When requesting data by accessing a server of a company that is located at a physically remote location from the mobile communication device (PDA, mobile phone, etc.) (S32), whether the mobile communication device is exposed to the wireless LAN (S33) (S34). After determining whether it is necessary to make a wireless Internet call using RAS using a mobile phone module (S35), a network connection is attempted. After collecting final destination address information using the destination (destination) address (S37) (S36), and checking the network status (S38) to see if a network connection is possible with a server to request a resource, and if the connection is normal ( S39) The request information is formatted according to the mobile middleware communication protocol (S41), and the server session of the final destination address is requested (S42).

After the server session is connected, the unnecessary information of the requested data is removed, the information is compressed (S45), and the standardized data conforming to the middleware communication protocol is transmitted (S46). After the data transmission (S47) is completed, the server waits for a reaction event (S49). When there is a response event of the server (S50), when receiving the server response data (S52) examines whether the result value is normally received (S53), and passes the timeout message to the user after the limited time passes to the next action. It is possible to (S54), and pass the result value to implement the normally received data in the user interface (S56).

The process of processing the server session will be described in more detail. When the session connection request is accepted (S59), a multi-session is generated by multithreading for multi-connector processing (S60) (S61 to S63). Each session independently receives the request data (S64), classifies the characteristics of the request data (S65) and determines whether to connect to the database (S66) (S67) or to call another service connector (S68). . It connects to a database and processes it according to business logic (S69), and formalizes the processed data (S72). If the processing information is returned to the requester (S73), and the processing is normally performed (S75), the connector is cleaned up (S76), the session resources are cleaned up (S77), and the server session is terminated.

Hereinafter, a preferred embodiment of the present invention for achieving another object will be described in detail with reference to the drawings.

Referring to Figure 4 to describe in more detail the method for supporting the Korea-Japan business building to support the development productivity of the mobile business,

In order to extract a schema for processing a procedure from a database operating system containing a database or another commercial program using the same (S80 and S81), information for transmitting information with a client, which is a mobile communication device, is obtained (S82). If the user selects, the server source code for the user's favorite compiler is generated (S83). Basically, the logic part of the generated server code is corrected and supplemented (S84, S85), and the completed server code is completed into executable object code using the selected compiler (S86).

Referring to the method of generating a client source (S85) using the interface definition from the code completed using the development tool of the server in more detail,

When selecting a function called in the client application (S87), and informs the logical location information of the server (S88), by selecting the interface attribute to be used in the client application (S89) to the defined input, output information attributes ( S90) Generate the correct basic client code (S91). If you want to generate the code of the entire basic skeleton of the developer's client project can generate the code (S92). Generate a mobile middleware-related API for interfacing with the server using the defined attribute information (S93), and completes through a compilation process for generating the generated client code into an execution object suitable for the selected mobile communication device (S94). do.

Hereinafter, various interlocking technologies for solving the above technical problem will be described in detail with reference to the accompanying drawings.

First, referring to the drawings, the linkage technology with the SAP R / 3 system, which provides the functions of protecting the concurrent users and protecting the transaction in the event of data contention, using distributed object design technology and multi-thread technology for stable and scalable structure It demonstrates in detail.

5 is a diagram illustrating a connection relationship between an SAP R / 3 system, which is one of other server resources, and mobile middleware according to the present invention. 5,

The SAP R / 3 system sets the location information (destination server address) of the system operating around the solid server already implemented (S100), selects the target BAPI function or RFC function to be used by the client which is the mobile communication device (S101). After generating the DCOM source supporting the distributed object (S102), compiling and linking the DCOM code for the C ++ (S103) and the interface definition (S104), the middleware server execution code is generated (105) and registered as a mobile middleware server. (S106).

In more detail the process of generating the client code using the interface definition,

After selecting the target function, input the information related to initialization such as destination address information of the server (S107), select the information to be delivered and returned to the server (S108), input the transfer factor (S109), mobile middleware After generating the API to be used in (S110), after defining the interface to send and receive with the server is defined user interface and operation procedure using the (S111), and generates the source code to be executed in the client, the mobile communication device (S112), Compiles and links to an executable object suitable for the client, which is a mobile communication device, to generate an executable file (S113).

Next, the end application user needs to try to connect to the server resources and the Internet by making a mobile communication device dial. At this time, the user of the application program needs to perform a relatively cumbersome task of starting the application program after making a RAS, and sometimes complains of inconvenience in use due to an error of not following the procedure. To solve this problem, we will show you how to provide an API to accommodate this requirement by calling a simple function in the mobile middleware so that the application can automatically perform the task of automatically progressing to the Internet connection.

When requesting a resource that requires a server resource (S121), it is determined whether the application is in the Internet dialing state (S122), or if it is exposed to the WLAN network (S123). Recognition (S124) After determining whether it is a new connection to the state and executes Internet dialing according to the situation (S125), if the connection with the server is normally completed, using the environmental information to request the connection to the server (S123) (S127), perform data transmission and reception operations (S129), perform the normal termination operation (S131), and delete and clean up the session (S132) and ends. When the power of the mobile communication device is cut off without normally terminating the application (S128), the session cleanup management is called (S130) to release the connection state with the server.

This series of tasks not only automates the dialing state, but also removes the mistake of the user's inadvertent connection with the session, so that the user can always be on standby to keep voice communication available. have.

Next, since the system implemented by the present invention is based on the client and server architecture, which is a mobile communication device, it is assumed that a client application program, which is a mobile communication device, is always changed. Therefore, it is necessary to solve the problem of how to handle the version management of the client application program and generate a low cost with an efficient communication structure. The flow of action to solve this problem is explained.

7 is a diagram illustrating an application program version control operation flow of a mobile device. Referring to Figure 7,

When operating a program to be executed in the client, which is a mobile communication device, the client version is compared with the version managed by the server (S141), and if it is determined that the current version is a lower version (S142), requesting the higher version managed by the server ( S143), and download the upper version using the mobile middleware file transfer adapter (S144), and if the download is completed normally (S145), decompresses the downloaded compressed file in an executable state (S148) The execution of the lower version is stopped (S149), the higher version is executed (S150), and the client task execution is continued with the new version (S152). If the higher version, the client operation continues (S151) to the current version.

Although one preferred embodiment according to the present invention has been illustrated and described above, the present invention is not limited to the above-described embodiment, and the present invention is not limited to the scope of the present invention as claimed in the following claims.
