Node scheduling method and system and device
First Claim
1. A node scheduling method comprising:
- configuring, for each node in a network, a working period matched with a performance indicator of the node, wherein a duration of the working period of each node is an integer multiple of duration of a super frame corresponding to a beacon frame in the network; and
sending, to each of the nodes, an updated beacon frame that comprises information about the working period, so that each nodea) acquires the information about the working period from the updated beacon frame,b) receives a working beacon frame that is a beacon frame broadcast in the network at a start moment of the working period,c) establishes a super frame corresponding to the working beacon frame until the working period ends, andd) then repeats receiving the working beacon frame and establishing the super frame corresponding to the working beacon frame until the updated beacon frame is received again,obtaining, according to the working period of each node in the network, at least one node that can receive the beacon frame for broadcasting,configuring on each node a guaranteed timeslot (GTS) field in the beacon frame according to a GTS request in a previous super frame, wherein the GTS field identifies a node in the network in a contention free period of the super frame corresponding to the beacon frame; and
sending the working beacon frame to the obtained node in the network.

Abstract
Embodiments of the present invention disclose a node scheduling method, where the method includes: configuring, for a node, a working period matched with a performance indicator of the node, where duration of the working period is an integer multiple of duration of a super frame, and the super frame is a super frame corresponding to a beacon frame in a network in which the node is located; and sending, to the node, an updated beacon frame that includes information about the working period, so that the node acquires the information about the working period from the updated beacon frame, receives a working beacon frame, establishes a super frame corresponding to the working beacon frame until the working period ends, and then repeats the receiving a working beacon frame and establishing a super frame corresponding to the working beacon frame until the updated beacon frame is received again.

7. A network device for scheduling nodes in a network, the network device comprising:
-
a processor configured to provide for each node in the network, a) a working period matched with a performance indicator of the node, wherein a duration of the working period is an integer multiple of a duration of a super frame corresponding to a working beacon frame for broadcasting in the network at a start moment of the working period; b) at least one node, according to the working period for the node, that can receive the working beacon frame; and c) a guaranteed timeslot (GTS) field in the working beacon frame according to a GTS request in a previous super frame, wherein the GTS field identifies a node in the network in a contention free period of the super frame corresponding to the working beacon frame; d) an updated beacon frame for broadcasting to nodes in the network that comprises information about the working period, allowing each node to; i. acquire the information about the working period from the updated beacon frame, ii. receive a working beacon frame that is a beacon frame broadcast in the network at a start moment of the working period, iii. establish a super frame corresponding to the working beacon frame until the working period ends, and iv. repeatedly receive the working beacon frame and establishing the super frame corresponding to the working beacon frame until the updated beacon frame is received again; and a transmitter configured to broadcast the working and updated beacon frames. - View Dependent Claims (8, 9, 10, 11, 12)

13. A node device in a network, the node device comprising:
-
a receiver configured to receive from a coordinator (a) a working beacon frame sent by the coordinator at a start moment of a working period (b) an updated beacon frame that comprises information about the working period, wherein the working period is matched with a performance indicator of the node device, a duration of the working period is an integer multiple of a duration of a super frame corresponding to a beacon frame in the network and (c) when the working period ends, repeat receiving the working beacon frame until the updated beacon frame is received again; a processor configured to acquire the information about the working period from the updated beacon frame and establish a super frame corresponding to the working beacon frame; wherein the information comprises; (a) an updated quantity of node devices in the network, (b) a beacon order indicating a duration of a super frame corresponding to the updated beacon frame, and (c) a period allocation list comprising, for each node device in the network, an address of a node device and the duration of the super frame for the node. - View Dependent Claims (14, 15, 16, 17)
