On September 19th, a spokesperson of China Unicom said at the China Radio Conference that the 5G standard should further serve the characteristics and needs of domestic networks. In the voice solution, VoLTE is too complicated and should consider how to simplify VoNR.
In 2018, China Unicom launched the 5G scale pilot in 16 cities in China. According to the plan, it will be pre-commercialized in 2019 and commercialized in 2020. It is reported that China Unicom's 5G network will be based on the newly frozen SA, and focus on eMBB in the early stage, and maintaining the network speed advantage of China Unicom in the 3G and 4G eras. The follow-up will combine the technical standards and the development process of the ecosystem, and actively introduce uRLLC and mMT technologies to provide digital transformation support for vertical industries such as the Internet of Vehicles and Industrial Internet.
In the promotion of VoLTE, the call of China Unicom's 4G network will fall back to the 3G network, which has little impact on the demand of users while talking on the Internet. Therefore, Unicom has a slight attitude with Votel in terms of VoLTE. different. For example, last week, China Telecom said that China Telecom will promote VoLTE as the default voice solution for terminals. It is expected that after the mature commercial period, the new terminals will be pure VoLTE, and all voices will adopt VoLTE mode.
In addition, in April this year, China Unicom said that VoLTE will have network capabilities in the fourth quarter of this year. Previously, in some parts of China, Unicom users had access to VoLTE services.
