Description

Method and apparatus of transmitting personal information in subscriber-based ringback tone service

TECHNICAL FIELD

The present invention relates to a method and apparatus for a subscriber-based ringback tone service of providing a specific sound, which a called subscriber has chosen as a ringback tone, in order to improve the existing uniform ringback tone service. More specifically, the present invention relates to a method and aparatus for the called subscriber to send his own personal information as a sound by various ways or to send the personal information along with a pre-set ringback tone replacement sound by various ways.

BACKGROUND ART

In general, when a caller calls another through an existing mobile communication network, a terminating exchanger of the called subscriber provides the caller with a uniform ringback tone. Since the ringback tone is the same all the time, the caller cannot identify the called individual before the called individual answers. Furthermore, the uniform ringback tone cannot satisfy various subscribers' needs to reveal their individuality. A method was proposed to send various ad sound messages to a caller instead of such uniform ringback tone. However, such an ad sound message is chosen unilaterally by a network operating enterprise. If a caller heard such a unilateral ad sound, he could talk over a mobile telephone with the called individual for a limited time for free. However, the method in which the ad sound is provided instead of the conventional ringback tone still has the aforementioned drawbacks. That is, a caller cannot identify a called individual before the called individual answers and the uniform ringback tone cannot satisfy various subscribers' needs to reveal thier individuality. In Korean Patent Application No. 2000-10006 dated February 25, 2002, the applicant of the present application had disclosed a method and apparatus for providing a subscriber-based ringback tone service. This application provides a caller with a specific sound registered or chosen by a called subscriber instead of a conventional ringback tone, whereby a sound replacing the ringback tone which fits to the called subscriber's character can be provided with the caller while the caller can identify a called individual before the called individual answers, and the caller can determine the existence of a wrong connection before a called individual makes a response. However, although the conventional art has an advantage in that the individuality of the called subscriber can be revealed by providing the caller with a replacement sound such as music instead of the ringback tone, it has a problem in that a caller cannot determine a wrong connection only by the ringback tone replacement sound of the called subscriber. In addition, the called subscriber cannot send the caller the information which the called subscriber designates to be sent, since a common sound resource is used for the replacement sound so other subscribers can use the identical replacement sound.

DISCLOSURE OF THE INVENTION The object of the present invention is to provide a method and apparatus for transmitting personal information in a subscriber-based ringback tone service which can transmit the personal information representing a called subscriber by a ringback tone replacement sound. According to a first aspect of the present invention, the method for transmitting personal information in a subscriber-based ringback tone service comprises the steps of: a home location register providing a call-terminating exchanger with first information on whether or not a registered ringback tone previously set in the home location register is to be replaced and second information for routing to sound providing means when a calling terminal is registered in the call-tenninating exchanger; the call-terminating exchanger requesting a call connection to the sound providing means based on the first and the second information if the calling terminal requests a call to a called terminal; and the sound providing means call-connecting to the calling terminal, detecting a specific sound set corresponding to the called terminal, and providing the calling terminal with the detected specific sound if the call connection is received, wherein the specific sound is generated by combining a subscriber information sound for specific information, which can identify the called subscriber or can represent the subscriber's character, with a common ringback tone replacement sound set by the called subscriber.

PREFERRED EMBODIMENT OF THE INVENTION

Hereinafter, some preferred embodiments of a method and apparatus for transmitting personal information in a subscriber-based ringback tone service will be described with reference to the accompanying drawings. Fig. 1 is a schematic diagram showing an apparatus for transmitting personal information in a subscriber-based ringback tone service according to an embodiment of the present invention. Referring to Fig. 1, the apparatus for transmitting personal information in the subscriber-based ringback tone service according to the present invention comprises a home location register 10, exchangers(O_MSC/VLR, TJMSC/VLR) 31 and 32, a sound providing apparatus(IP; Intelligent Peripheral) 50, a sound storage managing server(IP

Server) 70, a subscriber database 80, and a web server 100. The exchangers 31 and 32 communicate with the home location register 10 via No. 7 network 2 based on a signalling transfer protocol(STP) 20. The sound providing apparatus 50 is communicatively connected to the No. 7 network 20 to communicate with the exchangers 31 and 32 via a gateway (CGS) 40. The sound storage managing server 70 communicates data with the sound providing apparatus 50 via the Internet 60. The subscriber database 80 is communicatively connected to the home location register 10 via the Internet 60. The web server 100 is communicatively connected with the sound providing apparatus 50 and with the sound providing control server 70 via the Internet 60. The home location register 10 has all functions of an existing network element and stores the first information about whether or not each subscriber subscribes a personal ringback tone service and the second information for routing a call to the sound providing apparatus 50 in each subscriber's profile. Preferably, the first and the second information is stored in the subscriber's profile as supplementary service subscription information. The exchangers 31 and 32 have all functions of existing network elements.

