Problems solved by technology

[0004] Due to the extension of time for discovery, there are problems of deterioration of user operability and increase of power consumption
Also, when there are multiple candidates of the wireless way and they cannot be used simultaneously, the combination is further increased, which prolongs the time for discovery

example 1

[0062] exist figure 1 In the wireless communication system 10 shown, each of the wireless terminals 101, 102 has not been aware of the mutual existence, and does not know whether radio waves can reach. Assume that each terminal has communication unit 112 (see Figure 4 ) same as wireless LAN. Although the terminals are not aware of each other's presence, they try to search for nearby terminals.

[0063] The terminals share rules for outputting neighborhood wireless search parameters based on some input. The output is uniquely determined. In this example, the wireless channels on which to perform the search and wait are output as neighborhood wireless search parameters. In the present invention, the above rules are not strictly limited except that the output is uniquely determined. However, it is preferable that there are no large deviations in the relationship between input and output. In this example, location information is used for this input.

Abstract

The present invention enables the rapid discovery of a connection partner wireless terminal without information pertaining to a scan being shared ahead of time. Search parameters for searching for a wireless terminal that is the subject of a search are determined by means of a pre-set correspondence from predetermined information. A search process is performed, on the basis of the search parameters, to discover the wireless terminal that is the subject of a search. For example, the predetermined information is position information for the terminal in question, information unique to the wireless terminal that is the subject of a search, or the like. Also, for example, the search parameters are a wireless method, a wireless channel, a network identifier, a search execution timing, or the like.

Description

technical field [0001] The technology relates to a wireless terminal, a search processing method for the wireless terminal, and a wireless communication system. Specifically, the present technology relates to a wireless terminal that first searches surrounding wireless terminals at the time of connection, and the like. Background technique [0002] In a wireless system (wireless communication system) having a plurality of operation channel candidates, the first step at the time of connection is to search for surrounding wireless terminals. When performing searches without being aware of mutual existence, as a normal search procedure, each wireless terminal sequentially switches wireless channels, and further temporarily switches the functions of the active search side (or notification side) and the waiting side. [0003] Such steps guarantee mutual discovery at any point in time. However, discovery is generally not possible if there is no simultaneous provision of wireless...
