For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

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

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

[0288] This disclosure provides communication methods, apparatus, and storage media 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 disclosure 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 disclosure 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 may 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) telephones, 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 disclosure.

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

[0295] To better understand this disclosure, the relevant technologies and problems of the relevant technologies are briefly described below:

[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 merely data transmission "channels," but will also need to add data plane / data framework / data functions / data-related functions to realize 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 disclosure proposes a communication method that, unlike other methods that only provide connection services for terminal devices, provides a method for reporting / registering data / 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 (including data parameters / information, such as data types) of the data service nodes to the first function for management.

[0299] The embodiments of this disclosure 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 details will not be repeated.

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

[0301] Table 1

[0302] Referring to FIG1, a flowchart of a communication method provided in this disclosure is applied to a first device and includes the following steps:

[0303] S101, Send the data service capability information of the first device.

[0304] 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, possessing the function of reporting / registering / reporting data service capability information.

[0305] 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.

[0306] It should be noted that data service capability information can also be data information, such as data-related information that the first device can generate or collect (including data from other nodes, other entities, and other devices).

[0307] Supported data types include AI (Artificial Intelligence) data, sensory data / perceptual 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. 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.

[0308] It is understood that the communication method provided in this disclosure is applicable not only to the reporting / registration and management of data service capabilities, but also to other capabilities, such as computing power, AI capabilities, or sensing capabilities.

[0309] In some embodiments, if the data service capability information includes: indication information of the first device indicating that the data service capability is open, the data service capability information may further 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 device / entity / region 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 can be understood that if the scope includes unrestricted use, any device can use the data service capabilities of the first device. If the scope includes permitted use, only the permitted device / device list / device located within the permitted area can use the data service capabilities of the first device. If the scope includes restricted use / device list / devices within a restricted area, other devices besides the restricted devices can use the data service capabilities of the first device.

[0312] In some embodiments, for example, "None" can be used to indicate that there is no restriction on the scope of use. Permitted devices include, for example, devices within a 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 currently accessing the same AF as the first device. Furthermore, the examples of restricted devices refer 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. This 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 is no limitation in this regard. When the first function is a network function / network element in the core network, it can be an existing network function of the 5G system, an enhancement or change of an existing network function, or a network function newly introduced in 6G.

[0317] In the embodiments of this disclosure, 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 disclosure, 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.

[0323] In this embodiment of the disclosure, the core network device acts as an intermediate node, used to send the data service capability information uploaded by the first device to the first function.

[0324] In this embodiment, the core network device 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 device, thereby achieving the reporting of data service capabilities of different data service nodes and meeting the requirements of 6G data service scenarios. Referring to Figure 3, this disclosure also provides a flowchart of a communication method applied to a first function, including the following steps:

[0328] S302, assign a data node identifier to the first device.

[0329] The first function, upon receiving data service capability information, can assign a data node identifier to the first device and / or store the device identifier (such as UE identifier, network function identifier) ​​and the mapping relationship between the device identifier and the data service capability information. The data storage entity can be the first function itself, or other data warehouses or data storage functions. It is understood that in some cases, it is not necessary to assign a data node identifier to the first device; only the original device identifier and its data service capability information need to be maintained. Furthermore, the first function sends the reporting results of the data service capability information.

[0330] In this embodiment of the disclosure, the first function can receive reports of data service capability information from various first devices, thereby enabling the management of data service capabilities of different data service nodes and meeting the requirements of 6G data service scenarios.

[0331] In one embodiment, referring to FIG4, which is a schematic diagram of direct interaction between the first device and the first function, the following steps are followed:

[0341] In S504, one approach is for the first function to directly send the data service capability information reporting result of the first function to the first device. Another approach is for the first function to send the data service capability information reporting result of the first function to the core network device. The core network device then sends the data service capability information reporting result of the first function to the first device.

