Dynamic permit/deny UE/realm list update and cost optimization based on network attach failure incidents

Abstract:

A method is performed by a control center that resides in a home network. Upon receiving, from access networks, attach requests from user equipments (UEs) when the UEs attempt to connect to the access networks, the control center computes a baseline attach failure rate for the attach requests. The control center initially sets a billing type for a UE of a subscriber to usage based billing. Upon receiving, from the access networks, attach requests from the UE when the UE attempts to connect to the access networks, the control center computes an individual attach failure rate for fulfilling the attach requests from the UE. The control center determines whether the individual attach failure rate for the UE exceeds the baseline attach failure rate. When the individual attach failure rate exceeds the baseline attach failure rate, the control center automatically switches the billing type for the UE to flat rate billing.
