[0087] In related technologies, NWDAF is introduced to perform some intelligent analysis. Specifically, NWDAF has certain AI intelligent analysis functions. NWDAF collects some data and uses built-in algorithms and analysis capabilities to analyze some results and provide them to the 5th generation (5 thThe NWDAF is a core network element of the 5G (5G Generation) communication system, which performs some operation optimization or statistical analysis. However, the NWDAF cannot provide AI services for UEs.

[0088] In an embodiment of the present application, an AI session is established between an AI resource node and a UE, so that the AI ​​resource node provides services to the UE through the AI ​​session. That is, AI is provided as a service to the UE or a third party for use. After the AI ​​session is established, the network-side device or the third-party node can modify the AI ​​session.

[0089] To facilitate understanding of the session modification method provided in the embodiment of the present application, the following nouns or terms in the embodiment of the present application are first explained:

[0090] 1) The first service, which can also be called an AI service or a computing service, provides AI as a service to the terminal. For ease of explanation, the first service is illustrated as an AI service in the embodiments of this application, which is not a specific limitation.

[0091] 2) First session, the first session is the network resource allocated by the network side for the first service. When the first service is an AI service, the first session can also be called an AI session, which is the process of communication between the UE and the AI ​​resource node. After the AI ​​session is established, a data transmission channel between the UE and the AI ​​resource node is established. Therefore, if the UE wants to use AI services (such as AI data transmission), it must first establish an AI session. In other words, an AI session is an AI resource established between the UE and the AI ​​resource node. In addition, an AI session can sometimes also be referred to as an AI service connection or an AI connection.

[0092] 3) The first request message is used to request modification of the first session. For example, when the first session is an AI session, the first request message may be an AI session modification request message, an AI service bearer modification request message, or an AI bearer modification request message.

[0093] It should be noted that in some implementations, AI sessions have communication requirements (such as Quality of Service (QoS)). However, during the modification of an AI session, there is no restriction on whether to modify the AI ​​bearer or the communication bearer. That is, during the modification of an AI session, only AI resources, only communication resources, or both AI resources and communication resources can be modified.

[0094] 4) The logical functions of each functional network element in the embodiment of the present application are shown in Table 1 below:

[0095] Table 1

[0096] 5) The first network side device may include logical function network elements related to AI services, for example: the first network side device includes at least one of AI service management function, AI model management function, AI resource management function, AI resource node, and data plane management function.

[0097] It should be noted that the embodiments of the present application are mainly explained based on the logical functions of the network elements, but it does not limit whether at least two functional network elements are set together. For example, it does not limit whether the AI ​​service management function and the AI ​​resource node are the same functional node or different functional nodes. For another example, it does not limit whether the AI ​​service management function and the communication management function are the same functional node or different functional nodes. If two network elements with different logical functions are set together, the interaction process between the two logical functions is an internal process of the functional node, and the corresponding steps may not be executed. For the sake of convenience, the embodiments of the present application are generally explained by taking the network elements with logical functions set separately as an example, which does not constitute a specific limitation here.

[0098] 6) AI service data refers to data carried on the AI ​​session. In some embodiments, the AI ​​session can be transmitted using a communication bearer, that is, the user plane data of the AI ​​session is transmitted (via the UPF) to the AI ​​resource node for processing using the transmission channel of the existing communication bearer.

[0099] For ease of explanation, in the embodiments of the present application, a communication bearer is taken as a protocol data unit (PDU) session as an example. For example, an AI session can be transmitted using the data radio bearer (DRB) of the PDU session.

[0100] A PDU session refers to the process of communication between a UE and a data network (DN). Once a PDU session is established, a data transmission channel between the UE and the DN is established. Therefore, in related technologies, if a UE wants to transmit data to an application, it must first establish a PDU session. In other words, a PDU session is a communication resource established between a UE and an application in a 5G network.

[0101] In related technologies, the PDU session establishment process is briefly described as follows:

[0102] The UE initiates a PDU session establishment request to the network (sent to the SMF via the AMF). The UE allocates a PDU session ID and reports it to the network. The SMF allocates corresponding transmission resources (communication resources) for the UE's PDU session, including selecting the user plane node UPF and triggering the establishment of the user plane. After the user plane is established, the UE can use the user plane corresponding to the established PDU session for data transmission.

[0103] In related technologies, the PDU session modification process is briefly described as follows:

[0104] The UE initiates a PDU session modification request to the network (sent to the SMF via the AMF), where the UE carries information such as the PDU session identifier (Identity, ID), the requested Quality of Service rule (QoS rule), and the requested Quality of Service flow description (QoS Flow description); the SMF authorizes and modifies the corresponding PDU session based on the UE's request.

[0105] 7) AI Session ID, used to identify the AI ​​session. In some embodiments, the AI ​​Session ID is assigned by the UE when the AI ​​session is established and sent to the network. In some embodiments, the AI ​​Session ID is associated with the PDU Session ID, such as a one-to-one mapping or a many-to-one mapping. After determining the mapping, the UE sends it to the network when the AI ​​session is established. If multiple AI Session IDs are mapped to the same PDU Session ID, multiple AI sessions can be transmitted using the same PDU Session ID. That is, multiple AI Session IDs correspond to the same PDU Session ID.

[0106] 8) A first modification notification message, used to notify the first network side device to modify the service policy related to the first session, so as to trigger the first network side device to modify the notification message of the first session, which specifically includes a first notification message and a third notification message, wherein the first notification message is sent by the third network side device, and the third notification message is sent by the second network side device.

