Abstract

L'invention concerne un procédé de sélection de liaison et un appareil associé. Le procédé consiste : lors de la détection d'une demande de démarrage de liaisons multiples, à déterminer des informations d'état de multiples liaisons de communication à connecter ; à sélectionner, en fonction des informations d'état, au moins deux liaisons de communication cibles parmi les multiples liaisons de communication ; et à connecter les deux liaisons de communication cibles ou plus. Des modes de réalisation de la présente invention aident à améliorer la rationalité et l'efficacité de sélection de liaison, améliorent la vitesse de transmission de données et réduisent le retard de réseau.
