[0166] Terminal 101 can feature low memory, low processing power, low power consumption, small data transmission, and mass deployment capabilities. It can be maintenance-free and have a long service life; for example, the service life of A-IoT devices can exceed 10 years. A-IoT devices support ambient power, are powered by energy harvesting, and have no batteries or limited energy storage capacity (e.g., using capacitors). For example, A-IoT devices need to collect radio waves sent by network nodes to obtain energy before they can operate. Therefore, before obtaining energy, the environmental IoT device is usually in a "power-off" state, also known as an offline state. Therefore, the communication system 100 needs to support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to complete the data communication process as quickly as possible.

[0167] In some embodiments, the power acquisition and storage capabilities vary depending on the type and operating mode of the A-IoT device.

[0168] For example, environmental IoT devices can include the following types:

[0169] Device 1 or Device A: It has no energy storage capacity and cannot generate or amplify signals independently. Device 1 can communicate using backscattering.

[0170] Device 2a or Device B: It has energy storage capabilities but cannot generate signals independently. Device 2a can communicate using backscattering, and its stored energy can be used to amplify reflected signals.

[0171] Device 2b or Device C: It has energy storage capabilities and can generate signals independently, such as having active radio frequency (RF) components for transmission.

[0172] In some embodiments, the aim is to study a harmonized air interface design that minimizes the diversity of environmental IoT (if necessary), such as supporting devices with the following characteristics, or environmental IoT devices that can meet the following characteristics or constraints:

[0173] The peak power consumption is approximately 1 microwatt (μW), and it has energy storage capabilities. The initial sampling frequency offset (SFO) is as high as 10X ppm. The device does not support downlink (DL) signal amplification or uplink (UL) signal amplification. The UL signal transmission of this device requires backscattering on an externally provided carrier.

[0174] Peak power consumption ≤ several hundred μW, with energy storage function, SFO up to 10X ppm, and the device has DL signal and / or UL signal amplification functions. The UL signal transmission of this device can be generated internally or backscattered on an externally provided carrier. X can be determined by a protocol.

[0175] In some embodiments, network device 102 may include one or more network-side nodes or devices, or nodes or devices that assist in implementing network-side functions. Alternatively, network device 102 may include at least one of access network devices and core network devices.

[0176] In some examples, to support data transmission for A-IoT devices, network device 102 can implement one or more of the following functions:

[0177] Energy Source (ES) Function: Provides energy for environmental IoT devices, and can be used in devices 2a and 2b;

[0178] Downlink Transmission (DT) function: Triggers uplink transmission of IoT devices in the environment by sending indication information.

[0179] Continuous Wave (CW) Excitation Function: Provides the electromagnetic waves required for backscattering for environmental IoT devices. This can be used by Device 1 and Device 2a to achieve uplink transmission via backscattered CW. CW is actually a type of energy storage (ES), and environmental IoT devices can receive and store CW energy.

[0180] Uplink Receiver (UR) function: Receives uplink information backscattered by environmental IoT devices, or receives uplink information actively transmitted by environmental IoT devices.

[0181] The network device 102 can simultaneously perform multiple or all of the aforementioned functions; alternatively, the network device 102 includes multiple network nodes, each of which performs one of the functions. The network node performing each function can be a user equipment (UE), a repeater, or a base station, etc. When each network node performs a function, the network can coordinate or control the behavior of different nodes.

[0182] In some examples, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0183] In some examples, the technical solutions of this disclosure can be applied to the Open RAN architecture. 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.

[0184] In some examples, access network equipment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. The CU-DU structure can separate the protocol layer of the access network equipment. Some 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, which is centrally controlled by the CU. However, this is not the only example.

[0185] In some examples, a core network device can be a single device comprising one or more network elements, or it can be multiple devices or groups of devices, each comprising all or part of one or more network elements. Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0186] In some examples, core network equipment includes network elements with specific functions, such as Access Management Function (AMF) and Service Management Function (SMF).

[0187] In some embodiments, the UE includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0188] Figures 1B to 1F are schematic diagrams of the topology of a communication system according to embodiments of the present disclosure.

[0189] As shown in Topology 1 of Figure 1B, terminal 101 and network device 102 can communicate directly, directly receiving and transmitting DL and UL data. For example, network device 102 and terminal 101 directly interact with ambient IoT data or signaling.

[0190] As shown in Topology 2 in Figure 1C, terminal 101 and network device 102 indirectly receive and transmit DL and UL data, which are forwarded through intermediate node 103.

[0191] In some embodiments, the intermediate node 103 may be a relay, repeater, integrated access backhaul (IAB), or UE.

[0192] As shown in Figures 1D and 1E, in topology 3, terminal 101 and network device 102 indirectly receive and transmit DL and UL data. Then, there is an assisting node 104 on UL or DL, which is responsible for receiving or sending UL data or receiving DL data.

[0193] In some embodiments, the auxiliary node 104 may be a relay, repeater, IAB, or UE.

[0194] As shown in Topology 4 of Figure 1F, terminal 101 and UE105 directly receive and transmit DL and UL data; UE105 is responsible for collecting data and forwarding the collected data to the network side, such as network device 102.

[0195] In some embodiments, communication between terminal 101 and network device 102, such as communication based on topology 1 and topology 2, can utilize spectrum resources in three forms: in-band, guard band, and stand-alone. In-band uses normal NR communication DL and / or UL spectrum resources, such as the spectrum resources used for DL / UL communication between the base station and other UEs (Figure 1B), or the spectrum resources for DL / UL communication between the UE and the base station (Figure 1C). Guard band uses the spectrum resources of the guard band of normal NR communication DL and / or UL spectrum. Stand-alone uses spectrum resources unrelated to NR communication.

[0196] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in 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 this disclosure are also applicable to similar technical problems.

[0197] The following embodiments of this disclosure can be applied to the communication system 100 shown in Figures 1A to 1F, or to some of the main bodies, but are not limited thereto. The main bodies shown in Figures 1A to 1F are illustrative. The communication system may include all or some of the main bodies in Figures 1A to 1F, or it may include other main bodies outside of Figures 1A to 1F. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0198] 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).

[0199] In some implementations, traditional IoT devices are typically powered by batteries with limited lifespans. With the proliferation of IoT networks and the large number of IoT devices, issues such as battery maintenance, recycling, and replacement have become increasingly serious. Batteries that cannot be successfully recycled can also have harmful impacts on the ecosystem and environment. Therefore, environmentally friendly and secure battery-free communication has emerged. Battery-free communication can improve network performance and sustainability, expand application scenarios, and significantly reduce device size and cost.

[0200] In some implementations of 5G communication technology, existing low-power wide-area (LPMA) technologies, such as machine-type communication (MTC), narrowband Internet of Things (NB-IoT), and reduced capability (RedCap), can meet the growing demands of vertical industries, enabling low cost, low power consumption, and massive connectivity. However, they still cannot address the following needs: First, devices powered by traditional batteries are unsuitable, for example, under extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, humid environments); second, maintenance-free devices are required (e.g., traditional batteries that do not require replacement); and finally, ultra-low complexity, very small device size or form factor (e.g., thickness in millimeters), and longer lifespan are required. IoT that supports ambient power or environmentally powered systems can meet these needs.

[0201] In some implementations, low-power IoT communication chips such as Bluetooth Low Energy (BLE) Long Range Radio (LoRa) or NB-IoT consume tens or even hundreds of milliwatts of power for transmission and reception. However, as described in the preceding embodiments, environmental energy harvesting yields only microwatts of energy. Harvesting energy from the environment to power sensing nodes such as terminal 101 for data transmission and wireless communication requires wireless communication technologies that can reduce communication power consumption to tens or even less than ten microwatts, such as backscatter communications.

[0202] In some implementations, backscatter communication is an extremely low-power modulation and transmission technology that utilizes the principle of radio frequency signal backscattering, serving as a means to achieve the Internet of Things (IoT). In backscatter communication, because a portion of the radio frequency signal, such as electromagnetic waves, is reflected when it reaches the surface of an object, a passive node, such as terminal 101, adjusts the matching between its receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal. It then modulates the sensed data it acquires onto the reflected signal, completing the data transmission. Compared to other communication technologies, backscatter communication eliminates the need for complex radio frequency structures, reducing the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also eliminates the need for complex baseband processing, thus simplifying terminal design and significantly reducing terminal node costs.

[0203] In some implementations, in a Radio Frequency Identification (RFID) system using backscatter communication, as shown in Figure 1G, the receiver sends a radio frequency excitation signal to activate a passive node. The receiver, for example, is an RFID reader, corresponding to network device 102; the passive node, for example, is an RFID tag, corresponding to terminal 101. The tag uses backscatter communication to modulate its own information onto the radio frequency signal. The reader receives the reflected signal from the passive tag and demodulates it to achieve information transmission. RFID communication suffers from the following drawbacks: the wireless signal experiences double-path fading, resulting in significant path loss, short effective communication distance, and therefore limited coverage; it also requires single-channel transmission; strict tag alignment is required; and there is no power control. Therefore, it is necessary to integrate 3GPP communication technologies to improve the wireless communication performance of RFID technology in passive Internet of Things (IoT) applications.

[0204] In some implementations of an RFID communication system, as shown in Figure 1H, commands are functionally categorized into three types: tag selection, inventory, and access. Selection commands include the Select command and the Challenge command. Inventory commands include the Query command, QueryAdjust command, QueryRep command, ACK command, and NAK command. Access commands include the Req_RN command, Read command, Write command, Kill command, and Lock command; optionally, they may also include the Access command, BlockWrite command, and BlockErase command.

[0205] The following is an application example of disk storage and retrieval, illustrated in Figure 1I. The command application example in disk storage and retrieval may include the following steps:

[0206] (1) After receiving a valid Query command, each tag that meets the set criteria and is selected generates a random number. Each tag with a random number of zero will generate an echo, such as sending back a temporary password RN16, which is a 16-bit random number, and will move to the Reply state; other tags can change certain attributes and flags to exit the group of tags with zero, which helps to reduce duplicate identification.

[0207] (2) After receiving a valid QueryAdjust command, each tag generates a new random number, and other behaviors are the same as the Query command.

[0208] (3) After a tag receives a valid QueryRep command, the original random number of each tag in the tag group is decremented by one, and other behaviors are the same as the Query command.

[0209] (4) Only unique tags can receive a valid ACK command. Upon receiving the ACK command, the tag will send back the contents of the EPC area according to the Electronic Product Code (EPC) communication protocol. The ACK command can use either RN16 or Handle, where Handle is a temporary 16-bit random number representing the tag's identity.

[0210] (5) After receiving a valid NAK command, tags in the Ready and Killed states retain their original states, while tags in other states transition to the Arbitrate state. The different states of a tag are shown in Figure 1H.

[0211] In some implementations, the Ambient IoT system includes the following service types:

[0212] DT data transmission, where DT indicates that data transmission terminates at the IoT device, such as the terminal, meaning that the reception or processing of data is ultimately completed at the IoT device itself.

[0213] DO-DTT data transmission can be triggered by network devices to initiate data transmission from IoT devices such as terminals;

[0214] DO data transmission includes DO-A, which means that IoT devices, such as terminals, actively send data to the network based on their own status or preset conditions. For example, based on sensor data, the sensor and the terminal may be independent, but have a communication or connection relationship.

[0215] In some implementations, only DT services and DO-DTT services are supported in version 19 (R19). For DO-DTT services, the network can trigger the terminal to initiate an access procedure, supporting a three-step random access procedure, as shown in the interaction diagrams of random access in Figures 1J and 1K.

[0216] As shown in Figure 1J, in an inventory-only scenario, the random access process may include the following steps:

[0217] Step S1101: The reader sends a paging message to the device.

