[0136] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2B .

[0137] In a first aspect, embodiments of the present disclosure provide a report transmission method. FIG3 is a schematic flow chart illustrating a report transmission method according to an embodiment of the present disclosure. The report transmission method illustrated in this embodiment can be executed by a terminal. As shown in FIG3 , the report transmission method may include the following steps:

[0138] In step S301 , it is determined according to first information whether to execute report sending when a first event occurs or is about to occur.

[0139] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0140] In some embodiments, the terminal may determine, based on the first information, whether to send a report when the first event occurs or is about to occur. Since the terminal deletes (also described as releasing or discarding) the report when it determines that the first event has occurred or is about to occur, in some scenarios, the terminal may detect that the first event has occurred or is about to occur at the terminal without sending the report to the network device. In other words, the terminal may delete the report in response to detecting that the first event has occurred or is about to occur at the terminal, resulting in a waste of resources. According to this embodiment, for example, when the terminal determines that the first event has occurred or is about to occur, the terminal may send a report, thereby ensuring that the terminal can send the report to the network device, which helps avoid waste of resources. In one example, when the terminal determines that the first event has occurred or is about to occur, the report is sent. In another example, when the terminal determines that the first event has occurred or is about to occur, the report is sent before the report is deleted.

[0141] In some embodiments, the report sending method further includes: receiving first information sent by the first network device.

[0142] In some embodiments, the first network device includes at least one of the following: access network equipment; core network equipment; operation administration and maintenance (OAM) equipment.

[0143] FIG4 is a schematic flow chart of another report sending method according to an embodiment of the present disclosure. The report sending method shown in this embodiment can be executed by a terminal. As shown in FIG4, the report sending method further includes:

[0144] In step S401, capability indication information is sent to a first network device or a second network device, wherein the capability indication information is used to indicate whether the terminal supports report sending.

[0145] It should be noted that the embodiment shown in FIG4 can be implemented independently or in combination with at least one other embodiment of the present disclosure. The specific selection can be made as needed and is not limited by the present disclosure. In addition, step S401 can be performed before step S301 as shown in FIG4, or it can be performed after step S301, or it can be performed simultaneously with step S301.

[0146] In some embodiments, a terminal may send capability indication information to a first network device, where the first network device may be a network device in a first network in which the terminal is located. The first network device may determine whether the terminal supports report sending based on the capability indication information, so that the first network device can perform appropriate subsequent operations accordingly. For example, if it is determined that the terminal supports report sending, a report request may be sent to the terminal, requesting the terminal to send a report to the first network device. For example, if it is determined that the terminal does not support report sending, it is not necessary to send a report request to the terminal, which helps conserve communication resources.

[0147] In some embodiments, a terminal may send capability indication information to a second network device, where the second network device may be a network device in the second network to which the terminal is switched from the first network. The second network device may determine whether the terminal supports report sending based on the capability indication information, so that the second network device can perform appropriate subsequent operations accordingly. For example, if it is determined that the terminal supports report sending, a report request may be sent to the terminal to request the terminal to send a report to the second network device. For example, if it is determined that the terminal does not support report sending, it is not necessary to send a report request to the terminal, which helps save communication resources.

[0148] In some embodiments, the terminal may send capability indication information in an explicit manner. For example, the terminal may carry the capability indication information in a terminal capability message. For example, a new information field may be added to the terminal capability message, or an existing information field may be used as the capability indication information. Then, a first network device or a second network device that receives the terminal capability message may determine whether the terminal supports report transmission based on the capability indication information therein.

[0149] In some embodiments, the terminal may send capability indication information in an implicit manner. For example, the terminal may send information related to report transmission to the first network device or the second network device. The information related to report transmission includes, but is not limited to, one of the following: a report, a report request, and the first information. Upon receiving the information related to report transmission, the first network device or the second network device may determine that the terminal supports report transmission.

[0150] In some embodiments, the first event includes at least one of the following:

[0151] Terminal to register;

[0152] The terminal moves out of the pre-configured area;

[0153] The duration of the measurement for which the report is being performed is greater than or equal to the first duration;

[0154] The duration of the maintenance report is greater than or equal to the second duration;

[0155] The terminal receives the new configuration of the measurement.

[0156] In some embodiments, the first event may include terminal deregistration. When the terminal deregisters or is about to deregister, the terminal may delete the report. For example, if the terminal deregisters from the first network, the terminal may delete the report obtained in the first network. However, if the terminal deletes the report before sending it to the network device in the first network, it will result in a waste of resources.

[0157] According to an embodiment of the present disclosure, the terminal may perform report sending when deregistering or about to deregister, and send the report to the network device in the first network, which is conducive to avoiding waste of resources.

[0158] In some embodiments, terminal deregistration may be triggered by network switching, which includes but is not limited to switching between SNPN (Stand-alone Non-Public Network) and PLMN (Public Land Mobile Network).

[0159] In some embodiments, the terminal deregistration includes at least one of the following: a deregistration process triggered by the terminal, and a deregistration process triggered by a network device.

[0160] For example, the deregistration process triggered by the terminal includes: the terminal notifying the network device that the terminal no longer wishes to access the first network, so that the terminal can deregister from the first network.

[0161] For example, the deregistration process triggered by the network device includes: the network device notifies the terminal that the terminal can no longer access the first network, so that the terminal can deregister from the first network.

[0162] For example, the deregistration process triggered by the network device includes: the network device notifies the terminal that the first network registered by the terminal is not allowed to operate at the location of the terminal, so that the terminal can be deregistered from the first network.

[0163] The first network includes at least one of the following: a public network and a non-public network. The public network includes but is not limited to a public land mobile network (PLMN).

[0164] Taking the deregistration process triggered by the network device as an example, the network device may explicitly instruct the terminal to deregister, or the network device may implicitly instruct the terminal to deregister.

