Abstract

An access node (20) of a cellular network receives an information centric networking request of a user equipment (10) for a data object. The access node forwards the information centric networking request to a local gateway (30) associated with the access node (20). The local gateway (30) maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (30). In response to the user equipment (10) moving from a coverage area of the access node (20) to a coverage area of a further access node (21), the access node (20) and the further access node (21) perform a handover procedure. The further access node (21) is associated with a further local gateway (31) maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (31). The handover procedure initiates alignment of the pending interest table and the further pending interest table with respect to at least one entry associated with the user equipment (10).