[0107] 9) A second modification notification message, used to notify the second network side device to modify the communication strategy related to the first session, so as to trigger the second network side device to modify the notification message of the communication bearer related to the first session, which specifically includes a second notification message and a fourth notification message, wherein the second notification message is sent by the first network side device and the fourth notification message is sent by the third network side device.

[0108] 10) First modification notification message confirmation (Acknowledgement, ACK), which is a response message to the above-mentioned first modification notification message, which specifically includes a first response message corresponding to the first notification message and a third response message corresponding to the third notification message.

[0109] 11) The second modification notification message ACK is a response message to the above-mentioned second modification notification message, which specifically includes a second response message corresponding to the second notification message and a fourth response message corresponding to the fourth notification message.

[0110] The following describes in detail the session modification method, session modification apparatus, and communication device provided in the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

The first network side device can have logical functions related to AI business, such as at least one of AI business management function, AI model management function, AI resource management function, and data plane management function, or the first network side device is an AI resource node, which is not specifically limited here.

[0112] As shown in FIG2 , the session modification method may include the following steps:

[0119] For ease of explanation, the embodiments of the present application are generally illustrated by taking the first service as an AI service as an example. In this case, the first session may be an AI session, and the first request message may be AI signaling or AI-related signaling.

[0120] Optionally, the first session satisfies at least one of the following:

[0123] Having at least one of a dedicated Data Network Name (DNN) and Single Network Slice Selection Assistance Information (S-NSSAI);

[0124] Having a quality of service (QoS) guarantee between the terminal and the first resource node;

[0125] Among them, the first resource node includes a network function for processing the first service, wherein the processing includes forwarding, caching, calculation, discarding and other processing types, and the processing content is AI service and / or computing service, for example: processing AI policy rules, performing AI service calculation processing according to the command of the AI ​​resource management function (user plane execution process), updating the AI ​​resource status to the AI ​​resource management function, and other operations.

[0126] In some embodiments, the first service requirement description information may be referred to as AI service requirement description information, which may be used to describe information related to the AI ​​service that needs to be modified. For example, the first service requirement description information may include at least one of the following:

[0127] An identifier of the first service, such as an inference service (specifically, an environment reconstruction service, a facial recognition service, etc.), or a training service;

[0128] Quality of Experience (QoE) requirements of the first service;

[0129] Quality of service (QoS) information of the first service, such as AI service processing latency, AI service processing accuracy, AI service computing load, and data processing scale;

[0130] Model information of the first service, such as model identification, model accuracy, model download address, etc.;

[0131] First indication information, where the first indication information indicates whether interaction with a target network function is required.

Optionally, at least one of the data plane management function, the AI ​​resource node, the AI ​​model management function, and the AI ​​resource management function sends the modified content to the AI ​​service management function.

[0160] It should be noted that while AI sessions have communication requirements (such as QoS), there is no restriction on whether to modify the AI ​​bearer and / or the communication bearer during the AI ​​session modification process.

[0215] It is worth mentioning that in addition to the above methods 1 to 3, the first network function can also trigger the modification of the AI ​​bearer, communication bearer or transmission mode of the first business data of the first session, which is not specifically limited here.

[0216] It should be noted that at least two of the first network function, the second network function, the third network function, the fourth network function and the first resource node can be jointly provided in the same network side device, or the first network function, the second network function, the third network function, the fourth network function and the first resource node can be respectively provided in different network side devices.

[0217] Among them, when the first network function, the second network function, the third network function, the fourth network function and the first resource node can be respectively set in different network side devices, the first network function needs to interact with the second network function, the third network function, the fourth network function and the first resource node respectively to realize the modification of the first session and feedback of the modification result.

The data source modification request message may carry the data source information that needs to be modified. Then, the data plane management function feeds back a data source modification response message to the AI ​​service management function.

Then, the AI ​​resource management function feeds back an AI resource modification response message to the AI ​​service management function.

[0265] Method 4: Interaction between the first network function and the first resource node to modify the bearer of the first session

[0266] In an optional implementation, when the first network side device is the first network function, the method further includes:

[0267] The first network-side device sends an eighth request message to the first resource node according to the first request message, where the eighth request message is used to request modification of the bearer of the first session, and the eighth request message includes service resource configuration information;

[0268] The first network-side device receives an eighth response message from the first resource node, where the eighth response message indicates a modification result of the bearer of the first session.

[0269] The eighth request message may be referred to as an AI bearer modification request message, which is used to request modification of the bearer of the first session. In addition, the eighth response message may be an AI bearer modification request response message.

[0270] Optionally, the eighth response message indicates the modification result of the bearer of the first session, which may be an AI bearer modification request response message including updated AI bearer information, or the AI ​​bearer modification response message is an AI bearer modification request message ACK or an AI bearer modification request message NACK.

[0272] For example, as shown in steps 5a and 5b in FIG4 , the AI ​​service management function sends an AI bearer modification request message to the AI ​​resource node. The AI ​​bearer modification request message may carry AI resource configuration information. The AI ​​resource node then feeds back an AI bearer modification response message to the AI ​​service management function. The AI ​​bearer modification response message may carry modified AI bearer information.

[0273] In an optional embodiment, the method further includes:

[0274] The first network-side device modifies the service policy of the first service according to the modified first session.

[0275] In some implementations, the service policy information includes at least one of the following:

[0276] Data transmission resource information related to the data of the first service, data forwarding rules related to the data of the first service, data caching rules related to the data of the first service, network context information related to the data of the first service; data matching strategy of the terminal side for the first session, and data sending strategy of the terminal side for the first session.

