Introduction to 3GPP




The 3rd Generation Partnership Project (3GPP) unites six telecommunications
standards bodies, known as “Organizational Partners” and provides their
members with a stable environment to produce the highly successful Reports
and Specifications that define 3GPP technologies.
These technologies are constantly evolving through - what have become known
as - Generations of commercial cellular / mobile systems. 3GPP was originally
the standards partnership evolving GSM systems towards the 3rd Generation.
However, since the completion of the first LTE and the Evolved Packet Core
specifications, 3GPP has become the focal point for mobile systems beyond
3G.
From 3GPP Release 10 onwards - 3GPP is compliant with the latest ITU-R
requirements for IMT-Advanced ’Systems beyond 3G’. The standard now
allows for operation at peak speeds of 100 Mbit/s for high mobility and 1 Gbit/s
for low mobility communication.

Introduction to 3GPP
Technical Specification Groups
 The TSG Service and System Aspects (TSG-SA) is responsible for the overall
architecture and service capabilities of systems based on 3GPP specifications
and, as such, has a responsibility for cross TSG co-ordination.

TSG Radio Access Network (TSG RAN) is responsible for the definition of the
functions, requirements and interfaces of the UTRA/E-UTRA network in its two
modes, FDD & TDD.

The TSG Core Network and Terminals (TSG CT) is responsible for specifying
terminal interfaces (logical and physical), terminal capabilities (such as
execution environments) and the Core network part of 3GPP systems.

FCC approves LTE standard public safety network

Federal Communications Commission (FCC) annouced that
 "...all 700 MHz public safety mobile broadband networks [are] to use a
common air interface, specifically Long Term Evolution (LTE), to support
roaming and interoperable communications... “

The FCC’s actions today build on the technical requirements that state and
local 700 MHz broadband waiver recipients are already subject to in the early
buildout of their regional public safety broadband networks.

Work in 3GPP: Study for Proximity-based Services

Start of work in 3GPP
 Work Item: Study for Proximity-based Services (3GPP TR 22.803)

Objective (SA-Plenary doc SP-110638):
 to study use cases and identify potential requirements for an operator
network controlled discovery and communications between devices that are
in proximity, under continuous network control, and are under a 3GPP
network coverage, for:
 Commercial/social use
 Network offloading
 Public Safety
 Integration of current infrastructure services, to assure the consistency
of the user experience including reachability and mobility aspects

Work in 3GPP: Study for Proximity-based Services

Objective (SA-Plenary doc SP-110638):
 Additionally, the study item will study use cases and identify potential
requirements for
 Public Safety, in case of absence of EUTRAN (LTE) coverage
(subject to regional regulation and operator policy, and limited to
specific public-safety designated frequency bands and terminals)
 Use cases and service requirements will be studied including network
operator control, authentication, authorization, accounting and regulatory
aspects.
 The study does not apply to GERAN or UTRAN
 Important: LTE only!

Work in 3GPP: Study for Proximity-based Services
Current Status of TR 22.803 for Release 12:
 Start of study in TSG SA for work on requirements
 First Public Safety Use Cases are included:
 Basic ProSe one to one direct user traffic initiation in public safety
spectrum dedicated to ProSe services
 UE with multiple one to one direct user traffic sessions in public safety
spectrum dedicated to ProSe services
 ProSe Discovery Within Network Coverage
 ProSe Discovery Out of Network Coverage
 Can Discover But Not Discoverable
 More Use Cases to be done in future meetings
 Use Cases build on requirements given by FCC/NIST
 Commercial Use Cases still under discussion
 Future works in TSGs RAN and CT after finishing study in TSG SA

Work in 3GPP: Work Item on group communication


Introduction of group communication features to LTE
 New Work Item: Group Communication System Enablers for LTE (SAPlenary doc SP-120302 for approval by SA#56 Ljubljana, 18-20 June 2012)
 TR number will be availble after approval
Justification:
 Group communication is a key functionality of LMR/PMR and public safety
systems. Such functionality exists for voice calls in existing systems such as
Tetra, P25 and GSM-R. In the latter, this functionality was specified by
SMG/3GPP as Voice Group Call Service (VGCS-TS42.068). Such
functionality consists of a group delivery of calls to users as well as
considerations about set up and management of groups.
 To position LTE as technology for public safety communication, group
communication will be needed. Group communication function will
complement its sibling communication feature of proximity-based services
(ProSe).

Work in 3GPP: Work Item on group communication

Objective :
 This WI shall specify the system enablers to the 3GPP system to support
group communication over LTE for Public Safety.
 The communication will consist of various media. Examples of media
consist of conversational type communication (voice, video) or streaming
(video) or data (messaging) or a combination of them
 From a public safety perspective, the US requirements as specified in
NPSTC (Mission Critical Voice Requirements) would be considered as
starting point.
 Other regional requirements may also be reflected in the work. The
requirements shall be worded in a way to easily accommodate future
requirements from other regions or stakeholders.

Work in 3GPP: Work Item on group communication

Objective continued:
 At least requirements on the following topics shall be provided:
 Group Communication
 Group size
 Group Handling
 Priority Handling
 Call establishment times
 Resource efficiency
 GCSEL shall not define requirements for ProSe. All ProSe groups
communications will be defined within ProSe.
 Management of group communications will be defined in GCSEL
 GCSEL should aim at re-using existing, standardized functionality when
possible and justified
 A gap analysis of existing specifications will be done and is foreseen to be
included as an informative annex to the TS.
