016 - GSM Technology - GPRS Objective: - Understand GSM Technology - GPRS & EDGE By the end of this session, participants will be able to: Today Our key issue is:

016 ,[object Object],[object Object],[object Object],[object Object],[object Object]

016 GSM Frequencies ,[object Object],[object Object],[object Object],Higher the frequency GSM network is working on, better the overall service level

016 ,[object Object],[object Object],[object Object],[object Object],[object Object],The GSM network can be divided into four main parts:

016 AUC VLR HLR MSC EIR OSS ISDN PSTN PLMN PSDN BSC BTS MS SIM BTS BTS Architecture of GSM Network NSS BSS

016 Mobile Station (MS) A Mobile Station consists of two main elements: (a) The Subscriber Identity Module (SIM) (b) Mobile equipment/terminal (ME)

016 - Interface between the MS and the NSS - In charge of the transmission and reception It can be divided into two parts: (a) Base Station Controller (BSC) (b) Base Transceiver Station (BTS) or Base Station Base Station Subsystem (BSS)

016 Base Station Subsystem (BSS) (a) Base Station Controller (BSC): (b) Base Transceiver Station (BTS) or Base Station: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

016 Network and Switching Subsystem (NSS) ,[object Object],[object Object],[object Object],Main Role:

016 Network and Switching Subsystem (NSS) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],(b) Gateway MSC (GMSC): - A gateway that interconnects the cellular network and the PSTN. - In charge of routing calls from the fixed network towards a GSM user. (a) Mobile Switching Center (MSC):

016 ,[object Object],[object Object],[object Object],Network and Switching Subsystem (NSS) (c) Home Location Register (HLR): (d) Visitor Location Register (VLR): ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

016 - Provides an interface to various networks for data communications. ,[object Object],[object Object],(e) Authentication Center (AUC): Network and Switching Subsystem (NSS) ,[object Object],[object Object],[object Object],(f) Equipment Identity Register (EIR): (g) GSM Internetworking Unit (GIWU):

016 - OSS is connected to components of the NSS and the BSC to control and monitor the GSM system. - OSS is In charge of controlling the traffic load of the BSS. Operation and Support Subsystem (OSS)

016 GPRS (General Packet Radio Service) - Speed: Up to 115 kilobits per second - It is a standard for wireless communications GPRS Basics - Compared with current GSM systems' 9.6 kilobits. - GPRS supports a wide range of bandwidths - Particularly suited for sending and receiving small bursts of data, such as e-mail and Web browsing, as well as large volumes of data.

016 GPRS (General Packet Radio Service) The GPRS Capability Classes Class A ,[object Object],[object Object],[object Object]

016 GPRS (General Packet Radio Service) The GPRS Capability Classes Class B ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

016 GPRS (General Packet Radio Service) The GPRS Capability Classes Class C ,[object Object],[object Object],[object Object]

016 GPRS (General Packet Radio Service) GPRS Multislot Classes are: Class 2 Minimal GPRS implementation Class 4 Modest GPRS implementation, 50% faster download than Class 2 Class 6 Modest implementation, but with better uploading than Class 4 Class 8 Better implementation, 33% faster download than Classes 4 & 6 Class 10 Better implementation, and with better uploading than Class 8, seen in better cell phones and PC Cards Class 12 Best implementation, with maximum upload performance, typically seen only in high-end PC Cards
