Everyone enjoys the smartphone revolution - users, developers, network operators, device vendors and network equipment vendors such as Ericsson. However, there are challenges since the network systems have not been optimised for smartphones from start. Until recently, the key optimisation objectives for mobile broadband networks have been peakrate and throughput, which are still important properties. The advent of mass-usage of smartphones, and the related traffic, has shown that also other properties of the 3G radio and networks are important. In particular, the high frequency of data activities, sometimes with moderate volumes of data transferred, has lead to both a high battery drain, and increased the signaling load in the system, due to the transitions between the standardised states of the 3G radio.
