The method for acquiring perception data can comprise the following steps: deriving perceptual data by comparing the emission signal with the response signal, the method being used to find static objects; alternatively, the perception data is derived by analyzing history information of changes in the phase and amplitude of the received signal, a method commonly used to find moving objects.

At present, functions of acquiring perception data (for example, a dynamic 3D map, object information around a vehicle, distance/direction information between a certain vehicle and a surrounding vehicle, and the like) are mainly implemented by application servers of an application layer, which requires that each application server can support perception-related functions, thereby increasing implementation complexity and maintenance difficulty of the application layer.

Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

At present, the function of obtaining perception data (e.g., dynamic 3D maps, object information around a vehicle, distance/direction information between a certain vehicle and a surrounding vehicle, etc.) is mainly implemented by application servers of an application layer.

In view of the above problems, the present application proposes to set a sensing function entity in a mobile communication network architecture, where the sensing function entity is a functional entity that is set for a mobile communication network to support a sensing function, and the sensing function entity is responsible for collecting sensing data and also can support processing of the sensing data to form data, such as an image or a map, required by an application. When each node (such as a terminal (User Equipment, UE), a network device, or an external application) on the network needs to acquire the sensing data, a request may be sent to the sensing function entity to request the sensing function entity to provide the sensing data, and the sensing function entity may acquire corresponding sensing data according to the received request and provide the corresponding sensing data to each node on the network.

The sensing function entity may be located at the core network side or at the radio access network side. The sensing functional entity may be an independent functional entity, or may be located in an existing core Network element or a Radio Access Network (RAN) node. The sensing functional entity may interact directly with each core network element, may also support directly interacting with an Application Function (AF), and may also support directly interacting with a terminal or a RAN node.

Based on the sensing function entity in the mobile communication network, each application server in the application layer can no longer support the acquisition function of the sensing data, and when the application server needs to acquire the sensing data, the application server can directly request the sensing data from the sensing function entity through the mobile communication network, so that the realization complexity and the maintenance difficulty of the existing application layer are reduced.

Fig. 1 is a schematic flow diagram of a sensing data transmission method provided in an embodiment of the present application, where the method is applied to a sensing function entity, and as shown in fig. 1, the method includes the following steps:

step 100, receiving a first request message, wherein the first request message is used for requesting sensing data;

specifically, in this embodiment, the sensing data may be measurement data obtained by performing sensing measurement on a device (for example, a terminal) supporting a sensing function, or may also be data obtained by processing the measurement data.

When each node (such as a terminal, a network device, or an external application) on the network needs to acquire the sensing data, a request may be sent to the sensing function entity in the network to request the sensing function entity to provide the sensing data, and the sensing function entity may determine corresponding sensing data according to the received request and provide the corresponding sensing data to each node on the network.

In this embodiment of the present application, a sensing function entity may receive a first request message sent by various network function entities, application function entities, or terminals, where the first request message is used to request sensing data from the sensing function entity.

The Network functional entity may refer to any Network functional entity that requests sensing data, such as a Network open Function (NEF), a Location Management Function (LMF), a Policy Control Function (PCF), or a RAN node.

Step 101, determining sensing data meeting a first request message based on the first request message;

specifically, after receiving the first request message, the sensing function entity may determine corresponding sensing data according to the first request message, for example, the sensing data meeting the first request message may be determined from locally stored sensing data, or the sensing data meeting the first request message may be acquired from another device such as a RAN node or a terminal.

And 102, transmitting the sensing data to first communication equipment needing the sensing data.

Specifically, after determining the sensing data satisfying the first request message, the sensing functional entity may transmit the sensing data to a first communication device, such as a network functional entity or an application functional entity or a terminal, that needs to sense the data. The first communication device may be a communication device that sends the first request message, or may be a device other than the communication device that sends the first request message, that is, the communication device that sends the first request message may be a device that requests the sensing functional entity for sensing data after receiving the sensing request of the first communication device, and the first request message may carry information of the first communication device to instruct the sensing functional entity to transmit the sensing data to the first communication device corresponding to the information.

