Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, when an NWDAF provides network data analysis services for other network functional entities through interaction with other network functional entities based on an artificial intelligence algorithm, the NWDAF receives a network data analysis request of an NF, collects network data from one or more NFs according to the request, analyzes the collected data by using the artificial intelligence algorithm to obtain network analysis information (for example, statistical and/or predictive information of network performance or service experience), and returns the network analysis information to the NF requesting the analysis information. There is no systematic solution for when the NF requests network data analysis information, such as trigger conditions, from the NWDAF.
Generally, the NF determines to request network data analysis information from the NWDAF depending on event reports and/or local policies of other NFs. Meanwhile, the NWDAF generally initiates acquisition and analysis of network data after receiving a network data analysis request of the NF, which results in that the requirement of real-time analysis cannot be met. Furthermore, while the NWDAF may collect data and/or perform data analysis in advance, there is no systematic solution to how to collect data and/or analysis in advance, such as trigger conditions, which types of data collection and/or analysis to perform. That is, target data acquisition and/or analysis has certain unpredictability and unpredictability, and lacks uniform control, so that the signaling and data volume related to network data analysis/acquisition are large, the real-time performance is low, and the practicability and efficiency of network data analysis are reduced.
Therefore, embodiments of the present application provide a network analysis method, apparatus, and storage medium to solve the problem that target data acquisition and/or analysis in the current method has certain unpredictability and unpredictability, and improve the efficiency of network data analysis.
The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
The technical scheme provided by the embodiment of the application can be suitable for various systems, particularly 5G systems. For example, the applicable system may be a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a long term evolution (long term evolution, LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an LTE-a (long term evolution) system, a universal mobile system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Mobile Access (WiMAX) system, a New Radio network (NR 5) system, etc. These various systems include terminal devices and network devices. The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5GS), and the like.
The terminal device referred to in the embodiments of the present application may refer to a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application. Since the terminal device forms a network capable of supporting communication with other network devices (e.g., a core network device, an access network device (i.e., a base station)), the terminal device is also considered as a network device in the present invention.
In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Furthermore, it should be appreciated 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.
