All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
In the 4G era, high-definition video, online games and other applications put forward high requirements on network delay, and with the arrival of the 5G era, emerging industries such as telemedicine, VR/AR and the like and emerging services put forward almost rigorous requirements on network delay, and low-delay networks have become development directions concerned by operators. With the rapid growth of 4G users and traffic, the currently centrally deployed S/PGW and multi-layer network architecture of the bearer network cannot meet the large bandwidth requirement of the users. The network bandwidth is doubled, and the network capacity expansion requirement is increased in geometric grade. By optimizing the currently and centrally deployed S/PGW, a Content Delivery Network (CDN) (content delivery network) is used for sinking a content source, the data flow direction is reasonably planned, the transmission efficiency of a bearer network is improved, and an efficient and intensive large-bandwidth network is created, which is the basis and key for supporting the successful transformation of an operator. At present, control and bearing of various network moving and fixed network services are realized through independent networks, and unified integration and scheduling of resources cannot be realized through construction, management and maintenance, so that the investment efficiency is low and the maintenance cost is high.
As shown in fig. 1, the main services of the existing network include broadband service, interactive network television iptv (internet protocol television) service, Private line service, virtual Private network vpn (virtual Private network) service, and mobile network data service. The broadband service adopts a point-To-point communication protocol PPPoE (Point-To-Point protocol Over Ethernet) protocol of the Ethernet To access the Internet through a broadband Remote access server BRAS (broadband Remote Access Server). The IPTV service adopts an IP Protocol IPoE (Internet Protocol over Ethernet) Protocol on Ethernet to access the Internet through BRAS. The private line service adopts a static/dynamic routing protocol to access the Internet through a service router SR (service router). The VPN service adopts a two-Layer/three-Layer Multi-Protocol Label Switching Virtual private network L2/L3MPLS VPN (Layer2/Layer3 Multi-Protocol Label Switching Virtual private network) Protocol to be networked through a service edge router PE. The Network-moving data service is converged and converged to a core Network S/PGW through three networks of a local integrated service optical transmission Network UTN (Universal Transport Network Over fiber), a local bearer Network and a backbone bearer Network, and then is accessed to the Internet through a router. The existing network architecture has the following problems: the network moving service and the fixed network service are controlled and loaded by adopting independent networks, the network moving service needs to be transmitted back to the provincial center S/PGW through a special load-bearing network, and the network moving service is accessed to the Internet through a Gi router. The existing S/PGW (mobile network data service gateway) adopts a centralized deployment manner, which results in that the mobile network data service bearer (as shown in fig. 2) spans three networks (a local UTN network, a local bearer network, and a backbone bearer network), and the transit level reaches 7 to 10 levels. The flow is doubled, and the bandwidth expansion requirement of the equipment board card is increased by 14 to 20 times. With the rapid increase of the network moving flow, the multi-layer network architecture of the existing bearer network cannot efficiently support the service requirement. The existing fixed network has different access, authentication and forwarding modes of various services, especially different degrees of tightness of control and forwarding coupling of different services. The broadband service is based on PPPoE, and because two layers of PPP (Point to Point protocol) and PPPoE are adopted for encapsulation when the data packet is forwarded, each PPP message needs to be analyzed in the control process, namely the control process participates in the forwarding of the data packet. Such strongly coupled access methods cannot achieve separation of the control plane and the forwarding plane. The PPPoE forwarding and control tightly coupled feature results in the inability of the BNG to achieve control and forwarding separation. Existing S/PGW (mobile network data service gateway) and CDN content sources both adopt a provincial centralized deployment manner, and are placed in a provincial core computer room, so that users access large bandwidth, low-delay services (such as games and high-definition videos) have long transmission distance, many forwarding hops, and packet loss and congestion in hot spots, thereby resulting in prolonged access time, poor user experience, and high capacity expansion cost.
