  • Patent number: 10044812
    Abstract: According to an embodiment, a communication device performs communication with a terminal device via a network and includes first and second connection maintaining units and a switch instructing unit. The first connection maintaining unit maintains a connection established with the terminal device and mediates communication between the terminal device and another terminal device. The second connection maintaining unit maintains a communicable state of the terminal device with the communication device according to a method different from a method implemented by the first connection maintaining unit. When a predetermined switching condition is satisfied, the switch instructing unit instructs the terminal device to switch a method for maintaining a communicable state either from a first method, which is a method implemented by the first connection maintaining unit, to a second method, which is a method implemented by the second connection maintaining unit, or from the second method to the first method.

  • Publication number: 20170272506
    Abstract: According to one embodiment, a communication device capable of communicating with each of a control device and a processing device through a network includes processing circuitry. The processing circuitry creates a job upon receiving a first request from the control device, the first request designating a content of a process that is executed by the processing device, the job containing information to instruct the processing device to execute the process and a first time limit relevant to the process. The processing circuitry controls transition among a plurality of states of the job. The processing circuitry controls, upon receiving a second request for the job from the processing device or the control device, execution of the second request, based on the first time limit and the state of the job.

  • Publication number: 20160277413
    Abstract: According to one embodiment of the present invention, an access permission device includes a communicator, a state evaluator, an access proxy, and a determiner. The communicator communicates with a target device connected to a network, and a communication device that can use a resource provided by the target device. The state evaluator acquires the communication device information to determine a connection state with the network from at least one of the communication device and the target device, and evaluates the connection state based on the information. The access proxy transmits a use request for the resource provided by the target device to the target device. The determiner determines, based on the connection state, which of the communication device and the access proxy transmits the use request for the resource provided by the target device to the target device.
