Architecture composing

separate MSC Server and

MGW with virtual MGW

concept provides

possibility to improve

resilience against physical

MGW failures as

RNC/BSC can be

connected to more than

one MGW

A (TDM based) interface

is always dedicated tosome virtual MGW while

Iu is not (ATM based).

Control plane relationship

is between BSC/RNC and

a single MSS

One physical MGW can be

divided up to 50 virtual

MGW. MSS can control up

to 100 (virtual) MGWs.

Reconfiguration includesconfiguration of BSCs/
