common information

 

All of the transactions that ultimately originate from a mobile device will include a group of "common elements".  There are a few host-originated transactions (e.g. Entity Definition Synchronization) that will not include the common elements since that data is not relevant.

The purpose of the common elements is to convey the fundamental mobile-related information about each event in a uniform way.  Namely, the common elements provide answers to the following questions:

  • When did the mobile event occur?
  • What entities are relevant to the event? (Vehicle, Trailer(s), Driver)
  • Where did the event occur?

It is important to understand these concepts about the common elements:

  • Some elements may be omitted on a particular transaction because they are not relevant or otherwise unknown.  For instance a Trailer Position Report may or may not include a Vehicle ID element depending on whether the trailer is connected or not.  A Return Text Message may or may not include a Driver element based on whether a Driver is logged in.
  • Some elements may be duplicated on a particular transaction because more than one of them is relevant.  For example, multiple Trailer IDs may be included if a Vehicle is connected to a double.  Two proximity references will be furnished; one for nearest city, and another for nearest small town.

Elements common to most transactions include:
