ESTABLISHING A WIRELESS LINK CONNECTING A CENTRAL TERMINAL AND A SUBSCRIBER TERMINAL OF A WIRELESS TELECOMMUNICATIONS SYSTEM

摘要

The present invention provides a channel selection controller and method for establishing a wireless link connecting a central terminal and a subscriber terminal of a wireless telecommunications system, at least two frequency channels being provided over which said wireless link could be established. The channel selection controller comprises: a storage for storing data identifying the at least two frequency channels; a selector for selecting a frequency channel from those listed in said storage; and link acquisition logic for establishing a wireless link on the frequency channel selected by the selector. Further, the selector is responsive to the link acquisition logic being unable to establish said wireless link, to select an alternative frequency channel from those listed in said storage. By this approach, it is possible to increase the number of subscriber terminals that can be supported by the wireless telecommunications system, since if one frequency channel is fully used at the time that a wireless link connecting a particular subscriber terminal with a central terminal is required, then another frequency channel can be selected for the establishment of that wireless link.
