[0030] Figure 1 FIG. is a schematic flowchart of an access mode reporting method shown according to an embodiment of the present disclosure. The access mode reporting method shown in this embodiment can be executed by a terminal, and the terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, Internet of Things devices, etc. The terminal can communicate with a network device, and the network device includes, but is not limited to, network devices in communication systems such as 4G, 5G, 6G, etc., such as base stations, core networks, etc.

[0031] As Figure 1 shown, the access mode reporting method may include the following steps:

[0032] In step S101, report the access mode of the terminal to the network device.

[0033] According to an embodiment of the present disclosure, the terminal can report the access mode (e.g., the access mode of the terminal in the currently camped cell) to the network device, so that the network device can learn the access mode of the terminal, so that when the terminal fails to find a cell to camp on, the network device can accurately determine whether it is due to the access mode of the terminal that the terminal fails to find a cell to camp on, or due to a problem with the network coverage at the current location of the terminal that the terminal fails to find a cell to camp on.

[0034] It should be noted that after learning the access mode of the terminal, the network device can perform operations as needed, not limited to the above determination of the reason why the terminal fails to find a cell to camp on.

[0035] In one embodiment, the access mode may be an access mode that can affect the determination of acceptable cells and / or suitable cells by the terminal during cell selection and cell reselection. For example, a cell that is not applicable to the access mode will not be determined as an acceptable cell and / or a suitable cell. Among them, the access mode includes at least one of the following:

[0036] Stand-alone Non-Public Network (SNPN) access mode;

[0037] Cell Access Group (CAG)-only access mode, where when the terminal reports the CAG-only access mode, it can also report a list of allowed CAG cell identifiers (allowed CAGID list);

[0038] Public-Non-Public Integrated Network (PNI-NPN) access mode;

[0039] Public Land Mobile Network (PLMN) access mode.

[0040] When the access mode of the terminal is the SNPN access mode, the terminal can only select and register with the SNPN. The SNPN does not depend on the network functions of the PLMN, so the terminal does not support switching between the SNPN and the PLMN.

[0041] When the access mode of the terminal is the PNI-NPN access mode, the terminal can (instead of only) access the CAG. The CAG, translated as a closed access group, refers to a group composed of one or more cells that only allow terminals subscribed to the CAG to access. Among them, when the terminal subscribes to the CAG, two pieces of information can be configured in the subscription information. One is the list of CAGs supported by the terminal (such as the allowed CAG ID list), and the other is the identifier indicating whether the terminal can only access the network through CAG cells (CAG-only indication). The terminal configured with this identifier can only access the network through CAG cells.

[0042] Among them, the access mode of the terminal configured with the CAG-only indication is the CAG-only access mode, and the terminal can only select a CAG cell from the allowed CAG ID list to access the network.

[0043] The PNI-NPN depends on the network functions of the PLMN. Therefore, for terminals not configured with the CAG-only indication, switching between the PNI-NPN and the PLMN is supported.

[0044] When the access mode of the terminal is the PLMN mode, the terminal can (instead of only) access the PLMN.

[0045] In one embodiment, after learning the access mode of the terminal, if the network device determines that the terminal fails to find a cell to camp on, it can determine whether the terminal can access the cell at the terminal's current location based on the current access mode. If the terminal can access the cell at the current location, it can be determined that the reason for the terminal's failure to find a cell to camp on is the network coverage problem at the terminal's current location. If the terminal cannot access the cell at the current location, it can be determined that the reason for the terminal's failure to find a cell to camp on is the terminal's current access mode.

[0046] For example, if the access mode of the terminal is the CAG-only access mode and the cell covering the terminal's current location does not belong to the allowed CAG ID list, the terminal will fail to find a cell to camp on. In this case, since the network device can determine that the access mode of the terminal is the CAG-only access mode and can determine that the cell at the terminal's current location does not belong to the allowed CAG ID list of the terminal, it can be determined that the reason for the terminal's failure to find a cell to camp on lies in the access mode of the terminal. If the access mode of the terminal is the CAG-only access mode and the cell at the terminal's current location belongs to the allowed CAG ID list of the terminal, then for the situation where the terminal fails to find a cell to camp on, the network device can determine that the reason for the terminal's failure to find a cell to camp on is the problem with the cell covering the terminal's current location.

