Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, combination of 5G and 5G, combination of 5G and 6G, and the like).

[0136] Wireless sensing technologies aim to detect and / or acquire characteristics of physical objects at a distance without physical contact. The sensing data of objects and their environment data can be used for analysis, so that the effective characteristics and / or effective information of objects can be extracted.

[0137] In some embodiments, integrated sensing and communication means that the sensing capability is provided by the same wireless communication system and base station facilities used for communication, and the sensing information can be obtained from Radio Frequency (RF) or non-RF based sensors. In general, it can involve scenarios of communication-assisted sensing; for example, a 5G communication system provides sensing services or sensing services assist communication; for another example, sensing information related to communication channels or environments is used to improve communication services; for another example, sensing information can be used to assist radio resource management, interference mitigation, beam management and / or mobility, etc.

[0138] In some embodiments, some examples of communication-assisted sensing services are provided:

[0139] Example 1: Real-time environmental monitoring. Real-time environmental monitoring can use wireless signals to reconstruct an environmental map to further improve positioning accuracy and implement environment-related applications. For example, the real-time monitoring-related applications can include dynamic 3D maps for driving assistance, pedestrian flow statistics, intrusion detection and / or traffic detection, etc.

[0140] Example 2: Autonomous vehicles / drones. Autonomous vehicles / drones have some common functional requirements. For example, autonomous vehicles / drones should support detect and avoid (DAA) to avoid obstacles. Optionally, autonomous vehicles / drones should have the ability to monitor path information, such as route selection and / or compliance with traffic regulations, etc.

[0141] Example 3: Air pollution monitoring. With changes in air humidity, air particulate matter (PM) concentration and / or carrier frequency, etc., the quality of received wireless signals shows different attenuation characteristics, which can be used for weather or air quality detection.

[0142] Example 4: Indoor health care and intrusion detection. Indoor health care and intrusion detection can implement breathing rate estimation, breathing depth estimation, apnea detection, elderly vital sign monitoring and / or indoor intrusion detection, etc.

[0143] In some embodiments, a wireless access network node (e.g., an access network device) can act as a receiver to collect 3GPP sensing data, and a large amount of sensing data should be sent to the core network.

[0144] In other services, such as Artificial Intelligence (AI) services, a large amount of service data needs to be exchanged between the access network and the core network for data processing. Here, the data is not for each UE but for a group of UEs, or not for the UE but for the object; and the data can be used for data services from any consumer, such as data services from the UE, the Application Server (AS), the RAN node (such as the access network device), or the core network network function (NF). Therefore, the connection between the access network and the core network should be managed to exchange a large amount of service data.

[0145] In some embodiments, a User Plane path is established between the UE and the Data Network (DN) using a Protocol Data Unit (PDU) session management mechanism; the PDU session management mechanism can be UE-(R)AN node (such as an access network device)-UPS-AS. The PDU session management mechanism mainly includes the following: PDU session establishment; PDU session modification; PDU session release.

[0146] The PDU session establishment is initiated by the UE using a Non Access Stratum (NAS) message, and in the core network, the session management is implemented by the Session Management Function (SMF).

[0147] Using the current UP path of the PDU session to transmit the PDU, the base station (such as gNB) only forwards the PDU sent from the UE to the UPF, and the UPF forwards the PDU to the application server identified by the destination address of the PDU. However, there is no solution for transmitting a large amount of service data from the service-oriented (R)AN, which is generated by the (R)AN and sent to the related core network function.

[0148] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0149] Figure 2A is an interaction diagram of an information processing method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiment of the present disclosure relates to an information processing method for an information processing system 100, and the above method comprises:

[0150] Step S2101, the first network function determines to establish a connection for data transmission between the access network device and the second network device. Optionally, the first network function selects the second network function.

[0151] In some embodiments, the first network function can be any network function with data traffic connection management capability, such as a network element or entity or network function with network analytics and / or data traffic management and its corresponding data traffic connection management capability, etc. For example, the first network function is one of the following: DSTMF, NWDAF, DPMF, LMF, SF, and SMF.

[0152] In some embodiments, the second network function can be any network element or entity with data processing or data plane data processing capability; for example, the second network function is a DPF.

[0153] In some embodiments, the second network function is an end node of the connection; the second network function is used to process data. The access network device and the second network function are end-to-end end nodes of the connection.

[0154] In some embodiments, the third network function can be any network element or entity or network function with data forwarding capability, etc. For example, the third network function is a UPF.

[0155] In some embodiments, the third network function is an intermediate node of the connection; the third network function is used to forward data.

[0156] Optionally, the connection can be a connection between the access network device and the second network function. For example, the transmission path of the connection can be associated with the third network function or not associated with the third network function; for example, the transmission path of the connection can be from the access network device to the second network function; for example, the transmission path of the connection can be from the access network device to the third network function and then to the second network function. In the case of the transmission path of the connection associated with the third network function, there can be one or more third network functions; in the case of multiple third network functions, one of the third network functions is directly connected to the access network device, and the other third network functions are intermediate nodes of the third network function and the second network function.

[0157] Optionally, the connection can be a non-UE connection. For example, the non-UE connection is used to transmit data of at least one service. The non-UE connection is not data transmission for a certain UE, but can be data transmission for a group of UEs or data transmission for a service, etc.

[0158] For example, in the case of the transmission path of the connection associated with the third network function, the data of the connection is sent by the access network device to the second network function through the third network function. For example, uplink data can be sent by the access network device to the third network function, and then sent by the third network function to the second network function; and / or, downlink data can be sent by the second network function to the third network function, and then forwarded by the third network function to the access network device.