[0277] Among them, the data forwarding rules related to the data of the first business and the data caching rules related to the data of the first business are the data forwarding rules and data caching rules applied to the first business data on the network side; the data matching policy of the terminal side for the first session and the data sending policy of the terminal side for the first session are the data matching policy applied to the terminal side for matching the business data of the first session and the data sending policy for sending the business data of the first session.

[0278] In this embodiment, the AI ​​service management function may modify at least one of the following items of the AI ​​session based on the first request message: the transmission mode of the first service data, the service resources of the first service, the data source of the first service, the model of the first service, and the bearer of the first session. Subsequently, based on at least one of the modified items of information, the AI ​​policy may be modified. For example, as shown in Figure 3, the AI ​​service management function may trigger the AI ​​policy modification process based on the information obtained in steps 1a to 1d.

[0279] In some embodiments, the first network-side device may further send a notification message to at least one of the terminal and the AI ​​resource node. As shown in step 2a in FIG3 , the AI ​​service management function sends an information update notification message to the AI ​​resource node based on the information obtained in steps 1a to 1d to notify the AI ​​resource node of at least one of the modified session information and the modified AI policy of the first session.

[0280] Thereafter, the AI ​​resource node may provide AI services to the terminal through the AI ​​session according to the modified session information or the modified AI policy information of the first session.

[0281] In an optional implementation, when the first information includes the first request message, the first network-side device obtains the first information, including:

[0283] The first communication device may be at least one of an application function (AF), an over the top (OTT, i.e. an Internet company bypasses an operator) server and a terminal.

[0285] In some embodiments, as shown in FIG4 , after receiving the first request message and modifying the first session, the first network-side device may send a first response message to the first communication device, where the first response message indicates the modification result of the first session. For example, the AI ​​service management function informs the first communication device of at least one of the following information: the session ID, QoS information, AI policy information, AI resource configuration information, data source information, model information, etc., of the modified first session via the first response message.

[0286] Alternatively, the first response message may not include the modified session information of the first session, such as the AI ​​service management function feeds back the first request message ACK or the first request message NACK to the first communication device.

[0287] In other embodiments, as shown in FIG5, FIG6, or FIG7, after receiving a first request message sent by a first communication device, the NEF may authenticate the first request message and store the parameters requested in the first request message in the UDR. In addition, the NEF feeds back a first response message to the first communication device based on the authentication result of the first request message. The first response message may be used to indicate the request result of the first request message. Thereafter, the UDR may notify the policy charging function to update policy information based on the stored information, wherein the policy information includes AI-related policies (i.e., AI policies) and communication-related policies (i.e., communication policies).

[0288] In one embodiment, after the policy charging function updates the AI ​​policy information, it may notify the AI ​​service management function to modify the AI ​​session accordingly.

[0289] For example, the first network-side device obtains the first information, including:

[0290] The first network side device receives a first notification message from a third network side device, where the first notification message is used to notify the first network side device to modify the first session.

[0291] The third network side device may be a policy charging function network element.

[0292] Optionally, the method further includes:

[0293] The first network-side device sends a first response message to the third network-side device, where the first response message indicates a modification result of the first session.

[0294] In another embodiment, after the policy charging function updates the communication policy information, it may notify the communication management function to modify the communication bearer related to the AI ​​session accordingly.

[0295] It should be noted that the modification of the AI ​​session and the modification of the communication bearer related to the AI ​​session can be two independent processes. For example, as shown in Figure 5, when the policy charging function updates the AI ​​policy information and the communication policy information, it sends a first notification message to the AI ​​service management function and a second notification message to the communication management function. The first notification message can notify the AI ​​service management function to modify the AI ​​session, such as AI session modification, AI rule modification, or UE policy modification; the second notification message can notify the communication management function to modify the communication bearer related to the AI ​​session.

[0296] Of course, the modification of the AI ​​session and the modification of the communication bearer related to the AI ​​session may be two related processes.

[0297] In some embodiments, the policy charging function determines QoS information for the AI ​​session based on QoS information between the communication resource node and the AI ​​resource node. In some embodiments, the policy charging function determines QoS information for the AI ​​communication bearer based on the AI ​​session information.

[0298] Optionally, the first notification message includes at least one of the following:

[0299] Second information, such as PDU session information, is used to instruct the network to allocate communication resources corresponding to the AI ​​session. It includes: PDU session ID, PDU session type, QoS information (including: QoS flow identifier, QoS rules, QoS flow description information, etc.), DNN, S-NSSAI;

[0300] The third information, such as AI session information, is used to describe an AI session, including: AI session ID, AI session type, DNN related to the AI ​​session, slices related to the AI ​​session, and QoS information related to the AI ​​session (including: QoS flow identifier, QoS rules, QoS flow description information, etc.).

[0301] In some embodiments, the method further comprises:

[0302] The first network-side device sends fifth information to the second network-side device, where the fifth information includes at least one of the following:

[0303] modified session information of the first session;

[0304] A second notification message, wherein the second notification message is used to instruct modification of a communication bearer or a communication policy related to the first session.

[0305] Among them, the second network side device can be a communication management function network element.

[0306] Optionally, the second notification message includes at least one of the following:

[0307] Second information, such as PDU session information, is used to instruct the network to allocate communication resources corresponding to the AI ​​session. It includes: PDU session ID, PDU session type, QoS information (including: QoS flow identifier, QoS rules, QoS flow description information, etc.), DNN, S-NSSAI;

[0308] The third information, such as AI session information, is used to describe an AI session, including: AI session ID, AI session type, DNN related to the AI ​​session, slices related to the AI ​​session, and QoS information related to the AI ​​session (including: QoS flow identifier, QoS rules, QoS flow description information, etc.).

