Video frequency: Interview Beijing University of Posts and Telecommunications had control over institute professor Zeng Jianqiu
When the NetEase science and technology news on May 16 news, the well-known telecommunication expert and Beijing University of Posts and Telecommunications had control over institute professor Zeng Jianqiu to be a guest the NetEase

science and technology “3G changed China” series interview indicated that the time limit did not limit the quantity the hiring by the month system charge way, is the 3G fees pattern development direction.
“At present three operators announce the fees plan is mainly collects fees according to the current capacity, when some meal forms by long charge hiring by the month system, but in fact is one kind in disguised form according to the current capacity charge way.”Zeng Jianqiu said that “the future third-generation mobile correspondence development\’s direction, should the time limit not limit the quantity hiring by the month system, this is the general consumers hopes that is also the operator should achieve.”
Zeng Jianqiu with two 50 showed that TD tries commercial more than one year of progress: “When, tried the commercial TD terminal manufacturer in last April only then several, but has now surpassed 50; On the other hand, tries commercial for one year, the user developed this year to break through 500,000 households from zero. These targets had indicated Chinese TD tries commercial this year is successful, is hopeful, in the future moreover can also succeed.”
When talking about 3G lived the change to the people, Zeng Jianqiu said: “Compares with the second generation of mobile communication, the third-generation mobile corresponded the most major characteristic to break through the second generation of mobile communication bottleneck, the band width and speed by ten times and 20 times of even over a hundred times of speed enhancements, this caused us to work the efficiency to be higher, life even more to have the appeal, brought unexpectedly, the subversive change in each aspect.”(Chen Min)
Splendid viewpoint:
Three operators proposed that must in two to three years achieve 50 million user scales, this digit means two to three years later the 3G user scale will achieve 150 million. After achieving such scale, the Chinese 3G commercial degree, the market maturity and profit degree these questions\’ answers were simple, that is YES.
TD passes through one year trying commercial, several test ratings may show the question, I usually " 5 " said with two: First “5”, our country when 08 years in April just tried the commercial TD terminal factory only then several, now has surpassed 50; When the second target, from 19 April 1, 08 started to try commercial may say that started from zero, broke through 500,000 households to this year, these targets had indicated Chinese TD tried commercial this year is successful, is hopeful, moreover can also succeed in the future.
Our country TD development biggest short board also has some people not to have the confidence to TD; Second, how melts the net in developing process and 2G, is a short board, is a difficulty; Third, the business enterprise must promote and satisfy the third-generation mobile correspondence the services standard, currently speaking is not difficultly small, is together the short board.
In the future third-generation mobile correspondence development\’s direction, should the time limit not limit the quantity hiring by the month system, this is the general consumers hopes that is also the operator should achieve.
The following is interview factual record:
NetEase science and technology: Mr./Mrs. Zeng you were good, greeted with the NetEase science\’s and technology\’s fellow net friends first.
Zeng Jianqiu: Good, each NetEase science\’s and technology\’s net friend hello, will have the opportunity very happily and everybody together to 2009 5.17 will make some exchanges.
NetEase science and technology: Thanked Mr./Mrs. Zeng, from this year 5.17 starts, three operator\’s 3G networks starts to operate, China entered the 3G time in the certain extent, how did you regard Chinese 3G market development the prospect?
Zeng Jianqiu: Our country has in January provided the third mobile communication license plate, three business enterprises started the comprehensive 3G network construction, I want to use a digit to explain that in the future our 3G development\’s prospect, three business enterprises (the China Mobile, the China Telecom and China Unicom) will propose must in 2 to 3 years achieve 50 million scales, what does this digit mean? Means 2 to 3 years later the 3G scale will achieve 150 million, after achieving such scale, the Chinese 3G commercial degree, the market maturity and profit degree these questions\’ answers were simple, that is YES.
NetEase science and technology: You had said that should take TD to develop 3G as the axle center, the policy incline can have unfairly to other two operators?
