The growth in wireless data traffic is driving Communication Service Providers to evolve towards deploying 4G access technologies such as LTE, this in-turn is increasing the demand for quickly delivering new and innovative services to the end subscribers. Service Providers need to develop compelling applications with carrier-grade reliability and performance to attract and retain new subscribers with a short time-to-market. OCCAS 5.1 introduces built-in communications support for services such as VoLTE and RCS, provides foundation for building virtualized services and has many other key capabilities that are required for the operators to deploy media-rich communication services quickly and with a reduced cost of deployment. Oracle Communications Converged Application Server 5.1 was released in December 2012. Please see the press release here
