Method, device and radio access network for adjusting resources of radio access network

A resource adjustment device for a radio access network (RAN), wherein the RAN complies with a specification of an open radio access network (O-RAN) of a 5th generation mobile communication system (5G) and comprises a plurality of radio units (RU), a distributed unit (DU) and a central unit (CU), the resource adjustment device comprising:

• a processing unit, configured to execute a program code;
• and
• a storage unit, coupled to the processing unit to store the program code, wherein the program code is configured to instruct the processing unit to execute a resource adjustment method, the resource adjustment method comprises:
• obtaining a plurality of RAN training information at a first time point;
• predicting a PAN usage condition of a second time point according to the plurality of RAN training information;
• and
• pre-adjusting a PAN resource allocation of the second time point according to the RAN usage condition at a third time point, so as to allocate a plurality of user equipments (UE) to the plurality of RUs and adjust an arrangement of computing resources of the DU and the CU;
• wherein the first time point is earlier than the third time point, and the third time point is earlier than the second time point.
