[0285] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0286] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0287] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0288] This application provides a communication method, apparatus, and storage medium to address the problem of a lack of currently proposed management methods for data service capabilities.

[0289] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0290] The technical solutions provided in this application can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolutionary communication systems, 6G systems, etc. These systems may include terminal equipment and access network equipment. The systems may also include core network equipment, such as Evolved Packet System (EPS), 5G systems (5GS), 6G systems, etc.

[0291] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can be USB storage devices, other personal computer memory devices, and dongles. They can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this application.

[0292] The core network (CN) equipment involved in this application includes user plane function (UPF) network elements, access and mobility management function (AMF) network elements, session management function (SMF) network elements, and policy control function (PCF) network elements. Among these, the UPF network elements are primarily responsible for user data transmission, while the other network elements, which can be referred to as control plane function network elements, are mainly responsible for authentication, authorization, registration management, session management, mobility management, and policy control to ensure reliable and stable transmission of user data.

[0293] The access network equipment involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The access network equipment can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The access network equipment can also coordinate the attribute management of the air interface. For example, the access network equipment involved in this application embodiment can be an evolved access network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., and is not limited in this application embodiment. In some network architectures, access network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0294] In this application embodiment, the terminal device sends relevant information or similar descriptions to the network-side device, which only indicates that the terminal device sends relevant information in the form of wireless signals. The destination recipient is the access network device, which can obtain the relevant information by receiving the wireless signals.

[0295] To better understand this solution, we will first briefly describe the existing technology and its problems, as follows:

[0296] 5G systems provide point-to-point forwarding of user data and network data management functions. Moving towards 6G, communication networks will no longer be just data transmission "channels," but will also need to add a data plane to enable data services such as data collection, transmission, preprocessing, storage, analysis, and consumption.

[0297] The relevant technologies do not cover the process of how different data service nodes report their data service capabilities, nor do they distinguish between different data service nodes, including the service capability characteristics, message flow methods, and service capability updates of different data service nodes.

[0298] To this end, this application proposes a communication method that, unlike other methods that only provide connection services for terminal devices, provides a method for reporting data service capabilities for three types of data service nodes: terminal devices, base station devices, and core network element devices. This method reports the data service capability information of the data service nodes to the first function for management.

[0299] The embodiments of this application are described in detail below. The methods and apparatus are based on the same concept. Since the methods and apparatus solve problems in similar ways, the implementations of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0300] First, the Chinese translations of the English abbreviations appearing in this application are shown in Table 1:

[0302]

[0303]

[0304] Among them, reference Figure 1 The present application provides a flowchart of a communication method applied to a first device, which specifically includes the following steps:

[0305] S101, Send the data service capability information of the first device.

[0306] The first device includes any one of the following: terminal equipment, base station equipment, or core network element equipment. It can be understood that the first device is a device with data service capabilities and the function of reporting data service capability information.

[0307] In one embodiment, the data service capability information includes: data service capability function type parameters of the first device and / or indication information on whether the first device supports the opening of data service capabilities, wherein the function type parameters include: supported data types.

[0308] Specifically, supported data types include AI (Artificial Intelligence) data, sensor data, computing power data, and IoT (Internet of Things) data. The indication information regarding whether the first device supports opening data service capabilities indicates whether the first device supports or does not support opening data service capabilities. If the first device supports opening data service capabilities, its data service capabilities can be used by other devices; if the first device does not support opening data capabilities, its data service capabilities cannot be used by other devices.

[0309] Furthermore, if the data service capability information includes: instruction information from the first device indicating that the data service capability is open, the data service capability information may also include: the scope of the data service capability and / or the opening time.

[0310] It is understood that the scope of data service capability openness is used to indicate the devices that can use the data service capability of the first device, and the open time of data service capability is used to indicate the time during which the data service capability of the first device can be used.

[0311] The first device is a terminal device, and the scope of access includes any of the following: unrestricted use, permitted use, or restricted use. It is understood that if the scope of access includes unrestricted use, any device can use the data service capabilities of the first device. If the scope of access includes permitted use, only permitted devices can use the data service capabilities of the first device. If the scope of access includes restricted use, devices other than those restricted devices can use the data service capabilities of the first device.

