Abstract

A controller arrangement comprising a transceiver capable of communication via a wireless communication network, a controller arranged to control a physical entity at which the controller arrangement is arranged, and an interface between the transceiver and the controller is disclosed. The transceiver is arranged to provide information via the interface about present or imminent interrupts in the communication via the wireless network. The controller is arranged to operate in at least a first state when the information indicates that no interrupts are present or imminent, wherein the first state includes closed loop control from a remote entity via the wireless communication network, and a second state when the information indicates that interrupts are present or imminent, wherein the second state includes autonomous control operations by the controller. A method and computer program are also disclosed.

First claim

The invention claimed is:

1. A controller arrangement comprising
a transceiver capable of communication via a wireless communication network;
a controller arranged to control a physical entity at which the controller arrangement is arranged; and
an interface between the transceiver and the controller,
wherein
the transceiver is arranged to provide information via the interface about present or imminent interrupts in the communication via the wireless network, and
the controller is arranged to operate in at least a first state when the information indicates that no interrupts are present or imminent, wherein the first state includes closed loop control from a remote entity via the wireless communication network, and a second state when the information indicates that interrupts are present or imminent, wherein the second state includes autonomous control operations by the controller,
wherein the wireless communication network comprises a cellular communication network and the transceiver provides the information about present or imminent interrupts in the communication based on mobility management information associated with the wireless communication network, and
wherein the mobility management information associated with the wireless communication network comprises any of:
measurement execute instruction;
handover execute instruction;
measurement completed;
handover completed;
release connection with redirect instruction;
release connection with redirect completed;
connection reestablishment instruction; and
connection reestablishment completed.

2. The controller arrangement of claim 1 , wherein the mobility management information associated with the wireless communication network comprises instructions provided from a node of the wireless communication network.

3. The controller arrangement of claim 1 , wherein the mobility management information associated with the wireless communication network comprises indications on a completed task provided from the transceiver.

4. The controller arrangement of claim 1 , wherein the wireless communication network comprises a short range communication network and the transceiver provides the information about present or imminent interrupts in the communication based on connection state information in relation to an access point of the wireless communication network.

5. The controller arrangement of claim 4 , wherein the connection state information in relation to the access point of the wireless communication network comprises any of:
in-synchronization with the access point;
out-of-synchronization with the access point;
scanning for access points ongoing;
reconnection to an access point ongoing;
authentication process; and
association process.

6. The controller arrangement of claim 1 , wherein the second state comprises:
a first sub-state when the information indicates that interrupts are present or imminent during predetermined periods, wherein the first sub-state includes open loop control from the remote entity via the wireless communication network in conjunction with the autonomous control operations by the controller, and
a second sub-state when the information indicates that interrupts are present or imminent during an unknown time, wherein the second sub-state includes the autonomous control operations by the controller without control from the remote entity via the wireless communication network.

7. The controller arrangement of claim 6 , wherein the first sub-state is when a duration of the interrupt is known and below a threshold, and the second sub-state is when the duration of the interrupt is unknown or above the threshold.

8. A controller arrangement comprising:
a transceiver capable of communication via a wireless communication network;
a controller arranged to control a physical entity at which the controller arrangement is arranged; and
an interface between the transceiver and the controller,
wherein
the transceiver is arranged to provide information via the interface about present or imminent interrupts in the communication via the wireless network, and
the controller is arranged to operate in at least a first state when the information indicates that no interrupts are present or imminent, wherein the first state includes closed loop control from a remote entity via the wireless communication network, and a second state when the information indicates that interrupts are present or imminent, wherein the second state includes autonomous control operations by the controller,
wherein the second state comprises:
a first sub-state when the information indicates that interrupts are present or imminent during predetermined periods, wherein the first sub-state includes open loop control from the remote entity via the wireless communication network in conjunction with the autonomous control operations by the controller, and
a second sub-state when the information indicates that interrupts are present or imminent during an unknown time, wherein the second sub-state includes the autonomous control operations by the controller without control from the remote entity via the wireless communication network, and
wherein the first sub-state is when the information indicates that the transceiver is to be connected to the same node of the wireless communication network after the interrupt as before the interrupt, and the second sub-state is when the information indicates that the transceiver is to be connected to another node of the wireless communication network after the interrupt than before the interrupt.

9. A method of a controller arrangement comprising a transceiver capable of communication via a wireless communication network and a controller arranged to control a physical entity at which the controller arrangement is arranged, the method comprising:
providing information by the transceiver to the controller about present or imminent interrupts in the communication via the wireless network; and
operating the controller in at least a first state when the information indicates that no interrupts are present or imminent, wherein the first state includes closed loop control from a remote entity via the wireless communication network, and a second state when the information indicates that interrupts are present or imminent, wherein the second state includes autonomous control operations by the controller,
wherein the providing of the information about present or imminent interrupts in the communication is based on mobility management information associated with the wireless communication network, and
wherein the mobility management information associated with the wireless communication network comprises any of:
measurement execute instruction;
handover execute instruction;
measurement completed;
handover completed;
release connection with redirect instruction;
release connection with redirect completed;
connection reestablishment instruction; and
connection reestablishment completed.

10. The method of claim 9 , wherein the mobility management information associated with the wireless communication network comprises instructions provided from a node of the wireless communication network.

11. The method of claim 9 , wherein the mobility management information associated with the wireless communication network comprises indications on a completed task provided from the transceiver.

12. The method of claim 9 , wherein the wireless communication network comprises a short range communication network and providing of the information by the transceiver about present or imminent interrupts in the communication is based on connection state information in relation to an access point o
