Disclosed is a method for connecting a mobile communication terminal with an access point located in a local area providing a Wireless Local Area Network (WLAN) service in which a server managing the access point compares Media Access Control (MAC) information of the mobile communication terminal or MAC information of the access point transferred from the mobile communication terminal through a mobile communication network with MAC information previously stored in the server and transfers network setting information required for connection to the access point to the mobile communication terminal if the MAC information of the mobile communication terminal or access point is identical to the MAC information previously stored in the server.

The invention provides a hydraulic oil cylinder convenient to install and fix. The hydraulic oil cylinder includes a fixing unit, a hydraulic cylinder body, a supporting unit and an external connection unit; the lower end of the hydraulic cylinder body is installed on the fixing unit in a clamping mode, the outer wall on the middle part of the hydraulic cylinder body is connected with the supporting unit, the other end of the supporting unit is installed on the fixing unit in a sliding fit mode, and the top end of the hydraulic cylinder body is connected with the external connection unit. Thehydraulic oil cylinder can solve the mainly existing problems of existing hydraulic oil cylinders during use that a, when the hydraulic oil cylinders are fixed to external connecting pieces, the connection is not firm, and looseness and falling are caused when the hydraulic oil cylinders are connected with external components; and the top ends of the hydraulic oil cylinders are each of a straighttube type and difficult to be connected and fixed to the external components; and b, after installation and use, the hydraulic oil cylinders can only be subjected to linear movement in a fixed direction in most cases, so that great limitations are caused in the using process of the hydraulic oil cylinders.
