Abstract

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.
