What exactly is S40's intelligent system? Explain?

The serial platform is a software layer between the operating system layer and user applications, and it is a software interface layer (interface) built on the bottom operating system. Describing in professional language is the API set of application development, which provides software developers with interfaces and tools for developing applications, and provides users with UI support and multimedia application support. Perhaps readers don't know its specific meaning yet. In a sense, the Series platform is equivalent to the most widely used Windows operating system in personal computers, and acts as the main man-machine interface between users and computers. Many applications are developed based on this operating system.

Just as Windows system is divided into multiple versions, Series platform is also divided into S40 (JAVA platform based on mass market), S60 (based on mainstream intelligent terminals), S80 (based on high-end business and mobile office applications) and S90 (based on forward-looking handheld touch mode) according to product positioning. However, different from Windows system, different technical specifications are adopted for each category of the series platforms. Except for S90, which has only one 77 10, other S40, S60 and S80 have all undergone the upgrade of the operating system version. Among them, the S40 system platform has the widest user base, and its latest version prototype has been reflected for the first time in 6270. After getting the engineering prototype of 6270 first, and carrying out detailed evaluation with the attitude of the first domestic launch, many netizens responded enthusiastically to the new S40 version. Therefore, the IT World Mobile Channel presents an exploratory special report on Series40 in combination with official and related materials, without seeking everything, just asking you to appreciate the essence of s40 more appropriately, take the initiative to experience the third edition of S40, and then start a wider discussion.

Nokia's definition of S40 platform is the mass-market oriented Java mobile phone platform, which has experienced three versions of development. Compared with S60, S80 and S90, S40 is built on Nokia's own closed operating system platform. Because Symbian OS is not used at the bottom, S40 platform cannot support the development of C++ programs, and the expansibility of the operating system is limited to the application of JAVA programs.

After defining S40, we will continue to study the changes of S40 system version. At first, Nokia 765438+7250i, 66 10, 3 100 and other models could only use the main menu style of large icons, and the screen configuration was mostly 4096-color STN display and 128× 128 pixel resolution. Later, it gradually developed to. The 7200 of 65536 color TFT color screen and the 7600 of 128× 160 pixel resolution can be regarded as the last works of the first edition S40, and it can be analyzed from the screen configuration that the products in this period are ready for the transition to the second edition S40. In addition, judging from the JAVA version supported by the product, S40 model only supports the JAVA applications of MIDP (Mobile Information Device Description) 1.0 and CLDC (Limited Connection Device Configuration) 1.0, and the limitation on JAVA programs is 64KB. As for the browser version supported by S40 model, most of them are WAP 1. 1, and a few models have reached WAP 1.2. 1 or WAP 2.0.

In other respects, the models in the first version of S40 only play midi music, and only exceptional models such as 3300 and 7600 support MP3 playback. Except for model 3300, which supports MMC card expansion, other models in the first version of S40 do not support external memory cards.

The best-selling models of the first version of S40 mobile phone are 66 10, 6 100, 3 100, 7200 and so on. After extensively absorbing users' feedback for improvement and enhancement, Nokia launched the second version of S40 products in the second half of 2004. The biggest feature of S40 second edition mobile phones represented by 3220, 6230 and 7270 is that the screen configuration is generally upgraded to 65536 colors *. The nth straight model is still maintained at 128× 128 pixels, while the folding model is 128× 160 pixels, which increases the good support for the theme mode. At the same time, all S40 second edition models support JAVA MIDP2.0, CLDC 1. 1, and newly provide JAVA Bluetooth interface specification (JSR-82), wireless information interface specification (JSR- 120) and mobile media interface specification (JSR-130). The second version of S40 WAP browser is upgraded to version 2.0, which adds support for XHTML action description and WML browsing through wireless scene TCP/IP(wTCP/IP), and strengthens entertainment functions and network applications.

Strengthening multimedia function is also the progress of S40 version 2. Many high-end products have supported MP3 and AAC music playback, but the sound quality is average. In addition, at present, there are few models that support external memory cards, and only support MMC card expansion, which has certain disadvantages in universality and data transmission speed.

