A multi-access edge computing, MEC, platform deployment method, wherein the method comprises: inserting a characteristic root apparatus into a server, the characteristic root apparatus comprising processors (403, 404), a memory and a communications interface adapted to communicate with a communications interface of the server when the characteristic root apparatus is inserted into the server; after the characteristics root apparatus is inserted into the server, running, by the server, characteristic root basic software stored in the characteristic root apparatus, the characteristic root basic software establishing a connection between the server and a cloud server, and initiating, by the server, an authentication process to the cloud server by using the characteristic root apparatus to verify whether the server is trusted, wherein a digital certificate of a user and first authentication information are prestored in the characteristic root apparatus; obtaining, by the server, an image file of a MEC platform component prestored in the characteristic root apparatus; after the authentication succeeds, installing, by the server the MEC platform component by running the image file of the MEC platform component, wherein the MEC platform component comprises local user plane function, LUPF, software and/or application agent, APP agent, software; executing, by the server, an edge policy by using the LUPF software, when the MEC platform component comprises local user plane function, LUPF, software, wherein the edge policy comprises a traffic routing policy and/or a charging policy; and/or implementing, by the server, service governance on a local application by using the APP agent software when the MEC platform component comprises application agent, APP agent, software. inserting a characteristic root apparatus into a server, the characteristic root apparatus comprising processors (403, 404), a memory and a communications interface adapted to communicate with a communications interface of the server when the characteristic root apparatus is inserted into the server; after the characteristics root apparatus is inserted into the server, running, by the server, characteristic root basic software stored in the characteristic root apparatus, the characteristic root basic software establishing a connection between the server and a cloud server, and initiating, by the server, an authentication process to the cloud server by using the characteristic root apparatus to verify whether the server is trusted, wherein a digital certificate of a user and first authentication information are prestored in the characteristic root apparatus; obtaining, by the server, an image file of a MEC platform component prestored in the characteristic root apparatus; after the authentication succeeds, installing, by the server the MEC platform component by running the image file of the MEC platform component, wherein the MEC platform component comprises local user plane function, LUPF, software and/or application agent, APP agent, software; executing, by the server, an edge policy by using the LUPF software, when the MEC platform component comprises local user plane function, LUPF, software, wherein the edge policy comprises a traffic routing policy and/or a charging policy; and/or implementing, by the server, service governance on a local application by using the APP agent software when the MEC platform component comprises application agent, APP agent, software.
