Description
Technical field
The present invention relates to field of locating technology, be specifically related to method, user side equipment and the control appliance of consumer positioning side apparatus.
Background technology
WLAN (wireless local area network) (WLAN, Wireless Local Area Network) technology is one of focus of the current communications field, compare with wired network, the startup of WLAN is relative simple with enforcement, maintenance cost is cheap, just can set up the LAN that covers whole building or area as long as generally lay one or more access point apparatus.
Fig. 1 is a networking exemplary plot of integral WLAN system, and as shown in Figure 1, it mainly comprises: wireless client (Client), WAP (wireless access point) (AP, Access Point) and Radio Access Controller (AC, Access Controller).Wherein, AP provides the bridging functionality of wireless client to local area network (LAN), carries out wireless wired and wired wireless frame conversion of arriving of arriving between wireless client and WLAN (wireless local area network); AC controls and manages all AP in the WLAN (wireless local area network).AP can be directly connected on the AC, also can be connected on the AC by two layers or three-layer network.
If operation IPv6 agreement between AC and the AP, then in the starting stage, AP uses neighbours to find that (ND, Neighbor Discovery) stateless disposes the IPv6 address that generates self automatically earlier, and detailed process is as follows:
When 01:AP reaches the standard grade, send router solicitation (RS, Router Solicitation) message to router.
02: router receives RS message, and (this message is carried network prefix for RA, RouterAdvertisement) message to return router advertisement to AP.
03:AP receives RA message, generates the IPv6 address of self according to the interface ID of the network prefix in the RA message and self generation.
Wherein, the generation method of interface ID is pre-configured on the AP by the keeper, specifically can be: generate according to interface mac address, perhaps generate according to random number, or the like.
AP utilization discovery mechanism is discerned AC.If AP uses the clean culture discovery mechanism, AP can ask dns server that the network address of AC is provided.AP uses the IPv6 address correlation that generates to AC then.In case wireless client is by authentication and be successfully associated with AP, WLAN that just can use authority serves and communicates with other wireless client and wireline equipment.
Wireless access point control and supply (CAPWAP, Controlling and Provisioning ofWireless Access Point) protocol definition how to communicate by letter between AP and the AC, provide a generic encapsulation and transmission mechanism for realizing the interoperability between AP and the AC.CAPWAP operates on AP and the AC simultaneously, for wlan system provides communicating by letter between safe AC and the AP.On AC, CAPWAP provides AP management function.AC can dynamically dispose AP according to the information that the keeper provides.
Operator, enterprise all might dispose the wireless aps network, and the scope of deployment may be greatly to a city, and is little of a building.In order to locate the particular geographic location of certain AP rapidly, at present, on AC, use the relevant information of CAPWAP configuration AP, wherein, the descriptor of configuration AP is the particular geographic location of AP, distinguishes certain number floor room, street etc. such as certain.
Fig. 2 has provided the flow chart of existing location AP, and as shown in Figure 2, its concrete steps are as follows:
Step 201:AP connects an AC for the first time, and AC finds that this AP does not report position (Location) character string, then according to the sequence number of AP, in the corresponding relation of the position character string of AP sequence number of self preserving and AP, finds the position character string of this AP.
Step 202:AC issues this position character string to AP, and AP receives and preserve this position character string.
Step 203: afterwards, AP is connected with other AC, and then AP initiatively reports current AC with the position character string of preserving.
Like this, any one AC in this AP connection can preserve the position character string of this AP, thereby the keeper can obtain the position character string of this AP from the AC in the AP connection, thus the geographical position of learning this AP.
Wherein, in the step 201, the corresponding relation of AP sequence number that AC preserves and the position character string of AP is by administrator configurations, particularly, check to keeper's meeting timing or not timing the associated AP situation on every AC, have an AP to be connected to for the first time on the AC if find, then this AP is positioned, then the sequence number of this AP and the corresponding relation of position character string are configured on this AC, then, AC is handed down to this AP with the position character string of this AP again.Obviously, this method is inconvenience very, and locating speed is very slow; In addition, because the keeper is at the AP that checks on the AC in the connection, like this, but only in the AP time spent, the keeper just can view this AP, thereby just can position this AP, and when AP is unavailable, then can't position this AP.Similarly, in other application scenario, also there is such problem, for example: in the time will positioning to the switch in the network, the keeper checks the connection switch situation on every NM server with also needing timing or not timing, if finding has a switch to be connected to for the first time on the NM server, then this switch is positioned, then the sequence number of this switch and the corresponding relation of positional information are configured on this NM server so that keeper's inquiry.Also do not provide at present the solution of this aspect.