In order to solve the service requirements of ultra-low time delay, low blocking, large flow and the like, an edge cloud solution is proposed in the industry, but the existing network architecture does not support the mobility management of the edge cloud, and an effective solution is not provided for the problem of accessing the mobility of the edge cloud. In the existing network architecture, a mobile network data service gateway S/PGW is deployed in a core cloud, when a mobile terminal moves from one edge cloud service area to another edge cloud service area, since service traffic uniformly accesses the internet from the core cloud to access a service application, a service application server needs to know a network location mapping relationship between the mobile terminal and the edge cloud, and the mapping relationship information cannot be directly obtained, the service application server cannot locate a real-time network location of the mobile terminal, cannot schedule the edge cloud closest to the location to provide a service for the mobile terminal nearby, and thus cannot provide service experience with the same quality and guarantee continuity of the service experience; because the edge cloud cannot provide continuous service for the cross-regional mobile terminal, the service application range and deployment and popularization of the edge cloud are limited.
Based on the foregoing 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, where the edge cloud mobility management system TX includes: the system comprises a core cloud platform 10, an edge cloud platform 20, a network moving device 30, a UTN access device 40, a UTN aggregation device 50, a switch sw (switch)60, a core router cr (core router)70, an Internet device (Internet)80 and a fixed network device 90. The core cloud platform 10 includes a core Control device 101, a Multi-Service Gateway Control plane MSG-C (Multi-Service Gateway-Control)102, and a mobile network data Service Gateway Control plane S/PGW-C (Serving/Packet Gateway-Control)103, and the edge cloud platform 20 includes an S/PGW-U201, an MSG-U202, and an edge cloud Service application device 203. The services used by the fixed network device 90 include one or more of the following: broadband service, IPTV service, private line service, VPN service.
Service access requests of the mobile equipment 30 sequentially pass through the UTN access equipment 40, the UTN convergence equipment 50 converges and then accesses the S/PGW-U201 to complete transmission of the service access requests, the service access requests are accessed into the MSG-U202 to be forwarded to the edge cloud service application equipment 203, and the edge cloud service application equipment 203 sends the mapping relation between the edge cloud service application equipment 203 and the mobile equipment 30 to the core control equipment 101. The data traffic of the mobile device 30 passes through the UTN access device 40 in sequence, and the UTN convergence device 50 converges and then accesses the S/PGW-U201 to complete the transmission of the mobile service request, and accesses the MSG-U202 to perform data forwarding; the control signaling of the mobile device 30 passes through the UTN access device 40, the UTN convergence device 50 accesses the S/PGW-U201, and then the S/PGW-U201 sends the control signaling to the S/PGW-C103, and the S/PGW-C103 cooperates with the S/PGW-U201 to complete the access control and resource management of the mobile service; the mobile device 30 may be a mobile device such as a mobile phone, a notebook or a tablet pc, which has communication and network services.
The fixed network equipment 90 is accessed to the MSG-U202 through the SW60 for data forwarding, and then is accessed to the Internet through the MSG-U202. In this embodiment, a plurality of MSG-us 202 are provided. The services used by the fixed network device 90 include one or more of the following: broadband service, IPTV service, private line service, VPN service, wherein IPTV is an Internet video, and VPN is a virtual private network. The fixed Network device 90 may converge and Access through a plurality of devices such as 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), and the like, and unify to Access and carry the MSG-U202 to the edge cloud service application device 203, thereby simplifying the structure and reducing the construction cost.
Referring to fig. 4, an embodiment of the present invention provides a method for edge cloud mobility management, where the method includes:
401. the first edge cloud service application device receives a service access request sent by a terminal.
The service access request is used for requesting a first edge cloud service application device to provide service of service application for the terminal, and the service access request carries first real-time state information, wherein the first real-time state information comprises: mapping relation between the identifier of the terminal and the identifier of the second edge cloud service application equipment; the second edge cloud service application device provides service application service for the terminal before the first edge cloud service application device.
402. The first edge cloud service application device sends a service switching request to the core control device according to the mapping relation between the service access request, the identifier of the terminal and the identifier of the second edge cloud service application device, and receives a service switching instruction sent by the core control device.
