[0211] Figure 1a is an exemplary architecture diagram of a bearer establishment system according to an embodiment of this disclosure. As shown in Figure 1a, the bearer establishment system 100 includes a terminal device 101, an access network device 102, and a core network device 103. It should be understood that the number and form of each device shown in Figure 1a are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, it may include two or more terminal devices, two or more access network devices, and two or more core network devices. The bearer establishment system 100 shown in Figure 1a is only illustrated by example, including one terminal device 101, one access network device 102, and one core network device 103.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0215] In some embodiments, the access network device 102 may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0216] In some embodiments, the core network device 103 may be a single device, including a first network element, a second network element, etc., or it may be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements may be virtual or physical. The core network device 103 may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0217] In some embodiments, the first network element and the second network element are, for example, one or more network elements selected from the following: Session Management Function (SMF) network element, Policy Control Function (PCF) network element, Access and Mobility Management Function (AMF) network element, Location Management Function (LMF) network element, etc.

[0218] It is understood that the bearer establishment system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of this disclosure are also applicable to similar technical problems.

[0219] The following embodiments of this disclosure can be applied to the bearer establishment system 100 shown in FIG1a, or to some of the main entities, but are not limited thereto. The entities shown in FIG1a are illustrative. The bearer establishment system may include all or some of the main entities in FIG1a, or may include other entities other than those in FIG1a. The number and form of each entity are arbitrary. Each entity may be physical or virtual. The connection relationship between the entities is illustrative. The entities may not be connected or may be connected. The connection may be in any way, such as direct connection or indirect connection, wired connection or wireless connection.

[0220] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0221] For 5G, data transmission occurs between the terminal device and the data network (DN). Signaling is transmitted between the terminal device and the data network via the control plane (CP) or the user plane (UP).

[0222] For example, please refer to Figure 1b, which is an exemplary schematic diagram of signaling transmission involved in an embodiment of this disclosure. As shown in Figure 1b, taking LPP signaling between a terminal device and a Location Management Function (LMF) as an example, the transmission path of LPP signaling is: terminal device, access network device (e.g., gNB), Access and Mobility Management Function (AMF), LMF. When transmitting LPP signaling through the user plane, a Protocol Data Unit (PDU) session needs to be established to transmit data. The Protocol Data Unit (PDU) session refers to the association between the terminal and the data network, which provides PDU connection services. Based on the request of the terminal device, the data network can establish a PDU session. The data interaction path between the terminal device and the data network is: terminal device, access network device, User Plane Function (UPF), data network.

[0223] With the advent of the 6th Generation Mobile Communication Technology (6G) era, 6G services take on various forms. Service producers and consumers are no longer limited to the terminal device and data network, but can also be between the terminal device and core network equipment, between terminal devices, between the terminal device and access network equipment (core network equipment is such as a base station, where the base station can be a base station that communicates with the terminal device through an air interface, i.e., the terminal's serving base station, or it can be a non-serving base station), and so on.

[0224] However, for services between terminal devices and core network equipment, if existing control plane or user plane methods are still used to establish data channels, data transmission efficiency will be relatively low. For example, transmission through the control plane requires forwarding via AMF, while transmission through the user plane requires forwarding via UPF. These forwardings increase data transmission latency, consume network bandwidth, and increase the processing capacity requirements of the corresponding nodes. In addition, the protocol stacks used by terminal devices as service producers and consumers (e.g., NAS / RRC signaling used in the control plane scheme) differ from the service interfaces used by the core network equipment, which also increases the complexity of standardization and implementation.

[0225] To address the aforementioned issues, this disclosure provides a method, apparatus, device, system, storage medium, and program product for establishing a wireless bearer. Terminal devices access a Service Based Interface (SBI) message bus, enabling them to provide services to core network elements / functions, other terminal devices, and access network devices. They can also utilize services provided by these entities through the SBI message bus. Simultaneously, a wireless bearer is established for the terminal devices to transmit service data when providing or using services, without traversing the aforementioned control plane or user plane. This reduces data transmission latency, lowers network bandwidth consumption and network node processing capacity requirements, and improves data transmission efficiency.

[0226] The following description, in conjunction with the accompanying drawings, details the bearer establishment method, apparatus, equipment, system, storage medium, and program products provided in this disclosure.

[0227] In some embodiments, a Network Function Service (NF service) is a capability provided by a Network Function Producer to other authorized Network Function Consumers (NF Service Consumers) through a service interface. A Network Function Service may support one or more Network Function Service operations. Network functions may provide different functionalities and therefore provide different Network Function Services.

