Will expand. Attention has been given to attempting international standardization as an infrastructure for providing IP multimedia services.

IMS improves the price competitiveness of services by using general Internet-based technology, and enables easy interworking with various 3rd party applications based on efficient session management function, and enables expansion of business area through global interworking between services. .

In order to provide multimedia services between portable Internet terminals or users, an application layer signaling / control protocol called SIP is used.

SIP corresponds to H.323 of ITU-T, a signaling protocol, and is a protocol developed and proposed by the IETF for establishing and controlling sessions between portable Internet terminals or users. This enables call setup of various services as well as existing VoIP services.

SIP is a very simple text-based application layer control protocol that allows one or more participants to create, modify and terminate sessions together. These sessions include teleconferencing, telephone, meetings, instant messaging (SMS), etc., using the Internet. It also works independently of the underlying packet protocols (TCP, UDP, ATM, X.25, etc.).

SIP was designed after text-based SMTP and HTTP. SIP is based on a client / server architecture where the client initiates a call and the server responds to the call. By following the existing text-based Internet standards, parsing, extensions, and debugging are very easy.

The portable Internet referred to in the present invention will be described below as being a portable Internet based on IMS. However, this is only one example and it is obvious that the present invention can be applied based on various environments while maintaining the gist of the present invention.

Referring to FIG. 1, a mobile Internet user (hereinafter referred to as UE) 100 provided with a service according to the present invention uses a WiBro messenger 101 in a mobile Internet backbone network 103 constructed based on IMS. The mobile internet portal 102 is connected to and provided with various SIP-based multimedia services 104 which are guaranteed quality.

The UE 100 is provided in a form of providing a screen such as a PDA, a dedicated terminal or a laptop, and the UE connects to the IMS-based portable Internet network 103 after installing the WiBro messenger 101. When the network is connected and authenticated, IMS service registration and service authentication are executed. At this time, the service and the personalized service configuration environment applied for each individual are downloaded to the terminal and displayed on the WiBro messenger.

WiBro messenger uses buddy list (e.g., buddy list location and status information) and personalization environment (e.g. access area weather or geographic location) based on IMS based presence / location 105 information. Will be constructed. Based on these components, a user can launch a service to his or her list or use other supplementary services.

The services configured in the WiBro messenger are IMS-based services 104 and 105, and are used in connection with each application service under the control of an IMS service through a SIP message by the user's service initiation (clicking the icon).

4 illustrates an example of a flow of a method of accessing a portable Internet portal service and a method of starting an application service between portable Internet terminals according to the present invention. 4 is divided into two steps, a connection procedure to a WiBro portal of a portable Internet, and an initiation procedure of a SIP application service.

First, the method for accessing the portable Internet portal service according to the present invention is executed as follows. This process corresponds to the section 400 marked WiBro portal access procedure.

A user using the WiBro terminal 410 that provides a mobile Internet may use a SIP register message including parameters such as a user identifier and a home domain name to provide a connection service according to the present invention. Control function 420) (step 1). The P-CSCF 420 is a server that provides a proxy role for the WiBro terminal 410.

The P-CSCF 420 obtains the address of the Interrogating-Call State Control Function (I-CSCF) server 430 of the home domain name from the received Uniform Resource Identifier (URI) of the SIP, and then the P-CSCF 420 ), The register message is added to the I-CSCF 430 by adding an address, an identifier, and the like (step 2).

The I-CSCF 430 determines whether a user is registered with the home subscriber server (HSS) authentication server 450, which is a user registration server, through a user-authentication request (UAR) parameter message with reference to the received register message. Inquire, whether the user can roam the current network (step 3).

After receiving the UAR message, the HSS authentication server 450 determines the result of the I-CSCF through the UAA (User-Authentication Answer) message, depending on whether the user is already registered and whether it is not registered but roams in the visiting network. Answer 430 (step 4). At this time, if the subscriber is not registered and roaming is possible, a list of a serving-call state control function (S-CSCF) server 440 (hereinafter referred to as S-CSCF) that is a user registration server capable of providing a registration function for a user. Is added to the message and sent to the I-CSCF 430.

The I-CSCF 430 receives the UAA message, selects the appropriate user registration server S-CSCF 440 by referring to the received information included in the message, and sends the SIP to the address sent by the user in step 1. Send a register message (step 5).

