[0111] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0112] Figure 1 A diagram of a service-based network architecture provided in an embodiment of the present application, such as Figure 1 As shown, Figure 1 The network architecture shown may include three parts, namely, the terminal equipment part, the data network (DN) and the operator network part. The functions of some network elements are briefly introduced below.

[0113] The operator network may include one or more of the following network elements: network exposure function (NEF) network element, network repository function (NRF) network element, policy control function (PCF) network element, unified data management (UDM) network element, network data analytics function (NWDAF) network element, application function (AF) network element, access and mobility management function (AMF) network element, session management function (SMF) network element, radio access network (RAN), unified data repository (UDR) (not shown in the figure) and user plane function (UPF) network element, etc. In the above operator network, the part other than the radio access network part can be called the core network part.

[0114] Terminal device, also known as user equipment (UE), is a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal device can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. For ease of explanation, this application will use UE instead of terminal device for explanation.

[0115] The above-mentioned terminal device can establish a connection with the operator network through the interface provided by the operator network (such as N1, etc.), and use the data and / or voice services provided by the operator network. The terminal device can also access the DN through the operator network, use the operator services deployed on the DN, and / or services provided by a third party. Among them, the above-mentioned third party may be a service provider outside the operator network and the terminal device, and can provide other data and / or voice services to the terminal device. Among them, the specific form of the above-mentioned third party can be determined according to the actual application scenario, and is not limited here. RAN is a subnetwork of the operator network and is an implementation system between the service node and the terminal device in the operator network. For the terminal device to access the operator network, it first passes through the RAN, and then can be connected to the service node of the operator network through the RAN. The RAN device in this application is a device that provides wireless communication functions for terminal devices, and the RAN device is also called an access network device. The RAN equipment in this application includes but is not limited to: the next generation base station (g nodeB, gNB) in 5G, evolved node B (evolved node B, eNB), radio network controller (radio network controller, RNC), node B (node ​​B, NB), base station controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved nodeB, or home node B, HNB), baseband unit (baseBand unit, BBU), transmission point (transmitting and receiving point, TRP), transmission point (transmitting point, TP), mobile switching center, etc.

[0116] AMF network element, mobility management function, is responsible for user mobility management, including mobile state management, allocation of user temporary identity, authentication and authorization of users.

[0117] SMF network element, session management function, responsible for UPF selection, UPF reselection, IP address allocation, responsible for bearer establishment, modification and release, QoS control.

[0118] UPF network element supports all or part of the following functions: interconnecting protocol data unit (PDU) sessions with data networks; packet routing and forwarding (for example, supporting forwarding of traffic to the data network after Uplink classifier, supporting Branching point to support multi-homed PDU sessions); data packet detection.

[0119] DN is a network outside the operator network. The operator network can access multiple DNs. Multiple services can be deployed on DN, which can provide data and / or voice services to terminal devices. For example, DN is the private network of a smart factory. The sensors installed in the workshop of the smart factory can be terminal devices. The control server of the sensors is deployed in DN, and the control server can provide services for the sensors. The sensors can communicate with the control server, obtain instructions from the control server, and transmit the collected sensor data to the control server according to the instructions. For another example, DN is the internal office network of a company. The mobile phones or computers of the company's employees can be terminal devices. The employees' mobile phones or computers can access information and data resources on the company's internal office network.

[0120] The UDM network element is responsible for managing contract data and notifying the corresponding network element when the contract data is modified.

[0121] UDR is used to store and retrieve contract data, policy data, and public architecture data, etc.; it is used by UDM, PCF, and NEF to obtain relevant data. UDR should have different data access authentication mechanisms for different types of data, such as contract data and policy data, to ensure the security of data access; UDR should be able to return a failure response with an appropriate reason value for illegal service operations or data access requests.

[0122] NEF network element is mainly used to support the opening of capabilities and events.

[0123] AF network element provides some application layer services to UE. When providing services to UE, AF has requirements for QoS policy and charging policy (Charging), and needs to notify the network. At the same time, AF also needs application-related information fed back by the core network.

[0124] The PCF network element includes policy control decision-making and flow-based charging control functions, including user subscription data management functions, policy control functions, charging policy control functions, QoS control, etc.

[0125] NRF network elements can be used to provide network element discovery functions and provide network element information corresponding to the network element type based on requests from other network elements. NRF also provides network element management services, such as network element registration, update, deregistration, and network element status subscription and push.

[0126] NWDAF network element can be used to provide data collection, training, analysis, and distribution of analysis results to other functional network elements to help other functional network elements optimize corresponding policy controls. For example, NWDAF provides mobility analysis information of terminal devices to AMF to assist AMF in formulating mobility-related policies, or NWDAF provides session analysis information of terminal devices to SMF to assist SMF in formulating session management-related policies.

[0127] Figure 1 Among them, Nnef, Nnrf, Npcf, Nudm, Nnwdaf, Naf, Namf, Nsmf, N1, N2, N3, N4, and N6 are interface serial numbers. The meanings of these interface serial numbers can be found in the meanings defined in the 3rd Generation Partnership Project (3GPP) standard protocol, and are not limited here.

[0128] Figure 2 A schematic diagram of a reference point-based network architecture provided in an embodiment of the present application, such as Figure 2 The network architecture is also based on point-to-point interfaces. The functions of the network elements can be found in Figure 1 The introduction of the functions of the corresponding network elements will not be repeated here. Figure 2 and Figure 1 The main differences are: Figure 2 The interfaces between the various network elements in the network are point-to-point interfaces, not service-oriented interfaces. Figure 2 It also includes other network elements, such as NEF network elements, NRF network elements, UDR, NWDAF network elements, etc. Figure 2 Not shown.

[0129] exist Figure 2 In the architecture shown, the interface between the UE and the AMF network element is called the N1 interface, the interface between the AMF network element and the RAN device is called the N2 interface, the interface between the RAN device and the UPF network element can be called the N3 interface, the interface between the SMF network element and the UPF network element is called the N4 interface, the interface between the PCF network element and the AF network element is called the N5 interface, the interface between the UPF network element and the DN is called the N6 interface, the interface between the SMF network element and the PCF network element is called the N7 interface, the interface between the AMF network element and the UDM network element is called the N8 interface, the interface between different UPF network elements is called the N9 interface, the interface between the UDM network element and the SMF network element is called the N10 interface, the interface between the AMF network element and the SMF network element is called the N11 interface, the interface between different AMF network elements is called the N14 interface, and the interface between the AMF network element and the PCF network element is called the N15 interface.

[0130] It is understandable that the above network element or function can be a network element in a hardware device, a software function running on dedicated hardware, or a virtualized function instantiated on a platform (e.g., a cloud platform). Optionally, the above network element or function can be implemented by one device, or by multiple devices, or a functional module in one device, which is not specifically limited in the embodiments of the present application.

[0131] The mobility management network element, session management network element, policy control network element, application function network element, access network equipment, network open function network element, and user plane network element in this application can be Figure 1 or Figure 2 The AMF, SMF, PCF, AF, RAN, NEF, and UPF in the network may also be network elements with the functions of the above-mentioned AMF, SMF, PCF, AF, RAN, NEF, and UPF in future communications such as the sixth generation (6G) network, and this application is not limited to this. For the convenience of explanation, this application takes the mobility management network element, session management network element, policy control network element, application function network element, access network equipment, network open function network element, and user plane network element as the above-mentioned AMF, SMF, PCF, AF, RAN, NEF, and UPF as examples. In addition, this application takes the terminal device as UE as an example.

[0132] The data analysis network element in this application can be a network element with data collection, training, analysis, and reasoning functions. It can collect relevant data from network network elements, third-party service servers, terminal devices, or network management systems, perform analysis and training based on relevant data, and provide data analysis information to network network elements, third-party service servers, terminal devices, or network management systems. For example, the data analysis network element can be NWDAF, management data analysis service (MDAS). The data analysis network element can be a single network element, a combination of multiple network elements, or co-located with other network elements.

[0133] The network in the present invention can be any type of network including PLMN, private network, network slice, slice instance, and slice sub-instance. For the sake of simplicity of description, the present invention does not explicitly reflect that the training data collected by the data analysis network element and the analysis information generated include network identification information. For example, for network slicing, the training data actually collected or the analysis information generated by the data analysis network element may include slice identification information, such as network slice selection assistance information (NSSAI), single network slice selection assistance information (S-NSSAI), network slice instance (NSI) ID, network slice subnet instance (NSSI) ID, etc.

[0134] The analysis information involved in the present invention may be statistical information or prediction information. For example, the service experience analysis information may be service experience statistical information or service experience prediction information; the service behavior analysis information may be service behavior statistical information or service behavior prediction information.

[0135] Figure 3 This is a schematic diagram of the dual-connection 5G network architecture provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the interoperability architecture of a single-connection 5G network and a 4G network provided in an embodiment of the present application.

[0136] like Figure 3 In the network architecture shown in FIG, terminal devices can access the 5G network via NR or LTE, but the corresponding core is the same core network 5GC. Figure 4 In the network architecture shown, the terminal device can access the 4G network via LTE and the 5G network via NR, and the corresponding core networks are independent core networks EPC and 5GC.