[0047] It should be noted that the terminal's search for a cell to camp on can be carried out in the connected state or in the idle state. For example, the terminal searches for a cell to camp on during the process of cell selection or cell reselection. Among them, the cells searched for include at least one of the following two types:

[0048] Acceptable cell, Suitable cell. The definitions of these two types of cells can refer to the limitations in related technologies, and will not be elaborated in this disclosure.

[0049] In one embodiment, the reporting of the access mode of the terminal to the network device includes:

[0050] Reporting the access mode of the terminal to the network device through implicit indication; and / or

[0051] Reporting the access mode of the terminal to the network device through explicit indication.

[0052] The way for the terminal to report the access mode of the terminal to the network device can be through implicit indication or through explicit indication. The following provides exemplary descriptions of the two ways of explicit indication and implicit indication through several embodiments.

[0053] Figure 2It is a schematic flowchart of another access mode reporting method shown according to an embodiment of the present disclosure. As Figure 2 shown, reporting the access mode of the terminal to the network device through implicit indication includes:

[0054] In step S201, report the cell information of the first cell where the terminal camps to the network device, where the cell information is used to determine the access mode of the terminal.

[0055] In one embodiment, when the terminal camps in the first cell, cell selection or cell reselection can be performed, and during this process, a second cell can be found to camp. Among them, the terminal can report the cell information of the first cell to the network device so that the network device can determine the state of the first cell based on the cell information of the first cell and then make appropriate configurations.

[0056] During this process, the terminal can indicate the access mode of the terminal through the cell information, so that the network device can determine the access mode of the terminal according to the cell information. Accordingly, there is no need to separately send indication information (separate uplink information or partial fields / information elements in the uplink information) to indicate the access mode of the terminal, which is beneficial to saving communication resources.

[0057] In one embodiment, the cell information includes at least one of the following:

[0058] PLMN identifier;

[0059] PNI-NPN identifier, used to determine that the access mode includes the PNI-NPN access mode;

[0060] Network Identifier (NID);

[0061] CAG identifier;

[0062] SNPN identifier, used to indicate that the access mode includes the SNPN access mode.

[0063] In one embodiment, since when the terminal camps in the first cell, the access mode of the terminal is applicable to the first cell, there is an association relationship between the information of the first cell and the access mode when the terminal camps in the first cell. Therefore, the access mode when the terminal camps in the first cell can be indicated by reporting the information of the first cell.

[0064] For example, when the access mode of the terminal is the SNPN access mode, then the first cell where the terminal camps belongs to SNPN, and the cell information of the first cell contains the SNPN identifier. Therefore, by reporting the SNPN identifier, the network device can be notified that the access mode of the terminal is the SNPN access mode.

[0065] Similarly, by reporting the PNI-NPN identifier, the terminal can notify the network device that the access mode of the terminal is the PNI-NPN access mode; by reporting the PLMN identifier and the CAG identifier, the terminal can also notify the network device that the access mode of the terminal is the PNI-NPN access mode; by reporting the PLMN identifier and the NID identifier, the terminal can also notify that the access mode of the terminal is the SNPN access mode.

[0066] Figure 3 is a schematic flowchart of another access mode reporting method shown according to an embodiment of the present disclosure. As Figure 3 shown, reporting the access mode of the terminal to the network device through explicit indication includes:

[0067] In step S301, a CAG-only indication is sent to the network device, where the CAG-only indication is used to indicate that the terminal is in the CAG-only access mode.

[0068] In one embodiment, when the access mode of the terminal is the CAG-only access mode, since it is difficult to indicate the CAG-only access mode through cell information, the access mode of the terminal can be indicated by means of explicit indication. For example, by sending a CAG-only indication to the network device, the network device is notified that the access mode of the terminal is the CAG-only access mode.

[0069] According to the above embodiments related to explicit indication and implicit indication, when the access mode of the terminal is the SNPN access mode, or the PLMN access mode, or the PNI-NPN access mode, the terminal can choose to report the access mode of the terminal in an implicit indication manner (such as reporting through cell information), or report the access mode of the terminal in an explicit indication manner (such as when there is no recorded cell information, reporting in an explicit indication manner).

