2. A method implemented by a network device functioning as a point of attachment (PoA) in an information-centric networking (ICN) network, the method comprising:receiving, from a user equipment (UE), a registration request for network registration;
retrieving, from the registration request, access context of the UE which identifies the UE;
updating one or more data structures in the PoA to include the access context and a default priority set for the UE, wherein the default priority is a highest priority when the UE is the last UE to register and is associated with a forwarding priority in the ICN network;
sending, to the UE in response to the registration request, a routing prefix with a name of the PoA, wherein the routing prefix is for routing interests of a service of the PoA; and
sending, to a second network device functioning as a heterogeneous access point (H-AP), a message notifying the H-AP of the registration request from the UE, wherein the PoA has registered with the H-AP.
