[0078] In an embodiment of the present disclosure, an activation method may be defined for an ambient IoT device in a topology with downlink assistance (such as shown in FIG. 2 a and FIG. 2 b above).

[0079] FIG3a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3a, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The method includes:

[0080] Step S3101: The first node determines that the second node is to be activated.

[0081] In some embodiments, the first node may be, for example, a repeater, an IAB node, a terminal, a transponder, a backscatter receiver, or the like.

[0082] In some embodiments, the first node may also be referred to as an auxiliary node.

[0083] In some embodiments, the second node may be, for example, a node that is activated or to be activated, and the second node may be, for example, an Ambient IoT device, and some of the one or more Ambient IoT devices are to be activated.

[0084] In some embodiments, “activation” may refer to controlling the second node to change from an idle state to an activated state, or from a deactivated state to an activated state.

[0085] In some embodiments, the first node may determine that the second node is to be activated upon receiving activation request information, where the activation request information is used to request activation of the second node, thereby enabling subsequent activation of the second node.

[0086] In some embodiments, the third node may determine that the second node is to be activated, and the third node may request the first node to activate the second node through activation request information.

[0087] In some embodiments, the third node is an ambient power-enabled node in the ambient Internet of Things.

[0088] In some embodiments, the third node is, for example, an Ambient IoT device that triggers activation of the second node.

[0089] In some embodiments, if there are multiple Ambient IoT devices waiting to be activated, the Ambient IoT device that triggers the activation may be an already activated Ambient IoT device.

[0090] In some embodiments, if a third node initiates activation, the third node may send an activation request message to the first node, where the activation request message is used to request activation of the second node. The first node may receive the activation request message sent by the third node, thereby subsequently activating the second node.

[0091] In some embodiments, the determination that the second node is to be activated may be made by different network elements. In other words, activation of the second node may be initiated by multiple (or a variety of) network elements. For example, the determination that the second node is to be activated, i.e., the initiation of the activation process for the second node, may be made by an access network, a core network, a third-party server, the second node, or a third node different from the second node.

[0092] In some embodiments, the access network device may determine that the second node is to be activated, and the access network device may request the first node to activate the second node through activation request information.

[0093] In some embodiments, if the access network device initiates activation, the access network device may send activation request information to the first node for requesting activation of the second node, and the first node may receive the activation request information sent by the access network device.

[0094] In some embodiments, the core network device may determine that the second node is to be activated, and the core network device may request the first node to activate the second node through activation request information.

[0095] In some embodiments, if the core network device initiates activation, the core network device may send activation request information for requesting activation of the second node to the first node, and the first node may receive the activation request information sent by the core network device.

[0096] In some embodiments, if the third-party server initiates activation, it may trigger the core network device to send activation request information for requesting activation of the second node to the first node, and the first node may receive the activation request information sent by the core network device.

[0097] In some embodiments, the activation request information may be carried in an activation request message (Activation Request), and sent by the third node or the access network device or the core network device to the first node.

[0098] In some embodiments, the second node and the third node may be the same node or different nodes. That is, in some embodiments, Ambient IoT 1, as the second node, may initiate the activation process for itself, while in other embodiments, another Ambient IoT different from Ambient IoT 1 (e.g., Ambient IoT 2) may initiate the activation process for Ambient IoT 1.

[0099] In some embodiments, the first node may also detect a second node to be activated in the surrounding environment. Optionally, the first node may also initiate an activation process for the second node.

[0100] In some embodiments, if the first node determines that the node has been authorized or authenticated, it may determine a second node in the surrounding environment to be activated.

[0101] In some embodiments, if the first node determines that the second node has been authorized or authenticated, the first node may determine that the second node is to be activated.

[0102] In some embodiments, if the first node determines that it and the second node have been authorized or authenticated, the first node may determine that the second node is to be activated.

[0103] Therefore, when the first node determines that it has received activation request information for requesting activation of the second node, and / or discovers that the second node is to be activated, and / or determines that the first node and / or the second node have been authorized or authenticated, it can determine that the second node is to be activated, thereby flexibly and accurately determining the second node to be activated, and is effectively applicable to personalized communication scenarios.

