Abstract

A server is connected via a wireless communication network to be capable of receiving sensor information from a wireless device and provide 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 is arranged to receive an estimate of imminent connection state of the wireless device and adapt operation such that upon the estimated imminent connection state indicates 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 wireless device to perform at least an increased part of the operation task locally at the wireless communication device, and upon the estimated imminent connection state indicates 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 wireless device to be relieved from performing at least a part of the operation task by the server providing increased aid in performing the control task. The wireless device, methods and computer programs are also disclosed.

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 cause the server to receive an estimate of imminent connection state of the wireless device and adapt operation such that:
in response to the estimated imminent connection 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 wireless device to perform at least an increased part of the control task locally at the wireless device which involves the wireless device turning on at least one additional sensor; and
in response to the estimated imminent connection 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 wireless 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 so as to enable the wireless device to turn off the at least one additional sensor.

2. The server of claim 1 , wherein the estimated 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 neighboring cell.

4. The server of claim 1 , wherein the estimated 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 comprises 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 information package provided from the server for enabling the wireless device to perform at least an increased part of the control task locally comprises one or more of:
a set of computer executable instructions;

a control model.

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

8. 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.

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

10. The server of claim 9 , wherein the information package comprises information about other vehicles.

11. The server of claim 1 , wherein the control signals indicate a full or partial control model or control parameter set, wherein the control task comprises controlling a vehicle based on the full or partial control model or control parameter set, wherein the information package for enabling the wireless device to perform at least an increased part of the control task locally comprises an information package for enabling the wireless device to update the full or partial control model or control parameter set locally at the wireless device, and wherein the information package for enabling the wireless device to be relieved comprises an information package for enabling the wireless device to be relieved from updating the full or partial control model or control parameter set locally at the wireless device by the server providing increased aid in remotely updating the full or partial control model of control parameter set.

12. 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 adapting operation such that:
in response to the estimated imminent connection state indicating a connection quality parameter to have a quality below a first threshold, providing an 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 at the wireless device which involves the wireless device turning on at least one additional sensor; and
in response to the estimated imminent connection state indicating the connection quality parameter to have a quality above a second threshold, providing 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 by the server providing increased aid in performing the control task so as enable the wireless device to turn off the one least one additional sensor.

13. The method of claim 12 , wherein the estimated imminent connection state is based on at least one or more radio channel parameters at the wireless device.

14. The method of claim 13 , wherein the radio channel parameters comprise one or more of:
