Apparatus and method to perform screen sharing between terminal devices in a wireless network via another wireless network

1. An apparatus comprising:

a memory; and

a processor coupled to the memory and that:

delivers, via an access point and over a first wireless network, display information to terminal devices on the first wireless network;

obtains, from the access point, connection status information that represents a connection status between each of the terminal devices and the first wireless network via the access point;

detects, using the connection status information and from among the terminal devices, a first terminal device whose connection to the first wireless network via the access point is disconnected and a second terminal device whose connection to the first wireless network via the access point is connected; and

transmits, to the second terminal device over the first wireless network, an instruction to:

transmit, without going through the access point and from the second terminal device to the first terminal device over a second wireless network that is different from the first network, display information displayed on the second terminal device,

wherein the second terminal device receives, over the first wireless network, the display information displayed on the second terminal device.

2. The apparatus of claim 1 , wherein the processor further:

delivers, to each of the terminal devices, a beacon pattern assigned to each of the terminal devices, wherein the beacon pattern is a combination of transmission frequency channels of a beacon used for the second wireless network; and

broadcasts, based on a beacon pattern assigned to the first terminal device, a beacon including an instruction for receiving the display information displayed on the second terminal device.

3. The apparatus of claim 2 , wherein the processor further:

extracts, based on the connection status information, a disconnection time at which connection between the first terminal device and the first wireless network via the access point is disconnected;

transmits, by broadcasting a beacon including the disconnection time based on the beacon pattern assigned to the first terminal device, the instruction for receiving the display information displayed on the second terminal device to the first terminal device, wherein the instruction holds the disconnection time; and

transmits, to the second terminal device, address information and an instruction for executing screen sharing with the first terminal device, wherein the address information is used by the first terminal device in the second wireless network.

4. The apparatus of claim 1 , wherein

the memory stores address information used by each of the terminal devices in the second wireless network; and

the processor further:

establishes, using an address information assigned to the first terminal device, a connection with the first terminal device via the second wireless network;

transmits, to the first terminal device, an instruction that causes the first terminal device to receive the display information displayed on the second terminal device; and

transmits, via the first wireless network and to the second terminal device, the address information of the first terminal device and an instruction that causes the second terminal device to execute screen sharing with the first terminal device.

5. A method comprising:

delivering, via an access point and over a first wireless network, display information to terminal devices on the first wireless network;

obtaining, from the access point, connection status information that represents a connection status between each of the terminal devices and the first wireless network via the access point,

detecting, using the connection status information and among the terminal devices, a first terminal device whose connection to the first wireless network via the access point is disconnected and a second terminal device whose connection to the first wireless network via the access point is connected; and

transmitting, to the second terminal device over the first wireless network, an instruction to:

transmit, without going through the access point and from the second terminal device to the first terminal device over a second wireless network that is different from the first network, display information displayed on the second terminal device,

wherein the second terminal device receives, over the first wireless network, the display information displayed on the second terminal device; and

transmitting, from the second terminal device to the first terminal device and in response to the instruction, the display information displayed on the second terminal device over the second wireless network.

6. A non-transitory, computer-readable recording medium having stored therein a program that causes a computer to execute a process comprising:

delivering, via an access point and over a first wireless network, display information to terminal devices on the first wireless network;

obtaining, from the access point, connection status information that represents a connection status between each of the terminal devices and the first wireless network via the access point,

detecting, using the connection status information and among the terminal devices, a first terminal device whose connection to the first wireless network via the access point is disconnected and a second terminal device whose connection to the first wireless network via the access point is connected; and

transmitting, to the second terminal device over the first wireless network, an instruction to:

transmit, without going through the access point and from the second terminal device to the first terminal device over a second wireless network that is different from the first wireless network, display information displayed on the second terminal device,

wherein the second terminal device receives, over the first wireless network, the display information displayed on the second terminal device.

7. The apparatus of claim 1 , wherein

the memory stores position information of each of the terminal devices, and

the processor further detects, among the terminal devices, a terminal device whose connection to the first wireless network via the access point is connected and position is closest to a position of the first terminal device as the second terminal device.

8. The method of claim 5 , wherein the detecting of the first terminal device and the second terminal device comprises:

detecting, among the terminal devices, a terminal device whose connection to the first wireless network via the access point is connected and whose position is closest to a position of the first terminal device as the second terminal device.

9. The non-transitory computer-readable recording medium of claim 6 , wherein the detecting of the first terminal device and the second terminal device comprises:

detecting, among the terminal devices, a terminal device whose connection to the first wireless network via the access point is connected and whose position is closest to a position of the first terminal device as the second terminal device.
