BPEL Implementation of QoS-Based Management in Multi-Modal Mobile Communications
In this paper, the authors consider the concept of "Partial handover" of connections in multi-modal mobile packet communications. This is based on the idea of a partial transfer not a total one, e.g. 10%-90% of the connection. Maintaining at a minimum level the channel with reduced QoS (Quality of Service), with drastically reduced energy consumption, has also the advantage of keeping a signaling path practically "On common channel". It is also useful to simply restore the preponderance of a channel if its QoS increases significantly, without the complications of restarting the radio link, even if this could be internally triggered, at the mobile terminal level, through the other path which is still active.
