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. | 2012-05-03 |
| 20120106515 | RANGING OF TERMINAL IN LEGACY SUPPORT MODE - The present invention relates to a broadband wireless access system, and more particularly, a ranging technique of a terminal using a legacy support frame in a mobile communication system including a legacy system and an advanced system. According to one form of an embodiment of the present invention, the ranging method of the terminal for a base station in the mobile communication system having the legacy system and the advanced system comprises the steps of: receiving secondary super frame header (S-SFH) information from the base station; determining whether a frame composition used in the mobile communication system supports the legacy system; acquiring ranging channel information for initial ranging, handover ranging, and periodical ranging from the S-SFH; and performing one or more ranging processes of the initial ranging, the handover ranging, and the periodical ranging in the base station by using the ranging channel information. | 2012-05-03 |
