摘要:
In a communication system, a first wireless communication apparatuses belonging to a communication group receives a connection request frame including a notifying security level from a second communication apparatus outside of the communication group. The first communication apparatus stores a reference security level peculiar to the communication group, which is selected from security levels depending on one of encryption methods including non-encryption and encryption strengths. In the first communication apparatus, the notifying security level is compared with the reference level, and a response frame including one of a connect rejection and a connection permission is described, is generated and transferred to the second communication apparatus. The connect rejection represents a rejection of connection to the second communication apparatus and the connection permission represents a permission of connection to the second communication apparatus.
摘要:
An interface control device includes a first interface, a second interface, a third interface and an interface controller. The first interface is used to communicate with a first information processing device. The second interface is used to communicate with a second information processing device. The second information processing device is different from the first information processing device. The third interface is used to communicate with a controller of a data-storage medium. The interface controller performs an interface control including transmission of an indication signal through the first interface after the communications through the second interface with the second information processing device are established. The indication signal indicates the first information processing device of the fact that communications through the second interface have been established.

A radio communication apparatus includes: a first communication unit having a first communication coverage including a short-distance portion and a long-distance portion; a second communication unit having a second communication coverage including at least the long-distance portion; a reception detecting unit detecting that a short-distance communication request transmitted from a first communication unit of an other communication apparatus has been received by at least one of the first and second communication units; a determining unit permitting the request when the request is received by the first communication unit and not received by the second communication unit, and rejecting the request when the request is received by the second communication unit; and a communication processing unit carrying out short-distance communication with the other communication apparatus via the first communication unit when the request is permitted.
摘要:
A communication system including a first terminal device connected to first and second networks, having only a reception function with respect to the first network and transmission and reception functions with respect to the second network, the first network being a radio network according to IEEE 802.11 and the second network being a radio network slower than the first network, and a second terminal device connected to the first and second networks, having at least a transmission function with respect to the first network and transmission and reception functions with respect to the second network is disclosed. In this communication system, the first terminal device carries out a prescribed procedure required in using the first terminal as a receiving side in the first network, by carrying out communications with the second terminal device through the second network, the second terminal device transmits a prescribed information to the first network on behalf of the first terminal device, the prescribed information being an information required to be transmitted to the first network in order for the first terminal device to receive packets through the first network, and the first terminal device receives the packets through the first network.

摘要:
A wireless base station which controls joining of a plurality of wireless terminals to a wireless network, stores a maximum joining possible terminal number which indicates a maximum number of the wireless terminals of each terminal type that can join the wireless network simultaneously, and which is set in advance for each one of a plurality of terminal types that classify the wireless terminals, and a currently joining terminal number which indicates a number of the wireless terminals of each terminal type that are currently joining the wireless network, for each one of the plurality of the terminal types. Then, the wireless base station judges whether the joining of one wireless terminal of one terminal type which sent a request message to the wireless network is permitted or not, according to the maximum joining possible terminal number for the one terminal type and the currently joining terminal number stored for the one terminal type.
摘要:
A wireless communication circuit includes a receiver to receive at least one of a beacon frame and a probe response frame from a first wireless communication apparatus belonging to a first communication group, at least one of the beacon frame and the probe response frame including first security information indicating a first encryption method. The circuit includes a transmitter to transmit an association request frame to the first wireless communication apparatus, the association request frame including second security information indicating a second encryption method which is supported by the wireless communication circuit, after a determination that the second encryption method overlaps with the first encryption method. The transmitter declines to associate with the first wireless communication apparatus if the first encryption method fails to overlap with the second encryption method. The transmitter transmits a data frame including a frame body after a reception of an association response frame.
