Abstract: Techniques for handling requests from a remote device are disclosed. A server receives a first unsolicited activation request from a first device of a plurality of devices. A probabilistic hash filter, associated with a data set, is queried using a first identifier associated with the first device. In response, a first result is received from the probabilistic hash filter indicating that the first device is not ready for activation. In response to receiving the first result, a back-off indication is transmitted to the first device.

Abstract: Techniques for establishing network policy parameters for an internet of things (IoT) device. A first network message is received from the IoT device using a cellular communication network. The first network message includes a protocol configuration options (PCO) element including a network policy identifier relating to the IoT device. A packet data network gateway (PGW) in the cellular communication network determines network policy parameters relating to the IoT device and the cellular communication network, based on the policy identifier. The network policy parameters for the IoT device are established in the cellular communication network.

Abstract: Techniques for dynamic prioritization of network session are provided. A first packet belonging to a first session is received at a data plane of a network. Upon determining that the first packet is part of a first roam event, a first bloom filter bank is searched to determine a priority associated with the first session, where the priority is based at least in part on a historical latency experienced during the first roam event. A first queue of a plurality of queues is selected based on the determined priority, and the first packet is added to the first queue, where packets in the plurality of queues are transmitted to a control plane of the network based on a respective priority assigned to each of the plurality of queues.

Abstract: Techniques and mechanisms for secure management of network device configuration and audit are provided. A configuration blockchain is received by a first network device of a plurality of network devices. Additionally, the first network device analyzes the configuration blockchain to identify a plurality of configuration records associated with a second network device of the plurality of network devices. For at least one respective configuration record of the plurality of configuration records, the first network device determines a respective configuration change reflected in the at least one respective configuration record, and implements the respective configuration change on the first network device.

Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

Abstract: Techniques for improved wireless ranging are provided. A first communication from a first client device is received at a first network device. A predefined minimum distance is determined for the first access point, where the predefined minimum distance corresponds to a distance at which the vertical location of the first network device causes time of flight ranging techniques to result in inaccurate location estimations. A first distance of the first client device from the first network device is estimated. Upon determining that the first distance of the first client device is below the predefined minimum distance, ToF ranging requests from the first client device are declined.
