[0001] The application relates to the field of communications, and more particularly, to a sixth node, a second node, a first node, a third node, and methods performed by the same.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6GHz” bands such as 3.5GHz, but also in “Above 6GHz” bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0061] Figure 1 is an exemplary system architecture 200 according to various embodiments of the present disclosure. Other embodiments of the system architecture 200 can be used without departing from the scope of the present disclosure. User equipment (UE) 201 is a terminal device for receiving data. A next generation radio access network (NG-RAN) 202 is a radio access network, which includes a base station (a gNB or an eNB connected to 5G core network 5GC, and the eNB connected to the 5GC is also called ng-gNB) that provides UE with interfaces to access the radio network. An access control and mobility management function entity (AMF) 203 is responsible for managing mobility context and security information of the UE. A user plane function entity (UPF) 204 mainly provides functions of user plane. A session management function entity SMF 205 is responsible for session management. A data network (DN) 206 includes, for example, services of operators, access of Internet and service of third parties.

[0062] In NR system, in order to support network function virtualization, more efficient resource management and scheduling, a base station (gNB / ng-eNB) that provides a radio network interface for the terminal (UE) can be further divided into a centralized unit gNB-CU / ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit gNB-DU / ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (abbreviated as CU and DU in the present invention), as shown in (a) of Figure 2. gNB-CU has radio resource control (RRC), service data adaptation protocol (SDAP) and packet data convergence protocol (PDCP) protocols, etc, while ng-eNB-CU has RRC and PDCP layers. gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer, etc. There is a standardized public interface F1 between gNB-CU and gNB-DU, and a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU. The F1 interface is divided into control plane F1-C and user plane F1-U. The transport network layer of F1-C is based on IP transport. In order to transmit signaling more reliably, SCTP protocol is added to IP. The protocol of the application layer is F1AP, see 3GPP TS38.473. SCTP can provide reliable application layer message transmission. The transport layer of F1-U is UDP / IP, and GTP-U is used to carry user plane protocol data unit PDU above UDP / IP. Further, for gNB-CU, as shown in (b) of Figure 2, gNB-CU can include gNB-CU-CP (the control plane part of the centralized unit of the base station) and gNB-CU-UP (the user plane part of the centralized unit of the base station). gNB-CU-CP includes the function of the control plane of the base station and has RRC and SDAP protocol layers, and gNB-CU-UP includes the function of the user plane of the base station and has SDAP and PDCP protocol layers. gNB-CU-CP and gNB-CU-UP are standardized public interfaces E1, and the protocol is E1AP, see 3GPP TS38.463. The interface between the control plane part of the centralized unit of the base station and the distributed unit of the base station is F1-C interface, that is, the control plane interface of F1, and the interface between the user plane part of the centralized unit of the base station and the distributed unit of the base station is F1-U interface, that is, the user plane interface of F1. In addition, in the NR system, the base station providing the E-UTRA user plane and control plane which accesses the 5G core network is called ng-eNB. In order to support virtualization, such a base station (ng-eNB) can also be further divided into a centralized unit ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (abbreviated as CU and DU in the present invention), as shown in (c) of Figure 2. ng-eNB-CU has RRC and PDCP layers. gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer,etc. There is a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU. W1 interface is divided into control plane W1-C and user plane W1-U. The transport network layer of W1-C is based on IP transport. In order to transmit signaling more reliably, SCTP protocol is added to IP. The protocol of the application layer is W1AP, see 3GPP TS37.473. The transport layer of W1-U is UDP / IP, and GTP-U is used to carry user plane protocol data unit PDU above UDP / IP.

As shown in Figure 3a, embodiments of the present disclosure may include the following steps:

[0138] The first node transmits first information to the second node, wherein the first information is used to request service related information of the Ambient Internet of Things.

[0139] As an implementation, the first information may include, for example, at least one of the following information:

[0140] - a correlation identification (correlation ID), which is related to a service request of Ambient Internet of Things, for example, is used to identify the service request of the Ambient Internet of Things.

[0141] - first area related information, which is related to an area corresponding to a service request.

