Socket 통신으로 인한 서비스에서 데이터 보내기

    socket = new Socket(SERVERIP, SERVERPORT);

 @Override

  super.onDestroy();
  try {
   socket.close();
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();

  socket = null;
 }

}

우선 소스는 이렇구 소켓 통신으로 액티비티간에 유지시키려고 서비스로 소켓을 연결까지

됩니다. 그런데 여기서 데이터를 어떻게 보내야 하나요?
