Abstract: A cloud control element distributes security keys prior to roaming to facilitate fast transition roaming across different IP subnets. The cloud control element distributes security keys to access points identified as neighboring and sharing a common SSID (service set identifier), but over different IP subnets. The security keys embed information related to authentication by stations for a specific SSID. Responsive to connecting with a specific wireless station roaming to a target access point from a source access point, fast transition by way of a security key is utilized to authenticate the specific wireless station without a full authentication protocol through a RADIUS server.

Abstract: Techniques for providing a backup network path using a standby wide area network (WAN) link with reducing monitoring. Packet loss and latency metrics are monitored for network paths in an adaptive private network (APN) connecting a first user and a second user according to control traffic operating at a first control bandwidth for each network path. A determination is made that a first network path uses a standby WAN link, has packet loss and latency metrics indicative of a good quality state, and has at least one characteristic that identifies the first network path as a backup network path. The control traffic is then reduced for the backup network path to a second control bandwidth substantially less than the first control bandwidth. The backup network path is made active when the number of active network paths is less than or equal to a minimum number.

Abstract: Embodiments of a system and method for random access and scheduling request for new radio things sidelink are generally described herein. In some embodiments, a nUE (network user equipment) schedules a RA (random access) resource in a control channel. The nUE decodes a TAS (transmitter resource acquisition and sounding) payload, received from a wUE (wearable user equipment) in a PRB (physical resource block) addressed to a RA-ID (random access identifier) associated with the nUE. The nUE encodes, in response to decoding the TAS payload, a RAS (receiver resource acknowledgement and sounding) payload in the PRB. The nUE decodes initial access content received via a data channel from the wUE, the initial access content including a pro posed temp ID (temporary identifier) for addressing the wUE. The nUE encode, in response to the initial access content, an ACK (acknowledgement), addressed to the wUE, to accept initial access of the wUE.
