Therefore, when a user downloads a music file to the mobile terminal, when the music file is stored in the mobile terminal, there is a problem in that some music files are deleted and only another music file is downloaded.

In addition, in the case of music data downloaded to a mobile terminal, there is also a considerable amount of music data used as a substitute for ringing tones of a mobile terminal. In this case, the music data to be downloaded and stored in the mobile terminal is often not part of the whole song. In addition, a part of one song downloaded due to the limit of the storage capacity of the mobile terminal may occur. When only one part of the song is downloaded, the user wants to listen to the entire song when he / she likes listening to music through the mobile terminal, but only regrets only part of the playback. Accordingly, there is a demand for a technology for selecting a desired song through a mobile terminal, fully listening to the selected song, and allowing a plurality of songs to be continuously listened to.

On the other hand, a wireless communication network such as a general wireless data network can transmit a much larger amount of data than a mobile communication network, but the terminal receiving the data cannot process sound at all, and thus transmits and plays music files. There is a drawback that is not available.

Mobile communication systems that provide wireless communication services to mobile subscribers are developed through first generation analog AMPS (Advanced Mobile Phone Systems) and second generation cellular (PC) / Personal Communication Services (PCS). Recently, the third generation high speed data communication IMT-2000 (International Mobile Telecommunication-2000) has been developed and commercialized.

IMT-2000 is a global multimedia mobile communication service with integrated wired / wireless concept that can send and receive voice, data, and video at high speed in one wired and wireless environment. It is a new personalized third generation (3G) service that allows users to use the service with a single terminal or user access card anywhere in the world. IMT-2000 becomes global roaming by using global standardization and same frequency, and it is possible to multimedia communication such as high quality voice, internet and video.

The IMT-2000 service may be classified into a Code Division Multiple Access (CDMA) 2000 1X service and a CDMA 2000 1x Evolution Data Optimized (EV-DO) service.

CDMA 2000 1X (hereinafter referred to as '1X') service is 14.4 Kbps, which is the speed supported by the existing IS-95 A / B network using the IS-95C network evolved from the existing IS-95A and IS-95B networks. It is a service that enables wireless Internet at up to 144 Kbps, much faster than 56 Kbps. Accordingly, the mobile communication system is capable of providing various multimedia services (AOD, VOD, etc.) as well as improving existing voice and wireless application protocol (WAP) service quality through 1X service.

Meanwhile, the CDMA 2000 1x EV-DO (hereinafter referred to as 'EV-DO') service is a high data rate (HDR) technology, which is developed by Qualcomm using CDMA technology. It is a new technology of packet wireless data transmission and enables mega high speed data transmission. The transmission speed is up to 2.4 Mbps in the forward direction and 307.2 Kbps in the reverse direction. It is a service implemented in the same wireless system as the ADSL method used in the wire.

Hereinafter, for convenience of description, the CDMA 2000 1X system will be abbreviated as "1X system" and the CDMA 2000 1x EV-DO system "as" EV-DO system ".

In the current mobile communication system, the EV-DO system is used interchangeably with the existing 1X system. That is, the EV-DO system and the 1X system are installed at the same time in one wireless base station or base station controller, but operations are performed separately. In other words, the base station transmitter is provided with a channel card for the EV-DO system and a channel card for the 1X system, respectively. The base station controller also includes a data processing board for processing packet data to be transmitted and received with the EV-DO system and a data processing board for processing data to be transmitted and received with the 1X system. Therefore, when multimedia data is transmitted from a mobile communication system such as a wireless base station or a base station controller to a mobile terminal, the multimedia data is transmitted at high speed to the EV-DO system, and low speed data such as voice or data is transmitted to the 1X system.

1 is a block diagram schematically showing the configuration of a music banking service system 100 using a CDMA 2000 1x EV-DO system according to an embodiment of the present invention.

The music banking service system 100 according to the present invention includes a hybrid mobile terminal 110, a 1X transmitter 122, a 1X controller 132, and a mobile communication switching center (MSC) in a configuration for transmitting voice signals or low-speed data. And a hybrid terminal 110, an Access Network Transceiver Subsystem (ANTS) 124, and an EV-DO (EV-DO) as a configuration for transmitting multimedia data. Network (ANC) controller (ANC) 134, a packet data node (PDSN) (hereinafter referred to as PDSN) (150), and IP (Internet Protocol) network 160. Here, the IP network 160 is connected to a client computer 162 which requests to download a plurality of music or music videos in the music bank or to record them on a compact disc.

