  • Patent number: 10476940
    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.

  • 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.
