In the embodiment of the application, the wireless intelligent controller acquires the processing capacity and the load change condition of the wireless access network equipment through the capacity information and/or the wireless parameter list information of the wireless access network equipment, so that information subscription exceeding the processing capacity of the wireless access network equipment is avoided, and when the load of the wireless access network equipment is light and the processing capacity is strong, the wireless intelligent controller can acquire the change and timely adjust the message subscription strategy. In addition, the wireless intelligent controller can acquire the open function and the available parameter information of the wireless access network equipment, and avoid the completely invalid or partially invalid cell/user information subscription.

The following describes embodiments of the present application with an example of a radio access network device being E2Node (CU/DU/CU-CP/CU-DP, etc.).

E2Node reports E2Node capability information to wireless intelligent controller on E2 interface, so that wireless intelligent controller can better combine E2Node capability scheduling and control subscription information. The E2Node capability information can be transmitted when the E2 interface is established or after the establishment.

For example, after the E2 interface communication is established, the wireless intelligent controller initiates an inquiry request to the E2Node, and the E2Node replies an inquiry reply message to feed back the information of the self capability condition.

Or, when the E2 interface communication is established, the wireless intelligent controller carries the query indication in the E2 interface establishment request message, and the E2Node carries the self capability information in the interface establishment confirmation message.

Optionally, the E2Node capability information may include parameter information of multiple dimensions, such as the number of messages processed per second, interface bandwidth, memory size, and CPU occupancy, and the specific value or range of each parameter is carried in reporting. Capability level information of the E2Node may also be predefined, and a range of levels of a plurality of parameters may be defined in each capability level. Generally, the higher the parameter value, the higher the capability level value. If the highest capability level is 3, the number of the messages which can be transmitted and processed per second is more than 100 ten thousand per message; the lowest capability level is 1, and the number of messages which can be transmitted and processed per second is 1 ten thousand to 10 ten thousand. And by analogy, the value range of each other parameter is defined under each capability level.

The E2Node can feed back the interface capability condition according to the self running state. If the E2Node is in busy state, it can not process a lot of messages of E2 interface, then feeds back to the wireless intelligent controller, and can introduce newly defined status indication message or reuse the existing E2Node configuration update message to carry the E2Node capability information. The capability information may be an absolute value of each capability parameter, or may be a variation value of a certain capability parameter, and a capability parameter value without variation may not be transmitted. The capability information may include parameters such as busy status indication, the maximum number of messages that can be processed per second by the current E2Node, interface bandwidth, memory size, and CPU occupancy. After the wireless intelligent controller receives the message of inquiring the capability information of the E2Node, the sending quantity of the E2 interface message can be reduced according to the E2Node resource and the capability condition in the state indication message.

Optionally, the E2Node may periodically feed back the interface capability, and the period may be configured by the wireless intelligent controller or predetermined. The wireless intelligent controller can also send message query capability information, and the message indicates the E2Node to report state indication information or immediately feed back the E2Node capability information when the change of a certain index parameter exceeds a certain threshold or a low/high and a certain absolute value. The message may be sent either before or after the capability information is received. After the E2Node receives the message for inquiring the capability information, according to the trigger condition set in the message, the E2Node capability information is fed back when the capability parameter value meets the condition or immediately.

In addition, the message transmitted on the E2 interface can be compressed, and the data volume of the E2 interface is further reduced. The wireless intelligent controller determines whether to start and an adopted algorithm mechanism according to the current state of the E2Node and the compression algorithm supported by the wireless intelligent controller/E2 Node, and sends the decision to the E2Node, and after the E2Node confirms, the E2Node can start the compression algorithm to transmit the message of the E2 interface. The compression algorithm may be for the entire message of the E2 interface, or may compress some of the fields/information elements therein.

Optionally, the wireless intelligent controller further reduces the size of the content of the sent message of the E2 interface in the message request subscription. Only an objective function F (X1, X2, … Xn) and an input parameter set { X1, X2, … Xn } and/or an output parameter set target value { Y1, Y2, … Yn } and/or a subscription parameter set are sent in a subscription request message, an E2Node obtains a value of an output parameter set { Y1, Y2, … Yn } according to the objective function and the input parameter set after receiving the message, when the output parameter set meets the target value, message feedback is triggered, the subscription parameter set and/or the output parameter set are fed back at an E2 interface, and sending of intermediate redundant message content is omitted. It is also possible to send only the objective function F (X1, X2, … Xn) and the input parameter sets { X1, X2, … Xn } and/or the subscription parameter sets and/or the feedback periods and/or the number of feedbacks in the subscription request message, regularly feeding back the output parameter sets { Y1, Y2, … Yn } values and/or the subscription parameter sets over the feedback period time until the number of feedbacks is reached. If no feedback period is set or the number of times of feedback is set to 1, the output parameter set { Y1, Y2, … Yn } value and/or the subscription parameter set are fed back once at once.
