  • Method and apparatus for subscription adaptation
    Patent number: 10284729
    Abstract: A subscription adaptation engine computes a network utilization metric for a plurality of resource bins, each resource bin representing the network utilization at a network location within a time slot. A subscriber utilization metric is computed for activities by a subscriber within the resource bins and a subscriber predictability metric is computed for the subscriber based on the subscriber utilization metric and network utilization metric. Subscriber profiling is performed for the subscriber based on the subscriber utilization metrics and subscriber predictability metric and a subscription profile for the subscriber is adapted, thereby enabling service charging based on the adapted subscription profile. The amount of real-time or near real-time signaling needed to show a different price for each location and/or time of a user may thereby be reduced.
