example 1

[0049] Figure 8 It shows a schematic diagram (roaming) of the interconnection between the IPTV network of NGN-BASED and the IPTV network (with SCF) of Non-NGN-BASED. Such as Figure 8 As shown, when two kinds of network interconnection need to exchange resources and admission control information, in the Non-NGN-BASED IPTV network with SCF, the resource control function (Resource Control, RC) is controlled through SCF, in NGN- In the BASED IPTV network, the SCF controls resources and admission control functions (Resource & Admission control function, RACF), and the ISCFs in the two network SCFs use control or session protocol (C / S Protocol) to complete the two networks Exchange of resource control information.

[0050] In this way, in the case that the network architecture of the Non-NGN-BASED IPTV network includes SCF, the above method further includes the following processing: In the network architecture of the Non-NGN-BASED IPTV network, the SCF (denoted as the first SCF) cont...

[0052] Picture 9 It shows a schematic diagram (roaming) of the interconnection between the NGN-BASED IPTV network and the Non-NGN-BASED IPTV network (without SCF). Such as Picture 9 As shown, when two kinds of network interconnection need to exchange resources and admission control information, through Non-NGN-BASED RC and NGN-BASED IPTV network RACF (resource and admission control subsystem) interactive transmission resource control Interactive information.

[0053] In this way, when the network architecture of the Non-NGN-BASED IPTV network does not include SCF, the above method further includes the following processing: RC and NGN-BASED IPTV network in the network architecture of the Non-NGN-BASED IPTV network The interaction of RACF of the network architecture realizes the resource control information interaction of the two networks.

[0055] Picture 10 It shows a schematic diagram of the interconnection between the Non-NGN-BASED IPTV network and the NGN third-party service provider.

[0056] From Picture 10 It can be seen that the ISCFs in the two network SCFs complete the resource control information exchange of the two networks through the control or the session protocol (C / S Protocol).

[0057] In this way, in the case that the Non-NGN-BASED IPTV network and the NGN third-party service provider are interconnected, the above method further includes the following processing: In the network architecture of the Non-NGN-BASED IPTV network, through the SCF ( In the network architecture of the NGN-BASED IPTV network, the SCF (denoted as the second SCF) controls the RACF; the IPTV service control function entity (ISCF) of the first SCF and the second SCF ) Through the control or session protocol to achieve the resource control information exchange of the two networks.

Abstract

The invention provides an IPTV network interconnection architecture and an interconnection method thereof, which are used for the interconnection of IPTV networks with different service patterns. The IPTV network interconnection architecture comprises a terminal user functional entity, an application functional entity, a content transmission functional entity, and a network functional entity or a transmission functional entity. The network functional entity or the network functional entity further comprises boundary functional entities which are connected with a core transmission functional entity in the network functional entity or the network functional entity, and when the IPTV networks with different service patterns are interconnected, the transmission layer interconnection is realized through the interconnection of the boundary functional entities.

Description

Technical field [0001] The present invention relates to IPTV networks, in particular, to IPTV network interconnection architecture and interconnection methods. It is mainly aimed at the interconnection of Non-NGN-Based IPTV networks and NGN-Based IPTV networks, including roaming conditions and third-party providers Interconnection situation. Background technique [0002] IPTV stands for interactive network television. It is a brand-new technology that uses broadband cable television networks to integrate multiple technologies such as the Internet, multimedia, and communications to provide home users with multiple interactive services including digital television. [0003] Generally, users can enjoy IPTV services in two ways at home: (1) computer, (2) network set-top box + ordinary TV. One of the characteristics of IPTV is to use the infrastructure of a broadband cable TV network, with home TVs as the main terminal electrical appliances, and provide multiple digital media services...
