In the wireless communication technology (vehicle to everything, V2X) for vehicles, the advanced driving assistance system (Advanced Driving Assistance System, ADAS) can sense the surrounding environment at any time during driving by using various sensors (for example, millimeter wave radar, lidar, monocular/binocular cameras, satellite navigation, etc.) mounted on the vehicle, collect data, identify, detect and track static and dynamic objects, and can perform calculation and analysis of the system in combination with navigation map data, so that a driver can recognize possible dangers in advance, and the driving comfort and safety are effectively improved.
Integrated sensing and communication in the third generation partnership project (3rd generation partnership project,3GPP) 5G system means that sensing capabilities are provided by the 5G New Radio (NR) wireless communication system and infrastructure that can also be used for communication, and sensing information can come from radio frequency and/or non-radio frequency based sensors. In general, integrated awareness and communication may relate to the scenario of awareness-assisted communication, e.g., a 5G communication system may provide awareness services or awareness-assisted communication. For example, perceptual information related to the communication channel or environment can be used to improve the communication services of the 5G system itself. As one example, the awareness information may be used to assist in radio resource management, interference mitigation, beam management, mobility management, and the like.
The perception of wireless communication channels and environments may further improve the performance of the communication system. Some examples of perceptually assisted communication scenarios are:
(1) The position and the channel environment of the terminal equipment are perceived, the beam scanning range is reduced, and the beam training time is shortened.
(2) And the position, the speed, the motion trail and the channel environment of the terminal equipment are perceived to carry out beam prediction, so that the overhead of beam measurement and the delay of beam tracking are reduced.
(3) The properties of the terminal device and the channel environment are perceived to improve the performance of channel estimation.

Recently issued technical reports of the 5G automotive association (5G-automotive association,5 GAA) illustrate the roles that operators may play in enhancing V2X type services, particularly in infrastructure-assisted context awareness, infrastructure-based remote driving, high definition map collection and sharing, and remote driving support.
Based on the above analysis, research into 3 GPP-based awareness technologies (e.g., NR-based awareness) can have an opportunity to enhance advanced driving assistance systems ADASs.

In summary, through receiving the second sensing request sent by the core network device, the second sensing request is used for requesting to obtain real-time sensing information, sensing the wireless communication environment around the second terminal device to obtain the real-time sensing information, and sending the real-time sensing information to the core network device, so that the first terminal device can obtain the sensing result of at least one other communication device nearby through communication with the core network device, and on the basis that the first terminal device senses through the sensor, the first terminal device is assisted to sense through the wireless communication system, thereby effectively improving the reliability of sensing the surrounding environment by the first terminal device and effectively improving the quality of the sensing result.
As an example, in any embodiment of the present application, the architecture of the communication system referred to in the present application may refer to fig. 11, and fig. 11 is a schematic diagram of the architecture of another communication system provided in the embodiment of the present application, as shown in fig. 11, where the SAF may communicate with the AMF through a UPF (the user plane function, user plane function) and an SMF. The first terminal device in each embodiment of the present application is the first terminal device in fig. 11, the second terminal device in each embodiment of the present application is the second terminal device in fig. 11, and the first access network device and the second access network device in each embodiment of the present application are both included in the access network RAN in fig. 11, which can be understood that the RAN in fig. 11 may include multiple access network devices. The first terminal device and the second terminal device can communicate with the AMF and the UPF through the access network device, further communicate with the SMF through the AMF, and communicate with the SAF through the UPF. Where the SAF is owned or trusted by the mobile operator, e.g., perceives that there is a reliable business and technical relationship between the application owner and the mobile operator. The SAF may also authenticate and authorize communication devices to sense, where sensing parameters (e.g., location, range, time, radio frequency) may also be configured by the SAF.
