Description

Internet of Things (IoT) communication methods and wireless communication devices Technical Field

[0001] This invention relates to the field of communication systems, and more specifically, to an Internet of Things (IoT) communication method and a wireless communication device. Background Technology

[0002] With the development of wireless communication technology, there is a growing desire to integrate wireless communication systems with various vertical industries such as logistics, manufacturing, transportation, and energy. For example, wireless communication systems can be integrated with industrial wireless sensor networks (IWSNs), smart logistics and smart warehousing, and smart home networks. Currently, most existing wireless communication devices are powered by batteries that require manual replacement or recharging. However, it is impractical to power all IoT devices with manually replaceable or rechargeable batteries, leading to high maintenance costs, serious environmental problems, and even safety hazards for certain use cases (such as wireless sensors in the power and oil industries).

[0003] Therefore, terminal devices typically need to have characteristics such as low cost, small size, maintenance-free operation, and long lifespan. To meet these conditions, new Internet of Things (IoT) technologies are needed to support battery-free devices without energy storage capabilities or devices with energy storage functions that do not require manual replacement or charging.

[0004] Ambient Internet of Things (AIoT) devices refer to IoT devices that use various environmental energy sources, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. AIoT devices may have no energy storage capacity or very limited energy storage capacity (e.g., using capacitors with a capacitance of tens of microfarads). Compared to existing IoT devices, AIoT devices have many advantages, including no need for conventional batteries, no maintenance, small size, low complexity and low cost, and long lifespan.

[0005] However, when a base station or user equipment (UE) acts as a reader to connect to multiple AIoT devices, the ALOHA random access mechanism is often used. Therefore, a single paging process cannot successfully connect all AIoT devices to the base station or UE. Multiple paging attempts are required to ensure successful connection for all AIoT devices. However, during repeated paging, if a UE that has already successfully connected attempts to connect again, it incurs additional signaling overhead. Therefore, how to efficiently improve the paging process is a technical problem that needs to be solved.

[0007] One objective of this invention is to provide an Internet of Things (IoT) communication method and wireless communication device to solve the aforementioned technical problems.

[0012] A fifth aspect of the present invention provides a method for Internet of Things (IoT) communication, the method being executed in a user equipment (UE) / reader, comprising: receiving location information sent by a base station to obtain location data of the UE; when the UE / reader detects that the location data does not belong to the current paging area, sending an update paging area request to the base station; and updating the paging area ID of the UE / reader according to the update paging area information sent by the base station.

[0013] A sixth aspect of the present invention provides a method for Internet of Things (IoT) communication, the method being executed in a base station, comprising: when a configuration change of the base station or core network equipment is detected, receiving an update paging area request sent by the core network equipment, wherein the update paging area request includes a UE ID / reader ID corresponding to a UE / reader and a new paging area ID corresponding to the UE / reader; and sending the new paging area ID of the UE / reader to the UE / reader to update the paging area ID of the UE / reader.

[0014] A seventh aspect of the present invention provides a method for Internet of Things (IoT) communication, the method being executed in a base station, comprising: receiving a first location report sent by a reader, wherein the first location report includes an AIOT device ID of the AIOT device, and the AIOT device ID is associated with a reader ID of the reader when the AIOT device in the environment accesses the reader; and sending a second location report to a core network device, wherein the second location report includes the AIOT device ID of the AIOT device and the reader ID of the reader.

Beneficial effects

[0022] Compared to existing technologies, embodiments of the present invention provide a method for Internet of Things (IoT) communication. Through the technical solution of one embodiment of the present invention, when a base station or user equipment (UE) acts as a reader and connects to multiple environmental devices, if a single paging attempt fails to successfully connect all AIoT devices to the base station 200 or UE, successfully connected UEs will not reconnect during repeated paging processes, thus reducing additional signaling overhead.

