Abstract:
A method and apparatus for handling duplicated evolved universal terrestrial radio access network (E-UTRAN) radio access bearers (E-RABs) for dual connectivity in a wireless communication system is provided. A mobility management entity (MME) receives an E-RAB modification indication message including several E-RAB identifiers (IDs) set to the same value, and triggers a user equipment (UE) context release procedure with a cause value.