[0312] Furthermore, for example, "None" can be used to indicate that there are no restrictions on the scope of use. Permitted devices include: devices within the PLMN (Public Land Mobile Network) that the first device is allowed to subscribe to or access; devices within the current network node that the first device is allowed to access; devices belonging to the same device group as the first device; network devices within the same device group that the first device is allowed to access; devices within a certain distance range from the first device's current location, such as devices belonging to the same TA (Tracking Area) or cell as the first device; devices within the same AF (Application Function) currently accessed by the first device; and other devices within the same AF currently accessed by the first device. Furthermore, the examples of restricted devices are similar to those for permitted devices and will not be repeated here.

[0313] In addition, if no information on the scope of access is provided, the scope of access to the data service capabilities of the first device can be determined based on the UE location, UE subscription data, operator policies, or a certain agreed-upon default policy.

[0314] The data service capability parameters also include at least one of the following: the device type of the first device, an indication of the types of data functions it possesses, and an indication of the current data service status. The device type of the first device, if it is a terminal device, includes, for example, a mobile phone, tablet computer, PDA, laptop computer, mobile internet device (MID), wearable device, VR (Virtual Reality) device, AR (Augmented Reality) device, IoT device, smart agent device, etc. The types of data functions it possesses include, for example, data acquisition function, data storage function, data processing function, etc. The indication of the current data service status indicates whether the first device is currently enabled, inactive, or disabled. If the first device is currently enabled, the indication of the current data service status also carries the intended enabling time period and / or duration.

[0315] S102, receive the data service capability information of the first device as the result of the first function's report.

[0316] The first function is the function of managing the data service capabilities of the first device. The first function can refer to an independent device, a function of network operation management (OAM), a network element in the core network, a function deployed in base station equipment, or a functional module in terminal equipment. There are no limitations on these aspects.

[0317] In the embodiments of this application, the reporting result includes successful reporting or failed reporting. Specifically, when the data service capability information of the first device is successfully reported using the first function, the first function assigns a data node identifier to the first device and sends a successful reporting result to the first device. This reporting result may also carry the data node identifier, which is an identifier indicating that the first device has data service capabilities. When the data service capability information of the first device fails to be reported using the first function, the first function does not assign a data node identifier to the first device and sends a failed reporting result to the first device. The failed reporting result may include a reason for the failure. The reporting result may also be that some data service capability information is successfully reported, while some data service capability information fails to be reported.

[0318] In this embodiment of the application, by sending data service capability information of a first device, wherein the first device includes any one of a terminal device, a base station device, or a core network element device; and receiving the data service capability information of the first device as a reporting result of a first function, wherein the terminal device, the base station device, or the core network element device acts as a data service node, thereby realizing the reporting of data service capabilities of different data service nodes and meeting the requirements of 6G data service scenarios.

[0324] In this embodiment, the core network equipment is used to report data service capability information of various first devices. Alternatively, a terminal device or base station device can act as an intermediate node to forward the data service capability information of the first devices to the core network equipment, thereby achieving the reporting of data service capabilities of different data service nodes and meeting the requirements of 6G data service scenarios.

[0366] Furthermore, when sending data service capability information of a terminal device, the data service capability information can be sent according to the data type, for example, reported to the first function according to data types such as AI data or sensory data.

[0367] It is understandable that the AMF can report the data service capability information of a terminal device to a first function that manages the service area corresponding to that terminal device. The AMF can also report different types of data service capability information of a terminal device to the first function that manages the corresponding service type. Upon receiving the data service capability information of a terminal device, the AMF can immediately or periodically report it to the first function, or it can respond to the data service capability information based on a request from the first function, or it can wait until the data service capability information of multiple terminal devices in the same terminal device group has been obtained before reporting it to the first function. After receiving the data service capability information, the first function can assign a data node identifier to the terminal device.

[0368] S607, Assign data node identifiers.

[0369] The first function is to assign data node identifiers to terminal devices.

[0370] S608, Receive data service capability reporting response message.

[0371] The first function sends a data service capability reporting response message to the AMF, which includes the reporting result of data service capability information.

[0372] S607, Other Registration Processes.

[0373] Other registration processes are not restricted.

[0374] S608, Registration Complete Message.

[0375] The AMF sends a registration completion message to the terminal device. This registration completion message may carry the reporting result of data service capability information. The reporting result includes whether the reporting was successful. The reporting result may also include the area information that allows the terminal device to provide data service capabilities. In addition, the reporting result may also carry the data node identifier.

