While some 4G mobile 4G of feeling voice delay, however, said Li Yue, President of China Mobile, 4G has a shorter time delay characteristics, and China Mobile Volte in development and commercial issues are being addressed.

China Mobile Chairman XI guohua said, is expected to 5G times, wireless network transfer rate is up to fibre access rate and should be used is zero delay, there are billions of device capabilities.

He also said that 4G will have lower costs. 3G and 2G, and a significant reduction in cost and a significant reduction in cost compared to 4G and 3G.

About speech delay problems 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. Converged communications contain three parts, faster more efficient call new call quality, call to shorten the delay within 2 seconds, only 0.8 seconds delay between the 2 VO-LTE, to support the high-fidelity, multimedia telephone calls, video communications, changing the traditional patterns of communications telephone numbering.

Li also said the 4G and better spectral efficiency, 4G has a much shorter delay. He said, " we can quantitatively explain 3G time we delay to 100 milliseconds with Internet access, while the 4G is 20~30 milliseconds ".

In technical parlance, 4G format used by mobile phone of China Mobile compared to the 3G model of the TD-SCDMA mobile phones reduces wireless network delay; when using user latency is less than 0.05 seconds, only 3G of the one-fourth. It is described as, even in high-speed driving conditions of hundreds of kilometers per hour, moving 4G still provides services.
