RELIANCE JIO INFOCOMM LIMITED

• Reliance Jio Infocomm Limited, is an LTE based mobile network operator in India.

• It is a wholly owned subsidiary of Reliance Industries headquartered in Mumbai, that provides wireless 4G LTE service network (without 2G/3G based services)

• It is the only 100% VOLTE operator in the country, with coverage across all 22 telecom circles in India.

Introduction

• RJIL holds spectrum in 1800 MHz (across 14 circles) and 2300 MHz (across 22 circles) capable of offering fourth generation (4G) wireless services.

• RJIL aims to provide anytime, anywhere access to innovative and empowering digital content, applications and services, thereby propelling India into global leadership in digital economy.

Jio Digital Life

• Currently we have following mobile and internet communication technologies adopted by different mobile companies in different parts of the world.

• GSM• CDMA• EDGE• GPRS• VoIP

Mobile Internet Communication Technologies

• 2nd Generation Internet is the most prevalent in India in the Past Decade. Wireless ISPs in India use both CDMA and Edge technologies for 2G.

• India's wireless Internet frequencies are• 2G: GSM 900 MHz, GSM 1800 MHz• 3G: UMTS 2100 MHz• 4G: TDLTE 2300 MHz, FDLTE 1800 MHz

Wireless Internet

Evolution Of Mobile Communication

• High Bandwidth Requirement• Expensive fees for 3G Licenses Services• It was challenge to build the infrastructure

for 3G• Expensive 3G Phones.• Large Cell Phones

WHY 4G ?

• LTE stands for Long Term Evolution • It is a 4G wireless broadband technology

developed by the Third Generation Partnership Project (3GPP), an industry trade group.

• It isn’t as much a technology as it is the path followed to achieve 4G speeds

4G Technology LTE

LTE Architecture

• The high-level network architecture of LTE is comprised of following three main components:

• The User Equipment (UE).• The Evolved UMTS Terrestrial Radio

Access Network (E-UTRAN).• The Evolved Packet Core (EPC).

Components Of LTE Architecture

• The internal architecture of the user equipment for LTE is identical to the one used by UMTS and GSM which is actually a Mobile Equipment (ME).

The User Equipment (UE)

• It is the hardware that is connected to the mobile phone network that communicates directly wirelessly with mobile handsets (UEs), like a Base Tranceiver Station (BTS) in GSM networks.

E- Node B

• The MME (for Mobility Management Entity) deals with the control plane.

• It handles the signalling related to mobility and security for E-UTRAN access.

• The MME is responsible for the tracking and the paging of UE in idle-mode.

• Controls the high-level operation of the mobile by means of signalling messages and Home Subscriber Server (HSS).

MME (Mobile Management Entity)

• Serving gateway terminates the interface towards EUTRAN.

• It acts a mobility anchor for inter 3GPP mobility.

• SGW is responsible for • packet routing and forwarding,• buffering the downlink packets• downlink packet marking.

Serving Gateway (SGW):

• PGW terminates SGi interface towards the PDN.

• PGW is responsible for all the IP packet based operations such as

• deep packet inspection, • UE IP address allocation, • Transport level packet marking in

uplink and downlink, • accounting etc.

PDN Gateway (PGW):

• The HSS is a central database that contains user-related and subscription-related information.

• The functions of the HSS include functionalities such as mobility management, call and session establishment support, user authentication and access authorization.

• It also holds information about the PDNs to which the user can connect.

• In addition the HSS holds dynamic information such as the identity of the MME to which the user is currently attached or registered.

Home Subscriber Server (HSS):

Advantages Of LTE

• Voice over LTE (VoLTE) which is based on the IP Multimedia Subsystem (IMS) network

• This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer.

• This means that there is no dependency on the circuit switched voice network to be maintained.

• VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM.

• Furthermore, it frees up bandwidth because VoLTE’s packets headers are smaller than those of un-optimized VoIP/LTE