[0104] In an embodiment of the present disclosure, the first node can receive activation request information sent by a third node, wherein the third node initiates activation; and / or receive activation request information sent by an access network device, wherein the access network device initiates activation; and / or receive activation request information sent by a core network device, wherein the core network device and / or a third-party server initiates activation, which can be effectively applied to personalized activation scenarios and meet the personalized activation requirements of a variety of different communication devices.

[0105] In some embodiments, the activation request information includes at least one of the following: a device identifier of the third node; a device type of the third node; a group identifier of the third node; a location of the third node; a capability of the third node; a first indication information, wherein the first indication information is used to indicate the situation of activating the service of the second node; a second indication information, wherein the second indication information is used to indicate whether the excitation signal is sent periodically; a second node list, wherein the second node list includes at least one of the device identifier of the second node, the group identifier of the second node, the device type of the second node, the location of the second node, and the capability of the second node.

[0106] In some embodiments, the device identifier of the third node is used to uniquely identify the third node.

[0107] In some embodiments, the group identifier of the third node is used to identify the group to which the third node belongs, and the group may include multiple third nodes.

[0108] In some embodiments, the device type of the third node may be any one of the device type A, device type B, and device type C described above.

[0109] In some embodiments, the position of the third node describes the absolute position or relative position of the third node.

[0110] In some embodiments, the capabilities of the third node, such as the device capabilities of the third node, may specifically include: energy storage capabilities, signal generation capabilities, data processing capabilities, supported protocol stacks, supported topology types, supported signal types, etc.

[0111] In some embodiments, the device identifier of the second node is used to uniquely identify the second node.

[0112] In some embodiments, the group identifier of the second node is used to identify the group to which the second node belongs, and the group may include multiple second nodes.

[0113] In some embodiments, the device type of the second node may be any one of the device type A, device type B, and device type C described above.

[0114] In some embodiments, the position of the second node describes the absolute position or relative position of the second node.

[0115] In some embodiments, the capabilities of the second node, such as the device capabilities of the second node, may specifically include: energy storage capabilities, signal generation capabilities, data processing capabilities, supported protocol stacks, supported topology types, supported signal types, etc.

[0116] Thus, the first node can accurately learn that the second node is to be activated based on the obtained activation request information, and initiate activation of the second node in a timely manner, thereby improving the timeliness and efficiency of activation.

[0117] Step S3102: The first node sends an excitation signal to the second node.

[0118] In some embodiments, the stimulation signal is used to activate the second node.

[0119] In some embodiments, when the first node determines that the second node is to be activated, the first node may send a signal to the second node. The signal may be used to activate the second node, and the signal may be referred to as an excitation signal.

[0120] In some embodiments, the excitation signal may not carry information, and may be a pulse signal, an excitation signal, a modulated signal, or an unmodulated signal, or the excitation signal may be a signal carrying information, and the information carried may be used to activate the second node.

[0121] In some embodiments, the excitation signal may include: the device identification of the first node, the group identification of the first node, the device type of the first node, the location of the first node, the capability of the first node, the device identification of the second node, the group identification of the second node, the device type of the second node, the location of the second node, the capability of the second node, the first indication information, and one or more of the second indication information, wherein the first indication information is used to indicate the situation of activating the service of the second node, and the second indication information is used to indicate whether the excitation signal is sent periodically, thereby effectively improving the comprehensiveness of the excitation signal indication.

[0122] In some embodiments, the device identifier of the first node is used to uniquely identify the first node.

[0123] In some embodiments, the group identifier of the first node is used to identify the group to which the first node belongs, and the group may include multiple first nodes.

[0124] In some embodiments, the device type of the first node may be any one of the device type A, device type B, and device type C described above.

[0129] In some embodiments, the first indication information may be, for example, a service code.

[0130] In some embodiments, the second indication information may be, for example, a service cycle.

