Processing method of a reader-writer and communication device

[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 202411386493.7, filed on September 30, 2024, and Chinese Patent Application No. 202411425517.5, filed on October 12, 2024, in China, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and specifically relates to a processing method of a reader-writer and a communication device. BACKGROUND

[0004] To meet the intelligent needs of the Internet of Things, the Ambient Internet of Things (AIoT), also known as Ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an Internet of Things (IoT) service. A terminal such as an AIoT device is a low-power IoT device, and the overall power consumption of such devices is low, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc. AIoT devices can also be described as passive IoT devices or responding devices.

[0005] In related technologies, a network function (NF) entity such as an Ambient IoT Function (AIoTF) can obtain terminals (User Equipment, UE) in a specified area by subscribing to the UEs-In-Area-Report event of an Access and Mobility Management Function (AMF).

[0006] When the specified area is large, the AMF returns all UEs in the specified area to the AIoTF, and the AIoTF still needs to filter out the UE reader-writers among them. This approach can result in a significant waste of interaction resources.

[0007] On the other hand, due to the mobility of the reader, the selected reader or the designated target reader can move out of the designated area of the AIoT related service, resulting in the AIoT related service being unable to be executed by the selected reader or the designated target reader.

[0008] In addition, the selection of the reader based on the area of the AIoT related service designated by the application function (AF) and the service range of the reader also has a problem that the service range of the reader is difficult to define, such as being limited by the power change of the reader, shielding, etc., and it is difficult to map to the area in the communication such as the tracking area (TA), the cell level area, and there is a possibility that the network cannot recognize, and thus the appropriate reader cannot be accurately selected.

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0053] The core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), etc. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited. If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0054] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices together, and the embodiments of the present application do not make a specific limitation. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a special hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0055] The selection method of the UE reader or the intermediate node in the AIoT mainly includes the following ways:

[0056] Way 1: An application function (AF) carries an identity (ID) of a UE reader in an AIoT service related request (such as an inventory request or a command request) to an AIoT F / access and mobility management function (AMF), and the AIoT F / AMF selects the UE reader according to the UE reader ID. The ID of the UE reader can be a subscription permanent identifier (SUPI) of the UE and a generic public subscription identifier (GPSI).

[0057] Way 2: The AF carries a target area in an AIoT service related request (such as an inventory request or a command request) to the AIoT F / AMF, and the AIoT F / AMF selects the UE reader according to the target area. However, the UE reader provides its own AIoT related service area in the registration stage, and the AIoT F / AMF determines the UE reader according to the target area and the service area of the UE reader.

[0058] Way 3: The AF carries a target device ID in an AIoT service related request (such as an inventory request or a command request) to the AIoT F / AMF, and the target device ID is associated in the network and is served by the UE reader of the device, so that the AIoT F / AMF selects the UE reader.

[0059] Method 4: AF carries target device ID in AIoT service related request (such as inventory request, command request), and also provides the UE associated with the target device to AIoTF / AMF (note that the associated UE here is not UE reader). AIoTF / AMF takes the location of the associated UE as the location of the target device, and selects the UE reader near the location according to the location.

[0060] Method 5: AF carries target device ID in AIoT service related request (such as inventory request, command request) to AIoTF / AMF. If AIoTF / AMF can find an associated UE in 5GC, AIoTF / AMF takes the location of the associated UE as the location of the target device, and selects the UE reader near the location according to the location. But the premise here is that the associated UE provides its associated device ID to 5GC in advance, such as when it registers.

[0061] When AIoTF / AMF selects UE reader, it can also consider other factors, such as the AIoT capabilities of UE reader, such as supported spectrum, power saving mode, authorization information, such as whether UE reader allows inventory of target device, etc. There are also factors such as selection of UE reader by RAN, when RAN can also consider interference, spectrum, etc. as selection factors of UE reader.

[0062] Consumer (consumer) network function (Network Function, NF) can subscribe to some related events from AF, reflecting the situation of UE in the target area.

[0063] Presence-In-AOI-Report event is used for consumer NF to subscribe to the presence of a specific UE, a group of UEs or any UE in the target area to AMF. AMF determines whether the UE is in the target area, or outside the target area, or does not know the information according to the location of the UE. In the later stage, AMF can also report to consumer NF the presence of UE in the target area after the UE moves according to the movement of UE. Consumer NF can also subscribe to UEs-In-Area-Report event from AMF to obtain the number of UEs in a specific area or the UE ID in a specific area.

[0064] In the present application, the subscription of an event or the event subscription can also be referred to as the subscription of an event or the event subscription.

[0065] In an optional embodiment of the present application, the terminal device comprises one or more terminal devices. In an optional embodiment of the present application, the AIoT function can also be referred to as a function of management and / or control of the operation of a terminal device (such as an AIoT device).

[0067] 2) determine whether to authorize the customer's AIoT operation request;

[0068] 3) distribute AIoT operations to readers or devices in direct communication with terminal devices (directly sent or forwarded through other network elements);

[0069] 4) receive AIoT operation execution results;

[0070] 5) summarize AIoT operation execution results;

[0071] 6) send AIoT operation results to customers.

[0072] 7) responsible for the management and control of AIoT operations (which can also be referred to as one of the following: AIoT task, AIoT process);

[0073] 8) authorize corresponding AIoT operations according to customer AIoT operation requests;

[0074] 9) distribute AIoT operations to a second AIoT function (directly sent or forwarded through other network elements);

[0075] 10) receive AIoT operation task execution results;

[0076] 11) summarize AIoT operation task execution results;

[0077] 12) send AIoT task execution results to customers.

