Search methods applied to a personal network gateway in converged personal network service systems and related converged personal network service systems and mobile devices

摘要

A search method applied to a personal network gateway (PN-GW) in a converged personal network service (CPNS) system is provided. First, a search procedure to search for personal network elements (PNEs) in a specific zone of the CPNS system is periodically performed every search period. Upon expiration of each search period, whether any undetected PNE has entered the specific zone is determined and the search period is adaptively adjusted according to the determination result.
