3A to 3E are flowcharts illustrating a process of operating the wireless terminal 2 shown in FIG. 1 as a client. The wireless terminal 2 or personal information terminal 4 described above and below is considered to be described as being the same as the client.

First, as shown in FIG. 3A, the wireless terminal 2 loads the embedded environment files when the client program for customer management of the car center starts (step C1). Substantial car center customer management takes place on the server 10.

The server 10 requests the user to input an identifier and a password through the screen of the personal digital assistant 4 through the mobile communication wireless data network 8 and the mobile phone 6 in turn, and then the mobile phone 6 And the identifier input from the personal information terminal 4 through the mobile communication wireless data network 8 in sequence and whether or not the password is correct (step C2). It is assumed that communication is performed between the personal information terminal 4 and the server 10 described below via the mobile telephone 6 and the mobile communication wireless data network 8 as described above.

The server 10 loads the initial form of the first screen into the personal information terminal 4 when the identifier and password inputted from the personal information terminal 4 are correct (step C3). The initial screen lists radio buttons for selecting a region, a number pad for entering a vehicle number, and function buttons for other functions. Here, the radio buttons and the number pad are used to search the vehicle purely, and the function buttons are designed to perform special functions.

The user looks at the screen of the personal information terminal 4 and selects a desired function (step C4).

It is determined whether the function selected in step C4 is an inquiry function (step C5).

As a result of the determination in step C5, in the case of the inquiry function, the personal information terminal 4 loads the vehicle inquiry form from the server 10 (step C6). Thereafter, as shown in FIG. 3B, the user inputs a vehicle inquiry key installed in the personal information terminal 4 (step C15). The personal information terminal 4 checks whether the key input of the step C15 is a 7-digit key input (step C16). As a result of checking in step C16, if the 7-digit key input is performed, the vehicle inquiry key input is transmitted to the server 10 (step C17). The server 10 performs a vehicle inquiry corresponding to the vehicle inquiry key input, and returns the vehicle inquiry result to the personal information terminal 4 (step C18). The server 10 determines whether the customer corresponding to the inquiry result is a new customer (step C19). As a result of the determination in step C19, when the new customer is a user, the user operates the personal information terminal 4 to create a new customer form and transmit it to the server 10 (steps C20 and C25). As a result of the determination in step C19, if it is not a new customer, it is determined whether it is an existing customer (step C21). As a result of the determination of step C21, if the existing customer is a user to operate the personal information terminal 4 to create an existing customer form and transmit it to the server 10 (steps C22 and C25). As a result of the determination of step C21, if the customer is not an existing customer, the approval rejection message is transmitted to the personal information terminal 4 so that the personal information terminal 4 displays a message of authentication failure so that the user can view it. (Step C23). After performing the above steps C23 and C25, the personal information terminal 4 provides a screen for the user to select a predetermined function (step C24). In step C24, selecting to return to the beginning or selecting end of work returns to step C3 (steps C26, C27, C28, and C29). If the authentication is successful, the server 10 informs the user whether the customer is a new customer or an existing customer through the personal information terminal 4, and in the case of the existing customer, the database 16 is opened to register the registered information. Send it to). The personal information terminal 4 loads the form so that the user can view the data transmitted by the server 10. If you are a new customer, you load customer information and vehicle maintenance. If you are an existing customer, you load customer information, vehicle maintenance, and vehicle maintenance.

As a result of the determination in step C5, if it is not the inquiry function, it is determined whether it is a letter greeting function (step C7).

