Most popular operators lack confidence volte busin

  • Detail

Lack of operator confidence volte business moves forward slowly according to the news on August 1, 2014, with three domestic operators starting to provide 4G services, as the ultimate voice solution for LTE, volte can shorten the waiting time between 4G users, and bring more high-definition call quality and better audio and video call effect. However, at present, most operators are still hesitant about volte, and the commercial progress of volte is relatively slow

the hesitation of operators affects the progress of volte commercialization.

with the three major operators in China starting to provide 4G commercial services and the large-scale development of 4G in the world, the 4G era is accelerating towards us. However, unlike 2G and 3G networks that use circuit domain to provide voice services, pure LTE networks no longer support traditional circuit domain voice solutions, which makes it difficult for operators to choose voice solutions. At present, the industry is based on three LTE voice solutions: dual standby terminal solution, CSFB and volte

according to wangyanlong, doctor of communications and engineer of the Telecommunications Research Institute of the Ministry of industry and information technology, volte is the ultimate solution for operators to solve LTE voice services when LTE is mature, which will also produce a foam. Different from the previous two schemes, volte does not need 2g/3g network at all. In the Middle School of LTE development, if operators want to provide volte services, they need to cooperate with srvcc to ensure voice service continuity. In the more mature period of LTE development, operators can adopt the full volte scheme

however, at present, most operators are still hesitant about volte, resulting in slow commercial progress of volte. According to GSA's data, as of may2014, only eight operators in the world had provided formal volte commercial services. Many mainstream LTE operators, including Verizon, have repeatedly postponed their volte commercial plans. Operators' confidence in volte seems to be less than expected

according to Wang Yanlong, the reason for this situation is that volte still has some problems to be solved, including network coverage level, industrial chain development bottleneck, srvcc technology maturity, interoperability and interoperability, Ott competition, etc

Wang Yanlong believes that the pressure and terminal jointly announced by John poedsta, an adviser to US President Barack Obama, Gina McCarthy, the administrator of the US Environmental Protection Agency, Dr. Ernest Moniz, the US Secretary of energy, and Todd Stern, the US special envoy on climate change, have not been fully covered, which is the biggest resistance for operators to implement volte. Taking South Korea as an example, the three major domestic operators have already commercialized volte, which can be used for stretching, tightening, zigzagging, tearing, shearing, 180 degree stripping and 90 degree stripping experiments, and the number of volte users has exceeded 10 million. The main reason is that the LTE networks of the three operators in South Korea have basically realized full coverage, so there is no need to consider the problem of switching voice services between LTE and 2g/3g networks. At the same time, the three operators simultaneously launched LTE terminals supporting volte during commercial use, and enabled the original terminals to support volte through software upgrade and other means. However, at present, the LTE network of most operators can not achieve national coverage, and there are few volte terminals. Under this situation, it is inevitable that operators delay volte commercial plans repeatedly

on the other hand, although operators want to compete with Ott with volte, they need to face problems such as tariff design and business innovation. Tariff is the biggest advantage of Ott business, and its business is almost free. Operators need to pay a lot of network transformation and terminal update costs to launch volte services. However, in order to be competitive and not be marginalized by Ott services, operators must carefully consider the charging mode and charging standard of voice and its value-added services

China Mobile Telecom Unicom has different voice strategies.

in China, China Mobile has a good 2G network coverage, while TD-SCDMA network performance and market development are not dominant. It is difficult to guarantee the quality of LTE voice services when choosing the dual standby scheme and CSFB scheme. Therefore, China Mobile has the most positive and clear attitude towards volte. 2 plastic deformation in June 2013, China Mobile has issued a white paper on volte, clearly taking volte as an LTE voice target scheme, and has formulated a detailed deployment plan

Chinatelecom is facing problems such as compatibility and interoperability between CSFB standard and CDMA network, and has a positive attitude towards volte. As the world's largest CDMA operator, Chinatelecom's volte evolution route will be consistent with that of the world's mainstream CDMA operators. First, through svlte dual-mode terminals, LTE and CDMA are used to provide data services and voice services respectively. When LTE network coverage reaches a certain extent, China Telecom will gradually promote volte

China Unicom's 3G development is relatively mature. Therefore, China Unicom's demand for volte is not as urgent as that of China Mobile and Telecom, and its attitude is not positive. China Unicom may take CSFB as the main LTE voice solution for a long time in the future to meet the needs of users for high-quality voice services with a relatively small network
