Description

Grid point configuration distributing method and grid point in the WLAN (wireless local area network) grid network
Technical field
The present invention relates to the radio configuration technical field, relate in particular to grid point (MP, Mesh Point) configuration distributing method and MP in WLAN (wireless local area network) (WLAN, the Wireless Local Area Network) grid network.
Background technology
A large amount of when disposing access points (AP, Access Point) in WLAN, to the AP upgrade software, the management work such as transmitting power is set will brings very high running cost to the user.For addressing this problem, WLAN new trend occurred at application developments such as enterprises: thin (Fit) AP framework.Namely by wireless controller (AC, Access Controller) manages a plurality of AP, adopt certain tunnel protocol between AP and AC, as: wireless access point control and supply (CAPWAP, Controlling and Provisioning of Wireless Access Point) agreement is carried out communication, and the processing of wireless access message is shared realization between AP and AC.
The CAPWAP agreement provides general encapsulation and transmission mechanism for the communication between AP and the AC.CAPWAP user datagram protocol (UDP, User Datagram Protocol) is as host-host protocol, and support IPv4 and IPv6 agreement.
The pre-configured function of AP provide a kind of on AC the basic network parameter to Fit AP be configured, and configuration information is issued to the method for Fit AP.The configuration meeting that is issued to Fit AP saves as privately owned configuration file at AP, and when the Fit ap reboot, privately owned configuration file comes into force.It should be noted that AC can only send to configuration information sets up CAPWAP/ Lightweight Access Point Protocol (LWAPP, Light Weight Access Point Protocol) tunnel with it and connects, i.e. the current Fit AP that is in operation (Run) state.The pre-configured preservable information of AP comprises IP address, the domain name system (DNS of AC, Domain Name System), the network of relation setting such as interface, all right configuration of IP safety (IPsec) key information, can under encrypted state, carry out when making the pre-configured AP of acquisition and AC carry out message interaction, improve communications security.
Fig. 1 is in the existing wlan network, and Fit AP discovery also is associated with AC and obtains the message flow chart of configuration from AC, and as shown in Figure 1, detailed process is as follows:
After step 101:Fit AP started, request (Discovery Request) message was found in broadcasting.
After step 102:AC receives this Discovery Request message, send discovery response (Discovery Response) message to AP.
After step 103:AP receives Discovery Response message, the state of the LWAPP state machine of self maintained is changed into clean culture be found to adding (Unicast Discovery to Join), send (Join Request) message that joins request to the AC clean culture.
Step 104:AC receives this Join Request message, and the state of the LWAPP state machine of this AP of self maintained is become addings (Join) by idle (Idle), and sends to add to AP and respond (Join Response) message.
After step 105:AP receives Join Response message, send adding to AC and receive notice (Join Ack) message.
After step 106:AC receives Join ACK message, the LWAPP state machine of this AP is become JoinAck by Join, send to add to AP and confirm (Join confirm) message.
After step 107:AP receives Join Confirm message, send configuration state request (Configuration Status Request) message to AC, this message carries some basic parameters of AP, such as RF capabilities collection, radio frequency media access control (MAC, Media Access Control) address etc.
After step 108:AC receives Configuration Status Request message, send configuration state response (Configuration Status Response) message to AP, this message carries the basic configuration information of this AP.
The configuration information of AP is divided into basic configuration information and other configuration informations, in this step, issues basic configuration information by Configuration Status Response message first.
After step 109:AP receives Configuration Status Response message, be configured according to the basic configuration information in the message, the LWAPP state machine is become the Run state, and to AC transmission change state event request (Change State Event Request) message, AC changes running status with notice.
Step 110:AC receives Change State Event Request message, and the state of the LWAPP state machine of this AP of change self maintained is Run, and returns change state event response (Change State Event Response) message to AP.At this moment, the CAPWAP tunnel between AP and AC is set up.
Step 111: when AP was in the Run state, AC can issue other configuration informations to AP by config update request (Configuration Update Request) message, and AP receives and responds.Do not have the type lengths values (TLV that carries in the mandatory provision Configuration Update Request message among the CAPWAP, Type Length Value), after AP reaches the standard grade generally speaking, AC can send many Configuration Update Request messages to AP, because upper each business module of AC can send own relevant configuration to AP by this message.If the configuration on the follow-up AC is made amendment, also can upgrade the configuration of AP by this message.
Step 112: if used the pre-configured function that issues on the AC, pre-configuredly also can be handed down to AP by Configuration Update Request message, AP receives rear answer response, and pre-configured file is saved in local flash memory (Flash).
WLAN grid (Mesh) network is a kind of WLAN of newtype.Different from traditional WLAN is to be wireless connections between the AP in the WLAN Mesh network.Fig. 2 is existing typical Mesh networking schematic diagram, in WLAN Mesh network, the AP that starts the Mesh function is referred to as MP, wherein with the wired direct-connected grid authentication point (MPP that is called of AC, Mesh Portal Point), the MP of client access is called grid access point (MAP, Mesh Access Point).
If AP accesses AC by the Mesh mode, and be not MPP, then AP can carry out first the Mesh connection negotiation before setting up process carrying out CAPWAP tunnel, and follow-up CAPWAP process connects the basis at Mesh and carries out.Fig. 3 has provided in the existing WLAN Mesh network, and the AP discovery also is associated with AC and obtains the message flow chart of configuration from AC, and as shown in Figure 3, detailed process is as follows:
After step 301:AP starts, according to the role who whether has wired connection decision-making oneself.If there is effective wired connection, then think it oneself is MPP, directly find by wired connection and be associated with AC, obtain and finish the configuration of Mesh characteristic; If there is no wired connection then thinks it oneself is common MP.
Step 302: the MP of non-MPP, namely common MP scans neighbours MP, and the neighbours MP that selects successfully to be associated with AC sets up Mesh with it and is connected as reciprocity point (Peer).It is unsafe connection that the Mesh that sets up this moment connects.
Step 303: this common MP connects by the Mesh that sets up and DHCP (DHCP, Dynamic Host Configuration Protocol) server interaction gets access to the IP address, finishes network configuration.
Dynamic Host Configuration Protocol server and AC are in the same network segment.
Step 304: this common MP begins the discovery AC process of CAPWAP and finishes related with AC, downloads the configuration of self from AC.
Common MP finds and is associated with the process of AC, need to be undertaken by MPP.
Step 305: this common MP removes the previous Mesh that sets up and connects, and the Mesh that rebuilds safety connects.In this process, this common MP again carries out first equity and connects open (Peer Link Open)/affirmation (Confirm) message interaction, and then carry out Extensible Authentication Protocol (EAP, Extensible Authentication Protocol) authentication (optional) and 4 road is shaken hands, and negotiates the final key that signal post needs between Peer.
The shortcoming of prior art is as follows:
If AP wants to obtain specified configuration, must set up a CAPWAP with AC first and connect, again from the AC download configuration.In other words, AC can only send to configuration information and set up the tunnel with it and be connected, and namely the current Fit AP that is in the Run state so before AC configuration AP configuration information, need to guarantee that AP is in the Run state, can't skip CAPWAP tunnel and set up process.
