Patent number: 10037253Abstract: Fault handling methods in a home service system, and associated household appliances and servers are disclosed. According to a fault handling method, the household appliance may send a first message to a primary server, and may decide the primary server fails when not receiving a feedback connection signal from the primary server. The household appliance may then send a second message to a backup server according to pre-stored identification information of the backup server, so as to connect to the backup server. Thus, the household appliances can directly communicate with the backup server to establish connections thereto, eliminating the need of communications between the primary and the backup server, and no extra servers would be needed, which can reduce the cost, thereby avoiding the collapse of the entire home service system due to failure of the primary server.Type: GrantFiled: April 23, 2015Date of Patent: July 31, 2018Assignee: Huizhou TCL Mobile Communication Co., Ltd.Inventors: Yi Zhang, Su Lu, Teng Li
