Abstract

PURPOSE: An image informing service method in an asynchronous mobile communication system is provided to transmit a still image or video on a screen of an origination terminal together with a sound color ring previously set by a callee in alerting a call. CONSTITUTION: When an origination terminal(11) originates a call to a destination terminal(18)(601,602), an origination MSC(Mobile Switching Center) checks subscriber position information and whether a supplementary service is subscribed(603), recognizes that a callee is subscribed for an image informing service(604), sets up a 3G-324M call(605), and establishes a data channel for a 3G-324M picture phone call to the origination terminal(11)(606). An image informing service server(17) transfers pre-set image information to the origination terminal(11)(607). The origination terminal(11) decodes the received image information and outputs it on a screen(608). The origination MSC sets up the 3G-324M call with a destination MSC(609) and the destination MSC establishes a data channel for the 3G-324M picture phone call to the destination terminal(18)(610). When the picture phone session is terminated, the connection of the 3G-324M picture phone call is released(611).

Method of image alerting service in asynchronous mobile communication system {Method of image alerting service in asynchronous wireless telecommunication system}

The invention image Notify method and relates to a computer-readable recording medium recording a program for realizing the above method, in particular ^{3GPP (3 rd Generation Partnership Projects)} UMTS (Universal Mobile Telecommunication Service in the asynchronous mobile communication system, Or in the asynchronous next-generation mobile communication system such as W-CDMA (Wideband Code Division Multiple Access), when a call is received with a sound color ring service, Independently set still image, video, etc. is transmitted to the screen of the calling terminal (image color ring service).

In the current mobile communication method, a specific sound set in the reception terminal itself or a specific character (CNAP: Call Name Presentation) can be expressed. In fact, international standards may use a specific sound generated by the network, but most operators and terminal manufacturers set the received sound at the terminal itself and commercialize it.

However, most current mobile communication terminals have simple multimedia functions, and all future terminals have video on demand (VOD) and video telephony functions that have MPEG-4 (Moving Picture Expert Group-4) functions. will be.

Nevertheless, in the conventional mobile communication network, due to the problem of size of the image, the image could not be transmitted at the time of the terminal alerting. Furthermore, the voice-oriented circuit network and the packet data-oriented packet network operate independently of each other. Since the subscribers could not meet the needs of subscribers (especially image color ring service), they could not satisfy their multimedia service needs.

According to the trend of adding and strengthening multimedia functions of the mobile communication terminal, if a still image or a video can be transmitted to the terminal screen capable of color display at the same time as the ringing tone of the terminal, the receiver (recipient) can set the image of himself / herself. By sending a still image or a video to the caller, the caller who is calling the user can be notified of his / her appearance in advance, and has the advantage of expressing his own unique character. Therefore, such a method is urgently required in the current technical field.

The present invention has been proposed in order to meet the above-mentioned demands, and particularly, when a call is received in an asynchronous mobile communication system (W-CDMA), the receiver (called party) sets music together with the transmission or It is an object of the present invention to provide a video notification service method for transmitting a still image, a moving picture, and the like, which is set independently, to a screen of a calling terminal, and a computer-readable recording medium storing a program for realizing the method.

In the existing mobile communication network, there is a difficult to send the terminal the notification (alerting) during image problem because the image size, the mobile communication network is evolving as the CDMA-2000 is available to transmit the SVD (Simultaneous Voice and Data) and, 3GPP (3 ^rd In Generation Partnership Projects (UMTS) or Universal Mobile Telecommunication Service (UMTS) or Wideband CDMA (W-CDMA), the transmission speed is increased so that an image can be transmitted when the terminal is notified.

Accordingly, in the present invention, a voice-oriented circuit network and a packet data-oriented packet network are interworked with each other, and a specific server (video notification service server) is established in the packet network to notify the terminal. Sends video (still video, video) to the screen of the calling terminal. In particular, in the case of W-CDMA, since there is a mutual interface between a circuit network and a packet network, this can be more easily implemented.

