This invention relates to an efficient method for identifying encrypted voice traffic, comprising: obtaining a temporal feature sequence based on the transmission direction and length characteristics of each encrypted voice traffic data packet in an encrypted voice data stream, wherein the encrypted voice stream sequence includes encrypted voice traffic data packets; mapping the temporal feature sequence from the temporal space to the frequency domain space using a frequency domain mapping method to obtain a frequency domain feature sequence; reconstructing the frequency domain feature sequence using a stacked autoencoder to obtain encoded reconstructed features; and inputting the encoded reconstructed features into a convolutional neural network model to obtain a classification result. This invention ensures the real-time performance and effectiveness of encrypted traffic classification, effectively improves the accuracy of network traffic classification, and enhances the flexibility and generalization ability of network traffic identification.

A method of voice call handling and related apparatuses are provided. The method by a user equipment (UE) includes initiating a mobile originated (MO) voice call when the UE is registered to a first RAN applied with a first RAT; performing either handover or voice call redirection from the first RAN to a second RAN applied with a second RAT, wherein an attempt of the UE at establishing a PDU session with the first RAN for IMS voice traffic for the MO voice call is rejected by a core network if the first RAN does not support IMS voice service; and establishing the PDU session with the second RAN for the IMS voice traffic for the MO voice call on the second RAT to start voice call. This method can reduce voice call setup delay.

A system and method for processing Voice over Internet Protocol (VoIP) traffic flows, particularly encrypted VoIP traffic flows, on a computer network. The method includes collecting traffic flow data for IP sessions, collecting parameters associated with the IP sessions, determining whether the IP sessions are VoIP sessions, correlating IP sessions having similar parameters with the collected parameters, and creating at least one Internet Protocol Detail Record (IPDR) or Call Detail Record (CDR) based on the correlated IP sessions. The system includes a collection module configured to collect traffic flow data, an analysis module configured to determine the parameters and determine whether the IP sessions are VoIP sessions, and a correlation module configured to correlate IP sessions having similar parameters and create at least one Internet Protocol Detail Record (IPDR) or Call Detail Record (CDR) based on the correlated IP sessions.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more control messages that indicate both an uplink semi-persistent scheduling (SPS) configuration for voice traffic for the UE and a downlink SPS configuration for the voice traffic for the UE. The UE may receive, in accordance with the downlink SPS configuration, one or more downlink voice packets for the UE via first downlink resources of a plurality of downlink resources indicated by the downlink SPS configuration indicated by the one or more control messages. The UE may transmit, in accordance with the uplink SPS configuration, one or more uplink voice packets for the UE via first uplink resources of a plurality of uplink resources indicated by the uplink SPS configuration indicated by the one or more control messages.

The invention relates to voice service quality prediction in a network. The present disclosure proposes a network device for estimating and / or predicting the quality of voice traffic of a UE, where the network device is associated with a serving cell of the UE, and the network device is configured to: receive one or more measurement reports from the UE, where each measurement report comprises one or more wireless measurement results collected by the UE during voice traffic in the serving cell; a first probability of the UE is obtained based on the one or more measurement reports, where the first probability indicates a probability of occurrence of a low quality traffic event in the serving cell. The present disclosure also proposes a UE for assisting quality estimation and / or prediction of voice services.

The embodiment of the invention relates to a voice service processing method and device and a medium, and the method comprises the steps: determining a voice service estimated value of a next round of period based on the voice traffic of a target cell in a current period; acquiring a spectrum efficiency value of each physical resource block PRB of the target cell for processing the voice service in the current period; and on the basis of the spectrum efficiency value for bearing the voice service in the current period, determining a reserved sub-band of the target cell for bearing the estimated value of the voice service in the next round of period, the reserved sub-band comprising at least one PRB. In the technical scheme, the reserved sub-band of the next period is dynamically determined by periodically combining the voice service estimated value and the spectrum efficiency value of each physical resource block PRB, and the service quality of the voice service is improved.
