One of the latest phenomemn in telecom sector is fixed-mobile convergence.
ABI Research has found that, by 2011, some 250 million users will be making and receiving phone calls over converged fixed-mobile networks and access points, and the firm expects capital expenditure in fixed-mobile convergence infrastructure to exceed $450 million by 2011. That equates to around 10 percent of households and 8 percent of enterprises using some form of fixed-mobile convergence access point on the premises. This will include UMA and SIP-based solutions, both supporting voice call continuity.
There are several competing technologies for fixed-mobile convergence including use of UMA to aggregate traffic from femtocells and Wi-Fi access points in the home, and picocells in the office. In the longer term, IMS-based solutions will be deployed using SIP to offer rich voice sessions over converged devices.