[0159] For example, the connected data can be uplink data transmitted by the access network device to the second network function, and / or downlink data transmitted by the second network function to the access network device.

[0160] Optionally, the data can be data of any service or user plane data or data of the first service. For example, the first service can be a specified service or a pre-set service. For example, the first service includes at least one of the following: a defined service, a sensing service, and an intelligent service. For example, the intelligent service can be an AI service, etc.

[0161] Optionally, the connection between the access network device and the second network function can be shared by data services requiring data exchange between the access network device and the second network function, or the connection can be dedicated to a specific data service. Sharing of multiple connections between the access network device and the second network function can be determined based on data traffic or any data flow between the access network device and the second network function, or service type or service type data of the data flow.

[0162] For example, the connection dedicated to the specific data service can mean that a corresponding connection is triggered to be established for each data service task requiring data from the determined access network device, i.e., the data service task and the connection are in a one-to-one relationship.

[0163] For example, the connection dedicated to the specific data service can mean that a connection dedicated to each service or task can be established, and a connection dedicated to each type of service can be established.

[0164] For example, the connection can be shared according to the data service type, i.e., data service tasks of the same service type obtaining data from the determined access network device share a connection. When a connection is triggered to be established for the same type of service type, the data service of the same type of service type does not need to establish a new connection, and can reuse the existing connection for data transmission, which can involve connection modification to ensure data transmission to the specified network function.

[0165] For example, the connection can be shared according to the node granularity, i.e., data service tasks of all service types obtaining data from the determined access network device share a connection.

[0166] For example, the connection can be shared according to one or more specified service types, i.e., the specified one or more services can share the connection.

[0167] Exemplarily, the connections can be shared according to a specified number of service flows, i.e., data corresponding to the specified number of service flows shares the connections established for the specified number of service flows.

[0168] Exemplarily, the connections can be shared according to a specified type of service flow, i.e., data corresponding to the specified type of service flow shares the connections established for the specified type of service flow.

[0169] In some optional embodiments, the first network function acquires the second information or queries the second network function meeting the conditions with the second information as input conditions.

[0170] Optionally, the second information can include at least one of the following: information of an access network device, first capability information, and / or first load information.

[0171] Exemplarily, the information of the access network device is used to indicate a list of tracking area identities (TAIs) and / or a list of cell identities (CIs) supported by the access network device, or the information of the access network device includes the list of TAIs and / or the list of CIs. The list of TAIs includes at least one TAI, and one TAI is used to identify an area; the list of CIs includes at least one CI, and one CI is used to identify a cell.

[0172] Exemplarily, the information of the access network device can be used to indicate the access network device; for example, the information of the access network device can include an indication of an access network device identifier, etc.

[0173] Exemplarily, the name of the information of the access network device is not limited; for example, it is node information or (RAN) node information.

[0174] Exemplarily, the first capability information can be used to indicate whether the capability of the connection is supported. For example, the first capability information is used to indicate whether the second network function supports the capability required for the connection. For example, the capability required for the connection supporting the transmission of data corresponding to the service can include the capability of encapsulating and sending data corresponding to the transmission protocol.

[0175] Exemplarily, the first capability information can be used to indicate whether the capability required for the supported service is supported; the capability required for the service can be the capability of transmitting and / or processing data corresponding to any service. For example, for a positioning service, the first capability information is used to indicate whether the capability of transmitting and / or processing data related to the positioning service is supported; for example, for a sensing service, the first capability information is used to indicate whether the capability of transmitting and / or processing data related to the sensing service is supported; and the like. For example, the first capability information is used to indicate whether the second network function supports the capability required for the service.

[0176] Exemplarily, the first capability information can be used to indicate a capability supported by the second network function for the service type. For example, the first capability information indicates a capability supported by the second network function for transmitting data of a positioning service and / or a capability supported by the second network function for transmitting data of a sensing service.

[0177] Exemplarily, the first load information is used to indicate a load status of the second network function.

[0178] Optionally, the first network function receives information of the access network device sent by a terminal or an Application Function (AF) or a 5GC Network Function (NF), etc. Exemplarily, the first network function receives a service request sent by a terminal or an AF or a 5GC NF, and the service request includes the information of the access network device. Exemplarily, the service request is used to request collecting of service data.

[0179] An implementation manner: the service request can further include third capability information and / or third load information; the third capability information is used to indicate a capability required by the service; the third capability information can be explicitly included in the service request or can be derived by a service type and / or a service related parameter of the service request; the third load information is used to indicate a load required by the service.

[0180] Another implementation manner: the first capability information can indicate a capability supported by the second network function and / or a capability required by the service; and / or, the first load information can indicate a load supported by the second network function and / or a load required by the service.

[0181] Optionally, the first network function acquires the stored second information.

[0182] Optionally, a name of the second information is not limited; for example, it is (R)AN node information or capability indication information or load indication information, etc.

[0183] In some embodiments, the first network function determines the second network function based on the second information.

[0184] In some embodiments, the first network function determines the second network function based on an area and / or a location of the service data requested.

[0185] Optionally, the first network function determines the second network function based on an area and / or a location of the service data requested, in a case that the information of the access network device is not acquired.

[0186] Optionally, the first network function can determine the second network function based on the second information and the third capability information and / or the third load information.

[0187] For example, the first network function determines the capability required by the service as the first capability based on the third capability information; the first network function determines that there are three second network functions based on the information of the access network device, wherein the first second network function has the first capability required by the service, and the second and third second network functions do not have the first capability required by the service; then the first network function selects the first second network function as the end node of the connection, that is, the first network function selects the first second network function.

[0188] For example, the first network function determines three second network functions based on information from the access network device, wherein the second second network function has a smaller load than the first and third second network functions; then the first network function selects the second second network function as the end node for connection, that is, the first network function selects the second second network function.

