  • Method and apparatus for monitoring SAS CPAS performance in CBRS systems
    Patent number: 11368854
    Abstract: A method for monitoring performance of Cooperative Periodic Activity between Spectrum Access Systems (CPAS) process in a network operating Citizens Broadband Radio Service (CRBS). The method comprises performing a first check of a status of a transmission Grant of a Citizens Broadband Radio service Device (CBSD) at the start of the CPAS process and if the result of the first check indicates that the Grant is suspended then performing a second check of the status of said transmission Grant at the end of the CPAS process. The method further comprises raising an alarm if the result of the second check indicates that the Grant is suspended. An apparatus and a network implementing the method are also disclosed.