The music banking service system 100 stores a plurality of music or music videos selected and accessed by the hybrid mobile terminal 110 in the music bank of the subscriber, and requests a download from a computer or the like through the IP network 160. Music banking server 170 that downloads music or music videos, records music albums on compact discs, and delivers them, and stores music data by classifying songs by songs, artists, genres, and preferred age groups. And a music bank database 172 having a music bank storage area for subscribers of the music banking service.

The hybrid mobile terminal 110 is a mobile communication terminal that can accommodate all the communication services provided by the EV-DO system and the 1X system, respectively. The hybrid mobile terminal 110 wirelessly connects to the music banking server 170 to search for a music or music video that the user wants to listen to or watch, and temporarily downloads, outputs, or displays the found music or music video. It allows you to make selections, and commands you to save the selected music or music video to a music bank.

In addition, the hybrid mobile terminal 110 periodically monitors two systems, 1X system and EV-DO system, at regular time intervals. That is, in the operating state of the 1X system that does not use the EV-DO system, the hybrid mobile terminal 110 periodically searches for the EV-DO system in the middle of communicating with the 1X system, and performs EV in traffic using the EV-DO system. Periodically scan the 1X system in the middle of communicating with the DO system.

For example, in a traffic state with the EV-DO system, the hybrid mobile terminal 110 responds to a call signal such as a voice call connection signal or a short message that may be transmitted from the 1X system, and periodically registers its location with the 1X system. It connects to 1X system and updates system resource such as system message, access message. Therefore, the hybrid mobile terminal 110 is provided with a voice signal transmission service and a low-speed data transmission service through the 1X system, and a high-speed data service such as a music data stream or an image through the EV-DO system. In order to accommodate both systems, a hardware configuration corresponding to each of the two systems is provided, but the two components operate independently of each other. Hybrid mobile terminal 110 having such a complex function and configuration is generally set to switch to the 1X mode to communicate through the 1X system in the standby state waiting for communication, to check whether the data received by the EV-DO system For this reason, the controller switches to EV-DO mode at regular intervals and then returns to 1X mode.

The switch function between the 1X system and the EV-DO system is handled by software embedded in a mobile station modem (MSM) chip, which is a type of baseband modem embedded in the hybrid mobile terminal 110, and is managed by hardware. This is accomplished by tracking the frequencies used in both systems by means of a searcher connected to the MSM chip. That is, when the hybrid mobile terminal 110 switches from the EV-DO system to the 1X system, the servo module tracks and switches the frequency used by the 1X system under the control of the MSM chip, and switches from the 1X system to the EV-DO system. When switching, it tracks and switches the frequency used by the EV-DO system.

In the EV-DO mode, in case of a forward link for transmitting multimedia data such as music data from the EV-DO system to the hybrid mobile terminal 110 via an access network (AN), time division multiple access (TDMA) : A reverse link that transmits a large amount of messages using a time division multiple access scheme and transmits data from the hybrid mobile terminal 110 to an EV-DO system via an access network (AN). In this case, a code division multiple access (CDMA) scheme is used to accommodate a plurality of subscribers.

In addition, the hybrid mobile terminal 110 switches to the 1X mode at regular intervals to check whether there is an incoming voice signal in the 1X mode while receiving multimedia data from the EV-DO system in the EV-DO mode. Returns to the EV-DO mode again.                     

The 1X transmitter 122 and the EV-DO transmitter 124 are base station transceiver subsystems (BTSs) 120 that transmit voice signals or multimedia data to the hybrid mobile terminal 110 through an air interface. Provides a mobile communication service to transmit. For example, the 1X transmitter 122 provides voice or low speed data to the hybrid mobile terminal 110, and the EV-DO transmitter 124 mainly provides multimedia data or high speed data to the hybrid mobile terminal 110.

