Abstract

Methods and apparatus for supporting customer charging in 5G networks are provided. Monitoring functions are instantiated at selected network locations for tracking access to network services. The monitoring functions provide charging information for use in customer billing. A customer can enter a service level agreement with a particular customized method of charging for service usage, and the monitoring functions can be customized to provide charging information according to the service level agreement. Charging can vary based on factors such as time of day, network congestion, service traffic characteristics, and geographic location.
