After the CBSD is discovered by the SAS server and authentication is complete, the CBSD creates a secure session with the SAS and begins the registration procedure by sending a registration request.
The registration request includes the following parameters:
configured CBSD user ID
FCC ID:
for the 7705 SAR-Hmc NA (3HE12472AAAB): AS57705SARHMC-1
for the 7705 SAR-Hmc NA variant 2(3HE12473AAAA): AS57705SARHMC-2
For both nodes, the FCC ID is used for CBRS B48 CBSD categories A and B.
CBSD serial number
configured CBSD category
The CBSD category supplied in the registration request and the category configured in the CLI must match.
air interface — set to E-UTRA, as defined in the Wireless Innovation Forum Signaling Protocols and Procedures for Citizens Broadband Radio Service (CBRS): WInnForum Recognized CBRS Air Interfaces and Measurements, Document WINNF-17-SSC-0002
If the CBSD had any existing grants with the SAS before sending the registration request, they are deleted.
The SAS sends the CBSD a registration response that contains the following parameters:
CBSD ID
response — an indication of whether the registration request is approved
The CBSD ID is stored by the CBSD and used for all subsequent procedures with the SAS.
If the registration request fails for any reason, the CBSD retries the request every 60 s.