That is, in the present invention, the multimedia information defined by the receiver (called party) before the video call session with the called terminal is opened in the outgoing mobile terminal using the 3G-324M video telephone method defined in the international standard in the W-CDMA method. (Particularly, a still image, a video, etc. which are set in advance by the called party) are transmitted to the calling mobile communication terminal.

To this end, there is no significant change on the terminal, and the core network can be implemented by supplementing the processing procedure a little. The basic principle of this is that the multimedia information (especially, to the outgoing mobile terminal) is linked with the multimedia server (video notification service server) configured separately from the outgoing mobile terminal before the 3G-324M video call session with the called terminal. The video specified by the called party).

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of an asynchronous mobile communication system to which the present invention is applied.

Mobile stations (MSs) 11 and 18 are mobile communication terminals such as PDAs (Personal Digital Assistants), notebooks, cellular phones, or PCS phones, which users can carry and communicate with, and IMT-2000 (International). It includes next-generation mobile communication terminals such as Mobile Telecommunication (UMT), Universal Mobile Telecommunication Service (UMTS), and the like. In particular, an asynchronous mobile communication terminal capable of displaying an image simultaneously with a dial tone or independently by interworking with an asynchronous mobile communication network (W-CDMA) it means. However, especially in the case of W-CDMA, since there is a mutual interface between a circuit network and a packet network (that is, a general packet radio service (GPRS) network), the mobile communication terminals 11 and 18 are connected to a circuit ( It has a function to enable circuit-type telephone service and packet service.

Here, the circuit network is a network structure for providing a voice service, the network is composed of a base station associated device 12, a switch (MSC), etc. In particular, the GPRS network is a network structure for providing a packet service, 12), the network is composed of a packet switch (SGSN: Servinvg GPRS Support Node) / packet network gateway (GGSN: Gateway GPRS Support Node) (GGSN) (16), and is accessed by the mobile communication terminals (11, 18).

A base station related device 12, such as a base transceiver system (BTS) / base station controller (BSC), has a voice service between a mobile communication terminal (MS) 11, 18 and an exchange (MSC) 13. In particular, it is responsible for the transmission and buffering of packet data between the mobile communication terminal (MS) 11, 18 and the packet switch (SGSN) / packet network gateway (GGSN) 16, and moves the packet data in the GPRS network. Paging is also performed when transmitted to communication terminals (MS) 11, 18.

Here, the base station (BTS) may support a circuit-based telephone service and a packet service, and transmit radio signals and traffic to a circuit network or a GPRS network, or transmit voice data of a circuit network or packet data of a GPRS network to the mobile communication terminals 11 and 18. It serves as a).

The base station controller (BSC) accepts the functions of the existing exchange (MSC) 13 as it is, and controls and manages one or more base stations (BTS), traffic and signaling methods related to call processing, mobility management, mobile terminal management, etc. Do this.

In particular, the packet switch is named as Sergig General Packet Radio Service (SGSN) Support Node (SGSN) in 3G communication network of Wideband Code Division Multiple Access (W-CDMA), and Packet Data Support Node (PDSN) in 2G CDMA network. The gateway is referred to as a Gateway GPRS Support Node (GGSN) in a W-CDMA 3G communication network and a Packet Data Gateway Node (PDGN) in a 2G CDMA network.

The packet switch (SGSN) 16 is a node that supports packet service, and serves as a signal and traffic transfer between the base station and the packet network gateway (GGSN) (16). In addition, the packet switch (SGSN) 16 provides a session management and mobility management function for the subscriber to support the packet data service of the GPRS subscriber. In addition, the packet switch (SGSN) 16 performs the function of the end of the packet network gateway (GGSN) 16 and the GPRS Tunneling Protocol (GTP) which is a tunneling protocol of GPRS.

Meanwhile, the packet network gateway (GGSN) 16 serves as a gateway with the Internet. That is, the packet network gateway (GGSN) 16 performs the gateway function of the GPRS network and interfaces with the video notification service server 17.

The Home Location Register (HLR) 14 has information such as subscriber information, IP priority, and resource and authority usage for interdomain services.