[0309] In one embodiment, after the AI ​​service management function completes the AI ​​session modification, the AI ​​service management function can determine how to modify the communication bearer or communication strategy related to the first session based on the modified first session, thereby notifying the communication management function through a second notification message to modify the communication bearer or communication strategy related to the first session according to the second notification message.

[0310] For example, as shown in FIG6 , after updating the AI ​​policy information, the policy charging function sends a first notification message to the AI ​​service management function through step 5 to notify the AI ​​service management function to modify the AI ​​session. After the AI ​​service management function completes the modification of the AI ​​session through steps 6 to 8, it can directly send a second notification message to the communication management function through step 10b to notify the communication management function to modify the communication bearer related to the AI ​​session.

[0311] As another example, as shown in FIG3 , after the AI ​​service management function modifies the AI ​​session or AI policy, the AI ​​service management function sends the modified session information of the AI ​​session to the communication management function in step 3, so that the communication management function modifies the communication bearer or communication policy associated with the AI ​​session based on the modified session information of the AI ​​session. Alternatively, as shown in step 4 in FIG3 , after the AI ​​service management function modifies the AI ​​session or AI policy, the communication management function sends a second notification message (e.g., a communication bearer modification notification) to notify the communication management function to modify the communication bearer or communication policy associated with the AI ​​session in accordance with the second notification message.

[0312] Optionally, the second notification message includes second indication information, and the second indication information instructs the second network side device to modify the QoS information of the communication bearer related to the first session.

[0313] For example: the communication bearer is updated according to the end-to-end QoS requirement between the terminal and the first resource node, and the QoS requirement between the communication resource node (such as UPF) and the first resource node.

[0314] Optionally, the method further includes:

[0315] The first network-side device receives a second response message from the second network-side device, where the second response message is a response message to the second notification message.

[0316] In another embodiment, after completing the AI ​​session modification, the AI ​​service management function may send the modified session information of the first session to the communication management function, such as at least one of the service policy information, service resource configuration information, data source information, and model information. In this way, the communication management function may trigger the modification of at least one of the communication bearer or communication policy related to the first session based on the modified session information of the first session, such as the communication management function initiating a PDU session modification process based on the modified session information of the first session.

[0317] It is worth mentioning that the above two implementation methods can be combined, for example: the first network side device sends the modified session information of the first session and the second notification message to the communication management function, so that the communication management function decides whether to modify the communication bearer related to the first session according to the notification of the second notification message based on the modified session information of the first session.

[0318] Optionally, the communication strategy includes relevant strategies for communication or routing on the network side or the terminal side;

[0319] In some implementations, the communication policy modification process is an SM policy association modification process.

[0320] In some implementations, the communication policy modification process is a UE policy modification process.

[0321] In some embodiments, the communication policy modification process is used to modify routing information in the network, such as forwarding action rules (FAR), packet detection rules (PDR),

[0322] In this implementation, after the first session is modified, fifth information may be sent to the communication management function so that the communication management function triggers modification of the communication bearer or communication policy related to the first session.

[0323] In another embodiment, after completing the AI ​​session modification, the AI ​​service management function can feedback the AI ​​session modification result to the policy billing function, so that the policy billing function sends a fourth notification message to the communication management function according to the AI ​​session modification result, so that the communication management function modifies the communication-related policy according to the fourth notification message.

[0324] For example, as shown in FIG6 , after the AI ​​service management function completes the modification of the AI ​​session through steps 6 to 8, it may feedback the modification result of the AI ​​session to the policy and charging function through step 9. In step 10a, the policy and charging function sends a fourth notification message to the communication management function based on the modified AI session to notify the communication management function to modify the communication bearer related to the AI ​​session.

[0325] Of course, in addition to modifying the communication strategy based on the modification results of the AI ​​strategy as described above, it is also possible to modify the communication strategy first and then modify the AI ​​strategy based on the modification results of the communication strategy.

[0326] For example: as shown in Figure 7, after updating the communication policy information, the policy charging function sends a second notification message to the communication management function through step 5 to notify the communication management function to modify the communication bearer related to the AI ​​session; after the communication management function completes the modification of the communication bearer through at least one of steps 6a and 6b, it can directly send a first notification message to the AI ​​service management function through step 8b to notify the AI ​​service management function to modify the AI ​​session, or, after the communication management function completes the modification of the communication session through at least one of steps 6a and 6b, it can feedback the modification result of the communication bearer to the policy charging function through step 7, and in step 8a, the policy charging function sends a first notification message to the AI ​​service management function based on the modified communication bearer to notify the AI ​​service management function to modify the AI ​​session.

[0327] As an optional implementation manner, the first network side device obtains the first information, including:

[0328] The first network side device receives a third notification message from the second network side device, where the third notification message is used to notify the first network side device to modify a service policy related to the first session;

[0329] The first network-side device modifies the first session according to the first information, including:

[0330] The first network-side device modifies the service policy related to the first session according to the third notification message, and modifies the first session according to the modified service policy.

[0331] Among them, the third notification message is similar to the above-mentioned first notification message, and the differences include: the first notification message is a notification message sent by a third network-side device, such as a notification message sent by a policy billing function to notify the AI ​​service management function to modify the AI ​​policy, and the third notification message is sent by a second network-side device, such as a notification message sent by a communication management function to the AI ​​service management function to notify the AI ​​service management function to modify the AI ​​policy related to the communication policy after modifying the communication policy. The content of the third notification message will not be repeated here.

[0332] In this implementation, the communication policy may be modified first by the second network side device, and then the second network side device may notify the first network side device to modify the AI ​​session related to the communication policy.

