Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
Fig. 1 is a schematic diagram of a conventional cloud service architecture, as shown in fig. 1, where the cloud service architecture is composed of a plurality of central cloud service ends deployed in a central cloud machine room and a cloud platform operating system, when resources are allocated to a remote user terminal, the usage situation of a resource pool of the entire cloud service architecture is often considered, for example, resource scheduling is performed based on factors such as resource occupation requests and processing speed of each central cloud service end, so that the central cloud service ends are allocated to the user terminal to provide corresponding data services.
Based on the traditional resource scheduling mode of the cloud service architecture, the network delay is higher, and the network delay cannot be suitable for the requirements of high-quality services, such as high-definition videos, cloud games and the like.
In order to improve the real-time performance of network services, a cloud service architecture based on edge computing is widely applied. Fig. 2 is a schematic structural diagram of a cloud service architecture provided by an embodiment of the present application, as shown in fig. 2, where the cloud service architecture includes a plurality of central cloud service ends and scheduling servers deployed in a central cloud machine room, and edge cloud service ends deployed in a plurality of edge cloud machine rooms, and each scheduling server schedules an edge cloud server to provide data service for a user terminal within a service range of the edge cloud server, so as to realize sinking of the central cloud service by using the edge cloud machine room, reduce network delay of a service, and improve cloud service quality.
In some embodiments, the edge cloud machine room may include a convergence layer edge machine room and a ground-level edge cloud machine room, and may also include a field-level edge cloud machine room.
In some embodiments, the edge cloud service may be a site-level, convergence layer, or ground-market-level edge cloud service.
In some embodiments, in a scenario facing the convergence layer edge room, the mobile upstream flows reach the UPF (User Plane Function ) network elements deployed in the convergence layer edge cloud room through MAR (Metro Access Router, metropolitan area network access device), MER (Metro Edge Router, metropolitan area network convergence device). In a scene facing to a city-level edge cloud machine room, the upstream flow of the mobile network reaches UPF (User Plane Function ) network elements deployed in the city-level edge cloud machine room through MAR, MER and MCR (metropolitan area network core equipment).
In some embodiments, the ground level edge cloud machine room or provincial core machine room is further deployed with an SMF (Session Management Function ) network element, and in fig. 2, the SMF is deployed in the ground level edge cloud machine room as an example.
In the mobile network service scheduling policy based on the cloud service architecture shown in fig. 2, the scheduling server generally performs resource scheduling based on the static address of the user terminal configured by the SMF network element, so that the service scheduling flexibility is poor, and the scheduling server is not suitable for the development of mobile network personal users or 2C services.
In order to improve the flexibility of resource scheduling of a cloud service mechanism based on edge cloud, the embodiment of the application provides an edge cloud service scheduling strategy taking a single mobile network user as granularity, which is executed by a scheduling system, an authentication server of the scheduling system determines an IP address of an LNS (L2 TP Network Server, two-layer tunneling protocol network server) corresponding to a user terminal, and then the LNS of the IP address dynamically allocates a source IP address to the user terminal based on a private IP address pool, so that the scheduling server allocates an edge cloud service end to a service access request of the user terminal based on the source IP address, thereby reducing network delay of a service and improving service quality.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 3 is a schematic structural diagram of a scheduling system according to an embodiment of the present application, where the scheduling system is applicable to the cloud service architecture in the embodiment shown in fig. 2, and as shown in fig. 3, the scheduling system includes an authentication server 310 and a scheduling server 320, where the authentication server 310 and the scheduling server 320 are both deployed in a central cloud room.
The authentication server 310 is configured to receive an authentication request of a user terminal, determine an IP address of a two-layer tunneling protocol network server LNS corresponding to the user terminal based on the authentication request, and add the IP address of the LNS corresponding to the user terminal to a response message of the authentication request, so that an LNS corresponding to the IP address of the LNS in the response message allocates a source IP address to the user terminal, so that the user terminal initiates a service access request based on the source IP address; the scheduling server 320 is configured to receive a service access request of the user terminal, and determine, based on a source IP address in the service access request, an IP address of an edge cloud server corresponding to the user terminal, so that the edge cloud server 330 corresponding to the user terminal responds to the service access request. The edge cloud service end 330 is deployed in each city-level edge cloud machine room.
In some embodiments, authentication server 310 is an AAA server and dispatch server 320 is an OTT server.
In some embodiments, after the user terminal is started up to log on or a location update occurs, if the location of the user terminal exceeds the service range or coverage area of the current edge cloud service end 330, when the user terminal initiates a service request, the edge cloud service end 330 is allocated to the service request of the user terminal based on the scheduling system provided in this embodiment.
Fig. 4 is a schematic structural diagram of a dispatching system provided in another embodiment of the present application, and referring to fig. 3 and fig. 4, the dispatching system includes a central cloud room, a plurality of city level edge cloud rooms and a convergence layer edge cloud room, where a UDM (Unified Data Management, unified data management function), a plurality of central cloud servers, an authentication server 310 and a dispatching server 320 are disposed in the central cloud room; SMF, MCR, UPF, LNS, CR (Core Router, metropolitan area network Core Router) and an edge cloud server 330 are deployed in the city level edge cloud machine room; MER, UPF, LNS and an edge cloud server 330 are deployed in the convergence layer edge cloud machine room.
