[0029] The technical solution in this application will be described below with reference to the accompanying drawings.

[0030] Communication system architecture

Optionally, the wireless communication system 100 may include one or more network devices 110 and / or one or more terminal devices 120. For a network device 110, the one or more terminal devices 120 may all be located within the network coverage of the network device 110, or all be located outside the network coverage of the network device 110, or some may be located within the coverage of the network device 110 and others outside the network coverage of the network device 110. This is not limited in the embodiments of the present application.

[0033] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

The cellular phone and smart home devices communicate without relaying the communication signal through the base station.

[0036] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. Base station can broadly cover various names as follows, or replace the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0041] System architecture of 5G network, perception services, and positioning services

[0042] The 5G network system architecture is shown in Figure 2. In this system architecture, the UE establishes an access layer connection with the access node (AN) through the air interface (Uu interface), exchanges access layer messages and wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the access and mobility management function (AMF) through the N1 interface, and exchanges NAS messages. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The policy control function (PCF) is responsible for formulating policies related to UE mobility management, session management, billing, etc. The user plane function (UPF) transmits data with the external data network (DN) through the N6 interface and with the AN through the N3 interface.

[0043] Current cellular networks (including 5G networks) are primarily used for wireless data transmission and communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception. For example, cellular network radio electromagnetic wave signals can be used for user motion or gesture recognition, respiratory monitoring, terminal device movement speed measurement, environmental imaging, weather monitoring, and more. Therefore, cellular networks can also be used to obtain sensory information.

[0044] Currently, there is a discussion on supporting perception capabilities in B5G (beyond 5G) networks. For example, perception capabilities can be supported in the 3rd generation partnership project (3GPP) network by adding perception network elements (or perception control network elements) and corresponding processes. Figure 3 shows an example of a network system architecture that supports perception capabilities. As shown in Figure 3, a perception network element (i.e., the sensing function (SF) in Figure 3) is added to the core network to handle perception-related operations. After the application sends a perception request to the core network of the 3GPP network, the core network can select the correct base station or auxiliary terminal device through the perception network element or AMF, and trigger the base station or auxiliary terminal device to enable the perception-related wireless measurement capability to start the measurement of perception information and generate perception results.

[0045] The main perception links or perception methods of synaesthesia integration scenarios include the following:

[0046] 1. Base station echo sensing link (single base station sensing): The base station sends a sensing signal and receives an echo signal;

[0047] 2. Inter-base station sensing link (base station-base station sensing): Base station B receives the sensing signal sent by base station A;

[0048] 3. Air interface uplink perception link (terminal device-base station uplink perception): The base station receives the perception signal sent by the terminal;

[0049] 4. Air interface downlink perception link (terminal device-base station downlink perception): The terminal device receives the perception signal sent by the base station;

[0050] 5. Terminal echo sensing link (single terminal device sensing): The terminal device sends a sensing signal and receives an echo signal; and

[0051] 6. Inter-terminal perception link (terminal device-terminal device perception): Terminal device B receives the perception signal sent by terminal device A.

[0052] In the early stages of B5G interawareness integration, consideration is given to reusing existing air interface signals as much as possible to perform perception behaviors without introducing excessive air interface enhancements. In addition, considering the complexity of full-duplex implementation, collaborative perception between terminal devices and / or base stations is a priority. Among the perception methods listed above, perception methods 3-6 may require terminal devices to report a large amount of perception data to the perception network elements in the core network or obtain auxiliary data from the core network elements.

[0053] At present, considering that the amount of interactive data between the terminal device and the perception network element is large, the terminal device can transmit data with the perception network element through the user plane to complete the necessary interaction of the perception service. For example, the terminal device can send perception data to the perception network element through the UPF by establishing a protocol data unit (PDU) session (which can be a special PDU session). Taking the perception network element as the SF shown in Figure 3 as an example, in some implementations, the perception network element may include SF-C (SF control plane network element) and SF-U (SF user plane network element). The terminal device can, for example, send perception data to SF-U through the UPF. Of course, SF, SF-C, and SF-U are only examples of the name of the network element. The network element may also use other names, or may be jointly established with the location management function (LMF). This embodiment of the present application does not specifically limit this. At the same time, for some perception tasks, in order to save network resources, the perception node may be allowed to partially process the perception data and transmit a small amount of data to the perception network element through the control plane.

