Abstract: A spectrum access system (SAS) grants one or more channels of a shared spectrum to a base station, e.g., in response to receiving a registration request from the base station. The SAS increments a usage of a connection between the base station and the SAS in response to the SAS receiving information indicating that the base station has an active connection with the apparatus during a service time interval. The processor does not increment the usage if the base station does not have an active connection with the apparatus during the service time interval. In some cases, the active connection is indicated by heartbeat messages exchanged between the base station and the SAS. A customer associated with the base station is charged a cost based on the usage determined by the SAS.

Abstract: An apparatus (200) includes a transceiver (204) configured to establish a connection with a spectrum access server (SAS) (115, 116) and a processor (202) configured to monitor a status of the connection. The processor (202) is also configured to modify the connection to the SAS (115, 116) in response to the status indicating a possible failure of the connection. The processor (202) modifies the connection prior to expiration of a timeout interval for the connection to the SAS (115, 116). The apparatus (200) is a Citizens Band Service Device (CBSD) (131-133) or a domain proxy (DP) (130) that aggregates messages for multiple CBSDs.
