Abstract

Methods and apparatuses maintain user-plane session status information of user equipment in an edge cloud. Upon determining that a handover of UE at a network edge has occurred, a status-information-acquisition mechanism is added to a handover signaling chain. The status-information-acquisition mechanism triggers providing UP session status information of the UE to a target gateway, which intermediates traffic between the target base station and a network device outside the edge cloud. The UP session status information of the UE is then used by the target gateway to determine UE-related data to be reported to the network device for execution of a function such as legal interception or charging.