When the location information of the called subscriber (or called terminal) is registered, the exchangers 31 and 32 store the first and second information provided from the home location register 10 according to the present invention. If a call connection is requested to the called terminal, the exchangers 31 and 32 communicate with the sound providing apparatus 50 based on the first and the second information to receive a specific sound from the sound providing apparatus 50 and to provide the called terminal with the received specific sound as a ringback tone replacement sound.

The specific sound may be one among a personal information sound, which corresponds to distinguishable specific information, which can identify the subscriber or can represent the subscriber's character such as the subscriber's phone number, name or nickname; a common replacement sound (hereinafter "replacement sound") such as the personal information sound, which the subscriber has chosen as a ringback tone replacement sound for a corresponding caller; and a sound which combines these replacement sounds. In addition, the specific sound is one among: a combination of the personal information sound with the basic replacement sound which cannot be classified by the called subscriber; a combination of the personal information sound with the replacement sound which can be classified by the called subscriber; and a combination of the personal information sound with the replacement sound which is set by time zone. Herein, the combination of sounds means that the personal information sounds are variously combined by being inserted before, after or between the replacement sounds, which are to be outputted one after another. That is, the personal information sound and the replacement sound are combined and sequentially arranged, such as: (personal information sound)+(general ringback tone); (personal information sound)+(replacement sound)+(personal information sound); (replacement sound)+(personal information sound)+(replacement sound); (personal information sound)+(replacement sound l)+(replacement sound 2)+ (personal information sound); (personal information sound l)+(replacement sound l)+(personal information sound 2)+(replacement sound 2); and (replacement sound l)+(personal information sound l)+(replacement sound 2)+(personal information sound 2). The sound providing apparatus 50 stores the specific sound classified by the subscriber, and communicates with the exchangers 31 and 32 via the gateway 40 to provide the exchangers 31 and 32 with the stored specific sound.

The sound storage managing server 70 communicates with the sound providing apparatus 50 via the Internet 60 to classify the kinds of the specific sound to be provided to the exchangers 31 and 32 based on identification information of the called subscriber requested for the call connection, identification information corresponding thereto and/or information of time zone when the call connection is requested, e.g., classifying the various kinds of sounds based on each condition such as who calls to, which group a caller belongs to, age, sex, occupation of a caller and/or when a subscriber is called, etc. For example, the sound storage managing server 70 assigns a code to each of various specific sounds stored in the sound providing apparatus 50. Thereafter, when a called individual subscribes to the service or changes information, the called individual chooses a specific caller, a caller group and a calling time zone, and sets a specific sound corresponding to the chosen items. Then, the sound storage managing server 70 stores information for the above items in the form of a table and so on, and controls the sound providing apparatus 50 in such a manner that the relevant sound is provided with the exchanger 32 based on the information in the table. The web server 100, which is connected to the sound providing apparatus 50 or the means for controlling sound providing 70 via the Internet 60, adds the specific sounds to the sound providing apparatus 50 and changes information of the means for controlling sound providing 70 for setting the specific sound e.g., a specific caller, a caller's group and a calling time zone, etc and codes corresponding thereto. A subscriber can perform the operation through a web page provided by the web server The operation of said apparatus for transmitting the specific sound in Fig. 1 is described in detail below. If a called individual wants to subscribe to the service of transmitting a specific sound, the called individual contacts the service provider to which the called individual belongs, and the called individual is registered in the subscriber database 80 which requests registration of the sound transmitting service to the home location register 10, which is a network element. Then, the home location register 10 sets the service in its subscriber database, and transmits a routing data to the exchanger 31 or 32 which currently provides the subscriber with the service. The exchanger 32 stores the received service information and the routing data in the relevant subscriber service data. Accordingly, if a calling subscriber requests a call setting to the relevant called subscriber, the call-terminating exchanger 32, knowing based on the registered information of the called subscriber that the specific sound transmitting service is set, call-connects to the sound providing apparatus 50 simultaneously by paging the called subscriber for the call request. At this time, the sound providing apparatus 50 cooperates with the sound storage managing server (IP Server; 70) to inquire what specific sound is set by the subscriber, and the sound storage managing server 70 provides the sound providing apparatus 50 with a code for the specific sound set by the subscriber in response to the inquiry. The sound providing apparatus 50 sends the specific sound for the relevant code instead of an existing ringback tone so that the calling subscriber can hear the sound until the called subscriber answers. If the called subscriber answers the call, the call-terminating exchanger 32 disconnects the communication between the sound providing apparatus 50 and the called subscriber and establishes the call between the called subscriber and the calling subscriber. Fig. 2 is a flow chart explaining an embodiment of the procedure of transmitting personal information of an apparatus as shown in Fig. 1. The call-terminating exchangers cooperate with the sound providing apparatus 50 to transmit a specific sound to a caller as a ringback tone. Referring to Fig. 2, if a caller requests a call to a called subscriber (or a called terminal) of the present service, the relevant call-originating exchanger 31 requests location information of the called subscriber to the home location register 10 (S501). If the request for the location information is received, the home location register 10 requests a routing to a call-terminating exchanger, and the call-terminating exchanger 32 provides the home location register 10 with the routing information, for example, TLDN (Temporary Local Directory Number) in response to the request (S502,

