The invention relates to a connection method and device for a mobile terminal and a server side. The connection method for the mobile terminal and the server side comprises the following steps of obtaining network connection information of the server side according to a display icon of the server side, wherein the network connection information comprises each IP (Internet Protocol) address; and detecting whether each IP address and the network connected to the mobile terminal currently are in the same network segment in sequence, if yes, connecting the mobile terminal and the IP addresses in the same network segment. Another connection method for the mobile terminal and the server side comprises the following steps of obtaining network connection information of the server side, wherein the network connection information comprises each IP (Internet Protocol) address; and generating a display icon of the server side according to the network connection information, wherein the display icon is used for providing each IP address of the server side for the mobile terminal. According to the method and the device, operating steps which are needed when the mobile terminal is connected to the server side are greatly simplified, so that a process for connecting the mobile terminal and the server side is simpler and more convenient.
