Description
Technical field
The present invention relates to a kind of wireless local area network technology, the dynamic assignment and the recovery method of interim MAC Address in particular a kind of WLAN (wireless local area network).
Background technology
WLAN of the prior art (WLAN (wireless local area network)) technology because of its in the wireless penetration characteristics, can compare two-forty wired and insert and advantage such as cheap is subjected to the welcome in market deeply, wired occasions such as family, campus, hotel, enterprise's office that are widely used in have been begun to replace at present, and begin to be widely deployed in public's focus place as a kind of WiMAX access technology, the access service of public wireless broadband data is provided.
ISO/IEC 8802-11:1999 " telecommunication and information exchange local net and metropolitan area network particular requirement the 11st part between information technology system: WLAN media interviews control (MAC; Media AccessControl address is the sign of identification LAN node) and physical layer (PHY) standard " is the international standard of WLAN, the corresponding IEEE 802.11 of its content.
China has also issued WLAN standard GB/T 15629.11-2003, and the main difference of itself and international standard is on the security mechanism of access control difference is arranged.In fact, the wlan product of market extensive use mainly is the additional standard at IEEE 802.11 of IEEE 802.11 standards project groups issue, comprises IEEE 802.11b, IEEE 802.11g, IEEE 802.11a etc.Wherein, 802.11b, 802.11g work in the 2.4Hz frequency range, and 802.11a is operated in the 5GHz frequency range.802.11b the physical layer rate of supporting can reach 11Mb/s, the physical layer rate that 802.11g, 802.11a support can reach 54Mb/s.At present IEEE 802.11 working out support high-throughput more standard 802.11n to support various real time business and multimedia application better, increase power system capacity.
The wlan system of existing IEEE 802.11 definition, its basic structure as shown in Figure 1, STA (Station) refers to comprise the terminal equipment of IEEE 802.11 wireless lan interfaces, and many in the market mobile phones are all supported wireless lan interfaces, the also built-in wireless lan interfaces of portable machine.Not with the equipment of wireless lan interfaces, can provide wireless lan interfaces for some by the mode of WLAN wireless network card is installed.
As shown in Figure 1, AP (Access Point) is an access point, the base station that is equivalent to the mobile network, its major function is to make STA to communicate with other the STA or the relevant device of cable network, for example: a plurality of STA are linked into WLAN (wireless local area network) of an AP composition and communicate, the STA that is linked into different AP forms a local area network (LAN) and communicates, and the relevant device of STA and cable LAN communicates.Be associated with this services set of STA primordial (BSS) under the AP.
Wherein, DS (Distribution System) is that dissemination system makes between the different BSS and can form a big local area network (LAN) between BSS and the cable LAN.Wherein portal is meant provides the logical point that MAC service data unit (MSDUs) is transmitted between DS and the cable LAN.
In existing wlan system, SSID (Service Set Identifier) is used to distinguish different WLAN (wireless local area network).When different BSS (identifying with BSSID) formed a big local area network (LAN) by DS, they had same SSID.
802.11 operation principle of prior art as shown in Figure 2, among the figure example flow process of drive sweep, AP periodically sends broadcast frame (Beacon frame or claim beacon frame), i.e. beacon process on its working channel.When STA is in the drive sweep mode, broadcast listening frame at first, and according to the AP of its management information of carrying to select the candidate to insert.STA also can adopt a kind of mode of active scan to replace drive sweep, be that STA sends Probe Request (request of inquiring after) on respective channels, the AP that works in this channel returns Probe Response (inquiring after response), carry be equal to Beacon or more information.
By scanning, STA can obtain the information of related system, comprises physical layer and media access control layer (MAC) layer relevant parameter and ability support etc., as security parameter RSN IE (Robust SecurityNetwork Information Element).
When STA determines to join corresponding BSS, can carry out one 802.11 authentication process between STA and the AP.Support two class authentications at present: share key authentication (Shared Key Authentication) and open system authentication (Open System authentication).Share between key authentication supposition STA and the AP and have common key, cryptographic algorithm employing WEP (Wireless Equivalent Privacy).The open system authentication does not then comprise any cryptographic algorithm, and it is open being equivalent to system.802.11i be that it has directly adopted the port controlling mechanism of 802.1X at 802.11 enhancings in fail safe, for 802.11, STA is to the port of the corresponding 802.1X of association of AP.In 802.11 authorization phase, 802.11i uses the open system authentication.On principle, the WAPI safety standard of China also is similar to 802.11i, and just the method for authenticating that requires is different with cryptographic algorithm.
