  • Patent number: 8954036
    Abstract: There are provided a data arrival control server and a data arrival control method, whereby in a case where an identical user uses plural communication terminals, even if a data-receiving terminal is powered off, it is made possible to know with another communication terminal that there is a data arrival at the data-receiving terminal. A data arrival notification unit 143 of a data arrival control server 10 notifies a data arrival notification target terminal 20 that there is the data arrival at a data-receiving terminal 30, when there is the data arrival at the data-receiving terminal 30.

  • Publication number: 20140134973
    Abstract: A non-billing instruction function terminates a transmission of billing source information for a billing process to a billing server, and when a PB receiving function detects switching of the content of a telephone call while the connection of a call is maintained, a billing source information transmitting function transmits the billing source information to the billing server. This eliminates an occasion that a service is applied or is not applied depending on an operation given by a user, thereby providing the service equally.

  • Patent number: 8620311
    Abstract: There is provided a communication system and a communication method of making available both a shared telephone number shared by multiple communication terminals and an individual telephone number dedicated to a user's own terminal in a single communication terminal. A shared managing unit 11 of a communication system 1 manages terminal identifiers 1 and 3 identifying each of a plurality of communication terminals 30a and 30b to which a shared telephone number is assigned in correlation with the shared telephone number. An individual managing unit 12 manages a terminal identifier 2 identifying a communication terminal 30b to which an individual telephone number is assigned is correlation with the individual telephone number. A user information managing unit 13 manages user information including base station information of communication terminals identified by the identifier every terminal identifiers 1, 2, and 3.

  • Patent number: 8396487
    Abstract: There are provided a location acquiring system that allows acquiring of location information that keeps track of the movement of a mobile communication terminal to be searched for, with the transmission and reception of signals for acquiring the location information being suppressed, and a location information acquiring method. A session establishment unit 124 of an application unit 12 in a management server 10 establishes a session between a location acquiring request terminal 20 and a to-be-searched terminal 30 for continuously transmitting the location information of the to-be-searched terminal 30 to the location acquiring request terminal 20, when an information transmission and reception unit 11 receives location information acquiring request information for making a request of acquiring location information of the to-be-searched terminal 30 from the location acquiring request terminal 20.

  • Patent number: 8380047
    Abstract: There are provided a video editing system, a video editing server and a communication terminal which enable simultaneous editing operations for editing a video content to be performed by plural persons, without generating a file in which a content of the editing has been reflected in the video content. One of a plurality of editing terminals in a synchronized state generates an edit command for editing a video content with an edit command generating section, based on an editing operation by a user from a terminal operating section, and transmits the generated edit command to a video editing server via an information transmitting/receiving section. If the edit command is received via an information transmitting/receiving section, the video editing server transmits the received edit command to another editing terminal in the synchronized state, via an edit command synchronizing section.

  • Patent number: 8243906
    Abstract: There is provided a group communication system allowing group communication to be performed by a simple operation as well as a group ID number issuing apparatus and a call control apparatus to be applied to such a group communication system. When a user takes a group organization procedure to the group communication system, a group representative telephone number representing the group is issued. After the group representative telephone number is issued, the group representative telephone number can be used in the same manner as for calling a subscriber to call a group member to perform group communication. The group communication can be performed by limiting to a lower level subgroup, a pair of the group representative telephone number and an identifier can be used instead of the subscriber's telephone number to determine the calling partner to make a call.

  • Patent number: 7945686
    Abstract: A communication control apparatus includes a registration request signal receiver, a registration section, a transmitter, a group communication control signal receiver, and a group communication controller. The request signal receiver receives, from at least one terminal differing from a plurality of group communication terminals that is performing or is to perform group communication through a communication network, a control terminal registration request signal requesting the registration of the terminal as a control terminal for controlling the group communication. The registration section registers the terminal which sent the control terminal registration request signal as a control terminal. The transmitter sends, to that terminal, information indicating that the terminal has been registered as a control terminal. The control signal receiver receives from the terminal a group communication control signal for controlling the group communication.
