Abstract

A connection processing method includes receiving, by a first processor included in a communication device, first information that specifies a user of the communication device, executing an inquiry for a connection to one or more other communication devices, selecting a target communication device that has transmitted a response including information indicating that the target communication device has second information that specifies the user and has been acquired when the target communication device communicated with another communication device, from among the one or more other communication devices, and transmitting the first information to the target communication device, and receiving, by a second processor included in the target communication device, the first information from the communication device, executing connection processing without executing authentication processing of the user with the communication device, when the received first information matches with the second information, and executing a communication with the communication device.

A connection processing method executed by a communication system including a communication device and one or more other communication devices, the communication device having a first processor and a first storage device, the first processor being configured to execute a first program stored in the first storage device, the one or more other communication devices respectively having a second processor and a second storage device, the second processor being configured to execute a second program stored in the second storage device, the connection processing method comprising:

executing the first program, by the first processor, so as to;

store information including user specific information that specifies a user of the communication device and radio address information of the communication device in the first storage device;

execute an inquiry for a connection to the one or more other communication devices so that the first processor is configured to send the inquiry to the one or more other communication devices;

receive a response of the inquiry which includes at least a flag indicating presence or absence of the information in the one or more other communication devices and determine whether the flag has been set on to indicate the presence or set off to indicate the absence, the response including a first response and a second response,

selecting a target communication device that has responded among the one or more other communication devices, the target communication device including a first target communication device and a second target communication device;

transmitting the information to the selected first tar et communication device upon receipt of the first response transmitted from the first target communication device, the first response including the flag indicating the absence of the information in the second storage device; and

receive the second response transmitted from the second target communication device, the second response including the flag indicating the presence of the information in the second storage device and the radio address information, extract the radio address information from the second response, determine whether the extracted radio address information exists in the first storage device, and transmit the information to the second target communication device when the extracted radio address information exists in the first storage device;

executing the second program, by the second processor in the first target communication device, so as to;

receive the inquiry sent from the communication device;

transmit the first response to the communication device;

receive the information from the communication device and store the information in the second storage device; and

execute a communication between the communication device and the first target communication device without executing user-authentication processing; and

executing the second program, by the second processor in the second target communication device, so as to;

receive the inquiry sent from the communication device;

transmit the second response to the communication device;

receive the information from the communication device and determine whether the information transmitted from the communication device and the information stored in the second storage device match one another; and

execute a communication between the communication device and the second target communication device without executing the user-authentication processing when the information transmitted from the communication device and the information stored in the second storage device match one another.

2. The connection processing method according to claim 1,
