[0048] In the related art, it is not clear what information is used to determine the ATSSS rules, and how to determine the ATSSS rules. This application takes into account that NWDAF (Network Data Analytics Function) has certain artificial intelligence (AI) analysis functions, and can use NWDAF to analyze the relevant data of historical upstream traffic or downstream traffic, and then determine the allocation rules according to the analysis results provided by NWDAF. In this way, this application clarifies the determination of ASSSS rules based on the analysis results provided by NWDAF. Moreover, because the analysis results provided by NWDAF are obtained by performing AI artificial intelligence analysis on the relevant data of historical upstream traffic or downstream traffic, the accuracy of the ATSSS rules determined based on the analysis results provided by NWDAF is higher.

[0049] To facilitate understanding of the technical solutions provided by the present application, the main technical concepts involved in the embodiments of the present application are briefly described below.

[0050] ATSSS Architecture:

[0051] The ATSSS feature can realize multi-access PDU connectivity service (multi-access PDU Connectivity Service), such as Figure 2 As shown, the UE accesses the network or transmits data through two access modes (e.g., 3GPP access or non-3GPP access) or access network technologies. These two accesses respectively establish two independent N3 / N9 tunnels between the PDU Session Anchor PSA (PSA) and the Radio Access Network (RAN) or Access Network (AN), and simultaneously implement PDU exchange between the UE and the data network. A multi-access PDU session is implemented by establishing a multi-access PDU session, that is, a PDU session can have user plane resources on two access networks.

[0052] In other words, ATSSS is a multi-access PDU session established by the network side device for the UE. The multi-access PDU session is established in two access modes at the same time, and the UE transmits data or accesses the network in two access modes at the same time. A multi-access PDU session can be accessed in two access modes at the same time, for example, one 5G access and one satellite access.

[0053] In the embodiment of the present application, the first access method or the second access method is two access methods for a multi-access PDU session.

[0054] The first access mode or the second access mode may be 3GPP access or non-3GPP access.

[0055] The 3GPP access includes but is not limited to at least one of the following:

[0056] 5G access;

[0057] LTE or 4G access;

[0058] Satellite access;

[0059] Non-3GPP access includes but is not limited to at least one of the following:

[0060] WLAN;

[0061] Wifi;

[0062] Fixed network access.

[0063] ATSSS Rules:

[0064] ATSSS rule is a multi-access strategy for UE or UPF. ATSSS rules are arranged in a priority order and used by UE and UPF. UE uses ATSSS rules to determine how to handle uplink traffic (for example, which access mode to use for uplink traffic, or how to use different access modes for uplink traffic), and UPF uses ATSSS rules to determine how to handle downlink traffic.

[0065] The ATSSS rules include two parts:

[0066] 1) Traffic descriptor: Traffic descriptor is used to identify the sender and receiver of traffic. For example, the destination IP address is used to identify the object or destination server to which the traffic is to be sent (i.e., to which server or target address the traffic will be sent), and the application descriptor is used to identify the sender of the traffic (i.e., which application on the UE sends the traffic).

[0067] 2) Access Selection Descriptor (ASD): Access Selection Descriptor refers to the usage rules of traffic, that is, how to distribute uplink traffic or downlink traffic on two access modes. After the UE or UPF uses the traffic descriptor to identify the traffic, the corresponding ASD is used for the identified traffic.

[0068] Specifically, the structure of the ATSSS rule is shown in Table 1:

[0069] Table 1 Structure of ATSSS rules

[0070]

[0071]

[0072]

[0073]

[0074] NWDAF:

[0075] At present, NWDAF is introduced in 3GPP for intelligent analysis. NWDAF has certain AI analysis functions. NWDAF collects data and uses built-in algorithms and analysis capabilities to obtain analysis results, and then provides the analysis results to 5G core network elements for operation optimization or statistical analysis.

[0076] For example, NWDAF can provide an observed service experience analysis function (Observed Service Experience related network data analytics), which can collect the service quality (Quality of Service, QoS) information (such as uplink and downlink rates, packet loss rate, etc.) of the terminal accessing a server address (such as the IP address corresponding to the Tencent server) and output a statistical information, which includes the user experience of the UE accessing the server. NWDAF can also make predictions based on the historical experience of the UE accessing the server, such as if the UE accesses the server in a certain time period and area in the future, what the UE's possible user experience will be (such as QoS).

[0077] Usually, the analysis or prediction content that NWDAF can provide is distinguished by the Analytic ID. By indicating different Analytic IDs and related parameters to NWDAF, NWDAF can provide analysis and prediction. For example, the observation service experience analysis provided by the above NWDAF uses Analytic ID = Service experience; therefore, as long as the network element that obtains the NWDAF service enters the Analytic ID when requesting analysis, NWDAF can provide the corresponding analysis.

[0078] The rule determination method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0079] For the convenience of description, the following unified description of each term involved in the embodiments of the present application is first given. (Unless otherwise specified, the following unified description of each term applies to each implementation method of the present application. In view of the fact that the individual term first appears later, the individual term will not be uniformly described here. The individual term will be described below when it first appears):

For example, if the first information includes: Application Server Address(es) = 100.1.1.1, offload function = MPTCP, RAT type = 5G Access, it means that the first communication device hopes that the second communication device will provide the access destination IP address as 100.1.1.1, use 5G access, and use the analysis results of the MPTCP offload function.

[0157] First rule: The first rule may be at least one of the following: PCC rule, ASSS rule, or MA PDU Session Control information. The first rule may also be a rule used by UE and / or UPF (e.g., ASSS rule), through which the allocation or distribution rule of downlink traffic and / or uplink traffic can be determined, that is, the allocation or distribution rule of uplink traffic in the first access mode or the second access mode, or the allocation or distribution rule of downlink traffic in the first access mode or the second access mode. The allocation or distribution rule here refers to the uplink or downlink traffic, which access mode is selected for transmission, or what proportion of uplink or downlink traffic is in the uplink or downlink traffic, and the traffic is transmitted or distributed under different access modes, or what diversion function is used, what diversion mode is used, what threshold is set, and used for uplink or downlink traffic transmission, etc. The first rule includes or indicates at least one of the following: diversion function, diversion mode, threshold, transmission mode, diversion mode indication.

[0158] In one implementation, the third information or the first rule indicates that the diversion mode is at least one of the following: Active-Standby mode, Smallest Delay mode, priority-based mode, load-balancing mode or redundant mode.

[0159] When the diversion mode in the third information or the first rule is an Active-Standby mode, the third information or the first rule includes or indicates which access mode in the first access mode or the second access mode is an active access mode and which access mode is a standby access mode;

[0160] When the offload mode in the third information or the first rule is the Smallest Delay mode, the third information or the first rule also includes or indicates an access method with the smallest delay, or the third information or the first rule indicates an access method with the highest priority; in one implementation, the third information or the first rule indicates that the first access method and / or the second access method are the access methods with the highest priority, or the third information or the first rule indicates that the first access method and / or the second access method are the access methods with the smallest delay;

[0161] When the diversion mode in the third information or the first rule is a priority mode (priority-based), the third information or the first rule also includes or indicates an access method with the smallest delay, or the third information or the first rule indicates an access method with the highest priority; in one implementation, the third information or the first rule may also include or indicate that the first access method and / or the second access method is the access with the highest priority;

[0162] When the diversion mode in the third information or the first rule is a load balancing mode, the third information or the first rule further indicates a diversion ratio, that is, the third information or the first rule indicates a traffic ratio (percentage of the SDF traffic that should be sent over 3GPP access and / or over non-3GPP access, SDF is a service data flow) borne by the first access method and / or the second access method;

[0163] When the diversion mode in the third information or the first rule is a redundant mode, the third information or the first rule further indicates a primary access, that is, the third information or the first rule further indicates which access mode of the first access mode and the second access mode is the primary access mode;

[0164] When the traffic distribution mode in the third information or the first rule is a load balancing mode, and / or when the third information or the first rule includes a threshold, the third information or the first rule further indicates whether to switch from the first access mode to the second access mode, or from the second access mode to the first access mode when the threshold is met;

[0165] When the diversion mode in the third information or the first rule is a priority diversion mode, and / or when the third information or the first rule contains a threshold, the third information or the first rule also indicates whether to switch from the first access mode to the second access mode, or from the second access mode to the first access mode when the threshold is met.

[0166] The second rule: The second communication device performs model building, reasoning training, etc. on the collected fourth information through the algorithm built into the second information, that is, performs AI artificial intelligence analysis to obtain the rule, and the second rule includes at least one of the following: PCC rule, ATSSS rule, and multi-access PDU session control information. The second rule can be regarded as a rule after intelligent analysis provided by the second communication device to the first communication device. After using this rule, the distribution of uplink and downlink traffic can be optimized to the greatest extent, for example, using the first access with better performance to transmit more uplink traffic, etc.

[0167] In an embodiment of the present application, a first communication device sends a first request to a second communication device, the first request includes first information, and then the second communication device collects relevant data of historical uplink traffic or downlink traffic based on the first information (i.e., fourth information), and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain second information, and the second information may include second rules and / or analysis results. Then, the second communication device sends the second information to the first communication device, the first communication device obtains third information based on the second information, and the second communication device sends the third information to the third communication device so that the third communication device determines the first rule. In this way, the present application clarifies that the first rule (i.e., ASSSS rule) is determined based on the analysis results provided by the second communication device (NWDAF). Moreover, because the analysis results provided by NWDAF are obtained by analyzing the relevant data of historical uplink traffic or downlink traffic, the accuracy of the first rule determined based on the analysis results provided by NWDAF is higher.

[0168] In one implementation, an ATSSS rule may be generated based on the third information. For example, the third communication device generates the ASSSS rule based on the third information.

[0169] In combination with the above unified description of each term, the first aspect of the embodiment of the present application provides a rule determination method, which is applied to a first communication device, see Figure 3 FIG. 1 is a flowchart of an implementation of a rule determination method provided in an embodiment of the present application. The method may include the following steps:

[0170] Step S310: the first communication device sends a first request to the second communication device, the first request includes first information, the first request is used to request second information, the second information is a result obtained through AI artificial intelligence analysis, and the second information is used for the first communication device to determine third information;

[0171] The third information is used to determine a first rule, where the first rule is used to determine a flow allocation or distribution method of uplink flow or downlink flow in the first access mode and / or the second access mode.

[0172] In an embodiment of the present application, a first communication device sends a first request to a second communication device, and the first request may be an analysis information request or an analysis subscription request. Specifically, analysis information request: used to directly request the second communication device to provide a corresponding analysis function. After receiving the analysis request, the second communication device executes the corresponding analysis function and feeds back the obtained second information to the first communication device. Analysis subscription request: used to subscribe to the analysis function of the second communication device. When the second communication device generates a new analysis result, it will automatically send or notify the first communication device of the analysis result, and automatically push the obtained second information to the first communication device.

[0173] In a specific implementation, the first communication device sends the first request to the second communication device via signaling, and similarly, the second communication device sends the second information to the first communication device via signaling. For example, taking the first communication device as a PCF and the second communication device as an NWDAF, Figure 4 The diagram illustrates the interaction process between the first communication device and the second communication device. PCF sends the first information in the form of signaling, for example, sending an analysis information request Nnwdaf_AnalyticsInfo_Request, or sending an analysis subscription request Nnwdaf_AnalyticsSubscription_Subscribe. After NWDAF performs the corresponding analysis function (for example, the observation service experience analysis function) according to the first request, it sends the obtained second information to SMF in the form of signaling, for example, the analysis request response Nnwdaf AnalyticsInfo, or the subscription notification Nnwdaf_AnalyticsSubscription_Notify.

[0174] In the embodiment of the present application, the first communication device tells the second communication device through the first information which parameters analysis results it wishes to obtain (for example, analysis results of diversion modes under different traffic distribution rules), and it may also wish to obtain analysis results after multiple parameter combinations, and then the second communication device collects relevant data according to the first information, and performs corresponding analysis functions to obtain the second information. Specifically, the first information includes at least one of the above-mentioned items A-1 to A-20.

[0175] The analysis identifier in item A-1 is used to identify different analysis functions in the second communication device, and different analysis functions correspond to different second information. By entering the corresponding analysis identifier in the first information, the second communication device can provide the corresponding analysis function. For example, if the analysis identifier is service experience, the analysis function provided by the second communication device is network data analysis related to the observed service experience; if the analysis identifier is load level information, the analysis function provided by the second communication device is network data analysis related to the slice load level. In one implementation, in an embodiment of the present application, the first communication device can generate intelligent ATSSS rules or PCC rules by requesting observed service experience related network data analytics; or the first communication device can request a new multiple access transmission experience related analysis to generate intelligent ATSSS rules or PCC rules.

[0176] The application identifier in item A-2 is used to identify the requested or subscribed application, and the application identifier in the first information can be one or more. For example, when it is necessary to determine the traffic allocation rules of a specified application on the UE, only the traffic-related data of the specified application can be analyzed, and the first information contains the application identifier of the specified application; when it is necessary to determine the traffic allocation rules of multiple applications on the UE, it is necessary to analyze the traffic-related parameters of multiple applications, and the first information contains the application identifiers of multiple applications. It can be understood that the application identifier can also be used to identify the application corresponding to the identifier and generate the corresponding analysis result, that is, only collect the data corresponding to the application, for example, the diversion mode, diversion ratio, diversion function, etc. used when transmitting the application data, and then give the corresponding analysis result.

[0177] A-3 Slice Identifier (Single Network Slice Selection Assistance Information, S-NSSAI) is used to identify the requested or subscribed network slice. By entering the corresponding slice identifier in the first information, it means that the first communication device hopes to obtain the analysis results when using the network slice identified by the slice identifier for data transmission or using the slice to establish a PDU session, and then the second communication device collects the traffic-related data in the network slice for analysis.

[0178] The area of ​​interest in item A-4 refers to a specific area (e.g., a specific cell). By inputting the area of ​​interest in the first information, it indicates requesting or subscribing to the analysis results in the area of ​​interest, and then the second communication device collects traffic-related data from the area of ​​interest. For example, when it is necessary to determine the traffic allocation rules for all UEs in a target area, the target area is the area of ​​interest, and the second communication device collects traffic-related data of UEs in the target area for analysis. If the terminal is not in the target area, the relevant data is not collected, and the obtained analysis results may only be for the terminals in the area of ​​interest.

[0179] Item A-5 Data Network Name (DNN) is used to request or subscribe to the analysis results corresponding to the terminal or application (traffic) accessing the data network. When you want to obtain the traffic distribution rules under a specific data network, for example, the analysis results of the terminal or PDU session or QoS flow accessing the DNN, then specify the data network name in the first information, and then the second communication device collects the traffic-related data of the data network for analysis.

[0180] Item A-6 Data Network Access Identifier (DNAI) is an identifier for the user plane to access one or more data networks. By inputting the data network access identifier in the first information, it indicates requesting or subscribing to the analysis result corresponding to the data network access identifier.

[0181] Item A-7 access method (Radio Access Technology Type, RAT Type) is used to request or subscribe to the analysis results corresponding to the specified access method. Access methods are divided into 3GPP access (for example, 5G access, LTE access, satellite access and other access methods) and non-3GPP access (for example, WLAN access, wifi access, Bluetooth access and other access methods). After the access method is specified, the second communication device will collect data using the access method (mainly some user experience or QoS indicators). For example, after using this access method to access a server, its uplink and downlink rates, uplink and downlink bandwidths, uplink and downlink packet loss rates, etc. The second communication device can also collect the user experience or service experience that can be achieved after using the access method. In one embodiment, the access method may be the type of access network where the terminal resides.

[0182] The access frequency in item A-8 refers to the access frequency corresponding to the access method. The traffic transmission performance is different under different access frequencies. When you want to obtain the traffic transmission performance under a certain access frequency, enter the access frequency in the first information, and then the second communication device collects the traffic-related data under the access frequency for analysis. The access frequency is mainly when the access method is determined. Different frequencies may cause different user experiences or service experiences in the access method.

[0183] The IP address of item A-9 refers to the destination IP address of the application server accessed by the UE. By entering the destination IP address in the first information, it indicates a request or subscription to access the analysis result corresponding to the target IP address. When it is necessary to determine the traffic distribution rules or traffic transmission performance of a certain application server, the destination IP address of the application server is entered in the first information so that the second communication device can collect the traffic-related data of the application server for analysis. For example, under 5G access, the performance of accessing the application server in various modes (e.g., diversion function, diversion ratio, diversion mode, threshold setting, etc.) is analyzed.

[0184] The access type in item A-10 is used to request or subscribe to the analysis results corresponding to the UE access type. The access type is divided into 3GPP access (for example, 5G access, LTE access, satellite access, etc.) and non-3GPP access (for example, WLAN access, wifi access, Bluetooth access, etc.). The access type or access type here refers to the type of PDU session established by the terminal. In the embodiment of the present application, Access type can be translated into access type or access type.

[0185] The address of the public land mobile network (Public Land Mobile Network ID, PLMN ID) in item A-11 is used to identify the target public land mobile network. By entering the address of the public land mobile network in the first information, it indicates a request or subscription to the analysis result corresponding to the terminal or established session within the operator corresponding to the public land mobile network.

[0186] The terminal identification of item A-12 is used to identify different UEs, and the terminal identification in the first information can be one or more. For example, when it is necessary to determine the traffic allocation rules of a specific UE, only the traffic-related data of the specific UE can be collected or output for analysis, and at this time, the first information only contains the terminal identification of the specific UE; when it is necessary to determine the traffic allocation rules of multiple UEs, it is necessary to collect or analyze the traffic-related data of multiple UEs, and at this time, the first information contains the terminal identification of multiple UEs.

[0187] The application descriptor in item A-13 is used to identify which application on the UE sends the traffic, and analyze the communication indicators or service experience that can be achieved when the traffic is sent from this application. For a certain application of the UE, the performance corresponding to the traffic sent by the application is analyzed by specifying the corresponding application descriptor. For example, when the traffic is sent from the application, what kind of traffic distribution rules can be used to achieve what kind of communication indicators or service experience.

[0188] A-14 Diversion Function, A-15 Diversion Mode, A-16 Traffic Type, and A-17 Transmission Mode refer to various indicators under the traffic allocation rule. By analyzing various indicators of the traffic allocation rule, the performance analysis results of the traffic allocation rule are obtained. In specific implementation, according to the analysis results of various indicators of the traffic allocation rule, the indicators of the traffic allocation rule are adjusted to obtain a traffic allocation rule with better performance. For example, the diversion function is adjusted to MPTCP mode or MPQUIC mode.

[0189] In one implementation manner, the traffic allocation rules described in the embodiments of the present application can also be translated or understood as traffic distribution rules, or traffic routing rules, or traffic diversion rules. In short, they all represent how the upstream or downstream traffic is transmitted, distributed, routed, and delivered under two different access methods. In another implementation manner, the two access methods can also be expanded into multiple access methods. The transmission, distribution, routing, and delivery under two different access methods here are actually used to design or specify which access method to select for transmission of the upstream and downstream traffic, which diversion function to select for transmission, which diversion mode to select for transmission, or what type of traffic to transmit (TCP or UDP), or what percentage of the traffic is transmitted using the first access method, and what percentage of the traffic is transmitted using the second access method, etc.

[0190] In the embodiment of the present application, the analysis result includes statistical results (statistics) or prediction results (prediction).

[0191] In the embodiment of the present application, the second information may provide statistical results or prediction results, and the statistical results include:

[0192] The MA PDU session experience statistics result includes at least one of the following corresponding service experiences, or at least one of the following corresponding service experiences after combination, such as:

[0193] The service experience corresponding to using different diversion functions;

[0194] The service experience corresponding to different transmission modes;

[0195] The service experience corresponding to different diversion modes;

[0196] The service experience corresponding to different RAT types;

[0197] Achieve service experience corresponding to different RTTs;

[0198] Achieve service experience corresponding to different packet loss rates (can be end-to-end packet loss rate, or packet loss rate on the base station side or UPF side).

[0199] Alternatively, when the RAT type is fixed, the experience that can be achieved by using different offload functions, transmission modes, offload modes, etc., such as the service experience corresponding to the RAT type or the service experience of the entire MAPDU session.

[0200] For example, when the first access is 5G access, the overall MA PDU session service experience can be achieved after using the MPTCP function and the minimum delay diversion mode.

[0201] Therefore, it can be seen that in the embodiment of the present application, the second communication device can not only provide the service experience or performance of the entire MA PDU session after using the above parameters, but also provide the service experience of using the diversion mode alone.

