Earthquake and Tsunami Warning System (ETWS); Requirements and solutions; Solution placeholder
The present document is a temporary architectural solution placeholder for Earthquake and Tsunami Warning System (ETWS). This document is to present various architecture and function approaches for 3GPP networks (i.e. GERAN, UTRAN, and LTE) based on the ETWS requirements described in TS 22.168 [2].
NOTE: The contents of this Technical Report led into normative specification of ETWS in related specifications and the contents of this study should be considered out of date.
