Embodiment shall fall within the protection scope of the present invention.
In order to reduce the probability for network identity conflict occur, an embodiment of the present invention provides a kind of detection network identity conflicts
Method, apparatus and radio reception device.First, it is provided for the embodiments of the invention a kind of side of detection network identity conflict
Method is introduced.
A kind of executive agent of the method for detection network identity conflict that the embodiment of the present invention is provided can be ZigBee
The radio reception device of network, radio reception device are used for the data that receiving terminal apparatus is collected.The wireless of ZigBee-network connects
Enter that equipment is divided into the first radio reception device that ZigBee-network has been established and request is established the second of ZigBee-network and wirelessly connect
Enter equipment, the detection of network identity conflict is detected whether with first wirelessly before the second radio reception device reaches the standard grade work
Access device needs real by interaction there are network identity conflict between the first radio reception device and the second radio reception device
The method for the detection network identity conflict that the existing embodiment of the present invention is provided.Realize a kind of detection that the embodiment of the present invention is provided
The mode of the method for network identity conflict can be in the software, hardware circuit and logic circuit being set in executive agent
At least one mode.
In the following, the method for being provided for the embodiments of the invention detection network identity conflict is introduced, as shown in Figure 1,
For distinguish two radio reception devices, the present embodiment with executive agent be the first radio reception device, but it is to be understood that, this
First, second in embodiment is intended merely to distinguish two radio reception devices, is not the restriction to radio reception device.This
A kind of method for detection network identity conflict that inventive embodiments are provided, may include steps of.
S101 receives the beacon request message that the second radio reception device broadcast of ZigBee-network is established in request.
Second radio reception device after start-up, needs to establish ZigBee-network, at this point, can be wanted according to series of protocols
It asks and works, then broadcast Beacon Request messages, with the state of the other equipment radio reception device in informing network,
The second radio reception device is carried in Beacon Request messages under normal conditions and (ZigBee hereinafter, is established into request
Second radio reception device of network is denoted as Z2) network identity, address information etc., entrained network identity can be Z2
PAN ID (Personal Area Network Identifier, personal area network's mark), or system is divided at random
The network identity matched can also be the network identity of manual configuration, be used for the wireless access of one ZigBee-network of unique mark
Equipment.
S102, when according to the network identity carried in beacon request message, detecting the presence of network identity conflict, to the
Two radio reception devices reply beacon response message, and start the first timer and count duration.
First radio reception device (hereinafter, is denoted as Z1) by the first radio reception device, and Z1 normal works are receiving
After the Beacon Request messages that Z2 is sent, it can be come true according to the network identity carried in Beacon Request messages
It is fixed whether to detect network identity conflict, if the network identity of the network identity and Z1 carried in Beacon Request messages
It is identical, then it is assumed that there are network identity conflicts, if the network of the network identity and Z1 carried in Beacon Request messages
Mark is different, then it is assumed that network identity conflict is not present.
No matter whether Z1 detects network identity conflict, Beacon Response messages, the Beacon can be replied to Z2
The network identity (such as macPAN ID) that Z1 is carried in Response messages, for making Z2 judge whether that network identity rushes
It is prominent that foundation is provided.After Z2 receives Beacon Response messages, if detecting the presence of network identity conflict, rushed starting
Prominent settlement mechanism, carries out clash handle.
If Z1 detects the presence of network identity conflict, first can be started while replying Beacon Response messages
Timer counts duration, for counting after receiving a Beacon Request message, it is contemplated that receive next
The time interval of Beacon Request messages.
Optionally, following steps can also be performed in the method for the detection network identity conflict that the embodiment of the present invention is provided：
If the first radio reception device receives the beacon request message of the second radio reception device broadcast again, by the
One timer is reset.
If Z1 is received again by the Beacon Request messages of Z2, illustrate that the transmission line between Z1 and Z2 is normal,
Packet loss phenomenon can not occur with normal transmission message, at this point, Z1 just resets the first timer, be detected again and Z2 in Z1
Between there are when network identity conflict, restart using first timer count duration.
S103 if the duration of the first timer statistics is more than default waiting time, and does not receive second and wirelessly connects again
Enter the beacon request message of device broadcasts, then carries the first radio reception device itself net to the transmission of the second radio reception device
The beacon message of network mark.
