An emergency determining system configured as part of a cellular or mobile network to receive emergency data from public safety answering points and to evaluate the emergency based at least in part on third party data, network data, and the emergency data. For instance, the emergency determining system may determine a level, a geographic area, and/or a response to the emergency and to broadcast, via the cellular or mobile network, notifications to individual's personal electronic devices within the geographic area to alert the individuals to the emergency and to provide instructions related to an appropriate response by the individual.

System and method for generating localized emergency warnings

A node of a radio access network (e.g., a cellular network) can receive a revocation message revoking a spectrum grant (e.g., a Citizens Broadband Radio Service, CBRS, discontinuation notice). The node can determine a first group of terminals that are in communication with the node via wireless resources within the spectrum grant. The node can, in response to the revocation message, trigger respective inter-band handovers of the terminals of the first group of terminals. In some examples, a system includes a domain proxy that receives a grant message indicating the spectrum grant; notifies the node; subsequently, receives a revocation message revoking the spectrum grant; and sends a handover command to the node in response to the revocation message. The spectrum grant can be located within 3GPP band forty-eight or other bands.

Inter-frequency handover

Techniques for proxy based network access are discussed herein. In some examples, the techniques can be implemented in a network proxy device for Citizens Broadband Radio Service (CBRS). A base station or a domain proxy device may manage or otherwise use CBRS resources by exchanging signaling messages with a Spectrum Access System (SAS). The base station or domain proxy device may transmit signaling messages in a first private network to a network device bridging the first private network and a second private network with limited access to a public network. The network device send proxy message(s) in response to the signaling messages to the SAS and can establish an encrypted session layer or application layer tunnel between the base station and/or domain proxy device. The proxy based network access preserves secure networks while still allowing limited messaging with other public or private networks.
