Method for billing local communication services provided by an interexchange communication network

摘要

A method is provided to distinguish local exchange communication services provided by an interexchange carrier from other services offered by the interexchange carrier. The local exchange service typically is provided to a customer with whom the interexchange carrier provides a direct connection. For each call, a terminating switch receives a code identifying a type of service assigned to the call. The code may contain a local service identifier associated with a call that identifies the call is identifying a type of service assigned to the call. The switch determines whether the call is a POTS call and whether the code includes the local service identifier. If both conditions are met, the terminating switch generates the billing record provided the customer is a subscriber to the local service offered by the carrier.
