Call Session Control Function
The Ericsson Call Session Control Function (CSCF) is a central component of the IP Multimedia Subsystem (IMS), managing all signaling from the end user to services and other networks. CSCF can control fixed and mobile IMSs in converged networks containing functional modules required to manage signaling from end user, allocating application servers, establishing emergency connections, and controlling communication with other networks.
CSCF can be deployed in multiple cloud environments, such as OpenStack, VMware, and the Ericsson NFVI. It is also verified on the Ericsson software-defined infrastructure (SDI) and can be delivered as a part of industrialized solutions.
OUR KEY BENEFITS
In commercial operation since 2005, Ericsson CSCF is the world’s most widely deployed and reliable CSCF (providing higher than 99.999 percent availability). It features the most field-tested interoperability with standard and non-standard interfaces, terminals, and legacy networks.
The Ericsson CSCF is known about its feature richness, including e.g. support for different security authentication procedures, several high availability and robustness features, and flexible charging mechanisms.
Flexible deployment alternatives
Ericsson CSCF provides flexible deployment alternatives, making it possible to start with a small system and increase capacity as traffic in the solution increases.
