The base station is not limited to any specific technical terminology. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for introduction, and the specific type of base station is not limited.

[0024] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).
[0025] The AIoT device 14 features ultra-low complexity and ultra-low power consumption. It is a device used to implement IoT services. The AIoT device 14 can be powered through energy harvesting; it may not have a battery or may have limited energy storage capacity (e.g., using a capacitor). This type of device has low overall power consumption, including low-power signal reception and low-power signal transmission. Due to its low overall power consumption, the energy for communication can be derived from the environment, such as wind power, kinetic energy, heat energy, or radio frequency (RF) signals. It can also be referred to as an Ambient IoT or Passive IoT device, or a response device.
[0026] In related technologies, environmental IoT devices can be characterized based on their energy storage capacity and ability to generate and transmit radio frequency signals. AIoT devices 14 can be of the following types: 1) Device A: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission.
[0027] 2) Device B: It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of the reflected signal.
[0028] 3) Device C: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.
[0029] In related technologies, tags in Radio Frequency Identification (RFID) systems are also considered AIoT devices14. A reader identifies the IDs and reads data from backscatter communication (BSC) devices (i.e., tags) within the coverage area. Since RFID was initially used for automated inventory management of large quantities of goods, the process of identifying tags and reading data is also known as inventory management.
[0030] Figure 2a A schematic diagram of the inventory process for a tag is shown, such as... Figure 2aAs shown, after the reader sends a query command, the tag responds with a reply. For example, the tag generates a 16-bit random number and sends it to the reader. Then, the reader sends the sequence to the tag via an acknowledgment (ACK) command. After the tag successfully verifies the sequence in the ACK, it sends the relevant data to the reader.
[0031] Figure 2b The commonly used control commands in RFID are shown in Table 1.
[0032] Table 1.
[0033] Figure 3a It shows in Figure 1a The business process diagram for AIoT inventory under the topology connection shown is as follows: Figure 3a As shown, this business process mainly includes the following steps: Step 1: The AIoT core network sends an inventory request to the AIoT RAN nodes; Step 2: The AIoT RAN node sends an inventory response to the AIoT core network; Step 3: The AIoT RAN node and AIoT devices perform the inventory process through the AIoT interface; Step 4a: The AIoT RAN node sends an inventory report to the AIoT core network; Step 4b, optionally, if there are multiple AIoT devices, the AIoT RAN node continues to send inventory reports of other AIoT devices to the AIoT core network.
[0034] Figure 3b It shows in Figure 1b The business process diagram for AIoT inventory under the topology connection shown is as follows: Figure 3b As shown, this business process mainly includes the following steps: Step 1: The AIoT core network sends an inventory request to the AIoT-enabled gNB; Step 2: The AIoT-enabled gNB sends an inventory response to the AIoT core network; Step 3: The AIoT-enabled gNB, AIoT-enabled UE, and AIoT device perform the inventory process through the AIoT interface and the air interface (Uu). Step 4a: The AIoT RAN node sends an inventory report to the AIoT core network; Step 4b, optionally, if there are multiple AIoT devices, the AIoT RAN node continues to send inventory reports of other AIoT devices to the AIoT core network.
[0035] However, in related technologies, base stations communicating with the core network may be unable to communicate with AIoT devices or AIoT readers for various reasons. For example, in dual connectivity (DC) deployment scenarios, such as the 4G and 5G dual connectivity (EUTRA-NR Dual Connectivity, EN-DC) scenario, the EN-DC master node (MN) only supports the Long Term Evolution (LTE) air interface, and the MN cannot directly execute AIoT tasks / services with AIoT devices (LTE Uu does not support AIoT technology). Another example is when RAN node 1 receives an AIoT task / service request initiated by the CN node; if BS1 resources are insufficient or the AIoT device is not within BS1 coverage, BS1 cannot execute the AIoT task / service with the AIoT device. This may result in the application server's service requests sent to the AIoT device through the core network failing to reach the AIoT device or AIoT reader, thus preventing the execution of AIoT services.
