CBRS Alliances Collaborates with ATIS for 3.5 GHz Sharing
Tuesday, December 18, 2018 | Comments

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

Collaboration will focus on the technical interworking between the CBRS Alliance and ATIS solutions, including the international mobile subscriber identity (IMSI), home network identity (HNI), priority services and radio access networks (RANs). The work will also address legal and regulatory compliance topics.

“The CBRS Alliance values working with ATIS as one of the most respected industry associations in the telecommunications sector,” said Alan Ewing, executive director of the CBRS Alliance. “We're looking forward to tackling technical challenges that may be associated with delivering commercial service in the 3.5 GHz band and to maximizing cooperation between our organizations.”

As part of the liaison agreement, the organizations will partner on HNI initiatives within the 3.5 GHz CBRS band. Traditionally, an HNI identifies a mobile subscriber’s home network and is assignable to mobile network operators with international roaming capabilities. Since the 3.5 GHz spectrum is not solely for exclusive use, some users will not directly attain FCC spectrum licenses. Instead, users acquire base stations certified by the FCC as being compliant with the FCC rules.

With such broad and low-cost access to the shared licensed spectrum, ATIS’ IMSI Oversight Council (IOC) derived a strategy for allocating blocks of IMSIs for users within the 3.5 GHz CBRS band. Within the 3.5 GHz band, a shared HNI is used to identify CBRS operations, thus conserving HNI resources.

“Earlier this year, ATIS and the CBRS Alliance achieved a key milestone in enabling use of CBRS spectrum to improve mobile connectivity and make it more widely available,” said Susan Miller, president and CEO of ATIS. “This new agreement affirms that we will continue our collaboration with the CBRS Alliance, which has been effective in creating infrastructure to utilize the 3.5 GHz CBRS band for LTE (Long Term Evolution) services, while also advancing IoT (internet of things) applications.”