[0189] For example, if the first network function determines that it has not obtained information from the access network device, it may determine any second network function in the area and / or location where the requested service data is located as the desired second network function; or determine a second network function in the area and / or location that meets the service requirements as the desired second network function; or determine a second network function in the area and / or location with the lowest load as the desired second network function (i.e., as the end node of the connection).

[0190] For example, when the first network function selects the second network function, it may not consider the information of the access network device or the region and / or location of the requested service data.

[0191] Optionally, some of the conditions and combinations for selecting a second network function as described above may also be used. Selecting a second network function involves choosing one that meets the conditions from a list containing at least one second network function.

[0192] In some alternative embodiments, when a first network function determines that a service needs to obtain data from an access network device, it determines that a data transmission channel needs to be established, with the access network device being one end node of the connection; it then determines that a second network function receiving the data is the other end node of the connection and begins establishing a connection between the two end nodes. That is, the first network device determines that a connection needs to be established between the access network device and the second network function.

[0193] In some alternative embodiments, the first network function requests the data connection required to establish a connection with the DPF.

[0194] In step S2102, the first network function sends third information to the second network function.

[0195] In some embodiments, the second network function receives third information sent by the first network function.

[0196] In some embodiments, the first network function sends third information to the second network function when no connection is established between the access network device and the second network function.

[0197] In some embodiments, the third information includes a first identifier, and the third information is used to establish a connection between the access network device and the third network function, and to set the third network function as the end node of the transmission path of the connection between the access network device and the third network function.

[0198] Optionally, the first identifier is used to indicate the connection between the access network device and the second network function.

[0199] Optionally, the name of the third information is not limited; it may be, for example, a data connection establishment request or message.

[0200] In some alternative embodiments, the second network function is able to send a second response to the first network.

[0201] In some alternative embodiments, the first network function receives a second response sent by the second network function.

[0202] Optionally, the second response is determined based on third information.

[0203] Optionally, the second response is used to confirm the establishment of a connection. For example, the second response is used to confirm the establishment of a connection between the access network device and the second network function. For example, the second response is used to confirm that the established connection requires connection to the second network function.

[0204] Optionally, the name of the second response is not limited; for example, it may be a data connection establishment response, etc.

[0205] In some alternative embodiments, the first network function performs the first operation.

[0206] Optionally, the first operation includes at least one of the following: determining a first identifier for the connection; determining the use of the connection to provide services; determining address information for a second network function of the connection; and storing seventh information related to the connection.

[0207] Optionally, if no connection is established between the access network device and the second network function, the first network function determines a first identifier for the connection. For example, the first network function assigns an identifier for the connection. Here, the operation of determining the first identifier for the connection is performed before step S2102.

[0208] Optionally, the first network function provides services using the connection when a connection is established between the access network device and the second network function.

[0209] Optionally, the first network function determines the address information of the second network function used for connection.

[0210] For example, the first network function determines the address information of the second network function for connection based on the second information, or the first network function selects one address from at least one address of the second network function as the address information of the second network function for connection.

[0211] For example, a second network function can correspond to one or more address information. Different services can correspond to different connections, and the address information of the second network function can be different for different connections.

[0212] Optionally, the first network function assigns address information for the second network function to be connected.

[0213] Optionally, the first network function stores seventh information. For example, the seventh information includes at least one of the following: a first identifier, first address information, and / or transmission information indicating the transmission protocol corresponding to the connection. For example, the first address information includes address information of the second network function associated with the transmission path of the connection. For example, the first address information includes address information of the second network function associated with the transmission path of the connection and address information of the third network function.

[0214] Optionally, the name of the seventh piece of information is not limited; it may be, for example, related information or linking related information.

[0215] In some alternative embodiments, the second network function performs the second operation.

[0216] Optionally, the second operation includes at least one of the following: allocating address information for the second network function; and storing seventh information related to the connection.

[0217] Optionally, the second network function assigns address information for the second network function used for connection.

[0218] Optionally, the second network function stores seventh information. For example, the seventh information includes at least one of the following: a first identifier, first address information, and / or transmission information indicating the transmission protocol corresponding to the connection. For example, the first address information includes address information of the second network function associated with the connection. For example, the first address information includes address information of the second network function associated with the connection and address information of the third network function associated with the connection.

[0219] Step S2103: The first network function determines the third network function. Optionally, the first network function selects the third network function.

[0220] In some embodiments, the first network function determines the third network function based on the second information. Optionally, the second information may include at least one of the following: information about the access network device, second capability information, and / or second load information.

[0221] For example, the second capability information can be used to indicate whether a connection capability is supported. For instance, the second capability information can be used to indicate whether a third network function supports a connection capability. For example, the connection capability required to support the data transmission of a corresponding service may include the capability to encapsulate and forward data via a corresponding transport protocol.

[0222] For example, the second capability information can be used to indicate whether the capabilities required for a service are supported; these capabilities can refer to the ability to transmit and / or process data corresponding to any service. For instance, for a location service, the second capability information indicates whether the capabilities for data transmission and / or data processing related to the location service are supported; similarly, for a sensing service, the second capability information indicates whether the capabilities for data transmission and / or data processing related to the sensing service are supported; and so on. For example, the second capability information can indicate whether a third network function supports the capabilities required for the service.

[0223] For example, the second capability information can be used to indicate the capability of a third network function to support certain service types. For instance, the second capability information indicates the capability of a third network function to support the transmission of data for location services and / or the capability to support the transmission of data for sensing services.

[0224] For example, the second load information is used to indicate the load status of the third network function.

[0225] One implementation: The service request may further include third capability information and / or third load information; the third capability information is used to indicate the capabilities required by the service, and the third capability information may be displayed in the service request or may be derived from the service type and / or service-related parameters of the service request; the third load information is used to indicate the load required by the service.

[0226] Another implementation: the second capability information may indicate the capabilities supported by the third network function and / or the capabilities required by the service; and / or, the second load information may indicate the load supported by the third network function and / or the load required by the service.

[0227] In some embodiments, the first network function determines the third network function based on the address information of the second network function. That is, it selects a relay node or intermediate node for the optimized transmission path of the third network to be connected.

[0228] In some embodiments, the first network function determines the third network function based on the region and / or location of the requested service data.

[0229] Optionally, if the first network function determines that it has not obtained information about the access network device, it may determine a third network function based on the region and / or location of the requested service data.

[0230] Optionally, the first network function may determine the third network function based on the second information, the third capability information, and / or the third load information.

[0231] For example, the first network function determines the capability required for the service as the first capability based on the third capability information; the first network function determines that there are three third network functions based on the information of the access network device, wherein the first third network function has the first capability required for the service, and the second and third third network functions do not have the first capability required for the service; then the first network function selects the first third network function as the end node for connection, that is, the first network function selects the first third network function.

[0232] For example, the first network function determines three third network functions based on information from the access network device, wherein the second third network function has a smaller load than the first and third third network functions; then the first network function selects the second third network function as the end node for connection, that is, the first network function selects the second third network function.

[0233] For example, if the first network function determines that it has not obtained information from the access network device, it may determine any third network function in the area and / or location where the requested service data is located as the required third network function; or determine a third network function in the area and / or location that meets the service requirements as the required third network function; or determine a third network function in the area and / or location with the lowest load as the required third network function (i.e., as an intermediate node for the connection).

[0234] Optionally, the first network function can select multiple third network functions, one of which is directly connected to the access network device, while the other third network functions serve as intermediate nodes between the selected third network function and the second network function. The conditions and combinations for selecting the second network function described above can also be partially used. Selecting a third network function involves choosing a suitable third network function from a list containing at least one third network function. When selecting a third network function that is directly connected to the access network device, the first network function must select a third network function that can establish a connection to the access network device.

[0235] Step S2104: The first network function sends the fourth information to the third network function.

[0236] In some embodiments, the third network function receives fourth information sent by the first network function.

[0237] In some embodiments, if the third network function determines that there is no connection between the access network device and the second network function that can be used to connect the access network device and the second network function, the third network function sends fourth information to the third network function.

[0238] In some embodiments, the third network function serves as an intermediate node connecting the access network device and the second network function. The connection between the access network device and the second network function can be a complete end-to-end connection, or it can be a combination of the connection between the access network device and the third network function plus the connection between the third network function and the second network function.

[0239] In some embodiments, the fourth information includes a first identifier, which is used to establish a connection between the access network device and the second network function, and to set the third network function as an intermediate node in the transmission path of the connection between the access network device and the second network function.

[0244] Optionally, the third response is determined based on the fourth information.

[0245] Optionally, the third response is used to confirm the establishment of the connection. For example, the third response is used to confirm the establishment of a connection between the access network device and the second network function. For example, the third response is used to confirm that the established connection requires the connection's transmission path to be associated with the third network function.

[0246] Optionally, the name of the third response is not limited; for example, it may be a data connection establishment response, etc.

[0247] In some alternative embodiments, the first network function determines address information for a third network function to be connected. Optionally, the first operation may further include: determining the address information of the third network function to be connected.

[0248] Optionally, the first network function determines the address information of the third network function for connection. For example, the first network function determines the address information of the third network function for connection based on second information, or the first network function selects one address from the address information of at least one third network function as the address information of the third network function for connection.

[0249] For example, a third network function can correspond to one or more address information. Different services can correspond to different connections, and the address information of the third network function can be different for different connections.

[0250] Optionally, the first network function assigns address information for the third network function to be connected.

[0251] In some alternative embodiments, the third network function performs a third operation.

[0252] Optionally, the third operation includes at least one of the following: allocating address information for the third network function; and storing seventh information related to the connection.

[0253] Optionally, the third network function assigns address information for the third network function used for connection.

[0254] Optionally, the third network function stores seventh information. For example, the seventh information includes at least one of the following: a first identifier, first address information, and / or transmission information indicating the transmission protocol corresponding to the connection. For example, the first address information includes address information from the second network function and address information from the third network function.

[0255] Step S2105: The first network function sends the first information to the access network device.

[0256] In some embodiments, the access network device receives first information sent by a first network function.

[0257] In some embodiments, the first information includes a first identifier and first address information.

[0258] In some embodiments, the first information is used to request the establishment of a connection.

[0259] Optionally, the first address information is used to indicate the network function associated with the transmission path of the connection.

[0260] For example, when the first address information includes the address information of the second network function, the connected transmission path is associated with the second network function but not with the third network function.

[0261] For example, when the first address information includes the address information of the second network function and the address information of the third network function, the connected transmission path is associated with the second network function and the third network function.

[0262] Optionally, the name of the first address information is not limited, and it may be, for example, core network (CN) address information.

[0263] Optionally, the first information may include transmission information, which is used to indicate the transmission protocol corresponding to the connection, or to indicate the transmission protocol used by the connection.

[0264] For example, transmission information can be used to indicate the transmission protocol corresponding to each segment in the connection. For instance, transmission information can indicate that the connection between the access network device and the third network function corresponds to a first transmission protocol; or, transmission information can indicate that the connection between the third network function and the second network function corresponds to a second transmission protocol; or, transmission information can indicate that the connection between the access network device and the second network function corresponds to a third transmission protocol. For example, data transmitted between the access network device and the third network function may use the first transmission protocol, and data transmitted between the third network function and the second network function may use the second transmission protocol.

