2. Architecture of GSM & GPRS

3. Component
 MS (Mobile Station)
 BTS (Base Transceiver system)
 BSC (Base Station Controller)
 MSC (Mobile Station Center )
 PSTN (Public Switch Telephony Network)
 SS7
 HLR (Home Location Register)
 GPRS (General Packet Radio service)

4. MS (Mobile Station)
 Hand portable Unit
 Contain mobile equipment (ME)
 Subscriber Identity Module (SIM)

5. BTS (Base Transceiver system)
 Handles the radio interface to the mobile station
 Consists of one or more radio terminals for transmission and reception
 Each radio terminal represents an RF channel
 Received data transcoding
 Voice encryption and decryption.

6. BSC (Base Station Controller)
 Provide all the connection and physical links between MSC and BTS
 Monitor and control several BTS
 Management of channel on the radio interface
 Alarm handling from the external interface
 Perform inter-cell handover
 External interface-
- ‘Abis’ interface towards the BTS
- ‘A’ interface towards the MSC

7. MSC (Mobile Station Center )
 Perform all switching
 Interfaces to all cellular network to PSTN
 Paging
 Billing

8. GPRS (General Packet Radio service)
 GPRS (General Packet Radio service) is a new bearer service of GSM that
greatly improves and simplifies wireless access to packet data network
 GPRS applies packet radio principle to transfer user data packet in an efficient
way b/w MS & external packet data network.

9. PSTN (Public Switch Telephony Network)
 PSTN (Public Switch Telephony Network) is basically the inter-connected
telephony system over which telephone calls are made via copper wire.
 PSTN based on the principle of circuit switching
 Telephony calls transmitted as analogue signal across the copper wire