[0023] According to another embodiment of the present invention, when a reader sends a paging message to multiple AIoT devices, the paging message includes a mapping table of multiple device association identification IDs and multiple random access IDs. The mapping table records the mapping relationship between the multiple device association IDs and the multiple random access IDs. The random access IDs indicate the order in which the corresponding device IDs access the reader in different time slots. Therefore, a single paging process can allocate multiple AIoT devices to access the reader in different time slots, allowing multiple AIoT devices to access the reader without conflict. This avoids repeated paging and re-access, and has the beneficial effect of reducing additional signaling overhead.

[0024] According to another embodiment of the present invention, when the paging area changes due to the movement of the AIoT device, the AIoT device can notify and update the paging area in real time. Therefore, the paging area corresponding to the AIoT device can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0025] Through another embodiment of the technical solution of the present invention, through embodiments of updating the paging area ID initiated by the UE and embodiments of updating the paging area ID initiated by the base station or core network equipment, when the paging area ID changes, the UE, base station, and core network equipment 30 can update the paging area ID in real time. Therefore, the paging area ID corresponding to the AIoT device 40 can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0026] In another embodiment of the present invention, the reader updates the association between the reader ID and the AIoT device ID to the core network device, and the core network device uses the reader ID to find the AIoT device in the paging message. Because the reader ID and the AIoT device ID are associated and the core network device stores the mapping relationship between the reader ID and the AIoT device ID, the paging message sent by the core network device to the base station can include the reader ID. This allows the base station 200 to efficiently determine which reader sent the AIoT device ID through the reader ID in the paging message, thus improving paging efficiency.

The base station 200 can provide communication coverage for a specific geographical area and can communicate with the user equipment 10 located within that coverage area.

[0047] The core network 130 can be an IP mobile communication network operated by a mobile communication operator. For example, the core network 130 can be the core network used by a mobile communication operator to operate and manage the wireless communication system 100, or it can be the core network used by a virtual mobile communication operator such as a Mobile Virtual Network Operator (MVNO). The core network 130 can be connected to the base station 200 as a relay device for transmitting user data. The user equipment 10 transmits and receives user data via the core network 130.

For example, UE 10 may communicate using point-to-point (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or similar protocols), mesh networks, or similar networks, or combinations thereof.

The wireless interface protocol layer can be implemented in processors 11, 201, 301, and 401. Each memory 12, 202, 302, and 402 can store various programs and information to cooperate with the operation of the connected processor. Each transceiver 13, 203, 303, 403 is coupled to a processor for transmitting and / or receiving radio or wired signals. Base station 200 may be one of an eNB, gNB, access point (AP), transmit-receive point (TRP), or other types of wireless nodes, and may configure wireless resources for UE 10. In the following embodiments, reader 14 and reader 204 may be chips integrated into UE 10 and base station 200, or may be program code stored in memory 12 and 202 executed by processors 11 and 201 to read data or signals from AIoT device 40. In other embodiments, the reader may also refer to user equipment 10 or base station 200 used to read data or signals from AIoT device 40. For ease of explanation, the reader mentioned in the embodiments of this application may be user equipment 10 or base station 200 used to read data or signals from AIoT device 40, or a chip integrated into UE 10 and base station 200.

[0053] Each processor 11, 201, 301, 401 may include an application-specific integrated circuit (ASIC), other chipsets, logic circuits, and / or data processing devices. Each memory 12, 202, 302, 402 may include read-only memory (ROM), random access memory (RAM), flash memory, memory cards, storage media, and / or other storage devices.

[0054] In this embodiment, the core network device 300 can be a node in the LTE core network or the 5G core network 130, including User Plane Function (UPF), Session Management Function (SMF), Mobility Management Function (AMF), Unified Data Management (UDM), Policy Control Function (PCF), Control Plane (CP) / User Plane (UP) Separation (CUPS), Authentication Server (AUSF), Network Slice Selection Function (NSSF), and Network Open Function (NEF).

[0055] The AIoT device 40 can be a wireless communication device suitable for short-range, low-speed communication. The AIoT device 40 can possess technologies such as radio frequency energy harvesting, backscatter communication, and low-power computing to achieve the advantage of not requiring a power supply. The core of radio frequency energy harvesting is converting radio frequency energy into direct current. This energy can be stored in batteries or capacitors, or it can be collected and directly used to drive logic circuits, digital chips, or sensors to complete functions and applications such as modulation and transmission of backscattered signals, and acquisition and processing of sensor information.

