Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
In order to solve the problems, such as prior art, the present invention each provides a kind of correlating method from the angle of AC and AP
And device.
First below the present invention is illustrated from a kind of correlating method that the angle of AC is provided.
Referring to Fig. 1, the flow chart that a kind of correlating method that the embodiment of the present invention is provided is shown in figure.As shown in figure 1,
The method may include steps of：
S101, obtains request message that AP is broadcasted, existence for obtaining the corresponding pre- roaming list items of the AP, its
In, the request message includes the identification information of the AP.
It should be noted that if the corresponding pre- roaming list items of the AP are there is in AC, the source of the pre- roaming list item can
To there is two kinds of situations.In the case of one kind, the pre- roaming list item be AC from the AP successful associations after generate；Another kind of feelings
Under condition, the pre- roaming list item is that another AC belonged to AC in same predetermined AC groups is generated and sent after with the AP successful associations
To the AC.
It is easily understood that when AC obtains existence that AP is broadcasted, for obtaining the corresponding pre- roaming list items of the AP
Request message after, AC can go to check whether therein is stored with the corresponding pre- roaming list items of the AP.
S102, according to the identification information of the AP, determines the pre- roaming list item that itself whether is stored with；If it is, performing
S103。
It should be noted that the corresponding pre- roaming list items of the AP can be the pre- roaming table of the identification information for including the AP
.Specifically, the identification information of the AP can be the AP mac address information and/or Serial-ID (i.e. the serial number of AP, its
A certain AP can be uniquely identified).In addition, the AC memory storages, the AP it is corresponding it is pre- roaming list item in can also include AP-ID
Number (because simultaneously AC may be associated with multiple AP, in order to make a distinction to the plurality of AP, AC can be to associate with itself
Each AP determines one uniquely No. AP-ID, and No. AP-ID can determine according to default coding rule).
For arbitrary AC, when which obtains presence shape that AP is broadcasted, for obtaining the corresponding pre- roaming list items of the AP
After the request message of state, AC can go to check therein whether be stored with including the AP identification information pre- roaming list item,
To determine the existence of the corresponding pre- roaming list items of the AP.
S103, sends the response message for carrying first object data to the AP, so that the AP send configurations request report
The Wen Zhixiang AP send an AC in the AC of the response message for carrying first object data to be associated, wherein, first
Target data contains the pre- roaming list item for characterizing AC internal memories.
It is understood that can be provided with the configuration information for multiple AP in each AC in advance.
It should be noted that the quantity that the AC of the response message for carrying first object data is sent to the AP has two
Plant possible situation.
In the case of the first, the quantity that the AC of the response message for carrying first object data is sent to the AP is one.
In this case, the AP can directly to the AC send configuration request messages, after the AC receives the configuring request message, should
AC will issue configuration file corresponding with the AP to the AP.So, after the AP receives the configuration file that the AC is issued,
Which can be configured to itself according to the received configuration file, completed and Jing after the AC confirms in configuration operation, the AP
State will be converted to Run states, now the AP will set up its between the AC communication tunnel (access point control with supply
Answer CAPWAP tunnel, the tunnel can realize control message and data message interacting between AC and AP), finally, the AC and
The AP is able to successful association.
It should be noted that CAPWAP is a kind of agreement based on user datagram protocol UDP, the agreement is supported simultaneously
Ipv4 agreements and Ipv6 agreements.
In the case of second, the quantity that the AC of the response message for carrying first object data is sent to the AP is at least two
It is individual.In this case, AP can first be based on default selection rule, and an AC is selected from least two AC.Need
Bright, the basis for selecting of default selection rule exists various.Specifically, AP can be according to the time for receiving response message
Morning and evening chooses AC.For example, AP can will send response report that itself receives earliest, carrying first object data
The AC of text chooses out.It is emphasized that the basis for selecting of default selection rule is not limited to above-mentioned situation, specifically may be used
Determine with according to practical situation, this is no longer going to repeat them.After an AC is selected from least two AC, the AP can be to
The AC send configuration request messages out are chosen, the subsequent association flow process of the selection AC out and AP is with reference to the first feelings
The explanation of condition, will not be described here.Finally, the AC for choosing out also can be with the AP successful associations.
In this programme, after AP and AC set up and associate, if associating between AP and AC relieves, also, AP needs again
It is associated with AC, now, AP can be broadcasted for obtaining the corresponding pre- presence shapes for roaming list item of the AP at least one AC
The request message of state.Next, the AC for obtaining the request message can go to check that the therein AP that whether is stored with is corresponding pre-
Roaming list item, if be stored with, the AC will be generated and is stored with the corresponding pre- roaming list item of the AP for characterizing therein
First object data, and the response message for carrying first object data is sent to the AP.Afterwards, the AP can send configuration request
An AC in message to the AC sent to itself in the response message for carrying first object data is to be associated.Finally,
The AP can be with the AC successful associations for receiving configuring request message.
