Abstract

L'invention concerne un procédé d'accès et un terminal d'accès pour une liaison de communication par satellite, lesquels se rapportent aux domaines techniques des communications par satellite et des communications mobiles cellulaires sans fil. Le procédé comprend les étapes suivantes : un AT dans un système cellulaire reçoit des signaux de cellules; et l'AT détermine, lorsque l'AT reçoit des signaux d'une pluralité de cellules comprenant des cellules dont des types de liaison de porteuse sont des types de porteuse par liaison par liaison satellite et des types de porteuses par liaison filaire et si les signaux des cellules de type porteuse par liaison satellite sont les plus forts parmi les signaux des multiples cellules, que les cellules de type porteuse par liaison filaire ne répondent pas à des conditions établies, et a accès aux cellules de type porteuse de liaison satellite, les conditions établies comprenant: des signaux de cellules supérieurs ou égaux à un seuil de rapport signal/bruit d'accès minimum , et des informations de charge de cellule qui ne sont pas surchargées. La solution technique optimise la maximisation des capacités de ressources de porteuse d'accès par liaison satellite, et permet aux ressources de porteuse d'accès par liaison satellite d'être raisonnablement appliquées.
