Abstract

A management apparatus of a Radio Access Network (RAN) that is shared by a plurality of operators, wherein the RAN comprises: a Central Unit (CU); a first Distributed Unit (DU) that is communicably connected to the CU; a second DU that is communicably connected to the CU; and a Radio Unit (RU) that is communicably connected to the first DU and the second DU, wherein the management apparatus comprises a processor that executes transmission of instructions to the CU, the first DU, and the second DU to cause the second DU to process, among data to be processed at the first DU for the RU, at least a portion of data for a specific equipment (UE) that is communicably connected to the RU.

First claim

1 . A management apparatus of a Radio Access Network (RAN) that is shared by a plurality of operators, wherein the RAN comprises:
a Central Unit (CU); a first Distributed Unit (DU) that is communicably connected to the CU; a second DU that is communicably connected to the CU; and a Radio Unit (RU) that is communicably connected to the first DU and the second DU, wherein the management apparatus comprises a processor that executes transmission of instructions to the CU, the first DU, and the second DU to cause the second DU to process, among data to be processed at the first DU for the RU, at least a portion of the data for a specific User Equipment (UE) that is communicably connected to the RU.

2 . The management apparatus according to claim 1 , wherein the specific UE is a UE that entered into a guarantee type Service Level Agreement (SLA) with one of the plurality of operators.

3 . The management apparatus according to claim 1 , wherein the instructions are transmitted
when a resources usage rate of the first DU exceeds a predetermined first threshold, or when traffic being monitored in the RAN exceeds a predetermined second threshold.

4 . The management apparatus according to claim 1 , wherein the portion of the data to be processed at the second DU is determined by a type of the data for the specific UE.

5 . The management apparatus according to claim 4 , wherein the type of the data for the specific UE is defined for each application.

6 . The management apparatus according to claim 1 , wherein the portion of the data to be processed at the second DU is a fixed percentage portion of the data for the specific UE.

7 . The management apparatus according to claim 6 , wherein the fixed percentage portion is selected in resource block units.

8 . A method for managing a Radio Access Network (RAN) that is shared by a plurality of operators, the method comprising:
providing the RAN, wherein the RAN comprises:
a Central Unit (CU),
a first Distributed Unit (DU) that is communicably connected to the CU,
a second DU that is communicably connected to the CU, and
a Radio Unit (RU) that is communicably connected to the first DU and the second DU; and
instructing the CU, the first DU, and the second DU to cause the second DU to process, among data to be processed at the first DU for the RU, at least a portion of the data for a specific User Equipment (UE) that is communicably connected to the RU.

9 . A radio communication system comprising:
a Radio Access Network (RAN) that is shared by a plurality of operators, wherein the RAN comprises a Central Unit (CU), a first Distributed Unit (DU) that is communicably connected to the CU, a second DU that is communicably connected to the CU, and a Radio Unit (RU) that is communicably connected to the first DU and the second DU; and a management apparatus of the RAN, wherein the management apparatus comprises a processor that executes instructing the CU, the first DU, and the second DU to cause the second DU to process, among data to be processed at the first DU for the RU, at least a portion of the data for a specific User Equipment (UE) that is communicably connected to the RU.
