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).
