Patent

CA 2679228

Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the mobile device can monitor multiple base stations determining timing information related thereto and access scheduling request channels for the base stations. When ready for handover, the mobile device can request data resources over the scheduling request channel using the appropriate timing information.

La présente invention concerne des systèmes et des méthodologies qui facilitent le transfert de communications de dispositif mobile dans un réseau sans fil d'un poste de base source à un poste de base cible sans utiliser un canal d'accès aléatoire (RACH). A cet égard, le dispositif mobile peut surveiller plusieurs postes de base déterminant des informations temporelles en rapport avec ceux-ci et accéder à des canaux de requête de programmation pour les postes de base. Quand le dispositif mobile est prêt pour le transfert, il peut demander des ressources de données sur le canal de requête de programmation en utilisant les informations temporelles appropriées.
