Claim 14:
15. An Access and Mobility management Function (AMF) node for handling User Equipment (UE) capabilities of a UE in a wireless communications network, the AMF 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:
receive from a UE, a capability identity of the UE (UE capability ID);
receive from a network node, a first indication indicating whether or not the network node has capabilities to store UE capabilities associated with the UE capability ID;
check whether or not UE capabilities associated with the UE capability ID, are available in the AMF node;
send to a network node serving the UE, a second indication adapted to indicate whether or not UE capabilities associated with the UE capability ID are available in the AMF node, according to the checking; and
send to the network node, explicit UE capabilities associated with any one out of: the UE capability ID or a UE capability Enquiry, 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.
