Methods and apparatus are described for configuring desired network capabilities in a service-based network, including a method for a UE to initiate a network capability based registration to configure its desired network capabilities, a method for UEs to initiate a network capability based registration update when UEs are already registered to the network and want to dynamically re-configure their network capabilities, and a method for a network capability based UE configuration update, which allows NFs or ASs to initiate updating the network capabilities in a network slice for the UE.