[0054] Figure 4 shows the system architecture of the current positioning service. In this system architecture, the LMF can receive positioning requests through the gateway mobile location center (GMLC), application function (AF), network exposure function (NEF) or AMF. The AMF can then send a positioning task to the terminal device and determine the location of the target device based on the task execution results reported by the terminal device. Similar to the perception service, the positioning service may also require switching between control plane transmission and user plane transmission.

[0055] Configuration and data transmission process of the control plane and user plane of perception / positioning services

[0056] Figure 5 shows the control plane configuration and data transmission process of the sensing / positioning service. The following is a detailed introduction to each step in Figure 5.

[0057] In step S502, the SF / LMF receives a sensing / positioning request from a network element such as the GMLC / AF / NEF / AMF.

[0058] In step S504, SF / LMF sends an N1N2 message transmission request to AMF. The N1N2 message transmission request carries the identification (ID) information of the perception / positioning session. For example, the ID information of the perception / positioning session may include one or more of the following: correlation ID / deferred routing ID / session ID. The correlation ID mentioned here may be a location service correlation identity (LCS correlation ID) or a sensing correlation ID, etc. The ID information of the perception / positioning session can be used to identify the message or request of the control plane. The correlation ID mentioned above can be allocated by AMF in the previous step and sent to SF / LMF; alternatively, the correlation ID can also be generated by SF / LMF itself and sent to AMF. Identification information such as deferred routing ID or session ID can be used to identify periodic perception / positioning sessions.

[0059] In step S506, the AMF sends the perception / positioning message to the terminal device. For example, the AMF can determine the routing ID based on the association ID and then send the routing ID to the terminal device. Alternatively, the AMF can send information such as the deferred routing ID / session ID to the terminal device via a message container. The routing ID / deferred routing ID / session ID is the control plane transmission identifier on the terminal device side. When the terminal device subsequently needs to send data to the LMF / SF via the control plane, it can use this identifier to determine the corresponding LMF / SF and the corresponding perception / positioning session.

[0060] In step S508, after performing the sensing / positioning measurement, the terminal device may send a sensing / positioning data transmission request to the AMF. The sensing / positioning data transmission request may include a routing ID / deferred routing ID / session ID.

[0061] In step S510, after receiving the sensing / positioning data transmission request, the AMF can determine the SF / LMF and the association ID to be used based on the routing ID / deferred routing ID / session ID and the locally stored mapping relationship. The AMF can then send the sensing / positioning data to the SF / LMF.

[0062] In step S512, if the sensing / positioning process has not been completed, steps S504 to S510 may be repeated to continue interacting with sensing / positioning data through the control plane.

[0063] Figure 6 shows the configuration and data transmission process of the user plane of the sensing / positioning service. The following is a detailed introduction to each step in Figure 6.

[0064] In step S602, after receiving the perception / positioning request from the network elements such as GMLC / AF / NEF / AMF, the SF / LMF decides to use the user plane to transmit the perception / positioning data.

[0065] In step S604, the SF / LMF sends an N1N2 message transmission request to the AMF. The N1N2 message transmission request may carry the address information of the SF / LMF. The address information may be, for example, an Internet Protocol (IP) address and / or a fully qualified domain name (FQDN).

[0066] In step S606, the AMF sends the user plane information (SF / LMF address information) to the terminal device.

[0067] In step S608, after receiving the user plane information, the terminal device triggers the session establishment process. For example, the terminal device can match the user plane information with a local user equipment routing policy (URSP) rule to trigger the session establishment process.

[0068] After the session is established in step S610, the terminal device may send a user plane connection establishment request to the user plane SF / LMF via the user plane. For example, the terminal device may establish the user plane connection based on a protocol such as Secure User Plane Location (SUPL). During the connection establishment process, the user plane protocol stack allocates a user plane session ID.

[0069] In step S612, after the connection is established, the terminal device and the SF / LMF perform the user plane perception / positioning process and interact with data through the user plane.

[0070] In wireless communication systems, some services only support a single transmission mode for their data, which is inflexible. For example, positioning services, as well as future sensing services, will involve both control plane data transmission and user plane data transmission. However, both positioning and sensing services inherently support only one data transmission mode for the same service, and do not support switching between control plane and user plane transmission during task execution. This is inflexible for positioning and sensing services, especially those with long-term periodicity, and hinders the full utilization of network resources.

