Vehicle Data Exchange Billing via Profile-Based Access Point Routing

The patent introduces a connection unit as an intermediary component that mediates between the vehicle's data exchange system and multiple users. This connection unit contains an allocation table that automatically assigns access point names to users based on their identifiers, thereby implementing user-specific charging without requiring complex manual configuration or intervention. The intermediary handles the complexity internally while presenting a simple interface to users.

The system performs preliminary actions by pre-configuring an allocation table that contains user identifiers and their corresponding access point names before actual data service usage occurs. This pre-assignment mechanism enables automatic user identification and billing classification without real-time complex processing, thereby improving ease of operation while managing system complexity through advance preparation.

The connection unit serves multiple functions simultaneously: it manages data exchange, performs user identification, selects access point names, and enables billing classification. By consolidating these functions into a single multi-functional component rather than separate systems, the patent reduces implementation costs and technical complexity while achieving user-specific charging.

The system changes parameters by using different access point names to represent different billing scenarios (e.g., free services versus charged services, different user types). This parameter-based approach allows flexible billing configuration without requiring complex hardware or software changes, thereby reducing implementation costs while maintaining ease of operation.