[0202] In the embodiment of the present application, the second information may provide statistical results or prediction results, and the prediction results include:

[0203] The MA PDU session experience prediction result includes at least one of the following corresponding service experiences, or at least one of the following corresponding service experience prediction results after a combination of the following, such as:

[0204] Use the service experience prediction results corresponding to different diversion functions;

[0205] Use the service experience prediction results corresponding to different transmission modes;

[0206] Use the service experience prediction results corresponding to different diversion modes;

[0207] Use the service experience prediction results corresponding to different RAT types;

[0208] Achieve service experience prediction results corresponding to different RTTs;

[0209] The service experience prediction results corresponding to different packet loss rates are achieved (it can be the end-to-end packet loss rate, or the packet loss rate on the base station side or UPF side).

[0210] Alternatively, when the RAT type is fixed, the experience prediction results that can be achieved by using different offload functions, transmission modes, offload modes, etc., such as the service experience corresponding to the RAT type or the service experience prediction result of the entire MA PDU session.

[0211] For example, when the first access is 5G access, the overall MA PDU session service experience prediction result can be achieved after using the MPTCP function and the minimum delay diversion mode.

[0212] Therefore, it can be seen that in the embodiment of the present application, the second communication device can not only provide the service experience or performance prediction results of the entire MA PDU session after using the above parameters, but also provide the service experience prediction results of using the diversion mode alone.

[0213] In the embodiment of the present application, the analysis result output by the second communication device may be a service experience, various communication indicators, a MOS value, a user experience, or a QoS indicator parameter (e.g., uplink and downlink rates, uplink and downlink packet loss rates, etc.). In other words, the analysis result may be measured by using the experience as an indicator, or may be measured by using various communication indicators from a communication perspective.

[0214] In addition, the second information output by the second communication device can also be given as an analysis result of accessing a specific destination IP address (Application server instance address), or an analysis target area of ​​the analysis result (that is, the analysis result is generated based on data within what time period), or the analysis result is obtained by analyzing which terminals and which locations the analysis result is collected from.

[0215] The service experience in the embodiment of the present application can be a MOS value, or various communication indicators, or a MOS value, or a user experience, or a QoS indicator parameter (for example, uplink and downlink rates, uplink and downlink packet loss rates, etc.). In other words, the service experience here can be measured by the experience as an indicator (giving an experience score), or it can be measured by giving various communication indicators from the communication perspective.

[0216] In a specific implementation, after the second communication device receives the first request, the second communication device collects fourth information according to the first information, and generates the second information according to the fourth information. The fourth information includes data collected according to at least one of items B-1 to B-39.

[0217] In the embodiment of the present application, the second communication device needs to collect enough traffic-related data (i.e., the fourth information) to provide the second information based on its own AI artificial intelligence analysis function, for example, to collect corresponding data under different diversion functions and diversion modes. Figure 5 As shown, after receiving the first request, the second communication device (such as NWDAF) collects fourth information from the network element function (NEF), application function (AF), network function (NF), UPF and UE according to the first information in the first request, where NEF refers to network element functions such as SMF and PCF, and generates second information based on the fourth information and sends it to the first communication device.

[0218] The method for the second communication device to collect the fourth information according to the first information is as follows: the second communication device may determine what type of fourth information to collect according to the content of the first information:

[0219] When the first information includes a traffic diversion function, the second communication device needs to collect data related to the service experience after using the traffic diversion function. The second communication device needs to collect service experience, user experience, or communication indicators (including QoS indicators such as uplink and downlink packet loss rate on the RAN side, uplink and downlink packet delay on the RAN side, RTT, uplink and downlink packet loss rate, etc.) corresponding to the traffic diversion function;

[0220] When there is a diversion mode in the first information, the second communication device needs to collect data related to the service experience after using the diversion mode. The second communication device needs to collect the service experience, user experience, or communication indicators (including uplink and downlink packet loss rate on the RAN side, uplink and downlink packet delay on the RAN side, RTT, uplink and downlink packet loss rate and other QoS indicators) corresponding to the diversion mode, etc.;

[0221] When the first information includes an access mode (RAT type), the second communication device shall collect data related to the service experience after using the access mode (for example, a PDU session using the access mode), and the second communication device shall collect service experience, user experience, or communication indicators corresponding to the access mode (including QoS indicators such as uplink and downlink packet loss rate on the RAN side, uplink and downlink packet delay on the RAN side, RTT, uplink and downlink packet loss rate, etc.);

[0222] In the embodiment of the present application, the access mode is equivalent to RAT type (radio access technology type).

[0230] When the first information contains an application descriptor, the second communication device shall collect data related to the service experience of the traffic sent from the application corresponding to the application descriptor (for example, the traffic sent from the application and then carried by the PDU session or QoS flow).

[0269] In a specific implementation, when the second rule is a PCC rule, the PCC rule is sent to a third communication device (e.g., SMF) so that the third communication device generates a traffic distribution rule (e.g., ATSSS rule) according to the PCC rule. When the second rule is an ATSSS rule, the ATSSS rule can be directly provided to the UE or UPF for use, and when the second rule is multi-access PDU session control information, the PDU session control information is sent to a third communication device (e.g., SMF) so that the third communication device generates a traffic distribution rule according to the PDU session control information.

[0270] In addition, in an embodiment of the present application, after the SMF third communication device receives the third information sent by the first communication device, it can also send a first request to the second communication device, where the first request includes first information, and the first request is used to request second information. The second information is used for the third communication device to determine a first rule, and the first rule is used to determine the traffic allocation or distribution method of the uplink traffic or the downlink traffic under the first access method and / or the second access method.

[0271] In an embodiment of the present application, a third communication device sends a first request to a second communication device, and the first request may be an analysis information request or an analysis subscription request. Specifically, analysis information request: used to directly request the second communication device to provide a corresponding analysis function. After receiving the analysis request, the second communication device performs the corresponding analysis function and feeds back the obtained second information to the third communication device. Analysis subscription request: used to subscribe to the analysis function of the second communication device. When the second communication device generates a new analysis result, it will automatically send or notify the third communication device of the analysis result, and automatically push the obtained second information to the third communication device.

[0272] In one implementation, in the embodiment of the present application, the third communication device may also request the second communication device to provide an analysis result, and then the third communication device generates a first rule based on the second information, for example, a PCC rule or an ATSSS rule after intelligent analysis. In this case, the third communication device may be an SMF. Alternatively, after receiving the PCC rule of the first communication device, the third communication device may request the second information of the second communication device and then generate the first rule.

[0273] In a specific implementation manner, the second information is used to indicate at least one of the following:

[0293] Item D-19: The corresponding analysis result when the PDU session meets the end-to-end uplink or downlink packet loss rate E2E UL / DL packet loss rate.

[0294] In the embodiment of the present application, the second communication device obtains at least one of the second rule and the analysis result by performing AI artificial intelligence analysis on the fourth information. The second rule is a rule related to the traffic allocation rule, which can be used to determine the allocation rule of the uplink traffic in the first access mode or the second access mode, and determine the allocation rule of the downlink traffic in the first access mode or the second access mode.

