[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.
[0038] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure.
[0039] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0041] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0043] Figure 1 It is a flowchart of a communication method according to some embodiments of the present disclosure.
[0044] In some embodiments, Figure 1 The method shown may be executed by a service management function (SMF).
[0045] like Figure 1 As shown, in step S110, a Non-Access Stratum (NAS) message is received from an Access and Mobility Management Function (AMF). Here, the NAS message carries a first data service capability registration request initiated by a User Equipment (UE), and the first data service capability registration request carries the data service capability information of the UE.
[0046] NAS messages may also be referred to as NAS signaling, and may be used, for example, for authentication, registration, and connection / session management between UE and core network in mobile communications. AMF may include, for example, an enhanced access and mobility management function (eAMF). UE may include, for example, a terminal device with wireless communication functions that supports user access to network services. Data service capability information refers to information related to data service capabilities, and the content of data service capability information will be further described later.
[0047] In step S120, the first data service capability registration request is parsed to obtain data service capability information.
[0048] In step S130, a second data service capability registration request carrying data service capability information is sent to an enhanced NF Repository Function (eNRF) to register the data service capability information with the eNRF. The eNRF may be enhanced by, for example, a network service storage function (NF Repository Function, NRF) in a 5G network architecture.
[0049] In some embodiments, in step S130, a service-based interface (SBI) message is sent to the eNRF, and the SBI message carries the second data service capability registration request. That is, the second data service capability registration request is sent by sending the SBI message.
[0050] After registering the data service capability information of the UE, the eNRF may return a first data service capability registration response to the SMF.
[0051] In step S140, in response to the first data service capability registration response from the eNRF, a second data service capability registration response is sent to the UE via the AMF.
[0052] It should be understood that the first data service capability registration response and the second data service capability registration response can both indicate that the data service capability information of the UE has been registered with the eNRF.
[0053] In the above embodiment, SMF can parse the NAS message to obtain the data service capability information of the UE, and send the second data service capability registration request carrying the data service capability information of the UE to the eNRF, so that the UE can register the data service capabilities it supports to the core network, which provides a basis for the core network to uniformly manage and schedule the data service capabilities of the UE, so that the mobile communication network can provide data service services.
[0054] The data service provided by the mobile communication network may include, for example, the 6G synaesthesia service. In the 6G synaesthesia service, the network side can select appropriate nodes to send and receive perception signals according to the perception service request of the demand side (for example, including information such as regional location and accuracy) and the data service capability information reported by the UE (such as service area and perception accuracy), and perform perception measurements and generate perception results. Based on the above embodiments, unified management and scheduling of the data service capabilities of the UE can be achieved, thereby supporting end-to-end unified data collection, global data transmission, processing, storage and sharing, so that data can be conveniently, efficiently and securely provided to network internal functions or network external functions for use, thereby supporting mobile communication networks such as 6G networks to achieve data service capabilities that exceed human-to-human communication.
[0055] In some embodiments, the data service capability information includes one or more of a data service capability registration indication (Data ServiceCapability Registration Indicator), data service capability registration contents (Data ServiceCapability Registration Contents), a data service capability registration content field length (Length of DataService Capability Registration Contents), and a data service message type (DataServiceMessage Type).
[0056] Here, the data service capability registration indication is used to identify that the NAS message carries the first data service capability registration request. For example, the presence of the data service capability registration indication indicates that the NAS message carries the data service capability registration request; the absence of the data service capability registration indication indicates that the NAS message does not carry the data service capability registration request. In some embodiments, the SMF can determine whether the NAS message carries the first data service capability registration request based on whether the data service capability registration indication exists in the NAS message.
[0057] As shown in Table 1, the data service capability registration content may include, for example, one or more of a data service providing entity identifier, a data service providing entity type identifier, a data service capability type, a data service capability region, a data service capability quality, and a data transmission protocol type.
[0058] Table 1 Data service capability registration content
[0059] The data service capability registration content field length is used to indicate the length of the data service capability registration content so that the SMF can completely read the data service capability registration content of this length.
