[0002] The present application relates to the field of communication technologies, and in particular to an information interaction method, device, and processor-readable storage medium. Background Art

[0003] In the next generation Radio Access Network (RAN) architecture, the RAN may include multiple radio network functions, some of which may provide UE-related services for the core network.

[0004] In related technologies, only one pair of devices can directly exchange information between the core network and the RAN, that is, only the next generation Node B Central Unit (gNB-CU) in the RAN and the Access and Mobility Management Function (AMF) in the core network interact. Summary of the Invention

[0005] Based on this, it is necessary to provide an information interaction method, device and processor-readable storage medium to address the above technical problems, which can enable information interaction between wireless network functions and the core network.

[0006] In a first aspect, an embodiment of the present application provides an information interaction method, applied to a first network function in a wireless access network, the method comprising:

[0007] Determine a target second network function; the target second network function is a network function in the radio access network used to provide a UE-related target service to the core network.

[0008] In the technical solution provided in the embodiment of the present application, the target second network function is determined by the first network function, which is equivalent to determining, for the core network, a network function from the wireless access network that can provide a target service related to the UE through the first network function.

In this way, even if there are multiple wireless network functions in the wireless access network, the core network can find the network function that provides the target service in the wireless access network, thereby realizing information interaction between the core network and the network functions in the wireless access network.

[0037] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0039] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The technical background of this application is first described below.

[0042] The Next Generation Radio Access Network (NG-RAN) is called the next generation radio access network or 5G radio access network because it can accommodate multiple widely used radio access technologies and meet the various performance requirements of 5G systems. The NG-RAN includes one or more next-generation base stations (gNBs). A gNB consists of a gNB Central Unit (gNB-CU) and one or more gNB Distributed Units (gNB-DUs).

[0043] The gNB-CU carries the gNB's Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) protocols. It supports network functions such as UE radio access control, UE connection control, radio bearer control, mobility management, and paging. The gNB-DU carries the gNB's Radio Link Control (RLC), Media Access Control (MAC), and physical layer, with some of its operations controlled by the gNB-CU.

[0044] In addition to the 5G radio access network, the 5G system also includes the 5G core network (also known as 5GC). The 5GC includes the Access and Mobility Management Function (AMF), the Session Management Function (SMF), and the User Plane Function (UPF). The AMF and SMF can each provide services through their service-based interfaces, and the AMF and SMF exchange information through service-based interfaces.

[0045] Figure 1 illustrates the overall NG-RAN architecture. The gNB and 5GC are connected via the logical NG interface, and gNBs are connected to each other via the logical Xn-C interface. Within the gNB, the gNB-CU and gNB-DU are connected via the protocol interface F1. The NG interface is divided into the NG-C interface and the NG-U interface. For the user plane, the NG-U interface between the gNB-CU and the UPF transmits UE user plane data. For the control plane, the NG-C interface between the gNB-CU and the AMF transmits signaling. Information exchanged between the gNB-CU and the SMF is transparently forwarded via the NG-C interface and the AMF's service-based interface.

[0046] In related technologies, only one pair of devices can directly exchange information between the core network and the RAN: the AMF in the core network and the gNB-CU in the RAN. The core network does not exchange information with any base station logical nodes in the RAN other than the gNB-CU. However, the NG-RAN may include multiple radio network functions, each of which can provide different services related to different UEs to the core network. For example, the introduction of a radio data transmission management network function in the RAN can provide services that control / manage UE data transmission in the radio access network, thereby providing the core network with services for transmitting UE data in the radio access network.

[0047] However, when multiple radio network functions are introduced into the RAN, numerous challenges arise. For example, when the core network needs to interact with a network function in the access network, how can the core network locate the network function providing a specific service in the radio access network? Therefore, how to facilitate information exchange between the core network and the network functions in the radio access network becomes a technical problem that needs to be solved urgently. Based on this, the embodiments of the present application provide an information exchange method, apparatus, and processor-readable storage medium that can address the aforementioned issues. Of course, the technical solutions provided in the embodiments of the present application are not limited to addressing the aforementioned issues and also have other technical effects, as described in detail in the following embodiments.

[0048] Before describing the embodiments of the present application, the application scenarios of the embodiments of the present application are described first.

[0049] The information interaction method provided in the embodiments of the present application can be, but is not limited to, applicable to 5G and above systems, such as 6G systems, etc. As shown in FIG2 , taking the application scenario of a 5G system as an example, the application scenario includes a radio access network, a core network, and a user equipment (UE). The radio access network includes multiple radio network functions (also directly referred to as network functions), and the multiple radio network functions can be divided into a first network function and multiple second network functions (only the first network function and the second network function are shown in FIG2 ). The first network function, the second network function, the core network, and the UE can communicate with each other in pairs.