The service switching request comprises a mapping relation between the identifier of the terminal and the identifier of the second edge cloud service application equipment; the core control device verifies the validity of the terminal according to the mapping relation between the identifier of the terminal and the identifier of the second edge cloud service application device, and generates a service switching instruction after the verification is passed.
Specifically, the core control device compares the mapping relationship between the identifier of the terminal sent by the first edge cloud service application device and the identifier of the second edge cloud service application device with the mapping relationship between the locally stored identifier of the terminal and the identifier of the edge cloud service application device, if the mapping relationship is consistent, the mapping relationship is proved to be legal, otherwise, the mapping relationship is not legal.
In addition, before step 402, the method further comprises:
s1, the first edge cloud service application equipment receives the traffic of the service application sent by the mobile network data service gateway user plane S/PGW-U through the multi-service gateway user plane MSG-U; the system comprises an S/PGW-U, an MSG-U, a mobile network service client, a fixed network service client, an S/PGW-U, MSG-U and a first edge cloud service application device, wherein the S/PGW-U is used for being responsible for forwarding of a mobile service data plane and achieving local traffic offload, the MSG-U is used for being used as an access device for traffic forwarding for the mobile network service client and the fixed network service client, and the S/PGW-U, MSG-U and the first edge cloud service.
403. And the first edge cloud service application equipment provides service application service for the terminal according to the service switching indication.
Specifically, the first edge cloud service application device obtains a second progress of the second edge cloud service application device according to the service switching indication, and provides service application service for the terminal according to the first progress and the second progress; the first real-time state information further comprises a first progress of the business application, and the first progress is progress information generated on the terminal when the second edge cloud business application equipment provides the business application service for the terminal; the second schedule includes schedule information generated on the second edge cloud service application device when the second edge cloud service application device provides the service of the service application for the terminal.
Illustratively, the first schedule may be a playing schedule of the service application on the terminal, for example, a schedule of video playing, such as how many minutes and how many seconds a certain tv series is played to the episode. The second progress may be a playing progress of the service application on the second edge cloud service application device, for example, a progress of video playing, such as how many minutes and how many seconds a certain tv series is played to the episode.
Illustratively, the second schedule may further include intermediate process calculation result information. For example: in a scene of business application such as cloud games, background rendering (such as sound and image processing) of the cloud games needs to be performed with higher image resolution and high-fidelity sound effect and 3D image effect in order to achieve a cool effect, the computing amount is huge, stronger computing and storage capacity is needed, computing tasks need to be placed in an edge cloud in order to reduce the hardware configuration requirement on a terminal, computing results are stored in the edge cloud, and a mobile phone terminal is responsible for inputting and outputting game actions and playing and presenting the game background rendering results without storing the computing result data of the game background rendering.
404. The first edge cloud service application equipment sends the second real-time state information to the core control equipment, so that the core control equipment synchronizes the second real-time state information to the local; the second real-time state information comprises a mapping relation between the identifier of the terminal and the identifier of the first edge cloud service application device.
In addition, considering the handling of a special case when the terminal is frequently switched between the boundary service areas of the first edge cloud service application device and the second edge cloud service application device (e.g. affected by a wireless environment), in order to reduce frequent message interaction caused by the frequent message interaction, the first edge cloud service application device and the second edge cloud service application device are set for a period of time, and meanwhile, status information of a service application run by the terminal is retained and maintained, and a related edge cloud mobility management process is as follows: after the terminal is switched from the second edge cloud service application device to the first edge cloud service application device, the terminal is quickly switched back to the second edge cloud service application device under the influence of a boundary wireless environment, after the second edge cloud service application device receives a service access request of the terminal, the second edge cloud service application device judges that the terminal is frequently switched at the boundary according to timestamp information of the service access request, at the moment, the second edge cloud service application device forwards the service access request of the terminal to the first edge cloud service application device, and the first edge cloud service application device still provides service application services for the terminal.
