|Publication Date:||1 January 2021|
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.
