[0004] When managing assets in a factory, the reader can be a special terminal in the factory for A-IoT business; when managing assets of a user, the reader can be a smart mobile terminal (e.g., a mobile phone, etc.) of the user. Such readers can be collectively referred to as a terminal reader (UE-reader). In order to improve the efficiency of inventory or location services, in a certain area, it is desirable to find the same ambient Internet of Things device through as many readers as possible. Therefore, how to reasonably select readers and complete A-IoT business through the readers is a problem to be solved. SUMMARY

[0084] The scheme of this application will be further described below with reference to the accompanying drawings.

[0085] The technical solution provided in this application can be applied to various communication systems, such as fifth-generation (5G) communication systems. th This technology can be applied to various scenarios, including 5G mobile communication systems, future evolution systems, and converged communication systems, as well as existing communication systems. The application scenarios of the technical solutions provided in this application can include multiple areas, such as machine-to-machine (M2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine-type communication (mMTC). These scenarios may include, but are not limited to, communication between terminals, communication between network devices, and communication between network devices and terminals. Network devices include access network devices and core network devices. The following descriptions use examples of applications involving communication between network devices and terminals.

[0086] Figure 1 shows a schematic illustration of one possible, non-limiting, communication system. As shown in Figure 1, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. The communication system 1000 can also include the Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1), etc., can also be included in the RAN 100. The terminals 120 are connected to the RAN nodes 110 wirelessly. The RAN nodes 110 are connected to the core network 200 wirelessly or wired. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the radio access network respectively.

[0087] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G mobile communication system, or a future communication network (or future mobile communication system). The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0088] The RAN nodes 110 can also be referred to as network devices, access network devices, RAN entities, or access nodes, etc., which form part of the communication system to help terminals to access wirelessly. The RAN nodes 110 in the communication system 1000 can be of the same type or of different types. In some scenarios, the roles of the RAN nodes 110 and the terminals 120 are relative, e.g., the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured to be a mobile base station. For a terminal 120j that accesses to the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 1 can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0089] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (such as 110a in FIG. 1), a micro base station or an indoor station (such as 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the network device in a vehicle to everything (V2X) technology can be a road side unit (RSU).

[0090] In another possible scenario, a terminal is assisted by multiple RAN nodes to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a central unit-control plane (CU-CP), a central unit-user plane (CU-UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0091] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an open-central unit (O-CU), the DU can also be referred to as an open-distributed unit (O-DU), the CU-CP can also be referred to as an open-central unit-control plane (O-CU-CP), the CU-UP can also be referred to as an open-central unit-user plane (O-CU-UP), and the RU can also be referred to as an open-radio unit (O-RU). For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0092] The terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D) communication, vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IoT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, unmanned aerial vehicle, helicopter, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the device form of the terminal.

[0093] The communication between the network device and the terminal follows a certain protocol layer structure. The protocol layer can include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer can include at least one of a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer, etc. The user plane protocol layer can include at least one of a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer, etc. The non-access stratum (NAS) of the terminal and the NAS interaction of the access and mobility management function (AMF) of the core network; the RRC layer of the UE and the RRC interaction of the access network device.

[0094] The base station and the terminal can be fixed in position or mobile. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; can also be deployed on airplanes, balloons and artificial satellites. The embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0095] The roles of the base station and the terminal can be relative, for example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile base station, and for those terminals 120j that access the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through a wireless air interface protocol. Of course, 110a and 120i can also communicate through an interface protocol between base stations and base stations, at this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can be collectively referred to as a communication device, 110a and 110b in FIG. 1 can be referred to as a communication device with a base station function, and 120a-120j in FIG. 1 can be referred to as a communication device with a terminal function.

[0096] In the embodiments of the present application, the base station is also referred to as a network device, and the apparatus for implementing the functions of the network device can be the network device, or can be an apparatus capable of supporting the network device to implement the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The apparatus can be installed in the network device or used in combination with the network device. In the embodiments of the present application, only the apparatus for implementing the functions of the network device is taken as an example for description, and the scheme of the embodiments of the present application is not limited in this way.

[0097] In addition, in the embodiments of the present application, the UE is also referred to as a terminal, and the apparatus for implementing the method flow of the embodiments can be the terminal. Correspondingly, the method can also be implemented by an apparatus capable of supporting the terminal to implement the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The apparatus can be installed in the terminal or used in combination with the terminal. In the embodiments of the present application, only the apparatus for implementing the functions of the terminal is taken as an example for description, and the scheme of the embodiments of the present application is not limited in this way.

[0098] It should be understood that the number and types of devices in the communication system shown in FIG. 1 are only illustrative, and the present application is not limited thereto. In actual applications, more terminals, more access network devices, and other network elements, such as core network devices and / or network elements for implementing artificial intelligence functions, can also be included in the communication system.