[0071] In order to solve the above problems, the embodiments of the present application are described in detail below with examples.

[0072] Figure 7 is a schematic flow chart of a method for data transmission provided in an embodiment of the present application. The method of Figure 7 can be performed by a first device and a second device. The first device can be a network element in a core network, and the second device can be a terminal device. Alternatively, the first device can be a terminal device, and the second device can be a network element in a core network.

[0073] The method of Figure 7 includes step S710, that is, a first device sends a first message to a second device. The first message can be used to configure control plane transmission and / or user plane transmission.

[0074] In some implementations, the first message may be used to configure user plane transmission. Accordingly, the first device may send the first message to the second device during the process of switching the transmission of service data from control plane transmission to user plane transmission.

[0075] In some implementations, the first message may be used to configure control plane transmission. Accordingly, the first device may send the first message to the second device during the process of switching the transmission of service data from user plane transmission to control plane transmission.

[0076] In some implementations, the first message may be used to configure control plane transmission and user plane transmission (ie, perform dual configuration). Accordingly, the first device may send the first message to the second device during the process of configuring user plane transmission and control plane transmission.

[0077] In some implementations, control plane transmission may also be referred to as or replaced by a control plane connection or a control plane transmission path.

[0078] In some implementations, user plane transmission may also be referred to as or replaced by user plane connection or user plane transmission path.

[0079] Both the control plane transmission and the user plane transmission are used to transmit service data of the first service. The embodiment of the present application does not specifically limit the service type of the first service. For example, the first service may be a positioning service. In another example, the first service may be a sensing service.

[0080] The first message may include first information and second information, wherein the first information is associated with or corresponds to control plane transmission, and the second information is associated with or corresponds to user plane transmission.

[0081] In an embodiment of the present application, the first message (a message used to configure control plane transmission and / or user plane transmission) carries both information corresponding to the control plane transmission and information corresponding to the user plane transmission, which facilitates switching between control plane transmission and user plane transmission.

[0082] In some implementations, the first information may be identification information corresponding to control plane transmission.

[0083] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (the session ID can be used to perceive the service and can also be used to locate the service).

[0084] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0085] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0086] In some implementations, the second information may be identification information corresponding to user plane transmission and / or user plane information used to establish a session.

[0087] In some implementations, the identification information corresponding to the user plane transmission may include a user plane session ID (user plane session identity, UP session ID).

[0088] In some implementations, the user plane information used to establish the session may include address information used to establish the session. The address information may be address information of a network element associated with the first service in the core network, such as address information of the SF and / or address information of the LMF. The address information mentioned here may include one or more of the following: an IP address and a Fully Qualified Domain Name (FQDN).

[0089] The present application is described in more detail below with reference to three embodiments.

[0090] Example 1: Switching from control plane transmission to user plane transmission

[0091] In some implementations, the first message mentioned above may refer to a message sent by the first device to the second device during the process of switching the transmission of service data from control plane transmission to user plane transmission.

[0092] In some implementations, before executing step S710, control plane transmission or control plane-based transmission of service data of the first service may be configured. The control plane transmission configuration and data transmission process can be seen in FIG5 .

[0093] In some implementations, before executing step S710, the second device may first determine whether to switch from control plane transmission to user plane transmission. For example, the second device may determine whether to switch from control plane transmission to user plane transmission based on one or more of the following: control plane signaling transmission load, requirements of the first service (such as latency, accuracy), and the data volume of the service data to be transmitted.

[0094] Example 1.1: The first information may include identification information corresponding to the control plane transmission, and the second information may include user plane information used to establish a session

[0095] In some implementations, the first device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. The second device may be a network element in the core network used for mobility management, such as an AMF. The SF / LMF may send a first message to the AMF, and the first message may carry identification information corresponding to the control plane transmission and user plane information used to establish the session.

[0096] In some implementations, the first device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. The second device may be a terminal device. The SF / LMF may send a first message to the terminal device, and the first message may carry identification information corresponding to the control plane transmission and user plane information used to establish the session. In implementation, the SF / LMF may send the first message to the terminal device via the AMF.

[0097] In some implementations, the first device may be a network element for mobility management in a core network, such as an AMF. The second device may be a terminal device. The AMF may send a first message to the terminal device, and the first message may carry identification information corresponding to control plane transmission and user plane information for establishing a session.

