BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication service, and more particularly, to a method for changing a counterpart ringtone using a Simultaneous Voice and Data (SVD) for outputting a ringtone designated by a caller as a ringtone of a called party's terminal.

The incoming ringtone is defined as a ringtone output when alerting at the called party's mobile terminal.

There is a ringtone service among mobile communication services. The ringtone service is a service that allows a user of a mobile terminal to store and register a ringtone (sound source) desired by the mobile terminal so that the registered ringtone is output through the mobile terminal when a call is received from another person. These ringtone services are supported by both domestic mobile operators, and many people express their individuality by setting the ringtones popping up.

A process of a general ringtone service will be briefly described with reference to FIG. 1. 1 is a simplified flowchart illustrating a general ring service providing method.

For the ringtone service, the user of the called terminal 1 connects to the sound source providing server 2 providing the sound source of the ringtone, and then requests one of the ringtone sound sources provided by the sound source providing server 2 (S10). Thus, the called terminal 1 is downloaded to the ringtone sound source provided by the sound source providing server 2 (S11), and stored according to the request of the called party (S12). The stored ringtone sound source is only the stored sound source information until the ringtone setting of the called party becomes a ringtone according to the ringtone setting of the called party (S13).

  Accordingly, when the called terminal 1 receives a call incoming request by the paging channel from the called mobile switching center (MSC) in response to a request of the calling terminal 3 (S14), the ringing sound source set in response thereto is reproduced. And output (S15), if the caller requests the call to the ringtone and the caller and the caller through the traffic (traffic) Z channel (S16).

As described above, the ringtone by the current ringtone service is determined by the called party and used as a means for expressing the individuality of the called party.

But communication is not only me but also a medium of communication with the caller. Therefore, communication service users have a desire to show their intentions or personalities to others in various forms, and communication service providers are trying to provide various types of services for such communication service users.

In this regard, it is a requirement of the times to make the ringtone used for the ringtone service available as an expression of the caller's personality or a means of communication rather than a choice of the called party.

However, in existing IS-95A and CDMA200 1x systems, due to technical implementation problems, the ringer of the called party cannot be changed at the caller's decision. Because, as shown in the description with reference to Figure 1, the output of the ringtone should be made as soon as the incoming call is required, there is a problem in how to bring the sound source data from the external server, not the receiver's mobile terminal to the receiver's mobile terminal There was. In other words, in the existing network, the sound source data can be obtained by using an idle channel, but there is a problem in that the ring tone of the called party cannot be changed by the caller because the capacity of the idle channel is limited.

The present invention is to solve the conventional problems, it is an object of the caller selected by the caller to be output as the ringtone of the called party.

In order to achieve the above object, if there is a call incoming request, the technical problem that the caller should be able to retrieve the selected source data from a remote external server must be solved. In order to solve the above technical problem, the present invention utilizes the SVD (service supporting voice and data) function, which is a CDMA2000 1x Rel.A function.

The SVD function can form a data channel simultaneously with forming a voice channel. Therefore, according to the present invention, when the incoming mobile terminal receives a call connection request, it sets up a voice call path for voice communication with the caller, and at the same time, sets a data call path with an external server to download the ringtone sound source data and output it as a ringtone. do.

In the present invention for achieving the above object, in the ringtone change service method of the called party using the SVD (Simultaneous Voice and Data) to output the sound source managed by the sound source providing server connected to the mobile communication network and the Internet network as the ringtone of the called party, A first step of registering, by the service subscriber, a ringing tone source for a specific target person, the sound source providing server registering first routing information for routing the ringing tone tone source to the sound source providing means; A second step of, when the caller requests a call connection, the calling exchange verifies whether the caller is a service subscriber through the calling home location register; A third step of, if the service subscriber, the originating exchange provides the destination home location register with the service identifier and requests routing information from the destination exchange to receive the response; A fourth step of receiving a call connection request from the originating exchange, establishing a voice channel with the called terminal and simultaneously requesting the called home location register for first routing information to a sound source providing means for providing a ringing tone source; ; A fifth step of the destination home location register accessing the sound source providing server to request, receive, and provide the first routing information to the originating exchange; A sixth step in which the originating exchange generates an alerting message including the first routing information and provides it to the called terminal; A seventh step in which the called terminal accesses a corresponding sound source providing means according to the first routing information and downloads an incoming ringtone sound source registered by the subscriber; And an eighth step of playing, by the called terminal, the downloaded ringtone sound source and outputting the ringtone sound as a ringtone.