[0165] The network device explicitly instructs the terminal to deregister, for example, by signaling such as a cause of radio resource control establishment (RRCestablishment) or a cause of radio resource control resumption (RRCresume).

[0166] The network device implicitly instructs the terminal to register, for example, through information such as network identification information, network type information, and terminal access status indication (e.g., independent non-public network access mode (SNPN access mode)). For example, the network device implicitly instructs the terminal to register through network identification information. After the terminal receives the network identification information, it can determine whether the network identification in the network identification information is within the network identifications registered by the terminal. If it is not within the registered network identifications, the terminal can determine that registration is required. For example, the terminal can deregister from the currently registered first network and register with the network corresponding to the network identification information.

[0167] In some embodiments, the first event may include the terminal moving out of a preconfigured area. For example, the terminal may store information about preconfigured areas to which the report applies, such as information about preconfigured areas including but not limited to one or more area identifiers, such as a list of area identifiers.

[0168] In some embodiments, the area identifier includes at least one of the following: a network identifier, a tracking area code (TAC), a tracking area identity (TAI), and a cell identifier.

[0169] In some embodiments, the network identifier includes at least one of the following: an identifier of a public network, an identifier of a non-public network.

[0170] In some embodiments, the non-public network includes at least one of the following: a stand-alone non-public network (SNPN), a public and non-public integrated network (Public Network Integrated NPN, PNI-NPN).

[0171] Taking the example of a public network including a PLMN, the pre-configured information may include a PLMN identifier list, including at least one PLMN identifier. The terminal determines whether the terminal is located outside the PLMN corresponding to the PLMN identifier included in the PLMN identifier list. If the terminal is located outside the PLMN corresponding to the PLMN identifier included in the PLMN identifier list, it may be determined that the terminal has moved out of the pre-configured area.

[0172] When the terminal moves out of the preconfigured area or is about to move out of the preconfigured area, the report in the terminal is no longer applicable to the network to which the terminal is located, so the terminal can delete the report. For example, if the terminal moves out of the preconfigured area, that is, moves out of the first network, then the terminal can delete the report obtained in the first network. However, if the terminal deletes the report before the report is sent to the network device in the first network, it will result in a waste of resources.

[0173] According to an embodiment of the present disclosure, the terminal may perform report sending when moving out of the preconfigured area or about to move out of the preconfigured area, and send the report to the network device in the first network, which is conducive to avoiding waste of resources.

[0174] In some embodiments, the first event may include that the duration of the terminal performing the reported measurement is greater than or equal to the first duration. When the duration of the terminal performing the reported measurement is greater than or equal to the first duration or the duration of the terminal performing the reported measurement is about to be greater than or equal to the first duration, the terminal may delete the report. For example, the first duration may be 48 hours. Of course, the first duration is not limited to 48 hours and can be adjusted as needed, and the present disclosure does not limit it. For example, when the duration of the terminal performing the reported measurement is greater than or equal to the first duration or the duration of the terminal performing the reported measurement is about to be greater than or equal to the first duration, deleting the report obtained in the first network, and the report has not yet been sent to the network device in the first network, will result in a waste of resources.

[0175] According to an embodiment of the present disclosure, the terminal can execute report sending when the duration of performing the reported measurement is greater than or equal to the first duration or the duration of performing the reported measurement is about to be greater than or equal to the first duration, and send the report to the network device in the first network, which is conducive to avoiding waste of resources.

[0176] In some embodiments, the terminal may further send the duration of performing the reported measurement, or the remaining duration of performing the reported measurement relative to the first duration, to the network device to assist the network device in determining whether to perform report retrieval.

[0177] For example, when the network device determines that the remaining time is relatively short (for example, less than the preset time), it means that the terminal will soon delete the report. It can perform report retrieval, such as sending a report request to the terminal, and the terminal can send a report to the network device based on the report request.

[0178] In some embodiments, the first event may include the duration of the terminal maintenance report being greater than or equal to the second duration. When the duration of the terminal maintenance report is greater than or equal to the second duration or the duration of the terminal maintenance report is about to be greater than or equal to the second duration, the terminal may delete the report. For example, the terminal may start the maintenance report when a timer configured for measurement (for example, when the measurement is MDT, the timer may be T330) expires or the report variable memory is full. For example, the second duration may be 48 hours. Of course, the second duration is not limited to 48 hours and may be adjusted as needed, and the present disclosure does not limit this. For example, when the duration of the maintenance report of the terminal is greater than or equal to the second duration or the duration of the maintenance report is about to be greater than or equal to the second duration, the terminal deletes the report obtained in the first network, and the report has not yet been sent to the network device in the first network, which will result in a waste of resources.

[0179] According to an embodiment of the present disclosure, the terminal can execute report sending when the duration of the maintenance report is greater than or equal to the second duration or the duration of the maintenance report is about to be greater than or equal to the second duration, and send the report to the network device in the first network, which is conducive to avoiding waste of resources.

[0180] In some embodiments, the terminal may also report the duration of the maintenance report, or the remaining duration of the maintenance report relative to the second duration, to the network device to assist the network device in determining whether to perform report retrieval.

[0181] For example, when the network device determines that the remaining time is relatively short (for example, less than the preset time), it means that the terminal will soon delete the report. It can perform report retrieval, such as sending a report request to the terminal, and the terminal can send a report to the network device based on the report request.

[0182] In some embodiments, the first event may include the terminal receiving a new measurement configuration. When the terminal receives the new measurement configuration or is about to receive the new measurement configuration, the terminal may delete the report. For example, if the terminal receives the new measurement configuration as a new measurement configuration sent by a second network, the terminal may delete the report obtained in the first network. However, if the terminal deletes the report before the report is sent to the network device in the first network, it will result in a waste of resources.

