Method and apparatus for stopping data/packet transmission

A method of controlling a network resource during packet transmission by a user equipment (UE) to a network, the method comprising:

• transmitting a predetermined bit pattern to the UE after inserting the predetermined bit pattern into a frame of downlink (DL) dedicated physical channel (DPCH) by the network;
• detecting the predetermined bit pattern by the UE;
• and
• stopping packet transmission through the allocated network resource by the UE.

An emergency stop procedure during transmission of data through CPCH by a UE to a UTRAN comprising:

• providing a CPHY-CPCH-Estop-REQ primitive from a node B radio resource control layer (RRC) to a Node B physical layer;
• sending a CPCH-Estop-Command from the node B physical layer to a UE physical layer;
• sending a CPHY-CPCH-Estop-IND primitive from the UE physical layer to the UE-RRC upon reception of the CPCH-Estop-Command;
• providing a CPHY-CPCH-Estop-Resp primitive from the UE-RRC to the UE physical layer in reply to the CPHY-CPCH-Estop-IND primitive;
• and
• executing CPCH emergency stop by the UE physical layer.

A method of sending a frame for a dedicated physical channel, wherein the improvement comprises:

• sending the frame, the frame having a plurality of slots, each slot having a first prescribed number of bits for dedicated physical control channel (DPCCH) and a second prescribed number of bits for dedicated physical data channel (DPDCH), wherein
• at least one of the DPCCH or DPDCH includes a prescribed pattern for stopping common packet channel (CPCH) transmission;
• detecting the prescribed pattern;
• and
• stopping the CPCH transmission.

A base station, comprising:

• means for receiving packet transmission through a common packet channel CPCH;
• means for detecting an abnormal condition in a network;
• and
• means for transmitting a frame having a command to stop the CPCH transmission when the abnormal condition is detected, wherein the frame includes a plurality of slots, each slot having a first prescribed number of bits for a dedicated physical control channel (DPCCH) and a second prescribed number of bits for a dedicated physical data channel (DPDCH), wherein a prescribes pattern corresponding to the command for stopping the CPCH transmission is provided within the frame of at least one of the DPCCH of DPDCH.

A method for emergency stop of a packet transmission on a common packet channel (CPCH) is a communication system, the method comprising:

• transmitting a corresponding packet through an uplink (UL) CPCH by a user equipment (UE);
• sending a predetermined bit pattern of [1111] to the user equipment (UE) through a downlink (DL) dedicated physical control channel (DPCCH);
• detecting the predetermined bit pattern of [1111] of an emergency stop command by the UE;
• and
• stopping the packet transmission through the CPCH by the UE upon detection.
