[0001] This application claims priority to U.S. Provisional Application No. 63 / 747,830, entitled “APPARATUS AND METHOD FOR ENABLING DISABLED AMBIENT IOT DEVICE USING PAGING ID,” filed on January 21, 2025, which is hereby incorporated in its entirety by this reference.TECHNICAL FIELD

[0002] The present disclosure relates to the field of communication systems, and more particularly, to a method for managing an ambient Intemet-of-Things (A-IoT) device in a wireless communication system and a related apparatus.BACKGROUND

[0003] In fifth-generation (5G) mobile communication systems, ambient Intemet-of-Things (A-IoT) service is envisioned to support massive low-power devices deployed for applications such as automated warehousing, inventory tracking, smart grid, industrial manufacturing, and home automation. A-IoT devices may operate over both licensed and unlicensed spectrum and typically transmit small amounts of sensed data to a 3rd generation partnership project (3GPP) network or an application server only when triggered. Because the number of the devices can reach millions, uncontrolled or simultaneous uplink transmissions could overload radio resources and degrade network performance. Therefore, it is desirable for a network to manage when an A-IoT device is permitted to transmit or to temporarily disable its radio -frequency (RF) transmission capability during congestion or maintenance periods. However, conventional techniques, such as back-off timers or “remote kill switch” functions used for user equipment (UE), are not suitable for battery-less, energy-harvesting A-IoT devices that cannot maintain timers or internal states. In particular, the existing 3GPP inventory-and-command procedure fails to re-enable a temporarily disabled A-IoT device, since a disabled device cannot transmit the required response message to complete the procedure.

[0004] Therefore, there is a need for a method for managing an ambient Intemet-of-Things (A-IoT) device in a wireless communication system and a related apparatus.SUMMARY

Specifically, the terminologies in the embodiments of the present disclosure are merely for describing the purpose of the certain embodiment, but not to limit the disclosure.

[0031] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS), a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a future 5th generation (5G) system (may also be called a new radio (NR) system), an evolution system of a NR system, a LTE-based access to unlicensed spectrum (LTE-U) system, a NR-based access to unlicensed spectrum (NR-U) system, an universal mobile telecommunication system (UMTS), a global interoperability for microwave accessAtty. Dkt. No. 10085-01-0193-PCT (WiMAX) communication system, wireless local area networks (WLAN), wireless fidelity (Wi-Fi), or other communication systems, etc.

[0032] Optionally, a user equipment (UE) mentioned in the embodiments of the present application may refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal may be a cellular radio telephone, a cordless telephone, a session initiation protocol (SIP) telephone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication functions, a computing device, other processing devices coupled with a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, a terminal device in a future evolved public land mobile network (PLMN), etc.

[0033] Optionally, the communication system in the embodiment of the present application may be applied to an unlicensed spectrum, where the unlicensed spectrum may also be considered as a shared spectrum, or the communication system in the embodiment of the present application may also be applied to a licensed spectrum, where the licensed spectrum can also be considered an unshared spectrum.

[0034] 5G ambient loT (A-IoT) service is a new 5G service that may be used to support various use cases such as, automated warehousing, inventory management, smart grid, non-public logistics, industrial manufacturing, loT sensors, and smart home. A-IoT devices operate in both licensed and unlicensed spectrum. A-IoT devices collect information related to the use case and report back to the 3GPP network or application server via a 3GPP network when requested. The 5G A-IoT service enables massive low-power devices operating over licensed and unlicensed spectrum to collect and report use-case-specific information to a 3 GPP network or application server on demand.

[0035] It is beneficial in terms of network performance and network reliability that A-IoT device only communicates when requested. Otherwise, the vast number of A-IoT devices (expected to be numbered in the millions) communicating or sending information to the network at the same time may overwhelm the network’s bandwidth and cause undesirable side effects such as denying access to other devices such as UEs trying to gain access to the network. It is advantageous for network performance and reliability to allow A-IoT devices to communicate only when requested, thereby preventing network congestion and access denial caused by simultaneous transmissions from massive numbers of devices.

