CHAPTER 2, Base Station Subsystem (BSS) - Coggle Diagram
CHAPTER 2
-
(Fifth generation) 5G
Peak data rate:Downlink: 20 Gbps, Uplink: 10 Gbps
Mobile technology designed to meet the requirements of IMT-2020 set by the ITU-R specification M.2083.
Faster download/Faster upload speeds and low latency, compare to 4G.
Offering acceptable levels of energy consumption, equipment cost and network deployment and operation cost.

Network Subsystem (NSS)
MSC
- Controller for all base stations in service area
- Provides link other MSC and to other networks such as PSTN
HLR
- store and maintain information subscriber's identity (profile), the home of MSC and servicers purchased.
- information is placed in the HLR by the provider when sign up for service.
VLR
- Database that keeps track all visiting subscribers when they roaming in an area that served by non-home MSC.
- Receives information from the a subscriber’s HLR

Global System for Mobile (GSM) System Architecture
Mobile Station
-
SIM is a memory to store the IMSI, encryption keys, entitled services and specific information used to identify and authenticate subscribers (ME) on the network.
International Mobile Subscriber Identity (IMSI) is used to identify the user of a cellular networks and is a unique identification associated with all cellular networks
Gateway MSC
Link the GSM network to other network; such as PSTN, ISDN and PDN.
GPRS System
SGSN: forms a gateway to the services within the network.
GGSN: forms the gateway to the outside world.
PCU: Packet Control Unit, PCU, which differentiates whether data is to be routed to the packet-switched or circuit switched networks
