Abstract

There is a demand for a technique that enable plural terminals devices to be easily paired with plural mobile terminals possessed by their respective users in a room where the terminal devices that can be shared among the users are installed. Each terminal device searches for mobile terminals present within the wireless range. If the plural mobile terminals are present within a searchable area, the search result indicates plural mobile terminals, making it difficult to determine with what mobile terminal should the terminal device be paired. The current states of various sensors of the mobile terminals are included in information indicating the names of the mobile terminals and are searched by the terminal device. Under circumstances where the plural terminal devices and the plural mobile terminals exist within short distances, the mobile terminal unit to be paired with the terminal device can be found with ease.

Claims

1. A terminal coordinating method for forming one pair of a terminal device and a mobile terminal unit from plural terminal devices and plural mobile terminal units which can be paired together in various combinations and sending and receiving data between the terminal device and mobile terminal unit of the formed pair, the method comprising the steps of:

paring together the terminal device and the mobile terminal unit such that a key is shared between these device and unit;

performing a login to an OS (Operating System) of the terminal device using the shared key;

then decoupling the terminal device and the mobile terminal unit from each other;

performing a logout from the OS of the terminal device;

recoupling together the terminal device and the mobile terminal unit of the pair which were paired together at least once;

coupling together one terminal device and one mobile terminal unit which were paired together once and performing a logout from the OS of the terminal device using the key shared in the pairing when data is sent and received between these terminal device and mobile terminal unit; and

discarding the shared key when the record of the pairing between the terminal device and the mobile terminal unit which were paired together once should be erased.

2. The terminal coordinating method according to claim 1,

wherein during the pairing step, a first one of the terminal devices sends a search request to plural mobile terminal units, each mobile terminal unit receiving the search request performs an operation for obtaining sensor information, and sends terminal information about the terminal itself and the sensor information to the first terminal device, the first terminal device displays mobile terminal information about the plural mobile terminal units and sensor information, accepts an operation performed by a user to select a mobile terminal unit according to the displayed information,

wherein if the operation to select a mobile terminal unit is not performed, the process goes to the aforementioned step for searching for a mobile terminal unit, and

wherein if the operation to select a mobile terminal unit is performed, the first terminal device is paired with the selected mobile terminal unit, and sends a pairing request to the selected mobile terminal unit, the selected mobile terminal unit is paired with the first terminal device according to the received pairing request, stores generated pairing information in the mobile terminal unit itself, and sends back the generated pairing information to the first terminal device, the first terminal device stores the sent pairing information, and the first terminal device and the selected mobile terminal unit send and receive data to and from each other.

3. The terminal coordinating method according to claim 2, wherein, if the sensor information indicates vibrations, a display portion of the first terminal device displays an icon depicting the mobile terminal unit while vibrating the icon when the sensor information is displayed.

4. The terminal coordinating method according to claim 2,

wherein during an operation for recoupling the first terminal device and the mobile terminal unit which were paired together at least once, the first terminal device displays sensor request information, the mobile terminal unit obtains sensor information responsive to a user'"'"'s manipulation according to the sensor request information displayed on the first terminal device, and sends terminal information about the first terminal device itself and the sensor information to the first terminal device, the first terminal device compares the displayed sensor request information and the sensor information received from the mobile terminal unit,

wherein if the compared pieces of information are not coincident, the process is repeated from the operation of displaying the sensor request information, and

wherein if the compared pieces of information are coincident, stored pairing information is obtained, a communicating party to be coupled is determined as the mobile terminal unit, a coupling request is sent to the mobile terminal unit, the mobile terminal unit obtains the stored pairing information and sends a coupling response to the first terminal device, and the first terminal device and the mobile terminal unit send and receive data to and from each other.

5. The terminal coordinating method according to claim 4, wherein the sensor request information displayed on the terminal device instructs the mobile terminal unit to operate.

6. The terminal coordinating method according to claim 1, wherein each piece of information of terminal information and sensor information sent from the mobile terminal units to the terminal devices includes a character string in which a character substring indicating terminal information and a character substring indicating sensor information are concatenated together by a character substring indicating a delimiter.

7. The terminal coordinating method according to claim 1, wherein during the operation for storing pairing information, the first terminal device and the mobile terminal unit send the pairing information about each terminal itself to server equipment coupled via a network (90), and wherein during the operation for obtaining pairing information, the first terminal device and the mobile terminal unit obtain the pairing information about each terminal itself from the server equipment.

8. The terminal coordinating method according to claim 1, wherein if a mobile terminal unit which has been paired is selected during the operation for selection, the first terminal device displays an error message and interrupts the pairing operation.

9. The terminal coordinating method according to claim 1, wherein the mobile terminal units ask users to make a check or enter secret information after the pairing request is received or after the coupling request is received.

10. The terminal coordinating method according to claim 1, wherein the mobile terminal units do not respond to the search request after paired with the first terminal device or after the coupling operation is complete.

11. The terminal coordinating method according to claim 1, wherein each of the mobile terminal units vibrates itself when the mobile terminal information and the sensor information is sent.

12. A terminal coordination system in which a terminal device and a mobile terminal unit are coupled together via wireless communications,

wherein the terminal device has a communication portion for sending and receiving data to and from the mobile terminal unit via the wireless communications, a display portion for displaying information about the mobile terminal unit searched for, a pairing operation portion for pairing this terminal device with the mobile terminal unit such that a key is shared between them, a coupling operation portion for performing recoupling using the shared key after the pairing, and a pairing information storage portion for storing pairing information used by both the pairing operation portion and the coupling operation portion, and

wherein the mobile terminal unit has a communication portion for sending and receiving data to and from the terminal device via the wireless communications, a pairing operation portion for pairing this mobile terminal unit with the terminal device, a coupling operation portion for performing recoupling using the shared key after the pairing, a pairing information storage portion for storing pairing information used by both the pairing operation portion and the coupling operation portion, and a sensor processing portion for obtaining sensor information from a sensor device.
