[0115] Before introducing the technical solution of the embodiments of the present application, the related technologies are introduced first.

[0116] In the related art, a network can enter a network energy saving (NES) state or a non-NES state to serve multiple user equipments (UEs). When the network state transitions, especially from a non-NES state to an NES state, multiple UEs may need to perform handovers. To reduce the large signaling overhead of multiple UEs during network state transitions and enable the network to quickly transition states, the enhancement of conditional handover (CHO) is adopted to support network energy saving.

[0117] New Radio (NR) supports CHO. CHO is a method where corresponding access resources and execution conditions are configured for the UE, and the UE monitors itself and actively initiates a handover when the conditions are met. It can be used to solve the handover failure problems that may occur in high-frequency or high-speed mobile scenarios. In addition, NES also supports the mechanism of barring legacy UEs (i.e., prohibiting legacy UEs from accessing NES cells) to prevent legacy UEs from accessing NES cells.

[0118] However, in the following two scenarios, ultimately, the UE does not have a suitable serving cell, thus entering or remaining in the idle state, resulting in a degraded user experience.

[0119] In Scenario 1, when the serving cell enters the network energy saving state, such as shutting down the cell (or shutting down the antenna corresponding to the UE), the UE needs to perform a handover. Especially when CHO is configured, the UE will initiate a handover based on the conditions configured by the network on its own. However, there may be a situation where when the serving cell enters the NES mode, the UE does not have a suitable handover cell, or a suitable handover cell is found but the handover ultimately fails, and the current serving cell or antenna has been shut down. Therefore, according to the current mechanism, a reconstruction will be triggered. In particular, when the UE initiates reselection or reconstruction, there may be no eligible cells, such as all detectable cells have entered the NES state.

[0120] In Scenario 2, a UE in the idle state, especially a legacy UE, may camp on a supporting cell that supports NES. When this cell transitions from a non-NES state to an NES state, the legacy UE may be barred. When the UE wants to enter the connected state (such as having an uplink service), the current serving cell cannot support it. According to the current reselection mechanism, the cell reselected by the UE may still bar the legacy UE, or there may be no cell that can admit the legacy UE due to unreasonable network configuration.

[0121] Based on this, in the embodiments of the present application, the terminal reports first indication information related to network energy saving to the network device; the first indication information is used for the network device to optimize the energy saving configuration of the network.

[0122] See Figure 1 , Figure 1 is a schematic flow diagram of the information transmission method in the embodiments of the present application, applied to the terminal. The method includes step 101:

[0123] Step 101: Report first indication information related to network energy saving to the network device; the first indication information is used for the network device to optimize the energy saving configuration of the network.

[0124] As an example, the network device may refer to a network management or a trace collection entity (TCE) or a base station.

[0125] As an example, the terminal may refer to a user equipment (UE).

[0126] In some embodiments, the first indication information is used to indicate at least one of the following:

[0127] Conditional handover failure;

[0128] Handover failure;

[0129] Cell reselection failure;

[0130] Cell reselection is successful but the channel condition of the reselected cell is poor and / or there is significant interference, and / or the cell with the best channel condition is not successfully reselected;

[0131] RRC connection establishment failure;

[0132] The reason for conditional handover failure;

[0133] The reason for handover failure;

[0134] The reason for cell reselection failure;

[0135] The reason for RRC connection establishment failure;

[0136] The identifier of the serving cell or the identifier of the resident cell;

[0137] The occurrence time of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure;

[0138] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the network energy saving status of this cell or the network energy saving technology used;

[0139] The identifier of a neighboring cell in case at least one of the following occurs: conditional handover failure, handover failure, cell reselection failure, RRC connection establishment failure;

[0140] The network energy saving status or the network energy saving technology used by a neighboring cell in case at least one of the following occurs: conditional handover failure, handover failure, cell reselection failure, RRC connection establishment failure;

[0141] The execution thresholds of one or more conditional handover candidates in case at least one of the following occurs: conditional handover failure, handover failure, cell reselection failure, RRC connection establishment failure;

[0142] The measurement results of one or more neighboring cells in case at least one of the following occurs: conditional handover failure, handover failure, cell reselection failure, RRC connection establishment failure.

[0143] As an example, the reasons for the conditional handover failure may be at least one of the following, which can be characterized by an identifier specified by the protocol or allocated by the network:

[0144] The first reason: When the network enters the NES state, there is no cell that meets the conditions for conditional handover execution, resulting in the inability to perform a handover, and the serving cell has entered the NES state, leading to a radio link failure / or handover failure because it cannot serve the UE. The terminal can record and report the cell identifier of the conditional handover target cell and one or more of the signal measurement values such as RSRP, RSRQ, SINR, BLER, etc., so that the network side can know which cell coverage has a hole in this area and / or the time when the serving cell enters the NES state;

[0145] The second reason: Although the handover conditions are met, the access to the target cell fails. Specifically, it may be a radio link failure, or the target cell prohibits a certain type of UE (such as a legacy UE, a UE that does not support NES) from accessing. The terminal can record and report the cell identifier of the conditional handover target cell and the signal measurement values.