As a result of the determination of the step (C7), if the letter greeting function, the information terminal 4 is a letter that the entry into the greeting portion of the DM when the DM (Direct Mail) to the customer at the member car center from the server 10 Load the greeting form "(step C8). Thereafter, when the user selects the letter greeting button of the personal information terminal 4 as shown in FIG. 3c, the personal information terminal 4 transmits a signal corresponding thereto to the server 10 to connect with the server 10 (step C30). ). The server 10 returns the letter greeting inquiry result created by the user to the personal information terminal 4 (step C31). If the server 10 confirms that the letter greeting written by the user is new, the server 10 transmits the created new letter greeting to the server 10 (steps C32, C33, and C38). When the server 10 confirms that the letter greeting written by the user is existing, the server 10 transmits the existing contents to the personal information terminal 4, and the personal information terminal 4 displays the contents in an editable text window. And the user changes this content and sends it to the server 10 (steps C34, C35, C38). If the letter greeting written by the user cannot be approved, an approval rejection message is output to the personal information terminal 4 so that the user can view it (step C36). After performing the above steps C36 and C38, the personal information terminal 4 provides a screen for the user to select a predetermined function (step C37). In step C37, selecting to return to the beginning or selecting end of work returns to step C3 (steps C39, C40, C41, C42).

As a result of the determination of the step (C7), if it is not the letter greeting function, it is determined whether or not the announcement function (step C9).

As a result of the determination of the step (C9), in the case of the announcement function, the information terminal 4 is connected from the server 10 to the client having the personal information terminal 4 when there is a notice in the server 10. Load a "Notification Form" to confirm the announcement (step C10). Thereafter, when the user selects the announcement button of the personal information terminal 4 as shown in FIG. 3d, the personal information terminal 4 transmits a signal corresponding thereto to the server 10 to connect with the server 10 (step C43). ). The server 10 returns the announcement inquiry result to the personal information terminal 4 (step C44). If there is a notice, the server 10 provides a new (most recent) announcement to the personal information terminal 4 (steps C45 and C46). If there is no notice, the server 10 outputs a rejection message to the personal information terminal 4 so that the user can view it (step C47). After performing the above steps C47 and C46, the personal information terminal 4 provides a screen for the user to select a predetermined function (step C48). In step C48, selecting to return to the beginning or selecting end of work returns to step C3 (steps C49, C50, C51 and C52).

As a result of the determination of the step (C9), it is determined whether or not the contact customer function if the notification function (step C11).

As a result of the determination in step C11, in the case of the contact customer function, the information terminal 4 loads the "contact customer form confirming the DM customer to be sent by the server" from the server 10 (step C12). The subsequent process is similar to FIG. 3D described above.

As a result of the determination of step C11, if it is not the contact customer function, it is determined whether it is a temporary storage list function (step C13).

As a result of the determination in step C13, in the case of the temporary storage list function, the information terminal 4 stores the temporary information when the customer information cannot be registered immediately after inquiring the customer information from the server 10, and then registers it later. "Temporary storage form" is loaded (step C14). Thereafter, as shown in FIG. 3E, the user operates the personal information terminal 4 and outputs a list temporarily stored in the database inside the personal information terminal 4 (step C53). The user selects the desired list (step C54). The personal information terminal 4 finds the selected list (step C55). The personal information terminal 4 loads the registration form (step C56). The user creates vehicle maintenance details or customer information according to the form (step C57). In the case of a new customer, a new customer form is created and provided to the server 10 so that the server 10 stores the data in the database 16 (steps C58, C59, and C63). In the case of an existing customer, an existing customer form is created and provided to the server 10 so that the server 10 stores the data in the database 16 (steps C60, C61, and C63). After performing the above steps C60 and C63, the personal information terminal 4 provides a screen for the user to select a predetermined function (step C62). In step C62, selecting to return to the beginning or selecting end of work returns to step C3 (steps C64, C65, C66, and C67). This temporary storage function is implemented as a combo box.

4A through 4C are flowcharts illustrating the operation of the server 10 shown in FIG. 1 step by step.

First, FIG. 4A is a flowchart showing step by step how the server 10 performs a client request, and the daemon program 14 of the server 10 reads an environment file (step S1). The daemon program 14 resides in a block state in memory like a normal daemon program.

