For example, the message management server 180 may include a short message transmission system, and the terminal 130 may send a short message indicating that the new message has arrived and the address information (for example, URL information) of the message management server 180. The sender can check the message left by the sender by accessing the message management server 180 using the address information.

FIG. 2 is a diagram illustrating a configuration of an internet protocol multimedia subsystem according to the present invention. Although the detailed configuration of the IMS-1 140 is illustrated, this is for convenience of description and is illustrated in FIG. 1. The configuration of 160 can also be understood as the same concept.

The illustrated internet protocol multimedia subsystem 140 includes a call session control function (CSCF 140), a home subscriber server (HSS 144), and an application server (AS). 146)).

The CSCF 142 may perform basic functions for session initiation protocol (SIP) based multimedia session control such as subscriber registration, authentication, service triggering, routing, various call control, and address handling. . In particular, the CSCF 142 retains subscriber information and performs call processing with reference to it.

CSCF 140 may include Proxy-CSCF (P-CSCF 142a), Interogating-CSCF (I-CSCF 142b), and Serving-CSCF (S-CSCF 142c). )).

P-CSCF 142a is the first point at which originating terminal 110 or terminating terminal 130 connects to the Internet Protocol Multimedia Subsystem.

For example, when a registration request message (REGISTER) is transmitted from the terminal 110, the P-CSCF 142a forwards it to the I-CSCF 142b. The P-CSCF 142a stores the address of the S-CSCF 142c allocated by the I-CSCF 142b in the process of processing the registration request message, and then receives the session request message (INVITE) from the terminal 110. If so, it can be forwarded to the S-CSCF 142c.

The I-CSCF 142b serves as a contact point for incoming calls to connect to subscriber stations in the network and a contact point with terminals of other network subscribers roaming in the network. The I-CSCF 142b obtains an address of the S-CSCF available from the HSS 144 in the process of registering a user (hereinafter referred to as a subscriber) of the calling terminal 110 or the called terminal 130. With reference to this, the S-CSCF 142c which is in charge of actual registration may be allocated.

The S-CSCF 142c may register a subscriber with the HSS 144 when a registration request message is received from the I-CSCF 142b, and obtain a service profile of the subscriber from the HSS 144. The S-CSCF 142c checks the type of service to be provided to the calling terminal 110 or the called terminal 130 using the service profile, and performs triggering on the AS 146 that will support the identified service. Can be.

The HSS 144 is a subscriber's master database, which stores and manages profile information, authentication and location related data, and provides information required by the I-CSCF 142b or the S-CSCF 142c. In addition, HSS 144 may include the functionality of a Home Location Register (HLR).

AS 146 holds the actual service logic. That is, depending on the service logic that it has, the AS 146 may support a particular service.

Examples of services supported by the AS 146 include Voice over Internet Protocol (VoIP) and video services, Instant Message (IM) services, and various session-based multimedia services. When the 110 attempts to make a call connection to the called terminal 130, when the call connection is not established, the callee 110 accesses the message management server 180 connected to the wired Internet network 170, and the called party is already registered. It is possible to support a service for the sender to store the message in the message storage means of. At this time, examples of the message storing means include a blog, a personal website or a personal homepage based on ENUM.

On the other hand, although the Internet protocol multimedia subsystem is shown in FIG. 2 as including the P-CSCF 142a, the I-CSCF 142b, the S-CSCF 142c, the HSS 144, and the AS 146 one by one. The present invention is not intended to be limited to this, because it is intended to describe the basic configuration of the Internet protocol multimedia subsystem. Thus, the internet protocol multimedia subsystem may include a plurality of devices or servers shown in FIG. In addition, although not shown in FIG. 2, a known device or server such as a multimedia resource function (MRF) that handles call mixing and media mixing for a multiparty service may be further included in the Internet protocol multimedia subsystem 140. have.

A method of storing a sender's message based on an internet protocol multimedia subsystem according to the present invention based on the contents shown in FIGS. 1 and 2 will be described in detail with reference to FIG. 3.

