Abstract: Systems, methods, and computer-readable media are described for delivering wireless telecommunications services using the Voice over Long Term Evolution (VoLTE) protocol, the Video over Long Term Evolution (VoLTE) protocol, and other such protocols that implement the Real-Time Transport Protocol (RTP) to deliver packet flows to mobile devices. Metrics relating to the RTP packet flow may be generated, and may be collected from a mobile device periodically or on an as-needed basis. The RTP-based metrics may be utilized to determine that an LTE inter-frequency handover should be performed. Inter-frequency handover criteria may specify thresholds for RTP metrics within an individual reporting period, or may be used to determine that an inter-frequency handover will occur if a rolling or weighted average of RTP metrics satisfies a threshold.

Abstract: A system and method may improve service setup time and reliability for user equipment (UE) fallback procedures in cellular networks. Logic in the UE may define an event to trigger a measurement report and send that measurement report to the base station upon initiating fallback procedures. This event and measurement report may allow the 5G base station (g-NB) to know which frequency is going to be the best choice at the time of setting up the voice service by looking at radio signal strength indicators coming from the 5G UE for each frequency in the measurement report. Incorporating the measurement report process into the logic of the UE for call setup that also includes the fallback process for may result in substantially faster call setup time as well as better voice call success rate.

Abstract: Systems and methods for deriving and providing mobile device locations are disclosed. The method includes a communication network detecting one or more triggering conditions.

Abstract: Systems and methods for performing Evolved Packet System (EPS) fallback from a 5G system to an Evolved Packet Core (EPC) system are disclosed. The method, performed in a mobile device, detects a communication at the mobile device. The method then determines whether either the mobile device or a base station supports the communication over new radio. Directly in response to determining that either one of the mobile device or the base station does not support the communication over new radio, the method generates and transmits an EPS fallback message from the mobile device to the base station, wherein the EPS fallback message instructs the base station to initiate a fallback procedure from the 5G system to the EPC system.

Abstract: Systems and methods for controlling carrier aggregation (CA) are disclosed. The method includes determining a communication characteristic describing data communicated between user equipment (UE) and a communication endpoint. The communication characteristic is used to generate a CA trigger that controls at a communication node a number or assignment of component carriers used to simultaneously communicate the data to/from the UE.

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: A method for making device to device calls is disclosed. A 5G cellular network that is New Radio (NR) enabled is provided in a first geographic location. A first user equipment (UE) device that is NR enabled in the first geographic location is identified. A request to make a voice call using the NR from the first UE device that is NR enabled is received. The request originates from a second UE device that is not NR enabled. The first UE device is within a range of the second UE device. In response to receiving the request to make the voice call, the voice call is sent over the 5G communications network.

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 and methods for controlling carrier aggregation (CA) are disclosed. The method includes determining a communication characteristic describing data communicated between user equipment (UE) and a communication endpoint. The communication characteristic is used to generate a CA trigger that controls at a communication node a number or assignment of component carriers used to simultaneously communicate the data to/from the UE.

Abstract: Systems and methods for maintaining and dynamically updating inactivity timers at a user equipment to detect a one-way audio or mute call to improve call experience are disclosed. The method enables the user equipment to perform a set of actions (e.g., enable, disable, drop call, don't drop call, etc.) when a one-way audio or mute call is detected. Values for the timer and/or action parameters can be dynamically determined and/or communicated to the user equipment by a telecommunications service provider based on one or more of the following factors: network health, network congestion, current events, type of call (e.g., emergency, non-emergency), type of customer (e.g., business, premium, residential, etc.), service-level agreement, and so on. Values for the timer and/or action parameters can be configurable based on a location.

Abstract: Processes and systems for determining perceived signal strength indicator values of a cellular signal transmitted by a base station within a coverage region are discussed herein. In one example, user equipment measures signal strength indicator values for a cellular signal in a coverage region. A base station receives the signal strength indicator values measured by the user equipment and generates a signal strength indicator map using the received values and respective locations of the user equipment that measured the received values. Data indicative of the signal strength indicator map is transmitted to user equipment to guide users of user equipment to move to a region in the coverage region that has a greater perceived signal strength indicator for the cellular signal.

Abstract: Systems and methods for maintaining and dynamically updating an inactivity timer at a user equipment to detect a one-way audio or mute call to improve call experience are disclosed. The method enables the user equipment to perform an action (e.g., enable, disable, drop call, don't drop call, etc.) when a one-way audio or mute call is detected. Instead of hardcoding values for the timer and/or action parameters within the user equipment (for example, by an original equipment manufacturer (OEM)), these parameter values can be dynamically determined and communicated to the user equipment by a telecommunications service provider based on one or more of the following factors: network health, network congestion, current events, type of call (emergency v. non-emergency), type of customer (business, premium, residential, etc.), service-level agreement, and so on.

Abstract: A standalone mobile device that is not configured to handle voice over 5G is configured to automatically disable its 5G NR radio such that the NR radio is inoperable with respect to 5G networks, e.g., the mobile device cannot connect to a NR base station. The disabling of the mobile device's ability to connect to a 5G network may be event triggered, where an example of the event may be that the mobile device is handling a VoWiFi call. When the mobile device is handling a VoWiFi call and the VoWiFi call needs to be handed over to a cellular network, then the mobile device may perform the handover procedure of the VoWiFi call to an LTE network rather than first attempting to hand the VoWiFi call over to a 5G network via an EPS-FB procedure. When the call ends, the mobile device may re-enable its NR radio.

Abstract: Systems and methods for categorizing communication data are described herein. The systems and methods enable an IMS core network to register a user equipment as a 5G-capable device and store communication data in a manner that differentiates the communication data from non-5G devices. Once identified as a 5G-capable device and information that 5G coverage is available is received, the registration message from the user equipment to the IMS core is modified to configure the IMS core to store the communication data as 5G communication data rather than non-5G communication data.

Abstract: Systems and methods for characterizing communications in a network are disclosed.