Zeng Jianqiu: It is not this, China is conforms to the global convention by TD as the third-generation mobile correspondence development\’s axle center actually, cited an example, the development of North America third-generation mobile correspondence in fact took CDMA2000 as the axle center, Europe took WCDMA as the axle center, China took TD-SCDMA as the axle center, should say that was the normal matter, this was an aspect. Second, China\’s TD-SCDMA is we proposed, had the proprietary intellectual property rights 3G standard, moreover we have established quite widespread TD alliance, develops our country\’s national industry, to develop 3G in such foundation by TD-SCDMA, is to the universe third-generation mobile correspondence contribution, therefore China takes TD as (third-generation mobile correspondence development axle center) I to believe that is very normal matter, simultaneously the TD development must have the tolerance, with other two standards (WCDMA and CDMA2000) develops in the cooperative process together.
NetEase science and technology: The country stressed that the TD development can only succeed, cannot be defeated, in your opinion, what is the TD successful symbol?
Zeng Jianqiu: Our country started to try from April 1, 2008 decisively commercial, starts to this year, through one year tried commercial to have several test ratings to be possible to explain the question, I usually " 5 " said with two: First " 5, our country when 08 years in April just tried the commercial TD terminal factory only then several, now has surpassed 50; When the second target, from 19 April 1, 08 started to try commercial may say that started from zero, broke through 500,000 households to this year, these targets had indicated Chinese TD tried commercial this year is successful, is hopeful, moreover can also succeed in the future.
NetEase science and technology: Currently speaking, what is the TD industry chain short board? Exists what major is the most problem?
Zeng Jianqiu: Our country TD-SCDMA development biggest short board also has some people not to have the confidence to TD. Actually has many people not to understand TD-SCDMA, therefore does not have the confidence; Some people somewhat knew about TD, but compares to worship foreign countries to curry favor with foreign powers, always thinks only then foreign country\’s moon is the circle, therefore I thought that the biggest short board is some people does not have the confidence to TD; The second aspect, I think how TD the short board is melts the net in the developing process and 2G, should say that this is a short board, is a difficulty. Our country in the third-generation mobile correspondence development\’s process, TD is an independent construction network, but the construction and operation national isolated network have given the China Mobile, the China Mobile must be very good to process in the developing process had the 2G network and 3G network fusion, this short board must the place which is worth taking seriously. The third short board, I think that the 3G operation and 2G operation are completely different, has very high difficulty and very big challenging. Little while ago labor letter department had released the third-generation mobile correspondence services standard one after another, looking from the standard, the request is very high, therefore I thought that the third short board is the business enterprise must promote and satisfy the third-generation mobile correspondence the services standard, currently speaking is not difficultly small, therefore is also together the short board.
NetEase science and technology: How do you appraise the China Mobile to the TD industry terminal\’s involvement dynamics?
Zeng Jianqiu: We spoke two digit in front, most starts only then several terminals, now has been over 50, I thought that the China Mobile had realized the terminal is the present TD-SCDMA short board. From past situation is this, because TD-SCDMA has not tried the commercial experience, CDMA2000 and WCDMA have many years commercial experience, the terminal are relatively quite mature, therefore the China Mobile had realized this short board, takes seriously these aspects relatively. Terminal (question), may solve in light of the present circumstances, in the future we must pay attention well with the Asian surrounding countries carry on the cooperation to develop the TD-SCDMA terminal, specially Japan and South Korea, because they have with China develop the third-generation mobile correspondence positive wish together, this will also cause us even more to see the TD-SCDMA terminal future development.
NetEase science and technology: You thought that what data traffic can play role regarding the 3G growth of user?
Zeng Jianqiu: The third-generation mobile correspondence and second generation of mobile communication biggest difference lies in the second generation of mobile communication mainly to give priority to the pronunciation service, the third-generation mobile correspondence mainly gives priority to the data traffic. Therefore, in the third-generation mobile communication service\’s developing process, I thinks that we must place the key point the data traffic the promotion and excavation aspect, because the data traffic is the future third-generation mobile foundation, is the space which the future operation income and profit grow.