[0078] In an optional embodiment of the present application, the AIoT function can also be referred to as an AIoT management and / or control network function. The AIoT function includes but is not limited to at least one of the following:

[0079] 1) receive AIoT operations;

[0081] 3) receive the AIoT operation execution result;

[0082] 4) aggregate the AIoT operation execution result;

That is, in an implementation, the reader device can not only support the function of the reader, but also support other functions; in another implementation, the reader device only supports the function of the reader.

Sometimes, the first communication device is far away from the terminal device, and the first communication device can extend the coverage of the reader / writer through the intermediate device. At this time, the intermediate device is also called a reader / writer or a component of a reader / writer.

[0350] Embodiment one

[0351] In this embodiment, the AIoTF subscribes to the AMF to obtain the UEreader in the target area, and the AMF feeds back the UEreader in the target area. Specifically, the AIoTF can use the "Number of UEs present in a geographical area" or "Presence-In-AOI-Report" event to obtain the UEreader in the target area, and the event parameter UE type is set to UEreader.

[0352] As shown in FIG. 4, the embodiment includes the following steps:

[0353] Step 1: The AIoTF receives the AIoT service related request sent by the AF, such as an inventory request, which contains a target area (Target area). The target area can be the target area in which the AF hopes to perform the related AIoT service.

[0354] Step 2: The AIoTF subscribes to the AMF to the notification event of the UEreader in the Target area, and sends the Namf_EventExposure_Subscribe message to the AMF, which carries the "Number of UEs present in a geographical area" event or the "Presence-In-AOI-Report" event. The parameters of these events include the tracking area identity (TAI) corresponding to the target area, the cell ID, etc., and the UE type is set to the UEreader type.

[0355] Step 3: The AMF receives the subscription event in step 2, identifies the UEreader type UE in the target area, and sends the Namf_EventExposure_Notify to the AIoTF, which carries the detected UEreader or UEreader list.

[0356] Step 4: The AIoTF selects the UEreader according to the UEreader list received in step 3.

[0357] Embodiment two:

[0358] In this embodiment, the AIoTF subscribes to the notification event of the target UE reader entering or leaving the target area to the AMF. When the target UE reader enters the target area, the AMF notifies the AIoTF that the target UE reader enters the target area, and the AIoTF selects the UE reader to perform the AIoT related service. When the target UE reader leaves the target area, the AMF notifies the AIoTF that the target UE reader leaves the target area, and the AIoTF stops the AIoT related service performed by the UE reader.

[0359] As shown in FIG. 5, the embodiment includes the following steps:

[0360] Step 1: The AIoTF receives the AIoT service related request sent by the AF, such as an inventory request, which contains a target UE reader list and a target area. The target UE reader list can be the UE reader that the AF hopes to perform the related AIoT service. The target area can be the target area that the AF hopes to perform the related AIoT service.

[0361] Step 2: The AIoTF subscribes to the notification event of the target UE reader list entering or leaving the target area to the AMF, and sends a Namf_EventExposure_Subscribe message to the AMF, which carries the "UE moving in or out of Area of interest" event. The parameters of the event include the TAI, cell ID, etc. corresponding to the target area, and the UE ID corresponding to the target UE reader list.

[0362] Step 3: The AMF receives the Namf_EventExposure_Subscribe message sent by the AIoTF in step 2, and performs event detection of the target UE entering or leaving the target area.

[0363] Step 4, when detecting that, for example, the target UE reader#1 leaves the target area, the AMF sends Namf_EventExposure_Notify to the AIoTF to indicate the notification that the UE reader#1 leaves the target area, the AIoTF does not select the UE reader#1 to perform the related AIoT service; when detecting that, for example, the target UE reader#2 enters the target area, the AMF sends Namf_EventExposure_Notify to the AIoTF to indicate the notification that the UE reader#2 enters the target area, the AIoTF selects the UE reader#2 to perform the related AIoT service.

[0364] Embodiment Three

[0365] In this embodiment, the AF carries the target area to the AIoTF in the AIoT service request (such as an inventory request), the AIoTF selects an initial UE reader to perform the corresponding AIoT service. Further, the AIoTF subscribes to the AMF for the notification event that the initially selected UE reader leaves the target area, and determines to stop the initially selected UE reader from performing the subsequent AIoT service according to the detection event.

[0366] As shown in FIG. 6, this embodiment includes the following steps:

[0370] Step 4, the AIoTF subscribes to the AMF for the notification event that the UE reader list selected in step 2 leaves the target area, and sends the Namf_EventExposure_Subscribe message to the AMF, the message carrying the "UE moving in or out of Area of interest" event, the parameters of the event including the TAI, cell ID, etc. corresponding to the target area, and the UE ID corresponding to the initial selected UE reader list.

[0371] Step 5, AMF receives the Namf_EventExposure_Subscribe message sent by AIoTF in step 4, and AMF performs the initial selection of UE reader list leaving the target area event detection.

[0372] Step 6, after detecting that the initial selected UE reader #1 has left the target area, AMF sends Namf_EventExposure_Notify to AIoTF to indicate the notification that the UE reader #1 has left the target area.

[0373] Step 7, after receiving the notification in step 6, AIoTF suspends the AIoT service of the UE reader #1, such as initiating the release of the control plane or user plane (PDU session) with the UE reader #1.

[0374] Embodiment Four:
