The user authentication program extracts and analyzes a user ID and a password from the user information transmitted from the PDA 20 (Step S202).
[0105]
If the user ID and password can be extracted from the received user information (YES in step S203), the user authentication program sends the user information including the extracted user ID and password to the authentication server 73, and The ID is requested to be collated (step S206).
[0106]
If the user ID and password cannot be extracted from the received user information (NO in step S203), the user authentication program creates a display message that prompts the user to enter the user ID and password, The data is transmitted to the PDA 20 via the connector section 500 (step S204).
[0107]
When the input information including the user ID and the password input from the touch panel type LCD display unit 31 of the PDA 20 or the PDA key / keypad 32 is received (YES in step S205), the user authentication program transmits the information via the network interface 19. The user information including the input user ID and password is transmitted to the authentication server 73 connected to the LAN 70 to request the user ID to be collated (step S206).
[0108]
The user authentication program receives the collation result from the authentication server 73, creates response data including the authentication result of the user ID according to the collation result, and transmits the response data to the PDA 20 via the connector unit 500 of the cradle unit 40. (Step S207).
[0109]
FIG. 10 is a flowchart illustrating a processing procedure of display control in IP telephone terminal 10.
[0110]
The display control program receives the display data created by the application program and the output destination information of the display data (Step S301).
At this time, the display control program acquires the application ID 81 that has made the display request, and if the output destination of the display data is the PDA 20 (YES in step S302), the display control program executes the processing of the device accommodated in the cradle unit 40. The presence or absence is determined (step S303).
[0111]
On the other hand, when the output destination of the display data is IP telephone terminal 10 (NO in step S302), the display control program outputs the display data to LCD display unit 37 (step S307).
When the output destination of the display data is the PDA 20 and the cradle unit 40 has the PDA 20 (YES in step S303), the display control program transmits the display data to the PDA 20 via the connector unit 500 of the cradle unit 40. (Step S304).
[0112]
On the other hand, when the output destination of the display data is the PDA 20 but the accommodation of the PDA 20 in the cradle unit 40 cannot be recognized (NO in step S303), the display control program stores the display data output destination management table in the flash memory 12. With reference to 80, the setting item of the IP telephone terminal display 83 corresponding to the application ID 81 is referred to.
[0113]
As a result of referring to the setting items, if display on the IP telephone terminal 10 is possible (YES in step S305), the display control program outputs display data to the LCD display unit 37 via the LCD display control unit 18 ( Step S307).
[0114]
On the other hand, when the output destination of the display data is the PDA 20, the device is not set in the cradle unit 40, and the application ID 81 does not correspond to the output to the LCD display unit 37 of the IP telephone terminal 10, error processing is performed. The display data is discarded, and an error response is returned to the application program that made the display request (step S306).
[0115]
Note that the method of determining the output destination of the display data is not limited to the configuration described in the above-described flowchart, and automatically receives the output destination set in advance based on the application ID 81 without receiving an instruction of the output destination from the application. It is also possible to adopt a configuration in which the application data is determined or the output data output destination is determined on the application side.
[0116]
Further, the display data may be transmitted to both the IP telephone terminal and the accommodation device of the cradle unit, and the display side may determine the output of the reception data.
[0117]
The display method in the IP telephone terminal 10 and the portable terminal connectable to the IP telephone terminal 10 shown in FIG. 1 has been described as an example of the embodiment according to the present invention.
[0118]
Further, the authentication function and the authentication DB of the authentication server 73 shown in FIG. 7 are configured to be included in the IP telephone terminal 10, and the IP telephone terminal 10 itself authenticates the accommodation device of the cradle 40 and the user. Is also good.
