Title (EN) SYSTEM AND METHOD FOR PROVIDING PUSH-TO-TALK FEATURE FOR WIRELESS COMMUNICATION SYSTEMS
(FR) PROCEDE PERMETTANT DE CONFERER UNE FONCTIONNALITE « ALTERNAT » A DES SYSTEMES DE COMMUNICATION SANS FIL
Abstract:
(EN) A method and apparatus for providing push-to-talk functionality to a conventional telephone. An existing key or switch located on a conventional telephone is selected to act as a push-to-talk switch. When a push-to-talk mode of operation is entered, the preselected key or switch is reconfigured to act as a push-to-talk switch. When the preselected key or switch is pressed while the telephone is in the push-to-talk mode, transmission from the telephone is enabled, allowing a user to transmit information to one or more entities. Transmission generally accurs for as long as the preselected key or switch is pressed. When the preselected key is released, the telephone is disabled from transmitting information.
(FR) Cette invention a trait à un procédé permettant de conférer une fonctionnalité alternat à un téléphone classique. On sélectionne une touche ou un commutateur d'un téléphone classique afin de s'en servir comme commutateur de transmission. Une fois entré le mode alternat, la touche ou le commutateur présélectionné est reconfiguré pour servir de commutateur de transmission. Lorsque l'on appuie sur cette touche ou ce commutateur alors que le téléphone se trouve en mode alternat, l'émission à partir dudit téléphone est possible, ce qui permet à l'utilisateur de transmettre une information à une ou plusieurs entités. La transmission a lieu tant que la touche ou le commutateur présélectionné est maintenu appuyé. Lorsque la touche est relâchée, le téléphone n'est plus à même de transmettre d'information.
