The multiple registration scheme can reduce signaling overhead at the expense of increased session setup latency in cellular-WLAN integrated systems. In this paper, we propose a timer-based session setup procedure, which can reduce the session setup latency by looking for a user based on the estimation of the WLAN residence time. We investigate the optimization of the timer under realistic WLAN residence time model. Numerical results demonstrate that the timer-based session setup procedure can reduce the session setup latency by means of adaptive timer setting.
