Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for activating or deactivating a resource. Background Technology

[0002] In small data transmission (SDT) scenarios without anchor relocation, serving nodes can allocate resources, such as sounding reference signal (SRS) resources, to inactive terminal devices.

[0006] Send the resource control information to the service node.

[0007] In this disclosure, the anchor node sends the resource control information to the service node after determining the resource control information for activating or deactivating resources corresponding to a specified terminal device in an RRC inactive state.

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0054] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0055] 1. Sounding reference signal (SRS)

[0056] In wireless communication, the Sounding Reference Signal (SRS) is used to estimate uplink channel frequency domain information for frequency-selective scheduling, or to estimate downlink channel information for downlink beamforming. As an uplink signal, terminal devices transmit SRS to help network devices obtain channel state information for each user. In 5G systems, SRS can be used for resource scheduling, link adaptation, massive MIMO, and beam management.

[0057] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown is an example comprising two network devices, namely a service node 11, an anchor node 12, and a terminal device 13.

[0058] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0059] The service node 11 and anchor node 12 in this disclosure include evolved NodeBs (eNBs), transmission reception points (TRPs), next-generation NodeBs (gNBs) in NR systems, base stations in other future mobile communication systems, or access nodes in wireless fidelity (WiFi) systems. This disclosure does not limit the specific technologies or device forms used in the network devices. The network devices provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layers of network devices, such as base stations, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0060] The terminal device 12 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0061] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0062] Typically, in SDT (Single-Touch Targeting) scenarios without anchor relocation, when a terminal device is inactive, it may move to a new network node, namely the serving gNB (or receiving gNB). The serving gNB can allocate resources to the terminal device, such as SRS resources. However, since the terminal device's context information is still stored in the anchor gNB, and the anchor gNB cannot directly activate or deactivate the resources allocated in the serving gNB, this may lead to the terminal device's relocation failing.

[0063] In this disclosure, the anchor node can send activation or deactivation information to the service node, so that the service node can activate or deactivate the resources of the terminal device in an inactive state based on the information. This avoids location activation failures and improves the reliability of location.

[0064] It should be noted that, in this disclosure, any method for activating or deactivating a resource provided in any embodiment can be executed alone, or can be executed together with possible implementation methods in other embodiments, or can be executed together with any technical solution in related technologies.

[0065] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0066] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0067] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0068] Depending on the context, the words “if” and “in response to” used here can be interpreted as “when”, “when”, or “in response to determination”.

[0069] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0070] In this disclosure, the serving gNB may also be referred to as the receiving gNB or the new NG-RAN node, and the anchor gNB may also be referred to as the last serving gNB or the old NG-RAN node.

[0071] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by an anchor node. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0072] Step 201: Determine the resource control information corresponding to the specified terminal device. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device that is in the inactive state of radio resource control (RRC).

[0073] Optionally, resource control information includes at least one of the following:

[0074] Resource activation information, wherein the resource activation information is used to activate the resources corresponding to the specified terminal device; and

[0075] Resource deactivation information, wherein the resource activation information is used to deactivate the resources corresponding to the specified terminal device.

[0076] In this disclosure, the resource control information may include resource activation information for activating resources. Anchor nodes can determine the resource activation information corresponding to a specified terminal device based on received information related to the location of that specified terminal device. They then instruct service nodes to reserve resources to be activated and to activate the resources corresponding to the specified terminal device according to the resource activation information. Thus, the specified terminal device can begin using the corresponding resources for location services, thereby avoiding location activation failures and improving location reliability.

[0077] Alternatively, the resource control information may include resource deactivation information for deactivating resources. When an anchor node determines that a specified terminal device has accessed from another network node, it can determine the resource deactivation information corresponding to that terminal device. This instructs the service node to release the resources to be deactivated and to deactivate the resources corresponding to the specified terminal device. As a result, the terminal device can stop using the activated resources for positioning, thus avoiding resource waste.

[0078] Optionally, the resource activation information in the resource control information includes at least one of the following: the identifier of the designated terminal device, the identifier of the probe reference signal SRS resource set, the SRS resource identifier, information on the spatially related resources between the SRS to be activated, the first activation time, the first activation duration, and a first indication for instructing the service node whether to send the resource control information and the RRC release message to the designated terminal device simultaneously.

[0079] The identifier for the designated terminal device can be any information that can uniquely identify the designated terminal device, such as the terminal device's serial number. The identifier for the Sound Reference Signal (SRS) resource set can be any information that can uniquely identify the designated SRS resource set, such as the SRS resource set's serial number. The identifier for the SRS resource can be any information that can uniquely identify the designated SRS resource, such as the SRS resource's serial number. The information about resources spatially related to the SRS to be activated can be any other information that has a spatial relationship with the SRS to be activated, such as the identifier of other signals spatially related to the SRS to be activated.

[0080] Optionally, the resource deactivation information in the resource control information includes at least one of the following: the identification information of the specified terminal device, the identifier of the deactivated SRS resource, the identifier of the deactivated SRS resource set, and the deactivation indication.