[0050] UE includes, but is not limited to, terminals or network devices. Terminals include, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices include smart speakers, smart TVs, smart air conditioners, and smart car devices. Portable wearable devices include smart watches, smart bracelets, and head-mounted devices. Network devices include base stations, wireless access points, and other IoT devices.

[0051] This application provides embodiments with a first network function in a radio access network, a target second network function in the radio access network, a core network, and a UE as execution entities. The embodiment with the first network function in the radio access network as the execution entity is first described below.

[0052] In one embodiment, an information interaction method is provided, which is applied to a first network function in a wireless access network. As shown in FIG3 , the method may include the following steps:

[0053] S101, determining a target second network function; the target second network function is a network function in a radio access network used to provide a UE-related target service to a core network.

[0054] The wireless access network includes multiple network functions. In the embodiment of the present application, the first network function and the target second network function are both network functions in the wireless access network. In the embodiment of the present application, whether in the access network or the core network, the network functions mentioned refer to network functions with processing functions, which define functional behaviors and interfaces. These network functions can also be replaced by logical nodes or base station logical nodes. The network function can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, such as on a cloud infrastructure.

[0055] The first network function is any one or more network functions in the radio access network. For example, an existing network function in the radio access network may be updated to become the first network function, or a new network function may be added to the radio access network as the first network function.

[0056] The other network functions in the radio access network, except the first network function, are generally referred to as second network functions. These second network functions can provide multiple services related to multiple UEs to the core network, and the target second network function is the network function among these second network functions that can provide the core network with the target service related to the UE.

[0057] In one embodiment, the first network function or the second network function includes at least one of the following functions: a function for UE data transmission management; a function for UE data transmission; a function for sensing; a function for positioning; a UE wireless connection control function; a UE mobility management function; a control plane data transmission function; a paging function; and other functions related to user plane data transmission.

[0058] Of course, the above is only an example. In the embodiments of the present application, it is not excluded that the first network function or the second network function also carries / supports / includes other functions. For example, the first network function may also include a UE wireless connection control / management function.

[0059] Taking the above-mentioned function for UE data transmission management as an example, in one implementation, the function for UE data transmission management may be one or more of controlling the establishment / modification / release / deletion of a channel for transmitting UE data between the UE and the wireless access network, controlling the establishment / modification / release / deletion of a channel for transmitting UE data between the wireless access network and the core network in the wireless access network, and managing / controlling UE data transmission resources.

[0060] That is, the function for UE data transmission management may be to manage UE data transmission between the UE and the core network, to manage UE data transmission between the UE and the radio access network, or to manage UE data transmission between the radio access network and the core network.

[0061] Among them, the management implemented by the functions for UE data transmission management may include the management of transmission channels, such as the establishment, modification, release and deletion of transmission channels; or, the management implemented includes the control / management of transmission resources, such as the configuration, mapping and scheduling of transmission resources, etc.

[0062] Optionally, the above-mentioned UE data includes data between the UE and the data network and / or data between the UE and the network function. The function for UE data transmission provides a service for transmitting UE data. The function for perception provides a service for perception. The function for positioning provides a service for UE location. Among them, the data network can be, for example, an operator service, Internet access or a third-party service. The data network can also be, for example, a multimedia subsystem (IP Multimedia Subsystem, IMS), an industry or factory-specific data network, etc. Generally, the data between the UE and the data network can be transmitted through a PDU (Protocol Data Unit) session. Among them, between the UE and the network function refers to the data transmitted between the UE and the network function, and between the UE and the data network refers to the data transmitted between the UE and the data network.

[0063] In an embodiment of the present application, a first network function in a radio access network is used to determine a target second network function in the radio access network that provides a UE-related target service to a core network, and enables the core network to obtain information about the network function so that the core network can directly interact with the target second network function to provide service-related information. Therefore, the target second network function refers to a network function that can provide a UE-related target service. Because the target second network function is any one or more network functions in the radio access network, the UE-related services that can be provided by different network functions and the number of UE-related services that can be provided are not necessarily the same. Therefore, based on the functions that can be provided by each second network function in the radio access network, in one embodiment, the UE-related target service may include one or more of a plurality of services such as a service for managing / controlling UE data transmission resources, a service for UE data transmission, a service for UE location, and a perception service.

[0064] For example, when the target service is a service for managing / controlling UE data transmission resources, the target second network function is the network function for the UE data transmission management function. Similarly, when the target service is a perception service, the target second network function can be the network function responsible for the perception function.

[0065] In the embodiment of the present application, the first network function may determine the target second network function by polling at a preset frequency, or by receiving an instruction sent by the core network or the UE, or by detecting a request from the core network for information interaction. This embodiment of the present application is not limited to this.

[0066] In the embodiment of the present application, determining the target second network function through the first network function is equivalent to determining, for the core network, through the first network function, a network function from the wireless access network that can provide a target service related to the UE. In this way, even if there are multiple wireless network functions in the wireless access network, the core network can find the network function in the wireless access network that provides the target service, thereby realizing information interaction between the core network and the network functions in the wireless access network.

[0067] In the embodiments of the present application, there are multiple ways for the first network function to determine the target second network function. One of the ways is described below. As shown in Figure 4, based on any of the above embodiments, in one embodiment, the process of the first network function determining the target second network function includes the following steps:

[0068] S201: Obtain information of at least one second network function in a radio access network and information of UE-related services provided by the at least one second network function.

[0069] Before the first network function determines the target second network function, it needs to obtain information about one or more second network functions in the radio access network, as well as information about UE-related services that can be provided by these second network functions.

[0070] Optionally, in the embodiment of the present application, the information of the second network function includes but is not limited to address information of the second network function or identification information of the second network function.

[0071] For example, address information includes but is not limited to an Internet Protocol address or a physical address, etc. Identification information includes but is not limited to letters, numbers, or a combination of letters and numbers, etc.

[0072] The information about the UE-related services provided by the at least one second network function can be understood as indicating which UE-related services the second network function can provide. That is, the purpose of this information is to distinguish which services are available. Information that can refer to or distinguish specific services is sufficient. For example, the information about the UE-related services provided by the at least one second network function can include an identifier of the UE-related service, an identifier of the type of the UE-related service, an identifier of the service, an identifier of the type to which the service belongs, a name of the service, a name of the type to which the service belongs, and the like.

[0073] In addition, in an embodiment of the present application, one or more second network functions may provide one or more UE-related services. In one embodiment, the UE-related services provided by the second network function may include, from a corresponding relationship perspective, one second network function providing one UE-related service, one second network function providing multiple UE-related services, multiple second network functions providing one UE-related service, multiple second network functions providing multiple UE-related services, and the like.

[0074] Therefore, in the embodiment of the present application, the determined target second network function includes but is not limited to one network function. For example, when the target service related to the UE is jointly provided by multiple second network functions, the target second network function corresponds to multiple second network functions; naturally, when the target service related to the UE is provided by one second network function, the target second network function may be only the one second network function.

[0075] S202: Determine a target second network function according to information of a UE-related service provided by at least one second network function.

[0076] In the above steps, after the first network function obtains information about at least one second network function in the radio access network and information about UE-related services provided by at least one second network function, it is equivalent to the first network function having pre-knowledge of the UE-related services that each second network function can provide. The first network function can then determine a target second network function from multiple second network functions based on this information.

[0077] The UE-related services that each second network function can provide correspond to the services that it can provide to the core network. For example, if the second network function is a radio data transmission management network function in a radio access network, the second network function is used to provide services for controlling / managing UE data transmission in the radio access network, so that the second network function can provide services for transmitting UE data in the radio access network to the core network, or the second network function can provide services for controlling / managing UE data transmission in the radio access network to the core network.

[0078] It should be noted that, in the embodiments of the present application, the process of the first network function obtaining information about the second network function and information about at least one UE-related service provided by the second network function, and the process of the first network function determining the target second network function based on the information about the UE-related service provided by the second network function can be two independently implemented processes. It is not necessary to execute process S202 after executing process S201.

[0079] In an embodiment of the present application, the first network function determines the target second network function based on information about UE-related services that can be provided by at least one second network function in the wireless access network, and the information about the UE-related services can clearly indicate the UE-related service identifiers or type identifiers that can be provided by each second network function, thereby improving the accuracy of the first network function in determining the target second network function.

[0080] Based on the above embodiment, in one embodiment, the process of the first network function determining the target second network function based on information about a UE-related service provided by at least one second network function includes: determining the second network function that can provide the UE-related target service as the target second network function.

[0081] Based on the information about the UE-related services provided by the at least one second network function, the first network function can obtain in advance the UE-related services that can be provided by the at least one second network function in the radio access network. Therefore, the first network function can directly, quickly, and accurately screen out a target second network function that can provide the UE-related target service from the at least one second network function, thereby improving the efficiency and accuracy of determining the target second network function.

[0082] In another feasible embodiment, the above-mentioned determining the target second network function based on the information of the UE-related service provided by at least one second network function includes: determining a second network function among the at least one second network function that can provide the UE-related target service and meets the preset conditions as the target second network function.

[0083] In the embodiment of the present application, when determining the target second network function, in addition to considering that it must be able to provide the UE-related target service, it is also possible to consider whether each second network function meets the preset conditions, and determine the network function that meets both conditions as the target second network function.

[0084] The following describes the content that meets the pre-condition.