First, when the caller attempts to make a voice call or a video call to the called party's called party 130 using the calling party terminal 110, the called party's terminal 130 is located in an area where the call is unavailable or the power is turned off. Or if the called party is on the phone with another person, the call is not connected.

In this case, the calling terminal 110 uses a service through the internet protocol multimedia subsystem to store a message for the called party. For this purpose, the calling terminal 110 uses the CSCF 140 in the internet protocol multimedia subsystem. Request subscriber registration (S310).

Upon receiving the request, the CSCF 140 accesses the home subscriber server 144 to request a user profile (S320), and the home subscriber server 144 provides the caller's user profile to the CSCF 140 according to the request. (S330). In this case, the user profile may include information necessary for providing a service to the calling terminal 110.

The CSCF 140 performs the message storage service according to the present invention with respect to the application server 146 based on the user profile (S340). Accordingly, the application server 146 performs the IP core network 150 and the IMS-. A request is made to store the sender's message to the message management server 180 connected to the wired Internet network 170 via 2 (160) (S350, S360). At this time, the application server 146 is based on the IP address or URL address information of the message management server 180 to store the message of the sender in response to the telephone number or device identification information of the called terminal 130. Attempt to connect to the message management server 180 to store the message.

Through this process, a communication channel for storing messages is formed between the calling terminal 110 and the message management server 180, and the message of the sender's message is provided by the message management server 180 through the communication channel thus formed. It is stored in the storage means (S370). The message stored at this time includes a video message, a voice message or a text message.

First, when a caller stores a message in a message storage means such as a personal homepage of a called party by using the calling terminal 110 and presses the end button of the calling terminal 110, the message management server 180 displays a new message. An event message indicating that the message has been stored is transmitted to the called terminal 130. The event message is transmitted to the called party terminal 130 via the wired internet network 170, the IMS-2 160, the IP core network 150, the IMS-1 140, and the mobile communication network 120. In addition, the event message is IP address or URL address information of the message management server 180 in which the sender's message is stored, sender information, message type (image message / voice message / text message) information, time at which the message is stored, and message size information. And the like.

At this time, when the called party checks the event message and presses the connection button of the called terminal 130, the called terminal 130 accesses the message management server 180 to check the message left by the caller.

To this end, the destination terminal 130 first accesses the CSCF 140 constituting the IMS-1 140 (S410). Then, the CSCF 140 accesses the home subscriber server 144 to request a user profile (S420), and the home subscriber server 144 provides the called user's user profile to the CSCF 140 according to the request ( S430). In this case, the user profile may include information necessary for providing a service to the called terminal 130.

The CSCF 140 performs the message checking service according to the present invention with respect to the application server 146 based on the user profile (S440). Accordingly, the application server 146 performs the IP core network 150 and the IMS-. Attempts to connect to the message management server 180 connected to the wired Internet network 170 via 2 (160) (S450, S460). At this time, the application server 146 is based on the IP address or URL address information of the message management server 180 that stores the sender's message in response to the telephone number or device identification information of the called terminal 130. Attempt to connect to the message management server 180 that stores the message.

Through this process, a communication channel for confirming a message is formed between the called party terminal 130 and the message management server 180, and the called party confirms the message stored by the caller through the formed communication channel (S470).

In FIG. 4, although the event message is received by the calling party terminal 130, connection to the message management server 180 is made by the caller's selection. However, the event message is automatically received and the calling terminal is automatically received. A communication channel for message confirmation may be formed between the 130 and the message management server 180.

On the other hand, in this embodiment, the called party uses the called terminal 130 to check the message stored in the message management server 180, to the same Internet protocol multimedia subsystem that the calling terminal 110 is connected to. Although the connection is demonstrated as an example, it is not necessarily limited to this. That is, depending on the geographic location of the calling terminal 110 and the called terminal 130, the same internet protocol multimedia subsystem may be connected, or different internet protocol multimedia subsystems may be connected.