According to the sensing data transmission method provided by the embodiment of the application, the sensing function entity is arranged in the mobile communication network, and other network nodes are supported to acquire the sensing data from the sensing function entity, so that any communication equipment can acquire the sensing data through the mobile communication network without supporting the sensing data acquisition function, the complexity, the maintenance difficulty and the production cost of each communication equipment are reduced, and effective sensing data support can be provided for each communication equipment through the mobile communication network.

determining sensing data meeting the attribute information based on the attribute information of the sensing data to be requested, which is contained in the first request message;

Specifically, after receiving the first request message, the sensing functional entity may determine, according to attribute information, the sensing data that satisfies the first request message if the first request message includes attribute information of the sensing data to be requested, such as one or more items of data type information, area information terminal identifier, quality of service QoS, and time information.

The data type information may be a sensing data type, such as an automatic driving type, a dynamic map type, a home application control type, a distance, a direction, an angle, an environment, and the like, or may be an identifier of an application function entity that requests the sensing data. The area information may be a geographical area, a terminal identity or a RAN node identity, etc. The time information may be a start collecting/sensing/measuring time, an end collecting/sensing/measuring time, a sensing period, and the like.

determining, based on the first request message, a second communication device capable of providing the sensory data satisfying the first request message;

and acquiring the sensing data from the second communication equipment, and determining the acquired sensing data as the sensing data meeting the first request message.

Specifically, after receiving the first request message, the sensing functional entity may determine, according to the relevant information of the sensing data to be requested, such as data type information and area information, included in the first request message, the second communication device that can provide the sensing data meeting the first request message, and acquire the sensing data from the second communication device. For example, if the sensing data of a specific area needs to be acquired, the second communication device may be selected according to the area information; if the sensing data of the specific terminal needs to be acquired, the second communication device may be selected according to the location information of the terminal, or the RAN node information serving the terminal, or the like.

Optionally, the second communication device may be one or more of a terminal device and a radio access network device.

determining a second communication device capable of providing the sensing data satisfying the first request message based on the area information contained in the first request message and the location information of the second communication device; alternatively, the first and second electrodes may be,

and acquiring the equipment information of at least one second communication equipment meeting the area information based on the area information contained in the first request message, and determining the second communication equipment capable of providing the sensing data meeting the first request message according to the acquired equipment information.

Specifically, the sensing function entity determines the second communication device, and may determine, based on area information included in the first request message, such as information of a sensing area or a terminal identifier, the second communication device capable of providing sensing data satisfying the first request message according to location information of the second communication device, where the location information of the second communication device may be locally configured or acquired from another network function entity, such as a mobility management function entity, and is not limited herein; or, the sensing functional entity may also obtain, based on the area information included in the first request message, device information of at least one second communication device that satisfies the area information, and then determine, according to the obtained device information, a second communication device that can provide the sensing data that satisfies the first request message.

For example, taking the second communication device as the radio access network device as an example, if RAN node deployment information, such as location, topology, or identity, is configured in the awareness function entity, the awareness function entity may determine, according to the area information and the local configuration included in the first request message, a RAN node capable of providing awareness data satisfying the first request message.

Or, the sensing functional entity may also request, according to the area information included in the first request message, information of at least one RAN node that satisfies the area information from another network functional entity that stores RAN node information, and determine, according to the acquired RAN node information, a RAN node that can provide sensing data satisfying the first request message.

Optionally, acquiring device information of at least one second communication device that satisfies the area information based on the area information included in the first request message, includes:

and acquiring the equipment information of at least one second communication equipment meeting the area information from the network storage function entity or the mobility management function entity based on the area information contained in the first request message.

Specifically, the Network Function Entity such as a Network storage Function (NRF), a Unified Data Management Function (UDM), or a Mobility Management Function Entity (e.g., a Mobility Management Entity (MME) or an Access and Mobility Management Function (AMF)) may store information of various communication devices, and the sensing Function Entity may obtain, according to the area information included in the first request message, device information of at least one second communication device that satisfies the area information from the Network Function entities, so as to determine a second communication device that can provide the sensing Data that satisfies the first request message.

