Method of invoking and canceling voice or data service from a mobile unit
First Claim
1. A method of invoking and canceling voice service and data service in a communication system comprising a mobile unit supporting simultaneous voice and data communication having a keypad for receiving and providing user data and a speaker, microphone, and vocoder unit for receiving and providing encoded voice signals, and a terminal equipment unit input for receiving and providing digital data, said communication system further comprising a base station having a vocoder portion for receiving and providing said encoded voice signals and said user data and a modem portion for receiving and providing said digital data and said user data wherein a wireless link couples said encoded voice signal, said user data, and said digital data between said mobile unit and said base station, comprising the steps of:
- receiving at said mobile unit from said terminal equipment input a first modem command within said digital data wherein said first modem command designates a directory number and a request to establish a first voice communication between said mobile unit and said base station; and
receiving said first modem command at said modem portion of said base station and establishing said first voice communication in response to said first modem command such that said encoded voice signals are passed from said speaker, microphone, and vocoder unit over said wireless link to said vocoder portion of said base station and from said vocoder portion of said base station over said wireless link to said speaker, microphone, and vocoder unit.

Abstract
A method of invoking and canceling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

8. A telephone modem apparatus capable of simultaneously providing two connection paths to a telephone network, a first path for providing audible communication, and a second path for providing data communication, said telephone modem apparatus comprising:
-
a mobile unit for receiving a stream of standard digital data from a terminal equipment unit and for transmitting an information signal wherein said mobile unit comprises; a protocol stack for receiving a stream of standard digital data, packetizing said stream of standard digital data, and providing a set of data packets for said second path; a vocoder for receiving audible input, for encoding said audible input, and providing encoded output for said first path; a key pad for receiving user input and providing manual user input command wherein said manual user input commands can designate invocation of communication on said first path or said second path; a radio modulator for receiving and modulating said set of data packets, and said encoded output, said set of data packets for transmission, and for producing said information signal for said first and second paths; a wireless link for conveying said information signal; a base station for receiving said information signal, said base station comprising; a digital signal processor for receiving said set of data packets and providing a corresponding output to said telephone network from said second path; and a vocoder for receiving said encoded output and providing a corresponding output to said telephone network from said first path, said digital signal processor including means for initiating voice communication over said first path in response to a voice request within said set of data packets.

9. A method of invoking and canceling voice service and data service in a communication system comprising a mobile unit supporting simultaneous voice and data communication having a keypad for receiving and providing user data and a vocoder unit for providing an encoded voice signal in response to an input voice signal, and a terminal equipment unit input for receiving and providing digital data, said communication system further comprising a base station having a vocoder portion for receiving and providing said encoded voice signals and said user data and a modem portion for receiving and providing said digital data and said user data wherein a wireless link couples said encoded voice signal, said user data, and said digital data between said mobile unit and said base station, comprising the steps of:
-
receiving at said mobile unit from said terminal equipment input a first modem command within said digital data wherein said first modem command includes a request to establish a first voice communication between said mobile unit and said base station, said mobile unit entering a voice active mode in response to receipt of said first modem command; and receiving said first modem command at said modem portion of said base station and establishing said first voice communication using said vocoder portion of said base station such that said encoded voice signal is passed from said vocoder unit over said wireless link to said vocoder portion of said base station and from said vocoder portion of said base station over said wireless link to said vocoder unit. - View Dependent Claims (10, 11)