The mobile subscriber management server 15 is responsible for AAA (Authentication, Authorization, Accounting) functions, that is, subscriber authentication, authorization verification, billing, and the like, and authentication request and billing messages requested from the packet data service node (PDSN) 16. Serves to handle and so on.

Next, an image alerting service (image alerting service or image color ring service) in an asynchronous mobile communication system according to the present invention will be described.

For the video notification service of the present invention, the exchange 13 provides a voice service between callers in an asynchronous mobile communication system (W-CDMA), and the home location register 14 provides mobile subscriber location information and additional services. Maintain information.

Meanwhile, for the video notification service of the present invention, the packet switch / packet network gateway (SGSN / GGSN) 16 provides a data service in an asynchronous mobile communication system (W-CDMA), and the video notification service server 17. Provides an image alerting service or an image color ring service of the present invention.

On the other hand, for the video notification service of the present invention, the content providing server 20 is a Web server (WEB sever) 21 to select the content to be used for the video notification service on the Internet, wireless content to be used for the video notification service A user connected via a WAP (Wireless Application Protocol) server (22) to select on data, and an auto responder (ARS) 23 to select contents to be used for the video notification service on the wired ARS. That is, the called party or receiver can access the video notification service server 17 so that the called party (recipient) can select contents to be displayed on the screen of the calling party terminal 11 when a call is made to him.

Therefore, a receiver (recipient) who wants to transmit a still image, a video, etc., which are preset at the time of call notification, to the screen of the outgoing mobile communication terminal 11 is the user terminal such as his mobile communication terminal 18 or a PC. 19, the still image and the video to be transmitted to the mobile communication terminal 11 of the caller who calls the video notification service server 17 through an asynchronous mobile communication network (W-CDMA) or the Internet. Etc. can be set in advance. In this case, various methods using the web server 21, a WAP server 22, an automatic answering device (ARS) 23, and the like may exist as described above.

First, after examining the general procedure of the video notification service of the present invention, the video notification service procedure using the 3G-324M video telephone method will be described.

The video notification service server 17, which transmits an image at the time of terminal alerting or provides a convenient device to the subscriber, has an IP connection and a home location register 14 (or a switch ( 13)) It should be connected with No.7 signal network for connecting.

Basically, the subject that starts the image alerting service (image alerting service or image color ring service) is made through the home location register 14 at the switch 13, and the contents thereof are transmitted to the video alerting service server 17. It is transmitted to the outgoing mobile terminal 11 through the packet switch / packet network gateway 16.

The image alerting service (image alerting service or image color ring service) of the present invention is based on the condition that SVD (Simultaneous Voice & Data) is possible in the wireless section. That is, it must have a structure capable of transmitting data and voice simultaneously in the wireless section.

If the outgoing mobile communication terminal 11 calls the incoming mobile communication terminal 18 via the switch 13, the switch 13 retrieves the terminal capability from the home location register 14 (subscriber location). Information and additional service subscription confirmation), and then inform the base station of the VP mode (the method of providing SVD) (the structure capable of transmitting voice and packet data at the same time). Then, the base station recognizes that the image is transmitted at the time of alerting, allocates the communication line through the interface with the packet switch / packet network gateway 16 while paging to the terminating mobile communication terminal 18.

Then, for the image alerting service (image alerting service or image color ring service) of the present invention, the exchange 13 receives a response from the base station and then through the home location register 14 (or directly at the exchange 13). When the notification (alerting) is linked to the image notification service server 17 for processing the image. Then, the video notification service server 17 transmits the already set video (receive subscriber-specified video) to the packet switch / packet network gateway 16, and the packet switch / packet network gateway 16 transmits the base station according to network synchronization. Will form a session.

Finally, the base station is responsible for the alerting sound and other call processing functions generated from the switch 13, and the packet exchange / packet network gateway 16 receives the video information received from the video notification service server 17 (incoming subscriber). Transfers the specified video data) to the calling mobile terminal 11.