[0376] In this embodiment of the application, when the AMF receives the data service capability information reported by the terminal device in step S603, it needs to authenticate the identity of the terminal device and determine the authenticity of the data service capability information it provides. The terminal device authentication mechanism can refer to the authentication method of terminal device registration, and is not limited here.

[0377] It is understandable that the data service capability information reported by the terminal device can be confirmed in the following ways after the terminal device's identity authentication is passed: (1) Based on the terminal device's subscription data, determine the data service capability that the terminal device is allowed to provide, or based on the user level and other information of the terminal device's subscription, determine that the terminal device has a high level of trust, and thus consider its data service capability to be trustworthy; (2) Based on the terminal device's subscription data, determine that the data service capability of the terminal device has been initially reported, and then the first function can test or attempt to send relevant data to the terminal device based on the data service capability reported by the terminal device. After the data service capability test of the terminal device is passed, the data service capability information of the terminal device can be maintained in the first function; (3) The first function maintains the terminal device after testing; (4) Based on the above methods, the core network can also maintain the historical status of the terminal device's data service capability, which indicates whether the terminal can correctly complete the data service operation issued by the network, or whether the quality of completion meets the data service capability reported by it. Subsequently, based on the historical service status information, it is determined whether to retain the terminal's data service capability, or select the data service node, or initiate the data service capability registration process triggered by the network.

[0378] In summary, this application enables terminal devices to report their data service capabilities during the initial registration process.

[0385] If the second registration message carries indication information that the first device has data service capabilities, the base station device will preferentially select the AMF that has data service capabilities.

[0387] In this process, the base station equipment forwards the second registration request message to the selected AMF associated with the data service capability information.

[0388] S704, Other Registration Processes.

[0389] Other registration processes are not restricted.

[0390] S705, Send the second registration completion message.

[0391] The second registration completion message indicates that the initial registration of the terminal device is complete.

[0392] S706, Send a third registration request message.

[0393] Among them, terminal devices carry data service capability information in message types such as mobility registration update and periodic registration update, or report data service capability information in registration messages for capability registration update.

[0394] In this application embodiment, mobility registration update occurs in the following two situations: one is N2 handover, and the other is the terminal device configuration update process, that is, when the terminal device needs to update its capabilities or renegotiate protocol parameters. Therefore, data service capability information can be reported in the UE configuration update process in the form of updating capabilities.

[0395] S707, Determine the first function by interacting with the network repository function.

[0396] S708, Select the first function.

[0410] Specifically, refer to Figure 8 ,exist Figure 8 In this context, the first device is either a terminal device or a base station device, and the specific steps include:

[0411] S801, Send a data service request message.

[0412] The core network equipment includes: Access and Mobility Management (AMS). AMS receives data service request messages from the first device. These data service request messages include: indication information for initial registration of data service capabilities and data service capability information.

[0413] It is understandable that the first device initiates a data service-related request message to the core network device. This request message is a data service request message, and the type of the data service request message is capability initial registration, which indicates that the data service request message is related to data service capabilities and is used for the initial registration of data service capabilities.

[0414] Specifically, the first device sends a NAS (Non-Access-Stratum) message to the core network device. This NAS message carries: a data management container for the first function, which includes a data service request message. The data service request message also includes: the type of the first device and / or the first device identifier.

[0427] In this embodiment, terminal devices can report their data service capabilities after initial registration is complete. Base station devices can directly report their data service capabilities.

[0428] exist Figure 8 If the first device is a terminal device, the terminal device first sends the data service capability information to the base station device, which then forwards it to the AMF.

[0429] Among them, Figures 6 to 8 In this context, if the base station equipment is service-oriented, the data service capability information of the terminal equipment can be sent to the base station equipment and then directly sent to the first function without the need for forwarding by the core network equipment.

[0430] Furthermore, in Figures 1 to 8 In this context, the first function can be deployed in terminal equipment, base station equipment, or core network equipment to manage the data service capabilities of the first device.

[0431] Wherein, if the first device is a terminal device or a base station device, Figures 1 to 8 If the first function is deployed on the base station equipment, in one optional embodiment, the terminal equipment or the base station equipment can report data service capability information to the first function of the base station equipment (e.g., RAN DMF), and the first function of the base station equipment manages the data service capabilities of the terminal equipment or the base station equipment and completes the above-mentioned tasks. Figures 1 to 8 The process.

