Claim 5:
6. A method performed by an Access and Mobility management Function (AMF) node for handling User Equipment (UE) capabilities of a UE in a wireless communications network, the method comprising:
receiving, from a UE, a capability identity of the UE (UE capability ID);
receiving, 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;
checking whether or not UE capabilities associated with the UE capability ID, are available in the AMF node;
sending, to a network node serving the UE, a second indication indicating whether or not UE capabilities associated with the UE capability ID are available in the AMF node, according to the checking; and
sending to the network node, explicit UE capabilities associated with any one out of the UE capability ID or a UE capability, 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.
