ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a telephone set such as a portable telephone set or the like having security functions for preventing a third party from unauthorized use thereof, a communication system with the security functions provided in a side of a network, and to a method of setting the security functions therein.
BACKGROUND OF THE INVENTION
Provided in this type of telephone set is, generally, a security function (described as a locking function hereinafter) with which the telephone set is disabled to be used unless a correct identification number is inputted thereinto to prevent any person other than an authorized owner of the telephone set from using it without authorization. Namely, the locking function is unlocked in response to input of the correct identification number thereinto.
As a conventional technology relating to this type of locking function, there is Japanese Patent Laid-Open Publication No. SHO 61-236226. In this Publication, there is disclosed a technology that calls are transmitted from a mobile telephone set or received thereby by inputting an identification number thereto at the time of using the mobile telephone set and obtaining identification by collating it to the identification number previously stored therein.
There has been proposed a telephone set in which a security function is provided so that a particular number such as a telephone number for a long-distance call or the like (described as a call-restricting function hereinafter) is restricted. In this case, the call-restricting function is also unlocked in response to input of a correct identification number thereinto.
In the conventional type of telephone set as disclosed in the publication, unlocking of a locking function and a call-restricting function is first set according to input of an identification number and call setting is carried out, which makes the operations complicated.
After the call is unlocked, and when prevention of unauthorized use of a telephone set or a restriction of particular numbers are also required for the next use thereof, the locking function and the call-restricting function are necessary to be set again, which makes the setting of a security function therein troublesome.
SUMMARY OF THE INVENTION
It is an object of the present invention to obtain a telephone set and a communication system each in which setting operations for a call following security functions can be simplified, and also to obtain a method of setting security functions in a telephone set.
It is another object of the present invention to obtain a telephone set and a communication system in which setting operations for security functions can be simplified and also to obtain a method of setting security functions in a telephone set.
With a telephone set according to the present invention, when setting a call, a user inputs call-setting information including a telephone number and an identification number; the identification number is determined from the call-setting information and is collated to the previously registered identification number; and specified call restriction is unlocked only when the inputted identification number and the previously registered one are identical, so that an input operation when setting a call is to be executed only once, which makes it possible to simplify the operation for call setting.
With a telephone set according to the present invention, a telephone number and an identification number inputted all at once are discriminated from each other by checking a discrimination code, so that, when inputting call-setting information, it is possible to continuously input a telephone number and an identification number by inputting a discrimination code.
With a telephone set according to the present invention, when an identification number is not determined, the user is asked to input the identification number again, so that, even if input miss for an identification number occurs or an identification number is not inputted, the user can complete input of correct information before call setting is executed, and with this feature, the necessity for retry of call setting can be eliminated.
With a telephone set according to the present invention, even if call restriction is once unlocked for execution of call setting, the call restrictions are automatically set again, so that it is possible to prevent a user from forgetting execution of an operation for call restriction and also trouble for setting the call restriction again is saved, and with this feature it is possible to simplify an operation for setting the security function while maintaining the security function.
With a communication system according to the present invention, when setting a call, a user inputs call-setting information including a telephone number and an identification number in the side of a telephone set; the call-setting information is transmitted to a base station; the base station receives the call-setting information, determines an identification number from the call-setting information to collate it to the previously registered identification number, and unlocks call restriction and executes call setting when the inputted identification number and the previously registered identification number are identical, so that an operation for inputting when setting a call is to be executed only once in the side of a telephone set, and with this feature the call setting operation following security functions on the system can be simplified.
With a communication system according to the present invention, a telephone number and an identification number inputted all at once in the side of a telephone set are discriminated by checking a discrimination code in the side of a base station, so that, when inputting call-setting information in the side of a telephone set, it becomes possible to continuously input an telephone number and an identification number on the condition that also a discrimination code is inputted, so that collation of an identification number and call setting can be executed in batch in the side of the base station.
With a communication system according to the present invention, when an identification number inputted in the side of a telephone set can not be identified, a base station requests a user to input the identification number again, so that, even if an user makes a mistake in or forgets inputting an identification number, the user can complete a correct operation for inputting call-setting information, and with this feature, the necessity for executing an operation for call setting again on the system is eliminated.
With a communication system according to the present invention, even if call restriction is unlocked for execution of call setting, the call restriction is automatically set, so that a work load for a user to set call setting in a telephone set is eliminated and also trouble for setting the call restriction again in the side of a telephone set is saved, and with this feature the operation for setting security functions on the system can be simplified while maintaining the security functions.
With a method of setting security functions for a telephone set according to the present invention, call-setting information including a telephone number and an identification number is inputted when setting a call; the identification number is determined from the call-setting information and collected to a previously registered identification number; and call restriction is unlocked and call setting is executed only when the inputted identification number and the previously registered one are identical, so that an operation for inputting when setting a call is to be executed only once, and with this feature the call setting operation following the security functions can be simplified.
With a method of setting security functions for a telephone set according to the present invention, a telephone number and an identification number inputted all at once are discriminated from each other by checking a discrimination code, so that a telephone number and an ident
