Abstract
Provided are methods and apparatuses for off-network key management in one-to-one mission critical data communication. A method includes initiating an off-network MCData service for the communication with an other client device, obtaining a MCData message including a MCdata protection key and an identifier of the MCdata protection key, in case that a valid MCdata protection key for the other client device is not available, and transmitting the MCData message to the other client device.
Claims15
A method for off-network key management in one-to-one mission critical data (MCData) communication by a client device, the method comprising:
- initiating an off-network MCData service for the communication with an other client device;
- obtaining a MCData message including a MCdata protection key and an identifier of the MCdata protection key, in case that a valid MCdata protection key for the other client device is not available;
- and
- transmitting the MCData message to the other client device.
A client device for off-network key management in one-to-one mission critical data (MCData) communication, the client device comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- initiate an off-network MCData service for the communication with an other client device,
- obtain a MCData message including a MCdata protection key and an identifier of the MCdata protection key, in case that a valid MCdata protection key for the other client device is not available, and
- control the transceiver to transmit the MCData message to the other client device.