[0085] In one embodiment, satisfying the preset condition includes at least one of the load satisfying the preset load condition and being able to satisfy relevant characteristics of the target service.

[0086] That is, the first network function determines, among at least one second network function, a network function that can provide a UE-related target service and whose load meets a preset load condition as a target second network function.

[0087] Alternatively, the first network function determines, among at least one second network function, a network function that can provide a UE-related target service and can meet relevant characteristics of the target service as a target second network function.

[0088] Alternatively, the first network function determines as the target second network function a network function among at least one second network function that can provide a UE-related target service, whose load satisfies a preset load condition, and can meet the relevant characteristics of the target service.

[0089] In actual applications, the second network function, as a processing node in the wireless access network, often needs to process multiple events at the same time. Therefore, when the load of some second network functions themselves is too large, there is a risk of being unable to provide target services to the core network. Therefore, the load meets the preset load conditions mainly to constrain the current remaining load bearing capacity of the target second network function to complete the provision of target services to the core network.

[0090] For example, the load condition may be a load threshold, and satisfying the load condition means that the current load of the target second network is less than the load threshold. This ensures that the current remaining load of the target second network function is sufficient to provide the target service to the core network, thereby reducing the risk that the target second network function cannot provide the target service.

[0091] In addition, in some cases, the target second network function is able to provide the target service related to the UE and also needs to meet the relevant characteristics of the target service. The relevant characteristics require that the target second network function is not only able to complete the provision of the target service, but also needs to meet some additional service requirements when providing the target service.

[0092] Based on this, when determining the target second network function, the first network function also needs to consider the relevant features of whether each second network function can provide the target service.

[0093] Optionally, the relevant characteristics of the target service may be sent by the core network to the first network function; or, the relevant characteristics of the target service may be sent by the UE to the first network function. The embodiment of the present application does not limit the functional entity that sends the relevant characteristics of the target service.

[0094] In combination with the previous embodiments, it can be seen that the target service can be any UE-related service, such as a service for managing / controlling UE data transmission resources, a service for UE data transmission, a service for UE location, a perception service, etc.

[0095] In one embodiment, when the target service is a service for UE data transmission resource management or a service for UE data transmission, the relevant characteristics of the target service may be one or more of the slice information to which the UE data belongs; the quality information of the UE data transmission; and the security information of the UE data transmission.

[0096] In another embodiment, when the target service is a UE location service, the relevant characteristics of the target service include UE location service quality information.

[0097] In another embodiment, when the target service is a perceived service, the relevant characteristics of the target service include perceived service quality information.

[0098] For example, taking the slice information to which the relevant feature is the UE data as an example, if the UE data belongs to a certain slice, satisfying the relevant feature can be understood as the target second network function must be able to support the slice.

[0099] For another example, the relevant feature is the quality information of UE data transmission, which means that when providing the target service this time, the UE data transmission can meet a required transmission quality, and the target service that the target second network function can provide must meet the transmission quality.

[0100] Therefore, whether it is the slice information of the UE data, the quality information of the UE data transmission, or the security information of the UE data transmission, the UE location service quality information and the perceived service quality information, they all represent that the target second network function must meet these additional quality or security requirements.

[0101] In the embodiment of the present application, when determining the target second network function, the first network function not only considers the ability to provide the target service, but also considers other additional requirements required for providing the target service, as well as the load of the second network function itself. This is equivalent to the first network function comprehensively considering multiple dimensions to screen the target second network function when determining the target second network function, thereby further improving the accuracy of the target second network function.

[0102] Since the target second network function represents a network function that can provide a target service related to the UE, the first network function needs to determine the target service related to the UE before determining the target second network function.

[0103] The following describes a process in which the first network function determines a target service related to the UE.

[0104] In one embodiment, before determining the target second network function, the method further includes: receiving first information sent by the core network or the UE, and determining a target service related to the UE according to the first information.

[0105] In this embodiment of the present application, the first information can be sent by different functional entities, that is, the first information can be sent by the core network to the first network function, or it can be sent by the UE to the first network function. After receiving the first information, the first network function can determine the target service related to the UE based on the first information. In this way, by sending the first information to the first network function through the core network or the UE, the first network function determines the target service, allowing the first network function to quickly learn about the target service related to the UE.

[0106] Optionally, the first information indicates a target service related to the UE; or the first information indicates a target service of the UE; or the first information indicates a target function of the UE. Optionally, the first information includes at least one of the following: an identifier of the target service; an identifier of the type of the target service; an identifier of the target service; an identifier of the type of the target service; an identifier of the target function; an identifier of the type of the target function; or an identifier of the UE. The distinction between a service and a service in the target service and target service can be understood as follows: a service is a service required by the UE that can be provided to the core network, while a service is a specific service that the UE itself can perform.

