BellSouth is completing the circle of next generation of network architectures between its co-owned wireless carrier Cingular and SBC Communications, announcing today it has selected Lucent Technologies IP Multimedia Subsystem platform as the launch point for VoIP and possible future converged services.
BellSouth’s widely expected decision to go with Lucent will give the RBOC along with SBC and Cingular the same control plane architecture, allowing easy cross-integration between Cingular’s cellular network and the two RBOCs own extensive array of wireline assets. Despite those convergence possibilities, BellSouth is starting with a narrower focus, using the IMS architecture to launch advanced VoIP services over its FastAccess DSL footprint.
Lucent will deploy its Lucent Network Controller, the call session control function (CSCF) element that directs every transaction over the network using SIP, and Lucent’s media gateways bridging the access and next-generation core networks.
The deal also clearly positions Lucent as the definitive leader in IMS in the U.S. and a major player globally. Lucent has one a major piece of each of the four IMS implementations announced so far in the U.S., supplying the critical call session control function element to each.
