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

Bearer Type of MGW

MGW provides TDM/ATM/IP interface for bearer network transporting 3GCS traffic

By adopting independent cards to provide TDM/ATM/IP interface , MGW

can be flexibly configured according to operators option and

networking requirements

The traffic interface include:

E1, ET-155 for TDM interface,

STM-1 for ATM interface

FE, GE for IP interface

Confidential Information of Huawei.No Spreading without Permission. Security Level: Internal

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

secret.

The TMSI consists of 4 bytes( 8 HEX numbers)

and determined by the telecom operator.

MSRN/HON

The MSRN is used to route the call to the MSC which MSis currently located.

The HON is used by the MSC-A to set up a connection to

the MSC-B during handover process

Usually, MSRN and HON share the same numbering plan.

The format is CC+NDC+individual number. CC and NDCis the same as that of MSISDN. The individual number is

taken from a pool of numbers specially reserved for

MSRN.

MSRN: Mobile Subscriber Roaming Number

HON: Hand-over Number