[0295] The second information includes at least one of the following: a second rule and an analysis result. The analysis result may include a statistical result and / or a prediction result. Specifically, the statistical result is a statistical value obtained by the second communication device by counting the relevant data of the historical uplink traffic or downlink traffic; the prediction result refers to the prediction value given by the second communication device based on the relevant data of the historical uplink traffic or downlink traffic, and the prediction value is used to characterize the possible results in the future. In the specific implementation, the second communication device first counts the collected fourth information to obtain the statistical results of items D-1 to D-21, and then performs prediction processing based on the statistical results to obtain the prediction results of each item.

[0296] Specifically, the D-1 terminal identifier is used to identify whether the analysis result is applicable to multiple UEs or to one UE, or whether the analysis result is generated after data collection from one terminal or multiple terminals. In a specific implementation, if the second communication device analyzes the traffic-related data collected from multiple UEs to obtain a corresponding analysis result, the analysis result is applicable to multiple UEs. At this time, the traffic allocation rule obtained based on the analysis result is suitable for multiple UEs, that is, the traffic allocation rule is suitable for multiple UEs, and is a traffic allocation rule for one or more specific applications in a specific location and time period. If the second communication device analyzes the traffic-related data collected from a UE to obtain a corresponding analysis result, the analysis result is applicable to one UE. At this time, the traffic allocation rule obtained based on the analysis result is suitable for one UE, that is, the traffic allocation rule is suitable for one UE, and is a traffic allocation rule for a specific application in a specific location and time period.

[0297] The data network name in item D-2 is used to identify which data network the analysis result applies to. In specific implementation, if the second communication device collects traffic-related data under a certain data network for analysis and obtains corresponding analysis results, then the analysis results apply to the data network. Similarly, if the second communication device collects traffic-related data under multiple data networks for analysis and obtains corresponding analysis results, then the analysis results apply to multiple data networks.

[0298] D-3 spatial validity is used to identify the location to which the analysis result of the MA PDU session applies. The location here can be the terminal location, the location of the server accessed by the MA PDU session, or the location where the session is established.

[0299] Item D-4, terminal location, is used to identify the UE location to which the analysis result applies. For example, the second communication device performs analysis based on the traffic-related data of the UE collected by cell A, and the obtained analysis result applies to the UE of cell A.

[0300] The D-5 time slot entry refers to the time range in the future that the obtained analysis result corresponds to, the D-6 start time refers to the start time corresponding to the analysis result, and the D-7 duration refers to the duration corresponding to the analysis result. For example, if the analysis result is an analysis result at 9-10 o'clock tomorrow, the time range corresponding to the analysis result is 9-10 o'clock, the start time corresponding to the analysis result is 9 o'clock, and the duration corresponding to the analysis result is 2 hours. The time corresponding to the analysis result here can also indicate the time corresponding to the prediction result, that is, which time period in the future the prediction result applies to. In the embodiment of the present application, the time range Time slot entry can also be expressed as a time period, that is, the time period starting within the Analytics target period (Time slot start within the Analytics targetperiod).

[0301] The IP address of the D-8 project refers to the destination IP address, FQDN, or APP ID used to access the application server according to the analysis results. In specific implementation, it is necessary to give the traffic distribution rules or performance of a certain application server according to the analysis results, so that the performance of this destination IP can be accessed.

[0302] The application descriptor in item D-9 is used to identify the traffic sent from the application on the UE to which the analysis result applies.

[0303] Item D-10, the multi-access PDU session identifier, is used to identify that the analysis result is applicable to the multi-access PDU session.

[0304] D-11 Access method is used to identify which access method the analysis result is applicable to. Different access methods are used in different traffic diversion modes. The access method can be 3DPP access or non-3GPP access. Different access methods correspond to different traffic transmission performance, that is, different analysis results.

[0305] Items D-12 to D-17 are used to identify the analysis results of various indicators. Different indicator values ​​of various indicators of the traffic distribution rule affect the traffic transmission performance. By analyzing the performance of each indicator, the performance analysis results of each indicator are obtained. Then, the indicators of the traffic distribution rule can be adjusted according to the analysis results of each indicator of the traffic distribution rule to obtain the traffic distribution rule.

[0306] Items D-18 and D-19 are used to identify which traffic transmission performance parameter the analysis result applies to. The traffic transmission performance parameters under different traffic allocation rules may be different.

[0307] In a specific implementation, after step S310, the method further includes steps S320 and S330:

[0308] Step S320: The first communication device receives the second information.

[0309] Step S330: The first communication device determines the third information according to the second information.

[0310] In the embodiment of the present application, after receiving the second information provided by the second communication device, the first communication device generates the third information based on the second information. The third information is used to determine the traffic allocation rule, that is, to determine the allocation rule of the uplink traffic in the first access mode or the second access mode, and to determine the allocation rule of the downlink traffic in the first access mode or the second access mode.

[0311] In a specific implementation, the third information includes at least one of the following:

[0312] Item E-1: PCC rules;

[0313] E-2: ATSSS rules;

[0314] Item E-3: MA PDU Session Control information.

[0315] In a specific implementation, when the third information is the PCC rule of item E-1, the PCC rule is sent to a third communication device (e.g., SMF) so that the third communication device generates a traffic distribution rule according to the PCC rule. When the third information is the ATSSS rule of item E-2, the ASSSS rule can be directly provided to the UE or UPF for use. When the third information is the multi-access PDU session control information of item E-3, the PDU session control information is sent to a third communication device (e.g., SMF) so that the third communication device generates a traffic distribution rule according to the PDU session control information.

[0316] In the embodiment of the present application, after the first communication device receives the second information, the third information, that is, the PCC rule or the ATSSS rule, can be determined or generated according to the second information. The first communication device determines each item under the PCC rule or the ATSSS rule according to the analysis result indicated in the second information.

[0317] For example, if the second information gives analysis results corresponding to multiple diversion functions, the first communication device selects the diversion function with the best performance or the best service experience as the diversion function in the third information (for example, as the diversion function of the PCC rule or the ATSSS rule); for another example, if the second information gives analysis results corresponding to multiple transmission modes, the first communication device selects the transmission function with the best performance or the best service experience as the transmission function in the third information (for example, as the transmission function of the PCC rule or the ATSSS rule).

[0318] It can be understood that the first communication device determines the third information based on the second information, mainly based on the analysis result of at least one item in the second information. When the analysis result shows that the service experience, user experience, or performance is the best, the item is selected as the diversion mode in the third information, etc.

[0319] It can also be understood that the first communication device can compare the performance of various different MA PDU session parameter combinations based on the analysis results of the multiple parameter combinations given in the second information, and then select the one with the best performance or the best service experience as the MA PDU session parameter, or as a parameter in the PCC rule or ATSSS rule. For example, the first communication device, based on the second information, simultaneously obtains the analysis results of: MPTCP diversion function + load balancing diversion mode, and MPQUIC diversion function + load balancing diversion mode. The results show that the MPTCP diversion function + load balancing diversion mode has a better user experience. Then the first communication device can directly set the diversion function in the third information to MPTCP, and the diversion mode to the load balancing mode.

