A system and method for communication element to realize multicast service and network TV service

Abstract

The present invention discloses a system and a method that can realize the multicast service and the network television service of a communication element, wherein the system comprises a multicast service module, an IPTV service module and an IPTV service switch. The multicast service module is used to realize the retransmission of multicast protocol messages and data; positioned between the multicast service module and the IPTV service module, the IPTV service switch is used to turn on or off the IPTV service module; and the IPTV service module is used for service management and verificationof user rights. By the cooperation of the multicast service and the IPTV service, the turn-on or turn-off of the IPTV service is independently controlled, and by the switching of modes, the occupation of system resources by the IPTV service module is almost reduced to zero under the condition that the network element turns off the IPTV service. When the network element is needed to provide the IPTV service, the service can be conveniently turned on, thus flexibly configuring different application models of services, and when the IPTV service is turned off, the system resources can be saved.

Description

technical field [0001] The present invention relates to a multicast service and an IPTV service, in particular to a system and method for realizing a multicast service and an IPTV service on a communication network element, especially on a network element of an access network. Background technique [0002] With the increasing popularity of multicast and IPTV (Internet Protocol Television, Internet Protocol Television, Internet TV) services, communication equipment, especially broadband access equipment, usually provides support for multicast and IPTV services. [0003] For broadband access network element equipment, the multicast service and IPTV service are handled as two services, but there is a close relationship between them. The multicast service is a relatively basic service and does not depend on IPTV; while the IPTV service is based on the multicast service and realizes more complex management functions, such as program management, user authority authentication, log ...

AI Technical Summary

Problems solved by technology

[0009] However, in the prior art, some access network element devices can only provide support for multicast services, but cannot support IPTV services; although some access network element devices support multicast services and IPTV services, the service configuration Not flexible enough, only multicast service and IPTV service can be enabled at the same time; some access network elements may not enable IPTV service, but only close IPTV-related functions, and related tasks of the IPTV service module are still running, occupying processor and memory and other resources