[0036] To address the aforementioned issues, this application provides a service request method, network-side device, and storage medium. In the technical solution provided in this application, a CN node (e.g., an AIoT function node, AMF node) initiates an AIoT service request to RAN node 1 (e.g., a dual-connection master node MN). RAN node 1 selects RAN node 2 (e.g., a dual-connection auxiliary node SN, or a RAN node adjacent to RAN node 1) and forwards the AIoT service request to RAN node 2. RAN node 2 then selects an AIoT reader / AIoT device (AIoT terminal / device) to execute the AIoT service. Alternatively, the CN node (e.g., an AIoT function node, AMF node) forwards the AIoT service request to RAN node 2 (e.g., a dual-connection auxiliary node SN) through RAN node 1 (e.g., a dual-connection master node MN). RAN node 2 then selects an AIoT reader / AIoT device (AIoT terminal / device) to execute the AIoT service.
[0037] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0038] Figure 4 This diagram illustrates a service request method according to an embodiment of this application. This method 400 can be executed by a first RAN node. In other words, the method can be executed by software or hardware installed on the first RAN node. Figure 4 As shown, the method may include the following steps.
[0039] S410, the first RAN node receives an AIoT service request sent by the core network node, wherein the AIoT service request carries information about an AIoT reader or AIoT device.
[0040] In this embodiment of the application, the core network node (e.g., AIoT function or AMF) can send an AIoT service request carrying information about the AIoT reader or AIoT device to the first RAN node when the AIoT reader or AIoT device needs to perform AIoT services. For example, the AIoT service request may carry the identification information of the AIoT reader or AIoT device, or the location information of the AIoT reader or AIoT device.
[0041] S412, the first RAN node forwards the AIoT service request to the second RAN node, wherein the second RAN node is used to page the AIoT reader or AIoT device performing the AIoT service.
[0042] Optionally, in this embodiment of the application, the AIoT service request may carry AIoT service resource request information, which may include at least one of the following: 1) First information, the first information is used to instruct the configuration of AIoT service resources for the AIoT reader or AIoT device through the Signalalling RadioBearer (SRB) 3; 2) Second information, which is used to instruct the configuration of AIoT service resources for the AIoT reader or AIoT device by splitting SRB 1; 3) Third information, which is used to instruct the AIoT reader or AIoT device to configure AIoT service resources through a dedicated SRB. In other words, the third information instructs the configuration of AIoT service resources through a newly added SRB.
[0043] In this embodiment, after receiving an AIoT service request, the first RAN node can forward the AIoT service request to the second RAN node, which then pages the AIoT reader or AIoT device executing the AIoT service. This allows the first RAN node to send the AIoT service request to the second RAN node, which then selects the AIoT reader or AIoT device to execute the AIoT service. This solves the problem that service requests sent from the core network to the AIoT device cannot reach the AIoT device or AIoT reader, ensuring the successful execution of the AIoT service.
[0044] In some embodiments, the information of the AIoT reader or AIoT device includes: the location information of the AIoT reader or AIoT device. In S412, the first RAN node forwarding the AIoT service request to the second RAN node may include: the first RAN node forwarding the AIoT service request to the second RAN node based on the location information of the AIoT reader or AIoT device, or whether the second RAN node supports AIoT services, wherein the second RAN node supports AIoT services. For example, if the first RAN node is MN, MN can interact with surrounding secondary nodes (SNs) to select an SN that supports AIoT services as the second RAN node. Alternatively, based on the location information of the AIoT reader or AIoT device, an SN whose coverage area includes the location of the AIoT reader or AIoT device and which supports AIoT services can be selected as the second RAN node.
[0045] In one embodiment, the AIoT reader or the AIoT device is located within the coverage area of the second RAN node. The location of the AIoT reader or the AIoT device can be determined using the location information of the AIoT reader or the AIoT device.
[0046] In the above embodiments, the first RAN node can select a second RAN node whose coverage area includes the location of the AIoT reader or the AIoT device or supports AIoT services, based on the location information of the AIoT reader or the AIoT device, and forward the AIoT service request to the second RAN node. This ensures that the second RAN node can page the AIoT reader or the AIoT device, thus ensuring the successful execution of subsequent AIoT services.
[0047] In some implementations, in the above embodiments, after S412, the method may further include the following steps: Step 1: The first RAN node receives feedback information sent by the second RAN node in response to the AIoT service request; Step 2: If the feedback information indicates that the second RAN node accepts the AIoT service request, the first RAN node and the second RAN node negotiate to configure AIoT service resources for the AIoT reader or AIoT device.
[0048] In the above implementation, when the first RAN node receives feedback information instructing the second RAN node to accept the AIoT service request, it negotiates with the second RAN node to configure AIoT service resources for the AIoT reader or AIoT device, thereby enabling the AIoT reader or AIoT device to use the AIoT service resources to transmit AIoT service data and ensuring the successful execution of the AIoT service.
[0049] In the above embodiments, optionally, when the first RAN node and the second RAN node negotiate the configuration of AIoT service resources for the AIoT reader or AIoT device, they can negotiate to stagger the working time of the air interface (Uu) and AIoT to reduce interference. For example, the first RAN node and the second RAN node negotiate the time division multiplexing (TDM) mode to configure the AIoT service resources on time units without air interface transmission.
[0050] In the above embodiments, optionally, the feedback information may include at least one of the following: 1) Fourth information, the fourth information being used to instruct the second RAN node to accept the AIoT service request; 2) Fifth information, which is used to instruct the second RAN node to agree to configure resources for the AIoT reader or AIoT device; 4) Sixth information, which is used to indicate the AIoT service resources that the second RAN node recommends to be configured for the AIoT reader or AIoT device.
[0051] The feedback information provided above allows the first RAN node to know the specific details of the second RAN node's acceptance of the AIoT service request.
[0052] In some embodiments, prior to S410, the method may further include: the first RAN node sending information about a second RAN node related to the first RAN node to the core network node. For example, the first RAN node may send information about an SN node related to the first RAN node to the core network node, or the first RAN node may send information about neighboring RAN nodes of the first RAN node to the core network node. Optionally, the information about the second RAN node may include at least one of the following: location information, identification information, address information, and capability information of the second RAN node, which is not limited in specific embodiments of this application.
[0053] In the above embodiments, since the first RAN node sends the information of the second RAN node to the core network node in advance, the core network node can directly select the second RAN node to receive the AIoT service request when sending it, and transparently forward the AIoT service request to the second RAN node through the first RAN node. Therefore, in some implementations of these embodiments, S412 may include: the first RAN node forwarding the AIoT service request to the second RAN node based on the destination address of the AIoT service request. Here, the destination address is the address corresponding to the second RAN node; therefore, after receiving the AIoT service request, the first RAN node transparently forwards the AIoT service request to the second RAN node.
[0054] In some embodiments of the above examples, after S412, the method may further include the following steps: Step 1: The first RAN node receives feedback information sent by the second RAN node in response to the AIoT service request; Step 2: The first RAN node forwards the feedback information to the core network node.
[0055] In the above implementation, after receiving the AIoT service request, the second RAN node can send feedback information to the core network node through the first RAN node, and the first RAN node forwards the feedback information to the core network node.
[0056] In some implementations, when the feedback information indicates that the second RAN node accepts the AIoT service request, the first RAN node and the second RAN node negotiate the AIoT service resources configured for the AIoT reader or AIoT device. Then, the first RAN node can send confirmation information to the core network node, wherein the confirmation information confirms that the first RAN node and the second RAN node have completed the negotiation. Through these implementations, the first RAN node can negotiate the AIoT service resources configured for the AIoT reader or AIoT device with the second RAN node, thereby enabling the transmission of AIoT services using these AIoT service resources. Furthermore, the first RAN node can send confirmation information to the core network node, allowing the core network node to know that the first RAN node and the second RAN node have completed the negotiation, and thus execute the AIoT service.
[0057] In some implementations, when the feedback information indicates that the second RAN node rejects the AIoT service request, the feedback information includes at least one of the following: 1) First indication information, wherein the first indication information is used to instruct the second RAN node to reject the AIoT service request; 2) Second indication information, which is used to instruct the second RAN node to refuse to configure resources for the AIoT reader or AIoT device; 3) Third indication information, which is used to indicate the reason for the second RAN node's rejection.
[0058] Through the above implementation method, the core network node can know the specific circumstances under which the second RAN node rejects the above AIoT service request, and then can reselect the second RAN node to send the AIoT service request.