In the second step, when the destination home location register receives the service identifier information, the receiver determines the specification of the destination terminal to determine whether the SVD service is available, and requests routing information from the destination exchange when the SVD service is available. It is preferable.

In the first step, when the sound source providing server is the sound source providing means, a ringtone sound source for a specific target person performs a registration function and a download function by a service subscriber in the sound source providing server. Preferably, the sound source providing means requests the registration by providing the mobile phone number of the subscriber and the service subject and the first routing information to the sound source providing server.

Further, in the first step, if the routing information corresponding to the same subscriber and service subject identification information is registered when the first routing information is registered at the request of the sound source providing means, the first step is changed to the currently received first routing information. If the registered routing information and the first routing information are different from each other, it is preferable to access the sound source providing means corresponding to the previously registered routing information and to instruct the setting of the ring tone source registered in the service to be released.

The alerting message is an AWI (Alert With Information) message, and includes the first routing information, a mobile telephone number of a caller terminal, and a mobile telephone number of a called terminal, and service identifier information is recorded in a DISPLAY-TAG field. Do.

In the fourth step, service identifier information may be included in a call connection request message transmitted from the originating exchange to the destination exchange.

The receiving terminal applied to the present invention, when receiving the alerting message outputs a ring tone which is preset or set to a default value by the called party, and when the ringtone source downloaded from the sound source providing server is downloaded, the ring tone being outputted. It is preferable to stop and play the downloaded ringtone sound source.

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

In addition, the BSCs 21 and 22 are connected to the exchanges 31 and 32 through a dedicated line, and are connected to the gateways 51 and 52 for wireless data service through a dedicated line.

The gateways 51 and 52 are located between the PDSNs 61 and 62 and the BSCs 21 and 22 to provide an interface function for providing a wireless Internet service.

The MSCs 31 and 32 are connected to the core network and are coupled to the switched telephone network (PSTN). Optionally, MSCs 31 and 32 can be coupled to PDSNs 18 and 18 '. In addition, the MSCs 31 and 32 have jurisdiction over the HLRs 41 and 42 that store subscriber information such as the location of a mobile terminal and whether to subscribe to a service through a No. 7 network based on a signaling transfer protocol (STP). Visitor location registers (VLRs) (not shown) for managing mobile terminals in the area are connected.

In addition, the MSC (31, 32) to achieve the object of the present invention, when receiving the request of the present invention from the originating exchange when performing the role of the destination exchange, providing the sound source to provide the registered sound source for the called party to the destination HLR The server 71 requests and receives corresponding URL information, and generates an AWI message including the received URL information and transmits the same to the called terminal. The AWI message will be described below with reference to FIG. 6.

The HLRs 41 and 42 manage the user's current location information and the user's profile information. In the service profile information of the user, whether or not to register the called party's ringtone change service (hereinafter, referred to as the 'called ringtone change service') of the present invention is recorded. And the HLR (41, 42) is registered URL information of the sound source providing server 71 for the present invention, when the specific URL request from the MSC (31, 32) connected to the sound source providing server 71 and the corresponding URL information And inform the MSCs 31 and 32.

PDSNs 61 and 62 are provided for providing wireless Internet service. The PDSNs 61 and 62 and the mobile terminals 1 and 3 perform IP packet communication using a point-to-point (PPP) protocol.

The sound source providing server 71 has a function of providing a sound source, a function of creating a sound source (creating a function), a function of managing a ring tone sound for each service subscriber, and / or a function of reproducing a sound source, and a sound source used for each function. It is stored and managed in the sound source DB (72).

Explaining each function, the function of providing a sound source is a function for the service subscriber of the present invention, after having the function of managing the ringtone sound for each service subscriber as a preprocessing process, the service target is connected to the identification code of the incoming ringtone sound source If requested, the sound source data is downloaded to the service person. The service subscriber is the caller and the service recipient is the called party.

