ISO 15638-15:2014 provides specifications for common communications and data exchange aspects of the application service vehicle location monitoring that a regulator may elect to require or support as an option, including
a) high-level definition of the service that a service provider has to provide,
NOTE The service definition describes common service elements; but does not define the detail of how such an application service is instantiated, not the acceptable value ranges of the data concepts defined.
b) means to realize the service, and
c) application data, naming content, and quality that an IVS has to deliver.
