Nov. 14 (Bloomberg) -- China Mobile Ltd., the world's biggest wireless carrier by users, rose the most in six years in Hong Kong trading on speculation that high-speed mobile-phone services may be introduced in time for the Beijing Olympics.

The Beijing-based company's shares rose 9.2 percent to HK$140.80 at the end of trading in Hong Kong today, the biggest one-day increase since April 2001. The stock led gains by all four of China's Hong Kong-listed telephone operators.

China Mobile's parent is expected to finish building trial third-generation mobile networks using a domestic technology in eight cities by the end of this year, Chairman Wang Jianzhou said yesterday. Completion of the networks may allow the introduction of 3G services before next summer's Beijing Olympics, said Michael Chen, vice president of research at CSC Securities HK Ltd.

``China Mobile finishing its trial TD-SCDMA networks by the end of this year is a positive for the market,'' said Chen, who rates China Mobile shares ``buy.'' ``It would bring us a step further towards the issuing of 3G licenses.''

China may offer 3G services based on the homegrown time division synchronous code division multiple access, or TD-SCDMA, standard during the Olympic Games in August next year, ZTE Corp., the country's second-biggest phone-equipment maker, said Nov. 13.

Beijing Olympics

``The Olympics are a good testing ground for the new technology,'' Shen Donglin, vice president of wireless technology at ZTE's U.S. unit, said at a press conference in Macau Nov. 13. The games can generate ``attention from the world for this technology,'' Shen said.

The country's telecommunications regulator hasn't set a timetable to issue licenses to operate 3G services, Lou Qinjian, a vice minister at the Ministry of Information Industry, said on Oct. 18, as the government studies plans to reorganize the nation's phone industry.

The government favors plans for phone operators to merge in order to reduce the number of companies in the sector to ensure profitability, ABN Amro Holding NV analyst Wendy Liu wrote in an Oct. 16 report. Fixed-line carriers China Telecom Corp. and China Netcom Group Corp. may buy the mobile-phone networks of China Unicom Ltd. in a restructuring of the industry after the 2008 Olympics, Liu wrote.

``The main aim for the government in restructuring the carriers is to make the industry more competitive and that will be most beneficial for the fixed-line carriers,'' CSC's Chen said. ``I expect we'll have restructuring before the Olympics and that 3G licenses will come soon after that.''

China Telecom shares rose 8.1 percent to HK5.75 at the trading close, the biggest gain since Oct. 11. China Netcom rose 5.2 percent to HK$21.00, the largest increase in a week, and China Unicom's share gained 6.2 percent to HK$15.44, the most since Oct. 29.

Hong Kong's benchmark Hang Seng Index rose 4.9 percent, the biggest increase in more than two months, after better-than- expected earnings at Wal-Mart Stores Inc. eased concern the U.S. economy is headed for a recession.
