Abstract
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 discontinuous packet operation is activated according to a CPC_DTX_DRX_STATUS variable. The CPC_DTX_DRX_STATUS variable is re-determined when a radio link failure occurs, when a radio link control unrecoverable error occurs or when transmission of UE CAPABILITY INFORMATION fails, so as to deactivate the discontinuous packet operation. The discontinuous packet operation includes uplink discontinuous transmission, uplink discontinuous reception and downlink discontinuous reception operation.
Claims8
A method of enhancing continuous packet connectivity. abbreviated to CPC, for a user equipment, called LIE hereinafter, in a wireless communications system, the method comprising:
- activating a discontinuous packet operation according to a status variable, wherein the discontinuous packet operation is applied to the UE in a CELL_DCH state;
- initiating a cell update procedure, thereby the UE moving to a CELL_FACH state;
- re-determining the status variable and stopping all related activities of the discontinuous packet operation;
- and
- transmitting a CELL UPDATE message after re-determining the status variable and stopping all related activities of the discontinuous packet operation.
A communications device of a wireless communications system utilized for continuous packet connectivity, abbreviated to CPC, enhancement, the communications device comprising:
- a control circuit for realizing functions of the communications device:
- a central processing installed in the control circuit for executing a program code to operate the control circuit:
- and
- a memory coupled to the central processing unit for storing the program code;
- wherein the program code comprises:
- activating a discontinuous packet operation according to a status variable, wherein the discontinuous packet operation is applied to the UE in a CELL_DCH state:
- initiating a cell update procedure, thereby the UE moving to a CELL_FACH state;
- re-determining the status variable and stopping all activities of the discontinuous packet operation;
- and
- transmitting a CELL UPDATE message after re-determining the status variable and stopping all related activities of the discontinuous packet operation.
