A roaming method for a mobile terminal in a wireless local area network is disclosed. In the method, a target access point (AP) device receives an access request for roaming from the mobile terminal, and a target access controller (AC) obtains mobility information of the mobile terminal in an original extended service set based on the access request, wherein the mobility information include information of an AP device, an AC and a mobile agent server associated with the mobile terminal. Then the target AC determines whether the roaming for the mobile terminal is an inter-IP subnet roaming or an intra-IP subnet roaming based on the obtained mobility information. The target AC performs mobile IP based handover when the roaming is determined as the inter-IP subnet roaming and performs Inter Access Point Protocol based handover when the roaming is determined as the intra-IP subnet roaming.

Disclosed is a method for updating DNS of host in IPv6 stateless address auto-configuration, wherein an option is added in the RS message sent by a host and/or RA message sent by a router, said option including information for negotiation of updating DNS of host. Based on said information, the host negotiates with the router to determine whether the host or the router register, the mapping between the global address of the host and the full domain name of the host, to a DNS server, to complete updating the DNS of the host. This invention enables the host to correctly identify the matching relation between domain name suffix information and address prefix, and achieves the negotiation of updating DNS domain name between the host and the router. Since DNS updating is performed by a router instead of the host, the DNS updating would become simple and safe.

The present invention provides an improved solution of registering with a Home Agent HA of a Mobile Node MN, comprising: grouping at lest two Foreign Agents FAs to form a Foreign Agent Group FAG to enable FA members of the FAG to share information of the MN roaming into a FAG coverage area; when any FA member of the FAG receives a registration request for registering a care-of address with the HA sent by the MN, determining whether the MN enters the FAG coverage area for the first time based on the shared MN information; and if the MN enters the FAG coverage area for the first time, the FA forwards the received registration request to the HA; otherwise, the FA directly sends a registration response to the MN. The solution of the present invention greatly reduces registration messages from the MN to the HA, thereby reducing signaling delay produced when the MN moves in the FN. Also, both the MN and the HA in the prior art can be merged into the solution, thereby achieving seamless integration with IPv4, preferably with Mobile IPv4 scheme.
