China Mobile: 4G voice communications business next year, 0.8 seconds time delay-4G speech communication, 4G, mobile-IT information China Mobile: 4G voice communications business next year, delay 0.8 seconds

Moving Li Yue, President of TD-LTE on global development initiatives (GTI) that included VO-LTE 4G fusion communications, voice technologies, will conduct field tests in 5 cities in the second quarter of this year, by 2015 achieve comprehensive converged communications for commercial use.

Since TD-LTE issued licences by the end of last year, China Mobile has built 320,000 base stations, covering 300 cities, sold 12 million 4G phones 4G roaming in 8 countries and regions. By the end of this year, 4G city will be 340 cities and counties were at or above the 4G covering.

"Li," said 4G commercial short, 10% per cent of traffic data, visible is increasing very fast. ”

4G strategic plan, Li said it will mainly in three aspects, VO-LTE speech development, RCS-based converged communications and high-carrier Terminal system.

Among them, the converged communications will be held in 5 cities to start field testing in the second quarter of this year, General and commercial for next year. Fusion communications contains three aspects content, new calls refers to quality more efficient faster of calls, call delay shortened to 2 seconds within, 2 a VO-LTE Zhijian only 0.8 seconds Shi extended, can support high insurance really phone, and multimedia calls, and video communications, change has communications phone coding of traditional mode; new news, fusion in smart communications within, new of news system will Subversion fiscal SMS system; new contact, in traditional number book function Shang gives social function and state information, People in the future, will complete together social relations.