[0137] for Figure 3 Architecture, 5G network has a network deployment scenario where two radio access types (radio access type, RAT) access networks, enhanced long term evolution (eLTE) and new radio (NR), coexist, and each RAT may have multiple access frequencies (such as 2.6GHZ, 3.5GHZ, 700MHZ, 900MHZ, etc.).

[0138] for Figure 4Architecture: Before the 4G network is completely withdrawn, terminal devices will have interoperability scenarios in 5G and 4G networks. The RATs of 5G and 4G networks may be different, and each RAT may have multiple access frequencies.

[0139] For the above two scenarios, there may be the following problems: 1) Different services require different RATs or access frequencies to carry in order to achieve better service effects. For example, voice services are more stable when running on eLTE / LTE networks, while cloud AR / VR is more sensitive to data rate and latency, so it needs to run on NR. 2) RAT or access frequency allocation can be made for users and services of different values. For example, NR has high cost and high quality, so it gives priority to serving high-value services and users. 3) For the purpose of network load balancing and network energy saving, the RAT or access frequency allocation scheme needs to be dynamically and adaptively changed according to time and location. For example, when the NR load is low, it can serve some low-value services. On the contrary, when low-value services are transferred to eLTE / LTE, or when the RAT or access frequency needs to be closed due to low cell utilization during a period of time, existing users need to transfer to other RATs or access frequencies.

[0140] The present application provides a method for determining a policy, in which a data analysis network element generates analysis information based on the acquired network data and service data, and provides the analysis information to a network network element, and the network network element allocates a dynamically variable RAT or access frequency to a terminal device according to the analysis information to meet the service experience requirements of the terminal device. In the embodiment of the present application, NWDAF can be replaced by any other network element or functional module with data analysis capabilities, and the network network element can be a core network network element, an access network network element, a terminal device, an application server, a network management network element, etc., which is not limited here.

[0141] Figure 5 It is a flowchart of a method for determining a strategy provided in an embodiment of the present application.

[0142] S201, a first network element obtains first analysis information from a data analysis network element, where the first analysis information includes at least one of the following information: relevant information about RAT or relevant information about access frequency, and service experience analysis information corresponding to the RAT or access frequency.

[0143] It should be understood that the first network element can be a network element with decision-making functions, which can provide various relevant strategies for network devices or terminal devices. For example, it can be PCF, AMF, RAN, etc. The first network element in this embodiment specifically involves the decision of wireless access information strategy. The data analysis network element can be a network element with data collection, training, analysis, and reasoning functions. It can collect relevant data from network network elements, third-party service servers, terminal devices, or network management systems, perform analysis and training based on relevant data, and provide data analysis information to network network elements, third-party service servers, terminal devices, or network management systems. For example, the data analysis network element can be NWDAF, MDAS, etc. The data analysis network element can be a single network element, a combination of multiple network elements, or a combination of the first network element or other network elements.

[0144] Optionally, the relevant information of RAT or the relevant information of access frequency includes at least one of the following information: an identifier of the terminal device, a service type, a recommended RAT or a recommended access frequency, time information, and area information. The relevant information of RAT or the relevant information of access frequency may be a recommended RAT or a recommended access frequency for at least one terminal device. For example, for a specific terminal device, it may be recommended to access eLTE or 700MHZ; the relevant information of RAT or the relevant information of access frequency may also be a recommended RAT or a recommended access frequency for at least one service type. For example, for voice services, it may be recommended to access eLTE or 700MHZ; the relevant information of RAT or the relevant information of access frequency may also be a recommended RAT or access frequency for at least one service type of at least one terminal device. For example, for an ongoing AR / VR service of a terminal device, it may be recommended to access NR or 3.5GHz, while for an ongoing voice service of a terminal device, it may be recommended to access eLTE or 700MHZ. And the relevant information of the RAT or the relevant information of the access frequency may change dynamically with time, location, or other factors. For example, different RATs or frequencies are recommended when the terminal device uses voice services on a subway or in a square, and can be configured based on actual needs.

[0145] It should be understood that the service type or service type of the terminal device involved in the present application may be only one service type or multiple service types.

[0146] Optionally, the service experience analysis information corresponding to the RAT or access frequency includes at least one of the following information: an identifier of the terminal device, a service type, a RAT or access frequency, a service experience of the service type, time information, and area information. The service experience analysis information corresponding to the RAT or access frequency can be used to indicate the service experience corresponding to at least one service type under the RAT or access frequency, for example, the mean opinion score (MOS) of the voice service when running under NR / 3.5GHz is 3 points, while the MOS of the voice service when running under LTE / 700Hz is 4.5 points. The service experience analysis information corresponding to the RAT or access frequency can also be used to indicate the service experience corresponding to at least one service type of at least one terminal device under the RAT or access frequency, for example, the mean opinion score (MOS) of the voice service of a particular terminal device when running under NR / 3.5GHz is 3.5 points, while the MOS of the voice service of the terminal device when running under LTE / 700Hz is 4 points.

[0147] In the present invention, one form of expression of service experience is MOS, which can also be other forms of expression, such as delay, fluency, throughput, packet loss rate, jitter, flow, etc.; service experience can also be a combination of multiple experience parameters, such as delay and fluency combined experience, which is not limited here. Optionally, the first network element can be a core network element, a network management network element, an application server, etc., wherein the core network element includes a control plane network element or a user plane network element.

[0148] Optionally, the first network element may also be an access network element, such as RAN, and the access network element may directly obtain the first analysis information provided by the data analysis network element, and perform relevant RAT or frequency selection operations for the terminal device according to the first analysis information. For example, after the access network element selects a suitable target RAT or target access frequency for the terminal device according to the first analysis information, if the terminal is in a connected state, the access network element may switch the terminal device to a target cell corresponding to a target RAT or target access frequency through a switching process; or, the access network element may send the relevant target RAT or target access frequency to the terminal device through a redirection process, so that the terminal device can select to access the target RAT or target access frequency after entering the idle state. For another example, after the access network element selects a suitable target RAT or target access frequency for the terminal device according to the first analysis information, if the terminal is currently in an idle state, the access network element may wait for the terminal device to enter a connected state, or after the access network pages the terminal device to a connected state, and then use a switching or redirection method in the connected state to enable the terminal device to access the target RAT or target access frequency.

[0149] Optionally, the first network element may also be a terminal device, and the terminal device directly obtains the first analysis information provided by the data analysis network element, and accesses the relevant RAT or relevant frequency with reference to the first analysis information. For example, the terminal device selects a suitable target RAT or target access frequency according to the first analysis information, and the terminal device can access the cell corresponding to the target RAT or target access frequency by performing network reselection or cell reselection.

[0150] S202, the first network element determines an access information selection strategy for the terminal device according to the first analysis information, where the access information selection strategy includes a target RAT or a target access frequency corresponding to the terminal device.

[0151] Optionally, the first network element determines a target RAT or a target access frequency corresponding to the terminal device according to the first analysis information, so that the service type of the terminal device can meet a preset condition under the target RAT or the target access frequency. The service type of the terminal device may include one or more service types of the terminal device.

[0152] In a possible implementation, when the first analysis information is RAT-related information or access frequency-related information, and the RAT or access frequency information includes a RAT or a recommended access frequency recommended for a terminal device, the first network element determines the access information selection strategy of the terminal device based on the first analysis information, and the method includes: the first network element determines the RAT or the recommended access frequency recommended for the terminal device as the target RAT or target access frequency corresponding to the terminal device. As shown in Table 1 below, the first analysis information includes the RAT or the recommended frequency recommended for terminal device A, terminal device B, and terminal device C, then the first network element determines the RAT or the recommended frequency eLTE / 900MHZ recommended for terminal device A as the target RAT or target access frequency of terminal device A, wherein eLTE / 900MHZ can make the service experience of terminal device A meet preset conditions (such as optimal).

[0154]

[0155] In a possible implementation, when the first analysis information is RAT-related information or access frequency-related information, and the RAT or access frequency information includes a recommended RAT or a recommended access frequency for at least one service type, the first network element determines the access information selection strategy of the terminal device based on the first analysis information, and the method includes: the first network element determines the service type that the terminal device has initiated or is about to initiate, and the first network element determines the recommended RAT or recommended access frequency corresponding to the service type that the terminal device has initiated or is about to initiate as the target RAT or target access frequency corresponding to the terminal device. As shown in Table 2 below, the first analysis information includes the recommended RAT or recommended frequency for service A, service B, and service C. If the first network element determines that the terminal device has initiated or is about to initiate service type A, the first network element determines the recommended RAT or recommended frequency eLTE / 900MHZ for service A as the target RAT or target access frequency of the terminal device, wherein eLTE / 900MHZ can make the service A experience of terminal device A meet preset conditions (such as optimal).

[0158] In one possible implementation, when the first analysis information is RAT-related information or access frequency-related information, and the RAT or access frequency information includes a recommended RAT or a recommended access frequency for at least one service type of the terminal device, the first network element determines the access information selection strategy of the terminal device based on the first analysis information, and the method includes: the first network element determines the service type that the terminal device has initiated or is about to initiate, and the first network element determines the recommended RAT or recommended access frequency corresponding to the service type that the terminal device has initiated or is about to initiate as the target RAT or target access frequency corresponding to the terminal device. As shown in Table 3 below, for example, the first analysis information includes the recommended RAT or recommended frequency for service A of terminal device A, service B of terminal device A, service A of terminal device B, and service C of terminal device B. If the first network element determines that terminal device A has initiated or is about to initiate service A, the first network element will determine the RAT or recommended frequency NR / 2.6GHZ recommended for service A of terminal device A as the target RAT or target access frequency of terminal device A, wherein NR / 2.6GHZ can make the service A experience of terminal device A meet preset conditions (such as optimal).

[0159] Table 3

[0160]

[0161] In one possible implementation, when the first analysis information is the service experience analysis information corresponding to the RAT or access frequency, and the service experience analysis information corresponding to the RAT or access frequency includes the service experience corresponding to at least one service type under the RAT or access frequency, the first network element determines the access information selection strategy of the terminal device based on the first analysis information. The method includes: the first network element determines the service type that has been initiated or is to be initiated by the terminal device, and for the service type that has been initiated or is to be initiated by the terminal device, the first network element determines the target RAT or target access frequency from the service experience analysis information corresponding to the RAT or access frequency, so that the service experience corresponding to the service type that has been initiated or is to be initiated by the terminal device under the target RAT or target access frequency can meet the preset conditions. As shown in Table 4 below, for example, the first analysis information includes the service experience corresponding to service A, service B, and service C under the RAT or access frequency. If the first network element determines that the terminal device has initiated or is about to initiate service A, the first network element determines eLTE / 900MHZ as the target RAT or target access frequency for the terminal device based on the service experience corresponding to service A under the RAT or access frequency, wherein eLTE / 900MHZ can make the service A experience meet preset conditions (such as optimal).

As shown in Table 5 below, for example, the first analysis information includes service A for terminal device A, service B for terminal device A, and service C for terminal device A corresponding to the service experience under RAT or access frequency. If the first network element determines that terminal device A has initiated or is about to initiate service A, the first network element determines the target RAT or target access frequency of NR / 2.6GHZ terminal device A based on the service experience corresponding to service A for terminal device A under RAT or access frequency, wherein NR / 2.6GHZ can make the service A experience of terminal device A meet preset conditions (such as optimal).

[0165] Table 5

[0166]

[0167] The preset condition of the service experience in the present invention may be configured in the first network element or from other network elements, such as from NWDAF. The preset condition may be that the service experience is optimal or that the service experience is greater than a certain set level or value, etc., and the form is not limited.

[0169] Optionally, the first network element may also obtain the business behavior analysis information of the terminal device sent by the data analysis network element, and the first network element predicts the type of service that the terminal device will trigger based on the business behavior analysis information of the terminal device. Among them, the first network element may obtain the business behavior analysis information of the terminal device from the data analysis network element alone, or may simultaneously obtain the first analysis information and the business behavior analysis information of the terminal device from the data analysis network element. The business behavior analysis information of the terminal device refers to data analysis information that can reflect the situation or regularity of the terminal device's use of the service. The business behavior analysis information of the terminal device includes at least one of the following information: the terminal device's identification, time information, area information, service type, priority information of the service type, probability of occurrence of the service type, and duration of the service type.

[0170] Optionally, the business behavior analysis information of the terminal device includes business behavior statistical information of the terminal device, or business behavior prediction information of the terminal device, that is, the business behavior analysis information can be obtained based on historical business behavior data statistics of the terminal device, or can be obtained through prediction, such as based on the business behavior data of another terminal device with the same user profile as the terminal device.

[0171] Optionally, the first network element sends a first request message to the data analysis network element, the first request message includes a service type, wherein the service type may be one or more service types, and the first request message is used to request first analysis information corresponding to the service type. The first network element receives a first response message sent by the data analysis network element, and the first response message includes first analysis information corresponding to the service type.

[0172] Optionally, the first network element sends a first request message to the data analysis network element, and the first request message includes an identifier of the terminal device. The identifier of the terminal device may be an identifier of a terminal device for which an access information selection strategy is currently to be determined, or may be identifiers of multiple terminal devices including the identifier of the current terminal device. The first request message is used to request first analysis information corresponding to the terminal device. The first network element receives a first response message sent by the data analysis network element, and the first response message includes the first analysis information corresponding to the terminal device.

[0173] Optionally, the first network element sends a first request message to the data analysis network element, the first request message including the identifier of the terminal device and the service type, the identifier of the terminal device may be the identifier of the terminal device for which the access information selection policy is currently to be determined, or the identifiers of multiple terminal devices including the identifier of the current terminal device, and the service type may be one or more service types. The first request message is used to request first analysis information corresponding to the service type of the terminal device, and the first network element receives a first response message sent by the data analysis network element, the first response message including the first analysis information corresponding to the service type of the terminal device.

[0174] In the present application, the terminal device identifier may include one or more of the following identifiers corresponding to the terminal device: IMSI, IMEI, SUPI, GPSI, association identifier, IP quintuple, etc. The terminal device identifier may also be an identifier of a terminal device group, in which case the first request is used to request the first analysis information corresponding to the terminal device group.

[0175] Optionally, the first network element may also obtain an applicable condition of the first analysis information, the applicable condition including at least one of the following information: service type, user type, user identification, time information, and area information. The applicable condition of the first analysis information is used to indicate under which conditions the first analysis information is available.

[0176] The user type may indicate user level or user priority information, such as gold, silver, and bronze users. The user type may also indicate user classification information, such as office worker users, student users, and the like.

[0177] Optionally, the user identifier may be an identifier of a single user or an identifier of a user group. In the present application, the meanings of user and terminal device may be the same, and the meaning of user identifier and terminal identifier are the same.

[0178] Optionally, the first network element determines the access information selection strategy based on the first analysis information and the first information, wherein the first information includes at least one of the following information: priority information of the service type, charging policy information of the service type, user type of the terminal device, load / flow information of the RAT or access frequency, mobile mode analysis information of the terminal device, and communication mode analysis information of the terminal device. The load / flow information of the RAT or access frequency includes load / flow information of different RATs or access frequencies in a certain area (such as a cell, TA); the mobile mode analysis information of the terminal device includes analysis information on the mobility management-related behaviors of the terminal device, such as the mobile trajectory information of the terminal device; the communication mode analysis information of the terminal device includes analysis information on the session management-related behaviors of the terminal device, such as the time point and duration of the session initiated by the terminal device. The first information can come from the first network element itself or from other network elements (such as SMF, AF, NWDAF, etc.).

[0179] For example, the first network element determines, based on the service behavior analysis results of the terminal device, that the probability of two types of services occurring in a certain scenario is equal for the terminal device, but the priority of service A is higher than that of service B. The first network element can select the RAT or frequency that can provide the best experience for service A as the target RAT or target access frequency of the UE based on the service experience analysis information of service A. For another example, the first network element determines, based on the above two data analysis results, that the wireless access information of the terminal device is RAT A, but the network load of the cell corresponding to RATA (such as NR) is already high, and the priority of the terminal device is relatively low. The first network element can decide to select RAT B (such as EUTRAN) as the wireless access information for the terminal device.

[0180] Optionally, when the first network element is a core network element or a network management element or a service server, the first network element sends a first indication message to the access network element or the terminal device, and the first indication message may include an access information selection policy for the terminal device.

The applicable condition of the access information selection policy is used to indicate under which conditions the access information selection policy is applicable.

[0182] Figure 6 It is an interactive schematic diagram of a strategy determination method provided in an embodiment of the present application.

[0183] S301, a first network element sends a first request message to a data analysis network element. The first request message is used to obtain first analysis information from the data analysis network element. The content of the first analysis information is similar to Figure 5 The content of the first analysis information in the embodiment will not be repeated here.

[0184] The method in which the first network element sends the first request message to the data analysis network element is similar to Figure 5 The method of the first network element sending the first request message to the data analysis network element in the embodiment will not be repeated here.

[0185] In a specific implementation, the first request message may carry two analysis type identifiers (analytic IDs), the first analysis type identifier is used to indicate that the request is for business behavior analysis information of the terminal device, and the second analysis type identifier is used to indicate that the request is for the first analysis information.

[0186] Optionally, the first request message includes a terminal device identifier, and the first request message is used to request the service behavior analysis information corresponding to the terminal device identifier. Figure 5 The identification of the terminal device in the embodiment will not be repeated here.

[0187] Optionally, the first request message includes a service type, which may be one or more service types, and the first request message is used to request service behavior analysis information of the terminal device corresponding to the service type. For example, if the first request message includes a voice service type, the first request message is used to request service behavior analysis information of the terminal device regarding the voice service.

[0188] Optionally, when the first request information carries the first analysis type identifier, the first network element may also generate business behavior analysis information of the terminal device, and the business behavior analysis information may be sent to the first network element together with the first analysis information, or sent separately.

[0189] Optionally, the first network element may also carry filtering information in the first request message, which is used to identify the request corresponding to the filtering information, or the analysis information that satisfies the filtering conditions, such as time filtering conditions or location filtering conditions. The analysis information may be the first analysis information or the terminal device business behavior analysis information. In addition, the filtering information may be different for different analysis information, for example, the filtering information of the first analysis information is filtering information 1, and the filtering information of the business behavior analysis information is filtering information 2.