[0146] As an example, the reasons for the handover failure may be at least one of the following, which can be characterized by an identifier specified by the protocol or allocated by the network:

[0147] The first reason: The channel quality of the serving cell deteriorates, and no handover command is received, resulting in a radio link failure. The terminal can record and report the signal measurement values of the cell when the failure occurs;

[0148] The second reason: A handover command is received, but the access to the target cell fails. Specifically, it may be a radio link failure, or the target cell prohibits a certain type of UE (such as a legacy UE, a UE that does not support NES) from accessing;

[0149] For the third reason, the serving cell enters the NES state and the terminal does not support the NES state. Report this handover failure reason so that the network side can know that the handover problem of the old terminal is caused by the NES state conversion of the network side, rather than the handover problem of the new terminal that supports NES.

[0150] As an example, the reasons for cell reselection failure include: meeting the cell reselection threshold / condition and / or cell residence threshold, but the target cell prohibits access of a certain type of UE (such as a legacy UE, a UE that does not support NES).

[0151] As an example, when the cell reselection is successful but the channel condition of the reselected cell is poor and / or there is significant interference, and / or the best channel condition cell is not successfully reselected, record and / or report one of the following information:

[0152] The priority of the reselected cell and / or the frequency it is on (in the case of network-configured priority), and / or the corresponding measurement value;

[0153] The measurement result of the best cell and / or the NES state;

[0154] The measurement result of other high-priority cells and / or the NES state.

[0155] As an example, the reasons for RRC connection establishment failure include: when a legacy UE needs to initiate RRC connection establishment after residing in this cell, the serving cell prohibits access of the legacy UE, and the neighboring cell prohibits access of the legacy UE.

[0156] As an example, when the above-mentioned multiple failures occur, the ID of the neighboring cell, and the ID of the neighboring cell can be one or more. For example, one may be the handover target cell, or for CHO and reselection, report one or more IDs of neighboring cells according to network configuration.

[0157] As an example, the energy-saving state of the network or the network energy-saving technology may be one or more of the following: using the SSB-less technology, prohibiting access of non-NES terminals, enabling cell DTX and / or cell DRX, and cell shutdown.

[0158] In some embodiments, reporting the first indication information related to network energy saving to the network device includes:

[0159] Reporting the first indication information related to network energy saving to the network device based on the communication protocol;

[0160] Or,

[0161] Reporting the first indication information related to network energy saving to the network device based on the configuration information sent by the network device.

[0162] As an example, the configuration information is the configuration information of the network energy saving state (NES).

[0163] As an example, the configuration information is used to configure the terminal to record and report the first indication information. The first indication information is information related to network energy saving technology.

[0164] In some embodiments, reporting the first indication information related to network energy saving to the network device includes:

[0165] When the terminal is in the connected state or in the process of transitioning to the connected state, reporting the first indication information related to network energy saving to the network device;

[0166] Or,

[0167] Reporting the first indication information related to network energy saving to the network device through an RRC message or in a radio link failure report;

[0168] Or,

[0169] Reporting the first indication information related to network energy saving to the network device through auxiliary information;

[0170] Or,

[0171] When the network device requests the terminal to send the first indication information, reporting the first indication information related to network energy saving to the network device;

[0172] Or,

[0173] When the reporting condition configured by the network device is met, reporting the first indication information related to network energy saving to the network device;

[0174] Or,

[0175] Periodically reporting the first indication information related to network energy saving to the network device;

[0176] Or,

[0177] Proactively reporting the first indication information related to network energy saving to the network device;

[0178] Or,

[0179] When the network device requests the terminal to send the first indication information again after the terminal fails to report the first indication information, reporting the first indication information related to network energy saving to the network device.

[0180] As an example, the RRC message may include an RRC reestablishment request message.

[0181] In the embodiments of the present application, the following advantages are achieved:

[0182] (1) The terminal reports first indication information related to network energy saving. The first indication information includes information such as the reason for mobility handover failure, time, measurement, and the NES status of neighboring cells. Among them, the first indication information is used to help the network side optimize the network energy saving configuration. For example, optimizing the time for cells within the area to enter the NES state, as well as optimizing the CHO execution conditions, reselection or measurement priority mobility-related parameters, so that the terminal can be switched to a suitable cell.

[0183] (2) The reporting of the first indication information can be when the UE reports in the cell corresponding to the source base station or when the UE reports in other cells.