[0333] It should be noted that after modifying the communication policy, the second network side device may feed back the communication policy modification result to the policy charging function, and the policy charging function may notify the first network side device to modify the first session based on the communication policy modification result.

[0334] In addition, the modification process of the first session and the modification process of the communication bearer related to the first session can be two independent processes that can be executed in parallel, or, the first session can be modified first, and the modification process of the communication bearer related to the first session can be triggered based on the modification result of the first session, or, the communication bearer can be modified first, and the modification process of the first session related to the communication bearer can be triggered based on the modification result of the communication bearer.

[0335] Method 1: Modify AI bearer and communication bearer independently

[0336] In this implementation manner, the third network-side device sends a first notification message to the first network-side device and sends a fourth notification message to the second network-side device according to the fifth notification message.

[0337] For example, as shown in Figure 5, the interaction process between the policy charging function, the communication management function, and the AI ​​service management function includes:

[0338] Step 5: The policy charging function sends a fourth notification message to the communication management function, which is used to modify communication-related policies, such as communication bearer modification, communication rule modification, and UE policy modification.

[0339] Step 6a, the communication management function modifies the communication bearer based on step 5;

[0340] Step 6b, the communication management function modifies the communication rules based on step 5;

[0341] Step 7: The policy charging function sends a first notification message to the AI ​​service management function to modify AI-related policies, such as AI session modification, AI rule modification, and UE policy modification.

[0342] It is worth mentioning that step 5 and step 7 can be triggered independently and executed in parallel.

[0343] Method 2: Modify the AI ​​bearer first, then modify the communication bearer

[0344] In some implementation manners, the first network-side device obtaining the first information includes:

[0345] The first network side device receives a first notification message from a third network side device, where the first notification message is used to notify the first network side device to modify the first session;

[0346] The method further comprises:

[0347] The first network-side device sends a first response message to the third network-side device, where the first response message indicates a modification result of the first session.

[0348] The first response message is a response message to the first notification message. For example, the first notification message is a first modification notification message, and the first response message is a first modification notification message ACK. The first response message may indicate a modification result of the first session, such as a modified AI session ID, an AI policy, and the like.

[0349] In one embodiment, the third network side device sends a fourth notification message to the second network side device according to the fifth notification message, including:

[0350] The third network side device sends a fourth notification message to the second network side device according to the modification result of the first session.

[0351] For example: as shown in steps 4 to 10a in Figure 6, when the policy charging function receives the policy update notification (i.e., the fifth notification message), it first sends a first notification message to the AI ​​service management function to notify the AI ​​service management function to modify the AI ​​session. After completing the AI ​​session modification, the AI ​​service management function feeds back a first response message to the policy charging function, which indicates the modification result of the first session. Then, the policy charging function can send a fourth notification message to the communication management function based on the session information of the modified AI session to trigger the communication management function to modify the communication bearer.

[0352] In another embodiment, after the first network side device completes the modification of the first session, the fifth information is directly sent to the second network side device to trigger the second network side device to modify the communication bearer.

[0353] For example: as shown in steps 4 to 6 and step 10b in Figure 6, upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function sends a first notification message to the AI ​​service management function to notify the AI ​​service management function to modify the AI ​​session. After completing the AI ​​session modification, the AI ​​service management function sends a second notification message to the communication management function to trigger the communication management function to modify the communication bearer. The second notification message is used to instruct the modification of the communication bearer or communication policy related to the first session.

[0354] In this implementation, the first network side device may send fifth information to the second network side device in the modified AI session to trigger the second network side device to modify the communication bearer.

[0355] Method 3: Modify the communication bearer first, then modify the AI ​​bearer

[0356] In some implementation manners, the first network-side device obtaining the first information includes:

[0357] The first network side device receives a first notification message from a third network side device, where the first notification message is used to notify the first network side device to modify the first session.

[0358] Prior to this, the third network side device first sent a fourth notification message to the second network side device, and obtained a fourth response message fed back by the second network side device. The above-mentioned first notification message was determined based on the modification result of the communication bearer related to the first session indicated by the fourth response message.

[0359] For example, as shown in steps 4 to 8a in FIG7 , upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function first sends a fourth notification message to the communication management function to notify the communication management function to modify the communication bearer related to the AI ​​session. After completing the communication bearer modification, the communication management function feeds back a fourth response message to the policy charging function, where the fourth response message indicates the modification result of the communication bearer related to the AI ​​session. Then, the policy charging function may send a first notification message to the AI ​​service management function based on the modified communication bearer related to the AI ​​session to trigger the AI ​​service management function to modify the AI ​​session.

[0360] In another embodiment, the first network-side device obtains the first information, including:

[0361] The first network side device receives a third notification message from the second network side device, and the third notification message is used to notify the first network side device to modify the service policy related to the first session

[0362] After completing the modification of the communication bearer related to the first session, the second network side device directly sends a third notification message to the first network side device to trigger the first network side device to modify the service policy related to the first session.

[0363] For example, as shown in steps 4 to 6b and step 8b in FIG7 , upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function sends a fourth notification message to the communication management function to notify the communication management function to modify the communication bearers related to the AI ​​session. After completing the modification of the communication bearers related to the AI ​​session, the communication management function sends a third notification message to the AI ​​service management function to trigger the AI ​​service management function to modify the AI ​​session.

[0364] As an optional implementation, the method further includes:

[0365] The first network-side device sends a first command message to the terminal, where the first command message is used to instruct the terminal to modify the first session.