[0190] Optionally, the first network element may also carry a reporting condition in the first request message, which is used to instruct the data analysis network element to feedback the analysis information according to the reporting condition. For example, the reporting condition may be the time set by the timer, which is used to instruct the data analysis network element to feedback the first analysis information within a period of time after receiving the first request message, or to feedback the first analysis information after the first analysis information meets the preset condition, or to periodically report the first analysis information, etc. In addition, the reporting conditions may be different for different analysis information, for example, the filtering information of the first analysis information is reporting condition 1, and the filtering information of the business behavior analysis information is reporting condition 2.

[0191] S302: The data analysis network element obtains relevant training data.

[0192] Optionally, the data analysis network element can obtain data from application function network elements (application function, AF), network function network elements (network function, NF), OAM, terminal equipment, etc., where NF may include session management function network elements (session management function, SMF) or access and mobility management function network elements (access and mobility management function, AMF), UPF, PCF, NRF, etc., and network management network elements include operation, administration and maintenance network elements (operation, administration and maintenance, OAM) and other network elements.

[0193] Optionally, the data obtained by the data analysis network element can be divided into network data or service data. Network data refers to data obtained from the communication network, which may include at least one of the following information: terminal device identification, time information, area information, RAT or access frequency; service data refers to data obtained from the service server, which may include at least one of the following information: terminal device identification, service type, and service experience.

[0194] Among them, the identifier of the terminal device may include the IMSI, IMEI, SUPI, GPSI, association identifier, IP quintuple, etc. corresponding to the terminal device.

[0195] It should be understood that the identification of the terminal device obtained by the data analysis network element may be the identification of the terminal device to be analyzed, or may be identifications of multiple terminal devices including the terminal device to be analyzed, or may be one or more of the identifications of the terminal device.

[0196] The identifier of the terminal device may be a specific single terminal device, or may be multiple terminal devices or a terminal device group.

[0197] In a possible implementation, in order to obtain business behavior analysis data of a terminal device, the training data obtained by the data analysis network element may include data as shown in Table 6.

[0198] Table 6

[0199]

[0200] Optionally, the identifier of the terminal device in Table 6 is the identifier of the terminal device to be analyzed, which is used to identify a specific single terminal device or a single terminal device group. That is, the data analysis network element only obtains the information in the above table for a specific terminal device to analyze the business behavior of the terminal device. It should be understood that Table 6 is only an exemplary statement, and this application does not limit the type of data obtained.

[0201] Optionally, the training data used for the data analysis network element to analyze the first analysis information may include data as shown in Table 7.

[0202] Table 7

[0203]

[0204]

[0205] Optionally, the identifier of the terminal device in Table 7 is the identifier of the terminal device to be analyzed. In one possible implementation, the terminal device identifier is used to generally refer to a single terminal device or a single terminal device, that is, the data analysis network element obtains data about a large number of terminal devices in Table 7, and generates first analysis information of non-specific terminal devices based on this analysis; in another possible implementation, the terminal device identifier is used to specifically refer to a single terminal device or a single terminal device, that is, the data analysis network element only obtains the information in the above Table 7 for a specific terminal device, which is used to analyze the first analysis information of the terminal device. It should be understood that Table 7 is only an exemplary statement. The present application does not limit the type of data obtained, and does not limit each data type listed in Table 7 to be mandatory. For example, NWDAF does not need to collect the RAT or frequency of the terminal device from network elements such as AMF, but obtains the cell identifier of the terminal device from AMF. If NWDAF itself is configured with the RAT or frequency corresponding to the cell identifier, NWDAF can eventually obtain service experience analysis information based on RAT or frequency.

[0206] The following step 303 is explained by assuming that the first analysis information is service experience analysis information corresponding to the RAT or access frequency.

[0207] S303: Based on the acquired training data, the data analysis network element analyzes and acquires service experience analysis information corresponding to the RAT or access frequency.

[0208] The service experience analysis information corresponding to RAT or access frequency refers to the analysis information reflecting the association between the service experience of the service type of the terminal device and the wireless access information, that is, the analysis information of the association between the service experience and the RAT or access frequency, as shown in Table 8.

[0209] Table 8

[0210]

[0211] It should be understood that how the data analysis network element obtains the service experience analysis information corresponding to the output RAT or access frequency based on the input training data is not limited here, and can be based on big data statistics or prediction methods.

[0212] S304: Based on the acquired data, the data analysis network element analyzes and acquires the service behavior analysis information of the terminal device.

[0213] The service behavior analysis information of the terminal device refers to data analysis information that can reflect the situation or regularity of the terminal device's use of services.

[0214] Optionally, the service behavior analysis information includes at least one of the following information: identification of the terminal device, time information, area information, service type, priority information of the service type, probability of occurrence of the service type, and duration of the service type.

[0215] In a possible implementation, the data analysis network element may analyze and obtain the business behavior analysis information of the terminal device as shown in Table 9.

[0216] Table 9

[0217]

[0218]

[0219] It should be understood that the analysis information content in the above Table 9 is only for example, and not every item of information is necessarily required.

[0220] Optionally, the service behavior analysis information of the terminal device includes service behavior statistics of the terminal device or service behavior prediction information of the terminal device. In other words, the content (such as the probability of service occurrence) contained in the service behavior analysis information of the terminal device can be used as statistical information or as prediction information.

[0221] How the data analysis network element obtains the output terminal device's business behavior analysis information based on the input data is not limited here, and can be based on big data statistics or prediction methods.

[0222] For example, when the service behavior analysis information of the terminal device is the service behavior prediction information of the terminal device, the data analysis network element needs to determine the service behavior prediction information of a single terminal device.

[0223] Optionally, the data analysis network element may analyze the business behavior analysis information of the terminal device based on a prediction method. For example, the data analysis network element determines the user portrait classification information to which the terminal device belongs. The data analysis network element predicts the business behavior of the terminal device based on the user portrait classification information to which the terminal device belongs and the historical business behavior information of terminal devices of the same portrait type to determine the business behavior analysis information of the terminal device.

[0224] Optionally, the data analysis network element collects network behavior data, business behavior data, and business attribute data at the terminal device level, and the data analysis network element determines a user portrait classification model based on the network behavior data, business behavior data, and business attribute data at the terminal device level. The data analysis network element determines user portrait classification information of the terminal device to be analyzed based on the user portrait classification model and the network behavior data, business behavior data, and business attribute data of the terminal device to be analyzed.

[0225] It should be understood that the data analysis network element can determine the business behavior of the terminal device to be analyzed based on another terminal device with the same user portrait classification as the terminal device to be analyzed, that is, if the other terminal device has the same or similar business behavior as the terminal device to be analyzed in history, for example, the same business behavior was performed at certain time points or places in the past, then the business behavior of the terminal device to be analyzed can be predicted based on the business behavior of the other terminal device at the current time or place.

[0226] It should be noted that steps 302 to 304 are not dependent on step 301, and they have no temporal relationship with step 301. In other words, the data analysis network element can obtain relevant training data and generate relevant analysis information in advance, and does not have to wait until the first request message is received before performing relevant operations.

[0227] S305, the data analysis network element sends a first response message to the first network element, where the first response message includes first analysis information.

[0228] The first analysis information is the analysis message corresponding to the first request message in S301.

[0229] Optionally, the first response message also includes business behavior analysis information of the terminal device.

[0230] It should be understood that the business behavior analysis information of the terminal device may not be included in the first response message, but may be sent separately.

[0231] Optionally, the service experience analysis information and the service behavior analysis information may be dynamically changed according to the scenario, that is, they may be sent all at once or in batches.

[0232] Optionally, the data analysis network element may send the applicable conditions of the analysis information to the first network element separately, that is, not including it in the service experience analysis information and the service behavior analysis information; it may be included in the first response message or sent separately and not included in the first response message.

[0233] S306: The first network element obtains first analysis information and determines an access information selection strategy for the terminal device.

[0234] Among them, the access information selection strategy of the terminal device is used to indicate the target RAT or target access frequency that the terminal device should access in a certain scenario (time, place, etc.).

[0235] In one possible implementation, the access information selection strategy determined by the first network element may be expressed as the first network element generating a dynamically variable frequency selection priority (RAT / frequency selection priority, RFSP) / radio or frequency selection priority (subscriber profile ID for RAT / frequency selectionpriority, SPID) for the terminal device, where the RFSP / SPID is used to indicate the priority of RAT or access frequency selection. For example, in a certain scenario (a certain time and place), the RFSP / SPID indicates that NR has the highest selection priority, indicating that the terminal device should select NR for residency at this time. In another scenario, the RFSP / SPID indicates that the evolved access network (EUTRAN) has the highest selection priority, and the terminal device should select EUTRAN for residency at this time.

[0236] It should be understood that in addition to the RFSP / SPID method, the access information selection strategy can also have other forms of expression, as long as it can assist the access network element to select a target RAT or a target access frequency for the terminal device or the terminal device itself.

[0237] Optionally, the first network element may determine the access information selection strategy of the terminal device in two steps:

[0238] Step 1: The first network element determines the type of service that the terminal device will use in a certain scenario (time, location, terminal device) based on the service behavior analysis information of the terminal device.

