Problems solved by technology

[0005] However, there are many obvious deficiencies in security when providing multicast service applications such as IPTV to WiFi access terminals in the manner of sharing access links.
Since multicast analog broadcasting is usually used in IP networks to realize TV network-wide broadcasting, although we can provide authenticated users with multicast services such as IPTV through means such as user access authentication and service access authentication, the existing Under the framework of the access network system, it is still difficult to ensure the security of multicast service content transmission to WiFi access terminals

Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] figure 1 It is an example of a typical access network system structure diagram, a typical customer premises gateway 12 can be a DSL modem, an optical network unit (ONU) or a router, etc.; a typical access link mode can be a digital subscriber line (DSL), Wired or wireless access means such as passive optical network (PON) or local area network (LAN); typical network access device 21 can be digital subscriber line access multiplexer (DSLAM), optical network terminal (OLT) or network switch (SIWTCH) and other methods. The customer premises gateway 12 may itself have a WiFi interface capability or provide an access link to the WiFi access terminal through a wireless AP / WTP connected to the customer premises gateway 12 and having a WiFi interface.

Abstract

The invention provides a method, equipment and a system for providing a multicast service to a WiFi access terminal. The system comprises an WiFi access terminal, a consumer premise gateway, network access equipment and an authentication server, wherein the consumer premise gateway, the network access equipment and the authentication server are connected with the WiFi access terminal, and the WiFi access terminal initiates a consumer authentication request and negotiates a key mechanism with the authentication server; and the network access equipment obtains the key mechanism, and multicast service data requested by the WiFi access terminal are provided to the WiFi access terminal in a unicast mode after encryption processing is carried out on the multicast service data requested by the WiFi access terminal accordingly. Thereby, the safe transmission guarantee of the multicast service contents of an IPTV and the like can be provided to a mobile WiFi terminal, and the mobile WiFi terminal can process the received multicast service data by utilizing an existing WiFi safety mechanism and does not need to modify or regulate the software and the hardware of the terminal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for providing multicast services to WiFi (Wireless Fidelity) access terminals in a network access system. Background technique [0002] WiFi technology is a short-range wireless technology used in offices and homes. It uses a frequency band near 2.4GHz. Its available standards include the Institute of Electrical and Electronics Engineers IEEE802.11a and IEEE802.11b and subsequent standards under development. It has the following Advantages: first, the WiFi wave covers a wide range, and its coverage radius can reach 100 meters; second, the transmission speed is very fast, reaching 11Mbps (megabits per second), which meets the needs of personal and social informatization; third, The threshold for entering the WiFi field is low. Many people extend their broadband Internet access by installing AP / WTP (Wireless Access Point / WLAN Termination Point) in their...
