Abstract: 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.

Via the present invention, the access device can allow the uplink valid multicast IP packet to pass, preferably, determines and intercepts the malicious attacks via multicast IP packet, so as to ensure the DSL access device's support for mobile IPv4, so as to keep the uninterrupted connection of the service to the user when the user moves between different subnets.

Abstract: The present invention provides a method for network service selection and authentication in an IPv6 access network, a scheme for stateless auto-configuration and devices thereof. A NSP Information option containing the IPv6 address of a NSP edge router and a NSP name is defined in RA messages. A NSSA Information option is defined in RS option fields. The present invention enables IPv6 stateless auto-configuration in an access network. The new NSP Information option, the way of “one time authentication per subscriber network per NSP” and the use of IPv6 routing header promote the efficiency of IPv6 stateless auto-configuration and reduce the NSP selection and authentication traffic. The present invention provides an efficient solution for network service selection and authentication without introducing any other message exchange between terminals and access nodes.

Abstract: The present invention provides a method and apparatus of providing network services to a mobile user equipment, where the mobile user equipment is connected to a fixed access network via a Femtocell base station and thus connected to the mobile core network. The mobile core network provides an access token to a Femtocell base station. The Femtocell requests the fixed access network with the access token to perform network resource configuration for the mobile user equipment. The mobile user equipment establishes a network service connection based on the network resource configuration. In this way, technically, it may be guaranteed that the mobile user equipment can be legal listened. Dependent on different service attributes of the mobile user equipment, different network access manners may be implemented, such that operators of mobile and fixed access networks may reasonably commercially apportion the charges based on their respective network resource occupation situations.
