Title
(EN) PACKET CHANNEL FEEDBACK
(FR) RETOUR D'INFORMATION PAR CANAL PAQUETS
Abstract
(EN)
A method is disclosed for improving the efficiency of the packet data channel by providing means for interrupting transmissions from or to a first mobile station so as to allow a short message to be communicated between the communication system and a different mobile station. The packet channel feedback information includes several flags: Busy-Reserved/Idle (BRI); Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.
(FR)
L'invention concerne un procédé permettant d'améliorer l'efficacité du canal paquets de données grâce à un système capable d'interrompre les transmissions provenant du ou destinées à une station mobile afin de faire passer un message bref entre le système de communication et une autre station mobile. L'information de retroaction par canal paquets comprend plusieurs drapeaux: occupé-réservé/libre (BRI), reçu/non reçu (R/N), écho partiel (PE) et qualificateur d'écho partiel (PEQ). Le PEQ permet au système de communication d'interrompre la transmission destinée à une station mobile afin d'envoyer un message bref à une autre station. En réglant le PEQ sur diverses valeurs, une station mobile peut déterminer si la mise à disposition du sous-canal a été temporairement interrompue et si celui-ci a été réattribué à une autre station.
