La présente invention concerne le domaine technique des communications mobiles et, particulièrement, concerne un procédé pour déterminer un numéro de port et un NodeB E-UTRAN (eNB). Le procédé consiste en ce que : un premier eNB détermine d'établir une interface X2 avec un second eNB ; le premier eNB acquiert les adresses IP des deux extrémités d'une liaison de protocole SCTP (Stream Control Transmission Protocol) correspondant à l'interface X2 (101), les adresses IP des deux extrémités comprenant l'adresse IP du premier eNB et l'adresse IP du second eNB ; le premier eNB juge si une relation correspondante entre les adresses IP des deux extrémités et la liaison SCTP établie est mémorisée ou non, et obtient un résultat de jugement (102) ; et le premier eNB établit la liaison SCTP conformément au résultat de jugement (103). En utilisant la présente invention, il n'est pas nécessaire de configurer au préalable un numéro de port SCTP cohérent pour les eNB aux deux extrémités où l'interface X2 est établie, et par conséquent les contraintes de configuration des paramètres de réseau sont réduites.
