The invention relates to a message transmission method, device and switch. The message transmission method comprises the following steps that the switch receives a BF(non-disruptive reconfiguration) message; when the BF message carries a switch name, and the switch name carried in the BF message is different from the name of the switch, the switch retains the Domain ID (Identifier) of the switch; and the BF message is sent through a port in the switch except the port for receiving the BF message. The only communication disruption of the switch of which the name is the same as the switch name carried in the BF message and the communication non-disruption of other switches can be realized, and the serviceability of the whole network is ensured to the utmost extent.

The invention discloses a multi-beam switching method for a terminal autonomous GEO satellite mobile communication system, and mainly relates to the cross-beam switching technology in the field of satellite mobile communication. In this method, dual-channel devices are set in the mobile terminal, and through reasonable software control, the dual-channel devices reside in different beams in the beam overlapping area, and the communication data is wirelessly transmitted between the two channels when crossing beams. Slot switching transmission realizes communication continuity and integrity of data transmission when high-speed mobile users frequently cross beams. The present invention adopts the design of terminal dual-channel and autonomously switching transmission channels. Compared with the existing cross-beam switching method, it has the characteristics of not requiring system switching control, flexible and autonomous use by users, uninterrupted communication, and user-insensitive beam switching. It is especially suitable for occasions where mobile users can move freely and maintain communication continuity in a GEO multi-beam satellite system.

This application provides a roaming method and device. In this application, by modifying the TCP / IP connection established between the host and the peer from the first IP address that should be bound to the host in the first network to the first IP address that does not change with the host roaming The address of the host, so that all parameters associated with the TCP / IP connection established between the host and the peer will not change because the host roams from the first network to the second network, so even if the host roams from the first network to the second Network, the TCP / IP connection established between the host and the peer can still be maintained, which ensures that the TCP / IP connection established by the host before roaming will not be interrupted by the host roaming, and the communication will not be interrupted after the host roams.
