Since Mimihagi was originally part of the Soul King, it would make sense that it would share the king's power over the barriers seperating Soul Society and the royal dimension, but since it usually protects the palace it is probably the king and/or royal guard who send it down during times of emergency. However, if they were unable to for some reason then Ukitake might be able to summon them.
