The mobile terminals 110, 112, and 114 are terminals capable of voice call and data communication with the other party through the mobile communication network. According to an embodiment of the present invention, the calling terminal 110 receives and outputs a ring back tone set by the called party while the call is connected during the call to the called terminal 112 with a call attempt, and then by the caller. If there is a key input for changing the ring back tone, the terminal transmits a ring back tone change request wirelessly. Here, the call attempt means that a key input having the same function as the call button of the calling terminal 110 is pressed or the call button is pressed is performed.

Here, the method for requesting a ring back tone change when a call is waiting is performed by pressing a specific button, for example, a "#" or "*" button, while the caller listens to the ring back tone of the called party. You will be asked.

On the other hand, the mobile terminal 110 performs the function of receiving the ring back tone data transmitted when the call is connected to the speaker.

Here, the ring back tone service according to the embodiment of the present invention does not transmit the ring back tone data stored in the calling terminal 110 to the speaker but instead receives the ring back tone data received by the calling terminal 110 and sends it to the speaker. It is a service. To this end, an embodiment of the present invention uses a data transmission technology capable of transmitting the ring back tone data transmitted to the speaker at the same time, preferably a streaming technology.

Streaming technology is a technology that plays back audio files, video files, etc. in real time on the Internet. In the conventional file playback method, since all files are first downloaded to the hard disk and then played, the file is not played at all until the download is completed. . However, in streaming technology, when the first small size of a file to be sent to the receiver is transmitted, the first part of the file is transmitted, while the remaining part is continuously received and simultaneously played. In addition, in the streaming technology, a file transmitted from a transmitting side to a receiving side is not stored at the receiving side and is immediately deleted whenever a portion of reproduction is finished.

On the other hand, the mobile terminals 110, 112 and 114 according to an embodiment of the present invention is a PDA (Personal Digital Assistant), cellular phone, PCS (Personal Communication Service) phone, GSM (Global System for Mobile) phone, W-CDMA ( Wideband CDMA) phones, CDMA-2000 phones, Mobile Broadband System (MBS) phones and the like. Here, MBS phone refers to a mobile phone to be used in the fourth generation system currently being discussed.

The mobile switching centers 120 to 122 perform basic and additional service processing, incoming and outgoing call processing of subscribers, location registration and handoff procedure processing, interworking with other networks, and the like. The mobile switching center (120-122) of the IS-95 A / B / C system operates an access switching subsystem (ASS) that performs distributed call processing, an INS (interconnection network subsystem) that performs centralized call processing, and operation. And a subsystem such as a Central Control Subsystem (CCS) in charge of the centralization of maintenance, and a Location Registration Subsystem (LRS) that performs storage and management of information on mobile subscribers.

In addition, mobile switching centers (120 to 122) for 3rd and 4th generations include an Asynchronous Transfer Mode (ATM) switch (not shown), which increases transmission speed and efficiency of line usage by cell-by-cell packet transmission. Let's do it.

Meanwhile, although not shown in the figure, a mobile communication network (Telephony network) includes a base station transmitter and a base station controller, and supports both synchronous and asynchronous. Here, in the case of synchronous, the base station transmitter will be a base transceiver station (BTS), the base station controller will be a base station controller (BSC), in the case of asynchronous, the base station transmitter is a Node-B (Node Base Station), and the base station controller is an RNC ( Radio Network Controller. Of course, the mobile communication network according to the embodiment of the present invention is not limited thereto, and may include a GSM network other than a CDMA network and an access network of a fourth generation mobile communication system to be implemented in the future.

The base station transmitter receives a call request signal from the mobile terminals 110, 112, and 114 through a traffic channel of the signal channel, and transmits the received call request signal to the base station controller. In addition, the base station transmitter is a network endpoint device that is directly connected to the mobile terminal 110 by performing baseband signal processing, wired and wireless conversion, and transmission and reception of wireless signals.

The base station controller controls base station transmitters, and assigns and releases radio channels for mobile terminals 110, 112, and 114, transmit power control of mobile stations 110, 112, and 114, and base station transmitters, and soft handoff between cells. And hard handoff determination, transcoding and vocoding, global positioning system (GPS) clock distribution, and operation and maintenance functions for the base station. The base station controller forwards the call request signal received through the base station transmitter to the mobile switching centers 120-122.

The SMC 130 converts a text message created by the calling terminal 110 into a short message according to a request of the short message of the caller and transmits the short message to the called terminal 112.

The HLR 140 receives the location information of the terminal from the visitor location register (VLR) and performs functions such as registration recognition, registration deletion, and location verification. In addition, the profile information of the mobile terminals 110, 112, and 114 is stored in the HLR 140. Here, the profile information refers to a mobile identification number (MIN), an electronic serial number (ESN), and subscribed mobile communication service information of the mobile terminals 110, 112, and 114. The visitor location register (VLR) transmits the subscriber data from the mobile switching center 120 in the case of the location information of the visited subscriber whose location registration is performed, in the case of the call from the calling terminal 110, the incoming call to the called terminal 112, and the like. Receive and save.

COIS 150 is a customer-oriented information system designed, built, and operated by SK Telecom. It is a comprehensive information system that manages customer management, billing, billing, and payment.

The coloring server 162 manages a subscriber's database (DB) and coloring sound source codes registered for each subscriber, and provides a CRC (Color Ring Change) service function.

The coloring IP 164 is an intelligent device (Intelligent Peripheral) that functions to store or transmit a coloring (call ring tone) sound source and transmits a coloring sound source through a No.7 call connection with an exchange.

The GW server 172 is responsible for the interface between the internal network and the external Internet network, and is responsible for security (Security) and firewall (Firewall) functions.

