As shown in FIG. 1, the wireless data communication system according to the present invention has three main means, that is, cellular communication, for providing wireless data communication services to passengers in a moving vehicle and passengers waiting for a vehicle in history. In other words, it will use the means of near field wireless data communication and satellite communication.

As shown in FIG. 1, the system according to the present embodiment includes a main communication unit 100 installed in a main passenger vehicle and a sub communication unit 200 installed in a general passenger vehicle in a mobile vehicle. Includes components such as history 300 and inter-history relay network 400, core network 500, and satellite 600.

The main communication unit 100 installed in the main vehicle is provided with a vehicle server 101, a vehicle GW (gateway) 102, a vehicle base station 103, a communication antenna 104, a communication AP (access point) ( 105, and a satellite receiver 106. The vehicle server 101 manages contents and users, and serves to process service requests generated from a mobile terminal, a personal data assistant (PDA), a notebook, and the like in a general vehicle. It also stores membership information and performs functions such as authentication and billing, and also updates content. The vehicle gateway 102 is a device in which a function of identifying whether each link can be communicated to a commonly used router is added. The vehicle gateway 101, the vehicle base station 103, and the communication AP (located in the main passenger vehicle 100) are provided. 105), the satellite receiver 106 and the vehicle AP 202 located in the general passenger vehicle 200 are connected to perform switching and routing. The vehicle base station 103 performs a function of a wireless private automatic branch exchange (WPABX) and at least one mobile terminal, which are generally used in a building, a campus, and the like, and is located in a secondary communication unit 200 in a general passenger vehicle. The vehicle antenna 201 constitutes a private cellular network that communicates with the mobile terminal 203, and the communication antenna 104 located in the main communication unit 100 in the main passenger vehicle performs one or more portable terminal functions to perform a history 300. It communicates with the general antenna 304 of the history base station 303 located within or the general antenna 402 of the general base station 401 located in the inter-historic relay network 400. Traffic mainly transmitted / received through the communication antenna 104 may be management, authentication, and billing traffic requiring real time, and a small amount of real time traffic may be possible.

The communication AP 105 processes quasi-real-time Internet requests through high-speed communication with the communication AP 306 in the history when the vehicle stops in the history 300 and updates the content in an area where satellite reception is impossible. In addition, management, authentication, and charging traffic performed through the communication antenna 104 may also be transmitted through the communication AP 105 during the stop. The satellite receiver 106 serves to update content through satellites in an area where satellite reception is possible.

There may be several sub-communication units 200 installed in a general vehicle and a general vehicle, and a vehicle antenna 201 and a vehicle AP 202 are installed, and the vehicle antenna 201 is a user's portable terminal 203 and a vehicle AP. 202 communicates with the PDA 204 and the notebook 205. In this case, the vehicle antenna 201 and the vehicle AP 202 may be installed in a single general vehicle or several vehicles in accordance with the generated traffic. The vehicle antenna 201 is connected to the vehicle base station 103 of the main communication unit 100 to establish a private cellular network, and the vehicle AP 202 may be directly connected to the vehicle gateway 102 through a wired LAN. A vehicle repeater may be installed in some cases at the position of the vehicle antenna 201, and the number of subscribers increases, so that when multiple vehicle antennas 201 are needed, two or more FA (Frequency Allocation) can be used to recycle frequencies. It is good.

In the history 300, all of the equipment installed in the main carriage 100 and the general carriage 200 is installed to provide the same service as in a vehicle. The history server 301 has a similar function to the vehicle server 101. Since the history GW 302 is always connected to the wired network 503 and the central server 501 of the core network 500, real-time content can be updated. The point is different. The history GW 302 also has a similar function to the vehicle GW 102, except that the history GW 302 is always connected to the wired network 502 such as the history server 301 to process internet traffic in real time. The history base station 303 is also connected to the mobile terminal 309 through the history antenna 305 to form a private cellular network in the same way as the vehicle base station 103 but is connected to the general antenna 304 and the public cellular network 503. The difference is different. The communication AP 306 performs a high speed communication with the vehicle when the vehicle is stopped, and the satellite receiver 307 may be used to collectively update contents and the like where satellite reception is possible. The history AP 308 is connected to the PDA 310 and the notebook 311 to form a WLAN network.

