Abstract

Embodiments of the present invention provide a node control method, a network controller, and a network system. The node control method includes: constructing a wake-up frame, where the wake-up frame includes wake-up indication information of a node to be woken up; and sending, in an inactive period of a superframe structure, the wake-up frame according to preset sending time, so that a node that obtains, by listening, the wake-up frame performs data exchange with a network controller when it is determined, according to the wake-up indication information, that the node that obtains, by listening, the wake-up frame is the node to be woken up. A wake-up frame may be sent in an inactive period of a superframe structure to implement data communication between a node and a network controller, which increases a length of the superframe structure and can meet a requirement for data uploading by the node.

Claims

1. A node control method, comprising:

constructing a wake-up frame comprising wake-up indication information of a node to be woken up; and

sending, in an inactive period of a superframe structure, the wake-up frame according to preset sending time, so that a node that obtains, by listening, the wake-up frame performs data exchange with a network controller when it is determined, according to the wake-up indication information, that the node that obtains, by listening, the wake-up frame is the node to be woken up.

2. The node control method according to claim 1, wherein the wake-up indication information comprises:

a node address of the node to be woken up;

or

a broadcast wake-up address, and the broadcast wake-up address is indication information used to wake up one type of node or all nodes.

3. The node control method according to claim 1, wherein the number of the nodes to be woken up is one or more.

4. The node control method according to claim 1, wherein the number of the wake-up frames is one or more.

5. The node control method according to claim 1, wherein the wake-up frame comprises an address of the network controller.

6. The node control method according to claim 1, wherein constructing a wake-up frame comprises:

constructing the wake-up frame according to preset listening time of the node to be woken up.

7. A node control method, comprising:

listening, at preset listening time in an inactive period of a superframe structure, for a wake-up frame sent by a network controller, wherein the wake-up frame comprises wake-up indication information of a node to be woken up; and

performing data exchange with the network controller when it is determined, according to the wake-up indication information, that a node is the node to be woken up.

8. The node control method according to claim 7, further comprising:

controlling the node to enter a sleep state when the node is not the node to be woken up.

9. A network controller, comprising:

a wake-up frame constructing module, configured to construct a wake-up frame comprising wake-up indication information of a node to be woken up; and

a wake-up frame sending module, configured to send, in an inactive period of a superframe structure, the wake-up frame according to preset sending time, so that a node that obtains, by listening, the wake-up frame performs data exchange with a network controller when it is determined, according to the wake-up indication information, that the node that obtains, by listening, the wake-up frame is the node to be woken up.

10. The network controller according to claim 9, wherein the wake-up indication information comprises:

a node address of the node to be woken up;

or

a broadcast wake-up address, and the broadcast wake-up address is indication information used to wake up one type of node or all nodes.

11. The network controller according to claim 9, wherein:

the number of the nodes to be woken up is one or more; and

the number of the wake-up frames is one or more.

12. The network controller according to claim 9, wherein the wake-up frame comprises an address of the network controller.

13. The network controller according to claim 9, wherein the wake-up frame constructing module is configured to construct a wake-up frame according to preset listening time of the node to be woken up.
