Its all started from these… (early days of
telecommunications)
● Sound can travel over media (thread / wire)
● Sound can travel through electricity
● Speaker and microphone were invented
● Mesh connection? Not an option

Telecommunication system
● A hub is created that connects all CPEs → CO
● Switching functions are automated (digital switch)
● We need to separate signalling and data (voice) →
off-band signalling, CCS, version 7 → CCS7 → SS7
● Benefits:
○ Utilize voice link (money)
○ Can create more services (money):
■ Hunting
■ SMS
■ Toll-free
■ Service number
■ Etc. you name it

SS7 architecture
components:
● Service Control Points/SCP.
integrated databases and
computers
● MTP (Message Transfer Part).
which refers to data circuit
● STP (Signal Transfer Points).
Similar to switch
● ISUP (ISDN User Part)

Mobile communication (2G)
● 1990s
● TDMA (time division multiple
access)
● Frequency reuse
● Digital signal (MS to tower)
● Encryption of digital signal
● Nodes:
○ BTS
○ BSC
○ MSC
○ HLR
○ VLR

Mobile communication (2.5 G)
Additional improvement
● New modulation → higher speed
● Ability to connect to datanetwork (packet switch) -> GPRS
● GPRS (general Packet Radio Service)
○ SGSN (serving GPRS support node)
○ GGSN (gateway GPRS support node)

Mobile communication (4G)
● New packet switch core (EPC - evolved packet core, LTE - Long term
evolution)
● Want to get rid of legacy tech (Circuit Switch - CS)
