[0114] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0115] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0116] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0117] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0118] The technical background of this application is first described below.

[0119] 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 the 5G system. The NG-RAN contains one or more next-generation base stations (the nextGeneration Node B, gNB). A gNB can be composed of a gNB Central Unit (gNB-CU) and one or more gNB Distributed Units (gNB-DU).

[0120] Among them, gNB-CU carries the radio resource control (RRC), service data adaptation protocol (SDAP) and packet data convergence protocol (PDCP) protocols of gNB. It supports network functions such as UE radio access control, UE connection control, radio bearer control, mobility management, and paging. gNB-DU carries the radio link control (RLC), media access control (MAC) and physical layer of gNB, and some of its operations are controlled by gNB-CU.

[0121] In addition to the 5G wireless access network, the 5G system also includes the 5G core network (also known as 5GC). 5GC includes access and mobility management function (AMF), session management function (SMF), and user plane function (UPF). AMF and SMF can provide services through their service-based interfaces respectively, and AMF and SMF exchange information through service-based interfaces.

[0122] like Figure 1 As shown in the figure, it is a schematic diagram of the overall architecture of NG-RAN. The gNB and 5GC are connected through the logical interface NG interface, and the gNBs are connected through the logical interface Xn-C. Inside the gNB, the gNB-CU and gNB-DU are connected through the protocol interface F1. Among them, the NG interface is divided into the NG-C interface and the NG-U interface. For the user plane, there is an NG-U interface between the gNB-CU and the UPF to transmit UE user plane data. For the control plane, there is an NG-C interface between the gNB-CU and the AMF to transmit signaling. The information exchanged between the gNB-CU and the SMF is transparently forwarded through the NG-C interface and the service-based interface of the AMF.

[0123] In the related technology, only one pair of devices between the core network and RAN can directly exchange information, that is, only the AMF in the core network and the gNB-CU in the RAN interact, and the core network does not interact with the base station logical nodes other than the gNB-CU in the RAN. However, NG-RAN may contain multiple wireless network functions, and different wireless network functions can provide different services related to different UEs for the core network. For example, the introduction of wireless data transmission management network functions in RAN can provide services for controlling / managing UE data transmission in the wireless access network, thereby providing the core network with services for transmitting UE data in the wireless access network.

[0124] However, when multiple wireless network functions are introduced into the RAN, many problems are faced. For example, when the core network needs to interact with a network function in the access network, how should the core network find the network function that provides a certain service in the wireless access network? Therefore, how to perform information interaction between the core network and the network functions in the wireless access network has become a technical problem that needs to be solved urgently. Based on this, the embodiments of the present application provide an information interaction method, device, and processor-readable storage medium that can solve the above problems. Of course, the technical solutions provided in the embodiments of the present application are not limited to solving the above problems, and there are other technical effects. For details, please refer to the following embodiment description.

[0125] Before describing the embodiments of the present application, the application scenarios of the embodiments of the present application are described first.

[0126] The information interaction method provided in the embodiment of the present application can be applicable to, but not limited to, multiple 5G systems, 6G systems, 7G systems, etc. Figure 2 As shown, taking the application scenario of the 5G system as an example, the application scenario includes a wireless access network, a core network and a user equipment (UE). The wireless access network includes multiple wireless network functions (also directly referred to as network functions), which can be divided into a first network function and multiple second network functions ( Figure 2 Only the first network function and the second network function are used as an illustration). The first network function, the second network function, the core network and the UE can communicate with each other in pairs.

[0127] UE includes but is not limited to terminals or network devices, wherein terminals may be but are not limited to various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices, and IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. Network devices may be base stations, wireless access points or other IoT devices, etc.

[0128] The present application provides embodiments with a first network function in a radio access network, a target second network function in a radio access network, a core network and a UE as execution subjects. The embodiment with the first network function in a radio access network as the execution subject is described below.