[0366] Optionally, the first command includes at least one of the following:

[0367] Describing information on the requirements of the first service;

[0368] a session type indication, where the session type indicates the type of the modified session;

[0369] third information, where the third information is used to indicate information related to the first session;

[0370] a data transmission instruction, wherein the data transmission instruction instructs the terminal to send service data associated with the demand description information of the first service;

[0371] A data transmission mode indicates a transmission mode in which the terminal sends service data associated with the demand description information of the first service.

[0372] Optionally, the third information includes at least one of the following:

[0373] The session ID of the first session, the session type of the first session, the DNN related to the first session, the slice related to the first session, and the QoS information related to the first session.

[0374] In this implementation, the terminal may be instructed to transmit AI service data according to the modified AI session through the first command message.

[0375] In an embodiment of the present application, a first network-side device obtains first information; wherein the first information includes at least one of the following: demand description information of the first service; service resource configuration information; a first request message, wherein the first request message is used to request modification of the first session; the first network-side device modifies the first session based on the first information, wherein the first session is used to carry service data of the first service of the terminal, wherein the first service includes at least one of an artificial intelligence (AI) service and a computing service. In this way, the first network-side device can modify the first session for at least one of the AI ​​service and the computing service based on its own needs or the request of other devices.

[0376] Referring to FIG8 , another session modification method provided in an embodiment of the present application is performed by a second network-side device. As shown in FIG8 , the session modification method performed by the second network-side device includes the following steps:

[0377] Step 801: The second network side device obtains fourth information.

[0378] The fourth information includes at least one of the following:

[0379] fifth information, the fifth information including the modified session information of the first session, or a second notification message from the first network-side device, the second notification message being used to instruct modification of a communication bearer or a communication policy related to the first session;

[0380] A fourth notification message from the third network-side device, where the fourth notification message is used to notify the second network-side device to modify a communication policy related to the first session.

[0381] Step 802: The second network-side device modifies the communication bearer related to the first session according to the fourth information, where the first session is used to carry business data of a first business, and the first business includes at least one of an artificial intelligence (AI) business and a computing business.

[0382] It should be noted that in the embodiment of the present application, the meanings of the above-mentioned fifth information, first session, first service, second notification message, communication bearer, communication strategy, first network side device, second network side device and third network side device are the same as the meanings of the fifth information, first session, first service, second notification message, communication bearer, communication strategy, first network side device, second network side device and third network side device in the method embodiment shown in Figure 2. The specific meanings can be referred to the explanation in the method embodiment shown in Figure 2, and will not be repeated here.

[0383] In addition, the above-mentioned fourth notification message may be similar to the above-mentioned second notification message, with the following differences: the second notification message is sent by the first network side device, such as the AI ​​service management function sending a notification message to the communication management function after modifying the AI ​​session or AI policy to notify the communication management function to modify the communication bearer related to the AI ​​session or modify the communication policy related to the AI ​​policy, while the fourth notification message is a notification message sent by the third network side device, such as a notification message sent by the policy billing function to notify the communication management function to modify the communication policy. The content of the fourth notification message will not be repeated here.

[0384] Optionally, the first session satisfies at least one of the following:

[0385] A bearer between the terminal and the first resource node;

[0386] A first identifier that uniquely identifies the first session;

[0387] Having at least one of a dedicated data network name DNN and single network slice selection auxiliary information S-NSSAI;

[0388] Having a quality of service (QoS) guarantee between the terminal and the first resource node;

[0389] The first resource node includes a network function for processing the first service.

[0390] In some implementations, the communication bearer or communication policy modification process may be triggered based on the modification result of the first network-side device on the first session or the modification result on the first service-related policy.

[0391] For example: as shown in Figure 3 or Figure 4, after modifying the AI ​​session or AI policy, the AI ​​service management function sends fifth information to the communication management function, such as the modified session information of the first session, and / or a second notification message, where the second notification message is used to indicate the modification of the communication bearer or communication policy related to the first session.

[0392] For another example: As shown in Figure 6, after modifying the AI ​​session or AI policy, the AI ​​service management function sends a second notification message to the communication management function through step 10b, or feeds back the modification result of the AI ​​session to the policy billing function through step 9. Thereafter, the policy billing function can send a fourth notification message to the communication management function through step 10a based on the modification result of the AI ​​session.

[0393] Optionally, the business policy includes at least one of the following:

[0394] Data transmission resource information related to the data of the first service, data forwarding rules related to the data of the first service, data caching rules related to the data of the first service, network context information related to the data of the first service; data matching strategy of the terminal side for the first session, and data sending strategy of the terminal side for the first session.

[0395] Optionally, the communication strategy includes at least one of the following:

[0396] Data transmission resource information related to the communication of the first session, data caching rules related to the communication of the first session, data forwarding rules related to the communication of the first session, network context information related to the communication of the first session, terminal side data matching strategy for the communication bearer related to the first session, and terminal side data sending strategy for the communication bearer related to the first session.

[0397] In some implementations, modifying the communication bearer is a process of modifying a PDU session.

[0398] In some implementations, modifying the communication bearer is modifying communication QoS related information.

[0399] In some implementations, modifying the communication policy is used to modify relevant policies for communication or routing on the network or terminal side.

[0400] For example, the communication policy modification process is an SM policy association modification process, or a terminal policy modification process, or is used to modify routing information in the network, such as a forwarding action rule (FAR) and a packet detection rule (PDR).

[0401] Optionally, the session information includes at least one of the following:

[0402] Business strategy information, business resource configuration information, data source information, and model information.

[0403] Optionally, when the fourth information includes a second notification message from the first network-side device, the method further includes:

[0404] The second network-side device sends a second response message to the first network-side device, where the second response message is a response message to the second notification message.