[0081] The deactivation instruction can be used to instruct the deactivation of resources corresponding to a specified terminal device. For a detailed explanation of the terminal device identifier, SRS resource identifier, and SRS resource set identifier, please refer to the detailed description of any embodiment of this disclosure, which will not be repeated here.

[0082] Step 202: Send resource control information to the service node.

[0083] In this disclosure, the anchor node can send resource activation information to the service node. Subsequently, the service node can identify the designated terminal device based on the identifier of the designated terminal device in the resource activation information and send the resource activation information to the designated terminal device. Thus, the designated terminal device can activate the SRS resource indicated in the resource activation information at a first activation time, maintain the SRS resource in an active state during the first activation duration, and actively deactivate the SRS resource after the first activation duration. This avoids the need for additional deactivation signaling to activate the SRS resource, preventing resource waste.

[0084] Alternatively, the service node can identify the specified terminal device based on the identifier of the specified terminal device in the resource deactivation information, and then deactivate the resources of the specified terminal device. This avoids resource waste.

[0085] Optionally, resource control information may be included in at least one of the following messages sent to the serving node: a terminal device context retrieval failure message, a radio access network (RAN) paging message, an Xn interface application procedure protocol message, a terminal device context retrieval confirmation message, a location activation request message, and a location deactivation request message.

[0086] In this disclosure, the anchor node sends the resource control information to the service node after determining the resource control information for activating or deactivating resources corresponding to a specified terminal device in an RRC inactive state. Thus, the service node can activate or deactivate the resources corresponding to the specified terminal device based on the resource control information, avoiding activation or deactivation failures and resource waste, thereby improving positioning reliability.

[0087] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by an anchor node. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0088] Step 301: Receive the location activation request for the specified terminal device sent by LMF.

[0089] For a detailed description of the specified terminal device, please refer to the detailed description of any implementation example of this disclosure, which will not be repeated here.

[0090] In this disclosure, when the location management function (LMF) determines that location information is needed, such as when the currently acquired location information is insufficient to accurately locate the position of a specified terminal device, it can send a location activation request for the specified terminal device to the anchor node to obtain the location information of the specified terminal device. The location activation request may include information such as the identifier of the specified terminal device, and this disclosure does not limit this information.

[0091] Step 302: Determine the resource activation information corresponding to the specified terminal device based on the location activation request sent by the LMF node for the specified terminal device.

[0092] For a detailed description of the resource activation information, please refer to the detailed description of any embodiment of this disclosure, and it will not be repeated here.

[0093] In this disclosure, the anchor node can determine the specified terminal device based on the identifier of the specified terminal device in the location activation request for the specified terminal device, and then generate the resource activation information corresponding to the specified terminal device.

[0094] Step 303: Send resource activation information to the service node.

[0095] The specific process of step 303 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0096] In this disclosure, after receiving a location activation request for a specified terminal device from the LMF node, the anchor node can determine the resource activation information corresponding to the specified terminal device based on the request, and then send the resource activation information to the service node. Thus, the service node can activate the resources corresponding to the specified terminal device based on the resource control information, avoiding location activation failure and improving location reliability.

[0097] Please see Figure 4 , Figure 4 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by an anchor node. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0098] Step 401: Receive a location deactivation request for a specified terminal device sent by LMF.

[0099] For a detailed description of the specified terminal device, please refer to the detailed description of any implementation example of this disclosure, which will not be repeated here.

[0100] In this disclosure, when the LMF determines that it does not need to obtain location information—for example, when the currently obtained location information is sufficient to accurately locate the position of the specified terminal device—it can send a location deactivation request for the specified terminal device to the anchor node to avoid wasting resources on unnecessary location tracking. The location deactivation request may include information such as the identifier of the specified terminal device, and this disclosure does not limit its scope.

[0101] Step 402: Based on the location deactivation request for the specified terminal device sent by the LMF node, determine the resource deactivation information corresponding to the specified terminal device.

[0102] For a detailed description of the resource activation information, please refer to the detailed description of any embodiment of this disclosure, and it will not be repeated here.

[0103] In this disclosure, the anchor node can determine the specified terminal device based on the identifier of the specified terminal device in the location activation request for the specified terminal device. Then, it can determine the resources corresponding to the specified terminal device and generate resource deactivation information corresponding to the specified terminal device to instruct the service node to release the resources corresponding to the specified terminal device.

[0104] Optionally, when a designated terminal device sends a Radio Resource Control (RRC) recovery request to the anchor node through another network node, it indicates that the designated terminal device has stopped using the corresponding resource. At this time, the resource deactivation information corresponding to the designated terminal device can be determined based on the RRC recovery request.

[0105] Optionally, when a designated terminal device sends a Radio Resource Control (RRC) connection request to access the anchor node through another network node, it indicates that the designated terminal device has stopped using the corresponding resource. At this time, the resource deactivation information corresponding to the designated terminal device can be determined based on the RRC connection request.

[0106] Step 403: Send resource deactivation information to the service node.

