System and method for providing ring back tone service {SYSTEM AND METHOD FOR PROVIDING RING BACK TONE SERVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for providing a ring back tone service. Specifically, when a caller makes a call to a receiver's mobile phone, the caller plays a sound source set by the receiver instead of the conventional ring back tone. A system and method for providing a ring back tone service for periodically updating and reproducing different sound sources (contents).

The ring tone that is heard by the receiver when making a call such as a mobile phone serves as a good medium for exposing his or her image or personality to the caller along with a voice mail announcement. Accordingly, a call connection service for reproducing a specific sound source selected by a user instead of a one-tone uniform machine tone during a call connection has been proposed and widely used.

The conventional ring back tone service is that when a mobile phone holder (receiver) selects a sound source (content) to apply for and use the service with a mobile carrier, when another person (caller) makes a call to the receiver, the set sound is played instead of the general ring back tone. It is a service. Examples of the conventional ring back tone service include a coloring service of SK Telecom and a ring-to-ring service (Ring2Me, Ring2You) of KTF.

On the other hand, such a ring-tone service is also applied to advertising, mobile phone users to select / use a specific company's promotional announcements, such as their own ring back tone and receive a certain fee from the corresponding advertising company or to select their own promotional announcements It is applied to the furnace.

However, the conventional RBT service has a limitation that uniformly reproduces the sound source selected by the receiver regardless of the caller. It provides a variety of services (caller ID, ringtone setting, etc.) depending on the caller's phone number, and even a service (for example, SK Telecom's lettering service) that can deliver specific texts to the called party. Given the reality that the user had a lot of inconvenience. In particular, there is a problem that does not meet the needs of users who want to shed their personality and use differentiated services to lovers, friends, family.

On the other hand, the conventional ring back tone has a problem that the same sound source is provided as the ring back tone as long as the receiver does not directly change the ring back tone, so that the caller can feel bored by repeated calls.

The present invention has been presented to solve the above problems, an object of the present invention is to identify the caller through the phone number of the caller calling the user's (recipient) mobile phone to set the receiver in advance for the caller instead of a ring back tone The present invention provides a system and method for providing a ring back tone service which can provide different ring back tones for each caller or time zone calling the same receiver by periodically updating and playing a specific content.

Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

1 is a block diagram of a system for providing a ring back tone service according to the present invention. As shown in FIG. 1, the configuration of the system for providing a ring back tone service according to the present invention is selected by a receiver mobile phone 10 and a receiver provided by a user (receiver) who applies for and uses the ring back tone service according to the present invention. Caller terminal 20 provided by the caller receiving the ring-tone service according to the present invention when the call to the receiver, after receiving and storing the content requested by the receiver to play the stored content when the caller calls the receiver The mobile communication company system 30 and the content providing system 40 for generating and transmitting the content requested by the receiver.

Unlike the conventional ring back tone service (coloring, ring-to-service, etc.), the ring back tone service according to the present invention identifies a caller by using the caller's telephone number as a key when a specific caller (registered caller) makes a call to the receiver's mobile phone. After that, it means a service that plays a specific content set by the receiver for the caller instead of the ring back tone. Hereinafter, a service providing a differential ring tone for each caller is called a 'telephone ring tone service'. For example, the content may be a case of playing general music or providing specific information. In particular, in the case of providing specific information, if the content is today's fortune, 'XX's today's fortune is provided in the form .....'. In addition, the receiver may provide contents to be delivered to the sender as content, in which case the receiver may input text and convert and play the voice, or the receiver may record and play the voice directly. On the other hand, when an unspecified caller who is not registered by the receiver makes a call, a conventional call ring tone or a separate content (music, etc.) set by the receiver is played.

The receiver cellular phone 10 according to the present invention is a terminal for using a mobile communication service provided by the mobile communication company system 30, and is a mobile phone used by a user who applies for a ring back tone service, that is, a receiver. In addition, the caller terminal 20 according to the present invention is a terminal capable of specifying a caller's telephone number as a wired or wireless telephone of a caller who makes a call to a receiver's cellular phone. On the other hand, if the caller terminal 20 is a general mobile phone and the caller uses the ring back tone service, the caller terminal will be the receiver mobile phone 10.

