Abstract
Abstract In a wireless communication system (100), a communication unit (102) may operate in the following manner. Upon initiation of a service request, the communication unit (102) transmits the desired service request to an application device (115) over a second wireless communication path (117). Upon receiving this request, the application device (115) prepares a service response which is transmitted back to the communication unit (102) over the second wireless communication path (117). Upon receiving the response, the communication unit (102) transmits at least a portion of the response to the wireless communication system (100).