Default waiting time is preset fixed value, and the intervals Beacon and network delay to be arranged according to Z2 calculate
The duration arrived presets Beacon interval of the waiting time more than Z2 settings, is to be expected to receive Beacon Request next time
The time of message does not receive what Z2 was broadcasted again also if the duration of the first timer statistics is more than default waiting time
Beacon Request messages, then it is assumed that Z1 is not because packet loss receives the Beacon Request messages of Z2 broadcast, at this point, being
It prevents the influence of packet loss, confirm whether network identity conflict has avoided, Z1 actively can send Beacon messages to Z2, should
The network identity of Z1 is carried in Beacon messages so that Z2 takes after receiving Beacon messages according in Beacon messages
The network identity of band detects network identity conflict.
Z1 can also delete the first timer after sending Beacon messages to Z2, discharge occupied by the first timer
Memory source.
Z1 is after having sent Beacon messages, in spite of the response message for receiving Z2 replies, is all not necessarily to processing, subsequently
Stop sending Beacon messages, restores normal operating conditions.
Optionally, the first radio reception device Z1 sends to the second radio reception device Z2 and carries what own net identified
Beacon message is specifically as follows：
Clear channel assessment (CCA) threshold value is reduced, the first radio reception device is carried to the transmission of the second radio reception device
The beacon message of network identity.
It may occur due to cause due to long transmission distance, the data-signal with transmission are weak etc. packet loss phenomenon,
In order to avoid the packet loss caused by the above problem, CCA (Clear Channel can be reduced when sending Beacon messages
Assessment, clear channel assessment (CCA)) threshold value, it ensure that the remote of data is transmitted, reduces the dry of other data-signals
It disturbs.
The reduction of CCA thresholdings can reduce the 1-2 order of magnitude according to actual conditions, for example, CCA threshold values are defaulted as N, that
CCA threshold values are reduced to N-1 (or N-2) before sending Beacon messages, CCA threshold values reduce only empty in detection
When mouth, default value is just reverted to after having sent Beacon messages.
Using the present embodiment, if the duration that Z1 is counted in the first timer is more than default waiting time, and do not connect again
Receive Beacon Request messages, then it is assumed that Z1 is not because packet loss receives Beacon Request messages, therefore, Z1 again
A Beacon message can be actively sent to Z2, so that Z2 detects network mark according to the network identity carried in Beacon messages
Conflict is known, in this way, being effectively reduced the probability because of network identity conflict caused by packet loss.
As shown in Fig. 2, executive agent is the second radio reception device, a kind of detection network that the embodiment of the present invention is provided
The method for identifying conflict, may include steps of.
S201 broadcasts beacon request message, and starts the second timer and third timer statistics duration.
Second radio reception device can broadcast Beacon Request messages when ZigBee-network is established in request, other
Radio reception device can receive the Beacon Request messages, and respond the Beacon Request messages, Z2 is wide
When broadcasting first Beacon Request message, the second timer and third timer statistics duration, the second timer can be started
The when a length of time interval for waiting for Beacon Response messages counted with third timer, the second timer counted
Duration be often below the pre-set intervals Beacon Z2, the duration that third timer is counted is often below maximum when waiting for
It is long.
In order to preferably explain maximum waiting time, the meaning of characterization can be introduced in step S203.
S202, if the duration of the second timer statistics is more than actual beacon interval, and according to the beacon response report received
The network identity carried in text detects there is no network identity conflict or does not receive beacon response message, then again wide
Beacon request report is broadcast, and the second timer is reset.
If the duration of the second timer statistics is more than the default intervals Beacon, and can't detect network identity conflict or
Person does not receive any Beacon Response messages, then Z2 thinks the Beacon Request message droppings of last broadcast,
Or receive the Beacon Response message droppings that the radio reception device of the Beacon Request messages is responded, then Z2
Beacon Request messages can be re-broadcast, and the second timer is reset, are executed repeatedly with this repeatedly, repeated broadcast
The number of Beacon Request messages should not be excessive, can largely occupy network transmission resource, therefore, under normal conditions can be with
It is set as re-broadcasting Beacon Request messages twice again.
Optionally, beacon request report is re-broadcast, is specifically as follows：
Clear channel assessment (CCA) threshold value is reduced, beacon request message is re-broadcast.
