Patent

CA 2571423

A method and apparatus are provided for defining terminal behavior in a case where the terminal detects that it cannot receive the HS-DSCH from a serving cell reliably when the DCCH is mapped to HS-DSCH (e.g. does not receive any radio link control (RLC) acknowledged mode feedback for the uplink measurement reports or in general the common pilot channel (CPICH) level drops too low in the serving HS-DSCH cell). The terminal is autonomously moved to a cell forward access channel (CELL_FACH) state and uplink signaling is initiated on a random access channel (RACH) to inform a network node and ask for HS-DSCH re- establishment in a suitable cell, or setting up a regular R'99/R'5 DPCH in order to restore the RRC signaling connection in the CELL_DCH state.

L'invention concerne un procédé et un appareil permettant de définir le comportement d'un terminal, au cas où ledit terminal détecte qu'il ne peut pas recevoir fiablement HS-DSCH d'une cellule de desserte, lorsque DCCH est apparié à HS-DSCH (par exemple, ne reçoit aucune rétroaction de mode de reconnaissance de contrôle de liaison radio pour les rapports de mesure de liaison montante ou en général, le niveau du canal pilote commun (CPICH) s'abaisse trop dans ladite cellule HS-DSCH de desserte). Le terminal se déplace de façon autonome vers un état de voie d'accès avancée de cellule (CELL FACH) et la signalisation montante est initiée sur une voie d'accès aléatoire (RACH) afin d'informer un noeud de réseau et de demander le rétablissement HS-DSCH dans une cellule appropriée ou d'établir R'99/R'5 DPCH régulier en vue de restaurer la connexion de signalisaiton RRC dans l'état CELL DHC.
