specific implementation
Below in conjunction with the accompanying drawing in the embodiment of the present invention, clearly describe the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, are all the scope of protection of the invention.
The invention discloses a kind of address resource method for releasing and device, system, for saving address resource.Below be described in detail respectively.
Refer to Fig. 1, Fig. 1 is the flow chart of a kind of address resource method for releasing disclosed in the embodiment of the present invention.As shown in Figure 1, this address resource method for releasing can comprise the following steps.
S101, AP obtain the message that rolls off the production line for UE, and this message that rolls off the production line carries the hardware address of UE.
When UE initiatively rolls off the production line, the message that rolls off the production line of UE sends to AP by UE; When keeper allow UE roll off the production line, the situation such as the rate of UE are finished time, the message that rolls off the production line of UE sends to AP by controller.Wherein, the message that rolls off the production line of AP is sent to carry the hardware address of UE.In support, IEEE is (English: Institute of Electrical and Electronics Engineers, abbreviation: IEEE) WLAN (wireless local area network) (the English wireless local area network of 802.11, abbreviation: WLAN), the hardware address of UE is medium access control (English: media access control, abbreviation: MAC) address.
S102, when this AP is the certification AP of UE, AP sends DHCP and discharges message to Dynamic Host Configuration Protocol server, and to trigger the Dynamic Host Configuration Protocol server release IP address of UE and associating between UE, this DHCP discharges the hardware address that message comprises UE.
Alternatively, AP, after the message that rolls off the production line obtaining UE, will judge that the certification AP of this AP and UE is same AP.If this AP is the certification AP of UE, then show that UE certification is not roamed after reaching the standard grade, namely UE mono-is straight through AP accesses network, AP is by (English: DHCP RELEASE) message for the DHCP release generating UE, and DHCP is discharged message send to Dynamic Host Configuration Protocol server, discharge the message release IP address of UE and associating between UE to trigger Dynamic Host Configuration Protocol server according to the DHCP of UE.
Correspondingly, if this AP is not the certification AP of UE, then show that UE certification roams into AP from the certification AP of UE after reaching the standard grade, then AP sends DHCP release message and generates request to controller, indication information is sent to the certification AP of UE by controller, generate DHCP with the certification AP triggering UE and discharge message, and by the certification AP of UE, DHCP is discharged message and send to Dynamic Host Configuration Protocol server.This indication information comprises the hardware address of UE, and the certification AP of UE discharges at its DHCP sent the hardware address carrying UE in message according to the hardware address of the UE in this indication information.
In the address resource method for releasing described by Fig. 1, AP is after obtaining the message that rolls off the production line for UE, when AP is the certification AP of UE, sends DHCP and discharge message to Dynamic Host Configuration Protocol server, to trigger the Dynamic Host Configuration Protocol server release IP address of UE and associating between UE.In the embodiment of the present invention, after UE rolls off the production line, the IP address that release distributes to UE by Dynamic Host Configuration Protocol server, this IP address is become unappropriated IP address, and when there being new UE to apply for IP address, this IP address assignment is given new UE by Dynamic Host Configuration Protocol server, therefore, address resource can be saved.
Refer to Fig. 2, Fig. 2 is the flow chart of another kind of address resource method for releasing disclosed in the embodiment of the present invention.As shown in Figure 2, this address resource method for releasing can comprise the following steps.
S201, AP forward the IP address acquisition request of UE to Dynamic Host Configuration Protocol server, and to trigger Dynamic Host Configuration Protocol server to UE distributing IP address, this IP address acquisition request carries the hardware address of UE.
Alternatively, when AP receives the authentication request of UE transmission, then show that UE needs accesses network, therefore send the request of IP address acquisition to Dynamic Host Configuration Protocol server, to trigger Dynamic Host Configuration Protocol server to UE distributing IP address, and the IP address of distribution is sent to AP.Wherein, this IP address acquisition request carries the hardware address of UE, so that Dynamic Host Configuration Protocol server is to UE distributing IP address.
As a kind of possible execution mode, it is the IP address that UE distributes that AP obtains Dynamic Host Configuration Protocol server, generates the DHCP list item of UE.
AP is after the request of forwarding IP address acquisition is to Dynamic Host Configuration Protocol server, and receive the IP address assignment response that Dynamic Host Configuration Protocol server sends, this IP address assignment response comprises the IP address of UE.AP will generate the DHCP list item of UE afterwards, and the DHCP list item of UE comprises the mapping between the IP address of UE and hardware address.
S202, AP obtain the message that rolls off the production line for UE, and this message that rolls off the production line carries the hardware address of UE.
As a kind of possible execution mode, the message that rolls off the production line that AP obtains for UE can be the message that rolls off the production line of AP reception UE transmission, and this message that rolls off the production line carries the hardware address of UE; The message that rolls off the production line for UE that also can send for AP reception controller, this message that rolls off the production line carries the hardware address of UE and the reason that rolls off the production line of UE.
Alternatively, when UE initiatively rolls off the production line, the message that rolls off the production line of UE sends to AP by UE; When keeper allow UE roll off the production line, the situation such as the rate of UE are finished time, the message that rolls off the production line of UE sends to AP by controller.
