Claim 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; 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.

Claim 4

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.

Claim 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, 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.

Claim 6

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.

Claim 8

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.