[0059] In some implementations, when the feedback information instructs the second RAN node to accept the AIoT service request, the content of the feedback information is similar to that in the above embodiments and may include at least one of the following: 1) Fourth information, the fourth information being used to instruct the second RAN node to accept the AIoT service request; 2) Fifth information, which is used to instruct the second RAN node to agree to configure resources for the AIoT reader or AIoT device; 4) Sixth information, which is used to indicate the AIoT service resources that the second RAN node recommends to be configured for the AIoT reader or AIoT device.
[0060] In the above embodiments, optionally, after the first RAN node and the second RAN node negotiate the AIoT service resources configured for the AIoT reader or AIoT device, the method further includes one of the following: 1) The first RAN node pages the AIoT reader or AIoT device through the second RAN node. In some embodiments, the AIoT service request sent by the core network device may include paging information, or the core network device may send paging information to the first RAN node in addition to the AIoT service request. The first RAN node may then page the AIoT reader or AIoT device through the second RAN node based on the paging information.
[0061] 2) The first RAN node forwards the paging information to the second RAN node, wherein the paging information instructs the second RAN node to initiate a paging message for the AIoT reader or AIoT device. In some embodiments, if the second RAN node has paging capabilities, the first RAN node can forward the paging information to the second RAN node, which then initiates a paging message for the AIoT reader or AIoT device. For example, the core network node can transparently forward the paging information to the second RAN node through the first RAN node, and the second RAN node can then initiate a paging message for the AIoT reader or AIoT device based on this paging information.
[0062] In the above embodiments, the first RAN node can be MN, and the second RAN node can be SN.
[0063] In one implementation, the first RAN node can be the MN in a dual-connection or multi-connection configuration, and the second RAN node can be the SN in a dual-connection or multi-connection configuration.
[0064] In the first embodiment, S412 may include: the first RAN node paged the AIoT reader or AIoT device and forwarded the AIoT service request to an adjacent second RAN node. For example, when the AIoT reader or AIoT device is in Radio Resource Control (RRC) idle state or RRC-INACTIVE state, the first RAN node forwards the AIoT service request to the adjacent second RAN node, which then pages the AIoT reader or AIoT device. Simultaneously, the first RAN node may also page the AIoT reader or AIoT device. In these embodiments, the first RAN node can page the AIoT reader or AIoT device and forward the AIoT service request to the adjacent second RAN node, which then pages the AIoT reader or AIoT device. Therefore, it is possible to ensure that the AIoT reader or AIoT device is paged as much as possible.
[0065] In the second embodiment, S412 may include: if the first RAN node fails to page the AIoT reader or AIoT device, it forwards the AIoT service request to an adjacent second RAN node. For example, if the AIoT reader or AIoT device is in RRC-idle or RRC-INACTIVE mode, the first RAN node pages the AIoT reader or AIoT device. If the AIoT reader or AIoT device does not respond to the first RAN node's page, the first RAN node forwards the AIoT service request to an adjacent second RAN node, which then pages the AIoT reader or AIoT device. In these embodiments, the first RAN node can forward the AIoT service request to an adjacent second RAN node if pager failure occurs, ensuring that the AIoT reader or AIoT device is paged.
[0066] In the above embodiments, the failure of the first RAN node to page the AIoT reader or AIoT device may include the following two situations: 1) After the first RAN node sends a paging message, it does not receive a paging response from the AIoT reader or AIoT device within a specified time; 2) After the first RAN node sends a paging message, it receives a response from the AIoT reader or AIoT device within a specified time, but the paging fails for some reason, such as the paging failure caused by an uplink collision when the AIoT reader or AIoT device responds to the paging.
[0067] In the third embodiment, S412 may include: when the AIoT reader or AIoT device is in an inactive state, the first RAN node directly forwards the AIoT service request to an adjacent second RAN node. For example, when the AIoT reader or AIoT device is in an RRC inactive state, the first RAN node directly forwards the AIoT service request to an adjacent second RAN node, which then pages the AIoT reader or AIoT device to ensure that the AIoT reader or AIoT device is paged.
[0068] In the first to third embodiments described above, optionally, after forwarding the AIoT service request to the adjacent second RAN node, the method further includes: the first RAN node negotiating with the second RAN node to allocate AIoT service resources for the AIoT reader or AIoT device. Through this optional implementation, the first RAN node can negotiate with the second RAN node to allocate AIoT service resources for the AIoT reader or AIoT device, thereby enabling subsequent transmission of AIoT service data based on these AIoT service resources.