Nokia recently launched two S40 second edition high-end models, 6230i and 8800 with 208×208 pixel resolution. The latter also increased the color coefficient of the screen to 260,000 colors, which greatly improved the screen resolution and achieved a more delicate display effect without changing the visual area of the screen. The 8800 with 260,000 colors has reached the strongest display effect in the current S40 second edition mobile phone. Many S40 second edition mobile phones have the bottleneck that JAVA programs cannot exceed 128KB, but 6230i breaks through this limit and supports 5 12KB JAVA programs at most. It can be seen from the improvement of screen resolution and the bottleneck capacity of supporting JAVA programs that the second edition S40 is brewing a new round of reform.

The success of Nokia S40 products in the market is obvious to all, so it is imperative to increase R&D investment in this field. At the Nokia Connect 2005 conference held simultaneously in Helsinki, Finland and Singapore, Nokia officially announced the launch of a new version of Series40 platform for application development. The latest S40 version 3 will bring new opportunities for developers and operators to enter a broader consumer market. The first batch of 6270, 6280 and 6265, which will be listed in the fourth quarter of this year and adopt the third version of S40, have attracted much attention.

The third edition of Seires40 platform is a complete architecture including hardware, software and application programming interfaces. It provides an enhanced user interface and supports rich multimedia applications, further strengthens game and entertainment applications, adds a 3D image engine, and provides better support for JAVA. The common problems of the first two versions of S40, such as small screen and low resolution, have also been significantly improved. While equipped with a large screen, the resolution has been improved to the level of QVGA(240×320), and the newly designed man-machine interface can better reflect Nokia's corporate philosophy of "people-oriented technology".

As the first S40 third edition model, the 6270 is equipped with a 260,000-color TFT display with a QVGA resolution of 240×320 pixels. The perfect combination of the two brings a shocking display effect. In addition to upgrading the hardware configuration of the screen, Nokia has also designed a brand-new man-machine interface. The visual effect of the vector icons of the Chinese Zodiac is more beautiful, which strengthens the theme mode supported since the second edition of S40 and supports dynamic desktop layout, which is more in line with the user's requirements for DIY desktop style. The shortcut icon menu similar to Windows Mobile system in standby interface can be defined by users themselves, which effectively improves the operation efficiency. Excellent display effect and more humanized operation interface have laid a solid foundation for the excellent performance of the new S40 mobile phone in multimedia.

It is an indisputable fact that the old S40 mobile phone is not satisfactory in music performance, and this time Nokia has also strengthened this important detail. Taking 6270 as an example, the stereo effect of dual speakers is clear, and the newly added stereo enhancement function brings a virtual surround sound stage. Powerful music performance makes MP3 and AAC music play more thoroughly, and the effect of playing video files also gives people a refreshing feeling. According to the data, the third edition of Series40 supports streaming audio in adaptive multi-rate broadband (AMR-WB) format and advanced audio coding (AAC) format, and also supports video in H.263 format.

The new version of S40 platform continues to be well compatible with JAVA MIDP2.0 and CLDC 1. 1, and some new JAVA specification requests (JSR) have been implemented. The extended API includes interactive 3D graphics (JSR- 184) and file connection and information management functions (JSR-75). First of all, let's talk about improving the file connection specification. The third version of S40 model has improved the Bluetooth transmission function. Users can actively search for data Bluetooth devices through "New Devices" under the "Pairing Devices" menu, and support some Java API(JSR 82) of Bluetooth. The Bluetooth headset playback function in 6230i can also be found in 6270. When it is used with the upcoming Nokia Stereo Bluetooth Headset HS- 12W, players can completely get rid of the shackles of cables and enjoy the fun of portable music.

The upgrade of information management function is mainly manifested in that the new version S40 mobile phone will support OMA MMS v 1.2, and two pictures can be placed on the same page, and the maximum capacity of MMS has reached 300K K. However, at present, domestic network operators limit the capacity of MMS to 100K, so they can't enjoy the fun brought by this upgrade for the time being. Surprisingly, the 6270 uses a Mini SD card with higher versatility and data transmission speed as an external memory card. I hope this improvement can be unified on all S40 third edition models.