[0183] According to an embodiment of the present disclosure, the terminal may perform report sending when receiving a new measurement configuration or when the terminal is about to receive a new measurement configuration, and send the report to the network device in the first network, which is conducive to avoiding waste of resources.

[0184] In some embodiments, the first information includes at least one of the following:

[0185] The first indication information is used to indicate that a first event has occurred or is about to occur;

[0186] The second indication information is used to indicate whether to execute report sending when the first event occurs or is about to occur.

[0187] FIG5 is a schematic flow chart of another method for sending a report according to an embodiment of the present disclosure. The method for sending a report shown in this embodiment can be executed by a terminal. As shown in FIG5 , determining whether to send a report when a first event occurs or is about to occur based on first information includes:

[0188] In step S501, it is determined that a first event has occurred or is about to occur according to first information, wherein the first information includes first indication information;

[0189] In step S502 , it is determined based on implementation whether to perform report transmission when a first event occurs or is about to occur.

[0190] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0191] In some embodiments, the first information may include the first indication information but not the second indication information. In this case, the terminal may determine that the first event has occurred or is about to occur based on the first information, and whether to perform report transmission when the first event has occurred or is about to occur may be determined by the terminal based on implementation.

[0192] Take the example where the first event includes terminal deregistration.

[0193] The first indication information may be sent by a core network device (the first network device includes a core network device) to the terminal. For example, the core network device may include an AMF (Access and Mobility Management Function). The AMF may send the first indication information to the terminal. The first indication information is used to instruct the terminal to deregister or the terminal is about to deregister. For example, the AMF may carry the first indication information in a deregistration request or a deregistration acceptance message. After receiving the first information, the terminal may determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then determine whether to perform report sending when deregistering or about to deregistering based on the implementation.

[0194] It should be noted that, when the terminal determines to execute the report transmission, it may transmit at least one of the following to the network device: a report, or an indication of availability of report-related information. The report-related information may include at least one of the following: a report, or a configuration of a measurement corresponding to the report.

[0195] FIG6 is a schematic flow chart of another method for sending a report according to an embodiment of the present disclosure. The method for sending a report shown in this embodiment can be executed by a terminal. As shown in FIG6 , determining whether to send a report when a first event occurs or is about to occur based on first information includes:

[0196] In step S601, it is determined that a first event has occurred or is about to occur;

[0197] In step S602, it is determined whether to execute report sending when a first event occurs or is about to occur according to first information, wherein the first information includes second indication information.

[0198] It should be noted that the embodiment shown in FIG. 6 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0199] In some embodiments, the first information may include the second indication information but not the first indication information. In this case, the terminal may determine that the first event has occurred or is about to occur based on information other than the first information, and determine whether to perform report transmission when the first event has occurred or is about to occur based on the second information.

[0200] The second indication information can be sent by a network device (such as a base station, a core network device, OAM, etc.) to the terminal. For example, the network device can carry the second indication information in the report retrieval related indication information and send it to the terminal, wherein the report retrieval related indication information includes but is not limited to the configuration of the report corresponding to the measurement, for example, the measurement is Logged Minimization Drive Test (Logged MDT), and the configuration can be LoggedMeasurementConfiguration.

[0201] When the terminal determines that the first event has occurred or is about to occur, for example, taking the first event including the terminal receiving a new measurement configuration, when the terminal receives the new measurement configuration sent by the base station, it can be determined that the first event has occurred or is about to occur. The terminal can then determine whether to execute report transmission when the first event has occurred or is about to occur based on the second indication information in the report retrieval-related indication information.

[0202] FIG7 is a schematic flow chart of another method for sending a report according to an embodiment of the present disclosure. The method for sending a report shown in this embodiment can be executed by a terminal. As shown in FIG7 , determining whether to send a report when a first event occurs or is about to occur based on first information includes:

[0203] In step S701, it is determined that a first event has occurred or is about to occur according to first information;

[0204] In step S702, it is determined whether to execute report sending when a first event occurs or is about to occur according to first information; wherein the first information includes first indication information and second indication information.

[0205] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0206] In some embodiments, the first information may include first indication information and second indication information. In this case, the terminal may determine that the first event has occurred or is about to occur based on the first indication information, and determine whether to perform report transmission when the first event has occurred or is about to occur based on the second indication information.

[0207] Take the first event including terminal deregistration as an example. The first indication information may be sent by the core network device (the first network device includes the core network device) to the terminal. For example, the core network device may include the AMF. The AMF may send the first indication information to the terminal, where the first indication information is used to indicate that the terminal is to deregister or the terminal is to deregister. For example, the AMF may carry the first indication information in a deregistration request or a deregistration acceptance message.

[0208] The second indication information can be sent by a network device (such as a base station, a core network device, OAM, etc.) to the terminal. For example, the network device can carry the second indication information in the report retrieval related indication information and send it to the terminal, wherein the report retrieval related indication information includes but is not limited to the configuration of the report corresponding to the measurement, for example, the measurement is Logged Minimization Drive Test (Logged MDT), and the configuration can be LoggedMeasurementConfiguration.

[0209] After receiving the first information, the terminal can determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then the terminal can determine whether to execute report sending when the first event occurs or is about to occur based on the second indication information in the report retrieval related indication information.

[0210] In some embodiments, the report sending method further includes at least one of the following:

[0211] storing the first information;

[0212] The first information is sent to the second network device.

[0213] In some embodiments, after receiving the first information, the terminal may store the first information for subsequent use. For example, the terminal may store the first information internally. For example, if the measurement is MDT, the terminal may store the first information in an MDT report variable.

[0214] In some embodiments, the terminal may send the first information to a second network device, wherein the first network device and the second network device may be different network devices, for example, network devices in different networks. Accordingly, the second network device determines whether to perform report retrieval when the first event occurs or is about to occur based on the first information.