[0131] Step S3103: The second node verifies the excitation signal according to the verification information.

[0132] In some embodiments, the activated Ambient IoT device may receive an excitation signal sent by the auxiliary node.

[0133] In some embodiments, the verification information refers to information used to verify the excitation signal.

[0134] In some embodiments, the verification information may be configured locally or pre-configured by an auxiliary node or a core network device.

[0135] In some embodiments, the verification information may also be used to verify information carried by the excitation signal.

[0136] In some embodiments, the excitation signal, service code, service cycle, device identification of the first node, etc. may be verified. After the verification is passed, it may indicate that the second node allows itself to be activated.

[0137] Step S3104: The second node determines that the verification is passed and switches to the active state.

[0138] In some embodiments, when the excitation signal passes verification according to the verification information, the state may be switched to the activation state.

[0139] In some embodiments, if the excitation signal fails to be verified according to the verification information, the next excitation signal may be monitored.

[0140] In some embodiments, the second node may be switched from an idle state to an active state, or from a deactivated state to an active state.

[0141] In some embodiments, after being activated, the second node can meet the requirements of some services, such as meeting the requirements of the service that initiates the activation.

[0142] Step S3105: The second node sends second activation response information to the access network device, where the second activation response information is used to indicate the activation status of the second node.

[0143] In some embodiments, the information indicating the activation of the second node may be referred to as second activation response information.

[0146] Step S3106: The access network device sends first activation response information to the first node or the core network device.

[0147] In some embodiments, the first activation response information is used to indicate that the second node has been activated.

[0148] In some embodiments, after learning that the second node has been activated, the access network device may indicate to the first node that the second node has been activated, or may also indicate to the core network device that the second node has been activated.

[0149] In some embodiments, the information indicating that the second node has been activated may be referred to as first activation response information.

[0152] In some embodiments, the state of the second node indicates that the second node is currently in an activated state.

[0153] Step S3107: The first node sends first activation response information to the third node.

[0154] In some embodiments, if the activation is initiated by a core network device, the core network may directly store the first activation response information locally, or update the locally stored content, such as updating the status of the second node stored locally.

[0155] In some embodiments, if the activation is initiated by a third-party server, the core network may forward the first activation response information to the third-party server, so that the third-party server can promptly and accurately learn that the second node has been activated.

[0156] In the disclosed embodiment, the auxiliary node may send an excitation signal to the Ambient IoT device.

[0157] In the embodiment of the present disclosure, the base station may receive an incentive response message from the Ambient IoT device.

[0278] In step 3, based on the results of authorization and authentication in step 2, the auxiliary node decides to activate the target environment IoT device.

[0279] In some embodiments, the activation may be initiated by the auxiliary node in this step, or may be triggered by other devices described in step 1.

[0280] In step 4, if the auxiliary node does not have enough information to activate the Ambient IoT device (for example, the information in step 1 is insufficient, or step 1 is not executed and the information is insufficient (the information can be configured locally or by the network or stored in the last auxiliary node used)), the auxiliary node can request auxiliary information to help discover the Ambient IoT device to be activated. The Ambient IoT device to be activated may have a specific Quality of Service (QoS) in a specific area and time.

[0281] In some embodiments, the core network device may receive an assistance information request message sent by the auxiliary node and provide the auxiliary node with a candidate request device list (an optional example of a second node list, which may include information about one or more second nodes to be activated) through the base station. The candidate request device list may include the device number, device ID, group ID, location, and capabilities of each target environment IoT device.

[0282] In step 5, the auxiliary node sends an excitation signal to activate the target environment IoT device.

[0283] In some embodiments, the excitation signal can be a modulated signal or an unmodulated signal. The excitation signal can be a simple excitation signal without information, or it can carry information such as the device ID of the auxiliary node, the device type of the auxiliary node, the service code, and the service cycle.

[0284] In some embodiments, the target environment IoT device can be activated by an excitation signal.

