Information processing method, device and system

The embodiment of the invention provides an information processing method, a device and a system. The method is applied to an information processing system composed of multiple pieces of equipment. Each piece of equipment in the system comprises a CMC (Center Manager Client), CMS (Center Manager Server) and a WDVR. The method comprises steps: when the WDVR in the equipment is sure that an event happens, the event is judged whether to be a linkage event in need of linkage, if yes, the WDVR reports the event to the CMS controlling the WDVR; if not, reporting is not carried out; after the CMS controlling the WDVR receives the event, an event notification message is issued to the CMC which logs onto itself and whose event in need of linkage set by itself is the event; and each CMC receiving the issued event notification message stores the event and displays the event. In the embodiment of the invention, the CMS is only in charge of partial signaling, thereby reducing load of the CMS; and as each piece of equipment is provided with the CMS, in the condition where CMSs in partial equipment fail, the CMSs in other equipment can still operate normally.
