A mobile edge computing method and apparatus are provided. The method which is implemented by a mobile edge computing (MEC) management network element includes: receiving an MEC virtualization resource request sent by a control plane of a target radio access network (RAN), wherein the control plane belongs to the target RAN to which user equipment (UE) is handed over, and the MEC virtualization resource request includes an MEC computing resource requirement of the UE; creating, based on the MEC virtualization resource request, a new virtual machine (VM) on an MEC server for the UE, wherein the new VM is used on the target RAN side after the handover; and sending first information of the new VM to the control plane, wherein the first information includes an ID of the new VM. According to the application, the efficiency of usage of resources during a handover of UE is significantly improved.