[0432] In another embodiment, if the first device is a terminal device or a base station device, Figures 1 to 8 The first function is deployed in the core network equipment. Terminal equipment or base station equipment can report data service capability information to the first function of the base station equipment (such as RAN DMF) without going through the AMF of the core network equipment. The first function of the base station equipment can directly interact with the first function of the core network equipment (such as CN DMF) through the above process, thereby ensuring that the data service capability of the terminal equipment or base station equipment is reported to the first function of the core network equipment.

[0433] exist Figure 2 Based on, refer to Figure 9 The core network equipment includes: an access and mobility management function that sends data service capability information to the first function, including: the access and mobility management function receiving a subscription request message for data service capability information sent by the first function; and the access and mobility management function sending a notification message for data service capability information to the first function, the notification message including the data service capability information.

[0435] Specifically, refer to Figure 9 Specifically, it includes the following steps:

[0436] S901, interactive access and mobility management functions.

[0437] It is understandable that by interacting with the first function and the network repository function, network element discovery is triggered based on information such as the scope of data service capabilities, thereby discovering AMF.

[0438] S902, Select Access and Mobility Management Functions.

[0439] The first function is to identify the AMFs related to data service capabilities among the multiple AMFs discovered.

[0440] S903, send a subscription request message for the data service capability information of the first device.

[0441] The first function sends a subscription request message for the data service capability information of the first device to the access and mobility management function.

[0442] S904, the process by which a terminal device reports to the access and mobility management function.

[0443] The process of a terminal device reporting to the Access and Mobility Management (AMF) includes: the AMF sending a capability request message to the terminal device; the terminal device sending a capability response message to the AMF based on the capability request message; and the capability response message carrying its own data service capability information.

[0444] In another embodiment, other devices or network elements, such as base station equipment, first function or policy control function, may send a capability request message to the terminal device. The terminal device replies with a capability response message based on the capability request message. These devices or network elements then forward the data service capability information to the AMF.

[0445] In the embodiments of this application, data service capability information can also be reported to AMF in other ways, which are not limited here.

[0446] S905, receive notification messages about data service capability information.

[0447] Among them, the AMF receives notification messages about data service capability information sent by the Access and Mobility Management function.

[0448] In the embodiments of this application, except Figures 6 to 8 In this context, it refers to the terminal device proactively reporting its own data service capabilities information, as shown in the reference section. Figure 9 It can also be a capability request message from a terminal device triggered by base station equipment, the first function, access and mobility management function, or policy control function. Based on this capability request message, the terminal device carries its data service capability information in the response message, and combines it with... Figures 6 to 8 The process ultimately reports data service capability information to the primary function. Furthermore, in Figure 9 The first function sends a subscription request message to the AMF. After the AMF obtains the data service capability information of the terminal device, it notifies the first function.

[0449] In one embodiment, reference is made to Figures 4 to 9 If the terminal device reporting data service capabilities cannot directly access the network, it can forward the data service capability information through a terminal device with relay functionality. For example, in... Figure 6 In this process, the terminal device sends the first registration request message to a terminal device with relay function, which then forwards the first registration request message to the base station device.

[0450] Furthermore, regarding the data service capability information of multiple terminal devices, a terminal device with aggregation capabilities aggregates the data service capability information from multiple devices, and then sends the aggregated data service capability information to the AMF. These multiple terminal devices can form a terminal device group, and the data service capability information within the same terminal device group can be aggregated through a terminal device in that group that has proxy, representative, or gateway functions. For example, in... Figure 6 In this process, multiple terminal devices need to send a first registration request message to the base station device. One of the terminal devices with aggregation function can aggregate the multiple first registration request messages together and then forward them to the base station device.

[0451] In addition, for data service capability information to be reported by multiple terminal devices, the data service capability information can also be aggregated at the network level. For example, the RAN or network elements such as AMF, SEMF, and SMF can aggregate the data service capability information after receiving it from multiple terminal devices.

[0452] In one embodiment, the indication information regarding whether a terminal device possesses data service capabilities can exist in the network as the terminal's subscription data, or it can be provided to the network's OAM through other means when the terminal adds or modifies data service capabilities, and then configured by the OAM into the terminal device's subscription data. The first function interacts with the network element (e.g., UDM) that stores the terminal device's subscription data to obtain a list of terminal devices with data service capabilities.

[0453] Furthermore, regarding information on the data service capabilities of terminal devices, one approach is to obtain it directly from the contracted data; another approach is to first obtain a list of terminal devices with data service capabilities, and then... Figure 9 The data service capability information corresponding to the terminal device is obtained through a network-triggered method.