The daemon program 14 detects the client's request and wakes it up to generate a child process using the "fork () function" to process the client's request (steps S2 and S3). Note that you must prevent the child process from forking the child process again.

The server 10 inquires the input password (step S4).

If the password is not registered as a result of the inquiry in step S4, the personal information terminal 4 is notified that the password is incorrect (step S5).

If the password is registered as a result of the inquiry in step S4, the personal information terminal 4 authorizes the search for the database 16 (step S6).

It is determined by accessing the database 16 whether the vehicle of the customer corresponding to the registered password is a new vehicle (step S7).

In the case of the new vehicle in step S7, the new vehicle signal is transmitted to the client as shown in FIG. 4B and customer information is received from the client (step S15). It is determined whether the customer registers (step S16). As a result of the determination in step S16, if the client rejects the registration, a termination signal is transmitted to the client so that the user can know the termination (step S17). As a result of the determination in step S16, when the client wants to register, personal information is checked (step S18). The customer information is converted into a database format (step S19). The customer information converted to the database format is stored in the database 16 and ends (step S20).

If it is not a new vehicle in step S7, it is determined by accessing the database 16 whether it is an existing vehicle (step S8).

In the case of the existing vehicle in step S8, as shown in FIG. 4C, the server 10 carries the signal of the existing customer and the existing customer data to the client (step S21). The server 10 searches for the function selected by the client (step S22). It is determined whether the function of step S22 is customer data search (step S23). If the client's request is a customer data search in step S23, the client data is transmitted to the client, followed by a termination signal (steps S24 and S29). If it is not the customer data search in step S23, it is determined whether the request of the client is data addition (step S25). If the data is not added in the step S25, the end signal is transmitted to the client (step S29). If data is added in step S25, essential data is checked (step S26). The data is received and converted into a database format (step S27). The converted data is stored in the database 16, and the end signal is sent to the client and terminated (step S28).

If it is not the existing vehicle in step S8, it is determined whether the letter is a greeting (step S9).

In the case of the letter greeting in step S9, the letter greeting is searched in the database 16 (step S10).

The letter greeting retrieved in step S10 is transmitted to the client (step S11).

If it is not the letter greeting in step S9, it is determined whether it is a notice (step S12).

If the announcement is in the step S12, the announcement is retrieved from the database 16 (step S13).

The announcement retrieved in step S10 is transmitted to the client (step S14).

If not known in the step (S12) is terminated.

5 is a flowchart illustrating a communication model of the wireless data processing system illustrated in FIG. 1 step by step.

First, the daemon program 14 performs "Socket (), Bind (), Listen (), Accept ()" one after the other (T1, T2, T3, T4) and waits in block state until the client requests.

The server 10 wakes up when a client makes a request to a port already established and establishes a connection, and communicates with the client through a "TCP / IP module".

When the server 10 resolves the client's request, other clients can connect as well, so the "fork () function" can be used to fulfill the role of the daemon program 14, and the port 12 can be connected to one process. To avoid being occupied by a new socket descriptor, immediately after the connection is made.

The child process checks the process identifier to prevent it from becoming a parent process so that the child never spawns a child process again.

As described above, the present invention installs dedicated software on the personal information terminal 4 and the daemon program 14 resides on the server 10 so that a general personal computer user can use "Apache (APAtCHy server)" or "IIS ( It is designed to receive service as if it is received through web server such as "Internet Information Server". Therefore, the usability and the competitiveness with respect to price are increased. By connecting the mobile communication wireless data network 8 and the personal information terminal 4, it is possible to use various services wirelessly and in real time, which can only be performed by a conventional personal computer class or more. Therefore, it is possible to provide innovative services to customers who used personal information terminals offline and customers who use mobile communication wireless data networks as a means of simple communication. The portable, easy-to-use and low-cost personal information terminal 4 can be used to transmit data for customer management of the car center to the server 10 in real time. Therefore, the customer information management of the car center is much more stable and faster than when done offline.
