Location change update method and system based on physical location in local area network

The invention provides a location change update method and system based on a physical location in a local area network. The location change update method comprises the following steps: judging whether the physical location of a terminal is changed or not; when the physical location of the terminal is changed, acquiring location change operation of a user; and updating a location of an information point corresponding to the terminal in a management-control physical map layer according to a new physical location of the terminal included in the location change operation. According to the method, the physical map layer based on the physical location is taken as an interface for managing and controlling an enterprise Intranet terminal, the location of each information point on the management-control physical map layer is correspondingly correlated with physical location information of the terminal, and the information in the management-control physical map layer is updated in real time according to the location change of the terminal, so that a management-control process performed on the enterprise Intranet terminal is visualized and simplified; the management and control of the enterprise Intranet terminal tend to administrative participation; and the use experience of the user can be improved.