The receiver accesses the telecommunication company system 30 through the wireless Internet or the general Internet network, applies for a ring tone service, registers each caller's telephone number and basic information (name, etc.) to receive the ring tone service, and sends each caller. Select the content provided by the star. Such a ring back tone service registration process may also be performed through ARS.

When the caller makes a call to the receiver cellular phone 10 by the caller terminal 20 having the designated telephone number, the caller receives the contents set by the receiver instead of the conventional ring back tone. On the other hand, the provided content may require additional information such as the sender's personal information (for example, the caller's fortune, the sender's biorhythm, the provision of specific securities information, etc.). Upon request, it connects to the mobile carrier system and inputs additional information. However, if it is not necessary to receive additional information from the sender due to the nature of the content, the receiver may request additional information. For example, if the content counts the number of days that lovers have met, the recipient may receive the date of meeting the registered sender.

The mobile telecommunication company system 30 according to the present invention is a system for providing a ring tone service with a mobile communication service (mobile phone service, wireless Internet service, etc.) to the receiver. Hereinafter, a description of the mobile communication service inherent in the mobile communication company except for the ringback tone service, which is the subject of the present invention, will be omitted. The mobile telecommunication company system 30 includes a mobile telecommunication company server 32 providing a ring back tone service and a customer information database 34 storing information and contents of the recipient and the sender.

The mobile telecommunication company server 32 according to the present invention receives a request for using a ring back tone service and a caller's registration and caller's content selection from a receiver, requests and receives the selected content from the content providing system 40, and receives the caller. When playing the call to the receiver's mobile phone 10 will play the selected content instead of the ring back tone.

The mobile telecommunication company server 32 includes an input processing module, a content processing module, and a content playing module for processing a ring back tone service. The input processing module is a module for processing inputs of the receiver and the sender, such as application of a ring back tone service, caller registration (enter phone number and basic information), content selection, and input of additional information of the caller. The content processing module is a module for transmitting the basic information and additional information of the sender to the content providing system 30 and a request for the selected content, and storing the periodically transmitted contents in the customer information database 34. In addition, the content playback module is a module for identifying the receiver and the caller to load and play the selected content when the caller makes a call to the receiver's cellular phone 10. Each module of the mobile communication company server 32 preferably uses the telephone number of the receiver cellular phone 10 and the telephone number of the caller terminal 20 in distinguishing and identifying the receiver and the caller. For example, when a caller makes a call to a recipient's mobile phone using the calling party's terminal, the calling party's phone number is the identification code to identify the recipient and the calling party's phone number is the identification code to identify the caller. Used.

The customer information database 34 according to the present invention stores and manages the information of the receiver and the caller using the ring back tone service and the content of each caller selected by the receiver and transmitted from the content providing system 40. The stored information of the receiver includes personal information of the receiver and an identification code (recipient identification code, for example, a telephone number), and may store a flag indicating whether to use authentication information and a ring back tone service. The caller information includes the caller's terminal 20 identification code (caller identification code, for example, a phone number) and the caller's basic information (name, etc.) registered by the receiver, and the content selected by the receiver needs additional information from the caller. If you do (for example, fortune-telling, biorhythm, securities information, etc.) should include additional information of the sender (date of birth date, preferred securities item identification code, etc.). In practice, a field for recording each additional information in the table may be configured, and then a null value or an arbitrary identification value may be stored in the corresponding field for the caller who does not need the additional information. In this case, when using a separate identification value (ID) other than the telephone number as the receiver identification code and the caller identification code, it is preferable to have a mapping table for mapping each identification value and the telephone numbers of the receiver and the caller.