At this time, the SVD data channel is allocated between the calling mobile communication terminal 11 and the packet switch / packet network gateway 16, and the video notification service server 17 transfers the video data designated by the called subscriber to the packet switch / packet network gateway 16. The packet switch / packet network gateway 16 transmits the video data designated by the called subscriber to the calling mobile terminal 11 through the assigned SVD data channel.

The reason for using the SVD data channel between the packet switch / packet network gateway 16 and the originating mobile communication terminal 11 during the video alerting is because the size of the video data during the alerting is large. This is because the control signal processed in 13) does not provide a message enough to send an image.

And, the image displayed on the screen of the outgoing mobile terminal 11 should be configured in a simple form, a wavelet capable of a character-like image, a small form of natural image, such as the existing SIS service in the country (Wavelet) and the like, if the outgoing mobile terminal 11 has the function of MPEG-4, it is possible to play (play). Since each mobile communication terminal 11 and 18 has a function capable of processing an image and a difference in size and color of the LCD, the video notification service server 17 must manage this.

In some cases, it is possible to stream to the mobile communication terminals 11 and 18 so that the natural video can be transmitted to the outgoing mobile communication terminal 11. That is, it can handle 3GPP standard multimedia formats such as MP4 file format or 3GP.

If up to an alarm sound of the terminal is set, the video notification service server 17 may process audio together with the video. That is, during call notification, the receiver (receiver) transmits the preset music (sound color ring service), and transmits the preset still image, video, etc. to the calling mobile terminal 11 ( image color ring service or image alerting service). Of course, it is also possible to transmit a still image, a video, etc., which are preset independently of a preset sound color ring service, to the screen of the outgoing mobile communication terminal 11 (image color ring service or image alerting service).

In addition, a receiver (recipient) who wants to transmit a still image, a video, etc., which are preset at the time of call notification, to the screen of the outgoing mobile communication terminal 11 is the user terminal such as his mobile communication terminal 18 or a PC. 19, a still image and a video to be transmitted to the mobile communication terminal 11 of the caller who calls the user by accessing the video notification service server 17 through a synchronous mobile communication network (CDMA-2000) or the Internet. Etc. can be set in advance or the set image can be updated. At this time, there are various methods using a web server 21, a WAP server 22, an automatic answering device (ARS) 23, and the like, as described above.

Now, look at the 3G-324M video telephony method used in the present invention for the purpose of understanding with reference to FIG.

3G-324M video telephony is a video telephony standard that complements H.324, a wired network based video telephony system defined by ITU-T in 3GPP, which defines UMTS mobile communication standard. In other words, 3G-324M is a protocol that defines a wide range of methods that define video / audio codecs, multiplexing, transport protocols and adaptation.

The 3G-324M video codec defines H.263 by default, and additionally recommends the application of MPEG-4. Speech codec defines AMR (Adaptive Multi-Rate), which is a basic codec defined in 3GPP, for video telephony.

Since 3G-324M is basically a video telephony system for a circuit network, it is multiplexed and demultiplexed using H.223 defined by ITU-T. Control information such as videophone call setup uses H.245.

In order to set up a video telephone call, a call of a radio bearer terminal is set in the calling mobile communication terminal, and then a call of 3G-324M is set. In this case, circuit data defined in W-CDMA uses UDI (Unrestricted Digital Information) of a transparent connection type. Basically, for video telephony, circuit data transmission and reception speed is symmetrically defined as 64 kbps in QCIF (Quarter Common Intermediate Format: 176 × 144). This will transmit about 10 frames per second.

To set up 3G-324M video telephony, as shown in FIG. 3, a radio bearer of 64 kbps of circuit data is set in UMTS, and then H.245 is used to provide information required for video telephony setup. -to-peer) to negotiate.

At this time, in the CS (Circuit Switched) domain of the core network (core network) to process the call using the common line signaling method (No. 7) between the originating and destination exchange (MSC). This is to interwork with existing widely applied general telephone network.

In the present invention, a server (video notification service server 17) may be separately provided to an existing exchange (MSC) 13 to provide a service. To this end, the existing exchange 13 and the video notification service server 17 is interlocked by No. 7 or BICC. Here, the BICC is a signaling protocol between soft switches, and serves to efficiently deliver bearer information supporting various multimedia data.

