Due to the initiative of communication mode and the broad coverage of users, SMS plays a vital role in releasing emergency early warning. However, the SMS platform built by the meteorological department has limitations in release timeliness, coverage, and positioning release, which cannot meet the rapid and accurate release of early warning information. In this paper, combined with the China Mobile big data platform, a technical solution for the targeted release of early-warning SHORT messages is based on the cellular communication principle. Taking the implementation of this scheme in the Ningxia region as an example, critical technologies such as system layout, data docking, target user screening and targeted release strategy are highlighted. The solution can effectively improve the pertinence and effectiveness of the emergency early warning information.
