Abstract

Wireless networks are evolving very fast and user's demands are increasing. A lot of operators already offer first fixed-mobile services. In the future operators will need to enable users to use communications independent from access technologies. In this paper we presented simulation results for handover between WLAN and HSDPA network using SIP protocol. To achieve more credible results we used characteristics of real operator's networks. Simulation results show that characteristics of today's networks are not good enough to offer seamless handover using SIP protocol and that mobile packet wireless networks will need to improve to offer lower latencies.
