How to provide real-time karaoke service in mobile communication network {Method for providing real-time karaoke service in mobile communication network}

The present invention relates to a method for providing a real-time karaoke service in a mobile communication network, and more particularly, subscribers who are in a voice call by using a simultaneous voice and data service (SVD) in a call state to provide a karaoke service. The present invention relates to a method of receiving and a recording medium recording the same.

With the development of mobile communication, multimedia services as well as voice are now provided using mobile terminals. In addition, various additional services are provided using a mobile communication network so that subscribers can be differentiated from each other. The additional service is a karaoke service. Karaoke service using a conventional mobile communication network is provided as follows. First, the mobile terminal is connected to the karaoke server. Then select the desired song through the menu provided on the karaoke server. The selected song is downloaded to the mobile terminal. The downloaded song is played by the mobile terminal. Karaoke service using the mobile terminal as described above is presented in Korea Patent Publication No. 2002-20456.

However, such a conventional karaoke service is simply a song selected by the download to the mobile terminal, there is a problem that the user can not feel the fun like a real karaoke service only because it is played on the mobile terminal.

On the other hand, with the development of Internet technology, karaoke services are provided through the Internet. It connects to a karaoke server using a personal computer and provides a karaoke service using a technology used in a voice meeting or a video conference.

Prior art related thereto is Korean Patent Laid-Open Publication No. 2000-30634. The karaoke system of No. 2000-30634 is connected to the Internet to download desired songs or play songs with a sound card during real time performance, display lyrics and background on the monitor, and input user voice data through karaoke on the Internet. Provide personal karaoke, specific karaoke, and confrontation karaoke services through a personal computer for transmission to the site, and when a user receives a song request after entering a room, find the corresponding song in a database and transmit it in real time. It includes a karaoke server that receives the user's voice data from a personal computer and evaluates the score by comparing the reference data of the song and displays the score.

In addition, Korean Laid-Open Patent Publication No. 2002-62116 discloses a karaoke service providing system and its operation method.

In this regard, when a service request is received from a customer, the server displays details of various music files previously stored in the information storage unit on the customer's terminal. If there is a selection for a particular music file of the displayed details, the server drives the play unit to play the music file. The sound signal output according to the reproduction of the music file is transmitted to the terminal of the customer. The server acquires the voice data of the customer input from the customer terminal during the reproduction of the music file through the customer terminal, and mutually converts the acquired voice data and reference tone data of the corresponding music file stored in the information storage unit. Compare and analyze error phrases with inconsistent pitch, beat, and lyrics. The server transmits at least one information of the analyzed error measure or correction advice data on a correct correction method for the error measure to the terminal of the corresponding customer.

In 2002-62116, a karaoke service using a mobile terminal is also presented. This is as follows. When a plurality of customers conduct a multi-party call using each personal terminal, when a specific customer of each customer receives a request for a multi-party song service, a call of another customer terminal connected to the call requesting customer is performed for the corresponding song service. Connect to the site. When the number of participants reaches the preset minimum number of participants, if there is a request for progress of the corresponding service, the details of various music files stored in the information storage unit are displayed on the terminal of each customer. If there is a selection for the details of a particular music file among the displayed details, the music file is controlled to be simultaneously played through the terminal of each customer who accesses the space.

However, although the karaoke service providing system described in 2002-62116 has been described to be simultaneously played in a music file in each mobile terminal participating in a multi-party call, there is no specific method for this. That is, when a music file is downloaded by connecting to a server using a mobile terminal, the download completion time may be different for each mobile terminal, and in this case, the playback timing of each mobile terminal is shifted. This may result in that the accompaniment and the song do not match at all in the mobile terminal of the counterpart even if the song is matched to the accompaniment played in the own terminal.

Accordingly, the present invention provides a real-time karaoke service by matching the playback timing at each mobile terminal when the karaoke service is provided by accessing the karaoke service using the simultaneous voice data service (SVD) while at least two or more subscribers are busy. To provide a method and a recording medium recording the same.

The present invention uses Simultaneous Voice and Data (SVD) for simultaneous service. That is, in the 3rd generation mobile communication network, a plurality of channels including a pilot channel, a synchronization channel, a paging channel, a broadcast channel, an allocation channel, a common power control channel, a common control channel, a dedicated control channel, a basic channel, an auxiliary channel, and an auxiliary code channel are included.

Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 shows a network configuration to which the present invention is applied.

