TelCos approach to services

Abstract

Telcos have been in charge of network access, control, and intelligence for many decades, but the service ‘webification’ has left them unable to compete in the service arena. Now, Operators seeking to transform the service layer, as well as the Voice session control, find that IMS will only help to migrate traditional services. The IMS framework does not offer a web-like application layer, but only a SIP-based interface to application servers. While it is suitable for large Voice systems, the session controller restricts the logic flow, unlike web applications that are free to initiate and integrate other services. Even the combination of IMS and SDP is not agile enough to give operators the competitive edge that they need.