The function of creating a sound source receives a new sound source from a service subscriber, or makes a character input by the service subscriber into a sound source, and gives an identification code to the sound source thus made and stores it in the sound source DB 72 together with the identification information of the service target. By the function of making this sound source, the service subscriber can make his / her own voice as the ringtone sound source of the called party.

The function to manage ringtones by service subscriber is to newly register the selected source as a ringtone sound source, create a new swap page to download newly registered ringtone sound, and change or delete the registered ringtone sound source. To be able. At this time, when a new ringtone sound source is newly registered or changed, the sound source selected (or received) by the service subscriber is matched with the identification information (mobile phone number) of the service subscriber terminal and the identification information (mobile phone number) of the service target terminal. Store and manage the identification code of the sound source DB (72).

The function of reproducing the sound source is a function used when providing a call connection sound service, which is not related to the present invention. In brief, the function of reproducing the sound source data is outputted.

Here, the conventional method for setting the voice and data channel by the SVD function will be described. Since the voice and data channel setting by the SVD function is already known, it will be briefly described.

When an AWI message is received while a voice channel is allocated according to the call, the called terminal establishes a wireless data channel with the base station.

At this time, the data channel is established between the base station and the called terminal by two methods.

The first method is described as follows. A Fundamental Channel (FCH), which is a voice call channel, is established between the called terminal and the base station. The basic channel includes a signaling channel as well as a traffic channel. Therefore, the called terminal requests the establishment of a supplemental channel (SCH), which is a data burst channel, using the signaling channel of the base channel. Accordingly, a base channel for voice service and an auxiliary channel for data service are established between the called terminal and the base station.

The second method is as follows. As in the first method, a basic channel, which is a voice call channel, is set between the called terminal and the base station. In this state, the called terminal requests the establishment of an auxiliary channel (SCH) for data transmission to the base station using a dedicated control channel (DCCH). Accordingly, a base channel for voice service and an auxiliary channel (SCH) for data service are established between the called terminal and the base station.

As described above, the wireless data channel is established between the called terminal and the base station, and at the same time, the base station controller requests the PDSN to establish a circuit and, accordingly, establishes a circuit to complete the data channel formation.

Hereinafter, a method of changing a called party ring tone using SVD according to an embodiment of the present invention will be described with reference to FIG. 5. 5 is an overall data flow diagram of a method for changing a called party's ring tone using SVD according to the present invention.

The receiving MSC 31, which receives the call connection request from the called party change service subscriber, that is, the caller 1, provides the calling HLR 41 to the calling HLR 41 and requests confirmation of the subscriber's service subscription information (S502). .

The calling HLR 41 checks the caller profile to see if the calling party related service is registered, and accordingly, confirms the ring changing service registration (S502), and notifies the calling MSC 31 of the ring changing service subscription (S503). ).

The calling exchange 31, which has confirmed that the caller 1 has subscribed to the ringtone change service, provides the caller HLR 42 with information informing the subscription of the ringtone change service and the mobile phone number of the called party 3, while the current state of the called terminal 3 is present. Request location information (S504).

When the destination HLR 42 receives the information indicating that the ringtone change service is subscribed, the destination terminal 3 checks the specifications of the destination terminal 3 to determine whether the SVD service is available (S505). When the incoming HLR 42 determines that the SVD service is not available according to the confirmation of the specification information of the called terminal 3, it notifies the calling exchange 31 of the ring change service unavailable and stops the service. Request routing information to 32) (S508).

The incoming HLR 42 grasps URL information matched to these mobile phone numbers based on the calling terminal 1 received from the calling HLR 41 and the mobile phone numbers of the called terminal, and sends them to the called MSC 32. to provide.

The destination MSC 32 provides routing information (ie, Temporary Local Directory Number (TLDN)) to the destination HLR 42 in response to the routing information request (S509), and the destination HLR 42 sends the TLDN to the source MSC 31. In step S510).

The originating MSC 31 requests a trunk call connection (or ISUP call connection) to the destination MSC 32 based on the TLDN (routing information) to form a mutual trunk call path (S511). At this time, the ISUP call connection request message includes an identifier indicating the provision of the ringing service of the present invention.

