Abstract: Systems and methods for locating server nodes in close proximity to edge devices using georouting. Microservers automatically form a global peer-to-peer network to serve edge functions and content to edge devices. Edge devices use HyperText Transfer Protocol (HTTP) to execute serverless functions or otherwise retrieve data from edge nodes located in close proximity to the HTTP client. Serverless functions are implemented in secure, isolated environment utilizing a blockchain.

Abstract: A method and a device for two-step contention based random access are provided. The method includes: sending, by a user equipment (UE), an Msg1 message; and determining that two-step random access of the user equipment is successful, in a case that a UE identifier carried in the Msg1 message is a cell radio network temporary identifier (C-RNTI) and physical layer scheduling signaling addressed based on the C-RNTI is received by the user equipment. For two-step contention based random access, if the UE identifier carried in the Msg1 message is a C-RNTI, the user equipment determines that the two-step random access is successful in a case that the physical layer scheduling signaling addressed based on the C-RNTI is received by the user equipment. In this way, the two-step contention based random access can be achieved.

Abstract: A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

Abstract: A route anomaly detection and remediation system analyzes a prefix for each route received to validate the route. A route monitoring component provides a centralized querying system for all routers from all devices to study routing history. A route collection component receives and stores all routes from multiple routers at a server. A set of microservice analysis components performs prefix analysis on each received route. Each microservice analysis component analyzes one or more portions of the prefix for each route to detect hijacked routes, leaked routes, withdrawn routes and/or other unhealthy routes before the routes are utilized for routing traffic on the network. The analysis performs new prefix validation and identifies healthy routes. Alerts identifying invalid routes are transmitted to an incident management system. Healthy routes are approved for usage by routers on the network to prevent network outages while improving network reliability, availability and stability.
