Small data optimized radio access network signaling/control design

The fast adoption of smart phone triggers the migration of tremendous internet applications from desktop to mobile terminal, as well as various inherently mobile oriented applications. Among them, Instant Message (IM) represents a large portion of applications. Unlike over traditional wired network, IM brought a great trouble to the mobile network called “signaling storm” due to its small data dominated traffic profile. This paper conducts a comprehensive analysis on the signaling/control overhead of IM, compared with streaming oriented voice/video applications. It figures out that shift from connection oriented to connectionless can solve the problem. A new slim Radio Resource Control (RRC) state with corresponding slim signaling transfer procedures is proposed for the connectionless scheme. Numerical results show that great signaling/control saving can be achieved with our new design.