On the other hand, the content stored in the customer information database 34 is a content used in the ring back tone service, each recipient is selected for each caller and received from the content providing system 40. As described above, since each content is updated periodically (daily or predetermined time) and received from the content providing system, the customer information database 34 updates the new content periodically received. In addition, the customer information database 34 stores an identification code (content identification code) for identifying each content, the content identification code is to distinguish the type of content (music, fortune, biorhythm, etc.) A unique value that identifies the recipient and the sender to be provided. The content identification code is preferably generated by including a content type code for identifying a content type, an identification code of a receiver and a sender, and if a random identification value (ID) or a serial number is used as the content identification code. It is preferable to have a mapping table for mapping the identification value and the content type code, and the identification code of the receiver and the sender. The content identification code is used to identify the content transmitted and received between the mobile communication company system 20 and the content providing system 30.

In addition, the customer information database 34 preferably includes a content information table for storing basic information about the content. Basic information on the content includes the content provided in the ring back tone service, the content type code of each content, a flag indicating whether additional information is required for each content, and additional information items required.

The content providing system 40 according to the present invention is a system for receiving a content providing request from the mobile communication company system 30 and generating and transmitting the requested content, which includes a content providing server 42 and a content database 44. .

The content providing server 42 according to the present invention receives a request for providing content for each sender selected by the receiver from the mobile communication company server 32, and generates and transmits the received content. In this case, when the content is content that does not need periodic generation (for example, music), the content is not regenerated or updated unless there is a separate request from the mobile communication company server 32. However, if the content is an attribute that needs to be updated periodically, such as fortune telling or biorhythm, the content providing server 42 may generate and transmit new content every day. In addition, when it is necessary to update the content by a predetermined time unit, such as securities information, new content is generated and transmitted at a predetermined time interval. Such periodicity and update interval of the content may be received together when receiving the content providing request from the mobile carrier server 32, but when selecting the content to provide to the ring-tone service, according to the property of the content in advance and set accordingly It is desirable to automatically generate / update it.

As described above, when the content is transmitted and received between the mobile telecommunication company server 32 and the content providing server 42, the content is identified using a content identification code. For this purpose, the mobile telecommunication company server and the content providing server have the same content identification code. Use. That is, when the mobile communication company server 32 requests a specific content, the content providing server 42 can identify the content to be generated by transmitting the content identification code together. As described above, the content identification code includes the type code of the content and the identification code of the receiver and the sender. In this case, the content providing server recognizes the content to be generated through the content type code among the content identification codes. In addition, the content providing server 42 transmits the content identification code together when transmitting the generated / updated content, so that the mobile telecommunication company server 32 identifies and stores the received content in the customer information database 34. In this case, the mobile telecommunication company server 32 classifies and stores the content received through the identification code of the receiver and the sender included in the content identification code.

The content database 44 according to the present invention stores the content request details received from the mobile communication company server 32 and the respective content generated by the content providing server 42 and the content identification code. The content request history includes an identification code of the requested content and may include a request date and time. In addition, the content database 44 includes a content attribute table that stores preset content attributes for each content provided to the ring back tone service. The content property includes a flag indicating update periodicity (periodic update) of each content and update period (update interval). In order to extract data from the content attribute table, it is preferable to use a content type code as a key.

Configuration and operation of each component of the present invention will be more clearly understood through the description of Figures 2 and 3 for the process of providing and changing the ring back tone service.

2 is a flowchart illustrating a process of providing a ring back tone service according to the present invention. As shown in Figure 2, the process of providing a ring back tone service according to the present invention has the following flow.

First, the receiver connects to the mobile communication company system 30 through the receiver cellular phone 10 and applies for a ring back tone service (ST200). The input processing module of the mobile telecommunication company server 32 requests the selection of the caller's telephone number and the content for each caller to use the ring back tone service and receives it from the receiver (ST205, ST210). At this time, the basic information (name, etc.) of the sender necessary for providing the content is input as described above. On the other hand, the application of the ring-tone service may be made through the recipient mobile phone 10 and the wireless Internet, may be made through a personal computer and a general Internet network or through an ARS or call center. Hereinafter, a description will be given of the process proceeding through the receiver mobile phone and the wireless Internet.

