The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.

1 Scope
The present document specifies architecture enhancements to facilitate communications with packet data networks and
applications (e.g. Machine Type Communication (MTC) applications on the (external) network/MTC servers)
according to the use cases and service requirements defined in TS 22.368 [2], TS 22.101 [3], and related 3GPP
requirements specifications. Both roaming and non-roaming scenarios are covered.
The present document also specifies transmission of non-IP data via SCEF for the CIoT EPS Optimization.
The present document also specifies the interface between the SCEF and the SCS/AS.
