Method for charging telecom sessions using connection IDs from stateful transport protocols like QUIC to link messages to user sessions.

Patentradars sammanfattning

This invention addresses session charging in telecommunications by leveraging connection-oriented stateful transport protocols (e.g., QUIC) to maintain session identity and enable accurate charging. The Application Function (AF) and User Equipment (UE) exchange connection IDs that serve as session identifiers, stored in either a Charging Function (CHF) or Policy Control Function (PCF). These connection IDs enable the network to correlate exchanged messages with specific sessions and generate accurate Charging Data Records (CDRs) for billing purposes.
