In order to avoid system malfunction, the present invention provides a method of enhancing continuous packet connectivity, known as CPC, for a user equipment, known as UE, in a wireless communications system. The method includes the following steps. A control channel less operation function is activated according to a status variable. The status variable is re-determined when a radio link failure occurs, when a radio link control, known as RLC, unrecoverable error occurs or when transmission of UE CAPABILITY INFORMATION fails, so as to deactivate the control channel less operation function. Preferably, the status variable is CPC_HS_SCCH_LESS_STATUS variable, and the control channel less operation function is HS-SCCH less operation, where HS-SCCH is an abbreviation of “Shared Control Channel for HS-DSCH”.