[0239] For example, the selected service type is generally the service type with the highest probability of being used by the terminal device in the current scenario, or the selected service type may be the service type used by the terminal device for the longest time in the current scenario, or the selected service type may be the service type with the highest priority for the terminal device in the current scenario.

[0240] Step 2: Based on the service type obtained in step 1, the first network element determines the target RAT or target access frequency according to the first analysis information, wherein the target RAT or target access frequency can make the service experience of the terminal device meet the preset conditions. For example, eLTE / 700MHZ can make the MOS of the voice service of the terminal device exceed 3 points, then eLTE / 700MHZ will be used as the target RAT or target access frequency corresponding to the terminal device when initiating the voice service. For another example, NWDAF recommends that the voice service of the terminal device access eLTE / 700MHZ, then eLTE / 700MHZ will be used as the target RAT or target access frequency corresponding to the terminal device when initiating the voice service.

[0241] Optionally, in addition to analyzing the information based on the above two types of data, the first network element may also consider the first information to determine the access information selection strategy of the terminal device. The first information may include but is not limited to at least one of the following information:

[0242] Service priority information, such as high priority, low priority, priority value, etc.;

[0243] Service billing policy information, such as high, medium, low rate, rate value, etc.;

[0244] The user type of the terminal device can be level information, such as gold, silver, and bronze users. The user type can also indicate user classification information, such as office worker users, student users, etc.

[0245] Mobile mode analysis information of the terminal device, for example, the mobile track information of the terminal device, whether the terminal device is an immovable physical network terminal device, etc.;

[0246] Communication mode analysis information of terminal devices, such as communication habits of terminal devices;

[0247] Load / traffic information of RAT or access frequency, for example, NR RAT cell has high load and eLTE cell has low load.

[0248] Optionally, the above first information can be configured on the network such as the first network element, or obtained from other network elements such as AMF, billing system, data analysis network element, etc.

[0249] For example, the first network element determines based on the service behavior analysis information of the terminal device that the probability of two types of services occurring in a certain scenario is equal for the terminal device, but service A has a higher priority than service B. The first network element may select the RAT or access frequency that can provide the best experience for service A based on the service experience analysis information of service A.

[0250] For another example, the first network element determines that the wireless access information of the terminal device is RATA based on the above two types of data analysis information, but the network load of RAT A (such as NR) is already high and the user priority of the terminal device is relatively low, then the first network element can determine to select RAT B (such as EUTRAN) as the wireless access information for the terminal device.

[0251] S307, the first network element sends first indication information to the third network element, where the first indication information includes an access information selection strategy for the terminal device determined by the first network element.

[0252] Optionally, when the first network element is a core network element, a network management element, or a service server, the first network element sends a first indication message to the access network element or the terminal device, and the first indication message may include an access information selection policy for the terminal device. The method facilitates the access network element to refer to the access information selection policy to trigger the terminal device to access the corresponding RAT or the corresponding access frequency, wherein the corresponding RAT is the same as or different from the target RAT, and the corresponding access frequency is the same as or different from the target access frequency; or, the method facilitates the terminal device to refer to the access information selection policy to access the corresponding RAT or the corresponding access frequency, wherein the corresponding RAT is the same as or different from the target RAT, and the corresponding access frequency is the same as or different from the target access frequency.

[0253] Optionally, the first network element further sends an applicable condition of the access information selection policy to the access network element or the terminal device, including at least one of the following information: service type, user type, user identifier, time information, and area information. The applicable condition of the access information selection policy is used to indicate under which conditions the access information selection policy is applicable.

[0254] Optionally, the access information selection policy of the terminal device sent by the first network element to the third network element may be an RFSP / SPID policy corresponding to the terminal device.

[0255] Optionally, the access information selection policy of the terminal device changes dynamically with the scenario, that is, the first network element dynamically updates the policy to the third network element, such as updating the policy according to the network area information of the terminal device, or updating the policy according to different time periods, or the access information selection policy can be a dynamic global policy (policy and corresponding applicable conditions (time, place, etc.)), which is sent to the third network element, and then the third network element itself dynamically executes the policy. In a possible implementation, the first network element can send only one RFSP / SPID corresponding to a scenario (time, place, etc.) at a time. If the first network element determines that the scenario of the subsequent terminal device has changed and the corresponding RFSP has changed, the first network element can also update the RFSP to the RAN.

[0256] In another possible implementation, the first network element may also send the RFSP / SPID corresponding to the terminal device in multiple scenarios (time, place, etc.) at one time, and specify the applicable conditions (time, place, RAN load, etc.) for each RFSP / SPID.

[0257] S308, based on the access information selection strategy of the terminal device sent by the first network element, the third network element determines and executes the residence strategy of the terminal device.

[0258] Among them, the third network element can be an access network element or a terminal device.

[0259] Optionally, the resident strategy of the terminal device may specifically be that the terminal device continues to reside in the original RAT or access frequency, or that the terminal device transfers to access other RATs or access frequencies.

[0260] Optionally, when the third network element is an access network element, the third network element executes a strategy for transferring the terminal device to access other RATs or access frequencies specifically as follows: after the access network element selects a suitable target RAT or target access frequency for the terminal device based on the first analysis information, if the terminal is in a connected state, the access network element may switch the terminal device to a target cell corresponding to a target RAT or target access frequency through a switching process; or, the access network element may send the relevant target RAT or target access frequency to the terminal device through a redirection process, so that the terminal device can select to access the target RAT or target access frequency after entering an idle state. For another example, after the access network element selects a suitable target RAT or target access frequency for the terminal device based on the first analysis information, if the terminal is currently in an idle state, the access network element may wait for the terminal device to enter a connected state, or after the access network pages the terminal device to a connected state, and then use a switching or redirection method in the connected state to enable the terminal device to access the target RAT or target access frequency.

[0261] Optionally, when the third network element is the terminal device itself, the strategy of the third network element to transfer access to other RATs or access frequencies is specifically: the terminal device itself performs cell reselection or network reselection to access the cell corresponding to other RATs or access frequencies.

[0262] For example, if the terminal device determines that the current RAT or access frequency has the highest priority based on the RFSP sent by the first network element, the terminal device determines to continue to reside in the current RAT or access frequency. If the terminal device determines that other RATs or access frequencies have the highest priority based on the RFSP sent by the first network element, the terminal device performs cell reselection or network reselection to access cells corresponding to other RATs or access frequencies. Before the terminal device performs cell reselection or network reselection to access cells corresponding to other RATs or access frequencies, if the terminal device is in a connected state at the current RAT or access frequency, the terminal device may wait to enter an idle state before performing cell reselection or network reselection to access cells corresponding to other RATs or access frequencies.

[0263] S309: According to the instruction of the third network element, the terminal device accesses the target RAT or accesses the frequency.

[0264] It should be understood that this step is performed when the third network element is an access network element; if the third network element is a terminal device, the terminal device accesses the target RAT or access frequency, and can initiate services on the target RAT or access frequency.

[0265] After all the above steps, it can be ensured that the terminal device accesses the appropriate RAT or access frequency, and the RAT or access frequency can just ensure that the service experience of the terminal device for the service initiated currently or in the future meets the preset conditions, for example, to optimize the service experience of the terminal device.

[0266] Optionally, the data analysis network element can directly generate relevant information about the RAT or relevant information about the access frequency based on the data, and include it in the corresponding information and send it to the first network element, that is, the data analysis network element directly recommends the RAT or access frequency of the terminal device in a certain scenario to the first network element. In this way, the data analysis network element can directly generate relevant information about the RAT or relevant information about the access frequency in combination with the input data in Table 6 and Table 7 in S302, or it can first generate the service experience analysis information described in S303 and the service behavior analysis information described in S304, and the data analysis network element further generates relevant information about the RAT or relevant information about the access frequency of the terminal device based on the two analysis information in S303 and S304.

[0267] In the technical solution provided in the embodiment of the present application, the data analysis network element can statistically analyze the relationship between service experience information and wireless access information, and the data analysis network element can also statistically analyze user-level service behavior information. Based on the above two, the data analysis network element can assist the first network element in formulating a wireless access information selection strategy for a single terminal device, which is used to select a suitable resident RAT or resident frequency for the terminal device in different scenarios, and the strategy is formulated based on the service type that the terminal device is about to initiate or has initiated, that is, the service type of the terminal device is taken into account. The strategy is dynamically variable, so that the service experience of the terminal device can reach the preset conditions.

[0268] Figure 7 It is an interactive schematic diagram of another strategy determination method provided in an embodiment of the present application.

[0269] like Figure 7 The technical solution shown is applied to the service type being carried out by the terminal device or the service type that has been determined to be initiated by the terminal device, that is, the first network element can already determine the service type initiated by the terminal device.

[0270] Optionally, after the first network element determines the service type of the terminal device (such as receiving a service establishment request message initiated by the AF for the terminal device), the first network element formulates an access selection strategy according to the initiated service type and in combination with the first analysis information, so that the service experience of the service type under the RAT or access frequency indicated in the strategy meets the preset conditions, and the specific steps are as follows:

[0271] S401, a first network element sends a first request message to a data analysis network element.

