Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

At present, when the NWDAF provides network data analysis service for other network function entities through interaction with other network function entities based on an artificial intelligence algorithm, the NWDAF comprises receiving a network data analysis request of NFs, collecting network data from one or more NFs according to the request, analyzing the collected data by utilizing the artificial intelligence algorithm to obtain network analysis information (such as statistics and/or prediction information of network performance or service experience), and returning the network analysis information to NFs requesting the analysis information. There is no systematic solution for when NF requests network data analysis information, such as trigger conditions, from NWDAF.

Generally, NFs determine to request network data analysis information from NWDAFs based on event reports and/or local policies of other NFs. Meanwhile, NWDAF generally initiates collection and analysis of network data after receiving a network data analysis request of NF, which results in a failure to meet the requirement of real-time analysis. Furthermore, while NWDAF may collect data and/or perform data analysis in advance, there is no systematic solution for how to collect data and/or analyze in advance, such as trigger conditions, which types of data collection and/or analysis to perform. That is, the target data collection and/or analysis has a certain unpredictability and unpredictability, and lacks uniform control, which may cause large signaling and data volume related to network data analysis/collection, and low real-time performance, thereby reducing the practicability and efficiency of network data analysis.

Therefore, the embodiment of the application provides a network analysis method, a device and a storage medium, so as to solve the problem that the target data acquisition and/or analysis in the current method has a certain unpredictability and an unpredictability, and improve the efficiency of network data analysis.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

The technical scheme provided by the embodiment of the application can be suitable for various systems, in particular to a 5G system. For example, suitable systems may be global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) universal packet Radio service (general packet Radio service, GPRS), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), long term evolution-advanced (long term evolution advanced, LTE-a), universal mobile system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX), 5G New air interface (New Radio, NR), and the like. Terminal devices and network devices are included in these various systems. Core network parts such as evolved packet system (Evloved Packet System, EPS), 5G system (5 GS) etc. may also be included in the system.

The terminal device according to the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem, etc. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like.

Since the terminal device forms a communication-capable network together with other network devices, such as core network devices, access network devices (i.e. base stations), the terminal device is also regarded as a network device in the present invention.

In the embodiment of the application, the term "and/or" describes the association relationship of the association objects, which means that three relationships may exist, for example, a and/or B may be represented: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Furthermore, it is to be understood that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Fourth, when the NF entity is a User Equipment (UE), the PCF entity sends the network analysis control information to the UE through a UE policy control procedure.

Specifically, the PCF entity sends the network analysis control information to the ue through a ue policy control procedure, including any one of the following:

1, as shown in fig. 5-1, the PCF entity sends a communication message transmission service request to the AMF entity.

Specifically, the communication message transmission service request carries network analysis control information, so that the AMF entity forwards the network analysis control information to the user equipment through a downlink non-access layer transmission message.

That is, the PCF entity may send a Communication message transmission service request (namf_communication_n1n2message transfer) carrying network analysis control information to the AMF entity, and the AMF entity may forward the network analysis control information carried in a downlink non-access stratum transmission message (DL NAS TRANSPORT) to the user equipment, so that the user equipment can determine when to initiate a network analysis request to NWDAF and/or perform data acquisition according to the network analysis control information.

Of course, the PCF entity also needs to receive the ue policy control_create request (npcf_ue policy control_create) sent by the AMF entity before sending the ue policy control_create response to the AMF entity.

3, as shown in fig. 5-3, the PCF entity sends a user equipment policy control update response to the AMF entity.

Of course, the PCF entity also needs to receive the ue policy control update request (npcf_ue policy update_create) sent by the AMF entity before sending the ue policy control update response to the AMF entity.

4, PCF entity sends user equipment strategy control update notice to AMF entity.

Specifically, the network analysis control information is carried in the user equipment policy control update notification, so that the AMF entity forwards the network analysis control information to the user equipment through downlink non-access layer transmission.

The PCF may also send a user equipment network analysis control related policy control request trigger (Policy Control Request Trigger) condition to the AMF by sending a user equipment policy control setup response (npcf_uepolicy control_create response) or a user equipment policy control Update response (npcf_uepolicy control_update response) or a user equipment policy control Update notification (npcf_uepolicy control_update notification) service request to the AMF. When the trigger condition of the policy control request related to the user equipment network analysis control is met, the AMF entity initiates the user equipment policy control related request to the PCF entity, thereby triggering the PCF entity to send the (updated) user equipment policy to the user equipment, wherein the (updated) user equipment network analysis control information can be contained.

Thus, when the NF entity is an AMF entity, an SMF entity, an NWDAF entity or a user equipment, the PCF entity may send the network analysis control information to the NF entity through the corresponding control flow, so that the NF entity obtains the network analysis control information.

It should be noted that the above procedure may be performed in the user equipment registration, PDU session establishment/modification, service-specific parameter setting procedure, or the PCF entity decides to initiate according to other triggers (e.g. analysis information from NWDAF, local configuration), which is not specifically limited herein.

Furthermore, optionally, before the PCF entity sends the network analysis control information to the NF entity, the PCF entity may further receive specific target analysis control information sent by an Application Function (AF) entity, wherein the specific target analysis control information includes control information for data acquisition and/or analysis of a specific target, the specific target includes a specific service and/or a specific application, and then determine the network analysis control information of the specific service and/or the specific application based on the specific target analysis control information.

I.e. the AF entity may provide the PCF entity with specific target analysis control information (including control information for analysis and/or data collection of specific services or applications). Thereby enabling the PCF entity to determine network analysis control information for the service or application based on the information.

Specifically, when the PCF entity receives the specific target analysis control information sent by the application function AF entity, any one of the following manners may be included:

first, the PCF entity receives specific target analysis control information forwarded by the AF entity through a network capability opening function (NEF) entity and a Unified Database (UDR).

Specifically, the AF entity may forward the specific target analysis control information to the PCF entity through the NEF entity and the UDR. At this time, the AF entity may send a service parameter setup request (nnef_serviceparameter_create) or a service parameter Update request (nnef_serviceparameter_update) carrying specific target analysis control information to the NEF entity to send the specific target analysis control information to the NEF entity; then, the NEF entity stores the specific target analysis control information to the UDR; finally, the UDR informs the PCF entity of the specific target analysis control information, so that the PCF entity determines network analysis control information for the service or application according to the specific target analysis control information.

Secondly, the PCF entity receives the specific target analysis control information forwarded by the AF entity through the NEF entity.

Specifically, the AF entity may send the specific target analysis control information to the PCF entity through the NEF entity. At this time, the AF entity may send an application policy establishment request (nnef_applypolicjcreate) or an application policy Update request (Nnef applypolicjupdate) carrying specific target analysis control information to the NEF entity, so as to send the specific target analysis control information to the NEF entity; then, the NEF entity sends a policy authorization setup request (npcf_policy authorization_create) or a policy authorization Update request (npcf_policy authorization_update) carrying the specific target analysis control information to the PCF entity, so that the PCF entity determines network analysis control information for the service or application according to the specific target analysis control information.

Thirdly, the PCF entity receives the specific target analysis control information directly sent by the AF entity.

Specifically, if the AF entity belongs to a trusted AF entity, for example, the AF entity is an AF deployed by an operator in a network, the AF entity may directly send an npcf_policy authorization_create or npcf_policy authorization_update service request to the PCF, where specific target analysis control information is carried, so as to send the specific target analysis control information to the PCF entity.

In this way, by any of the above ways, it is achieved that the PCF entity determines network analysis control information for a specific service and/or a specific application based on the information provided by the AF entity.
