Automatic network retrieval and display device

Abstract

An automatic network retrieval and display device including: a transmission/reception processing unitthat receives information on at least one existing network and extracts error information and the like; a data conversion processing unitthat decides a connection state of each network on the basis of extracted information and outputs packet information lists in descending order of excellence in connection state; a network monitor processing unitthat extracts radio field intensity information from a network identifier and creates network identification information lists in decreasing order of radio field intensity; a network information establishment processing unitthat establishes a connection priority based on a communication state of the network on the basis of the network identification information list and the packet information list; a network switch processing unitthat connects to a network with a high priority on the basis of the connection priority of the network; and, a display unitthat displays a terminal on the connected network. This device can keep track of the communication state without requiring transmission of a packet used exclusively for displaying a communication state or requiring any terminal as a destination for transmission, and is connectable automatically to a network with a high priority.