[0342] In this embodiment of the disclosure, the first function can interact with the core network equipment and the first device to report the data service capability information of various first devices, thereby enabling the first function to manage the data service capabilities of different data service nodes and meet the requirements of 6G data service scenarios.

[0343] In one embodiment, based on FIG1 and referring to FIG6, the first device includes: a terminal device, and sending the data service capability information of the first device includes: sending a first registration request message, the first registration request message including: a first registration type, indication information that the first device has data service capability and data service capability information, the first registration type being initial registration.

[0347] S601, Send the first registration request message.

[0348] It is understood that in this step, the terminal device sends a first registration request message to the base station device, which includes data service capability information.

[0349] The first registration request message also includes: a first device identifier, which contains indications that the first device has data service capabilities.

[0350] It is understood that, in one embodiment, the first registration request message includes: indication information that the first device has data service capabilities and a first device identifier.

[0355] Upon receiving the first registration request message, the base station equipment can prioritize selecting an AMF (Active Data Function) related to data service capability information based on the AN (Answer Parameter). If the base station equipment cannot select an AMF related to data service capability information, it can select an AMF unrelated to data service capability information, and then use that unrelated AMF to select the AMF related to data service capability information.

[0356] S603, Send the first registration request message.

[0357] The base station equipment forwards the first registration request message to the selected AMF (Application Function) associated with the data service capability information.

[0358] S604. Determine the first function by interacting with the network repository function.

[0359] Among them, AMF discovers the first function that matches the type and scope of data service capabilities with the data service capability information of the terminal device through the network element discovery process with the Network Repository Function (NRF).

[0360] In the embodiments disclosed herein, the first function may be a DMF (Data Management Function), or other devices / entities that manage data service capabilities, such as a 5G DCCF or similar data collection coordination function or sensing function SF, which are not limited herein.

[0361] S605, Select the first function.

[0362] In this embodiment of the disclosure, the AMF selects one first function from a plurality of first functions discovered in step S604, wherein the selection of the first function is based on the data service type, the data service capability range, and the load status of each first function. The selected first function is capable of managing the data service capabilities of the terminal device.

[0363] S606, Send a data service capability reporting request message.

[0364] Among them, AMF sends a data service capability reporting request message to the first function, which includes: data service capability information of one or more terminal devices.

[0365] In this embodiment of the disclosure, the AMF can send the data service capability information of one terminal device to the first function at a time, or it can send the data service capability information of multiple terminal devices to the first function at a time. The multiple terminal devices can be a group of terminal devices.

[0366] In some embodiments, 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 disclosure, 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 disclosure enables terminal devices to report their data service capabilities during the initial registration process.

[0379] In one embodiment, based on FIG1 and referring to FIG7, the first device includes: a terminal device, and sending the data service capability information of the first device includes: sending a second registration request message, the second registration request message including: a first registration type and indication information that the first device has data service capability, the first registration type being initial registration; receiving a second registration completion message; and sending a third registration request message, the third registration request message including: a second registration type and data service capability information, the second registration type including at least one of the following: mobility registration update, periodic registration update, or capability registration update.

[0380] Based on Figure 2 and referring to Figure 7, the first device includes a terminal device, and the core network device includes an access and mobility management function (AM / M) function. Before receiving data service capability information, the AM / M receives a second registration request message sent by the terminal device through the base station device. The second registration request message includes a first registration type and indication information indicating that the first device has data service capability. The first registration type is initial registration. The AM / M sends a second registration completion message. Receiving data service capability information includes the AM / M receiving a third registration request message. The third registration request message includes a second registration type and data service capability information. The second registration type includes mobility registration update, periodic registration update, or capability registration update.

[0381] Referring to Figure 7, the first device is a terminal device with data service capabilities. The terminal device reports its data service capabilities during mobility registration update, periodic registration update, or capability registration update after the initial registration is completed. This includes the following steps:

[0382] S701, Send the second registration request message.

[0383] It is understood that in this step, the terminal device sends a second registration request message to the base station device. This second registration request message may carry indication information that the first device has data service capabilities, but does not include data service capability information.

