Abstract: A subscriber unit (300) receives an inbound transmission feedback message regarding at least one inbound transmission made by the subscriber unit (401). Based on the inbound transmission feedback message, the subscriber unit updates at least one site ranking factor corresponding to the subscriber unit's current site (402). In another embodiment, a site (600) determines the signal quality information for at least one inbound transmission made by a subscriber unit (702) and, when the signal quality information is unfavorable, transmits a message instructing the subscriber unit to update at least one site ranking factor (704). The subscriber unit can compute new site rankings based on the site ranking factors and select, if necessary, a new site having a preferable site ranking (403-405).
