Abstract:
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.
