Communications method
First Claim
1. A method of providing connectivity to a vehicle, comprising at a first device aboard the vehicle:
- establishing at least one first connection with at least one first network, said at least one first connection allowing communication with a second device not aboard the vehicle and remote from said first device;
transmitting via said at least one first connection an allocation request to said second device;
receiving via said at least one first connection an allocation response from said second device, said allocation response indicating a first authentication device from a plurality of authentication devices not aboard the vehicle and remote from said first device, wherein said allocation response further indicates a third authentication device of said plurality of authentication devices;
establishing a second connection with a second network and authenticating said first device on the second network using said first authentication device, the establishing a second connection comprising switching between a first state in which a first modem of said first device uses an authentication device co-located with the first device to a second state in which said first modem uses said first authentication device, wherein in said second state a second modem of said first device uses a second authentication device co-located with the first device, the authenticating said first device on the network comprising transmitting authentication data between said first device and said first authentication device via said at least one first connection; and
establishing a third connection with a third network and authenticating said first device on said third network using said third authentication device, wherein establishing the third connection comprises switching to a third state in which said second modem uses said third authentication device.

14. An apparatus for providing connectivity to a vehicle, comprising a first device aboard the vehicle, the first device being arranged to:
-
establish at least one first connection with at least one network, said at least one first connection allowing communication with a second device not aboard the vehicle and remote from said first device; transmit via said at least one first connection an allocation request to said second device; receive via said at least one first connection an allocation response from said second device, said allocation response indicating a first authentication device from a plurality of authentication devices remote from said first device and not aboard the vehicle, wherein said allocation response further indicates a third authentication device of said plurality of authentication devices; establish a second connection with a second network by switching between a first state in which a first modem of said first device uses an authentication device co-located with the first device to a second state in which said first modem uses said first authentication device, wherein in said second state a second modem of said first device uses a second authentication device co-located with the first device, and authenticating said first device on the second network using said first authentication device by transmitting authentication data between said first device and said first authentication device via said at least one first connection; and establish a third connection with a third network by switching to a third state in which said second modem uses said third authentication device, and authenticate said first device on said third network using said third authentication device.

15. A non-transitory computer readable medium carrying a computer program comprising computer readable instructions configured to cause a processor of a first device aboard a vehicle to carry out a method of providing connectivity to the vehicle, comprising:
-
establishing at least one first connection with at least one first network, said at least one first connection allowing communication with a second device not aboard the vehicle and remote from said first device; transmitting via said at least one first connection an allocation request to said second device; receiving via said at least one first connection an allocation response from said second device, said allocation response indicating a first authentication device from a plurality of authentication devices remote from said first device and not aboard the vehicle, wherein said allocation response further indicates a third authentication device of said plurality of authentication devices; establishing a second connection with a second network and authenticating said first device on the second network using said first authentication device, the establishing a second connection comprising switching between a first state in which a first modem of said first device uses an authentication device co-located with the first device to a second state in which said first modem uses said first authentication device, wherein in said second state a second modem of said first device uses a second authentication device co-located with the first device, the authenticating said first device on the network comprising transmitting authentication data between said first device and said first authentication device via said at least one first connection; and establishing a third connection with a third network and authenticating said first device on said third network using said third authentication device, wherein establishing the third connection comprises switching to a third state in which said second modem uses said third authentication device.

16. A computer apparatus aboard a vehicle for providing connectivity to the vehicle, comprising:
-
a memory storing processor readable instructions; and a processor arranged to read and execute instructions stored in said memory;
wherein said processor readable instructions comprise instructions arranged to control the computer apparatus to carry out a method of providing connectivity to the vehicle, comprising;establishing at least one first connection with at least one first network, said at least one first connection allowing communication with a second device not aboard the vehicle and remote from the computer apparatus; transmitting via said at least one first connection an allocation request to said second device; receiving via said at least one first connection an allocation response from said second device, said allocation response indicating a first authentication device from a plurality of authentication devices remote from the computer apparatus and not aboard the vehicle, wherein said allocation response further indicates a third authentication device of said plurality of authentication devices; establishing a second connection with a second network and authenticating said computer apparatus on the second network using said first authentication device, the establishing a second connection comprising switching between a first state in which a first modem of said first device uses an authentication device co-located with the first device to a second state in which said first modem uses said first authentication device, wherein in said second state a second modem of said first device uses a second authentication device co-located with the first device, the authenticating said computer apparatus on the network comprising transmitting authentication data between said computer apparatus and said first authentication device via said at least one first connection; and establishing a third connection with a third network and authenticating said first device on said third network using said third authentication device, wherein establishing the third connection comprises switching to a third state in which said second modem uses said third authentication device.
