BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caller display method, and more particularly, to a communication terminal and a caller display method of a communication terminal for outputting media information designated by a caller to a receiver's terminal when a call is set up in an IP-based communication service.

Almost all fixed and mobile networks will evolve based on Internet technology, and in particular, services combining several communication types and modes will lead the direction of future networks. That is, although voice itself is important, it will be only one part of the overall communication structure.

Session Initiation Protocol (SIP) as defined in the Internet Engineering Task Force (IETF) specification RFC 3261 provides an emerging standard for setting up multimedia sessions on the Internet. Its basic capability is the setup modification and teardown of any communication session, and hence the signaling protocol.

The SIP is used to establish, modify, and terminate sessions, provide personal mobility, and mean that a consumer can reach the network through a single address regardless of its current access point.

That is, personal mobility is provided by allowing a user to dynamically register with a network with a communication address, i.e., a SIP Uniform Resource Indicator (URI). Sessions are typically multiple real-time transport protocol (RTP) streams exchanged.

Typically, a session is a combination of speech, audio, and video streams, but may include a common application.

The SIP also uses an address format common to Internet mail, ie "user @ domain". The domain part is used to find out the exact domain for the consumer and the user part is used to distinguish between individual consumers in the domain.

For example, a SIP includes a request and response message that includes a header field, a recipient address, a sender address, and the like that define where the request is sent next.

The SIP may also include a portion of the payload for transmitting service specific information or subscriber.

Currently, the Third Generation Partnership Project (3GPP) details IMS in its description TS 23.228 as an access independent subsystem that can be used for connection with other networks. IMS uses the SIP for session initiation.

IP Multimedia Subsystems (IMS) is a core network technology in the ALL-IP concept that integrates wired and wireless environments. Mobile phone users can use one-to-many real-time group calls as well as two-way mobile gaming and instant messaging in an integrated mobile communication environment. It is a technology that enables users to enjoy IM) service on a mobile phone in real time.

In the future, the IMS network technology using SIP, that is, a wired / wireless integrated multimedia communication environment, enables free multimedia communication unlike the present time, and in particular, the caller designates the caller during the session setup process as the caller attempts to call the receiver. A service that allows media information to be displayed on the receiver's terminal is likely to be widely used, attracting the interest of many users.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing a communication system according to an embodiment of the present invention.

Referring to FIG. 1, a communication system according to an exemplary embodiment of the present invention may include an IP (eg, a public land mobile network (PLMN) 12, a public switched telephone network (PSTN) 18, etc.) connected through a gateway 12, 16. It is based on the Internet Protocol (10) network 10, and comprises an IMS (IP Multimedia Subsystems) server 28 for the service of the present invention.

As a communication terminal applied to the present invention, a communication service is performed based on an IP network 10 such as a cellular phone 20, a wired terminal 22, an IP terminal 24, a PDA 26, a personal computer 27, and the like. It includes a variety of wired and wireless terminals, the communication terminals should have a function to output the media information, and must be equipped with a SIP client function to enable the call setup through the IMS server (28).

The IMS server 28 may perform call setup of various services as well as an IMS service between terminals using a Session Initiation Protocol (SIP) message.

The SIP message is a peer-to-peer signaling protocol, which identifies a client using an e-mail form and provides mobility of the client. That is, it supports the client using the same SIP address but with the mobility of registering, modifying, deleting, and retrieving locations from terminals or computers in different places, and fork function, session connection function, and request message of other request messages. It is a protocol that operates independently of the lower transport protocols (TCP, UPD, ATM, X.25) and performs the function of rejecting or suspending a session in use.

The IMS server 28 receives the SIP message as the call is attempted from the communication terminal, and includes the SIP information transmitted by the caller who attempted the call to display on the receiving terminal and the call-id information corresponding to the media information. Send the message to the receiving terminal.

Herein, the communication terminal according to the present invention may select media information to be transmitted to the receiving terminal by using the caller's terminal when making a call request.

In addition, the IMS server 28 provides a function of transmitting and receiving messages through the RTP / RTCP (Real-time Transport Protocol / Real-time Transport Control Protocol) layer, the lower TCP / UDP layer, and the IP layer. Dynamic transmission and playback for services is enabled, and the RTP / RTCP protocol improves the quality of real-time multimedia services through jitter, transmission loss and dynamic resource utilization.

