The communication apparatus includes a detection unit configured to detect closure of a door of a vehicle, an authentication processing unit configured to determine, in response to detection of the closure of the door by the detection unit, whether a specific mobile device is inside the vehicle by executing a first authentication process corresponding to a vehicle operation for which a highest security is set, among a plurality of vehicle operations that can be requested by the user, and an execution unit configured to execute, when the authentication processing unit has determined that the specific mobile device is inside the vehicle, a requested vehicle operation requestable from an inside of the vehicle and included in the plurality of vehicle operations. ## Claims ### Claim 1 A communication apparatus configured to execute authentication via wireless communication with a mobile device, and, based on an authentication result, control execution of a vehicle operation requested by a user, the communication apparatus comprising: a detection unit configured to detect closure of a door of a vehicle; an authentication processing unit configured to determine, in response to detection of the closure of the door of the vehicle by the detection unit, whether a specific mobile device is inside the vehicle by executing a first authentication process corresponding to a vehicle operation for which a highest security is set, among a plurality of vehicle operations that are possible to be requested by the user; and an execution unit configured to execute, when the authentication processing unit has determined that the specific mobile device is inside the vehicle, a requested vehicle operation that is requestable from an inside of the vehicle and that is included in the plurality of vehicle operations. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein: the plurality of vehicle operations includes a door locking operation that locks the door of the vehicle from an outside of the vehicle; the authentication processing unit is configured to determine whether the specific mobile device is outside the vehicle by executing a second authentication process different from the first authentication process when it is determined by the first authentication process that the specific mobile device is not inside the vehicle, and the door locking operation is requested; and the execution unit is configured to execute the door locking operation for the vehicle when it is determined by the second authentication process that the specific mobile device is outside the vehicle. ### Claim 3 (depends on 2) The communication apparatus according to claim 2, wherein the execution unit is configured to output an alarm when it is determined by the first authentication process that the specific mobile device is inside the vehicle and the door locking operation is requested. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, wherein the plurality of vehicle operations includes a vehicle start-up operation that starts up the vehicle based on an operation of a start-up switch of the vehicle, and the execution unit is configured to execute the vehicle start-up operation without executing an additional process when it is determined by the first authentication process that the specific mobile device is inside the vehicle and the vehicle start-up operation is requested. ### Claim 5 (depends on 4) The communication apparatus according to claim 4, wherein the execution unit is configured to output an alarm when it is determined by the first authentication process that the specific mobile device is not inside the vehicle and the vehicle start-up operation is requested. ### Claim 6 A communication method of executing authentication via wireless communication with a mobile device, and, based on an authentication result, controlling execution of a vehicle operation requested by a user, by a communication apparatus, the communication method comprising: detecting closure of a door of a vehicle; determining whether a specific mobile device is inside the vehicle by executing, in response to detection of the closure of the door of the vehicle, a first authentication process corresponding a vehicle operation for which a highest security is set, among a plurality of vehicle operations that are possible to be requested by the user; and executing a requested vehicle operation that is requestable from an inside of the vehicle and that is included in the plurality of vehicle operations when it is determined by the first authentication process that the specific mobile device is inside the vehicle. ### Claim 7 (depends on 6) The communication method according to claim 6, wherein the plurality of vehicle operations includes a door locking operation that locks the door of the vehicle from an outside of the vehicle, and the communication method further comprising: determining whether the specific mobile device is outside the vehicle by executing a second authentication process different from the first authentication process when it is determined by the first authentication process that the specific mobile device is not inside the vehicle and the door locking operation is requested; and executing the door locking operation of the vehicle when it is determined by the second authentication process that the specific mobile device is outside the vehicle. ### Claim 8 (depends on 7) The communication method according to claim 7 further comprising outputting an alarm when it is determined by the first authentication process that the specific mobile device is inside the vehicle and the door locking operation is requested. ### Claim 9 (depends on 6) The communication method according to claim 6, wherein the plurality of vehicle operations includes a vehicle start-up operation that starts up the vehicle based on an operation of a start-up switch of the vehicle, and the communication method further comprising executing the vehicle start-up operation without executing an additional process when it is determined by the first authentication process that the specific mobile device is inside the vehicle and the vehicle start-up operation is requested. ### Claim 10 (depends on 9) The communication method according to claim 9 further comprising outputting an alarm when it is determined by the first authentication process that the specific mobile device is not inside the vehicle and the vehicle start-up operation is requested.
