Abstract
Users’ preference of WLAN-access has potential effect on the performance of a UMTS cell with underlying WLANs. In the models with complementary-WLANs, the hybrid users (i.e., UMTS users having WLAN privileges) are permitted to access WLAN only in the event of blocking of their data-requests in UMTS. So, a user sometimes misses the high speed data services of WLAN because he/she does not access WLAN as long as UMTS bandwidth is available. Though, this model decreases the dropping probability of a UMTS request (i.e., call), the complementary benefit, at high traffic load, decreases. We develop an analytical model with tunnel-WLANs in which a hybrid user always accesses the WLAN as soon as he/she enters a WLAN hotspot. The numerical results show that the dropping probabilities of requests in the models with complementary-WLANs and with tunnel-WLANs are almost same at low traffic environment. But, at higher traffic load, the dropping probability of a request in a model with tunnel-WLANs is better than that in a model with complementary-WLANs.
