The document discusses trends driving fixed and mobile operators toward convergence. It outlines key drivers like declining voice revenues, increasing data traffic, and customer demand for single services across fixed and mobile networks. It then summarizes various pre-IMS technological solutions operators can use to begin providing fixed-mobile convergence, like UMA, SIP-based solutions, and integrating with IP-PBX systems.
