ABSTRACT:
A Universal Plug-and-Play (UPnP) device (200) determines a latency and propagation delay period (LPDP) that is added to a UPnP network (100) response time, based on UPnP network (100) conditions. The UPnP device (200) transmits a search command when connecting to the UPnP network (100), and waits a period of time based on the LPDP for a response to the search command from other UPnP devices (113) in the UPnP network (100) before the UPnP device (200) stops listening for other UPnP devices (113).