S503). The home location register 10 transmits the routing information to the call- originating exchanger 31, and the call-originating exchanger 31 requests an ISUP call connection to the call-terminating exchanger 32 based on the routing information to establish a communication path between the exchangers (S504, S505). Afterwards, the call-teπriinating exchanger 32 checks the service setting information of the called subscriber in order to confirm whether or not he subscribes to the service according to the present invention. If it is confirmed that he subscribes to the service, the call-terminating exchanger 32 requests an ISUP call connection to the sound providing means based on the routing information to establish a communication path. The originating and terminating phone numbers are provided with the ISUP call connection request. At this time, a communication path is established in the call- originating exchanger 31, the call-terminating exchanger 32 and the sound providing apparatus 50 (S506). The sound providing apparatus 50 requests a specific sound code to the sound storage managing server 70 based on the path of the originating and terminating phone numbers received at the above step S506, and the sound storage managing server 70 searches for the designated specific sound code linked to the received originating and terminating phone numbers in response to the request to transmit the searched specific sound code to the sound providing apparatus 50. In addition, the sound providing apparatus 50 transmits a specific sound corresponding to the transmitted specific sound code as a ringback tone to the caller via the established communication path (S507, S508, S509). As mentioned above, if the called subscriber receives a call while the specific sound is transmitted as a ringback tone, the call-terminating exchanger 32 recognizes the fact and requests an ISUP call release to the sound providing apparatus 50 so that the call can be released. At the same time, the call between the caller and the called individual is perfomed via the communication path interactively established with the call-originating exchanger 31 (S510, S511). Fig. 3 is a flow chart explaining another embodiment of the procedure of transmitting personal information in the apparatus as shown in Fig. 1 according to the present invention. The call-originating exchanger cooperates with the sound providing apparatus 50 to transmit a specific sound to a caller as a ringback tone. Referring to Fig. 3, if a caller requests a call to a called subscriber (or a called terminal) of a service subscriber, a corresponding call-originating exchanger 31 requests location information of the called subscriber to the home location register 10 (S601). If the request for the location information is received, the home location register 10 requests routing information to a call-terminating exchanger 32, and the call- terminating exchanger 32 sends the routing information, e.g., TLDN (Temporary Local Directory Number) to the home location register 10 in response to the request (S602, S603). The home location register 10 transmits the routing information to the call- originating exchanger 31, and the call-originating exchanger 31 requests an ISUP call connection to the call-terminating exchanger 32 based on the routing information to establish a communication path between the exchangers (S604, S605). Afterwards, the call-terminating exchanger 32 checks the service setting information of the called subscriber in order to confirm whether or not he subscribes to the service according to the present invention. If it is confirmed that he subscribes to the service of the present invention, the call-terminating exchanger 32 requests an ISUP call connection to the sound providing means based on the routing information to establish a communication path. The call terminating exchanger 32 provides the called and calling phone numbers along with the ISUP call connection request. Thus, the communication path is established between the call-originating exchanger 31, the call-terminating exchanger 32 and the sound providing apparatus 50 (S606).

