A wireless device, network node and network management node are disclosed. The wireless device, network node and management node may cooperate to facilitate monitoring of the wireless device and detection of an incident involving a user of the wireless device. The wireless device is operable to connect to a network and comprises processing circuitry configured to cause the wireless device to enter an enhanced monitoring mode, receive, from a network node, configuration information specifying a measuring configuration for measuring signal strength, and measure signal strength in accordance with the received configuration information.

Enhanced monitoring and incident detection in a network

A method of operating a protection node for protecting a pattern classification node from malicious requests may be provided. The protection node may receive, from a user node, a request containing an original pattern to be classified by a machine learning algorithm performed by the pattern classification node. The protection node may add noise to the original pattern to generate a noisy pattern. The protection node may obtain a first classification of the noisy pattern based on processing of the noisy pattern by a first clone of the machine learning algorithm at the protection node; obtain a second classification of the original pattern based forwarding the request for processing of the original pattern by the machine learning algorithm performed at the pattern classification node; and compare the first and second classifications to determine whether the first and second classifications satisfy a defined similarity rule. The protection node may use the comparison to manage the request from the user node.

Methods for protecting pattern classification node from malicious requests and related networks and nodes

A first communications device () for detecting disturbing sound () is provided, operative to acquire a first representation of sound audible in a surrounding () of the first communications device, acquire, from second communications devices (-) which are spatially separated from the first communications device, second representations of sounds audible in the surroundings () of the second communications devices, and determine at least one second representation of sound which represents the same sound originating from the same source of sound. The first communications device is further operative to perform one or both of: i) if a sound level of a second representation of sound representing the same sound from the same source as the first representation of sound exceeds a first sound level threshold, and if the first communications device is proximate to the source of the sound, one or more of: trigger a notification to a user of the first communications device, reduce a volume of media played-out by the first communications device, and stop play-out of media by the first communications device, and ii) if a sound level of the first representation of sound exceeds a first sound level threshold, send a disturbance notification to the second communications device which is proximate to the source of the sound.

Detecting disturbing sound

Methods and systems automatically protect radio network equipment in extreme weather conditions such as sand-storms or snow-storms. A pair of phase-shift material grids having different orientations is installed at an air intake of the radio network equipment. One of the grids is powered to open or close the air intake according to a current amount of air-carried particles entering the radio network equipment and a temperature inside the radio network equipment. The current amount of air-carried particles entering the radio network equipment may be detected by a piezoelectric sensor.

A method and radio base station for handling a power disturbance caused by a radio unit of the radio base station. The method comprises: obtaining scheduling information of data traffic associated with the RU; comparing the power disturbance with one or more first thresholds, wherein the power disturbance is caused by the RU adapted to handle the data traffic according to the scheduling information; and adjusting a switching frequency of a direct current to direct current, DC/DC, converter based on the comparison, wherein the DC/DC converter is comprised in the RU to power the RU.

A relay-proxy device has first and second interfaces allowing connection to a first node and a second node respectively, wherein the relay-proxy device is configured with at least one key, and the relay-proxy device is operable to: receive a traffic flow in an encrypted transport protocol on the first interface; decrypt a first part of the traffic flow with said key, wherein a second part of the traffic flow cannot be decrypted with said key; perform a management function based on a content of the decrypted first part of the traffic flow; and forward at least the second part of the encrypted traffic flow to the second interface.

Transport relay in communications network

A server (), a client device () and methods therein, for handling cached content resources. When the client device () sends a download request () in a downloading session, the server () identifies () at least one content resource deemed to be potentially needed later in the downloading session. The server () then sends a cache map to the client device () in a response to the download request. The cache map comprises a pre-fetch indication indicating that the identified at least one content resource should be pre-fetched by the client device () from a cache () containing the identified at least one content resource. Thereby, the client device is able to pre-fetch () the content resources before the performance of communication may become reduced so that communication with the cache () is difficult or even impossible, e.g. due to deteriorated radio conditions or congestion in the communication network.

Server, client device and methods therein for handling

A server (), a client device () and methods therein, for handling cached content resources. When receiving () a request from the client device () in a downloading session, the server () identifies () a set of caches () that can be accessed by the client device (). The server () then sends () a cache map to the client device () indicating that a first content resource is stored in a first cache () of the identified set of caches and a second content resource is stored in a second cache () of the identified set of caches. Thereby, the server () is able to adapt the cache map depending on which caches can be accessed by the client device (), to ensure that the client device () can retrieve the content resources in an efficient manner.
