Problems solved by technology

[0007] The disadvantage of the IMS architecture is that it does not provide the implementation of IPTV services in fixed or mobile networks
Although the mechanisms provided in IMS define the general procedures for multimedia services, they do not define how to integrate IPTV services
Specifically, in the current version of the standard, there is no provision for recovery of service plans, i.e. channels subscribed by users and corresponding IP addresses

Embodiment Construction

[0068] figure 1 Shown is a system for activating IPTV services on an IP transport network 1, when a user of a terminal 10 has previously subscribed to one or more television channels provided by an operator or an associated third-party provider, the terminal 10 can The media stream provided by the TV source 20 is received via the IP transmission network 1 .

[0069] Terminal 10 is a fixed or mobile terminal and comprises means for reproducing audiovisual content and SIP signaling means. In the context of the present invention, terminal 10 may be a prior art audiovisual terminal such as a television set plus a SIP client, for example, the two elements may be physically separated or integrated in the same unit. In this way, the terminal 10 may be a mobile phone with a screen, or integrate a set-top box and a display screen or the like.

[0070] Such as figure 1 As shown, in the IMS architecture network 2, the IPTV service is activated from the terminal 10, and the IMS archite...

Abstract

The invention relates to a system for activating a television over IP (IPTV) service in an IMS architecture network (2) from a terminal (10) of a user subscribing to a television channel provided by said service. According to the invention, the system includes, in the IMS architecture network (2), an IPTV server (23) containing subscription information associating the user with the channel and information about the reception capacity required for the channel, and the terminal (10) includes means for sending the server (23) a message requesting activation of the television service and containing reception capacity information provided by the terminal (10). The server (23) can check the compatibility between the reception capacity information received from the terminal (10) and the reception capacity information required for the channel, and if compatibility is confirmed, send the terminal (10) a message in response to the activation request message, said response message containing an IP address of the channel. The invention can be applied to IP networks enabling audiovisual data to be broadcast in the IMS.

Description

technical field [0001] The present invention relates to a technique for activating services in an IP (Internet Protocol) network with an IMS (IP Multimedia Subsystem) architecture from a terminal of a user logged into the network. [0002] The invention finds particularly advantageous application in IP networks broadcasting audiovisual data in the IP Multimedia Subsystem defined by the 3GPP (Third Generation Partnership Project) and TISPAN (Telecommunications and Internet Integration Services and Protocols for Advanced Networking) standardization organizations . Background technique [0003] The IMS network architecture was introduced by 3GPP for mobile networks and then adopted by TISPAN for fixed networks. It provides dynamic setup and monitoring of multimedia sessions between two clients, and reservation of resources at media streaming network level. It also manages the interaction of services. [0004] Currently, IMS provides access to telephone, videophone, presence ...