The 1X controller 132 and the EV-DO controller 134 serve as base station controllers (BSCs) 130 to control mobile communication services of the base station transmitter 120. That is, the 1X controller 132 connects a plurality of 1X transmitters to the mobile switching center 140 to control transmission of voice or data, and the EV-DO controller 134 connects a plurality of EV- to control transmission of multimedia data. The DO transmitter is connected to PDSN 150, which is a packet data network.

In particular, when there is a call connection request for multimedia data transmission from the hybrid mobile terminal 110, the EV-DO controller 134 fails due to the failure of the EV-DO transmitter 124 or the EV-DO controller 134. When the call connection with the terminal 110 cannot be established, the hybrid mobile terminal 110 stops the call connection to the EV-DO system by transmitting a connection deny message to the hybrid mobile terminal 110. Make a call connection to the system.

The mobile switching center 140 physically connects a plurality of 1X controllers 132 with another mobile switching center or a public switched telephone network (PSTN) 146, and a hybrid mobile terminal (PSTN). When there is a call connection request from 110, the communication connection path of the 1X system is switched and provided.

In addition, the mobile communication switching center 140 includes a home location register (HLR) 132, which is a database that stores information on mobile terminals registered with itself, and mobiles within its service area. The mobile terminal obtains the information of the mobile terminal from the visitor location register (VLR) 134, which is a database that stores information of the terminal, and processes the call of the subscriber.

EV-DO system as a packet data system for transmitting only data is coupled to the PDSN 150 based on TCP / IP, and transmits and receives various data with the IP network 160 in the form of an IP packet (Internet Protocol Packet). . Then, after receiving the packet data transmitted from the IP network 160 to the hybrid mobile terminal 110, based on this for generating a packet data service, for example, MPEG packets, etc., and generates the packet data in the TDM method It is loaded on the divided time slot and transmitted to the hybrid mobile terminal 110. In addition, the CDMA modulated data received from the hybrid mobile terminal 110 is generated to generate an IP packet based on this, and then the corresponding IP packet is transmitted to the PDSN 150.

EV-DO systems are required to maximize throughput per sector and assign each user the highest data rate possible depending on the channel situation. Accordingly, the EV-DO system provides a multimedia service with maximum power when transmitting multimedia data to one hybrid mobile terminal 110 in one sector.

In the forward link in the EV-DO system, the base station transmits the maximum power capable of transmitting multimedia data without power control and enables hard handoff. In the reverse link, power control is performed for each hybrid terminal, and softer or soft handoff is possible.

The client computer 162 is connected to the IP network 160 by wire, such as a cable, and the subscriber who is subscribed to the music banking service accesses the music banking server 170 over the Internet, and stores the music stored in his music bank. A terminal used to download files or music videos, etc., or to request recording on a compact disc.

The music banking server 170 not only provides a search function for searching music or a music video to the hybrid mobile terminal 110 subscribed to the music banking service, but also provides a music bank for storing the found music or music video. The client computer 162 connects to the Internet to provide a function for downloading music or music videos stored in a music bank or recording them to a compact disc.

In addition, the music banking server 170 is constructed in a web language such as HTML (HyperText Markup Language) or WML (Wireless Markup Language), which allows a user of the hybrid mobile terminal 110 to use a website access or call setting service. Operate web sites for wired and wireless connections. Therefore, when the subscriber connects to the music banking server 170 through the wired Internet network using the client computer 162, the MIN of the hybrid mobile terminal 110 of the subscriber must be separately input. On the other hand, when the subscriber connects to the music banking server 170 through the wireless internet network using the hybrid mobile terminal 110, the music banking server 170 accesses the request data to the user without requiring a separate MIN. Store with the MIN of the hybrid mobile terminal 110. At this time, the music banking server 170 stores the MIN and access request data of the subscriber station in the music bank database 172 in a hierarchical manner. Thus, the music banking server 170 has an internet address (www.musicbanking.co.kr) so that the client computer 162 can access the Internet.

The music banking server 170 also provides a multimedia playback module (not shown) that allows a user to listen to or display music or music videos by the client computer 162 and the hybrid mobile terminal 110.

The music bank database 172 stores website information data provided by the music banking server 170 according to an exemplary embodiment of the present invention. Accordingly, the music banking server 170 provides the website information data stored in the music bank database 172 to the subscriber's hybrid mobile terminal 110 or the subscriber's client computer 162 as a web screen. In addition, the music bank database 172 stores basic personal information of the subscriber who has subscribed to the music banking service, MIN, and information (music name, file type, data path, data size, etc.) of the music or music video selected by the subscriber. .

