{Using method by change ring back tone into back ground music during call}

The present invention relates to a method of converting a ring back tone to a background tone during a call, and more particularly, to a caller in a variety of ring back tone and background sounds as an upgrade service of a ring back tone service provided by a mobile terminal and a wired terminal network. The present invention relates to an outgoing additional service that provides a service.

In recent years, as the number of subscribers of mobile communication terminals has exploded, various services have been provided to attract more customers.

Among these services, a service that can express a user's personality is becoming popular. For example, when a user makes a call to the other party, a ring back tone (song, sound effect) set by the other party instead of the general ring back tone (ring tone) is given to the user. , Fun sounds, etc.) is becoming popular.

The RingBackTone service currently provided by the mobile phone network provides the ringback tone sound only for the duration of the caller's attempt after the call is attempted by the called party after the call is attempted. Is not provided.

In addition, in order to receive the corresponding service, a separate service field for recognizing the corresponding service must be registered in the home location register (HLR) and the visitor location register (VLR).

Accordingly, subscribers who want to receive the service must subscribe to the service and pay an additional service fee in addition to the call charge.

The present invention has been made to solve the above-described problems, the object of the present invention is to provide a sound source set by the subscriber for the above reasons, as a ring tone until the call is connected and the caller responds to the normal call is made In this case, it provides a background sound and provides a method of converting a ring back tone to a background sound during a call, which can provide a service only in a temporary case such as birthday, promotion, admission, etc. without separately registering the service.

Another object of the present invention is to adjust the volume of the sound source to increase or decrease the volume of the sound source provided as a background sound during the call, the function of stopping the transmission of the background sound or re-send the stopped sound source, and the ability to change the sound source during the call The present invention provides a method of converting a ring back tone that can be provided to a background tone during a call and using the ring tone.

In order to achieve the above object, the present invention provides a ring back tone when a subscriber who subscribes to a background sound service of a background sound system including a background sound server and a background sound IP that is a sound source transmission device makes a call to a called party through a mobile communication network. A method of converting a) into a busy background sound;

The first step of detecting the outgoing trigger from the originating MSC and sending outgoing request message to the outgoing HLR and attaching the background sound routing number to the incoming list from the outgoing HLR and sending outgoing request response message to the outgoing MSC, The second step of translating the number and setting the call to the background sound IP, searching the sound source from the background sound IP, and sending the sound of the registered RingBackTone to the calling MSC, and the CGS or MSC connected to the background sound IP and the incoming HLR The third step of transmitting a location request message and response signal between the destination HLR and the destination MSC, a routing request message and response signal, and routing information from the CGS or MSC connected to the background sound IP are referred to as a relay call to the destination MSC. Call setup, characterized in that consisting of a fourth step of switching the sound source that is being transmitted from the background sound IP to the call connection sound to the background sound To provide a method of using the switch to the background noise during a call.

In addition, the present invention is a background sound server and a non-subscriber who has not subscribed to the background sound service of the background sound system composed of the background sound IP, which is a sound source transmission device, makes a call backing tone (RingBackTone) when making a call through a mobile communication network. In the method used to switch to;

In the first step, the non-subscriber dials the background sound routing number and the called number to receive the background sound service, sets the call to the background sound IP by translating the routing number from the originating MSC, and guides the type of sound source to be selected by the caller in the background sound IP. When the caller selects the sound source by broadcasting, the second step of transmitting the sound of the selected RingBackTone to the calling MSC, and the location request message between the CGS or MSC and the destination HLR connected to the background sound IP, or the destination HLR and the destination MSC And a third step of transmitting a response signal, a routing request message and a response signal, and setting a relay call path to the destination MSC with reference to routing information from the CGS or MSC connected to the background tone IP, and from the background tone IP to the ring back tone. Switching the ringback tone to the background tone during the call, characterized in that it comprises a fourth step of converting the sound source being transmitted to the background sound and transmitting the sound. To provide a method of use.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a background sound providing service network applied to the present invention.

The mobile terminal 10 performs a role such as authentication / security of the user, and performs signal processing and wireless transmission and reception.

The MSC (Mobile Switching Center) 20 is a complex digital exchange that provides wired communication function and mobile communication function as the most important network component device for providing a mobile communication service.

The HLR 40 is a database that stores information on the subscribers of the mobile communication service. The HLR 40 provides almost all of the subscriber data to the VLR of the MSC 20, such as when the mobile terminal 10 originates, registers a location, and receives a mobile terminal. It has a role and has the routing information necessary for the call to the mobile terminal (10).

At this time, all information and data transmission uses No.7 common line signaling method.

The gateway server 72 is a server in charge of the interface between the mobile communication network 100 and the internet network 92 and 94, and serves as a security and a firewall.

The CP (Content Provider) server 74 is in charge of the interface with the Internet networks 92 and 94, and provides sound code allocation and CP down path for each CP, statistics for each CP, and billing management.

That is, when a new sound source is registered, a sound source code for each CP is allocated and transmitted to the background sound server 62 and the background sound IP 64 so as to be distinguished.

The background sound system 60 is composed of a background sound server 62 and a background sound IP 64.

Background Peripheral IP (Intelligent Peripheral) 64 is a sound source storage and transmission device.

The background sound server 62 manages the sound source codes assigned by the subscriber DB and the CP server 74 for each subscriber.

COIS (Customer Oriented Information System) is a customer-oriented information system that is a comprehensive information system that manages customer management, billing, billing, and payment.

CDS (Customer Data Distribution System) is a system for transmitting the information requested by the customer to the exchange system (HLR, additional equipment, etc.) to prevent loss of information and maintain consistency.

Reference numeral 30 denotes a cellular gateway system (CGS), and 80 denotes a content provider as a CP.

In order to facilitate understanding of the present invention, parameters necessary for the call processing of the above-described configuration will be described.

Location Request (LOCEQ) operation is used by MSC 20 or CGS 30 to obtain incoming call processing information from HLR 40.

The call is then identified by the dialed mobile terminal address digit received by the MSC 20.

The ROUTREQ operation is used to request information to route a call to the mobile terminal 10.

Origination Request (ORIGREQ) operation is included to request call origination processing for the registered mobile terminal 10.

That is, the MSC 20 queries the HLR 40 by an originating trigger that is armed in the calling party's profile, and the HLR 40 attaches a prefix code of the corresponding service to the routing. The process of dealing with numbers.

The Origination Trigger parameter defines an originating trigger point that is currently active for a subscriber.

2 is a flowchart of a background sound provision registration procedure according to the present invention.

If the user wants to join the background sound system 60 via the COIS / CDS 50 through the Internet network 92 and 94 using the terminal, the COIS / CDS 50 creates a subscriber and the background sound to the HLR 40. Join the additional service (S20).

The HLR 40 registers the subscriber's background sound supplementary service and notifies the COIS / CDS 50 of the result (S22).

At this time, the HLR 40 activates a designated number trigger (K-digit Trigger) stored in association with the mobile terminal subscriber among the origination triggers of the corresponding subscriber profile.

The COIS / CDS 50 again creates a subscriber and subscribes the background sound supplementary service to the background sound server 62 (S24).

The background sound server 62 registers the subscriber's background sound supplementary service and notifies the COIS / CDS 50 of the result (S26).

In this way, if the service registration caller who subscribes to the background sound system 60 as a member of the background sound supplementary service accesses the background sound server 62 through the Internet network 92 and 94 and registers his own sound source in advance, the background sound server 62 allocates and stores the code of the selected sound source in association with the subscriber's telephone number.

If only the service is registered and no sound source is registered, a default sound source is provided.

In such a state, when a call is made to the incoming mobile terminal by using the calling mobile terminal, the ring back tone may be used as the background sound through the procedure as shown in FIG. 3 or FIG. 4.

3 is a flowchart illustrating a call processing flow of a background sound providing service according to a first embodiment of the present invention, in which a subscriber who subscribes to a background sound service attempts to make a call.

