Embodiment 1

[0039] According to an embodiment of the present invention, a multicast tunnel optimization method is provided, image 3 It is a flow chart of the multicast tunnel optimization method according to Embodiment 1 of the method of the present invention, as image 3 shown, including the following processing:

[0040] Step S302, when a tunnel is established between the home agent and the foreign agent, in the first-level encapsulation of the multicast service message, use the multicast address or the specially defined address of the multicast service of the mobile station as the destination address of the encapsulation, and the second The header of the multicast service message encapsulated at the first level is extended to indicate and carry the home addresses of multiple users and the establishment of a dedicated tunnel.

[0041] In addition, in the second-level encapsulation of the multicast service message, the care-of address is used as the encapsulation destination address, a...

Embodiment 2

[0047] In the first method embodiment, since the length of the IP packet / header is generally limited, it is unlikely to carry a large number of IP addresses. In this embodiment, a new method is provided for transferring user addresses. When there are a large number of IP addresses When the address needs to be transmitted, a dedicated message can be further defined. Next, the above technical solution will be described in detail.

[0048] According to an embodiment of the present invention, a method for optimizing a multicast tunnel is provided, Figure 4 It is a flow chart of the multicast tunnel optimization method according to the second embodiment of the method of the present invention, such as Figure 4 shown, including the following processing:

[0049] Step S402, when establishing a tunnel between the home agent and the foreign agent, define a dedicated message, and carry a plurality of home addresses of users with the same multicast service and the multicast address of...

Abstract

The invention discloses a multicast channel optimizing method, a device and a system; the method includes that when a channel is established between a local agent and a foreign agent; in the first grade encapsulation of the multicast service message, the multicast address of the multicast service of the mobile station or the particularly-defined address is used as the destination address of the encapsulation; the message head of the multicast service message in the first grade encapsulation is extended to indicate and carry the source addresses of a plurality of users. Based on the technical proposal, the multicast service transmission of the mobile users is optimized and the consumption of the network bandwidth resource is reduced.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a multicast tunnel optimization method, device and system. Background technique [0002] Multicast and Broadcast Services (MCBCS) in Worldwide Interoperability for Microwave Access (WiMAX) is a system for realizing multicast and broadcast services, and it is a system that simultaneously provides services to Business system with multiple users. Through MCBCS, WiMAX network operators can provide users with a large number of services. [0003] figure 1 It is an MCBCS network structure diagram, including multicast and broadcast service MCBCS controllers, AGW (authenticator), base station (Based Station, referred to as BS), mobile station (Mobile Station, referred to as MS) and other functional entities. In order to realize the MCBCS service, AGW, BS and MS all need to be extended to a certain extent. In the MCBCS system, in order to support mobility, it also includes...
