The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0061] In the embodiments of the present application, the term "user equipment" (UE) or "terminal equipment" (TE) refers to, for example, a device that accesses a communication network through a network device and receives network services. A user equipment may be fixed or mobile and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, a tag, and so on.

[0064] For example, in scenarios such as the Ambient Internet of Things (also known as Ambient IoT, AIoT, or A-IoT), user devices or terminal devices can also be AIoT devices (also known as A-IoT devices).

[0067] Among the vast number of IoT devices, cellular mobile communication systems still lack the capacity to support a large number of lower-cost IoT terminals. To provide more robust, reliable, and complete IoT application solutions, supporting these lower-cost IoT terminals within 3GPP cellular mobile systems has become a pressing issue.

[0068] RFID systems are a solution for the massive and cost-effective deployment of IoT devices. They are widely used. Their advantages include low tag costs and affordability. RFID tags are small, limiting the size and material of the items they can be used on, making them suitable for various scenarios such as item management and tracking. Despite their low tag costs, the deployment and operating costs of RFID systems are higher than those of wide-area commercial networks. Deployment is typically localized, using dedicated networks, making it difficult to effectively distribute deployment costs. Regarding usage, if manual handheld tag readers are used, labor costs can become a major expense and are difficult to reduce. Using dedicated RFID ports or gateways to read and manage tags significantly increases deployment costs. Furthermore, RFID systems have a simple logical architecture and loose radio resource management, making it difficult to effectively manage interference from radio wave transmissions. Consequently, RFID systems generally have low system capacity and spectrum efficiency.

[0069] Compared to existing RFID systems, leveraging existing commercial mobile communication cellular networks (such as LTE and 5G NR systems) to support industry applications requiring tag-based IoT devices can significantly reduce deployment costs, thereby lowering the barrier to entry for deploying these IoT devices. Furthermore, existing commercial mobile communication cellular networks (such as LTE and 5G NR systems) offer significantly higher network security and wireless resource management effectiveness than existing RFID systems.

[0070] Taking 5G systems as an example, they provide reliable authentication, network coordination, and accurate and stable terminal device management mechanisms. These systems can safely and effectively reduce labor costs, thereby lowering the cost of using this type of IoT. They can also optimize the network to increase system capacity and spectrum efficiency. These reductions in deployment and operating costs will effectively promote the application of these IoT devices in business management and industrial manufacturing, accelerating the digitalization of these industries, improving production efficiency, and ultimately promoting social development.

[0071] As a new type of IoT terminal in the 5G system, Ambient IoT terminal devices (AIoT devices for short) are severely cost-constrained. The hardware capabilities of the devices are significantly weaker than those of ordinary smartphones and other IoT-type devices supported by existing cellular mobile communication systems. For example, Ambient IoT terminal devices may not have a stable power supply (for example, using ambient energy harvesting instead of conventional batteries), have a narrow bandwidth, and the internal crystal oscillator has limited accuracy and large errors due to cost constraints, as well as limited signal processing capabilities. In addition, the services that Ambient IoT terminal devices need to support are simpler than those of smartphones.

[0072] From the perspective of cost reduction, ambient IoT terminal devices do not need to support complex multi-layer management logic. During the discussion on the establishment of the 3GPP 5G NR Release 19 Ambient IoT research project, it was made clear that Ambient IoT devices do not support related functions such as RRC status, mobility, Hybrid Automatic Repeat reQuest (HARQ) and Automatic Repeat reQuest (ARQ).

[0073] Therefore, how network devices interact with AIoT devices to initiate AIoT-related services has become an urgent problem to be solved.

[0074] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0075] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application, and Figure 2 is another schematic diagram of a communication system according to an embodiment of the present application. Figures 1 and 2 schematically illustrate a situation using a terminal device and a network device as an example.

[0076] As shown in Figure 1, network devices can communicate directly with AIoT devices, directly sending signals to AIoT devices or directly receiving signals from AIoT devices; as shown in Figure 2, network devices can also go through intermediate nodes and use intermediate nodes to send signals to AIoT devices or use intermediate nodes to receive signals from AIoT devices.

[0077] The intermediate node can be a terminal device, a UE, or a network node, such as a relay, an IAB node, a repeater, etc., but the present application is not limited thereto. The intermediate node has the function of communicating with the network device in Figure 2, and also has at least the ability to send signals to and receive signals from the AIoT device. The sending of signals to and receiving of signals from the AIoT device mentioned here complies with the provisions and descriptions of the AIoT device in the communication standard protocol.

