Abstract: A system collects handles of entities registered to post content on online platforms and stores the handles on a blockchain network. The stored handles can mitigate the effects of being deplatformed from the online platforms. In one example, the system registers global identifiers that each uniquely identify an entity. The system receives and indexes handles of various online platforms based on the global identifiers. The indexed handles that are stored on the blockchain network can be searched by followers of a deplatformed entity for an alternative online platform on which the deplatformed entity posts content.

Abstract: This document describes techniques, apparatuses, and systems for autonomous delivery to a dynamic location. A user requests delivery of an item. An autonomous vehicle carrying the item navigates to a delivery location associated with the request. While navigating the autonomous vehicle toward the delivery location, the autonomous vehicle receives one or more estimates of a current location of a wireless device of the user. In response to receiving a respective estimate, the autonomous vehicle updates the delivery location to match the respective estimate of the current location of the wireless device. In this way, the delivery location can be dynamically updated as the user changes location. Once the autonomous vehicle reaches the delivery location, the item can be delivered to the user.

Abstract: Aspects of the subject disclosure may include, for example, monitoring status of a network configured to provide end-to-end delivery of services to priority user equipment authorized according to a prioritized class of service and other user equipment not authorized for the prioritized class of service. The prioritized class of service extends a reserved network capacity for end-to-end delivery of a service via first domain including first network slices and a second domain including second network slices. A network interruption compromising the reserved capacity is determined based on the monitored status and integration of an alternate group of slices into one of the first network domain, the second network domain, or both to replace the compromised group of slices, is orchestrated. Integration of the alternate group of slices restores reserved network capacity according to the prioritized class of service. Other embodiments are disclosed.

Abstract: Described herein are techniques and systems for selectively transitioning communication sessions from TDD to FDD based on service type and uplink quality. The selective transitioning of communication sessions from TDD to FDD can provide higher and more reliable uplink throughput to UEs, as needed. An example process includes determining, during setup of a communication session for a UE using TDD, a type of service associated with the communication session, and determining that the type of service is a predefined service of a set of predefined services. The example process may further include determining a value indicative of a quality associated with an uplink connection established by the UE, determining that the value fails to satisfy a threshold value, and transitioning, based at least in part on the value failing to satisfy the threshold value, the communication session to a target base station to finish the setup using FDD.

Abstract: The system receives, from a telecommunications network subscribed to by the wireless device, a list of roaming networks. The system connects to a roaming network from the list of roaming networks. The system enters a roaming mode from a standard mode. The roaming mode reduces the amount of data used by the wireless device by preventing the wireless device from performing background tasks. Background tasks include processes performed by the wireless device to keep an application on the wireless device up to date. The standard mode causes the wireless device to operate at a higher data level and a less optimized battery level compared to the roaming mode. The system connects to the telecommunications network. The wireless device disconnects from the roaming network before connecting to the telecommunications network subscribed to by the wireless device. The system enters the standard mode.
