Abstract: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMF. After the UE initiates a first registration request, the initial AMF may retrieve a candidate AMF list and selects a target AMF to serve the UE. The initial AMF generates a 5G-GUTI for the UE, based on the selected target AMF. The initial AMF requests the UE to initiate a second registration request, by using the generated 5G-GUTI. With the solutions provided in this disclosure, the message interactions between the UE and the target AMF are integrity protected and/or ciphered, without the need to upgrade the UE and without using an indirect connection of the core network.

Abstract: A packet delay budget (“PDB”) improves quality of service (“QoS”) by providing an accurate delay of packets over a network. PDB includes an access network PDB (“AN PDB”) and a core network PDB (“CN PDB”). Because the PDB can change based on network load, the PDB value is more accurate when the CN PDB is dynamically determined. The dynamic CN PDB can be calculated at the basestation or at the user plane function (“UPF”) and an indication of the dynamic PDB indication can be sent between the basestation and/or the UPF.

Abstract: A wireless communication method for use in network slice-specific authentication and authorization function is disclosed.

Abstract: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMF. During a UE registration procedure, the initial AMF generate a 5G-GUTI for the UE and retrieves a candidate AMF list. The initial AMF sends the generated 5G-GUTI (or 5G-S-TMSI), the candidate AMF list, and a full registration request message to the (R)AN for storage and subsequent use. The initial AMF, once determines an AMF re-allocation is needed, instruct the UE to re-start the registration procedure with the core network, by using the generated 5G-GUTI. The (R)AN selects the target AMF, and forward the stored full registration request message to the target AMF to complete the registration.
