Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and device for executing cell update while in a Cell_FACH state.

SOLUTION: While high speed downlink packet access (HSDPA) transmission is received in a Cell_DCH state a cell update trigger event is detected using individual high speed downlink shared channel (HS-DSCH) radio network temporary identification (RNTI). The cell update trigger event includes at least one of a radio link failure or a radio link control (RLC) unrecoverable error clears the radio network temporary identification (RNTI) received from a source cell and reads system information from a target cell. On the basis of the common HS-DSCH system information included in the system information high speed downlink shared channel (HS-DSCH) medium access control (MAC-ehs) entity is reset and TRUE is set for an HS-DSCH reception variable thereby enabling reception of the HS-DSCH.
