The present invention relates to a personal area network (PAN), and more particularly, to a PAN application service method in which a PAN terminal and an application terminal connected thereto in a personal area communication network can receive various services. The present invention relates to a PAN management apparatus for managing service transmission and reception through an application terminal.

A personal area communication network (hereinafter referred to as a PAN) refers to a personalized local area network, through which various devices located in a local area of a local area can communicate with each other. That is, the PAN terminal and its application terminals are mainly Bluetooth, infrared (IrDA), wireless LAN (WLAN), ultra wide band (UWB), mainly called a PAN terminal, also called a PAN handset. It is a local area network that is connected by using various wireless communication methods such as communication.

As an example of a PAN system, a person traveling with a notebook computer, a PDA, and a portable printer can construct a PAN system using various wireless communication methods described above to interconnect these devices. As such, when the PAN is used, various Ubiquitous services are possible by connecting to a server connected to another network through communication between the PAN terminal and various application terminals.

1 is a schematic diagram of a personal area network (PAN) system.

The PAN terminal 110 wirelessly connects with the application terminals 120 to 140. Examples of the application terminals may be the small receiver 120, the voice terminal 130 or the watch 140. For example, there is a device 130 in the form of a voice terminal connected to the PAN terminal 110 so that when a call comes in accordance with the phone function of the PAN terminal, the PAN terminal 110, which is the main body, is placed in a bag or other place. The device 130 in the form of a terminal may make a phone call such as a call or a call, and may also receive and recognize a short message. In another application example, when the PAN terminal 110 and the voice terminal 130 fall more than a certain distance, a warning sound may be generated to prevent the loss of the PAN terminal 110. Application terminals in the form of a small receiver 110 or a watch 140 may also be connected to and communicate with the PAN terminal 110 in the same manner. These application terminals 120 to 140 may also access other application servers 160 on the Internet via the PAN integrated management server 150.

However, it is not only difficult for the PAN terminal 110 to have all the application software for various types of application terminals, and even if the PAN terminal 110 has application software for existing services, it may not be known what kind of service will appear later. Therefore, when an application terminal providing a new service appears, there is a problem that the PAN terminal 110 needs to be upgraded each time so as to have application software capable of providing the service again.

Accordingly, a technical problem to be achieved by the present invention is a method for establishing a connection by providing a variety of application terminals in a PAN system, providing and receiving an application service according to the present invention, and a PAN management apparatus for managing service transmission and reception through the application terminal. To provide.

The technical problem according to the invention, (a) establishing a physical connection between the PAN application terminal and the PAN terminal; (b) receiving an IP address and accessing the PAN application terminal with the IP address; (c) querying and receiving the PAN application terminal with parameters necessary to perform a service of the PAN application terminal; (d) accessing a server storing the application program by referring to the received parameter if the application program necessary to perform the service is not installed in the PAN terminal; And (e) downloading, installing, and executing the application program from the server.

In the step (a), it is preferable to establish a connection according to a wireless connection method including Bluetooth, WLAN, IrDA, and UWB.

In addition, the step (c) is a parameter required to perform the service of the PAN application terminal, the name of the application for the service of the PAN application terminal, the service ID and location information of the server that stores the application program and delivers the query. It is preferable that it is a receiving step.

On the other hand, according to another field of the present invention, the technical problem is to determine if the service connection request from the PAN application terminal or another PAN terminal is a device that provides the service to the PAN application terminal or the PAN terminal, A control unit for determining whether a PAN application terminal or an application program that can be serviced through the PAN terminal is already installed and controlling the installation, removal, and execution of the application program according to the result; A download performing unit which downloads the application program if the application program is not installed as a result of the determination of the controller; And a PAN interface management unit for performing an interface between the control unit and the PAN software.

The control unit, the installation unit for installing the downloaded application program; According to a user's command, the removal unit for removing the application is already installed; And an execution unit for executing the application program.

The PAN service management device is an interface for inputting and displaying whether or not to download, install and uninstall the application, and download or install and uninstall the application or the error from the user through an input / output device. It is preferable to further include a user interface for performing a function.

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

2 is a reference diagram illustrating that a PAN server / routing function module is mounted in a personal area communication (PAN) terminal.

The PAN interface 210 performs a connection function with the operating system of the PAN terminal. The PAN interface 210 performs a connection with a PAN application terminal through various interfaces such as Bluetooth, WLAN, IrDA, and UWB. The PAN server / router function performing unit 220 performs a gateway and routing function for receiving a connection request from a PAN application terminal and delivering the connection request to another network.

3 is a configuration diagram of a stack of software mounted on a personal area communication (PAN) terminal.

The operating system (OS) 310 of the PAN terminal may be any of an operating system (OS) such as REX OS used in Qualcomm's MSM chipset, Windows CE of a smartphone, or Linux, pSOS, VxWorks, and the like. The PAN software 320 is mounted on the operating system 310. The PAN software 320 is installed in the PAN terminal to perform a gateway function and a server function for processing an external network connection request from an application terminal. The PAN manager 330 controls the PAN terminal so that the PAN terminal may be connected to the PAN software 320 to execute various application programs 340 and 350.

