Patent ID: 7184420

Claim:
A method for dynamically locating a wireless TCP proxy suitable for a host among a of wireless TCP proxies existing in a routing path in a wired/wireless integrated network, the method comprising the steps of: (a) transmitting a proxy change request packet from a proxy controlling the mobile host to a first higher-level proxy if a mobility of the mobile host is larger than a mobility threshold that is preset in the proxy; (b) determining whether the mobility of the mobile host is larger than a mobility threshold that is preset in the first higher-level proxy; (c) transmitting a proxy change request packet from the first higher-level proxy to a second higher-level proxy if the mobility of the mobile host is larger than the mobility threshold of the first higher-level proxy; and (d) permitting selectively the proxy to be changed to another proxy if the mobility of the mobile host is smaller than the mobility threshold of the first higher-level proxy or the second higher-level proxy.
