Problems solved by technology

However, as more and more users are used to watching services such as online video through a variety of mobile terminals, a mobile edge computing (Mobile Edge Computing, MEC) network architecture is proposed. In this MEC network architecture, CDN deployment Each node of the network sinks to the edge of the MEC network architecture, such as the access network side. Since the terminal device accesses the CDN through the same anchor user plane device, when the terminal device moves between different MECs, the IP address remains unchanged, and the CDN The routing node cannot assign the nearest CDN service node to the terminal device

Embodiment Construction

[0052] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0053] Embodiments of the present application provide an address allocation method and related equipment. When a terminal device moves between different mobile edge computing centers, the IP address can be allocated according to the user plane gateway device connected to the terminal device, so that the CDN routing node remains the same. The nearest CDN service node can be selected for the terminal device according to the IP address of the terminal device.

[0054] In order to facilitate the understanding of the embodiments of the present application, firstly, a brief description of the network architecture applicable to the current CDN is given. At present, CDN routing nodes and CDN service nodes in CDN technology are generally deployed at relatively high positions, that is, close...

Abstract

The invention provides an address allocation method and device, and the method comprises the steps that network control equipment determines the equipment identifier of user plane gateway equipment accessed by terminal equipment; the network control equipment configures an internet protocol IP address of the terminal equipment according to a first mapping relation and the equipment identifier, andthe first mapping relation is a corresponding relation between the equipment identifier of each user plane gateway equipment and each IP address field; and the network control equipment informs the terminal equipment of the IP address. Therefore, according to the method, the corresponding IP address can be distributed according to the user plane gateway device accessed by the terminal device, andthe problem that the IP address of the terminal device is not changed in the moving process is solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an address allocation method and device. Background technique [0002] Currently, content delivery network (Content Delivery Network, CDN) technology can enable users to visit nearby content delivery network nodes to obtain desired content, thereby alleviating Internet network congestion. Among them, the business scenarios of content delivery network mainly involve file download, web page access, application acceleration, streaming media playback, etc. The nodes deployed by the CDN are located close to the entrance of the Internet. For example, each node of the CDN is deployed behind the firewall, such as behind the routing conversion server. In this way, the routing conversion server assigns different IP addresses to terminal devices in different regions. Therefore, the CDN The routing node may select the nearest CDN service node for the terminal device acc...
