The present invention relates to a method for predicting a performance indicator for a service in a network. The method is performed by a network node of the network, and the method comprises obtaining measurement data of a metric affecting a service communicating via a radio access network, RAN, node, wherein the metric is independent of the service communicating via the RAN node, inputting the obtained measurement data into a prediction model for performance of the service communicating via the RAN node, wherein the prediction model has been trained with measurement data from the RAN node and measurement data from an end node, and predicting the performance indicator for performance of the service in the network. A network node, a computer program and a computer program product are also presented.

Prose relay resource optimization

A method performed in a communication network, in which the method comprises obtaining a prediction of future available bandwidth of a radio carrier for a service application in a radio device connected to the network. The method also comprises receiving information about a status of an application buffer of the service application. The method also comprises, based on the obtained prediction and on the received buffer information, preparing a recommendation to the service application for when to fill up an application buffer of the service application. The method also comprises initiating sending of a recommendation message comprising the prepared recommendation to the radio device.

A node () of a cellular network controls sending of first uplink grants to a communication device (). The first uplink grants indicate first uplink radio resources allocated to the communication device () and are sent in response to receiving scheduling requests from the communication device (). Further, the node () controls sending of second uplink grants to the communication device (). The second uplink grants indicate second uplink radio resources allocated to the communication device () and are sent according to a configured periodicity. Depending on a periodicity of opportunities for transmission of the scheduling requests by the communication device () and the configured periodicity of sending the second uplink grants, the node () controls an alignment of the sending of the second uplink grants with respect to the opportunities for transmission of the scheduling requests.

A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.

A pre-scheduling grant transmission method performed by a network node includes issuing a first sequence of pre-scheduling grants to provide a UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting data relating to at least transmitted uplink traffic initiated by the first pre-scheduling grants to obtain a data set providing a statistical description of the traffic flow during the time period covered by the first sequence of pre-scheduling grants, predicting from the obtained data set the time when the next data packet arrives to the send buffer of the UE, and transmitting at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time, thereby providing the UE with timely resources for transmitting the data packet shortly after the packet has arrived at the UE send buffer.

Method and network node for pre-scheduling grant transmission

A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.
