However, since the computer hardware environment having the configuration as described above is only a technique well known in the art, detailed description thereof will be omitted herein. However, the user can easily and easily use the Internet by hiding all screens related to the use of the dial-up network provided in the main memory 11 and provided by Windows (Windows'95 / '98) by default from the user / application. The following describes in more detail the conditions for simplified Internet automatic access.

The present invention is to provide automatic Internet access in a PC environment can be implemented using the RAS (Remote Access Service) API (Application Programming Interface) provided by Microsoft, the use method is a user program or a dynamic link library ( By adopting both methods of DLL: Dynamic Link Library, it can be flexibly applied according to the user environment.

The present invention is largely implemented as a function for initializing an Internet auto-connect program, an Internet networking connection request processing function, a networking connection termination function, and a program termination function.

In the case of automatic internet connection, parameters input to a user or an application program are defined as a user ID, a password, and an operation type (operation type, that is, a networking connection request, a networking connection termination request, and a program termination). Therefore, in the present invention, only the three parameters mentioned above are received from the user or the application, and all other tasks are processed internally, excluding the intervention of the user or the application, thereby simplifying / automating the Internet connection using dial-up networking. Let's do it.

2 is a flowchart illustrating an embodiment of a method for automatically accessing the Internet using dial-up networking according to the present invention.

The present invention hides complex dial-up networking configuration screens from the user / application, the settings for them are handled inside the application, and items such as network connection / exit are also transmitted from the user / application. Receives and handles the request to exclude user / application intervention, simplifying the use of the Internet.

As shown in FIG. 2, the method for automatically accessing the Internet using dial-up networking according to the present invention first initializes the Internet auto-connecting program (201), and sets an operation-type and related variables from a user / application. (Optional) and the like (202) for each operation type (203), Internet networking connection request processing (204), networking connection termination 205, program termination (206) functions.

In this case, the process of initializing the Internet auto-connecting program 201 may vary greatly depending on a user program and a DLL type program. That is, in the user program, when the user clicks the present invention, the initialization process 201 of the automatic connection program for the Internet is executed, and in the DLL method, the application program calls the corresponding program using the aforementioned parameters. It takes place at the time.

In addition, the process of initializing the Internet auto-connect program 201 checks whether there is any Internet auto-connect object, searches for a modem attached to the PC, and assigns a specific object name for auto-connect to the Internet. Register "RASENTRY" according to the following steps, set up the items related to dial-up networking for registered "RASENTRY", set up the modem related items, set up the information of the relevant terminal server, and register "RASENTRY" with a specific name. It is a step of checking whether or not.

Meanwhile, the internet networking access request processing process 204 may include recovering / receiving parameters according to the operation method of the present invention, loading a registered "RASENTRY", attempting to connect to a terminal server, and a terminal server. To check if the connection to the network has been properly performed, to receive and analyze any event, and to control the transmission control protocol and Internet protocol (TCP / IP) connection Extracting the IP-address assigned to the step, and if the error occurs comprises the step of terminating the predetermined connection.

On the other hand, the networking connection termination process 205 consists of checking a Point-to-Point Protocol (PPP) session, terminating the PPP session, and "FREE" the associated structure.

On the other hand, the program termination process 206 consists of terminating the entire program, and delivering to the upper processor that the program is terminated.

As described above, the present invention is provided as a user program and a DLL program.

Therefore, in the case of a user program, a dialog screen in which each module shown in FIG. 2 is represented by a button appears, and each task is performed by a user click. In the DLL program, an identifier for each module is received from a higher level application program to process each task.

Now, the process of initializing the Internet automatic connection program 201, the Internet networking connection request processing process 204, the networking connection termination request processing process 205, of the Internet automatic access method according to the present invention through Figures 3a to 3d, The program termination process 206 will be described in more detail.

Figure 3a is a detailed flowchart of the process of initializing the Internet connection program of the Internet automatic access method using dial-up networking according to the present invention.

As shown in FIG. 3A, the process of initializing the Internet auto-connecting program 201 first checks whether a log file used for monitoring the processing process exists at a predetermined location (301).

If an error occurs, the test is terminated abnormally.

If the test is successful, Open the log file to create the initial execution information (302) and analyze the execution form (303).

As a result of the analysis, when classified as a user program method, a user ID and a password are prepared to be input from the user screen (304), and an operation mode is determined (305). At this time, if the operation is a DLL, it determines the operation form (305).

As a result of the determination, it is checked whether there is an Internet auto-connect object registered under a specific name in the user PC environment (305), and if the object is found, it is recorded in a log file to record that the initialization process was successful (306). ) Returns. On the other hand, if the object is not found, before registering a new Internet auto-connect object, it is searched whether there is a modem attached to the PC (307) and analyzed whether the modem is found (308).

As a result of the analysis, if no modem is found, it terminates abnormally.

As a result of analysis, when a modem is found, an object name for a new Internet auto-connection is assigned (in this embodiment, an object name is registered in "RASENTRY") (309), and the networking-related items of the newly registered Internet auto-connect object are added. Set 310.

Thereafter, information on the terminal server to be connected to the newly registered Internet auto-connect object is registered (311), and various items for the modem to be used by the newly registered internet auto-connect object are set (312). Thereafter, it is checked whether the new Internet auto-connect object is properly registered (313).

As a result of the check, if an error occurs, the Internet automatic connection program initialization step is abnormally terminated, and if successful, it is recorded in the log file that the initialization process was successful and returns.

FIG. 3B is a detailed flowchart illustrating a process of processing a networking connection request in the automatic Internet access method using dial-up networking according to the present invention, in which a user clicks a networking connection request button or a DLL program corresponds to a networking connection request. -TYPE) is used when a parameter is received.

As shown in FIG. 3B, the network connection request processing process 204 analyzes a form to be executed first (401) and obtains a user ID and password from a structure storing parameters received from an application program when operating as a DLL. In operation 402, when the user program is operated, the user ID and password directly input by the user are imported through the dialog screen (403).

Thereafter, the Internet auto-connect object is loaded (404) registered in the Internet auto-connect program initialization process 201, and the loaded dial-up networking object, user ID and password are mapped to a "RASDIALPARAMS" structure provided by Microsoft. (405).

Next, after attempting to make a telephone call to the designated terminal server by using the "RASDIALPARAMS" structure as a parameter (406), it is determined whether the dialing was successfully performed (407).

As a result of the determination, when an error occurs, an error cause is obtained using "RasGetErrorString_API" (408), and the extracted error cause is recorded in the open log file (409) and terminated abnormally.

As a result of the determination, when the dialing is successful, the telephone connection is successfully written to the log file (410), and an arbitrary event is received from the terminal server (411). At this time, it is analyzed whether the "RASCS_conneted" event has been received (412).

As a result of analysis, when an event other than "RASCS_conneted" is received, an error cause is obtained using "RasGetErrorString_API" (413), and the error cause is written to a log file (414). Thereafter, using the "RasHangUp_API" boils the connected phone (415) and terminates abnormally.

As a result of the analysis, when the "RASCS_conneted" event is received, it is checked whether the IP address is correctly assigned to the PC using "RasGetProjectionInfo_API" (416). At this time, it is checked whether an error has occurred (417), if an error occurs, writes the cause of the error in the log file (418) and boils the already connected phone using the "RasHangUp_API" (419) and terminates abnormally. On the other hand, if successful, the assigned IP address is written to the log file (420) and the network connection request is informed that the request is successful.

As shown in FIG. 3C, the networking connection termination request processing process 205 first checks whether there is an existing PPP session connected (501).

As a result of the check, if there is no pre-connected PPP session, after freeing the used networking information structure (502), write the time and reason why the PPP session was terminated in the log file (507) and terminate the networking connection. Treat the request as a success.

As a result of the check, when there is a pre-connected PPP session, the terminal attempts to terminate the corresponding PPP session using "RasHangUp_API" (503) and checks whether the PPP session is terminated (504). In this case, if it does not receive a confirmation message about the end of the PPP session, it waits until the corresponding message is received.

Then, when receiving a confirmation message about the end of the PPP session, after setting the variable for managing the PPP session-ID to null (505), the used networking information structure is released (506). Thereafter, the log file writes the time and reason for the end of the PPP session (507) and considers the networking connection termination request process as successful.

FIG. 3D is a detailed flowchart illustrating a program termination process in the method of automatically accessing the Internet using dial-up networking according to the present invention, and shows a procedure of processing the same when the user / application completes the present invention.

As shown in FIG. 3D, the program termination process 206 first checks whether the Internet auto-connect program is operated as a DLL (601), and executes it as a hidden type (HIDDEN-TYPE) when operated as a DLL. Close (603) otherwise close the user screen that is explicitly shown (602).

Thereafter, the process transmits that the screen / process is closed to the higher process (604) and terminates the program (605).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawings.

The present invention as described above, by first hiding the setup / connection / exit screen for using dial-up networking from users, even users without any knowledge of networking through one-click (one-click) Since it can be connected to the Internet casually, improves user utilization and provides PPP communication, it can be applied as an underlying protocol of any service field based on the Internet.
