Objectives

After completing this module, the student should be able to:

Mention connectivity of Network Elements in Release 4List the main functions of the MSS, MSSu, GCS and CDS

Explain the main functions of each functional unit

List the redundancy principles for the units in MSS, MSSu,

GCS and CDSExplain the main difference between the standalone MSS

and integrated MSS

MSS, MSSu & GCS

MSS

Standalone MSS: New delivery from M12 onwards Integrated MSS : Same as current MSCi

MSSu

Upgraded from the operators current MSCi, removing units handling

user plane.GCS

A compact standalone Gateway Control Server , does not have BSU &

VLRU (Transit switch functionality).

CDS

New delivery from M12 onwards. Used for circuit switched data calls

along with standalone MSS.