[0107] Whether it is the core network or the UE, the first information sent to the first network function can directly carry the identifier or type identifier of the target service to clearly indicate the required target service.

[0108] For example, the first information is sent by the core network, and the first information may indicate a target service related to the UE, or the first information indicates a target business related to the UE.

[0109] For another example, if the first information is sent by the UE, the first information may indicate the target service / function. Alternatively, the first information may indicate the target service.

[0110] Furthermore, the first information may also carry an identifier of the UE, so that the first network function can accurately learn the UE and accurately determine the target service of the UE.

[0111] If the first information indicates a target service / function, then, in one embodiment, after receiving the first information, the first network function needs to determine a target service according to the target service / function.

[0112] In actual applications, there may be a pre-set mapping relationship between these target businesses / functions and the target service, and the first network function may quickly and accurately determine the target service based on the mapping relationship.

[0113] The service / function is a service / function performed by the UE through the network. For example, the target service / function includes a UE data transmission service / function, a UE location service / function, or a sensing service / function.

[0114] Then, if the target service / function includes a UE data transmission service / function, the target service determined by the first network function is a service for managing / controlling UE data transmission resource management or a UE data transmission service. If the target service / function includes a UE location service / function, the target service determined by the first network function is a UE location service. If the target service / function includes a perception service / function, the target service determined by the first network function is a perception service.

[0115] In an embodiment of the present application, the first information sent to the first network function may carry various contents that may represent the target service of the UE, so as to clearly indicate the required target service of the UE to the first network function, thereby greatly increasing the accuracy and convenience of the target service of the UE determined by the first network function.

[0116] As can be seen from the previous description, the core network also contains many network functions. For example, the core network includes one or more of the following network functions: session management function, perception function, positioning function, and connection management function. Therefore, in the embodiments of the present application, whenever the core network is mentioned to interact with a first network function or a target second network function, it can be understood that a network function in the core network interacts with the first network function or the target second network function.

[0117] For example, the network function in the core network sends the first information to the first network function.

[0118] For another example, the aforementioned information exchange between the core network and the network functions in the radio access network also refers to information exchange between the network functions in the core network and the network functions in the radio access network. For example, after determining the target second network function, the first network function may cause the network function in the core network to exchange information about the target service with the target second network function.

[0119] However, it should be noted that in some scenarios, a dedicated network function can be set up in the core network to request UE-related services from the radio access network. In such scenarios, there exists a network function in the core network that sends the first information to the first network function, and a network function that ultimately exchanges information for the target service with the target second network function. These network functions may be the same or different network functions.

[0120] The two situations are described below.

[0121] Case 1: The network function in the core network that sends the first information to the first network function and the network function that ultimately interacts with the target second network function for information about the target service are the same network function.

[0122] In one embodiment, the first network function receiving the first information sent by the core network includes: the first network function receiving the first information sent by a third network function in the core network. Based on this, in one embodiment, the method further includes: the first network function sending information of a target second network function providing a target service related to the UE to the third network function.

[0123] In this case, the network function in the core network that sends the first information to the first network function and the network function that ultimately interacts with the target second network function for information of the target service are both third network functions.

[0124] Case 2: The network function in the core network that sends the first information to the first network function and the network function that ultimately interacts with the target second network function for information on the target service are not the same network function.

[0125] In this case, the network function in the core network that sends the first information to the first network function is the fourth network function, but the network function that ultimately interacts with the target second network function for information of the target service is the third network function.

[0126] This is equivalent to the third network function being the one that really needs to be provided with the target service, and the fourth network function only helps the third network function obtain the information of the target second network function from the wireless access network, so that the third network function can be provided with the target service by the target second network function.

[0127] The fourth network function is a network function that helps the third network function obtain information of the target second network function. It can participate in the entire process from sending the first information to obtaining the information of the target second network function, or it can only participate in sending the first information, and let the third network function perform the subsequent process personally.

[0128] The fourth network function only participates in sending the first information, and the third network function performs subsequent processes. In one embodiment, the first network function receiving the first information sent by the core network includes: the first network function receiving the first information sent by the fourth network function in the core network. Based on the first information including information about the third network function, the method further includes: the first network function sending information about a target second network function that provides a target service related to the UE to the third network function.

[0129] That is, when the fourth network function sends the first information to the first network function, it will also attach the information of the third network function. The information of the third network function may be the address or identification information of the third network function, so that the first network function can directly exchange information with the third network function, thereby facilitating the subsequent process of the third network function obtaining the information of the target second network function.

