The generation, modification and recovery (or deletion) of each agent entity are controlled and completed by a main control entity.
The agent entity is composed of process flows (processes), a resource information database supporting the flows, and operations for the flows. For example, according to current 3GPP, a CU logical node has protocol stack functions such as RRC/SDAP/PDCP.
The proxy entity may be the following CU function instance: RRC connection (radio link control connection) controls all related procedures, a resource information database storing RRC connection, and a control operation of the corresponding procedure.
The main control entity generates an RRC Connection instance on a DU, which includes RRC Connection setup, reconfiguration, delete, failure and other flows, stores a resource information database (including RRC Connection ID, configured SDAP/PDCP parameters, operation records or state machines for mutual conversion between the four flows), and specified operation and decision rules for mutual conversion between the four flows.

the master control entity generates a deleting instruction for deleting the corresponding agent entity according to the indication information for deleting the agent entity, and deletes the connection relation between the agent entity and the corresponding distribution unit DU;
and the main control entity deletes the agent entity according to the deletion instruction.
13. The information processing method of a node device according to claim 10, wherein the generating, by the master entity, the instruction of the management agent entity according to the function template includes:
the main control entity receives the indication information of agent entity reconfiguration sent by the operation and maintenance unit, selects a function template from the function templates of the various protocols according to the indication information of agent entity reconfiguration, and modifies the original function template according to the selected function template;
the master control entity reconfigures the primary physical entity according to the modified function template to generate a reconfiguration instruction, and reconfigures the connection relationship between the primary physical entity and the distribution unit DU;
and the main control entity carries out generation configuration on the agent entity according to the reconfiguration instruction.
14. The information processing method of a node device according to claim 9, further comprising:
the main control entity receives an interaction request sent by a first proxy entity in the at least two proxy entities;
the main control entity selects a second proxy entity from other proxy entities except the first proxy entity in the at least two proxy entities according to the interaction request, and establishes a connection relationship between the first proxy entity and the second proxy entity;
and after receiving the response of the second proxy entity, the main control entity configures the first proxy entity and the second proxy entity to interact.
15. The information processing method of a node device according to claim 9, further comprising:
the master control entity receives a switching request or a reported measurement sent by a first proxy entity in the at least two proxy entities;
the master control entity selects a second proxy entity from other proxy entities except the first proxy entity in the at least two proxy entities according to the switching request or the reported measurement;
the main control entity sends a switching establishment request to the second proxy entity, and after receiving the response of the second proxy entity, the main control entity configures the first proxy entity to be switched to the second proxy entity.
