Abstract: A method for selecting a gateway node for a terminal which connects to its registered domain via an access domain and, in a predetermined scenario, an intermediate domain, the access domain having an associated domain name system arranged to return an address of a gateway node based on a domain name system query. The method includes using a first part of such a query to identify the registered domain of the terminal to the domain name system and a second part of the query to indicate to the domain name system that it should use a predetermined mapping to return the address of a gateway node based on the query, the predetermined mapping being one which returns an address of a gateway node either in the registered domain or in an intermediate domain based on the registered domain identified in the query and on the access domain.

Abstract: An appropriate quality of service policy is automatically selected as a function of network and business conditions. A current loading condition of an internet protocol network of devices operating, a current condition of radio frequency communications between wireless devices, and a current business condition that indicates a cost or availability of a resource used in device operation remotely controlled via data packet communications, are each determined under current network control and routing rules. If the resource cost or availability exceeds a specified market condition constraint, a special resource control rule is automatically selected to preempt a current network or routing rule to cause one or more of the internet protocol devices to reduce an amount of the resource used or distributed by the first internet protocol device while operating within the current determined internet protocol network loading and radio frequency communications conditions.

Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-1 and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.