In some embodiments, the authentication request for the user terminal is generated by the SMF based on a service request for the user terminal.
Specifically, when the user terminal initiates a service request, the SMF generates an authentication request for the user terminal according to subscription data of the user terminal stored in a UDM acquired in advance.
Specifically, after the mobile network user subscribes to the edge cloud acceleration service, the BSS (Business Support System, service support system) may configure subscription data, such as authentication parameters, for the mobile network user in the UDM, and may also configure an IP address of the LNS corresponding to the mobile network user in an authentication server, such as an AAA (Authentication, authorization, accounting, authentication, authorization, and accounting) server, by the BSS.
Further, the correspondence between the mobile subscriber and the AAA server used by the mobile subscriber may be established in the UDM according to the mobile subscriber's identification code, such as MSISDN (Mobile Subscriber ISDN ), IMSI (International Mobile Subscriber Identity, international mobile subscriber identity), SUPI (Subscription Permanent Identifier, subscriber permanent identity), etc., where the ISDN is an integrated services digital network (Integrated Services Digital Network), i.e. the IP address of the AAA server corresponding to the mobile subscriber is found based on the identification code.
In some embodiments, the service request includes an identification code of the mobile network user corresponding to the user terminal.
Specifically, the SMF may search for subscription data of the corresponding mobile network user based on the identifier code in the service request sent by the user terminal and the identifier code acquired in advance from the UDM, and if the IP address of the AAA server corresponding to the identifier code is searched, send an authentication request to the AAA server.
Further, if the IP address of the AAA server corresponding to the identifier code is not retrieved, for example, the mobile network user does not subscribe to the edge cloud acceleration service, the SMF does not send an authentication request, and allocates a source IP address, i.e., the IP address of the user terminal, to the mobile terminal of the mobile network user in its own IP address pool, where the user can access the service end of the central cloud through the source IP address.
Specifically, after the SMF obtains the subscription data corresponding to the user terminal or the mobile network user, when the user initiates a service request, a flow of authentication to the authentication server 310 is triggered based on the subscription data.
In some embodiments, the authentication request is a Radius (Remote Authentication Dial In User Service, remote authentication dial-in user service) authentication request. The SMF generates a Radius authentication request based on the subscription data of the user terminal and triggers the Radius authentication request flow.
Specifically, after the authentication server 310 receives the authentication request of the user terminal sent by the SMF, the Radius authentication request flow is triggered, and the authentication server 310 determines the IP address of the LNS corresponding to the user terminal based on the identification code of the user terminal.
Further, the IP address of the LNS corresponding to the user terminal of the mobile network user may be determined based on the correspondence between the identification code of the mobile network user and the IP address of the LNS stored in the authentication server 310.
Further, the IP address of the LNS corresponding to the user terminal may be determined based on the identification code of the mobile network user in the service request and the IP address of the LAC (L2 TP Access Concentrator, two-layer tunneling protocol access concentrator) where the user terminal is located. The LAC device where the user terminal is located may be an SMF or a UPF corresponding to the user terminal. Or, the IP address of the LNS corresponding to the user terminal may be determined based on the identification Code of the mobile network user in the service request and the TAC Code (Track Area Code) where the user terminal is located.
Optionally, the authentication server 310 is specifically configured to: and determining the IP address of the LNS corresponding to the user terminal according to the identification code in the authentication request of the user terminal.
Optionally, the authentication server 310 is specifically configured to: acquiring a first pre-established corresponding relation, wherein the first corresponding relation is used for describing the corresponding relation between the identification code and the IP address of the LNS; and determining the IP address of the LNS corresponding to the user terminal according to the first corresponding relation and the identification code in the authentication request of the user terminal.
In some embodiments, the first correspondence may be modified based on requirements, that is, the IP address of the LNS corresponding to the identification code of the mobile network user may be adjusted, so as to implement fine and flexible configuration of resources, implement flexible switching between different edge cloud service ends 330 by the user terminal, and guide the traffic of the user to different edge clouds.
And mapping the mobile network user and the LNS address through a first pre-established corresponding relation, so that the response speed of address configuration is improved.
Specifically, after determining the IP address of the LNS corresponding to the user terminal, the authentication server 310 adds the IP address of the LNS to the response message of the Radius authentication request of the user terminal, so that the LNS corresponding to the IP address of the LNS in the response message allocates a source IP address to the user terminal.
Specifically, the SMF/UPF is taken as LAC, the router is taken as LNS, an L2TP VPN (Virtual Private Networks, virtual private network) tunnel is established between the UPF and the router, a private network IP address pool is independently planned and configured by the LNS corresponding to the IP address of the LNS in the response message, and a source IP address is distributed for a mobile network user or a user terminal based on the private network IP address pool.
Specifically, an L2TP VPN tunnel may be established between the UPF and the router based on the IP address of the LAC where the user terminal is located and the mapping relationship between the IP address of the LAC and the IP address of the LNS stored in the authentication server, or the TAC code where the user terminal is located and the mapping relationship between the TAC code stored in the authentication server and the IP address of the LNS.
In some embodiments, in the first correspondence, the IP address of the SMF/UPF corresponds one-to-one with the IP address of the LNS, or the TAC code corresponds one-to-one with the IP address of the LNS.
In some embodiments, the IP address of one SMF/UPF may correspond to the IP addresses of multiple LNS's, or one TAC encoding may correspond to the IP addresses of multiple LNS's. Thereby realizing that the LAC can establish the L2TP VPN tunnel with a plurality of different LNS devices at the same time.
Specifically, the LNS maps the IP address in the private network IP address pool to an IP address in a specified public network IP address field through NAT ((Network Address Translation, network address translation), and determines a source IP address of the user terminal based on the mapped IP address in the public network IP address field, so that the user terminal can access the corresponding scheduling server through the IP address in the public network IP address field.
Optionally, the authentication server 310 is specifically configured to:
determining a user tag corresponding to the user terminal according to the identification code in the authentication request of the user terminal; if the user label corresponding to the user terminal is a preset label, determining the IP address of the LNS corresponding to the user terminal according to the authentication request of the user terminal.
The preset label is a label of a user subscribed to the edge cloud acceleration service.
Specifically, based on the identification code in the authentication request of the user terminal, configuration information corresponding to the identification code stored in the authentication server 310 may be obtained, so as to determine whether a user tag corresponding to the user terminal is preset based on the configuration information; if yes, determining the IP address of the LNS corresponding to the user terminal according to the authentication request of the user terminal, and adding the IP address of the LNS corresponding to the user terminal into a response message of the authentication request of the user terminal so as to carry out a subsequent flow based on the response message; if not, directly generating a response message of the authentication request of the user terminal without determining the IP address of the LNS corresponding to the user terminal, wherein the response message does not contain the IP address of the LNS so as to carry out subsequent flow based on the response message.
After determining the source IP address of the user terminal, the user terminal sends a service access request to the scheduling server 320, where the scheduling server allocates an edge cloud server 330 with a matching address to the user terminal based on the source IP address in the service access request (i.e., the IP address in the private network IP address pool allocated by the LNS to the user terminal, and maps the IP address to the IP address in the specified public network IP address segment through NAT), that is, determines the IP address of the edge cloud server 330 corresponding to the user terminal, so that the edge cloud server 330 corresponding to the user terminal responds to the service access request.
The identities of the mobile network users are distinguished through the setting of the preset labels, so that the flexibility of resource scheduling is improved.
Specifically, the scheduling server 320 determines that, in the service area, the edge cloud service end 330 corresponding to the source IP address in the service access request of the user terminal is a service end of the user terminal, and the corresponding edge cloud service end 330 provides the data access service for the user terminal.
Optionally, the scheduling server 320 is specifically configured to:
acquiring service IP address segments corresponding to the edge cloud service ends 330; determining a service IP address segment to which the source IP address belongs according to the source IP address in the service access request; and determining an edge cloud server corresponding to the service IP address segment to which the source IP address belongs, and performing an edge cloud server 330 corresponding to the service access for the user terminal.
For example, for a service access request of which the source IP address belongs to an IP address pool of a mobile network user specified in an edge cloud a coverage area, returning to an IP address of an edge cloud server a as a destination address for access by the mobile network user, where the edge cloud server a is an edge cloud server dedicated to serving the mobile network user in the edge cloud a service area and is deployed in an edge cloud a machine room; and returning the IP address of the edge cloud server B to a service access request of an IP address pool of the mobile network user, which belongs to the specified coverage area of the edge cloud B, wherein the IP address of the edge cloud server B is a destination address accessed by the mobile network user, and the edge cloud server B is an edge cloud server which is specially used for serving the mobile network user in the service area of the edge cloud B and is deployed in a machine room of the edge cloud B.
Network service of the user terminal in the corresponding area is performed through the plurality of edge cloud service ends 330 with different coverage areas, so that network delay is reduced, and service quality is improved.
The scheduling system provided by the embodiment is aimed at an application scenario of an operator responding to a service request of a mobile network user, an authentication server in the scheduling system responds to the authentication request of a user terminal, so that an IP address of an LNS (network node) corresponding to the user terminal is determined, and then the LNS corresponding to the user terminal distributes an IP address, namely a source IP address, to the user terminal, so that the user terminal initiates the service access request based on the source IP address, and the scheduling server dispatches an edge cloud server with the matched IP address to respond to the service access request based on the source IP address in the service access request, thereby realizing a resource scheduling method with a single mobile network user as granularity, having low scheduling cost and high speed, combining the configuration of a service IP address field corresponding to the edge cloud server, realizing a resource scheduling strategy flexibly deployed in a wide area range as required, and being applicable to service scenarios of 2B (to government and vertical industry clients) and 2C; meanwhile, network acceleration is performed based on the edge cloud server, so that network delay is reduced, and user satisfaction is improved.
