3. GSM Network
 Network switching subsystem (NSS) (or GSM core network) is the component of a
GSM system that carries out call switching and mobility management functions for
mobile phones roaming on the network of base station.
 The NSS originally consisted of the circuit-switched core network, used for
traditional GSM services such as voice calls, SMS, and circuit switched data calls.
 It give the access to the services such as WAP, MMS, and the Internet.

4. Mobile Switching Center
 The mobile switching center (MSC) is the primary service delivery node for
GSM/CDMA, responsible for routing voice calls and SMS as well as other services
(such as conference calls, FAX and circuit switched data).
 The MSC sets up and releases the end-to-end connection, handles mobility and
hand-over requirements during the call and takes care of charging and real time pre-
paid account monitoring.
 Gateway MSC
 Visited MSC

5. HLR/VLR
•HLR stores user profile of all the users of its area.VLR stores copy of user profile of
users currently residing in its area (LA).
•Location Registration
•Call Delivery
