Service processing method and system in 5G edge computing scene

The invention discloses a service processing method and system in a 5G edge computing scene, and the method comprises the steps that after an application is registered in an MEP platform, the MEP platform synchronizes a shunting rule to a ULCL-UPF, synchronizes an identification rule to an SMF, and synchronizes application information to a GSLB; a 5G core network receives a registration request initiated by a terminal, and the SMF selects an anchor point UPF according to terminal information and establishes a PDU session; and the anchor point UPF detects a location query DNS request initiated by an application client, dynamically inserts the UPF-ULCL, selects the location service IP of the MEC platform as a response to the location query DNS request, and returns the response to the application client. And the application client initiates a location query service request according to the location service IP, the location query service request is scheduled to the location service application in the MEC platform