At this time, whether to support the terminal, whether to subscribe to the subscriber, etc. should be stored in the home location register (HLR) 14 which is the subscriber information DB linked to the exchange 13, and the exchange 13 stores the home location register 14. If the query is subscribed to set the call to the video notification service server (17). When a 3G-324M session is opened at the destination terminal 18, a video telephone call is set up from the originating exchange MSC to the destination exchange MSC.

However, for the video notification service of the present invention, the originating exchange (MSC) confirms whether or not to subscribe to the video notification service to the home location register 14, and then first set the video notification service server 17 and 3G-324M call At the same time, 3G-324M is set as the outgoing mobile communication terminal 11. In fact, the video notification service server 17 is configured as a DB for information about the terminal capable of 3G-324M.

In general, since it takes a long time to set up an end-to-end video telephone call, in the present invention, the switch 13 of the core network can be supplemented to handle related calls, so that the caller It can be a very advantageous service.

In this case, the mobile communication terminals 11 and 18 have little parts to modify, and since the communication target is changed in H.245 in charge of call processing in the 3G-324M (the video notification service server 17 calls the calling terminal ( 11)) and, accordingly, a call is set to a predetermined value for capability negotiation, etc. handled in H.245 for quick access by the video notification service server 17.

The present invention proposes two methods of multimedia information processing.

In the first method, the video notification service server 17 separately manages and stores multimedia information stored by each subscriber into a video stream and a speech stream in order to match the protocol with 3G-324M. A method of transmitting to the mobile communication terminal 11.

The second method is a method in which the video notification service server 17 stores multimedia information according to a file format, and then transmits the multimedia information to the calling mobile terminal 11.

First, a program for processing 3G-324M is basically set in the video notification service server 17, and has a large DB to store and process multimedia information of each subscriber. The multimedia storage form for this is as shown in FIG.

The video notification service server 17 manages the stored multimedia information into a file header and a multimedia stream, such as a file header and a video stream, as shown in FIG. 4, wherein the file header is a video codec. codec (e.g., H.263), speech codec (AMR, etc.), total length (size), image size (QCIF, etc.), speech code sampling rate (6.3kbps, etc.) ), And the date of initial storage.

However, when managing the multimedia information as shown in Figure 4, there is an advantage that can be processed without changing the existing 3G-324M terminal, there is a disadvantage that the multimedia information in the video notification service server 17 does not have various compatibility. . In other words, when editing or transmitting multimedia content on a general Internet, there is a disadvantage in that a specific tool is used instead of a general authoring tool.

On the other hand, when using the Internet or internationally defined file format (file format), there is an advantage that can easily produce multimedia content, free transmission and reception. However, since it is not a normal 3G-324M call processing, a software block for processing the same should be mounted in the mobile communication terminals 11 and 18. In addition, it should be able to recognize and play the new file format in the existing H.245 signaling protocol. This configuration can be easily defined in existing parameters.

In the file format defined in the present invention, a general MP4 file format can be used as shown in FIG. 5, which is also compatible with the 3GPP standard.

In addition to the MP4 file format, the 3GP file format defined by the Packet Streaming Service (PSS) defined by 3GPP can be used.If 3GP is used, the 3GPP VOD file format can be used. It is compatible with) and has advantages in content creation.

If 3G-324M defined in 3GPP, H.323 defined in packet network, 3GCF defined in 3GPP2, SIP multimedia telephony of 3GPP, etc. This can be solved using .723.1, and interworking using the same file format as MP4.

6 is a flowchart illustrating a video notification service method according to an embodiment of the present invention, in which a receiver (called party) is opened before a video call session with a called terminal 18 is opened in an outgoing mobile terminal 11 using 3G-324M. A procedure of transmitting the defined multimedia information (especially, image data designated by the called subscriber) to the calling mobile terminal 11 is shown.

