(54) Title: POLICY COMMUNICATION VIA CONTROL PLANE SIGNALING (57) : Techniques are described herein to communicate policy information and policy information requests between user equipments (UEs) and a core network using control plane signaling. In some exam- Core Network ples, non-access stratum (NAS) messages may be used to communicate 225-a policy information requests from a UE to the core network. Similarly, NAS messages may be used to communicate up-to-date policy informa- 30 Policy information tion from the core network to the UE. In some examples, the core net- work may include number of functions to manage the communication of policy information with the UE. In some examples where the UE is roaming away from its home network, the core network may engage in additional signaling to pass policy information to the UE. 130-a 115-b 310 NAS Policy Request 335 45 120-b 3.0 Non-access Stratum \" bower Layers 25 0 320 W O 20 18/ 175 0 29 Al FIG. 3 300 [Continued on next page] WO 2018/175029 Al MIDEDIMODOEMMEMMOMOINIENIMOMMOVOIS Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(H)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: — with international search report (Art. 21(3))