[0069] In the above embodiments, optionally, the first RAN node and the second RAN node negotiate the AIoT service resources configured for the AIoT reader or AIoT device, including one of the following: 1) The first RAN node and the second RAN node negotiate to configure AIoT service resources for the AIoT reader or AIoT device through SRB 3; 2) The first RAN node and the second RAN node negotiate to configure AIoT service resources for the AIoT reader or AIoT device by splitting SRB 1; 3) The first RAN node and the second RAN node negotiate to configure AIoT service resources for the AIoT reader or AIoT device through a dedicated SRB.
[0070] Through the above optional implementation methods, the first RAN node and the second RAN node can negotiate the way to configure AIoT service resources for the AIoT reader or AIoT device.
[0071] Based on the same technical concept, this application also provides another service request method. This method is executed by the aforementioned second RAN node.
[0072] It should be noted that the following embodiments mainly describe the operation of the second RAN node. For other matters not covered, please refer to the relevant description of method 400 above.
[0073] Figure 5 This diagram illustrates another flowchart of a service request method provided in an embodiment of this application, whereby the method 500 can be executed by a second RAN node. In other words, the method can be executed by software or hardware installed on the second RAN node. Figure 5 As shown, the method mainly includes the following steps.
[0074] S510, the second RAN node receives the AIoT service request forwarded by the first RAN node, wherein the AIoT service request carries information about an AIoT reader or AIoT device.
[0075] The first RAN node can forward AIoT service requests to the second RAN node using the various implementation methods described in method 400 above. For details, please refer to the relevant descriptions in method 400 above, which will not be repeated here.
[0076] S512, the second RAN node pages the AIoT reader or AIoT device performing the AIoT service.
[0077] In this embodiment of the application, after receiving an AIoT service request, the second RAN node can page the AIoT reader or AIoT device that performs the AIoT service, and then perform the AIoT service through the paged AIoT reader or AIoT device to ensure the successful execution of the AIoT service.
[0078] In some embodiments, after S510, the method may further include: the second RAN node sending feedback information regarding the AIoT service request. In these embodiments, the second RAN node can use this feedback information to indicate whether it accepts the AIoT service request.
[0079] Optionally, if the feedback information indicates that the second RAN node accepts the AIoT service request, the feedback information may include at least one of the following: 1) Fourth information, the fourth information being used to instruct the second RAN node to accept the AIoT service request; 2) Fifth information, which is used to instruct the second RAN node to agree to configure resources for the AIoT reader or AIoT device; 4) Sixth information, which is used to indicate the AIoT service resources that the second RAN node recommends to be configured for the AIoT reader or AIoT device.
[0080] Optionally, if the feedback information indicates that the second RAN node rejects the AIoT service request, the feedback information may include at least one of the following: 1) First indication information, which is used to instruct the second RAN node to reject the AIoT service request; 2) Second indication information, which is used to instruct the second RAN node to refuse to configure resources for the AIoT reader or AIoT device; 3) Third indication information, which is used to indicate the reason for the second RAN node's rejection.
[0081] In some embodiments, the method may further include: when the feedback information indicates that the second RAN node accepts the AIoT service request, the second RAN node negotiates with the first RAN node to allocate AIoT service resources to the AIoT reader or AIoT device. By negotiating the AIoT service resources allocated to the AIoT reader or AIoT device, AIoT services can be subsequently transmitted using the allocated AIoT service resources.
[0082] In some implementations of these embodiments, the AIoT service resources negotiated between the second RAN node and the first RAN node for the AIoT reader or AIoT device may include one of the following: 1) The second RAN node negotiates with the first RAN node to configure AIoT service resources for the AIoT reader or AIoT device through SRB 3; 2) The second RAN node negotiates with the first RAN node to configure AIoT service resources for the AIoT reader or AIoT device by splitting SRB 1; 3) The second RAN node negotiates with the first RAN node to configure AIoT service resources for the AIoT reader or AIoT device through a dedicated SRB.
[0083] During the aforementioned negotiation process, the AIoT service resources negotiated between the second RAN node and the first RAN node can stagger the working hours of the Uu port and AIoT, thereby reducing interference.
