A mobile wireless terminal (MWT) (206) receives IP packets (404) destined for a ground network (234) in a predetermined sequence order. The MWT (206) fragments each of the IP packets into many smaller packet fragments (406), appends identifying information to each of the packet fragments (408), and transmits the packet fragments in parallel with one another (416) over concurrently operating satellite channels (240a-240n). A receiving station (180) receives the packet fragments (904) transmitted by the MWT (206). The receiving station (180) forwards the received packet fragments to a ground controller (232) over a network connection, based on the identifying information appended to the packet fragments. The ground controller (232) combines the packet fragments (908) into reconstructed IP packets based on the identifying information appended to the fragments. The ground controller (232) also sequences the reconstructed IP packets (1006) in the predetermined sequence order based on the identifying information. The ground controller (232) forwards the reconstructed IP packets (1008) in the correct sequence order to the destination ground network (234). The same sequence of events occur in the opposite direction as well i.e., from the ground controller to the MWT (206).

Un terminal sans fil mobile (MWT) (206) reçoit des paquets de protocole Internet (IP) (404) destinés à un réseau terrestre (234) selon un ordre séquentiel prédéterminé. Ce terminal (MWT) (206) fragmente chacun de ces paquets en un nombre important de fragments plus petits (406), annexe une information d'identification à chacun de ces fragments de paquets (408) et transmet ces derniers en parallèle les uns par rapport aux autres (416) au moyen de voies satellites fonctionnant simultanément (240a-240n). Une station réceptrice (180) reçoit ces fragments de paquets (904) transmis par le terminal MWT (206). Cette station réceptrice (180) achemine les fragments de paquets reçus jusqu'à un contrôleur terrestre (232) par l'intermédiaire d'une connexion réseau en fonction de l'information d'identification annexée à ces fragments. Ce contrôleur terrestre (232) combine ces fragments de paquets (908) en paquets de protocole Internet reconstitué en fonction de l'information d'identification annexée à ces fragments. Ce contrôleur terrestre (232) met également en ordre ces paquets reconstitués (1006) selon la séquence prédéterminée en fonction de cette information d'identification. Ce contrôleur terrestre (232) achemine les paquets reconstitués (1008) dans la séquence correcte jusqu'au réseau terrestre de destination (234). La même suite d'événement apparaît également dans le sens contraire, à savoir, depuis le contrôleur terrestre jusqu'au terminal MWT (206).