The mobile terminal (MS) 11, 11 'may preferably be a cellular phone or a personal digital assistant (PDA) phone capable of wireless communication with a base station. The mobile terminal is equipped with a wireless packet data protocol as described, for example, in the EIA / TIA / IS-707 standard, and can also perform voice and data communication simultaneously with the base station (BS) 12, 12 ', and multimedia The data must be playable. The mobile station preferably performs IP packet communication using Point-to-Point Protocol (PPP).

The base station (BS) 12, 12 'is installed in a fixed position, and can provide voice and data communication services simultaneously with the mobile terminals 11, 11' wirelessly. The base station (BS) 12, 12 'is connected to the base station controller (BSC) 13, 13' via a dedicated line.

The base station controllers 13 and 13 'control the plurality of base stations 12 and 12', and are responsible for handoff processing and the like of the mobile terminal. The base station controllers 13 and 13 'are also connected to mobile switching centers (MSCs) 14 and 14' via dedicated lines, and likewise to gateways 17 and 17 'for wireless data services.

The gateway 17 is located between the packet data serving node PDSN and the base station controller BSC to provide an interface function for providing a wireless Internet service.

MSCs 14, 14 'are coupled to a public switched telephone network (PSTN). Optionally, a mobile switching center (MSC) can be connected to a packet data serving node (PDSN). In the MSC, a home location register (HLR) 15, 15 'which stores subscriber information such as the location of a mobile terminal and whether or not it subscribes to a service, and a visitor location register (VLR) for managing mobile terminals existing in a jurisdiction. 16, 16 'are connected.

A packet data serving node 18 is provided to provide a wireless Internet service. The packet data serving node (PDSN) and the mobile station (MS) perform IP packet communication using a point-to-point (PPP) protocol, and the packet data serving node performs mobile IP management and registration functions.

Karaoke server 19 includes a database storing various types of music files. The music file includes accompaniment data and lyrics data. The karaoke server 19 has a function of providing a menu screen necessary for providing a karaoke service to a mobile terminal, simultaneously transmitting a selected music file to subscribers entering the same room, and a song reservation function. And a function for managing IPs of subscribers entered and a function for controlling playback timing in each mobile terminal. The operation of the karaoke server 19 will be described later.

2 is a flowchart illustrating a karaoke server connection process in a call state according to the present invention.

First, the calling party and the calling party are in a call state when the calling subscriber enters the telephone number of the called subscriber using the mobile terminal MS and presses the SEND key (201). In the present invention, there may be two callers, but a plurality of callers may respond to the conference call. Description of the multi-party call service (conference call service) has already been carried out in the communication network, and the detailed description thereof is omitted in the present invention.

In such a call, callers may discuss entering karaoke. In the case of the conclusion of the consultation, it is determined that singing in karaoke, each caller may require the establishment of a data channel. This is done by pressing a specific Hot Key while in a call state.

The data channel is established according to a normal procedure by the request for setting the data channel (203). That is, the base station controller BSC controls the base station BS to establish a wireless data channel between the mobile terminal and the base station, and at the same time, establish a circuit between the base station controller and the packet data serving node PDSN.

In the base station BS and the mobile terminal period, data channels are established by the following two methods.

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

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

Through the above process, a line for data service is established between the mobile station and the base station controller, and a packet line is established between the base station controller and the packet data serving node PDSN. When the channel setting is completed as described above, a point-to-point protocol (PPP) connection is started between the mobile terminal and the packet data serving node, and a mobile IP for packet communication is registered (204).

When the mobile IP is registered in this way, the mobile terminal can access the karaoke server through the IP network (205). A processing procedure between the mobile terminal and the karaoke server will be described later with reference to FIG. 3. After the karaoke server is connected, if disconnection is requested (206), the established channel is released (207).

On the other hand, as a method for the mobile terminal to connect to the packet data serving node faster, the SVD service subscriber may be in a dormant state after completing the resource allocation for the PPP connection in advance. That is, the mobile exchange receives the SVD subscription information of the mobile terminal from the home location register while registering the location of the mobile terminals entering its jurisdiction, and allocates resources for data transmission to the SVD subscribers in advance. Stay dormant for the resource. In this case, the management session increases according to the number of SVD subscribers, and a waste of resources may occur, but there is an advantage that the setup time for the PPP connection is faster.

3 is a flowchart illustrating a processing procedure in a karaoke server according to the present invention.

First, in the initial state (301), if a session connection is made from the mobile terminals (302), menus for karaoke service are provided to the respective mobile terminals (303). The menu also includes room information currently available. In the karaoke server, the waterproofing is determined according to its capacity, and the number of subscribers who can enter each room is also limited. Each caller can talk to each other through the established voice channel even while connected to the karaoke server. Therefore, after accessing the karaoke server, each caller can check the room information currently available and discuss which room to enter. As a result of the discussion, the same callers enter the same room (304). The karaoke server manages IPs of subscribers entering the same room.