It may occur due to cause due to long transmission distance, the data-signal with transmission are weak etc. packet loss phenomenon,
In order to avoid the packet loss caused by the above problem, CCA (Clear Channel can be reduced when sending Beacon messages
Assessment, clear channel assessment (CCA)) threshold value, it ensure that the remote of data is transmitted, reduces the dry of other data-signals
It disturbs.
The reduction of CCA thresholdings can reduce the 1-2 order of magnitude according to actual conditions, for example, CCA threshold values are defaulted as N, that
CCA threshold values are reduced to N-1 (or N-2) before sending Beacon messages, CCA threshold values reduce only empty in detection
When mouth, default value is just reverted to after having sent Beacon messages.
Optionally, the method for the detection network identity conflict that the embodiment of the present invention is provided, can also be performed following steps：
Judge whether the number for broadcasting beacon request message reaches preset times；
If reaching, the second timer is deleted.
Preset times are the number of pre-set Z2 repeated broadcasts Beacon Request messages, are arranged under normal conditions
It is 3 times, if Z2 repeated broadcast Beacon Request messages reach the preset times, deletes the second timer, release the
The occupied memory source of two timers.
S203, if the duration of third timer statistics is less than maximum waiting time, and according to the beacon response report received
The network identity that is carried in text or according to the network identity carried in the beacon message received, detects the presence of network mark
Know conflict, then carries out clash handle.
If the duration of third timer statistics is less than maximum waiting time, and Z2 detects network identity conflict, just
Start clash handle program, Z2 takes Mechanism of Conflict Among, carries out the clash handles such as offline, change network identity.Maximum waits for
After Shi Changwei Z2 repeatedly broadcast Beacon Request messages according to preset times, Z2 can receive other wireless access
Equipment (it may be multiple to receive the radio reception device of Beacon Request messages, for ease of illustrating, the present embodiment
In illustrated by taking Z1 as an example) first Beacon of the last one Beacon Response message distance broadcast for replying
The largest interval of Request messages, by taking 3 Beacon Request messages of the most repeated broadcasts of Z2 as an example, under normal circumstances, Z1
The last one Beacon Request message is at most received within the time of T02*3+T00, between wherein T02 is default Beacon
Every T00 is that default waiting time, (after Z2 broadcasts a Beacon Request message, Z1 can receive the Beacon
The stand-by period of Request messages), in this way, Z2 at most receives the last one Beacon within the time of T02*3+T00*2
Response messages, so, maximum waiting time could be provided as T02*3+T00*2, if the duration of third timer statistics
Maximum waiting time is had exceeded, network identity conflict is still not detected, it is determined that for Z1 and Z2 without network identity conflict, Z2 can be with
Normally establish ZigBee-network.
Optionally, the method for the detection network identity conflict that the embodiment of the present invention is provided, can also be performed following steps：
If the duration of third timer statistics reaches maximum waiting time, third timer is deleted.
If the duration of third timer statistics reaches maximum waiting time, Z2 can normally establish ZigBee-network, then
Third timer can be deleted, the occupied memory source of third timer is discharged, without doing other processing.
Using the present embodiment, Z2 broadcasts Beacon Request messages, and starts the second timer and third timer system
Timing is long；If the duration of the second timer statistics of Z2 is more than actual beacon interval, and Z2 is according to the Beacon received
The network identity carried in Response messages detects there is no network identity conflict or does not receive Beacon
Response messages, then it is assumed that other radio reception devices are not because packet loss receives Beacon Request messages or Z2
Because packet loss does not receive Beacon Response messages, therefore, Z2 re-broadcasts Beacon Request messages.Pass through weight
New broadcast Beacon Request messages can be effectively reduced other radio reception devices because packet loss does not receive
The probability that the case where Beacon Request messages occurs, and by re-broadcasting Beacon Request messages, other nothings
Line access device can reply Beacon Response messages again, also be effectively reduced Z2 because packet loss does not receive
The probability that the case where Beacon Response messages occurs.Therefore, reduce because network identity conflict is several caused by packet loss
Rate.
Also, if the duration of the third timer statistics of Z2 is less than maximum waiting time, and Z2 is according to receiving
The network identity that is carried in Beacon Response messages detects the presence of network identity conflict or according to receiving
The network identity carried in Beacon messages detects the presence of network identity conflict, then carries out clash handle.By the way that third is arranged
Timer enhances the validity of the identification to network identity conflict.
In order to make it easy to understand, with reference to specific example from the friendship of the first radio reception device and the second radio reception device
Mutually, be provided for the embodiments of the invention it is a kind of detection network identity conflict method be introduced, as shown in figure 3, interacting
Journey may include steps of.
S301, the second radio reception device Z2 broadcast Beacon Request messages, and start the second timer T2 and the
Three timer T0 count duration.
After S302, the first radio reception device Z1 receive the Beacon Request messages of Z2, according to Beacon
Request messages detect whether that there are network identity conflicts.
S303 replys Beacon Response messages if Z1 is detected there is no network identity conflict.
S304 replys Beacon Response messages if Z1 detects the presence of network identity conflict, and starts the first meter
When device T count duration.
The first timer T is reset when Z1 is received again by the Beacon Request messages of Z2, resetting thinks highly of timing
New zero, the effect of T are timing after receiving first Beacon Request message, it is contemplated that receive second Beacon
The time interval of Request messages.
S305, after the duration of T2 statistics is more than the default intervals Beacon T02, if Z2 receives multiple Beacon
Response messages still receive there is no any network identity conflict or not any Beacon Response messages, then
Execute S306.
S306, Z2 reduce CCA threshold values, re-broadcast Beacon Request messages, reset T2.
The maximum times of Z2 repeated broadcast Beacon Request messages are 3 times, and T2 is deleted after reaching 3 times maximum,
As the second timer T0=T02*3+T00*2 of Z2, T0 is deleted, wherein T02 is the default intervals Beacon, and T00 is default etc.
Wait for duration.
S307, if within time of the duration more than T00 of the first timer T statistics of Z1, Z1 is not received again by
The Beacon Request messages of Z2 broadcast, then execute S308.
S308 reduces CCA threshold values, and one Beacon message of encapsulation is actively sent to Z2, while deleting first timer
T。
After Z1 sends Beacon messages, it is all not necessarily to processing in spite of response is received, it is follow-up to stop sending Beacon
Message restores normal operating conditions.
S309, if after Z1 sends Beacon messages, Z2 detects the presence of network identity conflict, and the second timing of Z2
The duration of device T0 statistics is less than TL, and Z2 starts clash handle program, carries out clash handle.
Wherein, TL is systemic presupposition value, and TL meets under normal conditions：T02*3+T00*2>TL>T02*3+T00, i.e., in TL
Period within the Z2 that has just worked need to start Mechanism of Conflict Among and illustrate that Z2 is to be at originally if having exceeded TL
Normal work, without processing.
In the present solution, Z2 broadcasts Beacon Request messages, and when the second timer of startup and third timer statistics
It is long；If Z1 receives Beacon Request messages, and is examined according to the network identity carried in Beacon Request messages
It measures that there are network identity conflicts, then replys Beacon Response messages to Z2, and start the first timer and count duration；
If the duration of the second timer statistics is more than actual beacon interval, and Z2 is according to the Beacon Response messages received
The network identity of middle carrying detects there is no network identity conflict or does not receive Beacon Response messages, then weighs
New broadcast Beacon Request messages；If the duration of the first timer statistics is more than default waiting time, and Z1 is not again
Beacon Request messages are received, then send the Beacon messages for carrying network identity to Z2, and delete the first timing
Device；If the duration of third timer statistics is less than maximum waiting time, and Z2 is reported according to the Beacon Response received
The network identity carried in text detects the presence of network identity conflict or according to the net carried in the Beacon messages received
Network label detection then carries out clash handle to there are network identity conflicts.The duration that Z2 is counted in the second timer is more than default
Beacon interval, and detect that there is no network marks according to the network identity carried in the Beacon Response messages received
Know conflict or do not receive Beacon Response messages, then it is assumed that Z1 is not because packet loss receives Beacon Request
Message or Z2 be not because packet loss receives Beacon Response messages, and therefore, Z2 retransmits Beacon Request
Message；And the duration that Z1 is counted in the first timer is more than default waiting time, and does not receive Beacon again
Request messages, then it is assumed that Z1 is not because packet loss receives Beacon Request messages again, and therefore, Z1 can actively be sent
One Beacon message, so that Z2 detects network identity conflict, in this way, having according to the network identity carried in Beacon messages
Effect reduces the probability because of network identity conflict caused by packet loss.
Corresponding to above method embodiment, an embodiment of the present invention provides a kind of devices of detection network identity conflict, answer
