Coquettish Rebirth

In this year, the concept of dual-card dual-standby has never been brought up at all. You must know that this concept did not appear until the 21st century counterfeit machines began to adopt the mtk solution.This so-called dual-card dual-standby is actually a patent of MTK MediaTek, or in more detail, the patent of this mtk is single-network dual-card dual-standby single-channel.What is single-network dual-card dual-standby single-channel?That means that you can only use the gs-m network, and then two cards, and you can only keep the "account" of one sim card at the front end at a time.

This kind of single-network dual-card dual-standby single-channel can be said to be a very big innovation back then. This innovation gave shanzhai mobile phones an unparalleled attraction, and even ended up making a lot of big-name brands. Chapter [-] Dual-mode dual-standby Manufacturers - such as Nokia have begun to learn!Of course, Nokia's dual-card dual-standby is likely to bypass MTK's patent, because even if it is a single-network dual-card dual-standby single-channel, there are many twists and turns in it.For example, when you can only use two gs-m cards, the simplest and most direct way to achieve dual card dual standby is to build two motherboards in the phone, but although this is simple and straightforward, But it consumes a lot of power!After all, this is the same as using one battery for two mobile phones.A better way than this method is to switch through software, but this method also has problems, because after all, if the software switches the content between the two cards, various "bugs" are prone to appear, resulting in black screens and crashes. Phenomenon.

After this "soft solution" solution, a further solution combining software and hardware appeared soon. This solution is the one proposed by Jia Hongjian to Ni Guangnan. The switching is controlled by an IC chip, and the software is only responsible for sending Pulse switching request!Five or six years after 2000, this solution was basically the most mainstream, and its solution was so mature that it was surprisingly mature—the switching request sent by the dual-mode dual-standby software in Chapter [-] actually It can be as high as one thousandth of a second to request a switch!In this way, although only one IC card is kept at the front end for a single channel at a time, the user actually feels that both cards are online at the same time!After all, no one's senses are sensitive enough to detect a delay of one-thousandth of a second!However, there is still a problem with this solution, that is, when one sim card is calling, if another sim card calls, there is no way to access it. At this time, mobile phone manufacturers have developed a very "smart" The solution is to let the sim card in the background not answer the call, but send a text message to the sim card in the foreground, indicating that there is a missed call!

On the other side, the dual-card dual-standby technology is actually just a single-network dual-card dual-standby single-channel technology, and Jia Hongjian asked Ni Guangnan to develop it. It is dual-mode dual-standby.This kind of technology seems to be invented by China Unicom in history, and it is mainly used to grab mobile customers. With this kind of mobile phone, one side has a cdma card and the other side has a gs-m mobile card dual standby, which is not particularly convenient. Does anyone else use it?

Generally speaking, dual-card dual-standby or even dual-mode chips can be added to the phs PHS system. However, people who bought PHS in China at that time were sensitive to prices. Chip, then the cost will inevitably rise and the price will also rise. The result is that no one buys the hard-working mobile phone.However, Jia Hongjian’s current time and space are different, because in this time and space, such things as PHS are not a symbol of “sex”, but more accessible to ordinary people like iPhones. Install x artifact.People in this era don't have the antipathy attitude towards arcade machines like the post-21s generation in the [-]st century. People in this era don't feel that they are worthless when they use mobile phones that everyone uses!Therefore, if the phs dual-mode mobile phones of this era are produced, there must be no need to worry about sales!

However, what is the difficulty of making a dual-mode mobile phone with the phs system, that is, the phs PHS system itself uses digital micro-cellular technology, while 2G signals such as gs-m use digital cellular technology. The difference between the two cannot be solved by adding an ic card. In any case, it takes almost two sets of motherboards to solve it!If Ni Guangnan was to develop such a technology, it can be said that Jia Hongjian didn't think how perfect it could be handled - if it is too perfect now, how will the advanced products be sold in the future?So in fact, Jia Hongjian asked Ni Guangnan to make it. To put it bluntly, there are two sets of motherboards in a PHS mobile phone, but they are not turned on at the same time, but quickly adjusted with the IC chip. In this way, the power consumption can be compared to the two motherboards. If it runs at the same time, it will be relatively small, and at the same time, it can keep both sides as standby as possible.

