A video based maintenance method, a maintenance terminal, a server, a system, and a storage medium. The method includes: receiving, by a maintenance terminal, a maintenance order sent by a server, wherein the maintenance order is generated according to a maintenance request sent by a client, and the maintenance order comprises customer information, faulty product information and fault information; and wherein the fault information comprises one or more troubleshooting points; receiving, by the maintenance terminal, a video stream sent by the client; and recording, by the maintenance terminal, troubleshooting information of the troubleshooting points, and sending the troubleshooting information to the server.

Protocol Data Unit (PDU) sessions in a communication network (10) provide logical interconnections between Data Networks (DNs) (16) and respective User Equipments (UEs) (12) that access the DNs (16) via the communication network (10), and the communication network (10) establishes one or more affiliated sessions in conjunction with each PDU session, such as an affiliated charging or policy control session. Rather than requiring the high signaling overhead associated with mass terminations of these affiliated sessions on a per session basis, the Network Functions (NFs) (32, 34, 36) contemplated herein provide for batch termination of a potentially large plurality affiliated sessions, based on the exchange of a corresponding batch termination message. Disclosed batch termination techniques include the exchange of information during session establishment, for later determination of which affiliated sessions are subject to batch termination.

A network management apparatus according to an embodiment includes: a storage device configured to store information indicating a correspondence relationship between information objects related to a logical layer, information objects related to a physical layer in a network configuration, and information objects related to a facility layer which are objects in which the information objects related to the physical layer are housed; an acquisition unit configured to acquire an information object related to an occurrence path of a failure in the logical layer of the network configuration, from the storage device; and a search unit configured to search for, among the information objects related to the facility layer stored in the storage device, an information object related to the facility layer and the physical layer associated with the information object related to the occurrence path of the failure acquired from the acquisition unit, as a candidate for a facility that causes the failure.

A method for determining a fault root cause includes obtaining first fault information, where the first fault information includes M alarms, and M is an integer greater than or equal to 1; determining, from N pieces of known fault information based on the M alarms, at least one piece of known fault information that matches the first fault information, where each of the N pieces of known fault information includes a plurality of alarms; and determining, based on a fault root cause of the at least one piece of known fault information, information related to a root cause of the first fault information. The root cause of the first fault information is determined by using the known fault information that matches the first fault information.

Embodiments of the present disclosure provide for predicted operational support data object selection and provision functionality. Predicted operational support data object(s) may be selected and provided to address particular malfunction classification(s) affecting networked device(s) on a dynamic home communications network. Some embodiments include identifying, in real-time, a device identification data set associated with a networked device set communicable with the dynamic home communications network; retrieving a device activity data set associated with the networked device set; applying a malfunction classification data model to the device activity data set to select the predicted operational support data object from the device operational support management repository; and outputting the predicted operational support data object to a client device in communication with the dynamic home communications network. The malfunction classification data model is trained based on training data, external aggregated activity data, and malfunction device history data.

Systems and methods for logical to physical link mapping in a fiber optic network are provided. In one implementation, a method includes receiving geographic data related to one or more fiber links in a fiber optic network; receiving logical links on the one or more fiber links; receiving results from one or more tests performed on the one or more fiber links; utilizing the results to determine a physical representation of the one or more fiber links; and displaying a network map of the fiber optic network with the physical representation.

A method of determining a problem with data packet transmission speed over a first communication medium coupled between a plurality of content servers and an ISP communication device. The method comprises repeatedly measuring the data packet transmission speed over the first communication medium coupled between each of the plurality of content servers and the ISP communication device, and determining there is a problem with the data packet transmission speed over the first communication medium coupled between one of the plurality of content servers and the ISP communication device when the repeatedly measured data packet transmission speeds over the first communication medium coupled between the one of the plurality of content servers and the ISP communication device is substantially different from the repeatedly measured data packet transmission speeds over the first communication medium coupled between other of the plurality of content servers and the ISP communication device.