[0272] The first request message is used to obtain first analysis information from the data analysis network element. The content of the first analysis information is similar to Figure 5 The content of the first analysis information in the embodiment will not be repeated here.

[0273] The method in which the first network element sends the first request message to the data analysis network element is similar to Figure 5 The method of the first network element sending the first request message to the data analysis network element in the embodiment will not be repeated here.

[0274] In a specific implementation manner, the first request message may carry a second analysis type identifier to indicate that the request is for the first analysis information.

[0275] Optionally, the first network element may also carry filtering information in the first request message, which is used to identify the first analysis information corresponding to the request and the filtering information, or satisfying a filtering condition, such as a time filtering condition or a location filtering condition.

[0276] Optionally, the first network element may also carry a reporting condition in the first request message, which is used to instruct the data analysis network element to feedback two types of analysis information according to the reporting condition. For example, the reporting condition may be a time set by a timer, which is used to instruct the data analysis network element to feedback the first analysis information within a period of time after receiving the first request message, or to feedback the first analysis information after the first analysis information meets a preset condition, or to periodically report the first analysis information, etc.

[0277] S402: The data analysis network element obtains relevant training data.

[0278] It should be understood that in order to generate the service experience analysis information of the terminal device, the content and acquisition method of the training data acquired by the data analysis network element are similar to S302, and will not be described in detail here.

[0279] S403: Based on the acquired training data, the data analysis network element analyzes and acquires service experience analysis information corresponding to the RAT or access frequency.

[0280] It should be understood that in order to obtain the service experience analysis information corresponding to the RAT or access frequency, the training data content and acquisition method obtained by the data analysis network element are similar to S303, and will not be described here one by one. One thing to note is that steps 402 to 403 do not depend on step 401, and they have no temporal relationship with 401. In other words, the data analysis network element can obtain relevant training data and generate relevant analysis information in advance, and it is not necessary to wait until the first request message is received to perform related operations.

[0281] S404, the data analysis network element sends a first response message to the first network element, where the first response message includes first analysis information.

[0282] The first analysis information is the first analysis message corresponding to the first request message in S401.

[0283] It should be understood that S404 is similar to S305, except that S305 may need to simultaneously obtain business behavior analysis information, but here the business behavior information has been determined, so there is no need to obtain the business behavior analysis information.

[0284] S405: The first network element obtains a service establishment request message from the terminal device.

[0285] Optionally, the first network element receives a service establishment request message initiated by the AF for a terminal device, and the first network element formulates an access selection strategy based on the type of service initiated and in combination with the first analysis information obtained from the data analysis network element, so that the service experience of the service type under the target RAT or target access frequency indicated in the strategy meets preset conditions.

[0286] It should be understood that there is no sequential relationship between step 401 and step 405 in time. In one possible implementation, step 405 may occur after step 401. In another possible implementation, step 405 may also occur before step 401. That is, after a certain type of service occurs on the terminal device, the first network element sends a first request message to the data analysis network element. Preferably, the first request message includes the service type that has occurred, which is used to request the first analysis information of the corresponding service type.

[0287] S406: The first network element obtains first analysis information and determines an access information selection strategy for the terminal device.

[0288] It should be understood that S406 is similar to S306, and the only difference is that in this embodiment, the service type occurring in the terminal device has been confirmed, and therefore, there is no need to count or predict the service type occurring in the terminal device.

[0289] S407, the first network element sends first indication information to the third network element, where the first indication information includes an access information selection strategy for the terminal device determined by the first network element.

[0290] It should be understood that the method in which the first network element sends the first indication information to the third network element is similar to S307, which will not be described in detail here.

[0291] S408, based on the access information selection strategy of the terminal device sent by the first network element, the third network element determines and executes the residence strategy of the terminal device.

[0292] It should be understood that the third network element determines and executes the residence strategy of the terminal device in a method similar to S308, which will not be described in detail here.

[0293] S409: According to the instruction of the third network element, the terminal device accesses the target RAT or accesses the frequency point.

[0294] It should be understood that the method for the terminal device to access the target RAT or access the frequency point is similar to S309, which will not be described in detail here.

[0295] In the technical solution provided in the embodiment of the present application, the data analysis network element can statistically analyze the relationship between the service experience information and the wireless access information. Accordingly, the data analysis network element can assist the first network element in formulating a wireless access information selection strategy for a single terminal device, which is used to select a suitable resident RAT or resident frequency for the terminal device in different scenarios, and the strategy is formulated based on the service type that the terminal device is about to initiate or has initiated, that is, the service type of the terminal device is taken into account. The strategy is dynamically variable, so that the service experience of the terminal device can reach the preset conditions.

[0296] Figure 8 It is a flowchart of another strategy determination method provided in an embodiment of the present application.

[0297] S501, the second network element obtains second analysis information from the data analysis network element.

[0298] It should be understood that the second network element can be a network element with decision-making functions, which can provide various relevant strategies for network devices or terminal devices, for example, it can be OAM, network slice management function (NSMF), communication service management function (CSMF), etc. The second network element in this embodiment specifically involves the decision of network energy-saving strategy. The data analysis network element can be a network element with data collection, training, analysis, and reasoning functions, which can collect relevant data from network network elements, third-party service servers, terminal devices or network management systems, perform analysis and training based on relevant data, and provide data analysis information to network network elements, third-party service servers, terminal devices or network management systems. For example, the data analysis network element can be NWDAF, MDAS, etc. The data analysis network element can be a single network element, a combination of multiple network elements, or it can be co-located with the second network element or other network elements.

[0299] The second analysis information includes at least one of the following information: information related to RAT or information related to access frequency, service experience analysis information corresponding to RAT or access frequency, and service behavior analysis information.

[0300] Optionally, the meaning and content of the relevant information of the RAT or the relevant information of the access frequency point are the same as Figure 7The relevant information of the RAT or the relevant information of the access frequency in the embodiments is the same and will not be repeated here.

[0301] Optionally, the service experience analysis information corresponding to the RAT or access frequency is the same as the service experience analysis information corresponding to the aforementioned RAT or access frequency, and is not repeated here.

[0302] Optionally, the business behavior analysis information may include: business behavior analysis information at the terminal device level or business behavior analysis information of terminal devices aggregated in a network area.

[0303] Among them, the terminal device level business behavior analysis information is specifically referred to Figure 5 The business behavior analysis information at the terminal device level in the embodiment will not be repeated here; the business behavior analysis information of the terminal devices aggregated in the network area may include at least one of the following information: time information, area information, business type, priority information of the business type, probability of occurrence of the business type, duration of the business type, number of users corresponding to the business type, and proportion of users of the business type.

[0304] Optionally, the business behavior analysis information includes: business behavior statistical information or business behavior prediction information.

[0305] Optionally, the second network element obtains second analysis information from the data analysis network element, and the method includes: the second network element sends a second request message to the data analysis network element, the second request message includes at least one area information, the second request message is used to request to obtain the second analysis information corresponding to the area information, and the second network element receives a second response message sent by the data analysis network element, and the second response message includes the second analysis information. For example, the second request message is used to request the service behavior analysis information within area A, and / or the service experience analysis information corresponding to the RAT / access frequency within area A. Among them, the service behavior analysis information within area A can be the service behavior analysis information of each terminal device in area A, and can also be the aggregated service behavior analysis information within area A; the service experience analysis information corresponding to the RAT / access frequency within area A can be the service experience analysis information of the service type of each terminal device in area A under the RAT / access frequency, and can also be the service experience analysis information of the service type in area A under the RAT / access frequency.

[0306] Optionally, the second network element obtains second analysis information from the data analysis network element, and the method includes: the second network element sends a second request message to the data analysis network element, the second request message includes the service type, the second request message is used to request to obtain the second analysis information corresponding to the service type, and the second network element receives a second response message sent by the data analysis network element, and the second response message includes the second analysis information. For example, the second request message is used to request the service behavior analysis information corresponding to service type 1, and / or the service experience analysis information of service type 1 under RAT / access frequency. Among them, the service behavior analysis information corresponding to service type 1 can be the service behavior analysis information of each terminal device corresponding to service type 1, and can also be the aggregated service behavior analysis information corresponding to service type 1; the service experience analysis information of service type 1 under RAT / access frequency can be the service experience analysis information of service type 1 of each terminal device under RAT / access frequency, and can also be the service experience analysis information of service type 1 under RAT / access frequency.

[0307] Optionally, the second network element may be a core network element, a network management network element, an application server, etc., wherein the core network element includes a control plane network element or a user plane network element.

[0308] S502: The second network element determines an energy-saving strategy for the network area according to the second analysis information.

[0309] Optionally, the second network element determines an energy-saving strategy for the network area according to the second analysis information, and the method includes: the second network element determines a method for switching, power consumption control, or load transfer of the access network unit according to the second analysis information, so that the energy consumption of the network area meets a preset condition and / or the service experience corresponding to the service type meets a preset condition. For example, the energy consumption of the network area is less than a first threshold, and / or the service experience corresponding to the service type is optimal or greater than a second threshold.

[0310] The switch of the access network unit includes turning on or off the base station, access frequency point, and cell. For example, turning off the entire base station and turning on the cell corresponding to the 2600MHZ frequency point in the base station.