[0107] The specific process of step 403 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0108] In this disclosure, after receiving a location deactivation request for a specified terminal device from the LMF, the anchor node can determine the resource deactivation information corresponding to the specified terminal device based on the received request. Then, it can send the resource deactivation information to the service node. Thus, the service node can activate the resources corresponding to the specified terminal device based on the resource control information, thereby avoiding resource waste.

[0109] Please see Figure 5 , Figure 5 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by an anchor node. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0110] Step 501: Receive a location activation request for the specified terminal device sent by LMF.

[0111] Step 502: Determine the resource activation information corresponding to the specified terminal device based on the location activation request sent by the LMF node for the specified terminal device.

[0112] Step 503: Send resource control information to the service node.

[0113] The specific processes of steps 501-503 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0114] Step 504: Receive activation feedback information sent by the service node.

[0115] The activation feedback information may include at least one of the following: a second activation time and a second activation duration. The second activation time is the SRS activation time determined by the service node, and the second activation duration is the SRS activation duration determined by the service node.

[0116] In this disclosure, when a service node receives resource activation information from an anchor node, if the resource activation information does not include time-related information, such as a first activation time and a first activation duration, then the service node can determine relevant time information for resource activation, such as a second activation time and a second activation duration. Alternatively, if the resource activation information includes time-related information, the service node can also determine, based on the actual network conditions, whether to activate the resources of the specified terminal device according to the first activation time and the first activation duration in the resource control information. If the service node determines not to activate the resources of the specified terminal device according to the first activation time and the first activation duration in the resource control information, it can determine the second activation time and the second activation duration itself. After determining the second activation time and the second activation duration, the service node can send an activation feedback message to the anchor node to synchronize the second activation time and the second activation duration. It is understood that the second activation time and the first activation time can be the same or different, and the second activation duration and the first activation duration can be the same or different.

[0117] Optionally, the anchor node can also receive deactivation feedback information sent by the service node.

[0118] In this disclosure, when the service node receives the resource deactivation information sent by the anchor node, the service node activates the resources of the specified terminal device according to the resource control information, or it can re-determine the deactivation time according to the actual network conditions, and can send deactivation feedback information to the anchor node to synchronize the deactivation time and other information with the anchor node.

[0119] Optionally, activation feedback information or deactivation feedback information may be sent to the service node in at least one of the following messages: failure to retrieve terminal device context message, RAN paging message, Xn interface application process protocol message, retrieval of terminal device context confirmation message, location activation request message, location deactivation request message, etc.

[0120] Step 505: Send a location activation feedback message to the LMF node.

[0121] In this disclosure, when the anchor node receives a location activation request from the LMF, it can send a location activation feedback message to the LMF node to synchronize the LMF's location activation-related configuration. Therefore, the LMF can use the location activation feedback message to locate the corresponding network node to send a location measurement request to obtain the location information of the specified terminal device. The location activation feedback message and the activation feedback information can be the same or partially the same.

[0122] Optionally, when the anchor node receives a location deactivation request from the LMF, it can send a location deactivation feedback message to the LMF node to synchronize the LMF location deactivation related configuration.

[0123] In this disclosure, after receiving a location activation request for a specified terminal device from the LMF, the anchor node can determine the resource activation information corresponding to the specified terminal device based on the request, and send resource control information to the service node. Subsequently, it can receive activation feedback information from the service node and send a location activation feedback message to the LMF node. Thus, by exchanging activation resource-related information among network nodes, location activation failures are avoided while ensuring accuracy, thereby improving the reliability of location activation.

[0124] Please see Figure 6 , Figure 6 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by a service node. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0125] Step 601: Receive resource control information sent by the anchor node. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0126] Optionally, resource control information includes at least one of the following:

[0127] Resource activation information, wherein the resource activation information is used to activate the resources corresponding to the specified terminal device; and

[0128] Resource deactivation information, wherein the resource activation information is used to deactivate the resources corresponding to the specified terminal device.

[0129] In this disclosure, the resource control information may include resource activation information for activating resources. Anchor nodes can determine the resource activation information corresponding to a specified terminal device based on received information related to the location of that specified terminal device. They then instruct service nodes to reserve resources to be activated and to activate the resources corresponding to the specified terminal device according to the resource activation information. Thus, the specified terminal device can begin using the corresponding resources for location services, thereby avoiding location activation failures and improving location reliability.

[0130] Alternatively, the resource control information may include resource deactivation information for deactivating resources. When an anchor node determines that a specified terminal device has accessed from another network node, it can determine the resource deactivation information corresponding to that terminal device. This instructs the service node to release the resources to be deactivated and to deactivate the resources corresponding to the specified terminal device. As a result, the terminal device can stop using the activated resources for positioning, thus avoiding resource waste.

[0131] Optionally, the resource activation information in the resource control information includes at least one of the following: the identifier of the designated terminal device, the identifier of the probe reference signal SRS resource set, the SRS resource identifier, information on the spatially related resources between the SRS to be activated, the first activation time, the first activation duration, and a first indication for instructing the service node whether to send the resource control information and the RRC release message to the designated terminal device simultaneously.

[0132] The identifier for the designated terminal device can be any information that can uniquely identify the designated terminal device, such as the terminal device's serial number. The identifier for the Sound Reference Signal (SRS) resource set can be any information that can uniquely identify the designated SRS resource set, such as the SRS resource set's serial number. The identifier for the SRS resource can be any information that can uniquely identify the designated SRS resource, such as the SRS resource's serial number. The information about resources spatially related to the SRS to be activated can be any other information that has a spatial relationship with the SRS to be activated, such as the identifier of other signals spatially related to the SRS to be activated.

[0133] Optionally, the resource deactivation information in the resource control information includes at least one of the following: the identification information of the specified terminal device, the identifier of the deactivated SRS resource, the identifier of the deactivated SRS resource set, and the deactivation indication.

[0134] The deactivation instruction can be used to instruct the deactivation of resources corresponding to a specified terminal device. For a detailed explanation of the terminal device identifier, SRS resource identifier, and SRS resource set identifier, please refer to the detailed description of any embodiment of this disclosure, which will not be repeated here.

[0135] Optionally, resource control information is included in at least one of the following messages sent to the service node: a terminal device context retrieval failure message, a radio access network (RAN) paging message, an Xn interface application procedure protocol message, a terminal device context retrieval confirmation message, a location activation request message, and a location deactivation request message.

[0136] Step 602: Activate or deactivate the resources corresponding to the specified terminal device based on the resource control information.

[0137] In this disclosure, after receiving resource activation information, the service node can identify the designated terminal device based on the identifier of the designated terminal device in the resource activation information and send the resource activation information to the designated terminal device. Thus, the designated terminal device can activate the SRS resource indicated in the resource activation information at the first activation time and keep the SRS resource in an active state during the first activation duration. After the first activation duration, it can actively deactivate the SRS resource, thereby avoiding the need for additional deactivation signaling to activate the SRS resource and preventing resource waste.

[0138] Alternatively, the service node can identify the specified terminal device based on the identifier of the terminal device in the resource deactivation information and deactivate the resources of the specified terminal device. This avoids resource waste.

[0139] In this disclosure, after receiving resource control information from the anchor node for activating or deactivating resources corresponding to a specified terminal device in an RRC inactive state, the service node can activate or deactivate the resources corresponding to the specified terminal device according to the resource control information. This avoids location activation or deactivation failures, prevents resource waste, and improves location reliability.

[0140] Please see Figure 7 , Figure 7 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by a service node. Figure 7 As shown, the method may include, but is not limited to, the following steps:

[0141] Step 701: Receive resource control information sent by the anchor node. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0142] The specific implementation process of step 701 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0143] Step 702: Based on the information in the resource control information for activating the resources corresponding to the specified terminal device, send information indicating resource activation and an RRC release message to the specified terminal device.

[0144] In this disclosure, after receiving resource control information, if the resource control information contains information for activating resources corresponding to a specified terminal device, the service node can send the information indicating resource activation along with an RRC release message to the specified terminal device. Thus, the specified terminal device can use the activation instruction to perform positioning measurements, such as sending SRS resources.

[0145] Optionally, when the resource control information includes information for activating resources corresponding to a specified terminal device, the service node can send information indicating resource activation to the specified terminal device via a paging message. This information indicating resource activation may be the same as or different from the information in the resource control information used to activate resources corresponding to the specified terminal device.

[0146] Optionally, when the resource control information contains information for activating resources corresponding to a specified terminal device, the service node can send information indicating resource activation to the specified terminal device through an RRC release message.

[0147] In this disclosure, after receiving resource control information from the anchor node for activating or deactivating resources corresponding to a designated terminal device that is in an inactive state under Radio Resource Control (RRC), the serving node can send information indicating resource activation and an RRC release message to the designated terminal device based on the information contained in the resource control information for activating the resources corresponding to the designated terminal device. This avoids location activation failures and improves location reliability.

[0148] Please see Figure 8 , Figure 8 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by a service node. Figure 8 As shown, the method may include, but is not limited to, the following steps:

[0149] Step 801: Receive resource control information sent by the anchor node. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0150] The specific implementation process of step 801 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0151] Step 802: Release the resources corresponding to the specified terminal device according to the information contained in the resource control information for deactivating the resources corresponding to the specified terminal device.

[0152] In this disclosure, the anchor node can determine the specified terminal device based on the identifier of the specified terminal device in the location deactivation request sent by the LMF for the specified terminal device. Then, it can determine the resources corresponding to the specified terminal device and generate resource deactivation information corresponding to the specified terminal device to instruct the service node to release the resources corresponding to the specified terminal device to avoid resource waste.

[0153] Optionally, when a specified terminal device sends a Radio Resource Control (RRC) recovery request to access the anchor node through another network node, it indicates that the specified terminal device is not within the service range of the serving node. In this case, the resource deactivation information corresponding to the specified terminal device can be determined based on the RRC recovery request.

