The subject matter disclosed herein relates to a method for checking toll transactions, produced from position notifications of a mobile phone connected via a mobile network to a transaction server, with the aid of a network of distributed toll beacons, which can communicate via short-range radio with on-board units of passing vehicles and are connected to the transaction server. To this end, a interoperable multi-functional OBU is created that is formed from a GNSS- and NFC-enabled mobile phone on the one hand and an NFC- and DSRC-enabled OBU on the other hand, which exchange data concerning a session identifier (SID) via their common NFC interface, which session identifier forms a link between the infrastructureless and the infrastructure-bound billing functions of the multi-functional OBU. The disclosed subject matter also relates to a toll beacon and a transaction server for same.

Method for transmitting messages in ad hoc networks
A method provides for wireless transmission and reception of messages in an asynchronous ad hoc network having multiple network nodes, of which at least a first network node periodically transmits messages with a predefined period length. A second network node carries out: Defining two consecutive time intervals, each having the length of one period and a first time interval being past and a second time interval being future; subdividing the time intervals into two time slots each; calculating an occupancy for each time slot of the first time interval based on the number of messages of other network node(s) received in this time slot; identifying the time slot having the lowest occupancy; and transmitting a message in a time slot of the second time interval that corresponds to the identified time slot. The exact transmission point is defined on the basis of the time stamp derived from the synchronized TSF.

A system and method for conducting dynamic RF-link margin tests in an electronic toll collection for non-stationary vehicles travelling up to highway speed. The system maintains a list of candidate transponders and, during the course of a normal toll collection, if a transponder is on the list then the system schedules a margin test for a later handshake in the capture zone. At a location at or near the peak margin test the system conducts a margin test during one or more of the reader-transponder handshakes. The attenuation may be dynamically controlled by the system using a variable attenuator in the RF path from the reader RF module to the antenna. Distributing the margin measurement over multiple passes of a vehicle through the capture zone provides for a highway speed method of measuring link margin.
