Description

Algorithm updating method and device Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to an algorithm updating method, apparatus, device, and storage medium. Background Art

[0002] Artificial Intelligence (AI) is playing an increasingly important role in communication systems, and AI technology will become one of the core technologies of future communications. For example, there will be a lot of overlap between the sixth-generation mobile communication standard (6th Generation, 6G) and AI application scenarios. In this process, the diversity of AI algorithms and the use of AI algorithms can provide better services. Since each network element in the core network is responsible for its own tasks, it can provide corresponding services based on the stored AI algorithms. However, when the stored AI algorithms do not match the AI ​​network service tasks initiated by the terminal device, the corresponding AI network services cannot be provided, making the AI ​​network services less convenient.

[0074] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0075] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0076] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0077] The network elements or network functions involved in the embodiments of the present disclosure may be implemented by independent hardware devices or by software in the hardware devices, and this is not limited in the embodiments of the present disclosure.

[0078] With the development of mobile communications, AI will become one of the core technologies of future communications. 6G and AI have significant overlap in typical application scenarios, demonstrating a deep integration between the two. Furthermore, the large-scale coverage of 6G networks will provide a ubiquitous carrier space for AI, addressing the significant pain point of AI implementation, which is the lack of carriers and channels, significantly promoting the development and prosperity of the AI ​​industry.

[0079] While many automation measures have been implemented at various stages of the network to improve operational efficiency, the overall level of network autonomy is still relatively low, leaving significant room for improvement. Software-defined Networking (SDN) and Network Function Virtualization (NFV) architectures have enabled networks to achieve both high flexibility and increased complexity. For example, considerations for network resource allocation, transmission paths, and optimization algorithm design increase the number of factors involved, necessitating more intelligent approaches. AI technology can help networks achieve a higher level of autonomy, reducing costs and increasing efficiency. Due to the relatively recent application of AI technology in communications networks, most intelligent network applications involve optimizing and transforming traditional network architectures, resulting in a largely plug-in-style approach. Network AI functions are simply overlaid on existing network processes, and cross-domain and cross-layer intelligent applications face difficulties in achieving coordinated operation. Therefore, consideration is being given to integrating AI as an independent network function (NF) into the core network architecture, tightly coupled with other network elements to provide reliable and systematic AI service capabilities. This AI service function, referred to as AISF, is being considered.

[0080] In related technologies, updating AI algorithms is a key consideration. Because each core network element is responsible for its own tasks, storage and transmission capabilities are limited. Furthermore, to protect user privacy, large amounts of data need to be stored locally on the terminal device. The AISF's natively stored AI algorithms are insufficient to match any AI network service task initiated by the terminal device. The algorithm to be used must be determined based on the specific content provided when the task is initiated (including data and task description).

[0081] In addition, in related technologies, the Network Data Analytics Function (NWADF) in the 5th Generation Mobile Communication Technology System (5GS) only has the ability to make data analysis decisions. It is too macro, does not involve specific AI algorithms, and does not provide an AI algorithm update process, making it difficult to break down specific tasks.

[0082] An algorithm updating method, apparatus, device, and storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0083] FIG1 is a flow chart of an algorithm updating method provided by an embodiment of the present disclosure. The method is executed by a unified data management (UDM). As shown in FIG1 , the method may include the following steps:

[0084] Step 101: Receive an AI algorithm update query request sent by an artificial intelligence service function (AISF);

[0085] Step 102: In response to the AI ​​algorithm corresponding to the AI ​​algorithm update query request not existing in the UDM, a Nudm AI algorithm authentication update request Nudm_Algorithm_Update_Request is sent to the application function AF;

[0086] In one possible implementation, after receiving an AI algorithm update query request sent by an artificial intelligence service function (AISF), the UDM may determine whether the UDM contains an AI algorithm corresponding to the AI ​​algorithm update query request sent by the AISF. If the UDM does not contain an AI algorithm corresponding to the AI ​​algorithm update query request sent by the AISF, the UDM may send a Nudm AI algorithm authentication update request (Nudm_Algorithm_Update_Request) to the application function (AF). If the UDM contains an AI algorithm corresponding to the AI ​​algorithm update query request sent by the AISF, the UDM may directly return a Nudm_Algorithm_Update_Response to the NEF.

[0087] Step 103: Receive a Nudm AI algorithm authentication update response Nudm_Algorithm_Update_Response message sent by the AF, where the Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request;

[0088] In a possible implementation, the UDM receives a Nudm AI algorithm authentication update response Nudm_Algorithm_Update_Response message sent by the AF in response to the Nudm_Algorithm_Update_Request, wherein the Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request;.

[0089] Step 104: Send the AI ​​algorithm corresponding to the AI ​​algorithm update query request to the AISF.

[0090] In a possible implementation, the UDM obtains the AI ​​algorithm corresponding to the AI ​​algorithm update query request through the above steps, and may send the AI ​​algorithm to the AISF.

[0091] It should be noted that, in one embodiment of the present disclosure, a terminal device may refer to a device that provides voice and / or data connectivity to a user. The terminal device may communicate with one or more core networks via a radio access network (RAN). The terminal device may be an IoT terminal device, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an IoT terminal device. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a subscriber station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the terminal device may be a device of an unmanned aerial vehicle. Alternatively, the terminal device may be a vehicle-mounted device, for example, a vehicle-mounted computer with wireless communication capabilities, or a wireless terminal device connected to an external vehicle-mounted computer. Alternatively, the terminal device may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with wireless communication function.

[0092] In one embodiment of the present disclosure, an AI algorithm update query request refers to a request sent by the AISF to the UDM to query the AI ​​algorithm corresponding to the AI ​​service requirement determined by the AISF. Because the AI ​​algorithm corresponds to the AI ​​service requirement, when the AI ​​service requirement determined by the AISF changes, the AI ​​algorithm can also change accordingly.

[0093] And, in one embodiment of the present disclosure, FIG2 is an interactive diagram of an algorithm update method provided by an embodiment of the present disclosure. The UDM can receive an AI algorithm update query request sent by the AISF. When the UDM receives the AI ​​algorithm update query request sent by the AISF, the UDM can determine whether the UDM has an AI algorithm corresponding to the AI ​​algorithm update query request sent by the AISF. Specifically, the UDM can determine whether the network function (NF) has an AI algorithm corresponding to the AI ​​algorithm update query request sent by the AISF.

[0094] For example, in one embodiment of the present disclosure, in response to the UDM not having an AI algorithm corresponding to the AI ​​algorithm update query request sent by the artificial intelligence service function AISF, a Nudm AI algorithm authentication update request Nudm_Algorithm_Update_Request is sent to the application function AF. The UDM may include description information of the AI ​​algorithm and the identifier of the AI ​​algorithm in the Nudm_Algorithm_Update_Request. When the AF determines the AI ​​algorithm corresponding to the Nudm_Algorithm_Update_Request, it may send a Nudm AI algorithm authentication update response Nudm_Algorithm_Update_Response message to the UDM. The Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request. That is, the AF may provide the AI ​​algorithm corresponding to the AI ​​algorithm update query request to the UDM.

[0095] Furthermore, in one embodiment of the present disclosure, the AF may be any external third-party AF, and the AF may be an AF authorized by the UDM.

[0096] Furthermore, in one embodiment of the present disclosure, when the AF fails to determine the AI ​​algorithm corresponding to the Nudm_Algorithm_Update_Request request, the AF may send a response message to the UDM, wherein the response message includes indication information indicating the cause of the failure.

[0097] Furthermore, in one embodiment of the present disclosure, when the UDM obtains the AI ​​algorithm, it may send the AI ​​algorithm corresponding to the AI ​​algorithm update query request to the AISF in response to the AI ​​algorithm update query request.

[0098] And, in one embodiment of the present disclosure, the method further includes:

[0099] Send an authorization request for AF to the Network Exposure Function (NEF);

[0100] Receive authorization information sent by NEF in response to the authorization request.

[0101] And, in one embodiment of the present disclosure, the method further includes:

[0102] Receive the AI ​​session AISession registration request sent by the session management function SMF;

[0103] Send the contract information for the AISession registration request to the SMF, where the contract information includes the authorization information of the AI ​​session, the functions supported by the AI ​​session, and prohibited services.

[0104] In summary, in the disclosed embodiments, the UDM can receive an AI algorithm update query request sent by an artificial intelligence service function (AISF); in response to the AI ​​algorithm corresponding to the AI ​​algorithm update query request not existing in the UDM, send a Nudm AI algorithm authentication update request (Nudm_Algorithm_Update_Request) to the application function (AF); receive a Nudm AI algorithm authentication update response (Nudm_Algorithm_Update_Response) message sent by the AF, wherein the Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request; and send the AI ​​algorithm corresponding to the AI ​​algorithm update query request to the AISF. In the disclosed embodiments, if the AI ​​algorithm corresponding to the AI ​​algorithm update query request does not exist in the UDM, the AI ​​algorithm in the UDM can be updated so that the AI ​​algorithm corresponding to the AI ​​algorithm update query request exists in the UDM. The corresponding AI network service can be provided based on the AI ​​algorithm, thereby reducing the situation where the AI ​​network service cannot be provided when the AI ​​algorithm corresponding to the AI ​​algorithm update query request does not exist in the UDM. The present disclosure provides a processing method for an "algorithm update" scenario to update the AI ​​algorithm in the UDM. An algorithm update mechanism can be provided to update the AI ​​algorithm and provide corresponding AI network services based on the AI ​​algorithm, thereby improving the convenience of AI network services.

[0105] FIG3 is a flow chart of an algorithm updating method provided by an embodiment of the present disclosure. The method is executed by the UDM. As shown in FIG3 , the method may include the following steps:

[0106] Step 301: Receive an AI algorithm update query request sent by an artificial intelligence service function (AISF);

[0107] Step 302: In response to the AI ​​algorithm corresponding to the AI ​​algorithm update query request not existing in the UDM, an authorization request for the AF is sent to the network open function NEF;

[0108] Step 303: Receive authorization information sent by NEF in response to the authorization request;

[0109] Step 304: Send a Nudm AI algorithm authentication update request Nudm_Algorithm_Update_Request to the application function AF;

[0110] Step 305: Receive a Nudm AI algorithm authentication update response Nudm_Algorithm_Update_Response message sent by the AF, where the Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request;

[0111] Step 306: Send the AI ​​algorithm corresponding to the AI ​​algorithm update query request to the AISF.

[0112] It should be understood that the description of steps 301, 304, 304, 305 and 306 may correspond to steps 101, 102, 103 and 104, and will not be repeated here.

[0113] In addition, in one possible implementation of the present disclosure, the method may include:

[0114] Step 302: In response to the AI ​​algorithm corresponding to the AI ​​algorithm update query request not existing in the UDM, an authorization request for the AF is sent to the network open function NEF;

[0115] Step 303: Receive authorization information sent by NEF in response to the authorization request;

[0116] That is to say, when UDM determines that there is no AI algorithm corresponding to the AI ​​algorithm update query request, it can request an authorization request for AF from NEF. For example, UDM can authorize a certain AF to provide the corresponding AI algorithm and NEF authorizes the request to a third-party AF outside the core network architecture. NEF sends Nudm_Algorithm_Update_Request to request AF to provide the corresponding algorithm. The message may include, for example, the provided algorithm description and ID.

[0117] Among them, in one embodiment of the present disclosure, Figure 4 is an interactive diagram of a method for receiving authorization information provided by an embodiment of the present disclosure. In response to the fact that there is no AI algorithm corresponding to the AI ​​algorithm update query request sent by the artificial intelligence service function AISF in the UDM, the UDM may send an authorization request for the AF to the NEF. When the UDM receives the authorization information sent by the NEF in response to the authorization request, the UDM may authorize the AF corresponding to the authorization information to provide the AI ​​algorithm. The AI ​​algorithm may be an algorithm that does not exist in the UDM. That is, the UDM can update the AI ​​algorithm stored in the UDM. During this process, the NEF may perform information search and function query based on the authorization request for the AF to determine whether the UDM makes an AI algorithm request to the AF.

[0118] In summary, in the disclosed embodiment, an AI algorithm update query request is received from an artificial intelligence service function (AISF); in response to the AI ​​algorithm corresponding to the AI ​​algorithm update query request not existing in the UDM, an authorization request is sent to the network exposure function (NEF) for the AF; authorization information is received from the NEF in response to the authorization request; a Nudm AI algorithm authentication update request (Nudm_Algorithm_Update_Request) is sent to the application function (AF); a Nudm AI algorithm authentication update response (Nudm_Algorithm_Update_Response) message is received from the AF, wherein the Nudm_Algorithm_Update_Response message includes the AI ​​algorithm corresponding to the AI ​​algorithm update query request; and the AI ​​algorithm corresponding to the AI ​​algorithm update query request is sent to the AISF. In the disclosed embodiment, if the AI ​​algorithm corresponding to the AI ​​algorithm update query request is not present in the UDM, the AI ​​algorithm in the UDM can be updated so that the AI ​​algorithm corresponding to the AI ​​algorithm update query request exists in the UDM. Therefore, the corresponding AI network service can be provided based on the AI ​​algorithm, thereby reducing the situation where the AI ​​network service cannot be provided when the AI ​​algorithm corresponding to the AI ​​algorithm update query request is not present in the UDM. The embodiments of this disclosure specifically describe a scheme for authorization of the AF, and how the NEF can provide internal information search and function query. This disclosure provides a method for handling an "algorithm update" scenario to update the AI ​​algorithm in the UDM, and can provide an algorithm update mechanism to update the AI ​​algorithm and provide corresponding AI network services based on the AI ​​algorithm.

[0119] FIG5 is a flow chart of an algorithm updating method provided by an embodiment of the present disclosure. The method is executed by the UDM. As shown in FIG5 , the method may include the following steps:

[0120] Step 501: Receive an AI session AISession registration request sent by a session management function SMF;

[0121] Step 502: Send the contract information for the AISession registration request to the SMF, where the contract information includes the authorization information of the AI ​​session, the functions supported by the AI ​​session, and the prohibited services.

[0122] It should be understood that the above-mentioned embodiments of the present disclosure may be implemented individually or in combination with other embodiments of the present disclosure, and the present disclosure is not limited thereto.

[0123] In one embodiment of the present disclosure, FIG6 is an interactive diagram of an algorithm update method provided by an embodiment of the present disclosure. Before the UDM receives the AI ​​algorithm update query request sent by the AISF, the UDM may receive an AI session AISession registration request sent by the session management function SMF. The AISession registration request is used to establish an AISession.

[0124] Furthermore, in one embodiment of the present disclosure, the UDM may send contract information for an AISession registration request to the SMF. The contract information includes AI session authorization information, supported functions, and prohibited services. The functions supported by an AI session are not specific to a fixed function. For example, if the function name changes, the functions supported by the AI ​​session may also change accordingly.