The input processing module of the mobile communication company server 32 requests the registered sender to input additional information necessary for providing contents when the content selected by the receiver requires input of additional information of the sender (date of birth, preferred stock item, etc.). And receive it from the caller (ST215, ST220). Whether or not additional information is required is determined based on the information stored in the content information table of the customer information database 34, and extracted using the type code of the content selected by the receiver as a key. In addition, the request and input of the additional information may request the caller terminal 20 to enter the necessary information after inducing a connection to the mobile communication company system 30 through SMS. In this case, of course, you can also use a call center.

The input processing module of the mobile communication company server 32 stores the receiver identification code (telephone number), the registered caller identification code (telephone number) and basic information in each field of the customer information database 34, and stores the contents selected by the receiver. Generate and store an identification code. In addition, if additional caller information is input to be stored together (ST225). The content identification code is generated by combining the type code, the receiver identification code, and the sender identification code of the content selected by the receiver.

The content processing module of the mobile communication company server 32 extracts the sender's basic information (name, etc.), additional information, and identification code of the content from the customer information database 34, and transmits it to the content providing system 40, and the content providing server. 42 stores this in the content database 44 (ST230, ST235).

The content providing server 42 identifies the content to be generated through the content type code among the content identification codes, and sets the content property (update periodicity, update cycle, etc.) from the content property table of the content database 44 using the content type code as a key. The extracted content is generated by recognizing whether the corresponding content is periodically updated and the update period (ST240). The generated content is stored in the content database 44 and transmitted to the mobile communication company system 30 along with the content identification code.

Specifically, when the content is a kind that should be generated periodically, the content providing server 42 sets a counter according to the update period of the content property. The counter generates a content update signal for each update period, and the content providing server detects this and loads the most recently generated content from the content database 44 and updates it.

On the other hand, the content is generated and provided as a sound source that is inserted in place of the ring-tone sound, and includes music or human voice for delivering specific information. In particular, in the latter case, content is generated by generating information to be delivered in advance and converting it into a human voice. For example, if the content is today's horoscope, today's fortune information (text) is generated through the caller's date of birth and then converted into a human voice. At this time, if the voice to be converted to the voice of a specific person (for example entertainer) may be selected from the receiver of course. Since a technology for converting information such as text into voice is already known, a detailed description thereof will be omitted.

In order to transmit the generated content to the mobile communication company system, it is preferable to use a late night time zone with a small amount of call in order to avoid congestion of the network.

The content processing module of the mobile telecommunication company server 32 stores the content periodically received from the content providing server 42 in the customer information database 34 (ST245). Specifically, the receiver and the sender are identified through the receiver and the sender identification code of the content identification code received with the content and stored in the corresponding field of the customer information database.

When the caller makes a call to the receiver mobile phone 10 using the caller terminal 20 having the phone number registered in the ring back tone service, the phone number of the receiver and the caller's phone number entered are transmitted to the mobile communication company system 30. (ST250). The content reproducing module of the mobile communication company server 32 extracts the content from the customer information database 34 using the transmitted recipient phone number and the sender phone number as a key, and inserts and reproduces the extracted content as the ring back tone (ST255, ST260). .

3 is a flowchart illustrating a process of changing a ring back tone service according to the present invention. As shown in Figure 3, the process of changing the ring-tone service according to the present invention has the following flow.

The receiver connects to the mobile communication company system 30 and makes an application according to the change type of the ring back tone service. If the user wants to terminate the RBT service, the service provider transmits a request to the mobile communication company system 30, and the mobile communication company server 32 terminates the service after authenticating the receiver (ST300 to ST310). Specifically, the mobile telecommunication company server 32 is made by displaying the service change list on the screen of the receiver cellular phone 10 and the like and selecting the service cancellation item by the receiver. When the service termination is completed, the mobile telecommunication company server 32 deletes information and contents of the receiver and the caller for the ring back tone service stored in the customer information database 34. In addition, the content providing system 40 requests to stop the update of the content, the content providing server 42, the sender information (basic information, additional information) and the content details (content identification code, generated content of the content database 44) Etc.) are deleted (ST315, ST320). In this case, the carrier server 32 transmits a content identification code together with the update stop request, and the content providing server finds and deletes data in which the content type code of the content identification code, the identification code of the receiver and the sender all match the content database. Done.

