embodiment
[0042](Embodiment)
[0043]Hereinafter, an embodiment will be described with reference to the drawings. In the present embodiment, a communication system will be described as an example, but the exemplary embodiments are not limited thereto. A communication apparatus that realizes the function of such a communication system, a communication method performed in such a communication system, or a computer-readable storage medium having stored therein a communication program to be executed in such a communication system, may be used.
[0044](Configuration of Hardware of Game Apparatus)
[0045]The communication system of the present embodiment is composed of a plurality of communication apparatuses capable of performing wireless communication. In the present embodiment, a game apparatus 10 of hand-held type having a wireless communication function is used as an example of the communication apparatus.
[0046]FIG. 1 is a block diagram showing a non-limiting example of the configuration of the game ...
first modification
[0097](First Modification)
[0098]With reference to FIG. 10, wireless communication performed in a communication system of the first modification will be described. In the above embodiment, the search request signal transmitted from the game apparatus X includes information about the communication channel used by the game apparatus X (search communication apparatus). In the first modification, the search response signal includes information about the search period in addition to the information about the communication channel.
[0099]FIG. 10 shows the wireless communication performed in the communication system of the first modification, in chronological order. It is noted that the order of the priorities of transmission of search response signals set for the game apparatuses A to I are, starting from the highest one, B→C→D→E→H→A→F→G→I.
[0100]As shown in FIG. 10, the game apparatus X which has used the communication channel (1Ch) switches the use channel to the search channel (2Ch), and ...
second modification
[0107](Second Modification)
[0108]In the first modification, information indicating the search period is written in the search request frame D1a, which is transmitted as a search request signal. However, the information indicating the search period may not be directly included in a search request signal (search request frame D1a) as described above. In the second modification, for example, a search end notification frame (not shown) may be prepared in the transmission frame buffer area D1, and the transmission enabled period in which a search response signal can be transmitted may be determined by transmission of the search end notification frame. That is, when the game apparatuses A to I (search subject communication apparatuses) have received the search end notification frame transmitted from the game apparatus X (search communication apparatus), the search response signal transmission control means may control transmission of search response signals. It is noted that the search en...
