Abstract: Information is retrieved from an information source by wirelessly receiving, at a cellular telephone switch, a request by a subscriber unit for a predetermined selection of information. The request is communicated to the information source using at least one of a satellite communication system and a wireless data network. The information source retrieves the predetermined selection of information. A transmission of the predetermined selection to the cellular telephone switch is inhibited if a utilization level of at least one of the satellite communication system and the wireless data network exceeds a threshold. When the utilization level is below the threshold, the predetermined selection is communicated to the cellular telephone switch. The predetermined selection is then forwarded to the subscriber unit when a utilization level of the cellular telephone switch is below a predetermined threshold.