[0129] In one embodiment, an information interaction method is provided, which is applied to a first network function in a wireless access network, such as Figure 3 As shown, the method may include the following steps:

[0130] S101, determine a target second network function; the target second network function is a network function in a wireless access network used to provide a target service related to a target UE to a core network.

[0131] 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.

[0132] The first network function is any one or more network functions in the wireless access network. For example, an existing network function in the wireless access network may be updated to become the first network function, or a new network function may be added to the wireless access network as the first network function.

[0133] The other network functions in the wireless 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 target UE.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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 wireless access network, or to manage UE data transmission between the wireless access network and the core network.

[0138] 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.

[0139] Optionally, the 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 sensing provides a service for sensing. The function for positioning provides a service for UE location.

[0140] In an embodiment of the present application, the first network function in the wireless access network is used to determine the target second network function in the wireless access network that provides the target service related to the target UE to the 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. Service-related information. Therefore, the target second network function refers to a network function that can provide a target service related to the target UE. Because the target second network function is any one or more network functions in the wireless 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 wireless access network, in one embodiment, the target service related to the target UE 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.

[0141] For example, when the target service is a service for managing / controlling UE data transmission resources, it indicates that 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, it indicates that the target second network function can be the network function responsible for the perception function.

[0142] 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 target UE, or by detecting a request from the core network for information interaction. The embodiment of the present application is not limited to this.

[0143] 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 that can provide a target service related to the target UE from the wireless access network. 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.

[0144] In the embodiment 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. Figure 4 As shown, 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:

[0145] S201, obtaining information of at least one second network function in a radio access network and information indicating UE-related services provided by the second network function.

[0146] 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 wireless access network, as well as information about UE-related services that can be provided by these second network functions.

[0147] 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.

[0148] 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.

[0149] The information used to indicate the UE-related services provided can be understood as indicating which UE-related services the second network function can provide. For example, the information used to indicate the UE-related services provided can be an identifier of the UE-related service and / or a type identifier of the UE-related service.

[0150] In addition, in the 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 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, and multiple second network functions providing multiple UE-related services.

[0151] Therefore, in the embodiment of the present application, the determined target second network function includes but is not limited to a network function. For example, when the target service related to the target UE is 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 target UE is provided by one second network function, the target second network function may be only the one second network function.

[0152] S202: Determine a target second network function according to information about a UE-related service provided by at least one second network function.

[0153] In the above steps, after the first network function obtains the information of at least one second network function in the wireless access network and the information indicating the UE-related services provided by it, it is equivalent to that the first network function already knows in advance the UE-related services that each second network function can provide. Then the first network function can determine the target second network function from multiple second network functions based on this information.

[0154] 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 wireless data transmission management network function in a wireless access network, the second network function is used to provide services for controlling / managing UE data transmission in the wireless access network, so that the second network function can provide services for transmitting UE data in the wireless access network to the core network, or the second network function can provide services for controlling / managing UE data transmission in the wireless access network to the core network.

[0155] It should be noted that, in the embodiment of the present application, the process in which the first network function obtains the information of the second network function and the information indicating the UE-related service provided by it, and the process in which the first network function determines the target second network function according to the information of the UE-related service provided by the second network function can be two independently implemented processes. It is not limited to perform the S202 process after performing the S201 process.

[0156] 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 identifier or type identifier 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.

[0157] Based on the above embodiments, in one embodiment, the process of determining the target second network function by the first network function according to the information of the UE-related service provided by at least one second network function includes: determining a network function that can provide the target service related to the target UE among the at least one second network function as the target second network function.

[0158] Based on the information about UE-related services provided by at least one second network function, the first network function can know in advance the UE-related services that can be provided by at least one second network function in the wireless access network. Therefore, the first network function can directly, quickly and accurately screen out the target second network function that can provide the target service related to the target UE from the at least one second network function, thereby improving the efficiency and accuracy of determining the target second network function.

