Specific embodiment
In order to solve the problems, such as to interfere with each other and consume a large amount of electric energy of system between node existing in the prior art, the present invention
It is proposed a kind of wireless telecommunications management method and device, this method are as follows: when receiving the Beacon packet that host node is sent from node,
Preset initial value is set as from node by the slot index of itself；From node according to total number of time slots in Beacon packet, each
The number of the time span of time slot, the ratio and retained business time slot of sending time slots and reception time slot generates the time slot from node
Configuration parameter；It is directed to from node according to time slot configuration parameter and carries out slot count since the slot index of node, and entered and stop
Dormancy state.
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
Refering to shown in Fig. 2 and Fig. 3, in wireless telecommunication system, host node immediately enters working condition after powering on, and is directed to
Slot index carries out slot count.Host node controls content according to base slot, sends broadcast in the first time slot of each time frame
It wraps (Beacon packet).Wherein, Beacon packet include at least total number of time slots, the time span of each time slot, sending time slots with connect
The ratio of time receiving gap and the number of retained business time slot.Here the ratio of sending time slots and reception time slot refers to from node
Sending time slots and receive time slot ratio.
In addition, attribute of the host node according to slave node number, node in system, that is, send from node and receive from node
And in the specific adjustable Beacon packet of business demand content specific value, and regularly send the Beacon packet and notify institute
Have from the time slot configuration parameter of node updates oneself and meets business demand to promote bandwidth availability ratio.
For example, the slave node in the network is less, and host node and it is larger from the single communication data amount between node when, it is main
Node can reduce time slot total number, increase the length of single time slot, when allowing each data transmission that can possess enough as far as possible
Between, and the ratio for receiving time slot and sending time slots is adjusted, improve communication efficiency.
In another example when more from node in network, and when single communication data amount is smaller, host node can increase time slot
Total number reduces the length of single time slot, while guaranteeing that data are sent, when guarantee is each can to obtain enough from node
Gap goes to send, and also reduces respectively from the interference between node.
Therefore, host node can be accomplished to the full extent using bandwidth, and increase by adjusting the content in Beacon packet
Dormancy time, reduction power consumption from node.
After powering on from node, it is in reception state.
Step 200: when receiving the Beacon packet that host node is sent from node, being set from node by the slot index of itself
For preset initial value.
After the Beacon packet that node receives that host node is sent, time synchronization is carried out, the slot index of itself is set as
1, the slot index of host node is also 1 at this time.
Step 210: from node according to total number of time slots in Beacon packet, the time span of each time slot, sending time slots
The time slot configuration parameter from node is generated with the number of the ratio and retained business time slot that receive time slot.
When from node according to total number of time slots in Beacon packet, the time span of each time slot, sending time slots and reception
The ratio of gap and the number of retained business time slot generate the time slot configuration parameter from node, i.e. time slot vector table, this time slot to
Scale is synchronous with the holding of the time slot vector table of host node, i.e., when being sending time slots from node, host node is to receive time slot, and two
Person is to carry out minislot parameter configuration according to Beacon packet content, and both default time slot 1 is that host node sends Beacon
The time slot of packet and the time slot that Beacon packet is received from node.
Step 220: it is directed to from node according to time slot configuration parameter and carries out slot count since the slot index of node, and
Into dormant state.
Slot count cycle period is generated from node according to time slot configuration parameter, uses institute for from the slot index of node
It states slot count cycle period to start to carry out slot count, and regardless of whether maintains slot count always in a dormant state.
In addition, slot count is carried out since the slot index of node being directed to from node according to time slot configuration parameter, and
Into after dormant state, respectively waken up from node according to the time slot vector table from node, i.e. time slot configuration parameter and slot index
Just in the slave node of suspend mode, received or sent data, other times are then in system dormant state, thus ensure that from
The low-power consumption of node, host node is then in corresponding working condition according to the time slot vector table of host node always at this time, does not enter
Suspend mode.
Therefore, may have from node there are three types of state, i.e., dormant state, send data mode and receive data mode.
When needing to send business datum from node, from node according to time slot configuration parameter, and it is based on slot count knot
The current time slots label that fruit determines, determines the slot attributes of current time slots.
Wherein, slot attributes are for characterizing time slot type.
When determining that current time slots are sending time slots based on slot attributes from node, terminate dormant state, initiates channel quality
Detection.
Specifically, respectively can according to physical address (Media Access Control, MAC) unique in system from node
The channel quality detection of location progress random time.
Channel quality detection is obtained from node as a result, and determining channel quality detection result less than or equal to preset thresholding
When, business datum is sent in sending time slots.
Here why need to need to detect channel quality before sending business datum, be because being sent out from node
It send data to use competition transmission mechanism, i.e., can only there is one to send data from node in a sending time slots.
Therefore, when needing to send data from node for one, it is necessary first to according to time slot configuration parameter and it is current when
Whether the judgement of gap label is currently sending time slots, if so, initiating channel quality detection, further judges testing result from node
Whether preset thresholding is less than or equal to, if so, sending the data for needing to send in currently transmitted time slot.Otherwise, if from node
It determines that current time slots are not sending time slots based on slot attributes, then continues to dormant state, reach sending time slots until waiting
When, then terminate dormant state, initiate channel quality detection.And determine that channel quality detection result is greater than preset door from node
In limited time, business datum is not sent, keeps out of the way process into data are sent, and restore dormant state.So it then ensure that from section
Data between point send uniqueness, reduce from the interference between node.
From node according to time slot configuration parameter, and based on the current time slots label that slot count result determines, determination is worked as
The slot attributes of preceding time slot when judging current time slots based on slot attributes from node to receive time slot, terminate dormant state, and right
Business datum reception state is detected, and is determined when receiving business datum, is handled business datum, and processing terminate
Afterwards, restore dormant state.
Therefore, from node can timing wake-up system carry out reception data, and restore suspend mode after reception, ensure that from
The low-power consumption of node.
For the retained business time slot at hour hands end, be allocated according to each uniquely tagged from node, i.e., it is default
Retained business allocation plan, from node setting for send the label of the time slot of retained business data do not need competition go to send
Data guarantee there are unique sending time slots within the time of business need.It, completely can be with if there is no a retained business demand certainly
Remove the presence of the reserved time slot.
Specifically, from node according to time slot configuration parameter, and the current time slots label determining based on slot count result,
Determine the slot attributes of current time slots.When being based on slot attributes from node and judging current time slots for reserved time slot, further basis
Preset retained business allocation plan, when reaching the corresponding time slot for being used to send retained business data preset from node, hair
Send retained business data.
