Problems solved by technology

In 4G network deployment, because PGW (PDN Gateway, public data network gateway) is deployed in a centralized manner at the provincial level, MEC cannot be deployed close to users, so it is difficult to implement CDN services based on mobile networks

Embodiment Construction

[0033] The technical solution of the present disclosure will be described in further detail below with reference to the drawings and embodiments.

[0034] The inventors found that in related technologies, the terminal initiates a DNS request to obtain the access address of the dispatching system of the application, and then the terminal sends a request message to the dispatching system of the application according to the obtained access address, and the request will carry business domain name information; the dispatching system of the application The system will match the user location information according to the source IP address information of the message, and feed back the access address of the nearest CDN AS (Application Server, application server) to the terminal, and the terminal can access the application service according to the access address.

[0035] However, in the 5G scenario, the user initially accesses the network from the central UPF, which makes the applicatio...

Abstract

The invention provides a business scheduling method and system, a storage medium and a business service system, and relates to the technical field of mobile edge computing. The service scheduling method disclosed by the invention comprises the following steps: a central user plane function UPF acquires access address information of a service according to a DNS response sent by a central domain name system DNS to a user terminal; a terminal private network address, wireless position information, slice information and access address information are inserted into the received HTTP DNS request, and the processed HTTP DNS request is sent to a 5G core network proxy 5GC Proxy; the 5GC Proxy replaces the wireless position information in the HTTP DNS request with a mobile edge computing MEC identifier of a corresponding geographic position, and forwards the mobile edge computing MEC identifier to an HTTP DNS server corresponding to the access address information; and the 5GC Proxy receives the HTTP DNS response fed back by the HTTP DNS server, and forwards the HTTP DNS response to the user terminal after initiating UPF / ULCL insertion to a policy control function (PCF) entity, thereby realizing local flow distribution, reducing the network flow burden and improving the user access speed.

Description

technical field [0001] The present disclosure relates to the technical field of mobile edge computing, in particular to a business scheduling method, system, storage medium and business service system. Background technique [0002] In the CDN (Content Delivery Network, content distribution network) architecture, the server accessed by the user will be allocated nearby, so as to achieve the effect of increasing the user access speed and reducing the network burden. In 4G network deployment, since PGW (PDN Gateway, public data network gateway) adopts a provincial-level centralized deployment method, MEC cannot be deployed close to users, so it is difficult to implement CDN services based on mobile networks. Contents of the invention [0003] The inventors found that in 5G SA (Standalone, independent networking) network, UPF (User Plane Function, user plane function) can be deployed downward on demand, making it possible to deploy low-latency and high-bandwidth CDN services b...