[0454] In addition to the methods mentioned above, such as OAM configuration or subscription data, users can also manually select the data service capability information to be reported on the terminal device, or configure the data service capability information to be reported in the SIM card of the terminal device.

[0455] In one embodiment, based on Figure 1 , refer to Figure 10 The first device includes: a core network element device. Sending the data service capability information of the first device includes: determining a first function through interaction with the network repository function; sending a data service management establishment request message, which includes: network element information and data service capability information of the core network element device. Receiving the reporting result of the data service capability information of the first device in the first function includes: receiving a data service management establishment response message, which includes: the reporting result of the data service capability information of the first device in the first function.

The method also includes: sending a data service management establishment response message, the data service management establishment response message including: the registration result of the data service capability information in the first function.

[0457] Specifically, refer to Figure 10 This involves core network element devices (CN NFs) directly reporting to the first function. This first function is deployed on the core network device side. Specifically, it includes the following steps:

[0458] S1001, interactive confirmation of the first function.

[0459] Among them, the core network element equipment and the network repository function interact, triggering the network element to send based on the range information of data service capabilities, and the discovery of network element type is the first function.

[0460] S1002, select the first function.

[0461] Among them, the core network element equipment selects the first function.

[0462] S1003, Send a data service management establishment request message.

[0463] Among them, the core network element equipment sends a data service management establishment request message to the first function.

[0464] S1004, Receive data service management establishment response message.

[0465] Among them, the core network element equipment receives the data service management establishment response sent by the first function.

[0466] exist Figure 10 In this context, core network elements are network elements with data capabilities, such as DPFs, or network elements with related functions, such as AMFs, SMFs, or UPFs. If the core network element is a UPF, and the N4 interface between the UPF and SMF is service-enabled, the UPF can directly report data service capability information to the first function. If the N4 interface is not service-enabled, the UPF forwards the data service capability information to the first function through the SMF.

[0467] In conclusion, Figure 10 It provides a process for core network element devices to report data service capabilities to the first function as data service nodes.

[0468] In one embodiment, in Figure 1 Based on, refer to Figure 11 The first device includes: core network element equipment. Sending the data service capability information of the first device includes: sending a first request message. The first request message includes: indication information that the first device has data service capability and data service capability information.

[0469] exist Figure 2 Based on, refer to Figure 11The first device includes: a core network element device, which includes a network repository function. Receiving data service capability information includes: the network repository function receiving a first request message sent by the first device. The first request message includes: indication information indicating that the first device possesses data service capabilities and data service capability information. The first request message is used to request network function service registration or network function service update. Sending data service capability information to the first function includes: the network repository function receiving a subscription message for network element service capabilities sent by the first function; the network repository function sending a notification message for data service capabilities to the first function. The notification message includes: at least one of the following: first device type, first device identifier, and data service capability information.

[0470] exist Figure 3 Based on, refer to Figure 11 The first device is a core network element device, and also includes: sending a subscription message for network data service capabilities to the network repository function; receiving data service capability information includes: receiving a notification message for data service capabilities sent by the network repository function, the notification message including: data service capability information.

[0471] Specifically, refer to Figure 11 The process involves the core network elements first reporting data service capability information to the network repository, and then to the first function. This includes the following steps:

[0472] S1101, Send subscription message for network data service capabilities.

[0473] The network repository function receives request or subscription messages for network data service capabilities from the first function. These messages include: the device identifier of the core network element, and data service parameter information (which can be used to define the scope or range of data service capability information).

[0474] S1102, Send the first request message.

[0475] Specifically, the core network element device sends a first request message to the network repository function. This first request message is used to request network function service registration or network function service update. The first request message includes: a network element configuration file, which includes: an indication of the data service capabilities of the core network element device and the corresponding data service capability information.

[0476] After obtaining new or updated data service capability information based on the aforementioned message, the network repository function determines whether the obtained data service capability information matches the request or subscription of the first function, based on the request or subscription of the first network. If they match, it replies with a response or notification to the first function based on the request or subscription.

[0477] S1103, receive response messages or notification messages from data service capabilities.

[0478] The first function receives response or notification messages from the network repository function. These messages include information about the data service capabilities of the core network element devices. The notification messages also include the device type and / or device identifier of the core network element devices.

[0479] Furthermore, after S1103, the first function can assign data node identifiers to core network element devices, and then forward them to core network element devices through the network repository function.

