devices to support massive deployments, enabling carrier networks to provide connectivity for both cellular and non-cellular IoT devices, and enabling the efficient use of spectrum for device-to-device (D2D) communications. A wide range of new and diverse use cases will need to be supported by the 3GPP ecosys- tem. This needs to be done at the same time that the industry continues to support the Introduction and Background XXXV traditional mobile broadband use cases. The new use cases are expected to come with a wide range of requirements on the network operation. For example, there will be different requirements on functionalities such as charging, policy control, security, mobility, speed, and availability. Some use cases such as mobile broadband may require application-specific charging and policy control while other use cases can efficiently be managed with simpler charging or policies. Some use cases also have significant differences in performance requirements, for example, power consumption and complexity, meaning that it will not be acceptable to simply provide applications with the superset of all requirements. In order to manage the multitude of service segments and verticals in a sustainable manner, there is a need to isolate the often intrinsically different segments from each other. For example, a scenario where a large number of consumer premises' electricity meters are mal- functioning in the network should not negatively impact the services provided to eMBB users or the healthcare and safety applications. In addition, with new verticals supported by the 3GPP community, there will also be a need for independent management and orchestra- tion (MANO) of segments, as well as providing analytics and service exposure functionality that is customized to each vertical's or segment's need. The functionality should not be restricted to providing isolation between different segments but also to allow an operator to deploy multiple instances of the same network partition.
