Abstract: A method is disclosed for reducing processor utilization at a cellular base station, comprising: sending a number of random access preambles in a System Information Block (SIB) that may be less than 64; subtracting the number of random access preambles from 64 to obtain a ceiling of dedicated preambles; and using root sequences to generate a number of dedicated preambles less than or equal to the number of random access preambles, thereby reducing processor utilization relative to generating 64 preambles.

Abstract: A method, computer-readable media and system for providing Random Access Channel (RACH) response preamble prioritization are presented. In one embodiment a method includes receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups; providing, by the PPE, an ordered prioritized list of the detected preambles; and forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list.

Abstract: Methods and systems are presented for providing a 4G-5G Open RAN User Plane Path. In one embodiment a method includes keeping, by a Distributed Unit (DU)/Centralized Unit (CU)-User Plane (UP), a list of local switch enabled subscribers; receiving an uplink data packet for a local switch enabled subscriber from a source device; comparing , by the DU/CU-UP, if a destination Internet Protocol (IP) address matches with any of IP addresses in the local switch enabled subscriber destination device IP addresses; and when the destination IP address matches, then switching by the DU/CU-UP the traffic and sending the data packet as a downlink traffic towards the destination device.
