Safeguarding investments when moving to all-IP and IMS.
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 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.
A vital factor influencing the uptake of IMS as the preferred core network for voice and multimedia communications is the extent to which the migration process can safeguard past investments in value-added services. This paper describes an approach and strategy for safeguarding these investments, and how operators can, over time, migrate VAS in the circuit-switched network to IMS.
