Service Packaging
How should subscriber policies be organized into services, if at all? Some considerations for service
packaging include the following:
• Are certain policy combinations common to multiple subscribers?
• Are shared policy combinations dependent on a particular forwarding domain?
• Is it necessary for a subscriber to move between service domains?
• Should services be defined on the device or in a remote repository? Externally defined services will
be cached locally for as long as they are activated for one or more sessions.
Billing Model
How should subscribers be billed for service usage? Billing options include the following:
• Billing by usage of time or volume
• Billing at regular intervals (traditional postpaid)
• Billing according to policies provisioned for the session
• Billing according to the time of day (tariff switching)