[0311] The power consumption control of the access network unit includes increasing or decreasing the power or energy consumption corresponding to the base station, access frequency point, and cell. For example, the power consumption corresponding to the 3.5GHZ cell is reduced, and the power consumption corresponding to the 900MHZ cell is increased.

[0312] The load transfer of access network units includes load transfer between base stations, between access frequencies, and between cells. For example, the load of cell 1 corresponding to NR is transferred to cell 2 corresponding to LTE.

[0313] It should be understood that the energy-saving strategy of the network area may include more than two operation methods such as switching, power consumption control or load transfer of the access network unit. For example, when the load of an access network unit is very low, before instructing to shut down the access network unit, the energy-saving strategy may also instruct to transfer the load of the access network unit to another access network unit.

[0314] In a possible implementation, when the second analysis information includes relevant information about RAT or relevant information about access frequency, and the relevant information about RAT or relevant information about access frequency includes a recommended RAT or recommended access frequency for at least one service type, the second network element determines the energy saving strategy of the network area according to the second analysis information, and the method includes: the second network element determines the service type of the network area, the service type of the network area refers to at least one service type that has been initiated or is to be initiated in the network area, the second network element determines the number of users or the proportion of users of the service type in the network area, and the second network element determines the switch, power consumption control or load transfer method of the access network unit according to the recommended RAT or recommended access frequency corresponding to the service type of the network area, and the number of users or the proportion of users of the service type in the network area. For example, the second analysis information includes the recommended RAT or recommended frequency for service A, service B, and service C. If the second network element determines that service A has occurred or is to occur in area 1, the second network element will determine the switch, power consumption control or load transfer method of the access network unit according to the recommended RAT or recommended frequency for service A, and the number of users or the proportion of users of service A in the network area.

[0315] In a possible implementation, when the second analysis information includes relevant information of the RAT or relevant information of the access frequency, and the relevant information of the RAT or relevant information of the access frequency includes a RAT or a recommended access frequency recommended for the terminal device level, the second network element determines the energy saving strategy of the network area according to the second analysis information, and the method includes: the second network element determines the recommended RAT or the recommended access frequency corresponding to at least one terminal device in the network area, and the second network element determines the switch, power consumption control or load transfer method of the access network unit according to the recommended RAT or the recommended access frequency corresponding to at least one terminal device in the network area. For example, the second analysis information includes the recommended RAT or the recommended frequency for each terminal device in area 1, and the second network element determines the switch, power consumption control or load transfer method of the access network unit according to the recommended RAT or the recommended frequency for each terminal device. Specifically, the second network element counts the resource demand of each RAT or access frequency according to the recommended RAT or the recommended frequency for each terminal device, and then determines how to switch, control the power consumption or transfer the load of the access network unit according to the resource demand of each RAT or the access frequency.

[0316] In a possible implementation, when the second analysis information includes relevant information of the RAT or relevant information of the access frequency, and the relevant information of the RAT or relevant information of the access frequency includes a recommended RAT or a recommended access frequency for a service type at the terminal device level, the second network element determines an energy-saving strategy for the network area based on the second analysis information, and the method includes: the second network element determines the service type that has been initiated or is to be initiated by the terminal device in the network area, the second network element determines the recommended RAT or the recommended access frequency corresponding to the service type that has been initiated or is to be initiated by the terminal device, and the second network element determines a method for switching, power consumption control, or load transfer of an access network unit based on the recommended RAT or the recommended access frequency corresponding to the service type that has been initiated or is to be initiated by the terminal device. For example, if the second analysis information includes a recommended RAT or a recommended frequency for each service type of each terminal device in area 1, the second network element determines a method for switching, power consumption control, or load transfer of an access network unit based on the recommended RAT or the recommended frequency for each service type of each terminal device. Specifically, as shown in Tables 10A and 10B below, the second network element counts the resource requirements of each RAT or access frequency based on the recommended RAT or recommended frequency for each service type of each terminal device to determine how to switch, control power consumption or load transfer the access network unit.

As shown in Tables 11A and 11B below, for example, the second analysis information includes the service experience corresponding to service A, service B, and service C under RAT or access frequency. If the second network element determines that service A has occurred or will occur in area 1, the first network element determines the target RAT or target access frequency based on the service experience corresponding to service A under RAT or access frequency, so that the service experience corresponding to service A in the network area under the target RAT or target access frequency can meet the preset conditions, and the second network element determines the number of users or the proportion of users of service A in the network area. The second network element determines the switch, power consumption control, or load transfer method of the access network unit based on the number of users or the proportion of users of service A in the network area, and the target RAT or target access frequency corresponding to service A in the network area. Similarly, if there is more than one type of service occurring in area 1, for each type of service, the second network element can determine the target RAT or access frequency corresponding to each type of service and the number of users or the proportion of users corresponding to each type of service using the same method as above. The second network element then counts the resource demand of each RAT or access frequency based on the number of users or the proportion of users corresponding to each service type in the network area, and the target RAT or access frequency corresponding to each service type, so as to determine how to switch, control power consumption or load transfer the access network unit.

As shown in Tables 12A and 12B below. For example, the second analysis information includes the service experience corresponding to each terminal device in area 1 under the RAT or access frequency. The second network element determines the target RAT or target access frequency for the service experience corresponding to the service that has occurred or is about to occur on each terminal device under the RAT or access frequency, so that the service experience corresponding to the service type that has been initiated or is about to be initiated by each terminal device under the target RAT or target access frequency can meet the preset conditions. The second network element then determines the method of switching, power consumption control or load transfer of the access network unit based on the service type that has been initiated or is about to be initiated by each terminal device, and the target RAT or target access frequency corresponding to the service type that has been initiated or is about to be initiated by each terminal device. Specifically, the second network element counts the resource demand of each RAT or access frequency based on the service type that has been initiated or is about to be initiated by each terminal device, and the target RAT or target access frequency corresponding to the service type that has been initiated or is about to be initiated by each terminal device, so as to determine how to switch, control power consumption or load transfer the access network unit.

The second network element determines the business type of the network area, and the method includes: the second network element determines the business type of the network area based on the business behavior analysis information of the terminal devices aggregated in the network area.

[0332] Optionally, the second analysis information also includes business behavior analysis information, and the business behavior analysis information includes business behavior analysis information at the terminal device level. The second network element determines the type of service that has been initiated or will be initiated by the terminal device in the network area. The method includes: the second network element determines the type of service that has been initiated or will be initiated by the terminal device in the network area based on the business behavior analysis information at the terminal device level.

[0333] Optionally, the second network element determines the energy-saving strategy of the network area based on the second analysis information and the second information, wherein the second information includes: priority information of the service type in the network area, charging policy information of the service type in the network area, user type of the terminal device in the network area, the number of connected users in the network area, the number of idle users in the network area, the resource demand of the network area, and the power consumption of the network area. The resource demand of the network area may be the overall resource demand of the network area or the resource demand at the service type level; the power consumption of the network area may be the overall power consumption of the network area or the power consumption at the service type level. The second information may come from the second network element itself or from other network elements, such as NWDAF, etc.

[0334] For example, the second network element determines based on the second analysis information that the NR resources in the network area are insufficient to support all service types in the area, but the NR resources can support high-priority service type A. The energy-saving strategy generated by the second network element indicates that there is no need to turn on other NR base stations or cells.

[0335] For example, the second network element determines based on the second analysis information that the demand for NR resources in the network area is low and a certain NR cell needs to be shut down, but there are some gold medal users in the cell. The energy-saving strategy generated by the second network element indicates that the NR cell cannot be shut down.

[0336] Optionally, the second response message may further include an applicable condition of the second analysis information, where the applicable condition of the second analysis information includes at least one of the following information: service type, user type, user identification, time information, and area information. The applicable condition of the second analysis information is used to indicate under which conditions the second information is available.

[0337] It should be understood that different analysis information in the second analysis information may have different applicable conditions. For example, the service experience analysis information corresponding to the RAT or access frequency corresponds to applicable condition 1, and the service behavior analysis information corresponds to applicable condition 2.

[0338] Optionally, when the second network element is a core network element or a network management element, the method further includes: the second network element sends the energy-saving policy of the network area to the access network element, or the second network element sends the energy-saving policy of the network area to the network management execution element. Among them, the second network element sends the energy-saving policy of the network area to the access network element, so that the access network element refers to the energy-saving policy to perform the switching, power consumption control or load transfer operations of the access network unit, thereby achieving the purpose of saving the energy consumption of the access network under the premise of ensuring the service experience in the network area. Similarly, the second network element sends the energy-saving policy of the network area to the network management execution element, so that the network management execution element refers to the energy-saving policy to perform the switching, power consumption control or load transfer operations of the access network unit, thereby achieving the purpose of saving the energy consumption of the access network under the premise of ensuring the service experience in the network area.

[0339] Optionally, the second network element sends the applicable conditions of the energy-saving strategy of the network area to the access network element or the network management execution network element, including at least one of the following information: service type, user type, user identification, time information, and area information.

