Abstract: In certain embodiments, a (CBSD) base station for a (CBRS) radio system transmits new information elements in an existing capability exchange message to a spectrum access system (SAS) informing the SAS as to whether the SAS should transmit a channel-change message to the base station either (i) directly (and despite of domain proxy being present in the communication path) or (ii) via a domain proxy. If and when the SAS subsequently receives notification of incumbent activity from an Environmental Sensing Capability system, the SAS transmits either a new channel-change message or includes new information elements in an existing heartbeat message to the base station either (i) directly or (ii) via the domain proxy per the capability exchange message. The SAS can combine multiple channel-change messages for multiple base stations into a single message for transmission to a domain proxy that can communicate with those multiple base stations, thereby reducing communications to and from the SAS and decreasing the time that it takes to change channels without jeopardizing existing traffic.
