Never one to shy away from the spotlight, Huawei last week shared its latest 5G network research at PT/EXPO CHINA 2016 in Beijing, noting that it has completed first-stage field test verification of 5G air interface technologies with operators in China.
The trial with China Academy of Information and Communications Technology (CAICT), China Mobile, China Unicom and China Telecom showed three times spectrum efficiency improvement. They also successfully tested flexible air interface slicing, which used a combination of technology components, Huawei said in a press release.
Network slicing is expected to be a key component of 5G. An NGMN Alliance 5G white paper (PDF) described how a network slice, namely a "5G slice," supports a particular connection type with a specific way of handling the control and user planes. The intention of a 5G slice is to provide only the traffic treatment that is necessary for the use case and avoid all other unnecessary functionality.
Huawei said that network slicing tests for three types of services have also helped to successfully implement network slice generation for millions of users, network function reconstruction and flexible deployment of the user plane in the control and user plane architecture where user plane and control planes are separated.
In recent months, Huawei also completed the first verification of high and low frequency band hybrid networking with China Mobile and released the first 5G end-to-end slicing prototype with Deutsche Telekom.
Along with China Mobile, it also won the “Most Promising MEC Trial” award at the second Mobile Edge Computing (MEC) Congress that was held in Munich, Germany, last week. The award was presented for the commercial deployment of mobile big data services based on indoor and outdoor accurate positioning.
Over the past year, China Mobile (Sichuan) and Huawei have jointly made efforts to place indoor digital networks in various hotspots, such as large shopping malls, university campuses, office buildings and sports venues. The gear is based on Huawei's LampSite solution. Combined with Huawei's Service Anchor platform, these deployments are designed to help the branch operator deliver 4G mobile service experiences and various indoor value-added services.
China Mobile (Sichuan) is planning to work together with Huawei to build smarter operator mobile pipelines based on LampSite and Service Anchor platforms to enable service localization and local video broadcasting.
