Abstract

Two-way radio communications services are modeled after single channel services where there is a single originator and one or more consumers of the information to be sent (e.g., private call and group call). With the recent advances in speaker independent voice recognition and subsequent voice to text and text to voice conversions it is possible to offer additional radio call types and services.

DUAL MODE RADIO

by Bill Foster and Patrizia Loborzo

BACKGROUND

  Two-way radio communications services are modeled after single channel services where there is a single originator and one or more consumers of the information to be sent (e.g., private call and group call). With the recent advances in speaker independent voice recognition and subsequent voice to text and text to voice conversions it is possible to offer additional radio call types and services.

PROBLEM

  On occasion, when a user is engaged in one RF call, the user is then unable to engage in a second RF call at the same time. If a user is engaged in a first call (e.g., a group call) that may not be as important to the user as a second call (e.g., an emer- gency call), the user is unable to receive the second call and may not even know that the second call exists, and consequently the second call may be bus- ied to the call's originator.

  Call waiting provides for a way to allow a user to participate in one call or another call, but not both calls simultaneously. Further, call waiting is not feasible for a group call. Three-way call allows for two calls to become one, but when the two calls and parties are totally unrelated, three-way call does not provide a reasonable solution.

SOLUTION

  A method of using text in a dual-mode radio allows a user to transmit and/or receive in each of two calls simultaneously in one radio.

  The user may be able to receive two separate calls simultaneously. If the mobile user is currently

involved in a voice call, ~;a second call can proceed simultaneously via a text displ...