[0130] The fourth network function participates in the entire process from sending the first information to obtaining information about the target second network function. In one embodiment, the first network function receiving the first information sent by the core network includes: the first network function receiving the first information sent by the fourth network function in the core network. The method also includes: the first network function sending information about the target second network function that provides the target service related to the UE to the fourth network function, where the information about the target second network function is used by the fourth network function to send information about the target second network function that provides the target service related to the UE to the third network function in the core network.

[0131] That is, when the fourth network function sends the first information to the first network function, it does not carry the information of the third network function. The first network function cannot directly exchange information with the third network function, and can only communicate back and forth with the fourth network function to deliver the information of the target second network function to the fourth network function. The fourth network function then forwards the obtained information of the target second network function to the third network function, so that the third network function can exchange information with the target second network function.

[0132] The third network function or the fourth network function is a network function in the core network. Therefore, the third network function or the fourth network function can be one or more of the network functions in the core network listed above, that is, the third network function or the fourth network function is one or more of the session management function, the perception function, the positioning function, and the connection management function.

[0133] In an embodiment of the present application, by distinguishing whether the network function in the core network that sends the first information to the first network function and the network function that ultimately interacts with the target second network function for the target service are the same network function, different steps are set respectively, so that the way in which the core network obtains the information of the target second network function is more diversified, enriching the way in which the core network obtains the information of the target second network function, and greatly improving the interaction flexibility between the core network and the wireless access network.

[0134] In the aforementioned embodiment, the purpose of the first network function determining the target second network function is to allow the core network to find the target second network function and exchange information with it. Therefore, after determining the target second network function, the first network function must allow the core network to obtain information about the target second network function.

[0135] In the embodiment of the present application, two possible implementation methods are exemplified for enabling the core network to obtain information about the target second network function:

[0136] Method 1: The first network function is sent directly to the core network.

[0137] Method 2: The target second network function is sent to the core network.

[0138] First, an embodiment of the first approach is described. In one embodiment, the process of directly sending the first network function to the core network includes: the first network function sends second information to the core network; the second information indicates information of a target second network function that provides a target service related to the UE.

[0139] That is, the first network function sends the second information to the core network, and the second information carries the information of the target second network function.

[0140] Taking the third and fourth network functions mentioned in the above embodiments as an example, if the fourth network function does not participate in acquiring information from the target second network function at all, the first network function sending the second information to the core network is equivalent to the first network function sending the second information to the third network function. If the fourth network function only participates in sending the first information, the first network function sending the second information to the core network is equivalent to the first network function sending the second information to the third network function. However, if the fourth network function participates in acquiring information from the target second network function throughout the entire process, the first network function sending the second information to the core network is equivalent to the first network function sending the second information to the fourth network function.

[0141] It should be noted that the second in the second information here is just a distinction between different information, and what I want to emphasize is that the information carrying the target second network function is sent to the third network function or the fourth network function information.

[0142] In an embodiment of the present application, the information of the target second network function is carried in the second information and sent to the core network through the first network function, so that the core network can know which network function can provide the UE-related target service, thereby realizing information interaction between the core network and the target second network function.

[0143] After the first network function determines the target second network function and sends the second information to the core network, the first network function can notify the target second network function by sending an indication message, so that the target second network function is ready to provide the target service. In one embodiment, based on the first network function sending the second information to the core network, the method further includes: the first network function sends fifth information to the target second network function, the fifth information indicating the provision of the UE-related target service and / or the establishment of the UE context. Optionally, the method further includes: the first network function receives sixth information sent by the target second network function, the sixth information being used to respond to the provision of the UE-related target service and / or the establishment of the UE context.

[0144] The context of the UE includes at least one of the following: a UE identifier; an identifier of a network function in a wireless access network for UE data transmission; an address of a network function in a wireless access network for UE data transmission; identifiers of multiple network functions in a wireless access network for UE data transmission; and addresses of multiple network functions in a wireless access network for UE data transmission.

[0145] In the embodiment of the present application, by instructing the target second network function to establish a UE context, the target second network function is informed that a UE-related target service needs to be provided, and preparations for providing the target service are made in advance, thereby ensuring smooth interaction of information between the subsequent core network and the target second network function.

[0146] After the first network function sends the second information to the core network, allowing the core network to learn information about the target second network function, a condition for direct interaction between the core network and the target second network function is met. Based on this, and in addition to the above-mentioned embodiment, in one embodiment, the method includes: the core network sends seventh information to the target second network function, the seventh information requesting a target service related to the UE; the core network receives eighth information sent by the target second network function; the eighth information indicating a response to the target service related to the UE.

[0147] Based on the address or identification information of the target second network function, the core network proactively sends seventh information to the target second network function, requesting that the target second network function provide the target service associated with the UE. After receiving this request, the target second network function replies with eighth information to the core network, indicating that it can provide the target service associated with the UE. In this way, by informing the core network of the information of the target second network function, the core network can quickly and accurately locate the target second network function, enabling direct information exchange with the target second network function for the target service associated with the UE.

