Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] The integration or fusion of communication and perception is a hot topic in current communication technology. From the perspective of technological development, it is also a gradual process, and there is a lot of content that needs to be studied internally. Synaesthesia fusion can effectively improve the quality of communication and realize contactless perception. It is a relatively promising development scenario in the future. It needs to be studied in all aspects from the perspectives of architecture, key technologies and evaluation indicators. The application scenarios of 5G technology have gradually become clear. Relying on the network to expand business is the future network's focus and balance point for development. However, based on the current 5G communication architecture, it is not possible to support perception functions, and thus it is impossible to realize the deployment of measurement perception capabilities in the local network.

[0065] The present invention discloses a network architecture and implementation of a synaesthesia fusion method for optimizing a fifth-generation communication system, which can be applied to application scenarios of synaesthesia fusion based on 5G communication technology, and includes a Converged Multi-sensing Management Function (CMSMF) entity for performing perception message collection and calculation in a communication system, and a control plane and a data plane for perception message transmission.

[0066] Figure 1 It is one of the flow charts of the method for transmitting the perception message provided by the present invention. The execution subject is the fusion multi-sensor management function CMSMF. The method for transmitting the perception message of the present invention includes:

[0069] Sending the perception result to the access and mobility management function AMF, and instructing the access and mobility management function AMF to send the perception result to the application function AF;

[0070] The perception request is determined based on the application function AF generating and sending it to the access and mobility management function AMF;

[0071] The sensing result is determined by calculation based on the measured sensing signal;

[0072] The perception message includes the perception request, the perception instruction, the perception signal and the perception result.

[0073] In step 101, the present invention adds a new network element entity in the 5G network architecture, the fusion multi-sensor management function CMSMF, and the fusion multi-sensor management function CMSMF extends the local management function (Location Management Function, LMF) to provide fusion perception message management and fusion functions, including positioning, personnel intrusion detection, vital signs detection, gesture / posture recognition and other perception capabilities.

[0074] Optionally, a perception request sent from an access and mobility management function (AMF) is received, and the perception request is parsed to determine a target user equipment (UE) and / or a target radio access network (NG-RAN), wherein the target radio access network is a 5G radio access network in the present invention, and the perception request is generated according to the application function (AF), and the application function AF sends the perception request to the access and mobility management function AMF, and the access and mobility management function AMF forwards the perception request to the converged multi-sensing management function CMSMF, wherein the perception request includes at least perception indication information of the target user equipment UE and / or the target radio access network NG-RAN. The access and mobility management function AMF can send subscription request information of the perception task to the converged multi-sensing management function CMSMF, and can forward perception signaling and perception measurement information between the target user equipment UE and / or the target radio access network NG-RAN and the converged multi-sensing management function.

[0075] In step 102, a perception instruction is sent to the target user equipment UE and / or the target radio access network NG-RAN to instruct the target user equipment UE and / or the target radio access network NG-RAN to send and / or obtain a measurement perception signal, wherein the perception instruction is used to instruct the target user equipment UE and / or the target radio access network NG-RAN to send and / or receive a measurement perception signal, wherein the measurement perception signal may be channel state information (Channel State Information, CSI). In an optional embodiment, after the target user equipment UE and / or the target radio access network NG-RAN receives the perception instruction, the target user equipment UE and / or the target radio access network NG-RAN starts to perform a detection operation and uploads the measurement perception signal to the converged multi-sensing management function CMSMF in real time, and the multi-sensing management function CMSMF is used to analyze the measurement perception signal.

[0076] In another optional embodiment, when a preset reporting condition is met, a measurement perception signal is sent to a converged multi-sensing management function CMSMF, and the converged multi-sensing management function CMSMF further obtains the measurement perception signal fed back from the target user equipment UE and / or the target radio access network NG-RAN.

[0077] In step 103, the perception result is sent to the access and mobility management function AMF, and the access and mobility management function AMF is instructed to send the perception result to the application function AF, the perception result is determined based on the measured perception signal, and optionally, the fusion multi-sensor management function CMSMF is inferred based on the reported measured perception signal and the local minimum mean square error model, and calculates the perception result. The access and mobility management function AMF is responsible for the identity authentication, authorization, registration, mobility management and connection management of the target user equipment, and the application function AF is similar to an application server, which interacts with other 5G core network control planes and provides business services.

[0078] The application function AF may exist for different application services. In the present invention, the application function AF sends the perception request to the access and mobility management function AMF, and the access and mobility management function AMF forwards the perception request to the converged multi-sensing management function CMSMF. The converged multi-sensing management function CMSMF receives the perception request sent from the access and mobility management function AMF, parses the perception request to determine the target user equipment UE and / or target wireless access network NG-RAN for measuring perception, and then sends a perception instruction to the target user equipment UE and / or target wireless access network NG-RAN to instruct the target user equipment UE and / or target wireless access network NG-RAN to send and / or obtain a measurement perception signal, and finally sends the perception result to the access and mobility management function AMF, and sends the perception result to the application function AF based on the access and mobility management function AMF to complete the synaesthesia fusion process based on the 5G network.

[0079] Optionally, the sending of the perception instruction to the target user equipment UE and / or the target radio access network NG-RAN includes: sending the perception instruction to the target user equipment UE and / or the target radio access network NG-RAN through the access and mobility management function AMF, such as Figure 7 As shown, Figure 7 This is the third flow chart of the method for transmitting the perception message provided by the present invention. As the basic implementation of the synaesthesia fusion method in the 5G network, it mainly utilizes the access and mobility management function AMF to realize the transmission of the perception message in the synaesthesia fusion. Specifically:

[0080] The target user equipment UE and / or the target wireless access network NG-RAN reports the perception capability information, the application function AF directly or through the network element function (Network Element Function, NEF) requests the access and mobility management function AMF to obtain the perception message of a certain area or some target user equipment UE and / or the target wireless access network NG-RAN, and the access and mobility management function AMF forwards the perception request to the converged multi-sensing management function CMSMF; the converged multi-sensing management function CMSMF determines the information of the target user equipment UE and / or the target wireless access network NG-RAN that needs to be perceived according to the perception request, and triggers the perception request to the target user equipment UE and / or the target wireless access network NG-RAN; the converged multi-sensing management function CMSMF sends a perception request to the target user through the access and mobility management function AMF The device UE and / or the target wireless access network NG-RAN sends a perception instruction; the target user equipment UE and / or the target wireless access network NG-RAN detects that the measurement perception signal meets the reporting condition, triggering a perception reporting message; the target user equipment UE and / or the target wireless access network NG-RAN transmits the measurement information to the fused multi-sensor management function CMSMF through the access and mobility management function AMF; the fused multi-sensor management function CMSMF obtains a perception result based on the reported measurement perception information and the local ML model reasoning calculation; the fused multi-sensor management function CMSMF sends the perception result to the application function AF through the access and mobility management function AMF.

[0081] The present invention provides a method and device for transmitting a perception message, which increases a network element entity integrating a multi-sensing management function CMSMF, receives a perception request sent from an access and mobility management function AMF, parses the perception request, sends a perception instruction to a target user equipment UE and / or a target wireless access network NG-RAN, obtains a measurement perception signal, sends a perception result to the access and mobility management function AMF, and instructs the access and mobility management function AMF to send the perception result to an application function AF, thereby realizing a network architecture with inter-sensing in a 5G system, meeting the deployment of measurement perception capabilities in a local network after network functions are sunk in an edge computing environment, reducing the transmission delay and signaling overhead of measurement information, and improving the response time of measurement perception.

[0082] Figure 2 It is one of the flow diagrams of sending a perception instruction provided by the present invention, wherein the sending of the perception instruction to the target user equipment UE and / or the target radio access network NG-RAN includes:

[0083] Sending identification information of a converged multi-sensing management function CMSMF to the target user equipment UE and / or the target radio access network NG-RAN;

[0084] receiving identification feedback information from the target user equipment UE and / or the target radio access network NG-RAN, so as to establish a first session channel with the target user equipment UE and / or the target radio access network NG-RAN according to a user plane function (User Plane Function, UPF);

[0085] A measurement perception signal of the target user equipment UE is received through the first session channel.

[0086] In step 1021, identification information of the fused multi-sensor management function CMSMF is sent to the target user equipment UE, where the target user equipment UE is a device for receiving measurement perception signals. The fused multi-sensor management function CMSMF determines the target user equipment UE for which perception needs to be initiated according to the perception request, and sends identification information of the fused multi-sensor management function CMSMF to the target user equipment UE, where the identification information is used to establish a protocol data unit (PDU) session between the user plane function UPF and the target user equipment UE and the fused multi-sensor management function CMSMF.

[0087] In step 1022, the target user equipment UE receives the identification information, generates identification feedback information based on the identification information, and sends the identification feedback information to the fused multi-sensing management function CMSMF. The fused multi-sensing management function CMSMF receives the identification feedback information from the target user equipment UE to establish a first session channel between the target user equipment UE and the fused multi-sensing management function CMSMF through the user plane function UPF.

[0088] In step 1023, the measurement perception signal of the target user equipment UE is received through the first session channel. In such an embodiment, compared with Figure 7 The technical solution of using access and mobility management function AMF to realize the transmission of perception messages in synaesthesia fusion is provided. Figure 2 The illustrated embodiment introduces a user plane function UPF, implements the construction of the first session channel and the transmission of the perception message, and can implement the interactive transmission of the perception message without going through the access and mobility management function AMF. Figure 7 The access and mobility management function AMF described in the above is a higher-level entity in the network element and is far away from the locally deployed base station. If the access and mobility management function AMF is used as the medium for the perception message transmission, the forwarding path will be longer, resulting in a transmission delay of the measurement information and increasing the response time of the measurement perception. Figure 2The forwarding of the access and mobility management function AMF is bypassed, and the use of the access and mobility management function AMF to realize the transmission of perception messages is effectively avoided, thereby reducing the transmission delay of the measurement information and the response time of the measurement perception.

[0089] Figure 3 This is a second flow chart of sending a perception instruction provided by the present invention, wherein the sending of the perception instruction to the target user equipment UE and / or the target radio access network NG-RAN includes:

[0090] Sending a connection establishment request to the target radio access network NG-RAN according to the transmission interface;

[0091] receiving connection establishment feedback information from the target user equipment UE and / or the target radio access network NG-RAN to establish a second session channel with the target user equipment UE and / or the target radio access network NG-RAN;

[0092] receiving a measurement perception signal of a target radio access network NG-RAN through the second session channel;

[0093] The transmission interface is used for sensing the transmission of messages.

[0094] In step 1024, the transmission interface is used for the transmission of the perception message, and the reference point between the converged multi-sensing management function CMSMF and the target wireless access network is used as the transmission of the air interface wireless perception message during the control plane optimized transmission. That is, in such an embodiment, the information interaction between the converged multi-sensing management function CMSMF and the target user equipment UE and / or the target wireless access network NG-RAN is realized according to the transmission interface, and then a connection establishment request is sent to the target wireless access network NG-RAN according to the transmission interface.

[0095] In step 1025, connection establishment feedback information from the target wireless access network NG-RAN is received to establish a second session channel with the target wireless access network NG-RAN. The converged multi-sensing management function sends a connection establishment request to the target wireless access network NG-RAN. The target wireless access network NG-RAN receives the connection establishment request and generates connection feedback information with a confirmation indication, and sends it to the converged multi-sensing management function CMSMF. The converged multi-sensing management function CMSMF receives the connection establishment feedback information from the target wireless access network NG-RAN, and then establishes a second session channel with the target wireless access network NG-RAN.

[0096] In step 1026, a measurement perception signal of the target radio access network NG-RAN is received through the second session channel. In such an embodiment, compared with Figure 7The technical solution of using access and mobility management function AMF to realize the transmission of perception messages in synaesthesia fusion is provided. Figure 3 The embodiment shown introduces a transmission interface, realizes the construction of the second session channel and the transmission of the perception message, and can realize the interactive transmission of the perception message without going through the access and mobility management function AMF. Figure 7 The access and mobility management function AMF described in the above is a higher-level entity in the network element and is far away from the locally deployed base station. If the access and mobility management function AMF is used as the medium for the perception message transmission, the forwarding path will be longer, resulting in a transmission delay of the measurement information, which increases the response time of the measurement perception. Figure 3 As Figure 2 Another similar technical extension and technical optimization bypasses the forwarding of the access and mobility management function AMF, effectively avoiding the use of the access and mobility management function AMF to realize the transmission of perception messages, thereby reducing the transmission delay of measurement information and the response time of measurement perception.

[0102] In step 201, a perception instruction from a converged multi-sensing management function CMSMF is received to send or detect a measurement perception signal according to the perception instruction. The perception instruction is used to instruct the target user equipment UE and / or the target radio access network NG-RAN to detect the measurement perception signal. Those skilled in the art understand that the present invention realizes synaesthesia perception by detecting the measurement perception signal, and in other embodiments, it may be a radio frequency signal, or other types of numerical values, or frequency amplitudes, or even a trigger event to detect perception fluctuations, that is, when receiving the perception instruction from the converged multi-sensing management function CMSMF, the detection of the measurement perception signal is turned on.

[0103] Optionally, the target user equipment UE with perception capability can receive perception signaling, collect perception messages and transmit the information obtained by air interface wireless perception to the fusion multi-sensing management function CMSMF. Optionally, the target user equipment UE can directly establish a session through the local user plane function UPF, and transmit perception signaling and perception messages with the multi-sensing management function CMSMF through the data plane.

[0104] Optionally, the target wireless access network NG-RAN is capable of receiving perception signaling, performing perception tasks and transmitting perception messages. The target wireless access network NG-RAN establishes a control plane connection with the converged multi-sensing management function CMSMF, and transmits wireless perception messages obtained through the air interface through a specific transmission protocol.

[0105] In step 202, the measurement perception signal is sent to the fusion multi-sensor management function CMSMF. In an optional embodiment, it can be determined whether the reporting condition is met in the form of a preset threshold signal. For example, when the measurement perception signal exceeds the preset threshold signal, it is considered that the fluctuation is abnormal at this time and the reporting condition is met, and then the measurement perception signal is sent to the fusion multi-sensor management function CMSMF. In other embodiments, the analysis of the fluctuation of the measurement perception signal can also be completed by the fusion multi-sensor management function CMSMF. At this time, the target user equipment UE and / or the target radio access network NG-RAN will interact with the fusion multi-sensor management function CMSMF in real time to sense the information.

[0113] In step 2021, identification information from the fused multi-sensor management function CMSMF is received, identification feedback information is generated, and a first session channel is established. Information verification and information confirmation are required for both parties to interact. If the target user equipment UE fails to authenticate after receiving the identification information from the fused multi-sensor management function CMSMF, identification feedback information is not generated, or failure information is fed back, and the first session channel cannot be established. Only when the establishment of the first session channel is confirmed, identification feedback information is generated.

[0114] In step 2022, the identification feedback information is sent to the converged multi-sensing management function CMSMF. After the identification feedback information is sent to the converged multi-sensing management function CMSMF, a first session channel between the target user equipment UE and the user plane function UPF is established.