[0480] S1104, Receive the first response message.

[0481] The network storage function sends a first response message to the core network elements. This first response message may carry the data node identifier.

[0482] The order of S1103 and S1104 is not specified.

[0483] In conclusion, Figure 11 The process provides another core network element device to report data service information to the first function.

[0484] In one embodiment, in Figure 1 Based on, refer to Figure 12 The first device includes: core network element equipment. Sending the data service capability information of the first device includes: sending a second request message, the second request message including: indication information that the first device has data service capability; receiving a request message for data service capability information, the second request message being used to request network function service registration or network function service update; and sending a response message for data service capability information, the response message for data service capability information including: data service capability information.

[0485] exist Figure 2 Based on, refer to Figure 11 and Figure 12 Sending data service capability information to the first function includes: the network repository function receiving a subscription message for network data service capabilities sent by the first function; and the network repository function sending a notification message for data service capabilities to the first function, the notification message including at least one of the following: first device type, first device identifier, and data service capability information.

[0486] exist Figure 3 Based on, refer to Figure 12The first device is a core network element device, and receiving data service capability information includes: sending a subscription message for network data service capability to the network repository function; receiving a notification message for data service capability sent by the network repository function, the notification message including: the first device type and / or the first device identifier; sending a request message for data service capability to the core network element device; and receiving a response message for data service capability, the response message including: data service capability information.

[0487] Specifically, refer to Figure 12 The first piece of equipment is the core network element equipment. Figure 12 The process involves initiating a request over the network, with core network elements responding to report data service capability information. This includes the following steps:

[0488] S1201, Send subscription message for network data service capabilities.

[0489] The network repository function receives subscription messages for network data service capabilities sent by the first function. These subscription messages include: the device identifier of the core network element, and capability updates for core network element devices already providing data services.

[0490] S1202, Send the second request message.

[0491] Specifically, the core network element device sends a second request message to the network repository function. The second request message includes: a network element configuration file, which includes: the data service capabilities of the core network element device.

[0492] S1203, Receive notification message for data service capabilities.

[0493] S1204, Receive the second response message.

[0494] The implementation process of S1201 to S1204 can be referred to as S1101 to S1104, except that the first request message includes data service capability information, while the second request message does not include data service capability information. The first response message includes a data node identifier, while the second response message does not include a data node identifier. In this embodiment, the data node identifier is allocated in S1207.

[0495] In 1204, the core network element only includes indication information or identification of its data service capability in the second request message, but does not carry all data service capability information. In addition, the second request message may optionally carry some data service capability information, such as data service capability type and / or service scope.

[0496] In the embodiments of this application, the execution order of S1203 and S1204 is not limited.

[0497] S1205, Send a request message for data service capabilities.

[0500] Among them, the core network element device sends a response message of data service capability to the first function. The response message carries data service capability information, and the specific content of the data service capability information is determined according to the data service capability template.

[0501] It is understandable that when the first function receives a notification message from the network repository function and determines that a core network element device with data service capabilities has appeared, it requests the specific data service capability information of that core network element device.

[0502] S1207, Assign data node identifiers.

[0503] In this embodiment, the first function assigns a data node identifier to the core network element device. Optionally, when the first function sends a reporting result to the core network element device, it may also send the data node identifier to the core network element device.

[0504] In the embodiments of this application, Figure 12 and Figure 11 The difference is that, in Figure 12 The first function in the system is to subscribe to network elements with data service capabilities only from the network repository function.

[0505] In conclusion, Figure 12 A process is provided for core network element devices to report data service capabilities.

[0506] Furthermore, the data service capabilities of the core network element can be initially configured on the core network element device, or they can be configured on the core network element device through OAM.

[0507] Furthermore, the data service capability information of core network element devices can be reported to the first function through the aforementioned core network element devices, or it can be directly configured in the first function through OAM. Alternatively, it can be configured in other network elements (e.g., a data service capability storage repository) through OAM, and then retrieved by the first function from that network element.

[0508] In one embodiment, the first device is a base station device, as shown in the reference. Figure 8In this process, the NGAP interface between the base station equipment and the core network is enhanced. The data service node type in the data service capability information is the base station equipment. The specific content of the data service capability information of the base station equipment is different from the specific content of the data service capability information of the terminal equipment and the core network element equipment.

