The CBRS Alliance and the Alliance for Telecommunications Industry Solutions (ATIS) will cooperate to advance use of the Citizens Broadband Radio Service (CBRS) spectrum band. The organizations say they signed an agreement to address technical challenges and business opportunities for OnGo technology.

Collaboration will focus on technical interworking between the CBRS Alliance and ATIS solutions, including the Home Network Identity (HNI), Priority Services, and Radio Access Networks. 

The work will also address legal and regulatory compliance issues.

The International Mobile Subscriber Identity (IMSI) will get much of the groups’ attention. Traditionally, an HNI identifies a mobile subscriber’s home network and is assignable to mobile network operators with international roaming capabilities. Since the 3550-3700 MHz spectrum is not solely for exclusive use, some users will not directly attain FCC spectrum licenses. 

Instead, users acquire base stations certified by the Commission as being compliant with agency rules. With such broad and low-cost access to the shared licensed spectrum, the ATIS IMSI Oversight Council derived a strategy for allocating blocks of IMSIs for users within the 3.5 GHz CBRS band. A shared HNI identifies CBRS operations, thus conserving HNI resources.

On November 6, the CBRS Alliance Technical Working Group and ATIS hosted a webinar offering an overview of Shared HNI on CBRS and its benefits. The session included an explanation of HNIs, their purpose, the benefits of a Shared HNI compared to a non-shared HNI, and best practices to set up network identifiers in a Shared HNI environment.
