Method for enabling an application recorded in a radiocommunication terminal to access functions of the terminal and terminal implementing said method
First Claim
Patent Images
1. A method of restricting access of an application stored in a memory of a radiocommunications terminal to a function of the radiocommunications terminal, the method comprising:
- receiving an AT command from the application stored in the memory of the radiocommunications terminal, the AT command requesting access to the function of the radiocommunications terminal;
determining an access port corresponding to the requested function, the access port being one of a plurality of access ports, wherein each of the plurality of access ports corresponds to at least one function of the radiocommunications terminal and at least one AT command sharing a common level of sensitivity required to access the at least one function of the radiocommunications terminal via the respective access port;
determining whether to grant the application access to the access port as a function of the common level of sensitivity of the AT command and a level of confidence associated with the application; and
admitting the application'"'"'s request for access to the function of the radiocommunications terminal when the application is granted access to the access port.

Abstract
A method of enabling at least one application (22) stored in a radiocommunications terminal (10) to access functions of said terminal (10), the terminal (10) being suitable for enabling data to be exchanged in both directions in application of a data standard implementing a transfer channel that conveys so-called “AT” commands, the terminal (10) including an AT command manager (15), the method being characterized in that access from the stored application (22) to the terminal (10) takes place by exchanging AT commands via the AT command manager (15).

4. A radiocommunications terminal comprising:
-
a memory configured to store an application; and a AT command manager comprising a plurality of access ports, each access port corresponding to at least one function of the radiocommunications terminal, an AT command having a common level of security required for the application to access the respective access port, the AT command manager being configured to; receive an AT command from the stored application requesting access to a particular function of the radiocommunications terminal; determine which of the plurality of access ports corresponds to the requested function of the radiocommunications terminal; determine whether to grant the application access to the access port as a function of the common level of sensitivity of the AT command and a level of confidence associated with the application; and admit the application'"'"'s request for access to the function of the radiocommunications terminal when the application is granted access to the access port. - View Dependent Claims (5, 6)

7. A radiocommunications terminal comprising:
-
means for receiving an AT command from an application stored in a memory of the radiocommunications terminal, the AT command requesting access to the function of the radiocommunications terminal; means for determining an access port corresponding to the requested function, the access port being one of a plurality of access ports, wherein each of the plurality of access ports corresponds to at least one function of the radiocommunications terminal and at least one AT command sharing a common level of sensitivity required to access the at least one function of the radiocommunications terminal via the respective access port; means for determining whether to grant the application access to the access port as a function of the common level of sensitivity of the AT command and a level of confidence associated with the application; and means for admitting the application'"'"'s request for access to the function of the radiocommunications terminal when the application is granted access to the access port.
