Foreword
rd
This Technical Report has been produced by the 3 Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
Introduction
At a time when the first release of the 3GPP 3G standard has stabilised, and the first 3GPP compliant networks are
going live, the ITU is already working towards elaborating a framework for the future development of IMT-2000 and
systems beyond IMT-2000. In addition, a number of research initiatives worldwide are investigating technologies and
techniques that might fall within that framework. It is therefore timely, that 3GPP look at how its systems will evolve in
the future to meet the requirements of the user and the industry, and to make use of emerging technologies.

1 Scope
The present document describes a long term, high level roadmap, intended to guide the future work of 3GPP. It is
focussed on items pertinent to the evolution of 3GPP specifications, and identifies concepts and trends to be considered
by 3GPP when defining future work items. It does not contain details of proposed technologies, rather it contains
pointers to direct the activities of the appropriate TSGs in elaborating future releases of the 3GPP standard. As a result,
not all of the topics covered herein are within the remit of 3GPP to discuss, and description of such items will not be
extensively developed. E.g. Spectrum is an ITU-R/WRC issue and therefore outside the scope of 3GPP. The document
is designed to be a "living document" and will be updated accordingly over its lifetime in order to reflect future
developments and innovations.

4 The current scope of 3GPP and its Releases
4.1 3GPP Releases
rd
The current scope of 3 Generation Partnership Project (3GPP) is to produce globally applicable Technical
Specifications (TSs) and Technical Reports (TRs) for:
rd
- a 3 Generation Mobile System based on evolved GSM core networks and the radio access technologies that
they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time
Duplex (TDD) modes); and
- the Global System for Mobile communication (GSM) including evolved radio access technologies (e.g. General
Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE)).
In addition, 3GPP shall consider the long term evolution of its systems.
rd
The 3 Generation Mobile System and the Global System for Mobile communication (GSM) and their capabilities are
developed in a phased approach. In the following the content of the 3GPP Releases is briefly outlined.

4.1.1 3GPP Release 1999
3GPP Release 1999 is the first release from 3GPP and covers specifications for a complete mobile system. 3GPP
Release 1999 contains, but is not limited to, UTRA FDD and 3.84 Mcps TDD modes, UTRAN Iu, Iub and Iur
interfaces, GSM based evolved core network, USIM, AMR speech codec, Multimedia Messaging Service (MMS),
Location Services (LCS), a broad range of supplementary services, Customized Applications for Mobile network
Enhanced Logic (CAMEL); Open Service Access (OSA) and telecommunication management.
The 3GPP Release 1999 was functionally frozen in December 1999.
4.1.2 3GPP Release 4
3GPP Release 4 is a further enhancement of 3GPP Release 1999.
3GPP Release 4 contains, but is not limited to, UTRA FDD repeater function, low chip rate TDD option, 700 MHz
support for GERAN, e2e transparent packet streaming service, Tandem Free Operation, Transcoder Free Operation, IP
transport of CN protocols, bearer independent CS core network, CAMEL enhancements and OSA enhancements.
The 3GPP Release 4 was functionally frozen in March 2001.
4.1.3 3GPP Release 5
3GPP Release 5 is a further enhancement of the previous releases.
3GPP Release 5 contains, but is not limited to, the initial phase of the IP Multimedia Subsystem (IMS), High Speed
Downlink Packet Access (HSDPA), UMTS in 1800/1900 MHz bands (release independent), Wideband AMR, IP
transport in the UTRAN, Iu for GERAN, Gb over IP, CAMEL enhancements, OSA enhancement, Global Text
Telephony (this is a Release independent Feature, not a Rel-5 Feature), Location Services enhancements, UTRAN
sharing in connected mode and security enhancements.
The 3GPP Release 5 was functionally frozen in March 2002 and the remaining part in June 2002.
4.1.4 3GPP Releases 6
Work is currently ongoing for 3GPP Release 6. It is planned that 3GPP Release 6 will contain, but will not be limited
to: Multimedia Broadcast/Multicast Service (MBMS), Network Sharing, Priority Service, Wireless LAN/UMTS
Interworking, IMS Phase 2, Push Services and Presence.
4.1.5 Future 3GPP Releases
The present document addresses the evolutionary aspects of subsequent 3GPP Releases.
4.2 Interactions with other industry fora
4.2.1 Internet Engineering Task Force (IETF)
As a result of the introduction of the IP Multimedia CN Subsystem, the dependence on IETF RFCs has significantly
increased, with 3GPP defining requirements that impact the IETF work. The relationship with IETF is moving away
from one where 3GPP simply adopts the protocols as applicable (as was the case in Release 1999 and Rel-4), with
3GPP actively participating in the develop of the protocols for Release 5 and in the case of Release 6 defining the
system requirements, from which the protocol requirements can be determined and passed to IETF to provide the
solution. To coordinate that work, 3GPP has put in place the following:
- an IETF Liaison Rapporteur to work with the officials of IETF;
- tracks the dependencies on work in IETF through the 3GPP Work Plan;
- provides 3GPP requirements drafts into IETF through contributions from individuals.

4.2.2 Open Mobile Alliance (OMA)
OMA is a new industry forum, which is working on service enablers for mobile systems. The working relationship
between 3GPP and OMA is still being developed. Currently, 3GPP is dependent upon work within OMA that was
formerly being done with fora such as WAP and LIF. In this case, the requirements have been defined by 3GPP and the
protocols are being defined by OMA e.g. for LCS and MMS.
In the future there is the possibility that OMA will be defining service enablers that 3GPP will need to:
- provide interworking to;
- provide network capabilities to support the service.

5 Focus areas and Stakeholder expectations
A number of drivers have been identified for the evolution of the 3GPP system. These drivers can be categorised as expectations coming from a number of different
"Stakeholders", in that each Stakeholder has its own expectations of what evolution will deliver. Table 1 gives a summary of the stakeholders and their expectations. They have
been grouped under focus areas. Some drivers appear under more than one focus area. It is recognised that new services/functions shall provide new streams of revenue.