[0285] In some embodiments, the target environment IoT device can be activated from an idle state to an active state, or from a deactivated state to an active state, or can be activated conditionally.

[0286] In some embodiments, the target environment IoT device may also verify the information contained in the excitation signal, for example, verify the service code, verify the service cycle, verify the device ID, etc.

[0287] In some embodiments, the verification information may be configured locally or pre-configured by an auxiliary node or a core network.

[0288] In step 6, the target environment IoT device may send an incentive response message to the base station.

[0289] In some embodiments, the stimulus response message can be a backscattered signal of the stimulus signal (when the device type of the target environment IoT device is device type A or device type B), or it can be a signal generated by the target environment IoT (when the device type of the target environment IoT device is device type C).

[0290] In some embodiments, the incentive response message may carry the incentive result (success or failure), the reason for failure (if failed), the status of the environmental IoT device, the device ID of the environmental IoT device, the group ID of the environmental IoT device, the device type of the environmental IoT device, the function of the environmental IoT device, and all the aforementioned information of the target environmental IoT device, etc.

[0291] In some embodiments, the stimulus response message can be sent optionally (for example, when the stimulus signal is received, only the activated target environment IoT device sends it or not, or all environment IoT devices send it or not), or it can be sent conditionally (for example, only the target environment IoT device that fails to activate or only the target environment IoT device that succeeds in activation sends it).

[0292] In step 7, in some embodiments, the base station and / or the core network device may obtain an incentive response message.

[0293] Example A:

[0294] In some embodiments, the stimulus response message may be transparent to the base station. The base station may forward the stimulus response message to the core network device, and the core network device may respond with a target Ambient IoT list to the base station.

[0295] In some embodiments, the core network device may send an incentive response message (which may include an incentive response message and / or a list of target environment IoT devices) to the base station.

[0296] In some embodiments, if multiple target environment IoT devices are involved, the base station may forward the stimulus response message to the core network device immediately after receiving the stimulus response message, or package multiple stimulus response messages into one message until the stimulus response messages sent by all target environment IoT devices are received or the relevant timer expires (marking the result as failure due to activation failure). In this case, the stimulus response message can be transmitted to the core network device and then transmitted to the base station.

[0297] Example B:

[0298] In some embodiments, the base station may receive an incentive response message.

[0299] In some embodiments, after receiving the stimulus response message, the base station may store the information contained in the stimulus response message in the activation response message.

[0300] In some embodiments, if all stimulus response messages are received or the timer is completed (the result is marked as failure and the reason is marked as activation failure), the base station may choose to send an activation response message to the core network device. The core network device may store and update the information of the target Ambient IoT device and respond to the base station with a list of information of the target Ambient IoT device.

[0301] In some embodiments, if the core network device obtains information about the target environment IoT device, the following step 8c may not be performed.

[0302] In some embodiments, if the core network device further opens it to a third-party server, the following step 8d may not be performed.

[0303] In some embodiments, if the core network device obtains the target Ambient IoT device information in step 7 and the request in step 2 does not include the target Ambient IoT device information, the core network device may further authorize and authenticate the target Ambient IoT device. The result may be included in the activation response message in step 8.

[0304] In step 8a, the base station may send an activation response message to the ambient IoT device through the auxiliary node.

[0305] In some embodiments, the auxiliary node may also store the information contained in the activation response message.

[0306] In some embodiments, the information may be generated from a base station or from a core network device in step 7.

[0307] In some embodiments, the activation response message may include information about each target environment IoT device, such as the device ID of the target environment IoT device, the group ID of the target environment IoT device, the location of the target environment IoT device, the device type of the target environment IoT device, the function of the target environment IoT device, and the status of the environment IoT device.

[0308] In step 8b, the base station may send an activation response message to the auxiliary node.

[0309] In step 8c, if the base station does not send an activation response message in step 7 (example B), the base station may send an activation response message to the core network device.

[0310] In step 8d, if the base station does not send an incentive response message in step 7, the base station may send an activation response message to the core network device, and the core network device is open to the third-party server.