[0405] For example: as shown in Figure 3 or Figure 4, after the communication management function modifies the communication bearer or communication policy related to the AI ​​session according to the second notification message sent by the AI ​​business management function, the communication management function feeds back a communication bearer modification confirmation (Acknowledgement, ACK) to the AI ​​business management function.

[0406] As an optional implementation manner, when the fourth information includes the fourth notification message, the second network side device modifies the communication bearer related to the first session according to the fourth information, including:

[0407] The second network-side device modifies the communication policy related to the first session according to the fourth notification message;

[0408] The second network-side device modifies the communication bearer or communication rules related to the first session according to the modified communication policy.

[0409] For example, as shown in Figure 5, in step 5, the policy charging function sends a fourth notification message to the communication management function, which is used to modify communication-related policies, such as communication bearer modification, communication rule modification, and UE policy modification. Thereafter, the communication management function modifies the communication bearer or communication rule based on step 5.

[0410] In some implementations, modification of the communication bearer or the communication policy may trigger the first network-side device to modify the first session or modify the first service-related policy.

[0411] As an optional implementation manner, when the fourth information includes the fourth notification message, the method further includes:

[0412] The second network side device sends a fourth response message to the third network side device, where the fourth response message indicates a modification result of the communication bearer related to the first session;

[0413] or,

[0414] The second network side device sends a third notification message to the first network side device, where the third notification message is used to notify the first network side device to modify a service policy related to the first session.

[0415] In one embodiment, as shown in step 7 of FIG. 7 , after modifying the communication bearer or communication policy, the communication management function sends a fourth response message to the policy charging function to indicate the modification result of the communication bearer related to the first session. Thereafter, the policy charging function may send a first notification message to the AI ​​service management function network element based on the modification result of the communication bearer to notify the AI ​​service management function network element to modify AI-related policies, such as AI session modification, AI rule modification, and UE policy modification.

[0416] In another embodiment, as shown in step 8b in Figure 7, after modifying the communication bearer or communication policy, the communication management function sends a third notification message to the AI ​​service management function network element to notify the AI ​​service management function network element to modify AI-related policies, such as AI session modification, AI rule modification, and UE policy modification.

[0417] The embodiment of the present application can be combined with the method embodiment shown in Figure 2, so that the second network side device can modify the communication bearer or communication policy related to the AI ​​session based on the modification result of the first session by the first network side device or the modification notification of the third network side device. It will not be repeated here.

[0418] Please refer to FIG9 , which is a flowchart of another session modification method provided in an embodiment of the present application. The session modification method is performed by a third network-side device. As shown in FIG9 , the session modification method includes the following steps:

[0419] Step 901: The third network side device receives a fifth notification message, where the fifth notification message is used to notify the third network side device to modify the service policy related to the first session, or to modify the communication policy related to the first session; the first session is used to carry service data of the first service, and the first service includes at least one of an artificial intelligence AI service and a computing service.

[0420] Step 902: The third network-side device performs at least one of the following according to the fifth notification message:

[0421] Sending a first notification message to a first network-side device, where the first notification message is used to notify the first network-side device to modify the first session;

[0422] A fourth notification message is sent to the second network side device, where the fourth notification message is used to notify the second network side device to modify the communication policy related to the first session.

[0423] Optionally, the first session satisfies at least one of the following:

[0424] A bearer between the terminal and the first resource node;

[0425] A first identifier that uniquely identifies the first session;

[0426] Having at least one of a dedicated data network name DNN and single network slice selection auxiliary information S-NSSAI;

[0427] Having a quality of service (QoS) guarantee between the terminal and the first resource node;

[0428] The first resource node includes a network function for processing the first service.

[0429] Among them, the above-mentioned third network side device can be a policy billing function network element, and the fifth notification message can come from the UDR. For example: as shown in Figures 5 to 7, the first communication device, such as an OTT server or AF or terminal, sends an AI session modification request message to the NEF, and the NEF responds to the AI ​​session modification request message and feeds back a first response message to the first communication device based on the authentication result. The AI ​​session modification response message can be used to indicate the request result of the AI ​​session modification request message. In addition, the NEF stores the requested parameters in the AI ​​session modification request message in the UDR, and the UDR sends a policy update notification to the policy billing function based on the stored information to notify the policy billing function to update the policy information. The policy information includes AI-related policies (i.e., AI policies) and communication-related policies (i.e., communication policies). At this time, the above-mentioned fifth notification message is a policy update notification from the UDR.

[0430] Optionally, when the third network-side device sends the first notification message to the first network-side device according to the fifth notification message, the method further includes:

[0431] The third network-side device receives a first response message from the first network-side device, where the first response message indicates a modification result of the first session.

[0432] For example, assuming that the first notification message is a first modification notification message, the first response message may be a first modification notification message ACK.

[0433] Optionally, when the third network side device sends a fourth notification message to the second network side device according to the fifth notification message, the method further includes:

[0434] The third network-side device receives a fourth response message from the second network-side device, where the fourth response message indicates a modification result of the communication bearer related to the first session.

[0435] For example, assuming that the fourth notification message is the second modification notification message, the fourth response message may be the second modification notification message ACK.

[0436] In one embodiment, the third network device sends a first notification message to the first network device and a fourth notification message to the second network device based on the fifth notification message. In this case, the first notification message is used to trigger the first network device to modify the first session, and the fourth notification message is used to trigger the second network device to modify the communication bearer.

[0437] In this implementation, the modification process of the first session and the modification process of the communication bearer are two independent processes that can be executed in parallel.

[0438] In another implementation, the first session may be modified first, and then the modification of the communication bearer may be triggered according to the modification result of the first session.

