Mobile communication | 3G| 4G/LTE | 5G

MS: Mobile station (mobile)
BS: Base station(tower)
BSC : Base station controller( tower controller, traffic management, tower down up management)
MSC: Mobile Switching centre(manages multiple BSC
has helpers like
HLR:
Home location Resister.
1. maintains each sim info, address
2. your pre paid post paid, data and balance info, sends msg of renewal
RLR:
Remote location register
NSS: Network switching Station


Terminologies



3GPP
 3rd Generation Partnership Project (3GPP) 

 is a collaboration between groups of telecommunications standards associations
SAE
System Architecture Evolution

 core network architecture of 3GPP's LTE wireless communication standard
LTE
Long-Term Evolution

is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies
GSM



EDGE

UMTS
 Universal Mobile Telecommunications Service (3G)
is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps). UMTS offers a consistent set of services to mobile computer and phone users, no matter where they are located in the world. UMTS is based on the Global System for Mobile (GSM) communication standard.

HPSA

MME
Mobile Mobility Management
RAN
Radio access Network
GeRAN

E-UTRAN
Evolve UMTS Terrestrial Radio Access Network
MCM
(Master Controller Management)
MSM

RNC (Radio network controller in 3G)






LTE (Long term evolution) 4G

RAN of LTE = Evolved UMTS Terrestrial Radio Access Network(e-UTRAN)


LTE/4G Base station

LTE Base station =  RNC function + NodeB or BTS + BCS

 RAN Elements  Antennas  convert electrical signals into radio waves. Radios  transform digital information into signals that can be sent wirelessly and ensure that transmissions are in the correct frequency bands with the right power levels. Baseband units ( BBUs )  provide a set of signal processing functions that make wireless communication possible. Traditional baseband uses custom electronics combined with multiple lines of code to enable wireless communication, typically using the licensed radio spectrum. BBU processing detects errors, secures the wireless signal and ensures that wireless resources are used effectively. RAN Radio Resources  Radio Resources Management Techniques  Power control, scheduling, cell search, cell reselection, handover, radio link or connection monitoring, and connection establishment and re-establishment. bearer selection (Master Cell Group (MCG),  bearer, Secondary Cell Group (SCG) bearer, Split bearer),       Major factors for RAN capabilities Channel
