Abstract

There are provided measures for feedback on network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a terminal connected to at least one network slice and being subject to a handover from a source access point to a target access point, receiving a handover command message including handover assistance information indicative of a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, selecting first random access channel resources as attempt random access channel resources from said first pool of random access channel resources, attempting random access to said target access point utilizing said attempt random access channel resources, storing, if said attempting random access to said target access point utilizing said attempt random access channel resources is unsuccessful, attempt related information to an attempt failure list, and transmitting, if said attempting random access to said target access point utilizing said attempt random access channel resources is successful, said attempt failure list to said target access point.