[0439] Optionally, the third network side device sending a fourth notification message to the second network side device according to the fifth notification message includes:

[0440] The third network side device sends a fourth notification message to the second network side device according to the modification result of the first session.

[0441] The modification result of the first session may be obtained based on the first response message received by the third network-side device.

[0442] For example: as shown in steps 4 to 10a in Figure 6, upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function first sends a first notification message to the AI ​​service management function to notify the AI ​​service management function to modify the AI ​​session. After completing the AI ​​session modification, the AI ​​service management function feeds back a first response message to the policy charging function, which indicates the modification result of the AI ​​session. Then, the policy charging function can send a fourth notification message to the communication management function based on the session information of the modified AI session to trigger the communication management function to modify the communication bearer.

[0443] In another embodiment, after completing the modification of the first session, the first network side device directly sends the fifth information to the second network side device to trigger the second network side device to modify the communication bearer.

[0444] For example: as shown in steps 4 to 6 and step 10b in Figure 6, upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function sends a first notification message to the AI ​​service management function to notify the AI ​​service management function to modify the AI ​​session. After completing the AI ​​session modification, the AI ​​service management function sends a second notification message to the communication management function to trigger the communication management function to modify the communication bearer. The second notification message is used to instruct the modification of the communication bearer or communication policy related to the first session.

[0445] In yet another embodiment, the communication bearer may be modified first, and then the modification of the first session may be triggered according to the modification result of the communication bearer.

[0446] Optionally, the third network-side device sending a first notification message to the first network-side device according to the fifth notification message includes:

[0447] The third network side device sends a first notification message to the first network side device according to the modification result of the communication bearer related to the first session.

[0448] The modification result of the communication bearer related to the first session can be obtained based on the fourth response message received by the third network side device.

[0449] For example, as shown in steps 4 to 8a in FIG7 , upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function first sends a fourth notification message to the communication management function to notify the communication management function to modify the communication bearer related to the AI ​​session. After completing the communication bearer modification, the communication management function feeds back a fourth response message to the policy charging function, where the fourth response message indicates the modification result of the communication bearer related to the AI ​​session. Then, the policy charging function may send a first notification message to the AI ​​service management function based on the modified communication bearer related to the AI ​​session to trigger the AI ​​service management function to modify the AI ​​session.

[0450] In another embodiment, after completing the modification of the communication bearer related to the first session, the second network side device directly sends a third notification message to the first network side device to trigger the first network side device to modify the service policy related to the first session.

[0451] For example, as shown in steps 4 to 6b and step 8b in FIG7 , upon receiving the policy update notification (i.e., the fifth notification message), the policy charging function sends a fourth notification message to the communication management function to notify the communication management function to modify the communication bearers related to the AI ​​session. After completing the modification of the communication bearers related to the AI ​​session, the communication management function sends a third notification message to the AI ​​service management function to trigger the AI ​​service management function to modify the AI ​​session.

[0643] In the third embodiment, taking the example of a first network-side device being an AI model management function, a second network-side device being a communication management function, and a third network-side device being a policy-based charging function, as shown in Figure 5 , the NEF authenticates the first request message from the first communication device (such as an OTT server or AF) and stores the modified parameters in the first request message in the UDR. The UDR can, based on the stored information, notify the policy-based charging function to update policy information, including AI-related policies (i.e., AI policies) and communication-related policies (i.e., communication policies).

[0644] In some implementations, the policy charging function may notify the AI ​​service management function to modify the AI ​​session accordingly based on the updated policy information, and notify the communication management function to modify the communication bearer accordingly.

[0645] In the fourth embodiment, taking the example of a first network-side device being an AI model management function, a second network-side device being a communication management function, and a third network-side device being a policy-based charging function, as shown in FIG6 , the NEF authenticates the first request message from the first communication device (such as an OTT server or AF) and stores the modified parameters in the first request message in the UDR. The UDR can, based on the stored information, notify the policy-based charging function to update policy information, including AI-related policies (i.e., AI policies) and communication-related policies (i.e., communication policies).

[0646] Thereafter, the policy and charging function may notify the AI ​​service management function based on the updated AI policy information to modify the AI ​​session accordingly, and trigger modification of the communication bearer associated with the AI ​​session based on the modification results of the AI ​​session. For example, the AI ​​service management function may feed back the modification results of the AI ​​session to the policy and charging function, and the policy and charging function may send a second modification notification message to the communication management function based on the modification results of the AI ​​session to notify the communication management function to modify the communication bearer; or, the AI ​​service management function may send a second modification notification message to the communication management function based on the modification results of the AI ​​session to notify the communication management function to modify the communication bearer.

[0647] In the fifth embodiment, taking the example of the first network-side device being an AI model management function, the second network-side device being a communication management function, and the third network-side device being a policy-based charging function, as shown in FIG7 , the NEF authenticates the first request message from the first communication device (such as an OTT server or AF) and stores the modified parameters in the first request message in the UDR. The UDR can notify the policy-based charging function to update policy information based on the stored information, wherein the policy information includes AI-related policies (i.e., AI policies) and communication-related policies (i.e., communication policies).

[0648] Thereafter, the policy charging function may notify the communication management function to modify the communication bearer accordingly based on the updated communication policy information, and trigger modification of the AI ​​session associated with the communication bearer based on the modification result of the communication bearer. For example, the communication management function feeds back the modification result of the communication bearer to the policy charging function, and the policy charging function sends a first modification notification message to the AI ​​service management function based on the modification result of the communication bearer to notify the AI ​​service management function to modify the AI ​​session; or, the communication management function sends a first modification notification message to the AI ​​service management function based on the modification result of the communication bearer to notify the AI ​​service management function to modify the AI ​​session.