[0070] When the access mode of the terminal is the CAG-only access mode, the terminal cannot indicate the CAG-only access mode through cell information. Therefore, regardless of whether the terminal reports cell information or not, it is necessary to send a CAG-only indication to the network device to indicate that the access mode of the terminal is the CAG-only access mode. And on the basis of reporting the CAG-only indication, an allowed CAG ID list can also be reported.

[0071] In one embodiment, the access mode is carried in at least one of the following:

[0072] UE Information Response message;

[0073] UE Assistance Information

[0074] Radio Resource Control (RRC) Reestablishment Complete Information

[0075] Radio Resource Control (RRC) Resume Complete Information

[0076] Radio Resource Control (RRC) Reconfiguration Complete Information

[0077] Radio Resource Control (RRC) Setup Complete Information

[0078] Report

[0079] In one embodiment, reporting the access mode of the terminal to the network device includes at least one of the following:

[0080] Autonomously reporting the access mode of the terminal to the network device

[0081] After receiving a request from the network device to obtain the access mode, reporting the access mode of the terminal to the network device

[0082] The terminal can autonomously report the access mode of the terminal to the network device so that the network device can determine the access mode of the terminal in a timely manner; the terminal can also report the access mode of the terminal to the network device after receiving a request from the network device to obtain the access mode, and if the request is not received, the terminal can refrain from reporting the access mode to avoid occupying communication resources.

[0083] Figure 4 It is a schematic flowchart of another access mode reporting method shown according to an embodiment of the present disclosure. As Figure 4 shown, reporting the access mode of the terminal to the network device after receiving a request from the network device to obtain the access mode includes:

[0084] In step S401, save the access mode in a report variable

[0085] In step S402, after receiving a request from the network device to obtain the access mode, generate a report according to the report variable and send the report to the network device.

[0086] In one embodiment, after determining its own access mode, the terminal can save the access mode in a report variable. When receiving a request from a network device to obtain the access mode, it can generate a report based on the report variable. Then, the report carries the access mode of the terminal, and further, by sending the report to the network device, the reporting of the access mode can be achieved. The network device can determine the access mode reported by the terminal by parsing the received report.

[0087] In one embodiment, the report variable includes at least one of the following:

[0088] Minimization Drive Test (MDT) report variable, such as logged MDT report variable (VarLogMeasReport);

[0089] Radio Link Failure (RLF) report variable (VarRLF-Report);

[0090] Random Access (RA) report variable (VarRA-Report);

[0091] Mobility history report variable (VarMobilityHistoryReport);

[0092] Connection Establishment Failure (CEF) report variable (VarConnEstFailReportList);

[0093] Handover success report variable (VarSuccessHO-Report);

[0094] Recorded measurement report variable (logMeasReport).

[0095] The following takes the logged MDT report variable, handover success report variable, and mobility history report variable as examples to exemplarily illustrate the method of reporting the access mode through a report.

[0096] For example, when the terminal performs logged MDT and fails to find a cell to camp on. In this case, the information element anyCellSelectionDetected in the logged MDT report variable is true, and the terminal can save the access mode in the logged MDT report variable. Subsequently, when receiving a request from the network device to obtain the access mode, it can generate a report based on the logged MDT report variable and send the report to the network device.

[0097] For example, after a wireless link failure or handover failure occurs at the terminal and no cell is found for residence, in this case, the information element in the RLF report variable is true

[0098] When performing logged MDT, no cell is found for residence. In this case, the information element noSuitableCellFound in the logged MDT report variable is true, and the terminal can save the access mode in the RLF report variable. Subsequently, after receiving a request from the network device to obtain the access mode, a report can be generated based on the RLF report variable and sent to the network device.

[0099] For example, when the terminal performs mobility history report variable recording and no cell is found for residence (i.e., the terminal is in the any cell selectiong state), in this case, the terminal can save the access mode in the mobility history report variable. Subsequently, after receiving a request from the network device to obtain the access mode, a report can be generated based on the mobility history report variable and sent to the network device.