[0036] It is beneficial for the 5G network to be able to control when A-IoT devices may communicate and when they cannot communicate, e.g., disable RF transmission capability of an A-IoT device. Once an A-IoT device is temporarily disabled, the 5G network has to be able to re-enable the A-IoT device when network conditions allow such, without having to reset (e.g., re-configure or re-provision the device) the device manually. It is desirable for the 5 G network to control A-IoT device communication by temporarily disabling or re-enabling their RF transmission capability as needed, without requiring manual device reset or re-provisioning.

[0037] A number of UE vendors offer solutions for “remote kill switch” or “remote wipe” that may be used to wipe clean a stolen UE. Current 3 GPP standards also support features such as backoff timer that is used when a UE stops requesting network access temporarily until a certain amount of time has passed. Existing UE solutions such as “remote kill switch” and 3 GPP -defined backoff timers allow temporary suspension or erasure of device access, providing limited control over network communication behavior.Atty. Dkt. No. 10085-01-0193-PCT

[0038] In order to re-enable a temporarily disabled A-IoT device, an enabling mechanism for re-enabling a temporarily disabled A-IoT device is being considered. Once a device has been permanently disabled remotely (e.g., shut down) using techniques such as “remote kill switch” or “remote wipe”, the device may no longer be able to be reenabled without having to go through manual reconfiguration or manual provisioning. An enabling mechanism is needed to remotely re-activate a temporarily disabled A-IoT device, since permanently disabled devices using “remote kill switch” or “remote wipe” cannot be restored without manual reconfiguration or provisioning.

[0039] In the case of temporarily disabling of an A-IoT device, it may be to stop the A-IoT device from transmitting to the network temporarily until a time when the network is available (e.g., less congested). Using a backoff timer to enable an A-IoT device has the disadvantage that the A-IoT device keeps a timer or a counter active which requires the A-IoT device to maintain a state which goes against the characteristics of the A-IoT device (e.g., A-IoT devices are characterized by not having a conventional battery (or with limited battery) and is powered by energy harvesting, limited storage, and limited computing capabilities.) Temporarily disabling an A-IoT device can help reduce network congestion, but using a backoff timer is inefficient since it requires state maintenance inconsistent with the low-power, battery less nature of A-IoT devices.

[0040] FIG. 1 illustrates an exemplary inventory and command procedure in Ambient Internet of Things (A-loT) communication system according to an embodiment of the present disclosure. The current solution considered in 3GPP using inventory and command procedure as illustrated in FIG. 1 may not work. The inventory and command procedure requires the A-IoT device to respond after the initial inventory request message (e.g., A-IoT paging message) before responding to enabling command in the command request message. However, when the A-IoT device has been temporarily disabled (e.g., A-IoT device may only receive RF transmission and cannot send RF transmission), the A-IoT device may not be able to complete the inventory request by transmitting a response due to the fact that the RF transmission capability has been temporarily disabled. Since the network may not receive a response from the A-IoT device for the inventory request (e.g., paging), the network may terminate the inventory and command procedure and therefore the A-IoT device may not be able to be re-enabled. The existing 3 GPP inventory and command procedure fails to re-enable a temporarily disabled A-IoT device because such a device cannot transmit the required response message, causing the network to terminate the procedure and preventing successful reactivation.

[0041] Some embodiments of the present disclosure provide a mechanism for managing or permanently disabling an A-IoT device whose RF transmission capability has been temporarily disabled.

In some embodiments, all A-IoT devices belonging to a same group are assigned a same group paging ID.

[0051] FIG. 6 illustrates a method 600 for managing an ambient Intemet-of-Things (A-IoT) device, performed by a reader in a wireless communication system according to an embodiment of the present disclosure. The method 600 performed by the reader is configured to implement some embodiments of the disclosure. Some embodiments of the disclosure may be implemented into the method 600 performed by the reader using any suitably configured hardware and / or software. In some embodiments, the method 600 performed by the reader includes: an operation 602, transmitting, to the A-IoT device, an A-IoT paging message, wherein the A-IoT paging massage includes a first paging identifier (ID) set to a correction paging ID assigned to the A-IoT device, and an abnormal operational state of the A-IoT device is corrected when the first paging ID matches a stored correction paging ID of the A-IoT device. This can solve issues in the prior art and other issues. Further, the proposed some embodiments can efficiently correct an abnormal operational state of the A-IoT device without protocol modification, reduce operational complexity, and / or improve overall network reliability.

[0052] In some embodiments, the method further includes receiving, from the A-IoT device, a device-to-reader (D2R) data transmission in response to the A-IoT paging message. In some embodiments, the A-IoT paging message further includes at least one paging ID including at least one of the following: a paging ID for an inventory procedure, a paging ID for an inventory and command procedure, a paging ID for group operations, or the correction paging ID that is valid when an RF transmission capability of the A-IoT device is temporarily adjusted. In some embodiments, all A-IoT devices belonging to a same group are assigned a same group paging ID. In some embodiments, the reader is configured to transmit the same group paging ID to activate all A-IoT devices belonging to the same group. In some embodiments, the reader transmits a group paging ID shared by multiple A-IoT devices to trigger device-to-reader communication, enabling activation of individual or grouped devices using predefined paging IDs for various procedures without altering existing protocols.

[0053] In some embodiments, the A-IoT paging message includes a second paging ID set to a permanent disable paging ID assigned to the A-IoT device.

In some embodiments, the method further includes receiving, from the A-IoT device, a D2R data message confirming that a permanent adjusting of the A-IoT device has been completed. In some embodiments, the reader is configured to transmit the A-IoT paging message according to an inventory-only procedure or an inventory-and-command procedure. In some embodiments, the A-IoT paging message includes a permanent disable paging ID that, when matched with the stored ID of an A-IoT device, causes the device to permanently disable its RF transmission capability and send a D2R confirmation message, with the reader transmitting the paging message using either an inventory-only or inventory-and-command procedure.

[0054] Examples:

[0055] FIG. 7 illustrates an exemplary inventory-only procedure in an A-IoT communication system according to an embodiment of the present disclosure. FIG. 7 illustrates that, the proposed solution reuses the inventory only procedure presently defined in 3GPP TR 38.769 as is. However, the novelty resides in the design of the paging ID. A-IoT device may only respond to paging ID in the A-IoT paging message that matches the paging ID stored in the A-IoT device. The A-IoT device is enhanced to store and respond to multiple paging IDs for different purposes, for example, a paging ID for ordinary inventory procedure or inventory and command procedure, a paging ID for group operations (same group paging ID is assigned to all members of the sameAtty. Dkt. No. 10085-01-0193-PCT group), and paging ID (e.g., correction paging ID or permanent disable paging ID) that is only valid when the A-IoT device’s RF transmission capability is temporarily adjusted. In some embodiments, the proposed solution reuses the existing 3GPP TR 38.769 inventory-only procedure but introduces a novel paging ID design, enabling A-IoT devices to store and respond to multiple paging IDs for different purposes such as inventory, group operations, and enabling or permanently disabling RF transmission.

[0056] When the A-IoT device has the correction paging ID stored and the RF transmission capability of the A-IoT device temporarily disabled, the A-IoT device is only able to respond to the A-IoT paging message with the paging ID that matches the correction paging ID stored in the A-IoT device. When an A-IoT device’s RF transmission capability is temporarily adjusted, it can only respond to an A-IoT paging message containing a paging ID that matches its stored correction paging ID.

[0057] In the current specifications, when the A-IoT device’s RF transmission capability has been temporarily disabled, instruction to re-enable (or for other instructions such as READ, WRITE, etc.) may only be issued using the COMMAND part of the inventory and command procedure. Since the A-IoT device may actively receive RF transmission from the A-IoT paging message but not be able to transmit a reply in (FIG. 1, Step B’s D2R data transmission message, the network not receiving a A-IoT paging response from the A-IoT device may treat the A-IoT paging message as failed and not continue with the Step C in FIG. 1 (e.g., the command procedure portion of the inventory and command procedure). In current 3 GPP specifications, re-enabling a temporarily disabled A-IoT device requires a command phase in the inventory and command procedure; however, since such a device cannot transmit a response, the network treats the paging as failed and does not proceed with the command step, preventing successful reactivation.

