Claim 9:
10. A network node for handling User Equipment (UE) capabilities of a UE in a wireless communications network, the network node comprising:
input/output interface circuitry configured to communicate with one or more network nodes of the wireless communications network; and
processing circuitry operatively coupled to the input/output interface circuitry and configured to:
send, to an Access and Mobility management Function (AMF) node, a first indication adapted to indicate whether or not the network node has capabilities to store UE capabilities associated with the UE capability ID;
receive, from the AMF node, a second indication adapted to indicate whether or not UE capabilities associated with a capability identity of the UE, UE capability ID, are available in the AMF node;
decide whether explicit UE capabilities associated with the UE capability ID shall be retrieved from the UE or the AMF node based on the received second indication, which UE capabilities; and
receive, from the AMF node, explicit UE capabilities associated with the UE capability ID, according to any one out of:
when the first indication indicates that the network node has not capabilities to store UE capabilities associated with the UE capability ID, and when the second indication indicates that UE capabilities associated with the UE capability ID are available in the AMF node; or
when the first indication indicates that the network node has capabilities to store UE capabilities associated with the UE capability ID, and when the second indication indicates that UE capabilities associated with the UE capability ID are available in the AMF node, and when the UE capabilities associated with the UE Capability ID is not available in the network node.