[0100] In addition, the recorded measurement report variable and the RLF report variable can be included in the terminal information response message. The terminal can save the access mode in the recorded measurement report variable and / or the RLF report variable and generate a report and send it to the network device subsequently, or can also carry the access mode and send it to the network device through information other than the recorded measurement report variable and the RLF report variable in the terminal information response message.

[0101] In one embodiment, when a preset condition is met, the access mode of the terminal is reported to the network device, where the preset condition includes at least one of the following:

[0102] No cell is found for residence;

[0103] The access mode has changed;

[0104] When reporting cell information recording.

[0105] When the terminal fails to camp on a cell (acceptable cell and / or suitable cell), that is, when the terminal is in the anycell selection state, the network device can also determine that the terminal fails to camp on a cell. The terminal can report its access mode to the network device so that the network device can accurately determine the reason why the terminal fails to camp on a cell. For example, after learning the access mode of the terminal, the network device can determine whether the terminal can access the cell at its current location based on the current access mode. If the terminal can access the cell at its current location, it can be determined that the failure of the terminal to camp on a cell is due to a problem with the network coverage at the terminal's current location. If the terminal cannot access the cell at its current location based on the current access mode, it can be determined that the failure of the terminal to camp on a cell is due to the current access mode of the terminal.

[0106] When the access mode of the terminal changes, the terminal can report its access mode to the network device so that the network device can timely learn the changed access mode of the terminal.

[0107] When the terminal reports the cell information record, it can report its access mode to the network device. For example, it can report the access mode through the cell information report so that the network device can determine the access mode of the terminal according to the received cell information. Among them, the terminal can report its access mode to the network device only when reporting the cell information record of a specific cell or the cells in a specific cell list.

[0108] Figure 5 It is a schematic flowchart of an access mode receiving method shown according to an embodiment of the present disclosure. The access mode receiving method shown in this embodiment can be executed by a network device. The network device can communicate with a terminal. The network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station. The terminal includes, but is not limited to, a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device.

[0109] As Figure 5 shown, the access mode receiving method may include the following steps:

[0110] In step S501, receive the access mode of the terminal reported by the terminal.

[0111] According to an embodiment of the present disclosure, the network device can receive the access mode reported by the terminal (such as the access mode of the terminal in the currently camped cell), and then learn the access mode of the terminal, so that when the terminal fails to camp on a cell, the network device can accurately determine whether the failure of the terminal to camp on a cell is due to the access mode of the terminal or due to a problem with the network coverage at the terminal's current location.

[0112] It should be noted that after learning about the access mode of the terminal, the network device can perform operations as needed, not limited to the above determination of the reason why the terminal fails to find a cell to camp on.

[0113] In one embodiment, the access mode includes at least one of the following:

[0114] Standalone Non-Public Network (SNPN) access mode;

[0115] Cell Access Group (CAG)-only access mode, where when receiving the CAG-only access mode reported by the terminal, the network device can also receive the list of CAG cell identifiers allowed for access reported by the terminal;

[0116] Public-Non-Public Integrated Network (PNI-NPN) access mode;

[0117] Public Land Mobile Network (PLMN) access mode.

[0118] When the access mode of the terminal is the SNPN access mode, the terminal can only select and register with the SNPN. The SNPN does not rely on the network functions of the PLMN, so the terminal does not support the handover between the SNPN and the PLMN.

[0119] When the access mode of the terminal is the PNI-NPN access mode, the terminal can (instead of only) access the CAG. The CAG, translated as Closed Access Group, refers to a group composed of one or more cells that only allow terminals subscribed to the CAG to access. Among them, when the terminal subscribes to the CAG, two pieces of information can be configured in the subscription information. One is the list of CAGs supported by the terminal (such as the allowed CAG ID list), and the other is the identifier indicating whether the terminal can only access the network through CAG cells. The terminal configured with this identifier can only access the network through CAG cells.

[0120] Among them, the access mode of the terminal configured with the CAG-only indication is the CAG-only access mode, and this terminal can only select a CAG cell from the allowed CAG ID list to access the network.