[0078] In the embodiments of the present application, a network device may send signals / information / configurations to an AIoT device, or an AIoT device may receive signals / information / configurations from a network device. This may be done directly by the network device and received by the AIoT device, or by the network device via an intermediate node and received by the AIoT device. This may also be done by the network device using other methods and received by the AIoT device, such as by the network device sending signals to the AIoT device with the help of an auxiliary node and received by the AIoT device. Unless otherwise specified, this application is not limited to this.

[0079] In the embodiments of the present application, when an AIoT device sends a signal / information to a network device, or when a network device receives a signal / information from an AIoT device, the AIoT device may send the signal and the network device may receive it directly, or the AIoT device may send the signal and the network device may receive it via an intermediate node, or the AIoT device may send the signal and the network device may receive it through other methods, such as the AIoT device sending the signal and the network device receiving it with the help of an auxiliary node. Unless otherwise specified, the present application is not limited to this.

[0080] The AIoT services currently defined for AIoT include device-originated-device-terminated triggered (DO-DTT) services and device-terminated (DT) services. Among them, the use scenarios of DO-DTT services are as follows: products on four-wheeled containers are transported throughout the logistics chain, such as flower auctions; A-IoT devices are assembled on containers. During the execution of the DO-DTT service, the A-IoT device is awakened and triggered by the network device on demand, and then the A-IoT device responds to the network device. The use scenarios of DT services are, for example: environmental electronic shelf labels, which help to automatically change price tags, inventory replenishment, dynamic price adjustments, customer behavior analysis, etc. During the execution of the DT service, the A-IoT device updates the label according to the request, and a fixed sending interval is not applied. The above usage scenarios are only examples of this application, and unless otherwise specified, this application is not limited to this.

[0081] As can be seen from the above service types, A-IoT-related services are currently all initiated by network devices. Therefore, network devices need to send paging-like messages to A-IoT devices. However, it is currently unclear how the network sends these paging-like messages to AIoT devices, nor how AIoT devices receive these paging-like messages.

[0082] In response to at least one of the above problems, embodiments of the present application provide a data processing method, a data sending method, a device, and a communication system.

[0083] Embodiments of the first aspect

[0084] The present application embodiment provides a data processing method, which is described from the perspective of a terminal device (AIoT device). FIG3 is a schematic diagram of the data processing method of the present application embodiment. As shown in FIG3 , the method includes:

[0085] 301, receiving a first message related to an Ambient Internet of Things (AIoT) service;

[0086] 302. Perform AIoT service-related processing according to the first message.

[0087] According to the above embodiment, the terminal device receives a first message related to an Ambient Internet of Things (AIoT) service and performs processing related to the AIoT service based on the first message. This helps the network device request the terminal device to initiate a service or send data to the terminal device, allowing the AIoT service to continue, thereby realizing functions related to the AIoT.

[0088] It is worth noting that FIG3 above merely illustrates an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be removed. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description in FIG3 above.

[0089] In some embodiments, in 301, the first message is a paging message; or the first message is a paging-like message, i.e., a message similar to a paging message. The first message may also be referred to as an initial message or other similar names.

[0090] In some embodiments, the network device sends the first message to all AIoT devices in a cell or a tracking area (TA), for example, by unicast, multicast, or broadcast, but not all AIoT devices need to respond to the first message, that is, not all AIoT devices need to perform AIoT service-related processing according to the first message; or, the network device sends the first message to a group or a specific AIoT device in a cell or a tracking area, for example, by multicast or unicast. Therefore, the first message is used to indicate one or more AIoT devices, and the AIoT devices indicated by the first message are the AIoT devices that the network device hopes to initiate AIoT-related services.

[0091] In some embodiments, the first message includes or indicates at least one of the following information:

[0092] The identification of the AIoT device, the identification of the group to which the AIoT device belongs, the capabilities of the AIoT device, the location information of the AIoT device, the reason for paging the AIoT device, the attributes or type of the AIoT device, and the type or identification of the business that the AIoT device will perform.

[0093] The above information can indicate one or more AIoT devices. The meaning of each information is as follows:

[0094] Identification of AIoT device: Identification information that can identify an AIoT device, for example, it can be an assigned temporary ID, or a device ID pre-configured or written into the register of the AIoT device, or an identifier generated based on an algorithm, etc. Based on the identifier, an AIoT device can be determined. The first message may include the identifiers of one or more AIoT devices. The AIoT device with the identifier of the AIoT device will receive and process the first message, and may respond (for example, for DO-DTT services).

[0095] Identification of the group to which the AIoT device belongs: AIoT devices are divided into at least one group, each AIoT device group includes at least one AIoT device, and each AIoT device group has an identification that can determine the AIoT device group, that is, the identification of the group to which the AIoT device belongs, which can be, for example, an assigned group temporary identification (temporary ID), or a device group identification (device group ID) pre-configured or written into the register of the AIoT device, or a group identification generated based on an algorithm, etc. According to the identification of the group to which the AIoT device belongs, an AIoT device group can be determined, and all AIoT devices in the AIoT device group receive and process the first message, and may respond. The first message may include the identification of the group to which one or more AIoT devices belong.

[0096] AIoT device capabilities: When the first message includes the capabilities of an AIoT device, an AIoT device with these capabilities receives and processes the first message and may respond. Examples of AIoT device capabilities include independent signal generation or amplification capabilities, radio frequency (RF) components, RF capabilities, and energy storage.

[0097] AIoT device location information: When the first message includes the location information of an AIoT device, the AIoT device whose location matches the location information receives and processes the first message and may respond. The location information of the AIoT device may include, for example, at least one of GPS geographic location information, region identifier, tracking area identifier, cell identifier, and indoor or outdoor location.

[0098] The reason for paging the AIoT device is used to indicate the reason for paging the AIoT device. The reason may include, for example, at least one of the following: inventory request, command, select, query, positioning, and sensor. For another example, the reason may be at least one of the following: indoor inventory, indoor sensors, indoor positioning, indoor command, outdoor inventory, outdoor sensors, outdoor positioning, and outdoor command. When the first message includes the reason for paging the AIoT device, the AIoT device performs relevant operations according to the reason and may reply with a corresponding response message.

[0099] The attribute or type of the AIoT device is used to indicate the attribute or type of the AIoT device being paged, and may include, for example, at least one of the following: a field stored in an AIoT device register, device type A (device that transmits backscatter), device type B (device that transmits backscatter and uses an amplified feedback signal), or device type C (device with an activated radio frequency component). When the first message includes the attribute or type of the AIoT device, the AIoT device with the attribute or type receives and processes the first message and may respond.

[0100] The type or identifier of the service to be performed by the AIoT device indicates what type of service or session the paged AIoT device will perform, and may include, for example, at least one of the following: DO-DTT service, DT service, DO service, session ID, etc. When the first message includes the type or identifier of the service to be performed by the AIoT device, the AIoT device that will perform the service consistent with the type or identifier receives and processes the first message, and may respond.

[0101] In some embodiments, the first message is also used to indicate information modification in the AIoT system. For example, the first message may include the modified value of a parameter in the AIoT system (e.g., information of a tag in the AIoT system), or indicate a changed parameter in the AIoT system, or indicate that information modification has occurred in the AIoT system.

[0102] In some embodiments, the first message may be the first message of an inventory or command or sensor or positioning or query or selection process, such as a request message of the above process, or the first message may include the first message of the above process.

[0103] In some embodiments, the first message may not be encrypted and / or integrity protected, that is, it can be received and correctly decoded by all AIoT devices, or the first message may be encrypted and / or integrity protected, for example, the network device may use a public key and / or public security algorithm to encrypt and / or integrity protect the first message so that all AIoT can receive and correctly decode the first message, or the network device may use a key and / or security algorithm of an AIoT device or a group of AIoT devices to encrypt and / or integrity protect the first message so that only the AIoT device or the group of AIoT devices can receive and correctly decode the first message. In this embodiment, encryption and / or integrity protection can be performed at the access layer (e.g., RRC or L2) or the non-access layer (NAS).

[0104] The following embodiment illustrates the generation and sending of the first message.

[0105] In some embodiments, the first message is generated by a radio access network (RAN). For example, in the communication systems shown in Figures 1 and 2, network equipment includes a radio access network and a core network (CN). The radio access network includes, for example, a base station (BS) or gNB. The control layer (similar to the RRC layer) or Layer 2 (L2, similar to the MAC layer and / or RLC layer and / or PDCP layer) of the radio access network generates the first message.

[0106] In some embodiments, the radio access network generates the first message based on the first request of the core network. For example, the core network generates the first request and sends the first request to the radio access network. The radio access network generates the first message after receiving the first request. The first request can be sent via an NG Application Protocol (NGAP) message. For example, the first request can be an indication in an NGAP message, or the first message (e.g., a request message or a query message) of a process such as inventory, command, sensors, or positioning, and is included in a container of the NGAP message.

[0107] In some embodiments, the first request includes information related to the first message, and the information related to the first message is used to generate the first message.

[0108] In some embodiments, the information related to the first message includes the identification of the second AIoT device, the identification of the group to which the second AIoT device belongs, the capabilities of the second A-IoT device, the location information of the second A-IoT device, the second reason for paging the AIoT device, the attributes or type of the second AIoT device, the type or identification of the business to be performed by the second AIoT device, and the like. The wireless access network generates a first message based on information related to the first message, wherein the identifier of the AIoT device included in the first message may be the same as or different from the identifier of the second AIoT device, and / or, the identifier of the group to which the AIoT device included in the first message belongs may be the same as or different from the identifier of the group to which the second AIoT device belongs, and / or, the capabilities of the A-IoT device included in the first message may be the same as or different from the capabilities of the second A-IoT device, and / or, the location information of the A-IoT device included in the first message may be the same as or different from the location information of the second A-IoT device, and / or, the reason for paging the AIoT device included in the first message may be the same as or different from the second reason for paging the AIoT device, and / or, the attributes or type of the AIoT device included in the first message may be the same as or different from the attributes or type of the second AIoT device, and / or, the type or identifier of the service to be performed by the AIoT device included in the first message may be the same as or different from the type or identifier of the service to be performed by the second AIoT device.

[0109] For example, in the case where the information related to the first message includes the identifier of the second AIoT device, the wireless access network (for example, through the NGAP layer) parses the information related to the first message to obtain the identifier of the second AIoT device, and generates a first message based on the parsed identifier of the second AIoT device. The identifier of the AIoT device indicated by the first message may be the same as the identifier of the second AIoT device, or the identifier of the AIoT device indicated by the first message may have a corresponding relationship with the identifier of the second AIoT device, that is, the identifier of the AIoT device may be different from the identifier of the second AIoT device. For the case where the information related to the first message includes other content, it is similar to this and will not be repeated. In some embodiments, the first request includes the period or time offset for the wireless access network to send the first message. For example, the wireless access network sends the first message to the terminal device according to the period or time offset for sending the first message in the first request.

[0110] In some embodiments, the first request includes information about an intermediate node associated with the terminal device. For example, the wireless access network determines one or more intermediate nodes based on the information about the intermediate nodes associated with the terminal device in the first request, and sends the first message to the terminal device through the determined one or more intermediate nodes. The information about the intermediate nodes associated with the terminal device is sent to the wireless access network by the core network through the first request.

[0111] In some embodiments, the wireless access network sends the generated first message to the terminal device.

[0112] In some embodiments, the radio access network periodically transmits the first message. For example, after generating the first message, the radio access network periodically transmits the first message to the terminal device. The period or time offset for transmitting the first message by the radio access network may be predefined or configured by the core network. For example, the core network may configure the period and / or time offset for transmitting the first message to the radio access network via an NGAP message. In this embodiment, after generating the first message, the radio access network periodically transmits the first message without any instruction or request from the core network.

[0113] In some embodiments, the radio access network sends the first message based on the first request from the core network. For example, after receiving the first request from the core network, the radio access network generates the first message and sends it once to the terminal device. When the radio access network receives the first request from the core network again, it regenerates the first message and sends it once to the terminal device. In this embodiment, the radio access network sends the first message once each time it receives the first request from the core network.

[0114] In some embodiments, the radio access network periodically sends the first message based on a first request from the core network. For example, if the first request includes a period and / or time offset for the radio access network to send the first message, the radio access network generates the first message based on the first request and sends the first message to the terminal device based on the period and / or time offset for sending the first message in the first request. In this embodiment, upon receiving a first request from the core network, the radio access network periodically sends the first message.

[0115] In some embodiments, receiving the first message includes: the terminal device receiving the first message from the wireless access network. For example, FIG4 is an interactive signaling diagram of the communication system shown in FIG1. ​​As shown in FIG4, the interaction between the terminal device, the wireless access network, and the core network is as follows:

[0116] 401. The core network sends a first request to the wireless access network. The first request is sent, for example, via an NGAP message. For details related to the first request, please refer to the aforementioned embodiment and will not be repeated here.

[0118] 403. The wireless access network sends a first message to the terminal device. The first message is sent, for example, via an RRC message or a MAC message (or other layer 2 message).

[0119] Thus, the terminal device performs processing related to the AIoT service according to the first message, such as initiating random access, and may also perform subsequent signaling and / or data transmission and / or reception.

[0120] In some embodiments, receiving the first message includes: the terminal device receiving the first message generated by the wireless access network via the intermediate node. For example, FIG5 is an interactive signaling diagram of the communication system shown in FIG2. As shown in FIG5, the interaction between the terminal device, the intermediate node, the wireless access network, and the core network is as follows:

[0121] 501. The core network sends a first request to the wireless access network. The first request is sent, for example, via an NGAP message. The first request includes information related to the first message. For content related to the first request, please refer to the aforementioned embodiment and will not be repeated here.

For details on generating the first message, see the previous embodiment and will not be repeated here.

[0123] 503. The wireless access network sends the generated first message to the terminal device via the intermediate node. For example, the wireless access network sends the first message to the intermediate node through an RRC message or a MAC message (or other layer 2 message). The intermediate node forwards the first message to the terminal device. For example, after the intermediate node receives the first message at the RRC layer or the MAC layer (or other layer 2 message) in the Uu interface, the intermediate node sends the first message to the terminal device through the RRC message or the MAC message (or other layer 2 message) in the interface between the intermediate node and the terminal device.

[0124] In some embodiments, in 501, the first request sent by the core network also includes a period or time offset for the intermediate node to send the first message. Accordingly, in 502, the radio access network forwards the first message in the first request and the period or time offset for the intermediate node to send the first message to the intermediate node; in 503, the intermediate node sends the first message to the terminal device based on the received "period or time offset for the intermediate node to send the first message."

[0125] In some embodiments, in 501, the first request sent by the core network also includes information about an intermediate node associated with the terminal device. Accordingly, in 502, the radio access network determines the intermediate node associated with the terminal device based on the "information about the intermediate node associated with the terminal device" and sends the generated first message to the determined intermediate node via an RRC message or a MAC message (or other layer 2 message).

[0126] In some embodiments, in 503 , the intermediate node only forwards the first message without processing the first message.

[0127] In some embodiments, the first message is generated by an intermediate node, such as an intermediate node in the communication system shown in FIG2 . For example, the first message is generated by a control layer or layer 2 of the intermediate node, such as an RRC layer or a NAS layer.

[0128] In some embodiments, the intermediate node generates the first message according to a first request from the core network; the first request includes information related to the first message, and / or a period and / or time offset for the intermediate node to send the first message.

[0129] In some embodiments, the first request is sent via a Non-Access Stratum (NAS) message.

[0130] FIG6 is another interactive signaling diagram of the communication system shown in FIG2 . As shown in FIG6 , the interactions among the terminal device, the intermediate node, the radio access network, and the core network are as follows:

[0131] 601. The core network sends a first request to the intermediate node through the wireless access network. The first request is, for example, a NAS message, which is included in an NGAP message. For example, it can be an indication in the NGAP message, or the first message of a process such as an inventory, command, sensor, or positioning (such as a request message or query message), which is included in a container of the NGAP message.

[0132] The core network first sends the NAS message corresponding to the first request to the wireless access network through an NGAP message. The wireless access network forwards the NAS message containing the first request to the intermediate node. The first request includes information related to the first message and / or the period or time offset for sending the first message by the intermediate node. For the content related to the first request, please refer to the previous embodiment and will not be repeated here.

[0133] 602: The intermediate node generates a first message based on the first request. For example, the intermediate node parses the NAS message corresponding to the first request forwarded by the RAN to obtain the first request, and generates the first message based on the first request.

[0136] In some embodiments, in 601 , the radio access network only forwards the NAS message in the NGAP message without processing it.

[0137] In some embodiments, in 601, the NGAP message sent by the core network to the wireless access network also includes information of the intermediate node associated with the terminal device. Thus, the wireless access network determines the intermediate node associated with the terminal device based on the "information of the intermediate node associated with the terminal device" and forwards the NAS message in the NGAP message to the determined intermediate node through an RRC message or a MAC message.

[0138] In some embodiments, in 601, the NGAP message sent by the core network to the radio access network also includes the period and / or time offset at which the intermediate node sends the first message. The radio access network forwards the "period and / or time offset at which the intermediate node sends the first message" to the intermediate node via an RRC message or a MAC message. Accordingly, in 603, the intermediate node sends the generated "first message" to the terminal device according to the "period and / or time offset at which the intermediate node sends the first message."

[0139] In some embodiments, the intermediate node generates the first message according to a second request of the radio access network, where the second request includes information related to the first message and / or a period and / or time offset for the intermediate node to send the first message.

[0140] In some embodiments, the second request is sent via a Radio Resource Control (RRC) message or a layer 2 message of a Uu interface.

The first request includes information related to the first message, and / or a period and / or time offset for the intermediate node to send the first message, and / or information about the intermediate node associated with the terminal device. The first request is sent, for example, via an NGAP message.

[0145] 702. After receiving the first request, the wireless access network generates a second request based on the first request. For example, the wireless access network parses the first request, generates the second request based on the "information related to the first message" and / or the "period and / or time offset at which the intermediate node sends the first message" in the first request, and determines the intermediate node associated with the terminal device based on the "information of the intermediate node associated with the terminal device" in the first request.

[0146] 703. The radio access network sends the generated second request to the determined intermediate node. For example, the radio access network sends the second request via a Radio Resource Control (RRC) message or a layer 2 message of a Uu interface.

[0147] 704. The intermediate node generates a first message based on the second request. For example, the intermediate node parses the second request and generates the first message based on the "information related to the first message" in the second request. For example, the first message may be generated by a control layer (e.g., such as an RRC layer) or layer 2 (e.g., such as a MAC layer) of the intermediate node.

[0148] 705: The intermediate node sends the first message to the terminal device. For example, the intermediate node sends the first message via a Radio Resource Control (RRC) message or a layer 2 message of an interface with the terminal device.

[0149] In some embodiments, the intermediate node sends the generated first message to the terminal device in the following manner:

[0150] The intermediate node periodically sends the first message; wherein the period and / or time offset of the intermediate node sending the first message is configured by the core network or RAN, or predefined; or

[0151] The intermediate node sends the first message based on the first request of the CN or the second request of the RAN; for example, the intermediate node sends the first message to the terminal device once when receiving the first request or the second request; or

[0152] The intermediate node periodically sends the first message based on the first request of the CN or the second request of the RAN; for example, after receiving the first request or the second request once, the intermediate node periodically sends the first message to the terminal device, wherein the period or time offset for the intermediate node to send the first message is configured by the core network, for example, through the first request or the second request.

[0153] In some embodiments, when the first message is generated by the intermediate node, the terminal device receives the first message from the intermediate node.

[0154] In some embodiments, the first message is generated by a core network (CN). For example, the first message is generated by a NAS layer of the core network. For details about the first message, see the previous embodiment and will not be repeated here.

[0155] In some embodiments, the terminal device receives the first message generated by the core network from the wireless access network, that is, the core network sends the first message to the terminal device through the wireless access network.

[0156] FIG8 is another interactive signaling diagram of the communication system shown in FIG1 . As shown in FIG8 , the interactions among the terminal device, the wireless access network, and the core network are as follows:

[0157] 801, the core network sends the generated first message to the radio access network; for example, the first message is included in a container of an NGAP message, and the core network sends the first message via an NGAP message;

[0158] 802. After receiving the NGAP message, the wireless access network forwards the first message in the NGAP message to the terminal device; for example, the wireless access network sends the first message in the NGAP message to the terminal device through an RRC message or a MAC message, for example, putting the first message in a container of the RRC message or the MAC message and sending it to the terminal device.

[0159] In some embodiments, in 801, the NGAP message further includes a period and / or time offset for the wireless access network to send the first message. Accordingly, in 802, the wireless access network sends the first message to the terminal device according to the "period and / or time offset for sending the first message" in the NGAP message.

[0160] FIG9 is another interactive signaling diagram of the communication system shown in FIG1 . As shown in FIG9 , the interactions among the terminal device, the wireless access network, and the core network are as follows:

[0161] 901. The core network sends the generated first message to the terminal device through the wireless access network, wherein the first message is, for example, a NAS message, which is included in the NGAP message. For example, it can be an indication in the NGAP message, or the first message of a process such as inventory, command, sensors, or positioning (such as a request message or a query message, etc.), which is included in the container of the NGAP message.

[0162] The core network first sends the NAS message corresponding to the first message to the radio access network via an NGAP message. The radio access network forwards the NAS message corresponding to the first request to the terminal device, for example, by sending the NAS message via an RRC message or a MAC message. The content related to the first message is described in the previous embodiment and is not repeated here.

[0163] In some embodiments, in 901, the NGAP message also includes the period and / or time offset for the wireless access network to send the first message. Accordingly, the wireless access network forwards the first message to the terminal device according to the "period and / or time offset for sending the first message".

[0164] In some embodiments, the terminal device parses the first message at the control layer or L2 layer. For example, in the interactive signaling diagram shown in FIG8 , the first message received by the terminal device is included in an RRC message or a MAC message, and therefore, the terminal device parses the first message at the RRC layer or the MAC layer. For another example, in the interactive signaling diagram shown in FIG9 , the first message received by the terminal device is a NAS message, and therefore, the terminal device parses the first message at the NAS layer.

[0165] In some embodiments, the terminal device receives the first message generated by the core network from the intermediate node, that is, the core network sends the first message to the terminal device through the wireless access network and the intermediate node.

[0166] FIG10 is another interactive signaling diagram of the communication system shown in FIG2 . As shown in FIG10 , the interactions among the terminal device, the wireless access network, the intermediate node, and the core network are as follows:

[0167] 1001. The core network sends a generated first message to the radio access network. For example, the core network sends the first message via an NGAP message, and the container of the NGAP message includes the first message. For details related to the first message, refer to the previous embodiment and are not repeated here.

[0168] 1002. The wireless access network forwards the first message in the NGAP message to the intermediate node. For example, the wireless access network sends the first message in the NGAP message to the intermediate node through an RRC message or a media access control (MAC) message. The first message is included in the container of the RRC message or the MAC message (or other layer 2 message).

[0169] 1003. The intermediate node sends a first message in an RRC message or a MAC message sent by the radio access network to the terminal device. For example, the intermediate node sends the first message via a NAS message, an RRC message, or a MAC message in an interface between the intermediate node and the terminal device. The first message is included in the NAS message or in a container of the RRC message or the MAC message (or other layer 2 message).

[0170] In some embodiments, in 1001, the NAGP message sent by the core network to the wireless access network also includes information of the intermediate node associated with the terminal device. The wireless access network determines the intermediate node associated with the terminal device based on the "information of the intermediate node associated with the terminal device" and sends the first message to the determined intermediate node through an RRC message or a MAC message.

[0171] In some embodiments, in 1001, the NAGP message sent by the core network to the radio access network also includes the period and / or time offset at which the intermediate node sends the first message. The radio access network sends the first message and / or the "period and / or time offset at which the intermediate node sends the first message" to the intermediate node via an RRC message or a MAC message. Accordingly, in 1002, the intermediate node sends the first message to the terminal device based on the "period and / or time offset at which the intermediate node sends the first message."

[0172] In some embodiments, the core network sends a first message to the intermediate node via a NAS message, and the radio access network only forwards the NAS message corresponding to the first message. In the intermediate node, the first message received from the RAN is passed to the NAS layer, i.e., the intermediate node parses the first message. Figure 11 is another interactive signaling diagram of the communication system shown in Figure 2. As shown in Figure 11, the interactions between the terminal device, the radio access network, the intermediate node, and the core network are as follows:

[0173] 1101. The core network sends a generated first message to the intermediate node through the wireless access network, wherein the first message, for example, is a NAS message, which is included in the NGAP message. For example, it can be an indication in the NGAP message, or the first message of a process such as inventory, command, sensors, or positioning (such as a request message or query message, etc.), which is included in the container of the NGAP message.

[0174] The core network first sends the NAS message corresponding to the first message to the radio access network via an NGAP message. The radio access network forwards the NAS message corresponding to the first request to the intermediate node, for example, by sending the NAS message via an RRC message or a MAC message. The details related to the first message are described in the previous embodiment and are not repeated here.

[0175] 1102 : The intermediate node transmits the NAS message corresponding to the first message received from the radio access network to the NAS layer of the intermediate node for parsing.

[0176] 1103. The intermediate node sends the parsed first message to the terminal device via a NAS message, an RRC message, or a MAC message (or other layer 2 message).

[0177] In Figure 11, the core network directly sends the first message to the intermediate node through a NAS message, that is, the core network sends the NAS message corresponding to the first message to the intermediate node, and the wireless access network only forwards the NAS message corresponding to the first message without parsing it; the intermediate node parses the NAS message corresponding to the first message to obtain the first message, and then sends the first message to the terminal device through a NAS message or an RRC message or a MAC message (or other layer 2 message).

[0178] In some embodiments, in 1101, the NAGP message sent by the core network to the wireless access network also includes information of the intermediate node associated with the terminal device. The wireless access network determines the intermediate node associated with the terminal device based on the "information of the intermediate node associated with the terminal device" and sends the NAS message corresponding to the first message in the NAGP message to the determined intermediate node through an RRC message or a MAC message.

[0179] In some embodiments, in 1101, the NAGP message sent by the core network to the wireless access network also includes the period and / or time offset for the intermediate node to send the first message. The wireless access network sends the received "NAS message corresponding to the first message" and / or the "period and / or time offset for the intermediate node to send the first message" to the intermediate node via an RRC message or a MAC message. Correspondingly, in 1103, the intermediate node sends the first message to the terminal device based on the "period and / or time offset for the intermediate node to send the first message."

[0180] In some implementations, in 1101, the NAS message included in the NAGP message sent by the core network to the wireless access network also includes the period and / or time offset for the intermediate node to send the first message. That is, the core network sends the first message and / or the period and / or time offset for the intermediate node to send the first message to the intermediate node through the NAS message. The wireless access network forwards the "first message" and "the period and / or time offset for the intermediate node to send the first message" in the NAS message to the intermediate node. Accordingly, in 1102, the intermediate node parses the NAS message to obtain the first message and the period and / or time offset for the intermediate node to send the first message; in 1103, the intermediate node sends the first message to the terminal device according to the period and / or time offset for the intermediate node to send the first message.