[0142] - a first reader list, which is related to a reader identification (for example, it may be a user equipment reader or a base station reader) recommended or suggested or potentially (for simplicity of description, "recommended" will be used collectively below) by the first node to participate in the service request. As an embodiment, the first reader list is a recommended reader list of the second node.

[0143] - first related information, which is related to generating the transaction identification. The name of this information may be used interchangeably with, and may not be limited to, information names such as: Mask, Sequence, Correlation Sequence, Transaction Sequence, Transaction Generation Sequence, and the like. The beneficial effect of this information is that the transaction identification can be generated by the second node based on the correlation identification and the first related information, and the length of the generated transaction identification is shorter than the length of the correlation identification, so that the transaction identification can be used for signaling transmission on the radio interface of the Ambient Internet of Things (for example, the interface between the reader and the Ambient Internet of Things device), and the signaling overhead of the radio interface of the Ambient Internet of Things can be saved.

[0144] - first transaction identification related information, which is related to providing the transaction identification or providing assistance information for determining the transaction identification.

[0145] - base station related information, which is related to other base station or a neighboring base station participating in the same service request of the Ambient Internet of Things (for example, the service request of the Ambient Internet of Things indicated by the above-mentioned correlation identification).

[0146] - first indication information, which is related to that the second node is an initiating node of a subsequent coordination / interaction.

[0147] - second indication information, which is related to the other base station or the neighboring base station participating in the same service request (for example, the service request of the Ambient Internet of Things indicated by the above-mentioned correlation identification).

[0148] - third indication information, which is associated to that the service request is related to positioning. Herein, the services of the Ambient Internet of Things may include location / positioning services, and different services may correspond to different transaction identifications.

[0149] - fourth indication information, which is related to whether the base station allocates the same transaction identification or different transaction identifications to different readers for the service request.

[0150] As an implementation, the first transaction identification related information may include, for example, a transaction identification and information related to the transaction identification selected by the base station or user equipment.

[0151] - a transaction identification, or a selected transaction identification. For example, the transaction identification may be a transaction identification selected by the first node.

[0152] - available transaction identification related information. The base station or user equipment may select a transaction identification based on the available transaction identification related information. The beneficial effect of this information is: the base station or user equipment can better select a transaction identification based on the assistance information provided by the core network, avoiding or ensuring that when the base station or user equipment allocates a transaction identification to a reader, it allocates different readers the same or different transaction identifications. For example, for different services, different readers may need to be allocated the same or different transaction identifications, so the base station or user equipment can better select the transaction identification based on the assistance information provided by the core network. For example, for the first service, it can be avoided that the base station or user equipment allocates different transaction identifications to different readers, and for the second service, it can be ensured that the base station or user equipment allocates different transaction identifications to different readers.

[0153] - used transaction identification related information. The base station or user equipment may select a transaction identification based on the used transaction identification related information. The beneficial effect of this information is: the base station or user equipment can better select a transaction identification based on the assistance information provided by the core network, avoiding or ensuring that when the base station or user equipment allocates a transaction identification to a reader, it allocates different readers the same or different transaction identifications.

[0154] As an implementation, the base station related information may include, for example, at least one of the following information:

[0155] - base station identification information or node identification information or radio access network node identification information (for simplicity of description, "base station identification" is collectively used below to describe), which is related to an identification of at least one of other base stations or neighbouring bases station participating in the same service request (for example, the service request of the Ambient Internet of Things indicated by the above-mentioned correlation identification). In a possible implementation, the base station identification information may be used to indicate the identification of the third node.

[0156] - second area related information, which is related to an area corresponding to other base station or a neighbouring base participating in the same service request. In a possible implementation, the second area related information may be area related information corresponding to the third node.

[0157] - a second reader list, which is related to a reader identification recommended by the first node to participate in the same service request. In a possible implementation, the second reader list may be information related to readers of the third node.