[0060] In some embodiments, the data service capability information carried in the first data service capability registration request received from the AMF is in a compressed state, and the data service capability information carried in the second data service capability registration request sent to the eNRF is in a decompressed state. In this case, after receiving the first data service capability registration request, the SMF parses the first data service capability registration request to obtain the data service capability information in a compressed state; then, the data service capability information in a compressed state can be decompressed to obtain the data service capability information in a decompressed state.
[0061] In the above embodiment, on the one hand, the NAS message carries compressed data service capability information, and can send as much data service capability information as possible under the premise of meeting the capacity limit of the NAS message. On the other hand, the SMF decompresses the data service capability information when parsing the NAS message (for example, the SBI message carries the decompressed data service capability information), so that the eNRF does not need to decompress the data service capability information after receiving the second data service capability registration request, thereby reducing the processing burden of the eNRF and improving the registration efficiency of the eNRF.
[0062] For example, when the eNRF processes the data service capability registration of multiple UEs at the same time, the SMF decompresses the data service capability information when parsing the NAS message, which helps to reduce the processing burden of the eNRF and improve the eNRF registration efficiency.
[0063] Figure 2 is a signaling diagram of a communication method according to some embodiments of the present disclosure.
[0064] like Figure 2 As shown, in step S210, the UE sends a NAS message to the eAMF, and the NAS message carries a first data service capability registration request. The first data service capability registration request carries the data service capability information of the UE. The data service capability information can refer to the relevant introduction in the previous text.
[0065] In step S220, the eAMF sends a first data service capability registration request to the SMF.
[0066] In step S230, the SMF parses the first data service capability registration request to obtain data service capability information of the UE.
[0067] In step S240, the SMF sends an SBI message to the eNRF, where the SBI message carries a second data service capability registration request.
[0068] In step S250, the eNRF stores the UE data service capability registration information.
[0069] In step S260, the eNRF sends an SBI message to the SMF, where the SBI message carries a first data service capability registration response. The first data service capability registration response is used to confirm the completion of the data service registration.
[0070] In step S270, the SMF sends a NAS message to the AMF, where the NAS message carries a second data service capability registration response.
[0071] In step S280, the AMF returns a second data service capability registration response to the UE.
[0072] Two different NAS messages and corresponding data service capability registration processes are introduced below in conjunction with some embodiments.
[0073] In some embodiments, the SMF is a connection service management function (CSMF), and the NAS message is a PDU session establishment request. In some embodiments, the connection service management function is also called a link service management function.
[0074] Here, CSMF can be improved from the session management function (SessionManagementFunction) in the 5G network architecture. Compared with the session management function in the 5G network, CSMF adds the ability to parse the first data service capability registration request and send the second data service capability registration request to the eNRF.
[0075] It should be understood that the PDU session process is an existing process in the 5G network. In the above embodiment, the existing PDU session process is fully utilized, and there is no need to change the existing NAS message protocol framework. It is only necessary to add data service capability information to the existing PDU session establishment request and make a small change to the network elements on the core network side to achieve the registration of data service capabilities. The above embodiment has very little change to the existing network, reducing the cost of implementing data service services on the existing network architecture, and is particularly suitable for the transition plan from 5G to 6G.
[0076] In some embodiments, the NAS message is a PDU session establishment request, and the second data service capability registration response is a PDU session establishment response. In this way, both the data service capability registration request and the data service capability registration response can be implemented using the existing PDU session process, further reducing the cost of implementing data service services on the existing network architecture.
[0077] In some embodiments, the Protocol Configuration Option (PCO) field of the PDU session establishment request carries a first data service capability registration request. The PCO field is a PCO additional parameters list. The PCO field can be used to provide the UE with additional information for connecting to the network. The PCO field in some embodiments of the present disclosure is used to implement the UE's data service capability registration.
[0078] Figure 3 is a schematic diagram of a PCO field according to some embodiments of the present disclosure.
[0079] like Figure 3As shown, a single PCO field in the NAS message of the PDU session includes an independent container identifier (ContainerID), a container content length indication (Length of container ID contents), and a container content (ContainerID contents). For example, the container identifier occupies 2 bytes, the container content length indication occupies 1 byte, and the container content is up to 255 bytes. The range of container ID 0xFF00H~0xFFFFH is reserved for the operator's own use. A container ID (for example, 0xFF00H) is selected from the range to indicate the first UE data service capability registration request, and the container content length indication is used to indicate the length of the data service capability registration content, while the container content carries the complete data service capability registration content. In addition, considering the limitation of the field length, the data service capability registration content can be encoded and compressed.
[0080] In the above embodiment, considering that the PCO field is a field that has been defined in the 5G standard and is used to carry additional UE messages (such as DNS server address requirements, etc.), there is also an unused container ID. Therefore, a PCO field can be selected for UE data service capability registration. In this way, the PCO field in the existing process is used to carry the first data service capability registration request without changing the NAS message structure and process, further reducing the changes to the existing network process and further reducing the cost of implementing data service business on the existing network architecture.
[0081] In some embodiments, the PCO field of the PDU session establishment response carries the first data service capability registration response. That is, the second data service capability registration response includes the first data service capability registration response. In this way, the PCO field in the existing process is used to carry the first data service capability registration response, further reducing the changes to the existing network process and further reducing the cost of implementing data service business on the existing network architecture.
[0082] Figure 4 is a signaling diagram of a communication method according to some embodiments of the present disclosure.
[0083] Combine the following Figure 4 This section describes the signaling flow when the SMF is the CSMF and the NAS message is a PDU session establishment request.
[0084] In step 1, the UE writes the data service capabilities it supports into the PCO field in the PDU session establishment request. Specifically, the data service capability registration indication, data service capability registration content field length, and data service capability registration content are added to the PCO Additional parameters list of the NAS message of the PDU session. The data service capability registration indication, data service capability registration content field length, and data service capability registration content can refer to the previous introduction.
[0085] In step 2, the UE initiates an uplink NAS message transmission to the AMF. The NAS message is used to establish a PDU session and carries a first data service capability registration request.
[0086] In step 3, the AMF identifies that the uplink NAS message is a PDU session establishment request carrying the first data service capability registration request.
[0087] In step 4, the AMF transparently transmits the NAS message to the selected CSMF.
[0088] In step 5, the CSMF parses the PDU session establishment request and extracts the data service capability information of the UE from the PCO field. In some embodiments, the CSMF also performs a conventional PDU session establishment process, which will not be described in detail in this disclosure.
[0089] In step 6, the CSMF initiates a second data service capability registration request to the eNRF through a newly added SBI message, where the second data service capability registration request includes the UE data service capability information parsed from the PCO field.
[0090] In step 7, the eNRF stores the data service capability information of the UE.
[0091] In step 8, the eNRF returns a first data service capability registration response to the CSMF.
[0092] In step 9, the CSMF writes the first data service registration response into the PCO field of the second data service capability response (ie, the PDU session establishment response).
[0093] In step 10, the CSMF initiates downlink NAS message transmission to the UE and returns a PDU session establishment response.
[0094] It should be understood that steps 4 to 9 of the above process only include the processing steps of UE data service capability reporting, and the description of the conventional 5G PDU session establishment steps is omitted.
[0095] In some other embodiments, SMF is a data service capability management function (Data Service Management Function, DSMF), and the NAS message is a NAS message dedicated to data services, which may also be called a new NAS message or a data service NAS message.
[0096] In the above embodiment, a NAS message dedicated to data services is added, and SMF is a DSMF used to manage data service capabilities. In this way, the UE's data service capability registration process can be initiated independently without being bound to the PDU session management, which is more flexible and more in line with the future 6G data service architecture.
[0097] In some embodiments, after parsing the first data service capability registration request and obtaining the data service capability information, the SMF (eg, DSMF) further stores the data service capability information.