[0099] It can be understood that all or part of the functions implemented by one or more of the terminal, the access network device, the core network device, or the network element for implementing the artificial intelligence function can be virtualized, that is, implemented by one or more of a special processor or a general processor and a corresponding software module. Among them, the terminal and the access network device involve the interface of air interface transmission, and the transceiving function of the interface can be implemented by hardware. The core network device, such as an operation administration and maintenance (OAM) network element, can be virtualized. Optionally, one or more functions of the virtualized terminal, access network device, core network device, or network element for implementing the artificial intelligence function can be implemented by a cloud device, such as a cloud device in an over the top (OTT) system.

[0100] The embodiments of the present application relate to environmental Internet of Things, and the concept thereof is described below.

[0101] With the wide application of Internet of Things (IoT) technology in the field of wireless communication, the performance of reducing the size, complexity and power consumption of IoT devices is attracting much attention. Since most wireless communication devices need to be replaced by manual battery or powered by rechargeable battery, it will cause high maintenance cost and even safety hazards to a certain extent. With the continuous introduction of digital era demand and the improvement of automation level, it is urgent to introduce new IoT technology to support non-energy storage devices or energy storage devices that do not need to be replaced by manual battery or charged. Therefore, the IoT technology that supports higher density connection, lower complexity and lower power consumption - Ambient IoT emerges as the times require. This battery-free IoT device is called A-IoT device. Since there is no battery in A-IoT device, the size of the device is reduced and the complexity of the device is reduced, so it is expected to increase the number of devices that can be accommodated in the IoT scenario. The peak power consumption of A-IoT device is between 1 μW and several hundred μW, and the uplink transmission of A-IoT device can be generated by A-IoT device itself or need to be backscattered based on the externally provided carrier wave to realize the uplink transmission. Among them, the A-IoT device with peak power consumption of 1 μW does not have uplink or downlink amplification function, and the A-IoT device with peak power consumption of several hundred μW has uplink and / or downlink amplification function.

[0102] 3GPP defines several topologies of ambient IoT, which can be seen from Figure 2.

[0103] (1) in Figure 2 is the topology of "base station to ambient IoT device". In this topology, the base station and the ambient IoT device can communicate bidirectionally, including the transmission of ambient IoT data and / or signaling. The base station that sends data to the ambient IoT device and the base station that receives data from the ambient IoT device can be the same or different.

[0104] (2) in Figure 2 is the topology of "base station to intermediate node to ambient IoT device". In this topology, the base station and the intermediate node can communicate Uu, and the intermediate node and the ambient IoT device can communicate bidirectionally, including the transmission of ambient IoT data and / or signaling.

[0105] (3.1) and (3.2) in FIG. 2 are “base station to assisting node to environmental IoT device to base station” topology. (3.1) in FIG. 2 is a downlink assisted topology, in which the base station transmits downlink to the assisting node over Uu interface, and the environmental IoT device receives environmental IoT data and / or signaling from the assisting node and transmits environmental IoT data and / or signaling to the base station. (3.2) in FIG. 2 is an uplink assisted topology, in which the environmental IoT device receives environmental IoT data and / or signaling from the base station and transmits environmental IoT data and / or signaling to the assisting node, and the assisting node transmits uplink to the base station over Uu interface.

[0106] (4) in FIG. 2 is “UE to environmental IoT device” topology. In this topology, the UE and the environmental IoT device can communicate bi-directionally, including transmission of environmental IoT data and / or signaling. The UE transmitting data to the environmental IoT device and the UE receiving data from the environmental IoT device can be the same or different.

[0107] The environmental IoT device has characteristics of low power consumption, low complexity, small size, and long life cycle, and usually does not have a traditional battery, and mainly uses energy obtained from environmental energy, which can include radio waves, solar energy, kinetic energy, thermal energy, and pressure energy or any other form of energy. Radio waves can come from a base station or a user equipment. The environmental IoT device can also be referred to as an IoT device, and as the standard evolves, the environmental IoT device can have other names.

[0108] The intermediate node in FIG. 2 can also be described as a relay node, which can be a relay, a repeater, an integrated access backhaul (IAB) node, a user equipment (UE), or any other device with environmental IoT capability.

[0109] The assisting node in FIG. 2 can be a relay, a repeater, an IAB node, a UE, or any other device with environmental IoT capability.

[0110] The base station, the intermediate node, the assisting node, and the UE in FIG. 2 can be collectively referred to as a reader. The reader can be a device with environmental IoT capability, and can power the environmental IoT device or provide a carrier signal for backscattering to the environmental IoT device. The reader can also be referred to as a reader-writer, a reader, an excitation source, an IoT-capable device, an IoT-functional device, or any other name as the standard evolves. The environmental IoT device can be a UE, a tag, or any other device.

[0111] It can be understood that how the reader specifically communicates with the environmental Internet of Things device depends on which of the base station, intermediate node, auxiliary node and UE the reader is specifically and the specific topology, based on the topology described in the above embodiments, the communication between the reader and the environmental Internet of Things device in the following embodiments can be direct communication (for example, the reader is a base station and the topology is (1) in FIG. 2), or indirect communication (for example, the reader is a base station and the topology is (2) in FIG. 2 or (3.1) in FIG. 2 or (3.2) in FIG. 2). The specific communication process can be referred to the above description of the topology.

