摘要： A method, system, and apparatus for managing spreading codes used in communication over a radio frequency air interface. When a radio access network (RAN) is to assign a spreading code to a mobile station in the coverage area, the RAN may determine which mobile station currently having an assigned traffic channel in the coverage area has a highest forward-link signal quality, and the RAN may select a spreading code based on the spreading code of that determined mobile station's assigned traffic channel. For instance, the RAN may select a spreading code that is quasi-orthogonal to the spreading code of the determined mobile station's assigned traffic channel.

摘要： The present invention provides a method and system for determining whether to accept an access request from an AT. In an embodiment of the invention, a base station receives an access request from an AT that is located within a sector served by the base station. In response to receiving the access request, the base station obtains the physical location of the AT within the sector. The base station then determines whether to accept the access request based on the physical location of the AT within the sector.

摘要： Systems and methods for dynamically adjusting the size of an access search window are provided. In an embodiment a base station uses an access search window size, which is initially set to a default value, to determine whether to accept access requests from access terminals (ATs). The base station operates to accept access requests from ATs when the ATs are within the distance defined by the value of the access search window. The base station further operates to measure an amount of traffic for a sector of a wireless coverage area and change the value of the access search window size based on the amount of traffic on the sector.
