Description

Technical Field

[0002] Artificial Intelligence (AI) is a technology that enables intelligent machines to think and judge similarly to humans through large amounts of data and model training. Its research includes robotics, speech recognition, image recognition, natural language, and other fields. With the continuous integration of computing and communications, AI, as one of the future mainstream technologies of computers, is increasingly favored by the communications field.

[0118] First, the nouns involved in the embodiments of the present application are introduced:

[0119] 1. There are two understandings about AI sessions and Packet Data Unit (PDU) sessions: One understanding is that AI sessions are carried on PDU sessions. From the data plane perspective: terminal->RAN->UPF (PDU session here)->AI resource node. From the control plane perspective, when establishing an AI session, the AI ​​session establishment request can be placed in the N1 SM container, or a new container at the same level as the N1 SM container can be created and passed to the AMF, and then sent to the service management function to establish the AI ​​session. Another understanding is that AI sessions and PDU sessions are independent. From the user plane perspective, PDU sessions are terminal->RAN->UPF, and AI sessions are terminal->RAN->AI resource node. In this way, UPF and AI resource nodes can be co-located in terms of deployment. In the following embodiments, the solution based on the previous understanding is mainly described. AI service data is carried on the AI ​​session. The AI ​​session is a special session between the terminal and the AI ​​resource node. The AI ​​session uses the data radio bearer (DRB) of the PDU session for transmission, that is, the user plane data of the AI ​​session is transmitted to the AI ​​resource node for processing by using the transmission channel of the existing PDU session. The AI ​​session ID is used to identify the AI ​​session. It is allocated by the terminal and sent to the network when the AI ​​session is established. There is a many-to-one mapping relationship between the AI ​​session ID and the PDU session ID.

[0120] Optionally, in the case where the AI ​​session and the PDU session are independent, the establishment of the AI ​​session is similar to the establishment of a new PDU session, and the AI ​​session is a session that guarantees the QoS of the AI ​​service.

[0121] 2. In the following embodiments, AI service release is the most macroscopic concept; AI service release is divided into communication resource release and AI resource release; communication resource release is further divided into communication bearer release; AI resource release is further divided into AI bearer release.

[0122] It should be pointed out that, in order to distinguish different signaling, the AI ​​service resource release mentioned in Embodiments 3 / 4 / 5 can be understood as the release of AI service resources, including the release of communication resources and AI resources.

[0123] 3. Explanation of communication resources, AI resources, and business resources. Business resources are a collection of resources including communication resources, AI resources, policy resources, etc., and are a general term for various resources that provide reliable guarantee links for a certain service. Communication resources are a collection of resources provided by the existing 3GPP to terminals or third parties for communication services, including but not limited to communication links, allocated and scheduled frequency bands, memory of base stations or network elements, signaling forwarding scheduling time and other resources. AI resources are a collection of resources to ensure AI services, including but not limited to the computing power of high-performance computing machines (CPU / GPU, etc.), storage capacity for large amounts of training data, etc. Mapped to the actual link, it can be understood as a PDU session and an AI session. The former belongs to a session on the communication resource link, and the latter belongs to a session on the AI ​​resource link.

[0124] 4. Definitions of some network functions are shown in Table 1:

[0127]

[0128] It should be noted that the AI ​​business management function, AI model management function and AI resource management function can be the same network element and be jointly set up; or the AI ​​business management function and AI resource management function can be the same network element and be jointly set up.

[0129] The following is a detailed description of the AI ​​service release method provided in the embodiment of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0130] Please refer to Figure 2 The embodiment of the present application provides a method for releasing an AI service. The execution subject of the embodiment is a first device. The method for releasing an AI service includes:

[0131] Step 101: A first device receives a first release request message sent by a second device, where the first release request message is used to request the release of service resources associated with an artificial intelligence (AI) service.

[0132] Optionally, the second device is a terminal, or a network side device. The terminal is used to illustrate in the following example figure, and the terminal can be replaced by a network side device. The network side device includes at least one of the following: a policy charging function PCF, an access and mobility management function AMF, a session management function SMF, an application server, and NEF.

[0133] The first device may be a NAS interface function.

[0134] Specifically, the second device sends a first release request message to the first device, requesting the release of service resources corresponding to the AI ​​service, such as service resources (including communication resources and AI resources) established for the AI ​​service.

[0135] AI resources may refer to resources used for AI services, such as resources used for AI sessions, and communication resources may refer to resources used for PDU sessions.

[0136] Optionally, business resources include but are not limited to AI resources, communication resources, policy resources, etc.

[0137] Optionally, the AI ​​service release is triggered in at least one of the following cases:

[0138] When AI service ends, AF is triggered via PCF;

[0139] If the required quality of experience (QoE) cannot be met, PCF is triggered;

[0140] When the contract is changed or the contract becomes effective, UDM is triggered through AMF (NAS interface function) or SMF (communication management function);

[0141] During congestion control, SMF (communication management function) is triggered;

[0142] During congestion control, AMF (NAS interface function) is triggered;

[0143] The access network device (a form of base station) is triggered via AMF (NAS interface function) in at least one of the following situations: notification trigger when communication QoS cannot be met; congestion control;

[0144] The Over The Top (OTT) server is triggered by the 3GPP network when the AI ​​service ends. In this case, only AI resources are released, and no communication resources are released.

[0145] Step 102: The first device sends a first release response message to the second device, where the first release response message is used to indicate whether the service resources associated with the AI ​​service are successfully released;

[0146] Specifically, the first device sends a first release response message corresponding to the first release request message to the second device, so as to notify the second device whether the service resources associated with the AI ​​service are successfully released.

[0147] Step 103: The first device performs at least one of the following operations based on the first release request message:

[0148] Determine at least one of a third device, a fourth device, and a fifth device associated with the AI ​​service;

[0149] Sending a second release request message to a third device, where the second release request message is used to request the release of the AI ​​resources allocated for the AI ​​service;

[0150] Sending a third release request message to a fourth device, where the third release request message is used to request the release of communication resources allocated for the AI ​​service;

[0151] Send a fourth release request message to the third device, the fourth device or the fifth device, where the fourth release request message is used to request the third device, the fourth device or the fifth device to release the service resources associated with the AI ​​service.

[0152] Specifically, the third device is, for example, an AI service management function, the fourth device is, for example, a communication management function, and the fifth device is, for example, a policy billing function.

[0153] Specifically, the first device, as a device that directly interacts with the second device, is responsible for transmitting the first release request message of the second device at the request of different devices as control nodes. For example, the first device, as a control node, is responsible for controlling the release of resources, sending a second release request message to the third device to request the release of AI resources, and sending a third release request message to the fourth device to request the release of communication resources. Before sending the release request message, it is necessary to determine to which device the release request message needs to be sent, that is, to determine the associated AI service management function and communication management function;

[0154] When the first device does not act as a control node but only as a transmission node, and the third device, fourth device or fifth device acts as a control node, the first device needs to determine which device to send the release request message to, that is, determine at least one of the associated third device, fourth device and fifth device; the first device sends a fourth release request message to the third device, fourth device or fifth device, requesting the third device, fourth device or fifth device to release the service resources associated with the AI ​​service, that is, the third device, fourth device or fifth device controls the release of resources.

[0155] It should be noted that if both "sending a second release request message to the third device" and "sending a third release request message to the fourth device" need to be executed, there is no necessary order for the two messages. The "sending a second release request message to the third device" can be executed first, and then the "sending a third release request message to the fourth device" can be executed, or the "sending a third release request message to the fourth device" can be executed first, and then the "sending a second release request message to the third device" can be executed; or, the "sending a second release request message to the third device" and the "sending a third release request message to the fourth device" can also be executed in parallel; the order of release and serial or parallel execution are determined by the first device.

[0156] In the method of this embodiment, the first device receives a first release request message sent by the second device, which is used to request the release of business resources associated with the AI ​​service; the first device sends a first release response message to the second device, which is used to indicate whether the business resources associated with the AI ​​service are successfully released; the first device performs at least one of the following operations based on the first release request message: determines at least one of the third device, the fourth device and the fifth device associated with the AI ​​service; sends a second release request message to the third device, which is used to request the release of AI resources allocated for the AI ​​service; sends a third release request message to the fourth device, which is used to request the release of communication resources allocated for the AI ​​service; sends a fourth release request message to the third device, the fourth device or the fifth device, which is used to request the release of business resources associated with the AI ​​service, thereby realizing the release process of the AI ​​service, having greater flexibility, and being able to help dynamically recycle resources to meet the resource requirements of a large number of AI services.

[0157] Optionally, the first release request message includes at least one of the following:

[0158] Release requester identification, AI service information, packet data unit PDU session information, AI session information, policy information, network identification information, release reason, release type.

[0159] Among them, when the second device (terminal or NF) is a terminal, the release requester identifier is a terminal identifier, such as a subscription permanent identifier (SUPI), a globally unique temporary UE identity (GUTI), etc.; when the second device is any network element in the aforementioned network side device, the release requester identifier is a network device identifier, such as NF ID, network element address, etc. Optionally, the second release request message includes at least one of the following: release requester identifier, AI service information, PDU session information, AI session information, AI service management function address, policy information, release reason;

[0160] The third release request message includes at least one of the following: release requester identification, AI service information, PDU session information, AI session information, network identification information, communication management function address, policy information, and release reason.