[0112] In the A-IoT, at least one of the following operations can be performed between the reader and the environmental Internet of Things device (such as a tag): an inventory operation, a read operation, a write operation, a kill operation, or a lock operation.

[0113] The inventory operation, which can also be referred to as an inventory operation, can obtain the identification of the tag through the inventory operation. For example, the reader can obtain the identification of the tag through commands such as query, acknowledgment (ACK), etc. The inventory operation can be used to confirm whether the tag is currently in the inventory area.

[0114] The specific process of the inventory operation can include:

[0115] 1) The server sends an inventory request to the core network device, to request the core network device to trigger the inventory process;

[0116] 2) The core network device sends an inventory request to the reader, to request the reader to trigger the A-IoT air interface access process, so as to obtain the tag information; wherein the reader can be a network device or a terminal;

[0117] 3) The reader triggers the tag to perform the A-IoT air interface access process, the reader triggers the tag to access, and if the tag responds and successfully accesses, the reader sends the tag information as an inventory report to the core network;

[0118] 4) The core network device can further send the inventory report to the server, so that the server can confirm whether the tag is currently in the inventory area.

[0119] The read operation can read the electronic product code (EPC) or tag identifier (TID) in the storage area of the tag, or read the content stored in the reserved area of the tag or the content stored in the user storage area, etc.

[0120] Write operation, the storage area of the tag can be written.

[0121] Inactivation operation, the tag can never work.

[0122] Lock operation, the information of the tag can be locked to prevent reading operation or writing operation on the tag. Alternatively, the lock operation can also lock the storage area of the tag to prevent reading operation or writing operation on the storage area.

[0123] The above is only an example, and other operations can be performed between the reader and the tag, which will not be enumerated one by one.

[0124] At present, A-IoT mainly considers the warehouse factory, such as managing the assets in the factory, counting the assets through the inventory process, and confirming which assets are stored in the current warehouse. Especially when the reader is a terminal, the reader can be a special terminal in the factory for A-IoT business. However, it can also be considered that A-IoT can be used for other consumer-oriented businesses, such as managing the assets of users, positioning the tags through the inventory process or other similar processes, determining whether the user's items are lost and in which area, thereby realizing the A-IoT-based lost item positioning. At this time, since it involves a wide range of life, the typical reader can be a user's smart mobile terminal (such as a mobile phone, etc.). Such readers can be collectively referred to as terminal readers (UE-reader). In order to improve the efficiency of the inventory or positioning business, in a certain area, it is hoped that as many readers as possible will find the same environment Internet of Things device. Therefore, how to reasonably select the reader and complete the A-IoT business through the reader?

[0125] Therefore, the present application provides a communication scheme, the third device instructs the second device to request or trigger at least one first device to perform a first business on a first environment Internet of Things device, and the second device sends first information to at least one first device, the first information indicating that the first business is requested or triggered by at least one first device, and the first information is carried in a broadcast message. At least one first device sends information of the first environment Internet of Things device to the third device, so that terminal readers can be reasonably selected as much as possible to complete the first business.

[0126] The present application can be applied to the scenario shown in FIG. 3, in which the access network device is generally outdoor and can communicate with the A-IoT device through an indoor intermediate node (such as a UE).

[0127] Based on the above communication system, the communication method provided by the present application is described as follows:

[0128] As shown in FIG. 4, a flow diagram of a communication method provided by an embodiment of the present application is shown. The method can include the following steps:

[0129] S401. The first device sends third information to the third device.

[0130] Correspondingly, the third device receives the third information.

[0131] The first device can be a UE or a module (e.g., a processor, a chip, a chip system, a circuit, etc.) in the UE. The module can be a communication module in the UE or a circuit or chip responsible for communication functions in the UE, such as a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core. Here, the UE can act as a reader or terminal reader. The third device can be a core network device or a module (e.g., a processor, a chip, a chip system, a circuit, etc.) in the core network device. The module can be a communication module in the core network device or a circuit or chip responsible for communication functions in the core network device, such as a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core.

[0132] The first device sends third information to the third device, which indicates the capability information or subscription information of the first device. The third information indicates that the first device supports the first service, or that the first device is capable of the first service, or that the first device expects to perform the first service. The first service is a positioning service, or the first service is used to obtain the location information of the first device, or the first service is used to obtain the location information of the environmental IoT device, such as the location information of the environmental IoT device corresponding to the first device. It should be understood that in the embodiments of the present application, the third information indicating that the first device supports the first service can be replaced by the first device supporting communication with the environmental IoT device, or can be replaced by the first device supporting the reader as the environmental IoT device.