[0218] Step S1102, the terminal sends MSG1 to the reader, MSG1 includes RN16;

[0219] In step S1103, the reader sends MSG2 to the terminal, MSG2 including RN16 for contention resolution;

[0220] Step S1104: The terminal sends MSG3 to the reader. MSG3 includes the device ID, RN16, or access stratum identifier (AS-ID).

[0221] In step S1105, the reader sends MSG4 to the terminal, which includes a negative acknowledgment (NACK) response. This step is optional.

[0222] As shown in Figure 1K, in a scenario involving inventory and commands, the random access process may include the following steps:

[0223] Step S1201: The reader sends a paging message to the device.

[0224] Step S1202: The terminal sends MSG1 to the reader, MSG1 including RN16;

[0225] Step S1203: The reader sends MSG2 to the terminal, MSG2 including RN16 for conflict resolution;

[0226] Step S1204: The terminal sends MSG3 to the reader. MSG3 includes Device ID, RN16, or AS-ID.

[0227] In step S1205, the reader sends MSG4 to the terminal. MSG4 includes a Reader To Device (R2D) instruction.

[0228] Step S1206: The terminal sends a Device To Reader (R2D) response to the reader.

[0229] In some implementations, for DO-A type services (hereinafter referred to as DO-A services), the terminal can generate and transmit signals autonomously, only needing to transmit signals on the selected UL resources. However, DO-A services may coexist or conflict with other services. For example, different services at the same time or frequency domain location may have conflicting transmission resource requirements. Ensuring that resource selection does not conflict during data transmission and using appropriate UL power to avoid uplink interference are problems that need to be solved.

[0230] Figure 2A is an interactive schematic diagram illustrating a processing method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a processing method, which includes:

[0231] In step S2101, network device 102 sends first information to terminal 101.

[0232] In some embodiments, terminal 101 receives first information sent by network device 102.

[0233] In some embodiments, network device 102 may include a reader, or an access network device, or a relay UE, or a node device that can implement one or more of the following functions: ES function, DT function, CW activation function, or UR function.

[0234] In some embodiments, terminal 101 may include an A-IoT device, or simply a device, or may include a tag.

[0235] In some embodiments, the first information is used to instruct the terminal 101 to perform a first environment IoT service and / or a second environment IoT service.

[0236] Optionally, the first information may explicitly indicate the service performed by terminal 101. For example, by using 1 bit in the first information, a value of 1 indicates the performance of a first environment IoT service, a value of 0 indicates the performance of a second environment IoT service, and a bit set to reserved (R) indicates the performance of both services.

[0237] Optionally, the first information may implicitly indicate the service to be performed by terminal 101. For example, the first information may carry resources corresponding to the IoT service in the first environment, thereby implicitly indicating the execution of the IoT service in the first environment. Alternatively, the first information may carry priority indications for two services, implicitly indicating the execution of the service with the higher priority.

[0238] In some embodiments, when the first environment IoT service and the second environment IoT service occur concurrently (parallel), the network device 102 sends first information to the terminal 101.

[0239] Optionally, the concurrent occurrence of the first and second environment IoT services can be replaced by the following: the first and second environment IoT services conflict, or the first and second environment IoT services exist simultaneously, or the first and second environment IoT services coexist, or both the first and second environment IoT services need to be executed, or there are business requirements for both the first and second environment IoT services. In these cases, concurrency, conflict, or coexistence can refer to the first and second environment IoT services occurring concurrently, conflicting, or coexisting within a single point in time, a single time window, or a single time period.

[0240] Optionally, the concurrent occurrence or conflict of the first environment IoT service and the second environment IoT service can be that the first environment IoT service and the second environment IoT service occur at the same time domain location and / or frequency domain location. Here, the time domain location can be a time window or a point in time, and the frequency domain location can be a frequency point or a frequency range.

[0241] Optionally, the concurrent operation or conflict between the first environment IoT service and the second environment IoT service can occur when network device 102 identifies the first environment IoT service during the execution of the second environment IoT service. Optionally, at this time, the second environment IoT service may not have completed the transmission of all service data.

[0242] In some embodiments, network device 102 can determine whether the first environment IoT service and the second environment IoT service are concurrent based on the first signaling sent by terminal 101.

[0243] Optionally, the first signaling may refer to the first signaling or information sent by terminal 101 to network device 102. For example, before step S2101, terminal 101 sends the first signaling to network device 102. This signaling may directly or indirectly instruct terminal 101 to request the execution of a service.

[0244] Optionally, during the execution of the second environment IoT service, if network device 102 receives a first signaling message from terminal 101 indicating that the requested service is the first environment IoT service, network device 102 can determine that the first environment IoT service and the second environment IoT service are concurrent or conflicting. In this case, network device 102 can send first information to terminal 101.

[0245] In some embodiments, the first environmental IoT service and the second environmental IoT service represent different environmental IoT services.

[0246] Optionally, the IoT business in the first environment is a DO-A business, and the IoT business in the second environment is a DT business or a DO-DTT business.

[0247] In one embodiment, the terminal executing the second environment IoT service and the terminal executing (or requesting to execute) the first environment IoT service can be the same terminal, and the network device 102 sends the first information to the terminal.

[0248] In one example, when network device 102 and terminal 101 are communicating based on DT service or DO-DTT service, when network device 102 receives the first signaling sent by terminal 101 triggered by DO-A service, network device 102 determines that DT service or DO-DTT service and DO-A service are concurrent, and network device 102 can send the first information to terminal 101.

[0249] In this embodiment, the same terminal 101 can execute different types of environmental IoT services.

[0250] In another embodiment, the terminal executing the second environment IoT service and the terminal triggering the first environment IoT service can be different terminals. The network device 102 can send first information to the terminal executing the second environment IoT service and the terminal executing (or requesting to execute) the second environment IoT service, respectively.

[0251] In one example, when network device 102 receives a first signaling message triggered by DO-A service from a second terminal during communication between network device 102 and the first terminal based on DT service or DO-DTT service, network device 102 determines that DT service or DO-DTT service and DO-A service are concurrent. Network device 102 can then send first information to the first terminal and the second terminal respectively.

