N2 - The evolution of unlicensed wireless technologies such as WiFi or WiMAX have influenced next generation networks to adopt them as extensions of cellular networks. Nowadays, it is not surprising to see heterogeneous wireless networks coexisting on a daily basis i.e. UMTS, WiFi, and WiMAX. Unfortunately, some technical issues and the lack of roaming agreements between network operators prevent interoperability. One of the goals of the so-called wireless convergence is to enable service mobility between heterogeneous wireless networks. In this context, we propose in this article a SIP-based Roaming Signaling protocol for heterogeneous multi-operator wireless networks. Our objective is to provide QoS-aware heterogeneous roaming in multi-operator environments with minimal changes in current wireless architectures.
