Abstract

A method is disclosed of assessing timeslot interoperability between a first platform and a second platform communicating over a Time Division Multiple Access network. An exemplary method includes obtaining data representing a metamodel of communication characteristics of the first platform and the second platform, the metamodel including information regarding at least transmit timeslots for the first platform, and information regarding at least receive timeslots for the second platform. The method can be queried to assess interoperability between the transmit timeslots and the receive timeslots, for outputting timeslot interoperability data based on a result of the querying.

Claims

1. A method of assessing timeslot compatibility between a first platform and a second platform communicating over a Time Division Multiple Access network, the method comprising:

obtaining, by a processor onboard one of the first platform and the second platform, data representing a metamodel of communication characteristics of the first platform and the second platform, said first platform having a first base standard and said second platform having a second base standard different than the first base standard, wherein said first and second base standards define said communication characteristics of said first and second platform respectively, the metamodel including a first information regarding at least transmit timeslots for transmission by the first platform, and a second information regarding at least receive timeslots for reception by the second platform;

querying, by the processor, the metamodel to assess compatibility between the transmit timeslots and the receive timeslots, wherein a transmit timeslot is assessed to be compatible with a receive timeslot when the transmit timeslot coincides in time with the receive timeslot, and is assessed to be not compatible otherwise; and

outputting a timeslot compatibility map based on a result of the querying;

wherein obtaining data representing the metamodel comprises;

obtaining first and second network initiation source files for said first and second base standards respectively;

converting, when one or more of the source files is in a human-readable data catalogue format, said one or more source files in the human readable data catalogue format into a machine processable format; and

comparing each of the first and second source files with respective schematas, extracting respective relevant data from a first metamodel generated from the first source file and a second metamodel generated from the second source file and merging the respective relevant data into the metamodel.

2. A method according to claim 1, wherein said one or more source files include a human-readable Network Initialization Data Catalogue, and a machine-readable network initialization file.

3. A method according to claim 1, wherein the metamodel includes information regarding said receive timeslots corresponding to all timeslots transmitted in default net of the second platform.

4. A method according to claim 1, wherein the metamodel includes additional information relating to user-defined and/or domain-specific allocation of special case Network Participation Groups (NPGs) of which the first and the second platforms are members, the method comprising:

identifying additional, non-standard timeslot compatibility between the first and the second platforms using the additional information.

5. A method according to claim 1, wherein the metamodel includes information regarding said receive timeslots based on any special case Network Participation Groups (NPGs) of which the second platform is a member.

6. A method according to claim 5, wherein special case NPG receive timeslots include timeslot blocks transmitted by the first platform which the second platform can receive whenever it is not using these timeslot blocks to transmit.

7. A method according to claim 1, wherein the query includes queries selected from a set:

identifying the transmit timeslots of the first platform that the second platform is able to receive;

identifying the transmit timeslots of the first platform that the second platform is unable to receive, and/or identifying all the transmit timeslots of the first platform and all the receive timeslots, of the second platform.

8. A method according to claim 1, wherein the Time Division Multiple Access network includes a Tactical Data Link (TDL) network.

10. A computer program product comprising:

computer code stored in a non-transitory computer readable medium which, upon execution by a computer, causes the computer to execute the method of claim 1.

9. A system for assessing timeslot compatibility between a first platform and a second platform communicating over a Time Division Multiple Access network, the system comprising:

a processor, onboard one of the first platform and the second platform, configured to;

obtain data representing a metamodel of communication characteristics of the first platform and the second platform said first platform having a first base standard and said second platform having a second base standard, wherein said first and second base standards define said communication characteristics of said first and second platform and said communication characteristics are different may or may not be the same for said first and second platforms, the metamodel including a first information regarding at least transmit timeslots for transmission by the first platform, and a second information regarding at least receive timeslots for reception by the second platform;

query the metamodel to assess compatibility between the transmit timeslots and the receive timeslots, wherein a transmit timeslot is assessed to be compatible with a receive timeslot when the transmit timeslot coincide in time with the receive timeslot, and is assessed to be not compatible otherwise; and

outputting a timeslot compatibility map based on a result of the querying;

wherein obtaining data representing the metamodel comprises;

obtaining first and second network initiation source files for said first and second base standards respectively;

converting, when one or more of the source files is in a human-readable data catalogue format, said one or more source files in the human readable data catalogue format into a machine processable format; and

comparing each of the first and second source files with respective schematas, extracting respective relevant data from a first metamodel generated from the first source file and a second metamodel generated from the second source file and merging the respective relevant data into the metamodel.
