Patent ID: 8254321

Claim:
A method for serving high speed downlink shared channel (HS-DSCH) cell change, the method comprising: sending a first measurement report when a signal strength of a target cell approaches a signal strength of a source cell; receiving pre-loaded target cell HS-DSCH configuration information; storing the pre-loaded target cell HS-DSCH configuration information in a memory; sending a second measurement report when a signal strength of the target cell exceeds that of the source cell; monitoring a high speed shared control channel (HS-SCCH) on the target cell based on the pre-loaded target cell HS-DSCH configuration information; receiving an HS-SCCH order from the target cell indicating change of an HS-DSCH serving cell; determining whether a Medium Access Control High Speed/Enhanced High Speed (MAC-hs/ehs) reset is required; and resetting a MAC-hs/ehs entity if it is determined that an MAC-hs/ehs reset is required.