[0320] In the embodiments of the present application, the so-called best performance, better performance, or best analysis result refers to a good service experience, or a larger MOS value, a better user experience, or at least one communication indicator is better (for example, higher uplink and downlink rates, lower packet loss rate, lower uplink and downlink transmission delay, lower uplink and downlink packet transmission delay, etc.). The best analysis result also refers to a good service experience indicated by the analysis result, or a larger MOS value, a better user experience, or at least one communication indicator is better (for example, higher uplink and downlink rates, lower packet loss rate, lower uplink and downlink transmission delay, lower uplink and downlink packet transmission delay, etc.).

[0321] In a specific implementation manner, any item of the third information specifically includes at least one of the following:

[0322] Item F-1: Steering Functionality;

[0323] Item F-2: Steering Mode;

[0324] Item F-3: Threshold;

[0325] F-4: Transport Mode;

[0326] Item F-5: Diverter mode indication.

[0327] In the embodiment of the present application, items F-1 to F-5 are indicators of the traffic distribution rule, and based on the contents of items F-1 to F-5, it is possible to know how the traffic is transmitted. Each of items E-1 to E-3 in the third information contains the contents of items F-1 to F-5.

[0328] In a specific implementation manner, the first communication device determines the third information according to the second information, including at least one of the following:

[0334] Item G-6: The first communication device determines the diversion ratio with the best analysis result as the diversion ratio in the third information based on the analysis results corresponding to different diversion ratios in the second information, or determines it as the diversion ratio with the highest priority in the third information, where the diversion ratio is the diversion ratio of the uplink traffic or the downlink traffic in the first access mode or the second access mode.

[0335] The best analysis result here, as mentioned above, can be the one that indicates the best service experience, or the largest MOS value, the best user experience, or at least the best communication indicator (for example, higher uplink and downlink rates, lower packet loss rate, lower uplink and downlink transmission delay, lower uplink and downlink packet transmission delay, etc.).

[0336] In an embodiment of the present application, the third information is determined based on the analysis results (i.e., the second information) provided by the second communication device. Specifically, for each indicator included in each rule in the third information (i.e., PCC rule, ATSSS rule, and multi-access PDU session control information), each indicator is adjusted according to the performance corresponding to each indicator, thereby obtaining each rule in the third information.

[0337] Specifically, for item G-1, the first access method or the second access method can be 3GPP access or non-3GPP access. Different access methods have different traffic transmission performance. The analysis results of the two access methods are compared, and the access method with the best analysis result is selected as the access method in the third information, that is, the access method of each rule in the third information. For example, determine the access method for the ATSSS rule.

[0338] For item G-2, the diversion modes include: active-standby mode, minimum delay, load balancing, priority mode and / or redundant transmission. According to the analysis results corresponding to the above diversion modes, the diversion mode with the best analysis result is selected as the diversion mode in the third information. For example, if the analysis result of the active-standby mode has the best performance, the active-standby mode is selected as the diversion mode in the third information.

[0339] For item G-3, the diversion functions include MPTCP, MPQUIC and / or ASSSS-LL. According to the analysis results corresponding to the above diversion functions, the diversion function with the best analysis result is selected as the diversion mode of each rule in the third information. For example, if the analysis result of MPTCP has the best performance, the MPTCP is selected as the diversion function in the third information.

[0340] For item G-4, the transmission mode is applicable to the transmission mode under the MPQUIC offloading function, including datagram mode 1, datagram mode 2 and / or stream mode. According to the analysis results corresponding to the above transmission modes, the transmission mode with the best analysis result is selected as the transmission mode of each rule in the third information. For example, if the analysis result of datagram mode 1 has the best performance, datagram mode 1 is selected as the transmission mode in the third information.

[0341] For item G-5, the threshold includes a maximum RTT threshold and / or a maximum packet loss rate threshold, and the threshold is used to determine when to enable the backup path (i.e., for switching between the first access mode and the second access mode), and the threshold is used only in the two traffic diversion modes of load balancing and redundant transmission. By comparing the analysis results corresponding to different thresholds, the threshold with the best analysis result is determined as the threshold in the third information.

[0342] For item G-6, different diversion ratios have different traffic transmission performances. By comparing the analysis results corresponding to different traffic ratios, the diversion ratio with the best analysis result is determined as the diversion ratio in the third information.

[0343] In one implementation, the first communication device directly sends the second rule in the second information as the first rule to the third communication device. For example, if the second information provides an intelligently generated PCC rule, the first communication device directly sends it as the PCC rule to the third communication device SMF.

[0344] Or in another implementation manner, the first communication device determines or generates the first rule according to the analysis result in the second information (the analysis result corresponding to at least one item of the first information). The method is as follows:

[0345] First, the second information will give the analysis result corresponding to at least one item in the first information, for example: give the analysis result corresponding to at least one diversion function Steering Functionality; give the analysis result corresponding to at least one diversion mode SteeringMode; give the analysis result corresponding to at least one traffic type Traffic type; give the analysis result corresponding to at least one transmission mode Transport Mode.

[0346] Then, the first communication device can determine the diversion mode, diversion function, etc. in the first rule based on the analysis result. For example, the second information gives the analysis results corresponding to two diversion functions: the analysis result corresponding to the MPTCP diversion function and the analysis result corresponding to MPQUIC. The analysis results show that after using MPTCP, its performance is better (the better performance here can refer to the high MOS score after using MPTCP, or the good communication performance or indicators after using the diversion function, such as a higher uplink rate, or a better service experience, etc.). Then, the first communication device will select MPTCP as the diversion function, and then, when generating the first rule, set the diversion function under the first rule to MPTCP.

[0347] For another example, the second information gives the analysis results corresponding to two diversion modes: the analysis results corresponding to the active-standby mode and the analysis results corresponding to the minimum delay mode. The analysis results show that the performance is better after using the active-standby mode (the better performance here can refer to the high MOS score after using the active-standby mode, or the good communication performance or indicators after using the diversion function, such as a higher uplink rate, or a better service experience, etc.). Then, the first communication device will select the active-standby mode as the diversion mode, and then, when generating the first rule, set the diversion mode under the first rule to the active-standby mode.

[0348] It can be seen that the second information received by the first communication device is actually the analysis result corresponding to at least one item in the received first information. Each item in the first information also includes many lower-level concepts (for example, under the diversion function, it includes MPTCP, MPQUIC, ATSSS-LL, etc.). The first communication device selects the item with the best analysis result as the corresponding item in the first rule based on the analysis result corresponding to at least one item in the first information. The following is an example:

[0349] First, the second information will give an analysis result corresponding to at least one item in the first information, for example: an analysis result corresponding to at least one Steering Functionality; an analysis result corresponding to at least one Steering Mode; an analysis result corresponding to at least one Traffic type; and an analysis result corresponding to at least one Transport Mode.

[0350] The first rule also includes a diversion function, a diversion mode, a traffic type, a transmission mode, etc. That is, the first rule is also composed of at least one first information. Therefore, at least one first information in the first rule can be determined according to the analysis result corresponding to at least one first information.

