Study Notes
SSF (Service Switching Function)
- Represents the switching functions of the IN network
- Detects IN service invocations (ISTs) and interrogates the appropriate SCF for instructions on how to handle the call
- Can be located within the (G)MSC Server, in which case it is not a separate physical node in the network
- Can also be located in a separate transit exchange (without mobile functionality), in which case it is called a (stand-alone) SSP and can be seen as a separate node in the network
gsmSSF (GSM Service Switching Function)
- Represents the switching functions of the CAMEL Service Environment (CSE)
- Detects CAMEL calls and interrogates the appropriate gsmSCF for instructions on how to handle the call
- Located within the (G)MSC Server and cannot be a separate physical node in the network

Description
Learn about the roles of SSF and gsmSSF in telecommunications networks, including how they handle IN service invocations and interact with the SCF. Understand the difference between SSF within the (G)MSC Server and a stand-alone SSP.
