IMS and Service Configuration Management (SCM)

  • Service Configuration Management reduces cost.
  • Service Configuration Management (SCM) is a missing piece in the IMS model. The tools that allow the carrier, or the customer, to alter or revise their service parameters have not been included in the IMS definitions. Although in most cases, service providers tend to keep full service creation tools proprietary and not open to customers, there are increasing amounts of self-provisioning or self-selection of features over which customers can exhibit greater control.
  • Service Configuration Management functions dive deeper into the Control Plane to affect the HSS and, therefore, will engender a much greater scrutiny by the carrier. Although they offer greater control for customers and help reduce administrative costs for carriers, the potential for abuse of such access into the HSS must be managed. Some service providers may retain full control over all service configurations in order to limit third-party access into the HSS systems.
  • One important consideration is how to set the boundary between the elements that the customer can control, that the third-party application developer can control and where the carrier reserves control to themselves. Control over service authorization and billing-impacting transactions are not likely to transfer into customer hands or developer hands too quickly. The potential for abuse and unauthorized access will limit the openness of freely passing this sort of transaction. More minor functions to set optional parameters and features offer the opportunity for the customer to set their preferences with no action on the part of the service provider.
