It may be. In response, the DM client 100 of the electronic device 100 transmits a device profile MO (DevProf MO) to the DM server 310 in step 519. If a device profile is included in DevInfo (see FIG. 3), step 517 and step 519 may be omitted.

Subsequently, the DM server 310 terminates the DM session, and transmits the Device Profile value obtained through the DM session to the SPB 320 in step 521.

The device profile / performance analyzer 322 of the SPB 320 analyzes the device profile in step 523 to find out whether the keyboard is supported, the screen size, the device type and function, the device capability, and the like. The portal site selector 324 of the SPB 320 then selects an appropriate registration site to provide to the device.

Subsequently, the SPB 320 provides, as connection information, an instruction for the device to hotlining to the registration site when a service connection request is made through the hotlining indication to the communication network 200 in step 527. At this time, the SPB 320 transmits the address (URI) of the registration portal (Subscription Portal) selected in step 525 together with the device ID to the communication network 200. At this time, the access information, that is, the corresponding hotlining information may be transferred from the SPB 320 to the ASN G / W (not shown) through the AAA server (not shown), or the ASN G / W (not shown) directly from the SPB 320. May be passed). Accordingly, the ASN G / W stores the hotlining information and reflects it in its operation. For example, when there is a service request or a connection request from the electronic device, the ASN G / W connects the electronic device to a stored hotlining site. In this case, the connected target is an address of a registration site selected according to the profile of the electronic device.

According to another embodiment, in step 529 the address (URI) of the selected registered portal site is notified to the DM server. The DM server 310 transmits the address (URI) of the registration portal site to the electronic device 100 through a DM session in step 531. Accordingly, the electronic device may access the received registration portal site. It will be appreciated by those skilled in the art that the transmission of the access information is optional and the present invention is not limited thereto.

Subsequently, when the electronic device 100 requests a registration or service in step 533, the electronic device 100, the communication network 200, and the SPB 320 perform a registration process or a service providing procedure in step 535. At this time, the user can register with the registration site through the interaction with the registration site.

After registering or performing a service process, the SPB 320 may release the hotlining setting for the corresponding electronic device in the AAA server of the communication network 200. As a result, the AAA server unsets Hotlining for ASN G / W. Alternatively, the SPB 320 releases the hotlining setting on the ASN G / W without going through the AAA server.
