Abstract

Claims (63)

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

obtaining, by a first device, an address of the target device, wherein a size of the obtained address of the target device is larger than a size of the address part of the frame;

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

allocating the first address part in the address part of the frame, wherein the first address part partially or completely fills the address part of the frame;

allocating at least a portion of payload data in the payload data part of the frame; and

transmitting the frame to the target device,

wherein the first address part allocated in the address part of the frame is indicative of a first part of a device address of target device itself and the second address part allocated in the payload data part of the frame is an entire remaining portion of the address of the target device and is indicative of a second part of the device address of the target device itself, and

wherein the first address part for each target device that exchanges data with the first device is different from the first address part of any other target device that exchanges data with the first device.

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 accommodates the address part of the frame.

3. The method of claim 1 , wherein the first address part completely fills the address part of the frame so that no unused spare part within the address part of the frame remains.

4. The method of claim 1 , wherein the frame is transmitted over a shared channel to the target device.

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

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 system comprising a first device for addressing a frame to a target device, the frame being one of a protocol that defines the frame as having an address part and a payload data part, the first device being configured to:

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

allocate the first address part in the address part of the frame, wherein the first address part partially or completely fills the address part of the frame;

allocate at least a portion of payload data in the payload data part of the frame;

allocate the second address part in the payload data part of the frame; and

transmit the frame to the target device,

wherein the first address part allocated in the address part is indicative of a first part of a device address of target device itself and the second address part allocated in the payload data part is an entire remaining portion of the address of the target device and is indicative of a second part of the device address of the target device itself, and

wherein the first address part for each target device that exchanges data with the first device is different from the first address part of any other target device that exchanges data with the first device.

8. The first 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 first device.

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

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

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

12. A method of receiving a frame over a shared channel, the frame being one of a protocol that defines the frame as having an address part and a payload data part, the frame including an address of a target device that is split into a first target address part and a second target address part, the first target address part being allocated in the address part of the frame, and the second target address part being allocated in the payload data part of the frame, wherein the first address part allocated in the address part is indicative of a first part of a device address of target device itself and the second address part allocated in the payload data part is an entire remaining portion of the address of the target device and is indicative of a second part of the device address of the target device itself, and

the method comprising:

receiving the address part of the frame together with the payload part of the frame;

determining whether the first target address part allocated in the received address part of the frame matches the first target address part of the target device;

if the first target address part allocated in the received address part does not match the first target address part of the target device, perform at least one of i) putting communication equipment handling the receiving of the address part of the frame into a power-save mode and ii) turning off circuitry for receiving wireless radio signals of the communication equipment handling the receiving of the address part of the frame; and

if the first target address part allocated in the received address part matches the first target address part of the target device:

extracting the second target address part from the received payload data part,

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

if the extracted second target address part does not match the second target address part of the target device, perform at least one of i) putting the communication equipment handling the receiving of the payload part of the frame into the power-save mode, and ii) turning off the circuitry for receiving wireless radio signals of the communication equipment handling the receiving of the payload part of the frame.

13.