[0161] Optionally, the fourth release request message includes at least one parameter in the first release request message.

[0162] Optionally, the release requester identifier includes at least one of the following: a terminal identifier, a network device identifier;

[0163] The AI ​​service information includes at least one of the following: an AI service identifier, an AI service description, a model contract association identifier, and a model identifier;

[0164] The PDU session information includes at least one of the following: a PDU session identifier, a PDU session type, a communication resource identifier, and a communication resource node address;

[0165] The AI ​​session information includes at least one of the following: an AI session identifier, an AI session type, an AI resource identifier, and an AI resource node address;

[0166] The network identification information includes at least one of the following: a slice identification, a data network name DNN;

[0167] The policy information includes at least one of the following: an AI policy identifier, a communication policy identifier, a comprehensive policy identifier, and a policy charging function address;

[0168] The release reason includes at least one of the following: normal release, temporary release, and release due to business resource switching.

[0169] Among them, the model contract association identifier in the AI ​​service information is also called model correlation ID, which is an identifier assigned by the model management unit and has a contract or association relationship with a certain model, which can be understood as a subscription ID; the model identifier is a globally unique or locally unique identifier ID assigned by the model management unit to a certain model, with which a unique model can be found in 3GPP or PLMN; the AI ​​service identifier is used to indicate what kind of AI service this is, such as image recognition, speech recognition, environment reconstruction, etc., and can be expressed in a string of standardized IDs; the AI ​​service description indicates the type of AI service, such as reasoning service, training service, training service and reasoning service;

[0170] In one implementation, the PDU session type is used to indicate that the current PDU session is associated with an AI session, and is distinguished from PDU sessions related to some non-AI services.

[0171] In one implementation, the AI ​​session type is used to characterize a released AI session;

[0172] The comprehensive strategy identifier is, for example, an identifier of a comprehensive strategy including AI and communication.

[0173] The release reason is used to indicate the type of AI service resource release, including normal release, release due to switching, temporary release, etc.

[0174] Optionally, the release type includes, for example, at least one of the following: releasing only communication resources; releasing only AI resources; releasing all resources.

[0175] Exemplarily, the second device, for example, receives a release request message including a release requester identifier, and can determine the device that needs to release the AI ​​service based on the release requester identifier, and release the AI ​​service associated with the device corresponding to the release requester identifier, that is, release the service resources managed by the AI ​​service. For example, the second device receives a release request message including AI service information, and can determine the AI ​​service to be released based on the AI ​​service information, and then initiate the release process. For example, the second device receives a release request message including PDU session information, and can determine the AI ​​service associated with the PDU session information based on the PDU session information, and then initiate the release process. For example, the second device receives a release request message including policy information, and can determine the AI ​​service associated with the policy information based on the policy information, such as the AI ​​service to which the policy information applies, and then initiate the release process. For example, the second device receives a release request message including a release reason, and the release reason is, for example, temporary release, then the service resources of the AI ​​service are released, for example, after the corresponding resources or bearer are released, the locally stored context will be retained. For example, the second device receives a release request message including a release type, and the release type is, for example, only AI resources are released, then the AI ​​resources of the AI ​​service are released.

[0176] Optionally, the release request message implementation method includes at least one of the following:

[0177] A new message is added to release sessions / resources / bearers related to AI services. The released AI service-related resources include communication resources and AI resources.

[0178] For the existing PDU session release request, the PDU session type needs to be set to "AI session" and the AI ​​session type needs to be set to "Release AI session" in the release request message to instruct the network to release the PDU session and the associated AI session.

[0179] It should be noted that for the temporary release in the release reason, in subsequent operations, when the network element releases the corresponding resources or bearers, the locally stored context will be retained, and the resource configuration and bearer configuration can be referenced or reused when the same AI service is established subsequently; if it is a non-temporary release (including normal release, release due to switching, etc.), the locally retained context will be directly deleted, and it will need to be re-established when the same AI service is established subsequently.

[0180] It should be noted that there are two ways to understand the relationship between AI sessions and PDU sessions. One is that AI sessions are carried on PDU sessions, and the other is that AI sessions and PDU sessions are independent of each other. The former, that is, when the data plane transmits AI service data, the AI ​​data is carried on the data plane resources from UE to UPF. The two are tightly coupled when they are established and released. The PDU session type can be set to "AI session" (here it is understood as a PDU session attribute, and the PDU session is associated with the AI ​​session), and the AI ​​session type is set to "Release AI session" to release resources (first, the PDU session type is associated with the AI ​​session, which is different from some PDU sessions that currently only support communication. Secondly, the AI ​​session type indicates a release operation, so that the recipient can understand that the AI-related resources are released, and further understand that: only when the PDU session type indicates an AI session, will the AI ​​session type be further carried to indicate an establishment operation, a modification operation, or a release operation.). The release of the latter should be independent of each other, that is, when the release request message only contains AI session information, the network side executes the release of AI resources, and when the request message only contains PDU session information, the network side executes the release of communication resources. The two are decoupled from each other and do not need to be released in the same message. Of course, the latter still requests the network side to release in one request message at the same time.