Accordingly, the called MSC 32 causes the voice channel of the called terminal 3 to be allocated through the BSC 22 and the base station 12 according to the call connection request of the calling MSC 31 (S512). The URL request message is transmitted to the destination HLR 42 for the bell change service (S513). The URL request message includes a mobile phone number of the calling terminal 1 and a mobile phone number of the called terminal 3.

The incoming HLR 42 connects to the sound source providing server 71 according to the registered URL set according to the URL request message and provides the mobile telephone numbers of the calling terminal 1 and the called terminal 3 to provide the corresponding ringing tone source. Request URL information of a specific swap page that can be downloaded (S514), and receive the corresponding URL information in response to the request (S515). When the destination HLR 42 receives the corresponding URL information, the destination HLR 42 provides it to the destination exchange 32 as response information (S516).

The destination exchange 42 receiving the URL information generates an AWI message informing the called terminal 3 of the incoming call and transmits it to the called terminal 3 (S517). At this time, the AWI message includes URL information received from the destination HLR.

When the receiving terminal 3 receives the AWI message, first, the ringing tone source preset by the called party is retrieved from the stored memory and played back and output (S518), while the ringtone set by the called party is output. The message is read to determine that it is a message for changing the called party's ringtone related to alerting according to the message identification information included in the AWI message (S519).

If it is determined that the called party's ringtone AWI message is changed, the called terminal 3 executes the alerting application program, thereby grasping the URL recorded in the corresponding field of the AWI message (S520), and performs the SVD function to determine the URL. Automatically connects to the sound source providing server 71 and requests a sound source (S521).

When the sound source providing server 71 receives the sound source request including the caller identification information and the identification information of the called terminal from the called terminal 3 connected through the PDSN 62, the sound source providing server 71 receives the call request information from the memory area of the subscriber corresponding to the caller identification information. The sound source identification code matched with the called terminal is identified, and sound source data corresponding to the sound source identification code is loaded from the sound source DB 72 and downloaded to the called terminal 3 (S522).

Then, the receiving terminal 3 stores the downloaded sound source data, stops the playback of the ringtone sound source set by the receiver currently being output, and plays the downloaded sound source to output the ringtone (S523). At this time, it is preferable that the called terminal 3 starts playing the ringtone sound source after completion of the sound source download without playing the ringtone sound source while downloading the sound source.

As a result, as described above, the called party can hear the ring tone set by the caller as the ring tone. At this time, the ringtone may be a voice of the caller "I love you", and may be a song or a sound containing the caller's favorite or a specific intention.

Hereinafter, the AWI message will be described with reference to FIG. 6. 6 is a view showing an AWI (Alert With Information) message form informing the called party's ringtone change service according to an embodiment of the present invention.

As shown in FIG. 6, the currently standardized AWI message includes a header (a) section, a signal section (alert information section, b), a called party number section (c), a calling partyy number section (d), It includes an extended display section (e).

The AWI message is a service for displaying the caller's name on the called party's mobile terminal during alerting (CNAP), or a service for displaying the caller's specified sentence or phrase on the called party's mobile terminal during alerting (lettering). (lettering service).

In the case of CNAP or lettering service, the identifier of the service is indicated in the DISPLAY_TAG field of the extended display section of the AWI message, and the content is recorded in the CHARi field.

Similarly, the AWI message according to an embodiment of the present invention may display a ringtone change service identifier in the DISPLAY_TAG field of the extended display interval e, and record URL information and caller identification information in the CHARi field.

On the other hand, in the description of the embodiment of the present invention has been described a case that the ringtone service is performed while the intention of the called party is ignored. However, considering the position of respecting the privacy of the user, the ringing service must be made to reflect the intention of the called party.

In this case, when the service subscriber selects (or registers) a recipient, the present invention solves a user privacy problem by adding a process of inquiring a recipient (a service target) to register as a service target using an SMS message. Could be.

On the other hand, in the above-described embodiment of the present invention has been described that one sound source providing server provides a sound source download service for each subscriber.

However, the ringtone service of the present invention may provide a service in connection with a separate sound source provider such as a current call ring tone ("coloring" service name of Esquite Telecom) service in actual service. In this case, the sound source providing server is used with a plurality of sound source providing servers managed by a separate sound source provider together with a sound source providing server managed by a mobile communication provider (ie, the sound source providing server of the above-described embodiment).