The PAN manager 330 is implemented in the form of software running under the operating system 310 of the PAN terminal to connect and control the PAN software 320 and the PAN application programs 340 and 350 in the middle. In other words, the PAN management unit 330 recognizes and searches various PAN application terminals that can be connected to the PAN terminal, the environment setting of the PAN terminal and the connection setting with the PAN application terminals, download of application programs, Performs functions such as installation, execution and deletion When implemented in the form of software, the PAN management unit 330 operates independently of the underlying physical communication interfaces (Bluetooth, IrDA, WLAN, UWB, etc.) and serves as an intelligent agent that is in charge of the interface between the applications and the PAN software. It becomes middleware.

4 is a detailed configuration diagram of the PAN manager 330.

The PAN manager includes a user interface 410, a download performer 420, a controller 430, and a PAN interface 440. The controller 430 includes an installation unit 432, a removal unit 434, and an execution unit 436.

The user interface unit 410 outputs, downloads, installs, and removes the related program for service through the application terminal, whether to perform the download, installation and removal results or errors, such as input and output devices, etc. It performs an interface function to receive and provide input from the user. In addition, the execution result of the application is transmitted through the display device.

When the service connection request from the application terminal or another PAN terminal is received, the control unit 430 determines which services the application terminals provide, and an application program that can serve through the application terminal is already present. It is determined whether it is installed and the result is shown through the user interface unit 410. If the corresponding application program is already installed in the PAN terminal, the user executes the application program through the user interface unit 410 to issue a command to receive a service, and the execution unit 436 executes the application program. As a result, a service is performed between the application terminal and the PAN terminal, and the application terminal can access a server of another network via the PAN terminal.

If it is determined that an application program capable of providing a service for an application terminal requesting access is not installed in the PAN terminal, the control unit 430 determines whether to download the application program from the user interface unit 410. When asked through, if you want to download the download through the download unit 420, the application is downloaded from the server. After downloading the application, the installation unit 432 installs the application. The removal unit 434 deletes the corresponding application program installed in order to secure the memory of the PAN terminal when it is no longer desired to receive the PAN service through the application terminal.

The PAN interface unit 440 is responsible for the interface between the PAN management unit and the PAN software. The PAN software is interfaced via, for example, a Modem Porting Layer (MPL), and interfaces with operating systems that vary by manufacturer are connected through OEM interfaces. Accordingly, when the operating system or the PAN software is changed, only the PAN interface unit 440 may be modified to maintain all the functions of the PAN management unit.

On the other hand, as well as services through the connection between the application terminal and the PAN terminal, it is also possible to service between the PAN terminals. For example, service such as exchange of business card information through data exchange between PAN terminals is possible. In this case, the PAN terminal may be provided with the service by providing the above-described PAN management unit.

5 is a flowchart of a process in which a PAN application terminal accesses a PAN terminal, and the PAN terminal downloads and executes an application program for a service of the application terminal from a server.

First, a physical connection is established between the application terminal and the PAN terminal according to various wireless connection methods such as Bluetooth, WLAN, and IrDA (S505). The PAN terminal executes the PAN management unit and allocates an arbitrary IP address to the PAN management unit (S510). Then, the PAN management unit attempts to connect to the application terminal through the IP address (S515). If there is no error, the IP connection is completed (S520). The reason for using the IP address is to perform the data communication interface through the IP socket function. When the connection between the PAN management unit and the application terminal is established through the IP address, the PAN management unit displays the AppName, the service ID, and location information of the server that stores the application. Ask the application terminal (S525). The location information may be a URL. The application terminal delivers the name AppName, service ID, and URL information of the application required by the PAN management unit (S530).

In this way, the PAN manager notifies the user of a message that a new application terminal has been found through the user interface or the like, and confirms whether or not to execute the application if it exists. If the application does not exist, it is checked whether or not to download and install it (S535). When the application exists and the user confirms that it will run, the application runs. If the application does not exist and wants to download and install it, the PAN manager disconnects from the application terminal performed through the assigned IP address (S540) and attempts to connect to the server from which the application can be downloaded ( S545). Since the location of the server has received the URL information in step S530, access to this URL. If the connection is established, the application is downloaded and installed (S550), and then executed (S555). Then, the connection between the application and the application terminal is established, and communication is performed through the application (S560).

6 is a flowchart of a process in which a PAN terminal accesses another PAN terminal or a PAN application terminal and downloads and executes the application program from a server.

The execution process is similar to the service method described above with reference to FIG. 5, except that the PAN management unit first requests initial connection establishment and finds an application terminal or a PAN terminal accordingly and establishes a connection. That is, the PAN management unit searches for an application terminal Ehss PAN terminal to connect with itself (S605). Accordingly, the connection between the PAN terminal and the application terminal or another PAN terminal is made (S505). Thereafter, steps S510 to S560 are the same as described above with reference to FIG. 5.

On the other hand, the above-described PAN service method can be created by a computer program. Codes and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the program is stored in a computer readable media, and read and executed by a computer to implement a PAN service method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

As described above, according to the present invention, when various application terminals are automatically recognized and a corresponding application program is not provided in the PAN terminal, various application services are downloaded by installing and executing the application program from a server. PAN application terminals can be easily connected to provide various additional services.
