    Abstract: The present disclosure relates to a technique for steering a Random Access Channel (RACH) a wireless communication network supporting a set of network slices. More specifically, the technique involves generating, at a RAN node, RACH steering information for the set of network slices. The RACH steering information comprises an indication for a UE to select one of available RACH configurations with a RACH configuration-specific probability. In one embodiment, the RACH steering information may be defined based on at least one network slice-specific RACH policy or at least one network slice-specific resource sharing quota provided from a network management entity to the RAN node. In another embodiment, the RAN node may generate RACH steering information based on locally available information about the set of network slices. Once the RACH steering information is generated, the RAN node transmits it to the UE. By using the RACH steering information, it is possible to dynamically adjust a RACH load among multiple network slice-specific RACH configurations and common RACH configurations, thereby efficiently balancing the RACH load (i.e., RACH utilization rate) across the set of network slices.

    Abstract: There are provided measures for network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a target access point being a target of a handover of a terminal connected to at least one net-receiving work slice from a source access point, receiving a handover request including information on said at least one network slice, selecting, from a plurality of pools of random access channel resources to be used for contention-based random access processing, 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, wherein said selecting is based on at least one of network slice related information on terminals in radio resource control idle mode, on terminals in radio resource control inactive mode, and/or on terminals in radio resource control connected mode, and of available random access channel resources, and transmitting a handover request acknowledgement message including handover assistance information indicative of said first pool of random access channel resources.

    Abstract: A master node is provided for a user equipment operating in dual-connectivity with the master node and a secondary node. The master node may be configured to receive information that indicates supported network slices of one or more further nodes. The master node may be configured to transmit slice support information for the one or more further nodes, based on the information. The slice support information may indicate one or more of the supported network slices, at least one non-supported network slice of the one or more further nodes, or at least one communication session of the user equipment that is associated with at least one non-supported network slice. The secondary node may receive the slice support information, and make a secondary node change determination at the secondary node, based on the slice support information.
