Function of MSC Server and MGWFunction of MSC Server and MGW

MGW is responsible for media resource processing , codec conversion of

speech ,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 operator’s requirement

Bearer Type of MGWBearer Type of MGW

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

By adopting independent cards to provide TDM/ATM/IP interface , MGW can be flexibly configured according to operator’s option and networking requirements

The traffic interface include:

E1, ET-155 for TDM interface,

STM-1 for ATM interface

FE, GE for IP interface

Multiple Signaling BearerMultiple Signaling Bearer

The MSC server can provide both TDM based signaling interface and IP based

signaling interface

The MSC server can also provide TDM based signaling interface via independent

SG

The signaling interface include:

E1(64kps digital link), or unstructured E1 for TDM interface

FE for IP interface
