Abstract: Embodiments of the present invention relate to the communications field, and provide an MEC platform handover method, apparatus, and system. The method includes: receiving a handover notification sent by a handover notification device, where the handover notification device is a source access network device of to-be-handed-over UE or a target MEC platform of the to-be-handed-over UE; determining a TEID of the to-be-handed-over UE according to the handover notification; obtaining context of the to-be-handed-over UE according to the TEID of the to-be-handed-over UE; and sending the context to the target MEC platform. The present invention resolves a problem that provision of application data by an MEC platform to UE is interrupted when the UE is being handed over between access network devices, thereby providing continuous services to the UE. The present invention is applicable to a handover between MEC platforms.

Abstract: A routing rule obtaining method, device, and system are provided. The method is applied to an MEC system and performed by a data bus controller, including: obtaining service information of at least one service in the MEC system, where service information of each service includes a service type and a service identity; generating a routing rule according to the service information of the at least one service, where the routing rule is used to indicate at least one path through which a data packet can pass; and sending the routing rule to a data bus, so that the data bus forwards, according to the routing rule, a received data packet to a service corresponding to the data packet. The service information of each service is dynamically obtained, so as to update a path indicated in a routing rule.

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for detecting a terminal device anomaly. A PGW obtains abnormal event triggering information regarding a terminal device, and the abnormal event triggering information includes at least one of the following: an abnormal event condition for the terminal device or configuration information regarding an abnormal event trigger; and the PGW determines, according to the abnormal event triggering information, that an anomaly has occurred in the terminal device, so that when the terminal device has a behavior (for example, the terminal device carries out a service related behavior beyond a specified range or the terminal device is damaged and abnormal) that is indicated by the abnormal event triggering information, the PGW can detect the anomaly of the terminal device, and an administrator of the terminal device can obtain anomaly information regarding the terminal device from the PGW node.