[0098] In some implementations, the first message may be an N1N2 message transmission request. The first message may carry identification information corresponding to control plane transmission and user plane information for establishing a session.

[0099] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (the session ID can be used to perceive the service and can also be used to locate the service).

[0100] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0101] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0102] In some implementations, the user plane information used to establish the session may include address information used to establish the session. The address information may be address information of a network element associated with the first service in the core network, such as address information of the SF and / or address information of the LMF. The address information mentioned here may include one or more of the following: an IP address and a Fully Qualified Domain Name (FQDN).

[0103] Example 1.2: The first information may include identification information corresponding to control plane transmission, and the second information may include identification information corresponding to user plane transmission

[0104] In some implementations, the first device may be a terminal device; the second device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. For example, the terminal device sends a first message to the SF / LMF, where the first message carries identification information corresponding to control plane transmission and identification information corresponding to user plane transmission.

[0105] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (the session ID can be used to perceive the service and can also be used to locate the service).

[0106] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0107] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0108] In some implementations, the identification information corresponding to the user plane transmission may include a user plane session ID.

[0109] In some implementations, the first message may be a user plane connection establishment request message.

[0110] In some implementations, the second device establishes an association relationship between the identification information corresponding to the control plane transmission and the identification information corresponding to the user plane transmission. For example, the first device is a terminal device, and the second device is an SF / LMF. The terminal device can send a first message (user plane connection establishment request message) to the SF / LMF. In addition to carrying the user plane session ID in the user plane connection establishment request message, the terminal device also carries the ID information corresponding to the control plane transmission (such as LCS association ID / deferred routing ID / session ID). In this way, the SF / LMF can determine the control plane connection corresponding to the user plane connection based on the ID information corresponding to the control plane transmission, and maintain the association relationship between the user plane session ID and the ID corresponding to the control plane. The establishment of this association relationship helps to transmit the control plane data (such as data that has not been transmitted before) through the user plane to avoid data loss.

[0111] The following describes Embodiment 1 in more detail with reference to specific examples. It should be noted that the example of FIG8 is merely intended to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or variations based on the example of FIG8, and such modifications or variations also fall within the scope of the embodiments of the present application.

[0112] In the example of Figure 8, when the SF / LMF decides to switch the data transmission mode from control plane transmission to user plane transmission, the SF / LMF simultaneously sends the ID information corresponding to the control plane transmission to the terminal device. When the terminal device requests to establish a user plane connection, it also carries the ID information corresponding to the control plane transmission. The ID information corresponding to the control plane transmission can be used by the SF / LMF to associate and map the control plane transmission and user plane transmission.

[0113] In step S802, referring to the control plane configuration and data transmission process shown in FIG5, the terminal device establishes a control plane connection with the SF / LMF and performs data transmission through the control plane connection.

[0114] In step S804, the SF / LMF decides to switch subsequent data transmission to user plane transmission. For example, the SF / LMF may make this decision based on the signaling transmission load, the amount of service data to be transmitted, and the requirements of the sensing / positioning service (such as latency and accuracy).

[0115] In step S806, the SF / LMF sends an N1N2 message transmission request to the AMF. The N1N2 message transmission request may carry the address information of the SF / LMF. This address information may be, for example, an IP address and / or Fully Qualified Domain Name (FQDN). Furthermore, the N1N2 message transmission request may also carry ID information corresponding to control plane transmission, such as the LCS association ID / deferred routing ID / session ID (the session ID may be used for service awareness and positioning services).

[0116] In step S808, the AMF sends the user plane information (SF / LMF address information) to the terminal device. At the same time, the message carrying the user plane information also carries the ID information corresponding to the control plane transmission, such as LCS association ID / deferred routing ID / session ID, etc.

[0117] In step S810, after receiving the user plane information, the terminal device triggers the session establishment process. For example, the terminal device may match the local URSP rule through the user plane information, thereby triggering the session establishment process.

[0118] In step S812, after the session is established, the terminal device sends a user plane connection establishment request to the SF / LMF. This connection establishment request can establish a user plane connection using a protocol similar to SUPL. During the user plane connection establishment process, the user plane protocol stack assigns a user plane session ID. This message also carries ID information corresponding to control plane transmission, such as the LCS association ID, deferred routing ID, and session ID.