[0148] An embodiment of the second method is provided to illustrate. In another embodiment, the method further includes: sending third information to the target second network function; the third information indicates providing a target service related to the UE for the core network and / or establishing a UE context. Optionally, the third information includes core network information, and the core network information is used to indicate to the core network that the target second network function provides the target service related to the UE for the core network.

[0149] In this approach, after the first network function determines the target second network function, it instructs the target second network function to provide the UE-related target service to the core network. Furthermore, the target second network function can also be instructed to establish a UE context, for example, to establish a UE identifier, so that the target second network function can prepare to provide the target service and smoothly provide the UE's target service to the core network.

[0150] At the same time, the first network function may also send core network information to the target second network function. The core network information includes identification information or address information of the core network, for example, identification information or address information of a third network function in the core network, or identification information or address information of a fourth network function in the core network. The first network function sending the core network information may facilitate subsequent processes to be performed directly between the target second network function and the core network, without the first network function being involved. For example, based on the core network information, the target second network function sends fourth information to the core network, where the fourth information instructs the target second network function to provide a target service related to the UE for the core network.

[0151] In an embodiment of the present application, the first network function actively sends the information of the core network to the target second network function, so that the target second network function can send information to the core network based on the identifier or address of the core network, so that the core network can obtain the information of the target second network function, thereby realizing the interaction of UE-related target service information between the core network and the target second network function.

[0202] The above are embodiments that distinguish various information interaction methods provided by different execution entities. The following provides some embodiments of information interaction methods based on the interaction between a first network function, a third network function in the core network, a fourth network function in the core network, and a UE. The implementation principles, processes, and technical effects of each step in the following embodiments are the same as those in the above embodiments and will not be repeated here.

[0203] As shown in FIG5 , based on any of the above embodiments, an embodiment of the present application further provides an information interaction method, which includes the following process:

[0204] S11. A first network function obtains information about at least one second network function and information about at least one UE-related service provided by the at least one second network function. For example, the second network function is a network function in a radio access network for controlling / managing UE data transmission.

[0205] S12. The first network function receives first information from the core network or from the UE, and determines a target service related to the UE based on the first information. For example, the target service is a service for managing / controlling UE data transmission resources.

[0206] S13. The first network function determines a target second network function among at least one second network function, where the target second network function provides a target service related to the UE.

[0207] S14. The first network function sends fifth information to the target second network function, where the fifth information indicates providing a UE-related target service and / or establishing a UE context.

[0208] S15. The target second network function establishes a UE context. The UE context includes, for example, a UE identifier, an identifier of a network function in the radio access network used for UE data transmission, an address of a network function in the radio access network used for UE data transmission, identifiers of multiple network functions in the radio access network used for UE data transmission, and addresses of multiple network functions in the radio access network used for UE data transmission.

[0209] S16. The target second network function sends sixth information to the first network function, where the sixth information is used to respond to providing a UE-related target service and / or establishing a UE context.

[0210] S17. The first network function sends second information to the core network, where the second information indicates information of a target second network function that provides a target service related to the UE; the information is, for example, identification information or address information of the target second network function.

[0211] S18. The core network exchanges information of a target service related to the UE with the target second network function. For example, the information of the target service related to the UE includes at least one of the following: request / response information for establishing / modifying / releasing / deleting UE data transmission resources, and request / response information for establishing / modifying / releasing / deleting UE data transmission channel context.

[0212] In this embodiment, the network function in the core network that sends the first information and the network function that exchanges information about the target service related to the UE with the target second network function may be the same network function or different network functions. The following describes these two situations:

[0213] For the same situation, the core network in S12 (when the first information comes from the core network), S17, and S18 can be replaced by a third network function, for example, a session management function.

[0214] There are two ways for different situations:

[0215] Method 1: The core network in S12 (when the first information comes from the core network) and S17 can be replaced by a fourth network function, and the core network in S18 can be replaced by a third network function. Furthermore, between S17 and S18, the fourth network function sends information about the target second network function that provides the UE-related target service to the third network function, so that after the core network is replaced by the third network function in S18, the third network function and the target second network function exchange information about the UE-related target service.

[0216] Method 2: The core network in S12 (when the first information comes from the core network) can be replaced by the fourth network function, and the core network in S17 and S18 can be replaced by the third network function. In addition, between S12 and S17, the fourth network function also indicates to the first network function that the third network function is requesting the target service related to the UE. This information is, for example, identification information or address information.

[0217] As shown in FIG6 , based on any of the above embodiments, an embodiment of the present application further provides an information interaction method, which includes the following process:

[0218] S21. A first network function obtains information about at least one second network function and information about at least one UE-related service provided by the at least one second network function. For example, the second network function is a network function in a radio access network for controlling / managing UE data transmission.