For the video notification service of the present invention, the content providing server 20 may select a web server 21 for selecting the content to be used for the video notification service on the Internet, and select the content to be used for the video notification service on the wireless data. WAP server 22 to allow users to select content to be used for the video notification service on the wired ARS (ARS) 23 to access the video (ie, recipient or receiver) By allowing the notification service server 17 to be accessed, the called party (recipient) can select the content to be displayed on the screen of the calling party terminal 11 when a call is made to him or her, and the renewal thereof can be made later.

Therefore, a receiver (recipient) who wants to transmit a still image, a video, and the like, which has been set at the time of call notification, to the screen of the calling mobile terminal 11 may use his mobile terminal 18 or a user terminal such as a PC. 19, the still image and the video to be transmitted to the mobile communication terminal 11 of the caller who calls the video notification service server 17 through an asynchronous mobile communication network (W-CDMA) or the Internet. Etc. can be set in advance or the set image can be updated. At this time, there are various methods using a web server 21, a WAP server 22, an automatic answering device (ARS) 23, and the like, as described above.

First, a receiver (recipient) who wants to transmit a still image, a video, etc., which are preset at the time of call alerting, to the screen of the outgoing mobile terminal 11 for an image color ring service or an image alerting service. ) Accesses the video notification service server 17 through its mobile communication network (CDMA-2000) or the Internet through its mobile communication terminal 18 or a user terminal 19 such as a PC and makes a call to itself. A still image, a video, and the like to be transmitted to the calling party's mobile communication terminal 11 are set in advance. At this time, it is apparent that various methods using the web server 21, the WAP server 22, the automatic response device (ARS) 23, and the like may exist as described above.

Then, when the calling mobile communication terminal 11 sends a call to the called mobile communication terminal 18 (501, 502), the calling exchange (MSC) queries the home location register 14 to check the subscriber location information and whether to subscribe to the additional service. After confirming (503) that the called party (recipient) is subscribed to the video notification service (504), and set the video notification service server 17 and 3G-324M call (505), and at the same time outgoing mobile communication terminal 11 Establish a data channel for the 3G-324M videophone call (506).

Thereafter, a 3G-324M videophone call is established between the video notification service server 17 and the outgoing mobile communication terminal 11, and a 3G-324M videophone data channel capable of sending video information to the outgoing mobile communication terminal 11 is allocated. When the video call session with the called terminal 18 is opened, the video notification service server 17 transmits predetermined video information (video information designated by the called subscriber) to the calling mobile terminal 11 (507). Then, the outgoing mobile terminal 11 decodes the video information (video information designated by the called subscriber) received from the base station and outputs it to the screen (508).

Next, a video telephone session with the destination terminal 18 is developed. First, the originating exchange (MSC) establishes a 3G-324M call with the destination exchange (MSC) (509), and the destination exchange (MSC) is the destination terminal (18). In step 510, a data channel for a 3G-324M video call is established. When the video call session is completed in this way, the connection of the 3G-324M video call set up between the calling exchange (MSC) and the video notification service server 17 is released (511).

The following procedure is the same as the general 3G-324M video telephone call processing procedure, so a description thereof will be omitted here.

At this time, when the terminal (alterting), if the receiver (recipient) pre-set the music, display the received image (image color ring service or image alerting service) and at the same time with the music (sound color ring service) You can print Of course, if the alerting music is not set, only the image may be displayed on the screen independently, or the terminal itself may provide basic music when displaying the image. At this time, the image displayed on the screen of the outgoing mobile terminal 11 may be configured to disappear automatically when the call state, or may be configured to exist continuously until the end of the call. In addition, it is obvious that the image transmitted at the time of alerting may be stored in the memory so that the image may be viewed at any time or transmitted to another terminal.

7 is a flowchart illustrating another embodiment of a video notification service method according to the present invention.

For the video notification service of the present invention, the content providing server 20 may select a web server 21 for selecting the content to be used for the video notification service on the Internet, and select the content to be used for the video notification service on the wireless data. WAP server 22 to allow users to select content to be used for the video notification service on the wired ARS (ARS) 23 to access the video (ie, recipient or receiver) By allowing the notification service server 17 to be accessed, the called party (recipient) can select the content to be displayed on the screen of the calling party terminal 11 when a call is made to him or her, and the renewal thereof can be made later.

