Host-based distributed mobility management: Example of traffic offloading

Recent technical breakthroughs in wireless communications have facilitated significantly increased data rates and reduced end-to-end latency in cellular networks. Higher throughputs however lead to increase traffic loads on cellular networks and require mechanisms to mitigate such traffic loads on the cellular networks. In this paper, we introduce a host-based distributed mobility management protocol supporting selective traffic offloading for the evolution of the 3GPP core network architecture. Unlike the current approach of 3GPP, traffic offloading is achieved based on IP flow mobility in a distributed manner. The offloading point is thus also distributed. We show how the proposed host-based distributed mobility management protocol alleviates the high traffic loads in the evolution of the 3GPP core network architecture.