[0252] In this embodiment, different types of environmental IoT services can be executed through different terminals 101, such as one terminal 101 executing one type of environmental IoT service.

[0253] In some embodiments, if the first environment IoT service and the second environment IoT service do not support simultaneous execution or coexistence, the first information is used to instruct the execution of the first environment IoT service, wherein the first environment IoT service has a higher priority than the second environment IoT service.

[0254] Optionally, DO-A services have a higher priority than DO-DTT services.

[0255] Optionally, the first environment IoT service and the second environment IoT service do not support simultaneous execution or coexistence. This may mean that the same terminal does not support the ability to execute two services at the same time, or that the network device cannot execute two services at the same time with the same or different terminals, or that the two services may experience data loss or corruption in concurrent or conflicting scenarios.

[0256] In some embodiments, the first message is a paging message or other message.

[0257] Optionally, the first information can be a paging message for IoT services in the first environment, such as DO-A services.

[0258] Optionally, the first information can be a paging message for IoT services in the second environment, such as DT services or DO-DTT services.

[0259] Optionally, the first information can be a paging message for both a first-environment IoT service and a second-environment IoT service. For example, the first information can be a paging message repeatedly sent by network device 102 during communication based on the second-environment IoT service.

[0260] Optionally, when the terminal performing the first environment IoT service and the second environment IoT service is the same terminal, the network device 102 can send a paging message to the terminal, which can be a paging message for the first environment IoT service and the second environment IoT service.

[0261] Optionally, when the terminals performing the first environment IoT service and the second environment IoT service are different terminals, in conjunction with the description of the above embodiments, the network device 102 can send a paging message to the first terminal for the second environment IoT service such as DT service or DO-DTT service, and send a paging message to the second terminal for the first environment IoT service such as DO-A service.

[0262] In some embodiments, the first information includes at least one of the following:

[0263] The first instruction information is used to instruct the terminal corresponding to the IoT service in the first environment to perform random access;

[0264] The second instruction information is used to instruct the suspension or termination of IoT services in the second environment;

[0265] The third indication information is used to indicate whether the first information is a duplicate transmission.

[0266] Optionally, the first indication information can be IoT service indication information for a first environment, such as DO-A service indication information (DO-Aindication). In one example, the first indication information includes a paging ID, which is used to instruct the terminal corresponding to the IoT service in the first environment to perform random access. The terminal triggered by the IoT service in the first environment accesses the network according to the first indication information. Different IoT services in the first environment can correspond to different paging IDs.

[0267] Optionally, the second indication information may be a service suspension indication information or a service stop indication information, used to indicate the suspension or stop of the currently executing second environment IoT service, such as DT service or DO-DTT service, and the terminal executing the service suspends or stops the second environment IoT service according to the second indication information.

[0268] Optionally, the third indication information can be an information identifier or a service identifier (Transaction ID), used to indicate whether the first information is a duplicate transmission. For example, if the first information is a paging message, the service identifier can be used to indicate whether the paging message is a duplicate transmission. The terminal determines whether to respond to the paging message based on the third indication information. Furthermore, the service identifier can identify an IoT service for a period of time.

[0269] In one example, when the terminal executing the second environment IoT service and the terminal executing the first environment IoT service are the same terminal, the network device 102 sends first information to that terminal. The first information is a paging message for both the first and second environment IoT services. For example, the first information may include first indication information and second indication information, or the first information may include first indication information, second indication information, and third indication information.

[0270] In another example, when the terminal executing the second environment IoT service and the terminal executing the first environment IoT service are different terminals, in conjunction with the description of the above embodiments, the network device 102 sends first information to the terminal executing (requesting to execute) the first environment IoT service, such as the second terminal. The first information may be a paging message for the first environment IoT service, such as the DO-A service. For example, the first information includes first indication information and / or third indication information. The network device 102 may also send first information to the terminal executing the second environment IoT service, such as the first terminal. The first information may be a paging message for the second environment IoT service, such as the DT service or the DO-DTT service. For example, the first information includes second indication information and / or third indication information.

[0271] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0272] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0273] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0274] In step S2102, network device 102 and terminal 101 suspend or stop communication based on IoT services in the second environment.

[0275] In some embodiments, when the terminal executing the second environment IoT service and the terminal executing (or requesting to execute) the first environment IoT service are the same terminal, then terminal 101 in this step refers to that same terminal. After receiving the first information, if the first information includes at least the first instruction information and the second instruction information, terminal 101 stops or suspends communication based on the second environment IoT service.

[0276] In some embodiments, when the terminal executing the second environmental IoT service and the terminal executing (or requesting to execute) the first environmental IoT service are different terminals, the terminal 101 in this step is the terminal executing the second environmental IoT service, such as the first terminal. After receiving the first information, if the first information includes second indication information and / or third indication information, the first terminal can stop or suspend communication based on the second environmental IoT service according to the first information.

[0277] In some embodiments, if the terminal 101 determines to stop communication of the second environment IoT service in this step, the method may further include the following steps: S2102-11, the terminal 101 clears the relevant information of the second environment IoT service.

[0278] In this step, relevant information about the IoT business in the second environment, such as business identifiers, is collected.

[0279] In some embodiments, if the terminal 101 determines to suspend communication of the second environment IoT service in this step, the method may further include the following steps: S2102-21, the terminal 101 enters a state waiting for re-access to be triggered.

[0280] In this step, if the terminal needs to re-execute the second environment IoT service or is instructed by the network device to do so, the terminal can initiate a random access to the network device 102 as described in the above three-step random access process, as shown in Figure 1J or Figure 1K, and re-establish a communication connection with the network device 102 based on the second environment IoT service.

[0281] In step S2103, terminal 101 initiates a random access procedure to network device 102 (for IoT services in the first environment).

[0282] In some embodiments, when the first environment IoT service and the second environment IoT service do not support simultaneous execution or coexistence, the terminal 101 determines the service to be executed based on the received first information.

