On June 17, Guangzhou Pazhou International Convention and Exhibition Center staged the "speed and passion" of the mobile phone industry.
At the opening day of the 2011 CDMA World Forum and Tianyi 3G Internet mobile phone trade fair, a PTT (Push) based on China Telecom's 3G network was launched jointly by the four major industry giants: ViewSonic, Qualcomm, China Telecom and Ulead Group. -To-Talk) business solutions have set off an unprecedented storm of talkback encryption in the Chinese communications industry.
“Nothing wrong, a wave of new technology revolution, while vigorously promoting the rapid development of the communications industry, but also left the world-class problems of lack of confidentiality of the content of the call.†Qualcomm, director of business development and operator relations In an interview with a reporter from the China Business Journal, Hui said that as early as seven years ago, cluster communications began to receive great attention from the communications industry, but how to develop "one to one" as "one to many" among mobile phones. At the same time taking into account the confidentiality, plus technical standards and many other reasons, making this subject challenged the advance. "The Qchat era for solving this problem is now coming," he said.
"Powerful" Qchat
“An interim conference call will be held five minutes later. Regardless of where you are, please take a break from your work.†Mr. Zhang, sitting in a coffee shop on the Shanghai Bund, took out the Qchat cell phone and set aside a call. More than 10 middle-level officials were informed and they responded to the middle class at the same time.
This kind of Qchat with various advanced functions such as “voice QQâ€, SMS upgrade, and call confidentiality is a PTT service solution (including server solution and terminal solution) introduced by Qualcomm, and is a brand of China Telecom 3G service.†Tianyi Intercom's main push-based PTT solution is a data-based value-added service based on VoIP technology that operates under the 3G-EVDO network.
According to reports, the new mobile technology, PTT (Push To Talky), can quickly perform "one-to-one" or "one-to-many" calls, just like using an intercom phone. This feature is suitable for small and medium-sized businesses that need frequent contact and individual users who need to chat with friends and family. However, you must use a phone with this feature built-in. The PTT feature cannot be used with normal phones.
After the mobile phone has opened the PTT, just click on the corresponding button of the mobile phone, you can use your own mobile phone and the selected group to achieve "one-to-one" or "one-to-many" calls.
Unlike a walkie-talkie, which can only communicate at a short distance, a push-to-talk service can be accessed to a place covered by a mobile phone network, with almost no distance limitations. In addition to free-roaming, remote calls, ease of use, and low cost, increasing operator revenues and reducing communication costs are key selling points for Push-to-Talk.
The Qchat call process is similar to a real-world conference. There are sponsors (calling parties) of the conference. Members in the conference can be late (join later), or can leave early (quit the call without ending the call), and can also exit after Join again. During the meeting, other people or groups may be invited to join (invite members) meetings. The initiator can end the conference or no one speaks for more than a period of time. The system automatically ends the conference.
In order to ensure that mobile calls are “absolutely confidentialâ€, Qchat’s 3G-based Qchat uses “code-division multiple access†technology, which allocates one of 242 random codes for each user’s call, with a total of 4.4 trillion possible permutations. Therefore, it is inconceivable to break the password or eavesdrop on the content of the call. Pirates can only become theoretically possible. In addition, due to the use of spread-spectrum communications, the signal power transmitted to the air is extremely small, and it is extremely difficult to be “captured†under normal circumstances. Due to the above dual protection, the confidentiality of the mobile phone has been improved unprecedentedly.
"Based on Qchat's strong integration capabilities, it is bound to open up a new era of communications." Said the person in charge of Qualcomm said.
The feast of giants
In fact, as early as seven years ago, the PTT phone was unveiled at the 2004 CeBIT trade show in Hannover, Germany. However, due to technical standards and other differences, the pace of "immediate communication" technology in the market has been unable to accelerate.
“As long as there are market prospects, the pace of scientific research will never be stagnant.†As the supporter of the “Cryptography Storm†in the communications industry, Qualcomm’s director Feng Hui introduced that, at that time, Qualcomm We also started to research QTat based on the PTT technology of CDMA2000 network. At present, technologies such as "one-click communication" and "privacy" have become mature.
