Abstract
Techniques are disclosed for evaluating an ongoing VoIP call over a combination of IP data communication network connections for purposes of determining when to hand it off to a circuit-switched cellular network connection. Multiple IP stream call quality values X1(i), X2(i), and Xb(i) are sampled over a time period (N) of (j) samples for an ongoing telephone call and stored. Instantaneous annoyance values a1(j), a2(j), and ab(j) for each of the stored call quality values for each of the IP streams within sampled time period (N) are calculated. Current accumulated annoyance values A1(i), A2(i), and Ab(i) are obtained by summing the instantaneous annoyance values a(j) for each IP network. The combined IP stream accumulated annoyance values Ab(i) is compared to a handoff threshold values Hb(i). A handoff of the telephone call a circuit-switched cellular communication link is initiated when the accumulated annoyance value Ab(i) is greater than the handoff threshold value Hb(i).