Meanwhile, although a general SIP message is transmitted through a User Datagram Protocol (UDP) protocol, the media information may be transmitted through a Transmission Control Protocol (TCP) protocol instead of a UDP protocol, and the IMS server 28 is output to a receiving terminal. The size of the media information is measured and billing can be performed accordingly.

Therefore, when the caller selects specific media information by operating his terminal when the call is requested, the caller's communication terminal transmits a SIP message including the media information and call-id to the receiving terminal, wherein the receiving terminal The media information is displayed on the screen window or output through a speaker until the receiver accepts the call start.

2 is a diagram illustrating a mobile communication terminal among communication terminals according to an exemplary embodiment of the present invention.

2, a mobile communication terminal 30 according to an embodiment of the present invention, the call means 31 for performing a call request and acceptance, a media information database 32 for storing media information, and the media information. And a message processor 33 for processing a SIP message including a call-id corresponding to the media information, and a playback unit 37 for displaying the media information.

Here, the mobile communication terminal 30 may be used as a calling terminal and a receiving terminal and is referred to as a communication terminal for convenience of description. In addition, the caller's mobile communication terminal will be referred to as a caller terminal and the receiver's mobile communication terminal will be referred to as a receiver terminal.

In addition, the communication terminal may be a transmission-only terminal having only a function of transmitting media information and not receiving or a reception-only terminal having only a function of receiving media information and not transmitting media information.

The call means 31 may request to start a call or accept the requested call. For example, when a caller makes a call using the call means of the caller terminal, the caller of the caller terminal notifies the caller of the caller through a bell or a buzzer.

At this time, if the receiver accepts such a request, the call means of the receiving terminal sends an acceptance message to the call means of the calling terminal to open a call channel, enabling a call between the caller and the receiver.

The media information database 32 may store at least one or more media information. When the caller selects any one of the plurality of media information at the time of a call attempt, the message processing unit 33 may select the selected media information and the information. A SIP message including call-id information corresponding to media information is generated.

Here, the media information may be any picture or text that can identify the other party. For example, the media information may include media objects such as avatars, still images, videos, texts, and audio. The avatar is a person image that can symbolize itself (sender or receiver), and can be downloaded by accessing the Internet or the like using the communication terminal 30.

In addition, the still image or moving image may be obtained by storing an image such as a face image of the self using a camera attached to the terminal, and may be directly stored and used by using a digital camera or a camcorder. You can download it via

On the other hand, the communication terminal 30 allows the caller to select whether to send the media information when the call attempt.

In addition, the receiver may select whether to output the received media information, and may select whether to store the received media information in the media information database 32, so that the receiver can select and use the stored media information again. do.

Meanwhile, the message processing unit 33 is a system for establishing and releasing a SIP message connection, transmitting predetermined information, and receiving confirmation information for receiving the information.

To this end, the message processor 33 is configured with the SIP configuration processor 34 constituting the SIP message (36-1) so that the media information and the call-id corresponding to the media information, and the sent or received media information A media data encoder and decoder unit (35) for compressing and restoring for transmission and output, an RTP / RTCP layer (36-2) and a TCP / UDP layer (36-3) for providing an interface for transmitting media information; And a protocol stack 36 including an IP layer 36-4 for packetizing media information.

The media data encoder and decoder unit 35 encodes the media information selected by the sender in order to display the media information on the receiving terminal to enable compression transmission.

In addition, when receiving the compressed media information, it is decoded by the media data encoder and decoder unit 35 so as to be output through the playback unit 37 of the terminal.

In this case, the playback unit 37 refers to a screen window for displaying an image related message among the media information and a speaker for outputting a ringtone.

Meanwhile, the SIP configuration processor 34 includes the encoded media information and the call-id of the media information in the SIP message, and configures the SIP message so that the receiver terminal can distinguish the included information.

Then, using the protocol stack 33 to provide an interface that can be transmitted in units of packets using the RTP / RTCP protocol based on the TCP / UDP protocol to transmit the encoded media information to the receiving terminal over an IP network. Done.

That is, to perform transmission and reception information acquisition (for example, caller / receiver IP information) using the SIP message so that packet transmission of caller media information is performed through an interface between a caller terminal, an IP network, and a receiver terminal. do.

For example, when a calling terminal transmits a SIP message through an IP network, the IMS server obtains transmission / reception information from the SIP header included in the SIP message, and then receives the caller media information from the corresponding receiver terminal. Will be sent to the terminal.

In this case, when the received media information is a video (AVI, MPEG, MOV, DAT, etc.), the media is converted into H.263 or MPEG4 type media information, but the media has a format that matches the screen resolution, color, etc. supported by the receiving terminal. Will be converted to.

