Definitions

  • the pilots of the sectors 40r and 42r are identified in the database 21 as boundary sector pilots, while the pilots of the sectors 441 and 461 are identified in the database 31 as boundary sector pilots.
  • the non-boundary cells C l and 04 are shown as being unidirectional cells, although use of any other type of cell configuration (e.g., three- or six-sector) is supported.

Abstract

Procédé et système pour déclencher le transfert intercellulaire à solution de continuité d'un appel provenant d'une cellule de réseau de type CDMA opérant sur une première fréquence vers une cellule opérant sur au moins une seconde fréquence ou dans un réseau de type AMPS. A la différence de la pratique habituelle, ce déclencheur de transfert en secteur limitrophe est activé en deux phases. La première phase de déclenchement se produit lorsque l'ensemble actif d'une unité mobile ne compte que des ondes pilotes identifiées comme ondes pilotes de frontière; c'est-à-dire que le combiné actif comprend un 'ensemble actif de frontière'. Une fois que les exigences pour cette première phase sont remplies, une seconde phase du déclencheur de secteur limitrophe est activée. Dans de la seconde phase, un temps de transmission aller-retour des communications entre l'unité mobile et la station émettrice-réceptrice de base (SB) dont elle est le plus proche est mesuré et lorsque ce temps de transmission aller-retour excède un seuil prédéterminé, les conditions de déclenchement sont remplies et le traitement du transfert se poursuit avec la sélection de la cible et l'exécution du transfert.