[0219] S22. The first network function receives first information from the core network or from the UE, and determines a target service related to the UE based on the first information. For example, the target service is a service for managing / controlling UE data transmission resources.

[0220] S23. The first network function determines a target second network function among at least one second network function, where the target second network function provides a target service related to the UE.

[0224] S27. The core network exchanges information of a target service related to the UE with the target second network function. For example, the information of the target service related to the UE includes at least one of the following: request / response information for establishing / modifying / releasing / deleting UE data transmission resources, and request / response information for establishing / modifying / releasing / deleting UE data transmission channel context.

[0225] In this embodiment, the network function in the core network that sends the first information and the network function that exchanges information about the target service related to the UE with the target second network function may be the same network function or different network functions. The following describes these two situations:

[0226] For the same situation, the core network in S22 (when the first information comes from the core network), S24, S26, and S27 can be replaced by a third network function, for example, a session management function.

[0227] There are two ways for different situations:

[0228] Method 1: The core network in S22 (when the first information comes from the core network), S24, and S26 can be replaced by the fourth network function, and the core network in S27 can be replaced by the third network function. Between S26 and S27, the fourth network function also sends information about the target second network function that provides the UE-related target service to the third network function, and the fourth network function can also send the fourth information to the third network function.

[0229] Method 2: The core network in S22 (when the first information comes from the core network) can be replaced by the fourth network function, and the core network in S24, S26, and S27 can be replaced by the third network function.

[0230] As shown in FIG7 , based on any of the above embodiments, an embodiment of the present application further provides an information interaction method, which includes the following process:

[0231] S31. A first network function obtains information about at least one second network function and information about at least one UE-related service provided by the at least one second network function. For example, the second network function is a network function in a radio access network for controlling / managing UE data transmission.

[0232] S32: The first network function receives first information from the core network or from the UE, and determines a target service related to the UE based on the first information. For example, the target service is a service for managing / controlling UE data transmission resources.

[0233] S33. The first network function determines a target second network function among at least one second network function, where the target second network function provides a target service related to the UE.

[0234] S34. The first network function sends second information to the core network, where the second information indicates information of a target second network function that provides a target service related to the UE; the information is, for example, identification information or address information of the target second network function.

[0235] S35. The core network sends seventh information to the target second network function, where the seventh information requests a target service related to the UE.

[0236] S36. The target second network function establishes a context for the UE. The UE context includes, for example, a UE identifier, an identifier of a network function in the radio access network for UE data transmission, an address of a network function in the radio access network for UE data transmission, identifiers of multiple network functions in the radio access network for UE data transmission, and addresses of multiple network functions in the radio access network for UE data transmission.

[0237] S37. The target second network function sends eighth information to the core network, where the eighth information responds to the target service related to the UE;

[0238] S38. The core network exchanges information of a target service related to the UE with the target second network function. For example, the information of the target service related to the UE includes at least one of the following: request / response information for establishing / modifying / releasing / deleting UE data transmission resources, and request / response information for establishing / modifying / releasing / deleting UE data transmission channel context.

[0239] In this embodiment, the network function in the core network that sends the first information and the network function that exchanges information about the target service related to the UE with the target second network function may be the same network function or different network functions. The following describes these two situations:

[0240] For the same situation, the core network in S32 (when the first information comes from the core network), S35, S36, S38, and S39 can be replaced by a third network function, for example, a session management function.

[0241] There are two ways for different situations:

After S38, the fourth network function sends information about the target second network function that provides the UE-related target service to the third network function, and the fourth network function can also send the eighth information to the third network function.

[0243] Method 2: The core network in S32 (when the first information comes from the core network) can be replaced by the fourth network function, and the core network in S35, S36, S38, and S39 can be replaced by the third network function. The fourth network function also indicates to the first network function information about the third network function requesting the UE-related target service.

[0244] It is understandable that the names of the information exchanged between network functions in the various embodiments of the present application are only used to understand the meaning of the information, and other names may also be used. In the various embodiments of the present application, when the sending end and the receiving end of different information are the same, the different information can be sent in the same information or in different information. For example, when the core network sends the first information to the first network function, it can also send the relevant characteristics of the target service at the same time. Alternatively, when the UE sends the first information to the first network function, it can also send the relevant characteristics of the target service at the same time.

[0245] In addition, each step in each embodiment of the present application is not mandatory, and other steps may be included between the steps. The steps in each embodiment of the present application are not limited to being performed in the order described. Some steps in each embodiment of the present application can be performed in parallel. In the present application, two network functions can exchange information through a service-based interface of one or both network functions. Two network functions can also exchange information through a point-to-point interface between the two network functions.

[0246] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