[0184] (3) It can be extended to other technical fields, such as RedCap. For example, when a RedCap UE switches / conditionally switches from a cell supporting RedCap to other cells, and the UE switches due to the non-support of RedCap by other cells, or when a RedCap UE initiates an RRC connection establishment and the local area bars the RedCap UE (i.e., prohibits the RedCap UE from accessing the local area) and the reselected cell also bars the RedCap UE, then the RedCap UE can report the first indication information to the network device. The first indication information includes information such as the reason for handover failure, time, measurement, and the support status of RedCap in the local area and neighboring cells, for the network to optimize the energy saving configuration of the network, so that the RedCap UE can be switched to a suitable cell.

[0185] See Figure 2 , Figure 2 is a schematic flowchart of the implementation process of the information transmission method in the embodiments of the present application, which is applied to a network device. The method includes step 201:

[0186] Step 201: Receive the first indication information related to network energy saving reported by the terminal; the first indication information is used for the network device to optimize the energy saving configuration of the network.

[0187] In some embodiments, the first indication information is used to indicate at least one of the following:

[0188] Conditional handover failure;

[0189] Handover failure;

[0190] Cell reselection failure;

[0191] The cell reselection is successful, but the channel conditions of the reselected cell are poor and / or there is significant interference, and / or the cell with the best channel conditions is not successfully reselected;

[0192] RRC connection establishment failure;

[0193] Reasons for conditional handover failure;

[0194] Reasons for handover failure;

[0195] Reasons for cell reselection failure;

[0196] Reasons for RRC connection establishment failure;

[0197] Identifiers of serving cells or resident cells;

[0198] Occurrence time of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure;

[0199] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the network energy saving status of this cell or the network energy saving technology used;

[0200] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the identifiers of neighboring cells;

[0201] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the network energy saving status of neighboring cells or the network energy saving technology used;

[0202] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the execution thresholds of one or more conditional handover candidates;

[0203] In the case where at least one of conditional handover failure, handover failure, cell reselection failure, and RRC connection establishment failure occurs, the measurement results of one or more neighboring cells.

[0204] As an example, the reasons for conditional handover failure can be at least one of the following, which can be characterized by an identifier specified by the protocol or allocated by the network:

[0205] The first reason is that when the network enters the NES state, there is no cell that meets the conditions for conditional handover execution, resulting in inability to perform handover. Since this cell has entered the NES state, it cannot serve the UE, leading to radio link failure / or handover failure. The terminal can record and report the cell identifier and signal measurement values of the conditional handover target cell, such as one or more of RSRP, RSRQ, SINR, and BLER, so that the network side can know which cell coverage has loopholes in this area and / or the time when the serving cell enters the NES state;

[0206] For the second reason, although the handover condition is met, the handover to the target cell fails. Specifically, it may be a radio link failure, or the target cell prohibits a certain type of UE (such as a legacy UE that does not support NES) from accessing. The terminal can record and report the cell identifier and signal measurement values of the target cell for conditional handover.

[0207] As an example, the reasons for the handover failure can be at least one of the following, which can be characterized by an identifier specified by the protocol or allocated by the network:

[0208] For the first reason, the channel quality of the serving cell deteriorates and no handover command is received, resulting in a radio link failure. The terminal can record and report the signal measurement values of the cell when the failure occurs;

[0209] For the second reason, a handover command is received, but the handover to the target cell fails. Specifically, it may be a radio link failure, or the target cell prohibits a certain type of UE (such as a legacy UE that does not support NES) from accessing;

[0210] For the third reason, the serving cell enters the NES state and the terminal does not support the NES state. Report this reason for the handover failure so that the network side can know that it is the handover problem of the old terminal caused by the NES state transition of the network side, rather than the handover problem of the new terminal that supports NES.

[0211] As an example, the reasons for the cell reselection failure include: meeting the cell reselection threshold / condition and / or the cell residence threshold, but the target cell prohibits a certain type of UE (such as a legacy UE that does not support NES) from accessing.

[0212] As an example, when the cell reselection is successful but the channel condition of the reselected cell is poor and / or there is significant interference, and / or the best channel condition cell is not successfully reselected, record and / or report one of the following information:

[0213] The priority of the reselected cell and / or the frequency it is on (when the network configures the priority), and / or the corresponding measurement values;

[0214] The measurement result of the best cell and / or the NES state;

[0215] The measurement results and / or NES states of other high-priority cells.

[0216] As an example, the reasons for the RRC connection establishment failure include: when a legacy UE needs to initiate an RRC connection establishment after camping on this cell, the camping cell prohibits the legacy UE from accessing, and the neighboring cell prohibits the legacy UE from accessing.

[0217] As an example, the ID of the neighboring cell when the above-mentioned multiple failures occur, and the ID of the neighboring cell can be one or more. For example, one may be the target cell for handover, or for CHO and reselection, report the ID of one or more neighboring cells according to the network configuration.
