Abstract: A wireless communication device is configured to determine a speed at which it is moving based on timing advance values, which are provided by a base station in order to synchronize TDMA communications. The timing advance values are received at periodic intervals, and indicate by how much time the device should advance its data bursts so that they arrive at the base station within the correct TDMA timeslot. Each timing advance value can be multiplied by the length of a timeslot and by the propagation speed of radio waves to determine the distance of the device from the base station. The speed of the device can be determining by analyzing changes in this distance over time. When the device detects that it is moving at greater than a threshold speed, the device disables certain activities or functions that might be distracting to a driver of a vehicle.

Abstract: Systems and methods are described herein for determining dropped call rates (DCR) for various communications networks, such as IP Multimedia Networks (IMS), which include Voice over LTE (VoLTE) networks. For example, the systems and methods utilize data (e.g. abnormal cause codes) generated by layers of the IMS networks, such as a Session Initiation Protocol (SIP) layer of the IMS network, when determining dropped call rates for IMS networks.

Abstract: Systems and methods for managing communications among a central entity and multiple local entities in a telecommunication core network are disclosed. Localized central entities may be established across the core network based on localization patterns of telecommunication devices. The localized central entities may duplicate a portion of central entity data and provide local entities more efficient access to the data.

Abstract: Systems, methods, and computer-readable media are disclosed for managing performance of communications over a Voice over Long Term Evolution (VoLTE) network. A packet flow associated with a VoLTE call may be monitored, and an interruption in the packet flow that exceeds a threshold duration may be determined to be an abnormal termination of the VoLTE call. Information regarding the abnormal VoLTE call termination may be propagated through various network platforms to an enhanced Node B (eNB), where an abnormal VoLTE call termination event may be logged. The abnormal VoLTE call termination event may be utilized when analyzing the performance of the VoLTE network.

Abstract: Systems and methods for managing timers for Session Initiation Protocol (SIP) that facilitates network communications in an IP Multimedia Subsystem (IMS) are disclosed. Based on monitored network traffic, network performance measures can be determined to form a basis for dynamic configuration of SIP timers, which may reflect real time network status and optimize SIP based network communication.
