Abstract

A function control information transmitter transmits function control information for controlling the function of a terminal device such as a mobile telephone. When the terminal device receives the function control information from the function control information transmitter, the terminal device analyzes the received function control information so as to control the function of the control object even without preparing in advance a correspondence table for controlling the function. Thus, it is possible to easily use the optimal function, application software, and a service in accordance the environment and the situation.

Claims

1. A terminal device comprising:

a reception section configured to receive function control information that an external function control information transmitting device of the terminal device transmits, said function control information including an instruction for controlling a function of said terminal device;

a monitoring section that monitors a state of the function that could be specified in said function control information;

a determination section configured to, based upon a monitoring result by said monitoring section, determine whether or not the function specified in said function control information received by said reception section is controllable, and determining whether a control of the function indicated by said function control information is executable; and

a function control section configured to, based upon a determination by said determination section, execute the control of the function specified in said function control information; and

wherein the monitoring section stores a control source, being a cause of having changed a state of the function into a current state; and

the determination section compares a first priority degree indicative of an execution of a process of a current control source of the function specified in the function control information, said current control source being stored by said monitoring section, with a second priority degree indicative of an execution of a process that is included in said function control information, thereby to determine whether or not the function control by said function control information is executable.

2. The terminal device according to claim 1, further comprising a credibility determination section configured to determine whether or not the function control information transmitting device, being a transmission source that has transmitted the function control information, and a transmission source described in said function control information coincide with each other, and determining existence of tampering of said function control information.

3. The terminal device according to claim 1, further comprising a condition determination section configured to determine whether or not a state of the terminal device meets a condition under which the function control described in the function control information is executed.

4. The terminal device according to claim 3, wherein the condition determination section decides whether or not a permission for executing the function control is requested of a user of the terminal device based upon evaluation information described in the function control information.

5. The terminal device according to claim 3, wherein, in a case where the reception section has received plural kinds of the function control information, the condition determination section is further configured to decide an order in which a function control process is executed based upon evaluation information described in said function control information.

6. The terminal device according to claim 5, further comprising:

a storage section configured to pre-store an execution order of the controllable function; and

that in a case where the reception section has received plural kinds of the function control information, the condition determination section is further configured to decide an order in which a function control process is executed based upon the execution order of the function that said storage section stores, and the evaluation information described in said function control information.

7. The terminal device according to claim 1, further comprising:

a storage section configured to pre-store an execution order of the controllable function; and

that in a case where the reception section has received plural kinds of the function control information, the determination section is further configured to decide an order in which a function control process is executed based upon the execution order of the function that said storage means stores.
