ROAMING SUPPORT IN STATIONARY WIMAX NETWORKS

摘要

The invention provides for roaming support in stationary WiMAX networks. To this purpose, the network is provided with a home agent (HA) and a foreign agent (FA), which are preferably co-located in one unit (FA/HA). A roaming mobile station that supports Mobile IP (MIP) can be attached to the network as follows. After performing an access authentication procedure and establishing a connection between the mobile station (MS) and the network, a MIP agent advertisement message (MIP Adv(CoA)) is sent from the foreign agent (FA) to the mobile station (MS). Then a registration with the home agent (HA) is performed.
