The disclosure relates to a baseband processing method, comprising: receiving a downlink (DL) baseband (BB) signal in a transmission time interval (TTI), wherein the DL BB signal comprises a time-frequency resource comprising a control section and a data section; decoding at least part of the control section to detect a DL grant information; if the DL grant information is detected, determine a number of granted data resource blocks from the DL grant information; and adjust at least one of a clock rate and supply voltage of the baseband processing based on the number of granted resource blocks.

A method of providing a recent call list of calls recently received or initiated by a telecommunications device where information on recent services which are services recently handled by or using the telecommunications device other than calls are incorporated as entries in a recent call list of the telecommunications device. Each entry can be formed by a data structure being composed of a plurality of data fields. Each data field can include a data value. An entry representing a recent service other than a call in the recent call list can include a service code identifying a recent service as a data value. A device, system, and apparatus can be configured to utilize or execute the method.

An incoming communication processing system and method is disclosed for providing communication and data services to residents of a controlled facility. Specifically, the incoming communication processing system allows outside parties to initiate communications to residents of a controlled facility. The incoming communication processing system may work in conjunction with or separately from an outgoing communication processing system. Many restrictions and safeguards may be implemented within the incoming communication system in order to prevent improper use.

An embodiment of the system for publishing events of a telephony application to a client includes a call router that generates events from the telephony application and an event router that manages the publication of events generated by the call router and that manages the subscription to events by clients. The system can be used with a telephony application that interfaces with a telephony device and an application server

This disclosure falls into the field of voice communication systems, more specifically it is related to the field of voice quality estimation in a packet based voice communication system. In particular the disclosure provides a method and device for 5 reducing a prediction error of the voice quality estimation by considering the content of lost packets. Furthermore, this disclosure provides a method and device which uses a voice quality estimating algorithm to calculate the voice quality estimate based on an input which is switchable between a first and a second input mode.

A server can receive a plurality of records at a databases such that each record is associated with a phone call and includes at least one request generated based on a transcript of the phone call. The server can generate a training dataset based on the plurality of records. The server can further train a binary classification model using the training dataset. Next, the server can receive a live transcript of a phone call in progress. The server can generate at least one live request based on the live transcript using a natural language processing module of the server. The server can provide the at least one live request to the binary classification model as input to generate a prediction. Lastly, the server can transmit the prediction to an entity receiving the phone call in progress. The prediction can cause a transfer of the call to a chatbot.

Certain embodiments of the invention generally relate to lawful interception of communications for IP Multimedia System-based (IMS-based) voice over IP (VoIP). For example, some embodiments relate to interception of communications including interception for encrypted, transcoded media. A method may include identifying a network node that provides call content interception. The method may also include determining a codec type used at a location of the call content interception at the network node. The method may further include sending a matched codec of the codec type used at the location of the call content interception at the network node to a delivery function in the communications network.

A method for managing an incoming call in a communication terminal is described, the incoming call having an associated call identifier. The method can comprise checking the routing of an outgoing call to the call identifier associated with the incoming call, and classifying the incoming call on the basis of the result of the checking of the routing, the incoming call being classified as a malicious incoming call if the checking of the routing reveals that the outgoing call is not able to be routed. The method can be used, for example, to detect malicious calls or spam.

A system is provided for thwarting the undesired incoming calls and eliminating the impact of robocalls, tollfree pumping, political spam, data collection bots, and other phone fraud forms. The system has a spam detection unit with a plurality of spam type modules and each spam type module is configured to detect a different type of spam.

Aspects of the invention determining a threat score of a call traversing a telecommunications network by leveraging the signaling used to originate, propagate and terminate the call. Outer-edge data utilized to originate the call may be analyzed against historical, or third party real-time data to determine the propensity of calls originating from those facilities to be categorized as a threat. Storing the outer edge data before the call is sent over the communications network permits such data to be preserved and not subjected to manipulations during traversal of the communications network. This allows identification of threat attempts based on the outer edge data from origination facilities, thereby allowing isolation of a compromised network facility that may or may not be known to be compromised by its respective network owner. Other aspects utilize inner edge data from an intermediate node of the communications network which may be analyzed against other inner edge data from other intermediate nodes and/or outer edge data.
