Those skilled in the art can understand that words such as "first" and "second" are not intended to limit the quantity and execution order.

In the 4G era, applications such as high-definition video and online games have put forward high requirements for network delay. With the advent of the 5G era, emerging industries and emerging services such as telemedicine and VR/AR have put forward almost stringent requirements for network delay. Low-latency networks have become a development direction that operators pay attention to. With the rapid growth of 4G users and traffic, the current centralized deployment of S/PGW and the multi-layered network architecture of the bearer network cannot meet the large bandwidth requirements of users. The network bandwidth has doubled, and the demand for network expansion has grown exponentially. By optimizing the currently centrally deployed S/PGW, using the content delivery network CDN (Content Delivery Network) to sink the content source, rationally plan the data flow, improve the transmission efficiency of the bearer network, and create an efficient and intensive large-bandwidth network. The foundation and key to successful business transformation. Currently, various mobile and fixed network services are controlled and carried through independent networks. Construction, management, and maintenance cannot achieve unified integration and scheduling of resources, resulting in low investment efficiency and high maintenance costs.

As shown in Figure 1, the main services of the existing network include broadband services, IPTV (Internet Protocol Television) services, dedicated line services, virtual private network (VPN) services, and mobile network data services. The broadband service uses the Ethernet point-to-point communication protocol PPPoE (Point To Point Protocol Over Ethernet) protocol to access the Internet through the broadband remote access server BRAS (Broadband Remote Access Server). The IPTV service uses the IP protocol IPoE (Internet Protocol over Ethernet) on the Ethernet to access the Internet through the BRAS. The private line service uses static/dynamic routing protocols to access the Internet through the Service Router (SR). The VPN service adopts the Layer 2/Layer 3 Multi-Protocol Label Switching Virtual Private Network (Layer2/Layer3 Multi-Protocol Label Switching Virtual Private Network) protocol to form a network through the service edge router PE. The mobile network data services are converged and converged to the core network S/PGW through the local integrated service optical transport network UTN (Universal Transport Network Over Fiber), local bearer network, and backbone bearer network, and then access the Internet through routers. The problems existing in the existing network architecture are: mobile network services and fixed network services are controlled and carried by independent networks, and mobile network services need to be backhauled to the provincial central S/PGW through a dedicated bearer network, and connected to the Internet through a Gi router. . The existing S/PGW (Service Gateway for Mobile Network Data Service) is deployed in a centralized manner, resulting in the bearer of mobile network data services (as shown in Figure 2) across three networks (local UTN network, local bearer network, and backbone bearer network) , The transfer level reaches 7 to 10. The traffic doubles, and the bandwidth expansion requirement of the equipment board increases by 14 to 20 times. With the rapid growth of mobile network traffic, the multi-layered network architecture of the existing bearer network can no longer efficiently support business needs. The access, authentication, and forwarding methods of various services in the existing fixed network are different, especially the tightness of coupling between control and forwarding of different services is different. The broadband service is based on PPPoE. Since the point-to-point protocol PPP (Point to Point Protocol) and PPPoE two-layer encapsulation are used when forwarding data packets, the control process needs to parse each PPP packet, that is, the control process participates in the forwarding of data packets. Such a strongly coupled access method cannot realize the separation of the control plane and the forwarding plane. The tight coupling between forwarding and control of PPPoE makes it impossible for BNG to separate control and forwarding. The existing S/PGW (Mobile Network Data Service Gateway) and CDN content sources are all deployed in a centralized manner in the province, and are placed in the provincial core computer room. Users can access the transmission of high-bandwidth and low-latency services (such as games and high-definition video). Long distances, many forwarding hops, and packet loss and congestion during hotspots lead to extended access times, poor user experience, and high capacity expansion costs.

In order to meet business requirements such as ultra-low latency, low freezing, and large traffic, the industry has proposed edge cloud solutions, but the existing network architecture does not support mobility management of edge clouds, and there is no effective solution to the mobility problem of accessing edge clouds. . In the existing network architecture, the mobile network data service gateway S/PGW is deployed in the core cloud. When the mobile terminal moves from one edge cloud service area to another edge cloud service area, the service traffic is uniformly accessed from the core cloud to access the Internet. For business applications, the business application server needs to know the network location mapping relationship between the mobile terminal and the edge cloud, but the mapping relationship information cannot be obtained directly, so the business application server cannot locate the real-time network location of the mobile terminal, and cannot schedule the nearest edge cloud as a mobile terminal. The terminal provides services nearby, so it cannot provide the same quality of service experience and ensure the continuity of the service experience; because the edge cloud cannot provide continuous services for cross-regional mobile terminals, the business application scope and deployment promotion of the edge cloud are limited.

Based on the above technical background and the problems existing in the prior art, referring to FIG. 3 , an embodiment of the present invention provides an edge cloud mobility management system TX.

The services used by the fixed network device 90 include one or more of the following: broadband services, IPTV services, dedicated line services, and VPN services.

The service access request of the mobile device 30 passes through the UTN access device 40 in turn. After the UTN convergence device 50 converges, it accesses the S/PGW-U201 to complete the transmission of the service access request, and then accesses the MSG-U202 for data forwarding to the edge. The cloud service application device 203 , and the edge cloud service application device 203 sends the mapping relationship with the mobile device 30 to the core control device 101 . The data traffic of the mobile device 30 passes through the UTN access device 40 in turn. After the UTN convergence device 50 converges, it is connected to the S/PGW-U201 to complete the transmission of the mobile service request, and is connected to the MSG-U202 for data forwarding; The control signaling is connected to the S/PGW-U201 through the UTN access device 40 and the UTN convergence device 50, and then sent by the S/PGW-U201 to the S/PGW-C103, and completed by the S/PGW-C103 in cooperation with the S/PGW-U201 Access control and resource management of mobile services; the mobile device 30 may be a mobile device, such as a mobile phone, a notebook or a tablet computer, and other mobile devices with communication and network services.

The fixed network device 90 is connected to the MSG-U202 through the SW60 for data forwarding, and then the MSG-U202 is connected to the Internet. In this embodiment, a plurality of MSG-U 202 are provided. The services used by the fixed network device 90 include one or more of the following: broadband services, IPTV services, dedicated line services, and VPN services, where IPTV is Internet video, and VPN is virtual private network. The fixed network device 90 can use a broadband remote access server BRAS (Broadband Remote Access Server), a full service router SR (Service Router), a service provider edge router PE (Provider Edge), a broadband network gateway control device BNG (Broadband Network Gateway), etc. A variety of devices are converged and accessed, and the MSG-U202 is unified to access and bear to the edge cloud service application device 203, which simplifies the structure and reduces the construction cost.

For example: in the scenarios of business applications such as cloud games, the background rendering of cloud games (such as sound, image processing, etc.) uses higher image resolution, high-fidelity sound effects, and 3D image effects to achieve cool effects. , the calculation amount is huge, and stronger computing and storage capabilities are required. In order to reduce the hardware configuration requirements of the terminal, these computing tasks need to be placed in the edge cloud, and the calculation results are stored in the edge cloud.
