The method includes generating, by a first communication circuitry, a first message that identifies a radio access technology. The first message is of a first message type. The method also includes sending, by the first communication circuitry, the first message to a second communication circuitry. The first communication circuitry and the second communication circuitry communicate with each other over a non-radio link. The method further includes sending, by the first communication circuitry, a second message associated with the first message. The second message is of a second message type that is different from the first message type. ## Claims ### Claim 1 A method for identifying a radio access technology by an electronic device, comprising: generating, by a first communication circuitry, a first message that identifies a radio access technology of the first communication circuitry, wherein the first message is of a first message type;