[0181] In some embodiments, the core network sends a first message to the terminal device via a NAS message, and the radio access network and intermediate nodes only forward the NAS message corresponding to the first message. In the intermediate node, the first message received from the RAN is not passed to the NAS layer, that is, the intermediate node does not parse the first message. Figure 12 is another interactive signaling diagram of the communication system shown in Figure 2. As shown in Figure 12, the interaction between the terminal device, the radio access network, the intermediate node, and the core network is as follows:

[0182] 1201. The core network sends the generated first message to the terminal device through the wireless access network and the intermediate node, wherein the first message is, for example, a NAS message, which is included in the NGAP message. For example, it can be an indication in the NGAP message, or the first message of a process such as inventory, command, sensors, or positioning (such as a request message or a query message, etc.), which is included in the container of the NGAP message.

[0183] The core network first sends a NAS message corresponding to the first message to the radio access network via an NGAP message. The radio access network then forwards the NAS message corresponding to the first request to an intermediate node, for example, via an RRC message or a MAC message. The details related to the first message are described in the previous embodiment and are not repeated here.

[0184] The intermediate node sends the NAS message corresponding to the first message received from the radio access network to the terminal device. For example, the intermediate node sends the NAS message corresponding to the first message via an RRC message or a MAC message in the interface between the intermediate node and the terminal device.

[0185] In Figure 12, the core network directly sends the first message to the terminal device through the NAS message, that is, the core network sends the NAS message corresponding to the first message to the terminal device, and the wireless access network and the intermediate node only forward the NAS message corresponding to the first message without parsing it.

[0186] In some embodiments, in 1201, the NAGP message sent by the core network to the wireless access network also includes information of the intermediate node associated with the terminal device. The wireless access network determines the intermediate node associated with the terminal device based on the "information of the intermediate node associated with the terminal device" and sends the NAS message corresponding to the first message in the NAGP message to the determined intermediate node through an RRC message or a MAC message (or other layer 2 message).

[0187] In some embodiments, in 1201, the NAGP message sent by the core network to the radio access network also includes the period and / or time offset for the intermediate node to send the first message. The radio access network sends the received "NAS message corresponding to the first message" and / or the "period and / or time offset for the intermediate node to send the first message" to the intermediate node via an RRC message or a MAC message. Accordingly, the intermediate node sends the "NAS message corresponding to the first message" to the terminal device based on the "period and / or time offset for the intermediate node to send the first message."

[0188] In some embodiments, the terminal device parses the first message at the control layer or L2 layer. For example, in the interactive signaling diagrams shown in Figures 10 and 11, the first message received by the terminal device is included in an RRC message or a MAC message, so the terminal device parses the first message at the RRC layer or the MAC layer. For another example, in the interactive signaling diagram shown in Figure 12, the first message received by the terminal device is included in a NAS message, so the terminal device parses the first message at the NAS layer.

[0189] In some embodiments, the terminal device receives the first message using a physical control channel and / or a physical traffic channel; and the first message has a specific format or identifier at the physical layer, and the format or identifier is used by the physical layer to identify the first message. Thus, the physical layer of the terminal device receives the message via the physical control channel and / or the physical traffic channel, and identifies whether the message is the first message based on the format or identifier of the message.

[0190] In some embodiments, the method further comprises:

[0191] The MAC layer or layer 2 of the terminal device parses the first message; for example, the first message has a specific MAC CE format or a specific L2 PDU format.

[0192] And the physical layer of the terminal device uses a control channel and / or a traffic channel to transmit the first message to the MAC layer or layer 2 of the terminal device.

[0193] In some embodiments, the method further comprises:

[0194] The RRC layer or NAS layer of the terminal device parses the first message; for example, the first message has a specific RRC structure or NAS message structure, etc.

[0195] The physical layer of the terminal device uses a traffic channel to transmit the first message to the MAC layer or layer 2 of the terminal device, and the MAC layer or layer 2 of the terminal device uses a control channel and / or a traffic channel to transmit the first message to the RRC layer or NAS layer of the terminal device.

[0196] In some embodiments, the method further comprises:

[0197] When at least one of the following signals is detected, the terminal device starts detecting or receiving the first message:

[0198] Carrier Wave (CW), which comes from other nodes within the topology and / or outside the topology;

[0199] Specific physical layer reference signals or synchronization signals, such as reader-to-device physical layer reference signals or synchronization signals;

[0200] Specific physical layer control signals, such as reader-to-device physical control signals;

[0201] A specific physical layer channel, such as a physical layer control channel or a physical layer traffic channel (e.g., a reader-to-device physical channel).

[0202] In some embodiments, the terminal device starts detecting or receiving the first message when the received power of the CW is higher than a specific threshold, or when the received power of the CW is higher than a specific threshold for a period of time T.

[0203] Therefore, when the terminal device detects at least one of the above signals, it starts to detect or receive the first message, which enables the terminal device to have a certain amount of energy storage to receive the first message or reduce the energy consumption of the terminal device.
