[0002] This application claims priority to Chinese Patent Application No. 201910750380.3, filed in China on August 14, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to a method, terminal and network device for reporting status information. Background Technology

[0004] In related technologies, the handover process involves attempting to switch to a candidate cell. For self-organizing networks (SON) or minimized drive-test (MDT), the terminal needs to report the following information: information related to the last successful Random Access Channel (RACH), a Radio Link Failure (RLF) report, and the failure type. Based on this information, the network device can perform relevant configuration operations.

[0005] To adapt to the development of communication technologies, related technologies allow terminals to attempt handover to multiple candidate cells multiple times, such as the Conditional Handover (CHO) process. However, after introducing the handover process with multiple attempts to multiple candidate cells, the way terminals report the handover status information in related technologies can no longer meet the configuration requirements of network devices.

[0006] Summary of the Invention

[0007] This disclosure provides a method, terminal, and network device for reporting status information, in order to solve the problem that the way the terminal reports the status information of the handover process in related technologies cannot meet the configuration requirements of the network device after the introduction of a handover process that involves multiple attempts to hand over to multiple candidate cells.

[0008] To solve the above-mentioned technical problems, the embodiments of this disclosure are implemented as follows:

[0046] To facilitate understanding of the embodiments of this disclosure, the condition switching CHO process is first described below.

[0047] Specifically, the CHO process mainly includes the following steps:

[0048] S1: The source node sends a handover request to one or more target nodes.

[0049] S2: The target node sends a handover confirmation message back to the source node.

[0050] S3: The source node sends configuration information for conditional switching to the terminal, such as the user equipment (UE).

[0051] S4: The UE evaluates whether the candidate cell meets the conditions, and if it does, selects a target cell for handover.

[0052] S5: The UE initiates a random access procedure in the selected target cell.

[0053] S6: The UE sends a handover completion message to the target node.

[0054] S7: The source node sends a command to other target nodes to cancel the condition switching.

[0055] S8: Other target nodes send a condition switch cancellation confirmation command to the source node.

[0056] Optionally, the handover process in this embodiment of the disclosure can be a normal handover process that attempts to hand over to multiple candidate cells multiple times, or a CHO process that attempts to hand over to multiple candidate cells multiple times.

This handover process status information may include random access procedure status information corresponding to the target cell in the handover process, connection failure information corresponding to the target cell in the handover process, and / or RLF information during the handover process. Compared with reporting methods in related technologies, the terminal using this disclosure can effectively report relevant handover process status information. Even after introducing a handover process involving multiple attempts to hand over to multiple candidate cells, it can still meet the configuration requirements of the network device, thereby enabling the network device to optimize relevant configurations based on the information reported by the terminal.

[0079] 1) The number of times to switch once or multiple times.

[0080] 2) The number of times the switching failed once or multiple times.

[0081] 3) The number of successful handover attempts in one or more handover attempts.

[0091] 13) In one or more reconstructions, at least one of the following is selected for each candidate cell: measurement result, cell ID, cell group ID, and frequency ID.

[0092] 14) Time-related information. For example, this time-related information could be the time information when a connection failure occurs, such as timeConnFailure.

[0093] 15) Location-related information. For example, this location-related information could be the location of the terminal when the handover or reconstruction fails.

[0094] It should be noted that the number in 1) above can be understood as the total number of handover attempts made by the terminal, for example, N. The number in 2) above can be understood as the total number of failed handover attempts made by the terminal. The number of handover attempts in 3) above can be understood as the nth handover attempt that was successfully connected, for example, the N+1th handover attempt. The scenarios corresponding to 1) to 3) above can be those where the terminal only makes handover attempts, such as conditional handover CHO attempts.

[0095] The number in 4) above can be understood as the total number of times the terminal attempted to rebuild. The number in 5) above can be understood as the total number of times the terminal failed to rebuild. The number of rebuild attempts in 6) above can be understood as the number of rebuild attempts corresponding to the last successful access. The scenarios corresponding to 4) to 6) above can be those where the terminal only attempted rebuilds.

