Abstract

In an mobile communication system having a transmitting and receiving unit, a control unit, and a handset in a mobile station, it is possible to fix a restriction against a use of a specific function of the mobile communication system, or it is possible to change a restriction against a use of a specific function of the mobile communication system after inputting a security code, enabling the use of only one kind of control unit in the handset.

Claims

1. An apparatus for controlling a call in a mobile communication system provided in a mobile station having a handset, the mobile station operated by a subscriber to a mobile communication service and having functions for restricting calls, said apparatus comprising:

first storing means for storing first information of functions for restricting call, where the first information cannot be rewritten, said first storing means including

restriction command storing means for storing restriction commands, each indicating restriction of a specific function of said mobile communication system; and

selection command storing means for storing a selection command identifying one of said restriction commands in said restriction command storing means;

second storing means for storing second information based upon the first information from said first storing means, where the second information can be rewritten, the second information including one of the restriction commands from said first storing means in accordance with said selection command stored in said storing means except when said selection command indicates a restrictive mode may be changed;

rewriting means for rewriting the second information stored in said second storing means in accordance with input information from the handset; and

restriction means for restricting at least one of incoming and outgoing call operations by the mobile communication system in accordance with the second information stored in said second storing means.

4. An apparatus as set forth in claim 1, wherein the second information restricting calls is derived from a code included in the first information stored in said first storing means.

2. An apparatus for controlling a call in a mobile communication system provided in a mobile station having a handset, the mobile station operated by a subscriber to a mobile communication service and having functions for restricting calls, said apparatus comprising:

first storing means for storing first information of functions for restricting calls, where the first information cannot be rewritten;

second storing means for storing second information based upon the first information from said first storing means, where the second information can be rewritten;

rewriting means for rewriting the second information stored in said second storing means in accordance with information input from the handset, said rewriting means including

means for determining whether a signal for changing a condition of a restrictive mode has been input from the handset;

means for determining whether a correct security code has been input after the signal for changing the condition of the restrictive mode has been input from the handset; and

means for determining whether a new restriction command has been input from the handset after input of said correct security code; and

means for restricting at least one of incoming and outgoing call operations by the mobile communication system in accordance with the second information stored in said second storing means.

3. An apparatus for controlling a call in a mobile communication system provided in a mobile station having a handset, the mobile station operated by a subscriber to a mobile communication service and having functions for restricting calls, said apparatus comprising:

first storing means for storing first information of functions for restricting calls, where the first information cannot be rewritten, said first storing means including

restriction command storing means for storing restriction commands, the restriction commands including a combination of at least two restrictions for indicating restriction of a specific function of said mobile communication system, and

selection command storing means for storing a selection command identifying one of said restriction commands in said restriction command storing means,

second means for storing second information based upon the first information from said first storing means where the second information can be rewritten;

rewriting means for rewriting the second information stored in said second storing means in accordance with information input from the handset;

restriction means for restricting at least one of incoming and outgoing call operations by the mobile communication system in accordance with the second information stored in said second storing means.

5. An apparatus for controlling a call in a mobile communication system provided in a mobile station having a handset, the mobile station operated by a subscriber to a mobile communication service and having functions for restricting calls, said apparatus comprising:

first storing means for storing first information of functions for restricting calls, where the first information cannot be rewritten;

second storing means for storing second information derived from a code, included in the first information stored in said first storing means, the code specifying one among a plurality of functions for restricting calls, including an outgoing call restriction, an outgoing and incoming call restriction, a manual lock, an automatic lock, and at least one combination of the restrictions and locks, where the second information can be rewritten;

rewriting means for rewriting the second information stored in said second storing means in accordance with information input from the handset; and

restriction means for restricting at least one of incoming and outgoing call operations by the mobile communication system in accordance with the second information stored in said second storing means.

6. An apparatus as set forth in claim 5, wherein the functions for restricting calls further include a memory access restriction, a long distance call restriction, and a combination of the memory access and long distance call restrictions.

7. An apparatus as set forth in claim 6, wherein the functions for restricting calls further include a total talk time count restriction.
