Problems solved by technology

Although we can effectively solve the problems of large traffic and point-to-multipoint through multicast technology, the requirements of mobile terminals for their moving range and moving speed are constantly increasing, which makes the management of WLAN networks decentralized, slow in deployment, and complicated in operation. , has brought us a lot of inconvenience
[0003] For the problem of decentralized multicast information management in related technologies, no effective solution has been proposed so far

Embodiment 1

[0062] Figure 10 It is a schematic diagram of the process of receiving multicast data when a terminal accesses the network through a fat AP according to the preferred embodiment 1 of the present invention, as shown in Figure 10 As shown, the process steps are as follows:

[0063] Step S1002, the terminal accesses the network through the fat AP;

[0064] Step S1004, the fat AP establishes and maintains relevant information of the terminal, such as MAC address, IP address, access AP address, security context and other information.

[0065] In step S1006, the fat AP reports relevant information of the terminal to the WMS, such as MAC address, IP address, access AP address, security context and other information.

[0066] Preferably, the information reported by the fat AP to the WMS may be the same as the information reported when accessing the network.

[0067] In step S1008, the WMS updates the above information of the terminal in its own information management entry.

Embodiment 2

[0077] Figure 11 It is a schematic diagram of the process of terminal accessing the network (via AC) and receiving multicast data according to the second preferred embodiment of the present invention, as shown in Figure 11As shown, the AC here has the function of directly obtaining the multicast group information of the terminal from the IGMP Report message sent by the terminal, without interacting with the AP. The process steps are as follows:

[0078] Step S1102, the terminal accesses the network through an AP (thin AP);

[0079] In step S1104, the AP establishes and maintains relevant information of the terminal, such as MAC address, IP address, access to AP, security context and other information.

[0080] In step S1106, the AP reports the address information of the access terminal to the AC, such as MAC address, IP address, access AP, security context and other information.

[0081] In step S1108, the AC updates the relevant information of the terminal into the manag...

Embodiment 3

[0095] Figure 12 It is a schematic diagram of the process of terminal accessing the network (via AC) and receiving multicast data according to the third preferred embodiment of the present invention;

[0096] Here, the AC does not have the function of directly obtaining the terminal's multicast group information from the IGMP Report message sent by the terminal, and needs to report the terminal's multicast group information to the AC through the AP. The process steps are as follows:

[0097] Step S1202, the terminal accesses through an AP (thin AP);

[0098] In step S1204, the AP establishes and maintains relevant information of the terminal, such as MAC address, IP address, access to AP, security context and other information.

[0099] In step S1206, the AP reports the address information of the access terminal to the AC, such as MAC address, IP address, access AP, security context and other information.

[0100] In step S1208, the AC updates the relevant information of t...

Abstract

The invention discloses a multicast information processing method and device, and a multicast information sending method and device. The multicast information processing method comprises the steps that a WMS receives request information, wherein the request information carries multicast information of a terminal; the WMS finds a manage entry corresponding to the terminal according to the request information and stores and / or updates the multicast information in the manage entry corresponding to the terminal. Through the multicast information processing method and device, and the multicast information sending method and device, the problem that multicast information in the prior art is decentralized in management is solved, and the processing efficiency is improved when a multicast group is accessed into the terminal and cross-regional switching is conducted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multicast information processing method, a multicast information sending method and a device. Background technique [0002] With the rapid development of Wireless Local Area Networks (WLAN for short) in recent years, the number of mobile terminals has increased rapidly and their intelligence has been greatly improved. People's demand for using mobile terminals to access the Internet anytime and anywhere is increasing, many of which are high-bandwidth multimedia applications, such as network video conferencing, network audio / video broadcasting, stock market quotation release, multimedia distance education, or mobile advertising and so on. These services have the characteristics of large traffic and point-to-multipoint. Although we can effectively solve the problems of large traffic and point-to-multipoint through multicast technology, the requirements of mobile terminals for t...