[0228] In some embodiments, an SBI represents a set of services provided or exposed by a given network function, and the SBI is where NF service operations are invoked. Referring to Figure 1c, which is an exemplary schematic diagram of the protocol stack of an SBI according to an embodiment of this disclosure. In a service-oriented architecture, various network functions that provide and use network function services are connected to the SBI message bus.

[0229] In some embodiments, in a service-oriented architecture, various network functions that provide and use services are connected to the SBI Message Bus. For example, please refer to FIG1d, which is an exemplary schematic diagram of a service-oriented architecture according to an embodiment of this disclosure. As shown in FIG1d, core network functions (e.g., AMF, SMF, PCF, etc.) are all connected to the SBI bus.

[0230] In some embodiments, the aforementioned terminal device access to the SBI message bus means that, from the perspective of Internet Protocol Address (IP), the network functions of the terminal device and the core network device are equivalent, and the IP address of the terminal device can be addressed and routed in the transport network composed of the access network device and the core network device.

[0231] In some embodiments, the services that the terminal device can provide or use include, but are not limited to, artificial intelligence (AI) services, sensing services, and services deployed on core network equipment.

[0232] In some embodiments, for AI services, terminal devices, access network devices, and core network devices can all be producers (i.e., providers of AI services) or consumers (i.e., users of AI services provided by other network nodes).

[0233] In some embodiments, for sensing services, the terminal device can collect sensing data based on wireless sensing capabilities, such as collecting 3D point cloud data, which includes spatial information and velocity information of the sensed objects. In this case, the terminal device is the producer of sensing data. Correspondingly, the terminal device can also obtain sensing data from access network devices, core network devices, and other terminal devices, in which case the terminal device is the consumer of sensing data.

[0234] In some embodiments, for services deployed on core network equipment, such as Extended Reality (XR) services, terminal devices can send data (e.g., pose information) to the core network equipment. The core network equipment then performs the corresponding rendering calculations using its computing capabilities before sending the data back to the terminal device. In this case, the core network equipment is the producer of the XR service.

[0235] In some embodiments, the terminal device provided in this application may be a general commercial terminal, or it may be a low-cost terminal.

[0236] Referring to Figure 2a, Figure 2a is an exemplary interactive schematic diagram of a bearer establishment method provided according to an embodiment of the present disclosure. As shown in Figure 2a, the bearer establishment method includes the following steps:

[0237] Step S2101: The access network device obtains service-related information and / or auxiliary information from the terminal device.

[0238] In some embodiments, the name of business-related information is not limited, and it may be, for example, "business information", "related information", "reservation information", "service information", etc.

[0239] In some embodiments, the configured radio bearer is associated with a service provided or used by the terminal device through the SBI message bus. That is, the configured radio bearer is used to transmit service data for the service provided or used by the terminal device through the SBI message bus.

[0240] In some embodiments, service-related information is used to indicate whether the terminal device has any services related to providing or using services. For example, service-related information may indicate, but is not limited to, at least one of the following: the terminal device's subscription information (e.g., the terminal device only provides services, only uses services, or provides and uses services simultaneously), historical bearer establishment information, or auxiliary information of the terminal device, etc.

[0241] In some embodiments, service-related information includes, but is not limited to, at least one of the following: the application type corresponding to the service (e.g., AI service, sensing service, or service deployed on core network equipment), whether the service is related to the terminal providing or using the service, application identifier, quality of service (QoS) rules, QoS identifier (ID), packet filtering rules, packet filtering rule identifier, Internet Protocol (IP) address restrictions, port number restrictions, etc.

[0242] In some embodiments, service-related information is obtained from core network equipment or terminal equipment.

[0243] In some embodiments, the access network device may obtain service-related information from the core network device when or after the terminal device establishes a radio bearer, or obtain the service-related information before establishing the radio bearer.

[0244] In some embodiments, when or after a terminal device establishes a wireless RRC connection, the access network device obtains service-related information of the terminal device from the core network device. Optionally, the core network device can provide service-related information through the context of the terminal device (e.g., the core network can provide service-related information through a context response message). Alternatively, the core network device can also provide service-related information of the terminal device through separate signaling.

[0245] Optionally, the access network device may store service-related information for a period of time after acquiring it, for use in subsequent radio bearer establishment, without needing to acquire the service-related information every time a radio bearer is established. Optionally, the access network device may maintain service-related information continuously while the terminal device is in a connected state. After the access network device releases the terminal device into an idle state, it may delete the information or continue to store it for a period of time. If the terminal device enters an inactive state, the access network device may continue to store the service-related information.