The inter-history relay network 400 is not limited between history and history, and may be any region except history and vehicles. The general base station 401 and the general antenna 402 communicate with the communication antenna 104 of the main communication unit 100 in real time to transmit and receive management, authentication and billing information when the vehicle is moving, and in some cases, a communication AP 403 may be placed to communicate in real time with the communication AP 105 in the vehicle. In this case, too many communication APs 403 may be required for the network.

In the core network 500, a central server 501, a wired network 502, and a public cellular network 503 are located. The wired network 502 is a central server 501, a public cellular network 503, and communication. It is connected to the AP 403, and the public cellular network 503 is connected to the wired network 502, the general base station 401. The wired network 502 is not necessarily a public wired network.

The satellite 600 receives the information such as contents from the central server 501 and transmits them in a batch so that the vehicle server of the main communication unit 100 can be transmitted through the satellite receiver 106 and the satellite receiver 307 in the history, respectively. 101 and the contents of the history server 201 of the history 200, and user information.

2 is a configuration diagram showing an example of the configuration of the vehicle base station 103. The vehicle GW connection unit 112, the vehicle antenna connection unit 113, and the communication antenna connection unit 114 are formed around the control unit 111 in the center. The vehicle GW connection unit 112 is connected to the vehicle GW 102 in an Ethernet or ATM (Asynchronous Transfer Mode) manner, and the vehicle antenna connection unit 113 is connected to the vehicle antenna 201 in a conventional cellular network method. When the control unit 111, the vehicle GW connection unit 112, and the vehicle antenna connection unit 113 are combined, the function of the existing WPABX is performed. Meanwhile, the communication antenna connection unit 114 is connected to the communication antenna 104 serving as a mobile terminal, so that the communication channel 104 receives the pilot channel, the synchronization channel, and the paging received from the general antenna 304 or the general antenna 402. The channel and traffic channel information is received and sent to the control unit 111. The control unit processes various channel information and retransmits the vehicle antenna 201 to the mobile terminal 203 through the vehicle antenna connection unit 113. In addition, traffic such as authentication and billing is transmitted and received to and from the management server 121 of the vehicle server 101 via the vehicle GW 102 via the vehicle GW connection 112. At this time, the communication antenna 104 is a combination of several general mobile terminals, so that several FAs can be used at the same time, and the connection method between the existing mobile terminal and the PC is used to connect the communication antenna connection unit 114 and the communication antenna 104. USB (Universal Serial Bus), serial communication, etc. can be used, Ethernet or ATM can also be used.

3 is a configuration diagram showing an example of the configuration of the history base station 303. Consisting of the historical GW connection unit 322, the history antenna connection unit 323, the general antenna connection unit 324, the cellular network connection unit 325 around the center control unit 321, the history GW connection unit 322 and the history antenna connection unit The 323 serves as the vehicle GW connection unit 112 and the vehicle antenna connection unit 113 of the vehicle base station 103 to perform the functions of the existing WPABX via the control unit 321. On the other hand, unlike the vehicle base station 103, the history base station 303 has a general antenna 304, which is a wireless antenna of the general public cellular network to transmit and receive wirelessly with the communication antenna 104 of the base station 103. When the general antenna connection unit 324, the control unit 321, and the cellular network connection unit 325 are combined to form a general cellular communication base station, the historical base station simultaneously configures a public cellular network and a private cellular network. The public cellular network and the private cellular network are connected to each other through the control unit 321. For example, traffic such as authentication and billing is transmitted through the central GW connection unit 322, the control unit 321, and the general antenna connection unit 324. 501 and the vehicle server 101 will be exchanged.

4 is a diagram illustrating an example of a configuration of the vehicle server 101. The vehicle server 101 has various servers according to respective functions therein. The management server 121 is a server that manages everything related to this service, such as authentication and charging, content update and management.

The content server 122 is downloaded to a mobile terminal such as broadcasting, video on demand (VOD), music on demand (MOD), ringtones, characters, images, cartoons, e-books, news, education, and other content such as magic and multipack. It also provides a program to run.

The application server 123 is a server that informs the execution result to the mobile terminal or PDA by inputting a parameter from the portable terminal or the PDA for a program that cannot be executed due to lack of computing capability of the portable terminal or the PDA. This may be the main target.

