Various communication systems may benefit from appropriate indication of support for communication protocols. In particular, certain wireless systems that use handover may use selective proprietary protocol support indication removal. A method can include determining protocol support based on a first configuration received from the source access node. The method can also include determining whether to continue, after a handover, using a proprietary protocol based on whether a first configuration remains unchanged. The method can further include using or ceasing from using the proprietary protocol based on the determination.
