Abstract

A mobile communication system comprises: a mobile platform (1) having a plurality of interfaces (2) to a respective plurality of mobile communication networks (6), and a router (5) for selectively connecting one or more communications devices (4) within the mobile platform (1) to one or more of the interfaces (2), for communication over the respective mobile communication networks (6); and a central core (10), common to each of the mobile communication networks (6), including a resource manager (11) arranged to allocate communication resources to the link interfaces (2); wherein the resource manager (11) is responsive to resource requests (S3) from the mobile platform (1) and to network conditions in the mobile communication networks (6).

Claims

1. A mobile communication system, comprising:

a mobile platform having a plurality of interfaces to a respective plurality of mobile communication networks, and a router for selectively connecting one or more communications devices within the mobile platform to one or more of the interfaces, for communication over the respective mobile communication networks; and

a central core common to each of the mobile communication networks, comprising a policy master arranged to determine resource requirements within the mobile communication networks in accordance with one or more defined policies and a resource manager arranged to allocate resources to the mobile communication networks in response to resource requests from the router and to resource requests from the policy master,

wherein the resource manager is arranged to control which of the interfaces are active on the mobile platform such that they are connected to a respective one of the mobile communication networks, thereby controlling the respective mobile communication network'"'"'s connectivity to the router.

2. The system of claim 1, wherein the resource manager is arranged to vary the communication resources available through one or more of the interfaces.

3. The system of claim 1, wherein the resource manager is arranged to vary the allocation of communication resources dynamically.

4. The system of claim 1, wherein the defined policies comprise one or more rules or heuristics based on one or more of:

the nature of the resource requests, the conditions or available capacity within the mobile communication networks, the current or future position of the mobile platform, and cost, energy, latency or efficiency requirements.

5. The system of claim 1, wherein the policy master is responsive to network metrics and/or parameters of the mobile communications networks.

6. The system of claim 5, wherein the network metrics and/or parameters are collected and provided by a Network Management System Station.

7. The system of claim 1, wherein the router is able to select different ones of the interfaces for uplink and downlink communications.

8. The system of claim 1, wherein the router is able to select more than one of the interfaces for simultaneous communications.

9. The system of claim 1, wherein the mobile platform includes a local network for connecting a plurality of communication devices to the router.

10. The system of claim 9, wherein the local network comprises a wireless and/or wired network.

11. The system of claim 1, wherein the mobile platform comprises an aeronautical or maritime platform.

12. A method of operating the system of claim 1, comprising:

a) sending said resource request from the router to the resource manager in response to traffic demand within the mobile platform; and

b) allocating, by the resource manager, said communication resources to the link interfaces.

13. A method of operating the system of claim 1, comprising:

a) detecting, by the policy master, a change in communication resource requirements within the mobile platform;

b) requesting, by the policy master to the resource manager, a corresponding variation in communication resources; and

c) varying, by the resource manager, the allocation of said communication resources to the interfaces.

14. A method of operating a mobile communication system, the system comprising:

a mobile platform having a plurality of interfaces to a respective plurality of mobile communication networks, and a router for selectively connecting one or more communications devices within the mobile platform to one or more of the interfaces, for communication over the respective mobile communication networks; and

a central core common to each of the mobile communication networks, comprising a policy master and a resource manager;

the method comprising;

a) at the policy master, determining resource requirements within the mobile communication networks in accordance with one or more defined policies;

b) at the resource manager, allocating resources to the mobile communication networks in response to resource requests from the router and to resource requests from the policy master; and

c) at the resource manager, controlling which of the interfaces are active on the mobile platform, such that they are connected to a respective one of the mobile communication networks, thereby controlling the respective mobile communication network'"'"'s connectivity to the router.

15. The method of claim 14, further comprising:

d) sending said resource request from the router to the resource manager in response to traffic demand within the mobile platform; and

e) allocating, by the resource manager, said communication resources to the link interfaces.

16. The method of claim 14, further comprising:

d) detecting, by the policy master, a change in communication resource requirements within the mobile platform

e) requesting, by the policy master to the resource manager, a corresponding variation in communication resources; and

f) varying, by the resource manager, the allocation of said communication resources to the interfaces.