[0509] In this embodiment, if the first device is a base station device, and the base station device initiates a data service request message, the data service request message of the first device can be transparently forwarded to the first function through a base station device with relay function. Alternatively, a base station device group can be constructed, in which base station devices with management or gateway functions in the base station device group aggregate data service request messages from other base station devices and then forward them to the first function.

[0510] Furthermore, the base station equipment can directly report data service capability information to the first function on the core network side. In this approach, if the base station equipment is service-oriented, it can directly send data service capability information to the first function.

[0511] In addition, the base station equipment reports data service capability information to the first function on the base station equipment side for management, or the base station equipment reports data service capability information to the first function on the base station equipment side for forwarding the data service capability information to the first function on the core network side for management.

[0512] In one embodiment, the data service capability information of the base station equipment can be initially configured on the base station equipment or configured on the base station equipment through the OAM system. Furthermore, besides being reported by the base station equipment, the data service capability information of the base station equipment can also be directly configured to the first function through OAM. Alternatively, it can be configured to other network elements in the network (e.g., a data service capability storage repository) through OAM, and the first function then retrieves it from that network element.

[0513] In the embodiments of this application, the first function is deployed in one of the terminal device, base station device, or core network.

[0514] exist Figure 3 Based on, refer to Figure 13 Receiving data service capability information includes: sending a request message to the second function to request data service capability information of the first device; and receiving data service capability information sent by the second function.

[0515] Furthermore, multiple DMFs can be divided according to different network domains such as terminal equipment, base station equipment, and core network element equipment, or they can be divided based on different PLMN domains, operators, distributed network node domains, and data service types. DMFs can interact with each other.

[0516] In the case of aggregating the data service capability information of other terminal devices through one terminal device, multiple terminal devices can choose one terminal device to realize the corresponding data service management capability to maintain the data service capability of multiple terminal devices in the corresponding area and interact with the network. The specific interaction content includes: choosing to inform the network of the specific data service capability information of all terminal devices, or informing the network of the data service capability information of some terminal devices based on privacy reasons, or the data service capability information of multiple terminal devices after aggregation.

[0517] The data service capability information exchanged between DMFs includes information about the data service nodes (including the first device type and / or the first device identifier), the data node identifier assigned to it by the DMF, and data service capability information. Regarding the allocation of data node identifiers, different DMFs can have corresponding data node identifier pools, thereby ensuring that data node identifiers are globally unique throughout the entire network.

[0518] Furthermore, referring to Figure 13 This demonstrates a capability for direct data service interaction between DMFs, specifically including the following steps:

[0519] S1301, Send a request message for the data service capability information of the first device.

[0520] The first function is, for example, (DMF 1), and the second function is, for example, (DMF 2). It can be understood that both the first and second functions are functions for managing the data service capabilities of the first device.

[0521] In this embodiment, since the second function manages the data service capabilities of the first device, the first function sends a request message to the second function requesting information about the data service capabilities of the first device. This request message includes information about the first device. Furthermore, the request message may include information about multiple first devices.

[0522] Specifically, the first function sends a request message to the second function to request data service capability information. The request message includes: first device information, which includes at least one of the following: data node identifier, data node identifier list, data function, data service scope, and data service node type.

[0523] S1302, Receive the response message for data service capability.

[0524] The second function sends a response message about data service capabilities to the first function. This response message includes data service capability information and a list of data service nodes.

[0525] Specifically, the second function, based on the request message, obtains the data service capability information corresponding to the data node identifier or identifier list from the second function or the data storage warehouse corresponding to the second function, or the data node identifier or identifier list that conforms to or possesses the data service capability information, and replies to the first function through a response message.

[0526] Furthermore, in addition to Figure 13 Data service capability information can be obtained through request and response patterns, or through subscription and notification patterns.

[0527] In this embodiment of the application, if the first device already has a data node identifier, no data node identifier will be assigned to the first device. After the first function saves the data service capability information, the first device can be notified that the data service capability has been successfully reported in the first function.

[0528] exist Figure 13 In this context, both the first and second functions are deployed on the terminal device side, or both the first and second functions are deployed on the base station device side, or both the first and second functions are deployed on the core network device side.

[0529] In one embodiment, in Figure 3 Based on, refer to Figure 14 Sending a request message for the data service capability information of the first device to the second function includes: sending a request message for the data service capability information of the first device to the second function through the operation and maintenance management function.

