L.4 C-SGN

23.4013GPPGeneral Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) accessRelease 18TS

The C-SGN (CIoT Serving Gateway Node) is a combined node EPC implementation option that minimizes the number of physical entities by collocating EPS entities in the control and user planes paths (e.g. MME, S-GW, P-GW), which may be preferred in CIoT deployments. The external interfaces of C-SGN implementation option are the interfaces of the respective EPC entity supported by the C-SGN, such as MME, S-GW, and P-GW.

A C-SGN supports sub-set and necessary functionalities compared with the existing EPS core network elements and also supports at least some of the following CIoT EPS Optimisations:

– Control Plane CIoT EPS Optimisation for small data transmission.

– User Plane CIoT EPS Optimisation for small data transmission.

– Necessary security procedures for efficient small data transmission.

– SMS without combined attach for NB-IoT only UEs.

– Paging optimisations for coverage enhancements.

– Support for non-IP data transmission via SGi tunnelling and/or SCEF.

– Support for Attach without PDN connectivity.

Annex M (informative):
Functions and procedures over NB-IoT RAT

In the case of conflict between the information in this Annex and other information in the main body of the present document, the information in the main body takes precedence.

The following tables list the functions and procedures that are:

– Supported or not supported over NB-IoT RAT, including whether for CP CIoT EPS Optimisation only, UP CIoT EPS Optimisation only or both.

– Optional for the UE and/or network when using NB-IoT RAT.

NOTE: The tables M-1 to M-5 are ordered by clause number according to the present specification. The table M-6 is ordered by clause number according to TS 23.682 [74]. The notation "CP/UP/Both" indicates whether a particular item is supported for CP CIoT EPS Optimisation only, UP CIoT EPS Optimisation only or both.