For example, the sensing function entity may request information of the RAN node from the NRF, where the request carries information such as an area or a terminal identifier, and the NRF returns the information of the RAN node to the sensing function entity based on the information.

For example, the sensing function entity may also request the UDM for information of the mobility management function entity, where the request carries information such as an area or a terminal identifier, and the UDM returns the information of the mobility management function entity to the sensing function entity based on the information. The sensing function entity then requests information of the RAN node serving the area or terminal from the mobility management function entity.

Optionally, if the second communication device is a radio access network device, acquiring the sensing data from the second communication device includes:

Specifically, since the sensing data amount is large, the sensing data needs to be transmitted through a plurality of control plane messages in transmission through the control plane, and the data transmission delay is increased. Therefore, in this embodiment of the present application, if the second communication device is a radio access network device, the sensing function entity may receive, through the user plane function entity, sensing data sent by the radio access network device.

For example, a data transmission path (e.g., N3 tunnel, connection, session, etc.) required for transmitting the sensing data may be established between a network RAN node and a User Plane Function (UPF), the RAN node transmits the sensing data through the path, and the UPF sends the data to the sensing Function in an IP routing manner.

sending a first connection establishment request to a mobility management function entity or a session management function entity, wherein the first connection establishment request is used for requesting to establish connection for transmitting sensing data by wireless access network equipment;

Specifically, in a scenario where the user plane functional entity receives the sensing data sent by the radio access network device, the sensing functional entity may first determine whether a connection related to sending the sensing data is already established, and if not, may send a first connection establishment request to the mobility management functional entity or the session management functional entity, where the first connection establishment request is used to request establishment of a connection for the radio access network device to transmit the sensing data, that is, the sensing functional entity may send a connection establishment request to the mobility management functional entity, and then the mobility management functional entity sends a connection establishment request to the session management functional entity, or the sensing functional entity may directly send a connection establishment request to the session management functional entity. The connection for the radio access network device to transmit the sensing data may refer to a data transmission path for transmitting data between the radio access network device and the user plane function, such as a PDU session or a PDN connection.

The first connection establishment request may carry one or more of the following information: connecting the identification; data Network Name (DNN); network Slice Selection Assistance Information (S-NSSAI); an identity of a sensory function entity; an Internet Protocol (IP) address of the awareness function entity; a port number of the sensing function entity; a Fully Qualified Domain Name (FQDN) of the sensing functional entity; location information of the perceptual functional entity; location information of the RAN node.

Optionally, the awareness function entity may select the mobility management function entity or the session management function entity based on the location information of the radio access network device and the location information of the awareness function entity before sending the first connection establishment request to the mobility management function entity or the session management function entity.

Fig. 2 is a second schematic flowchart of a perceptual data transmission method according to an embodiment of the present application, where the method is applied to a first network-side device, and as shown in fig. 2, the method includes the following steps:

200, receiving a sensing data acquisition request, wherein the sensing data acquisition request is used for requesting sensing data;

specifically, in this embodiment of the present application, the first network-side device may refer to any network-side device capable of requesting the sensing function entity to acquire sensing data, such as NEF, AMF, and the like, and when receiving a sensing data acquisition request (including an analysis request for analyzing sensing data), the first network-side device may determine to request the sensing function entity to acquire sensing data based on the sensing data acquisition request.

The sensing data acquisition request sent to the first network side device may be any communication device that needs to acquire sensing data, such as an application function entity, a terminal, or other network function entities, and when the communication device needs to acquire sensing data, the sensing data acquisition request may be sent to the first network side device, and the first network side device requests the sensing function entity for sensing data.

Step 201, determining a sensing function entity capable of providing sensing data based on a sensing data acquisition request, and sending a first request message to the determined sensing function entity;

specifically, after receiving the sensing data acquisition request, the first network side device may determine, according to the sensing data acquisition request, a sensing functional entity capable of providing sensing data, and send a first request message to the determined sensing functional entity.