[0265] For example, when the transmission information is a first value, it indicates that the connection between the access network device and the third network function corresponds to the General Packet Radio System (GPRS) Tunneling Protocol-User Plane (GTP-U); or, when the transmission information is a second value, it indicates that the connection between the access network device and the second network function corresponds to the Quick UDP Internet Connection (QUIC) based on UDP; or, when the transmission information is a third value, it indicates that the connection between the access network device and the third network function directly uses the TCP / IP protocol or the IP protocol for transmission. The transmission information can be a list of values, such as multiple transmission protocol selections; or, when specifying transmission protocols for segmented connections, it can correspond to the transmission protocols for each segment path or a list of transmission protocol selections for each segment path.

[0266] Optionally, the first information may include connection indication information, wherein the connection indication information is used to indicate the type of connection, and the type of connection is used to indicate the transport protocol corresponding to the connection.

[0267] Optionally, the transport protocol corresponding to the connection is indicated based on the type of connection.

[0268] For example, different connection types can be used to indicate different transport protocols, or different connection types can correspond to different transport protocols.

[0269] For example, the connection type may include a first type or a second type. For instance, a first type connection is a transmission path for non-terminal related data; a second type connection is a transmission path for terminal related data.

[0270] For example, the type of connection can be determined based on the service data transmitted by the connection. For instance, the first type of connection is a connection for transmitting location service data; the second type of connection is a connection for transmitting sensing service data; and the third type of connection is a connection for transmitting intelligent services.

[0271] For example, a connection of type 1 indicates that the connection corresponds to a first transport protocol; a connection of type 2 indicates that the connection corresponds to a second transport protocol; and a connection of type 3 indicates that the connection corresponds to a third transport protocol. Multiple connection types may share the same transport protocol by agreement.

[0272] Optionally, the transport protocol corresponding to the connection is indicated by the network function associated with the transport path of the connection.

[0273] For example, when the second network function of the end node associated with the connected transmission path is used for non-terminal related data transmission (collection) and processing, it is used to indicate that the connection to the second network function corresponds to the first transmission protocol; or when the third network function of the end node associated with the connected transmission path is used for locating service related data transmission (collection) and processing, it is used to indicate that the connection to the second network function corresponds to the second transmission protocol.

[0274] Optionally, the corresponding transport protocol for the connection is based on the first address information.

[0275] For example, the first address information includes address information of the second network function and address information of the third network function, used to indicate the connection corresponding to the first transmission protocol; or, the first address information includes address information of the second network function, used to indicate the connection corresponding to the second transmission protocol.

[0276] For example, the first address information may also include an identifier indicating a transmission protocol. For instance, the first address information may include address information for a third network function and a GTP-U tunnel identifier (ID), used to indicate that the connection between the access network device and the third network function uses or corresponds to GTP-U. As another example, the first address information may include address information for a second network function and an identifier indicating a QUIC, used to indicate that the connection between the access network device and the second network function uses or corresponds to a QUIC.

[0277] Optionally, the name of the first message is not limited; it may be, for example, a connection establishment request or message, or a call to a specified service.

For example, when the access network device determines that a connection has been established between the access network device and the second network function, it sends a first response to the first network function to confirm or indicate that a connection has been established between the access network device and the second network function. For example, the first response may include first indication information, which indicates that a connection has been established between the access network device and the second network function.

[0282] Optionally, the first response can also be used to indicate that a connection has not been established. For example, if the access network device determines that a connection has not been established between the access network device and the second network function, it sends a first response to the first network function, the first response indicating that a connection has not been established between the access network device and the second network function. For example, the first response may include second indication information indicating that a connection has not been established between the access network device and the second network function.

[0283] Optionally, the first response may include second address information.

[0284] For example, the second address information is the address information of the access network device associated with the connected transmission path.

[0550] In some embodiments, the above methods may include the methods described in the above-described information processing system side, first network function side, access network device side, second network function side and / or third network function side embodiments, which will not be repeated here.

[0551] This disclosure provides a method for transmitting service-oriented (R)AN service data to core network functions via a connection between (R)AN and CN; the method includes the following:

[0552] DSTMF acquires information for establishing a connection between (R)AN nodes and core network functions; this connection can be shared by any data service that needs to exchange data between access network equipment and core network functions, or it can be dedicated to a specific data service.

[0553] DSTMF manages the connection between (R)AN nodes and core network functions. Optionally, DSTMF directly sends requests for establishing a connection between the (R)AN node's address information and the core network function to the (R)AN node. Optionally, DSTMF configures rules for the UPF and / or DPF to process data packets exchanged between the (R)AN node and the core network node. Optionally, DSTMF can modify or release connections.

[0554] (R)AN establishes a connection and sends the (R)AN node address information to DSTMF.

[0555] Data is exchanged using the indicated transport protocol via a connection between the (R)AN and core network functions.

[0556] Optionally, the (R)AN node can be the access network device in the previous embodiment; the (R)AN node address information can be the second address information in the previous embodiment; and the core network function can be the second network function and / or the third network function in the previous embodiment.

[0557] Example 1: Establishing a connection between (R)AN and core network functions, including UPF.