[0133] In one example, the third information can be 1 bit. When the 1 bit is of a first value, it indicates that the first device supports the first service, or that the first device is capable of the first service, or that the first device expects to perform the first service. When the 1 bit is of a second value, it indicates that the first device does not support the first service, or that the first device is not capable of the first service, or that the first device does not expect to perform the first service. The first device can explicitly indicate to the third device whether the first device supports the first service, or whether the first device is capable of the first service, or whether the first device expects to perform the first service by the 1 bit. The third information can be carried in an existing message sent by the first device to the third device. For example, a reserved bit of a field in the existing message can be used to indicate whether the first device supports the first service, or whether the first device is capable of the first service, or whether the first device expects to perform the first service; or a field in the existing message can be multiplexed to indicate whether the first device supports the first service, or whether the first device is capable of the first service, or whether the first device expects to perform the first service; or a new 1 bit can be added in the existing message to indicate whether the first device supports the first service, or whether the first device is capable of the first service, or whether the first device expects to perform the first service. Thus, the existing service process can be compatible, and the change to the protocol or process is small.

[0134] In another example, the first device sends the third information to the third device, i.e., the third information is carried in an existing message by using a reserved bit, or a field in the existing message is multiplexed to represent the third information, or the third information is added in the existing message, which indicates that the first device supports the first service, or that the first device is capable of the first service, or that the first device expects to perform the first service. If the third information is not carried in the existing message by using a reserved bit, or a field in the existing message is not multiplexed to represent the third information, or the third information is not added in the existing message, which indicates that the first device does not support the first service, or that the first device is not capable of the first service, or that the first device does not expect to perform the first service. Thus, the third device can explicitly know whether the first device supports the first service, or whether the first device is capable of the first service, or whether the first device expects to perform the first service. If the first device does not support the first service, or is not capable of the first service, or does not expect to perform the first service, the third information is not carried in the existing message by using a reserved bit, or a field in the existing message is not multiplexed to represent the third information, so that the utilization of resources can be improved, or the third information is not added in the existing message, so that the signaling overhead can be saved.

[0135] Further, the third information further indicates a second frequency band corresponding to the first service supported by the first device. For example, the first device supports the first service in a frequency band (band) A, and the third information further indicates the band A. For another example, the first device supports the first service in the band A and a band B, and the third information further indicates the band A and the band B. The first device indicates the second frequency band corresponding to the first service supported by the first device to the third device, so that the third device can determine which first device to request or trigger to obtain the information of the environmental Internet of Things device according to whether the second frequency band corresponding to the first service supported by the first device and the frequency band corresponding to the first service selected by the third device match. When the frequency band corresponding to the first service selected by the third device does not include the second frequency band, the third device does not request or trigger the first device to obtain the information of the environmental Internet of Things device. Therefore, the efficiency and reliability of obtaining the information of the environmental Internet of Things device can be improved.

[0136] It can be understood that the third device can also obtain the third information before performing the scheme of the embodiment, for example, the third device is configured with the third information by an OAM manner, or the third information is predefined by a protocol. Therefore, the step S401 is optional, which is indicated by a dashed line in FIG. 4.

[0137] For example, the third information can be carried in a non-access stratum (NAS) message.

[0138] S402. The third device sends fourth information to the second device.

[0139] Correspondingly, the second device receives the fourth information.

[0140] For example, the second device can be an access network device.

[0141] For example, the third device obtains the third information of at least one first device, so that the third device can send the fourth information to the second device corresponding to the at least one first device in the case that the third device receives a request of a third party (for example, a server) or a UE to perform a first service. The fourth information indicates that the second device requests or triggers the at least one first device to perform the first service on a first environmental Internet of Things device, which is an environmental Internet of Things device having a corresponding relationship, a mapping relationship or a connection with the at least one first device.

[0142] The fourth information can be a new service indication information. For example, the current A-IoT service types that can be indicated are inventory, read, write, and deactivate, and a new A-IoT service type can be added as the first service, which is a positioning service, or the first service is used to obtain the location information of the first device. Alternatively, the fourth information can be represented by combining an inventory service type indication with a new 1-bit indication bit, for example, indicating that the A-IoT service type is inventory, and simultaneously carrying a 1-bit indication bit to represent that it is an inventory-related process based on A-IoT positioning service, so as to be compatible with the existing inventory message.

[0143] Exemplarily, the fourth information described above can be carried in a paging message sent by the third device to the second device, so that the second device knows that it needs to initiate paging and establish RRC connections with as many first devices as possible to perform the first service.

[0144] Further, the fourth information also indicates the first frequency band corresponding to the first service, that is, the third device indicates that the first service will be performed in the first frequency band, so that the subsequent first device can judge whether the second frequency band supported by itself matches the first frequency band indicated by the fourth information, so as to be able to perform the first service.

[0145] It can be understood that the request or triggering of the first service of the first environmental Internet of Things device by the at least one first device by the second device does not necessarily come from the indication of the third device, for example, it can also be decided by the second device itself. Therefore, the step S402 is optional, which is represented by a dashed line in FIG. 4.

[0146] S403. The second device sends first information to the first device.

[0147] Correspondingly, the first device receives the first information.

[0148] Exemplarily, after the second device receives the fourth information described above, the second device sends first information to the at least one first device. The first information indicates a request or triggering of the at least one first device to perform the first service, or a request or triggering of the at least one first device to perform the first service as a reader.