[0056] The AIoT device 40, as a zero-power device, can be used in scenarios such as wireless industrial sensor networks, smart warehousing and logistics, and smart homes. The AIoT device 40 can be a passive zero-power device. This type of passive zero-power device does not require an internal battery. When the passive zero-power device approaches a network device (such as an RFID reader), it is within the near-field range formed by the antenna radiation of the network device. Therefore, the antenna of the passive zero-power device generates an induced current through electromagnetic induction, which drives the low-power chip circuitry of the zero-power device. This enables demodulation of the forward link signal and modulation of the backward link signal. The RF and baseband circuits of the passive zero-power device are very simple, requiring no LNA (Low Noise Amplifier), PA (Power Amplifier), ADC (Analog-to-Digital Converter), or other similar components. The AIoT device 40 can also use an RF energy harvesting module to harvest radio wave energy and store the harvested energy in an energy storage unit (such as a capacitor). After acquiring energy, the energy storage unit can drive the low-power chip circuitry of zero-power devices. This enables the demodulation of forward link signals and the modulation of backward link signals. Therefore, AIoT devices 40 have advantages such as small size, light weight, low price, and long lifespan.

[0057] Example 1

[0058] For ease of explanation, the paging message mentioned in this application may also be referred to as, but is not limited to, initial triggering message, paging likely message, or AIoT paging message, and the above terms are also within the scope of this application.

[0059] Please refer to Figures 1 and 2. As shown in Figure 1, base station 200 can communicate with multiple user equipments 10 located within its coverage area. Each user equipment 10 communicates with multiple environmental Internet of Things (AIoT) devices 40 located within its respective control area. For example, when an AIoT device 40 is within the coverage area of ​​user equipment 10 (e.g., the coverage area of ​​UE1), user equipment 10 can access AIoT devices 40 located within the coverage area of ​​UE1. When an AIoT device 40 is within the coverage area of ​​multiple user equipments 10 (e.g., the coverage areas of UE1 and UE2), user equipment 10 can access AIoT devices 40 located within the coverage areas of both UE1 and UE2. In this embodiment, multiple AIoT devices 40 located within the coverage area of ​​UE1 can be considered as the same group, or multiple AIoT devices 40 located within the coverage area of ​​the same base station 10 can be considered as the same group. This embodiment is applicable to group paging scenarios.

[0060] When multiple AIoT devices 40 in a group receive a group paging message, they will attempt to connect randomly. However, since the time slots randomly selected by each AIoT device 40 may conflict, the AIoT devices 40 that failed to connect need to try again in the next paging round. However, since the paging message carries the group ID, the second paging message also carries the group ID, causing the AIoT devices 40 that successfully connected the first time to initiate another random connection. Therefore, this application proposes the following solution to address this problem.

[0061] Option 1: Please refer to Figure 3, which is a flowchart illustrating a method for performing Internet of Things (IoT) communication in an AIoT device according to an embodiment of the present invention. The method includes steps 300-306.

[0062] In step 300, the AIoT device 40 receives a first paging message sent by the reader, wherein the first paging message includes a paging ID.

[0063] In step 302, when the first paging message is received, the reader is accessed.

[0064] In step 304, when the AIoT device 40 fails to connect to the reader after receiving the first paging message, it receives a second paging message sent by the reader, wherein the second paging message includes the paging ID.

[0065] In step 306, when the paging ID of the second paging message is the same as the paging ID of the first paging message, access to the reader is stopped.

[0066] It is worth noting that the above steps can be performed sequentially or not sequentially. In addition, only some steps can be performed instead of all steps each time.

[0067] Furthermore, the first and second paging messages sent by the reader can contain a group ID and a paging ID, with the group ID bound to the paging ID. If the reader sends the same paging ID and group ID in two or more consecutive paging messages, then the AIoT devices 40 that have already successfully connected do not need to connect again; only the AIoT devices 40 that failed to connect last time need to connect.