As yet another example, further, the first terminal device is a vehicle (vehicle), and the first terminal device may include an advanced driving assistance system ADAS, a 3GPP awareness module, a 3GPP communication module, and a non-3 GPP sensor therein. Wherein the 3GPP awareness module performs awareness using 3GPP technology as a transmitter and/or receiver, which can provide awareness data as input to the ADAS. The 3GPP awareness module can be connected to the SAF for awareness control purposes, which can request awareness data from the SAF when the ADAS needs awareness data from the 3GPP network as input. The 3GPP communication module is a module for communicating with a 3GPP network, at least supporting registration, establishing a PDU session with the 3GPP network, and transmitting/receiving traffic (e.g., IP data) to/from the network. ADAS is a perceived initiator and consumer that sends a perceived request to a 3GPP perceived module, receives and consumes perceived data from the 3GPP perceived module. Non-3 GPP sensors include millimeter wave radar, lidar, monocular/binocular cameras, satellite navigation, etc., which can provide sensory data input for an ADAS.
As an example, in any embodiment of the present application, taking a core network device as an SAF, a first terminal device as a vehicle, and both a second terminal device and a second access network device to perform sensing as an example, a flow of a sensing service acquisition method provided in the embodiment of the present application may be as shown in fig. 12, and may specifically include the following steps:
1. When the vehicle needs to perceive the surrounding environment, for example: the vehicle travels on the road, and the ADAS sends a perception request to the 3GPP perception module requesting to input perception data, wherein the perception request includes a travel route.
The 3GPP awareness module sends awareness requests to the SAF, including awareness mode (e.g., awareness results from transmitters and receivers, requiring other awareness clients) and travel routes.
And 3, the SAF authorizes the perception request sent by the first terminal equipment according to the pre-configured security policy, and sends confirmation of the perception mode and the driving route to the first terminal equipment, so that the first terminal equipment is authorized to acquire the perception data on the driving route.
After receiving the confirmation, the 3GPP communication module and the 3GPP perception module send a perception response to the ADAS, wherein the perception response comprises a request for the real-time position of the vehicle.
5, carrying real-time sensing results of the real-time position request of the vehicle by the ADAS; the 3GPP perception module sends a real-time perception result request to the SAF, wherein the request comprises the real-time position of the vehicle; the SAF selects a second terminal device and a second access network device (such as a gNB) that are aware of the vicinity of the location based on the real-time location of the vehicle, and then requests real-time awareness results from the second terminal device and/or the second access network device.
6. The selected second terminal equipment and the second access network equipment send the real-time sensing result to the SAF, and send the real-time sensing result to the ADAS through a 3GPP communication module and a 3GPP sensing module in the vehicle; in addition, the 3GPP perception module can also carry out perception and send the perception result to the ADAS.
As an example, in any embodiment of the present application, taking a core network device as an SAF, a first terminal device as a vehicle, and both a second terminal device and a second access network device (denoted by RAN in the figure) to perform sensing as an example, a flow of a sensing registration method of the second terminal device and the second access network device provided in the embodiment of the present application may be shown in fig. 13, and may specifically include the following steps:
1. the second terminal device sends a registration request to the AMF through the RAN, wherein the registration request includes registration parameters, such as: registration type, second terminal device identity (such as sui (Subscription Concealed Identifier, subscriber implicit identity) or 5G-GUTI (5G Globally Unique Temporary UE Identity,5G globally unique temporary user equipment identity) or PEI (Permanent Equipment Identifier, permanent device identity)), security parameters, etc. After authenticating and authorizing the second terminal equipment, the AMF sends a registration acceptance message (Registration Accept) to the second terminal equipment to finish the registration of the second terminal equipment.
2. The second terminal device initiates a PDU session establishment procedure requested by the second terminal device by transmitting a NAS (Non Access Stratum, non-access) message comprising an N1SM container containing the PDU session establishment request. The AMF receives a PDU session establishment request from a second terminal device.
