Funct ion of MSC Server and MGW
MGW is responsible for media resource processing , codec conversion ofspeech ,and switching between bearer channel of different type (IP/ATM/TDM)
MSC Server is charge of signaling control, call and service processing, and
resource management etc.
MSC Server and one or more MGW are connected through standard H.248 protocol.
MSC Server and MGW can be geographically distributed as operators requirement

The TMSI is assigned only after successful
subscriber authentication. The VLR controls the allocation of new TMSI
numbers and notifies them to the HLR.
TMSI is used to ensure that the identity of the
mobile subscriber on the air interface is kept