[0158] - first number / quantity related information, which is related to a number of readers of other base station or a neighbouring base participating in the same service request or a number of transaction identifications that other base station or a neighbouring base participating in the same service request needs to allocate. The name of this information may be used interchangeably with, and may not be limited to, the following information names, for example: Number of Readers, Number of Transaction IDs, Number of Transactions, Number of Transaction IDs to be allocated, etc. The beneficial effect of this information is: the base station can better select a transaction identification based on the assistance information provided by the core network, ensuring that when the base station allocates a transaction identification to a reader, it allocates different transaction identifications to different readers.

[0159] As an implementation, the first area related information may include, for example, at least one of the following information:

[0212] In a possible implementation, the third node generates a transaction identification based on the second information (e.g., based on at least one of the correlation identification and the first related information). In a possible implementation of generating a transaction identification, AND operation or OR operation or XOR operation is performed on the correlation identification and the first related information to generate the transaction identification; in another possible implementation method of generating a transaction identification, the most significant X bits of the correlation identification are used as the transaction identification, where X can be a specified number, such as 3 or 4; in another possible implementation method of generating a transaction identification, the least significant X bits of the correlation identification are used as the transaction identification, where X can be a specified number, such as 3 or 4; in another possible implementation of generating a transaction identification, a modulo operation is performed on the correlation identification to generate a transaction identification.

In a possible implementation, if the fourth information may include, for example, the fifth indication information, the first node confirms that allocating a transaction identification to the service request fails or cannot allocate a suitable transaction identification.

[0247] The first node selects readers participating in a service based on the third / fourth area related information and / or third / fourth reader list. It should be noted that the third area related information may be a subset of the first area related information that may be included in the first information, for example; the third reader list may be a subset of the first reader list that may be included in the first information, for example.

[0294] In a possible implementation, the fourth node or the fifth node generates a transaction identification based on the fifth information (for example, based on at least one of the correlation identification and the first related information). In a possible implementation of generating a transaction identification, AND operation or OR operation or XOR operation is performed on the correlation identification and the first related information to generate the transaction identification; in another possible implementation method of generating a transaction identification, the most significant X bits of the correlation identification are used as the transaction identification, where X can be a specified number, such as 3 or 4; in another possible implementation method of generating a transaction identification, the least significant X bits of the correlation identification are used as the transaction identification, where X can be a specified number, such as 3 or 4; in another possible implementation of generating a transaction identification, a modulo operation is performed on the correlation identification to generate a transaction identification.

[0295] In another possible implementation, the fourth node or the fifth node may confirm the selected transaction identification based on the fifth transaction identification related information.

[0346] As an implementation, the reader identification information may include, for example, at least one of the following information:

[0347] information related to a reader identification. For example, a reader identification or other information indicating a reader identification, the reader identification can be a unique identification throughout the network or a mapped reader identification.

[0352] In a possible implementation, the first node initiates a subsequent service request such as an inventory request, a command request, etc. based on the received eighth information.

[0353] Embodiments of the present disclosure provide a method for each node in the Ambient Internet of Things to reasonably interact or respond to Ambient Internet of Things services / transactions, and provide a new method of generating / determining transaction identification in the embodiments of the present disclosure.

[0354] Figure 3j illustrates an example method of one Ambient Internet of Things coordination / interaction, according to the present disclosure. As shown in Figure 3j, the method provided by the embodiment of the present disclosure may include the following steps:

[0355] The second node or the fourth node transmits ninth information to the sixth node, wherein the ninth information is used for the sixth node to decide the occasion to initiate random access, or for counting.

[0356] As an implementation, the ninth information may include, for example, at least one of the following information:

[0357] a transaction identification identifying a transaction.

[0358] a reader identification for identifying a reader.

[0359] a first value related to an occasion at which a random access is initiated, which is used to provide a count value (in one embodiment, it may also be called a "first count value"). The name of this information may be used interchangeably with, and may not be limited to, the following information names, for example: Count / C, Counting Number, Sequence Number / SN, Triggering Value, etc.

[0360] The ninth information may for example be contained in an Ambient Internet of Things radio interface message, the name of this information may be used interchangeably with, and may not be limited to, the following information names, for example: Paging, PagingRep, Paging Repetition, Count Down, Count Up, Counting, etc.

