Recently, Zhejiang Mobile formally released the first MEC innovation technology that Huawei created for the 4G network, which was created by Huawei, to build the edge network computing capability, and create a high-experience, high-reliability, flexible and open intelligence for Zhejiang Mobile. The network lays the foundation for the evolution of 5G networks.
With the maturity of 5G advanced technologies such as CUPS, Massive MIMO, high-order modulation, and ultra-dense networking, applying these technologies to existing 4G networks to maximize the value of 4G networks is maximizing 5G technology utility. Powerful measures.
This article will discuss how to apply 5G CUPS technology in a 4G network to build a highly experienced MEC network for high-definition video and VR services.
In a traditional 4G network, control plane network elements and user plane network elements are deployed centrally at the central office. For a mobile video user, even the administrator of the Tencent video data center, the traffic of watching videos still needs to be forwarded by the user's face of the mobile station's central office thousands of miles away, and the network delay is greatly increased. And video traffic flows through the entire network, taking up a lot of bandwidth.
Therefore, there is no direct relationship between the mobile video experience and the content source. In the age of mobile video growth, mobile networks must be optimized to ensure the user experience.
Separation of control forwarding, user plane sinks to the edge of the network
The Huawei MEC@CloudEdge solution is a next-generation mobile broadband solution based on the Cloud Native architecture. It fully complies with the 3GPP CUPS standard protocol. It uses the 5G CUPS technology to separate the gateway control plane from the user plane. The control plane gateway is centrally configured and unified. The face is stripped from the central office, sinking to the edge of the network that is close to the mobile video user.
5G technology 4G switching control to create the ultimate video experience
In this way, the video traffic can go through the sinking user plane gateway without having to travel long distances to open up the path to the nearest content source. The network delay is shortened with the shortening of the traffic path, and the bandwidth occupation of the backbone network is also significantly reduced.
Edge DC portfolio deployment, build distributed pipeline capabilities
CloudMSE is a member of the CloudEdge family of Huawei's packet core network solutions. It is considered to be an operator's network operation capability enablement center, and is based on industry-leading service awareness capabilities to provide traffic management, network depth insight, and other functions. At the same time, CloudMSE can also provide atomic arrangement of value-added business capabilities of intelligent service chains, such as experience optimization and parental control functions, and network infrastructure capabilities such as CGNAT (Carrier Grade Network Address Translation) and DNS (Domain Name Server) functions. One-stop Gi-LAN solution.
The mCDN solution is a new content distribution system developed by Huawei for 4G+ and 5G mobile broadband. It has superior edge computing and network collaboration capabilities and is designed to meet the demand for ultra-high bandwidth and ultra-low latency service experience in the 5G era.
In the MEC network that builds the ultimate experience for high-definition video and VR services, the CGNAT and Internet DNS functions provided by CloudMSE sink with the user's face to the edge of the network and cooperate with the same mCDN deployed at the edge, thereby realizing a closed loop of the video service and further reducing The network delay and the backbone network traffic are detoured. At the same time, the service optimization capability provided by CloudMSE optimizes the transport layer and application layer data, so that various acceleration indicators such as business cardinality and download rate are significantly improved in different scenarios, and the duration of waiting for playback and the waiting time for dragging are approximately 70%. , greatly enhance the user experience.
Huawei continues to explore the path of network evolution, and proposes a smooth evolution strategy from Cloud Native to distributed networks to 5G core networks, and actively develops innovative practices for future network evolution. Currently, the CloudEdge solution has launched innovative cooperation and practice in network evolution with leading operators such as China Mobile and Vodafone.