[0149] The first information can be carried in a broadcast message, so that as many first devices as possible can be notified to establish RRC connections through one broadcast message. Exemplarily, the broadcast message includes at least one of the following: scheduling information of a paging message (for example, downlink control information (DCI) of the paging message), the paging message, and system information.

[0150] For example, in the case that the first information is carried in the paging message, the first information can be included in the paging message as new information, or the first information can be included in the information indicating the paging cause value as one of the paging cause values. At this time, it can be understood that the first device is paged by the first service.

[0151] Further, the first information also indicates a first frequency band corresponding to the first service, i.e., the third device / the second device indicates that the first service will be performed in the first frequency band.

[0152] S404. The first device determines that the first device can perform the first service based on at least one of the first frequency band, the second frequency band, the power of the first device, and the service amount of the first device, i.e., determines that the first device performs the first service.

[0153] After receiving the first information, the first device can determine whether it can perform the first service or whether it performs the first service according to its capability information and / or current state information. For example, the first device can determine whether the second frequency band supported by the first device matches the first frequency band indicated by the first information, whether the power of the first device can perform the first service, and / or whether the first device can perform the first service or whether it performs the first service based on the current service amount (i.e., load) of the first device. In the case that the second frequency band does not match the first frequency band, it is determined that the first device cannot perform the first service; in the case that the power of the first device is low, it is determined that the first device cannot perform the first service; and in the case that the current service amount of the first device is large, it is determined that the first device cannot perform the first service.

[0154] It can be understood that the first device can also determine whether it can perform the first service or whether it performs the first service according to other information. Therefore, the step S404 is optional, which is represented by a dashed line in FIG. 4.

[0155] S405. The first device sends information for establishing an RRC connection to the second device.

[0156] Correspondingly, the second device receives the information for establishing an RRC connection.

[0157] In case the first device determines that the first service can be performed, the first device sends information for establishing an RRC connection to the second device to establish an RRC connection with the second device. For example, the first device sends an RRC reestablishment request (RRCReestablishmentRequest) message to the second device, indicating a request for establishing an RRC connection, and in case the request of the first device is allowed, the second device sends an RRC reestablishment (RRCReestablishment) message to the first device to establish an RRC connection, and the first device further sends an RRC reestablishment complete (RRCReestablishmentComplete) message to the second device.

[0158] Exemplarily, the information for indicating the establishment of the RRC connection comprises a first cause value indicating the first service. For example, the first cause value is included in the RRC reestablishment request message, or the first cause value is included in the RRC reestablishment complete message.

[0159] It can be understood that in case the first device is currently in an RRC connected state, the above steps S402-S405 can be skipped; in case the first device is currently in an RRC non-connected state, i.e. an RRC idle state or an RRC inactive state, the above steps S402-S405 need to be performed. Therefore, the above steps S402-S405 are optional, which are represented by dashed lines in FIG. 4.

[0160] S406. The third device determines at least one first device that can perform the first service.

[0161] Exemplarily, the third device determines at least one first device that can perform the first service according to the above third information and the first device that currently establishes an RRC connection with the second device.

[0162] S407. The third device sends a first request to the first device.

[0163] Correspondingly, the first device receives the first request.

[0164] The third device sends a first request to at least one first device that can perform the first service. The first request is used to request the first device to perform the first service on the first environmental Internet of Things device, for example, to perform positioning on the first environmental Internet of Things device. The first request can comprise identification information of the first environmental Internet of Things device.

[0165] Exemplarily, the first request can be a first service request message, an inventory request or a positioning request.

[0166] Exemplarily, the first request can be forwarded to the first device by the second device, for example, the third device sends the first request to the second device, and the second device further forwards the first request to the first device. For example, the first request can be carried in a non-access stratum (NAS) message.

[0167] S408. The first device triggers the first environmental IoT device to initiate access and report the identification information of the first environmental IoT device and / or the location information of the first environmental IoT device.

[0168] After the first device receives the first request, the first device triggers the first environmental IoT device to initiate access, for example, triggers the first environmental IoT device to initiate access on the A-IoT interface and report the identification information of the first environmental IoT device and / or the location information of the first environmental IoT device.

[0169] S409. The first device sends second information to the third device.

[0170] Correspondingly, the third device receives the second information.

[0171] After the first device successfully receives the first environmental IoT device access and the corresponding identification information of the first environmental IoT device and / or the location information of the first environmental IoT device, the first device sends second information to the third device. The second information indicates the information of the first environmental IoT device. For example, the information of the first environmental IoT device can include at least one of the following: the identification information of the first environmental IoT device, the location information of the first device corresponding to the first environmental IoT device, the location information of the first environmental IoT device, and feedback information corresponding to the execution of the first service.

[0172] Wherein, the first device reports the location information of the first device, and the first device corresponds to the first environmental IoT device, so that the location information of the first device can be used by the third device to locate the first environmental IoT device.

[0173] Wherein, the information of the first environmental IoT device can be feedback information corresponding to the execution of the first service, and by reporting the feedback information, it means that the first environmental IoT device has been located.

[0174] Exemplarily, the second information can be forwarded to the third device by the second device, for example, the first device sends the second information to the second device, and the second device further forwards the second information to the third device. For example, the second information can be carried in a NAS message.