It can easily be seen that in this programme, when AP is associated with AC again, between the two operation associated has jumped
Now with the stage of addition, both are directly to proceed by association from configuration phase, therefore the time needed for AP is associated with AC again is big
The earth shortens, and occurs the situation that data service long-time is interrupted on the mobile terminal for so preferably avoiding AP services, and then
Preferable experience is brought to the holder of mobile terminal.
Referring to Fig. 2, a kind of another flow chart of correlating method that the embodiment of the present invention is provided in figure, is shown.Such as Fig. 2
Shown, the method may include steps of：
S201, obtains request message that AP is broadcasted, existence for obtaining the corresponding pre- roaming list items of the AP, its
In, the request message includes the identification information of the AP.
S202, according to the identification information of the AP, determines the pre- roaming list item that itself whether is stored with；If it is, performing
S203；If it has not, performing S204.
S203, sends the response message for carrying first object data to the AP, so that the AP send configurations request report
The Wen Zhixiang AP send an AC in the AC of the response message for carrying first object data to be associated, wherein, first
Target data contains the pre- roaming list item for characterizing AC internal memories.
Wherein, the specific implementation process of S201 to S203 will not be described here with reference to the explanation to S101 to S103.
S204, in the pre- roaming list item it is determined that itself is not stored with, sends to the AP and carries the second target data
Response message, so that the AP broadcast finds message, wherein, the second target data is used to characterize the pre- roaming that is not stored with AC
List item.
It is easily understood that for AP, broadcasting at least one AC at which corresponding pre- unrestrained for obtaining the AP
After the request message of the existence of trip list item, each response that a kind of possible situation, the i.e. AP are received now is there is
What is carried in message is the second target data.At this moment, AP cannot start to associate from configuration phase with a certain AC, in order to ensure AP
Successfully can be associated with a certain AC, now, AP can perform associated steps of the prior art, i.e., message is found from broadcast
Start, trial is associated with AC.
S205, in the discovery message for obtaining the AP broadcast, and after itself is associated with the AP, generates and stores the pre- roaming table
.
It is easily understood that when the AC performs associated steps of the prior art, and finally with the AP successful associations after, should
AC can be generated and be stored the corresponding pre- roaming list items of the AP.So, if the AC and the AP's associates due to originals such as Network Abnormals
Because relieving, after broadcast finds message, which can look for according to first object data whether are carried in response message the AP again
To the AC, and directly start to be associated with the AC from configuration phase, the AP need not perform complete association of the prior art
Step, therefore AP is associated again the required time and is greatly shortened with AC, so as to preferably avoid on the mobile terminal that AP is serviced
There is the situation that data service long-time is interrupted, and then the holder to mobile terminal brings preferable experience.
In a kind of specific embodiment of the embodiment of the present invention, the method can also include：
After itself is with the AP disassociations, trigger itself storage the pre- roaming list item it is aging, wherein, the pre- roaming
List item it is aging when a length of default duration threshold value.
Wherein, default duration threshold value can be 3 minutes, 10 minutes or 15 minutes, and this is all possible.Certainly, in advance
If the value of duration threshold value be not limited thereto, specifically can be determined according to practical situation, the present embodiment is not appointed to this
What limits.
It is understood that after AC is associated with AP, as long as the communication tunnel between AC and AP disconnects, AC and AP will
Disassociation.In general, whether the communication tunnel between AC and AP disconnects by keepalive mechanism determining.
For example, after AC and AP successful associations, for AP, which can be sent back to AC at set time intervals
Sound request message (Echo request), if AP is not received by AC replies in 3 seconds after echo request message is sent
Echo Reply message, AP can send the echo request message to AC again, if AP is secondary in continuous N (value of N can be 3)
Echoing and Echo Reply message is not received in 3 seconds after request message, it is logical between AC that AP will actively disconnect which
Letter tunnel.For AC, which can judge the interior echo request messages for whether receiving AP transmissions of 120S after successful association, such as
Fruit does not have, and AC will actively disconnect its communication tunnel between AP.
In the present embodiment, it is assumed that default duration threshold value is 3 minutes, so it is easy to understand that if AC and AP disassociations
Moment and AC receive request message moment between time interval be less than 3 minutes, then the AP and the AC just can be from
Configuration phase proceeds by association；If conversely, the time interval is not less than 3 minutes, then the AP and AC just cannot be from configuration
Stage is associated, and AP needs to perform existing, complete associated steps.
In a kind of specific embodiment of the embodiment of the present invention, the method can also include：
Generate and store this it is pre- roaming list item after, by this it is pre- roaming list item send to itself belong to same predetermined AC
Remaining AC of group, so that the received pre- roaming list item of remaining AC storage.
Wherein, the quantity of the AC in each predetermined AC groups can be two, three or more than three, and this is all possible
, the present embodiment does not do any restriction to the quantity of the AC in predetermined AC groups.