After finishing 802.11 authentication processes, just begin to set up the association of STA to AP.At first, STA sends related request, comprises associated safety parameter such as RSN IE in the related request.AP responds associated response, and is related ID of this associated allocation (Association ID).For RSN, related 802.1X control port of being answered surely will be closed, and just open with installation up to finishing the 802.1X key agreement.
Access authentication procedure after related is exactly the 802.1X/EAP access authentication procedure concerning RSN.The UAM (Universal Access Method) that Wi-Fi Alliance recommends is based on the another kind of access authentication mode of Browser Hijack, be that system forces STA to be connected to a page is inputed user name and encrypted message as the user window, the AS of this page and rear end carries out information interaction, but UAM does not support 802.11i at present.
The terminal equipment of prior art is to the demand situation of interim MAC Address, for example when the identify label that has a plurality of service providers on the STA (if any mobile phone can support a plurality of SIM card) time, can obtain voice service and obtain data, services from a service provider from another service provider.If the stand-alone terminal that STA can external a plurality of other types also can obtain the WLAN access service by sharing this STA.Need to provide a kind of virtual STA realization mechanism so, can initiate independently access authentication flow process and can distinguish separately independently Business Stream of a plurality of identity on the physics STA to be supported in, virtual STA model as shown in Figure 3, a STA can create according to service needed and fictionalize one or more virtual STA, V-STA1 as shown in Figure 3 and V-STA2 can support one the tunnel or multichannel Business Stream independently like this.Each virtual STA on each physics STA distinguishes a corresponding independently interim MAC Address (T-MAC-ADDR is called for short TMA to adopt in the description of lower part), has independently authentication, relevant parameter and independently safety, QOS service.Virtual STA sets up flow process as shown in Figure 4, has been application protection in applicant's the separate case patent application.
In WLAN (wireless local area network), still do not have the mechanism of distributing and reclaiming interim MAC Address (T-MAC-ADDR) in the prior art, so the STA of hardware just can't support independently one or more business, thereby can't create virtual STA.Therefore, prior art awaits continuing development.

Embodiment
Below in conjunction with accompanying drawing, will carry out comparatively detailed explanation to each preferred embodiment of the present invention.
The system configuration of the inventive method is provided with an interim MAC Address manager as shown in Figure 5 on the dissemination system DS in existing wireless local area network (WLAN) system, be used for the distribution of an interim MAC Address of WLAN terminal of unified management.Be a standalone feature entity on the interim MAC Address manager logic, help DS to realize interim MAC Address management function with respect to the AP functional entity.
Its data transfer is; the packet that derives from STA sends to DS or derives from DS sends to STA through AP packet through AP; in DS, use the STA true address; the STA temporary address only is used to replace real MAC address between AP and STA; use as the shielded STA of sign on eating dishes without rice or wine; its sphere of action only in wlan network, is used in wlan network, can not be delivered to external network and client.
Interim MAC Address (T-MAC-ADDR) distribution in the inventive method and reclaim mechanism and interim MAC Address state conversion process are as follows:
The assigning process of described interim MAC Address has been represented the allocation flow of interim MAC Address (T-MAC-ADDR) as shown in Figure 6 and Figure 7.
STA sends temporary address request for allocation (TMA-ALLOCATE.request) to AP, has wherein carried and has required to distribute the corresponding virtual STA instance number of temporary address, and started overtime retransmission timer TR.Like this, still can not receive temporary address assignment response (TMA-ALLOCATE.response) if send TMA-ALLOCATE.request for three times, this virtual STA is with deleted.Because a virtual STA needs an interim MAC Address, so a physics STA just might apply for a plurality of different interim MAC Address.
After AP receives the temporary address request for allocation of STA, real MAC address and the corresponding virtual STA instance number of STA are noted, then the temporary address request for allocation is packaged into " interim MAC Address generates request " two layers of frame and passes to described interim MAC Address manager, wherein carry real MAC address and the corresponding virtual STA instance number of STA.
