DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the disclosure. As used herein, the word “exemplary” means “serving as an example, instance, or illustration.” Thus, any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. All of the embodiments described herein are exemplary embodiments provided to enable persons skilled in the art to make or use the invention and not to limit the scope of the invention which is defined by the claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary, or the following detailed description.

Referring now to FIG. 1, exemplary embodiments of the present disclosure are directed to a communication management system shown generally at 10. In various embodiments, the communication management system 10 manages communications between a vehicle 12 and a fixed element, such as a ground element 14. As can be appreciated, in various other embodiments, the communication management system 10 described herein can be associated with any vehicle 12 that communicates with any fixed element or any other non-fixed element such as another vehicle (not shown). For example, the vehicle 12 or other vehicle (not shown) can be any aircraft, ground vehicle, or sea craft. In another example, the ground element 14 can be any aircraft, ground vehicle, or sea craft related ground element. For exemplary purposes, the disclosure will be discussed in the context of the vehicle 12 being an aircraft 12 that communicates with a ground element 14 that is an aircraft related ground system.

In the example of FIG. 1, the vehicle 12 is an aircraft having a computing device 16 that communicates with the ground element 14. The computing device 16 may be located in a cockpit of the aircraft 12 for interaction by, for example, a pilot or maintenance personnel of the aircraft 12. The computing device 16 may alternatively be located in another area of the aircraft 12 and may be operated by other occupants or individuals associated with the aircraft 12. The ground element 14 is a ground system (such as a maintenance system, or an air traffic control system, or any other aircraft related system) that includes a computing device 18 that communicates with the computing device 16 of the aircraft 12.

Each of the computing devices 16, 18 generally includes one or more processors 20, 22, and one or more data storage devices 24, 26 that communicate with one or more input/output devices 28, 30 and one or more communication devices 32, 34. The communication devices 32, 34 are configured to directly or indirectly communicate with each other using one or more communication methods. For example, the communication devices 32, 34 may communicate directly using a predefined communication protocol (e.g., UHF, VHF, FM, Ethernet, RS-232, RS-422, Mil-STD-1553/1773, etc.) and/or may communicate indirectly through one or more communication networks 36 that communicate via one or more predefined communication protocols (e.g., cellular communication networks, Wi-Fi, etc). The direct communication and the indirect communication will hereinafter be commonly referred to as communication mediums.

In accordance with the present disclosure, the computing device 16 of the aircraft 12 includes a communication manager module 38. The communication manager module 38 is stored in the data storage device 24 and includes instructions that can be executed by the processor 20. The instructions, when executed, cause the communication manager module 38 to manage a communication path for data being transmitted from the computing device 16 to the ground element 14. In various embodiments, the instructions, when executed, cause the communication manager module 38 to configure parameters for managing the communication paths. The parameters may be based on an attributes associated with the various communication methods. The configuration of the parameters can be performed, for example, based on a user interacting with the computing device 16 (e.g., via an interface and the input/output device 28) to create the configuration parameters, or based on a configuration file that stores parameters and that is provided to the computing device 16.

In various embodiments, the instructions, when executed, further cause the communication manager module 38 to modify a current path of communication during transmission of the data based on the parameters and attributes associated with available communication mediums. For example, the communication manager module 38 can identify a current path based on the parameters and attributes of available communication means and can modify the current path during transmission of the data when a communication medium with a desired attribute becomes available.

Referring now to FIG. 2, a dataflow diagram illustrates various embodiments of the communication manager module 38. Various embodiments of communication manager modules 38 according to the present disclosure may include any number of sub-modules embedded within the communication manager module 38. As can be appreciated, the sub-modules shown in FIG. 2 may be combined and/or further partitioned to similarly manage the communication paths between the aircraft 12 (FIG. 1) and the ground elements 14 (FIG. 1). Inputs to the communication manager module 38 may be received from other modules (not shown) of the aircraft 12 (FIG. 1) or computing device 16 (FIG. 1), determined/modeled by other sub-modules (not shown) within the communication manager module 38, and/or may be some other form of user input that is based on a user interacting with the computing device 16 (FIG. 1). In various embodiments, the communication manager module 38 includes a parameter configuration module 40, a priority scheme determination module 42, an available medium determination module 44, a path determination module 46, and a communication module 48.

The parameter configuration module 40 receives as input configuration data 50. The parameter configuration module 40 determines configuration parameters 52 based on the configuration data 50. In various embodiments, the configuration data 50 may be part of a pre-stored configuration file that is configured and stored by a user. In various other embodiments, the configuration data 50 is received based on a user's interaction with a configuration user interface. In such embodiments, the parameter configuration module 40 may generate user interface data 54 that is used to display the configuration user interface for generating the configuration data 50.

