Method and System for Detecting Network Connection in Ipv6 Radio Access Network |
摘要 |
The technology is disclosed to attain the prompt processing and reduction of signaling volume in network attachment detection for IPv6 wireless access networks. According to this technology, a mobile node reports the identifier of a new wireless access point to its on-link access routers (ARs) and the ARs disseminate the identifiers of all the reported access points (APID List) to MNs. With the identifiers information, the MN is able to speculate it remains in the same subnet or moved back to a previously visited subnet, where its current or previous address configuration can be reused respectively. The speculation is ascertained by parallelly performing reachability test and duplicate address detection, if necessary. The reachability test is done in a unicast manner so as to conserve wireless link bandwidth.