[0119] In step S814, the SF / LMF determines the control plane connection corresponding to the user plane connection based on the LCS association ID / deferred routing ID / session ID carried in the user plane connection establishment request from the terminal device. The SF / LMF can maintain the association between the user plane session ID and the identifier corresponding to the control plane transmission and perform subsequent user plane data exchange based on this association.

[0120] Figure 8 provides a solution for switching data transmission for sensing / positioning services from control plane transmission to user plane transmission. This solution establishes and maintains an association between control plane transmission and user plane transmission by carrying the corresponding ID information for the control plane transmission during user plane connection establishment, thereby ensuring normal subsequent data transmission and identification. The solution provided in Figure 8 allows sensing / positioning services to flexibly switch from control plane transmission to user plane transmission based on actual conditions.

[0121] Example 2: Switching from user plane transmission to control plane transmission

[0122] In some implementations, the first message mentioned above may refer to a message sent by the first device to the second device during the process of switching the transmission of service data from user plane transmission to control plane transmission.

[0123] In some implementations, before executing step S710, user plane transmission or user plane-based transmission of service data of the first service may be configured. The configuration of user plane transmission and the data transmission process can be seen in FIG6 .

[0124] In some implementations, before executing step S710, the second device may first determine whether to switch from user plane transmission to control plane transmission. For example, the second device may determine whether to switch from user plane transmission to control plane transmission based on one or more of the following: control plane signaling transmission load, requirements of the first service (such as latency, accuracy), energy consumption of the terminal device, and the data volume of the service data to be transmitted.

[0125] In some implementations, the first information may include identification information corresponding to control plane transmission, and the second information may include identification information corresponding to user plane transmission.

[0126] In some implementations, the first device may be a network element in the core network for sensing or positioning, such as an SF or LMF. The second device may be a network element in the core network for mobility management, such as an AMF. The SF / LMF may send a first message to the AMF, and the first message may carry identification information corresponding to control plane transmission and identification information corresponding to user plane transmission.

[0127] In some implementations, the first device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. The second device may be a terminal device. The SF / LMF may send a first message to the terminal device, and the first message may carry identification information corresponding to control plane transmission and identification information corresponding to user plane transmission. During implementation, the SF / LMF may send the first message to the terminal device via the AMF.

[0128] In some implementations, the first device may be a network element for mobility management in a core network, such as an AMF. The second device may be a terminal device. The AMF may send a first message to the terminal device, and the first message may carry identification information corresponding to control plane transmission and identification information corresponding to user plane transmission.

[0129] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (for example, the session ID can be used to perceive the service or to locate the service).

[0130] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0131] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0132] In some implementations, the identification information corresponding to the user plane transmission may include a user plane session ID.

[0133] In some implementations, the second device can establish an association relationship between identification information corresponding to the control plane transmission and identification information corresponding to the user plane transmission. For example, the second device is a terminal device, and the first device is a network element in the core network. The second device receives a perception / positioning message, which carries not only the ID information corresponding to the control plane transmission (such as LCS association ID / deferred routing ID / session ID), but also the user plane session ID. The terminal device can determine the control plane connection corresponding to the user plane connection based on the perception / positioning message, and maintain the association relationship between the user plane session ID and the control plane ID. For example, the terminal device can map the service data corresponding to the subsequent user plane session to the control plane based on the association relationship, and send it to the SF / LMF through the control plane.

[0134] The second embodiment is described in more detail below with reference to specific examples. It should be noted that the example of FIG. 9 is merely intended to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the example of FIG. 9, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0135] In the example of Figure 9, when the SF / LMF decides to switch the data transmission mode from user plane transmission to control plane transmission, the SF / LMF simultaneously sends the ID information corresponding to the user plane transmission to the terminal device. The terminal device can map the user plane session ID and the identifier corresponding to the control plane transmission, and transmit subsequent user plane data to be transmitted to the SF / LMF via the control plane connection based on this mapping relationship.

[0136] In step S902, referring to the configuration of user plane transmission and the data transmission process shown in FIG6, the terminal device establishes a user plane connection with the SF / LMF and performs data transmission.

[0137] In step S904, the SF / LMF decides to switch from user transmission to control plane transmission. For example, the SF / LMF may make this decision based on signaling transmission load, sensing / positioning service requirements (such as latency and accuracy), terminal device energy consumption, and the amount of service data to be transmitted.