The configuration parameters 52 include attributes associated with communication mediums. For example, the attributes can include, but are not limited to speed of transmission, cost to user, reliability of the transmission, or any other factors. The configuration parameters 52 further include one or more rankings of the attributes. The rankings can indicate a priority of the attributes as they pertain to the communication of data. For example, a ranking may prioritize speed of a transmission over reliability of the transmission.

In various embodiments, the configuration parameters may further include conditions. The conditions may be associated with the particular attributes and/or the particular rankings. The conditions can be based on criteria other than the communication mediums such as, but not limited to, criticality of the data to be transmitted, a location of the vehicle, security requirements for the data to be transmitted, etc. By associating conditions with the attributes and/or rankings, multiple rankings for multiple attributes may be provided.

The priority scheme determination module 42 receives as input the configuration parameters 52. The priority scheme determination module 42 determines a priority scheme 56 based on the configuration parameters 52. For example, the priority scheme determination module 42 sets conditions of the priority scheme based on the condition parameters; and the priority scheme determination module 42 associates the rankings of the attributes with the particular conditions.

The available medium determination module 44 receives as input communication medium data 58. The communication medium data 58 includes data that indicates the availability of various communication mediums. The available medium determination module 44 determines available communication mediums 60 based on the communication medium data 58. For example, the available medium determination module 44 evaluates a location or an operating state of the aircraft 12 (FIG. 1) and the communication medium data 58 to determine the available communication mediums 60.

The path determination module 46 receives as input the priority scheme 56, the available mediums 60, and data to be transmitted 62 (or data about the data to be transmitted). The path determination module 46 determines a communication path 64 through one or more of the available communication mediums 60 based on the priority scheme 56. For example, when the priority scheme 56 indicates that the cost attribute is given the highest priority for all standard data, the available communication medium with an associated lowest cost attribute is selected for the path 64. If, however, the data to be transmitted 62 is considered high-criticality data, and the priority scheme 56 indicates that the reliability attribute is given the highest priority for high-criticality data, then the available communication medium with an associated most reliable attribute is selected for the path 64.

The communication module 48 receives as input the communication path 64 and the data to be transmitted 62. The communication module 48 transmits the data 66 or prepares the data for transmission based on the communication path 64. For example, if the communication path 64 indicates a first communication medium, then the communication module 48 transmits the data 66 using a connection and the communication protocol of the first communication medium. If however, during the transmission, the communication path 64 has been updated to another communication medium, then the communication module 48 pauses the transmission on the first communication medium, and resumes the transmission using a connection and a communication protocol of the other communication medium.

Referring now to FIG. 3, and with continued reference to FIGS. 1 and 2, a flowchart illustrates a communication method that can be performed by the communication manager module 38 of FIG. 2 in accordance with the present disclosure. As can be appreciated in light of the disclosure, the order of operation within the method is not limited to the sequential execution as illustrated in FIG. 3, but may be performed in one or more varying orders as applicable and in accordance with the present disclosure. As can further be appreciated, one or more steps may be added or removed from the method shown in FIG. 3, without altering the spirit of the method.

In various embodiments, the method can be scheduled to run based on predetermined events, and/or can run continually during operation of the aircraft 12.

The method may begin at 100. At 110, it is determined whether new configuration parameters 52 are received (e.g., based on a user interacting with a user interface, based on a configuration file, or based on some other method). If new configuration parameters 52 are not received at 110, the method continues with determining whether data is to be transmitted at 130.

If, however, new configuration parameters 52 are received at 110, the communication priority scheme 56 is determined based on the configuration parameters 52 and is stored for future use at 120. For example, as discussed above, the configuration parameters 52 indicate what attributes of the communication mediums are to be evaluated and indicate a ranking associated with the attributes. In various embodiments, the configuration parameters additionally include conditions that are to be evaluated in addition to or alternative to the ranking.

The method continues at 130 with determining whether data is to be transmitted. If data is not to be transmitted at 130, the method may end at 140. If, however, data is to be transmitted at 130, the available communication mediums 60 are determined at 150 (e.g., based on a current location or other available information). The communication path 64 is then determined based on the priority scheme 56 (either the newly updated priority scheme or a previously stored priority scheme) and the available communication mediums 60. For example, the attributes of the available communication mediums 60 are evaluated and the communication medium with the highest ranked attribute is chosen for the communication medium unless a condition is met which indicates another communication medium should be used.

The data is communicated using the selected communication path 64 at 170. It is evaluated whether the communication of the data is complete at 180. If the communication of the data is not complete at 180, conditions are checked to see if a new communication path can be determined at 190. If conditions have not changed, then the data is communicated at 170 until the communication is complete at 180. Thereafter the method may end at 140.

If, however, conditions have changed, then the available communication mediums 60 are determined at 150, the communication path 64 is determined at 160, and the data is communicated at 170. During transmission at 170, if the communication path 64 has changed, the transmission of the data on the first path is temporarily paused (if it has not already stopped), and the transmission of the data is resumed on the new path. The transmission occurs until it is complete at 180 and the method ends at 140.
