Abstract

A method for operating a local network for a terminal device by a first communication device of a first motor vehicle is provided. A first mobile network connection is set up between the first motor vehicle and a network external to the motor vehicle Using the first communication device. The local network is created for the terminal device as a function of the first mobile network connection. A current first state of charge of a first electrical energy storage unit of the first motor vehicle is determined by the first communication device and the local network is created as a function of the determined first state of charge that is determined.

First claim

1 - 8 . (canceled)

9 . A method, comprising:
determining, by a first communication device of a first motor vehicle, a current first state of charge of a first electrical energy storage unit of a first motor vehicle; generating a first provisioning forecast for creating a local network by the first communication device by
determining a current first energy requirement of the first motor vehicle;
storing, in a first storage device of the first communication device, the determined current first energy requirement; and
determining, as a function of a plurality of stored first energy requirements that include the determined first energy requirement, an average first energy requirement, wherein the first provisioning forecast is generated as a function of the average first energy requirement;
establishing a first mobile network connection between the first communication device and a network external to the motor vehicle; determining, by the first communication device, whether to create a local network with at least one terminal device based on the determined current first state of charge of the first electrical energy storage unit and the first provisioning forecast; and creating, by the first communication device, the local network when it is determined, based on the determined current first state of charge of the first electrical energy storage unit and the first provisioning forecast, to create the local network, wherein the at least one terminal device is connected to the network external to the motor vehicle via the local network, the first communication device, and the first mobile network connection.

10 . The method of claim 9 , wherein the local network is created in a parked state of the first motor vehicle.

11 . The method of claim 9 , wherein the local network is created as a function of a first connection quality of the first mobile network connection as determined by the first communication device.

12 . The method of claim 9 , wherein the local network is created as a function of a first ignition state of the first motor vehicle as determined by the first communication device.

13 . The method of claim 9 , wherein the local network is used by a plurality of of terminal devices that include the at least one terminal device.

14 . A method, comprising:
determining, by a first communication device of a first motor vehicle, a first state of charge of a first electrical energy storage unit of the first motor vehicle; determining, by a second communication device of a second motor vehicle, a second state of charge of a second electrical energy storage unit of the second motor vehicle; determining, based on the determined first and second states of charge, whether the first communication device or the second communication device establishes a local network; establishing a first mobile network connection between the first communication device and a network external to the motor vehicle; establishing a second mobile network connection between the second communication device and the network external to the motor vehicle; and creating, by the determined one first and second communication devices, the local network, wherein the at least one terminal device is connected to the network external to the motor vehicle via the local network, the determined one of the first and communication devices, and a corresponding one of the first and second mobile network connections.

15 . The method of claim 14 , wherein the determined one of the first and second communication devices is the first communication device, wherein the second communication device creates the local network when the first state of charge reaches a predetermined state of charge or the first motor vehicle leaves predetermined surroundings for the local network.

16 . A system, comprising:
a motor vehicle that includes a communication device and an electrical energy storage unit; and at least one terminal device, wherein the communication device is configured to
determine a current first state of charge of a first electrical energy storage unit of a first motor vehicle;
generate a first provisioning forecast for creating a local network by the first communication device by
determining a current first energy requirement of the first motor vehicle;
storing, in a first storage device of the first communication device, the determined current first energy requirement; and
determining, as a function of a plurality of stored first energy requirements that include the determined first energy requirement, an average first energy requirement, wherein the first provisioning forecast is generated as a function of the average first energy requirement;

establish a first mobile network connection between the first communication device and a network external to the motor vehicle;
determine whether to create a local network with at least one terminal device based on the determined current first state of charge of the first electrical energy storage unit and the first provisioning forecast; and
create the local network when it is determined, based on the determined current first state of charge of the first electrical energy storage unit and the first provisioning forecast, to create the local network,
wherein the at least one terminal device is connected to the network external to the motor vehicle via the local network, the first communication device, and the first mobile network connection.