When subscribers enter the same room, the karaoke server provides a list of songs to each subscriber's mobile terminal. Here, it is preferable that the karaoke server provides a menu list before providing the song list to each mobile terminal. Preferably, the menu is provided with a menu for selecting a song, that is, a search menu. For example, the list may include a menu list such as latest song, genre, and search. This allows each subscriber to choose a song. At this point, each subscriber is in a call, so he can discuss who will sing what.

When the selection is made through this process (305), the karaoke server transmits the selected music file to the mobile terminal of all subscribers entering the same room (306). The music file includes accompaniment data and lyrics data. Of course, the karaoke server stores accompaniment data and lyrics data separately in a database, and transmits accompaniment data and lyrics data to a mobile terminal of a subscriber who selects a particular song, and transmits only accompaniment data to other subscribers' mobile terminals. Could be Each mobile terminal performs buffering of the music file transmitted from the karaoke server. Preferably, the mobile terminal is equipped with a program for playing music files. The playback program may play back the stored video to provide a realistic karaoke atmosphere. Each mobile terminal notifies the karaoke server of the result when the buffering of the music file downloaded from the karaoke server is completed. The karaoke server checks whether a response indicating that buffering is completed is received from all mobile terminals entering the same room (307). As a result of the check, when a response indicating that the mobile terminal is normally completed is received, a reproduction command is transmitted to all mobile terminals entering the same room (308). Accordingly, each mobile terminal simultaneously plays a buffered music file. Singing voices sung by accompaniment music by specific subscribers are delivered to other subscribers through voice call channels. Accordingly, all subscribers who enter the same room can hear the singing voice matching the accompaniment data.

Meanwhile, the karaoke server provides a reservation function. The reservation is possible when first selecting a song or while a song is playing. Subscribers can reserve several songs to sing. The karaoke server sequentially manages the reserved songs, and simultaneously transmits the reserved songs to each of the mobile terminals when data transmission is possible (309 and 310). The time point at which data transmission is possible is when the data channel is not used. On the other hand, preferably, the karaoke server does not transmit all the reserved songs to the mobile terminal even when several songs are reserved, but only one reserved music file while playing the already transmitted one music file. send. To this end, the karaoke server manages the play time information of each music file.

In more detail about the reservation, subscribers entering the same room listen to the voice of a specific subscriber, and operate the mobile terminal to switch to the menu screen of the karaoke server. Even in this state, the song sung by a particular subscriber can be heard. However, the screen displayed on the display unit is not a video but a menu screen provided by a karaoke server. Through a menu screen provided from the karaoke server, a specific subscriber selects a song for the next song and makes a reservation. When the reservation is made, the karaoke server checks whether there is a music file already reserved and transmitted to the mobile terminals entering the same room. This is to ensure that too many songs are transmitted to the mobile terminal so that the buffer resources of the mobile terminal are not wasted. If one song is currently being played on the mobile terminal and no music file is currently reserved and transmitted, the karaoke server transmits the reserved music file to the mobile terminal (310). In the present invention, a plurality of songs can be reserved, but not all of the files of the reserved songs are transmitted to the mobile terminal, but are sequentially transmitted according to the playing situation.

The karaoke server transmits the reserved music file to the mobile terminals, and waits for a response from the mobile terminal. When a response indicating that the mobile station is normally received from all mobile terminals is received (311), the karaoke server checks whether the playing time of the music file currently being played is over (312). Since the karaoke server manages the play time information of each music file, it can be achieved by operating the counter and confirming the state of the counter while transmitting a play command to each mobile terminal. As a result of the check, when the playback of the music file currently being played is completed, a playback command is transmitted to each mobile terminal notifying that the playback of the music file already buffered starts. At the same time, the karaoke server checks the playing time of the music file to be played and operates the counter.

During the provision of the karaoke service, when subscribers entering a specific room release the connection (313), the room information is initialized (314) and becomes an initial state.

Meanwhile, in the above description of FIG. 2, the data channel is set while the phone is already in a call. However, this may be modified as follows. That is, while a specific subscriber is connected to a karaoke server through a data channel, a specific subscriber may be called and invited to come to the karaoke server several times.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

According to the present invention as described above, by providing a karaoke service to subscribers in a call state by using a mobile terminal capable of simultaneous voice and data services, each subscriber is away from the space, but services such as singing in the same karaoke Can be provided.
