Abstract

L'invention concerne un procédé et un dispositif de découverte de réseau dans un réseau hybride de rattachement, une station de base et une station de base de commande, qui appartiennent au domaine technique des communications. Le procédé comporte les étapes suivantes: un point de station lance un processus de découverte de réseau en fonction du numéro de repère d'un réseau de destination; lorsque le point de station n'accède pas au réseau de destination correspondant au numéro de repère du réseau de destination dans la limite d'un laps de temps prédéfini et lorsque d'autres points de stations non associés ayant le même réseau de destination que le point de station n'ont pas été trouvés, le point de station passe alors d'un premier port actuellement utilisé pour l'émission à un deuxième port; un nouveau message de compte rendu de point de station est envoyé à un point de station de commande du réseau de destination via le port, de telle sorte que le point de station de commande donne pour consigne à un point de station associé de son réseau d'émettre une balise de découverte, permettant ainsi au point de station de découvrir le réseau de destination en fonction de la balise de découverte. Dans la présente invention, en sélectionnant correctement le numéro de repère d'un réseau de destination et en réveillant à l'avance des points de stations déjà associés qui se trouvent à l'état de sommeil et en faisant en sorte qu'ils découvrent une balise, le processus de découverte de réseau est accéléré.
