1 is a block diagram schematically illustrating an entire system for performing a ringback tone service providing method to a calling terminal by using multimedia data stored in a called terminal according to a preferred embodiment of the present invention.

According to Fig. 1, the entire system comprises a calling terminal 100, a called terminal 110, a base station 120 and 122, a telephone station 125, a calling side exchange 130, a called side exchange 132 and a location register (HLR). Or VLR) 140.

The calling terminal 100 includes not only a mobile communication terminal including a PDA, a mobile phone, but also a wired terminal such as a general telephone.

The destination terminal 110 is a mobile communication terminal including a PDA and a mobile phone, and transmits not only sound source data but also multimedia data such as a video to a calling terminal 100 after a call (traffic channel) is set up until a voice call is performed. Perform. The data may be digital data or analog data. The calling terminal 100 does not store the received data, but temporarily stores it in order to convert it into an outputable format and then outputs the deleted data.

The called terminal 110 stores a plurality of data, and may transmit data corresponding to the calling terminal 100 to receive. For example, when the calling terminal 100 is a terminal that does not support video, only the sound source data is transmitted. Alternatively, when the multimedia data is sound source data, the called terminal 110 reproduces the sound source data and transmits the reproduced analog signal so that the calling terminal 100 outputs the voice received during a normal voice call. You can also output a signal. Alternatively, the called terminal 110 transmits one data, and the calling terminal 100 outputs the received data if the data can be outputted, and otherwise deletes the data. That is, the called terminal 110 may transmit the stored multimedia data to the calling terminal 100 regardless of the type of the calling terminal 100.

The calling exchange 130 performs a function of setting a traffic channel between the calling terminal 100 and the called terminal 110 through the called exchange 132 when a call connection request is made from the calling terminal 100. Here, the source exchange 130 receives the information on the destination terminal 110 from the location register 140, and transmits a message containing the received information to the destination side exchange 132.

The called side exchange 132 checks the state of the called terminal 110 in accordance with the message received from the calling side exchange 130 and establishes a traffic channel with the calling side exchange 130. Also, the called side exchange 132 transmits an alert message to the called terminal 110 to start a subscribed service through the called terminal 110 information received from the calling side exchange 130. Perform. An alert message (Alert With Information Message) is a message for providing information on a specific service or a specific command from the exchange to the terminal.

Here, the notification message is not necessarily limited to that generated by the exchange. It may be generated in all mobile communication network devices used for establishing a traffic channel such as a base station and a base station controller and transmitted to the receiving terminal 110. Hereinafter, the transmission of the notification message in the exchange will be described as an example, and the notification message will be described in detail with reference to the accompanying drawings.

The telephone station 125 performs a function of connecting the wired telephone to the communication network.

The location register 140 (HLR (Home Location Register) or VLR (Visit Location Register) is a database that stores information on a mobile communication subscribed terminal and has information on other subscribed auxiliary services. That is, the location register 140 stores subscription information according to a ringback tone service using multimedia data stored in the called terminal 110 according to the present invention. Therefore, the subscriber exchange 130 performs the function of providing the subscription information.

Herein, a ringback tone service using multimedia data stored in the called terminal 110 according to the present invention will be briefly referred to as a ringback tone service.

2A illustrates the format of a notification message according to a preferred embodiment of the present invention.

According to FIG. 2A, a notification message may generally include three fields including a record type, a record length, and a type-detail field.

The record type can generally be represented as an 8-bit binary. Record types include a display, a message waiting, and a record type indicating a signal for ringing at a called terminal. The bit that is not used is defined as a ringback tone service according to the present invention so as to be different from the conventional record type (eg, 10101010). Accordingly, the receiving terminal 110 receiving the notification message of the record type '10101010' recognizes the record type and transmits the multimedia data to the calling terminal 100 according to the ringback tone service.

The record length is a field representing the length of the entire record and can be expressed in 8 bits.

The type-detail field is a field in which the content of the notification message is stored, and the terminal may recognize the information of the notification message through this field. It is not necessary to store a separate content in the type-detail field in the notification message according to the ringback tone service, but it is natural that other messages may be stored. The type-detail field has as many bits as eight times the record length.

Here, the notification message does not necessarily need to be a message form consisting of the three fields described above, but may also be a synch signal that can be recognized by the called terminal 110.

Therefore, according to an embodiment of the present invention, the destination exchange 132 generates a notification message of the above-described form for the ringback tone service and transmits it to the destination terminal 110, thereby recognizing the destination terminal 110. The stored multimedia data can be sent to the calling terminal 100.