[0121] The PNI-NPN relies on the network functions of the PLMN. Therefore, for a terminal not configured with the CAG-only indication, it supports the handover between the PNI-NPN and the PLMN.

[0122] When the access mode of the terminal is the PLMN mode, the terminal can (instead of only) access the PLMN.

[0123] In one embodiment, after learning the access mode of a terminal, if the network device determines that the terminal fails to find a cell to camp on, it can determine whether the terminal can access the cell at the terminal's current location based on the current access mode. If the terminal can access the cell at the current location, it can be determined that the failure of the terminal to find a cell to camp on is due to a problem with the network coverage at the terminal's current location. If the terminal cannot access the cell at the current location, it can be determined that the failure of the terminal to find a cell to camp on is due to the current access mode of the terminal.

[0124] For example, if the access mode of the terminal is the CAG-only access mode and the cell covering the terminal's current location does not belong to the allowed CAG ID list, the terminal will fail to find a cell to camp on. In this case, since the network device can determine that the access mode of the terminal is the CAG-only access mode and can determine that the cell at the terminal's current location does not belong to the allowed CAG ID list of the terminal, it can be determined that the reason for the terminal's failure to find a cell to camp on lies in the access mode of the terminal. If the access mode of the terminal is the CAG-only access mode and the cell at the terminal's current location belongs to the allowed CAG ID list of the terminal, then for the situation where the terminal fails to find a cell to camp on, the network device can determine that the reason for the terminal's failure to find a cell to camp on lies in a problem with the cell covering the terminal's current location.

[0125] It should be noted that the terminal's search for a cell to camp on can be carried out in the connected state or in the idle state. For example, the terminal searches for a cell to camp on during the process of cell selection or cell reselection. Among them, the cells searched for include at least one of the following two types:

[0126] Acceptable cells, suitable cells. The definitions of these two types of cells can refer to the limitations in related technologies, and the present disclosure will not elaborate further.

[0127] In one embodiment, the access mode of the terminal reported by the receiving terminal includes:

[0128] The access mode of the terminal reported by the receiving terminal through implicit indication; and / or

[0129] The access mode of the terminal reported by the receiving terminal through explicit indication.

[0130] The manner in which the terminal reports the access mode of the terminal to the network device can be reported through implicit indication or through explicit indication. The following uses several embodiments to exemplarily illustrate the two methods of explicit indication and implicit indication.

[0131] In one embodiment, the access mode of the terminal reported by the receiving terminal through explicit indication includes: receiving cell information of the first cell in which the terminal camps, where the cell information is used to determine the access mode of the terminal.

[0132] When the terminal camps in the first cell, cell selection or cell reselection can be performed. During this process, the terminal can look for a second cell to camp (it may not find a second cell to camp, or it may find a second cell to camp). Among them, the terminal can report the cell information of the first cell to the network device so that the network device can determine the state of the first cell based on the cell information of the first cell and then make appropriate configurations.

[0133] During this process, the terminal can indicate the access mode of the terminal through the cell information, so that the network device can determine the access mode of the terminal according to the cell information. Accordingly, there is no need to separately send indication information (separate uplink information or partial fields / information elements in the uplink information) to indicate the access mode of the terminal, which is beneficial to saving communication resources.

[0134] In one embodiment, the cell information includes at least one of the following:

[0135] PLMN identifier;

[0136] PNI-NPN identifier;

[0137] Network identifier;

[0138] CAG identifier;

[0139] SNPN identifier.

[0140] In one embodiment, since when the terminal camps in the first cell, the access mode of the terminal is applicable to the first cell, there is an association between the information of the first cell and the access mode when the terminal camps in the first cell. Therefore, the access mode when the terminal camps in the first cell can be indicated by reporting the information of the first cell.

[0141] For example, when the access mode of the terminal is the SNPN access mode, then the first cell in which the terminal camps belongs to the SNPN, and the cell information of the first cell includes the SNPN identifier. Therefore, the network device can determine that the access mode of the terminal is the SNPN access mode according to the SNPN identifier reported by the terminal.