[0361] It should be pointed out that the second node or the fourth node will transmit at least one piece of ninth information to the sixth node. For example, the first value that may be included in the ninth information transmitted each time is greater than the first value that may be included in the ninth information transmitted last time, for example, by 1. That is, the second node or the fourth node will increment the first value in the ninth information transmitted last by 1, and will include the updated first value in the new ninth information and transmit it to the sixth node.

[0362] In a possible implementation, when the first value transmitted last time has been the maximum value (wherein the maximum value of the first value may be determined based on the third value received from the second node or the fourth node, for example, assuming that the third value received from the second node or the fourth node is 4, the maximum value of the first value is determined based on the third value, for example, 15 (ie, 24-1). It can be understood that, the way of determining the maximum value of the first value based on the third value is not limited to this), the first value in the ninth information newly transmitted by the second node or the fourth node may be, for example, 0.

[0363] Before receiving at least one piece of ninth information, the sixth node stores a second value. In a possible implementation, the second value is a random value generated based on a third value received from the second node or a fourth node. For example, assuming that the third value received from the second node or the fourth node is 4, a random number in the range of (0, 15) may be generated as the second value based on the third value, wherein the maximum value of the second value is determined based on the third value, for example, 15 (i.e., 24-1). It can be understood that the method of determining the second value based on the third value and the maximum value of the second value is not limited to this.

[0364] When the sixth node receives a piece of ninth information, compare the first value included in the ninth information with the saved second value:

[0365] The sixth node initiates a random access procedure when the second value is equal to the received first value.

[0366] When the second value is greater than the received first value (or the received first value is less than the second value), the sixth node performs no actions, or waits to receive new ninth information until the received first value equals the second value.

[0367] When the second value is less than the received first value (or the received first value is greater than the second value): in a possible implementation, the sixth node waits to receive new ninth information until the received first value equals the second value, and the sixth node initiates a random access procedure. In another possible implementation, after receiving the updated third value and generating and storing the updated second value based on the updated third value, the sixth node then attempts to initiate a random access, or compares the received first value with the stored second value, and determines whether to initiate a random access procedure based on the comparison result of the first value and the updated second value. In another possible implementation, the sixth node will regenerate a new second value, the new second value being a value between the received first value (e.g. that may or may not, for example, include the received first value) and the maximum of the first value or the second value (e.g. that may or may not, for example, include the maximum of the first value or the second value), and the sixth node stores the new second value.

[0368] If the first value received by the sixth node last time is greater than the first value received this time, and / or if the second value stored by the sixth node is equal to the first value or the maximum value of the second value, in a possible implementation, the sixth node waits to receive new ninth information until the received first value is equal to the second value, and then the sixth node initiates a random access process. In another possible implementation, after receiving the updated third value and generating and storing the updated second value based on the updated third value, the sixth node then attempts to initiate a random access, or compares the received first value with the stored second value, and determines whether to initiate a random access procedure based on the comparison result of the first value and the updated second value.

[0369] It should be pointed out that if the ninth information may include, for example, a reader identification, and if the reader identification matches the reader identification in the paging message received by the sixth node, the sixth node then performs the subsequent comparison process of the first value and the second value; otherwise, the sixth node does not perform the subsequent comparison process between the first value and the second value.

[0370] Embodiments of the present disclosure provide a method for each node to reasonably interact or respond to Ambient Internet of Things services / transactions in the Ambient Internet of Things, and, in the embodiments of the present disclosure, a new method of generating / determining transaction identification is provided. In addition, compared with the process of determining whether to initiate random access by subtracting one from the second value in the prior art, in the present application, the sixth node does not need to subtract one from the second value, thus reducing the burden of the sixth node (for example, the Ambient Internet of Things device).

[0371] Figure 3k illustrates an example method of Ambient Internet of Things coordination / interaction according to the present disclosure. As shown in Figure 3k, embodiments of the present disclosure may include one or more of the following steps:

[0380] Step 9, the fourth node transmits ninth information to the sixth node, and the ninth information is as described in Figure 3j. The ninth information may for example be included in an Ambient Internet of Things radio interface message paging response (PagingRep).

