Abstract

An apparatus comprises a memory device and a processor disposed in communication with the memory device. The processor is configured to conduct an inquiry to discover nearby devices and to determine whether a discovered nearby device provides an indication that it may include a middleware software, the middleware software configured for providing application and service discovery. When the discovered nearby device does not provide an indication that it may include the middleware software the processor disconnects communication session establishment with the discovered nearby device. When the discovered nearby device provides an indication that it may include the middleware software, the processor creates a wireless short-range communication connection to the discovered nearby device. The processor confirms whether the nearby device includes the middleware software by requesting corresponding information from the discovered nearby device via the wireless short-range communication connection and when the discovered nearby device includes the middleware software, the processor executes the middleware software to perform application and service discovery with the discovered nearby device.