The game server 124 is a server in charge of an online network game, for example, a go-stop game played by several people.

The communication server 125 is a server responsible for text and video chat, and can support community functions and voice calls. For example, if the ideal type is currently boarding the same subway or train according to the information of the ideal type already inputted, chat or It can also provide functions such as finding an ideal type to send a message.

The Internet server 126 is a server providing a quasi-real time Internet, and provides a portal in the form of a walled garden to provide services such as securities, living information, reservations, shopping, and banking in quasi-real time. However, at the request of the user, a more expensive real-time Internet is also available.

The location based service (LBS) server 127 extracts the location information extracted by using the GPS (Global Positioning System) of the satellite receivers 106 and 307, the base station ID of the cellular network and the received signal strength or the location of the WLAN network. As the subway and train moves based on the role of providing local information, coupon service, event information, alarm service.

The storage server 128 allows users to store their data and programs by assigning accounts to users, providing services and storage spaces such as mail and personal information management systems (PIMS), and managing schedules such as Outlook. Provides sync function with software.

Each server is connected to each other to provide a service. For example, when downloading and executing an online game, when a user connects to the management server and completes an authentication process, the management server causes the content server to provide a service. When the user can download the online game program and the user installs and connects the online game, the user is connected to the game server to provide a service, and data such as usage time is completed through the management server and the payment of the fee.

In the management server 121, authentication and billing functions can be provided by dividing the membership system and the temporary system. The member system pays a certain amount in advance and registers and uses an ID, while the temporary system is added to the billing statement of the mobile terminal in the future when a service is requested. Can be used. When using a wireless LAN using a PDA or a notebook, unlike a mobile terminal, there is no legitimate way of performing authentication on a temporary basis. Therefore, after sending the authentication letter to the mobile terminal and accessing it through the authentication character, the mobile terminal can be used in the future. You can use the billing method to bill your bill.

In addition, in the case of a broadcast service provided by the content server 122, a code division multiple access (CDMA) code is used and a time division multiple access (TDMA) share a time slot in a mobile terminal using a cell broadcasting service (CBS). This allows multiple mobile terminals to receive the same download traffic information at the same time. In the case of PDAs and laptops, it can naturally be provided using the broadcasting capability of the wireless LAN.

The history server 301 and the central server 501 also have a similar function to the vehicle server 101 but have a larger processing capacity and storage space toward the history server 301 and the central server 501.

5 illustrates an authentication, service use, and a charging method thereof according to a service use request. First, when the subscriber makes a service request (S100), the management server 121 checks the type of the user's terminal (S110), and when the terminal is a mobile terminal, a mobile terminal number (MIN: mobile identification number) and a mobile terminal electronic serial number. Perform authentication by interworking with the existing cellular network database using (ESN: electronic serial number) (S120), if the user is using a PDA or laptop (S111), if the user is a registered user receives the ID and password Perform the authentication (S121), if not the user selects the payment method (S112) by sending the authentication number to the mobile terminal to authenticate by inputting the authentication number (S122), or enter the license number to the management server 121 Authentication is performed by setting a time limit and a condition set in advance in the license number (S123).

For a user authenticated according to the above process, if the user is in history, a service profile composed of user information, service type, billing method, etc., is brought to the history server 201 and the vehicle server 101 if the user is in a vehicle. Accordingly, the user uses the wireless Internet and the content service (S140). When the user applies for service termination (S150), after updating the user profile of the central server and performing the charging, the user profile of the history server and the vehicle server is deleted (S160), and the use of the service is terminated (S170).