[0154] Optionally, when a specified terminal device sends a Radio Resource Control (RRC) connection request to access the anchor node through another network node, it indicates that the specified terminal device is not within the service range of the serving node. In this case, the resource deactivation information corresponding to the specified terminal device can be determined based on the RRC connection request.

[0155] In this disclosure, after receiving resource control information from the anchor node for activating or deactivating resources corresponding to a specified terminal device that is in an inactive state under Radio Resource Control (RRC), the serving node can release the resources corresponding to the specified terminal device based on the information contained in the resource control information for deactivating the resources corresponding to the specified terminal device. This avoids resource waste.

[0156] Please see Figure 9 , Figure 9 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by a service node. Figure 9 As shown, the method may include, but is not limited to, the following steps:

[0157] Step 901: Receive resource control information sent by the anchor node. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0158] Step 902: Activate or deactivate the resources corresponding to the specified terminal device based on the resource control information.

[0159] The specific implementation process of steps 901-902 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0160] Step 903: Send activation feedback information or deactivation feedback information to the anchor node.

[0161] The activation feedback information may include at least one of the following: a second activation time and a second activation duration. The second activation time is the SRS activation time determined by the service node, and the second activation duration is the SRS activation duration determined by the service node.

[0162] In this disclosure, when a service node receives resource activation information from an anchor node, if the resource activation information does not include time-related information, such as a first activation time and a first activation duration, then the service node can determine relevant time information for resource activation, such as a second activation time and a second activation duration. Alternatively, if the resource activation information includes time-related information, the service node can also determine, based on the actual network conditions, whether to activate the resources of the specified terminal device according to the first activation time and the first activation duration in the resource control information. If the service node determines not to activate the resources of the specified terminal device according to the first activation time and the first activation duration in the resource control information, it can determine the second activation time and the second activation duration itself. After determining the second activation time and the second activation duration, the service node can send an activation feedback message to the anchor node to synchronize the second activation time and the second activation duration. It is understood that the second activation time and the first activation time can be the same or different, and the second activation duration and the first activation duration can be the same or different.

[0163] Optionally, the service node can also send deactivation feedback information to the anchor node.

[0164] In this disclosure, when the service node receives the resource deactivation information sent by the anchor node, the service node activates the resources of the specified terminal device according to the resource control information, or it can re-determine the deactivation time according to the actual network conditions, and can send deactivation feedback information to the anchor node to synchronize the deactivation time and other information with the anchor node.

[0165] Optionally, activation feedback information or deactivation feedback information may be sent to the service node in at least one of the following messages: failure to retrieve terminal device context message, RAN paging message, Xn interface application process protocol message, retrieval of terminal device context confirmation message, location activation request message, location deactivation request message, etc.

[0166] Optionally, the service node can also execute step 903 first and then step 902. That is, after receiving the resource control message, the service node does not directly activate or deactivate the resources corresponding to the specified terminal device, but first sends activation feedback information or deactivation feedback information to the anchor node to send the second activation time and the second continuous activation time. Then, after receiving the RRC release message sent by the anchor node, it then activates or deactivates the resources corresponding to the specified terminal device.

[0167] In this disclosure, after receiving resource control information from the anchor node for activating or deactivating resources corresponding to a designated terminal device that is in an inactive state under Radio Resource Control (RRC), the serving node can activate or deactivate the resources corresponding to the designated terminal device based on the resource control information. Afterward, it can send activation feedback information or deactivation feedback information to the anchor node. Thus, by exchanging activation-related information among network nodes, location activation failures are avoided while ensuring the accuracy of location activation, thereby improving the reliability of location activation.

[0168] Please see Figure 10 , Figure 10 This is a schematic flowchart illustrating a method for activating or deactivating a resource according to an embodiment of this disclosure. This method is executed by a service node. Figure 10 As shown, the method may include, but is not limited to, the following steps:

[0169] Step 1001: Receive resource control information sent by the anchor node. The resource control information is used to activate or deactivate the resources corresponding to the specified terminal device. The specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0170] The specific implementation process of step 1001 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0171] Step 1002: Send activation feedback information or deactivation feedback information to the anchor node.

[0172] Optionally, when the specified terminal device is in an inactive RRC state, it means that the RRC is occupied. In this case, the resources corresponding to the specified terminal device can be not activated. The resources corresponding to the specified terminal device can be activated after receiving the RRC release message sent by the anchor node.

[0173] Optionally, when the resource control information contains a first indication, and the first indication instructs the service node to send the resource control information and the RRC release message to the designated terminal device at the same time, the resource corresponding to the designated terminal device shall not be activated before the RRC release message sent by the anchor node is received.

[0174] Step 1003: Activate or deactivate the resources corresponding to the specified terminal device based on the resource control information.

[0175] The specific implementation process of step 1003 in this disclosure can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0176] In this disclosure, after receiving resource control information from the anchor node for activating or deactivating resources corresponding to a designated terminal device that is in an inactive state under Radio Resource Control (RRC), the serving node temporarily suspends activation of the resources corresponding to the designated terminal device until it receives an RRC release message from the anchor node. Subsequently, it can send activation or deactivation feedback information to the anchor node. Then, based on the resource control information, it can activate or deactivate the resources corresponding to the designated terminal device. This avoids location activation or deactivation failures and improves location reliability.

