Abstract: A method at a network element for monitoring user plane traffic for a user equipment, the method including configuring a set of characteristics and a range of values for each of the set of characteristics for user plane traffic between the user equipment and the network element; monitoring user plane traffic for the user equipment at the network element, the monitoring determining whether at least one characteristic of the user plane traffic falls outside of the configured range of a values, resulting in a characteristic violation; and if the at least one characteristic of the user plane traffic falls outside the configured range of a values, performing an action resulting from the characteristic violation.

Abstract: An example network device includes a processor configured to execute an Open Mobile Alliance (OMA) Device Management (DM) server, the OMA DM server to perform operations of: participating in mutual authentication with a second OMA DM server; sending a notification to the second OMA DM server for notifying the second OMA DM server to proceed with a delegation process; and sending, to a DM client, information for modifying an access control list (ACL).