[0558] In this embodiment, it is assumed that the connection for the (R)AN node and core network (CN) functions is managed by the DSTMF, and the core network function receiving data from the (R)AN node is the DPF. The transmission path from the (R)AN node to the DPF involves the UPF. The DSTMF can be deployed together with the SMF or as an enhanced SMF, and the DPF can be a dedicated UPF supporting data processing for data services. Figure 8A shows a schematic diagram of the relevant network functions. The data transmission path between the (R)AN and core network functions is forwarded through the UPF, and the N3 interface between the (R)AN and CN can be reused as much as possible. The DSTMF can be a general network function for all data services processed in the CN, or it can be part of any specific network function for a specific data service, such as the LMF, SF, or NWDAF. This embodiment focuses only on connection management functions; other functions for data services can be configured together with the DSTMF and / or DPF, or independently of the DSTMF and / or DPF.

[0559] The connection between the (R)AN node and the DPF can be shared by data services that require data exchange between the (R)AN node and the DPF node, or it can be dedicated to a specific data service.

[0560] Figure 8B is a flowchart illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 8B, the present disclosure relates to an information processing method, which includes:

[0561] In step S8101, DSTMF selects DPF and determines that a connection needs to be established between the (R)AN node and the DPF.

[0562] Optionally, the DSTMF acquires service requests from the UE, AF, or 5GCNF; the service request uses data collected and / or generated by the data service; optionally, the service request may include (R)AN node information. Optionally, the (R)AN node information may include a TAI list and / or a Cell Identifier (CI) list. Optionally, the (R)AN node information may be information about the access network equipment in the previous embodiments.

[0563] Optionally, DSTM selects a DPF to handle the data requested for service. For DPF selection, information about (R)AN nodes, DPF capacity, and / or DPF load balancing can be considered.

[0564] Optionally, if the DSFTMF does not receive (R)AN node information, it selects the DPF based on the region or location where the service data is collected. Optionally, (R)AN node information can be retrieved through the Network Repository Function (NRF) or local configuration.

[0565] Optionally, if the DSFTMF does not receive (R)AN node information and the area or location for collecting service data, it may select the DSF based on local information, such as the locally configured service area or relevant location information obtained through positioning, or without considering location information.

[0566] Optionally, DSTM selects a DPF to process the data for the requested service. For DPF selection, information about (R)AN nodes, capacity, and / or load balancing may be considered.

[0567] Step S8102: Establish a data connection between the DSFTMF and the DPF.

[0568] Optionally, the connection between the (R)AN node and the DPF can be shared by data services that require data interaction between the (R)AN node and the DPF, or it can be dedicated to a specific data service. The sharing of the connection between the (R)AN node and the DPF can be determined based on the service type or the number of service types of the data flow between the (R)AN node and the DPF or any data flow.

[0569] Optionally, if no available connection is established between the indicated or selected (R)AN node and the DPF, the DSTMF assigns an identifier to identify the connection and requests the establishment of a connection by setting the DPF as the end node of the connection. The address information of the DPF for this connection can be obtained by the DSTMF during DPF selection, or it can be assigned by the DSTMF or the DPF.

[0570] Optionally, connection-related information is stored in DSTMF and / or DPF.

[0571] Step S8103, DSTMF selects UPF. Optionally, DSTMF selects UPF based on (R)AN node information and / or DPF address information.

[0572] Optionally, DSTMF can select UPF based on the (R)AN node information obtained in step S8101.

[0573] Optionally, DSTMF selects a UPF based on the (R)AN node information to be connected, such as selecting a UPF based on the list of TAIs or CIs supported by (R)AN.

[0574] Optionally, if the DSTMF does not receive (R)AN node information, it selects the UPF based on the region or location where service data is collected. Here, (R)AN node information is unavailable, but the region or location used for collecting service data (e.g., sensing data) is available. This region or location for collecting service data can also be used to determine the (R)AN node information.

[0575] Optionally, the UPF needs to support attachable functionality to process uplink non-UE-related data received from the (R)AN node and / or downlink non-UE-related data received from the DPF. This non-UE data can be data acquired and / or generated by the (R)AN node.

[0576] Optionally, for the following steps, only one UPF is mentioned in the connection path; however, it may include multiple UPFs, such as N3 UPF, PDU session anchor (PSA) UPF, and one or more intermediate UPFs.

[0577] Step S8104: Establish a data connection between DSTMF and UPF.

[0578] Optionally, the DSTMF establishes a data connection with the UPF selected in step S8103 and obtains the address information of the UPF used for connection on the UPF.

[0579] In step S8105, DSTMF calls the Nran_Communication_DSTConnection Request service to request the establishment of a connection between the (R)AN node and the DPF.

[0580] Optionally, the service being invoked may involve N2 information.

[0581] Optionally, the N2 information may include the address information of the selected UPF, the connection identifier, and the address information of the selected DPF.

[0582] Optionally, the N2 information may also include the transport protocol used for data transmission over the connection. If the connection between the (R)AN node and the UPF uses GTP-U, the UPF's address information may include the GTP-U tunnel ID and the IP address of the selected UPF. If the connection between the (R)AN node and the UPF does not use GTP-U, the UPF's address information does not include the GTP-U tunnel ID; for example, if QUIC is indicated, the (R)AN node should establish a QUIC connection with the DPF, and the connection between the (R)AN node and the UPF may be a QUIC connection or an IP connection without a GTP-U tunnel.

[0583] Step S8106, the (R)AN node establishes a connection. Optionally, the (R)AN node establishes a connection between itself and the DPF.

[0584] Optionally, the (R)AN node receives information for connection management (e.g., N2 information); the (R)AN node should establish a connection with the received CN node (e.g., DPF). The (R)AN node records the CN node address information of the selected UPF and configures the path between the (R)AN node and the UPF as described in step S8105.

[0585] Optionally, if the information used for connection management (e.g., N2 information) includes the address information of the DPF, the data generated from the (R)AN node is grouped with the destination address set by the address information of the DPF (e.g., IP address).

