Embodiment Construction

[0028] Now in conjunction with the accompanying drawings, the working principle of the present invention is further described:

[0029] The system of the present invention includes:

[0030] Access times counting module: used to count the number of times the user has restricted access to the multicast group, and output a denial of access signal when the maximum allowable limited access times preset value is reached;

[0031] Access identification timing module: used to identify whether the user's access to the multicast group is browsing access or actual access;

[0032] Access time timing module: used to record the length of time the user actually visits the multicast group, and outputs a signal of denial of access when the preset value of the maximum allowed limited access time is exceeded;

[0033] Access interval timing module: used to record the time interval length of the user's two consecutive restricted access to the multicast group, and output a denial of access sign...

Abstract

This invention discloses one group broadcast business limit visit control system and method, which comprises the following steps: control module receives user limit visit group adding requires and visit timing module firstly judges user visit times to maximum permitted visit set values; then through visit time lag meter module judges the require and front visit time lag larger than preset minimum user two times of limit visit group time values, if conditions are satisfied, then receiving requires and visit identification timing module judges user group broadcast stable time over preset time value.

Description

technical field [0001] The present invention relates to a system for controlling multicast equipment in a network to provide users with limited access to multicast services, in particular to a system for controlling access equipment located at the edge of the network in the field of communications to allow users to perform limited access to multicast services . Background technique [0002] Multicast technology can enable data packets to be copied and distributed only to members of the multicast group. Compared with unicast and broadcast technologies, it is more suitable for carrying business applications such as IP / TV and network conferences that are sent in a centralized manner and received in a decentralized manner. With the development of more and more services using multicast technology as the bearer mode, some technical problems need to be solved urgently to make multicast technology have real practical value, among which how to control users' access to multicast servi...