As a result, in 2009, U.S. ViewSonic, Qualcomm, China Telecom and Ulead Group jointly developed the Qchat business and launched a large-scale rollout to the country through the 2011 CDMA World Forum.
The responsible person of China Telecom stated that the Qchat business is based on the CDMA network. At present, China Telecom’s CDMA network has covered all parts of the country and can smoothly protect the needs of PTT mobile phones. Moreover, the company continues to increase investment in network construction and maintenance each year, which undoubtedly lays a solid foundation for the expansion of differentiated new services.
As for the four giants in the cooperation of the equity and specific models, is still not known. The reporter was informed that the United States ViewSonic Corporation, established in 1987, has professional experience in the field of protective intercom handset terminals and provided Qchat with a variety of intercom solutions.
As a technically-supported Fortune 500 company, Qualcomm Incorporated develops and delivers the world's leading creative digital wireless communications products and services based on its CDMA and other advanced digital technologies.
Shanghai Uygur Express Group is the most influential marketing and promotion agency for communication products in China. The company has a remarkable team and successful promotion cases. Its service targets are widely used by communication operators and product suppliers with high growth potential and huge added value. The group aims to help its partners achieve their business goals through advanced direct-integrated integrated marketing models such as television, newspapers and the Internet.
As a result, from the technology to the terminal to the network support, “this kind of cooperation model makes it stand out in the current mid-to-high-end smart phone market.†A securities analyst in the communications industry told the reporter that similar to the current QQ WeChat, Michao or Compared with foreign products such as KIK, PTT business solutions have more core competitiveness than simple instant entertainment, confidentiality, and cluster communication.
Creative Industry Market Outlook
Like Mr. Zhang, mobile phone users with Qchat have grown geometrically in Shanghai.
In fact, as early as October 2009, China Telecom began to test the water in Shanghai, officially started the commercialization of the cluster business, and it mainly provides the cluster call service to government and enterprise customers and industry application customers.
It is understood that Shanghai Telecom’s Qchat cluster service launch is the first time that China Telecom has launched this service on a commercial network. The commercial platform supports 100,000 users and supports other provinces across the country to carry out Qchat services through a platform that accesses Shanghai remotely.
On the system side, Shanghai Telecom’s CDMA wireless network was jointly built by Alcatel-Lucent and Huawei, and has fully supported the Qchat business function. On the terminal side, the openness of Qchat has attracted many terminal manufacturers to launch Qchat-enabled terminal products.
In 2010, Shanghai Telecom’s Qchat business successfully supported the World Expo and served in various fields such as stadiums for the Expo, security for the Expo, and urban services, laying the foundation for further large-scale promotion and application.
According to He Ning, assistant to general manager of China Telecom Tianyi Terminal Company, the applicable customer groups for the Qchat professional intercom mobile phone lock include: in government agencies, military, police, customs, industry and commerce, taxation, administrative enforcement, and fire protection; in the public service sector , Medical, communications, water, electricity, gas, radio and television and other departments; in the industry users, logistics, transportation, airports, railways, ports, petrochemicals, mining, forestry, fisheries and other departments.
“Although Qchat was launched soon, it is foreseeable that the mobile phone will rapidly grow into a huge market with its potential as its full-fledged function.†Wen Wenlei, the marketing director of UCC Group busy in the exhibition hall told reporters at the fair. Half a day morning on the opening day, there were more than 200 dealers who came to consult and they all expressed that they were optimistic about the bright future of Qchat technology.
Industry insiders expressed that the Qchat technology, a cluster service that is about to change people’s living habits, is currently the industry’s most recognized technology in the CDMA public network trunking communication technology, and the industry’s most open technology. Through a series of technological innovations of China Telecom, its Qchat technology caters to the needs of users in China. By pressing a button, people can speak and hold conference calls with people all over the country. This differentiated path decision is just another tool that China Telecom has forged in the fiercely competitive market.
