Patent ID: 8570953

Claim:
A method of improving a high-speed downlink operation in CELL_FACH state for a network terminal of a wireless communications system, the network terminal wirelessly communicating with a user equipment, hereinafter called UE, the network terminal and the UE both supporting the high-speed downlink operation in CELL_FACH state, the method comprising: using a first function but not using a second function when the UE initiates a radio resource control establishment procedure, wherein the first function is used for allocating a dedicated HS-DSCH radio network transaction identifier, hereinafter called H-RNTI, to the UE during a radio resource control (RRC) establishment procedure, so as to manage the UE to perform the high-speed downlink operation in CELL_FACH based on the dedicated H-RNTI, and the second function is used for not allocating the dedicated H-RNTI to the UE; and wherein the first function comprises: setting a New H-RNTI information element, hereinafter called IE, with the dedicated H-RNTI; including the New H-RNTI IE in an RRC CONNECTION SETUP message; and sending the RRC CONNECTION SETUP message to the UE.
