profile update operation for the user who has entered the sensing area 1 is completed.

In addition, the function of the agent according to the method of the present invention as described above may be stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) recording a program implemented as a program.