[0175] According to a communication method provided by the embodiment of the present application, the third device instructs the second device to request or trigger at least one first device to perform the first service for the first environmental IoT device, and the second device sends first information to the at least one first device, the first information indicating the request or trigger of the at least one first device to perform the first service, the first information being carried in a broadcast message, and the at least one first device sends information of the first environmental IoT device to the third device, so that the terminal reader can be reasonably selected as much as possible to complete the first service.

[0176] The above embodiment describes that the third device requests as many first devices as possible to complete the first service according to the capability information or subscription information of the first device and the first device that has established an RRC connection with the second device. The following embodiment will describe that the first device can also send its capability information or assistance information to the second device, and the second device sends a list of the first devices to the third device according to the capability information or subscription information of the first device and the first device that has established an RRC connection with the second device, so that the third device requests as many first devices as possible to complete the first service according to the list.

[0177] As shown in FIG. 5, it is a flowchart of a communication method provided by the embodiment of the present application. Exemplarily, the method can include the following steps:

[0178] S501. The first device sends third information to the second device.

[0179] Correspondingly, the second device receives the third information.

[0180] Exemplarily, the above first device can be a UE, and the second device can be an access network device. Here, the UE can be a reader or terminal reader.

[0181] The first device sends third information to the second device, the third information indicating the capability information or assistance information of the first device. Exemplarily, the third information indicates that the first device supports the first service, or indicates that the first device can perform the first service, or indicates that the first device expects to perform the first service. The first service is a positioning service, or the first service is used to obtain the position information of the first device, or the first service is used to obtain the position information of the first environmental IoT device, for example, used to obtain the position information of the environmental IoT device corresponding to the first device. Exemplarily, the third information indicating that the first device supports the first service can be understood as that the first device supports the communication with the environmental IoT device, or can be understood as that the first device supports as a reader.

[0182] Further, the third information also indicates the second frequency band corresponding to the first service supported by the first device.

[0183] It can be understood that the second device can also obtain the third information before performing the scheme of the embodiment, for example, the third information is configured to the second device by an OAM manner, or the third information is predefined by a protocol. Therefore, the step S501 is optional, which is represented by a dashed line in FIG. 5.

[0184] Further implementation of the third information can refer to the step S401 of the embodiment shown in FIG. 4, which is not described herein again.

[0185] S502. The third device sends fourth information to the second device.

[0186] Correspondingly, the second device receives the fourth information.

[0187] Exemplarily, the third device can send the fourth information to the second device in a case that the third device receives a request of a third party (for example, a server) or a UE to perform the first service and the like. The fourth information indicates that the second device requests or triggers the at least one first device to perform the first service on the first environmental Internet of Things device. The third device does not know which first devices exist under the second device, and the fourth information is blindly indicated to the second device.

[0188] Exemplarily, the third device can be a core network device.

[0189] It can be understood that the request or trigger of the second device to the at least one first device to perform the first service on the first environmental Internet of Things device does not necessarily come from the indication of the third device, for example, the request or trigger can also be determined by the second device itself. Therefore, the step S502 is optional, which is represented by a dashed line in FIG. 5.

[0190] Further implementation of the fourth information can refer to the step S402 of the embodiment shown in FIG. 4, which is not described herein again.

[0192] Correspondingly, the first device receives the first information.

[0193] Exemplarily, the second device sends the first information to the at least one first device after receiving the fourth information. The first information indicates that the at least one first device is requested or triggered to perform the first service, or the at least one first device is requested or triggered to perform the first service as a terminal reader.

[0198] It can be understood that the first device can also determine whether to perform the first service or whether to perform the first service according to other information. Therefore, step S504 is optional, which is represented by a dashed line in FIG. 5.

[0199] Specific implementation of step S504 can refer to step S404 of the embodiment shown in FIG. 4, which will not be repeated here.

[0200] S505. The first device sends information for establishing an RRC connection to the second device.

[0201] Correspondingly, the second device receives the information for establishing an RRC connection.

[0202] Exemplarily, the information for establishing an RRC connection includes a first cause value, and the first cause value indicates the first service.

[0203] Specific implementation of step S505 can refer to step S405 of the embodiment shown in FIG. 4, which will not be repeated here.

[0204] It can be understood that in the case that the first device is currently in an RRC connected state, the above steps S502-S505 can be skipped; in the case that the first device is currently in an RRC non-connected state, i.e., an RRC idle state or an RRC inactive state, the above steps S502-S505 need to be performed. Therefore, the above steps S502-S505 are optional, which are represented by a dashed line in FIG. 5.

[0205] If the first device is currently in an RRC non-connected state, after steps S502-S505 are performed, the first device enters a connected state, and the third information can be sent. At this time, S501 occurs after S505.

[0206] If the first device is currently in an RRC connected state, after S501 is performed, S506 is performed, and S502-S505 do not need to be performed.

[0207] S506. The second device sends fifth information to the third device.

[0208] Correspondingly, the third device receives the fifth information.