[0068] Option 2: The first paging message sent by the reader (i.e., the first round of paging messages) includes a group ID and a paging ID, where the group ID is bound to the paging ID. If the reader sends the same paging ID and group ID in two or more consecutive paging messages, and the second paging message (i.e., the paging message sent after the first round of paging messages) carries additional re-access indicator information, when the paging ID of the second paging message is the same as the paging ID of the first paging message, the device re-accesses the reader based on the re-access indicator information. Therefore, AIoT devices 40 that have already successfully connected on the first attempt do not need to re-access; only AIoT devices 40 that failed to connect on the first attempt need to re-access.

[0069] Option 3: The reader sends a paging timer (paging_timer) in the first paging message. When the AIoT device 40 receives this paging timer, it starts the timer to set the paging time. If the timer exceeds the paging time and the paging ID of the second paging message is the same as the paging ID of the first paging message, the AIoT device 40 considers it to be the same paging round, and the AIoT device 40 that has already successfully connected does not need to connect again.

[0070] Option 4: The reader does not need to be configured with a timer. The timer is bound to the number of time slots allocated in this round of random access. For example, if the number of random access time slots allocated in this round is 100, then the paging time can be a delay of 100 x 2 time slots.

[0071] According to the technical solution of Embodiment 1, when the base station 200 or user equipment 10 is connected to multiple environmental devices 40 as a reader, if a paging does not successfully connect all AIoT devices 40 to the base station 200 or user equipment 10, the UEs that have successfully connected will not connect again during repeated paging, thus reducing additional signaling overhead.

[0072] Example 2

[0073] Traditional AIoT access uses a time slot to randomly generate a random access ID via the ALOHA mechanism, but this can lead to conflicts. This embodiment uses a paging message to assign a random access ID to all AIoT devices.

[0074] Please refer to Figure 4, which is a flowchart illustrating a method for performing IoT communication on a reader according to another embodiment of the present invention. The method includes steps 400-402. Within a group, UE 10 has an independent device association ID. This device association ID is an ID that uniquely identifies this AIoT device 40 within that group.

[0075] In step 400, the reader sends a paging message to multiple AIoT devices, wherein the paging message includes a mapping table of multiple device association identification IDs and multiple random access IDs. The mapping table records the mapping relationship between the multiple device association IDs and the multiple random access IDs, and the random access IDs indicate the order in which the corresponding device IDs access the reader in different time slots.

[0076] In step 402, multiple AIoT devices 40 are accessed in the order indicated by the random access ID according to the paging message.

[0077] Regarding the device association ID, this embodiment provides the following solution:

[0078] Option 1: Add a mapping list of multiple group local device IDs and multiple random access IDs to the paging message. Each group local device ID corresponds to one of the random access IDs, meaning that the reader assigns a random access ID to each AIoT device 40. Therefore, multiple AIoT devices 40 will sequentially select time slots to access the network based on the random access IDs assigned by the reader.

[0079] Option 2: Include a mapping list of AIoT device IDs and random access IDs in the paging message. The device ID of the AIoT device 40 can be its complete ID or a short ID. The device ID and random access ID correspond to each other, meaning that the reader assigns a random access ID to each AIoT device 40. Therefore, multiple AIoT devices 40 will sequentially select time slots to access the network based on the random access IDs assigned by the reader.

[0080] Option 3: Add a mapping list of local device IDs and random access IDs to the paging message. The local device ID is a unique device ID for this reader. The mapping list of local device IDs and random access IDs corresponds to each AIoT device 40, meaning the reader assigns a random access ID to each device. Therefore, multiple AIoT devices 40 will sequentially select time slots to access the network based on the random access IDs assigned by the reader.

