Description

Method and apparatus for processing video transmission using SIP over IP based NGN and 3G networks {The method and system for the multimedia tone in NGN or 3G-Network based IP instead of the normal tone in the current telecommunication}

The present invention relates to a method and related apparatus for providing in the form of a video in a newly developed NGN or 3G communication network for various tones used in an existing communication network. Unlike the voice provided in the existing network, this includes a method of allowing the service user to designate a video type so that the caller can watch the desired video.

In the existing telephone network, the tone is used to inform the caller of the system status or the call connection process until the call is made while the telephone network user wants to make the call. That is, by generating various tones depending on the system state or the call connection state, the caller can know the call connection state. However, in the current stage where the network accepts multimedia, it is desirable to provide various video formats in the new NGN and 3G networks based on the packet network rather than the existing simple voice tone.

In other words, the tone used in communication networks such as general telephone networks and mobile networks is a sound with a certain interruption period and frequency specified by the ITU-T specification, so that service users can recognize the usage of various tones to know the system status and call connection status. It is very inconvenient, and it is insufficient to provide a service that matches the user's personality and purpose by transmitting a uniform tone, so if it is provided in the form of a video, the service user can visually and auditively inform the call connection process and the status of the misconnection. Through the recognition through the call connection state can be more efficiently identified, and by providing a variety of videos specified by the personal tendency can provide an effective service that meets the user's personality and purpose.

In addition, in the call connection method using SIP proposed in the Internet, the tone signal is effectively received from the terminal rather than the communication network. It is difficult to recognize. Therefore, by providing the same uniform management of the tone signal by providing the same in the communication network as the method used in the existing telephone network, the service user can effectively recognize the exact state of the call connection state.

According to the present invention, in constructing NGN, All-IP, and 3G networks, which are new telephony networks based on packet networks, SIP protocols are applied to appropriate video according to call connection process and status by applying the concept of tones used in the existing exchange network. By using to provide a service suitable for the new network concept to the service user, and also to allow the user to specify the video provided according to the personality of the service user.

Accordingly, the technical problem to be achieved in the present invention includes a type of image to be used in a new network, a method of providing an image, information management for providing an image, and a system and a system configuration method necessary for replacing the existing tone use concept. .

Unlike conventional telephone calls in wired and wireless communication networks, the network consists of packet networks in NGN or All-IP networks. Therefore, in NGN and All-IP network, call connection is made by using protocol proposed in Internet network such as SIP, rather than using the existing connection network such as ISUP and Q.932. In this case, SIP is in the process of accommodating and adding existing protocols in consideration of interworking with existing telephone networks.

According to the present invention, the call connection process in the wired / wireless network is proceeding in the direction of using SIP in the future network evolution stage, and the call between the caller and the called party using the call connection protocol proposed by the Internet such as SIP It consists of the process of sending a video to the corresponding function to respond to the tone that informs the caller of the process in the process of connecting and the equipment therefor.

In addition, the present invention provides a base for providing a systematic and efficient management and stable service of the network provider by providing the above video in the system configured in the network, and also to select and send a specialized video for each subscriber of the service user Make it possible to use individual characteristics.

Network configuration and network elements for providing the functions described in the present invention are described in detail in FIG. As shown in Figure 1, the network elements for the present technology include HLR / HA (100: Home Location Register / Home Agent), SCP / AS (110: Service Control Point / Application Server), Billing Server (120), MGC / Softswitch (130: Media Gateway Control, SIP Proxy / Softswitch), AG (140, 190: Access Gateway), RAN (150, 200: Radio Access Network), MG (160, 180: Media Gateway), IP Backbone Network (170) , Media Server 210, CP Server (220: Contents Server), Subscriber Management Server (230), Web & Wap Server (240), and the like. The HLR / HA 100 has additional service registration status information for the subscriber and routing information for the Media Server, and thus, transmits the subscriber information at the request of the MGC / SS 130. When the service subscriber requests a call connection, the MGC / SS 130 requests and transmits a tone replacement video to the media server 210 according to the call connection process and status, and the media server 210 controls the MGC / SS. The video is sent out under control. The CP server 220 controls the service registration and deletion request of the subscriber, and performs a function of changing the information on the transmitted video under the control of the subscriber. Web & Wap Server 240 performs a function of changing the information on the video transmitted through the WEB or WAP under the control of the subscriber. The Subscriber Management Server 230 manages detailed information for the service, such as whether to subscribe to a service registered subscriber and video information, and delivers necessary information at the request of the Media Server 210.

The present invention is a technique that is different from the technology that listens to the ringback tone in the form of processing in the existing SIP terminal by a method applying a function that provides a ringback tone, etc. used in the existing telephone network in the call connection process using the conventional SIP, 2, 3 and 4 are diagrams illustrating the existing process and the new process, FIG. 1 is a normal call connection process in a conventional SIP network, and FIG. 2 is a process of transmitting a video replacing a Langback tone. In addition, Figure 3 shows a process of transmitting a ringback tone video when the subscriber is the originating.