Described interim MAC Address manager distributes an interim MAC Address, and it is changed to " using " state.Then should interim MAC Address and life span be encapsulated in interim MAC Address and generate response and pass to AP, and start life span timing to this interim MAC Address.
AP is encapsulated in the result " interim MAC Address assignment response " and returns to STA in (TMA-ALLOCATE.response).After STA creates virtual STA like this,, can use this interim MAC Address to replace the real mac address of STA according to the needs of business, and interactive information aloft between the AP.
The information that described virtual STA basis is received also starts the timer of a life span timing, is used for noting down synchronously with described interim MAC Address manager the life span of this interim MAC Address.
If described interim MAC Address manager can't distribute interim MAC Address in said process, the parameter of distributing failure can carried in the message response that return.The STA application is less than interim MAC Address, and the virtual STA of corresponding virtual STA instance number creates failure, and flow process finishes.
Removal process to interim MAC Address in the inventive method comprises:
The reclaim mechanism of interim MAC Address of the present invention can make that the interim MAC Address manager on the DS can be safeguarded the interim MAC Address that dispenses.Reclaim mechanism described herein comprises the recovery to this interim MAC Address of the release of interim MAC Address of virtual STA side and network side.
At first as shown in Figure 8, newly-increased idle Idle state on existing 802.11 state machine bases, represent that virtual STA does not create as yet and TMA is still unallocated, simultaneously original State 1, State 2, State3 are referred to as virtual terminal equipment and enliven VSTA Active state, as shown in Figure 9, represent that virtual STA has created and TMA distributes.Like this, state machine uses the two-stage flow chart to describe, and wherein, level0 is Idle and VSTA Active state, and level 1 is the segmentation to VSTA Active state, comprises State 1, State 2, State 3.
When 802.11 state machines of virtual STA when VSTA Active returns to the Idle state, may be to become the Idle state from State3, also may be directly to return the Idle state from State 1, represent that this virtual STA has not needed this interim MAC Address, discharge the release that request identifies the temporary address by interim MAC Address between its access point and this virtual terminal equipment, and should interim MAC Address reclaim by the interim MAC Address manager of network side.
Described recovery and dispose procedure to interim MAC Address, as shown in figure 10, when initiating request by the STA side, STA sends interim MAC Address and discharges request to AP, AP is transmitted to described interim MAC Address manager and handles, and feed back interim MAC Address to described STA and discharge response, this physics STA deletion corresponding virtual STA; When initiating to discharge request by network side, as shown in figure 11, send interim MAC Address by AP to described STA and discharge request, send to described interim MAC Address manager simultaneously and handle, described STA feeds back interim MAC Address to AP and discharges response, and deletion corresponding virtual STA.
In addition, when interim MAC Address is upgraded in the STA request, initiatively initiate interim MAC Address by virtual STA and change, interim MAC Address address manager upgrades a new interim MAC Address for virtual STA, and with former interim MAC Address recovery, its removal process and the inventive method are similar, repeat no more.Described renewal process is asked for an interview the applicant's the patent application same period " the interim MAC Address of terminal dynamically updates method in a kind of wireless local area network (WLAN) system ".
Interim MAC Address state conversion process in the described interim MAC Address manager of the inventive method as shown in figure 12, respond interim MAC Address and divide timing, if the interim MAC Address of " waiting to be allocated " state is arranged in the interim MAC Address manager, then this interim MAC Address is changed to " distribute, use " state, distributes to virtual STA; If no, unique interim MAC Address in the then newly-generated DS scope is changed to " distribute, use " state, and corresponding virtual STA is given in reallocation.
Exist this situation: STA and AP before changing interim MAC Address, a delay to be arranged, and described interim MAC Address manager may be distributed to this interim MAC Address other virtual STA uses at once, can cause same interim MAC Address by the situation that two virtual STA use thus, cause these two virtual STA communication failure to occur.In order to evade similar abnormal conditions, the inventive method has been done following regulation: the interim MAC Address that is recovered can not be dispensed at once, must be changed to " initialization " state, one period scheduled time, after one minute, just be changed to " wait " state, just have an opportunity by sub-distribution more then.
