example 1

[0049] Fig. 8 shows a schematic diagram of interconnection between the NGN-BASED IPTV network and the Non-NGN-BASED IPTV network (with SCF) (roaming). As shown in Figure 8, when two types 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 by the SCF, In the NGN-BASED IPTV network, the resource and admission control function (Resource&Admission control function, RACF) is controlled by the SCF, and the ISCFs in the two network SCFs use the control or session protocol (C / S Protocol) to complete the two Network resources control information exchange.

[0050] Like this, under the situation that the network architecture of the IPTV network of Non-NGN-BASED comprises SCF, above-mentioned method further comprises the following processing: in the network architecture of the IPTV network of Non-NGN-BASED, through SCF wherein SCF) controls...

example 2

[0052] Fig. 9 shows a schematic diagram (roaming) of the interconnection between the NGN-BASED IPTV network and the Non-NGN-BASED IPTV network (without SCF). As shown in Figure 9, when the two types of network interconnection need to exchange resources and admission control information, the interaction between the RC of the Non-NGN-BASED and the RACF (resource and admission control subsystem) of the NGN-BASED IPTV network Interaction information for transport resource control.

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

example 3

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

[0056] It can be seen from FIG. 10 that the resource control information exchange of the two networks is completed through the control or session protocol (C / S Protocol) between the ISCFs in the SCFs of the two networks.

[0057] Like this, under the situation that the IPTV network of Non-NGN-BASED and the NGN third-party service provider are interconnected, the above-mentioned method further includes the following processing: in the network architecture of the IPTV network of Non-NGN-BASED, through the SCF ( Denoted as the first SCF) controls the RC; in the network architecture of the NGN-BASED IPTV network, the SCF (denoted as the second SCF) controls the RACF; the IPTV service control functional entity (ISCF) of the first SCF and the second SCF ) through the control or session protocol to realize the resource control information ...

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 atransmission 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 an IPTV network, in particular to an IPTV network interconnection architecture and an interconnection method, which is mainly aimed at the interconnection of Non-NGN-Based IPTV networks and NGN-Based IPTV networks, specifically including roaming and third-party providers interconnection situation. Background technique [0002] IPTV, or Interactive Network Television, is a brand-new technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with various 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 the broadband cable TV network, use the home TV as the main terminal appliance, and provide various digital media services including TV programs...
