In various embodiments, each network slice in the mobile communication network supports at least one of a plurality of service types, and wherein the MM response includes an update result for a service type provided by the primary network slice and a service type provided by the secondary network slice.

Abstract: Sidelink protocols enable user devices to rapidly find, make contact with, and continue communicating with other user devices. For example, vehicles in traffic can communicate on a low-complexity sidelink channel to cooperatively avoid collisions, saving countless lives. Disclosed protocols also enable mobile and IoT devices to form a self-organized temporary local network, independently of base stations. Example messages include a sidelink hailing message configured to discover other user devices, sidelink reply messages indicating the location or identity of each user device, sidelink semaphore messages indicating when each member enters and exits the temporary local network, and extremely fast low-latency emergency communication between vehicles. The disclosed low-complexity protocols may enable cost-constrained use cases that would remain unfeasible under 5G and 6G requirements, absent the systems and methods disclosed herein.

Abstract: A band steering system includes a station and a wireless access point. The station broadcasts a probe request, where the probe request corresponds to a received signal strength indicator. The wireless access point monitors whether the probe request is in a first band or in a second band. When the wireless access point receives the probe request from the first band, the wireless access point determines whether the station is associated with the first band or the second band. When the station is not associated with the first band and the second band, the wireless access point blocks or responds to the probe request according to the received signal strength indicator and a first threshold. When the station is associated with the first band or the second band, the wireless access point blocks or responds to the probe request according to the received signal strength indicator and a second threshold.

Abstract: The current disclosure facilitates the use of intelligent remote radio unites via the use of microservices and modems to make the radio head intelligent. If an enhanced common public radio interface (eCPRI) link is down, the radio head can communicate over the air via the wireless network to an operations, administration and maintenance (OAM) network. Thus, if the microservice is located at the radio head, the microservice can continuously monitor the radio head and evaluate its status. The microservice can then use this information to determine a status (e.g., latency, latency time, or the like) of the radio head and provide that information to the OAM. The microservice can facilitate rebooting or restarting of the radio head and/or run additional testing and/or measures on the link and/or the port of the radio head and provide that information over the air.
