System and method for interfacing a standard telephony device to a wireless communication system
First Claim
1. A network switching center for a wireless network in which a terminal originates a call or requests a service by sending a set up message to a base station, said set up message including a routing message for notifying the wireless network that the terminal sends a directory number or feature activation code on a digit by digit basis, and upon establishing a communication link with said base station, sending a directory number or feature activation code on a digit by digit basis, said network switching center comprising;
- a call processor for identifying the presence of a routing message in any incoming call and for processing calls once a complete directory number or service feature activation code is received;
a digit collector and analyzer, responsive to said call processor identifying the presence of a routing message, for analyzing the digits sent by said terminal in order to determine the directory number or service feature activation code sent by said terminal; and
a signaling link for providing said call processor with said the directory number or service feature activation code determined by said digit collector and analyzer.

Abstract
A system for providing fixed wireless access to standard telephony device is disclosed. A subscriber unit comprising a telephony interface for connecting to a standard telephony device, and a transceiver for establishing a communication link with a wireless network is used for providing telephony service to standard telephony device. Dual tone multiple frequency (DTMF) tones produced by said standard telephony device are sent to the wireless network, either directly or indirectly in the form of digit messages corresponding to the dialed digits, after a call set up message is sent. The subscriber unit sends a special set up message which identifies the subscriber unit as a terminal which sends digits on a digit by digit basis. A wireless network component (e.g. an MSC) is configured to identify such a set up message and upon receiving such a set up message collects and analyses digits sent by a subscriber unit on a digit by digit basis in order to provide a service feature or to connect a call.

7. A wireless subscriber unit for communicating with a wireless network comprising:
-
at least one telephony interface for connecting to at least on standard telephony device; at least one transceiver for establishing a communication link with said wireless network; and a controller for controlling said subscriber unit and, responsive to said standard telephony device going off hook in order to make an outgoing call, for instructing said transceiver to establish a communication link and send a routing message which includes a predefined number for differentiating the subscriber unit from terminals which send complete directory numbers in a single message by identifying the subscriber unit as a remote wireless terminal which sends directory number or service activation codes digit by digit. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for using a wireless network for providing wireless telephony service to both a first set of remote terminals and a second set of remote terminals, said first set of remote terminals configured to originate calls by sending a call set up message including a dialed number (directory number or feature activation) upon establishing a wireless link with said wireless network and said second set of remote terminals configured to originate calls by sending a call set up message including a routing message, and then sending a dialed number on a digit by digit basis after establishing a wireless link with said wireless network, said method comprising:
-
(a) establishing a wireless link with a remote terminal which requests a link in order to set up a call; (b) processing said call set up message, said processing step including the step of determining whether said call set up message includes said routing message; (c) responsive to said determining step identifying said routing message, collecting and analyzing the digits sent by said terminal on a digit by digit basis in order to determine the complete dialed number; and (d) processing the call using the dialed number determined by said collecting and analyzing step. - View Dependent Claims (15, 16, 17)

18. A digit collection and analysis system for use in a wireless network wherein remote terminals originate calls using either a first format or a second format, wherein for said first format, a remote terminal sends a set up message which includes a complete directory number or service feature activation code to said wireless network, and for said second format a remote terminal sends a routing message which indicates that the terminal is using said second format and then sends digit messages representing a directory number or service feature request on a digit by digit basis to said wireless network, and wherein said wireless network includes a call processing system for processing calls or feature activation codes upon receipt of a complete directory number or feature activation code, said digit collection and analysis system comprising:
-
a digit analyzer, responsive to said wireless network receiving a call which includes said routing message identifying the call as one following said second format, for collecting and analyzing digits sent on a digit by digit basis, in order to determine the complete directory number or service feature activation code sent by said remote terminal; a signaling link responsive to said analyzer, for sending said complete directory number or service feature activation code to said call processing system for call processing. - View Dependent Claims (19, 20, 21)

22. A fixed wireless subscriber unit which sends the digits of a directory number or a feature activation code on a digit by digit basis to a base station associated with said subscriber unit, said base station connected to the telephone network which provides telephony service to the subscriber unit, said unit comprising:
-
a transceiver; a telephony interface for connecting to a standard telephony device; and a controller for controlling said subscriber unit and, responsive to said standard telephony device going off hook in order to make an outgoing call, for instructing said transceiver to establish a communication link to said base station and to send a routing message which includes a predefined number for differentiating the subscriber unit from terminals which send complete directory numbers in a single message to said base station which instructs said base station to establish a communication link to said telephone network capable of passing digits dialed by said telephony device to said telephone network as said digits are dialed. - View Dependent Claims (23, 24)
