Abstract

Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular mobile access point (AP). Such implementation includes determining such connection based on a relative proximity of an EN to the mobile AP, and a relative value of the connection between an EN and the mobile AP. Accordingly, a relative location of the EN may be determined based on such proximity, and particularly in response to mobility of the AP.

Claims

1. A BLE communications system, comprising:

a BLE access point (AP) configured to communicate with a network, in which a physical location of the AP is attributed to a BLE end node (EN) configured to initiate connection with the AP, in response to receipt by the EN of a beacon advertisement message received from the AP that identifies the AP as mobile with respect to positioning thereof,

wherein the location of the AP is attributed to the EN based on messaging of the AP to the network comprising (a) identifying information of the AP inserted into the messaging in response to the EN having initiated connection therewith and (b) positional information collected by the AP, which is indicative of the physical location thereof.

2. The BLE communications system of claim 1, wherein:

the AP is configured to comprise a backhaul enabling communication of the positional information of the AP to the network.

3. The BLE communications system of claim 2, wherein:

in order to collect the positional information, the AP is further configured to comprise any one of a GPS receiver, a WiFi receiver, and a cellular modem, each thereof enabling a determination of the location of the AP at the network.

4. The BLE communications system of claim 3, wherein:

each of the EN and the AP are configurable by the network.

5. The BLE communications system of claim 4, wherein:

the AP is configured to comprise a location of a target destination.

6. The BLE communications system of claim 5, wherein:

the EN is configured to transmit one or more heartbeat messages, through the AP and to the network, an interval between heartbeat messages corresponding to a proximity of the AP to the location of the target destination.

7. The BLE communications system of claim 6, wherein:

the interval decreases as the AP approaches the location of the target destination, whereby a number of the heartbeat messages transmitted to the network increases.

8. The BLE communications system of claim 7, wherein:

from among a plurality of mobile APs comprising respective positional information, the EN is configured to initiate a connection with a specified one of the plurality of mobile APs comprising a highest connection value, as determined by the EN.

9. The BLE communications system of claim 8, wherein:

the connection value is based on components comprising a confidence value representing a level of expectation that the specified one of the plurality of mobile APs is most proximate to the EN and a confidence value weighting factor, a network loading value for the network and a network loading value weighting factor, and an association factor for the specified one of the plurality of mobile APs.

10. The BLE communications system of claim 9, wherein:

the connection value is given by the equation,

σ

=α

·

P+β

·

L+γ

, in which

σ

represents the connection value, as an absolute value, α

represents the confidence value weighting factor, P represents the confidence value, β

represents the network loading value weighting factor, L represents the network loading value, and γ

represents the association factor for the specified one of the plurality of mobile APs, and is based on whether the specified one of the plurality of mobile APs has most recently connected with the EN.

11. The BLE communications system of claim 1, wherein:

the EN initiates the connection with the AP if the AP is determined by the EN to be most proximate the EN, from among a plurality of other mobile APs transmitting respective beacon advertisement messages received by the EN.

12. The BLE communications system of claim 11, wherein:

the AP is determined by the EN to be most proximate the EN as a result of an evaluation by the EN of a received signal strength (RSS) of the beacon advertisement message transmitted by the AP.
