Abstract: A user equipment (UE) context migration management method applied to a mobile edge platform for managing a UE context of a mobile communication device is provided. An embodiment of the UE context migration management method includes: receiving at least one migration request for the UE context; calculating a first difference data corresponding to the UE context in response to the at least one migration request, wherein the first difference data represents a difference between the UE contexts obtained in two consecutive UE context retrieving operations corresponding to the at least one migration request; and transmitting the first difference data to the neighboring mobile edge platform to request the neighboring mobile edge platform to perform a migration operation of the UE context based on the first difference data.

Abstract: A user equipment (UE) context migration management method applied to a mobile edge platform (MEP) for managing a UE context of a mobile communication device is provided. An embodiment includes: receiving a migration completion indication of a mobile communication device; obtaining source platform information corresponding to the mobile communication device according to the migration completion indication, wherein the source platform information at least includes a location information of a source MEP; and transmitting a first request to the source MEP according to the source platform information to obtain an pointer information of the UE context of the mobile communication device from the source MEP, wherein the pointer information at least indicates a location where the UE context of the mobile communication device locates and the location information of the source MEP.
