22. A wireless network that includes a radio access network (RAN) coupled to a core network (CN), the wireless network employing one or both slicing and partitioning of network functionality, the wireless network comprising one or more nodes that include:
communication interface circuitry operable to communicate with user equipment (UEs) and with other nodes in the wireless network; and
processing circuitry operably coupled to the communication interface circuitry, whereby the processing circuitry and the communication interface circuitry are configured to perform operations comprising:
determining, for a user equipment (UE), one or more frequency selection policy parameters (P) related to one or more mobility operations, wherein the frequency selection policy parameters are specific to a protocol data unit (PDU) session for the UE;
sending the PDU session specific frequency selection policy parameters to the UE; and
the one or more frequency selection policy parameters (P) indicate:
one or more index parameters, associated with the PDU session, that, together with information broadcast in a cell, gives the UE instructions on one or more of preferred or allowed camping frequency, preferred or allowed access frequency, or preferred or allowed monitoring frequency.
