Abstract: A communication device includes a memory and a processor coupled to the memory. The processor is configured to transmit a first request to discover devices through radio communication. The processor is configured to discover first devices on basis of first responses to the first request within a predetermined period. The first responses are received from the respective first devices. The processor is configured to establish, after a lapse of the predetermined period, a connection with the respective first devices. The processor is configured to acquire information from the respective first devices.

Abstract: A task execution controller includes a context generating unit that generates context information concerning a user and a surrounding situation of the user; a task managing unit that stores multiple tasks the user attempts to execute, selects a task according to the context information and a predetermined task selection rule, and controls execution of the task; and a service managing unit that confirms services executed by a device used for execution of the task, gives notification of a service corresponding to the execution of the task selected by the task managing unit, to the device and causes the device to perform the service. The task managing unit selects a task by using, as the task selection rule, information of priority levels of tasks and an execution-related dependency relation between tasks preset among the tasks.

Abstract: According to an aspect of an embodiment, a communication terminal connectable to a communication network system transmits user data obtained by one communication terminal gaining a voice to other communication terminals through a network. The communication terminal includes a transmitter, a receiver, a voice request part which receives a voice gain request from a user, a voice gain recognition part which recognizes that the voice is gained, a data obtaining part which obtains user data, a data storage which stores data, and a data management part which causes the data storage to store the user data after receiving a voice gain request and which receives the recognition of the voice gain. The transmitter transmits the user data part after receiving the voice gain request from the user.

Abstract: A communication device implementing a function of retransmitting to a destination includes an operation unit detecting an input operation, a communication module starting a transmission to a destination specified by the input operation, a storage unit storing one or more pieces of destination specifying information on every destination, a judging module judging whether the communication can be attained upon the transmission, a searching module searching for, if judged to be impossible of the communication, one or more pieces of destination specifying information stored corresponding to the destination from the storage unit, a display unit displaying a list of the searched destination specifying information, a selection module accepting a selection of a desired piece of destination specifying information from the list of the destination specifying information displayed, and a retransmitting module retransmitting based on the selected destination specifying information.
