Description

Model identification method and device

Technical Field

The present application relates to the field of communication technology, and in particular to a model identification method and device.

Background technique

Machine learning models and/or artificial intelligence (AI) models are increasingly being used in wireless networks.

In order to facilitate the management and control of the model, a model identity (ID) can be set for each model, which may be a globally unique identifier. The model ID needs to be transmitted in model-related processes such as model selection, update, activation and deactivation. However, the globally unique model ID is not suitable for frequent transmission in wireless networks.

Summary of the invention

According to the first model identifier of the first model and the first mapping relationship, the second model identifier of the first model and/or the first model are determined.

In an embodiment of the present application, a first node determines a first mapping relationship and sends the first mapping relationship to a second node, so that the second node can determine the first model to be processed according to the first mapping relationship and perform relevant operations on the first model.

The model identification method and device provided by the present application are described in detail below in conjunction with the accompanying drawings.

Please refer to Figure 2, which is a flow chart of a model identification method provided in an embodiment of the present application. The method is executed by the first node, as shown in Figure 2, and the method may include but is not limited to the following steps:

S201, determining a first mapping relationship, wherein the first mapping relationship is used to enable the second node to determine a first model to be processed.

In the embodiments of the present application, the model may be a machine learning model, an AI model, or other models or modeled configurations. For example, the model may include AI models such as channel state information (CSI) compression, positioning, and beam management, which can be applied to various communication nodes involved in the present application, such as the first node, the second node, and the third node, and will not be described later.

In some implementations, the first mapping relationship may indicate:

a mapping relationship between a model and a first model identifier of the model; or,

A mapping relationship between a second model identifier of a type and a first model identifier;

The first model identifier may be a local model identifier of the model on the first node, and the second model identifier may be a global model identifier of the model, such as a globally unique model identifier of the model.

It is understandable that the first mapping relationship may include a mapping relationship between N models and the first model identifiers of the N models, where N is a positive integer greater than or equal to 1. The mapping relationship in the embodiment of the present application has the same meaning as the relationship, indicating that there is a relationship between the model and the first model of the model.

In some implementations, the first node may generate the first mapping relationship based on a protocol agreement or instruction.

In some other implementations, model configuration information may be obtained, and the first mapping relationship may be obtained from the model configuration information, that is, the first mapping relationship is carried in the model configuration information. It is understandable that the model configuration information may include relevant configurations of one or more models.

Optionally, the relevant configuration of each model may include a model and a first model identifier corresponding thereto, that is, the relevant configuration of the model includes the first mapping relationship of the model. Optionally, the relevant configuration of each model includes a first model identifier of the model and a second model identifier corresponding thereto, that is, the relevant configuration of the model includes the first mapping relationship of the model. It should be understood that the above is only an example, and the method of expressing the first mapping relationship is not limited thereto.

In the embodiment of the present application, the first model identifier and the second model identifier have at least one of the following characteristics:

The signaling overhead of the second model identifier is greater than that of the first model identifier;

The second model identifier requires a security protection mechanism, while the first model identifier does not require a security protection mechanism;

The transmission time identified by the first model is shorter than the transmission time identified by the second model;

The first model identifier is used to uniquely identify the model in the wireless access network, and the second model identifier is used to uniquely identify the model globally;

The first model identifier and the second model identifier are both used to determine the model.

It should be noted that there is a one-to-one correspondence between the model and the global model identifier, and a global identifier is used to uniquely identify a model. In the network node, each node can determine the global model identifier of the model by indication or pre-configuration. After determining the global model identifier, the network node can determine the model corresponding to the identifier.

It is understandable that in order to achieve the purpose of fast transmission model identifier, the first model identifier can be a short model identifier, that is, the number of bits occupied by the first model identifier is lower than the number of bits occupied by the second model identifier, thereby saving transmission resources and reducing signaling overhead.

In some implementations, the first model identifier is one of the following layer identifiers: a radio resource control (Radio Resource Control, RRC) layer identifier, a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer identifier, a radio link control (Radio Link Control, RLC) layer identifier, a media access control (Media Access Control, MAC) layer identifier, or a physical layer identifier.

S202: Send the first mapping relationship to the second node.

In an embodiment of the present application, the first node may send the first mapping relationship to the second node, and the second node may save the first mapping relationship after receiving the first mapping relationship.

Furthermore, the second node may determine the first model to be processed based on the first mapping relationship, and perform relevant operations on the first model.

In this disclosure, “based on,” “according to,” and “in consideration of” have the same meaning.

In the embodiment of the present application, the related operation may include at least one of the following operations: model selection, model update, model activation, model deactivation, model monitoring and model switching. This is only an example of the related operation and cannot be used as a condition to limit the present application.

In the embodiment of the present application, the first node and the second node may be selected from at least one of the following combinations:

The first node is the central unit gNB-CU (Central Unit, CU) of the base station, and the second node is the distributed unit gNB-DU (Distributed Unit, DU) of the base station;

The first node is the central unit control plane gNB-CU-CP (Central Unit Control Plane, CU-CP) of the base station, and the second node is the central unit user plane gNB-CU-UP (Central Unit User Plane, CU-UP) of the base station;

The first node is a source base station, and the second node is a destination base station;

The first node is a base station, and the second node is a user equipment UE;

The first node is a core network node, and the second node is a base station;

The first node is a core network node, and the second node is a UE.

