Method, apparatus, and system for detecting terminal device anomaly

A method for detecting a terminal device anomaly, comprising:

• obtaining, by a network node, abnormal event triggering information regarding a terminal device, wherein the abnormal event triggering information comprises at least one of the following:
• information indicating an abnormal event trigger condition for the terminal device or configuration information regarding an abnormal event trigger;
• and
• sending, by the network node, the abnormal event triggering information to a packet data network gateway (PGW), wherein the abnormal event triggering information is used by the PGW to determine whether an anomaly has occurred in the terminal device.

An apparatus of a packet data network gateway (PGW) for detecting a terminal device anomaly, wherein the apparatus comprises:

• a processor and a memory, the processor being configured to communicate with the memory, and to invoke execution instructions in the memory to perform the following operations:
• obtaining abnormal event triggering information regarding a terminal device, wherein the abnormal event triggering information comprises at least one of the following:
• information indicating an abnormal event trigger condition for the terminal device or configuration information regarding an abnormal event trigger;
• and
• determining, according to the abnormal event triggering information, that an anomaly has occurred in the terminal device.
