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: Aspects of the disclosure a method, systems, and a non-transitory computer storage media storing computer-useable instructions for dynamic toggling of voice centricity and data centricity for roaming UEs in a network. The method begins with receiving a request to join a network from at least one UE. The network then determines the radio access technology used by the at least one UE requesting to join the network. Based on the radio access technology used by the at least one UE, the network may then instruct the at least one UE to dynamically toggle from voice centricity to data centricity. The network receives confirmation from the at least one UE that the at least one UE has toggled from voice centricity to data centricity.

Abstract: Providing a voice call includes: receiving, from a user equipment (UE), a request to initiate a voice call traffic session; requesting setup of a voice call data pipe; based on at least a setup of the voice call data pipe not completing prior to a timer event, transmitting voice packets over a signaling data pipe; and based on at least the voice call data pipe setup completing, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe. Placing a voice call includes: requesting, by the UE, to initiate the voice call traffic session; based on at least a first trigger event, transmitting voice packets over the signaling data pipe; and based on at least a second trigger event, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe.

Abstract: A user equipment (UE) can determine when to send an initial request for a voice communication to an Internet Protocol (IP) Multimedia Subsystem (IMS) core of a telecommunication network. For instance, the UE can identify when a call setup instruction should be sent to the IMS to cause a communication channel to be established. The UE can determine whether the UE will experience a change to another radio frequency band or radio technology based on test data, and delay sending the call setup instruction for a time period during which the test data can be analyzed.

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: Systems and methods for controlling carrier aggregation (CA) are disclosed. The method includes determining a communication characteristic describing data communicated between, e.g., 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 or communication slots used to communicate the data to/from the UE.

Abstract: Systems and methods are provided for performing channel estimation in a multiple input multiple output (MIMO) based cellular radio technology (e.g., 4G, 5G). Initially, the reference transmission receive power (RSRP) is reported for each antenna element, rather than as a single RSRP. This enables the base station to understand the channel condition for each MIMO transmission/reception. Using that understanding, the base station can determine the radio-frequency (RF) power level per antenna port to provide more enhanced transmission towards a specific UE, resulting in a better service experience. In other words, more accurate channel estimation based on actual RF conditions of a particular UE can be derived so the base station can tune to the actual need of the UE.

Abstract: Systems and methods are provided for dynamically adjusting a 4G LTE reference signal power level to match a 5G New Radio (NR) coverage footprint to avoid voice over 4G fallback failures for 5G subscribers. Initially, a subscriber making a voice call while in NR coverage may be directed to fall back to LTE in a process known as voice over evolved packet system fallback (VoEPSFB). If the LTE signal strength is worse due to non-optimal settings of the LTE reference signal, the subscriber experiences call setup failure. After the call setup failure, the UE transitions back to the gNodeB. Since the gNodeB knows the UE attempted to fall back to LTE (as well as how soon the UE transitioned back to the gNodeB), a notification is triggered that instructs the LTE base station to increase its reference signal power level.

Abstract: Processes and systems for identifying and removing non-functional Internet-of-Things (IoT) devices from a cellular network are discussed herein. In one example, a probability distribution function of a data profile transmitted by a type of IoT devices is generated. The probability distribution function may be chosen based on a known distribution such as a Gaussian, Bessel, or linear regressive model. The probability distribution function may be empirically generated by applying data received from IoT devices to a machine learning model using supervised or unsupervised learning. After generating the model representing the expected data profile of data received from a type or class IoT devices, data transmitted by the IoT devices may be applied to the model to determine whether the IoT devices are functional or non-functional. Non-functional IoT devices may be removed from the cellular network.

Abstract: Systems may comprise a connectivity manager application operating on a User Equipment (UE) for optimal and secure performance of local applications and improving user experience by optimizing application performance (e.g., detecting data stall events). The systems may monitor incoming internet protocol (IP) packets for one or more applications operating on the UE. The connectivity manager application may detect a drop in a rate at which the IP packets are received over a period of time and determine to reregister and/or reattach to a different node within a network or at a new network.

Abstract: Solutions for dynamically toggling physical downlink control channel (PDCCH) interleaving include: a base station receiving radio measurement reports from a user equipment (UE); based on at least the radio measurement reports, determining that radio reception by the UE meets a threshold; based on at least meeting the threshold, ceasing to interleave data on the PDCCH. The base station continues to monitor radio measurement reports from the UE, and based on at least the radio measurement reports indicating that radio reception by the UE meets a second threshold, resuming interleaving data transmitted on the PDCCH. In some examples, UEs are managed in broadcast groups (e.g., UEs within a common in a cell sector), and interleaving or ceasing interleaving is based on a determination of whether all UEs in the broadcast group are able to forego interleaving.