[0177] The methods for activating or deactivating resources are further explained below. In this disclosure, resource activation or deactivation can be achieved through the following methods:

[0178] Method 1:

[0179] See Figure 11a The method includes the following steps:

[0180] Step 1101: The LMF sends a location activation request message to the anchor gNB.

[0181] Step 1102: The anchor gNB sends information for location activation to the serving gNB.

[0182] According to one embodiment, the information for location activation can be included in a Retrieve UE Context Failure message; according to another embodiment, the information for location activation is included in a RAN paging message. It should be understood that the message including the information for location activation is not limited to these embodiments. The information for location activation is also known as resource activation information.

[0183] The information used to locate activation may include at least one of the following:

[0184] The SRS Resource Set ID is used to indicate the SRS resource that needs to be activated.

[0185] Information related to SRS spatial relationships is used to indicate the spatial relationships corresponding to the SRS resource or SRS resourceet that needs to be activated;

[0186] Activation time, used to indicate the specific time when SRS is activated, can be an absolute time or a relative time;

[0187] Activation duration, used to indicate the duration of SRS activation.

[0188] The activation time is also the first activation time, and the activation duration is also the first activation duration.

[0189] Step 1103, serving gNB considers the information used for location activation and activates SRS.

[0190] Optionally, the serving gNB may send the MAC CE used to activate SRS along with the RRC Release message to the designated terminal device; alternatively, the serving gNB may also include the location activation information in the RRC Release message, so that the designated terminal device activates SRS based on the location activation information in the RRC Release message; or, the location activation information may be included in the paging message and sent to the designated terminal device. It should be understood that the above are merely examples, and the methods for enabling a designated terminal device to activate SRS are not limited to these.

[0191] If the information used for activation includes time information, such as activation time and / or activation duration, the specified terminal device and serving gNB can also consider activating or deactivating the corresponding SRS based on the time information. This can avoid additional deactivation signaling to deactivate the SRS.

[0192] In this invention, activation means enabling a designated terminal device to start sending SRS and / or enabling the gNB to reserve the corresponding SRS resources, while deactivation means enabling a designated terminal device to stop sending SRS and / or enabling the gNB to release the reserved corresponding SRS resources.

[0193] Step 1104: The anchor gNB sends a location activation feedback message to the LMF.

[0194] The effect achievable by the above method is as follows: if a designated terminal device in the RRC_INACTIVE state (not activated by RRC) moves to a new serving base station (i.e., to the serving gNB), while the designated terminal device context is still in the anchor gNB, this invention can support semi-static SRS activation or deactivation, avoiding location activation failure. Simultaneously, this invention also supports a time-based deactivation method, reducing the deactivation signaling process and making it more suitable for locating designated terminal devices in the RRC_INACTIVE state.

[0195] Method 2:

[0196] See Figure 11b The method includes the following steps:

[0197] Step 1105: The LMF sends a location deactivation request message to the anchor gNB.

[0198] The location deactivation request message may contain resource deactivation information, such as:

[0199] The terminal device identifier (ID) is used to identify a specific terminal device, i.e., a designated terminal device.

[0200] Deactivated SRS resource, used to indicate the SRS resource that needs to be deactivated, such as the SRS Resourceset ID;

[0201] The deactivation instruction is used to instruct the deactivation of all SRS resources of a specific terminal device.

[0202] Step 1106: The anchor gNB sends location deactivation information to the serving gNB.

[0203] Step 1107, serving gNB releases the corresponding SRS.

[0204] Step 1108: The serving gNB sends location deactivation information to the terminal device.

[0205] Among them, location deactivation information is also resource deactivation information.

[0206] Upon receiving the location deactivation information, the Serving gNB can release the corresponding SRS resources and instruct the terminal device to activate the corresponding SRS, i.e., stop sending SRS.

[0207] Step 1109: The anchor gNB sends a location deactivation feedback message to the LMF.

[0208] The effect achievable by the above method is that if a specified terminal device in the RRC_INACTIVE state (which is not activated by RRC) moves to a new serving base station (i.e., to the serving gNB), while the specified terminal device context is still in the anchor gNB, this invention can support the deactivation of semi-static SRS, thus avoiding resource waste.

[0209] Method 3:

[0210] See Figure 12 The method includes the following steps:

[0211] Step 1201: The LMF sends a location activation request message to the anchor gNB.

[0212] Step 1202: Serving gNB-CU to obtain location activation related information.

[0213] Step 1203: In the CU-DU separation architecture, the serving gNB-CU (hereinafter referred to as CU) sends a terminal device context release command message to the serving gNB-DU (hereinafter referred to as DU).