[0215] In some embodiments, sending the first information to the second network device includes: switching from the first network to the second network, and sending the first information to the second network device in the second network.

[0216] For example, when a terminal switches from a first network to a second network or reselects from a first network to a second network during mobility, the terminal may send the first information to a second network device in the second network. Accordingly, the second network device may subsequently determine whether to perform a report retrieval based on the first information when the first event occurs or is about to occur.

[0217] In some embodiments, the terminal may first determine whether the report sending has been completed. For example, if it is determined that the report sending is to be executed, but the process of the terminal sending the report to the first network device has not yet been completed, it may be determined that the report sending is not completed; for example, if it is determined that the report sending is to be executed and the process of the terminal sending the report to the first network device has been completed, it may be determined that the report sending is completed.

[0218] For example, when the report sending is not completed, the terminal can send the first information to the second network device in the second network, and the second network device can continue to perform report retrieval based on the first information, such as requesting the terminal to send part of the report that has not yet been sent to the network device to the second network device, or resend the report to the second network device so that the terminal can complete the sending of all reports.

[0219] For example, when the report is sent completely, the terminal may determine that the report has been completely sent to the first network device, and then the terminal may not send the first information to the second network device to save communication resources.

[0220] For example, when the report is sent, although the terminal can determine that the report has been completely sent to the first network device, the terminal can also send the first information (for example, the first information includes the second indication information) to the second network device, so that the second network device can determine whether to perform report retrieval when the first event occurs or is about to occur based on the first information. For example, after the terminal switches to the second network, when the first event occurs or is about to occur, the second network device can determine whether to perform report retrieval when the first event occurs or is about to occur based on the first information.

[0221] In a second aspect, an embodiment of the present disclosure proposes a report retrieval method. FIG8 is a schematic flow chart of a report retrieval method according to an embodiment of the present disclosure. The report retrieval method shown in this embodiment can be executed by a first network device. As shown in FIG8 , the report retrieval method may include the following steps:

[0222] In step S801 , it is determined based on first information whether to perform report retrieval when a first event occurs or is about to occur.

[0223] It should be noted that the embodiment shown in FIG8 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0224] In some embodiments, the first network device can determine, based on the first information, whether to perform report retrieval when the first event occurs or is about to occur. Because when the terminal determines that the first event has occurred or is about to occur, the report is deleted (which can also be described as releasing or discarding). In some scenarios, the terminal may detect that the first event has occurred or is about to occur at the terminal without sending the report to the network device. In other words, when the terminal does not send the report to the network device, it may delete the report in response to detecting that the first event has occurred or is about to occur at the terminal, resulting in a waste of resources. According to this embodiment, for example, when the first network device determines that the first event has occurred or is about to occur at the terminal, the first network device can perform report retrieval, such as sending a report request to the terminal, so that the terminal can send the report to the network device, which helps avoid wasting resources. In one example, the report retrieval is performed when the first network device determines that the first event has occurred or is about to occur. In another example, the report retrieval is performed when the network device determines that the first event has occurred or is about to occur and before the terminal deletes the report.

[0225] In some embodiments, the report retrieval method further comprises at least one of the following:

[0226] The receiving terminal sends first information;

[0227] First information sent by a core network device or an operation, maintenance and management (OAM) device is received.

[0228] In some embodiments, the first network device includes at least one of the following: access network equipment; core network equipment; operation, maintenance and management equipment.

[0229] For example, the first network device includes an access network device, and the access network device may receive the first information from the terminal, or may receive the first information from a core network device, or may receive the first information from an OAM.

[0230] For example, the first network device includes a core network device, and the core network device may receive the first information from the terminal, or may receive the first information from an access network device, or may receive the first information from an OAM.

[0231] For example, the first network device includes an OAM, and the OAM may receive the first information from the terminal, or may receive the first information from an access network device, or may receive the first information from a core network device.

[0232] In some embodiments, the first information includes first indication information and second indication information, and the first network device may receive the first indication information and the second indication information from different devices.

[0233] For example, the first network device is an access network device. For example, the access network device may receive first indication information from a terminal and second indication information from another access network device, a core network device, or an operation, maintenance, and management device. For example, the access network device may receive first indication information from another access network device, a core network device, or an operation, maintenance, and management device and second indication information from a terminal.

[0234] For example, the first network device is a core network device. For example, the core network device may receive first indication information from a terminal and second indication information from an access network device, another core network device, or an operation, maintenance, and management device. For example, the core network device may receive first indication information from an access network device, another core network device, or an operation, maintenance, and management device and second indication information from a terminal.

[0235] For example, the first network device is an operation, maintenance, and management device. For example, the operation, maintenance, and management device can receive first indication information from a terminal and second indication information from an access network device or a core network device. For example, the operation, maintenance, and management device can receive first indication information from an access network device or a core network device and second indication information from a terminal.

[0236] In some embodiments, the report retrieval method further includes: sending capability indication information to the terminal, wherein the capability indication information is used to indicate whether the first network device supports report retrieval.

[0237] In some embodiments, a first network device may send capability indication information to a terminal, where the first network device may be a network device in a first network where the terminal is located. The terminal may determine whether the first network device supports report retrieval based on the capability indication information, so that the terminal can perform appropriate subsequent operations accordingly. For example, if it is determined that the first network device supports report retrieval, the terminal may wait for receiving a report request from the first network device before sending a report to the first network device; for example, if it is determined that the first network device does not support report sending, the terminal may not wait for the report request from the first network device, but may instead autonomously send a report to the first network device, so that the report is sent to the first network device in a timely manner.

[0238] In some embodiments, the first network device may send the capability indication information in an explicit manner or in an implicit manner.

[0239] Taking the example of the first network device implicitly sending capability indication information to the terminal, in some embodiments, the report retrieval method further includes: sending a report request to the terminal. For example, the report request is used to implicitly indicate that the first network device supports report retrieval.

