US 11,889,508 B1 · System and method for managing a cellular network

Abstract

A system for managing a cellular network implemented based on O-RAN standards includes an O-DU for generating a first control-plane message requesting a first set of radio resources responsive to a scheduled uplink transmission from a user device, where the first set of radio resources includes an assigned portion of a carrier signal allocated for the uplink transmission; an interposer unit for receiving the first control-plane message, and generating a second control-plane message requesting a second set of radio resources including a remaining portion of the carrier signal; and an O-RU for receiving the first and second control-plane messages, receiving the uplink transmission, and generating user-plane message(s) including first and second digitized data correlated with the first and second control-plane messages. The interposer unit sends the first digitized data to the O-DU without sending the second digitized data, and monitors the carrier signal using the first and second digitized data.

A system for managing a cellular network implemented based on Open Radio Access Network (O-RAN) standards, the system comprising:

an O-RAN distributed unit (O-DU) configured to generate a first control-plane message requesting a first set of radio resources responsive to a scheduled uplink transmission from a user device, wherein the first set of radio resources comprises an assigned portion of a carrier signal allocated for the uplink transmission;
an interposer unit configured to receive the first control-plane message from the O-DU, and to generate a second control-plane message requesting a second set of radio resources, wherein the second set of radio resources comprises a remaining portion of the carrier signal not allocated for the uplink transmission;
and
an O-RAN radio unit (O-RU) configured to receive the first control-plane message and the second control-plane message from the interposer unit, to receive the uplink transmission from the user device, and to generate at least one user-plane message comprising first digitized data from the uplink transmission correlated with the first control-plane message and second digitized data from the uplink transmission correlated with the second control-plane message,
wherein the interposer unit is further configured to receive the at least one user-plane message from the O-RU, to send the first digitized data to the O-DU without sending the second digitized data to the O-DU, and to monitor the carrier signal using both the first digitized data and the second digitized data.
