Create a child Actor based on the received message ID

The parent actor creates a child actor based on the identity in the received message, and the same message ID will reuse the child actor. What should I do? I am using this way now.
override def receive: Receive = {
case location: DeviceLocationInfo =>
log.info(s"$location")
val settings = CacheBasicAlarmSettingInRedis(system)
.memoizeInRedisBasicAlarmSetting(location.deviceId)
settings foreach { setting =>
val actorRef = context.child(location.deviceId)
.getOrElse(context.actorOf(Props(new OverSpeedAlarm),location.deviceId))
actorRef ! location
}
case _ =>
}

I use a similar pattern all the time. Have a Map that uses the device ID as the key and an ActorRef as the value -- if there's no entry in the map for a given device ID, create a new child; if there is an entry for a given device ID, then forward the message to the child.