If the receiver wants to change the content of the ring back tone service, the mobile telecommunication company server 32 displays a list of callers registered by the receiver and selected content for each caller (ST325, ST330).

When the receiver wants to change the sender's information, the receiver selects the sender to be changed and inputs the changed contents (telephone number, name, etc.) (ST335 and ST340). The input processing module of the mobile communication company server 32 stores the changed contents in the customer information database (ST345). At this time, if the receiver changes the basic information such as the name of the sender, the content processing module of the mobile communication company server 32 transmits the changed basic information and the content identification code to the content providing server 42, the content providing server (content database ( Update the corresponding field in 44). In addition, when the caller's telephone number is changed, the content identification code is also changed, so that a new content identification code is generated and updated in the customer information database, and the content providing code and the new content identification code are transmitted to the content providing server.

In addition, if you want to change the content for a specific caller, select the sender to change and input the content to change (ST350, ST355). At this time, if the changed content needs additional information of the sender, the input processing module of the mobile communication company server 32 receives and requests additional information from the sender and stores it (ST360, ST365). The content processing module of the mobile communication company server transmits the change history of the content, that is, the content identification code before the change and the newly assigned content identification code, and if there is additional sender information, it is transmitted together (ST370). The content providing server 42 finds the corresponding item in the content database 44 through the content identification code before change, and stores the new content identification code and the sender additional information (ST375). At this time, the content providing server 42 can extract the attributes (update periodicity and update cycle) of the corresponding content by using the content type code of the new content identification code as a key. The content providing server 42 periodically generates and transmits the changed content (ST380).

In addition to the above description, the content may include various types such as deletion of a specific registered sender and addition of a sender. In this case, since the process is similar to the above-described process, a detailed description thereof will be omitted.

In the above description, an embodiment in which the receiver applies for and changes the ring back tone service to the mobile communication company system 30 has been described. Alternatively, the content providing system 40 may apply and change the ring back tone service. In this case, the receiver accesses the content providing system 40 to apply for a direct ring tone service, and the mobile communication company system only needs to periodically receive and play the content from the content providing system.

In addition, the above description has been given of an embodiment in which the content is reproduced by using a ring tone when the receiver uses a mobile phone. However, it can be easily applied to a general landline phone.

On the other hand, as a modification of the present invention without providing a content for each caller may provide content that is periodically updated (for example, the fortune of the receiver, etc.) to the unspecified sender, may be set to different content provided for each time zone have. Since the modification is easily understood based on the above description, detailed description thereof will be omitted.

As described above, the system and method for providing a ring back tone service according to the present invention reproduces the selected content when the caller who previously registered and selects the content calls the receiver, when the caller makes a call over a predetermined period. There is a remarkable effect that can provide different ring back tones for each.

In other words, the system and method for providing a ring back tone service according to the present invention,

First, since the receiver can freely select the contents to be provided to the sender, it is possible not only to provide a characteristic / differentiated service for each user, but also to improve the satisfaction of the service by updating the contents on a daily or fixed time basis.

Secondly, by identifying the recipient and the sender using the phone number, there is no need for a separate module to identify the recipient and the sender and improve processing efficiency.

Thirdly, the mobile carrier system only needs to store and play periodically updated content, so that the processing delay due to the overload of the system is not only prevented, but also the network can be prevented by transmitting the content during a time when the call volume is low. Can,

Fourth, because the uniform content identification code between the mobile carrier system and the content providing system is used, there is no need for a separate module for content identification, and there is no fear of a recognition error of the content.

Fifth, the content properties such as the periodic characteristics of the preset content is used to generate the content, which enables consistent generation of the content.

Finally, a variety of applications can be implemented, such as application to a regular landline phone and converting content provided for each time zone.

While the preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only, and it is understood that various changes and modifications may be made without departing from the spirit and scope of the following claims. Should be done.
