[0015] Definitions and Terminology

[0016] The following terms are used throughout the application:

[0017] IS-2000 - refers to the Telecommunications Industry Association (TIA) family of standards that includes core air interface, minimum performance, and service standards. The air interface standard specifies a spread spectrum wireless interface that uses code division multiple access (CDMA) technology to meet the requirements of the third generation (3G) wireless communication system.

[0018] IS-707-A.3 refers to the name IS-707-A.3, "Data Service Option for Spread Spectrum System: AT Command Processing and the RmInterface )” TIA standard. This standard provides requirements for Rm interface, service option method and AT command processing required by mobile station and base station. IS-707-A.3 also includes Service Class 2.0 AT commands from TIA / EIA-592-A required for some components of the system.

[0019] IS-707-A.4 refers to the name IS-707-A.4, "Data Service Opt...

Abstract

Disclosed is a method of transitioning from a facsimile session to a voice session during a call between a wireless user and a facsimile machine. The method comprises sending a procedure interrupt request, sending a procedure interrupt response, sending a procedure interrupt confirmation, negotiating to a voice service option, and then beginning the voice service option.

Description

technical field [0001] This invention relates generally to mobile telephone networks, and more particularly to the use of mobile telephones to communicate with facsimile equipment over a Code Division Multiple Access ("CDMA") CDMA network. Background technique [0002] Mobile phone users are increasingly relying on wireless networks for their personal and business needs. Such needs often include data traffic in addition to voice communications. In order to take advantage of data services, many service providers choose CDMA technology. CDMA is a "spread spectrum" technique, which means that it spreads the information contained in a particular signal of interest over a much larger bandwidth than the original signal. [0003] One data service that is gaining wide acceptance is the ability to send and receive faxes over wireless networks. Facsimile machines are known to allow paper to be sent through the switched telephone system and printed elsewhere. A facsimile device or ...
