Abstract

A WLL subscriber unit (1) includes a telephone (2) that is bidirectionally coupled to a wireless transceiver (11) through a teleadapter (10). The WLL subscriber unit further includes a user interface and a data processor coupled to a memory and to the user interface for prompting a user to enter information into the WLL subscriber unit, for receiving the entered information, and for storing the entered information in the memory. The data processor is responsive to the stored information for controlling the operation of the WLL subscriber unit to accept or reject at least one of specified incoming calls or outgoing calls. In one embodiment the user interface includes a keypad of the telephone, in another embodiment the user interface includes a speech recognition function, in a further embodiment the user interface includes a speech synthesis function, and in one further embodiment the user interface includes a data port for connecting the WLL subscriber unit to an external data processor. The memory is a non-volatile memory that stores a plurality of different lists, including an incoming call rejection list, an outgoing call rejection list, and an outgoing group call rejection list. The WLL subscriber station is responsive to a telephone number dialed by a user or received from the wireless network for comparing all or a portion of the number to at least one of the stored lists, and for rejecting a call that matches a stored telephone number or portion of a telephone number.

Claims

1. A method for controlling an operation of a wireless local loop subscriber unit, comprising the steps of:

prompting a user to enter information into the wireless local loop subscriber unit;

in response to the prompt, entering information into the wireless local loop subscriber unit;

storing the entered information in the wireless local loop subscriber unit; and

controlling the operation of the wireless local loop subscriber unit to accept or reject at least one of specified incoming calls or outogoing calls in accordance with the stored information, wherein the step of storing stores the inputted information in one of a plurality of different lists, comprising an incoming call rejection list, an outgoing call rejection list, and an outgoing group call rejection list.

2. A wireless local loop subscriber unit as in claim 1, wherein said memory is a non-volatile memory that stores a plurality of different lists, comprising an incoming call rejection list, an outgoing call rejection list, and an outgoing group call rejection list.

3. A method as in claim 1, wherein the step of entering includes a step of entering a telephone number for specifying an incoming caller'"'"'s telephone number that is to be rejected.

4. A method as in claim 1, wherein the step of entering includes a step of entering a telephone number for specifying an outgoing telephone number that is to be rejected.

5. A method as in claim 1, wherein the step of entering includes a step of entering a portion of a telephone number for specifying a group of outgoing telephone numbers that are to be rejected.

6. A method as in claim 1, wherein the step of entering includes the steps of:

depressing keys on a telephone keypad; and

interpreting the depressed keys as the inputted information.

7. A method as in claim 1, wherein the step of entering includes the steps of:

speaking into a telephone speech transducer; and

interpreting the speech as the inputted information.

8. A method as in claim 1, wherein the step of prompting includes a step of displaying information to the user.

9. A method as in claim 1, wherein the step of prompting includes the steps of:

generating a speech signal in the wireless local loop subscriber unit; and

making the speech signal audible in a telephone speaker.

10. A method as in claim 1, wherein the entered information includes alphanumeric characters comprised of numbers and text.

11. A method as in claim 1, wherein the entered information includes a password.

12. A wireless local loop subscriber unit as in claim 2, wherein said user interface is comprised of a keypad of said telephone, and wherein the information is entered by depressing keys on said telephone keypad.

13. A wireless local loop subscriber unit as in claim 2, wherein said user interface is comprised of a speech recognition function for interpreting a user'"'"'s speech as the inputted information.

14. A wireless local loop subscriber unit as in claim 2, wherein said user interface is comprised of a speech synthesis function for prompting the user to enter information.

15. A wireless local loop subscriber unit as in claim 2, wherein said user interface is comprised of a data port for connecting said wireless local loop subscriber unit to an external data processor.