[0283] Optionally, when the terminal executing the second environment IoT service and the terminal executing (or requesting to execute) the first environment IoT service are the same terminal, then terminal 101 in this step refers to that same terminal. After receiving the first information, if the first information includes at least first indication information and second indication information, terminal 101 can execute the first environment IoT service with higher priority, such as the DO-A service, according to the first information.

[0284] Optionally, when the terminal executing the second environmental IoT service and the terminal executing (or requesting execution) the first environmental IoT service are different terminals, the terminal 101 in this step is the terminal executing (or requesting execution) the first environmental IoT service, such as the second terminal. After receiving the first information, if the first information includes first indication information and / or third indication information, the second terminal can execute the first environmental IoT service with higher priority, such as the DO-A service, according to the first information.

[0285] In some embodiments, the random access procedure is a three-step contention-based (CB) random access procedure: terminal 101 sends MSG1 to network device 102; after receiving MSG1, network device 102 sends MSG2 to terminal 101; after receiving MSG2, terminal 101 sends MSG3 to network device 102. Optionally, network device 102 may also send MSG4.

[0286] Optionally, MSG1 is used to request the establishment of a connection based on IoT services such as DO-A services in the first environment. The content of the information in the above random access process can be seen in Figure 1J or Figure 1K.

[0287] Optionally, MSG1 may carry a terminal identifier, such as RN16. Specifically, for MSG1 of DO-A service, an RN16 may be randomly selected from the range of RN16 reserved in the protocol; or, for MSG1 of DO-A service, the terminal may randomly generate an RN16.

[0288] Alternatively, the content of MSG3 can be found in the implementation of step S2204 in Figure 2B.

[0289] In some embodiments, terminal 101 and network device 102 establish a connection based on a random access procedure.

[0290] In step S2104, network device 102 and terminal 101 transmit data of the first environment IoT service.

[0291] In some embodiments, after the terminal 101 and the network device 102 establish a connection based on the first environment IoT service, they can communicate based on the first environment IoT service and transmit the data of the first environment IoT service.

[0292] For example, after the terminal 101 establishes a connection with the network device 102 in step S2103, it can transmit service data of IoT services in the first environment, such as DO-A services.

[0293] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, steps S2101 to S2102 may be implemented as independent embodiments, and steps S2101, S2103 and S2104 may be implemented as independent embodiments, but are not limited thereto.

[0294] In some embodiments, steps S2102 and S2103 may be performed in an alternate order or simultaneously.

[0295] In some embodiments, steps S2102, S2103, and S2104 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0296] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0297] Figure 2B is an interactive schematic diagram illustrating a processing method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a processing method, which includes:

[0298] In step S2201, network device 102 sends first information to terminal 101.

[0299] In some embodiments, the description of network device 102 and terminal 101 in step S2201 can be found in the implementation of step S2101 in FIG2A.

[0300] In some embodiments, the timing of the network device 102 sending the first information in step S2201 (such as when concurrent services occur) can be referred to the implementation of step S2101 in Figure 2A.

[0301] In some embodiments, the method by which the network device 102 determines whether the first environment IoT service and the second environment IoT service are concurrent or conflicting in step S2201 can be found in the implementation of step S2101 in Figure 2A.

[0302] In some embodiments, the specific service types of the first environment IoT service and the second environment IoT service in step S2201 can be found in the implementation of step S2101 in Figure 2A.

[0303] In some embodiments, the terminal situation for performing IoT services in different environments in step S2201 can be seen in the implementation of step S2101 in Figure 2A.

[0304] In some embodiments, the difference between step S2201 and step S2101 in this disclosure is that the first environment IoT service and the second environment IoT service in this disclosure support simultaneous execution or coexistence, and the content of the first information may differ.

[0305] In some embodiments, where the first environment IoT service and the second environment IoT service can be executed simultaneously, the first information can be used to instruct the execution of the first environment IoT service and the second environment IoT service.

[0306] In some embodiments, in scenarios where the first environment IoT service and the second environment IoT service can be executed simultaneously, if the network device 102 detects that different services are concurrent or conflicting, such as when the network device 102 and the terminal 101 are performing the second environment IoT service, and the network device 102 detects the first environment IoT service, the network device 102 can terminate the communication of the second environment IoT service first, such as terminating the communication of the second environment IoT service based on the first information instruction.

[0307] Optionally, the execution terminal for the first environment IoT service and the second environment IoT service is the same. The network device 102 can send first information to the terminal and terminate the communication with the terminal 101 based on the second environment IoT service.

[0308] Optionally, the execution terminals of the first environment IoT service and the second environment IoT service are different terminals. In conjunction with the description of the foregoing embodiments, the network device 102 can send first information to the first terminal and terminate the communication with the first terminal based on the second environment IoT service.

[0309] In some embodiments, the first information is used to instruct the terminal 101 corresponding to the IoT service in the first environment to perform random access.

[0310] In this embodiment, in a scenario where the first environment IoT service and the second environment IoT service support simultaneous execution, if the network device 102 identifies that different services are concurrent or conflicting, the network device 102 can send first information to the terminal 101 corresponding to the first environment IoT service.

[0311] Optionally, the execution terminal for the first environment IoT service and the second environment IoT service is the same. The network device 102 can send first information to the terminal to indicate that communication based on the second environment IoT service should be terminated first, and to indicate that the terminal can access the network based on the first environment IoT service.

[0312] Optionally, the execution terminals of the first environment IoT service and the second environment IoT service are different terminals. In conjunction with the description of the foregoing embodiments, the network device 102 can send first information to the first terminal to terminate communication with the first terminal based on the second environment IoT service; and can send first information to the second terminal to instruct the second terminal to access the network based on the first environment IoT service.

[0313] In some embodiments, the first information is a repeatedly sent paging message.

[0314] Optionally, the first message is a paging message for a second-environment IoT service, such as DT service or DO-DTT service, that is repeatedly sent.

