摘要:
This invention relates to the establishment of a wireless and direct communication with another device upon determination of a corresponding user's instruction by a wireless communication device previously in wireless communication with an access point, to which reconnection takes place if the communication with the other device is disconnected Accordingly, the wireless communication device determines a user's instruction for establishing a communication with another device during wireless communication with an access point and, in that case, establishes a communication wirelessly and directly with the other device without interposition of the access point; if the communication with the other device is disconnected, a reconnection with the access point takes place. That may be the case when a user inputs a wireless communication channel establishment instruction to a digital camera and printer having wireless communication functions (e.g. within a wireless communication network, such as a WLAN, comprising an access point operating in infrastructure mode), such that these devices execute a direct wireless communication establishment process (e.g. in ad-hoc mode). When the devices can seize each other, the communication channel is established. After that, the digital camera sends a sensed image to the printer, which prints the sensed image.

This invention has as its object to set a one-to-one relationship upon establishing a wireless communication channel between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information even in an environment including a plurality of wireless communication devices, and to assure simple user's operations at least until the communication channel is established. To this end, when the user inputs a wireless communication channel establishment instruction to both a digital camera and printer having wireless communication functions, these devices execute wireless communication establishment processes within an allowable time period which is specified by a time set in a timer and a retry count. When the devices can seize each other within that time period, the communication channel is established. After that, the digital camera sends a sensed image to the printer, which prints the sensed image.
摘要:
In a communication apparatus on a network where communication apparatuses perform direct communication with other apparatuses, a providing apparatus that provides communication parameters, and a reception apparatus that receives the communication parameters are determined based on information indicating the capabilities of communication apparatuses existing on the network, and a transfer direction of the communication parameters is notified to the providing apparatus and the reception apparatus thereby determined.

Communication between a wireless communication apparatus and a receiver using a plurality of communication slots is realized. Further, if trouble occurs during performing time-division wireless communication between the wireless communication apparatus and the receiver using the plurality of communication slots, the communication is continued while maintaining the same or similar communications traffic rate. A series of data is assigned to a plurality of communication slots in a first communication carrier, and communication is performed through the plurality of communication slots. If trouble occurs in a communication slot out of the plurality of communication slots, the communication is continued after changing the troubled communication slot to a communication slot of another communication carrier or another communication slot.

This invention relates to the access by a wireless communication device to a wireless network configured by a first device upon user's operation, wherein wireless communication device accesses the wireless network in response to the reception of a communication parameter sent from a second device within a predetermined time period after detection of the user's operation. Accordingly, the wireless communication device detects a user's operation for setting a communication parameter for entering a wireless network configured by a first other device, and then connects wirelessly with a second other device, measuring a time period elapsed from said detection of the user's operation; a communication parameter is received from the second other device for entering the wireless network configured by the first other device, which occurs if the user's operation is detected and if a connection with the second other device takes place before the time period measured becomes a predetermined time period; in that case, the wireless network configured by the first other device is entered, using the communication parameter received. The devices executing the wireless communication establishment processes within an allowable time period may be a digital camera and printer having wireless communication functions, whereby the digital camera sends a sensed image to the printer, which then prints the sensed image.

This invention has as its object to set a communication parameter allowing wireless communication between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information. To this end, when the user inputs an instruction to both a digital camera and printer having wireless communication functions, these devices execute parameter communication processes within an allowable time period. When the devices can detect each other within that time period, a communication parameter to be used in a second communication mode is communicated in a fast communication mode. After that, the devices start communication in the second communication mode (e.g. infrastructure) using the parameter that was previously communicated in the first communication mode (e.g. ad-hoc) which is then disconnected.

This invention has as its object to set a one-to-one relationship upon setting a communication parameter for wireless communication between a wireless communication device on the information transmitting side and a wireless communication device that receives and processes the information and to terminate the processing as an error in an environment including a plurality of wireless communication devices. To this end, when the user inputs a wireless communication channel establishment instruction to both a digital camera and printer having wireless communication functions, these devices execute communication parameter setting processes within an allowable time period. When one of the devices detects a plurality of other devices within that time period, the communication parameter setting process is terminated as an error.
