Le procédé comprend les étapes suivantes : un premier appareil de communication acquiert un premier paramètre de chacune des M premières cellules, M étant un nombre entier supérieur ou égal à 1 ; et le premier appareil de communication détermine un premier paramètre d'une seconde cellule selon le premier paramètre de chacune des M premières cellules, l'une quelconque des M premières cellules étant différente de la seconde cellule, et la première cellule et la seconde cellule étant des cellules disponibles pour la communication entre le premier appareil de communication et le second appareil de communication. Par conséquent, même si le premier paramètre de la seconde cellule ne peut pas être obtenu selon les informations associées de la seconde cellule, le premier paramètre de celle-ci peut être obtenu selon des premiers paramètres des autres cellules, de sorte que, selon le premier paramètre de la seconde cellule, le taux de réussite et la qualité du premier appareil de communication communiquant avec le second appareil de communication passant à travers la seconde cellule peuvent être améliorés, et lorsque M est supérieur à 1, la robustesse du premier paramètre de la seconde cellule peut également être améliorée.