[0098] In the above embodiment, the DSMF stores the data service capability information, so that the DSMF can subsequently perform arrangement according to the data service capability information of the UE stored in the DSMF.
[0099] Figure 5 is a signaling diagram of a communication method according to some embodiments of the present disclosure.
[0100] Combine the following Figure 5 The data service capability registration process is described in the case where the SMF is the DSMF and the NAS message is a NAS message dedicated to data services.
[0101] In step 1, the UE writes the data service capabilities supported by the UE into a NAS message dedicated to data services, that is, a newly added NAS message or a data service NAS message.
[0102] Specifically, the NAS message dedicated to data service is a NAS message dedicated to data service that is newly added on the basis of the existing NAS message and is parallel to mobility management and session management. The specific fields of the NAS message dedicated to data service may include data service message type and data service capability registration content. The data service message type is used to indicate the purpose of the NAS message, for example, indicating that the NAS message is used for data service capability registration. The data service capability registration content can refer to the relevant introduction in the previous text.
[0103] In step 2, the UE initiates an uplink NAS message transmission to the AMF (e.g., eAMF), where the NAS message carries a first data service capability registration request.
[0104] In step 3, the eAMF identifies that the NAS message carries the first data service capability registration request, that is, it is identified as a data service NAS message.
[0105] In step 4, the eAMF transparently transmits the NAS message carrying the first data service capability registration request to the DSMF.
[0106] In step 5, the DSMF parses the NAS message, extracts the data service capability information, and caches the data service capability information (including but not limited to the data service capability registration content in the data service capability information) locally to facilitate subsequent operations related to the data service capability business.
[0107] In step 6, the DSMF initiates a second data service capability registration request to the eNRF through a newly added SBI message based on the parsed data service capability information of the UE.
[0108] In step 7, the eNRF stores the data service capability information of the UE so as to be used by other DSMFs to discover and arrange data services of the UE.
[0109] In step 8, the eNRF returns a first data service capability registration response to the DSMF to confirm the completion of the data service registration.
[0110] In step 9, the DSMF initiates a downlink NAS message transmission to the UE, and the downlink NAS message carries a second data service capability registration response.
[0111] In the above embodiment, the NAS message protocol framework is modified, and additional processes are added to add support for data services. The network elements involved in the modification include eNRF, eAMF and the newly added DSMF. eNRF is used to register data service capabilities and store data service capability information. eAMF is used to identify NAS messages for data services and transparently transmit them to DSMF.
[0112] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the method executed by the UE, the method executed by the AMF, the embodiment, the SMF, the UE, the AMF and the system embodiment, since they basically correspond to the method embodiment executed by the SMF, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
[0113] Figure 6 It is a flowchart of a communication method according to some embodiments of the present disclosure. Figure 6 The method shown may be performed by a UE.
[0114] In step S610, a NAS message carrying a first data service capability registration request is sent to SMF via AMF, and the first data service capability registration request carries the data service capability information of the UE, so that SMF sends a second data service capability registration request carrying the data service capability information to eNRF to register the data service capability information with eNRF.
[0115] In step S620, a second data service capability registration response sent by the SMF in response to the first data service capability registration response from the eNRF is received via the AMF.
[0116] Figure 7 It is a flowchart of a communication method according to some embodiments of the present disclosure. Figure 7 The method shown may be performed by an AMF.
[0117] In step S710, a NAS message is received from a UE. Here, the NAS message carries a first data service capability registration request, and the first data service capability registration request carries data service capability information of the UE.
[0118] In step S720, a NAS message is sent to the SMF, so that the SMF sends a second data service capability registration request carrying the data service capability information to the eNRF, so as to register the data service capability information with the eNRF.
[0119] At step S730, a second data service capability registration response sent by the SMF in response to the first data service capability registration response from the eNRF is received.
[0120] In step S740, a second data service capability registration response is sent to the UE.
[0121] In some embodiments, the NAS message is a PDU session establishment request, or a NAS message dedicated to data services; the SMF is a connection service management function CSMF, or a data service capability management function DSMF.
