Ringing in an Evolution

LTE, designed to operate on 4G spectrum-notwithstanding

its non-complete characteristics for 4G optimization-seems to be the most-talked

about technology option today, combining great speed and working on a preferred

radio frequency level. With the Indian government considering introducing 4G

before 3G on a mass scale, LTE solutions hold special significance.


3G Americas has published a report titled, 'The benefits

of SON in LTE', to increase the understanding of the improvements in network

management that have been developed through 3GPP standards, Release 8, Release

9, and beyond.

LTE SON will thus leverage network intelligence, automation and network

management features to automate the configuration and optimization of wireless

networks. Hence, this will increase efficiency, while simultaneously improving

network performance and flexibility.

SON comes at a time when wireless carriers' networks have increasing mobile

broadband demand and a high level of complexity, which serves as an advantage.

Since there is a huge increase in data usage in the recent times in the

telecommunications sector, prompting operators to continue efforts to improve

network management capabilities. LTE SON will help to efficiently meet the

demands of this new mobile broadband world.


Initial SON solutions offered in the 3GPP Release 8 specifications, which

were completed in March 2009, include features such as automatic inventory,

software download, neighbor relations and PCI assignment that would be built

over 3GPP network management architecture. LTE SON features begin with 3GPP

Release 8 and evolve with the expected LTE network evolution stages. In 3GPP

Release 9, other SON features are addressed, such as the optimization of

coverage and capacity, mobility, RACH, load balancing and support of SON

features in multi-vendor network environments.

Data Call LTE Solutions

Class 3 terminals are expected to be the first widely used commercial LTE

terminals, when they will be launched later in 2010. Nokia Siemens Networks and

LG Electronics have gone a step ahead and achieved an LTE downlink data transfer

rate of 100 Mbps, the maximum speed for a Class 3 LTE terminal. This data call,

operating a Class 3 terminal at its 100 Mbps limit, thus demonstrates

significant progress towards commercial LTE.


The process for this data call made use of Nokia Siemens Networks' LTE radio

equipment including the flexi multi-radio base station, its evolved Packet Core

network elements and standards compliant software along with a pre-commercial

LTE USB modem from LG Electronics.

Multimedia LTE Solutions

ZTE has also announced the launch of its new generation IMS 6.0 solution that is
designed to meet the requirements of the current network transformation for 4G/LTE

in mobile and fixed fields.

Accordingly, the IMS 6.0 solution offers a variety of multimedia solutions

such as converged conference, telepresence, surveillance, gaming, streaming, and



ZTE's IMS 6.0 solution also provides enhanced policy based resources and

charging control functionality to resolve issues with increased packet traffic.

For the large flow of LTE data, it supports user based and service based QoS

policy control to ensure better quality.

IMS 6.0 solution offers an enhanced version of ZXUN xAGCF, which is the core

network element in the PSTN/ISDN emulation. ZXUN xAGCF supports a variety of

legacy interfaces including POTS, V5, ISDN BRI / PRI, H.323, and supports the

seamless integration of the current OSS/BSS, integrating with existing services

to provide a consistent user experience.

In addition, IMS 6.0 solution makes use of cloud computing and distributed

design to reduce network complexity, improve system robustness and increase the

efficiency of building networks with the lowest possible TCO for the critical

transformation period.


As LTE emerges as a frontrunner for 4G mobile network transformation,

operators are looking to provide users with higher performance, greater

bandwidth and broader network coverage while maintaining control revenue.

Further improvements and integrated solutions for LTE will thus, only spur on

further interest in its implementation with more Indian-foreign collaboration,

much to the betterment of IT enterprises in India and abroad.
