In 2018, the VoLTE era is late
On April 12th, when everyone talked about 5G, Internet of Things, artificial intelligence and driverless, it seems to ignore the VoLTE in the 4G era. There is no doubt that China Mobile is the best in developing VoLTE, and there are already 200 million commercial users (as of the end of December 2017). According to China Mobile's 2017 financial report, China Mobile's 4G subscribers increased by 114 million in 2017, with a total of 650 million, and 4G penetration rate reached 73%. The total number of VoLTE HD voice customers reached 200 million. In 2018, China Mobile was granted an FDD license. As a result, China Mobile’s 4G penetration rate will be greatly improved. In addition, after the voice service was relocated to LTE, China Mobile decided to use IPv6 for VoLTE and no longer adopts the method of converting with IPv4. The day before yesterday, it was reported that the first batch of China Telecom's VoLTE was opened in 10 provinces and cities nationwide: Jiangsu, Guangdong, Fujian, Sichuan, Hunan, Anhui, Zhejiang, Hubei, Yunnan, and Shanghai. However, it was later confirmed by China Telecom: VoLTE calls are undergoing internal technical testing and are informally commercial. As early as June 2016, China Telecom's first 800M band VoLTE phone was opened in Shenzhen, Guangdong. According to China Telecom's 2017 financial report, in 2017, China Telecom added 280,000 new base stations, with a total of 1.17 million station sets, and built a high-quality, full-coverage 4G network with high and low frequency synergies to simultaneously form VoLTE HD voice commercial network capabilities. In terms of terminals, last year China Telecom demanded terminals: terminal manufacturers must support 800M from October 1, 2017; on October 1, 2017, models with more than 1,000 yuan must support VoLTE, and 3,000 yuan from April 1, 2018. The above must support dual-card dual VoLTE; in July 2017, the test will support NB-IoT terminals. In February 2018, Lu Liangjun, deputy general manager of China Telecom Group's marketing department, said: "China Telecom will launch full Netcom 3.0 version in 2018. The most important thing for Netcom 3.0 is the upgrade of VoLTE. With the advancement of Netcom 3.0 this year, Telecom users will really enjoy a clearer and more stable voice call." It is reported that the official commercialization of China Telecom VoLTE will be realized within the year. China Unicom is among the three operators with the fewest news. Only in 2016, the whole network trial commercial VoLTE was carried out, and in early 2016, the Henan Unicom VoLTE network has been trial-commercialized and became the first province in China Unicom to complete all tests in all pilots. During the 2017 World Mobile Communications Conference Shanghai Expo, China Unicom and Ericsson and Qualcomm jointly announced the first successful implementation of the eMTC (CAT-M1) VoLTE-based application demonstration on a global scale. At the end of last year, some users of Beijing Unicom found that the VoLTE function can be used on some Android phones that support this function. The status bar of the mobile phone displays the “HD†logo, which can be dialed normally using VoLTE. During the call, the network remains in the call. 4G status. Users who have not opened the service before can also dial 10010 customer service directly, and the customer service will also open 4G+ services for users at the same time. The advantage of entertainment tablet lies in having a powerful chip and excellent hardware. If you want to play various online videos on the tablet and run various software smoothly, the performance of the hardware is an absolute prerequisite. In addition, a high-speed and stable WIFI module is also required, which must be compatible with multiple 802.11 B/G/N protocols at the same time, so that the webpage can be loaded instantly when the webpage is opened, and the online video can be played smoothly. So hardware is the premise and foundation, without good performance everything else is empty talk.
