Some demonstrative embodiments include apparatuses, systems and/or methods of managing an Application Service Platform (ASP) session. For example, an apparatus may include a first ASP to communicate with a second ASP via a wireless Peer-to-Peer (P2P) connection over a P2P link to manage an ASP-session between a first device including the first ASP and a second device including the second ASP. The first ASP may communicate with the second ASP a message to close the ASP-session, the message including a reason field including an indication of a reason for closing the ASP-session.