"Interactive 3D graphics will provide richer games, messages, customized user interfaces and visual effects of products, as well as more advanced functions," Ms. Etienne, global vice president of Nokia Forum, was quoted as saying. The 3D image engine newly added in the third edition of S40 brings richer entertainment applications, especially in games. With the support of new technology, classic games like snake can also play new flavors. With the popularity of models, I believe that the corresponding three-dimensional games will become more and more abundant, and the pleasure brought by mobile games will continue to increase.

Sony Ericsson K750c and W800c blew the horn of 2-megapixel shooting, and Nokia took the lead in responding with 2-megapixel Nseries. The subsequent emergence of 6270 and other products also marked the rapid popularization of the term 2 million pixels by Nokia. Changing the disadvantages of previous S40 models, a new generation of S40 products, represented by 6270, began to support full-screen framing, and at the same time, the shooting function was also enriched. In the past, the S40 model only recorded photos, and evolved into photos with performance value on the 6270. Although the effective pixel of the camera is not the standard for judging the third edition S40, we believe that supporting full-screen framing and enhancing shooting function settings will be the * * * characteristics of the third edition S40 model.

The third edition of Series40 platform is an important part of Nokia's platform strategy to support mobile application development. The new series of products based on high performance will bring more multimedia applications and services. By providing a consistent technical platform among different mobile phone models, Nokia's developer platform method can maximize the scale of business opportunities for developers, while minimizing the possibility of porting applications and services between different mobile phones, effectively avoiding R&D investment for different mobile phones. Developers can build core functions based on platform technology and optimize applications according to the technical expansion of user interface and specific target devices, such as: creating various themes to realize personalized customization of user interface appearance and sound effects; Provide enhanced music experience and promote the application of mobile multimedia.

Compared with the first two versions of the 40 series, the third version of the s 40 mobile phone will make a high-profile appearance with top audio-visual configuration and powerful multimedia functions, so that Nokia's humanistic concept has always been reflected in the intuitive surface performance. Inheriting the fine traditions will undoubtedly make Nokia mobile phones "pay equal attention to intelligence and beauty". From the general direction of mobile phone development, the progress of the third edition S40 is worthy of recognition. A more compatible and open software platform will provide more opportunities for relevant developers, and S40 system will be continuously improved under complementary conditions. From the consumer's point of view, the model equipped with the new version S40 will bring better audio and video enjoyment to users, and the increase of 3D image engines can also greatly enhance the game fun of players. What we can expect here is that the third version of S40 will once again lead the mainstream of mobile phone development and provide operators with more exciting and humanized mobile life enjoyment.

On the Influence of the 40th Edition of Nokia

On June 13, 2005, at the Nokia Connect 2005 conference held in Helsinki, Finland, Nokia announced the launch of the third version of Series40 application development platform, which brought new opportunities for developers and operators to enter a broader consumer market. According to official information, the third edition S40 has revolutionized Nokia's long-standing weakness in sound and sound effects. For many mobile phone users, the first impression of a mobile phone is undoubtedly its sound and sound effects. In the third version of S40, Nokia changed the screen resolution from 128× 128, 128× 65438+ to. In terms of sound effects, the realistic surround virtual sound field is enough to make the leading model feel ashamed. Behind the powerful melody effect, the remarkable progress of S40 third edition actually lies in the more powerful Java performance and multimedia performance based on melody effect.

The new platform brings streaming video and audio functions to the mass market, including supporting the latest messaging, browsing, music and video standards. The third edition of Series40 also includes the functions provided by the previous edition, so that Java developers can use the functions provided by MIDP2.0 and CLDC 1. 1, as well as OMA digital rights management and client management standards. The third edition of Sereis40 platform has realized some new Java specification requirements (JSR), and the extended API includes interactive 3D graphics (JSR- 184) and file connection and information management functions (JSR-75).