[0351] The first communication device selects a diversion function with the best performance among the diversion functions Steering Functionality as the diversion function under the first rule; and the second information provides analysis results corresponding to one or more diversion functions;

[0352] The first communication device selects a diversion mode with the best performance in the diversion mode Steering Mode as the diversion mode under the first rule; and the second information provides analysis results corresponding to one or more diversion modes;

[0353] The first communication device selects a traffic type with the best performance among the traffic types Traffic type as the traffic type under the first rule; and the second information provides analysis results corresponding to one or more traffic types;

[0354] The first communication device selects a transmission mode with the best performance among the transmission modes Transport Mode as the transmission mode under the first rule; and the second information provides analysis results corresponding to one or more transmission modes.

[0355] The best performance here, as mentioned above, can be a high MOS score after use, or good communication performance or indicators after use, such as a higher uplink rate, or a better service experience, etc.

[0356] The first communication device determines according to the second information, and sends the third information to the third communication device, so that the third communication device generates the first rule, and also includes the following method:

[0357] The second information received by the first communication device is the analysis result of at least one combination of the first information. Then, the first communication device can compare different combinations of the first information, and then determine the content under the first rule (the content under the first rule also includes at least one first information), and select the parameters corresponding to at least one combination of the first information with the best performance as the parameters under the first rule. It can be understood that:

[0358] The first communication device receives the following content from the second communication device:

[0359] 5G access, MPTCP offload function, offload mode active / standby mode, the corresponding MOS score is 80 points;

[0360] 5G access, MPTCP offload function, offload mode redundant transmission mode, the corresponding MOS score is 75 points;

[0361] It can be seen that when the access mode is 5G access and the diversion function is set to MPTCP, selecting the redundant transmission mode at this time can achieve better transmission or data distribution performance. Therefore, the first communication device determines the diversion mode of the redundant transmission mode as the diversion mode in the first rule.

[0362] It can be understood that the first communication device can also determine how to set the parameters in the first rule based on a combination of at least one item of different first information. The judgment criteria are still based on the analysis results, and the parameters in the first rule are screened or determined based on the best performance reflected by the analysis results (the parameters of the first rule here are also at least one item of first information).

[0363] Another example is as follows:

[0364] The first communication device receives the following content from the second communication device:

[0365] 5G access, MPTCP offload function, offload mode active / standby mode, offload ratio, 3GPP access 50%, non-3GPP access 50%, the corresponding MOS score is 60 points;

[0366] 5G access, MPTCP offload function, offload mode active / standby mode, offload ratio, 3GPP access 20%, non-3GPP access 80%, the corresponding MOS score is 80 points.

[0367] It can be seen that when the access mode is 5G access and the diversion function is set to MPTCP, the active-standby mode, at this time the diversion ratio is selected as "3GPP access 20%, non-3GPP access 80%" to achieve better transmission or data distribution performance. Therefore, the first communication device sets the diversion ratio to "3GPP access 20%, non-3GPP access 80%", which is determined as the diversion ratio in the first rule.

[0368] Another example is as follows:

[0369] The first communication device selects, according to the analysis result corresponding to at least one access method in the second information, an access method that is best indicated by the analysis result as at least one of the following:

[0370] When the traffic distribution mode is in active / standby mode, it acts as the active access in the active / standby mode.

[0371] When the offload mode is the priority mode, it is used as a high-priority access mode under the Priority-based mode;

[0372] When the traffic distribution mode is load balancing mode, this priority level bears a higher proportion of traffic in load balancing mode;

[0373] When the traffic distribution mode is redundant, it serves as the primary access in the redundant transmission mode.

[0374] For example, in the second information, the analysis results corresponding to 5G access and / or non-3GPP access are indicated at the same time. If the analysis result of 5G access shows better (for example, better user experience, better service experience, high MOS value, etc.), then:

[0375] Use 5G access as the primary access in the active-standby mode, and non-3GPP access as the standby access;

[0376] Set the traffic diversion mode to Priority-based, and then use 5G as a high-priority access mode, or 5G access has a higher priority;

[0377] In load balancing mode, 5G access carries more offload traffic or offload ratio than non-3GPP access. For example, 5G access can bear 80% of the traffic and non-3GPP can bear 20% of the traffic. In other words, the analysis results show that the better access method can carry more traffic transmission;

[0378] In the redundant transmission diversion mode, 5G access is used as the primary access for data transmission.

[0379] In a specific implementation, when the second information includes a second rule, the method further includes:

[0380] The first communication device receives the second information;

[0381] The first communication device determines the second rule in the second information as the third information.

[0382] In the embodiment of the present application, the second rule is a rule related to the traffic allocation rule provided by the second communication device, and the rule can be directly used to determine the allocation rule of the uplink traffic in the first access mode or the second access mode, and / or determine the allocation rule of the downlink traffic in the first access mode or the second access mode. At this time, the second rule is directly used as the third information.

[0383] In a specific implementation manner, after the first communication device determines the third information according to the second information, step S330 further includes step S340:

[0384] S340: The first communication device sends the third information to a third communication device, where the third information is used by the third communication device to generate a first rule;

[0385] The first rule includes at least one of the following:

[0386] H-1: Steering Functionality;

[0387] H-2: Steering Mode;

[0388] Item H-3: Threshold;

[0389] H-4: Transport Mode;

[0390] Item H-5: Diversion mode indication.

[0391] In an embodiment of the present application, the first rule is the rule used by the UE and the UPF, namely, the ASSS rule. Based on the various indicators contained in the first rule, it is possible to determine how the UE's uplink traffic is transmitted in the first access mode or the second access mode, and how the UPF's downlink traffic is transmitted in the first access mode or the second access mode.

[0392] In a specific implementation, when the third information is a PCC rule, the third communication device generates an ASSS rule according to the PCC rule, and sends the ASSSS rule to the UE or UPF for use. When the third information is an ATSSS rule, the third communication device directly sends the ASSSS rule to the UE or UPF for use. When the third information is multi-access PDU session control information, the third communication device generates an ASSS rule according to the multi-access PDU session control information, and sends the ASSSS rule to the UE or UPF for use.

[0393] The rule determination method provided in the embodiment of the present application can be used in the following five scenarios, but is not limited to these five scenarios.

[0394] Scenario 1: The first communication device provides a traffic allocation rule (i.e., a first rule) for a specific UE according to the second information provided by the second communication device. At this time, this traffic allocation rule is suitable for a specific UE, a traffic allocation rule for a specific application in a specific location and time period, and this traffic allocation rule has a per UE characteristic.

[0395] In a specific implementation, the first communication device sends a first request to the second communication device, the first request includes first information, the first information includes the terminal identification of the specific UE, and then the second communication device collects the relevant data of the historical uplink traffic of the UE based on the first information (i.e., the fourth information), and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain the second information, and the second information includes a second rule for determining the UE traffic allocation rule (e.g., ATSSS rule, PCC rule, etc.). Then, the second communication device sends the second information to the first communication device, the first communication device obtains the third information based on the second information, and sends the third information to the third communication device, so that the third communication device determines the first rule (i.e., the first rule). In this way, in this scenario, the traffic allocation rule of the specific UE is determined according to the second rule provided by the second communication device.

