Abstract

The present invention provides a method and device for providing content during switching. The present invention relates to a method and apparatus for providing mobile content to seamlessly deliver content to a mobile node through local caching devices distributed in a mobile network even during handover of the mobile node. When the specific local cache device detects the handover of the mobile node, the mobile CDN controller distributes the content data transmitted from the specific local cache device to the mobile node, or unblocks the content from the source server to transfer the content data from the source server to the mobile node. The content data of the server is distributed to the mobile node after handover.

Description

technical field [0001] The present invention relates to a mobile content providing method and apparatus for providing content to a mobile node connected to a mobile network, and more particularly, to an A method and device for providing mobile content. Background technique [0002] The content distribution network (CDN) service will stably distribute various types of content including movies, music videos, etc. to users, and realize the CDN service by pre-stored content in multiple cache servers distributed in the general network, through such as The load balancer of the GLB (Global Load Balancing) server selects the most suitable cache server from among multiple cache servers, and distributes the requested content to the user terminal through the selected cache server. [0003] This kind of CDN is based on the Internet, and overcomes the instability in the Internet such as data loss, bottlenecks, transmission rate drops, and inconsistent data transmission. [0004] On the...
