Apparatus, and an associated method (110), selectively transmits packets of message data between a sending (12) and a receiving station (14). When a packet of message data (22) is received at a receiving station (14), the receiving station (14) acknowledges reception thereat of the packet with an acknowledgment response signal (42), transmitted back to the sending station (12). If the sending station (12) fails to detect an acknowledgment response signal (42), a packet of activity-request data (72) is sent to the receiving station (14). If the receiving station (14) fails to acknowledge reception of the packet of activity-request data, a determination is made that the receiving station would be unlikely to be able to receive an additional packet of message data (22). A channel to be used to transmit the packet of message data (22) can instead be reallocated for other purposes.

La présente invention concerne un appareil et son procédé associé (110) d'émission sélective de paquets de données de messages entre une station émettrice (12) et une station réceptrice (14). Lorsqu'un paquet de données (22) de messages est reçu par une station réceptrice (14), la station réceptrice (14) en accuse réception par un signal (42) réponse d'accusé de réception renvoyé à la station émettrice. Si la station émettrice (12) n'est pas capable de détecter un signal (42) réponse d'accusé de réception, un paquet de données de requête d'activité (72) est envoyé à la station réceptrice. Si la station réceptrice n'est pas capable d'accuser réception du paquet de données de requête d'activité, le système estime que la station réceptrice est dans l'incapacité de recevoir des paquets supplémentaires de données (22) de messages. Un tel canal destiné à servir pour l'émission du paquet de données (22) de messages peut dans ce cas être réaffecté à d'autres besoins.
