Abstract
Abstract A keypad is operated by the user to generate keypad data indicative of a destination telephone number. A storage area stores data related to the calling plan and containing data indicative of call restrictions that may apply to the destination telephone number. A call restriction storage area is used to store user-selectable call restriction data. A processor accepts and uses keypad data to access the data storage area. The processor compares data indicative of call restrictions that may apply to the destination telephone number with the user-selectable call restriction data to determine if any user-selectable call restrictions apply to the destination telephone number. The processor sets an enable signal to an enabled state if no call restrictions apply to the destination telephone number and sets the enable signal to a disabled state if call restrictions do apply to the destination telephone number.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
159 words
A system for controlling communications between a wireless communication device and a central controller having a calling plan, the system comprising: a transmitter for transmitting data from said wireless communication device to said central controller; an enable signal having enabled and disabled states for selectively enabling transmission of a call origination message from said wireless communication device to said central controller; a keypad operable by a user for generating keypad data; a storage area for storing a state table indicative of a present state of the wireless communication device, said present state being altered in response to each entry of keypad data, said state table further for storing data indicative of call restrictions applicable to said present state; a call restriction storage area for storing call restriction data; and a processor for comparing said data indicative of call restrictions applicable to said present state to said restriction data and for generating said enable signal in response to said comparison.
Claim 2
Independent Claim
159 words
A system for controlling communications between a wireless communication device and a central controller having a calling plan, the system comprising: a transmitter for transmitting data from said wireless communication device to said central controller; an enable signal having enabled and disabled states for selectively enabling transmission of a call origination message from said wireless communication device to said central controller; a keypad operable by a user for generating keypad data; a storage area for storing a state table indicative of a present state of the wireless communication device, said present state being altered in response to each entry of keypad data, said state table further for storing data indicative of call restrictions applicable to said present state; a call restriction storage area for storing call restriction data; and a processor for comparing said data indicative of call restrictions applicable to said present state to said restriction data and for generating said enable signal in response to said comparison.
Claim 3
Dependent Claim
46 words
The system of claim 1 wherein said processor sets said enable signal to said disabled state if call restrictions apply to said present state and wherein said processor sets said enable signal to said enabled state if call restrictions do not apply to said present state.
Claim 4
Dependent Claim
51 words
The system of claim 1, further including a password storage area for storing a user password, said processor further for comparing said keypad data to said user password and permitting access to said call restriction storage area to store said call restriction data if said keypad data matches said user password.
Claim 5
Dependent Claim
52 words
The system of claim 2, further including an override number storage area for storing data indicative of a override telephone number, said processor further for setting said enable signal to said enabled state regardless of whether call restrictions apply to said present state if said keypad data matches said override telephone number.
Claim 6
Dependent Claim
52 words
The system of claim 2, further including a restricted number storage area for storing data indicative of a restricted telephone number, said processor further for setting said enable signal to said disabled state regardless of whether call restrictions apply to said present state if said keypad data matches said restricted telephone number.
Claim 7
Dependent Claim
13 words
The system of claim 1 wherein said enable signal is a logical flag.
Claim 8
Independent Claim
100 words
A method for controlling communications between a wireless communication device and a central controller having a calling plan, the method comprising the steps of: generating keypad data in response to keypad entries; storing a state table indicative of a present state of said wireless communication device, said present state being altered in response to each entry of keypad data; storing data indicative of call restrictions applicable to said present state; storing call restriction data; comparing said data indicative of call restrictions applicable to said present state to said restriction data; and generating said enable signal in response to said comparison.
Claim 9
Independent Claim
100 words
A method for controlling communications between a wireless communication device and a central controller having a calling plan, the method comprising the steps of: generating keypad data in response to keypad entries; storing a state table indicative of a present state of said wireless communication device, said present state being altered in response to each entry of keypad data; storing data indicative of call restrictions applicable to said present state; storing call restriction data; comparing said data indicative of call restrictions applicable to said present state to said restriction data; and generating said enable signal in response to said comparison.
Claim 10
Dependent Claim
45 words
The method of claim 7 further comprising the steps of: setting said enable signal to a disabled state if call restrictions apply to said present state; and setting said enable signal to an enabled state if call restrictions do not apply to said present state.
Claim 11
Dependent Claim
39 words
The method of claim 7, further comprising the steps of: storing a user password; comparing said keypad data to said user password; and permitting access to said call restriction storage area if said keypad data matches said user password.
Claim 12
Dependent Claim
46 words
The method of claim 8, further comprising the steps of: storing data indicative of a override telephone number; and setting said enable signal to said enabled state regardless of whether call restrictions apply to said present state if said keypad data matches said override telephone number.
Claim 13
Dependent Claim
46 words
The method of claim 8, further comprising the steps of: storing data indicative of a restricted telephone number; and setting said enable signal to said disabled state regardless of whether call restrictions apply to said present state if said keypad data matches said restricted telephone number.
Claim 14
Dependent Claim
13 words
The method of claim 7 wherein said enable signal is a logical flag.