Here, the media data encoder and decoder unit 35 of the receiver terminal may be converted into media having a format supported by the receiver terminal, and the converted media may be stored in the media information database 32 in real time. .

In addition, the message processor 33 generates a SIP message including encoded media information and call-id information corresponding to the media information when a call is attempted.

In detail, the body of the OPTIONS message of the SIP message includes the following information.

OPTIONS sip: JaeShin@150.150.67.222. SIP / 2.0

Max-Forwards: 70

Via: SIP / 2.0 / UDP 150.150.82.15

When the message is described, the OPTIONS message is a message for checking the capability supported by the receiving terminal, and is transmitted before the INVITE message as a message for exchanging between the sender and the receiving terminal or between the receiving terminal and the server when establishing a session. Message.

The capabilities supported here are defined in RFC 3261, which describes the Session Initiation Protocol (SIP) with the types of data, extensions, and CODECs that the receiver can support.

The OPTIONS message uses UDP as a transport protocol, and includes call-id information 1 corresponding to media information included in the OPTIONS message.

In addition, the portion marked image / jpeg (2) in the 'Content-Type' header describing the Content and Type included in the OPTIONS message indicates that the still image data 3 is included in the OPTIONS message.

The INVITE message, which is a message transmitted after the transmission of the OPTIONS message, includes session description protocol (SDP) information including session information and call-id information identical to call-id information included in the OPTIONS message.

Therefore, the receiving terminal receives the caller's media information and the call-id information in advance through the OPTIONS message, and outputs the still image data to the receiving terminal when the caller ID information of the next INVITE message is transmitted.

The remaining message of the OPTIONS message and the INVITE message is generally applied to the SIP message rules used in the session establishment. When the call setup procedure is performed as described above, the caller attaches the incoming call signal or ring to the receiving terminal. Still image data is displayed on the screen window of the receiving terminal.

In this case, caller identification information (CID: Caller ID) such as a caller's telephone number or name may be displayed at the same time.

In addition, at least one or more of media information such as a moving picture, avatar, text, and audio as well as a still image may be included in the OPTIONS message and transmitted to the receiving terminal in the same manner as described above.

For example, if a still image and a voice recorded by the caller are transmitted to the receiving terminal, the still image is displayed on the screen and the voice is used as the ringtone of the receiving terminal. You can check the caller.

3 is a flowchart illustrating a caller display method according to an embodiment of the present invention, and FIG. 4 is a flowchart illustrating a caller display method according to an embodiment of the present invention.

3 and 4, when the caller selects data to be used as media information (S51), and the caller attempts to initiate a call using a communication terminal having a SIP client function (S52), the caller terminal at It sends an OPTIONS message to the IMS server to check the supporting capability of the receiving terminal.

In this case, the selected media information and call-id information of the media information are transmitted in a body of the OPTIONS message (S41, S53), and the IMS server transmits / receives information (eg, caller / The OPTIONS message is transmitted to the receiving terminal using the receiver IP information (S53).

At this time, the reception confirmation message ('200 OK') for the OPTIONS message received by the receiving terminal is transmitted to the calling terminal (S42).

Next, the same call-id information as the call-id information included in the OPTIONS message is included in the body of the INVITE message including the session establishment information and transmitted to the IMS server (S43), and the IMS server receives the received IMS server. The INVITE message for attempting to establish a session is transmitted to the terminal (S54), and a transmission confirmation message 100 trying indicating that the session establishment request is made is transmitted to the calling terminal (S44).

As such, as the INVITE message is transmitted to the receiving terminal, a response message 180 ringing indicating that the other party's ring is ringing is transmitted from the receiving terminal to the calling terminal through the IMS server (S45).

In this case, the call-id information of the OPTIONS message including the media information is compared with the call-id information of the INVITE message (S55). If the call-id information is the same as the result of the comparison, the media information is output to the playback unit of the receiving terminal. It is made (S56).

The media information may be stored in a media information database of a receiver terminal, and the stored media information may be used again by a receiver.

In addition, if the call-id information is not the same as the comparison result, the caller is displayed according to the matter set in the receiving terminal (S57).

In addition, when the called terminal responds to the call (S58), an acknowledgment message 200 OK including a status code is transmitted to the calling terminal (S46).

In addition, when the ACK request message is transmitted from the originating terminal to the receiving terminal via the server (S47), a session is finally generated to perform a call (S48, S59).