Referring to FIG. 1 illustrating a multimedia access control process in an Internet network using an existing SIP, an originating subscriber makes an incoming connection to an INVITE to an originating MCC / SS 130 through an originating AG / RAN / MG (140/150/160). If requested (step S201), the originating MCC / SS 130 sends a processing response thereto (step S202) and delivers INVITE to the incoming MCC / SS 130 again (step S203). The incoming MCC / SS 130 sends a response signal to the originating MCC / SS 130 (step S204) and delivers the INVITE to the destination AG / RAN / MG (180/190/200) connecting the called party (step S204). ). The receiving AG / RAN / MG (180/190/200) receives the incoming request INVITE (step S205) and controls to send the ring to the receiving terminal, and then the receiving subscriber's ring transmission state to the receiving MCC / SS 130. Notify (step S206). This state is transmitted to the calling terminal through the calling MCC / SS 130 and the calling AG / RAN / MG (140/150/160) (steps S207 and S208). When the called terminal responds in the ring transmission phase, an OK message is sent to the destination AG / RAN / MG (180/190/200), the destination MCC / SS 130, the originating MCC / SS 130, and the originating AG / RAN / It is sheared to the calling terminal through the MG (140/150/160) (step S209 ~ S211). The calling terminal receiving the OK response message of the called terminal makes a video call by directly sending an ACK message to the called terminal (step S212) (step S213).

Normally, the telephone connection process in the existing circuit network informs the caller by connecting the ringback tone to the caller in this state, and informs the status of the call connection process. In the above-described process, the ringer is sent to the called party. The calling party's status remains idle until the subscriber responds. Therefore, it is necessary to send a video that plays the role of ringback tone. 3 is a diagram illustrating a procedure for transmitting a ringback through substitute video in a SIP network.

3 is a process illustrating a case where a calling subscriber is registered as a subscriber requesting a function to which the present invention is applied. In Fig. 3, when the originating subscriber sends an INVITE as an originating request to the originating MCC / SS through the originating AG / RAN / MG, it performs a response (step S301 to S302), and the originating MCC / SS delivers it to the destination MCC / SS. Before doing this, INVITE is sent to the media server, and the media server immediately responds to it (steps S303 to S304). Receiving the OK from the Media Server, the calling terminal connects the traffic path for the video by ACK and transmits the ringback tone replacement video through the ACK (steps S305 to S307). Detailed procedures for transmitting a video from the Media Server are described with reference to FIGS. 10 and 11. In this process, outgoing MCC / SS sends INVITE to incoming MCC / SS immediately after sending INVITE to Media Server and receives RINGING in response. The calling terminal is already receiving video. Because of this, the originating MCC / SS manages only the status of the called terminal (steps S308 to S312). When the called subscriber responds while the ring is ringing at the called terminal, an OK message is transmitted to the called MCC / SS and the calling MCC / SS through the called AG / RAN / MG (steps S313 to S314). Then, when the originating MCC / SS sends a REPLACE for changing the traffic connection with the called terminal through the originating AG / RAN / MG, the originating terminal responds to the originating MCC / SS with OK and responds to the called terminal with an ACK. A call is formed by configuring a traffic path with the terminal (S315 to S318).

FIG. 4 is a process similar to that of FIG. 3 except that the called party requests a function to which the present invention is applied. Therefore, access control to the Media Server is performed by the destination MCC / SS.

5 is a table for managing information on subscribers, and a table managing whether to use additional services and the IP address of a media server where a video is stored when using this service should be stored and managed. Represents a table to do. The table indicating whether to use the supplementary service is indicated by turning on or off the field for this service. The IP address of the media server stores and manages the actual IP address.

Figure 6 is a table showing the types that can be provided as a video from the tone of the existing network, and the ringback tone, non-response tone and busy tone are displayed to show three kinds of video. Each video stores information indicating the meaning of using a video commonly used in a network or using video information designated for each subscriber.

FIG. 7 shows a table managed by each subscriber in the subscriber information management server for the videos shown in FIG. The subscriber using this service stores and manages the telephone number information and the video information about the subscriber in the subscriber information server.

FIG. 8 shows a processing procedure for the case where the called subscriber status is notified of the busy state while the video is already being transmitted by the call control.

Fig. 9 shows a processing procedure for a case where the called subscriber status is not answered to the incoming request and is not answered (No Answer) while the video is already being transmitted by the call control.

10 is a process of transmitting a video by determining whether to transmit a video commonly used in the network or to individually transmit a video designated by the subscriber after inquiring the subscriber's information when the video transmission is requested for the first time. Shows.

11 is a voice for informing a call connection state to another video that is commonly used according to the information of the subscriber in the state that the video is being transmitted, the arbitrary video designated by the subscriber is transmitted again, or the previously transmitted video. In addition, it shows the process of sending by selecting three methods such as sending.

As described above, the tone replacement video information transmission technology according to the call connection state in the multimedia network according to the present invention is suitable for NSN and 3G networks according to the evolution of information until the caller and the called party are connected. By providing a video, you can provide a higher level of service, and you can better inform the caller about the status of the call.

And if necessary, the video provided by the service user can be sent by the service user can express the personality of the user, or by inserting an advertisement for the individual can be effective for raising awareness.

In addition, even in the case of telecommunications operators, this service can be sold in the form of differentiated services to existing services, which can have a great effect on attracting customers and profits. Can be maximized.
