Abstract: A computer apparatus, such as a validator node, for validating incident-related data records in a distributed electronic ledger is configured to receive a request from an agent to add a proposed incident-related data record associated with an incident to the distributed electronic ledger. In response to the proposed incident-related data record, the computer apparatus determines, from the distributed electronic ledger, one or more attributes of the agent or incident. The computer apparatus determines whether the proposed incident-related data record satisfies validation criteria based at least partially on the one or more attributes of the agent or incident. Once validated, the computer apparatus may then append the proposed incident-related data record to the distributed electronic ledger. Alternatively, the proposed incident-related data record may be appended regardless of validity, but an indication of validity may be appended if the proposed incident-related data record is validated.

Abstract: A method for registering an Internet of Things (IoT) device to an incident IoT ledger system is provided. A computer aided dispatch (CAD) device sends a first ledger request including an incident record to a distributed incident ledger operated by validation nodes. The CAD device receives a first ledger response indicating that the incident record was accepted and added into the incident ledger after being validated by the nodes. The CAD device then sends a second ledger request to an IoT distributed ledger operated by second validation nodes. The request includes a query to the IoT distributed ledger to find registered IoT devices for affiliating with the incident. The CAD device receives a second ledger response including information identifying registered IoT devices from the IoT distributed ledger. The CAD device then sends an affiliation invitation to an IoT device determined from the registered IoT devices identified in the second ledger response.

Abstract: A communication pathway (145) can be established between physically collocated narrowband (135) and broadband (105) devices. The narrowband device (135) can identify a communication channel. A transmission frequency used by the broadband device (105) can be spectrally-proximate to a reception frequency used by the narrowband device (135) in a frequency range associated with the communication channel, resulting in interference of the narrowband device's (135) reception when the broadband device (105) is transmitting and the narrowband device (135) is receiving concurrently. The narrowband device (135) can instruct the broadband device (105) to switch to a transmission spectrum block that is spectrally separated from the reception spectrum block of the communication channel to minimize interference between the devices when the narrowband device (135) handles a call assignment.