[0384] S702, Select Access and Mobility Management Functions.

[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.

[0386] S703, Send the second registration request message.

[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 embodiment of the disclosure, mobility registration update occurs in 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.

[0397] S709, Send a data service capability reporting request message.

[0398] The data service capability reporting request message includes: data service capability information of one or more terminal devices.

[0399] S710, Assign data node identifiers.

[0400] S711, Receive data service capability reporting response message.

[0401] The implementation process of S707 to S711 is the same as that of S604 to S608, and will not be repeated here.

[0402] S712, Other registration and update processes.

[0403] However, no restrictions are imposed on other registration and update processes.

[0404] S713, Registration Complete Message.

[0405] The implementation process of S712 is the same as that of S609, and will not be described in detail here.

[0406] In summary, this disclosure enables terminal devices to report data service capabilities during mobility registration updates, periodic registration updates, or capability registration updates after the initial registration process.

[0407] In one embodiment, based on FIG1 and referring to FIG8, the first device includes: a terminal device or a base station device. Sending the data service capability information of the first device includes: sending a data service request message. The data service request message includes: indication information for initial registration of data service capabilities and data service capability information. The data service request message also includes: the first device type and / or the first device identifier.

[0408] In one embodiment, based on Figure 2 and referring to Figure 8, the first device includes: a terminal device or a base station device, and the core network device includes: an access and mobility management function (AMAC) receiving data service capability information, including: the AMAC receiving a data service request message sent by the first device, the data service request message including: indication information for initial registration of data service capabilities and data service capability information. Sending data service capability information to a first function includes: the AMAC determining the first function through interaction with the network repository function; the AMAC sending a data service management establishment request message to the first function, the data service management request message including: device information and data service capability information of the first device. It also includes: the AMAC receiving a data service management establishment response message, the data service management establishment response message including: the reporting result of the first device's data service capability information in the first function; the AMAC sending a data service response message to the first device, the data service response message including: the reporting result of the first device's data service capability information in the first function.

[0409] In one embodiment, based on FIG3 and referring to FIG8, the first device includes a terminal device or a base station device, and receives data service capability information, including: receiving a data service management establishment request message sent by the access and mobility management function, the data service management request message including: device information and data service capability information of the first device; the method further includes: sending a data service management establishment response to the access and mobility management function.

[0410] Referring to Figure 8, where the first device is a terminal device or a base station device, the process includes the following steps:

[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.

[0415] S802, Determine the first function by interacting with the network repository function.

[0416] The access and mobility management function determines the primary function by interacting with the network repository function.

[0417] S803, Select the first function.

[0418] The implementation process of S802 and S803 is the same as that of S604 and S605, and will not be repeated here.

[0419] S804, Send a data service management establishment request message.

[0420] The Access and Mobility Management function sends a Data Service Management Establishment Request message to the First Function.

[0421] It is understood that the Data Service Management Establishment Request message is used by the AMF to request the first function to establish a context for the data service capability of the first device, and the Data Service Management Establishment Request message includes data service capability information.

[0422] S805, Assign data node identifiers.

[0423] S806, Receive data service management establishment response message.

[0424] The Access and Mobility Management function receives a Data Service Management Establishment Response Message, which includes: the data service capability information of the first device and the reporting result of the first function.

[0425] S807, Send data service response message.

[0426] The Access and Mobility Management function sends a data service response message to the first device. The data service response message includes: the data service capability information of the first device and the reporting result of the first function.

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

[0428] In 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] In Figures 6 to 8, 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 by the base station equipment, without the need for forwarding by the core network equipment.

[0430] In some embodiments, as shown in Figures 1 to 8, the first function may be deployed in a terminal device, base station device, or core network device to manage the data service capabilities of the first device.

