It should be pointed out that , when the difference is not emphasized, the meanings they want to express are consistent.

In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same or similar items with basically the same functions and functions. A skilled person can understand that words such as "first" and "second" do not limit the quantity and execution order.

In the 4G era, applications such as high-definition video and online games put forward high requirements on network delay. With the advent of the 5G era, emerging industries and services such as telemedicine, VR/AR, etc. have almost stringent requirements on network delay. Low-latency networks have become the development direction that operators are concerned about. With the rapid growth of 4G users and traffic, the current centralized deployment of S/PGW and the multi-layer network architecture of the bearer network cannot meet the large bandwidth requirements of users. When the network bandwidth doubles, the demand for network expansion increases geometrically. By optimizing the current centralized deployment of S/PGW, using the content distribution network CDN (ContentDelivery Network) to sink the content source, reasonably plan the data flow direction, improve the transmission efficiency of the bearer network, and create an efficient and intensive large-bandwidth network, which is the supporting operation The foundation and key to successful business transformation. At present, all kinds of mobile network 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, Internet Protocol Television (IPTV) services, leased line services, virtual private network VPN (Virtual Private Network) 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 over Ethernet (IPoE (Internet Protocol over Ethernet) protocol to access the Internet through the BRAS. The dedicated line service uses static/dynamic routing protocols to access the Internet through the service router SR (Service Router). The VPN service adopts the L2/L3MPLS VPN (Layer2/Layer3 Multi-Protocol Label Switching Virtual Private Network) protocol through the business edge router PE networking. Mobile network data services converge to the core network S/PGW through the local integrated service optical transmission 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, mobile network services need to be backhauled to the provincial center S/PGW through a dedicated bearer network, and connected to the Internet via Gi routers . The existing S/PGW (mobile network data service gateway) adopts a centralized deployment method, resulting in mobile network data service bearer (as shown in Figure 2) spanning three networks (local UTN network, local bearer network, and backbone bearer network) , The transfer level reaches 7 to 10 levels. When the traffic doubles, the bandwidth expansion requirements of equipment boards increase by 14 to 20 times. With the rapid growth of mobile network traffic, the multi-layer 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 control and forwarding coupling 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 analyze each PPP message, that is, the control process participates in the forwarding of data packets. This type of strongly coupled access method cannot realize the separation of the control plane and the forwarding plane. The tight coupling of PPPoE forwarding and control makes it impossible for BNG to separate control and forwarding. The existing S/PGW (mobile network data business service gateway) and CDN content sources are deployed in a centralized manner across the province, placed in the provincial core computer room, and users access the transmission of large-bandwidth, low-latency services (such as games and high-definition video) Long distances, many forwarding hops, and packet loss and congestion during hot spots lead to extended access times, poor user experience, and high expansion costs.

In order to meet business needs such as ultra-low latency, low lag, and large traffic, the industry has proposed edge cloud solutions, but the existing network architecture does not support edge cloud mobility management, and there is no effective solution to access edge cloud mobility. . In the existing network architecture, the mobile network data service gateway S/PGW is deployed in the core cloud. When a mobile terminal moves from one edge cloud service area to another edge cloud service area, the business traffic is uniformly connected to the Internet from the core cloud. 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, resulting in the business application server being unable to locate the real-time network location of the mobile terminal, and unable to schedule the nearest edge cloud as a mobile The terminal provides services nearby, so it cannot provide the same quality of service experience and guarantee the continuity of service experience; because the edge cloud cannot provide continuous services for cross-regional mobile terminals, it limits the business application scope and deployment promotion of the edge cloud.

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

The data traffic of the mobile device 30 passes through the UTN access device 40 sequentially, and the UTN convergence device 50 is connected to the S/PGW-U201 to complete the transmission of the mobile service request after convergence, and then connected to the MSG-U202 for data forwarding; the mobile device 30 The control signaling passes through the UTN access device 40, the UTN convergence device 50 accesses the S/PGW-U201, and then is sent by the S/PGW-U201 to the S/PGW-C103, and is 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 capable of communication and network services.

The fixed network equipment 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, multiple MSG-U202s are set. The services used by the fixed network device 90 include one or more of the following: broadband services, IPTV services, private line services, and VPN services, where IPTV is Internet video, and VPN is a virtual private network. The fixed network device 90 can be connected through broadband remote access server BRAS (Broadband Remote Access Server), full-service router SR (Service Router), service provider edge router PE (Provider Edge), broadband network gateway control device BNG (Broadband Network Gateway), etc. Multiple devices are aggregated and accessed, unified as the MSG-U202 for access and bearer to the edge cloud service application device 203, which simplifies the structure and reduces the construction cost.

In order to reduce the hardware configuration requirements of the terminal, these calculation tasks need to be placed on the edge cloud, and the calculation results are stored in the edge cloud.