[0138] In step S906, the SF / LMF sends an N1N2 message transmission request to the AMF. The N1N2 message transmission request carries the ID information corresponding to the control plane transmission of the sensing / positioning session. The ID information corresponding to the control plane transmission may be, for example, an association ID / deferred routing ID / session ID (the session ID may be used for sensing services as well as positioning services). In addition, the N1N2 message transmission request also carries ID information corresponding to the user plane transmission, such as the user plane session ID. The user plane session ID may be allocated by the user plane protocol stack. The user plane protocol stack may be, for example, the LTE positioning protocol (LPP), the lower-level SUPL protocol, or a new protocol that will emerge in the future.

[0139] In step S908, the AMF sends the perception / positioning message to the terminal device. For example, the AMF can determine the routing ID based on the association ID, and then send the routing ID to the terminal device. Alternatively, the AMF can also carry information such as the deferred routing ID / session ID in a message container and send it to the terminal device. The routing ID / deferred routing ID / session ID is the ID information corresponding to the control plane transmission used on the terminal device side. In other words, if the terminal device subsequently sends the service data of the perception / positioning service from the control plane to the LMF / SF, the ID information can be used to determine the corresponding LMF / SF and the corresponding perception / positioning session. In addition, the perception / positioning message sent in step S908 also carries the ID information corresponding to the user plane transmission, such as the user plane session ID.

[0140] In step S910, the terminal device may establish and maintain an association between the LCS association ID / deferred routing ID / session ID and the user plane session ID (i.e., bind the two together), and perform subsequent control plane transmission based on the association. For example, the terminal device may map data corresponding to the user plane session ID to the control plane, thereby transmitting the data to the SF / LMF via the control plane.

[0141] In step S912, the terminal device and the SF / LMF perform the perception / positioning process of the control plane and transmit the perception / positioning data through the control plane.

[0142] Figure 9 provides a solution for switching data transmission for sensing / positioning services from user plane transmission to control plane transmission. This solution establishes and maintains an association between control plane transmission and user plane transmission by carrying the ID information corresponding to the user plane transmission during the control plane connection establishment process, thereby ensuring normal subsequent data transmission and identification. The solution provided in Figure 9 allows sensing / positioning services to flexibly switch from user plane transmission to control plane transmission based on actual conditions.

[0143] Example 3: Configuring user plane transmission and control plane transmission simultaneously

[0144] In the third embodiment, the first message mentioned above may refer to a message sent by the first device to the second device during the process of configuring user plane transmission and control plane transmission.

[0145] In the third embodiment, before executing step S710, the second device may first determine whether to configure user plane transmission and control plane transmission simultaneously (or whether to perform dual configuration of user plane transmission and control plane transmission). For example, the second device may determine whether to configure user plane transmission and control plane transmission simultaneously based on one or more of the following: signaling transmission load of the control plane, requirements of the first service (such as latency, accuracy), energy consumption of the terminal device, service requirements of the first service, and data volume of service data to be transmitted.

[0146] Example 3.1: The first information includes identification information corresponding to the control plane transmission, and the second information includes user plane information for establishing a session

[0147] In some implementations, the first device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. The second device may be a network element in the core network used for mobility management, such as an AMF. The SF / LMF may send a first message to the AMF, and the first message may carry identification information corresponding to the control plane transmission and user plane information used to establish the session.

[0148] In some implementations, the first device may be a network element in the core network used for sensing or positioning, such as an SF or LMF. The second device may be a terminal device. The SF / LMF may send a first message to the terminal device, and the first message may carry identification information corresponding to the control plane transmission and user plane information used to establish the session. In implementation, the SF / LMF may send the first message to the terminal device via the AMF.

[0149] In some implementations, the first device may be a network element for mobility management in a core network, such as an AMF. The second device may be a terminal device. The AMF may send a first message to the terminal device, and the first message may carry identification information corresponding to control plane transmission and user plane information for establishing a session.

[0150] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (the session ID can be used to perceive the service and can also be used to locate the service).

[0151] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0152] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0153] In some implementations, the user plane information used to establish the session may include address information used to establish the session. The address information may be address information of a network element associated with the first service in the core network, such as address information of the SF and / or address information of the LMF. The address information mentioned here may include one or more of the following: an IP address and a Fully Qualified Domain Name (FQDN).