Therefore, a receiver (recipient) who wants to transmit a still image, a video, and the like, which has been set at the time of call notification, to the screen of the calling mobile terminal 11 may use his mobile terminal 18 or a user terminal such as a PC. 19, a still picture and a video to be transmitted to the mobile communication terminal 11 of the caller who calls the video notification service server 17 through a synchronous mobile communication network (CDMA-2000) or the Internet. Etc. can be set in advance or the set image can be updated. At this time, there are various methods using a web server 21, a WAP server 22, an automatic answering device (ARS) 23, and the like, as described above.

First, a receiver (recipient) who wants to transmit a still image, a video, etc., which are preset at the time of call alerting, to the screen of the outgoing mobile terminal 11 for an image color ring service or an image alerting service. ) Accesses the video notification service server 17 through its mobile communication network (CDMA-2000) or the Internet through its mobile communication terminal 18 or a user terminal 19 such as a PC and makes a call to itself. A still image, a video, and the like to be transmitted to the calling party's mobile communication terminal 11 are set in advance. At this time, it is apparent that various methods using the web server 21, the WAP server 22, the automatic response device (ARS) 23, and the like may exist as described above.

Then, when the outgoing mobile communication terminal 11 sends a call to the incoming mobile communication terminal 18 (701, 702), the outgoing exchange (MSC) queries the home location register 14 to determine subscriber location information and whether to subscribe to an additional service. After confirming (703) that the called party (recipient) is subscribed to the video notification service (704), and requests to allocate the SVD data channel to the base station (205). Then, the base station transmits the SVD data channel allocation request message to the calling mobile communication terminal 11 (706), and allocates the SVD data channel through the interface with the packet data service node 16 (707). It notifies the originating exchange (MSC) that the SVD data channel allocation has been successfully made (708).

Here, the SVD data channel allocation request message transmitted from the base station to the originating mobile communication terminal 11 indicates that an image is transmitted when an alarm is transmitted to a specific field of an extended channel assignment message (ECAM) that notifies the start of the SVD and sets the channel. Therefore, the outgoing mobile communication terminal 11 recognizes a specific field of the ECAM and recognizes that an image is transmitted at the time of alerting, thereby activating an image decoder in advance.

When the SVD data channel capable of transmitting video information to the outgoing mobile terminal 11 is allocated, the originating exchange (MSC) requests the video notification service server 17 to transmit the video designated by the called subscriber (709). In response, the video notification service server 17 transmits a preset video (receive subscriber-specified video) to the packet switcher / packet network gateway 16 (710), and the packet switcher / packet network gateway 16 performs network synchronization. In step 711, a session is established with the base station to transmit the video information (video data designated by the called subscriber) received from the video notification service server 17 to the base station.

Thereafter, the base station transmits the video information (video information designated by the called subscriber) received from the packet exchanger / packet network gateway 16 to the calling mobile terminal 11 (712). Then, the outgoing mobile terminal 11 decodes the video information received from the base station (video information designated by the called subscriber) and outputs it to the screen (712). The description will be omitted.

At this time, if the receiver (caller) has previously set music at the time of terminal alerting, as shown above, the received image is displayed (image color ring service or image alerting service) and at the same time with the corresponding music (sound). color ring service). Of course, if the alerting music is not set, only the image may be displayed on the screen independently, or the terminal itself may provide basic music when displaying the image. At this time, the image displayed on the screen of the outgoing mobile terminal 11 may be configured to disappear automatically when the call state, or may be configured to exist continuously until the end of the call. In addition, it is obvious that the image transmitted at the time of alerting may be stored in the memory so that the image may be viewed at any time or transmitted to another terminal.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention provides not only music preset by a receiver (recipient) but also multimedia information, such as still images and videos, which are independently set at the time of call notification in an asynchronous mobile communication system. Since it can be transmitted to the screen, in particular, it is possible to notify the caller who calls the user in advance, and the effect of expressing his own unique character is possible.
