Abstract:
Digital signal processors (DSPs) process the digital baseband signals associated with CPRI links between BBUs and RRHs. The DSPs may be implemented at the RRH nodes (e.g., at the link leading to the BBU node), at the BBU node (e.g., at the links leading to the RRH nodes), or at both. The DSPs may be used to increase performance of the RAN. For example, the DSPs may implement digital filters designed to enhance the performance of the RAN.
Abstract:
A system may be configured to determine a floor of a building in which the user device is located at a time a call was placed. The information, indicating the determined floor, may be provided to a callee, such as a public safety answering point (“PSAP”). The floor may be determined based on, for example, comparing an altitude of the user device and/or a list of networks or devices that are visible to the user device, to a set of reference information.
Abstract:
A device may receive, from a network device, a user equipment (UE) parameter update request notification indicating an update to a UE parameter of a universal subscriber identity module (USIM), and may generate an encrypted UE parameter update request. The device may cause the encrypted UE parameter update request to be provided to the USIM to cause the USIM to update the UE parameter and to generate an encrypted UE parameter update response. The device may receive, from the network device, the encrypted UE parameter update response, and may verify an authenticity of content of the encrypted UE parameter update response based on whether the encrypted UE parameter update response is signed by the USIM. The device may provide, to the network device, a result indicating whether the UE parameter is updated and whether the authenticity of the content of the encrypted UE parameter update response is verified.

Abstract:
A user device may be used to prevent a user from driving a vehicle while distracted by the user device. The user device may create a user profile, determine whether the user is driving, and collect usage data while the user is driving. The user profile may include information regarding the driver's propensity to be distracted while driving and the usage data may include information on whether the user is actually distracted by the user device. The user device may determine whether the driver is distracted based on the user profile and the usage data, and may respond in one or more ways, such as by alerting the driver with an audio signal, disabling a feature of the user device, logging instances of user distraction with a diagnostics device, activating a braking system of the vehicle, warning nearby drivers about the driver being distracted, and more.
Abstract:
A system may be configured to receive analytics information regarding a cell of a wireless telecommunications network. The cell may be associated with multiple carriers, which may each be associated with, for example, a particular radio access technology (“RAT”), frequency band, or frequency sub-band. The system may dynamically rank the carriers based on measures of load associated with the carriers (as indicated by the analytics information), and may generate system information blocks (“SIBs”) that include the dynamic rankings. The SIBs may be provided to user devices, which may select carriers, via which to connect to the cell, based on the dynamic rankings.
Abstract:
A device is configured to obtain interference information indicating interference levels at frequencies. The device is configured to determine a frequency for a small cell to use to communicate with a client device based on the interference information. The small cell is capable of using the frequencies to communicate and the frequency is determined from among the frequencies. The device is further configured to provide frequency information to the small cell instructing the small cell to communicate with the client device using the frequency.
Abstract:
A method, a device, and a non-transitory storage medium to obtain a traffic volume value that indicates a volume of traffic to and/or from a radio node, a value that indicates a class of the radio node, or a received signal strength value that indicates a received signal strength of a macro signal received by the radio node; calculate a delay time value based on traffic volume value, the value that indicates the class, or the received signal strength value; and transmit the delay time value to the radio node, wherein the delay time value indicates a time period to wait, by the radio node, before attempting to authenticate and register with one or more network devices.
Abstract:
A network device may select one or more secondary bands in a spectrum based on a measure of quality of the one or more secondary bands; transmit information identifying the one or more secondary bands to an end unit; code, based on a coding scheme, a data flow to obtain multiple data signals that represent the data flow; and transmit, towards the end unit, the multiple data signals via the one or more secondary bands and a primary band.
Abstract:
A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an radio access management service. The radio access management service may include calculating a predicted total resource allocation value for a prospective access and transmission grant associated with a prospective time window, and a value indicating a number of end devices that can be supported. The service may generate and transmit an access and transmission grant message directed to end devices, based on the value, in which the message may include both random access response information and contention resolution information.