[0154] In some implementations, the first message may further include third information. The third information may be used to indicate one or more of the following: whether the first service supports switching between control plane transmission and user plane transmission; and switching conditions between control plane transmission and user plane transmission. Furthermore, in some implementations, after receiving the third information, the second device may determine whether to use control plane transmission and / or user plane transmission based on the switching conditions indicated by the third information.

[0155] In some implementations, the switching condition between control plane transmission and user plane transmission may be associated with one or more of the following: a service requirement of the first service, and a transmission status of a current transmission path. The current transmission path referred to here is a transmission path corresponding to user plane transmission or a transmission path corresponding to control plane transmission.

[0156] In some implementations, the switching condition is associated with one or more of the following: the service data volume of the first service, the congestion condition of the current transmission path, the transmission delay requirement of the first service, and the power consumption requirement of the terminal device transmitting the first service.

[0157] For example, if the service data volume of the first service is greater than or equal to a first threshold, the service data of the first service is transmitted using the user plane.

[0158] For another example, if the service data volume of the first service is less than a first threshold, the service data of the first service is transmitted using the control plane.

[0159] For another example, if congestion occurs on the current transmission path, another transmission path is used to transmit the service data of the first service.

[0160] For another example, if the first service has a high requirement on transmission delay (eg, higher than or equal to a second threshold), the service data of the first service is transmitted using the user plane.

[0161] For another example, if the first service has a low requirement on transmission delay (eg, lower than a second threshold), the control plane is used to transmit service data of the first service.

[0162] For another example, if the first service has low power consumption requirements for the terminal device (such as lower than a third threshold), the control plane is used to transmit service data of the first service.

[0163] For another example, if the terminal device detects that the received power of a certain signal exceeds the fourth threshold, the user plane is used to transmit the service data of the first service. The signal can be, for example, a measurement signal emitted during the positioning or perception process. For example, during the positioning process, when it is uncertain whether there is a target device to be located around the terminal device, the control plane can be used to transmit the service data of the first service first, and the measurement signal can be used to measure whether there is a target device around the terminal device. When the received power of the measurement signal exceeds the fourth threshold (which means that there is a target device around the terminal device), it means that a large amount of positioning-related data will be transmitted next. At this time, the service data of the first service can be switched to the user plane.

[0164] For another example, if the terminal device determines that there is no need to report the service data of the first service within a period of time, it can switch from user plane transmission to control plane transmission.

[0165] Example 3.2: The first information includes the identification information corresponding to the control plane transmission, and the second information includes the identification information corresponding to the user plane transmission

[0166] In some implementations, the first device is a terminal device; the second device is a network element in the core network used for sensing or positioning, such as an SF or LMF. For example, the terminal device may send a first message to the SF / LMF, where the first message carries identification information corresponding to control plane transmission and identification information corresponding to user plane transmission.

[0167] In some implementations, the identification information corresponding to the control plane transmission includes one or more of the following: an association ID corresponding to the first service; a deferred routing ID corresponding to the first service; and a session ID corresponding to the first service (the session ID can be used to perceive the service and can also be used to locate the service).

[0168] For example, the first service is a positioning service, and the corresponding identification information transmitted by the control plane may include an LCS association ID and / or a deferred routing ID.

[0169] For another example, the first service is a perception service, and the corresponding identification information transmitted by the control plane may include a perception session ID.

[0170] In some implementations, the identification information corresponding to the user plane transmission may include a user plane session ID.

[0171] In some implementations, after receiving the first message, the second device can establish an association relationship between the identification information corresponding to the control plane transmission and the identification information corresponding to the user plane transmission. For example, the first device is a terminal device, and the second device is an SF / LMF. The terminal device can send a first message (user plane connection establishment request message) to the SF / LMF. In addition to carrying the user plane session ID in the user plane connection establishment request message, the terminal device also carries the ID corresponding to the control plane transmission (such as LCS association ID / deferred routing ID / session ID). In this way, the SF / LMF can determine the control plane connection corresponding to the user plane connection based on the identifier corresponding to the control plane transmission, and maintain the association relationship between the user plane session ID and the control plane identifier. The establishment of this association relationship helps to transmit the control plane data (such as data that has not been transmitted before) through the user plane to avoid data loss.

