Abstract

A communications system may include data storage devices for storing data files, and mobile wireless communications devices (MWCDs) generating access requests for the data files. The data storage devices and MWCDs may each use one or more different operating protocols. Each data file may be associated with a respective MWCD and have a unique identification (UID) associated therewith. The system may also include a protocol interface device including a protocol converter module for communicating with the MWCDs using respective operating protocols thereof, and a protocol engine module for communicating with the data storage devices using respective operating protocols thereof. The protocol engine module may also poll the data storage devices for UIDs of data files stored thereon, and cooperate with the protocol converter module to provide UIDs for respective data files to the MWCDs upon receiving access requests therefrom.