[0159] 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 network function among the at least one second network function that can provide the target service related to the target UE and meets the preset conditions as the target second network function.

[0160] Although the main purpose of the first network function determining the target second network function is to provide the target service to the core network, in some scenarios, in order to enable the determined target second network function to smoothly and comprehensively provide the target service to the core network. Therefore, 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 target service related to the target UE, 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.

[0161] The following is a description of the content that meets this preset condition.

[0162] In one embodiment, meeting the preset condition includes the load satisfying at least one of the preset load condition and the relevant characteristics that can satisfy the target service.

[0163] That is, 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 target service related to the target UE and whose load satisfies a preset load condition.

[0164] 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 target service related to the target UE and can meet relevant characteristics of the target service.

[0165] 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 target service related to the target UE, whose load satisfies a preset load condition, and which can meet relevant characteristics of the target service.

[0166] 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.

[0167] For example, the load condition may be a load threshold, and meeting 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.

[0168] In addition, in some cases, the target second network function can provide the target service related to the target 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 requirements of the service when providing the target service.

[0169] 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.

[0170] 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 target 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.

[0171] In combination with the previous embodiments, it can be known that the target service can be any UE-related service, for example, a service for managing / controlling UE data transmission resources, a service for UE data transmission, a service for UE location, a perception service, etc.

[0172] 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.

[0173] 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.

[0174] In yet another embodiment, when the target service is a perceived service, the relevant characteristics of the target service include perceived service quality information.

[0175] For example, taking the slice information to which the relevant feature is the UE data, 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.

[0176] For another example, the relevant feature is the quality information of UE data transmission, which means that when providing the target service this time, a required transmission quality can be achieved for UE data transmission. Then the target service that can be provided by the target second network function must be able to meet the transmission quality.

[0177] Therefore, whether it is the slice information to which the UE data belongs, 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.

[0178] 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 while providing the target service, as well as the load condition 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.

[0179] Since the target second network function represents a network function that can provide a target service related to the target UE, the first network function needs to determine the target service related to the target UE before determining the target second network function.

[0180] The following describes a process in which the first network function determines a target service related to the target UE.

[0181] In one embodiment, before determining the target second network function, the method further includes: receiving first information sent by the core network or the target UE, and determining a target service related to the target UE according to the first information.

[0182] In the embodiment of the present application, the functional entity that sends the first information may be different, that is, the first information may be sent by the core network to the first network function, or may be sent by the target UE to the first network function. After receiving the first information, the first network function may determine the target service related to the target UE according to the first information. In this way, the first network function determines the target service by sending the first information to the first network function through the core network or the target UE, so that the first network function can quickly learn the target service related to the target UE.

[0183] Optionally, the first information indicates a target service related to the target UE; or, the first information indicates a target service of the target UE; or, the first information indicates a target function of the target UE. Optionally, the first information includes at least one of the following: an identifier of the target service; an identifier of a type of the target service; an identifier of a target service; an identifier of a type of the target service; an identifier of a target function; an identifier of a type of the target function; an identifier of the target UE.

[0184] Whether it is the core network or the target 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.

[0185] For example, the first information is sent by the core network, and the first information may indicate a target service related to the target UE, or the first information indicates a target business related to the target UE.

[0186] For another example, if the first information is sent by the target UE, the first information may indicate the target business / function. Alternatively, the first information indicates the target service.

[0187] Furthermore, the first information may also carry an identifier of the target UE, so that the first network function can accurately obtain the target UE and accurately determine the target service of the target UE.

[0188] 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.

[0189] In actual applications, there may be a pre-set mapping relationship between these target businesses / functions and the target services, and the first network function may quickly and accurately determine the target service based on the mapping relationship.

[0190] 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 perception service / function.

[0191] Then, for the target service / function including the 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 service for UE data transmission. For the target service / function including the UE location service / function, the target service determined by the first network function is a service for UE location. For the target service / function including the perception service / function, the target service determined by the first network function is a perception service.

[0192] 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 target UE, so as to clearly indicate the required target service of the target UE to the first network function, thereby greatly increasing the accuracy and convenience of the target service of the target UE determined by the first network function.

[0193] Combined with the previous description, it can be seen that there are many network functions in the core network. 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 interacts with the first network function or the target second network function, it can be understood that a certain network function in the core network interacts with the first network function or the target second network function.

[0194] For example, the network function in the core network sends the first information to the first network function.

[0195] For another example, the core network mentioned in the foregoing content and the network functions in the wireless access network perform information interaction, which also refers to the network functions in the core network and the network functions in the wireless access network performing information interaction. For example, after determining the target second network function, the first network function can enable the network function in the core network to perform information interaction of the target service with the target second network function.

[0196] However, it should be noted that in some scenarios, a network function can be specially set up in the core network to request UE-related services from the wireless access network. In this scenario, there is a network function in the core network that sends the first information to the first network function, and a network function that finally interacts with the target second network function for the target service. They may be the same network function or different network functions.

[0197] These two situations are described below.

[0198] 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 of the target service are the same network function.

[0199] 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 third network function in the core network. On this basis, in one embodiment, the method also includes: the first network function sending information of the target second network function that provides the target service related to the target UE to the third network function.

[0200] 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.

[0201] 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 of the target service are not the same network function.

[0202] 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.

[0203] This means that it is the third network function that really needs to be provided with the target service, and the fourth network function only helps the third network function to 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.

[0204] The fourth network function is a network function that helps the third network function obtain the 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.

[0205] The fourth network function only participates in sending the first information, and the subsequent process is performed by the third network function. In one embodiment, the first network function receives the first information sent by the core network, including: the first network function receives the first information sent by the fourth network function in the core network. On the basis that the first information includes information of the third network function, the method also includes: the first network function sends information of the target second network function that provides the target service related to the target UE to the third network function.

[0206] 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.

[0207] The fourth network function participates in the entire process from sending the first information to obtaining the information of 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 sends information of the target second network function that provides the target service related to the target UE to the fourth network function, and the information of the target second network function is used by the fourth network function to send information of the target second network function that provides the target service related to the target UE to the third network function in the core network.

[0208] 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 send 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.

[0209] The third network function or the fourth network function are both network functions 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.

[0210] 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, the way in which the core network obtains the information of the target second network function is enriched, and the interaction flexibility between the core network and the wireless access network is greatly improved.

[0211] In the above embodiment, it is mentioned that 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 the first network determines the target second network function, it is necessary to allow the core network to obtain the information of the target second network function.

[0212] In the embodiment of the present application, two possible implementation methods are exemplified for allowing the core network to obtain the information of the target second network function:

[0213] Method 1: The first network function is sent directly to the core network.

[0214] Method 2: The target second network function is sent to the core network.

[0215] First, an embodiment is provided to illustrate the first approach. 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 target UE.

[0216] 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.

[0217] Taking the third network function and the fourth network function mentioned in the above embodiment as an example, when the fourth network function does not participate in the information acquisition of the target second network function at all, the first network function sending the second information to the core network is the first network function sending the second information to the third network function. When the fourth network function only participates in sending the first information, the first network function sending the second information to the core network is still the first network function sending the second information to the third network function. However, when the fourth network function participates in the information acquisition of the target second network function throughout the process, the first network function sending the second information to the core network is the first network function sending the second information to the fourth network function.

[0218] 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.

[0219] 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 target service related to the target UE, thereby realizing information interaction between the core network and the target second network function.

[0220] When the first network function determines the target second network function and sends the second information to the core network, the first network function can inform 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 also includes: the first network function sends fifth information to the target second network function, and the fifth information indicates providing the target service related to the target UE and / or establishing the context of the target UE. Optionally, the method also includes: the first network function receives the sixth information sent by the target second network function, and the sixth information is used to respond to providing the target service related to the target UE and / or establishing the context of the target UE.

