Automatic network retrieval and display device
View Patent ↗An automatic network retrieval and display device including: a transmission/reception processing unit 2 that receives information on at least one existing network and extracts error information and the like; a data conversion processing unit 4 that 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 unit 3 that 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 unit 5 that 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 unit 6 that connects to a network with a high priority on the basis of the connection priority of the network; and, a display unit 7 that 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.
1. An automatic network retrieval and display device that is connectable to an arbitrary network and that selects a network in a condition of optimal data communications and connects to the network, the automatic network retrieval and display device comprising:
a transmission/reception processing unit that receives information on at least one existing network and extracts size information, error information and collision packet occurrence information from the received data;
a data conversion processing unit that decides a connection state of each network on the basis of a ratio of a total amount of the error information and the collision packet occurrence information with respect to the size information that are extracted by the transmission/reception processing unit, and outputs a packet information list in descending order of excellence in the connection state;
a network monitor processing unit that extracts radio field intensity information from a network identifier existing on the network, creates and outputs a network identification information list in decreasing order of radio field intensity;
a network information establishment processing unit that establishes a connection priority based on the communication state of the at least one existing network, on the basis of a combination of the network identification information list outputted by the network monitor processing unit and the packet information list outputted by the data conversion processing unit;
a network switch processing unit that is to connect to a network with a high priority on the basis of information of network connection priority established at the network information establishment processing unit; and
a display unit that displays a terminal on the network connected by the network switch processing unit.
2. The automatic network retrieval and display device according to claim 1 , wherein the transmission/reception processing unit comprises:
a reception part A that receives current data information on the basis of arbitrary communication information existing on the connected network;
a packet data storing part that stores packet data of the data information;
a supplemental data storing part that stores supplemental data contained in the data information; and
a reception data list creating part that creates a reception data list on the basis of an output of the packet data storing part and an output of the supplemental data storing part.
3. The automatic network retrieval and display device according to claim 1 , wherein the network monitor processing unit comprises:
a reception part B that receives current network information on the basis of arbitrary network information existing on the connected network;
a network identification information detecting part that detects network identification information and radio field intensity information from an output of the reception part B; and
a network identification information list creating part that creates a network identification information list on the basis of the information detected at the network identification information detecting part.
4. The automatic network retrieval and display device according to claim 1 , wherein the network information establishment processing unit comprises:
a packet information list detecting part that detects the packet information list created at the data conversion processing unit;
a network identification information list detecting part that detects the network identification information list outputted by the network monitor processing unit;
a network information comparing part that compares the detected packet information list and the detected network identification information list, compiles list information for each corresponding network so as to create a network information list; and
a connection information list creating part that establishes the connection priority for each network in the network information list and creates a connection information list for conducting a network connection on the basis of prioritized information.
