Abstract

La présente invention concerne un procédé et un terminal permettant d'assurer la transmission d'un message court après le transfert intercellulaire du terminal. Ce procédé comporte plusieurs étapes. Le terminal commence par rétablir un canal utilisé pour transmettre le message court après un transfert intercellulaire, ce qui permet de libérer pour la durée du transfert intercellulaire le canal utilisé pour transmettre le message court. Le terminal utilise alors le canal rétabli pour transmettre le message court qui a été rangé en antémémoire pour la durée du transfert intercellulaire. L'utilisation des modes de réalisation de la présente invention permettra d'améliorer le taux de succès de la transmission de message court après transfert intercellulaire.