[0221] Among them, the target UE context includes at least one of the following: UE identification; an identification of a network function in the wireless access network for UE data transmission; an address of a network function in the wireless access network for UE data transmission; identifications of multiple network functions in the wireless access network for UE data transmission; addresses of multiple network functions in the wireless access network for UE data transmission.

[0222] In the embodiment of the present application, by instructing the target second network function to establish a target UE context, the target second network function is informed that a target service related to the target UE 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.

[0223] After the first network function sends the second information to the core network so that the core network learns the information of the target second network function, the condition for direct interaction between the core network and the target second network function is met. Based on this, on the basis of the above embodiment, in one embodiment, the method includes: the core network sends seventh information to the target second network function, the seventh information requests the target service related to the target UE; the core network receives the eighth information sent by the target second network function; the eighth information indicates the target service related to the target UE to be responded.

[0224] The core network actively sends the seventh information to the target second network function according to the address or identification information of the target second network function, so as to request the target second network function to provide the target service related to the target UE to itself. After receiving this request, the target second network function replies with the eighth information to the core network, indicating that it can respond to the target service related to the target 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 find the target second network function, and realize the information interaction of the target service related to the target UE directly with the target second network function.

[0225] An embodiment of the above-mentioned method 2 is provided for explanation. In another embodiment, the method further includes: sending third information to the target second network function; the third information indicates providing the target service related to the target UE for the core network and / or establishing the context of the target UE. Optionally, the third information includes information of the core network, and the information of the core network is used by the target second network function to indicate to the core network that it provides the target service related to the target UE for the core network.

[0226] In this manner, after the first network function determines the target second network function, it will instruct the target second network function to provide the target service related to the target UE to the core network. Further, the target second network function can also be instructed to establish a context of the target UE, for example, to establish a UE identifier, so that the target second network function can prepare for improving the target service and smoothly provide the target service of the target UE to the core network.

[0227] At the same time, the first network function may also send core network information to the target second network function, where 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 may send core network information to facilitate subsequent processes to be directly performed between the target second network function and the core network, without the first network function being involved. For example, the target second network function sends fourth information to the core network based on the core network information, where the fourth information indicates that the target second network function provides target services related to the target UE to the core network.

[0228] 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 as to facilitate the core network to obtain the information of the target second network function, thereby realizing the exchange of information of the target service related to the target UE between the core network and the target second network function.

[0229] The above is based on the perspective that the execution subject is the first network function, and the embodiments involved in the information interaction method provided in the embodiment of the present application are described. Based on the same technical concept, the embodiment of the present application also provides an embodiment related to the information interaction method with the core network as the execution subject, wherein the principles, methods and technical effects involved in the implementation process of each step in the embodiment with the core network as the execution subject are the same as those in the previous embodiment, and the parts and beneficial effects that are the same as those in the previous method embodiment will not be specifically repeated here.

[0230] The following are embodiments of the information interaction method with the core network as the execution entity.

The following describes the two situations as follows:

[0303] 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, the third network function is a session management function.

[0304] There are two ways for different situations:

[0308] S31. The first network function obtains information of at least one second network function and information indicating at least one UE-related service provided by the first network function. For example, the second network function is a network function in a wireless access network for controlling / managing UE data transmission.

[0316] In this embodiment, the network function in the core network that sends the first information and the network function that interacts with the information of the target service related to the target UE with the target second network function may be the same network function or different network functions. The following two cases are described:

[0317] For the same case, in S32 (when the first information is from the core network), S35, S36, S38, and S39, the core network can be replaced by a third network function. For example, the third network function is a session management function.

[0318] For different cases, there are two methods:

[0321] 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 may 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, the relevant features of the target service may be sent together. Alternatively, when the target UE sends the first information to the first network function, the relevant features of the target service may also be sent together.

[0322] 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 be performed in the described order. 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.

[0323] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed 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 part of the steps or stages in other steps.