[0240] That is, in some embodiments, the first network device may send a newly defined report request to the terminal. This newly defined report request may both request the terminal to send a report and implicitly indicate that the first network device supports report retrieval. Based on this newly defined report request, the terminal may send a report to the network device and may also determine that the first network device supports report retrieval.

[0241] Taking the example of the first network device sending capability indication information to the terminal in an explicit manner, the network device may carry the capability indication information in radio resource control RRC signaling, and explicitly indicate whether the first network device supports report retrieval through the capability indication information.

[0242] In some embodiments, the first event includes at least one of the following:

[0243] Terminal to register;

[0244] The terminal moves out of the pre-configured area;

[0245] The duration of the measurement for which the report is being performed is greater than or equal to the first duration;

[0246] The duration of the maintenance report is greater than or equal to the second duration;

[0247] The terminal receives the new configuration of the measurement.

[0248] In some embodiments, the first event may include terminal deregistration. When the first network device determines that the terminal has deregistered or is about to deregister, the terminal may delete the report. For example, if the first network device determines that the terminal deregisters from the first network, the terminal may delete the report obtained in the first network. However, if the terminal deletes the report before the report is sent to the network device in the first network, it will result in a waste of resources.

[0249] According to an embodiment of the present disclosure, the first network device may perform report retrieval when the terminal deregisters or is about to deregister, for example, sending a report request to the terminal, and the terminal may send the report to the first network device, which is conducive to avoiding waste of resources.

[0250] In some embodiments, terminal deregistration may be triggered by network switching, where the network switching includes but is not limited to switching between SNPN and PLMN.

[0251] In some embodiments, the terminal deregistration includes at least one of the following: a deregistration process triggered by the terminal, and a deregistration process triggered by a network device.

[0252] For example, the deregistration process triggered by the terminal includes: the terminal notifying the network device that the terminal no longer wishes to access the first network, so that the terminal can deregister from the first network.

[0253] For example, the deregistration process triggered by the network device includes: the network device notifies the terminal that the terminal can no longer access the first network, so that the terminal can deregister from the first network.

[0254] For example, the deregistration process triggered by the network device includes: the network device notifies the terminal that the first network registered by the terminal is not allowed to operate at the location of the terminal, so that the terminal can be deregistered from the first network.

[0255] The first network includes at least one of the following: a public network and a non-public network. The public network includes but is not limited to a public land mobile network (PLMN).

[0256] Taking the deregistration process triggered by the network device as an example, the network device may explicitly instruct the terminal to deregister, or the network device may implicitly instruct the terminal to deregister.

[0257] The network device explicitly instructs the terminal to deregister, for example, by signaling such as a cause of radio resource control establishment (RRCestablishment) or a cause of radio resource control resumption (RRCresume).

[0258] The network device implicitly instructs the terminal to register, for example, through information such as network identification information, network type information, and terminal access status indication (e.g., independent non-public network access mode (SNPN access mode)). For example, the network device implicitly instructs the terminal to register through network identification information. After the terminal receives the network identification information, it can determine whether the network identification in the network identification information is within the network identifications registered by the terminal. If it is not within the registered network identifications, the terminal can determine that registration is required. For example, the terminal can deregister from the currently registered first network and register with the network corresponding to the network identification information.

[0259] In some embodiments, the first event may include the terminal moving out of a preconfigured area. For example, the first network device may store information about preconfigured areas to which the report applies, such as information about preconfigured areas including but not limited to one or more area identifiers, such as a list of area identifiers.

[0260] In some embodiments, the area identifier includes at least one of the following: a network identifier, a tracking area code (TAC), a tracking area identifier (TAI), and a cell identifier.

[0261] In some embodiments, the network identifier includes at least one of the following: an identifier of a public network, an identifier of a non-public network.

[0262] In some embodiments, the non-public network includes at least one of: a stand-alone non-public network (SNPN), a public and non-public integrated network (PNI-NPN).

[0263] Taking the example of a public network including a PLMN, the pre-configuration information may include a PLMN identifier list, including at least one PLMN identifier. The first network device determines whether the terminal is located outside the PLMN corresponding to the PLMN identifier included in the PLMN identifier list. If it is determined that the terminal is located outside the PLMN corresponding to the PLMN identifier included in the PLMN identifier list, it may be determined that the terminal has moved out of the pre-configuration area.

[0264] When the terminal moves out of the preconfigured area or is about to move out of the preconfigured area, the report in the terminal is no longer applicable to the network to which the terminal is located, so the terminal can delete the report. For example, if the terminal moves out of the preconfigured area, that is, moves out of the first network, then the terminal can delete the report obtained in the first network. However, if the terminal deletes the report before the report is sent to the network device in the first network, it will result in a waste of resources.

[0265] According to an embodiment of the present disclosure, the first network device can perform report retrieval when the terminal moves out of the preconfigured area or is about to move out of the preconfigured area, such as sending a report request to the terminal, and the terminal can send the report to the first network device, which is conducive to avoiding waste of resources.

[0266] In some embodiments, the first event may include that the duration of the terminal performing the reported measurement is greater than or equal to the first duration. When the duration of the terminal performing the reported measurement is greater than or equal to the first duration or the duration of the terminal performing the reported measurement is about to be greater than or equal to the first duration, the terminal may delete the report. For example, the first duration may be 48 hours. Of course, the first duration is not limited to 48 hours and can be adjusted as needed, and the present disclosure does not limit it. For example, when the duration of the terminal performing the reported measurement is greater than or equal to the first duration or the duration of the terminal performing the reported measurement is about to be greater than or equal to the first duration, deleting the report obtained in the first network, and the report has not yet been sent to the network device in the first network, will result in a waste of resources.