[0081] According to the technical solution of Embodiment 2, when the reader sends a paging message to multiple AIoT devices, the paging message includes a mapping table of multiple device association identification IDs and multiple random access IDs. The mapping table records the mapping relationship between the multiple device association IDs and the multiple random access IDs. The random access IDs indicate the order in which the corresponding device ID accesses the reader in different time slots. Therefore, a single paging process can allocate multiple AIoT devices to access the reader in different time slots, allowing multiple AIoT devices to access the reader without conflict. This avoids repeated paging and re-access, and has the beneficial effect of reducing additional signaling overhead.

[0082] Example 3

[0083] Referring to Figure 1, a paging area can be covered by one or more UEs 10. When the core network 130 sends a paging message to the base station 200, the base station 200 sends a paging message to the UE 10. However, since the area covered by the base station 200 includes Area 1 and Area 2, Area 1 includes the control range of UE1 and UE2, while Area 2 only includes the control range of UE3, it is necessary to specify which area needs to be paging. If the core network device 300 only wants to paging Area 1, it needs to notify UE1 and UE2 to paging, but not UE3. This is where the concept of a paging area ID comes in. When the core network device 300 performs paging, it only paging the required paging area.

[0084] If AIoT device 40 moves from the control range of UE1 to the control range of UE2, and AIoT device 40 previously received a paging message from UE1, but now AIoT device 40 receives a paging message from UE2, but since UE1 / UE2 belong to the same paging area, AIoT device 40 does not need to perform a paging area update process.

[0085] Please refer to Figure 5, which illustrates the operation of updating the paging area through AIoT device 40, reader, base station, and core network equipment at various stages according to an embodiment of the present invention. The operation of updating the paging area through AIoT device 40, reader, base station, and core network equipment at each stage includes operations 501-505.

[0086] Operation 501: A paging message is sent by the reader to an AIoT device, wherein the paging message includes at least one of the following: reader ID, UE ID, paging area ID, paging update indicator, or device indicator All_devices_Indicator.

[0087] Because the TA / cell ID representing the location was originally sent in the SIB system message, but now there is no SIB, in order to update the UE 10 location, the reader ID / UE ID / paging area ID can only be sent in the paging message.

[0088] A paging update indicator is added to the paging message. If a paging update indicator is received, AIoT device 40 will update the paging area after random access. This paging update indicator parameter ensures that only AIoT devices 40 whose paging areas have changed will initiate a paging area update; other AIoT devices 40 whose paging areas have not changed do not need to initiate a paging area update.

[0089] The device indicator is used to instruct all AIoT devices 40 to access the network and update their location information after receiving a paging message.

[0090] Operation 502: Determine whether the original paging area ID / reader ID of AIoT device 40 has changed. If the paging area ID / reader ID has changed, AIoT device 40 will initiate a paging area ID update process.

[0091] Operation 503: AIoT device 40 receives an instruction from the paging message that the paging area needs to be updated.

[0092] Operation 504: The reader sends an update paging area ID (AIoT device ID, paging area ID) message to base station 200. Because a reader can have multiple paging area IDs, the paging area ID is carried in the paging area ID message to distinguish which paging area ID the reader needs. If a reader has only one paging area ID, then the paging area ID message does not need to include the paging area ID.

[0093] Operation 505: Base station 200 sends an update paging area message to core network device 300. The update paging area message includes the AIoT device ID and the paging area ID. The reason for carrying the paging area ID in the update paging area message is that core network device 300 needs to know which paging area ID the AIoT device 40 belongs to.

[0094] It is worth noting that the above steps can be performed sequentially or not sequentially. In addition, only some steps can be performed instead of all steps each time.

[0095] Through the technical solution of Embodiment 3 of the present invention, when the AIoT device 40 moves and causes a change in the paging area, the AIoT device 40 can notify and update the paging area in real time. Therefore, the paging area corresponding to the AIoT device 40 can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0096] Example 4

[0097] As shown in Figure 1, each UE 10, acting as an intermediary node, has its own control area. Therefore, when a new UE enters the control area, it should proactively update its paging area ID with the base station 200. Since UE 10 is mobile, its paging area will change when it moves from paging area 1 to paging area 2. At this time, UE 10 needs to change its paging area. Therefore, this invention provides embodiments for UE 10 initiating the update of its paging area ID and embodiments for base station 200 or core network equipment 30 initiating the update of its paging area ID.

