Abstract

A server receives sensor information from a wireless device and provides control signals based on the sensor information to the wireless device for enabling the device to perform a control task. The server receives an estimate of imminent connection state of the wireless device. Upon the state indicating a connection quality parameter to have a quality below a first threshold, the server provides an information package to be sent to the wireless device for enabling the device to perform an increased part of the control task locally at the device. Upon the state indicating the connection quality parameter to have a quality above a second threshold, the server provides an information package to be sent to the wireless device for enabling the device to be relieved from performing at least a part of the control task by the server providing increased aid in performing the control task.

First claim

The invention claimed is:

1. A server that is configured to connect to a wireless device via a wireless communication network and that is capable of receiving sensor information from the wireless device and providing control signals based on at least the sensor information to the wireless device for enabling the wireless device to perform a control task, the server comprising:
one or more processing circuits configured to:
receive an estimate of imminent connection state of the wireless device;
upon the estimate of the imminent connection state indicating a connection quality parameter to have a quality below a first threshold, provide an information package comprising one or more of a set of computer executable instructions, a control parameter set, and a control model to be sent to the wireless device for enabling the wireless device to perform at least an increased part of the control task locally at the wireless device and to adapt control setup based thereon, and
upon the estimate of the imminent connection state indicating the connection quality parameter to have a quality above a second threshold, provide an information package to be sent to the wireless device for enabling the wireless device to be relieved from performing at least a part of the control task, or to improve control performance, by the server providing increased aid in performing the control task.

2. The server of claim 1 , wherein the estimate of the imminent connection state is based on at least one or more radio channel parameters at the wireless device.

3. The server of claim 2 , wherein the radio channel parameters comprise one or more of
signal-to-interference-and-noise ratio;
signal strength;
uplink throughput;
downlink throughput;
latency;
used radio access technology; and
one or more of the above for a neighbouring cell.

4. The server of claim 1 , wherein the estimate of the imminent connection state is based on at least one or more spatial parameters of the wireless device.

5. The server of claim 4 , wherein the spatial parameters comprise one or more of
a position of the wireless device; and
a speed of the wireless device.

6. The server of claim 1 , wherein the wireless communication network is a cellular network and the estimate of the imminent connection state is based on information indicating whether a handover operation is imminent.

7. The server of claim 1 , wherein the control signals are further based on at least sensor information from at least a further device being in connection with the server.

8. The server of claim 1 wherein the control task comprises controlling a vehicle.

9. The server of claim 8 , wherein the information package to be sent to the wireless device for enabling the wireless device to perform at least an increased part of the control task locally comprises information about other vehicles.

10. A method of a server connected via a wireless communication network to a wireless device, the method comprising:
receiving sensor information from the wireless device;
providing control signals based on at least the sensor information to the wireless device for enabling the wireless device to perform a control task;
receiving an estimate of imminent connection state of the wireless device; and
providing a first information package or a second information package to be sent to the wireless device depending respectively on whether the estimated imminent connection state indicates that a connection quality parameter has a quality below a first threshold or above a second threshold;
wherein the first information package comprises one or more of a set of computer executable instructions, a control parameter set, and a control model to be sent to the wireless device for enabling the wireless device to perform at least an increased part of the control task locally at the wireless device and to adapt control setup based thereon;
wherein the second information package is an information package for enabling the wireless device to be relieved from performing at least a part of the control task, or to improve control performance, by the server providing increased aid in performing the control task.

11. The method of claim 10 , wherein the estimate of the imminent connection state is based on at least one or more radio channel parameters at the wireless device.

12. The method of claim 11 , wherein the radio channel parameters comprise one or more of
signal-to-interference-and-noise ratio;
signal strength;
uplink throughput;
downlink throughput;
latency;
used radio access technology; and
one or more of the above for a neighbouring cell.

13. The method of claim 10 , wherein the estimate of the imminent connection state is based on at least one or more spatial parameters of the communication device.

14. The method of claim 13 , wherein the spatial parameters comprise one or more of
a position of the wireless device; and
a speed of the wireless device.

15. The method of claim 10 , wherein the wireless communication network is a cellular network, and the estimate of the imminent connection state is based on information indicating whether a handover operation is imminent.

16. The method of claim 10 , wherein the control signals are further based on at least sensor information from at least a further device being in connection with the server.

17. The method of claim 10 , wherein the control task comprises controlling a vehicle.

18. A non-transitory computer readable medium for controlling a server connected to a wireless device via a wireless communication network and capable of receiving sensor information from the wireless device and providing control signals based on at least the sensor information to the wireless device for enabling the wireless device to perform a control task, the non-transitory computer readable medium having stored thereon software instructions which, when run on a processor of the server, causes the server to:
receive sensor information from the wireless device;
provide control signals based on at least the sensor information to the wireless device for enabling the wireless device to perform a control task;
receive an estimate of an imminent connection state of the wireless device; and
provide a first information package or a second information package to be sent to the wireless device depending respectively on whether the estimated imminent connection state indicates that a connection quality parameter has a quality below a first threshold or above a second threshold;
wherein the first information package comprises one or more of a set of computer executable instructions, a control parameter set, and a control model to be sent to the wireless device for enabling the wireless device to perform at least an increased part of the control task locally at the wireless device and to adapt control setup based thereon;
wherein the second information package is an information package for enabling the wireless device to be relieved from performing at least a part of the control task, or to improve control performance, by the server providing increased aid in performing the control task.
