Perceived Quality Driven Multimedia QoS Optimization

Arrangement for optimizing the perceived quality of service (QoS) relative to a multi-mode mobile terminal device (102) and associated multimedia application running over a packet network, such as audio and/or video streaming application, comprising a network QoS measurer configured to obtain, relative to a plurality of wireless communications networks of different technology capable of supporting packet data transfer for serving the multimedia application, a number of QoS metrics indicative of the network performance of each network, a perceived QoS estimator configured to estimate the current perceived QoS for each network on the basis of the associated QoS metrics obtained indicative of the network performance and said multimedia application, and to suggest whether to stay with the current network or switch into another network providing a higher level of perceived QoS for the multimedia application associated with the multi-mode mobile terminal according to the performed estimation, and a mobility handler for initiating a vertical handover in response to such suggestion by the perceived QoS estimator. A corresponding method is presented.
