Iu UP – Iu User Plane protocol
IuUP protocol is used to carry user plane data across the Iu interface which is associated with a RAB (Radio Access Bearer). Consequently, if several RABs are associated with a particular mobile, each of these RABs will require a separate instance of the IuUP protocol. The IuUP protocol can be found on either the IuCS or IuPS interface.
