Abstract

Abstract A method of providing call management services to a conventional wireline telephony device (or devices) which receive telephony services by means of a fixed wireless access subscriber unit. Such a subscriber unit (SU) includes a wireless transceiver for communicating with a wireless network and a telephone subscriber line interface which connects to a telephone subscriber line to which the telephony devices are connected. Such a subscriber unit is configured to carry out the following steps. Upon receipt of an incoming message (which typically occurs during call set up of an incoming call) subscriber unit evaluates whether call management services information is present, and if so searches the message, according to the wireless protocol for the CMS information and extracts the CMS information. The SU then interprets the received information, determines what information should be passed to the telephony devices to the SU and produces a message containing the relevant information which is then sent to the telephony devices via the telephone subscriber line. The new message may contain information not present in the original incoming message. This new information is retrieved from a user selected directory stored within the SU. The SU may contain a plurality of transceivers and a plurality of subscriber line interfaces wherein said subscriber unit can effectively act as a wireless key system.
