As the name implies, the detection rule is used to complete the detection and matching of the data packet, and the execution rule is used to indicate the processing required to match the data message of the PDR.

After the control plane and the user plane are separated, the PGW User plane (PGW-U) is grouped. The PGW Control Plane (PGW-C) instructs the PGW-U to perform actions such as matching, control (eg, QoS), reporting, and forwarding through the four types of rules described above.