[0381] Embodiments of the present disclosure provide a method for each node to reasonably interact or respond to Ambient Internet of Things services / transactions in the Ambient Internet of Things, and, in the embodiments of the present disclosure, a new method of generating / determining transaction identification is provided. In addition, compared with the process of determining whether to initiate random access by subtracting one from the second value in the prior art, in the present application, the sixth node does not need to subtract one from the second value, thus reducing the burden of the sixth node (for example, the Ambient Internet of Things device).

[0382] Fig. 3l illustrates an example method of Ambient Internet of Things interaction according to the present disclosure. As shown in Figure 3l, an embodiment of the present disclosure may include one or more of the following steps:

[0383] Step 1, a first node transmits an inventory request message to a second node.

[0384] Step 2, the second node transmits an inventory response message to the first node.

[0385] Step 3, the second node transmits tenth information to the first node, and the tenth information is used to indicate Inventory Complete.

[0386] As an embodiment, the tenth information may include information related to an Inventory Complete Indication, for example. The name of this information can be used interchangeably with the following information names, and may not be limited to the following information names, such as: Inventory Complete Indication，Inventory Complete Indicator，Inventory End Indication，Inventory End Indicator，Complete Indication，Complete Indicator，End Indication，End Indicator , etc.

[0387] The tenth information may, for example, be included in an NG interface application layer protocol message, such as an Inventory Report message, an AIoT Session Release Request message, an AIoT Session Notify message, and the like.

[0388] In one possible implementation, if the inventory request message does not contain a Follow on Command Indication (hereinafter, it will be described by "Follow on Command Indication"), the second node will release or directly release the context and / or resources related to the related Ambient Internet of Things session after transmitting the tenth information. In this case, after receiving the tenth information, the first node terminates / ends all activities of the related Ambient Internet of Things session and / or releases the context and / or resources related to the related Ambient Internet of Things session.

[0389] In another possible embodiment, if the inventory request message contains information related to Group Device(s) or information related to All Device(s) and does not contain a Follow on Command Indication, the second node releases or directly releases the context and / or resources related to the related Ambient Internet of Things session after transmitting the tenth information. In this case, after receiving the tenth information, the first node terminates / ends all activities of the related Ambient Internet of Things session and / or releases the context and / or resources related to the related Ambient Internet of Things session.

[0390] In another possible embodiment, if the inventory request message contains information related to a Single Device, the second node releases or directly releases the context and / or resources related to the related Ambient Internet of Things session after transmitting the inventory report message. In this case, after receiving the inventory report message, the first node terminates / ends all activities related to the Ambient Internet of Things session and / or releases the context and / or resources related to the related Ambient Internet of Things session, regardless of whether the inventory report message contains the tenth information or not.

[0391] Embodiments of the present disclosure provide a method for releasing an Ambient Internet of Things session between a base station and a core network in the Ambient Internet of Things, which can reduce the interaction between the base station and the core network about releasing the Ambient Internet of Things session.

[0392] Figure 3m illustrates an example method of Ambient Internet of Things interaction according to the present disclosure. As shown in Figure 3m, embodiments of the present disclosure may include one or more of the following steps:

[0393] Step 1, the second node transmits a setup request message to the first node, which is used for the request of setting up an interface (including but not limited to NG), wherein the setup request message contains the related information that the second node supports AIoT Radio and Uu Radio.

[0394] Step 2, the first node transmits eleventh information to the second node, and the eleventh information is related information used to indicate the first node to respond or accept the setup.

[0395] As an embodiment, the eleventh information may include at least one of the following information, for example:

[0396] - response to setup related indication information. The name of this information can be used interchangeably with the following information names, and may not be limited to the following information names, such as: AIoT Support Response，AIoT Support Response Indication / Indicator，Radio Setup Response，Radio Setup Response Indication / Indicator，AIoT Support Accepted，AIoT Support Accepted Indication / Indicator，Radio Accepted，Radio Accepted Indication / Indicator，AIoT Support, etc.