[0209] After the second device receives the information of establishing RRC connection sent by the first device, the second device determines at least one first device capable of performing the first service according to the first device having established the RRC connection and the capability information or the assistance information of the first device, and sends fifth information to the third device, where the fifth information indicates information of the at least one first device capable of performing the first service.

[0213] After the third device receives the fifth information, the third device determines the at least one first device that can perform the first service, and sends a first request to the at least one first device capable of performing the first service respectively. The first request is used to request the first environmental Internet of Things device to perform the first service, for example, to perform positioning on the first environmental Internet of Things device. The first request can include identification information of the first environmental Internet of Things device.

[0214] Exemplarily, the first request can be a first service request message, an inventory request or a positioning request.

[0215] The specific implementation of the step S507 can refer to the step S407 of the embodiment shown in FIG. 4, which will not be described here.

[0216] S508. The first device triggers the first environmental Internet of Things device to initiate access and report identification information of the first environmental Internet of Things device and / or position information of the first environmental Internet of Things device.

[0218] S509. The first device sends second information to the third device.

[0219] Correspondingly, the third device receives the second information.

[0220] After the first device successfully receives the first environmental IoT device access and the corresponding first environmental IoT device identification information and / or first environmental IoT device location information, the second information is sent to the third device. The second information indicates the first environmental IoT device information. For example, the first environmental IoT device information can include at least one of the following: first environmental IoT device identification information, first device location information corresponding to the first environmental IoT device, first environmental IoT device location information, and feedback information corresponding to the first service.

[0221] The specific implementation of this step S509 can refer to step S409 of the embodiment shown in FIG. 4, which will not be described here.

[0222] According to the communication method provided in the embodiment of the present application, the third device instructs the second device to request or trigger at least one first device to perform the first service on the first environmental IoT device, and the second device sends the first information to the at least one first device, where the first information indicates the request or trigger of the at least one first device to perform the first service, and the first information is carried in a broadcast message. The at least one first device sends the information of the first environmental IoT device to the third device, so that the terminal reader can be reasonably selected as much as possible to complete the first service.

[0223] The above embodiment describes that the third device instructs the second device to request or trigger at least one first device that has established an RRC connection to perform the first service on the first environmental IoT device. In the following embodiment, when the third device instructs the second device to request or trigger at least one first device to perform the first service on the first environmental IoT device, the at least one first device can be in an RRC connected state or in an RRC non-connected state.

[0224] As shown in FIG. 6, it is a flow diagram of another communication method provided in the embodiment of the present application. The method can include the following steps:

[0225] S601. The first device sends third information to the third device.

[0226] Correspondingly, the third device receives the third information.

[0227] For example, the above first device can be a UE, and the third device can be a core network device. Here, the UE can be a reader or terminal reader.

[0228] The third information indicates that the first device supports the first service, or indicates that the first device is capable of performing the first service, or indicates that the first device expects to perform the first service. The first service is a positioning service, or the first service is used to obtain position information of the first device, or the first service is used to obtain position information of the first environmental Internet of Things device, for example, to obtain position information of an environmental Internet of Things device corresponding to the first device. Illustratively, the third information indicates that the first device supports the first service, which can be understood as that the first device supports communication with the environmental Internet of Things device, or can be understood as that the first device supports being a reader.

[0229] Further, the third information also indicates that the first service supported by the first device corresponds to a second frequency band.

[0230] The specific implementation of step S601 can refer to step S401 shown in FIG. 4, which will not be repeated here.

[0231] It can be understood that the third device can also obtain the third information before performing the scheme of the embodiment, for example, the third device is configured with the third information by an OAM manner, or the third information is predefined by a protocol. Therefore, step S601 is optional, which is represented by a dashed line in FIG. 6.

[0232] S602. The third device sends fourth information to the second device.

[0233] Correspondingly, the second device receives the fourth information.

[0234] Illustratively, the second device can be an access network device.

[0235] Illustratively, the third device obtains the third information of at least one first device, so that the third device can send the fourth information to the second device corresponding to the at least one first device in the case of receiving a request of a third party (for example, a server) or a UE to perform the first service, etc. For example, the third device determines to send the fourth information to which second devices according to which second devices the first devices currently connect to or camp on, and sends the fourth information to the second devices. The fourth information indicates that the second device requests or triggers the at least one first device to perform the first service on the first environmental Internet of Things device.

[0236] It can be understood that the request or triggering of the second device to the at least one first device to perform the first service on the first environmental Internet of Things device does not necessarily come from the indication of the third device, for example, it can also be decided by the second device itself. Therefore, the step is optional, which is represented by a dashed line in FIG. 6.

[0237] The further implementation of the fourth information can refer to step S402 of the embodiment shown in FIG. 4, which will not be repeated here.

[0238] S603. The second device sends the first information to the first device.

[0239] Correspondingly, the first device receives the first information.

[0240] Exemplarily, after receiving the fourth information, the second device sends the first information to the at least one first device. The first information indicates a request or a trigger for the at least one first device to perform the first service.