[0340] Optionally, when the second network element is an access network element, the method further includes: the second network element executes an energy-saving strategy for the network area, that is, a method for executing a switch, power consumption control, or load transfer of the access network element. In other words, after the access network element obtains the second analysis information from the data analysis network element, it generates an energy-saving strategy for the network area with reference to the second analysis information and executes the energy-saving strategy.

[0341] Fig. 9 This is an interactive schematic diagram of another strategy determination method provided in an embodiment of the present application.

[0342] S601, the second network element sends a second request message to the data analysis network element.

[0343] It should be understood that the method in which the second network element sends the second request message to the data analysis network element is similar to that in S501, and will not be repeated here.

[0344] S602: The data analysis network element obtains training data.

[0345] Optionally, to analyze the business behavior of terminal devices in the area, the training data collected by the data analysis network element is similar to Table 6 above. The difference is that the training data collected here is information obtained for all terminal devices or multiple terminal devices in the area, not just information obtained for a single terminal device.

[0346] Optionally, to analyze the service experience based on wireless access information, the service data collected by the data analysis network element is the same as that in Table 7. It should be noted that the service data collected here is also information obtained for all terminal devices or multiple terminal devices in the area.

[0347] S603: Based on the acquired training data, the data analysis network element analyzes and acquires service experience analysis information corresponding to the RAT or access frequency.

[0348] It should be understood that the data analysis network element analysis to obtain the service experience analysis information corresponding to the RAT or access frequency is the same as the aforementioned acquisition method, and will not be repeated here.

[0349] S604, based on the acquired training data, the data analysis network element analyzes and acquires business behavior analysis information.

[0350] Here, the business behavior analysis information refers to data analysis information that can reflect the business usage or regularity of one or more terminal devices (such as terminal devices of the same priority or only gold-medal terminal device groups) or all terminal devices in the entire network or network area.

[0351] Optionally, the business behavior analysis information of the terminal device may include: business behavior analysis information at the terminal device level or business behavior analysis information of terminal devices aggregated in a network area.

[0352] Optionally, the terminal device-level service behavior analysis information may include: at least one of the terminal device identification, time information, area information, service type, service type priority information, service type occurrence probability, and service type duration. The service type may be one or more service types. The terminal device-level service behavior analysis information is shown in Table 9.

[0353] Optionally, the service behavior analysis information of the terminal devices aggregated in the network area may include: the service type in the network or area, the number of users corresponding to the service type, the proportion of the number of users corresponding to the service type, the location where the service occurs, the time when the service is initiated, the duration of the service, the probability of the service type occurring, and at least one of the priority information of the service. Among them, the service type may be one or more service types, and the service behavior analysis information at the terminal device level aggregated in the network area is shown in Table 13.

[0354] Table 13

[0355]

[0356] It should be understood that each item of information in the above table is not necessarily necessary. For example, the area information is optional. When there is no area information, Table 12 represents the service behavior analysis information of the terminal devices of the entire network.

[0357] Optionally, the business behavior analysis information includes: business behavior statistical information or business behavior prediction information.

[0358] Optionally, the data analysis network element determines the business behavior prediction information of the terminal device, which is the same as the aforementioned acquisition method and will not be repeated here.

[0359] It should be understood that there is no temporal order relationship between S601 and S602 to S604 , and this embodiment is only used as an example and does not limit the order.

[0360] S605, the data analysis network element sends a second response message to the second network element, and the second response message may include second analysis information.

[0361] The second analysis information is the analysis message corresponding to the second request message in S601.

[0362] Optionally, the second analysis information includes at least one of the following information: RAT or access frequency information, service experience analysis information corresponding to the RAT or access frequency, and service behavior analysis information.

[0363] It should be understood that the second network element can receive the second analysis information multiple times, and each second analysis information may include RAT or access frequency information, and one of the service experience analysis information or service behavior analysis information corresponding to the RAT or access frequency.

[0364] Optionally, the second response message may further include an applicable condition of the second analysis information, where the applicable condition of the second analysis information includes at least one of the following information: service type, user type, user identification, time information, and area information. The applicable condition of the second analysis information is used to indicate under which conditions the second information is available.

[0365] It should be understood that different analysis information in the second analysis information may have different applicable conditions. For example, the service experience analysis information corresponding to the RAT or access frequency corresponds to applicable condition 1, and the service behavior analysis information corresponds to applicable condition 2.

[0366] S606: The second network element determines an energy-saving strategy for the network area based on the second analysis information.

[0367] It should be understood that the second network element determines the energy-saving strategy of the network area based on the second analysis information, which is similar to the S502 method and will not be described in detail here.

[0368] In a possible implementation, the second network element determines the number of users or user proportion of a certain service type in the area (the proportion of users using the service to the total number of users in the area) based on the service behavior analysis information of the terminal devices in the area, and determines the RAT or access frequency that can make the service experience of the service type meet the preset conditions based on the service experience analysis information based on the wireless access information, for example, it can be the RAT or access frequency that makes the service experience the best. Based on the above-obtained information, combined with the demand of the service for network equipment resources or the energy consumption information of the service, the second network element can determine the RAT / frequency type required for the service type in the area and the amount of its resource usage.

[0369] Similarly, for other types of services occurring in the area, the second network element can use the same method to determine the RAT or access frequency type and the amount of resource usage required for other types of services. Finally, for the area, the second network element can statistically calculate the resource demand for each RAT or each frequency, for example, the resource demand for NR / 2.6GHZ in the area, so as to determine whether the corresponding RAT or access frequency can be turned off or turned on, or whether the load of a RAT or access frequency needs to be transferred to another RAT or access frequency, or whether the power consumption corresponding to a RAT or access frequency needs to be increased or reduced.

[0370] For example, the second analysis information obtained by the second network element from the data analysis network element is as shown in Table 14.

[0371] Table 14

[0372]

[0373] Assuming that there are 100 NR network equipment units, 50 eLTE units, and 90 LTE units in the current network area, according to the above analysis of the network equipment resource demand, in a preferred implementation, the second network element can instruct the network management execution unit or the access network element to shut down 20 redundant NR units to save energy. At the same time, the second network element can instruct the network management execution unit or the access network element to schedule 10 eLTE units to balance the load of the LTE unit, for example, using the air interface virtualization technology to convert the eLTE unit into an LTE unit; or, the second network element instructs the LTE base station to transfer the overloaded terminal device to the eLTE base station, for example, the LTE base station can transfer the access terminal device to the eLTE base station by redirection or switching. Among them, before shutting down the redundant NR units, if the terminal equipment is not distributed only in 80 NR units, but distributed in more than 80 NR units, but the load of some NR units is very low, then preferably the second network element can also first concentrate the terminal equipment to the 80 NR units actually required by the load transfer method, and then shut down the redundant NR units.

[0374] In another possible implementation of this embodiment, the data analysis network element sends to the second network element not the service behavior analysis information of the terminal devices aggregated in the area as shown in Table 12, but the service behavior analysis information at the terminal device level (as shown in Table 6). The second network element itself performs data analysis to obtain intermediate result 1: service behavior analysis information of the terminal devices aggregated in the area (as shown in Table 12). Similarly, the service experience analysis information corresponding to the RAT or access frequency sent by the data analysis network element to the second network element may not be based on the service type level, but on the terminal device level. In this way, the second network element itself performs further analysis to obtain intermediate result 2: service experience analysis information corresponding to the RAT or access frequency at the service type level. Finally, the second network element generates an energy-saving strategy for the network area based on the above two intermediate results generated by itself.

[0375] In another possible implementation, the data analysis network element sends to the second network element the service experience corresponding to the RAT or access frequency at the terminal device level and the service behavior analysis information at the terminal device level. The second network element itself can also directly generate energy-saving strategies for the network area without generating intermediate results.

[0376] It should be understood that when the second network element determines the above energy-saving strategy, it is based on the business behavior and business experience of the terminal devices in the network area to ensure that the number or load of NR or NR high-frequency terminal devices is as small as possible, so that NR or NR high frequency is turned off as much as possible to save energy without affecting the business experience of the terminal devices in the area.

[0377] S607, the second network element sends the determined energy-saving strategy of the network area to the fourth network element for execution.

[0378] It should be understood that the second network element sending the determined energy-saving strategy of the network area to the fourth network element is similar to the method described in S502, and will not be described in detail here.

[0379] The present application also provides a method for determining a service type, which may include:

For example, if the data analysis network element determines that terminal device 1 belongs to the Kth category of terminal devices, and the data analysis network element obtains that terminal device 2 in the Kth category of terminal devices has initiated or is about to initiate service A, then the data analysis network element predicts that terminal device 1 will also initiate service A. Furthermore, the data analysis network element also predicts the scenario in which terminal device 1 initiates service A based on the scenario in which terminal device 2 initiates service A. For example, if terminal device 2 initiates service A at 10 o'clock on Monday, then terminal device 1 may also initiate service A at 10 o'clock on Monday or other relevant times.

[0390] Optionally, the data analysis network element determines the user portrait classification information to which a single terminal device belongs, and the method includes: the data analysis network element collects network behavior data, business behavior data, and business attribute data at the terminal device level.

Among them, the user portrait classification model may also be a user portrait feature. For example, the data analysis network element determines the portrait classification information of the single terminal device by calculating the Euclidean distance between the above-mentioned data features of the single terminal device and the user portrait features.