After the sensing functional entity is determined, the first network side device can send a first request message to the determined sensing functional entity to request the sensing functional entity to provide sensing data.

The first request message may include attribute information of the perception data to be requested, such as one or more of data type information, region information, and time information. If the first network side device requests the sensing function entity to send the sensing data to other communication devices except the first network side device, the first request message may also carry information of the other devices.

Step 202, receiving the sensing data sent by the sensing functional entity.

Specifically, after the first network side device sends the first request message to the sensing function entity, the sensing function entity may determine corresponding sensing data according to the first request message, for example, the sensing data meeting the first request message may be determined from locally stored sensing data, or the sensing data meeting the first request message may be acquired from another device, such as a RAN node or a terminal.

After determining the sensing data meeting the first request message, the sensing functional entity transmits the sensing data to the first network side device, so that the first network side device can acquire the requested sensing data.

Optionally, the method further comprises:

Specifically, after receiving the sensing data sent by the sensing function entity, the first network side device may send the received sensing data to a communication device, such as an application function entity, a terminal, or other communication devices, that sends a sensing data acquisition request. For example, for a scenario in which the application function entity requests the sensing function entity for sensing data through the NEF, after receiving the sensing data sent by the sensing function entity, the NEF may send the sensing data to the application function entity.

Optionally, determining, based on the sensing data obtaining request, a sensing functional entity capable of providing sensing data, including:

determining a perception function entity capable of providing perception data according to a perception data acquisition request and the perception capability of the perception function entity; alternatively, the first and second electrodes may be,

and searching the sensing functional entity capable of providing the sensing data from the network storage functional entity according to the sensing data acquisition request.

Specifically, after receiving the sensing data acquisition request, the first network side device may determine, according to the sensing data acquisition request and the sensing capability of the sensing functional entity, a sensing functional entity capable of providing sensing data.

The sensing capability of the sensing function entity may refer to a service area, a supported sensing type, a supported sensing data reporting mode, and the like of the sensing function entity, and if the sensing function entity is located in a RAN node, the sensing capability may further include RAN node information where the sensing function entity is located. Therefore, the first network side device may determine the sensing functional entity capable of providing the sensing data according to the sensing capability of the sensing functional entity and the attribute information of the sensing data to be requested, which is included in the sensing data acquisition request.

For example, if the sensing data acquisition request carries information such as a sensing type, a sensing area, or an RAN node identifier, a sensing function entity matching the information may be screened out after the sensing capability of each terminal is queried.

After receiving the sensing data acquisition request, the first network side device may also search, according to the sensing data acquisition request, a sensing function entity capable of providing sensing data from the network storage function entity.

Specifically, in order to support other network elements to select the sensing functional entity, the sensing functional entity may register its own sensing capability information in the network storage functional entity, so that the other network elements may select the sensing functional entity by searching the network storage functional entity. The sensing capability information of the sensing function entity may include a service area and a capability (for example, a supported sensing type and a supported sensing data reporting mode, and if the sensing reporting mode is user plane reporting, IP address and/or port number information of the sensing function entity may also be provided).

Specifically, after the sensing capability information of the sensing functional entity can be registered in the network storage functional entity, other network elements, such as the first network side device, can send a query request to the network storage functional entity, and parameters such as the sensing type, the sensing area, the radio access network device identifier, and the like are carried in the request message, so that the network storage functional entity can reply the information of the sensing functional entity corresponding to the parameters to the first network side device.

Optionally, if the first request message includes address information of the first network-side device, the receiving of the sensing data sent by the sensing functional entity includes:

Specifically, since the sensing data amount is large, the sensing data is transmitted through the control plane, and multiple control plane messages are required to transmit the sensing data, so that the data transmission delay is increased. Therefore, in this embodiment of the present application, the first network-side device may carry address information of the first network-side device in the first request message sent to the sensing function entity, so that the sensing function entity may transmit sensing data to the first network-side device through the user plane function entity according to the address information. The address information of the first network side device may be information such as an IP address, a port number, or an FQDN of the first network side device.