[0084] In some embodiments, S512 may include: the second RAN node forwarding a paging message sent by the first RAN node, wherein the paging message is used to page the AIoT reader or AIoT device. In these embodiments, the first RAN node can page the AIoT reader or AIoT device through the second RAN node, thereby avoiding the problem that AIoT service requests cannot reach the AIoT reader or AIoT device because the first RAN node cannot directly write to the AIoT reader or AIoT device for communication.
[0085] In other embodiments, S512 may include: the second RAN node receiving paging information sent by the first RAN node, and initiating a paging message for the AIoT reader or AIoT device based on the paging information. In these embodiments, the first RAN node may forward the paging information sent by the core network node to the second RAN node, which then initiates the paging message for the AIoT reader or AIoT device. The paging information may be transparently forwarded by the core network node through the first RAN node, or the first RAN node may select the second RAN node to forward the paging information based on the received paging information.
[0086] In some embodiments, S512 may include: the second RAN node initiating a paging message for the AIoT reader or AIoT device based on the received AIoT service request. In these embodiments, the AIoT service request may carry paging information for the AIoT reader or AIoT device. The first RAN node may forward the AIoT service request to the second RAN node after receiving it, and the second RAN node may initiate paging of the AIoT reader or AIoT device. In these embodiments, the first RAN node may initiate a paging message for the AIoT reader or AIoT device based on the AIoT service request, or it may directly forward the AIoT service request. The first RAN node may forward the AIoT service request to the second RAN node if paging of the AIoT reader or AIoT device fails, or it may forward the AIoT service request to the second RAN node before receiving a paging response from the AIoT reader or AIoT device. For details, please refer to the relevant description in method 400 above.
[0087] In some embodiments, after S512, the method may further include: receiving a paging response sent by the AIoT reader or AIoT device, and forwarding AIoT service data between the core network node and the AIoT reader or AIoT device. In these embodiments, after receiving the paging response sent by the AIoT reader or AIoT device, the second RAN node can forward the AIoT service data between the core network node and the AIoT reader or AIoT device through the second RAN node; alternatively, the second RAN node may directly forward the AIoT service data between the core network node and the AIoT reader or AIoT device to the core network node and the AIoT reader or AIoT device, depending on the capabilities of the second RAN node.
[0088] In this embodiment, taking a DC scenario as an example, assuming an AIoT reader (e.g., an AIoT UE reader) or AIoT device is covered by the secondary node SN1, the CN node (e.g., an AIoT function node, AMF node) initiates an AIoT service request to the MN. The MN can then interact with surrounding secondary nodes SN based on the location information of the AIoT reader or AIoT device, forwarding the AIoT service request to SN1 and negotiating with SN1 to configure AIoT service resources for the AIoT reader or AIoT device. The MN can select an SN based on whether the SN supports AIoT services. Figure 6 This diagram illustrates an interaction flow for a business request method, such as... Figure 6 As shown, the interaction flow of the business request method in this scenario includes the following steps: S601, the CN node sends a service request to the MN, which carries information about the AIoT reader or AIoT device.
[0089] S602, MN interacts with the surrounding SN and selects SN1.
[0090] Optionally, MN can select an SN based on the location information of the AIoT reader or AIoT device or whether the SN supports AIoT services. The selected SN1 can be a SN whose coverage includes the location of the AIoT reader or AIoT device or a SN that supports AIoT services.
[0091] S603, MN forwards the above service request to SN1.
[0092] The service request may include AIoT service resource request information, which may include one of the following: 1) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via SRB 3; 2) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via split SRB 1; 3) Information instructing the SN to configure AIoT service resources for AIoT readers or AIoT devices via the new SRB.
[0093] S604, SN1 decides to respond to this service request.
[0094] After receiving a service request from MN, SN1 decides to respond to the service request. SN1 may send feedback information back to MN. Optionally, the feedback information from SN1 may include at least one of the following: 1) Information instructing SN to agree to MN's business requests; 2) Information instructing the SN to agree to configure AIoT radio resources for the AIoT reader or AIoT device; 3) Suggestions from SN1 for configuring AIoT wireless resources to MN, such as SN1 suggesting a configuration method similar to that for SRB.
[0095] S605, MN and SN1 negotiate to configure AIoT service resources for AIoT readers or AIoT devices.
[0096] The negotiation of AIoT service resources between MN and SN1 nodes may include how to stagger the working hours of Uu and AIoT to reduce interference, such as MN and SN1 negotiating the TDM pattern.
[0097] S606, MN pages AIoT readers or AIoT devices via SN1.
[0098] Once the SN and MN have agreed, the MN can page the AIoT reader or AIoT device through SN1 at the request of the CN node. Alternatively, if SN1 has paging capabilities, the CN can transparently forward paging information to SN1 through the MN, and SN1 can then page the AIoT reader or AIoT device. For example, the MN can feed back the selected SN1 information to the core network node, and the core network node can transparently forward the paging information to SN1 through the MN. Or, the MN can send the received paging information to SN1.
[0099] S607, SN1 receives the paging response from the AIoT reader or AIoT device, and the CN node and the AIoT reader or AIoT device can forward AIoT service data through MN and SN1.
[0100] In this embodiment, taking a DC scenario as an example, assuming the AIoT reader (e.g., AIoT UE reader) or AIoT device is covered by the secondary node SN1, the MN can feed back SN information related to the MN to the CN node (e.g., AIoT function, AMF), such as SN identifier (ID), SN cell information, SN address, etc. When the CN node initiates an AIoT service request to the AIoT reader or AIoT device, the CN node can directly forward the AIoT service request to the SN1 connected to the MN (transparently forwarding it to SN1 to the MN). The AIoT service request sent by the CN node to SN1 may include request information for configuring AIoT service resources for the AIoT reader or AIoT device. The CN node selects SN1 based on whether the SN supports AIoT services. Figure 7This illustrates another interactive flow diagram for a business request method, such as... Figure 7 As shown, the interaction flow of the business request method in this scenario includes the following steps: S701, the MN feeds back relevant SN information of the MN to the CN node, such as SN ID, SN address and SN cell information.
[0101] S702, the CN node transparently forwards AIoT service requests to SN1 through the MN. The AIoT service request carries information about the AIoT reader or AIoT device.
[0102] Optionally, the CN node can select an SN based on the location information of the AIoT reader or AIoT device, or whether the SN supports AIoT services. The selected SN1 can be a SN whose coverage includes the location of the AIoT reader or AIoT device or a SN that supports AIoT services.
[0103] The AIoT service request may carry AIoT service resource request information, which may include one of the following: 1) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via SRB 3; 2) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via split SRB 1; 3) The AIoT reader or AIoT device SN configures AIoT service resources for the AIoT reader or AIoT device through the new SRB.
[0104] S703, SN1 decides to respond to this service request.
[0105] S704, SN1 transparently forwards SN1's feedback information (ACK or NACK) to the CN node through MN.
[0106] After SN1 receives the service request sent by MN, SN1 decides to respond to the service request. SN1 can transparently forward the feedback information to the CN node.
[0107] Optionally, if SN1 rejects the request initiated by the CN node, SN1's feedback information shall include at least one of the following: 1) Information instructing the SN to reject the service request of the CN node, wherein the information instructing the SN to reject the request of the CN node is forwarded to the CN node through the MN.
[0108] 2) Instructs the SN to refuse to configure AIoT radio resources for the AIoT reader or AIoT device; 3) Reasons for rejection, such as insufficient SN1 resources, the AIoT reader or AIoT device not being covered by SN, or the AIoT reader or AIoT device not responding to paging.
[0109] Optionally, if SN1 accepts the request initiated by MN, then SN1's feedback information includes at least one of the following: 1) Information instructing the SN to agree to the CN node's service request; 2) Instruct the SN to agree to configure AIoT radio resources for the AIoT reader or AIoT device.
[0110] S705, MN and SN1 negotiate to configure AIoT service resources for AIoT readers or AIoT devices.
[0111] The negotiation of AIoT service resources between MN and SN1 nodes may include how to stagger the working hours of Uu and AIoT to reduce interference, such as MN and SN1 negotiating the TDM pattern.
[0112] S706, MN sends a confirmation to the CN node regarding the negotiation with SN1.
[0113] S707, MN pages AIoT readers or AIoT devices via SN1.
