14. 14 Challenges in Mobile Internet the mobility in heterogeneous Network with the services continuity –Scenarios: LTE / WiFi /WiMAX? –3GPP choose Loose couple between 3GPP Network and Non-3GPP network. However, It would be difficult to keep the services continuity. –IEEE 802.21 try to define a mechanism for handover in heterogeneous network. However, it is hard to be accepted by 3GPP. User capacity and Always on Looking for new business model for the convergence of Mobile network and Internet
