context: No summary provided for the three items above. For the other charging-related sumamries, see individual summaries below. Input expected from S5 rapporteur. Summary based on the input provided by Nokia in SP-170765. This work item provides solutions for charging from SMS-SC, the SMS deliveries using T4 (between MTC-IWF and SMS-SC) according to TS 23.682 "Device Triggering" and "MSISDN-less MO-SMS via T4" functionalities. The Rel-11 SIMTC had the corresponding charging done under SIMTC-CH (although re-using the Feature description SP-120848) with limited scope (e.g. Device Trigger was not covered), and the charging SMS from MME was introduced. The Rel-12 SMS-SC-CH (under CH2 Feature) introduced Offline charging from SMS-SC and completed some charging aspects of Rel-11 SIMTC (Device trigger). The Rel-14 CH14-SMST4: - covers some charging part of Rel-12 feature MTCe-SDDTE (Device trigger replace/recall), but also introduces online charging for Device trigger. - covers the charging part of
description: A Study Item in 3GPP standardization focusing on System Improvements for Machine Type Communication (SIMTC) to enhance charging functionalities and SMS deliveries using T4 between MTC-IWF and SMS-SC.
explanation: The text refers to a 'Study Item' within the 3GPP standardization process, which is dedicated to exploring and improving SIMTC functionalities related to charging and SMS delivery.
