A system and a method for a wireless communication system (700) for adaptively delivering data to a wireless mobile communication device (702) based upon an availability status of the mobile device (702) in the wireless communication system (700) are disclosed. The wireless communication system (700) includes a host service (704) having data for the mobile device (702); a wireless router system (710) coupled to the host service (704) for determining the availability status of the mobile device (702) in the wireless communication system (700); and a wireless network (724) coupling the wireless router system (710) and the mobile device (702). The host service (704) transmits the data for the mobile device (702) if the availability status of the mobile device (702) is available, and queues the data in the host service (704) if the availability status of the mobile device (702) is unavailable until the availability status of the mobile device (702) becomes available.
