Techniques related to the management of communication devices using a combination of local and centralized blockchains to enable the detection of state changes that deviate from the expected behaviors are disclosed. In one example aspect, a method for detecting code injection activity in communication devices by a machine learning based platform includes determining, by a verification system, baseline information about a communication device; detecting a state change of the communication device, responsive to the state change of the communication device; appending, by the verification system, a current-state block representing the state change to a prior-state block representing a previous state of the communication device in a blockchain; and detecting whether a suspicious attack has occurred by comparing the payload of the current-state block to the baseline information.

A method for partitioning media content across different network slices in a network is comprises receiving, by a device from a server via a first network slice, a first ledger and a first partition of objects. The first ledger comprises data describing the first partition of objects and parameters for rendering the first partition of objects, and the first network slice is a first logical portion of the network associated with network elements configured to forward traffic according to a first quality of service network performance criteria. The method further comprises rendering, by a rendering application of the device, the first partition of objects based on the first ledger.

Solutions for low latency edge processing for unmanned aerial vehicle (UAV, 'drone') wireless links (e.g., air interfaces) include: receiving, by a first base station of a cellular network, from a UAV controller, over a first air interface, a first signal; routing the first signal from the first base station to the UAV, over a second air interface, without routing the first signal through a virtual private network (VPN); and controlling a flight parameter of the UAV based on at least the first signal. Further examples include: registering, by a UAV controller, with a cellular network; registering, by a UAV, with the cellular network; transmitting, by the UAV controller, to a first base station of the cellular network, over a first air interface, a first signal; and receiving, by the UAV, from the cellular network, over a second air interface, the first signal, without routing the first signal through a VPN.

Low latency edge processing for drone wireless links

An improved multiple-input multiple-output (MIMO) solution is disclosed for customer premises equipment (CPE) in which a set of wireless interfaces (e.g., cellular and WiFi), each with a plurality of antenna ports for MIMO operation, couple to an antenna switch fabric, which is then coupled to a set of antennas. In some examples, the antennas are distributed for maximum isolation and separation in order to improve MIMO channel separation, for example in an approximately spherical arrangement. The antenna switch fabric is instructed to select the optimal antennas based on signal parameter measurements, in order to improve overall performance. Selection of uplink (transmit) versus downlink (receive) antenna sets may be independent and based on different signal parameter measurements (e.g., for frequency division duplexing, FDD).

MIMO for CPE

Approaches to preventing degraded video presentation use reference video quality measurement feedback from a video decoder node that is receiving live action video streams from a video encoder across a cellular network. A reference video stream is encoded along with the live action video streams, and the video decoder node compares the decoded reference video stream with a local copy to determine video quality. The video decoder node provides video encoding parameter feedback for adjusting the encoding and/or provides cellular network feedback for adjusting a transmission parameter for data traffic through the cellular network (from the video encoder node to the video decoder node). Solutions are disclosed for implementation at the video encoder, at the video decoder, and within the cellular network. For example, different compression codecs may be specified, and bit rates, frame, rates, key frame intervals, and/or bit depth may be automatically (immediately) adjusted without requiring human intervention.

A mechanism of authenticating a communication device onto a radio access network via a private wireless gateway is described. This includes communicating with a communication device via a first wireless interface authentication information, a preferred roaming list (PRL), and an initial access value are obtained from the communication device. A first expected access value is determined based on rolling code data and a secret function. The PRL is authenticated when the first expected access value matches the initial access value. The communication device is proxied onto a radio access network via a second wireless interface. The proxying includes providing the authentication information and the PRL to a cell site attached to the radio access network.