When the subscriber dials the telephone number of the incoming mobile terminal using the mobile terminal and makes a call connection request through the mobile communication network 100, the originating MSC 20a detects an origination trigger and dials the originating HLR 40a. An origination request (ORIGREQ: Invoke) message including dialed digits and a mobile identification number (MIN) is transmitted (S30).

The originating HLR 40a searches for a subscriber profile for the MIN upon receiving an ORIGREQ invoke, and if the background tone service is activated, sends the routing number for the background tone subscription processing, which is stored / managed in the routing number table. In addition to the TERMLIST: Termination List, an origination request return result (origreq) signal is transmitted to the originating MSC 20a (S31).

The terminator list parameter is used to provide one or more routing information to the originating MSC 20a, and consists of a routing number and dialed digits.

The originating MSC 20a receiving the originating request response signal origreq translates the routing number and sets an ISUP call to the background sound IP 64 of the background sound system.

The background sound IP 64 receiving the routing number on the ISUP separates the calling number and the called number, inquires the sound source registered by the calling subscriber to the background sound server 62, and sends the registered RingBackTone sound to the MSC ( 20a) (S32).

When the background sound server 62 inquiry result service is not registered or the calling subscriber does not register the sound source, the background sound IP 64 sends a default sound source to the calling MSC 20a.

At the same time, the background sound IP 64 attempts to set up a call to an adjacent exchange (CGS or MSC connected with the background sound IP) 110 by using an out-dialing function (S33).

The calling number is the calling party and the called number is the number dialed by the calling subscriber.

Upon receipt of the relay call processing request from the background sound IP 64, the neighbor exchange 110 transmits a Location Request (LOCREQ) message to the destination HLR 40b (S34).

The called HLR 40b transmits a routing request (ROUTREQ) message requesting routing information to the called MSC 20b according to the LOCREQ message (S35).

The destination MSC 20b allocates and provides routing information (that is, a TLDN: Temporary Local Directory Number, a routing number for distinguishing a switch), and sends a routing request response (routreq) message to the destination HLR 40b. It transmits (S36).

The called HLR 40b transmits the TLDN to the neighbor exchange 110 as a location request return result (locreq) (S37).

The adjacent switch 110, which has received the routing information TLDN as the location request response signal locreq, establishes an ISUP relay call path between the destination MSC 20b and the background sound IP 64 (S38).

Upon receiving the response message from the incoming MSC 20b, the background sound IP 64 converts the sound source being transmitted as the ring back tone to the background sound and continues to transmit the sound (S39).

In the case of the other network subscriber in step S34, since the relay call processing is requested to the other network, steps S34 to S37 are not performed.

The outgoing subscriber who subscribes to the background sound providing service through the above-described steps may convert the sound source being transmitted as the call connection tone into the background sound during the call.

4 is a call processing flowchart of a background sound providing service according to a second embodiment of the present invention, in which a non-subscriber who does not subscribe to a background sound service attempts to make a call.

When the outgoing subscriber who does not register the background sound service dials the background sound routing number and the called number (for example, the background sound subscriber routing number + the called number) to receive the background sound service, and requests a call connection through the mobile communication network 100, The originating MSC 20a receiving this sets the ISUP call to the background sound IP 64 of the background sound system 60 through number translation.

At this time, the called number may be omitted according to the marketing policy of the background sound service. In this case, the related announcement to input the called number is added in the background sound system 60.

The background sound IP 64 receiving the background sound subscriber routing number on the ISUP separates the calling number and the called number, guides and broadcasts the type of sound source to be selected by the calling subscriber, and the background sound IP when the calling subscriber selects the sound source of the background sound. 64 transmits the selected sound source to the calling party (S40).

At the same time, an ISUP call is attempted to an adjacent exchange (CGS or MSC connected with the background sound IP) 110 using an out-dialing function (S41).

The calling party number is the calling party and the called party number is the number dialed by the calling party.

If the calling party omits the called number, the announcement is added to input the called number after selecting the sound source.

Upon receiving the relay call processing request from the background sound IP 64, the neighbor exchange 110 transmits a Location Request (LOCREQ) message to the destination HLR 40b (S42).

