Abstract

The invention discloses a content-delivery device for realizing a content-delivery function in the next generation network. The content-delivery device is in a service layer over the transmission layer and is connected with a service control function entity and a transmission function entity for delivering the application function module content from the next generation network to terminal users. Otherwise, the invention also discloses a content demanding method, a content delivering method and a network structure of the next generation network. By adopting the invention, various multimedia service systems such as IPTV and the like can be compatible with the next generation network, therefore, it is convenient for the development of various services of the next generation network, and corresponding technology gaps can be filled.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a content delivery device, a content on-demand method, and a content delivery system for next-generation networks. Background technique [0002] At present, the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) has basically determined the research framework structure for the first phase of the next generation communication network (NGN). In addition to the management level, NGN also includes user level, transport level, business control level and application level. [0003] Moreover, the IP Multimedia Subsystem (IMS) is a collection of main functional entities in the service control plane. Registration, authentication, authentication, QoS management and assurance of users and terminal equipment can be realized through IMS; at the same time, IMS supports multiple user access technologies, supports user nomadic and mobility managemen...
