Abstract

The invention provides interconnection equipment of an internet protocol television (IPTV) system based on an IP multimedia subsystem (IMS) and methods for starting the same, requesting the broadcasting of programs and broadcasting programs lively. The interconnection equipment comprises a visit network and an affiliation network, wherein the visit network is used for accepting the visit of user equipment (UE) and comprises a transmission function entity, a user profile server function (UPSF) entity, a Core IMS and an internet border control function (IBCF) entity, and the affiliation network to which the UE is affiliated comprises a Core IMS, an application entity, an IPTV service control function entity, a transmission function entity, an IPTV media function (MF) entity and an IBCF entity. The invention realizes the roaming and the nomadism of the IPTV user in any region and improves the core competitiveness of an IPTV system.

Description

technical field [0001] The present invention relates to the field of communication, in particular to an interconnection device of an IMS-based IPTV system and methods for on-demand, on-demand and live broadcast. Background technique [0002] At present, the frame structure of the next generation communication network (Next Generation Network, NGN for short) has been basically determined. In addition to the management level, NGN also includes user level, transport level, business control level and application level. The IP Multimedia Subsystem (IMS, IPMultimedia Subsystem) is a collection of main functional entities in the service control plane. Registration, authentication, authentication, QoS (Quality of Service, Quality of Service) management and guarantee of users and terminal equipment can be realized through IMS; at the same time, IMS supports multiple user access technologies, user nomadic and mobility management, and other Traditional networks or next-generation net...