[0098] Please refer to Figure 6, which illustrates the operation of updating the paging area ID initiated by UE 10 at various stages according to an embodiment of the present invention. The operation of UE 10, base station, and core network equipment updating the paging area ID at each stage includes operations 601-605.

[0099] In operation 601, base station 200 provides paging area ID configuration to UE 10. The paging area ID configuration can be a mapping relationship between location information broadcast in the SIB message, such as the synchronization signal block SSB index SSB_index and the paging area ID (e.g., a paging area ID table). UE 10 can then determine its location information and, through the paging area ID table, identify which paging area ID it belongs to.

[0100] In operation 602, UE 10 sends a paging area ID update request to base station 200. The paging area ID update request includes UE ID / reader ID, new paging area ID, location information, etc. The location information includes at least one of the following: GNSS address and SSB index, etc. The identifier of UE 10 can be either the UE ID or the reader ID used by UE 10 as a reader.

[0101] In operation 603, base station 200 forwards the update paging area request message to core network equipment 30.

[0102] In operation 604, core network device 30 sends an updated paging area response to UE 10. The updated paging area response includes the UE ID / reader ID and a new paging area ID. The updated paging area response provides a usable paging area ID.

[0103] In operation 605, base station 200 sends the new paging area ID assigned by core network equipment 30 to UE 10.

[0104] Please refer to Figure 7, which illustrates the operation of updating the paging area ID initiated by base station 200 or core network device 30 at various stages according to an embodiment of the present invention. When a configuration change of base station 200 or core network device 30 causes a change in the paging area ID, the operation of UE 10, base station, and core network device updating the paging area ID at each stage includes operation 701-operation 702.

[0105] In operation 701, core network equipment 30 sends an update paging area ID request to base station 200. The update paging area ID request includes at least one of the following: UE ID / reader ID and UE 10's new paging area ID.

[0106] In operation 702, after receiving the update paging area ID request from the core network device 30, the base station 200 sends an update paging area ID request to the UE 10. At this time, the update paging area ID request sent by the base station 200 includes the new paging area ID of the UE 10.

[0107] This invention provides embodiments for updating the paging area ID initiated by UE 10 and by base station 200 or core network device 30. When the paging area ID changes, UE 10, base station 200, and core network device 30 can update the paging area ID in real time. Therefore, the paging area ID corresponding to AIoT device 40 can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0108] Example 5

[0109] In addition to using the paging area ID to page UE 10 as mentioned in the above embodiments, this invention also proposes using the association between reader ID and AIoT device ID to page UE 10. When the reader ID and AIoT device ID are bound, the core network device 30 can find out which reader can find the AIoT device ID when paging.

[0110] Please refer to Figure 8, which illustrates the operation of the present invention in various stages, whereby the reader updates the association between the reader ID and the AIoT device ID to the core network device 30. The AIoT device, reader, base station, and core network device are involved in operations 801-803 at each stage.

[0111] Once AIoT device 40 connects to the reader, the reader can save the association between the AIoT device ID and the reader ID. The reader then sends the association between the AIoT device ID and the reader ID to base station 200, which in turn sends it to core network device 30.

[0112] In operation 801, when AIoT device 40 completes an access process with the reader, the reader obtains the AIoT device ID of AIoT device 40 during the access process.

[0113] During operation 802, the reader transmits a first location report to the base station 200, reporting the location information of this AIoT device ID. This first location report includes the AIoT device ID.

[0114] In operation 803, base station 200 reports a second location report to core network equipment 30, which includes reader ID / UE ID and AIoT device ID. Core network equipment 30 then obtains the mapping relationship between reader ID / UE ID and AIoT device ID.

[0115] It is worth noting that the above operations can be performed sequentially or not sequentially. In addition, only some operations can be performed instead of all operations each time.

