A user equipment (UE), which is operable in EUTRA networks and in NR networks, can perform a capability transfer procedure. The UE can compile EUTRA capabilities of the UE. The UE can further compile NR capabilities of the UE. The UE can transmit one or more UE capability information messages with the compiled EUTRA capabilities and NR capabilities to a base station in an EUTRA network, characterized in that the NR capabilities are compiled subject to a capability size limit, which corresponds to a supported size of a container in a handover message sent on an inter-RAT interface between Evolved Packet Core and 5G Core.

Methods and devices for facilitating an inter-RAT handover

Methods are provided in which a first network node sends a context setup request message to a second network node, the context setup request message not comprising a wireless device (WD) aggregate maximum bit rate (AMBR) value associated with a wireless device, determines that it has not previously provided the WD AMBR value to the second network node in the context setup request message, and then sends a resource setup request message to the second network node, the resource setup request message comprising the WD AMBR value associated with the wireless device. Related network nodes and computer program products are also provided.