[0114] Once the SN and MN have agreed, the MN can page the AIoT reader or AIoT device through SN1 at the request of the CN node. Alternatively, if SN1 has paging capabilities, the CN can transparently forward paging information to SN1 through the MN, and SN1 can then page the AIoT reader or AIoT device.
[0115] S708, SN1 receives the paging response from the AIoT reader or AIoT device, and the CN node and the AIoT reader or AIoT device can forward AIoT service data through MN and SN1.
[0116] In this embodiment, when an AIoT reader (e.g., an AIoT UE reader) or AIoT device is covered by BS2, the CN node initiates an AIoT service request to BS1. The AIoT service request may include information about the AIoT reader or AIoT device and information about the neighboring BS2. The AIoT service request may also include AIoT service resource request information. Figure 8 This illustrates another interactive flow diagram for a business request method, such as... Figure 8 As shown, the interaction flow of the business request method in this scenario includes the following steps: S801, the CN node sends a service request to BS1, which carries information about the AIoT reader or AIoT device.
[0117] S802, BS1 paging AIoT reader or AIoT device.
[0118] This step is optional.
[0119] S803, BS1 decides to forward the AIoT service request to BS2.
[0120] Optionally, BS1 may decide to forward the AIoT service request to BS2 if it does not receive a paging response from the AIoT reader or device after paging it. Alternatively, BS1 may decide to forward the AIoT service request to BS2 after paging the AIoT reader or device but before determining whether the AIoT reader or device has responded to the paging. Or, BS1 may directly decide to forward the AIoT service request upon receiving it without initiating paging.
[0121] For example, when the UE reader is processing the RRC_IDLE state, and BS1 receives an AIoT service request initiated by the CN node, BS1's behavior may include one of the following: 1) BS1 pages the AIoT reader or AIoT device. If the AIoT reader or AIoT device does not respond to the BS1 page, BS1 forwards the AIoT service request to BS2, and BS2 can also page the AIoT reader or AIoT device.
[0122] 2) BS1 can page AIoT readers or AIoT devices. At the same time, BS1 can forward AIoT service requests to BS2, and BS2 can also page AIoT readers or AIoT devices.
[0123] When the UE reader or AIoT device is in RRC_INACTIVE mode, the CN node sends a service request to the gNB BS1 to which the UE reader is anchored. When BS1 receives the service request initiated by the CN node, BS1's behavior may include one of the following: 1) BS1 pages the UE reader via gNB BS2 and forwards the AIoT service request to BS2. BS2 then pages the UE reader.
[0124] 2) BS1 pages the AIoT reader or AIoT device. If the AIoT reader or AIoT device does not respond to the BS1 page, BS1 forwards the AIoT service request to BS2, and BS2 can also page the AIoT reader or AIoT device.
[0125] 3) BS1 can page AIoT readers or AIoT devices. At the same time, BS1 can forward AIoT service requests to BS2, and BS2 can also page AIoT readers or AIoT devices.
[0126] S804, BS1 forwards the above service request to BS2.
[0127] The service request may include AIoT service resource request information, which may include one of the following: 1) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via SRB 3; 2) Information instructing the SN to configure AIoT service resources for the AIoT reader or AIoT device via split SRB 1; 3) Information instructing the SN to configure AIoT service resources for AIoT readers or AIoT devices via the new SRB.
[0128] S805, BS1 and BS2 negotiate the resources configured for AIoT readers or AIoT devices.
[0129] When negotiating AIoT service resources between BS1 and BS2 nodes, it may include how to stagger the working hours of Uu and AIoT to reduce interference, such as BS1 and BS2 negotiating TDM patterns.
[0130] S806, BS2 paging AIoT reader or AIoT device.
[0131] S807, BS2 receives the paging response from the AIoT reader or AIoT device, and the CN node and the AIoT reader or AIoT device can forward AIoT service data through BS1 or BS2.
[0132] In the technical solution provided in this application embodiment, when RAN node 1 receives an AIoT service request from CN node, RAN node 1 forwards the AIoT service request to the adjacent RAN node 2 and negotiates with RAN node 2 to execute the AIoT service request. The technical solution provided in this application embodiment can solve the problem of how to complete the AIoT service request issued by CN node in scenarios such as (NG)EN-DC or RAN node 1 being unable to page the AIoT reader / writer or AIoT device, thus improving the applicability of AIoT services.