Because AP discharges message in the process of Dynamic Host Configuration Protocol server at transmission DHCP, DHCP discharges message may through miscellaneous equipment.If these equipment employing DHCP monitors (English: DHCP snooping), whether the port that this DHCP of monitoring transmission is discharged message by DHCP snooping is consistent with the port in DHCPsnooping table, if inconsistent, then show that this message is illegal, abandon this message.Therefore, consistent with the path of the DHCP message in IP address assignment process in order to make DHCP discharge the forward-path of message, after AP receives the message that rolls off the production line of UE transmission, first need to judge that whether this AP is the certification AP of UE.
As a kind of possible execution mode, when AP receive that UE sends roll off the production line message time, AP judges that whether this AP is that the certification AP of UE can comprise the following steps.
The roaming information that A1, AP send for UE obtains request to controller, judges that whether AP is the certification AP of UE, and judged result is sent to AP with trigger controller.
Owing to rolling off the production line, message sends to AP by UE, if AP does not store the information whether AP is the certification AP of UE, the roaming information that AP sends for UE obtains request to controller, judges that whether AP is the certification AP of UE, and judged result is sent to AP with trigger controller.
A2, AP receive the judged result that controller sends.
AP send to obtain for the roaming information of UE request to controller after, receive the judged result that controller sends, and identify judged result whether to be AP be the certification AP of UE.
As a kind of possible execution mode, when AP receive that controller sends for UE roll off the production line message time, AP will judge that according to the reason that rolls off the production line of UE whether AP is the certification AP of UE.
Alternatively, when the message that rolls off the production line is that when sending to AP by controller, this message that rolls off the production line carries the reason that rolls off the production line of UE.The reason that rolls off the production line of UE comprises and directly to roll off the production line and roaming is rolled off the production line, directly roll off the production line be exactly UE from after certification to rolling off the production line one straight through AP accesses network, namely AP is the certification AP of UE; Roaming certification AP when being exactly UE certification that rolls off the production line carries out certification, and UE is not by certification AP accesses network but by AP accesses network before rolling off the production line, and namely UE roams into rolling off the production line after AP from certification AP.Therefore, can judge that whether AP is the certification AP of UE according to the reason that rolls off the production line of UE.
If controller that AP receives send for the reason that do not roll off the production line in the message that rolls off the production line of UE, then can adopt to receive with AP that UE sends roll off the production line message when identical mode judge that whether this AP is the certification AP of UE.
S203, when AP is the certification AP of UE, AP sends DHCP and discharges message to Dynamic Host Configuration Protocol server, and to trigger the Dynamic Host Configuration Protocol server release IP address of UE and associating between UE, this DHCP discharges the hardware address that message comprises UE.
If this AP is the certification AP of UE, then show that UE certification is not roamed after reaching the standard grade, namely UE mono-is straight through AP accesses network, AP is by (English: DHCP RELEASE) message for the DHCP release generating UE, and DHCP is discharged message send to Dynamic Host Configuration Protocol server, discharge the message release IP address of UE and associating between UE to trigger Dynamic Host Configuration Protocol server according to the DHCP of UE.
As a kind of possible execution mode, if AP is not the certification AP of UE, then AP sends DHCP release message and generates request to controller, indication information is sent to the certification AP of UE by controller, generate DHCP with the certification AP triggering UE and discharge message, and by the certification AP of UE, DHCP is discharged message and send to Dynamic Host Configuration Protocol server, this indication information comprises the hardware address of UE.
Alternatively, if AP is not the certification AP of UE, then show that UE certification roams into AP from the certification AP of UE after reaching the standard grade, need notice certification AP to generate DHCP release message in order to the DHCP release message generated is not dropped.Message generation request is discharged to the certification AP of UE because AP directly can not send DHCP, therefore, AP first sends DHCP and discharges message generation request to controller, discharge message by controller according to DHCP and generate request transmission indication information to the certification AP of UE, generate DHCP with the certification AP triggering UE and discharge message, and by the certification AP of UE, DHCP is discharged message and send to Dynamic Host Configuration Protocol server, to trigger the Dynamic Host Configuration Protocol server release IP address of UE and associating between UE.Wherein, indication information carries the hardware address of UE, and certification AP discharges at its DHCP sent the hardware address carrying UE in message according to the hardware address of the UE in this indication information.
Alternatively, when AP stores the DHCP list item of UE, it is generate according to the DHCP list item of UE that DHCP discharges message, and DHCP discharges hardware address and the IP address that message comprises UE.
Alternatively, ask after to controller when AP sends the generation of DHCP release message, AP will remove the DHCP list item of the UE stored.
In the address resource method for releasing described by Fig. 2, AP forwards the IP address acquisition request of UE to Dynamic Host Configuration Protocol server, to trigger Dynamic Host Configuration Protocol server to UE distributing IP address, obtain the message that rolls off the production line for UE, judge that whether AP is the certification AP of UE, when AP is the certification AP of UE, sends DHCP and discharge message to Dynamic Host Configuration Protocol server, to trigger the Dynamic Host Configuration Protocol server release IP address of UE and associating between UE.In the embodiment of the present invention, after UE rolls off the production line, the IP address that release distributes to UE by Dynamic Host Configuration Protocol server, this IP address is become unappropriated IP address, and when there being new UE to apply for IP address, this IP address assignment is given new UE by Dynamic Host Configuration Protocol server, therefore, address resource can be saved.
