Abstract

Addressing a frame to a target device, the frame being one of a protocol that defines the frame with at least an address part and a payload data part, including obtaining an address of the target device, splitting the address into a first part and a second part, allocating the first part in the address part of the frame, and allocating the second part in the payload data part of the frame.

Claims

1. A method of addressing a frame to a target device, the frame being one of a protocol that defines the frame with at least an address part and a payload data part, the method comprising the steps of:

obtaining an address of the target device;

splitting the address into a first part and a second part;

allocating the first part in the address part of the frame; and

allocating the second part in the payload data part of the frame;

2. The method of claim 1, wherein the address of the target device is represented by an integer number (m) of bytes and a smaller integer number (n) of bytes fully accommodate the address part of the frame.

3. The method of claim 1, wherein the first part completely fills the address part of the frame.

4. The method of claim 1, further comprising transmitting a completed frame over a shared channel to the target device.

5. The method of claim 1, wherein a plurality of frames are transmitted to plurality of target devices over a shared channel, one frame being addressed to at least one target device.

6. The method of claim 1, wherein the protocol is any one of EnOcean™

, Dash7™

, OneNet™

, ANT™

, Bluetooth™

, Z-Wave™

, Zigbee™

, WirelessHart™

, 6LoWPAN™

, MiWi™

, IEEE 802.15.4, and IEEE 802.11 (WiFi).

7. A device for addressing a frame to a target device, the frame being one of a protocol that defines the frame with at least an address part and a payload data part, the device being configured to:

obtain an address of the target device;

split the address into a first part and a second part;

allocate the first part in the address part of the frame; and

allocate the second part in the payload data part of the frame.

9. The device of claim 7, further comprising a processing unit and a memory unit, said memory unit storing code so as to configure said processing unit to implement the functionalities of the device.

10. The device of claim 7, further comprising a communication unit for establishing communication over a shared channel.

11. The device of claim 7, further comprising an internal power source.

12. The device of claim 7, further being configured as a data collection device as part of distributed data acquisition equipment, and being configured to transmit a frame to a data acquisition unit.

23. A system for distributed data acquisition comprising:

at least one device of claim 12; and

a device of receiving a frame over a shared channel, the frame being one of a protocol that defines for the frame at least an address part and a payload data part, an address of a target device being split into a first part and a second part, the first part being allocated in the address part and the second part being allocated in the payload data part, the device being configured to;

receive the address part of a frame;

process the received address part for determining whether the first part allocated in the received address part matches a first part of a target device address;

receive the payload data part of the frame;

if the first part allocated in the received address part matches the first part of the target device address extract the second part from the received payload data part; and

determine that the frame is addressed to the target device if the extracted second part matches a second part of the target device address,

wherein the device is further configured as a data acquisition device as part of distributed data acquisition equipment, comprising a sensor unit for acquiring data and being configured to receive a frame from a data collection unit.

8. (canceled)

13. A method of receiving a frame over a shared channel, the frame being one of a protocol that defines for the frame at least an address part and a payload data part, an address of a target device being split into a first part and a second part, the first part being allocated in the address part and the second part being allocated in the payload data part, the method comprising the steps of:

receiving the address part of a frame;

processing the received address part for determining whether the first part allocated in the received address part matches a first part of a target device address;

receiving the payload data part of the frame;

if the first part allocated in the received address part matches the first part of the target device address, extracting the second part from the received payload data part; and

determining that the frame is addressed to the target device if the extracted second part matches a second part of the target device address.

14. The method of claim 13, further comprising a step of putting communication equipment handling the receiving of the address part and the payload data part of the frame into a power-save mode if it is determined that the first part allocated in the received address part does not match the first part of a target device address.

15. The method of claim 13, further comprising a step of aborting the method if it is determined that the first part allocated in the received address part does not match the first part of a target device address.

16. The method of claim 13, wherein the address part and the payload data part are received together during receiving the frame.

17. A device of receiving a frame over a shared channel, the frame being one of a protocol that defines for the frame at least an address part and a payload data part, an address of a target device being split into a first part and a second part, the first part being allocated in the address part and the second part being allocated in the payload data part, the device being configured to:

receive the address part of a frame;

process the received address part for determining whether the first part allocated in the received address part matches a first part of a target device address;

receive the payload data part of the frame;

if the first part allocated in the received address part matches the first part of the target device address, extract the second part from the received payload data part; and

determine that the frame is addressed to the target device if the extracted second part matches a second part of the target device address.

19. The device of claim 17, further comprising a processing unit and a memory unit, said memory unit storing code so as to configure said processing unit to implement the functionalities of the device.

20. The device of claim 17, further comprising a communication unit for establishing communication over a shared channel.

21. The device of claim 17, further comprising an internal power source.

22. The device of claim 17, further being configured as a data acquisition device as part of distributed data acquisition equipment, comprising a sensor unit for acquiring data and being configured to receive a frame from a data collection unit.
