Abstract
Abstract In one embodiment, a method comprises measuring a set of parameters for each of the available networks using an application layer protocol (e.g., HTTP). The method further comprises determining an overall quality level for each of the available networks based on the parameters, and choosing the network based on the overall quality level. In some embodiments, the set of parameters are measured by communicating with each of a plurality of predetermined servers within a respective network. Among other advantages, embodiments disclosed herein enable a quantified approach to user experience estimation and application-level Quality of Experience (QoE) measurements, which can serve as bases for selection of radios for the applications.