[0586] Optionally, if the information used for connection management includes the transport protocol for data transmission over the connection, the (R)AN node establishes a corresponding connection with the DPF and packets the data using the indicated transport protocol. For example, if QUIC is indicated, the (R)AN node establishes a QUIC connection with the DPF. Optionally, other transport protocols can also be used, such as reusing existing GTP-U, or directly using TCP / IP or IP instead of GTP-U.

[0587] Optionally, the (R)AN node sends uplink data to the DPF via the UPF. For example, the (R)AN node sends uplink data to the UPF, and the UPF forwards the uplink data to the DPF.

[0588] In step S8107, the (R)AN node responds to the DSTMF by invoking the Nran_Communication_DSTConnection Response service or through the output of the Nran_Communication_DSTConnection Request service.

[0589] Optionally, the (R)AN node address information may include tunnel information (or identifier) ​​and / or IP address and / or port number.

[0590] Optionally, if the transport protocol used for the connection is GTP-U, the address information of the (R)AN node includes the GTP-U tunnel ID and the IP address of the (R)AN node. If GTP-U is not used, the GTP-U tunnel ID is not included; for example, if QUIC is indicated, the (R)AN node establishes a QUIC connection with the DPF, and the address information of the (R)AN node includes the QUIC connection identifier of the (R)AN node.

[0591] Optionally, if the transport protocol requested in step S8105 is one or more transport protocols, or if the transport protocols requested in step S8105 can be a list including one or more transport protocols. If the transport protocol requested in step S8105 is multiple transport protocols, the transport protocol returned in step S8107 can be one or more of the requested multiple transport protocols. Optionally, returning one or more transport protocols in step S8107 can indicate the encapsulation capability of the data packets supporting the corresponding one or more transport protocols; or, the encapsulation capability of the data packets of the one or more transport protocols can be indicated in other ways.

[0592] Optionally, if step S8105 can request multiple paths, and each path can request multiple transport protocols, then step S8107 can respond to one or more transport protocols among the multiple transport protocols of the requested at least one path. Optionally, step S8107 returning one or more transport protocols among the multiple transport protocols of at least one path may indicate: the encapsulation capability of the data packets corresponding to the one or more transport protocols supporting the at least one path; or the encapsulation capability of the data packets of the one or more transport protocols may be indicated in other ways.

[0593] Optionally, if step S8105 can request multiple transport protocols for the end-to-end full path, then step S8107 can respond to one of the multiple transport protocols for the full path requested by the request. Optionally, step S8107 returning one of the multiple transport protocols for the full path may mean: returning the encapsulation capability of a data packet corresponding to one of the multiple transport protocols supporting the full path; or, the encapsulation capability of the data packets of the one or more transport protocols may be indicated in other ways.

[0594] Optionally, if step S8105 does not request a transport protocol, step S8107 may also request one or more transport protocols.

[0595] Optionally, the (R)AN node sends uplink data to the DPF via the UPF. For example, the (R)AN node sends uplink data to the UPF, and the UPF forwards the uplink data to the DPF.

[0596] In step S8108, the DSTMF sends a Data Connection Modification Request to the UPF.

[0597] In step S8109, the UPF sends a Data Connection Modification Response to the DSTMF.

[0598] Optionally, steps S8108 and S8109 perform a data connection modification process between the DSTMF and the UPF. The DSTMF provides the UPF with (R)AN node address information and corresponding forwarding rules to forward data between the (R)AN and the DPF. If GTP-U is used, the connection between the UPF and the DPF can be a GTP-U tunnel. The connection between the UPF and the DPF can also be a non-3GPP tunnel or other tunnels, such as a UDP tunnel, an IP tunnel, or other types of tunnels; this depends on the transport protocol used between the UPF and the DPF.

[0599] Optionally, the DPF sends downlink data to the (R)AN node via the UPF. For example, the DPF sends downlink data to the UPF, and the UPF forwards the downlink data to the (R)AN node.

[0600] Furthermore, the connection established as described above can also be modified or released. Service requests with data service parameters can be sent to the identified (R)AN in a separate message, separate from connection management information, or in a single message along with information used for connection management. Data is exchanged via the connection between the (R)AN and core network functions using the indicated transport protocol.

[0601] Example 2: Establishing a connection between (R)AN nodes and core network functions that do not include UPF.

[0602] In this embodiment, it is assumed that the connection for the (R)AN node and core network (CN) functions is managed by the DSTMF, and the core network function receiving data from the (R)AN node is the DPF. The transmission path from the (R)AN node to the DPF does not involve the UPF. The DSTMF can be deployed together with the SMF or as an enhanced SMF, and the DPF can be a dedicated UPF supporting data processing for data services. Figure 8C shows a schematic diagram of the relevant network functions. The DSTMF can be a general network function for all data services processed in the CN, or it can be part of any specific network function for a specific data service, such as the LMF, SF, or NWDAF. This embodiment focuses only on connection management functions; other functions for data services can be configured together with the DSTMF and / or DPF, or independently of the DSTMF and / or DPF.

[0603] The connection between the (R)AN node and the DPF can be shared by data services that require data exchange between the (R)AN node and the DPF node, or it can be dedicated to a specific data service.

[0604] Figure 8D is a flowchart illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 8D, the present disclosure relates to an information processing method, which includes:

[0605] In step S8201, DSTMF selects DPF and determines that a connection needs to be established between the (R)AN node and the DPF.

[0606] Optionally, step S8201 is similar to step S8101.

[0607] Step S8202: Establish a data connection between the DSFTMF and DPF.

[0608] Optionally, step S8202 is similar to step S8102.