The S-CSCF 440 sends a multimedia authentication request (MAR) parameter message to the HSS authentication server 450 and requests an authentication vector for the user (step 6).

The HSS authentication server 450 generates a corresponding authentication vector and transmits it to the S-CSCF 440 through a multimedia authentication answer (MAA) message (step 7).

After the S-CSCF 440 downloads the user profile from the HSS-authentication server 450, the S-CSCF 440 serves the user according to the initial and following conditions of the FC (Filter Criteria). Select the WiBro messenger configuration system 460 (server) with the appropriate service logic to be used, and use the WiBro message configuration system 460 to register user information, i.e., the information required for personalized screen composition (user rights, type of service to provide, service). Bandwidth or Quality Assurance (QoS) according to the provision) are sent (step 8).

After the WiBro messenger configuration system 460 normally receives the WiBro messenger component request message from the S-CSCF 440, the WiBro messenger configuration system 460 constructs a menu list necessary for information required for personalized screen configuration. When the menu list is configured, the user registration information response message is sent to the S-CSCF 440 (step 9) to download the personalized screen configuration of the user, and the user's mobile Internet portal service control procedure is performed.

The S-CSCF 440 transmits a 200 OK message to the I-CSCF 430 (step 10). This is in response to sending the register message of step 5, meaning that the user is registered with the WiBro messenger configuration system 460.

The I-CSCF 430 sends a 200 OK message to the P-CSCF 420 in response to sending the register message in step 2, and then revokes all registration information (step 11).

The P-CSCF 420 stores the access information of the home network and transmits a 200 OK message to the terminal 410 in response to the register message in step 1 (step 12). Through this response message, the terminal 410 can know the WiBro messenger configuration system to which the WiBro messenger screen configuration information to be executed in its own terminal is requested, and can immediately access the WiBro messenger configuration system without a separate registration procedure.

Upon receiving the 200 OK message, the terminal 410 transmits a personalized WiBro messenger screen composition request message to the WiBro messenger configuration system 460 (step 13).

The WiBro messenger configuration system 460 receiving the request message compares the user information received from the S-CSCF 440 at the time of user registration in step 8 with the identifier of the user who sent the request message in step 13 to confirm that the user is a registered user. Thereafter, information about the WiBro messenger configuration screen is given to the UE, which is the portable Internet terminal 410 (step 14).

The terminal 410 includes a component that displays a screen as shown in FIG. 3 and provides a service for a user's input. The operation thereof has already been described.

Secondly, according to the present invention, a method for starting an application service between portable Internet terminals is as follows. This process corresponds to the part described as the service initiation procedure at 470. In addition, the reference numbers of the system used in the reference numeral 400 are used the same.

As shown in the reference numeral 400, the mobile internet portal registration is completed and the terminal 410, which has downloaded the information on the WiBro messenger configuration screen and configured the messenger screen according to the information, uses the WiBro messenger displayed on the screen of the terminal 410 to perform the service. A SIP Invite message for initiation is transmitted to the P-CSCF 420. Through this, a session establishment procedure for data transmission between terminals starts (step 1).

The P-CSCF 420 receiving the SIP invite message transmits the invite message to the S-CSCF 440 having the registration information during the registration procedure (step 2).

The S-CSCF 440 transmits the invite message to the counterpart terminal 480 registered to the S-CSCF 440 (step 3). The terminal of reference numeral 410 is now the calling terminal, and the terminal of reference numeral 480 is the receiving terminal.

After the resource allocation is completed between the calling terminal 410 and the receiving terminal 480 through a Session Description Protocol (SDP) message exchange, the receiving terminal 480 transmits a 200 OK message to the S-CSCF 440. To respond to the invitee in step 3 (step 4).

The S-CSCF 440 transmits a 200 OK message to the P-CSCF 420 serving as a proxy server of the calling terminal 410 in response to the invite of step 2 (step 5).

Receiving the 200 OK message in response to step 1, the calling terminal 410 completes the session setup preparation with the receiving terminal 480 (step 6).

After a Real-time Transport Protocol (RTP) session is established between the originating terminal 410 and the receiving terminal 470 for a transmission service, data transmission is performed (step 7).