[0058] FIG. 8 illustrates an exemplary inventory-only procedure with paging ID set to an A-IoT device correction paging ID in an A-IoT communication system according to an embodiment of the present disclosure. FIG. 8 illustrates that, in the new mechanism, instruction to enable (e.g., the correction paging ID in place of a traditional paging ID in the A-IoT paging message) the temporarily disabled A-IoT device is the special paging ID itself as illustrated in FIG. 8. The A-IoT device is enhanced to respond to one or more paging IDs, for example, a paging ID for ordinary inventory procedure or inventory and command procedure, a paging ID for group operations (same group paging ID is assigned to all members of the same group), and paging ID (e.g., correction paging ID or permanent disable paging ID) that is only valid when the A-IoT device’s RF transmission capability is temporarily adjusted. In the case when the A-IoT device’s RF transmission capability is temporarily adjusted, the only A-IoT paging message the A-IoT device may respond to is the A-IoT paging message with the paging ID set to the correction paging ID (or to the permanent disable paging ID) stored by the A-IoT device. In some embodiments, the proposed mechanism uses a special correction paging ID within the A-IoT paging message to directly re-enable a temporarily disabled device, allowing the A-IoT device to respond only to paging messages carrying its stored enable or permanent disable paging ID.

[0059] FIG. 9 illustrates an exemplary inventory procedure with paging ID set to an A-IoT device permanent disable paging ID in an A-IoT communication system according to an embodiment of the present disclosure. FIG. 9 illustrates that, since A-IoT device is provisioned with a correction paging ID (among other paging IDs), when the A-IoT paging message (e.g., inventory request) with the correction paging ID as the paging ID, the A-loT device verifies that the paging ID in the A-IoT paging message against the correction paging ID stored inAtty. Dkt. No. 10085-01-0193-PCT the A-IoT device. In some embodiments, when an A-IoT paging message containing a correction paging ID is received, the A-IoT device verifies the paging ID against its stored correction paging ID to determine whether to respond or take the corresponding action. If the paging ID in the A-IoT paging message and the stored correction paging ID are a match, the A-IoT device to is able to respond and therefore enable the temporarily disabled RF transmission capability without having to wait for Step C in FIG. 1 (e.g., the command procedure). Furthermore, normal inventory procedure may follow without changes to the protocol, procedure and air interface. After re-enabling the temporarily disabled RF transmission capability, the A-IoT device responds to the A-IoT paging message by replying in Step B’s D2R data transmission message. If the correction paging ID in the A-IoT paging message matches the stored ID, the device immediately re-enables its temporarily disabled RF transmission capability, replies with a D2R message, and continues the normal inventory procedure without any protocol or interface modification.

[0060] In yet another embodiment, the paging ID in the A-IoT paging message is set to another type of paging ID (e.g., permanent disable paging ID) as illustrated in FIG. 9. A permanent disable paging ID used by the A-loT device whose RF transmission capability has been temporarily disabled to permanently disable the RF transmission capabilities of an A-IoT device. In the case, the A-IoT paging message contains a paging ID that is set to the value of the A-IoT’s permanent disable paging ID. When the A-IoT device receives the A-IoT paging message with the paging ID that matches the permanent disable paging ID in the A-IoT device, the A-IoT device is able to complete the request by permanently disable the temporarily disabled RF transmission capability without having to wait for Step C in FIG. 1 (e.g., the command procedure). The A-IoT device may also reply to the A-IoT paging message with a D2R data transmission to confirm to the network that the permanent adjusting has been carried out. In some embodiments, when an A-IoT paging message includes a permanent disable paging ID matching the device’s stored ID, the A-IoT device permanently adjusts its RF transmission capability without executing the command procedure and may send a D2R confirmation message to the network.

[0061] FIG. 10 illustrates an exemplary paging with correction paging ID in inventory and command procedure in an A-IoT communication system according to an embodiment of the present disclosure. FIG. 10 illustrates that, in another embodiment, the proposed solution also works for the case of enabling an A-IoT device with RF transmission capability temporarily disabled when the inventory and command procedure is used instead of the inventory only procedure as the inventory and command procedure is considered as an extension to the inventory only procedure. In some embodiments, the proposed mechanism also applies to the inventory and command procedure, enabling an A-IoT device with temporarily disabled RF transmission capability, as this procedure extends the existing inventory-only procedure.

