Architecture enhancements to facilitate communications with packet data networks and applications
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.
The present document also specifies provisioning of UCMF with RACS information.