[0214] The terminal device context release command message includes information for locating activation, which may include at least one of the following:

[0215] SRS Resource Set ID, used to indicate the SRS resource that needs to be activated;

[0216] Information related to SRS spatial relationships is used to indicate the spatial relationships corresponding to the SRS resource or SRS resourceet that needs to be activated;

[0217] Activation time, used to indicate the specific time when SRS is activated, can be an absolute time or a relative time;

[0218] Activation duration, used to indicate the duration of SRS activation;

[0219] The first instruction is used to notify the DU that the MAC CE used to activate SRS needs to be sent to the designated terminal device along with the RRC Release message.

[0220] The DU receives the information for location activation and considers the information to activate SRS and / or reserve SRS resources. According to one embodiment, the DU sends the MAC CE for SRS activation along with an RRC Release message to the designated terminal device; according to another embodiment, the information for SRS activation is already included in the RRC Release message, and the DU reserves corresponding SRS resources for the designated terminal device based on the location activation information.

[0221] The effect achievable by the above method is as follows: Under the CU-DU separation architecture, if a designated terminal device in the RRC_INACTIVE state moves to a new serving base station (i.e., to the serving gNB), while the designated terminal device context is still in the anchor gNB, this invention can support semi-static SRS activation or deactivation, avoiding location activation failure. Simultaneously, this invention also supports a time-based deactivation method, reducing the deactivation signaling process and making it more suitable for locating designated terminal devices in the RRC_INACTIVE state.

[0222] Method 4:

[0223] See Figure 13 The method includes the following steps:

[0224] Step 1301: Anchor gNB obtains location deactivation information.

[0225] According to one embodiment, as in step 1301a, the LMF sends a location deactivation message to the anchor gNB, and the anchor gNB receives the location deactivation information from the LMF. According to another embodiment, as in step 1301b, the designated terminal device initiates an RRC resume or RRC setup procedure from a gNB different from the serving gNB. The anchor gNB can determine that the designated terminal device has stopped sending SRS by accessing from other cells or base stations, thus obtaining the location deactivation information. It should be understood that the above are merely examples, and the method by which the anchor gNB obtains location deactivation is not limited to these.

[0226] Among them, location deactivation information is also resource deactivation information.

[0227] Step 1302: The anchor gNB sends information to the serving gNB for deactivating the positioning.

[0228] Information used for deactivating location can be included in the XnAP message, such as a location deactivation message. This information is essentially resource control information.

[0229] The information used to deactivate the location may include at least one of the following:

[0230] The terminal device identifier (ID) is used to identify a specific terminal device, i.e., a designated terminal device.

[0231] Deactivated SRS resource, used to indicate the SRS resource that needs to be deactivated, such as the SRS Resourceset ID;

[0232] The deactivation instruction is used to instruct the deactivation of all SRS resources of a specific terminal device.

[0233] The Serving gNB considers information used to deactivate the location and releases the corresponding SRS resources.

[0234] The effect achievable by the above method is that if the specified terminal device in the RRC_INACTIVE state moves to a new serving base station, i.e., to the serving gNB, while the specified terminal device context is still in the anchor gNB, the present invention can allow the serving gNB to release SRS resources in a timely manner, thus avoiding the waste of uplink resources.

[0235] Method 5:

[0236] See Figure 14 The method includes the following steps:

[0237] Step 1401: The LMF sends a location activation request message to the anchor gNB.

[0238] Step 1402: If the specified terminal device is under the serving gNB, the anchor gNB sends a first message to the serving gNB. The first message includes request information for activating positioning. The first message can be an XnAP message, such as a Partial UE Context Transfer message or a positioning activation request message. The feedback information for activating positioning includes at least one of the following:

[0239] SRS Resource Set ID, used to indicate the SRS resource that needs to be activated;

[0240] Information related to SRS spatial relationships is used to indicate the spatial relationships corresponding to the SRS resource or SRS resourceet that needs to be activated.

[0241] The first activation time is used to indicate the specific time when the SRS requested by the LMF is activated; it can be an absolute time or a relative time.

[0242] The first activation duration is used to indicate the duration of SRS activation requested by the LMF.

[0243] The first instruction is used to notify the MAC CE of the serving gNB for activating SRS that it needs to be sent to the designated terminal device along with the RRRCrease message.

[0244] Step 1403: The serving gNB receives messages and information, and sends a second message to the anchor gNB. This second message includes feedback information for activating location. The second message can be an XnAP message, such as a Partial UE Context Transfer Acknowledgement message or a location activation feedback message. The feedback information for activating location includes at least one of the following:

[0245] The second activation time is used to indicate the SRS activation time determined by the serving gNB.

[0246] The second activation duration is used to indicate the duration of SRS activation determined by the serving gNB.

[0247] Wherein, the serving gNB does not activate the SRS corresponding to the terminal device according to the first instruction, the SRS activation time determined by the serving gNB may be different from the first activation time, and the SRS activation duration determined by the serving gNB may be different from the first activation duration.

[0248] If the activated SRS is used for a specified terminal device in the RRC INACTIVE state or the first message includes a first indication, the serving gNB will temporarily not activate the SRS until it receives an XnAP message including an RRC Release message from the anchor gNB, such as a terminal device context retrieval failure message.

[0249] The method for activating SRS in Serving gNB is the same as described in step 103, and will not be repeated here.

[0250] Step 1404: The anchor gNB sends a positioning activation feedback message to the LMF. The feedback message may include feedback information received in step 1403 for activating positioning.

[0251] LMF can take this information into account and begin sending measurement requests to the base stations participating in the positioning measurement.

[0252] In steps 1405 and 1406, the anchor gNB sends the RRC Release message to the designated terminal device via the serving gNB. The serving gNB, based on the information received in step 1402, sends the MAC CE used to activate SRS along with the RRC Release message to the designated terminal device.

[0253] The effect achievable by the above method is that if a specified terminal device in the RRC_INACTIVE state moves to a new serving base station, while the specified terminal device context is still in the anchor gNB, the present invention can support the activation or deactivation of semi-static SRS, avoiding the failure of location activation, and at the same time allowing the serving gNB to confirm whether location activation can be successful.

[0254] Method Six:

[0255] See Figure 15 The method includes the following steps:

[0256] Step 1501: The LMF sends a location activation request message to the anchor gNB.

[0257] Step 1502: If the specified terminal device is under the serving gNB, the anchor gNB sends a third message to the serving gNB, the third message including request information for activating location. The third message may be a terminal device context retrieval failure message or a new XnAP message, such as a location activation request message. The feedback information for activating location includes at least one of the following:

[0258] SRS Resource Set ID, used to indicate the SRS resource that needs to be activated;

[0259] Information related to SRS spatial relationships is used to indicate the spatial relationships corresponding to the SRS resource or SRS resourceet that needs to be activated.

[0260] The first activation time is used to indicate the specific time when the SRS requested by the LMF is activated; it can be an absolute time or a relative time.

[0261] The first activation duration is used to indicate the duration of SRS activation requested by the LMF.

[0262] The first instruction is used to notify the MAC CE of the serving gNB for activating SRS that it needs to be sent to the designated terminal device along with the RRC Release message.

[0263] In step 1503, the Serving gNB receives the message and information, and activates the SRS based on the information. The way the Serving gNB activates the SRS is the same as described in step 1103, and will not be repeated here.

[0264] Step 1504: The serving gNB sends a fourth message to the anchor gNB, the fourth message including feedback information for activating positioning. The second message is an XnAP message, such as a positioning activation feedback message. Optionally, the feedback information for activating positioning includes at least one of the following:

[0265] The second activation time is used to indicate the duration of SRS activation determined by the serving gNB.

[0266] The second activation duration is used to indicate the duration of SRS activation determined by the serving gNB.

[0267] Since the serving gNB activates the SRS corresponding to the terminal device according to the first instruction, the SRS activation time determined by the serving gNB is the first activation time, and the SRS activation duration determined by the serving gNB is the first activation duration.

[0268] Step 1505: The anchor gNB sends a positioning activation feedback message to the LMF. The feedback message may include feedback information received in step 1504 for activating positioning.

[0269] LMF can consider the information and begin sending a positioning measurement request.

[0270] The effect achievable by the above method is that if a specified terminal device in the RRC_INACTIVE state moves to a new serving base station, while the specified terminal device context is still in the anchor gNB, the present invention can support the activation or deactivation of semi-static SRS, avoiding the failure of location activation, and at the same time enabling LMF to obtain accurate activation feedback information.

[0271] Please see Figure 16 This is a schematic diagram of the structure of a communication device 1600 provided in an embodiment of this disclosure. Figure 16 The communication device 1600 shown may include a transceiver module 1601. The transceiver module 1601 may include a transmitting module and / or a receiving module. The transmitting module is used to implement the transmitting function, and the receiving module is used to implement the receiving function. The transceiver module 1601 can implement both transmitting and / or receiving functions.

[0272] It is understandable that the communication device 1600 can be an anchor node, a device within an anchor node, or a device that can be used in conjunction with an anchor node.

[0273] Communication device 1600 is located on the anchor node side, wherein:

[0274] The processing module 1602 is used to determine the resource control information corresponding to a specified terminal device, wherein the resource control information is used to activate or deactivate the resources corresponding to the specified terminal device, and the specified terminal device is a terminal device in the inactive state of Radio Resource Control (RRC).

[0275] The transceiver module 1601 is used to send the resource control information to the service node.

[0276] Optionally, the resource control information includes at least one of the following:

[0277] Resource activation information, wherein the resource activation information is used to activate the resources corresponding to the specified terminal device; and

[0278] Resource deactivation information, wherein the resource activation information is used to deactivate the resources corresponding to the specified terminal device.

[0279] Optionally, the transceiver module 1601 described above is used for:

[0281] Based on the received location deactivation request for the specified terminal device sent by the LMF node, determine the resource deactivation information corresponding to the specified terminal device; or,

[0282] Based on the Radio Resource Control (RRC) recovery request sent by the designated terminal device to other network nodes, determine the resource deactivation information corresponding to the designated terminal device; or...