[0246] In some embodiments, the core network device can update service-related information in real time and send the updated service-related information to the access network device in real time.

[0247] In some embodiments, the core network equipment mentioned above includes, but is not limited to, one or more network elements such as AMF, PCF, SMF, and UPF.

[0248] In some embodiments, the name of the auxiliary information is not limited, and it may be, for example, "capability information," "configuration information," etc.

[0249] In some embodiments, the aforementioned auxiliary information is obtained from a terminal device or a core network device.

[0250] In some embodiments, auxiliary information is used to indicate whether the terminal device has any services related to providing or using services. Here, "whether or not" can be understood as whether there are currently any services related to providing or using services on the terminal device, or whether there may be services related to providing or using services on the terminal device in the future, or whether the user is interested in services related to providing or using services on the terminal device.

[0251] In some embodiments, the terminal device may report the aforementioned auxiliary information via radio signaling. This radio signaling includes, but is not limited to, RRC messages or Non-Access Stratum (NAS) signaling. Optionally, when the terminal device reports the aforementioned auxiliary information via radio signaling, the access network device may store the auxiliary information in the core network device when releasing the context of the terminal device.

[0252] In some embodiments, the terms "radio" and "wireless" can be used interchangeably; the terms "radio access network (RAN)," "access network (AN)," and "RAN-based" can be used interchangeably.

[0253] In step S2102, the access network device determines whether it is necessary to establish a radio bearer for the terminal device based on service-related information and / or auxiliary information.

[0254] In some embodiments, if service-related information and / or auxiliary information are used to indicate that the terminal device currently has a service related to providing or using the service, it is determined that a radio bearer needs to be established for the terminal device.

[0255] In some embodiments, the radio bearer is a dedicated radio bearer. The dedicated radio bearer is used to transmit service data for a specific service. Optionally, when the access network device determines that the terminal device has not yet configured a dedicated radio bearer, it determines to establish a dedicated radio bearer for the terminal device.

[0256] In some embodiments, the radio bearer is a default radio bearer. The default radio bearer can be used to transmit service data related to the terminal providing or using the service. Optionally, when the access network device determines that the terminal device has not yet configured a dedicated radio bearer or a default radio bearer, it determines to establish a default radio bearer for the terminal device.

[0257] In some embodiments, a dedicated radio bearer has a higher priority than a default radio bearer. That is, if the terminal device is configured with both a dedicated radio bearer and a default radio bearer, and service data can be mapped to both, the dedicated radio bearer is used to transmit the service data. For example, when transmitting service data for a specific service that can be mapped to a dedicated radio bearer, the service data is transmitted via the dedicated radio bearer; when transmitting service data for a specific service that cannot be mapped to a dedicated radio bearer, the service data is transmitted via the default radio bearer.

[0258] In some embodiments, the wireless bearer includes an uplink data channel and / or a downlink data channel. The uplink data channel is used to transmit uplink data, and the downlink data channel is used to transmit downlink data.

[0259] In step S2103, when the access network device determines that it needs to establish a radio bearer for the terminal device, it sends configuration information to the terminal device.

[0260] In some embodiments, configuration information is used to establish a wireless bearer.

[0261] In some embodiments, configuration information is used by the terminal device to determine which service data can be mapped to the radio bearer.

[0262] In some embodiments, the configuration information includes, but is not limited to, at least one of the following: the application type, application identifier, packet filtering rules, QoS ID, etc., corresponding to the service data that can use the radio bearer. Packet filtering rules may include, for example, IP address restrictions, port number restrictions, etc.

[0263] In some embodiments, after receiving configuration information, the terminal device establishes a radio bearer based on the configuration information.

[0264] In some embodiments, the names of configuration information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "indication", "instruction", "command", "channel", and "parameter" can be used interchangeably.

[0265] In step S2104, the terminal device establishes a wireless bearer based on the configuration information.

[0266] In some embodiments, after receiving configuration information, the terminal device can send a request message to the network to obtain the radio resources corresponding to the radio bearer. Accordingly, the network can allocate radio resources and configuration parameters to the terminal device based on the terminal device's request. Further, the terminal device configures itself according to the allocated radio resources and configuration parameters to establish the radio bearer. Optionally, radio resources include, but are not limited to, frequency resources, time slots, etc., and configuration parameters include, for example, power control parameters.

[0267] In some embodiments, when a terminal device enters an inactive state, it can maintain the currently established radio bearer. If the terminal device supports data transmission in the inactive state, it can use the radio bearer to transmit service data in the inactive state.

