Push service negotiation method and device, and push service system

Abstract

The embodiment of the invention discloses a push service negotiation method, which is applied to an IMS Based IPTV network. The method comprises the following steps: receiving push service informationcarrying a push service identifier; analyzing the push service information; triggering push service logic according to the push service information, and sending a push service request carrying a pushcontent identifier; and negotiating to complete the push service logic. Simultaneously, the embodiment of the invention also discloses a push service negotiation device and a push service system. Thepush service negotiation method, the push service negotiation device and the push service system trigger the push service logic through the push service identifier and the push service information tonegotiate to complete the push service logic, can meet the requirement of pushing content to users by initiating session through a network side, can realize the push function universal for services to continue various push services, and can effectively improve application deployment and simplify the network complexity.

Description

technical field [0001] The invention relates to the field of network service push, in particular to a service push negotiation method and device, and a push service system. Background technique [0002] Internet Protocol Television (IPTV) provides IPTV services through the IMS network based on the multimedia subsystem (IPMultimedia Subsystem, IMS), so as to make full use of the existing registration, authentication, routing, session control and establishment, service triggering, Mechanisms such as billing and end-to-end Quality of Service (QoS) guarantees are used to provide users with streaming media services and multimedia services that integrate streaming media and real-time session services. [0003] At present, standard organizations such as TISPAN have formulated IPTV based on IMS (IMS Based IPTV) network-related standards. Service / content providers can provide users with live broadcast (Broadcast, BC) and content on demand (Content on Demand, CoD) through the IMS Base...

Problems solved by technology

[0007] However, in the existing technology, in addition to these basic services, there are also some enhanced IPTV services that need to actively initiate sessions on the network side to push content to users. For example, users can pre-register services in the network. Switch the program that the user is watching to this channel; or the user registers the type of program he is interested in with the network, and when there is a relevant program deployed in the network, the network side actively pushes the content to the user terminal, and there are other possibilities requirements, all require the network to actively push some content to users, but the current network does not provide a solution