Subsequently, if an end message (BYE) for notifying the end of the call is transmitted (S49), it is notified that the end notification has been received through the end confirmation message (200 OK), and the session is released (S50).

Here, both the calling terminal and the receiving terminal can terminate the session by executing the termination message.

In another embodiment of the present invention, media information may be included in the termination message and the termination confirmation message. That is, the caller or receiver can be identified at the end of the call by transmitting the end message and the end confirmation message including media information to be transmitted by the user.

For example, the header of the termination message includes an opaque field and transmits the media information including the opaque field. In this case, the header may be an Authorization header and is formatted using a SIP configuration processor to include the media information in an opaque field.

In addition, the termination response message header includes a response-digest field or a warn-text field and transmits the media information in the fields. In this case, the header may be an Authentication-Info header or a Warning header, and format conversion is performed using a SIP configuration processing unit so that the media information is included in the response-digest field and the warn-text field.

Accordingly, the calling terminal and the receiving terminal may simultaneously transmit / receive the termination message and the termination confirmation message by including the media information, and analyze and display the media information on the terminal to confirm the receiver at the end of the call. And the receiver can check the sender. In addition, the transmitted / received media information is stored in a media information database of the terminal.

Such a method is not limited to the sender sending the media information to the receiver, and the sender and the receiver can simultaneously transmit the media information.

5 is a diagram illustrating a screen window of a communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 5A, a caller may select media information such as a caller's name, an image data representing a caller, and a voice to be transmitted from a calling terminal to a called terminal.

First, the caller may select the sender's name 60-1 or add a new name by using the User List window 60, and may select other media information according to the caller.

Thereafter, the MCID (Multimedia Calling ID) data to be transmitted to the receiving terminal, that is, the media information is selected in the setting window 62, and the selection of the media information is performed by the MCID Image 62-1 and the MCID Sound 62-2. ), And may include at least one or more of the menu of Other settings (62-3).

In this case, when the MCID Image 62-1 is selected, the MCID Image Setting Window 63 is displayed and the caller selects the desired image 63-1.

The MCID Image may be any picture in which the other party can identify the caller, and may acquire an image such as a face image of himself / herself by using a camera attached to the terminal, or may use a digital camera or a camcorder. The acquired image can be used directly or downloaded from the Internet.

In addition, when the MCID Sound (62-2) is selected, the MCID Sound Setting window (64) is displayed. Using this, the pre-stored music (64-1) or the pre-recorded caller's voice (64-2) can be selected. Will be.

The music may be downloaded through the Internet, and the voice may be recorded and stored in advance by using a terminal or other voice recording means, or the stored voice may be downloaded.

In this way, a video, text, avatar, or the like may be selected and transmitted.

For example, when several people use a single terminal, the called number is the same, but according to an embodiment of the present invention, the recipient may include the corresponding media information that symbolizes or wants to send the sender so as to identify who the sender is. Can transmit

You can also add a new sender's name and choose different media information based on the sender.

The media information can be downloaded via the Internet, can be obtained using a camera attached to the communication terminal, and the voice can also be recorded and ringed on the receiver's terminal.

In addition, the caller's name and the media information is interlocked and stored in the media information database of the calling terminal, so that the media information selected according to the caller's name may be displayed at the next call request.

Referring to FIG. 5 (b), the media information 63-1 or voice information 64-2 transmitted by the calling terminal is displayed on the screen window of the receiving terminal or output as a ring tone through the speaker to determine who the caller is. Make sure to check.

When the caller is called, the MCID Image 63-1 transmitted from the calling terminal is displayed on the screen of the receiving terminal 65 and the calling party identification information 65-1 is displayed.

As another example, the MCID Sound 64-2 transmitted from the calling terminal is output through the speaker of the receiving terminal 66, and the display window 66-1 displays the calling party according to the setting of the receiving terminal and identifies the calling party. Information 66-2 is displayed.

The caller identification information is a CID (Caller ID) service that generally displays the caller's telephone number or name being displayed on the screen of the receiving terminal.

As another example, when the caller simultaneously selects the MCID Image 63-1 and the MCID Sound 64-2, the media message, that is, one or more media information is included in a SIP message and transmitted to the receiving terminal. The image 63-1 is displayed on the screen window of the receiving terminal, and at the same time, the MCID Sound 64-2 is outputted to the speaker of the receiving terminal.

As described above, the present invention has an advantage that the sender terminal selects the media information and transmits the selected media information in the SIP message and outputs the media information to the receiver terminal so that the sender can be easily identified.