[0315] Optionally, if network device 102 and terminal 101 are performing a second environment IoT service, and network device 102 has already sent a paging message for the second environment IoT service, in the environment IoT, network device 102 can repeatedly send paging messages to allow more devices to connect. The first information can be the repeatedly sent paging message.

[0316] Optionally, network device 102 may send first information to terminals of the first environment IoT service and terminals of the second environment IoT service (which may be the same terminal or different terminals).

[0317] Optionally, for the terminal receiving the first information in the first environment IoT service, the terminal identifier (device id) and other related identification information in the repeatedly sent paging messages can be ignored.

[0318] In some embodiments, the first information includes at least one of the following:

[0319] The fourth indication information is used to indicate that the terminal corresponding to the IoT service in the first environment can make random access;

[0320] The fifth indication information is used to indicate the random access resources of the terminal corresponding to the IoT service in the first environment. The random access resources include one or more of the following: time domain resources, frequency domain resources, and preamble resources.

[0321] Optionally, the fourth indication information can be IoT service indication information in the first environment, such as DO-A service indication information, which indicates that the terminal that triggers the DO-A service can access the network randomly, and the terminal that triggers the DO-A service accesses the network based on the DO-A service according to the fourth indication information.

[0322] Optionally, the fifth indication information can be configuration information, used to configure the random access resources for IoT services in the first environment, such as DO-A services.

[0323] In one example, the fifth indication information is used to indicate that the time domain resource of the DO-A service is located in the first time domain unit after the first information is received. The time domain unit can refer to a time slot, symbol, or millisecond, etc. For example, the fifth indication information is used to indicate that the time domain resource of the DO-A service is located in the first time slot after the first information is received.

[0324] In step S2202, terminal 101 sends MSG1 to network device 102.

[0325] In some embodiments, network device 102 receives MSG1 sent by terminal 101.

[0326] In some embodiments, MSG1 is used to indicate a random access procedure triggered by an IoT service in a first environment, and / or, MSG1 is used to indicate a random access procedure triggered by an IoT service in a second environment.

[0327] Optionally, the terminal 101 corresponding to the first environment IoT service can request a random access procedure based on the first environment IoT service via MSG1. For example, when network device 102 identifies the first environment IoT service such as DO-A during communication with terminal 101 based on a second environment IoT service such as DO-DTT, after receiving the first information sent by network device 102, the terminal 101 corresponding to the first environment IoT service can send MSG1 to request the establishment of random access for the first environment IoT service.

[0328] Optionally, the terminal 101 corresponding to the second environment IoT service can request or re-request the random access procedure for the second environment IoT service via MSG1. For example, when network device 102 identifies the first environment IoT service during communication with terminal 101 based on the second environment IoT service, after receiving the first information sent by network device 102, the terminal 101 corresponding to the second environment IoT service can send MSG1 to request the establishment of a re-access procedure or request an initial access procedure for the second environment IoT service, or in other words, a new random access procedure.

[0329] In some embodiments, the MSG1 received by the network device includes a terminal identifier, which is one of a plurality of identifiers defined by the protocol or generated by the terminal.

[0330] Optionally, the terminal identifier is RN16, and MSG1 includes an RN16 randomly selected by terminal 101 from a plurality of RN16 reserved by the system or defined by the protocol, or an RN16 randomly generated by terminal 101.

[0331] Optionally, for the MSG1 used in the first environment IoT service such as DO-A service, an RN16 can be randomly selected from the range of RN16 reserved in the protocol; or, for the MSG1 of DO-A service, if the protocol or system does not reserve an RN16 for DO-A service, the terminal can randomly generate an RN16.

[0332] In some embodiments, terminal 101 sends MSG1 to network device 102 based on random access resources such as time-frequency resources or preamble resources in the first information.

[0333] Optionally, MSG1 includes the preamble resource from the first information.

[0334] Optionally, terminal 101 sends MSG1 to network device 102 on the time domain resources in the first information.

[0335] In one example, for a first-environment IoT service such as DO-A service, terminal 101 sends MSG1 for DO-A service to network device 102 in the first time domain unit, such as the first time slot, after the first information reception time.

[0336] In this example, network device 102 receives MSG1 sent by terminal 101 in the first time domain unit after the reception time of the first information.

[0337] In some embodiments, the time-frequency resources or preamble resources of MSG1 are used to indicate the service type.

[0338] In this embodiment, the service types include first-environment IoT services and second-environment IoT services. Different time-domain resources or preamble resources can correspond to different service types. For example, MSG1 sent by terminal 101 in the first time slot after the reception time of the first information corresponds to a first-environment IoT service such as DO-A service.

[0339] In step S2203, network device 102 sends MSG2 to terminal 101.

[0340] In some embodiments, terminal 101 receives MSG2 sent by network device 102.

[0341] Alternatively, the information content of MSG2 can be referenced to the embodiments in Figure 1J or Figure 1K.

[0342] In step S2204, terminal 101 sends MSG3 to network device 102.

[0343] In some embodiments, network device 102 receives MSG3 sent by terminal 101.

[0344] Optionally, the terminal 101 corresponding to the IoT service in the first environment and the terminal 101 corresponding to the IoT service in the second environment (the two terminals may be the same or different) can send MSG3 respectively.

[0345] In some embodiments, MSG3 includes indication information for random access.

[0346] In some embodiments, the indication information is used to indicate at least one of the following:

[0347] The random access reason is triggered by IoT services in the first environment;

[0348] The amount of data reported by the First Environment IoT business.

[0349] Optionally, the indication information is used to indicate the reason for random access. This embodiment of the disclosure takes the MSG3 sent by the terminal 101 of the first environment IoT service as an example for description. The reason for random access may include the first environment IoT service such as DO-A service trigger.

[0350] Optionally, the indication information can be data volume indication information, used to indicate the amount of data reported by the first environment IoT service, such as DO-A service. For example, it can indicate whether the amount of data reported by the first environment IoT service exceeds a data volume threshold, or indicate the range of values ​​for the amount of data reported by the first environment IoT service.