In this embodiment of the present application, the triggering of the connection establishment request may be determined after the mobility management functional entity receives the sensing confirmation information sent by the radio access network device, or determined after the mobility management functional entity receives the connection establishment request sent by the sensing functional entity or the radio access network device, that is, the sensing functional entity may first trigger a connection establishment procedure and then send the connection establishment request to the mobility management functional entity, or may be that the radio access network device first triggers the connection establishment procedure and then sends the connection establishment request to the mobility management functional entity. Then the mobile management function entity sends a second connection establishment request to the session management function entity, and after receiving the second connection establishment request, the session management function entity can execute a connection establishment process based on the second connection establishment request and the user plane function entity, and establish a connection for the radio access network equipment to transmit the sensing data.

and determining the session management function entity based on the position information of the wireless access network equipment and the position information of the perception function entity.

Specifically, the mobility management function entity may select the session management function entity based on the location information of the radio access network device and the location information of the awareness function entity before sending the second connection establishment request to the session management function entity.

Specifically, in order to establish a connection for transmitting sensing data by the radio access network device, in this embodiment of the present application, the mobility management functional entity may send a connection establishment request to the session management functional entity, or the sensing functional entity may directly send a connection establishment request to the session management functional entity, and after receiving the connection establishment request, the session management functional entity may execute a connection establishment procedure with the user plane functional entity based on the connection establishment request. The process may be an N4 session establishment process or other connection establishment process, where the process allocates tunnel endpoint information of a tunnel for transmitting the sensing data to the user plane functional entity, and then the session management functional entity may send the tunnel endpoint information allocated to the user plane functional entity to the radio access network device.

Optionally, the third connection establishment request may carry one or more of the following items of information: connecting the identification; DNN; S-NSSAI; an identity of a sensory function entity; an IP address of the sensing function entity; a port number of the sensing function entity; FQDN of the perception function entity; location information of the sensing functional entity; location information of the RAN node.

The AMF selects the sensing function entity according to the parameters in the request. In this embodiment, only the sensing function entity on the RAN node to which the UE is connected needs to collect data.

Step 1301, the AMF sends an N2 sensing data request message to the RAN node, and the message carries a sensing area or UE NGAP ID.

The sensing data volume is large, the sensing data is transmitted through the control plane, and a plurality of control plane messages are needed to transmit the sensing data, so that the data transmission time delay is increased. In this embodiment, the perception data is transmitted through the user plane. A data transmission path (such as an N3 tunnel, a connection, a session and the like) required for transmitting the sensing data is established between a network RAN node and a UPF, the RAN node transmits the sensing data through the path, the UPF transmits the data to a sensing function entity in an IP routing mode, and the sensing function entity transmits the data to an AF in the IP routing mode. The specific process is as follows:

2) By NRF: the sensing function entity sends UE ID or area to NRF, and NRF returns RAN node information to the sensing function entity.

3) By UDM:

Otherwise, step 1507 is performed. RAN node sends session establishment request to mobile management function, the message carries connection identification, DNN, S-NSSAI, ID or FQDN of perception function entity, etc. The RAN node is preconfigured with DNN and S-NSSAI required for sending sensing data, and if not, is not provided.

Step 1511, a connection establishment procedure is performed between the session management function and the user plane function, and the procedure may be an N4 session establishment procedure or a connection establishment procedure. The process assigns tunnel endpoint information for the tunnel that transports the perception data to the user plane function.

Step 1512, the session management function sends a session establishment reply to the mobility management function, where the message includes session management information, context identifier, and connection identifier. The session management information includes parameters such as tunnel endpoint information and QoS of the user plane function.

Step 1513, the mobility management function sends a session setup reply to the RAN, the message including session management information.

Step 1514, the RAN node allocates tunnel endpoint information and then sends a session modification request to the mobility management function, the message including connection identification, session management information. After this step, the RAN node may send the sensing data to the sensing function entity, and the sensing function entity sends the sensing data to the AF.

Step 1515, the mobility management function sends a session modification request to the session management function, where the message includes a connection identifier/context identifier and session management information. The session management information includes tunnel endpoint identification of the RAN node.