[0181] In addition, the NAS interface function can be understood as AMF.

[0182] The following are several ways to implement "partial release":

[0183] Implementation 1:

[0184] If the release request message only contains AI service information, but does not contain AI session information and PDU session information, the NAS interface function can find the AI ​​session and PDU session information associated with the AI ​​service, and both "sending a second release request message to the third device" and "sending a third release request message to the fourth device" need to be executed; if the release request message only contains AI session information, the NAS interface function only needs to send the second release request message to release the associated AI resources; if the release request message only contains PDU session information, the NAS interface function only needs to send the third release request message to release the associated communication resources.

[0185] Implementation 2:

[0186] When the release type is to release only AI resources, only "sending a second release request message to the third device" and subsequent related steps are executed, and "sending a third release request message to the fourth device" and subsequent related steps are not executed, and only the content related to AI resources is released, including AI bearer and AI policy; when the release type is to release only communication resources, only "sending a third release request message to the fourth device" and related steps are executed, and "the third device sends a second release request message" and subsequent related steps are not executed, and only the content related to communication resources is released, including communication bearer and communication policy; when the release type is to release all resources, subsequent steps are executed normally to release AI resources and communication resources.

[0187] It should be noted that the above-mentioned partial release (including only releasing AI resources and only releasing communication resources) includes the situation that one PDU session can support the service flows of multiple AI sessions, that is, there are multiple QoS flows in the PDU session, which can support multiple different AI services. One AI service is carried out on one AI session. When an AI service ends, the PDU session can release / modify the corresponding QoS flow, and the AI ​​session carried on it is also released, which is the partial release here. At this time, the communication resources are not released, only the AI ​​resources are released.

[0188] Optionally, in the case where the first release response message is used to indicate the failure to release the service resources associated with the AI ​​service, the first release response message includes a first cause value, and the first cause value includes at least one of the following: the AI ​​service does not exist, the AI ​​service is in use and cannot be released, the communication resource release fails, and the AI ​​resource release fails.

[0189] Specifically, if the first device does not find the associated communication management function and AI service management function, or the current network does not support the AI ​​service information requested by the second device, it directly sends a first release response message to reject the request of the second device, indicating that the resources associated with the requested AI service cannot be released. The first reason value includes: AI service resources do not exist, AI session does not exist, communication resources do not exist, and AI service does not exist.

[0190] Optionally, the method further comprises:

[0191] The first device receives a second release response message sent by the third device, which is used to indicate whether the AI ​​resource is successfully released;

[0192] In the case where the second release response message is used to indicate a failure to release the AI ​​resource, the second release response includes a second cause value; the second cause value includes at least one of the following: the AI ​​resource does not exist, and the AI ​​resource is in use and cannot be released.

[0193] Optionally, when the second release response message is used to indicate a successful release, the first device sends a third release request message to the fourth device to further release communication resources; otherwise, the first device directly replies to the first release response message and indicates a release failure.

[0194] Optionally, the method further comprises:

[0195] The first device receives a third release response message sent by the fourth device, which is used to indicate whether the communication resource is successfully released;

[0196] In the case where the third release response message is used to indicate a failure in releasing communication resources, the third release response message includes a third cause value, and the third cause value includes at least one of the following: the communication resource does not exist, and the communication resource is in use and cannot be released.

[0197] Optionally, the method further comprises:

[0198] The first device receives a fourth release response message sent by the third device, the fourth device or the fifth device, which is used to indicate whether the service resources associated with the AI ​​service are successfully released;

[0199] In the case where the fourth release response message is used to indicate a failure to release service resources, the fourth release response message includes a fourth cause value, and the fourth cause value includes at least one of the following: the AI ​​service does not exist, the communication resource release fails, the AI ​​resource release fails, and the AI ​​service is in use and cannot be released.

[0200] Optionally, the protocol stack of the second device includes at least one of the following: an AI management layer, non-access layer session management NAS-SM and non-access layer message management NAS-MM; the AI ​​management layer is used to generate messages related to releasing AI resources, and the NAS-SM is used to generate messages related to releasing communication resources.

[0201] Specifically, a message related to releasing AI resources can be generated through a newly added AI management layer. The AI ​​management layer can be set below, above, or within the NAS-SM, which is not limited in the embodiments of the present application.

[0202] In the above implementation, the protocol stack is implemented in various ways with great flexibility.

[0203] For example, Figure 3 As shown, a new protocol layer, such as an AI management layer, is responsible for generating AI service messages, such as an AI service establishment message and an AI service release message, which are used to trigger the allocation and release of AI resources.

[0204] Message encapsulation mode: NAS message (communication resource release message, AI resource release message) (communication resource release message and AI resource release message are in a parallel relationship);

[0205] That is, the message encapsulation method is to use the NAS message to carry the message related to releasing the AI ​​resource (for example, releasing the AI ​​resource message), and / or to carry the message related to releasing the communication resource (for example, releasing the communication resource message);

[0206] The NAS-SM layer generates a communication resource release message, the AI ​​management layer generates an AI resource release message, and the NAS interface function determines whether to execute serially or in parallel, and the order of forwarding the communication resource release request message and the AI ​​resource release request message in serial.

[0207] For example, Figure 4 As shown, the terminal triggers, which is controlled by the NAS interface function, and the AI ​​resources and communication resources are released serially. In this embodiment, Figure 3 The protocol architecture shown, the method includes:

[0208] Step 1: The terminal sends an AI service release request message to the NAS interface function;

[0209] Step 2: The NAS interface function releases communication and AI resources;

[0210] Step 3: The NAS interface function sends an AI resource release request message a to the AI ​​service management function;

[0211] Step 4: The AI ​​service management function sends a release AI policy request message to the policy charging function;

[0212] Step 5: The AI ​​service management function sends a model release request message to the AI ​​model management function;

[0213] Step 6: The AI ​​service management function sends an AI resource release request message b to the AI ​​resource management function;

[0214] Step 7: The AI ​​resource management function sends a request to release the AI ​​bearer to the AI ​​resource node;

[0215] Step 8: The AI ​​resource management function sends an AI resource release response message b to the AI ​​service management function;

[0216] Step 9: The AI ​​service management function sends an AI resource release response message a to the NAS interface function;

[0217] Step 10: The NAS interface function sends a communication resource release request to the communication management function;

[0218] Step 11: The communication management function sends a communication policy release request to the policy charging function;

[0219] Step 12: The communication management function sends a communication bearer release request to the communication resource node;

[0220] Step 13: The communication management function sends a communication resource release response to the NAS interface function;

[0221] Step 14: The NAS interface function sends an AI service release response message to the terminal.

[0222] Optionally, the fourth device sends a release request message to a ninth device (such as a communication resource node) to request the release of the communication bearer allocated for the AI ​​service, and the release request message includes at least one of the following: a communication resource node address, PDU session information, and AI service information.

[0223] Optionally, the fourth device receives a release response message sent by the ninth device, which is used to indicate whether the communication bearer is successfully released;

[0224] In the case where the release response message is used to indicate a failure in releasing the communication bearer, the release response message includes a cause value, for example, at least one of the following: the communication bearer does not exist, and the communication bearer is in use and cannot be released.

[0225] It should be noted that step 4 is optional. If no policy billing function assigns an AI policy to an AI service session when it is established, and it is locally configured by the AI ​​management function, then in this embodiment, when the AI ​​policy is released, the AI ​​service management function locally releases the corresponding AI policy from the policy context associated with the terminal.

[0226] It should be noted that step 11 is optional. If no policy billing function assigns a communication policy to the AI ​​service session when it is established, and it is locally configured by the communication management function, then in this embodiment, when the communication policy is released, the communication management function locally releases the corresponding communication policy from the policy context associated with the UE.

[0227] Optionally, the AI ​​policy release request in step 4 may be to dissolve the association, or to delete the AI ​​policy associated with the AI ​​service, which is not limited in this embodiment of the present application.

[0228] Optionally, the communication policy release request in step 11 may be to dissolve the association, or to delete the communication policy associated with the AI ​​service, which is not limited in this embodiment of the present application.

[0229] Optionally, the AI ​​service management function sends a model release request message to the AI ​​model management function to release the association status between the model and the AI ​​service, or to release the association status between the model and the user. The model release message includes at least one item: release requester identifier, AI service identifier, AI service description, model contract association identifier, model identifier, and AI model management function address;

[0230] It should be noted that the model release here does not mean requesting the AI ​​model management function to completely delete a model. The release here is the change in the association state triggered by the termination of the AI ​​service, that is, the terminal or the AI ​​service is no longer a consumer of the model, which is a change in the binding relationship (disassociation). When a new AI service is triggered later, a model may be re-bound, or the same model may be bound.

[0231] This step is optional and needs to be performed when at least one of the following conditions is met:

[0232] AI business information includes model identifiers, such as model ID, etc.

[0233] The AI ​​business information includes a model contract correlation identifier, such as a model correlation ID.

[0234] The AI ​​service information may be the AI ​​service information included in the model release request message.

[0235] Optionally, the AI ​​model management function sends a model release response message to the AI ​​business management function to reply whether the model associated with the AI ​​business is successfully released.

[0236] Optionally, in step 6, the AI ​​service management function sends an AI resource release request message b to the AI ​​resource management function, requesting the release of AI resources established for the AI ​​service, including computing resources, storage resources and AI link resources (i.e., AI bearers) reserved for the AI ​​service.

[0237] The AI ​​resource release request message b includes at least one of the following: an AI resource management function address, AI session information, and AI service information.

[0238] For example, Figure 5 As shown, the terminal triggers, which is controlled by the NAS interface function, and AI resources and communication resources are released in parallel. Figure 3 The protocol stack shown, wherein the NAS interface function forwards the release communication resource message and the release AI resource message in parallel. The method comprises:

[0239] Step 1: The terminal sends an AI service release request message to the NAS interface function;

[0240] Step 2: The NAS interface function releases communication and AI resources;

[0241] Step 3a, the NAS interface function sends a communication resource release request message to the communication management function;

[0242] Step 3b: The NAS interface function sends an AI resource release request message a to the AI ​​service management function;

[0243] Step 4a, the communication management function sends a release communication policy request to the policy charging function;

[0244] Step 4b: The AI ​​service management function sends a request to release the AI ​​policy to the policy charging function;

[0245] Step 5: The AI ​​business management function sends a model release request to the AI ​​model management function;

[0246] Step 6: The communication management function sends a communication bearer release request to the communication resource node;

[0247] Step 7: The communication management function sends a communication resource release response message to the NAS interface function;

[0248] Step 8: The AI ​​service management function sends an AI resource release request message b to the AI ​​resource management function;

[0249] Step 9: The AI ​​resource management function sends a request to release the AI ​​bearer to the AI ​​resource node;

[0250] Step 10: The AI ​​resource management function sends an AI resource release response message b to the AI ​​service management function;

[0251] Step 11: The AI ​​service management function sends a resource release status notification message to the communication management function;

[0252] Step 12: The AI ​​service management function sends an AI resource release response message a to the NAS interface function;

[0253] Step 13: The NAS interface function sends an AI service release response message to the terminal.

[0254] Specifically, this embodiment and Figure 4 The difference between the embodiments shown is that the NAS interface function initiates the release of communication resources and the release of AI resources, which are parallel operations, while Figure 4 The embodiment shown is a serial operation (there is no mandatory requirement for the order of initiating the communication resource release and the AI ​​resource release);

[0255] Steps 3a, 4a, 6 and 7 belong to the release process of communication resources; steps 3b, 4b, 5, 8-10 and 12 belong to the release process of AI resources; the specific process can refer to the similar description in the above embodiment. This process supports releasing only AI resources or only communication resources.

[0256] Optionally, the embodiment includes step 11, in which the message is a status notification message, sent between the AI ​​service management function and the communication management function, Figure 5 In the example, the AI ​​service management function sends the message to the communication management function, but in the same way, the communication management function can send the message to the AI ​​service management function. The status notification message is used to notify the status of resource release. Figure 5 In the case shown, when the AI ​​service management function fails to release the AI ​​resources, it notifies the communication management function that the communication resources associated with the current AI service need to be maintained and not released.

[0257] Optionally, the status notification message includes at least one of the following:

[0258] Release requester identifier, AI service management function address, communication management function address, PDU session information, AI session information, AI service information, status indication, and failure reason;

[0259] The status indication is used to indicate whether the AI ​​resources or communication resources of the AI ​​service are successfully released.

[0260] Among them, the status indication indicates the release of AI resources or communication resources, including release success, release failure, release blocking, etc.;

[0261] Failure reasons include: AI resources do not exist, communication resources do not exist, resources are in use and cannot be released, etc.

[0262] For example, after receiving the resource release status notification message (this message may occur before or after step 6), if the communication resources have been released (step 6 has occurred), the communication management function re-establishes the communication resources managed by the AI ​​service; otherwise (step 6 has not occurred), there is no need to execute step 6, and the release failure is directly indicated in the response message of step 7, and the reason value is consistent with the reason value of the received resource release status notification.

[0263] Alternatively, if Figure 6 As shown in the figure, a new protocol layer, such as the AI ​​management layer, is added. The new protocol layer is below the existing NAS-SM layer.

[0264] The message encapsulation method is: NAS message (release AI resource message (release communication resource message));

[0265] That is, the message encapsulation method is to use a NAS message to carry the message related to releasing the AI ​​resource, and the message related to releasing the AI ​​resource includes the message related to releasing the communication resource;

[0266] The NAS-SM layer is used to generate messages related to releasing communication resources, and the AI ​​management layer is used to generate messages related to releasing AI resources.

[0267] like Figure 7 As shown, Figure 6 The difference between the protocol stack is that the AI ​​service management function generates a communication resource release message and sends it to the communication management function (interaction between network elements).

[0268] The message encapsulation method is: NAS message (AI resource release message);

[0269] That is, the message encapsulation method is to use NAS messages to carry messages related to the release of AI resources, and communication resource release is initiated by default.

[0270] The AI ​​service management function generates a communication resource release message, and the AI ​​management layer of the terminal or network device generates an AI resource release message.

[0271] For example, Figure 8 As shown, the terminal is triggered and controlled by the AI ​​service management function to serially release AI resources and communication resources. Figure 6 and Figure 7 The protocol stack shown in the figure, at this time, the second device and the NAS interface function do not act as a control node, and only forward the AI ​​service release request message of the terminal or network device, and the method includes:

[0272] Step 1: The terminal sends an AI service release request message to the NAS interface function;

[0273] Step 2: The NAS interface function sends an AI service resource release request to the AI ​​service management function;

[0274] Step 3: The AI ​​service management function sends at least one of the release communication policy and the AI ​​policy to the policy charging function;

[0275] Step 4: The AI ​​business management function sends a model release request to the AI ​​model management function;

[0276] Step 5: The AI ​​service management function sends an AI resource release request message to the AI ​​resource management function;

[0277] Step 6: The AI ​​resource management function sends a request to release the AI ​​bearer to the AI ​​resource node;

[0278] Step 7: The AI ​​resource management function sends an AI resource release response message to the AI ​​service management function;

[0279] Step 8: The AI ​​service management function sends a communication resource release request message to the communication management function;

[0280] Step 9: The communication management function sends a communication bearer release request to the communication resource node;

[0281] Step 10: The communication management function sends a communication resource release response message to the AI ​​service management function;

[0282] Step 11: The AI ​​service management function sends an AI service resource release response message to the NAS interface function;

[0283] Step 12: The NAS interface function sends an AI service release response message to the terminal.

[0284] Specifically, this embodiment and Figure 4 The differences between the shown embodiments are:

[0285] 1) After receiving the AI ​​service release request message sent by the terminal, the NAS interface function first executes step 2 to send an AI service resource release request message to the AI ​​service management function, and the AI ​​service management function is responsible for the resource release task;

[0286] 2) After the AI ​​service management function successfully releases the AI ​​resources, it sends a message to the communication management function to release the communication session; of course, the AI ​​service management function can decide whether to execute steps 4-7 or steps 8-10 first, either in either order. Only when one party successfully releases will the release of the other party be triggered, otherwise the AI ​​service resource release response message will be directly replied to indicate that the release failed. If both parties successfully release, the AI ​​service resource release response message indicates that the release is successful.

[0287] 3) If the release type is carried in step 1 and it indicates that only communication resources are to be released, the specified communication resources are released, for example, the AI ​​service management function sends a request message for releasing communication resources to the communication resource management function; or, if it indicates that all resource session information is to be released, all resources are released, for example, the AI ​​service management function sends a request message for releasing communication resources to the communication resource management function, and the AI ​​service management function sends a request message for releasing AI resources to the AI ​​resource management function.

[0288] Alternatively, if Fig. 9 As shown, a new protocol layer, such as an AI management layer, is responsible for generating AI service messages, such as an AI service establishment message and an AI service release message, which are used to trigger the allocation and release of AI resources.

[0289] Message encapsulation mode: NAS message (communication resource release message (AI resource release message));

[0290] The message encapsulation method is to use a NAS message to carry the message related to releasing the communication resources, and the message related to releasing the communication resources includes a message related to releasing the AI ​​resources;

[0291] The NAS-SM layer generates a communication resource release message, and the AI ​​management layer generates an AI resource release message.

[0292] like Fig.10 As shown, the NAS-SM layer is enhanced. When the NAS-SM generates a release communication resource message, the message includes the AI ​​service description information, which is used to instruct the network to release the AI ​​resources.

[0293] Message encapsulation method: NAS message (communication resource release message [AI service description information]).

[0294] The message encapsulation method is to use a NAS message to carry the message related to releasing communication resources, and the message related to releasing communication resources includes AI service description information.

[0295] For example, Fig.11 As shown, the terminal triggers and is controlled by the communication management function to serially release AI resources and communication resources. At this time, the second device and the NAS interface function do not serve as control nodes, but only forward the AI ​​service release request message of the terminal or network device. The following can be used Figure 6 and Figure 7 The protocol stack shown, the method comprises:

[0296] Step 1: The terminal sends an AI service release request message to the NAS interface function;

[0297] Step 2: The NAS interface function sends an AI service resource release request to the communication management function;

[0298] Step 3: The communication management function sends at least one of the released communication policy and the AI ​​policy to the policy charging function;

[0299] Step 4: The communication management function sends a communication bearer release request to the communication resource node;

[0300] Step 5: The communication management function sends an AI resource release request message a to the AI ​​service management function.

[0301] Step 6: The AI ​​business management function sends a model release request to the AI ​​model management function.

[0302] Step 7: The AI ​​service management function sends an AI resource release request message b to the AI ​​resource management function.

[0303] Step 8: The AI ​​resource management function sends a request to release the AI ​​bearer to the AI ​​resource node;

[0304] Step 9: The AI ​​resource management function sends an AI resource release response message b to the AI ​​service management function;

[0305] Step 10: The AI ​​service management function sends an AI resource release response message a to the NAS interface function;

[0306] Step 11: The communication management function sends an AI service resource release response message to the NAS interface function.

[0307] Step 12: The NAS interface function sends an AI service release response message to the terminal.

[0308] Specifically, this embodiment and Figure 4 The differences between the shown embodiments are:

[0309] 1) After receiving the AI ​​service release request message sent by the terminal, the NAS interface function first executes step 2 and sends an AI service resource release message to the communication management function, which is responsible for the resource release task;

[0310] 2) After successfully releasing the communication resources, the communication management function sends a message to the AI ​​service management function to release the AI ​​resources; of course, the communication management function can decide to execute 4 or 5-10 first, either order. Only when one party successfully releases will the release of the other party be triggered, otherwise it will directly reply with an AI service resource release response message to indicate that the release failed. If both parties successfully release, the AI ​​service resource release response message indicates that the release is successful.

[0311] 3) If the release type is carried in step 1 and it is indicated that only AI resources are released, the specified AI session information is released or all resources are released. For example, the communication management function sends an AI resource release request message to the AI ​​service management function; or, if it is indicated that all resources are released, all resources are released, the communication management function sends an AI resource release request message to the AI ​​service management function, and the communication management function sends a communication bearer release request message to the communication resource node.

[0312] For example, Fig.12 As shown, the terminal is triggered and controlled by the policy charging function, and the AI ​​resources and communication resources are released serially. At this time, the second device and the NAS interface function do not serve as control nodes, but only forward the AI ​​service release request message of the terminal or network device. The method includes:

[0313] Step 1: The terminal sends an AI service release request message to the NAS interface function;

[0314] Step 2: The NAS interface function sends an AI service resource release request to the policy charging function;

[0315] Step 3: The policy charging function sends an AI resource release request message a to the AI ​​service management function.

[0316] Step 4: The AI ​​business management function sends a model release request to the AI ​​model management function.

[0317] Step 5: The AI ​​service management function sends an AI resource release request message b to the AI ​​resource management function.

[0318] Step 6: The AI ​​resource management function sends a request to release the AI ​​bearer to the AI ​​resource node;

[0319] Step 7: The AI ​​resource management function sends an AI resource release response message b to the AI ​​service management function;

[0320] Step 8: The AI ​​service management function sends an AI resource release response message a to the NAS interface function;

[0321] Step 9: The policy charging function sends a communication resource release request to the communication management function;

[0322] Step 10: The communication management function sends a communication bearer release request to the communication resource node;

[0323] Step 11: The communication management function sends a communication resource release response to the policy charging function;

[0324] Step 12: The policy charging function releases at least one of the communication policy and the AI ​​policy;

[0325] Step 13: The policy charging function sends an AI service resource release response message to the NAS interface function.

[0326] Step 14: The NAS interface function sends an AI service release response message to the terminal.

[0327] Specifically, this embodiment and Figure 4 The differences between the shown embodiments are:

[0328] After receiving the AI ​​service release message sent by the terminal, the NAS interface function sends an AI service resource release message to the policy charging function, and the carried parameters include the parameters carried in step 1.

[0329] This process supports releasing only AI resources or only communication resources.

[0330] Steps 3-8 belong to the release process of AI resources; steps 9-11 belong to the release process of communication resources; the order of the two parts is acceptable and can be determined by the policy charging function. The release of the other party is triggered only when one party is successfully released, otherwise the AI ​​service resource release response message is directly replied to indicate that the release failed. In the case that both parties are successfully released, the policy charging function can optionally execute step 12 to release at least one of the communication policy and AI policy associated with the AI ​​service.
