A device may receive, from a network device, a credit control request to allocate a quota to a subscriber device. The quota may relate to access, by the subscriber device, to network resources provided by a network provider. The device may determine a subscriber value based on historical usage of network resources by the subscriber device, identify a group value based on historical usage of network resources by a group of subscriber devices with which the subscriber device is associated, and determine a particular quota to allocate to the subscriber device based on a baseline quota, the subscriber value, and a group value. The device may perform one or more actions to cause the particular quota to be allocated to the subscriber device based on determining the particular quota.
