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.

Rejection of incoming and outgoing calls in WLL terminal

A WLL subscriber unit (1) that operates in accordance with a method for establishing a call from a telephone (2) that forms a part of a WLL subscriber unit. The method includes the steps of: (a) dialing a first digit of a telephone number; and (b) detecting the first digit and, in response to detecting the first digit, automatically transmitting a message over an RF channel, the transmitted message being a call origination message having a telephone number portion that contains only the first dialed digit. The method further includes the steps of (c) waiting for a response from the network; (d) when the response is received, determining if at least one additional digit has been dialed; and (e) if yes, transmitting a further message over the RF channel, the transmitted further message being another call origination message having a telephone number portion that contains the first dialed digit and the at least one additional dialed digit that is appended to the first dialed digit. When the network response is received, and if the step of determining if at least one additional digit has been dialed is negative, the method includes the further steps of: (f) determining if the network has accepted the call origination message or rejected the call origination message; (g) if the call origination message is rejected, terminating the call establishment; and (h) if the call origination message is accepted, operating the WLL subscriber unit to connect the call between a user and the called party.
