Abstract:
4G/5G mobile network plays a vital role in offering ubiquitous Internet access for billions of global users and trillions of IoTs. Despite its importance, its networking research has been largely overlooked. R&D efforts mainly lie above (TCP/App optimization) or below it (advanced wireless and raw system capabilities). In this talk, Dr. Peng will introduce a new perspective to innovate 4G/5G network. We envision that a mobile network should be open and intelligent. To fulfill this vision, we have to overcome three long-standing technical barriers: (1) Mobile networks are largely closed. (2) Their software stack is much more complex than the Internet. (3) Control functions are mandated primarily from the infrastructure side and devices act as a rather passive role despite increasing power.
We break up all three barriers with a new data-driven, device-centric, software-defined approach. First, we have opened up data-driven mobile network analytics by designing and developing MobileInsight and construct protocol analytics and inference at the phone, without assistance from operators. Second, we have empowered learning and reasoning functions with network verification to assert correctness and provable properties by design. Finally, we make full use of device capabilities available but unexplored to open up ample solution space of exploring device-based, rather than infrastructure-centric, approaches to 4G/5G. Dr. Peng will present several interesting showcase studies to demonstrate the benefits and promising potentials of such mobile network intelligence.