[0431] If the first device is a terminal device or a base station device, and the first function in Figures 1 to 8 is deployed on the base station device, then in one embodiment, the terminal device or the base station device can report data service capability information to the first function of the base station device (e.g., RAN DMF), and the first function of the base station device manages the data service capability of the terminal device or the base station device and completes the process described in Figures 1 to 8.

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

[0433] Based on Figure 2 and referring to Figure 9, the core network equipment includes: an access and mobility management function that sends data service capability information to a 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.

[0434] Based on Figure 3 and referring to Figure 9, the first device includes a terminal device that receives data service capability information, including: sending a subscription request message for the data service capability information of the first device to the access and mobility management function; and receiving a notification message for the data service capability information sent by the access and mobility management function, the notification message including the data service capability information.

[0435] Referring to Figure 9, the steps include:

[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 this embodiment of the disclosure, data service capability information may 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 this embodiment of the disclosure, besides Figures 6 to 8 showing the terminal device actively reporting its own data service capability information, as shown in Figure 9, the terminal device can also receive a capability request message triggered by a base station device, a first function, an access and mobility management function, or a policy control function. Based on this capability request message, the terminal device carries its data service capability information in a response message, and ultimately reports the data service capability information to the first function in conjunction with the processes shown in Figures 6 to 8. Furthermore, in Figure 9, the first function first sends a subscription request message to the AMF, and the AMF, after receiving the terminal device's data service capability information, notifies the first function.

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

[0450] In some embodiments, for data service capability information of multiple terminal devices, a terminal device with aggregation function aggregates the multiple data service capability information, and then sends the aggregated data service capability information to the AMF. These multiple terminal devices can form a terminal device group, and data service capability information within the same terminal device group can be aggregated by a terminal device in that group that has proxy, representative, or gateway functions. For example, in Figure 6, if 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 these 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 the terminal can inform the network's OAM through other means when adding or modifying data service capabilities, with the OAM configuring it into the terminal device's subscription data. The first function interacts with the network element (e.g., UDM) that stores the terminal devices' subscription data to obtain a list of terminal devices with data service capabilities.

[0453] In some embodiments, regarding the data service capability information of a terminal device, one approach is to obtain it directly from the contracted data, and another approach is to obtain the data service capability information corresponding to the terminal device through the network-triggered method shown in Figure 9 after obtaining the list of terminal devices with data service capabilities.

[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 FIG1 and referring to FIG10, 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.

[0456] Based on Figure 3 and referring to Figure 10, the first device is a core network element device. Receiving data service capability information includes: receiving a data service management establishment request message sent by the core network element device. The data service management establishment request message includes: network element information and data service capability information of the core network element device. The method further includes: sending a data service management establishment response message. The data service management establishment response message includes: the registration result of the data service capability information in the first function.

[0457] Referring to Figure 10, the core network element (CN NF) directly reports to the first function. This first function is deployed on the core network equipment side and 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] In Figure 10, the core network element device is a network element with data function, such as a DPF, or it can be a network element with related functions, such as an AMF, SMF, or UPF. If the core network element device is a UPF, and the N4 interface between the UPF and SMF is service-enabled, then 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 summary, Figure 10 provides the process by which core network element devices, acting as data service nodes, report their data service capabilities to the first function.

[0468] In one embodiment, based on FIG1 and referring to FIG11, the first device includes: a core network element device, and sending the data service capability information of the first device includes: sending a first request message, the first request message including: indication information that the first device has data service capability and data service capability information.

[0469] Based on Figure 2 and referring to Figure 11, the first device includes: a core network element device, which includes: a network repository function, receiving data service capability information, including: the network repository function receiving a first request message sent by the first device, the first request message including: indication information that the first device has data service capabilities and data service capability information, the first request message being 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 including: first device type, first device identifier, and data service capability information, at least one of these.

[0470] Based on Figure 3 and referring 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] Referring to Figure 11, the core network element device first reports data service capability information to the network repository function, and then to the first function, including 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] In some embodiments, after S1103, the first function can assign a data node identifier to the core network element device and then forward it to the core network element device 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 summary, Figure 11 provides another process for core network element devices to report data service capability information to the first function.