[0268] It should be noted that the bearer establishment method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, steps S2103 to S2104 may be implemented as independent embodiments; step S2104 may be implemented as an independent embodiment.

[0269] Referring to Figure 2b, which is an exemplary interactive schematic diagram of a bearer establishment method provided according to an embodiment of the present disclosure, as shown in Figure 2c, the bearer establishment method includes the following steps:

[0270] Step S2201: The access network device sends the first signaling to the terminal device.

[0271] In some embodiments, the first signaling may be a broadcast message or RRC-specific signaling. The first signaling is used to instruct the terminal device to allow the sending of a request message, which requests configuration for the terminal device to provide services and / or use the service channel.

[0272] In step S2202, the core network equipment sends a second signaling message to the terminal equipment.

[0273] In some embodiments, the second signaling may be a NAS message. The second signaling is used to instruct the terminal device to allow the sending of a request message, which requests configuration for the terminal device to provide services and / or use the service channel.

[0274] In step S2203, the terminal device sends a request message to the core network device according to the first signaling and / or the second signaling.

[0275] In some embodiments, the names of the first signaling, the second signaling, the request message, etc., are not limited to the names described in the embodiments. Terms such as "signaling", "information", "message", "signal", "report", "indication", "instruction", "command", "channel", and "parameter" can be used interchangeably.

[0276] In some embodiments, when the terminal device receives the first signaling and / or the second signaling, it indicates that the access network device and / or the core network device allow the terminal to send a request message. At this time, the terminal device sends a request message to the core network to request the establishment of a radio bearer. The radio bearer is used to transmit service data for the service channel.

[0277] In some embodiments, the request message is sent as a carrier of at least one of the following messages:

[0278] Connection establishment request;

[0279] Connection established successfully;

[0280] Connection restoration request.

[0281] In some embodiments, the terminal device may use a NAS message to send a request message to the core network device. The NAS message is included in an RRC message sent by the terminal device to the access network device. After receiving the RRC message, the access network device sends the NAS message from the RRC message to the core network device.

[0282] In some embodiments, the request message includes business-related information.

[0283] In some embodiments, service-related information is used to indicate whether the terminal device has any services related to providing or using services. For example, service-related information may indicate, but is not limited to, at least one of the following: the terminal device's subscription information (e.g., the terminal device only provides services, only uses services, or provides and uses services simultaneously), historical bearer establishment information, or auxiliary information of the terminal device, etc.

[0284] Step S2204: The terminal device sends service-related information to the access network device.

[0285] In some embodiments, the terminal device may send all of the above-mentioned service-related information to the access network device. Alternatively, it may send at least some of the above-mentioned service-related information to the access network device, for example, the terminal device may only provide the service, only use the service, or provide and use the service simultaneously.

[0286] In step S2205, the core network device sends a second response message to the access network device.

[0287] In some embodiments, after receiving a request message, the core network device sends a second response message to the access network device to indicate whether to accept the request from the terminal device.

[0288] In some embodiments, the second response message includes, but is not limited to, at least one of the following: information about the established service channel, QoS rules, packet filtering rules, terminal device IP address, etc.

[0289] In some embodiments, the service channel in the above-disclosed embodiments may be a Protocol Data Unit (PDU) session.

[0290] Step S2206: The access network device sends a third signaling message to the terminal device.

[0291] In step S2207, the terminal device establishes a radio bearer based on the third signaling.

[0292] In some embodiments, the third signaling is a reconfiguration message. Optionally, the reconfiguration message includes radio resources and configuration parameters allocated to the terminal device. The radio resources include, but are not limited to, frequency resources and time slots, and the configuration parameters include power control parameters.

[0293] In some embodiments, the third signaling is an RRC message.

[0294] In some embodiments, the third signaling includes configuration information.

[0295] In some embodiments, configuration information is used to configure the radio bearer.

[0296] In some embodiments, configuration information is used by the terminal device to determine which service data can be mapped to the radio bearer.

[0297] In some embodiments, the terminal device establishes a radio bearer for the aforementioned service channel based on the configuration information in the third signaling, and establishes a mapping rule from the QoS Flow Identifier (QFI) to the radio bearer.

[0298] In some embodiments, the terminal device configures itself according to allocated radio resources and configuration parameters to establish a radio bearer. Optionally, the terminal device may also activate the currently established radio bearer. For example, the terminal device may configure physical layer and MAC layer parameters to ensure that data can be transmitted through the newly established bearer.
