Aiming at the scenario of dramatic increasing of message after earthquakes,especially great or destructive earthquakes,in the earthquake department,in this paper, based on the 12322 earthquake message service platform, we propose a compound priority strategy and multithreading processing mode in order to solve the priority service problem of important businesses and key personnel after the earthquake,and the elastic expansion problem of gateway rate. We also design a self-service exchange service framework to facilitate the operation and service of the platform. Finally,we discuss the limitations of the platform services,and introduce the operation and services of the platform in recent years.