The music bank database 172 may be a relational database management system (RDBMS) such as Oracle, Infomix, Sybase, or DB2, Gemston, Orion, or O2, or the like. The object-oriented database management system (OODBMS) and the XML Native Database (Excelon, Tamino, Sekaiju, etc.) using an XML Native Database can be implemented for the purposes of the present invention, and It has the appropriate fields or elements to achieve its function. Since the construction and management of the database required for the present invention can be easily carried out by those skilled in the art, detailed description thereof will be omitted.

On the other hand, the data for the music or music video stored in the music bank database 172 is WML (Wireless Markup Language) based data format for output or display in the hybrid mobile terminal 110, and IP network 160 MPEG-based video data format for downloading and displaying or outputting from the client computer 162.

2 illustrates a channel structure of a forward link transmitted from the EV-DO transmitter 124 to the hybrid mobile terminal 110.

As illustrated in FIG. 2, the forward link includes a pilot channel, a medium access control (MAC) channel, a control channel, and a traffic channel. The pilot channel is a channel through which the EV-DO system transmits a pilot signal for tracking the hybrid mobile terminal 110. The hybrid mobile terminal 110 receives one or more pilot signals transmitted through the pilot channel, and receives the received pilot. The radio base station is connected to a wireless base station which has transmitted the pilot signal having the largest signal strength among the signals. In addition, the pilot channel is also used for reference when the hybrid mobile terminal 110 performs coherent detection of the radio base station of the EV-DO system.

The MAC channel is mainly used for controlling the reverse link, and is composed of a reverse activity (RA) channel and a reverse power control (RPC) channel. Here, the RA channel is used to determine the transmission speed of the reverse link, and is also used to request the hybrid mobile terminal 110 to lower the transmission speed when the channels of the reverse link become saturated. In addition, the RPC channel is a channel used by the hybrid mobile terminal 110 to control transmission power in case of signal or data transmission on the reverse link.

The control channel is a channel used to transmit a broadcast message to the hybrid mobile terminal 110 in the EV-DO system, or to transmit a direct message for directly controlling a specific hybrid terminal. Is a channel used to transmit only pure packet data to the hybrid mobile terminal 110 in the EV-DO system.

Meanwhile, referring to FIG. 3, the structure and data structure of the time slot of the forward link will be described. The forward link includes 16 time slots per frame, and one frame has a time of approximately 26.67 ms. With intervals. One timeslot consists of 2048 chips, first half slot 1024 chips and second half slot 1024 chips, with 1.67 ㎳ per time slot. With intervals.                     

Each of the first half slots and the second half slots contains data slots 400 chips, MAC slot 64 chips, pilot slot 96 chips, MAC slot 64 chips, and data slot 400 chips. It is composed of

4 illustrates a channel structure of a reverse link transmitted from the hybrid mobile terminal 110 to the EV-DO transmitter 124.

The reverse link shown in FIG. 4 uses a code division multiple access scheme as in the 1X system, and is largely composed of an access channel and a traffic channel. The access channel consists of a pilot channel and a data channel, and the traffic channel consists of a pilot channel, a MAC channel, an acknowledgment channel, and a data channel. Here, the MAC channel is composed of a Reverse Rate Indicator (RRI) channel and a Data Rate Control (DRC) channel.

The access channel is used to transmit an Origination Signal (Connection_Request Message) and a Registration Signal (Route_Update Message). The access channel has a low transmission rate of 9.6 kbps for the stability of the wireless channel.

The pilot channel is used for reference when the hybrid mobile terminal 110 performs coherent detection of the wireless base station of the EV-DO system, similar to the pilot channel in the forward link described with reference to FIG. 2. The data channel is a channel used to transmit data necessary for the hybrid mobile terminal 110 to access the EV-DO system.

The traffic channel is a channel used by the hybrid mobile terminal 110 to transmit packet data to the EV-DO system and supports various data transmission rates according to a wireless environment.

