such as emergency user-equipment
positioning and Commercial Mobile Alert
System (CMAS), and evolution of IMS
architecture.

transport instead of just
Asynchronous Transfer Mode
(ATM) in the core network.

Broadcast/Multicast Services
(MBMS). Performance
specifications for advanced
receivers. Wireless Local Area
Network (WLAN) integration
option. IMS enhancements.

Release 7: Evolved EDGE. Specifies HSPA+, higher order modulation and MIMO. Performance enhancements,
improved spectral efficiency, increased capacity, and better resistance to interference. Continuous Packet
Connectivity (CPC) enables efficient “always-on” service and enhanced uplink UL VoIP capacity, as well as
reductions in call set-up delay for Push-to-Talk Over Cellular (PoC). Radio enhancements to HSPA include 64
Quadrature Amplitude Modulation (QAM) in the downlink DL and 16 QAM in the uplink. Also includes optimization of
MBMS capabilities through the multicast/broadcast, single-frequency network (MBSFN) function.

Jointly with the GSM Association on aspects of
interconnect, roaming and charging
Local Breakout is utilized for connecting IMS
media
• Optimized media path is important to reduce cost
•
Legacy Charging Accounting and Interconnect
principles should be re-used
Location requirements being addressed
•
•
Authorities in many countries require networkauthenticated location information stored for
certain sessions (e.g. for court cases)
Standards are being developped to address this

SMS and Messaging over LTE
THE Mobile Broadband Standard
LTE is packet only and hence does not natively support legacy
SMS
IMS based messaging may not be available at initial LTE
deployments
Standards were developed to deliver legacy SMS over LTE
• A device that is attached both to LTE and 2G/3G can send and receive
legacy SMS over the legacy CS core network
• Enhancements to the necessary interfaces were defined to pass SMS
between legacy CS core and EPC/LTE

The PCC framework has been further
enhanced to give operators an even wider
range of control tools
Support for sponsored data connectivity
has been added

packets is also supported
Handling of privacy policies has been

ability to differentiate machine-type
devices
• This allows the operator to selectively
handle such devices in overload
situations
• Low priority indicator has been added to
the relevant UE-network procedures
• Overload and Congestion control is done
on both core network and radio access

THE Mobile Broadband Standard
Device-to-device
Communication (D2D)
Proximity-based applications and services represent a recent
and enormous social-technological trend
• These applications and these services are based on the awareness that
two devices or two users are close to each other
• Awareness of proximity carries value, and generates demand for an
exchange of traffic between them
Direct D2D communication is also essential for public safety
services
• e.g. in case of lack of network infrastructure in disaster situations
3GPP has initiated work on enhancing the LTE-EPC platform to
support these capabilities

Regulatory features – disaster
response
Recent events have brought the different disaster response
functions of the 3G/4G networks to the forefront
• Public Warning System (PWS) provides a secure framework
for delivering Warning Messages to the devices
• The Japanese version of this system saved thousands of lives in the
recent earthquake/tsunami disaster
• Priority Services
• Mechanisms have been standardized to allow priority access to the
network services (voice calls, Internet, multimedia calls, etc…) for
e.g. government officials in the event of a mass disaster

Prospects
THE Mobile Broadband Standard
3GPP systems approach ensures
evolution to meet new service
requirements
Industrial input to 3GPP solid and
growing
LTE and LTE-Advanced are not the
end, 3GPP is now studying future
networks
LTE is an evolution path for non
3GPP systems, providing future
path for full coverage