[0484] In one embodiment, based on FIG1 and referring to FIG12, the first device includes: a core network element device. 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] Based on Figure 2, and referring to Figures 11 and 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; 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] Based on Figure 3 and referring to Figure 12, the first device is a core network element device. 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] Referring to Figure 12, the first device is a core network element device. Figure 12 illustrates the reporting of data service capability information through a network-initiated request and a response from the core network element device, including 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 also carries some data service capability information, such as data service capability type and / or service scope.

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

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

[0498] The first function involves sending a data service capability request message to the core network elements. This request message may carry a data service capability template.

[0499] S1206, Receive response message for data service capability.

[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, the content of which 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 core network element device to obtain its data service capability information.

[0502] S1207, Assign data node identifiers.

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

[0504] In this embodiment of the disclosure, the difference between Figure 12 and Figure 11 is that in Figure 12, the first function only subscribes to network elements with data service capabilities from the network repository function.

[0505] In summary, Figure 12 provides a process for core network element devices to report data service capabilities.

[0506] In some embodiments, the data service capability information of the core network element may be initially configured in the core network element device, or it may be configured in 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. Referring to FIG8, the base station device and the core network perform NGAP interface enhancement. The data service node type in the data service capability information is the base station device. The content of the data service capability information of the base station device is different from the content of the data service capability information of the terminal device and the core network element device.

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

[0510] In some embodiments, 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-enabled, it can directly send the 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 this embodiment of the disclosure, the first function is deployed in one of the terminal device, base station device, or core network.

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

[0515] In some embodiments, multiple DMFs can be divided according to different network domains such as terminal equipment, base station equipment, and core network element equipment. Alternatively, multiple DMFs can be divided based on different PLMN domains, operators, distributed network node domains, data service types, etc., and the 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 content of the interaction includes: choosing to inform the network of the 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] In some embodiments, referring to FIG13, a direct data service capability information exchange between DMFs is illustrated, 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 of the disclosure, since the second function has managed 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] 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] 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 meets or possesses the data service capability information, and replies to the first function through a response message.

[0526] In some embodiments, in addition to obtaining data service capability information through the request and response mode of Figure 13, data service capability information can also be obtained through the subscription and notification mode.

[0527] In this embodiment of the disclosure, 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] In Figure 13, the first function and the second function are both deployed on the terminal device side, or both the first function and the second function are deployed on the base station device side, or both the first function and the second function are deployed on the core network device side.

[0529] In one embodiment, based on FIG3 and referring to FIG14, 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] 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. Referring to Figure 14, the steps include:

[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] In Figure 14, the content of the request message and response message is shown in Figure 13, and will not be repeated here.

[0536] In summary, in Figure 14, the first and second functions interact indirectly through OAM. For the interaction between the DMF on the terminal device side and the DMF on the base station device side, as well as 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 regarded as a terminal device with management or aggregation capabilities, using an interaction process similar to that in Figure 14.

[0537] In one embodiment, based on Figure 3 and referring 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. 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. The first function triggers the network element discovery request message based on information such as the function and scope of data service capabilities, and the network element type to be discovered is 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] In Figure 15, 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, based on Figure 3 and referring to Figure 16, both the first function and the second function 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 a data repository.

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

[0549] Referring to Figure 16, the steps include:

[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] In Figure 16, multiple DMFs can form a DMF group. DMFs within the same group can share the same data storage warehouse. Therefore, the data storage warehouse 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 warehouse. This includes the following steps:

[0557] In addition to the request and response mode shown in Figure 16, data service capability information can also be obtained through the subscription and notification mode, which will not be elaborated here.

[0558] In some embodiments, the management of data service capabilities also involves updating data service capabilities and deregistering, etc. The interaction process can refer 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. The deregistration process can refer to the above-mentioned data service capability reporting process, and will not be repeated here.

[0560] In this embodiment of the disclosure, 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.
