It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Example 1
This embodiment provides a control instruction sending method, which may be applied to a router or a gateway side, and fig. 1 is a flowchart of the control instruction sending method provided in embodiment 1 of the present invention, as shown in fig. 1, where the method includes the following steps:
step 101: inviting the controlled device to join the NAN group;
step 102: and sending a control instruction to the controlled device joining the NAN group by using the NAN within the discovery time window of the NAN.
Further, in a case that the main control terminal is a mobile terminal, the position of the main control terminal from the controlled terminal is not fixed, so that the interval of the discovery time window needs to be dynamically adjusted, based on which, on the basis of the above steps 101 and 102, the method may further include: the method includes the steps of prolonging the interval of a discovery time window and informing other non-supervisor members in a NAN group of the master device when the fact that the distance between the master device and the supervisor device (for example, a gateway device or a router) exceeds a preset distance is detected, wherein only the controlled device is informed when the master device does not join the NAN group, and in addition, when the fact that the distance between the master device and the supervisor device is recovered to be within the preset distance is detected, the interval of the discovery time window is shortened and the shortened interval of the time window is informed to the other non-supervisor members in the NAN group.
In this embodiment, the master device may communicate with the controlled device as a member of the NAN group, or may communicate with the controlled device through a router or a gateway without joining the NAN group, and the inviting the controlled device to join the NAN group may specifically include: receiving equipment information of controlled equipment, and sending a NAN group identification to the controlled equipment according to the information to invite the controlled equipment to join the NAN group; or sending a NAN group identifier to the master control device to invite the master control device to join the NAN group, so that the master control device invites the controlled device to join the NAN group, wherein the device information at least includes address information of the device.
Before 102 before the step 101 is performed, the present embodiment further includes a process of establishing a NAN group, and based on this, the method may further include: before inviting the controlled equipment to join the NAN group, establishing the NAN group by the identity of the supervisor; and setting an identifier of the NAN group, wherein the identifier represents that the NAN group is a permanent group of the home domain, and the identifier is used for indicating the controlled device to join the NAN network by using the non-master device and/or indicating that the controlled device does not use a collision detection mechanism before sending the message in the discovery time window.
The NAN communication method needs to use a collision detection mechanism to avoid message collision, and in addition, outside the time window, the supervisor needs to send a service discovery beacon to enable other devices to discover the NAN network, but these two processes are undoubtedly not needed for the controlled device belonging to the information receiving end in most of the time in the home environment, so in this embodiment, in the process of communicating with the master control terminal or the controlled terminal, in the discovery time window, the collision detection mechanism is not used, and the discovery beacon is not sent outside the discovery time window.

the router or the gateway as a given Master creates a NAN Cluster (Neighbor Aware Network Cluster), sets a Cluster ID (identifier), the ID represents that the Cluster is a home domain permanent Cluster, and does not send a discovery Beacon frame in a discovery time window interval.
The mobile device obtains information of the home appliance device through NFC (Near Field Communication) or code scanning, so as to join the home appliance device to the NAN Cluster of the home.
The method comprises the steps that WLAN connection is established between the mobile equipment and a router or a gateway, meanwhile, a home appliance receiver needing to be added into NAN Cluster is started for a period of time, the mobile equipment sends information of the home appliance to the router or the gateway through the WLAN in the period of time, and after the router or the gateway receives a message, a command (the command carries a Cluster ID) for inviting the home appliance to be added into the NAN Cluster is sent to the home appliance.
After receiving the invitation, the household appliance judges that the Cluster is a permanent Cluster of the family domain through the Cluster ID, and then adds the permanent Cluster into the Cluster by a non-master identity, and sets the permanent Cluster in a discovery time window without using a collision avoidance mechanism to send messages.
The mobile device uses the WLAN to send commands to control the home device to the router or gateway.
If the router or the gateway is in the NAN discovery time window at the moment, directly transmitting the command to the household appliance through the NAN; if not, the command is stored and forwarded when the next time window is up.
If the command received by the home device, e.g. a television, is to turn on a high traffic service, e.g. video transmission, etc., a WLAN connection to a router or gateway or a P2P (Peer-to-Peer) connection to a mobile device is created.
When the router or gateway detects that the mobile device is away from home (which may be implemented by the distance between the mobile device and the home device), the home device is notified to delay the interval of the discovery time window. When the router or gateway detects that the mobile device has come home, the home device is notified to shorten the interval of the discovery time window.

The mobile equipment sends a command of inviting to join the NAN Cluster to the household electrical appliance equipment in modes of NFC or code scanning and the like, the household electrical appliance equipment judges that the Cluster is a permanent Cluster of a family domain through a Cluster ID, then the Cluster is joined to the Cluster in a non-master identity, the Cluster is set in a discovery time window, and a conflict detection mechanism is not used for sending messages.
The mobile device sends a command to control the home device to the home device using the NAN.
If the command received by the home device, e.g., television, is to turn on a high traffic service, such as video transmission, etc., a WLAN connection to a router or gateway or a P2P connection to the mobile device is created.
When the router or gateway detects that the mobile device has left home, the home device is notified to delay the interval of the discovery time window.
After the mobile equipment goes home and establishes WLAN connection with the router or the gateway, if the router or the gateway is in a NAN discovery time window at the moment, informing all equipment through the NAN, wherein the time window interval is shortened by the household appliance equipment and the mobile equipment, and the time of the next discovery time window is shortened by the household appliance equipment and the mobile equipment; if not, the mobile device is informed of the start time of the next time window through the WLAN, and after the start of the next time window, all devices, including the home device and the mobile device, are informed to shorten the time window interval.
