## Abstract

Methods, apparatus and systems are described that manage a multi-level wireless node network with package ID nodes associated with different packages, a container node in a logistics container, a facility master node, and a server at different levels. In one method, the container node detects an advertising signal broadcast by each package ID node and detects an advertising signal broadcast by the facility master node as the container node approaches the facility. The method offloads management control of each of the package ID nodes from the facility master node down to the container node as part of managing the first level of the network, and has the container node transmitting relevant node information to the facility master node. Such relevant node information provides information about at least one of the packages in the logistics container and reflects status information to be sent to the server by the facility master node.

## Claims

### Claim 1

An enhanced logistics system for managing a multi-level wireless node network involving a plurality of packages, the system comprising:
a server disposed at a top level of the multi-level wireless node network, the server maintaining information on additional node elements of the multi-level wireless node network;
a facility master node disposed at a second level of the multi-level wireless node network, the facility master node being in operative communication with the server, the facility master node being associated with a facility that is capable of at least temporarily maintaining the plurality of packages;
a container node disposed at a third level of the multi-level wireless node network, the container node being part of a logistics container that currently maintains the plurality of packages, the container node further comprising a long range communication interface providing access to a long range communication path and a short range communication interface providing access to a short range communication path distinct from the long range communication path, wherein the container node is in operative communication with the facility master node over the long range communication path using the long range communication interface; and
a plurality of package ID nodes disposed at a fourth level of the multi-level wireless node network, wherein each of the plurality of package ID nodes are respectively associated with one of the plurality of packages currently maintained with the logistics container and in operative communication with the container node over the short range communication path via the short range communication interface; and
wherein as the container node enters the facility associated with the facility master node, the container node offloads management responsibility for each of the package ID nodes from the facility master node when
(a) the container node uses the short range communication interface to control each of the package ID nodes without direct communication between the package ID node and the facility master node, and
(b) the container node uses the long range communication interface to transmit relevant node information to the facility master node, the relevant node information comprising information about at least one of the packages and is gathered by the container node from at least one of the package ID nodes, and wherein the relevant node information reflects status information to be forwarded as an update by the facility master node to the server.

### Claim 2 (depends on 1)

The enhanced logistics system of claim 1, wherein the container node uses the short range communication interface to control each of the package ID nodes by being further operative to send each of the package ID nodes a control message through the short range communication interface, wherein the control message adjusts a broadcast setting for the respective package ID node.

### Claim 3 (depends on 2)

The enhanced logistics system of claim 2, wherein the control message is part of identifying a location of at least one of the package ID nodes in response to a location request received from the server by the facility master node and forwarded to the container node over the long range communication interface.

### Claim 4 (depends on 1)

The enhanced logistics system of claim 1, wherein the relevant node information provides information about the one of the package ID nodes and further comprises at least one of location data, profile data, security data, association data, shared data, and sensor data.

### Claim 5 (depends on 4)

The enhanced logistics system of claim 4, wherein the sensor data comprises data collected from a sensor on the one of the package ID nodes.

### Claim 6 (depends on 5)

The enhanced logistics system of claim 5, wherein the sensor data relates to at least one condition of the one of the packages.

### Claim 7 (depends on 4)

### Claim 8 (depends on 1)

The enhanced logistics system of claim 1, wherein the container node offloads management responsibility for each of the package ID nodes from the facility master node when a threshold level of node communication congestion exists within a part of the wireless node network normally managed directly by the facility master node.

### Claim 9 (depends on 1)

The enhanced logistics system of claim 1, wherein the container node conducts localized scanning via the short range communication interface proximate to the logistics container to detect an advertising signal broadcast by each of the package ID nodes; and wherein the container node transmits the relevant node information via the long range communication interface to the facility master node by formatting a message for transmission over the long range communication path, wherein the message providing the relevant node information to the facility master node as an update for the server.

### Claim 10 (depends on 9)

The enhanced logistics system of claim 9, wherein the container node conducts localized scanning via the short range communication interface proximate to the logistics container by using the short range communication interface to listen for the advertising signal broadcast from each of the package ID nodes located within the logistics container or located proximate to an exterior of the logistics container.

### Claim 11 (depends on 1)

The enhanced logistics system of claim 1, wherein the container node is responsible for scanning, via the short range communication interface, for each of the package ID nodes as part of managing the fourth level of the multi-level wireless node network while avoiding the overloading the facility master node with congested scanning responsibilities related to the plurality of package ID nodes and additional node devices in the wireless node network.

### Claim 12 (depends on 1)

The enhanced logistics system of claim 1, wherein the logistics container comprises a unit load device (ULD) container capable of being transported within an airplane.

### Claim 13 (depends on 1)

The enhanced logistics system of claim 1, wherein the logistics container comprises a trailer capable of being moved by a truck.

### Claim 14 (depends on 1)

The enhanced logistics system of claim 1, wherein the logistics container comprises a train car capable of being moved on a railway system.

### Claim 15 (depends on 1)

The enhanced logistics system of claim 1, wherein the logistics container comprises an intermodal shipping container capable of being moved on at least two different types of transportation modalities.

### Claim 16 (depends on 1)

The enhanced logistics system of claim 1, wherein the facility associated with the facility master node comprises a mobile facility that is capable of temporarily maintaining the logistics container.