The pilot channel performs the same function as the pilot channel described in the access channel. The MAC channel is a channel used to control the data rate of the traffic channel and is a channel that is continuously formed while the hybrid mobile terminal 110 maintains a connection with the EV-DO system. In the MAC channel, the RRI channel is a channel used to inform information of the data rate of the traffic channel transmitted by the hybrid mobile terminal 110, and the value of the RRI is displayed on the hybrid mobile terminal 110.

In addition, the DRC channel determines the demodulated data rate according to the channel environment of the current forward link and informs the base station. That is, the EV-DO transmitter 124 transmits the packet data to the hybrid mobile terminal 110 using the time slot of the forward channel. The criteria for determining the transmission rate of the packet data is the DRC transmitted by the hybrid mobile terminal 110. Cover value. In order to determine the DRC Cover value, the hybrid mobile terminal 110 measures a Carrier to Interference (C / I) value received from the EV-DO transmitter 124 to determine a DCR Cover value capable of achieving the maximum transmission rate. .

The response channel is a channel used by the hybrid mobile terminal 110 to transmit a response signal for data received in a time slot unit in a forward direction. The response channel has a length of 1 times the length of a basic timeslot in order to reduce interference. Occupies only two.

The data channel is a channel used by the hybrid mobile terminal 110 to transmit only packet data, similar to the data channel of the access channel.                     

Meanwhile, a packet, which is a basic transmission unit of a traffic channel, has a length of 26.66 ms and is transmitted by changing the transmission bit rate for each packet size. The pilot channel, traffic channel, DRC channel, and response channel used in the reverse link are distinguished by using an orthogonal Walsh code.

Next, a music banking service process using the CDMA 2000 1x EV-DO system according to an embodiment of the present invention will be described based on the above-described system configuration and the flowcharts shown in FIGS. 5 and 6.

When the mobile terminal 110 is powered on by the user, the hybrid mobile terminal 110 receives a pilot signal from the 1X controller 132 and the 1X transmitter 122 of the 1X system to initialize the 1X mode (Initialization) and maintains a standby state. The standby state is maintained after initializing the EV-DO mode using a system parameter message acquired at the time of mode initialization and a pilot signal from the EV-DO controller 134 and the EV-DO transmitter 132.

The hybrid mobile terminal 110 that initializes the 1X mode and the EV-DO mode performs dual monitoring between the 1X mode and the EV-DO mode, and monitors at a period of 5.12 seconds in the 1X mode. The hybrid mobile terminal 110 updates the overhead message to perform call registration that may occur in the 1X system and location registration with the 1X system while staying in the 1X system. Here, the call request refers to a case in which a voice call connection is generated or a short message is transmitted to the hybrid mobile terminal 110 through the 1X system.                     

Overhead messages include system parameter messages, access parameter messages, extended system parameter messages, neighbor list parameter messages, and channel list parameter messages. Etc. are included.

The system parameter message includes information such as a network ID (NID), a slot cycle index (SCI), and a packet zone ID (Packet Zone_ID), which are essential for call reception. The access parameter message contains the information required for the hybrid mobile terminal 110 to access the 1X system from the EV-DO system, and the extended system parameter message is added as the evolution from the Interim Standard (IS) -95B system to the 1X system. System parameters are included.

In addition, the neighbor list parameter message includes information on a cell ID and the like for a neighboring cell adjacent to a cell where the hybrid mobile terminal 110 is located, and the channel list parameter message includes a call by the hybrid mobile terminal 110. Information is provided on a frequency channel capable of transmitting and receiving data or voice.

However, in the mobile communication environment where the EV-DO system and the 1X system coexist and are used, the hybrid mobile terminal 110 stays in the 1X system until all the overhead messages described above are updated while monitoring the 1X system. The system releases the call connection of the hybrid mobile terminal 110 when the hybrid mobile terminal 110 that is connected does not respond to the pilot channel within a predetermined time, 5.12 seconds.                     

Meanwhile, while the hybrid mobile terminal 110 monitors the 1X system and the EV-DO system in a standby state, music among a plurality of menus basically provided by the terminal itself by a key input operation by the user of the hybrid mobile terminal 110 is performed. When the banking service menu is selected and the send key is pressed, connection request data for connecting to the music banking server 170 is generated and wirelessly transmitted to the EV-DO system. Here, the connection request data includes the internet address of the music banking server 170.