In the example of the present application, the first node may determine the message used when transmitting the first mapping relationship between the first node and the second node according to the network element types of the first node and the second node.

In some implementations, the first node is a gNB-CU, the second node is a gNB-DU, and the first node may send the first mapping relationship to the second node via an F1 Application Protocol (F1AP) message.

In other implementations, the first node is gNB-CU-CP, the second node is gNB-CU-UP, and the first node may send the first mapping relationship to the second node via an E1 application protocol (E1AP) message.

In some further implementations, the first node is a source base station, the second node is a destination base station, and the first node may send the first mapping relationship to the second node via an Xn Application Protocol (XnAP) message.

In some other implementations, the first node is a base station, the second node is a user equipment (User Equipment, UE), and the first node sends the first mapping relationship to the second node through an RRC message or a user plane (User Plane, UP) message.

In some further implementations, the first node is a core network node, the second node is a base station, and the first node can send the first mapping relationship to the second node via an NG Application Protocol (NGAP) message.

In some further implementations, the first node is a core network node, the second node is a UE, and the first node may send the first mapping relationship to the second node via a non-access stratum (NAS) message.

Please refer to Figure 3, which is a flow chart of a method for identifying a model provided in an embodiment of the present application. The method is executed by a first node, as shown in Figure 3, and the method may include but is not limited to the following steps:

S301, determine a first mapping relationship, where the first mapping relationship is used to enable the second node to determine a first model that needs to be processed.

The first mapping relationship may indicate:

A mapping relationship between a model and a first model identifier of the model, or the first mapping relationship may be a mapping relationship between a second model identifier of the model and the first model identifier, wherein the first model identifier is a local model identifier of the model on the first node. The second model identifier is a global model identifier of the model, such as a globally unique model identifier of the model.

For a detailed description of step S301, please refer to the relevant contents in the above embodiment, which will not be repeated here.

S302: Send the first mapping relationship to the second node.

For a detailed description of step S302, please refer to the relevant contents in the above embodiment, which will not be repeated here.

S303: Send a first message to the second node, where the first message is a message related to the first model, and the first message includes a first model identifier of the first model.

In the embodiment of the present application, the first model is a model among the one or more models included in the first mapping relationship, and the first model is a model determined by the first node to be processed.

In an embodiment of the present application, the first node may send a first message to the second node, and the first message may be a message related to the first model, wherein the first message includes a first model identifier of the first model, and the first model is indicated to the second node through the first model identifier. Optionally, the first node determines the first model to be processed, and determines the first model identifier of the first model based on the first model and the first mapping relationship, and includes the first model identifier in the first message and sends it to the second node.

In some implementations, the first model identifier is one of the following layer identifiers: an RRC layer identifier, a PDCP layer identifier, an RLC layer identifier, a MAC layer identifier, or a physical layer identifier.

In the embodiment of the present application, the first node sends a first model identifier to the second node through a first message, and the first model identifier may be a layer identifier. Accordingly, the first node sends the first model identifier to the second node through at least one of the following signaling: RRC layer signaling, PDCP layer signaling, RLC layer signaling, MAC layer signaling, or physical layer signaling. That is, the first message may be at least one of the following signaling: RRC layer signaling, PDCP layer signaling, RLC layer signaling, MAC layer signaling, or physical layer signaling.

Optionally, the PDCP layer signaling may be a PDCP control protocol data unit (PDU); optionally, the RLC layer signaling may be an RLC control PDU.

Optionally, the MAC layer signaling may include at least one of the following messages:

Media Access Control-Control Element (MAC-CE), downlink control message (DCI), uplink control message (UCI), random access request, and random access feedback.

Optionally, the RRC layer signaling may be an RRC message.

It can be understood that the first message may also indicate to the second node one or more related operations that need to be performed on the first model.

After receiving the first message, the second node can determine the second model identifier or the first model corresponding to the first model identifier in the first message according to the first mapping relationship.

After determining the corresponding second model identifier, the identified model can be determined based on the second model identifier, and the model identified by the second model identifier is the first model. Optionally, the second node can determine one or more related operations that need to be performed on the first model based on the first message, and perform the one or more related operations on the first model.

In some embodiments, the first node is a base station, the second node is a UE, and the first message sent by the first node to the second node is RRC signaling, MAC signaling, or physical layer signaling sent by the base station to the UE. It can be understood that the RRC layer signaling can be an RRC message; the MAC layer signaling can include at least one of MAC-CE, DCI, UCI, random access request, and random access feedback.

In some implementations, the first mapping relationship and the first message may be sent together or separately. It is understandable that the first mapping relationship may be sent once and then sent again when the first mapping relationship is updated.

In the present application, by establishing a mapping between a model and a local model identifier of the model and transmitting the first mapping relationship to a second node, it is possible to transmit a local model identifier in a wireless network. The second node can also determine the purpose of the model it identifies based on the local model identifier, thereby eliminating the need to transmit the global model identifier of the model in the wireless network. This not only reduces the risk of tampering during transmission of the global model identifier and provides security for the model, but also reduces the transmission time and signaling overhead of the model identifier transmission.

The second node may send a second message to the first node, and the second message may be a message related to the first model, wherein the second message includes a first model identifier of the first model, and the first model is indicated to the first node through the first model identifier. Optionally, the second node determines the first model to be processed, and determines the first model identifier of the first model based on the first model and the first mapping relationship, and includes the first model identifier in the second message and sends it to the first node.