6 is a flowchart illustrating a processing method when a telephone is received while starting and using the service in a mobile terminal in a vehicle. First, when the user requests the service to be started using the mobile terminal 203 (S200), the mobile terminal 203 connected to the general antenna 304 or the historical antenna 402 in the existing history is a vehicle antenna. The location change registration request is requested through 201, and the vehicle base station 103 receives the request and registers the mobile terminal 203 to itself and, if possible, provides the service using a FA different from the existing FA. (S210). At this time, the paging channel information previously received by the mobile terminal 203 is received by the vehicle base station 103 through the communication antenna 104 and retransmitted through the vehicle antenna 201 (S220). When a call is received for the mobile terminal 203 that is using the service (S230), the mobile terminal 203 and the vehicle server 101 store the current service related information and then re-create the general antenna 304 or inter-historic history. Handoff is performed to the general antenna 402 (S240) to make a phone call (S250). At this time, the general antenna 304 in history and the general antenna 402 between history may vary according to the movement of the vehicle. When the telephone call is over, the mobile terminal 203 performs handoff to the vehicle antenna 201 to restore the stored service information to receive the present service (S260), and terminates the service after using the service (S270). . In FIG. 6, a case of receiving a call is taken as an example, but in fact, the present invention can be extended to other cases using a traffic channel. In addition, in the case where the mobile terminal 309 is used in the history 300, the same method may be used. In this case, the control unit 321 of the history base station 303 interworks with the public cellular network and the private cellular network, thereby performing the public cellular network. It can be done naturally by passing paging information to a private cellular network.

7 is a flowchart illustrating a history and an inter-vehicle handoff processing method. First, when a change in signal strength is detected between the mobile terminal 203, 309 and the history antenna 305, the vehicle antenna 201, the PDA 204, 310 or the notebook 205, 311 and the history AP 308 and the vehicle AP 202 ( S300), by continuously measuring the signal change (S310), if the signal continues to be greater than the vehicle toward the history because it is moving to the vehicle in the history, so that the service information of the user from the history server 301 to the vehicle server 101 It transmits and notifies the central server 501 of the user's location change (S320). In addition, by examining the service server used during the movement (S330), the management server 121, the content server 122, the application server 123, LBS server 127, the storage server 128 to provide an uninterrupted service ( S340) If the service server to be used is the game server 124, the communication server 125, and the Internet server 126, the service is interrupted and the user is notified of the service through a screen or sound, and then provides the service without interruption as much as possible (S341). . This is because the game server 124, the communication server 125, and the Internet server 126 are unable to move in real time as the vehicle moves. By this process, the handoff between the history and the vehicle is completed (S350). If moving from the vehicle to the history in contrast to the above, the vehicle server 101 transmits the user's service information from the history server 301 and informs the central server 501 of the user's location change (S321). Investigate the service server used during (S330) management server 121, the content server 122, the application server 123, the Internet server 126, LBS server 127, storage server 128 if the service without interruption If the service server to be used (S342), the game server 124, the communication server 125 to inform the user that the service can be interrupted through the screen or sound, and provides the service without interruption (S342). This is because in the case of the game server 124 and the communication server 125, real-time communication with an opponent who has communicated with each other in a vehicle becomes impossible.

8 illustrates a method of updating content of a vehicle server and receiving data from the outside of the vehicle. First, the vehicle GW 102 grasps the communication status of the area where the vehicle is currently located (S400), and when the satellite reception is possible and the satellite reception is possible (S410), receives the content and external data through the satellite network (S410). S430), when satellite reception is impossible and wireless LAN communication is possible (S411), by requesting content and external data through the wireless LAN network (S421) and receiving (S431),

If satellite reception and wireless LAN communication are not possible and high-speed cellular communication such as mobile Internet, broadband mobile communication, and IMT-2000 is possible (S412), it is possible to anticipate the required bandwidth at a lower priority than authentication, billing, and management data if possible. Request and receive content and external data through the cellular network (S422), (S432),

If only low-speed cellular communication such as 800 MHz and 1,800 MHz is possible, and satellite communication, wireless LAN network, and high-speed cellular network communication are not possible, it is necessary to estimate the required bandwidth with lower priority than authentication, charging, and management data. The content and external data are requested (S423) and received (S433).

If the content and the external data is additionally needed to check additionally (S440), the content and external data reception process is repeated again.

