Next-Generation Intelligent Networks: Migrating To IMS
Safeguarding investments in value-added services when moving from circuit-switched networks to all-IP and IMS. How operators can integrate existing value-added services in the evolving IMS network. Many telecommunication operators find themselves in a transition phase. They will migrate Circuit-Switched (CS) networks to the IP Multimedia Subsystem (IMS), a process that could span several years. Many of these operators have also invested large sums in developing (either in-house or in collaboration with third parties) and deploying Value-Added Services (VAS) in circuit-switched networks.
