Abstract
A portable subscriber unit (122) and a controller (112) cooperate to maintain (402) a table (226, 326) identifying operations that utilize location information, and corresponding resolutions preferred for the location information when performing ones of the operations. When a request to perform an operation is received (404), the portable subscriber unit and the controller cooperate to select (408) a resolution preferred for the operation, in response to the request; and then to determine (414) and report (418) the location information at the resolution preferred for the operation.
