In this paper the soft, vertical handover of streamed multimedia in a 4G network is considered. We propose a soft handover solution in which the mobile client controls the handover. This solution requires no modifications to existing wireless networks. The second stream required for the soft handover is duplicated just above the transport layer, rather than requiring the server to play out a second stream that needs to be synchronised with the existing stream. Such a scheme is outlined, and the results are presented that show how the scheme functioned in an emulated environment.
