Abstract

Disclosed is a method for requesting data from a set of remote units in a network, the method comprising: defining an Asynchronous Ubiquitous Protocol, the Asynchronous Ubiquitous Protocol comprising a schedule of a plurality of time slots, each time slot defined by a distinct start time and end time pair; broadcasting transmitting instructions to the set of remote units, the transmitting instructions comprising the Asynchronous Ubiquitous Protocol and selection instructions for selecting a time slot from the Asynchronous Ubiquitous Protocol to use for data transmission; and, receiving data transmitted from a remote unit in the set of remote units in accordance with the transmitting instructions.

Claims

1. A method for requesting data from a set of remote units in a network, the method comprising:

defining an Asynchronous Ubiquitous Protocol, the Asynchronous Ubiquitous Protocol comprising a schedule of a plurality of time slots, each time slot defined by a distinct start time and end time pair, the start time and end time pairs defining a set of non-overlapping time slots within which data may be transmitted, wherein the plurality of time slots of the schedule are unallocated time slots eligible to be selected by remote units;

broadcasting transmitting instructions to the set of remote units, the transmitting instructions comprising the Asynchronous Ubiquitous Protocol and selection instructions, the selection instructions specifying a procedure to be used by the remote units to select time slots from the Asynchronous Ubiquitous Protocol to use for data transmission; and

receiving data transmitted from a remote unit in the set of remote units in accordance with the transmitting instructions, the data indicating an emergency event or occurrence.

2. The method of claim 1 further comprising transmitting an acknowledgement message to the remote unit.

3. The method of claim 1, wherein the number of times slots and the duration of the time slots are dynamic and dependent on the performance of the communication network.

4. The method of claim 1 further comprising:

monitoring one or more conditions of the network, and wherein the Asynchronous Ubiquitous Protocol is defined based on the monitored one or more conditions.

5. The method of claim 4 wherein the one or more conditions comprise one of:

an increased rate of data retransmission;

an increase in the number of poll requests from remote units; and

an increase in the number of timeslots within which data is not included.

6. The method of claim 1 wherein receiving data transmitted from one or more of the set of remote units comprises extracting data from one or more of the time slots.

7. The method of claim 6 further comprising:

associating the data with a remote unit based on a portion of the extracted data.

8. The method of claim 1, wherein the instructions specifying a procedure to be used by the remote units to select a time slot comprise one of:

instructions to select a time slot based on selected digits of the serial number of the remote unit, instructions to select a time slot based on a pseudo-random number, and instructions to select a time slot based on the geo-location of the remote unit.

9. The method of claim 1 further comprising, polling one or more remote units directly to request polling data.

10. The method of claim 9 wherein the polling data comprises a confirmation of the existence that a functioning transmission path to the remote unit.

11. The method of claim 1 wherein the data is received on a single radio frequency channel.

12. The method of claim 11 wherein the transmitting instructions are broadcast on the single radio frequency channel.

13. The method of claim 1 wherein the data transmitted from the remote unit comprises a request to transmit a long message, wherein the long message comprises a message that takes longer to transmit than a duration of the time slot.

14. The method of claim 13 further comprising:

in response to receiving the data transmitted from the remote unit, transmitting a polling request directly to the remote unit to request the long message;

receiving the long message; and

transmitting an acknowledgement to the remote unit that the long message was received.

15. A method of transmitting data from a remote unit to a base, the method comprising:

receiving, at a remote unit, transmitting instructions from the base, the transmitting instructions comprising an Asynchronous Ubiquitous Protocol and selection instructions, the selection instructions specifying a procedure to be used by the remote unit for selecting a time slot from the Asynchronous Ubiquitous Protocol, the Asynchronous Ubiquitous Protocol comprising a schedule of a set of time slots each defined by a start time and end time pair, the start time and end time pairs defining a set of non-overlapping time slots within which data may be transmitted, wherein the plurality of time slots of the schedule are unallocated time slots eligible to be selected by remote unit;

selecting a time slot from the Asynchronous Ubiquitous Protocol within which to transmit remote unit data, the selection based on the selection instructions for selecting the time slot; and

transmitting the data to the base in accordance with the selected time slot, the data indicating an emergency event or occurrence.

16. The method of claim 15 further comprising receiving an acknowledgment message from the base.

17. The method of claim 15, further comprising transmitting the data to a hop unit selected from an ordered list of hop units stored at the remote unit, the ordered list of hop units comprising a list of units within transmission range of the remote unit.

18. The method of claim 17, further comprising monitoring the data transmitted from of the selected hop unit.

19. A communication network for reducing signal collision when transmitting data from one or more remote units out of a set of remote units, the network comprising:

a set of one or more remote units, each remote unit arranged to transmit data;

a base for communicating with the set of one or more remote units and for managing the communication network, the base associated with a database and with a processor, the processor configured to;

define an Asynchronous Ubiquitous Protocol, the Asynchronous Ubiquitous Protocol comprising a schedule of plurality of time slots, each time slot defined by a distinct start time and end time pair, the start time and end time pairs defining a set of non-overlapping time slots within which data may be transmitted, wherein the plurality of time slots of the schedule are unallocated time slots eligible to be selected by remote units;

broadcast transmitting instructions the set of remote units, the transmitting instructions comprising the Asynchronous Ubiquitous Protocol and selection instructions, the selection instructions specifying a procedure to be used by the remote unit for selecting a time slot from the Asynchronous Ubiquitous Protocol to use for data transmission; and

receive data transmitted from one of the remote units in the set of one or more remote units in accordance with the transmitting instructions, the data indicating an emergency event or occurrence.