The called HLR 40b transmits a Routing Request (ROUTREQ) message requesting routing information to the called MSC 20b according to the LOCREQ message (S43).

The destination MSC 20b allocates and provides routing information (that is, a TLDN: Temporary Local Directory Number, a routing number for distinguishing a switch), and sends a routing request response (routreq) message to the destination HLR 40b. It transmits (S44).

The called HLR 40b transmits the TLDN to the neighbor exchange 110 as a location request return result (locreq) (S45).

The adjacent exchange 100 receiving the routing information TLDN as the location request response signal locreq establishes an ISUP relay call path between the destination MSC 40b and the background sound IP 64 at step S46.

The background sound IP 64 receiving the response message from the incoming MSC 20b converts the sound source being transmitted to the ring back tone to the background sound (S47).

In the case of the other network subscriber in step S42, since the relay call processing is requested to the other network, steps S42 to S45 are not performed.

The outgoing subscriber who has not subscribed to the background sound providing service through the above steps can use the sound source being transmitted as the call connection sound as the background sound during the call.

Hereinafter, a method of adjusting a volume, stopping or retransmitting a sound, and changing a sound source of a background sound when a call connection sound is used as a background sound during a call will be described with reference to FIG. 5.

The volume of the background sound can be adjusted when using the ringback tone as the background sound during the call through the sequence of FIG. 4 as shown in FIG. 3, and the background sound IP when the calling subscriber presses a specific key in the keypad provided in the mobile terminal during the call. (64) recognizes this and lowers or raises the volume of the background sound.

For example, the # key is used to decrease the volume of the background sound during a call on the keypad, and the * key is used to increase the volume of the background sound during a call.

The volume of the background sound is divided into n (n = 2 or more) steps so that when the user presses the # key or the * key during a call, the volume of the background sound is increased or decreased by one step in the background sound IP.

In addition, when the ring back tone is used as the background sound during a call, the background sound can be stopped or retransmitted. In the case where the calling subscriber presses a specific key in the keypad provided in the mobile terminal, the background tone IP 64 Recognize this and stop or resend the background sound.

For example, when using the 0 key on the keypad, when the user presses the 0 key during a call, the background sound IP 64 stops transmitting the background sound, and again, while the background sound is stopped, the 0 key is again pressed. When pressed again, the previous transmitted background sound is transmitted again.

In addition, it is possible to change the sound source of the busy background sound in the case of using the ring back tone as the busy background sound, the background sound IP (64) recognizes when the calling subscriber presses a specific key in the keypad provided in the mobile terminal during the call To change the sound source (type) of the background sound being transmitted.

For example, as a keypad, a number (1 to 9) key is used, and when the user presses any number n (1 to 9) key while the background sound is being transmitted during a call, the user plays the background sound server 62. The background sound IP 64 transmits the other nth background sound stored in the background sound.

At this time, if there is no nth sound source stored by the user or the same as the sound source currently being transmitted, the background sound currently being transmitted is continuously transmitted.

The method of changing the background sound can be provided only when the background sound service is subscribed (only in the case of FIG. 3).

As described above, when the caller makes a normal call by answering the sound source provided as the ring back tone until the call is connected, the call is provided as the background sound and the service is only provided for temporary occasions such as birthdays, promotions, admissions, etc. Can provide.

In addition, it is possible to provide a subscriber with a volume adjustment function for increasing or decreasing the volume of a sound source provided as a background sound during a call, a function for stopping the transmission of a background sound or resending the stopped sound again, and changing a sound source during a call.

As described above, as an upgrade concept of the existing RingBackTone service, a subscriber may select a sound source selected during a call.

In addition, it is possible to provide services using only additional network elements, which can be applied to any type of core network (including wired telephone network) such as IMT-2000 network as well as existing network (IS-95 A / B / C). It is possible.

It can also provide sound recordings to non-subscribers, providing a catalyst for subscribers who wish to celebrate a specific anniversary (birthday, promotion, admission, graduation, 100th day meeting, etc.) or require an event call, such as an atmosphere (confession of love, proposal). In charge.

In addition, the activation of the service can contribute to the development of content such as records and content providers (CPs).
