A method for use in a communication system comprising a content delivery network comprising an edge tier of servers located on mobile platforms served by wireless communication links of the communication system and at least one terrestrial tier of servers distributed geographically within the communication system, the method comprising: receiving a request for a media content item from a device within a mobile platform served via a wireless communication link of the communication system; determining an identity of a mobile edge server (170-a) located on the mobile platform based at least in part on a network address of the device associated with the request; determining whether the media content item is stored on the mobile edge server; when the media content item is stored on the mobile edge server, redirecting the request for the media content item to the mobile edge server; when the media content item is not stored on the mobile edge server, determining whether the media content item is stored on a first terrestrial server (522-a) of a first tier of servers of the at least one terrestrial tier of servers, the first terrestrial server (522-a) being coupled with a first access node (110-d-1) serving the mobile platform and associated with the mobile edge server for the content delivery network; when the media content item is stored on the first terrestrial server (522-a) of the first tier of servers, redirecting the request for the media content item to the first terrestrial server (522-a); determining that the mobile platform has transitioned to being served by a second access node (110-d-3) while the mobile platform is in transit; and updating the association of the mobile edge server for the content delivery network to be associated with a second terrestrial server (522-b) coupled with the second access node (110-d-3). receiving a request for a media content item from a device within a mobile platform served via a wireless communication link of the communication system; determining an identity of a mobile edge server (170-a) located on the mobile platform based at least in part on a network address of the device associated with the request; determining whether the media content item is stored on the mobile edge server; when the media content item is stored on the mobile edge server, redirecting the request for the media content item to the mobile edge server; when the media content item is not stored on the mobile edge server, determining whether the media content item is stored on a first terrestrial server (522-a) of a first tier of servers of the at least one terrestrial tier of servers, the first terrestrial server (522-a) being coupled with a first access node (110-d-1) serving the mobile platform and associated with the mobile edge server for the content delivery network; when the media content item is stored on the first terrestrial server (522-a) of the first tier of servers, redirecting the request for the media content item to the first terrestrial server (522-a); determining that the mobile platform has transitioned to being served by a second access node (110-d-3) while the mobile platform is in transit; and updating the association of the mobile edge server for the content delivery network to be associated with a second terrestrial server (522-b) coupled with the second access node (110-d-3). <EOS>