[0267] According to an embodiment of the present disclosure, the first network device can perform report retrieval when the duration of the terminal performing the reported measurement is greater than or equal to the first duration or the duration of the report measurement is about to be greater than or equal to the first duration, for example, sending a report request to the terminal, and the terminal can send the report to the first network device, which is conducive to avoiding waste of resources.

[0268] In some embodiments, the terminal may further send the duration of performing the reported measurement, or the remaining duration of performing the reported measurement relative to the first duration, to the network device to assist the network device in determining whether to perform report retrieval.

[0269] For example, when the network device determines that the remaining time is relatively short (for example, less than the preset time), it means that the terminal will soon delete the report. It can perform report retrieval, such as sending a report request to the terminal, and the terminal can send a report to the network device based on the report request.

[0270] In some embodiments, the first event may include the duration of the terminal maintenance report being greater than or equal to the second duration. When the duration of the terminal maintenance report is greater than or equal to the second duration or the duration of the terminal maintenance report is about to be greater than or equal to the second duration, the terminal may delete the report. For example, the terminal may start the maintenance report when a timer configured for measurement (for example, when the measurement is MDT, the timer may be T330) expires or the report variable memory is full. For example, the second duration may be 48 hours. Of course, the second duration is not limited to 48 hours and may be adjusted as needed, and the present disclosure does not limit this. For example, when the duration of the maintenance report of the terminal is greater than or equal to the second duration or the duration of the maintenance report is about to be greater than or equal to the second duration, the terminal deletes the report obtained in the first network, and the report has not yet been sent to the network device in the first network, which will result in a waste of resources.

[0271] According to an embodiment of the present disclosure, the first network device can perform report retrieval when the duration of the terminal maintenance report is greater than or equal to the second duration or the duration of the maintenance report is about to be greater than or equal to the second duration, such as sending a report request to the terminal. The terminal can send the report to the first network device, which is conducive to avoiding waste of resources.

[0272] In some embodiments, the terminal may also report the duration of the maintenance report, or the remaining duration of the maintenance report relative to the second duration, to the network device to assist the network device in determining whether to perform report retrieval.

[0273] For example, when the network device determines that the remaining time is relatively short (for example, less than the preset time), it means that the terminal will soon delete the report. It can perform report retrieval, such as sending a report request to the terminal, and the terminal can send a report to the network device based on the report request.

[0274] In some embodiments, the first event may include the terminal receiving a new measurement configuration. When the terminal receives the new measurement configuration or is about to receive the new measurement configuration, the terminal may delete the report. For example, if the terminal receives the new measurement configuration as a new measurement configuration sent by a second network, the terminal may delete the report obtained in the first network. However, if the terminal deletes the report before the report is sent to the network device in the first network, it will result in a waste of resources.

[0275] According to an embodiment of the present disclosure, the first network device can perform report retrieval when the terminal receives a new measurement configuration or the terminal is about to receive a new measurement configuration, such as sending a report request to the terminal. The terminal can send the report to the first network device, which is conducive to avoiding waste of resources.

[0276] In some embodiments, the first information includes at least one of the following:

[0277] The first indication information is used to indicate that a first event has occurred or is about to occur;

[0278] The second indication information is used to indicate whether to execute report retrieval when the first event occurs or is about to occur.

[0279] In some embodiments, determining whether to perform report retrieval when a first event occurs or is about to occur based on first information includes: determining whether a first event occurs or is about to occur based on the first information, wherein the first information includes first indication information; and determining whether to perform report sending when the first event occurs or is about to occur based on implementation.

[0280] In some embodiments, the first information may include the first indication information but not the second indication information. In this case, the first network device may determine that the first event has occurred or is about to occur based on the first information, and whether to perform a report transmission when the first event has occurred or is about to occur may be determined based on implementation.

[0281] Take as an example that the first network device includes a base station and the first event includes terminal deregistration.

[0282] The first indication information may be sent by the terminal to the base station. For example, the terminal may carry the first indication information in a random access message (e.g., Msg5). The first indication information is used to indicate that the terminal is deregistering or is about to deregister. After receiving the first information, the base station may determine, based on the first indication information in the first information, that the first event has occurred or is about to occur, and may further determine, based on implementation, whether to perform report retrieval when the terminal is deregistering or is about to deregister.

[0283] The first indication information may also be sent by the core network device to the base station. For example, the core network device may include an AMF. The AMF may send the first indication information to the base station. The first indication information is used to indicate that the terminal is to deregister or the terminal is to deregister. For example, the AMF may carry the first indication information in the deregistration acceptance message (for example, a new information element (IE) is added to the deregistration acceptance message to carry the first indication information), or the AMF may carry the first indication information in the non-access stratum (NAS) reason of the terminal context release request. After receiving the first information, the base station may determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then determine whether to perform report retrieval when the terminal is to deregister or the terminal is about to deregister based on the implementation.

[0284] It should be noted that, when the first network device includes a base station and the first event includes terminal deregistration, the base station may not release the terminal immediately when determining that the terminal is deregistering or is about to deregister, but may first determine based on implementation whether to perform report retrieval when the terminal is deregistering or is about to deregister. When it is determined based on implementation that report retrieval is to be performed when the terminal is deregistering or is about to deregister, since the terminal is not released, report retrieval may be performed, for example, requesting the terminal to send a report to the base station; when it is determined based on implementation that report retrieval is not to be performed when the terminal is deregistering or is about to deregister, it may be determined that the first event has occurred or is about to occur based on the first indication information in the first information, and the terminal may be released. Further optionally, when the base station determines that the report retrieval is complete, the base station may release the terminal.

[0285] Take the example where the first network device includes a core network device and the first event includes terminal deregistration.

[0286] The first indication information may be sent by the terminal to the core network device. For example, the terminal may carry the first indication information in the non-access stratum (NAS). The first indication information is used to instruct the terminal to register or the terminal is about to register.

[0287] The first indication information can also be sent by the base station or OAM to the core network device. For example, the core network device may include AMF. The base station or OAM can send the first indication information to the AMF. The first indication information is used to instruct the terminal to register or the terminal is about to register.

[0288] After receiving the first information, the core network device can determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then determine whether to perform report retrieval when the terminal deregisters or is about to deregister based on the implementation.

[0289] Take the example where the first network device includes OAM and the first event includes terminal deregistration.

[0290] The first indication information may be sent by the terminal to the OAM, and the first indication information is used to instruct the terminal to register or the terminal is about to register.

[0291] The first indication information may also be sent by the base station or the core network device to the OAM, and the first indication information is used to instruct the terminal to register or the terminal is about to register.

[0292] After receiving the first information, the OAM may determine that a first event has occurred or is about to occur according to the first indication information in the first information, and may further determine whether to perform report retrieval when the terminal is deregistering or about to deregister based on implementation.

[0293] In some embodiments, determining whether to perform report retrieval when a first event occurs or is about to occur based on first information includes: determining that a first event occurs or is about to occur; determining whether to perform report sending when the first event occurs or is about to occur based on the first information, wherein the first information includes second indication information.

[0294] In some embodiments, the first information may include the second indication information but not the first indication information. In this case, the first network device may determine that the first event has occurred or is about to occur based on information other than the first information, and determine whether to send a report when the first event has occurred or is about to occur based on the second information.

[0295] Take the example that the first network device includes a base station.

[0296] The second indication information can be sent by the AMF or OAM to the base station. For example, the AMF or OAM can carry the second indication information in the report retrieval related indication information and send it to the base station, wherein the report retrieval related indication information includes but is not limited to the configuration of the report corresponding measurement, for example, the measurement is Logged Minimization Drive Test (Logged MDT), and the configuration can be LoggedMeasurementConfiguration.

[0297] When the base station determines that a first event has occurred or is about to occur, for example, taking the first event as including the terminal receiving a new measurement configuration, the base station can determine that the first event has occurred or is about to occur when sending the new measurement configuration to the terminal. Furthermore, the base station can determine whether to perform report retrieval when the first event has occurred or is about to occur based on the second indication information in the report retrieval-related indication information.

[0298] Take the example where the first network device includes a core network device.

[0299] The second indication information can be sent by the base station or OAM to the core network device. For example, the core network device may include AMF. The base station or OAM can send the second indication information to the AMF. The second indication information is used to indicate whether to perform report retrieval when the first event occurs or is about to occur.

[0300] When the core network device determines that a first event has occurred or is about to occur, for example, taking the first event as including the terminal receiving a new measurement configuration, the core network device may determine that the first event has occurred or is about to occur. Furthermore, the core network device may determine, based on the second indication information, whether to perform a report retrieval when the first event has occurred or is about to occur.

[0301] Take the example that the first network device includes OAM.

[0302] The second indication information may be sent by the base station or the core network device to the OAM, and the second indication information is used to indicate whether to perform report retrieval when the first event occurs or is about to occur.

[0303] When OAM determines that a first event has occurred or is about to occur, for example, taking the first event as including the terminal receiving a new measurement configuration, when OAM determines that the terminal has received the new measurement configuration, it can be determined that the first event has occurred or is about to occur. Furthermore, OAM can determine, based on the second indication information, whether to perform report retrieval when the first event has occurred or is about to occur.

[0304] In some embodiments, determining whether to perform report retrieval when a first event occurs or is about to occur based on first information includes: determining that a first event occurs or is about to occur based on the first information; determining whether to perform report sending when the first event occurs or is about to occur based on the first information; wherein the first information includes first indication information and second indication information.

[0305] In some embodiments, the first information may include first indication information and second indication information. In this case, the first network device may determine that the first event has occurred or is about to occur based on the first indication information, and determine whether to perform report transmission when the first event has occurred or is about to occur based on the second indication information.

[0306] Take as an example that the first network device includes a base station and the first event includes terminal deregistration.

[0307] The first indication information may be sent by the terminal to the base station. For example, the terminal may carry the first indication information in a random access message (eg, Msg5). The first indication information is used to instruct the terminal to deregister or the terminal is about to deregister.

[0308] The first indication information may also be sent by a core network device (for example, the second network device is a core network device) to the base station. For example, the core network device may include an AMF. The AMF may send the first indication information to the base station. The first indication information is used to indicate that the terminal is to deregister or that the terminal is to deregister. For example, the AMF may carry the first indication information in a deregistration accept message (for example, a new information element is added to the deregistration accept message to carry the first indication information), or the AMF may carry the first indication information in a non-access stratum (NAS) reason of the terminal context release request.

[0309] The second indication information can be sent by the AMF or OAM (for example, the second network device includes the AMF or OAM) to the base station. For example, the AMF or OAM can carry the second indication information in the report retrieval related indication information and send it to the base station, wherein the report retrieval related indication information includes but is not limited to the configuration of the report corresponding to the measurement, for example, the measurement is a log minimized drive test (Logged MDT), and the configuration can be LoggedMeasurementConfiguration.

[0310] After receiving the first information, the base station can determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then the base station can determine whether to perform report retrieval when the first event occurs or is about to occur based on the second indication information in the report retrieval related indication information.

[0311] Take the example where the first network device includes a core network device and the first event includes terminal deregistration.

[0312] The first indication information may be sent by the terminal to the core network device. For example, the terminal may carry the first indication information in the non-access layer. The first indication information is used to instruct the terminal to register or the terminal is about to register.

[0313] The first indication information can also be sent by the base station or OAM to the core network device. For example, the core network device may include AMF. The base station or OAM can send the first indication information to the AMF. The first indication information is used to instruct the terminal to register or the terminal is about to register.

