1. An inter-area media service switching method, comprising:
acquiring, by a first Mobile-Edge Computing (MEC)-Content Delivery Network (CDN) node, mobile information about a user device from a core network; wherein the user device establishes a connection with the first MEC-CDN node, and acquires a media service from the first MEC-CDN node;
determining, by the first MEC-CDN node, in response to determining that the user device is pre-moved out of a coverage range of the first MEC-CDN node according to the mobile information, a second MEC-CDN node and/or a second MEC platform to which the second MEC-CDN node is attached, and establishing a connection with the second MEC-CDN node;
migrating, by the first MEC-CDN node, state information about the user device onto the second MEC-CDN node; and
establishing, by the second MEC-CDN node, in response to determining that the user device enters a coverage area of the second MEC-CDN node, a connection with the user device, to enable the user device to acquire the media service from the second MEC-CDN node;
wherein determining the second MEC-CDN node and/or the second MEC platform, comprises:
selecting, by an MEC management platform, the second MEC-CDN node and/or the second MEC platform according to an interest area of the user device, and acquiring, by the first MEC-CDN node, information about the second MEC-CDN node and/or the second MEC platform from the MEC management platform; and/or
determining, by the first MEC-CDN node, the second MEC-CDN node and/or the second MEC platform, according to a management strategy configured by a CDN node management platform where the first MEC-CDN node is located.
