A troubleshooting method based on network function virtualization is provided, where the troubleshooting method may include: obtaining, by a first function management entity, fault information of a function entity; triggering, by the first function management entity, fault correlation processing according to the fault information, and formulating a troubleshooting policy according to a result of the fault correlation processing; and if the troubleshooting policy is formulated when troubleshooting time arrives, processing, by the first function management entity, a fault according to the troubleshooting policy; or if the troubleshooting policy is not formulated, processing, by the first function management entity, a fault according to a preset troubleshooting policy, where the preset troubleshooting policy is a policy formulated for a fault generated due to a reason of the function entity, so as to ensure that a service is not interrupted in a troubleshooting process, so that user experience is improved.

Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. A time adjustment may be determined and applied to uplink transmission timing of a cell group. A transmission timing difference between a first cell group and a second cell group may be determined. If the transmission timing difference exceeding a threshold, one or more devices may stop transmitting uplink signals via one or more secondary cells and/or may stop applying the timing adjustment for a cell group.

Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.

Next generation network architectures enable instantiation of network slices in which traffic may be transported via one or more virtual networks overlaying the physical network infrastructure. To enable a slice management system to be able to obtain information on virtual networks of instantiated network slices, such as utilization data indicative of at least one of: a bandwidth capacity, computing capacity and storage capacity of one or more physical links via which traffic of the virtual networks is routed, an interfacing system is provided. The interfacing system may establish an interface between the slice management system operating in the domain of network slices and the network management system operating in the domain of physical network equipment, and thereby enable the slice management system to take into account such utilization data in its slice management operation.

An apparatus is described. The apparatus includes electronic circuitry to support multiple flows within a network. The electronic circuitry to determine respective telemetry information for the multiple flows and inject an alarm message into a particular one of the multiple flows upon an alarm condition being reached for the particular one flow. The alarm message includes a multi-bit error code that describes the alarm condition. The multi-bit error code is one of multiple, possible multi-bit error codes.

A wireless communication network manages a wireless access node. The wireless access node wirelessly exchanges user data with wireless User Equipment (UEs) and exchanges the user data with one or more network elements. The wireless access node generates status indicators that characterize wireless access node operation during the user data exchanges. An Element Management System (EMS) determines EMS load based on EMS operation and transfers load data that indicates the EMS load for delivery to the wireless access node. The wireless access node receives the load data transferred by the EMS. The wireless access node identifies individual priorities for individual ones of the status indicators. The wireless access node determines individual reporting times for the individual ones of the status indicators based on the load data and the individual priorities. The wireless access node transfers the individual ones of the status indicators to the EMS per the individual reporting times.

Systems, methods, and computer-readable media for receiving an indication of an equivalence failure, the equivalence failure corresponding to one or more models of network intents. The indication of the equivalence failure is analyzed and one or more constituent intents that caused the equivalence failure are identified, wherein the one or more constituent intents are associated with a model of the one or more models of network intents. The granularity of the equivalence failure and the identified one or more constituent intents is determined, and an event for external consumption is generated, the event based at least in part on the equivalence failure, the granularity of the equivalence failure, and the identified one or more constituent intents.
