Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a transmission method, apparatus, device, and readable storage medium. Background Art

[0002] The open and intelligent radio access network (O-RAN) was proposed by the O-RAN Alliance, which was established by China Mobile and other operators. Compared with the existing radio access network architecture and functions, O-RAN proposed a wireless intelligent controller.

[0003] See also Figure 1 , wireless intelligent controllers include: non-real-time wireless intelligent controllers and near-real-time wireless intelligent controllers. Among them, the near real-time wireless intelligent controller (near real-time RAN intelligence controller, Near-RT RIC) is divided into platform functions and instance application functions (xApp). Platform functions are used to support the deployment and operation of instance applications; instance application functions refer to xApps that solve a certain problem for a certain application scenario, such as load balancing, load prediction, video key quality indicators (Key Quality Indicators, KQI) prediction, quality of service (Quality of Service, QoS) and quality of experience (Quality of Experience, QoE) optimization, etc. The O-RAN Alliance defines the E2 interface on the near-real-time wireless intelligent controller and the base station side (such as the centralized unit (CU) / distributed unit (DU) / remote radio unit (RRU)). The near-real-time wireless intelligent controller obtains the data of the wireless side cell and user through the E2 interface for the data input of a certain xApp instance application, and obtains the strategy of a certain instance application through a series of algorithms and sends it to the base station side through the E2 interface. Currently, the E2 interface defines the message framework and clarifies the basic message flow of base station data collection and policy delivery.

[0222] According to the message compression mode, compression processing is performed on the message sent on the E2 interface, or compression processing is performed on a specific field or information element in the message sent on the E2 interface.

[0223] In an embodiment of the present application, the method further includes:

[0224] Receiving a subscription request message sent by the wireless intelligent controller, where the subscription request message is generated by the wireless intelligent controller according to capability information and / or wireless parameter list information of the wireless access network device;

[0225] According to the subscription request message, a message is sent to the wireless intelligent controller through the E2 interface.

[0226] In an embodiment of the present application, the subscription request message includes one or more of the following:

[0227] (1) Objective function;

[0228] (2) Input parameter set;

[0229] (3) Output parameter set target value;

[0230] (4) Subscription parameter set;

[0231] (5) Feedback cycle;

[0232] (6) Number of feedbacks.

[0233] In the embodiment of the present application, the wireless intelligent controller obtains the processing capacity and load change of the wireless access network device through the capability information and / or wireless parameter list information of the wireless access network device, and avoids the subscription of information that exceeds the processing capacity of the wireless access network device. When the load of the wireless access network device is light and the processing capacity is strong, the wireless intelligent controller can obtain the change and adjust the message subscription strategy in time. In addition, the wireless intelligent controller can obtain the open functions and parameter information of the wireless access network device, and avoid completely invalid or partially invalid cell / user information subscription.

[0234] The following describes an embodiment of the present application by taking the wireless access network device as E2 Node (CU / DU / CU-CP / CU-DP, etc.) as an example.

[0235] The E2 Node reports the E2 Node capability information to the wireless intelligent controller on the E2 interface so that the wireless intelligent controller can better schedule and control subscription messages in combination with the E2 Node capability. The E2 Node capability information can be transmitted when or after the E2 interface is established.

[0236] For example, after the E2 interface communication is established, the wireless intelligent controller initiates a query request to the E2 Node, and the E2 Node replies with a query reply message to feed back information about its own capability status.

[0237] Alternatively, when the E2 interface communication is established, the wireless intelligent controller may carry a query indication in an E2 interface establishment request message, and the E2 Node may carry its own capability information in an interface establishment confirmation message.

[0238] Optionally, the E2 Node 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 carry the specific value or range of each parameter when reporting. The capability level information of the E2Node can also be pre-defined, and the level range of multiple parameters is specified in each capability level. Generally, the higher the parameter value, the higher the capability level value. For example, if the highest capability level is 3, the corresponding number of messages that can be transmitted and processed per second is >1 million / messages; if the lowest capability level is 1, the corresponding number of messages that can be transmitted and processed per second is 10,000 / message to 100,000 / message. Similarly, the value range of each other parameter is defined at each capability level.

[0239] E2 Node can feedback the interface capability according to its own operation status. If E2 Node is in a busy state and cannot process a large number of messages of E2 interface, it will feedback to the wireless intelligent controller, and a newly defined status indication message can be introduced or the existing E2 Node configuration update message can be reused to carry E2 Node capability information. Capability information can be the absolute value of each capability parameter or the change value of a certain capability parameter. Capability parameter values ​​that have not changed may not be sent. Capability information may include parameters such as busy status indication, the maximum number of messages that the current E2 Node can process per second, interface bandwidth, memory size, and CPU occupancy. After receiving the message to query E2 Node capability information, the wireless intelligent controller can reduce the amount of E2 interface messages sent according to the E2Node resources and capabilities in the status indication message.

[0240] Optionally, the E2 Node may periodically feedback the interface capability status, and the period may be configured by the wireless intelligent controller or agreed in advance. The wireless intelligent controller may also send a message to query the capability information, and the message instructs the E2 Node to report a status indication message or immediately feedback the E2 Node capability information when a certain indicator parameter changes beyond a certain threshold or is lower / higher than a certain absolute value. The message may be sent before the capability information is fed back or after the capability information is received. After the E2 Node receives the message to query the capability information, it may feedback the E2 Node capability information immediately when the capability parameter value meets the condition according to the trigger condition set in the message.

[0241] In addition, the messages transmitted on the E2 interface can be compressed to further reduce the data volume of the E2 interface. The wireless intelligent controller decides whether to start the compression algorithm and the algorithm mechanism to be adopted based on the current state of the E2 Node and the compression algorithm supported by the wireless intelligent controller / E2 Node, and sends the decision to the E2 Node. After the E2 Node confirms, the compression algorithm can be started on the E2Node to transmit the message of the E2 interface. The compression algorithm can be for the entire message of the E2 interface, or it can be for compressing certain fields / information elements.

[0242] Optionally, the wireless intelligent controller further reduces the size of the message content sent by the E2 interface in the message subscription request. In the subscription request message, only the target function F (X1, X2, ...Xn) and the input parameter set {X1, X2, ...Xn} and / or the output parameter set target value {Y1, Y2, ...Yn} and / or the subscription parameter set are sent. After receiving the message, the E2 Node obtains the value of the output parameter set {Y1, Y2, ...Yn} according to the target function and the input parameter set. When the output parameter set meets the target value, the message feedback is triggered, and the subscription parameter set and / or the output parameter set are fed back on the E2 interface, thereby eliminating the sending of redundant message content in the middle. Alternatively, only the target function F (X1, X2, ...Xn) and the input parameter set {X1, X2, ...Xn} and / or the subscription parameter set and / or the feedback cycle and / or the number of feedback are sent in the subscription request message, and the output parameter set {Y1, Y2, ...Yn} value and / or the subscription parameter set are regularly fed back within the feedback cycle time until the number of feedback times is reached. If there is no feedback cycle setting or the number of feedbacks is set to 1, the output parameter set {Y1, Y2, ...Yn} values ​​and / or subscription parameter set are fed back immediately.