[0396] Scenario 2: The first communication device provides traffic allocation rules after intelligent analysis for multiple UEs based on the second information provided by the second communication device. At this time, the traffic allocation rules are suitable for multiple terminals, within a specific location and time period, and for one or more specific applications.

[0397] In a specific implementation, the first communication device sends a first request to the second communication device, the first request includes first information, the first information includes the terminal identification of the multiple UEs, and then the second communication device collects the relevant data of the historical uplink traffic of the multiple UEs based on the first information (i.e., the fourth information), and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain the second information, the second information includes the analysis results of the parameters related to the traffic transmission of multiple UEs (for example, the analysis results of different access methods of the UE, the analysis results of different diversion modes, etc.). Then, the second communication device sends the second information to the first communication device, the first communication device obtains the third information based on the second information, and sends the third information to the third communication device, so that the third communication device determines the first rule (i.e., the traffic allocation rule for multiple UEs). In this way, in this scenario, the traffic allocation rule for multiple UEs is determined according to the analysis results provided by the second communication device.

[0398] Scenario 3: The first communication device adjusts relevant indicators of a traffic distribution rule according to the second information provided by the second communication device.

[0399] In a specific implementation, the first communication device sends a first request to the second communication device, the first request includes first information, the first information includes various indicators of the traffic distribution rule (for example, diversion function, diversion mode, traffic type and transmission mode, etc.), and then the second communication device collects the traffic-related parameters of various indicators of the traffic distribution rule based on the first information (i.e., the fourth information), and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain the second information, the second information includes the analysis results of various indicators of the traffic distribution rule (for example, the analysis results of the diversion function). Then, the second communication device sends the second information to the first communication device, and the first communication device adjusts the various indicators of the traffic distribution rule based on the analysis results of the indicators of the second information (for example, adjusts the diversion function, diversion ratio, access method, etc. of the traffic distribution rule), and finally obtains a traffic distribution rule with better performance.

[0400] Scenario 4: The first communication device provides a suitable traffic distribution rule or performance for accessing a specific application server according to the second information provided by the second communication device.

[0401] In a specific implementation, the first communication device sends a first request to the second communication device, the first request includes first information, the first information includes the target IP address, and then the second communication device collects the traffic-related parameters of various indicators of the traffic distribution rule based on the first information (i.e., the fourth information), and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain the second information, the second information includes the performance analysis results corresponding to the target IP address (for example, how is the performance in various modes when accessing this server address under different access methods). Then, the second communication device sends the second information to the first communication device, and the first communication device determines the appropriate traffic distribution rule suitable for the specific application server based on the performance analysis results corresponding to the destination IP address in the second information.

[0402] Scenario 5: The first communication device formulates a traffic allocation rule specifically for a specific application on the UE according to the second information provided by the second communication device, specifically, what is the traffic sent by the application and what traffic allocation rule is used for transmission.

[0403] In a specific implementation, the first communication device sends a first request to the second communication device, the first request includes the first information, the first information includes the specific application identifier, and then the second communication device collects the flow-related data (i.e., the fourth information) of the application corresponding to the application identifier based on the first information, and analyzes the fourth information based on its own AI artificial intelligence analysis function to obtain the second information, the second information includes the analysis result corresponding to the specific application. Then, the second communication device sends the second information to the first communication device, and the first communication device determines the flow distribution rule suitable for the specific application based on the analysis result corresponding to the specific application in the second information.

[0404] In a second aspect, a rule determination method is provided, the method being applied to a second communication device, see Figure 6 FIG. 1 is a flowchart of an implementation method of a rule determination method provided in an embodiment of the present application, and the method includes at least the following steps:

[0406] The third information is used to determine a first rule, where the first rule is used to determine a flow allocation or distribution method of uplink flow or downlink flow in the first access mode and / or the second access mode.

[0407] It can be seen from the above steps that in an embodiment of the present application, the first communication device sends a first request to the second communication device to request the second information from the second communication device, and then determines the third information based on the second information provided by the second communication device, and the third information is used to determine the first rule, and the first rule is used to determine the traffic allocation or distribution method of the uplink traffic or downlink traffic under the first access method and / or the second access method. In this way, the first communication device determines the allocation rule using the second information provided by the second communication device, that is, the first communication device determines the allocation rule with reference to the second information provided by the second communication device. Because the second information is the result obtained through AI artificial intelligence analysis, the accuracy of the allocation rule determined based on the second information is higher.

[0485] Steering Functionality;

[0486] Steering Mode;

[0487] Threshold value;

[0488] Transport Mode

[0489] Shunt mode indication.

[0490] In a specific implementation, the first access method or the second access method includes at least one of the following:

[0491] 3GPP access;

[0492] Non-3GPP access.

[0493] The rule determination method provided in the embodiment of the present application can achieve Figure 3 The various processes implemented by the method embodiment and achieving the same technical effect are not described here to avoid repetition.

[0494] In a third aspect, a rule determination method is provided, the method being applied to a third communication device, see Figure 7 FIG. 1 is a flowchart of an implementation method of a rule determination method provided in an embodiment of the present application, and the method includes at least the following steps:

[0495] Step S710: The third communication device receives third information, where the third information is used to determine a first rule, where the first rule is used to determine a flow allocation or distribution method of uplink flow or downlink flow in the first access mode and / or the second access mode;

[0496] The third communication device generates a first rule according to the third information;

[0497] The third communication device sends the first rule to the UE or the user plane function UPF.

[0498] In the embodiment of the present application, the third communication device can generate a first rule based on the third information, for example, an ATSSS rule. Since the third information is generated based on the second information (artificial intelligence analysis result), the first rule at this time is also a rule generated after intelligent analysis or based on artificial intelligence.

[0499] In an embodiment of the present application, the third communication device can also directly request the second communication device to provide the second information, and then the third communication device generates the first rule based on the second information. At this time, the third communication device independently generates intelligent rules based on the artificial intelligence analysis results, such as generating ATSSS rules.

[0500] In an embodiment of the present application, the third communication device may also request the second communication device to provide the second information after receiving the third information. That is to say, after the third communication device receives the third information (such as the PCC rule), it believes that some parameters in the PCC rule can also be subjected to artificial intelligence analysis or optimization. Then, the third communication device will request to obtain the second information from the second communication device, and then, the third communication device will generate the first rule based on the second information.

[0501] It can be seen from the above steps that in an embodiment of the present application, the first communication device sends a first request to the second communication device to request the second information from the second communication device, and then determines the third information based on the second information provided by the second communication device, and the third information is used to determine the first rule, and the first rule is used to determine the traffic allocation or distribution method of the uplink traffic or downlink traffic under the first access method and / or the second access method. In this way, the first communication device determines the allocation rule using the second information provided by the second communication device, that is, the first communication device determines the allocation rule with reference to the second information provided by the second communication device. Because the second information is the result obtained through AI artificial intelligence analysis, the accuracy of the allocation rule determined based on the second information is higher.

[0502] In a specific implementation, the first rule includes at least one of the following:

[0503] Steering Functionality;

[0504] Steering Mode;

[0505] Threshold value;

[0506] Transport Mode