It is not difficult to develop such a mobile phone, at least in the eyes of Ni Guangnan, but it is a bit difficult to mass-produce such a mobile phone—a bit similar to vcd and dvd, this gs - Various patents for mobile phones are in the hands of foreigners.In this gs-m mobile phone patent pool, there are a variety of patents, and the professional point of view starts from the chip field.Even if you don't use other people's chips, start designing and manufacturing yourself from scratch, including baseband chips, including gs-mshe frequency chips, etc., but there are still places where you need to pay patent fees-that is the lowest communication protocol!

This kind of communication protocol, which is similar to the computer network tcp protocol, has to pay money if you want to follow it, which is basically unavoidable, unless you are one of the companies that have built a patent pool and can exchange authorization with others To avoid patent fees, this is why later generations of manufacturers such as Datang must develop Chinese standards such as td-cdma.However, Jia Hongjian and the others are not completely powerless to resist. You must know that Huaxia High-Tech is the only company in the world that holds the patent for phs wireless local calls!If Huaxia Hi-Tech doesn’t nod, other companies won’t be able to produce at all—after all, even the receivers on the program-controlled switches of the Ministry of Posts and Telecommunications use Huaxia Hi-Tech’s equipment. No matter how they produce PHS, they won’t be able to escape Huaxia Hi-Tech’s underlying agreement to collect money. ?

Therefore, in theory, if Jia Hongjian and the others are willing to share the phs patent with others, they can still avoid various patent fees, and Jia Hongjian's idea is exactly this!Now that Changhong has started to open up to enter this market, why not just open up more and let those international manufacturers come in to produce PHS?Let's do something good together!

For Huaxia Hi-Tech, by exchanging patent authorizations in this way, they can avoid the patent pool of gsm, and then start to concentrate on researching various chips and motherboards in gsm, and then they can produce dual-mode dual-standby, so that Another new patent!In addition to these, Jia Hongjian also felt that it was impossible for his Huaxia Hi-Tech to play within the PHS range of phs all his life. Although PHS was required to withdraw from the market in 2012 in accordance with the requirements of the country in history, after all, gsm is only now. It is a trend, and in the future the 3g network will be even more trendy. If it does not enter the mainstream now, there will be no room for improvement in the non-mainstream in the lifetime!

After letting Ni Guangnan develop the gs-m dual-mode first, Jia Hongjian looked back at Changhong's market situation.Because Changhong followed Jia Hongjian's instructions and came up with a series of small tricks, Changhong TVs on the market have been in a downturn for almost a month, and then they started to sell like crazy again! Li Dongsheng of tlc and others couldn't believe their eyes. They began to be surprised to find that it seemed that when they just started to produce new products, Changhong's machines began to increase in volume and lowered the price of the products. When it goes public, you won't be able to make a lot of money, is there any?Then when tlc finally gritted its teeth and fought a price war with the other party, the other party did not take over at all. They directly launched this market after increasing the volume, and then began to increase the volume of the next product!After such a series of series, basically a new product will be produced in a little over three days. This kind of release mode makes the people of tlc go crazy!They don't understand why Changhong's people are so good at development, and they don't understand why it has become what it is now, but one thing they can understand is that all of this must be Jia Hongjian's idea!

According to Changhong’s annual sales record of 94 million TV sets in 400, they basically had 10 models on the market that year, and each product had to produce 50 million sets!But it’s different now. They only produce about 20 sets of a color TV. The first 5 sets will be priced first, and the next 15 sets will rush to the market quickly, and then they will leave!Such a fast-moving and fast-closing wave of attacks has really greatly reduced the risk of Changhong's single product, and also increased the profit of a single product. For Changhong, that is simply a good way that Changhong has dreamed of!

For Changhong, it is a dream come true, but for competitors like tlc and Panda, it is a complete nightmare!Although the sales volume of tlc and pandas are higher than last year, but according to the data they learned in the market, they are far behind Changhong!According to the basic starting data in the current market, Changhong has almost recovered to about 80% of the market share, which is simply too scary.It's as if Changhong has relaxed his pace for a while in order to give tlc and other companies a virtual sense of accomplishment...! ! !
