Abstract: Methods, devices, systems, techniques, and computer program products are provided to secure timing synchronization to network nodes connected over an inherently insecure best effort public network with mechanisms to improve accuracy of timing protocols such as a statistically estimated edge timestamp offset encoded into the timing message to account for network jitter and processing latency variances incurred due to the security packet processing and encryption; to ensure slave network nodes shall only accept timing messages from trusted timing sources; to establish a secure tunnel with a trusted timing source for exchange of timing packets; to provide authentication and security for timing packets over the insecure public network; and to enhance message anonymity with variable payload padding.

Abstract: Various communication systems may benefit from notifications of network information. For example, cellular optimization may be accomplished by selective use of a data technique by applications on network devices, which may further benefit from notifications that may reduce the need for external data requests, used in coordination with application observations of current network conditions. According to certain embodiments, a method can include monitoring network service viability for a user or application. The method can also include sending a push message to a user equipment when network service viability is detected for the user or the application. The push message can indicate at least one threshold associated with network service viability.

Abstract: Certain example embodiments may generally relate to multi-security levels/traffic management across multiple network function instantiations, including virtualized network function instantiations. A method may include configuring a first instantiation of a first network function to provide a first type of security. The method may also include configuring a second instantiation of the first network function to provide a second type of security that is different than the first type of security. The method may further include allocating at least some of the subscriber traffic to the first instantiation.
