Thermally compensated waveguides are disclosed herein. According to one aspect, the present disclosure proposes new ways to combine negative TOC (NTOC) material layers within the waveguides. NTOC materials can be implemented in one or more of a cladding layer, a core rib / channel waveguide, a horizontally segmented waveguide, a vertically segmented waveguide, a sub-wavelength grating structure, and / or in various other waveguide structure implementations including arbitrary core or cladding shapes. The integration of NTOC materials improves the temperature dependence of the waveguide spectrum. The need for fast and efficient optical-based technologies is increasing as Internet data traffic growth rate is overtaking voice traffic, pushing the need for optical communications. The new waveguide structures can be integrated into waveguides, individual devices, integrated devices like arrayed waveguide grating devices, and photonic integration circuits (PICs), decreasing temperature dependence of such devices and circuits.

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.

Currently, spatial reuse (SR) is a feature used indiscriminately for / across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.

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.

In some implementations, a network device may receive a key performance indicator (KPI) metric associated with a media resource function, wherein the media resource function is associated with a virtualized telephone application service. The network device may compare the KPI metric to a threshold. The network device may generate an internal event based on the KPI metric satisfying the threshold. The network device may correlate the internal event and an external event, wherein the external event is based on external system formulated data, and correlation results include an indication of non-matching data or matched data between the internal event and the external event. The network device may identify a blocked voice traffic flow based on the correlation results. The network device may transmit a notification that indicates the blocked voice traffic flow, wherein the notification includes a recommendation to resolve the blocked voice traffic flow.

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.

The application discloses a method and system for optimizing resource occupation of AI voice notification of work number, and the method comprises the following steps: a calling party A writes the binding relationship between AXB into a work number server database through a voice notification server of a call center, and writes whether it is an AI voice notification at the same time; if it is an AI voice notification, the color ring capability of the AI voice notification initiating call is shielded by modifying SIP signaling of the call, so that the color ring of the called party is prevented from being triggered, and signaling and voice flow are saved; and when the called party B refuses, the call is quickly ended through 183 signaling conversion instead of waiting for timeout. The application optimizes two invalid occupation scenes for the AI voice notification of the work number, and a large amount of resources can be saved.