NetEase science and technology: Now the 3G surfer fees standards of three operator have exposed, you thought that which kind is long on time and current capacity two kinds of fees model is the future charge way mainstream?
Zeng Jianqiu: The telecommunications charge way has two kinds, one kind is collects fees according to the current capacity, one kind is collects fees on time long. As for the future, should say that by the time charge\’s hiring by the month system is the telecommunications charge long-term development direction, at present our country three business enterprise announcement\’s fees plan is mainly collects fees according to the current capacity, although some meal forms (for example 50 Yuan package 30 hours), will look like also hire by the month, but will be one kind in disguised form collect fees according to the current capacity actually. Therefore I think in the future the third-generation mobile correspondence development\’s direction, should the time limit not limit the quantity the hiring by the month system, I think this is the general consumers hopes, is our operators should achieve.
NetEase science and technology: This year LTE technical development forum all quarters have made some discussions at on TDD and FDD fusion, you think that these two can present the fusion? What factor primarily is decided by?
Zeng Jianqiu: The whole world has two kinds of technology bases in the mobile communication, is called FDD (frequency division duplex), other calls TDD (time division duplex), these two technologies should say that respectively has the fit and unfit quality, at present in three big standards has two standards (WCDMA and CDMA2000), they mainly take the frequency division duplex as the foundation, our country proposed TD-SCDMA to take the CDMA technology as the foundation, meanwhile has the TDD technology in inside. Should say, our TD-SCDMA standard must be superior from other theory upper arm two standards, why said? Because of the FDD transmission of information mainly by one symmetrical way, is equal to 1-3 and 2-4 such transmissions, only uses the frequency band resources are quite more; TDD is online replies in according to the time delay actually, this can take advantage of the frequency spectrum resources fully. From the technical theoretical side, both has the merit, specially and frequency division union have the foundation from the theory. Looking from future development direction, because must consider the frequency spectrum resources the effective use and many kinds of technical fusions, therefore I think that FDD and TDD fuse is full of the promise together. I proposed several years ago such a viewpoint, the 3G standard will become unified standards before LTE or 4G, this viewpoint is mainly based on FDD and TDD fusion network.
NetEase science and technology: Many people said that 3G will look like ten years ago the Internet to change the life style of people equally, in your opinion, which aspects will it in affect the life of people?
Zeng Jianqiu: The third-generation mobile correspondence and second generation of mobile communication most major characteristic broke through the second generation of mobile communication bottleneck, looking from the second generation of mobile communication basic technical specification, 20 arrives at 40KBPS, the third-generation mobile correspondence technical specification is 300 arrives at 400KBPS, now after we develop the LTE technology, the band width and speed by ten times and 20 times of even over a hundred times of speed enhancements, as a result of the technical breakthrough of bottleneck, will bring the huge change to the life and the work people, some changes will be the people cannot even imagine. Based on to technical judgment, I think that in the future the message communication technology will give the life work of people to bring the unexpected change in the third-generation mobile course of communications, will cause us to work the efficiency to be higher, life even more to have the appeal, brings the subversive change in each aspect.
Zeng Jianqiu: My life and work could not leave the third-generation mobile to correspond, I have used the 3G handset externally, internally also uses the 3G handset, the 3G handset has given my each kind to experience the first aspect is the audio quality is getting better and better, the second aspect is the surfer speed must be quicker than the 2G speed, in addition can through the handset look that the television and video frequency talked over the telephone, these services lived my original 2G are more richly colorful. Simultaneously because third-generation mobile correspondence itself speed is quick, the service are also many, therefore works needs to process through 3G, exchanges is more convenient, I think, the people will come across many questions in future job and life, but 3G will change our lives, brings to us is convenient.