Figure 2b is a functional block diagram showing the configuration according to the function of the called terminal according to a preferred embodiment of the present invention.

According to FIG. 2B, the destination terminal 110 includes a transceiver 112, a service controller 114, a status code generator 116, and a memory 118.

The transceiver 112 receives a notification message from the exchange, transmits a status code to the exchange, or transmits multimedia data to the calling terminal 100.

The service controller 114 recognizes the notification message received from the exchange and performs a function of extracting multimedia data from the memory 118. In addition, a command for recognizing a call connection command when a user presses a call button is transmitted to a transmission / reception unit to stop transmission of multimedia data, thereby controlling transmission of multimedia data to perform a voice call connection.

The status code generating unit 116 performs a function of generating a status code which is information on whether the called terminal 110 transmits multimedia data according to the ringback tone service according to the present invention. The exchange does not generate and transmit a notification message when the status code is inactive according to the status code, and does not provide a ringback tone service according to the present invention. That is, the status code generated at the destination terminal is stored in the location register, and the exchange receiving the information determines whether to send the notification message in accordance with the status code. Thus, the status code is generated in the form of a numeric or character code that can be recognized by the exchange or location register 140 in correspondence with the user's button input.

The memory 118 stores the multimedia data to be transmitted to the calling terminal 100. In addition, it stores the data corresponding to the notification message to recognize that the terminal data ring back tone service.

3 is a diagram illustrating a process of providing a ringback tone service using multimedia data stored in a called terminal according to a preferred embodiment of the present invention.

According to FIG. 3, in step S310, the calling terminal 100 requests a call connection for a call with the called terminal 110. In step S315, the calling side exchange 130, which has received a call connection request from the calling terminal 100, requests information about the called terminal 110 from the location register 140, and in step S320, the call from the location register 140. Receive information. The destination terminal 110 information includes information on whether to subscribe to the ringback tone service. It also includes a status code indicating the active or inactive state of the service.

In step S325, the calling side exchange 130 transmits a call connection request message including information on the called terminal 110 to the called side exchange 132 corresponding to the received called terminal 110 information. 132 establishes a traffic channel with the source exchange 130, recognizes the subscription of the ringback tone service of the destination terminal 110 in step S330, and then, in step S335, the destination side exchange 132 is the destination terminal 110; Send a notification message). In operation S340, the called terminal 110 recognizes the contents of the notification message and transmits the multimedia data stored in the memory in the terminal to the calling terminal 100 through the set traffic channel accordingly. Here, the called side exchange 132 allocates the traffic channel set to the called terminal so that the called terminal 110 transmits the multimedia data to the calling terminal 100, and the charging process is preferably not performed. The called terminal 110 may transmit the multimedia data to the calling terminal 100 through a traffic channel in a push manner.

In step S345, the called terminal 110 requests a voice call connection to the called side exchange 132 according to the input of a button corresponding to the call, and receives a response from the called side exchange 132 in step S650. Here, the called side exchange 132 allocates the traffic channel as a channel for voice call between the calling terminal and the called terminal in response to a call request signal received from the called terminal, and from this time, it is preferable to process charging.

In step S355, the called terminal 110 stops transmitting the multimedia data and performs a voice call with the calling terminal 100.

Here, since the transmission of the multimedia data uses a traffic channel for voice call, in a communication network such as CDMA, if the multimedia data is a large data such as a video, a delay due to transmission may occur, but W-CDMA and WiBro Voice over Internet Protocol (VoIP) such as (WiBro) enables the transmission of multimedia data in various formats.

In order to provide a ringback tone service using data of the destination terminal 110, service subscription information should be registered in advance in the location register 140. In addition, the service subscription information includes a status code for determining whether to provide a service. Registering service subscription information in the location register 140 may be performed by a mobile service provider, or may be performed by a separate service provider. Hereinafter, a process of registering service registration information and registering or changing a status code in the location register 140 will be described in detail with reference to the accompanying drawings.

4 is a diagram illustrating a procedure for registering subscription information and changing a status code in a location register for providing a called terminal data ringback tone service according to an exemplary embodiment of the present invention.

According to FIG. 4, in step S410, the location register 140 receives ringback tone service subscription registration information including information of a service subscribed terminal. Here, the location register 140 stores the information of the terminal in advance. For example, basic information on location information, phone number, etc., and various additional service subscription information on whether or not the user is subscribed to other services are stored. The location register 140 stores ringback tone service subscription information in addition to the terminal information as it receives ringback tone service subscription information.

In step S420, a status code is received from the terminal registered with the service through the exchange. Here, the status code represents the active or inactive state of the terminal for the ringback tone service. If the status code is active, the terminal may be provided with ringback tone service. If it is inactive, the terminal does not receive ringback tone service. Therefore, the terminal may be provided with the data ringback tone service according to the request of the terminal user, or may not be provided.

The location register 140 checks and stores the location information of the terminal from time to time through the exchange and the base station. At this time, you can receive the status code of the terminal. Here, the location register 140 may receive a status code each time when checking the status of the terminal, but may receive only when the status code of the terminal is changed. Therefore, when the service registration information is registered in the location register 140 for the first time, it receives and stores the status code from the terminal, and receives the status code only when the status code is changed thereafter. In addition, a method of recognizing the change by the location register 140 is to transmit a specific signal according to the change of the status code in the terminal, and to receive the status code from the exchange receiving the update and update the stored subscriber information Can be.

Here, the status code is not necessarily recognized by the location register 140, it should be information that can be recognized by the exchange. That is, in order to provide the called terminal data ringback tone service according to the present invention, the exchange recognizes the state information and transmits corresponding data to the called terminal 110 when it is activated. As the status information, numbers, character codes, etc. may be used. For example, the exchange recognizes that a status code of 01 is active and 10 is inactive. Alternatively, the location register 140 recognizes the status code and transmits the corresponding data to the exchange, and the exchange recognizes the status code and provides the service.

It will be apparent to those skilled in the art that the above-described service registration procedure of the terminal can be used in the same manner as the existing general additional service generation and registration procedure, and thus a detailed description thereof will be omitted.

In step S430, the location register 140 compares the status code received from the terminal with the previously stored status code. In other words, when receiving a status code from time to time, it is determined whether the status code has changed. Therefore, when the status code is changed from the active state to the inactive state or from the inactive state to the active state, the changed state code is stored accordingly.

As another method for setting and changing the status code described above, without checking the status code from time to time, the destination exchange 132 checks in real time the information of the destination terminal 110 with the calling terminal 100 and the traffic channel set up. Can be used. With the traffic channel established, the destination exchange 132 requests the destination terminal 110 for information about the status code, and the destination terminal 110 receives the current status code (code for active or inactive status) of the terminal. Send to the destination exchange 132. Therefore, the receiving side exchange 132 receiving the received state code and correspondingly transmit the notification message to the destination terminal 110, thereby providing a ringback tone service.

5 is a diagram illustrating a process of providing a called terminal data ringback tone service at a called side exchange according to a preferred embodiment of the present invention.

According to FIG. 5, a call connection request message is received in step S510. The call connection request message is a message for requesting the establishment of a traffic channel and is received from the originating exchange 130 including information of the originating terminal 100 and the terminating terminal 110. Here, the source exchange 130 receives the information on whether the destination terminal 110 subscribes to the service from the location register 140 and transmits the information to the destination side exchange 132. In addition, the terminating terminal 110 information includes information on whether or not to subscribe to the terminating data ring back tone service and the status code for the activation or deactivation of the service. Of course, the source exchange 130 and the destination exchange 132 may be the same exchange. That is, when the calling terminal and the called terminal belong to the same exchange area, the above-described functions of the calling exchange 130 and the called exchange 132 are performed by the one exchange.

In step S520, the called side exchange 132 establishes a traffic channel between the calling terminal 100 and the called terminal 110 through the calling side exchange 130. In this case, the traffic channel may be configured in the same manner as that of the existing traffic channel. Therefore, it will be apparent to those skilled in the art, so detailed description thereof will be omitted.

In step S530, the called side exchange 132 checks whether the called terminal 110 has subscribed to the called terminal data ringback tone service through the called terminal 110 information.

In step S540, when the called terminal exchange 132 recognizes that the called terminal 110 subscribes to the called terminal data ringback tone service, it determines whether the called terminal 110 is active or inactive through a status code.

If it is active in step S550, the corresponding notification message is transmitted to the called terminal 110, and the called terminal 110 receiving the notification message in step S560 transmits the multimedia data stored in the internal memory through the traffic channel. The traffic channel is allocated to be used by the terminating terminal 110 so as to be transmitted to the terminal 100. Accordingly, the called terminal 110 transmits the multimedia data stored in the internal memory to the calling terminal 100 through the set traffic channel in response to the notification message. Thereafter, when the called terminal 110 is switched to the call mode by the user, the call is requested to the called exchange in order to stop transmission of the multimedia data and perform a voice call, which is received by the called exchange in step S570. A voice call is performed between the calling terminal 100 and the called terminal 110 through the preset traffic channel.

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