[0609] In step S8203, DSTMF calls the Nran_Communication_DSTConnection Request service to request the establishment of a connection between the (R)AN node and the DPF.

[0610] Optionally, the service being invoked may involve N2 information.

[0611] Optionally, the N2 information may include the address information of the selected UPF, the connection identifier, and the address information of the selected DPF.

[0612] Optionally, the N2 information may also include the transport protocol used for data transmission over the connection. If the connection between the (R)AN node and the DPF uses GTP-U, the UPF's address information may include the GTP-U tunnel ID and the IP address of the selected UPF. If the connection between the (R)AN node and the DPF does not use GTP-U, the UPF's address information does not include the GTP-U tunnel ID; for example, if QUIC is indicated, the (R)AN node should establish a QUIC connection with the DPF, and the connection between the (R)AN node and the UPF may be a QUIC connection or an IP connection without a GTP-U tunnel.

[0613] Step S8204: The (R)AN node establishes a connection. Optionally, the (R)AN node establishes a connection between itself and the DPF.

[0614] Optionally, the (R)AN node receives information for connection management (e.g., N2 information); the (R)AN node should establish a connection with the received CN node (e.g., DPF).

[0615] Optionally, if the information used for connection management includes the transport protocol for data transmission over the connection, the (R)AN node establishes a corresponding connection with the DPF and packets the data using the indicated transport protocol. For example, if QUIC is indicated, the (R)AN node establishes a QUIC connection with the DPF. Optionally, other transport protocols can also be used, such as reusing existing GTP-U, or directly using TCP / IP or IP instead of GTP-U.

[0616] In step S8205, the (R)AN node invokes the output of the Nran_Communication_DSTConnection Response service or the Nran_Communication_DSTConnection Request service to respond to the DSTMF.

[0617] Optionally, the (R)AN node address information may include tunnel information (or identifier) ​​and / or IP address and / or port number.

[0618] Optionally, if the transport protocol used for the connection is GTP-UE, the address information of the (R)AN node includes the GTP-U tunnel ID and the IP address of the (R)AN node. If GTP-U is not used, the GTP-U tunnel ID is not included; for example, if QUIC is indicated, the (R)AN node establishes a QUIC connection with the DPF, and the address information of the (R)AN node includes the QUIC connection identifier of the (R)AN node.

[0619] Optionally, if the transport protocol requested in step S8203 is one or more transport protocols, or if the transport protocols requested in step S8203 can be a list including one or more transport protocols. If the transport protocol requested in step S8203 is multiple transport protocols, the transport protocol returned in step S8205 can be one or more of the requested multiple transport protocols. Optionally, returning one or more transport protocols in step S8205 can indicate the encapsulation capability of the data packets supporting the corresponding one or more transport protocols; or, the encapsulation capability of the data packets of the one or more transport protocols can be indicated in other ways.

[0620] Optionally, if step S8203 can request multiple paths, and each path can request multiple transport protocols, then step S8205 can respond to one or more transport protocols among the multiple transport protocols of the requested at least one path. Optionally, step S8205 returning one or more transport protocols among the multiple transport protocols of at least one path may indicate: the encapsulation capability of the data packets corresponding to the one or more transport protocols supporting the at least one path; or the encapsulation capability of the data packets of the one or more transport protocols may be indicated in other ways.

[0621] Optionally, if step S8203 can request multiple transport protocols for the end-to-end full path, then step S8205 can respond to one of the multiple transport protocols for the full path requested by the request. Optionally, step S8205 returning one of the multiple transport protocols for the full path may mean: returning the encapsulation capability of a data packet corresponding to one of the multiple transport protocols supporting the full path; or, the encapsulation capability of the data packets of the one or more transport protocols may be indicated in other ways.

[0622] Optionally, if step S8203 does not request a transport protocol, step S8205 may also request one or more transport protocols.

[0623] Optionally, the DPF sends downlink data to the (R)AN node.

[0624] In step S8206, the DSMMF sends a data connection modification request to the DPF.

[0625] In step S8207, the DPF sends a data connection modification response to the DSTMF.

[0626] Optionally, steps S8206 and S8207 perform a data connection modification process between the DSTMF and the DPF. The DSTMF provides the DPF with (R)AN node address information and corresponding forwarding rules to forward data between the (R)AN and the DPF. If GTP-U is used, the connection between the UPF and the DPF can be a GTP-U tunnel. The connection between the UPF and the DPF can also be a non-3GPP tunnel or other tunnels, such as a UDP tunnel, an IP tunnel, or other types of tunnels.

[0627] Optionally, the (R)AN node sends downlink data to the DPF.

[0628] Furthermore, the connection established as described above can also be modified or released. Service requests with data service parameters can be sent to the identified (R)AN in a separate message, separate from connection management information, or in a single message along with information used for connection management. Data is exchanged via the connection between the (R)AN and the core network functions using the indicated transport protocol.

[0629] In some embodiments, under a service-based architecture (SBA), sending a request is achieved by invoking the corresponding service. For example, if the access network node (e.g., (R)AN mentioned above) supports the Service-Based Interface (SBI) interface with DSTMF, sending a request by calling Nran_Communication_DSTConnection using the above scheme is achieved by invoking the corresponding service, and the corresponding response is the result returned by the service call. If the access network node does not support the Service-Based Interface (SBI) interface, the interaction between the corresponding network nodes is achieved by sending corresponding messages.

[0630] In this embodiment of the disclosure, some or all of the steps and their optional implementations can be arbitrarily combined with some or all of the steps in other embodiments, or arbitrarily combined with the optional implementations in other embodiments.

[0631] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0632] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an Application-Specific Integrated Circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), which can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0633] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a Digital Signal Processor (DSP).
