"The present document defines the requirements for Packet Domain interworking between a: a) PLMN and PDN; b) PLMN and PLMN. The present document is valid for a PLMN in A/Gb mode as well as for a PLMN in Iu mode. If text applies only for one of these systems it is explicitly mentioned by using the terms ""A/Gb mode"" and ""Iu mode"". Please note@ that the A interface does not play any role in the scope of the present document although the term ""A/Gb mode"" is used. For inter-working between EPC PLMN and external networks@ the present document is valid for both 3GPP accesses and non-3GPP accesses. The present document also defines@ in clause 17@ the protocol for the Gmb interface@ in clause 20@ the protocol for the SGmb interface@ and in clause 19@ the protocol for the Mz interface. The present document also defines@ in clause 18@ the usage of Radius at the Pk Reference Point between the GGSN and the Presence Network Agent. The term ""Packet Domain"" includes both EPC based and non-EPC based Packet Domains. The present document also defines the specific requirements for rate control related to CIoT optimisations."
