Application Layer
The “Application Layer” is responsible for providing services to users via
applications regardless of the device and method in which the useraccesses the network. The Application Layer itself is not a real network as
such important operator parts of the application Layer may, however, be
realized in what are called Service Networks.
Control Layer
The “Control Layer” contains nodes that control and direct traffic (bothCircuit and Packet Switched). The Control Layer is realized in a Core
Network. The WCDMA Core Network will contain, for example, MSCs,
HLR/HSS, GMSC/TSC, SGW and possibly IMSI(IP Multimedia Sub system)

Connectivity Layer
The “connectivity Layer” consists of the transport nodes (M-MGW,
SGSN and GGSN) and connects to the various access networks.
The Access Network consists of the base stations and controllers in the
mobile networks(GSM, UMTS, CDMA) or fixed access, transport and
connectivity network that are able to handle different types of traffic (e.g.
Circuit Switched and Packet Switched data). For WCDMA, the Access
Network is realized as the WCDMA Radio Access Network.

WCDMA is standardized by the Third Generation Partnership Project (3GPP).
Based on the 3GPP reference network model, the WCDMA network can be
considered to consist of four major components:
• User Equipment (UE)
• Access Network (AN)
• Core Network (CN)
• Network External to WCDMA

Advantages of Mobile Soft switch Solution
1. Packet backbone technology (IP or ATM) enables more efficient transmission of voice traffic over the backbone by retaining the same voice coding in the backbone as is used in the air interface
2. Access independent (GSM/WCDMA) core network
3. Reduction of backbone traffic
4. Simplification of network planning through common core for WCDMA & GSM

MSC (GSM)
The MSC (GSM) handles Control Layer functions related to circuit-mode
communication services within a Classical within a Classical MSC
Architecture based network for example, mobility management and
connection management services.
Gateway MSC Server (GMSC Server)
The main function of GMSC server is for routing calls to mobile subscribers
by obtaining routing information from the subscribers HLR.

Home Location Register (HLR)
Home Location Register (HLR) serves as the primary database of
subscriber information used to provide control and intelligence within the
GSM/GPRS and WCDMA networks.
The HLR manages mobile subscribes profiles as well as subscriber location
and activity, and also handles supplementary services.

Authentication Centre (AUC)
The Authentication Centre (AUC) contains functions for secure storage of
individual subscriber identifiers and keys. AUC also includes algorithms necessary
for generating authentication and ciphering data based on the subscriber keys. The
authentication and ciphering data, provided by the AUC upon request, are used by
different network elements to protect the network, users and operators against
unauthorized use of the system.
Equipment Identity Register (EIR)
The EIR database validates mobile equipment hardware identity, The MSC can
request the EIR to check if an MS has been stolen or is faulty (black listed), not
type-approved (gray listed), normal registered (white listed), or unknown.

Flexible Number Register (FNR)
The FNR node offers:
•Mobile Number Portability (MNP): This feature permits an end-user
to keep his MSISDN identity when changing service provider or
moving subscription between two service domains within the same
country.
•Flexible Allocation of MSISDN for the GSM and WCDMA networks.
This feature provides mobile operators with free allocation of
subscription identity without considering the relation between
MSISDN and IMSI series in the HLR.