[0530] Specifically, for different network domains or the same network domain, the synchronization of corresponding data service capability information can be achieved through OAM. For example, the first function is deployed in the core network, and the second function is deployed in the base station equipment, as shown in the figure. Figure 14 This includes the following steps:

[0531] S1401, Send a request message for the data service capability information of the first device.

[0532] Specifically, the first function sends a request message for data service capability information to the first OAM deployed in the core network. The first OAM forwards the request message to the second OAM deployed in the base station, and the second OAM forwards the request message to the second function.

[0533] S1402, Receive response message for data service capability.

[0534] Specifically, the second function sends a response message of data service capability to the second OAM, the second OAM forwards the response message of data service capability to the first OAM, and the first OAM forwards the response message of data service capability to the first function.

[0535] Among them, Figure 14 For details on the content of request and response messages, please refer to [link / reference]. Figure 13 This will not be elaborated upon here.

[0536] In summary, Figure 14 The first and second functions interact indirectly through OAM. Regarding the interaction between the DMF on the terminal device side and the DMF on the base station device side, and between the DMF on the terminal device side and the DMF on the core network device side, the DMF on the terminal device side can be viewed as a terminal device with management or aggregation capabilities. Figure 14 A similar interaction process.

[0537] In one embodiment, in Figure 3 Based on, refer to Figure 15 Both the first and second functions are deployed in the core network to receive data service capability information, including: receiving data service capability information of the first device sent by the second function through the network repository function. Specifically, this includes the following steps:

[0538] S1501, send a network element discovery request message.

[0539] The first function sends a network element discovery request message to the NRF. Specifically, the first function triggers the network element discovery request message based on information such as the function and scope of the data service capabilities, with the network element type to be discovered being the first function.

[0540] S1502, Receive network element discovery response message.

[0541] The first function receives the network element discovery response message sent by the NRF. This network element discovery response message includes the address information of the second function.

[0542] S1503, Send a request message for data service capability information.

[0543] The first function sends a request message for data service capability information to the second function based on the address information of the second function.

[0544] S1504, Response message for receiving data service capability information.

[0545] The response message for the data service capability information includes: the data service capability information of the first device.

[0546] exist Figure 15 In this system, both the first and second functions are deployed on the core network equipment side. When the first function registers the data service capability information it maintains to the NRF through the NF registration process, the data service capability interaction between the first and second functions can be completed through the NRF's network element discovery process.

[0547] In one embodiment, in Figure 3 Based on, refer to Figure 16 Both the first and second functions are deployed in the core network to receive data service capability information, including receiving data service capability information of the first device sent by the second function through the data repository.

[0548] The data repository can be a UDR, UDSF, or other storage function.

[0549] Specifically, refer to Figure 16 This includes the following steps:

[0550] S1601, Send a storage request message for data service capability information.

[0551] The second function stores data service capability information in UDR, UDSF, or other storage functions.

[0552] S1602, Receive the storage response message for data service capability information.

[0553] S1603, Send a request message for data service capability information.

[0554] The first function can request data service capability information from UDR, UDSF, or other storage functions, and obtain the information through the response.

[0555] S1604, Response message for receiving data service capability information.

[0556] exist Figure 16 In this context, multiple Data Management Files (DMFs) can form a DMF group. DMFs within the same group can share the same data storage repository. Therefore, the data storage repository corresponding to the DMF group can ensure the synchronization of data service capability information among DMFs within the same group. DMFs in different DMF groups can synchronize their data service capability information through the DMF itself or its corresponding data storage repository. Specifically, this includes the following steps:

[0557] In addition, Figure 16 The request and response mode can be used to obtain data service capability information, or the subscription and notification mode can be used to obtain data service capability information, which will not be elaborated here.

[0558] Furthermore, the management of data service capabilities also involves updating data service capabilities and deregistration, etc. The interaction process can be referred to the reporting process described above, and will not be repeated here. In addition, besides updating the service capability status, service capability updates also include changes in the service area or changes in whether the service capability is open, etc.

[0559] In addition, the deregistration of data service capabilities can be triggered by the network judging from the historical service status or situation of the data service node that the data service node is in poor condition or untrustworthy. For the specific deregistration process, please refer to the above-mentioned data service capability reporting process, which will not be repeated here.

[0560] In this embodiment, by distinguishing data service nodes as terminal devices, base station devices, or core network element devices, a corresponding data service capability management process is provided to ensure that data service capabilities can be accurately and cost-effectively maintained in the network, thereby effectively improving data service performance.
