1. A method, comprising: at a service design system, receiving first service plan elements of a first service plan for using a first network service; generating a first notification policy based on the first service plan elements, the first notification policy defining (1) a first notification trigger event based on a state of use by a remote user communications device of the first network service and (2) a first notification message for notifying an entity responsible for managing an aspect of the state of use of the first network service for a device group, the device group comprising a subset of one or more devices less than all devices capable of using the first network service, the device group including the remote user communications device; associating the remote user communications device with the first service plan or with the device group; generating, based on the first notification policy, a device instruction for assisting in providing notification on the state of use by the remote user communications device of the first network service when the first notification trigger event occurs; and providing the device instruction to a policy implementation agent on the remote user communications device, the policy implementation agent configured to assist in implementing the first notification policy for the remote user communications device using the device instruction.