It is estimated that by the end of June 5438+February 2005, the number of mobile platform terminals developed with Nokia S40 platform will exceed 300 million (data citation/main/0,010 _ 20, 00.html). How to make 300 million terminal and non-terminal users have a stronger sense of brand belonging also largely determines whether Nokia can continue to be the leader in the world mobile phone market. The timely launch of S40, the third edition, can effectively increase the brand sense of belonging of these users, push the long-lost music effect to the leading position in the industry, increase stronger Java capabilities and multimedia capabilities, and more importantly, Nokia's consistently excellent reputation and excellent humanized function design and operation. In the near future, the models developed based on the third edition S40 will have unparalleled advantages.

In order to meet the demand of mobile phone users to access the Internet in the future, the third edition S40 also strengthens the function of network connection, and realizes the open mobile alliance OMA) browsing v2. 1, which not only provides wap2.0 browsing, but also provides XHTML mobile description browsing through wireless scene TCP/IP(wTCP/IP). Now we have realized the support for ECMAScript and cookie. The update of browser version and the further enhancement of network functions have laid a good foundation for the third version of S40 to play streaming media. On the basis of the second edition of weak streaming media, the third edition of S40 supports AMR-WB technology, which has been selected by 3GPP as the broadband standard for GSM and the third generation wireless WCDMA applications, which also indicates that the third edition of S40 will exert its strength in 3G networks, and 6280 is one of the representative models. At the same time, it also supports AAC advanced audio coding format and H.263 format file merged from AMR format and.3pg format file.

Global 3G services have been in full swing, and as an industry leader and standard setter, Nokia has taken the lead in further strengthening the core functions of mobile phones, laying the foundation for fierce 3G competition in the future. The functions of web browsing and streaming media playing, which are widely used in 3G networks, have been comprehensively enhanced in S40, the third edition, which also proves Nokia's determination to continue to dominate 3G competition.

Following last year's megapixel shooting function and this year's music mobile phone concept, many people in the mobile phone industry predict that the biggest attraction of the mobile phone industry next year will be mobile games. On the basis of effectively ensuring sound and sound effects, a more powerful game engine will make mobile games once in the "forgotten corner" become another new highlight of mobile phones. On the S40 platform model of the third edition, the game performance has also been greatly improved, just like the 3D snake pre-installed on the 6270 that has been evaluated is enough to prove Nokia's efforts to reach new heights in mobile games. Looking back, since the first built-in game 6 1 10, Nokia has been committed to developing the mobile game market. Although mobile games have not yet become the profit growth point of mobile phone manufacturers, Nokia's foresight and foresight are beyond doubt. Undoubtedly, Nokia's game progress is not achieved overnight, but the result of years of intensive cultivation and accumulation.

The snake seen on the 6270 is only a preliminary verification of the game ability of the S40 third edition model. In the foreseeable future, as more third-party software vendors are familiar with the game development software, platform and development environment of the third edition, more third-party software vendors will present more and more wonderful mobile games. With the continuous strengthening of mobile phone network access speed and the high-speed access speed brought by 3G network, more colorful 3D online games will continue to land on the mobile phone platform. Whoever can get it ready as soon as possible can share a bigger piece of cake.

The release of the third version of S40 platform has an impact not only on Nokia itself, but also on the whole mobile phone industry. Every move of the mobile phone giant from Finland is enough to influence the industry, let alone release such an important platform. First of all, the S40 platform model played a key role in the Nokia Summit, and many revolutionary breakthroughs in the third edition are bound to become the benchmark of the industry again. As far as sound and sound effects are concerned, will the models with QVGA resolution on non-smart phones become standard and virtual surround sound in the next few years, combining more powerful Java performance and game performance, plus higher network access function and streaming media playback ability. All these elements will become the basic conditions for non-smart phones in the future. The improvement of hardware performance will inevitably lead to the upgrade of software, and it is just around the corner to enjoy more powerful functions and entertainment performance on mobile phones.
