Build Quality CDMA Network Hand in Hand with Reliance

1　 Background

Founded in 1999, Reliance Communication Corporation (Reliance for short hereafter) is the largest CDMA operator in India, and the third largest CDMA operator in the world. Adopting flexible market policies and various price packages, Reliance got a favorable position in the intense competition of the Indian market. With dramatic increase of user quantity, traffic increased greatly. The existing network capacity has become the dilemma of user development. It’s urgent to expand the network soon.

On the other hand, Users rapidly increased in Indian telecom market. A lot of emerging operators appeared, which made market competition become fiercer. To keep competitiveness and win the market, Reliance decided to work together with ZTE to guarantee quick user increase, consolidate dominant position, and create high-quality network.

To achieve the goal of fast large-scale capacity expansion for Reliance, ZTE went all out to improve network construction efficiency. The construction and customer acceptance of 38 sets of BSC, 20 sets of core networks and 15 sets of gateway only cost half a year. Stable and fast network construction increased users quickly for Reliance, and laid a solid foundation for competitiveness consolidation and improvement.

Reliance’s CDMA users have reached 36 million by April 2008 with an increase of 1 million for each month.

Reliance hopes that it could create a future-oriented All-IP network based on its rich IP transmission resource so as to reduce network OPEX and improve network competitiveness. ZTE All-IP equipment has large capacity, small volume and low consumption. ZTE solution is mature, stable, and smooth in evolvement towards future network. Besides, ZTE flat network architecture perfectly suits large-scale networking. All these features meet the requirements of Reliance by solving its problems of extremely high traffic, high user sensitivity and microwave transmission. ZTE All-IP solution could save up to 60% transmission resource and 30% vocoder coder, which distinctly decreased voice delay, won high user satisfaction and great appreciation from Reliance.

ZTE customized a whole set of solution for Reliance, taking Reliance’s features into consideration:

●  Core network networking solution connects the switching end-office in Circle (official administration unit in India) with the gateway office. The whole network architecture is clear and easy to manage by gateway interconnection between Circles.

●  21 sets of gateway offices are distributed in each telecom Circle in India, connecting equipment from other vendors, stably supporting the whole network and providing high quality services for users.

●  Providing high quality network planning and optimization solution, which effectively extends terminal standby time, improves voice quality, improves edge user access rate, and guarantees stable implementation of the expanding network with high traffic.

●  Considering Reliance’s features of large coverage in remote areas, small capacity needs, and IP transmission requirement, ZTE customized highly integrated indoor/outdoor site. Compared with traditional site, ZTE-built site can reduce 50% consumption. Board number is greatly reduced. TCO is effectively reduced.

To achieve the goal of fast large-scale capacity expansion for Reliance, ZTE went all out to improve network construction efficiency. The construction and customer acceptance of 20 sets of core networks and 15 sets of gateway only cost half a year, then expanded to 26 sets of core networks and 21 sets of gateway. Stable and fast network construction increased users quickly for Reliance, and laid a solid foundation for competitiveness consolidation and improvement.

ZTE Solution Highlights:

●  All-IP CDMA network and gateway office with the largest capacity in the world

●  Industry-leading 3G All-IP solution saves up to 60% transmission resource and 30% vocoder coder.

●  SIP-I is adopted between gateway GMSCe