[0172] The following describes the third embodiment in more detail with reference to specific examples. It should be noted that the example of FIG10 is merely to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the example of FIG10 given, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0173] The transport connection configuration process shown in Figure 10 configures both user plane and control plane transmission for the sensing / positioning service. During the configuration process, the ID information corresponding to the control plane transmission and the user plane address information are carried. After configuring the user plane and control plane transmission, the terminal device can independently decide whether to use control plane or user plane transmission to transmit sensing / positioning data based on actual transmission conditions.

[0174] In step S1002, the SF / LMF decides to perform dual configuration, i.e., to simultaneously configure user plane transmission and control plane transmission for the sensing / positioning service. For example, the SF / LMF may make this decision based on signaling transmission load, sensing / positioning service requirements (e.g., latency, accuracy), terminal device energy consumption, and the amount of service data to be transmitted. Alternatively, the SF / LMF may make this decision based on the service type and / or service requirements of the sensing / positioning service.

[0175] In step S1004, the SF / LMF sends an N1N2 message transmission request to the AMF. This N1N2 message transmission request carries the address information of the SF / LMF, such as an IP address or Fully Qualified Domain Name (FQDN). Furthermore, the N1N2 message transmission request also carries ID information corresponding to control plane transmission, such as the LCS association ID / deferred routing ID / session ID (this session ID can be used for both sensing services and positioning services). Furthermore, the N1N2 message transmission request may also carry indication information (corresponding to the third information mentioned above), which can be used to indicate that the sensing / positioning service supports switching between user plane transmission and control plane transmission. Furthermore, this indication information may also simultaneously indicate the conditions for switching between user plane transmission and control plane transmission. For example, when the terminal device detects that certain switching conditions are met, it may switch from control plane transmission to user plane transmission. For example, if the data volume of the positioning sensing service exceeds a certain threshold or if the received power of the sensing / positioning measurement signal exceeds a certain threshold, the terminal device may switch to user plane transmission. Alternatively, if the terminal device detects that no sensing / positioning data needs to be reported for a period of time, it may switch to control plane transmission.

[0176] In step S1006, the AMF sends the user plane information (SF / LMF address information) to the terminal device. The message carrying the user plane information may also carry ID information corresponding to control plane transmission, such as the LCS association ID / deferred routing ID / session ID. Furthermore, the message carrying the user plane information also carries the indication information mentioned above.

[0177] In step S1008, the terminal device monitors the triggering conditions of the perception / positioning service according to the configuration information sent by the SF / LMF.

[0178] In step S1010, the terminal device performs measurement of the sensing / positioning signal.

[0179] In step S1012, the terminal device selects a data transmission mode according to the instruction information sent by the SF / LMF.

[0180] In step S1014a, after performing the measurement, the terminal device sends a sensing / positioning data transmission request to the AMF. The sensing / positioning data transmission request includes the route ID / deferred route ID / session ID.

[0181] In step S1014b, after receiving the sensing / positioning data transmission request, the AMF determines the SF / LMF and the association ID to be used based on the routing ID / deferred routing ID / session ID and the previously stored mapping relationship. The AMF then sends the sensing / positioning data to the SF / LMF.

[0182] In step S1016a, after receiving the user plane information, the terminal device triggers the session establishment process. For example, the terminal device can match the local URSP rules through the user plane information to trigger the session establishment process.

[0183] After the session is established in step S1016b, the terminal device sends a user plane connection establishment request to the SF / LMF via the user plane. For example, the terminal device may establish the user plane connection using a protocol such as SUPL. During the user plane connection establishment process, the user plane protocol stack assigns a user plane session ID. The user plane connection establishment request also carries ID information corresponding to control plane transmission, such as the LCS association ID / deferred routing ID / session ID.

[0184] In step S1016c, the SF / LMF determines the control plane connection corresponding to the user plane connection based on the LCS association ID / deferred routing ID / session ID sent by the terminal device on the user plane. The SF / LMF may maintain an association between the user plane session ID and the ID information corresponding to the control plane transmission (i.e., bind the user plane session ID and the ID information corresponding to the control plane transmission together) and perform subsequent user plane data transmission based on this association.

[0185] The solution provided in Figure 10 carries the ID information corresponding to the control plane transmission and the address information of the user plane during the transmission connection configuration process, thereby allowing the terminal device to decide whether to use the control plane or user plane for data transmission in subsequent interactions, thereby making the transmission of perception / positioning data more flexible.