[0062] In some embodiments, mechanism that enables the RF transmission capability of an A-IoT device that has been temporarily disabled provide at least one benefit to both at least one A-IoT device and the overall A-loT communication system. Some embodiments of the present disclosure reuse the existing inventory-only procedure or inventory and command procedure without any modification to the messaging and protocol. This allows the enabling or permanent adjusting of an A-IoT device whose RF transmission capability is temporarily adjusted. Reusing existing protocols makes any changes only limited to the A-IoT device. In some embodiments, the proposed mechanism reuses existing inventory-only or inventory-and-command procedures without protocol modification, enabling or permanently disabling A-IoT devices with temporarily disabled RF transmission capability while limiting changes to the device side.Atty. Dkt. No. 10085-01-0193-PCT

[0063] Some embodiments of the present disclosure allow an A-IoT device whose RF transmission capability that has been temporarily disabled to be enabled without having the device to go through a provisioning process to return to normal operation. Provisioning of potentially many A-IoT devices in the operator’s network is not only costly, but very inefficient, especially when the possible reason for temporarily disabling the RF transmission capability of the A-IoT device is due to network congestion. In some embodiments, the proposed mechanism enables a temporarily disabled A-IoT device to resume normal operation without requiring reprovisioning, thereby reducing operational cost and improving efficiency, particularly when RF transmission is disabled due to network congestion.

[0064] RF transmission capability of a A-IoT device for example when the A-IoT devices’ service life has reached an end or when the network deems that the devices may be experience technical difficulties or may be misbehaving, for example if the devices are being attacked (e.g., hijacked by attackers) to perform illegitimate activities. In case of the RF transmission capability of the A-IoT device has been temporarily disabled, it may still be useful for the operator to permanently disable the RF transmission capability of the A-IoT device when the operator deems the device no longer useful or for other reasons such as enabling the device would not resolve the issue that causes the device to be temporarily disabled in the first place. Permanently disabling the RF transmission capability of an A-IoT device helps the operator to remove the impacted devices out of its network to improve network performance. In some embodiments, the proposed mechanism enables a temporarily disabled A-IoT device to resume normal operation without requiring re-provisioning, thereby reducing operational cost and improving efficiency, particularly when RF transmission is disabled due to network congestion.

[0065] Alternative to using the mechanisms is for the network to modify the inventory and command procedure in FIG. 1 such that the A-IoT paging message in Step A is sent immediately followed by Cl R2D data transmission message, even without A-IoT device responding the A-IoT paging message. Alternatively, the network may modify the inventory and command procedure to send the command message immediately after the A-IoT paging message, without waiting for a response from the A-IoT device. The A-IoT device would have to understand that if A-IoT paging is followed immediately by Cl R2D Data transmission and that it is intended to be used to enabled its temporarily disabled RF transmission capability. This requires a logic change in the inventory and command procedure in the A-IoT system and a change in how the A-IoT device processes the A-loT paging and Cl R2D data transmission message. The A-IoT device would need new logic to recognize that an immediate Cl R2D data transmission following an A-IoT paging message is intended to re-enable its temporarily disabled RF transmission capability, requiring modifications to both the procedure and device processing.

[0066] Another alternative is to modify A-IoT paging message to include an enable command or a permanent disable command. Paging message may not be able to carry additional parameter due to message size restrictions. Other alternative is to do a manual reset, but this is this has enormous efficiency impact and may not be practical if the number of A-IoT devices are huge or are deployed in a large area. Another alternative is to embed enable or permanent disable commands within the A-IoT paging message, but message size limits or the impracticably of manual resets for large-scale deployments make such approaches inefficient.Atty. Dkt. No. 10085-01-0193-PCT

[0067] In an embodiment for permanently disabling the device’s RF transmission capability, an alternative approach is to perform a permanent “kill,” rendering the device completely inoperable.

[0068] In summary, some embodiments of the present disclosure propose a mechanism that reuses existing 3GPP TR 38.769 inventory -only and inventory-and-command procedures without any protocol modification to enable or permanently disable an A-IoT device whose RF transmission capability has been temporarily disabled. The technical feature lies in the introduction of special paging IDs, such as correction paging ID and permanent disable paging ID, which allow A-IoT devices to selectively respond to specific paging messages even when their RF transmission is disabled. This mechanism enables efficient remote reactivation or permanent deactivation without requiring re-provisioning or manual intervention, reducing operational costs and improving network performance. Furthermore, it supports large-scale deployments by minimizing network-side changes and maintaining compatibility with existing signaling frameworks. Alternative approaches, such as modifying procedures, embedding commands in paging messages, or performing manual resets, are less efficient or impractical, especially for massive A-IoT deployments.
