Method for realizing seamless roaming between routers

Abstract

The invention discloses a method for realizing seamless roaming between routers. A plurality of sub routers are respectively in wireless bridge connection with a main router; then, each sub-router respectively receives the IP address sent by the main router, each sub-router respectively closes the DHCP server at the same time, and the main router opens the DHCP server to ensure that the network segments of the IP addresses allocated by the main router are the same, so the roaming devices can communicate with each other; further, the main router detects a PING time value of each sub-router andreply PING time data of the main router; the shortest PING connection time of the roaming equipment in which router is located is obtained; meanwhile, whether the router is in wireless network connection with the roaming equipment or not is judged: if not, responding to a roaming equipment data information simulation instruction sent by the main router, and establishing virtual data information ofthe roaming equipment, so the router normally receives and sends a WIFI data packet of the roaming equipment, thereby finishing a seamless roaming process.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method for realizing seamless roaming between routers. Background technique [0002] Currently, within the range covered by the wireless network, users may be on the move. However, since the signal coverage of a single AP (wireless access point) device is limited, the user often crosses from one AP coverage to another AP coverage during the moving process. In order to avoid network communication interruption caused by mobile users switching between different APs, wireless roaming technology is used here. [0003] However, most router products at this stage can only realize wireless roaming, but not seamless roaming. Wireless roaming needs to re-authenticate and switch channels when switching connections to the next AP. The network freezes during the switching process of the device; although a small number of routers have achieved seamless roaming, these seamless roa...

[0003] However, most router products at this stage can only realize wireless roaming, but not seamless roaming. Wireless roaming needs to re-authenticate and switch channels when switching connections to the next AP. The network freezes during the switching process of the device; although a small number of routers have achieved seamless roaming, these seamless roaming requires two frequency bands of 2.4G and 5G to achieve seamless roaming, and the cost is relatively high