The CP server 174 interfaces with an external Internet network and a wireless application protocol (WAP), and performs coloring role code allocation and coloring down paths for each content provider (CP), statistics for each CP, and billing. That is, when a new coloring registration is assigned, the coloring sound source code for each CP is transmitted to the coloring server 162 and the coloring IP 164 to be distinguished.

The content provider 180 is a company that provides content such as an image or a video.

The wired / wireless internet servers 190 to 192 are connected to the CP server 174 by Web or WAP to provide the mobile terminal 110 to 114 with contents and various types of wires and wirelessly.

2 is a flowchart illustrating a method for changing a ring back tone service in a ring back tone providing state according to an embodiment of the present invention.

When the caller is located at a certain place while carrying the mobile terminal 110, the mobile terminal 110 performs location registration for the base station that currently manages the area where the mobile terminal 110 is located. This location registration process is a well-known technique known in the art, so the detailed process is omitted.

In the state where the mobile terminal 110 has completed the location registration with respect to the base station, the mobile terminal 110 is set in the telephone call mode so as to be able to make a normal call or to make an incoming call.

The caller requests the call by inputting the called party's phone number by operating the mobile terminal 110 for a voice call. Accordingly, the call connection request signal is transmitted from the mobile terminal 110 to the originating MSC 120 via the base station. At this time, the call connection request signal includes the telephone number of the caller and the telephone number of the called party.

The originating mobile switching center 120 transmits an incoming information request message (LOCREQ: Location Request) to the HLR 140 based on the call connection request signal (S202).

The HLR 140 transmits a routing information request message (ROUREQ: Routing Request) to the terminating MSC 122 to obtain a Temporary Local Directory Number (TLDN) (S204). The TLDN is a telephone number temporarily assigned by another switching station for call routing when the routing number terminal for call delivery in a mobile telephone exchange is located at another switching center outside the home switching center.

The destination mobile switching center 122 allocates a TLDN to the routing information request message and transmits a routing information response message (roureq [TLDN]: Routing Request Return Result) to the HLR 140 (S206).

When the HLR 140 receives the routing information response message (roureq [TLDN]) from the destination mobile switching center 122, the calling information response message (locreq [TLDN]) including the TLDN to the calling mobile switching center 120: Location Request Return Result) is returned (S208).

The originating mobile switching center 120 analyzes the TLDN and transmits a call setup message (ISUP_IAM) to the called mobile switching center 122 based on the received incoming information response message (locreq [TLDN]) to establish a call ( S210).

If the ring back tone service field received in the location registration step is activated, the called party mobile switching center 122 performs paging to the called mobile terminal 112 and uses Color Ring Routing Digits (Routing Digits for Coloring IP). The call is set to the coloring IP 164 (S212). At this time, when the call is set to the coloring IP 164, the Called Party Number parameter of ISUP_IAM is set to "Routing Digits for coloring IP + called party's MDN."

When the coloring IP 164 receives the ISUP_IAM from the called mobile switching center 122, the coloring IP 164 returns the ISUP_ACM to the called mobile switching center 122, and requests the coloring server 162 of the subscriber's ring tone tone code (S214). .

The coloring server 162 analyzes the MDN (called party number) received from the coloring IP 164, returns the ring back tone source code set by the subscriber to the coloring IP 164, and responds to the ring back tone sound code request ( S216). At this time, when analyzing the MDN (called number) in the coloring server 162, if the ring back tone service is not registered or if the MDN (called number) from the coloring IP 164 is not received as the default (Default) Returns the set ring back tone source code.

The coloring IP 164 receiving the ring back tone source code from the coloring server 162 transmits the caller ring tone sound corresponding to the caller to the caller's mobile terminal 110 over the set call (S218).

The caller hears the called party's ring tone sound source received by the mobile terminal 110 through the mobile terminal 110 as an audible sound.

When the caller wants to convert the called party's ring back tone to the ringback tone registered by the caller while receiving the ring back tone service, the caller enters a specific digit, for example, "#" or "*", and the call is in service. Release the connection sound or request a change (S220).

Coloring IP 164 receiving a specific digit from the mobile terminal 110 analyzes it and includes a ringing tone change (Color Ring Change) including a MIN (calling number) and a ringing tone source code being sent. 162) (S222).

The coloring server 162, which is requested to change the ring back tone from the coloring IP 164, transmits the sound source code of the ring back tone registered by the caller to the coloring IP 164 (S224). In this case, the coloring server 162 analyzes the calling number and does not provide a corresponding function in the case of another subscriber. In addition, when the calling subscriber is a mobile network subscriber or a ring back tone service, a release message is transmitted to the coloring IP 164.

The coloring IP 164 receiving the changed ring back tone source code from the coloring server 162 transmits the sound source corresponding to the changed ring back tone to the caller's mobile terminal 110 (S226).

On the other hand, if the ring back tone service is not registered and receives a release message from the coloring server 162, the coloring IP 164 transmits the release message to the called-side mobile switching center 122. Receiving the release message from the coloring IP 164, the destination mobile switching center 122 releases the call connected to the coloring IP 164 and ringback tone basically provided by the mobile switching center (MSC) to the caller's mobile terminal 110. (Ring Back Tone) is transmitted to the mobile terminal (110).

As described above, according to the present invention, when the caller enters the called party number and changes the called party's coloring to his own coloring while listening to the coloring set by the called party, or the ring back tone service is not registered. A method and system for changing a ring back tone service in a ring back tone providing state for releasing a call connected with a coloring IP and providing a ringback tone to a caller can be realized.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.

The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, it is possible to release the call ring tone set by the called party in real time, and change the call ring tone source of the caller.

From the perspective of the service provider, the caller may be encouraged to set the called party's ring back tone as his / her own ring back tone while the caller is making a call, so that the profit from the increase in the use of the corresponding service can be expected.
