Embodiment 2

[0102] Embodiment 2 As shown in Figure 7, the process is to implement the distribution and scheduling of media resources by extending the MRF function. Through the interaction between MRFCs in the network, the interaction of media resource information and status information is completed, and the entire network is obtained. resource information, so that the AS / S-CSCF can initiate a resource request to any MRFC in the network, and the MRFC will route the sent media resource request message to the appropriate MRFC according to the information obtained through the interaction. Executing different business logics in the AS can provide UE with rich services, including basic streaming media services and various value-added services combined with streaming media and personalized services. The session control, routing, and service of all these services The processing mechanisms of triggering, user authentication and management, billing, service quality assurance, and multicast control a...

Abstract

The system includes following parts: P-CSCF, S-CSCF, and I-CSCF in use for implementing controlling session, routing, and service triggering functions; entity for enabling stream media service (SMS) is in use for implementing supporting function needed by SMS; media resources functional (MRF) entity is in use for implementing function of media server; media resources locating function (MRLF) entity, or media resources broker function (MRBF) entity is in use for implementing function of distributing and dispatching media resource; application server AS is in use for implementing function of logic controlling SMS; user signed data service function (UPSF) is in use for saving user information of signed stream media user, authority information, and selectable SMS information; and user equipment UE. Comparing prior art, the invention realizes united authentication, charging, managing supporting functions for users, and guarantees QoS.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to an IMS-based streaming media network system. Background technique [0002] Streaming media service or IPTV (Internet Internet Television) service is a new service that has developed rapidly in recent years. The streaming media service uses streaming transmission technology to transmit multimedia files, including video, audio and other file content, on a packet-switched network. The key technology of streaming media is streaming transmission technology, its main feature is to put continuous video and audio information on the website server after processing, so that users can watch and listen while downloading, without waiting for the entire file to be downloaded to their own machines can be viewed later. [0003] However, there is no uniform standard for existing streaming media network and IPTV network solutions. A typical architecture is shown in Figure 1. The existing ...
