Embodiment 1

[0027] refer to figure 1 , Embodiment 1 of the present invention provides a mobile node positioning method, including:

[0028] 101. Determine the azimuth and radial distance of the mobile node relative to the anchor point;

[0029] Wherein, the azimuth angle of the mobile node relative to the anchor point is the deviation angle of the connection line between the mobile node and the anchor point relative to the communication beam of the smart antenna of the anchor point.

[0030] Wherein, this step may be to determine the azimuth and radial distance of the mobile node relative to the anchor point where the smart antenna is located according to the information of the smart antenna communication beam and the received signal strength information when the mobile node communicates with the smart antenna communication beam .

[0031] Specifically, this step can be implemented in the following two ways:

[0032] The first method: use the following two formulas to calculate the azi...

Embodiment 2

[0046] refer to figure 2 , Embodiment 2 of the present invention provides a mobile node positioning method, including:

[0047] 201. When deploying an anchor point (Anchor Point, AP), record the reference direction information of the smart antenna used by the anchor point and the position of the anchor point in the unified coordinate system.

[0048] Specifically, when deploying the anchor point, it is necessary to determine the reference direction of the reference beam of the smart antenna, the beam identifier and the beam width, and then the reference direction of any beam can be obtained according to the above information.

[0049] 202. The network entity used for positioning obtains the best communication beam information and adjacent communication beam information, obtains the RSSI information of the mobile node when the anchor point works on the best communication beam, and moves when the anchor point works on the adjacent communication beam The RSSI information of the n...

Embodiment 3

[0116] refer to Figure 6 Embodiment 3 of the present invention provides a mobile node positioning method, in which the network entity used for positioning is located on the mobile node, and the method specifically includes:

[0117] 601. When deploying an anchor point (Anchor Point, AP), the anchor point records the reference direction of the smart antenna used by the anchor point and the position of the anchor point in a unified coordinate system.

[0118] 602. The mobile node determines the optimal communication beam S according to the principle of maximum received signal strength 2 , to send a request to switch adjacent beams to the anchor.

[0119] 603. The anchor point switches to the adjacent communication beam, uses the adjacent communication beam to send information to the mobile node and sends the identification S of the adjacent communication beam to the mobile node 1 and S 3 .

[0120] 604. The mobile node records the identifier S of the adjacent communication ...

Abstract

The embodiment of the invention provides a mobile node positioning method and a mobile node positioning device. The mobile node positioning method comprises the following steps of: determining azimuth and radial distance of a mobile node relative to an anchor point; and determining the position of the mobile node according to the azimuth and radial distance of the mobile node relative to the anchor point, the intelligent antenna reference direction of the anchor point and the position information of the anchor point. By using the technical scheme provided by the embodiment of the invention, antenna cost and complexity can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile node positioning method and device. Background technique [0002] Traditional wireless network positioning methods are: based on Receive Signal Strength Indicator (RSSI), Time of Arrival (TOA), Time Difference of Arrival (TDOA), Angle of Arrival (AOA), among which RSSI is the easiest to implement and the most economical However, the signal strength information of multiple base stations is often required as a reference; the AOA / TOA hybrid positioning method only needs one base station to perform two-dimensional positioning of the mobile terminal, but its system is relatively complex and requires high equipment requirements; and The TDOA method also requires at least two base stations. [0003] With the popularization and application of smart antennas, the existing technology provides a solution for positioning mobile terminals using smart antennas with direction-f...
