Method and system for multicast charging

Abstract

A method and system for multicast billing proposed by the present invention, the access device records the user name and the media access control (MAC) address when the terminal user unicast authentication is successful; when receiving the multicast join request message sent by the user , use the monitoring function to obtain the MAC address and multicast group address of the end user from the multicast join request message, determine the user name and multicast group address according to the monitored MAC address and the recorded MAC address, and send the user name and multicast group address to the multicast accounting server The charging request carries the user name and multicast group address; the multicast charging server performs charging according to the duration of the charging request. Applying the solution of the present invention, since the access device utilizes the user name recorded in the unicast authentication process, when the terminal user joins the multicast, the access device can send an accounting request carrying the user name to the multicast accounting server to Support the multicast billing server to accurately bill end users according to the duration, thereby improving the accuracy of multicast billing.

Description

technical field [0001] The invention relates to multicast technology, in particular to a method and system for multicast charging. Background technique [0002] In the communication field, both unicast and multicast are typical ways of Internet Protocol (IP) network data transmission, and among them, multicast can effectively save bandwidth resources compared with unicast. [0003] figure 1 It is a schematic diagram of a data transmission mode of unicast communication in the prior art. Such as figure 1 As shown, assuming that end users A, B, and C need to obtain IP packets from the source server, the source server must copy multiple IP packets according to the number of end users, and then send them to different end users through each router. [0004] figure 2 It is a schematic diagram of the data transmission mode of multicast communication in the prior art. Such as figure 2 As shown in , assuming that end users A, B, and C need to obtain multicast streams from the ...

AI Technical Summary

Problems solved by technology

[0007] At present, the billing of unicast technology is relatively mature, and various billing methods such as monthly subscription and time-based billing can be adopted; while the billing of multicast technology is relatively extensive, usually only monthly billing can be used, and it cannot be ordered by end users The multicast channel is charged according to the length of time

The key reason why the multicast technology cannot be billed according to the duration is that when an end user requests a certain multicast channel, the multicast join request message sent by the end user does not carry the user name, and the billing server cannot know that the request for a certain multicast channel is ordered. The user name corresponding to the user of the multicast channel cannot accurately charge the terminal user according to the duration.