[0241] The first information is carried in a broadcast message. Exemplarily, the broadcast message includes at least one of the following: scheduling information of a paging message, the paging message, system information.

[0242] Further, the first information also indicates a first frequency band corresponding to the first service.

[0243] For further implementation of the first information, reference can be made to step S403 of the embodiment shown in FIG. 4, which will not be repeated here.

[0244] S604. The first device determines that the first device can perform the first service based on at least one of the following: the first frequency band, the second frequency band, the power of the first device, and the service amount of the first device.

[0245] It can be understood that the first device can also determine whether to perform the first service or not according to other information. Therefore, step S604 is optional, which is represented by a dashed line in FIG. 6.

[0246] For specific implementation of step S604, reference can be made to step S404 of the embodiment shown in FIG. 4, which will not be repeated here.

[0247] S605. The first device triggers the first environmental IoT device to initiate access and report the identification information of the first environmental IoT device and / or the location information of the first environmental IoT device.

[0248] After receiving the first information, if the first device determines that the first device can perform the first service or determines to perform the first service, the first device triggers the first environmental IoT device to initiate access, for example, triggers the first environmental IoT device to initiate access of an A-IoT interface and report the identification information of the first environmental IoT device and / or the location information of the first environmental IoT device.

[0249] S606. The first device determines that the second information is acquired.

[0250] After performing step S605, the first device determines that the second information of the at least one first environmental IoT device is acquired, and then performs the subsequent steps.

[0251] If the first device does not successfully receive the first environmental IoT device access and the identification information of the first environmental IoT device and / or the location information of the first environmental IoT device, the first device does not need to report to the second device or the third device, and the process ends. If the first device is currently in an RRC non-connected state, the first device also does not need to establish an RRC connection with the second device. Therefore, steps S605-S607 are optional, and are represented by dashed lines in FIG. 6.

[0252] S607. The first device sends second information to the third device.

[0253] Correspondingly, the third device receives the second information.

[0254] After the first device successfully receives the first environmental IoT device access and the corresponding identification information of the first environmental IoT device and / or the location information of the first environmental IoT device, the first device sends second information to the third device. The second information indicates the information of the first environmental IoT device. For example, the information of the first environmental IoT device can include at least one of the following: the identification information of the first environmental IoT device, the location information of the first device corresponding to the first environmental IoT device, the location information of the first environmental IoT device, and feedback information corresponding to the execution of the first service.

[0255] The first device reports the location information of the first device, and the first device corresponds to the first environmental IoT device, so that the location information of the first device can be used by the third device to locate the first environmental IoT device.

[0256] The information of the first environmental IoT device includes feedback information corresponding to the execution of the first service by the first device, and by reporting the feedback information, it indicates that the first environmental IoT device has been located.

[0257] For example, if the first device is currently in an RRC non-connected state, the first device can first establish an RRC connection with the second device, and then send the above-mentioned second information to the second device or the third device. Alternatively, if the first device is currently in an RRC inactive state, the first device can send the above-mentioned second information to the second device or the third device through a small packet process.

[0258] For example, the second information can be forwarded to the third device through the second device, for example, the first device sends the second information to the second device, and the second device further forwards the second information to the third device. For example, the second information can be carried in a NAS message, or the second information is sent by the first device to the second device through an RRC message, and then sent by the second device to the third device through a next generation (NG) interface message.

[0259] According to the communication method provided in the embodiments of the present application, the third device instructs the second device to request or trigger at least one first device to perform the first service for the first environmental Internet of Things device, the second device sends first information to the at least one first device, the first information indicates the request or trigger of the at least one first device to perform the first service, the first information is carried in a broadcast message, and the at least one first device sends information of the first environmental Internet of Things device to the third device, so that the terminal reader can be reasonably and as much as possible selected to complete the first service; and after receiving the first information, if the first device is in an RRC non-connected state, the first device does not need to immediately establish an RRC connection with the second device, but can decide whether to establish an RRC connection after receiving the information of the first environmental Internet of Things device and the access of the first environmental Internet of Things device, so as to report the information of the first environmental Internet of Things device, and the power consumption and processing complexity of the first device due to the first service can be reduced as much as possible, and the signaling process is simplified.

[0260] It can be understood that the method and / or steps implemented by the first device in the above embodiments can also be implemented by a component (such as a chip or circuit) available for the first device; the method and / or steps implemented by the second device can also be implemented by a component (such as a chip or circuit) available for the second device; and the method and / or steps implemented by the third device can also be implemented by a component (such as a chip or circuit) available for the third device. When implemented by the components as described above, the receiving / sending can be understood as inputting / outputting, that is, the components communicate with other components of the first device, the second device and the third device. In addition, the method implemented by the first device can also be divided into being executed by a plurality of execution subjects, for example, divided into being executed by a plurality of components available for the first device; the method implemented by the second device can also be divided into being executed by a plurality of execution subjects, for example, divided into being executed by at least one of a CU, a DU, an RU and the like; and the method implemented by the third device can also be divided into being executed by a plurality of execution subjects, for example, divided into being executed by a plurality of components available for the third device.