When a plurality of sound source providing servers are used, the subscriber registers a sound source for changing the ringing tone to different sound source providing servers, and thus URL information to easily identify URL information to be accessed by the called terminal in the mobile communication network. A registration method is required.

The URL information registration method can be easily conceived by a person skilled in the art in various ways, here will be described the most preferred example.

First, in a network configuration, there are a sound source providing server 71 managed by a mobile communication service provider and a plurality of sound source providing servers 71a and 71b managed by a separate sound source providing service provider connected to the sound source providing server 71. . The sound source providing server 71 has a function of managing a URL of a swap page to which a ringtone ringtone for each subscriber registered in each sound source providing server 71a or 71b is downloaded and providing it to the called party HLR. Hereinafter, the sound source providing server 71 managed by the mobile communication provider is referred to as the main sound source providing server 71, and the sound source providing servers 71a and 71b managed by the sound source providing service provider are the first and second sound source providing servers 71a. , 71b).

Referring to Figure 3 will be described the process of the subscriber newly register or add the ringtone ringtone source. 3 is a data flow diagram illustrating a process of adding a called party's ringtone sound source according to an exemplary embodiment of the present invention.

The subscriber accesses the first sound source providing server 71a through a mobile communication network or an internet network, and then requests new registration or addition of the ringing tone sound source (S301). At this time, the subscriber requests the addition of a ringtone by providing the mobile phone number of the subscriber mobile terminal (calling terminal), the mobile phone number of the called terminal 3, and a sound source identification code to the first sound source providing server 71a.

When the first sound source providing server 71a receives the ringtone addition request message, sets and registers the subscriber identification information, the called party's mobile phone number, and the sound source identification code as the ringtone change service sound source (S302), and the main sound source providing server 71. Request to add a ringtone by sending a ringtone change message to (S303). Here, the ringtone change message includes the subscriber's mobile phone number, the mobile phone number of the called terminal, and URL information of a swap page that enables the corresponding sound source of the first sound source providing server 71a to be downloaded.

When the main sound source providing server 71 receives the ringtone change message, the main sound source providing server 71 registers the URL information by matching the caller identification information and the identification information of the subscriber mobile terminal (304).

Hereinafter, a method of changing the ring tone sound source according to an embodiment of the present invention will be described with reference to FIG. 4. 4 is a data flowchart illustrating a process of changing a called party's ringtone sound source according to an exemplary embodiment of the present invention.

The subscriber accesses the third sound source providing server 71a managed by the sound source provider and makes a ringing request for change (S401). At this time, the mobile phone number of the subscriber mobile terminal (calling terminal), the mobile phone number of the called terminal 3, and a sound source identification code are provided to the first sound source providing server 71a to request a change in the ring tone.

The first sound source providing server 71a changes the pre-registered sound source identification code to the newly provided sound source identification code in the subscriber memory area in response to the ring tone change request (S402). At this time, the first sound source providing server 71a determines that the sound source identification code corresponding to the called terminal is stored in another sound source providing server if the sound source identification code corresponding to the mobile terminal number of the called terminal is not present in the subscriber memory area. URL information of the swap page to be downloaded to the server 71 and sound source change information (subscriber and subject identification information) are provided to request a sound source change (S403).

When the main sound source providing server 71 receives the sound source change request, the main sound source providing server 71 matches and stores the received URL information with the identification information of the called terminal and the subscriber mobile terminal, and then the sound source identification code corresponding to the identification information of the target party and the subscriber mobile terminal is stored. The stored sound source providing server is found, and the second sound source providing server 71b thus found is requested to delete the sound source identification code together with the subscriber identification information and the identification information of the called terminal (S405).

Then, the second sound source providing server 71b releases the setting of the sound source identification code matched with the subscriber identification information and the identification information of the called terminal according to the sound source identification code deletion request (S406).

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.

According to the present invention, a ringing sound source designated by a caller for an called party is downloaded from a remote server through a data channel and output as a ringtone when the alerting terminal is called, and the caller arbitrarily changes the ringtone of the called party to various callers. It is possible to create an event and to easily inform the called party of the sender's personality or intention.
