Abstract
A system described herein may provide for an interface, such as a midhaul interface, between one or more radio elements of a radio access network (“RAN”), such as a Distributed Unit (“DU”) and/or a radio unit (“RU”), and higher layer functions of the RAN, such a Central Unit (“CU”). The interface may provide for the DU to be communicatively coupled to multiple CUs, which may be associated with multiple distinct core networks. The system may route uplink traffic, received from User Equipment (“UEs”) via the RU and the DU, to an appropriate CU. The system may resolve conflicting instructions, for the DU, received from different CUs. The resolution may be performed based on relative priority levels of the CUs or other factors. The system may provide for granular monitoring of traffic parameters on a per-CU basis, thus preserving the privacy of different core networks.
