Abstract

A method of controlling a radio-frequency (RF) transaction region comprises: determining a value of a characteristic associated with an ability of roadside equipment, associated with an RF transaction, to obtain information from a user equipment (UE) in the RF transaction region; determining, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and conveying the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.

First claim

The invention claimed is:

1. A method of controlling a radio-frequency (RF) transaction region, the method comprising:
determining a value of a characteristic associated with an ability of roadside equipment, associated with an RF transaction, to obtain information from a user equipment (UE) in the RF transaction region, the characteristic comprising a predicted loss rate of the RF transaction region, based on a loss rate of the RF transaction region corresponding to at least one first day prior to a present day, the loss rate being a first quantity of UEs determined, from measurements, to enter the RF transaction region during a time interval that fail to trigger a transaction relative to a second quantity of a total number of UEs determined to enter the RF transaction region during the time interval, and the predicted loss rate being a predicted rate at which UEs entering the RF transaction region fail to trigger a transaction;
determining, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and
conveying the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.

2. The method of claim 1 , wherein the characteristic is comprises at least one of a measured RF environment of the RF transaction region, a measured transaction loss rate of the RF transaction region, a congestion schedule of the RF transaction region, or a predicted RF environment of the RF transaction region, based on an RF environment of the transaction region corresponding to at least one second day prior to the present day.

3. The method of claim 1 , wherein the parameter comprises:
(a) a perimeter of the RF transaction region; or
(b) a minimum number of transaction messages to be sent by the UE while in the RF transaction region; or
(c) a maximum number of the transaction messages to be sent by the UE while in the RF transaction region; or
(d) a rate of the transaction messages to be sent by the UE while in the RF transaction region; or
(e) a transmission power to be used by the UE to transmit the transaction messages while in the RF transaction region; or
(f) a combination of two or more of (a)-(e).

4. The method of claim 3 , wherein the parameter comprises the rate of the transaction messages to be sent by the UE while in the RF transaction region, and wherein the rate of the transaction messages to be sent by the UE while in the RF transaction region is a function of speed of the UE while in the RF transaction region.

5. The method of claim 3 , wherein the parameter comprises the rate of the transaction messages to be sent by the UE while in the RF transaction region, and wherein the rate of the transaction messages to be sent by the UE while in the RF transaction region is a portion of position messages in which the UE is to include the transaction messages.

6. The method of claim 1 , wherein conveying the value of the parameter to the UE comprises conveying the value of the parameter to the UE from the roadside equipment or from a back-end device.

7. An apparatus configured to affect a radio-frequency (RF) transaction region, the apparatus comprising:
a transmitter; and
a processor communicatively coupled to the transmitter and configured to:
determine a value of a characteristic associated with an ability of roadside equipment associated with an RF transaction to obtain information from a user equipment (UE) in the RF transaction region, the characteristic comprising a predicted loss rate of the RF transaction region, based on a loss rate of the RF transaction region corresponding to at least one first day prior to a present day, the loss rate being a first quantity of UEs determined, from measurements, to enter the RF transaction region during a time interval that fail to trigger a transaction relative to a second quantity of a total number of UEs determined to enter the RF transaction region during the time interval, and the predicted loss rate being a predicted rate at which UEs entering the RF transaction region fail to trigger a transaction;
determine, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and
send the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.

8. The apparatus of claim 7 , wherein the characteristic is comprises at least one of a measured RF environment of the RF transaction region, a measured transaction loss rate of the RF transaction region, or a congestion schedule of the RF transaction region, or a predicted RF environment of the RF transaction region, based on an RF environment of the transaction region corresponding to at least one second day prior to the present day.

9. The apparatus of claim 7 , wherein the parameter comprises:
(a) a perimeter of the RF transaction region; or
(b) a minimum number of transaction messages to be sent by the UE while in the RF transaction region; or
(c) a maximum number of the transaction messages to be sent by the UE while in the RF transaction region; or
(d) a rate of the transaction messages to be sent by the UE while in the RF transaction region; or
(e) a transmission power to be used by the UE to transmit the transaction messages while in the RF transaction region; or
(f) a combination of two or more of (a)-(e).

10. The apparatus of claim 9 , wherein the parameter comprises the rate of the transaction messages to be sent by the UE while in the RF transaction region, and wherein the rate of the transaction messages to be sent by the UE while in the RF transaction region is a function of speed of the UE while in the RF transaction region.

11. The apparatus of claim 9 , wherein the parameter comprises the rate of the transaction messages to be sent by the UE while in the RF transaction region, wherein the rate of the transaction messages to be sent by the UE while in the RF transaction region is a portion of position messages in which the UE is to include the transaction messages.

12. The apparatus of claim 7 , wherein the processor is configured to cause the transmitter to send the value of the parameter to the UE wirelessly.

13. An apparatus configured to affect a radio-frequency (RF) transaction region, the apparatus comprising:
means for determining a value of a characteristic associated with an ability of roadside equipment associated with an RF transaction to obtain information from a user equipment (UE) in the RF transaction region, the characteristic comprising a predicted loss rate of the RF transaction region, based on a loss rate of the RF transaction region corresponding to at least one first day prior to a present day, the loss rate being a first quantity of UEs determined, from measurements, to enter the RF transaction region during a time interval that fail to trigger a transaction relative to a second quantity of a total number of UEs determined to enter the RF transaction region during the time interval, and the predicted loss rate being a predicted rate at which UEs entering the RF transaction region fail to trigger a transaction;
means for determining, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and
means for conveying the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.
