A device initiates voice communication sessions with a media resource function processor (MRFP) of a network, where each voice communication session communicates audio data via one or more network devices of the network. For each voice communication session, the device sends first audio data to the MRFP and receives second audio data from the MRFP via the voice communication session, processes the first audio data and second audio data to determine one or more characteristics of the second audio data, and generates a record concerning the voice communication session based on the one or more characteristics of the second audio data. The device generates a report based on a respective record of each voice communication session, processes the report using an artificial intelligence technique to identify an issue concerning at least one network device, and performs, based on identifying the issue, an action concerning the at least one network device.

Various examples are provided related to automated security analysis of baseband firmware. In one example, a system includes a wireless front end and processing circuitry communicatively coupled to the wireless front end and a target device. The processing circuitry can generate mutated packets based upon a device state of the target device; provide the mutated packets for transmission to the target device; receive feedback information from the target device in response to reception of the mutated packets; and identify a firmware flaw associated with the target device in response to the feedback information. In another example, a method includes generating mutated packets based upon a device state of a target device; transmitting the mutated packets to the target device; receiving feedback information from the target device in response to reception of the mutated packets; and identifying a firmware flaw associated with the target device using the feedback information.

A method and a test device for testing the CSI Type 2 channel estimation capability of a DUT are provided. The method includes: a) stimulating certain variance of PMI feedback values from the DUT, especially those belonging to the finer grained Type 2 CSI, b) a statistical collection of one or more PMI reports received through CSI reporting from the DUT during the test execution, c) an identification of Type 1/Type 2 PMI feedback type based on the CSI reports received from the DUT, and d) applying a pass criterion: a minimum threshold of Type 2 specific feedback reports must have been received.

One or more computing devices, systems, and/or methods are provided. In an example, a method includes instantiating a first user equipment (UE) module on a first computing device and instantiating a second UE module on a second computing device connected to the first computing device by a wired network. A first base station (BS) module associated with the first UE module is instantiated on a third computing device coupled to the wired network and a second BS module associated with the second UE module is instantiated on a fourth computing device coupled to the wired network. A first resource allocation map is sent from the first BS module to the second BS module. An interference metric is generated based on the first resource allocation map. A data transmission between the second UE module and the second BS module is modulated based on the interference metric.

A simulated Public Warning System (PWS) message is defined for efficient PWS testing. The simulated PWS message mimics a conventional PWS message, but indicates that it is not to be propagated across an air interface to UEs. However, the simulated PWS message is otherwise propagated through the network as a PWS message. This allows for testing the generation and propagation of PWS messages, without wasting valuable air interface and battery resources. In some embodiments, network nodes may initiate testing by requesting a simulated PWS message. An Access and Mobility management Function (AMF) node in a wireless communication network collects and reports network status to a PWS entity. The AMF node ascertains the functionality of network functions, nodes, and interfaces to which it is connected, independently from receiving reports of such functionality, and an indication of any detected fault or failure is sent to the PWS entity.

Devices and methods for testing altimeters are provided. A radio-frequency (RF) signal may be received from an altimeter and passed through an RF delay module to delay the RF signal.

The system tests the accuracy of the altimeter based on the combined RF signal delay and optical signal delay.