[0314] The second indication information can be sent by the base station or OAM to the core network device. For example, the core network device may include AMF. The base station or OAM can send the second indication information to the AMF. The second indication information is used to indicate whether to perform report retrieval when the first event occurs or is about to occur.

[0315] After the core network device receives the first information, it can determine that the first event has occurred or is about to occur based on the first indication information in the first information, and then the core network device can determine whether to perform report retrieval when the first event occurs or is about to occur based on the second indication information in the report retrieval related indication information.

[0316] Take the example where the first network device includes OAM and the first event includes terminal deregistration.

[0317] The first indication information may be sent by the terminal to the OAM, and the first indication information is used to instruct the terminal to register or the terminal is about to register.

[0318] The first indication information may also be sent by the base station or the core network device to the OAM, and the first indication information is used to instruct the terminal to register or the terminal is about to register.

[0319] The second indication information may be sent by the base station or the core network device to the OAM, and the second indication information is used to indicate whether to perform report retrieval when the first event occurs or is about to occur.

[0320] After receiving the first information, OAM can determine that a first event has occurred or is about to occur based on the first indication information in the first information, and then OAM can determine whether to perform report retrieval when the first event occurs or is about to occur based on the second indication information in the report retrieval related indication information.

[0321] In some embodiments, the report retrieval method further comprises at least one of the following:

[0322] storing the first information;

[0323] The first information is sent to the second network device.

[0324] In some embodiments, after receiving the first information, the first network device may store the first information for subsequent use. For example, the terminal may store the first information in the context of the terminal.

[0325] In some embodiments, a first network device may send first information to a second network device, wherein the first network device and the second network device may be different network devices, for example, network devices in different networks. Accordingly, the second network device determines whether to perform report retrieval when a first event occurs or is about to occur based on the first information.

[0326] In some embodiments, sending the first information to the second network device includes: sending the first information to the second network device in the second network to which the terminal switches from the first network.

[0327] For example, during a terminal's mobility, such as when the terminal switches from a first network to a second network, or reselects from a first network to a second network, the first network device may send the first information to the second network device in the second network. Accordingly, the second network device may subsequently determine whether to perform a report retrieval based on the first information when the first event occurs or is about to occur.

[0328] In some embodiments, the first network device may first determine whether the report retrieval has been completed. For example, if it is determined that report sending is to be executed, but the process of the terminal sending the report to the first network device has not yet been completed, the report retrieval may be determined to be incomplete; for example, if it is determined that report retrieval is to be executed and the process of the terminal sending the report to the first network device has been completed, the report retrieval may be determined to be complete.

[0329] For example, when the report retrieval is not completed, the first network device can send the first information to the second network device in the second network, and the second network device can continue to perform report retrieval based on the first information, such as requesting the terminal to send part of the report that has not yet been sent to the network device to the second network device, or resend the report to the second network device so that the terminal can complete the sending of all reports.

[0330] For example, when the report sending is completed, the first network device may determine that the terminal has completely sent the report to the first network device, and then may not send the first information to the second network device to save communication resources.

[0331] For example, when the report is sent, although the first network device can determine that the terminal has completely sent the report to the first network device, the first network device can also send the first information (for example, the first information includes the second indication information) to the second network device, so that the second network device can determine whether to perform report retrieval when the first event occurs or is about to occur based on the first information. For example, after the terminal switches to the second network, when the first event occurs or is about to occur, the second network device can determine whether to perform report retrieval when the first event occurs or is about to occur based on the first information.

[0332] In some embodiments, the present disclosure further provides a report retrieval method. The report retrieval method shown in this embodiment can be performed by the second network device. For example, the report retrieval method may include the following steps:

[0333] receiving first information sent by a terminal or a first network device;

[0334] It is determined based on the first information whether to perform report retrieval when a first event occurs or is about to occur.

[0335] In some embodiments, the terminal or the first network device may send the first information to the second network device. Since the first information can be used to determine whether to perform a report retrieval when the first event occurs or is about to occur, the second network device can also determine whether to perform a report retrieval when the first event occurs or is about to occur based on the first information.

[0336] For example, during movement, the terminal switches from a first network to a second network, or reselects from a first network to a second network, and may send the first information to a second network device in the second network.

[0337] For example, during terminal movement, such as the terminal switching from the first network to the second network, or reselecting from the first network to the second network, the first network device in the first network may send the first information to the second network device in the second network.

[0338] In some embodiments, the first information includes at least one of the following:

[0339] The first indication information is used to indicate that a first event has occurred or is about to occur;

[0340] The second indication information is used to indicate whether to execute report retrieval when the first event occurs or is about to occur.

[0341] For example, the first information may include the first indication information but not the second indication information. In this case, the second network device may determine that the first event has occurred or is about to occur based on the first information, and whether to perform report retrieval when the first event has occurred or is about to occur may be determined based on implementation.

[0342] For example, the first information may include the second indication information but not the first indication information. In this case, the second network device may determine that the first event has occurred or is about to occur based on information other than the first information, and determine whether to perform report retrieval when the first event has occurred or is about to occur based on the second information.

[0343] For example, the first information may include first indication information and second indication information. In this case, the second network device may determine that the first event has occurred or is about to occur based on the first information, and determine whether to perform report retrieval when the first event has occurred or is about to occur based on the second information.

[0344] In some embodiments, the first event includes at least one of the following: the terminal deregisters; the terminal moves out of a preconfigured area; the duration of the reported measurement is greater than or equal to a first duration; the duration of the maintenance report is greater than or equal to a second duration; or the terminal receives a new measurement configuration. For specific embodiments of each of the first events, the second network device handles the event in a similar manner to the first network device. For details, refer to the relevant embodiments described above and are not further described here.