[0351] In one example, the indication information occupies one bit. The value of this bit is used to indicate whether the amount of data to be transmitted by the first environment IoT service is greater than the data amount threshold. For example, when the value of this bit is the first value, it indicates that the amount of data to be transmitted by the first environment IoT service is greater than the data amount threshold. When the value of this bit is the second value, it indicates that the amount of data to be transmitted by the first environment IoT service is less than or equal to the data amount threshold. The first value is 1 and the second value is 0, or the first value is 0 and the second value is 1.

[0352] In one example, the indication information occupies multiple bits, corresponding to multiple values. For example, when it occupies 3 bits, the indication information corresponds to 8 values, and each value corresponds to a range of data values.

[0353] Optionally, the data volume threshold or the data volume range corresponding to different values ​​can be defined by the protocol or predefined by the system, or it can be configured by the network device 102. For example, the data volume threshold or the data volume range corresponding to different values ​​can be included in the paging message sent by the network device 102 to the terminal 101 or in the configuration information sent separately.

[0354] In step S2205, network device 102 and terminal 101 transmit data of the first environment IoT service and the second environment IoT service.

[0355] In some embodiments, after the terminal 101, triggered by the first environment IoT service, sends MSG3 to the network device 102, other steps of the CB-based 3-step random access process may be included, such as executing steps S1105 or S1205 to S1206 as shown in FIG1J or FIG1K, to establish a communication connection with the network device 102 based on the first environment IoT service.

[0356] In some embodiments, after the terminal 101 and the network device 102 establish a connection based on a first environment IoT service, and after establishing or reconnecting to a second environment IoT service, they can transmit service data of the first environment IoT service, such as DO-A service, and service data of the second environment IoT service, such as DO-DTT service.

[0357] Optionally, if the terminals corresponding to the two services are the same, the network device 102 can transmit the two service data with the terminal 101, and the two service data can correspond to their respective time and frequency resources.

[0358] Optionally, if the terminals corresponding to the two services are different terminals, the network device 102 can transmit data of the second environment IoT service such as DO-DTT with the first terminal and transmit data of the first environment IoT service such as DO-A service with the second terminal. The two terminals can transmit data on the corresponding time and frequency resources.

[0359] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2205. For example, step S2201 may be implemented as a standalone embodiment, steps S2201 and S2202 may be implemented as standalone embodiments, and steps S2201 to S2204 may be implemented as standalone embodiments, but are not limited thereto.

[0382] In some embodiments, after receiving MSG1 sent by terminal 101, network device 102 sends first information to terminal 101.

[0383] In some embodiments, the first information is MSG2, which is used to indicate the access information corresponding to the IoT service in the first environment, such as the access information corresponding to the DO-A service.

[0419] In some embodiments, the difference between step S2402 and step S2101 in this disclosure is that the first environment IoT service and the second environment IoT service in this disclosure support simultaneous execution or coexistence, and the first information can be used to instruct the terminal corresponding to the first environment IoT service to perform random access.

[0420] In some embodiments, the first information may be a paging message.

[0421] In some embodiments, the first information may be a dedicated message or synchronization signal for IoT services in a first environment.

[0422] In step S2403, terminal 101 sends MSG1 to network device 102 on the first frequency domain resources and / or the first time domain resources.

[0426] In one example, network device 102 sends first information to terminal 101, such as a message or synchronization signal specific to a first environment IoT service. This first information is used to indicate first frequency domain resources and / or first time domain resources. For example, time domain resources after the time the first information is received are all considered first time domain resources.

[0427] In some embodiments, the first frequency domain resource may be the same as or different from the second frequency domain resource.

[0428] In one example, the resources of the first environment IoT service and the second environment IoT service are frequency-division multiplexed, and the first frequency domain resources are different from the second frequency domain resources.

[0429] In some embodiments, the first time-domain resource may be the same as or different from the second time-domain resource.

[0430] In one example, resources for the first environment IoT service and the second environment IoT service are time-division multiplexed, with the first time-domain resources being different from the second time-domain resources. For instance, time-domain resources after the first information reception time are all first time-domain resources.

[0431] In another example, the first frequency domain resource is different from the second frequency domain resource, and / or the first time domain resource is different from the second time domain resource.

[0432] In step S2404, network device 102 sends MSG2 to terminal 101.

[0433] In some embodiments, the terminal receives MSG2, which may include RAR.

[0434] In step S2405, terminal 101 sends MSG3 to network device 102.

[0435] In some embodiments, MSG3 may be transmitted on a first frequency domain resource and / or a first time domain resource.

[0436] In some embodiments, the content of MSG3 can be found in the implementation of step S2204 in Figure 2B.

[0437] In some embodiments, network device 102 may send MSG4 after receiving MSG3.

[0438] In step S2406, network device 102 and terminal 101 transmit data of the first environment IoT service.

[0439] In some embodiments, the first environment IoT services are performed on the first frequency domain resources and / or the first time domain resources, such as the transmission of service data on the first frequency domain resources and / or the first time domain resources.

[0440] Optionally, the description of step S2406 can also refer to the implementation of S2104 in FIG2A, or the description of the embodiments in FIG2B to FIG2C.

[0468] This disclosure provides a processing method, including different triggering methods for supporting the coexistence of DO-A and DO-DTT services and for not supporting the coexistence of DO-A and DO-DTT services. When the coexistence of DO-A and DO-DTT services is supported, based on the DO-A indication in the paging, the device triggered by the DO-A service and the device triggered by the DO-DTT service participate in the access process together. When the coexistence of DO-A and DO-DTT services is not supported, the terminal of the DO-DTT service temporarily enters a waiting-for-re-access state or a service termination state.

[0469] Optionally, the device corresponds to the terminal in the foregoing embodiments.

[0470] To facilitate understanding of the embodiments of this disclosure, some embodiments are listed below:

[0471] Example 1: Supports the coexistence of DO-A and DO-DTT services.

[0472] Example 1.1:

[0473] When the reader receives the first signaling from a DO-A service terminal, it identifies a terminal that has triggered a DO-A service. The reader then terminates communication with any DT or DO-DTT service terminals, sends a repeat paging message for the currently ongoing DO-DTT service, and instructs the DO-A service terminal to access the service, ignoring the device ID information in the paging message.

[0474] Optionally, the reader corresponds to the network device 102 in the aforementioned embodiment, and the paging repeat message corresponds to the first information in FIG2B of the aforementioned embodiment.

[0475] Optionally, the paging message contains an indication message that instructs the terminal triggered by the DO-A service to begin accessing the network in the first slot.

[0476] In some embodiments, when a terminal triggering a DO-A service sends a 3-step CB access MSG1, the terminal triggering the DO-A service randomly selects an RN16 from the system-reserved RN16 range for access. Optionally, if no RN16 is reserved for a terminal triggering a DO-A service, the terminal triggering the DO-A service randomly generates an RN16.

[0477] Optionally, RN16 corresponds to the terminal identifier in the aforementioned embodiments.

[0478] In some embodiments, indication information is reported in the MSG3 of the 3-step CB access, which indicates the access cause of the DO-A service trigger and / or the amount of data reported by the DO-A service trigger.

[0479] Optionally, the data volume indication information can occupy 1 bit to indicate whether the amount of data to be transmitted exceeds the data volume threshold configured by the network or predefined by the system. Optionally, if the data volume threshold is configured by the network, it can be configured in the paging message mentioned above.

[0480] Optionally, the data volume indication information can occupy several bits, such as 3 bits, corresponding to 8 values, each of which corresponds to a predefined range of data volume values ​​in the system.

[0481] Example 1.2:

[0482] When the reader receives the first signaling from a DO-A service terminal and identifies a terminal that has triggered a DO-A service, the reader sends a special MSG2. This MSG2 contains DO-A service indication information and / or at least one AS-ID, but does not contain RN16 and / or MSG3 resources.

[0483] Optionally, MSG2 corresponds to the first information in Figure 2C of the aforementioned embodiment, and AS-ID corresponds to the access identifier in the aforementioned embodiment.

[0484] In some embodiments, after receiving the MSG2, the terminal triggered by the DO-A service selects an AS-ID and sends MSG3.

[0485] In some embodiments, when a terminal triggering a DO-A service sends a 3-step CB access MSG1, the terminal triggering the DO-A service randomly selects an RN16 from the system-reserved RN16 range for access. Optionally, if no RN16 is reserved for a terminal triggering a DO-A service, the terminal triggering the DO-A service randomly generates an RN16.

[0486] Optionally, RN16 corresponds to the terminal identifier in the aforementioned embodiments.

[0487] In some embodiments, indication information is reported in the MSG3 of the 3-step CB access, which indicates the access cause of the DO-A service trigger and / or the amount of data reported by the DO-A service trigger.

[0488] Optionally, the data volume indication information can occupy 1 bit to indicate whether the amount of data to be transmitted exceeds the data volume threshold configured by the network or predefined by the system. Optionally, if the data volume threshold is configured by the network, it can be configured in the paging message mentioned above.

[0489] Optionally, the data volume indication information can occupy several bits, such as 3 bits, corresponding to 8 values, each of which corresponds to a predefined range of data volume values ​​in the system.

[0490] In some embodiments, this embodiment is applicable when the reader receives the first instruction from the DO-A service terminal, before or during the response from the DO-DTT service terminal.

[0491] Example 1.3:

[0492] In some embodiments, the resources supporting DO-A and DO-DTT services are frequency-division multiplexed.

[0493] Optionally, the resources for DO-A services are reserved by the system.

[0494] In some embodiments, the resources supporting DO-A and DO-DTT services are time-division multiplexed.

[0495] Optionally, the resources for DO-A services are determined based on the receipt of a message or synchronization signal dedicated to DO-A services, such as radio resources after the time of receiving the message or synchronization signal being used for DO-A services.

[0496] Example 2: Supports the non-coexistence of DO-A and DO-DTT services.

[0497] In some embodiments, when the reader receives the first signaling from a DO-A service terminal and identifies a terminal that has triggered a DO-A service, the priority of the DO-A service is higher than that of the DO-DTT service.

[0498] In some embodiments, the reader sends a paging message for the DO-A service, for example, the paging message carries DO-A indication information.

[0499] Optionally, the paging message corresponds to the first information in Figure 2A of the aforementioned embodiment.

[0500] Optionally, the reader can send a notification to the terminal of the DO-DTT service to suspend or stop the service.

[0501] In some embodiments, paging messages are reused, and the messages carry at least one of the following:

[0502] Transaction ID: Used by the terminal to determine whether the paging message is sent repeatedly, and then to determine whether to respond to the paging message. Optionally, it can also identify an IoT service within a certain period of time. Optionally, the transaction ID corresponds to the third indication information in the aforementioned embodiment.

[0503] Paging ID: Used to indicate the terminal access network triggered by DO-A service, i.e. DO-A service indication information. Optionally, the paging ID corresponds to the first indication information in the aforementioned embodiments.

[0504] The service suspension instruction or service stop instruction may, optionally, correspond to the second instruction information in the foregoing embodiments.

[0505] In some embodiments, when a terminal receives a paging message from a DO-A service or a paging message indicating service termination, it performs one of the following actions:

[0506] The terminal considers the DO-DTT service to have stopped and clears all information related to the service, such as the Transaction ID.

[0507] The terminal perceives the DO-DTT service as suspended, and all terminals enter a state of waiting for reconnection to be triggered.

[0508] The embodiments disclosed above include different triggering methods that support the coexistence of DO-A and DO-DTT services and do not support the coexistence of DO-A and DO-DTT services. When the coexistence of DO-A and DO-DTT services is supported, based on the DO-A indication in the paging, the terminal triggered by the DO-A service and the terminal triggered by the DO-DTT service participate in the access process together. When the coexistence of DO-A and DO-DTT services is not supported, the terminal receiving the DO-DTT service temporarily enters a waiting-for-re-access state or a service termination state.
