Document Type and Number:
WIPO Patent Application WO/2020/259234
Kind Code:
A1
Abstract:
Provided are an inter-area media service switching method, a server, a system and a storage medium. The method comprises: a first MEC-CDN node acquiring movement 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; in response to determining, according to the movement information, that the user device is pre-moved out of the coverage range of the first MEC-CDN node, the first MEC-CDN node determining a second MEC-CDN node and/or a second MEC platform attached to the second MEC-CDN node, and establishing a connection with the second MEC-CDN node; the first MEC-CDN node migrating state information about the user device onto the second MEC-CDN node; and in response to determining that the user device enters the coverage region of the second MEC-CDN node, the second MEC-CDN node establishing a connection with the user device, so that the user device acquires a media service from the second MEC-CDN node.
