As operators evolve current network infrastructures - from Signaling System Number 7 (SS7) to IP-based networks, or from CAMEL Application Part (CAP) 1 or 2 to CAP 3 or 4 - they must continue to deliver legacy services to protect key revenue streams. While maintaining legacy functionality and changing signaling protocols, providers must also continue to innovate, developing new, compelling offerings that create strategic competitive advantage. Complicating this effort is the way legacy services are often linked to specific networks, making it difficult to transition to new technologies, leverage existing investments, and deploy services cost-effectively. Adding to the urgency of migration is the approaching end-of-life of many in-house Service Control Point (SCP) platforms and the high cost of maintaining these aging systems.
