Abstract

A method and apparatus for management of communications of a moving platform comprising a plurality of platform applications, a communications system configured to transmit data received from the at least one platform application and to effect wireless data communication by means of one of a plurality of supported communication links, and a data management module, the apparatus and method being configured to:
receive performance data indicative of a current available bandwidth of the or each communications link allocated to or associated with the platform applications; identifying, for each platform application, data to be transmitted thereby to a recipient node, and comparing a bandwidth requirement of data to be transmitted with a current available bandwidth of the respective communications link allocated thereto or associated therewith; in the event that, as a result of the comparing, a current available bandwidth of a communications link is determined to be insufficient in relation to the bandwidth requirement of a specified platform application, generating information data and transmitting the information data to the specified platform application, or a quality of service interface associated therewith; adapting, by the specified platform application, or the quality of service interface associated therewith, upon receipt of the information data, at least one parameter of its respective application data to the current available bandwidth of its respective communications link for transmission to a recipient node.

First claim

1 . An apparatus for data communications in respect of a moving platform, the apparatus comprising a plurality of platform applications, a communications system, and a data management module, the communications system being configured to cause data from each said platform application to be transmitted, via wireless data communication, to at least one recipient node via a respective one or more allocated or associated communication links of a plurality of supported communications links, said data management module being configured to:
receive performance data indicative of a current available bandwidth of the or each communications link allocated to or associated with said platform applications; for each said platform application, identify data to be transmitted thereby to a recipient node, and compare a bandwidth requirement of data to be transmitted with a current available bandwidth of the respective communications link allocated thereto or associated therewith; and in the event that, as a result of said comparing, a current available bandwidth of a communications link is determined to be insufficient in relation to the bandwidth requirement of a specified platform application, generate information data and transmit said information data to said specified platform application, or a quality of service interface associated therewith; wherein each said platform application, or a quality of service interface associated therewith, is configured, upon receipt of said information data, to adapt at least one parameter of its respective application data to said current available bandwidth of its respective communications link for transmission to a recipient node.

2 . The apparatus according to claim 1 , wherein said data management module is configured to use said performance data to identify a change in available bandwidth of said communications link, determine if said current available bandwidth is within an acceptable bandwidth range of said platform application and, if so, generate a control signal including said information data, said control signal being configured, upon receipt thereof by said specified platform application, to cause said specified platform application to adapt at least one parameter of its respective application data to said current available bandwidth of its respective communications link for transmission to a recipient node.

3 . The apparatus according to claim 1 , wherein said data management module is configured to provide, to said specified platform application, data indicative of said current available bandwidth, thereby enabling said platform application to adapt said at least one parameter of said application to said current available bandwidth.

4 . The apparatus according to claim 1 , wherein said data management module is configured to provide, to a Quality of Service interface associated with said specified platform application, data indicative of said current available bandwidth.

5 . The apparatus according to claim 1 , wherein said performance data comprises current bandwidth data in respect of said respective communications link.

6 . The apparatus according to any of claim 1 , wherein said performance data comprises a performance indicator representative of a current status of said respective communications link.

7 . The apparatus according to claim 6 , wherein said performance indicator comprises one of a plurality of discrete statuses.

8 . The apparatus according to claim 1 , wherein adapting said at least one parameter of said platform application data comprises compressing said data.

9 . The apparatus according to claim 1 , wherein adapting said at least one parameter of said platform application data comprises adapting the transmission rate of said platform application from which said data is received.

10 . The apparatus according to claim 1 , wherein adapting said at least one parameter of said platform application data comprises selecting a type or portion of said data to be transmitted.

11 . The apparatus according to claim 1 , comprising a bandwidth monitoring module for monitoring the current available bandwidth of the respective one or more communications links allocated or associated with said plurality of platform applications, wherein said data management module is configured to receive data from said bandwidth monitoring module and detect a change in current available bandwidth of said one or more communications links.

12 . The apparatus according to claim 11 , wherein said data management module is further configured to determine if said current available bandwidth is within an acceptable bandwidth range of each respective platform application and, if so, generate a control signal including said information data, said control signal being configured, upon receipt thereof by said specified platform application, to cause said specified platform application to adapt at least one parameter of its respective application data to said current available bandwidth of its respective communications link for transmission to a recipient node.

13 . A method of management of data communications in respect of a moving platform comprising a plurality of platform applications and a communications system, the communications system being configured to cause data from each said platform application to be transmitted, via wireless data communication, to at least one recipient node via a respective one or more allocated or associated communication links of a plurality of supported communications links, the method comprising:
receiving performance data indicative of a current available bandwidth of the or each communications link allocated to or associated with said platform applications; identifying, for each platform application, data to be transmitted thereby to a recipient node, and comparing a bandwidth requirement of data to be transmitted with a current available bandwidth of the respective communications link allocated thereto or associated therewith; in the event that, as a result of said comparing, a current available bandwidth of a communications link is determined to be insufficient in relation to the bandwidth requirement of a specified platform application, generating information data and transmitting said information data to said specified platform application, or a quality of service interface associated therewith; adapting, by said specified platform application, or said quality of service interface associated therewith, upon receipt of said information data, at least one parameter of its respective application data to said current available bandwidth of its respective communications link for transmission to a recipient node.