[0116] Please refer to Figure 9, which illustrates the operation of the core network device 30 in each stage of the present invention, whereby the AIoT device 40 is located using the reader ID in the paging message. The AIoT device, reader, base station, and core network device operate in stages 901-903. The function of this embodiment is to allow the core network device 30 to maintain the mapping relationship between the reader ID and the AIoT device ID, and then add this mapping to the paging message, thereby informing the base station 200 which reader to send the AIoT device ID to.

[0117] In operation 901, the core network device 30 stores the mapping relationship between the reader ID and the AIoT device ID. Therefore, when it is necessary to page a certain AIoT device 40, because the paging message includes the reader ID, the base station 200 can use the reader ID in the paging message to specify the reader to send a page to this AIoT device 40.

[0118] During operation 902, base station 200 sends a paging message to the reader, which includes the AIoT device ID.

[0119] In operation 903, the paging message from the reader to the AIoT device 40 includes the reader ID. The AIoT device 40 checks whether the received reader ID is the same as the previously received reader ID. If the received reader ID is different from the previously received reader ID, the AIoT device 40 updates the reader ID.

[0120] It is worth noting that the above steps can be performed sequentially or not sequentially. In addition, only some steps can be performed instead of all steps each time.

[0121] The embodiment shown in Figure 8 updates the association between the reader ID and the AIoT device ID to the core network device 30, while the embodiment shown in Figure 9 uses the reader ID in the paging message to locate the AIoT device 40. Because the reader ID and the AIoT device ID are associated and the core network device 30 stores the mapping relationship between the reader ID and the AIoT device ID, the paging message sent by the core network device 30 to the base station 200 can include the reader ID. This allows the base station 200 to efficiently determine which reader sent the AIoT device ID through the reader ID in the paging message, thus improving paging efficiency.

[0122] Compared to existing technologies, the technical solution of one embodiment of the present invention enables a reduction in additional signaling overhead when a base station or user equipment is connected to multiple environmental devices as a reader. If a single paging does not successfully connect all AIoT devices to the base station 200 or user equipment, the successfully connected UEs will not reconnect during repeated paging.

[0123] According to another embodiment of the present invention, when a reader sends a paging message to multiple AIoT devices, the paging message includes a mapping table of multiple device association identification IDs and multiple random access IDs. The mapping table records the mapping relationship between the multiple device association IDs and the multiple random access IDs. The random access IDs indicate the order in which the corresponding device IDs access the reader in different time slots. Therefore, a single paging process can allocate multiple AIoT devices to access the reader in different time slots, allowing multiple AIoT devices to access the reader without conflict. This avoids repeated paging and re-access, and has the beneficial effect of reducing additional signaling overhead.

[0124] According to another embodiment of the present invention, when the paging area changes due to the movement of the AIoT device, the AIoT device can notify and update the paging area in real time. Therefore, the paging area corresponding to the AIoT device can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0125] Through another embodiment of the technical solution of the present invention, through embodiments of updating the paging area ID initiated by the UE and embodiments of updating the paging area ID initiated by the base station or core network equipment, when the paging area ID changes, the UE, base station, and core network equipment 30 can update the paging area ID in real time. Therefore, the paging area ID corresponding to the AIoT device 40 can be updated in real time, which has the beneficial effect of maintaining the paging area in real time and thus improving paging efficiency.

[0126] In another embodiment of the present invention, the reader updates the association between the reader ID and the AIoT device ID to the core network device, and the core network device uses the reader ID to find the AIoT device in the paging message. Because the reader ID and the AIoT device ID are associated and the core network device stores the mapping relationship between the reader ID and the AIoT device ID, the paging message sent by the core network device to the base station can include the reader ID. This allows the base station 200 to efficiently determine which reader sent the AIoT device ID through the reader ID in the paging message, thus improving paging efficiency.

[0127] According to an example embodiment, a chip is provided, the chip including: a processor for calling and running a computer program from a memory, causing a device on which the chip is installed to perform the method according to any one of the above embodiments, examples, or example embodiments.

[0128] According to an example embodiment, a computer-readable storage medium is provided for storing a computer program that causes a computer to perform a method according to any one of the above embodiments, examples, or example embodiments.