AMF selects an SMF and sends an Nsmf_PDUSation_CreateSMContext request to the SMF, comprising: the second terminal device requesting an indication of the IP address of a SAF and/or protocol configuration options (Protocol Configuration Option, PCO) regarding the terminal device capabilities supporting the awareness function; the SMF receives the NSmf_PDUSion_CreateSMContext request and responds to the AMF.
The SMF sends an N4 session establishment request to the UPF to establish a new PDU session for the second terminal device.
The smf sends namf_communication_n1n2message transfer to the AMF including the IP address assigned to the second terminal device.
AMF receives Namf_communication_N1N2MessageTransferand sends an N2 PDU session request (NAS message) to the RAN (gNB), including the IP address assigned to the second terminal device.
7. During access network Specific (AN-Specific) resource setting, the gNB forwards the NAS message (PDU session establishment accept) provided in step 6 to the second terminal device, including the IP address assigned to the second terminal device.
8. The second terminal device configures an IP address and sends a sensing registration (including a location of the second terminal device and a sensing capability of the second terminal device) to the SAF according to the received PDU session establishment acceptance, a server domain name or the IP address of the SAF may be pre-configured in the second terminal device, and the sensing capability of the second terminal device may include a sensing range of the second terminal device; the SAF accepts the registration and responds to the second terminal device.
The RAN (gNB) sends a perceived registration (including a location of the RAN and a perceived capability of the RAN) to the SAF, a server domain name or an IP address of the SAF may be preconfigured in the RAN, and the perceived capability of the RAN may include a perceived range of the RAN; the SAF accepts registration and responds to the RAN.
It can be understood that in the embodiments of fig. 9 to fig. 10 of the present application, before the second terminal device sends the third sensing registration request to the core network device through the second access network device, the second terminal device can send the registration request to the AMF through the second access network device, and complete the registration, and can complete the establishment of the PDU session based on the AMF and the SMF, which can be achieved through steps 1 to 7 in fig. 13.
It is also understood that the RAN in fig. 13 may include at least one second access network device.
As an example, in any embodiment of the present application, taking a core network device as an SAF, a first terminal device (first terminal device) as a vehicle, and both a second terminal device and a second access network device perform sensing as an example, a flow of a sensing registration method of the first terminal device provided in the embodiment of the present application may be as shown in fig. 14, and specifically may include the following steps:
the 3GPP communication module sends a registration request to the AMF through a first access network device (denoted by RAN (gNB) in the figure), where the registration request includes registration parameters, for example: registration type, first terminal equipment identity (such as SUCI or 5G-GUTI or PEI), security parameters, etc. After authenticating and authorizing the first terminal equipment, the AMF sends a registration acceptance message (Registration Accept) to the first terminal equipment, and completes the registration of the first terminal equipment to the 5G core network (5G core,5 GC).
The 3GPP communication module initiates the PDU session establishment procedure requested by the first terminal device by transmitting a NAS message containing the PDU session establishment request within the N1SM container. The AMF receives a PDU session establishment request from the first terminal device and sends the PDU session establishment request to the SMF. The SMF sends an N4 session establishment request to the UPF to establish a new PDU session for the first terminal device. The SMF allocates a new IP address to the first terminal device and sends it to the first terminal device via the AMF and the RAN (gNB).
The 3.3 GPP perception module initiates a registration request to the SAF for perception, wherein the registration request comprises a first terminal equipment ID (such as SUPI or MSISDN), the registration request can also comprise a terminal equipment type, and the first terminal equipment is reported as a vehicle.
4. According to a security policy pre-configured in the SAF by an operator, the SAF accepts the registration of the first terminal equipment and responds to the successful registration of the first terminal equipment.
It can be understood that in the embodiments of fig. 5 to fig. 6 of the present application, before sending the first perceived registration request to the core network device, the first terminal device can send the registration request to the AMF and complete the registration, and can complete the establishment of the PDU session based on the AMF and the SMF, which can be achieved through step 1-2 in fig. 14.
