Nokia Siemens Networks and Chinese firms Huawei Technologies Co Ltd and ZTE Corp as they try to lower their costs.
Alcatel and Reliance Communications formed in 2008 a joint venture which was managing the Indian firm's network in a five-year, $750 million deal. That joint venture will end after the award of the new contract, Singh said.
The new contract covers management of mobile, fixed-line and corporate networks, Reliance Communications said.
Reliance Communications, controlled by billionaire Anil Ambani, had 134 million Indian mobile phone customers as of November, according to data from the sector regulator, ranking third in a market of nearly 900 million mobile users.
The deal is also a boost for loss-making Alcatel-Lucent, which has been hit by competition from low-cost Chinese rivals and lower spending on network gear by global telecoms operators.