The sound providing apparatus 50 requests a specific sound code to the sound storage managing server 70 based on the path of the originating and terminating phone numbers received at the above step S606, and the sound storage managing server 70 searches the designated specific sound code linked to the received originating and terminating phone numbers in response to the request to transmit the searched specific sound code to the sound providing apparatus 50. Then, the sound providing apparatus 50 transmits the specific sound corresponding to the transmitted specific sound code as a ringback tone to the caller via the established communication path (S607, S608, S609). As mentioned above, if the called subscriber receives a call while the specific sound is transmitted as a ringback tone, the call-originating exchanger 31 recognizes the fact and requests an ISUP call release to the sound providing apparatus 50 so that the call can be released. At the same time, the call made between the caller and the called

• individual is performed via the communication path interactively established with the call-terminating exchanger 31 (S610, S611). Fig. 4 is a flow chart explaining an embodiment of the procedure of registering a personal information sound according to a method for transmitting personal information of the present invention. Referring to Fig. 4, in order to register the personal information sound according to the present invention, a called subscriber connects to a web or WAP server 100 via a wire or wireless communication network (or the Internet) by using a personal computer (web browser) or a PDA (700). Thereafter, the called subscriber inputs information, e.g., text, to be used as a sound of the personal information in a page for inputting personal information (not shown) provided by the web or WAP server 100 (710). The personal information means the information which can identify the called subscriber or can represent the character of the called subscriber such as phone number, and/or name or nickname. Afterwards, the web or WAP server converts the inputted text information into a voice by using a text-to-speech (TTS) engine to provide the sound storage managing server 70 with the converted voice as a personal information sound (720, 730). A person skilled in the art can easily understand that the TTS engine can be placed in the web or WAP server or can be embodied as a separate server. In addition, the person skilled in the art can understand that the present invention is not limited by the TTS engine. The sound providing apparatus 50 stores the sound while classifying subscribers into either a subscriber, who sends only a sound replacing the existing ringback tone, or a subscriber, who sends a specific sound combining the personal information sound with a replacement sound. Also, the sound providing apparatus 50 can store the specific sound while classifying it by time zone (740). In addition, during the steps 700 to 720, a called subscriber, who wants to use the service for sending a specific sound, can provide his personal information to the sound providing apparatus 50 as a voice via the ARS operated by a service provider without using the web or WAP server 100. Also, the personal information sound, which is changed by the TTS engine from text information inputted via the web or WAP server 100, and the personal information sound, hich is inputted by the ARS, can be modulated by using a voice modulation device (not shown). The voice modulation device can modulate the personal information sound to various sounds such as children, aged men, man or women. Further, the voice modulation device can modulate the personal information sound to a voice of entertainers or celebrities. The sound modulated by the TTS engine can be outputted to a melody provided by the voice modulation device. As such, various sounds modulated by the voice modulation device can be provided as personal information sounds. Thus, various sounds can be provided to users by using the TTS engine and by modulating their own voices inputted via the ARS to various tones or other voices instead of monotonous machine sounds. According to the present invention as described above, a ringback tone replacement sound is provided to the caller by combining or sequentially arranging distinctive specific information, which can identify the called subscriber or can represent the character of the called subscriber, with a common replacement sound (replacement sound) chosen by the called subscriber as a ringback tone replacement sound. Therefore, the called subscriber can effectively inform his identity. In addition, the subscriber provides the caller with individual promoting service, and the corporation subscriber can have a chance to publicly promote its company. Further, since the present invention can provide more various sounds to the caller by using the voice modulation device, the service provider can satisfy the needs of the called subscribers or the callers. According to the present invention as explained above, a user can embody a method and system for producing and transmitting multimedia contents which can be directly produced and transmitted by a user via a wire and wireless communication network. Although the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