[0142] Similarly, based on the PNI-NPN identifier reported by the terminal, the network device can determine that the access mode of the terminal is the PNI-NPN access mode; based on the PLMN identifier and the CAG identifier reported by the terminal, it can also determine that the access mode of the terminal is the PNI-NPN access mode; based on the PLMN identifier and the NID identifier reported by the terminal, it can also determine that the access mode of the terminal is the SNPN access mode.

[0143] In one embodiment, the access mode of the terminal reported by the receiving terminal through implicit indication includes: receiving the CAG-only indication sent by the terminal, where the CAG-only indication is used to indicate that the terminal is in the CAG-only access mode.

[0144] In one embodiment, when the access mode of the terminal is the CAG-only access mode, since it is difficult to indicate the CAG-only access mode through cell information, the access mode of the terminal can be indicated by explicit indication, for example, by sending a CAG-only indication to the network device, and the network device can determine that the access mode of the terminal is the CAG-only access mode based on the CAG-only indication sent by the terminal.

[0145] According to the above embodiments related to explicit indication and implicit indication, when the access mode of the terminal is the SNPN access mode, or the PLMN access mode, or the PNI-NPN access mode, the terminal can choose to report the access mode of the terminal through implicit indication (for example, reporting through cell information), or report the access mode of the terminal through explicit indication (for example, when there is no recorded cell information, reporting through explicit indication).

[0146] In one embodiment, the access mode is carried in at least one of the following:

[0147] Terminal information response message;

[0148] Terminal auxiliary information;

[0149] Radio Resource Control (RRC) reestablishment complete information;

[0150] Radio Resource Control (RRC) resume complete information;

[0151] Radio Resource Control (RRC) reconfiguration complete information;

[0152] Radio Resource Control (RRC) establishment complete information;

[0153] Report.

[0154] In one embodiment, the access mode of the terminal reported by the receiving terminal includes at least one of the following: receiving the access mode of the terminal reported independently by the terminal; sending a request to the terminal to obtain the access mode, and receiving the access mode of the terminal reported by the terminal.

[0155] The network device can receive the access mode reported independently by the terminal upwards, so that the network device can determine the access mode of the terminal in time; the network device can also first send a request to the terminal to obtain the access mode, and then receive the access mode reported by the terminal. When the terminal does not receive the request, it can not report the access mode of the terminal, so as to avoid occupying communication resources.

[0156] In one embodiment, the sending a request to the terminal to obtain the access mode and receiving the access mode of the terminal reported by the terminal includes: sending a request to the terminal to obtain the access mode, and receiving the report reported by the terminal; determining the access mode of the terminal according to the report.

[0157] After determining its own access mode, the terminal can save the access mode in the report variable. When receiving the request from the network device to obtain the access mode, it can generate a report according to the report variable. Then the report carries the access mode of the terminal, and then sends the report to the network device, so as to realize the reporting of the access mode. The network device can determine the access mode reported by the terminal by parsing the received report.

[0158] In one embodiment, the report variables of the report include at least one of the following:

[0159] Minimization of Drive Tests (MDT) report variable;

[0160] Radio Link Failure (RLF) report variable;

[0161] Random Access (RA) report variable;

[0162] Mobility History report variable;

[0163] Connection Establishment Failure (CEF) report variable;

[0164] Handover Success report variable;

[0165] Record Measurement report variable.

[0166] For example, when the terminal performs logged MDT and fails to find a cell to camp on, in this case, the information element anyCellSelectionDetected in the logged MDT report variable is true, and the terminal can save the access mode in the logged MDT report variable. Subsequently, after receiving a request from the network device to obtain the access mode, a report can be generated based on the logged MDT report variable and sent to the network device.

[0167] For example, after the terminal experiences a radio link failure or a handover failure and fails to find a cell to camp on, in this case, the information element in the RLF report variable is true

[0168] When performing logged MDT and failing to find a cell to camp on, in this case, the information element noSuitableCellFound in the logged MDT report variable is true, and the terminal can save the access mode in the RLF report variable. Subsequently, after receiving a request from the network device to obtain the access mode, a report can be generated based on the RLF report variable and sent to the network device.

[0171] As Figure 7 shown, the terminal can report the access mode of the terminal to the network device.