Step 1516, the session management function initiates a connection modification procedure to the user plane function, and sends the tunnel endpoint identifier of the RAN node to the user plane function.

Step 1517, the session management function sends a session modification reply message to the mobility management function.

Description of the above steps 1503-1505:

if there is no direct interface between the sensing function entity and the RAN node, steps 1503-1505 should be performed as follows (not shown in fig. 15):

step 1518, the sensing function entity selects the mobility management function, and the selection mode may be NRF selection, UDM selection, selection according to local configuration, and the like.

And step 1519, the sensing function entity sends the sensing request to the selected mobility management function.

Example eleven:

fig. 16 is a twelfth schematic signaling interaction diagram of a method for sensing data transmission provided in the embodiment of the present application, and as shown in fig. 16, a difference from the tenth embodiment is that in the present embodiment, a mobility management function triggers establishment of a user plane connection. The specific process is as follows:

step 1600, the AF sends a sensing request to the network open function, where the message carries Quality of Service (QoS), a sensing data reporting mode (e.g., periodic reporting, event-based reporting, or threshold-based reporting), a UE ID (for collecting sensing data of a specific UE) or an area (for collecting sensing data in the area), a sensing type, an FQDN of the AF, an IP address and port number, an association Identifier (Identifier, ID), and the like.

Otherwise steps 1609-1618 are skipped. For each RAN node for which a transmission path is not established, the AMF selects an SMF according to the location of the RAN node, the location of the sensing function entity, and the like.

Steps 1610 to 1618, and steps 1509 to 1517 as in the tenth embodiment.

In order to solve the problem, in this embodiment, one or more aggregation RAN nodes are selected from the plurality of RAN nodes, and the aggregation RAN node is responsible for collecting sensing data from other non-aggregation RAN nodes, and then sends all the collected sensing data to the sensing function entity, so that it is only necessary to establish a data transmission path between the aggregation RAN node and the sensing function entity, and establish a data transmission path between the aggregation RAN node and the non-aggregation RAN node.

Fig. 17 is a schematic diagram of signaling interaction of the method for sensing data transmission according to the embodiment of the present application, where as shown in fig. 17, the AMF triggers the establishment of a direct forwarding path between the non-aggregation RAN node and the aggregation RAN node. The specific process is as follows:

step 1700, the AMF sends a direct forwarding request to the non-aggregation RAN node, where the message carries the association ID, the FQDN, the IP address, and the port number of the sensing function entity, and the aggregation RAN node identifier.

Step 1701 establishes a direct forwarding tunnel between the non-aggregating RAN node and the aggregating RAN node.

Step 1702, the non-aggregating RAN node sends a direct forwarding acknowledgement to the AMF. After this operation, the non-aggregating RAN node may send the awareness data to the aggregating RAN node.

Besides the implementation mode, the AMF can also send a direct forwarding request to the aggregation RAN node, the message carries the identification of the non-aggregation RAN node, the association ID, the FQDN, the IP address, the port number and the like of the sensing function entity, the aggregation RAN node triggers the establishment process of a direct forwarding path to the non-aggregation RAN node, and the AMF sends a confirmation message after the establishment is completed.

In the above scenario, a sensing functional entity or a mobility management functional entity may send a first sensing request to an aggregation RAN node, where the first sensing request carries information of a non-aggregation RAN node (such as RAN node identifier, IP address, port number, FQDN, and other information), and the sensing request is used to instruct the aggregation RAN node to obtain sensing data from the non-aggregation RAN node; and/or the presence of a gas in the gas,

This information may be relayed through other core network functions, such as AMF, sensing function entities, etc.

Step 1810, the RAN node sends session management information, including tunnel endpoint information of the RAN node, to the session management function. This information may be relayed through other core network functions, such as AMF, sensing function entities, etc. After this step, the RAN node may send the sensing data to the sensing function entity, which sends the sensing data to the AF.

Step 1811, the session management function initiates a connection modification process to the user plane function, and sends the tunnel endpoint identifier of the RAN node to the user plane function.
