Classification: CPC H | IPC H

Claim 7:
8. An apparatus for wireless communications at a user equipment (UE), comprising:
a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the apparatus to:
establish a connection to a legacy core network function of a legacy cellular radio network via a legacy gateway between the legacy cellular radio network and a non-cellular radio network;
identify, for each traffic descriptor in a set of traffic descriptors, a legacy access policy of the legacy cellular radio network identifying a legacy access preference rule for the UE to adopt for connections to the legacy core network function, each legacy access preference rule indicating for the UE to preferentially connect to the legacy core network function via the legacy cellular radio network or a non-cellular radio network for the traffic descriptor and a legacy slice treatment for the traffic descriptor;
establish a connection to a core network function of a cellular radio network via a gateway between the cellular radio network and the non-cellular radio network;
identify, for each traffic descriptor in the set of traffic descriptors, an access policy of the cellular radio network identifying an access preference rule for the UE to adopt for connections to the core network function of the cellular radio network, each access preference rule indicating for the UE to preferentially connect to the core network function via the cellular radio network or the non-cellular radio network for the traffic descriptor and a slice treatment for the traffic descriptor; and
determine, for each traffic descriptor and based at least in part on the legacy slice treatment and the slice treatment and based at least in part on the access policy, to transfer the connection associated with the traffic descriptor to the core network function or to establish an updated connection for the traffic descriptor with the core network function.