In the present embodiment, due to the AC can by the pre- roaming list item send to itself belong in same predetermined AC groups its
Remaining AC, therefore the pre- roaming list item that can all be stored with the every AC in the predetermined AC groups at AC places.So, even if the AC occurs
Failure, the AP also can be proceeded by from configuration phase with another AC in the predetermined AC groups and associated.It can easily be seen that the present embodiment
Ensure that the successful association of AP and AC.
In a kind of specific embodiment of the embodiment of the present invention, the method can also include：
After itself is with the AP disassociations, the AP is carried to sending with remaining AC for itself belonging to same predetermined AC groups
The association of identification information release notice message so that remaining AC is receiving after the association releases notice message, triggering from
Body storage this it is pre- roaming list item it is aging.
With reference to Fig. 3, the specific implementation process of the present embodiment is illustrated with a specific example.
As shown in Figure 3, it is assumed that AC1 and AC2 belong to same predetermined AC groups, AC1 and AC2 can set up communication between the two
Tunnel, to ensure the communication of AC1 and AC2.
Assume that AP is associated with AC1 first, after both AP and AC1 are successfully associated, in AC1, can generate and store the AP correspondences
Pre- roaming list item.Specifically, the mac address information and the AP of the AP can be included in the pre- roaming list item of AC1 memory storages
No. AP-ID.In addition, it is predetermined to include that HA-IP-Address, i.e. AC1 are located in the pre- roaming list item of AC1 memory storages
The IP address of the AC for being associated with the AP in AC groups at first, should be the IP address of AC1 herein.
While AC1 generates the pre- roaming list item, AC1 can send the pre- roaming list item to AC2.So, work as AC2
After receiving the pre- roaming list item, AC2 can store the pre- roaming list item, and finally, be stored with AC1 and AC2 the pre- roaming table
.
It is easily understood that after AC1 and AP disassociations, the corresponding pre- roaming list items of the AP of AC1 memory storages will
Start aging.Further, since the presence of the communication tunnel between AC1 and AC2, AC1 can send the mark that carry AP to AC2
The association of information releases notice message.So, after AC2 receives association releasing notice message, AC2 can also be triggered and itself be deposited
Storage this it is pre- roaming list item it is aging.
If before the ageing time of the pre- roaming list item in AC1 and AC2 reaches default duration threshold value, AC1 and AC2 is equal
The request message of the existence of the corresponding pre- roaming list items of acquisition AP of AP broadcast is have received, at this moment, AC1 and AC2 can
The response message for carrying first object data is replied to AP.AP after it have received the response message for coming from AC1 and AC2,
AP can be based on default selection rule, from AC1 and AC2 choose one.
It is easily understood that AP is based on default selection rule, existing two kinds when one is chosen from AC1 and AC2 can
The situation of energy.
In the case of one kind, that AP is finally selected is AC1, and now AP can be to AC1 send configuration request messages, so, AP
Can proceed by from configuration phase with AC1 and associate.
In the case of another kind, that AP is finally selected is AC2, now AP can to AC2 send configuration request messages, so,
AP can be proceeded by from configuration phase with AC2 and be associated.
If after the ageing time of the pre- roaming list item in AC1 and AC2 reaches default duration threshold value, AC1 and AC2 is equal
The request message of AP broadcast is have received, now, AC1 and AC2 can reply the response report for carrying the second target data to AP
Text.After AC receives the response message, AC can perform complete associated steps of the prior art, with AC1 and AC2 in
One is associated.
To sum up, in the present embodiment, the time needed for AP is associated with AC again greatly shortens, and so preferably avoids AP
Occur the situation that data service long-time is interrupted on the mobile terminal of service, and then the holder to mobile terminal brings preferably
Experience.
Below the present invention is illustrated from a kind of correlating method that the angle of AP is provided.
Referring to Fig. 4, the flow chart that a kind of correlating method that the embodiment of the present invention is provided is shown in figure.As shown in figure 4,
The method can include：
S401, at least one AC broadcast for obtain the AP it is corresponding it is pre- roaming list item existence request report
Text, wherein, request message includes the identification information of the AP.
It is understood that after each AC receives the request message, AC can go to check whether therein is stored with this
The corresponding pre- roaming list items of AP, and according to result is checked, it is determined that including the response message of corresponding contents.
S402, obtains the response message for the request message that at least one AC is replied；
S403, when carrying first object data at least one response message for obtaining, determines target AC, target AC
By an AC in the AC of first object data is carried in the response message replied, first object data should by what is replied
The AC that first object data are carried in answering message is given birth to when being determined according to the identification information of AP and itself being stored with pre- roaming list item
Into, and pre- roaming list item is contained for characterizing AC internal memories；
S404, send configuration request message to target AC is being associated.
In this programme, after AP and AC set up and associate, if associating between AP and AC relieves, also, AP needs again
It is associated with AC, now, AP can be broadcasted for obtaining the corresponding pre- presence shapes for roaming list item of the AP at least one AC