[0398] As an embodiment, the response to setup related indication information includes at least one of the following information:

[0399] - response only to AIoT setup related indication information. The possible names of the indication include but are not limited to: AIoT only，AIoT Radio only，AIoT Response only，AIoT Radio Response only，AIoT Accepted only，AIoT Radio Accepted only, etc.

[0402] The eleventh information may, for example, be included in an NG interface application layer protocol message, such as an NG setup response message, an NG setup failure message, and the like.

[0403] The first node determines the radio that can be received / accepted or responded after receiving the related information that the second node supports the AIoT Radio and Uu Radio, and transmits the related indication information of the received / accepted or responded radio to the second node through the eleventh information.

[0404] If the response to setup related indication information is contained in the NG setup response message: if the response to setup related indication information received by the second node contains or sets the response only to AIoT setup related indication information, the second node ignores the non-applicable information elements also contained in the NG setup response message.

[0405] If the response to setup related indication information is included in the NG setup response message: if the response to setup related indication information received by the second node contains or sets the response only to New Radio (NR) setup related indication information, the second node considers that the NG interface cannot perform the interaction of the related processes / procedures of Ambient Internet of Things, or does not interact the related processes / procedures of Ambient Internet of Things, and / or applies or stores the information element contained in the NG setup response message.

[0406] If the response to setup related indication information is included in the NG setup response message: if the response to setup related indication information received by the second node contains or sets the response to AIoT and New Radio (NR) setup related indication information, the second node considers that the first node accepts or supports the Ambient Internet of Things related signaling or process interaction / procedure exchange, and accepts or supports the new radio related signaling or process interaction / procedure exchange, and / or applies or stores the information element contained in the NG setup response message.

[0407] If the support or response to AIoT related indication information contains a NG setup response message or a NG setup failure message:

[0408] In a possible embodiment, the support or response to AIoT related indication information contains two code points: Support and Not Support. If the support or response to AIoT related indication information received by the second node contains a code point indicating Support, the second node considers that the first node accepts or supports the Ambient Internet of Things related signaling or process interaction / procedure exchange, and / or applies or stores the information element contained in the NG setup response message. If the support or response to AIoT related indication information received by the second node contains a code point indicating Not Support, the second node considers that the NG interface cannot perform the interaction of the related processes / procedures of Ambient Internet of Things, or does not interact the related processes / procedures of Ambient Internet of Things.

[0409] In another possible embodiment, the support or response to AIoT related indication information contains two code points: True and False. If the support or response to AIoT related indication information received by the second node contains a code point indicating True, the second node considers that the first node accepts or supports the Ambient Internet of Things related signaling or process interaction / procedure exchange, and / or applies or stores the information element contained in the NG setup response message. If the support or response to AIoT related indication information received by the second node contains a code point indicating False, the second node considers that the NG interface cannot perform the interaction of the related processes / procedures of Ambient Internet of Things, or does not interact the related processes / procedures of Ambient Internet of Things.

[0410] In another possible embodiment, the support or response to AIoT related indication information includes one code point indicating Support. If the NG setup response message or the NG setup failure message received by the second node includes the support or response to AIoT related indication information, the second node considers that the first node accepts or supports the Ambient Internet of Things related signaling or process interaction / procedure exchange, and / or applies or stores the information element contained in the NG setup response message; If the NG setup response message or the NG setup failure message received by the second node does not include the support or response to AIoT related indication information, the second node considers that the NG interface cannot perform the interaction of the related processes / procedures of Ambient Internet of Things, or does not interact the related processes / procedures of Ambient Internet of Things.

[0411] In another possible embodiment, the support or response to AIoT related indication information includes one code point indicating True. If the NG setup response message or the NG setup failure message received by the second node includes the support or response to AIoT related indication information, the second node considers that the first node accepts or supports the Ambient Internet of Things related signaling or process interaction / procedure exchange, and / or applies or stores the information element contained in the NG setup response message; If the NG setup response message or the NG setup failure message received by the second node does not include the support or response to AIoT related indication information, the second node considers that the NG interface cannot perform the interaction of the related processes / procedures of Ambient Internet of Things, or does not interact the related processes / procedures of Ambient Internet of Things.
