Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a call waiting tone service system for providing a call waiting tone service according to the present invention.

Referring to FIG. 1, a call waiting system includes an incoming and outgoing mobile communication terminal 100 and 102, a wireless base station (BS) 104, a switchboard 110 and 114, a media gate, and a way controller (MGC). A gateway controller (116), a signal gateway (SG) 118, a coloring ring back tone (CRBT) server 120, a subscriber database 122, a sound source database 124, and the like.

The call waiting tone service according to the present invention requests a call from the calling mobile communication terminal 102 to the called mobile communication terminal 100 so that the called mobile communication terminal for the period until the call between the calling mobile communication terminal and the called mobile communication terminal is made. Refers to a service to which a call waiting sound selected and registered in advance by a user of the user 100 is transmitted. When a specific signal is received from the calling mobile communication terminal 102 during call waiting sound transmission, the call connection between the incoming and outgoing mobile communication terminals is stopped and the calling mobile communication terminal is stopped. In 102, the call waiting sound registered by the user of the incoming mobile communication terminal is continuously serviced. Packet network according to the technical company of the present invention is based on CDMA-2000 1xEV-DO, W-CDMA, Wireless LAN.

The mobile communication terminals 100 and 102 are terminals capable of conducting voice talk and video calls with each other through a mobile communication network, and performing data communication through a wireless Internet connection. In addition, the mobile communication terminals 100 and 102 are VoIP terminals or video terminals capable of transmitting and receiving voice packets and / or data packets and having unique IP addresses. That is, the mobile communication terminals 100 and 102, which are end points for performing voice, video, or data communication, perform voice calls, video calls, and data transmission / reception functions using respective unique IP addresses.

Here, the user of the terminating mobile communication terminal 100 is connected to the CRBT server 120 through the mobile communication network to register a sound source code to be used as at least one call waiting sound, and the incoming mobile communication terminal (102) In response to the call connection request to 100, the playback mode is set when the sound source is reproduced to the calling mobile terminal 102 with the call waiting sound.

The playback mode that can be set by the user of the terminating mobile communication terminal 100 is any one of a random mode, a sequential mode, and a normal mode, and the CRBT server 120 performs the originating mobile communication terminal 102 when the playback mode is a random mode. Whenever there is a call connection request from the user, a random sound source code is randomly selected from among the registered sound source codes and transmitted to the outgoing mobile terminal 102 with the call waiting sound, and when the playback mode is the sequential mode, the outgoing mobile communication Whenever there is a call connection request from the terminal 102, the sound source codes are selected in a preset order and transmitted to the outgoing mobile communication terminal 102 as a call waiting sound.

The outgoing mobile terminal 102 receives a random call waiting sound during call waiting after a call connection request to the incoming mobile terminal 100, and plays a specific key, for example, "# key, # * key, ## key" during playback. The call waiting sound reproduction can be controlled by transmitting an arbitrary control message to the CRBT server 120 by manipulating the etc. The reproduction control of the call waiting sound may use a call progress (CPG) message among ISDN (ISDN User Part) messages.

In the above description, the mobile communication terminals 100 and 102 are divided into incoming and outgoing mobile communication terminals, but the outgoing mobile communication terminal 102 and the incoming mobile communication terminal 100 apply for a call waiting sound service using a packet network. As the role of requesting a voice call and a video call is changed, it is natural that the incoming mobile communication terminal 100 and the outgoing mobile communication terminal 102 may be changed.

The wireless base station 104 basically provides a packet voice call service, a packet video call service, and a packet data communication service to the incoming and outgoing mobile communication terminals 100 and 102, and the base transceiver station (BTS) 105 And a base station controller (BSC) 106.

The base station transmitter 105 transmits and receives voice, video and data signals between the incoming and outgoing mobile communication terminals 100 and 102 by identifying the locations of a plurality of mobile communication terminals including the incoming and outgoing mobile communication terminals 100 and 102. And accepts a call attempt from the originating mobile communication terminal 102 to the destination mobile communication terminal 100 through a traffic channel of the signaling channel, and transmits the received call attempt to the originating base station controller 106. .

The base station controller 106 controls the base station transmitter 105 to perform various call processing functions such as support for incoming and outgoing call processing and message processing of the base station transmitter 105, and transmits the PDSN to the call request received through the base station transmitter 105. The packet is transmitted to the exchange 110 through the packet data switching node 108.

The exchange 110 performs functions such as address translation, access control, bandwidth control, call control, call authentication, and call management for the incoming and outgoing mobile communication terminals 100 and 102.

In addition, the exchange 110 determines whether the incoming mobile communication terminal 100 is a user subscribed to the call waiting service of the present invention. To this end, the switch 110 stores profile information of a mobile communication terminal registered with the switch 110. Here, the profile information includes a mobile identification number (MIN), an electrical serial number (ESN), and registered additional service information of the mobile communication terminal registered in the exchange 110. The exchange 110 determines that the incoming mobile communication terminal 100 is a terminal subscribed to the call waiting tone service and transmits a call setup request signal including the IP address, MIN, etc. of the incoming mobile communication terminal 100 to the media gateway controller 112. And to the signal gateway 118.

The media gateway controller 112 receives a call connection message from the exchange 110 to perform a call connection with the CRBT server 120, and the signal gateway 118 receives messages received from the exchange 110 from the CRBT server. It converts the signal into 120 so that it can be received and transmits it. At this time, message conversion uses ISUP protocol recommended by ITU-T.

The CRBT server 120 performs a function of providing a call waiting sound service to the incoming and outgoing mobile communication terminals 100 and 102, and inputs a sound source code to be used as the call waiting sound to the called mobile communication terminal 100, when playing the call waiting sound. Provides a website screen constructed with WML (Wireless Markup Language) including an interface for setting a playback mode, and transmits a sound source of call waiting sound data registered by the terminating mobile communication terminal 100 to the media gateway 112 through a packet network. do.

The CRBT server 120 provides a sound source of call waiting sound data to the calling mobile communication terminal 102 and receives a message for controlling the reproduction of the call waiting sound from the calling mobile communication terminal 102 through the signal gateway 118. The control of the call waiting sound is controlled based on the provided message.

In addition, when the CRBT server 120 receives a control message for entering the music listening mode from the calling mobile terminal 102, the CRBT server 120 generates charging data of the corresponding calling mobile terminal 102 until the music listening mode is terminated. Done.

The CRBT server 120 works with the subscriber database 122 and the sound source database 124 to provide call waiting sounds to the outgoing mobile communication terminal 102.

The subscriber database 122 stores personal information of subscribers subscribed to the call waiting service, for example, name, social security number, gender, address, etc., information on a mobile communication terminal's MIN, subscribed additional service, and the like. Accordingly, the CRBT server 120 obtains information (data name, path, etc.) of call waiting sound data registered by the receiving mobile communication terminal 100 by using the MIN stored in the subscriber database 122 and additional service information subscribed to.

The sound source database 124 stores call waiting sound data in various formats provided by the CRBT server 120. Call waiting sound data stored in the sound source database 124 may be classified and stored by type. Therefore, the CRBT server 120, which has obtained the name and the path of the call waiting sound data to be transmitted to the calling mobile terminal 102 through the subscriber database 122, searches the sound source database 124 and the call waiting sound data. Read and send.

The media gateway 122 receives the sound source of the call waiting sound and converts the sound into packet data so that the calling mobile terminal 102 can receive the call. The calling gateway 102 and the called mobile terminal When the call of 100 is connected, transmission of the standby sound packet data is stopped.

A process of setting information for a call waiting sound service using the system having the above configuration will be described with reference to FIG. 2. 2 is a flowchart illustrating a process of registering call waiting sound data according to the present invention.

Referring to FIG. 2, any subscriber uses his or her incoming mobile communication terminal 100 to communicate with the CRBT server 120 via the wireless base station 104, the PDSN 108, the exchange 110, and the media gateway 116. After accessing the call to the interface to register the call waiting sound data, and inputs at least one or more sound source codes using the interface provided by the CRBT server (120) (S200, S202).

The subscriber who inputs at least one sound source code selects one of a play mode, that is, a random mode, a sequential mode, and a normal mode (S204), and then selects a portion to be used as a call waiting sound among sound sources corresponding to the sound source code (S206). ).

Here, when the play mode is the random mode, the CRBT server 120 randomly selects one sound source among the sound sources registered by the subscriber whenever a call connection request is made from the originating mobile communication terminal 102 to the destination mobile communication terminal 100. When the play mode is used as the call waiting sound and the play mode is the sequential mode, each time a call connection request is made from the originating mobile communication terminal 102 to the destination mobile communication terminal 100, the sound source registered by the subscriber is sequentially selected and used as the call waiting sound. In the normal mode, when a call connection request is made from the originating mobile communication terminal 102 to the destination mobile communication terminal 100, only a specific sound source designated by the subscriber is used as the call waiting sound.

Thereafter, the CRBT server 120 stores the information set by the subscriber in the subscriber database 122 as described above (S208).

The process of providing the sound source registered in the subscriber database 122 to the outgoing mobile communication terminal 102 as a call waiting sound through the above process will be described with reference to FIGS. 3 to 4. 3 is a flowchart illustrating a call waiting sound service process according to the present invention, and FIG. 4 is a flowchart illustrating a process of controlling call waiting sound reproduction based on a control message of a call waiting sound service according to the present invention.

Referring to FIG. 3, the outgoing mobile communication terminal 102 attempts to make a call connection to the incoming mobile communication terminal 100 through the packet network (S300). That is, when the outgoing mobile terminal 102 transmits a setup message, which is a call connection request message, to the switch 110, the switch 110 uses the MIN of the outgoing mobile terminal 102 and the incoming mobile terminal 100 as an IP address. It is determined whether the incoming mobile communication terminal 100 is subscribed to the call waiting service using the converted IP address (S302).

As a result of the determination in step S302, when the terminating mobile communication terminal 100 is subscribed to the call waiting tone service, the CRBT server 120 searches the subscriber database 122 and sets the playback mode set by the subscriber of the terminating mobile communication terminal 100. Read (S304).

Thereafter, the CRBT server 120 selects a sound source stored in the subscriber database 122 based on the playback mode retrieved from the subscriber database 122, transmits the selected sound source to the calling mobile communication terminal 102 with the call waiting sound, and provides a sound source. Playback is performed (S306, S308). That is, when the playback mode is the random mode, the CRBT server 120 randomly selects one sound source from among the sound sources registered by the subscriber of the terminating mobile communication terminal 100 and sets the selected sound source as a call waiting sound. 102, when the playback mode is the sequential mode, sequentially selects sound sources registered by the subscriber of the terminating mobile communication terminal 100, and provides the selected sound source to the calling mobile communication terminal 102 with a call waiting sound, In the general mode, the subscriber of the incoming mobile communication terminal 100 randomly designates a specific sound source as a call waiting sound and provides the outgoing mobile communication terminal 102. Here, when the call waiting sound is provided to the calling mobile communication terminal 102 and played back, the CRBT server 120 transmits only the portion selected by the subscriber of the incoming mobile communication terminal 100 to use the call waiting sound of the sound source when registering the sound source. Provided to the communication terminal 102 for playback.

In this manner, while reproducing the call waiting sound, the CRBT server 120 performs a control message from the calling mobile terminal 102 through the signal gateway 118, that is, the signal gateway 118 according to a specific key operation of the calling mobile terminal 102. In step S310, it is determined whether the converted ISUP message is received.

As a result of the determination in step S310, when a control message is received from the originating mobile communication terminal 102, the CRBT server 120 controls the call waiting sound reproduction based on the control message (S312).

As described above, when the control message is received from the originating mobile communication terminal 102, the CRBT server 120 controls the call waiting sound reproduction based on the control message.

Referring to FIG. 4, first, when the CRBT server 120 receives a control message (S400), whether the control message is a control message for entering a music listening mode or not, the sound source of the mobile communication terminal 102 may be transmitted during the reproduction of the call waiting sound. The subscriber determines whether it is a control message for moving to a desired location, that is, FF, REW, or skip (S402).

As a result of the determination in step S402, when the control message is a message for entering the music listening mode, the CBRT server 120 requests the switch 110 to stop the call connection attempt between the incoming and outgoing mobile communication terminals (100, 102), accordingly The exchange 110 stops the call connection attempt between the incoming and outgoing mobile communication terminals 100 and 102 (S404).

Then, the CBRT server 120 starts to generate the charging data according to the music of the calling mobile communication terminal 102 (S406), and the sound source registered by the subscriber of the incoming mobile communication terminal 100 to the calling mobile communication terminal ( And reproduced (S408).

Thereafter, the CBRT server 120 determines whether a control message corresponding to the reproduction stop from the originating mobile communication terminal 102 is received through the signal gateway 118 (S410).

As a result of the determination in step S410, if the control message corresponding to the reproduction stop is not received, the CBRT server 120 proceeds to step S408 to continue to play the sound sources registered by the subscriber of the terminating mobile communication terminal 100, otherwise If not, the charging of the music is terminated and then the reproduction of the sound sources is stopped (S412).

As a result of the determination in step S402, if the control message is a control message corresponding to FF, REW or skip, the CBRT server 120 moves the call waiting sound being reproduced forward or backward as desired by the subscriber of the calling mobile communication terminal 102. Play or skip the call waiting sound (S414). Then, the CBRT server 120 proceeds to step S314 of Figure 3 proceeds to the next step.

As a result of the determination in step S310, when a control message is not received from the originating mobile communication terminal 102, the switch 110 determines whether a call connection related message, that is, a call connection response message, is received from the incoming mobile communication terminal 100. (S314).

As a result of the determination in step S314, when a call connection related message is received from the incoming mobile communication terminal 100, the exchange 110 transmits a CRBT connection termination message to the CRBT server 120 to disconnect the call from the CRBT server 120. By stopping the transmission of the sound source of the standby sound and transmitting a call connection message to the outgoing mobile terminal 102, a normal call path is formed between the outgoing mobile terminal 102 and the incoming mobile terminal 100.

As a result of the determination in step S314, if a call connection related message is not received from the incoming mobile communication terminal 100, the CRBT server 120 proceeds to step S308 to continuously transmit the sound source to be used as the call waiting sound to the calling mobile communication terminal 102. After transmitting and playing, perform the following steps.

On the other hand, when the incoming mobile communication terminal 100 is not subscribed to the call waiting sound service as a result of the determination in step S302, the general call waiting sound is transmitted from the outgoing mobile communication terminal 102.