9 is a configuration diagram showing an example of the configuration of the vehicle GW 102. A vehicle server connection unit 132, a vehicle base station connection unit 133, a vehicle AP connection unit 134, a communication AP connection unit 135, and a satellite receiver connection unit 136 are formed around the control unit 131 in the center. The vehicle GW is basically similar to a general router, but communication antenna 104 and general antenna 304, 402, in-vehicle communication AP 105, intra-historical communication AP 306 and inter-historic communication AP 403, and satellite receiver 106 Since the connection between the satellite and the satellite 600 is not always possible, the vehicle base station connection unit 133, the communication AP connection unit 135, and the satellite receiver connection unit 136 determine whether the link is available through the control unit 131. In this case, the control unit 131 determines which link to transmit and receive data through. The control unit 131 configures a queue by prioritizing each traffic, and the real-time traffic generated during movement is transmitted and received to the communication antenna 104 through the vehicle base station 103 and the real-time traffic and non-stop traffic generated when the vehicle is stopped. Real time traffic is transmitted and received through the communication AP (105). In addition, the traffic requesting the collective update is received through the satellite receiver 106 in the section where satellite reception is possible, otherwise through the communication AP 105 at the time of stopping. In addition, traffic generated from the mobile terminal 203, the PDA 204, and the notebook 205 can limit the destination address to the vehicle server 101 and conditionally restrict the traffic not to prevent unnecessary internal traffic. It can increase security.

The history GW 302 is similar to the vehicle GW 102 except that it is always connected to the central server 501 through the wired network 502.

FIG. 10 illustrates a routing method of a vehicle gateway. When a packet is received (S500), first, the destination address of the packet is checked, and if the address is the vehicle server 101 (S510), the route is routed to the vehicle server 101 (S511). ,

If the address is not the vehicle server 101, check whether the vehicle internal address is again, and if the destination address is the vehicle internal address (S520), check whether the packet is legal or not, and route it only inside the vehicle if it is legal (S521).

When the destination address is outside the vehicle, if the packet requires a real time, a small reply packet, or a packet corresponding to management, authentication, and charging (S530), the packet is transmitted through the vehicle base station 103 and the communication antenna 104. Routing to the cellular network, if the packet requires non-real-time or requests a large number of reply packets to check whether the external WLAN network is available (S540), if available, routed to the communication AP 105 (S541), otherwise After buffering and the WLAN network becomes available, routing is performed (S542), and the routing operation is terminated (S550).

The cellular network described above is not limited to the 800 MHz mobile communication or the 1,800 MHz personal communication service (PCS: PCS), which is generally described, and is a broadband mobile communication using IMT-2000 (international mobile telecommunication-2000) and 2 GHz band. Wideband code division multiple access (WCDMA) and a portable internet (Pi) using the 2.3 GHz band.

In addition, the mobile terminals 203 and 309 are not limited to the 800 MHz mobile communication or the 1,800 MHz mobile communication, but can be extended to the terminals using the cellular communication. The mobile terminals 203 and 309, the PDAs 204 and 310, and the notebooks 205 and 311 are also applicable. In general, the mobile terminal can be divided into a mobile terminal (203, 309), a terminal using a wireless LAN network consisting of an access point, PDA (204, 310) and a notebook (205, 311) can be used simultaneously. In the case of a terminal, the mobile terminal 203, 309, the PDA 204, 310, and the notebook 205, 311 may be classified according to which network the terminal uses.

In addition, using the high-speed communication capability of the mobile Internet, communication antennas 104, general antennas 304, 402, in-vehicle communication AP 105, intra-historic communication AP 306, and inter-historic communication AP 403 may be used. It can be used or replaced.

By using the wireless Internet and content providing system in vehicles and history according to the present invention, wireless data communication terminals such as mobile phones, PDAs, and laptops can be provided to passengers in subways, billions of trains, buses, and airplanes. By using this service, it is possible to provide wireless internet and contents service including broadcasting service simply, economically and stably.

In general, wireless Internet and content services using a mobile phone have excellent demands due to its high portability, but the price is very expensive, which has hindered the expansion of the use of the present invention. Because it is built, it can be provided at a very low price.

In the case of public transportation, it is expected to spread the service very rapidly due to the long sitting time and the high service ripple effect. Especially, since it is a service for mobile phones owned by almost all citizens of the nation, the number of users is dramatically increased. If you take into account the revenue of content that is expected to be several times that of simple telecommunications, you can get a chance to position yourself as a cash cow.

In addition, uninterrupted service is possible between vehicles and history, and can be used while waiting for subways, trains, and buses, and location-based services can be used to get a lot of responses from customers during commute or travel. It can be a big advantage because it can be used for a long time because it is close, stable, and low power consumption.
