The enhance mechanism of RRC connection release in LTE system

Signaling storm happened frequently around the world in the recent years, which caused the network congestion, and then affected the user´s normal communication. The signaling storm resulted from the large number of signaling consumption that were used for frequent RRC connections. In this paper, we presented a RRC connection release control method to control the user´s frequent connection in the case of network signaling overload. The simulation results showed that the improved method to control RRC connection release could real-time control the network connection signaling below a certain level and avoid the occurrence of signaling storm.