[0096] The number of times in 7) above can be understood as the total number of handover attempts and reconstruction attempts made by the terminal. The number of times in 8) above can be understood as the total number of handover failures and reconstruction failures made by the terminal.

The scenarios corresponding to 7) to 9) above can be that the terminal only makes reconstruction attempts, or the terminal may make both handover attempts (such as CHO attempts) and reconstruction attempts. For example, the handover process performed by the terminal may include: CHO1, CHO2, CHO3, CHO4 and Re-est1; if the candidate cell is successfully accessed during Re-est1, then the number of handover attempts and reconstruction attempts is 5, the number of handover failures is 4, and the number of reconstruction attempts that were successfully completed is the first reconstruction attempt.

[0097] The target information in 10) and 11) above may include, but is not limited to, at least one of the following:

[0103] Measurement results used to determine if the triggering conditions for a switching failure are met.

[0104] The measurement result in 13) above may also be the measurement result of at least one of the current cell, candidate cell, and neighboring cell; the neighboring cell may be a co-frequency neighboring cell, an inter-frequency neighboring cell, and / or an inter-frequency RAT cell. The frequency identifier in 13) above may be at least one of the following: carrier identifier, band width identifier, frequency band identifier, etc.

[0105] Optionally, the measurement results in this embodiment may include at least one of the following:

[0106] Reference Signal Received Power (RSRP);

[0108] Signal to Interference plus Noise Ratio (SINR).

[0109] Furthermore, the random access procedure failure information in this embodiment may also include at least one of the following:

[0110] 16) Triggering conditions for one or more failed switching attempts.

[0111] 17) The trigger condition number corresponding to one or more failed switching attempts.

[0112] 18) Triggering conditions for one or more failed reconstructions.

[0113] 19) The trigger condition number corresponding to one or more failed reconstructions.

[0114] Specifically, the triggering condition in 16) above can be the triggering condition corresponding to each handover failure, or the triggering condition corresponding to the last handover failure before successful access. The triggering condition number in 17) above can be the triggering condition number corresponding to each handover failure, or the triggering condition number corresponding to the last handover failure before successful access. The triggering condition in 18) above can be the triggering condition corresponding to each reconstruction failure, or the triggering condition corresponding to the last reconstruction failure before successful access. The triggering condition number in 19) above can be the triggering condition number corresponding to each reconstruction failure, or the triggering condition number corresponding to the last reconstruction failure before successful access.

[0115] For 16) to 19) above, the first time may include any one of the following:

[0116] There is only one attempt, any attempt, and the last attempt before successful connection.

[0117] And / or, the plurality of times may include any one of the following:

[0118] All switch and rebuild attempts, all switch attempts and all rebuild attempts.

[0119] In this embodiment of the disclosure, optionally, the success information of the random access procedure may include at least one of the following:

[0120] The number of times the preamble was transmitted in the last successful random access procedure;

[0121] The result of the last successful random access conflict detection;

[0122] A successful handover requires at least one of the following: the trigger condition, measurement result, cell identifier, cell group identifier, and frequency identifier.

[0123] At least one of the following must be present for a successful reconstruction: the triggering condition, measurement result, cell identifier, cell group identifier, and frequency identifier.

[0124] The number of handover attempts before a successful random access;

[0125] The number of reconstruction attempts prior to successful random access;

[0126] The number of handover and rebuild attempts prior to successful random access;

[0127] At least one of the following: trigger condition, measurement result, cell identifier, cell group identifier, and frequency identifier, corresponding to each handover attempt before successful random access;

[0128] At least one of the following: measurement result, cell identifier, cell group identifier, and frequency identifier, corresponding to each reconstruction attempt prior to successful random access.

[0129] Understandably, the measurement results included in the successful random access procedure information can be the measurement results of at least one of the corresponding local cell, candidate cell, and neighboring cell; the neighboring cell can be a co-frequency neighboring cell, an inter-frequency neighboring cell, and / or an inter-frequency RAT cell. The frequency identifier can be at least one of the following: carrier identifier, band width identifier, frequency band identifier, etc.

[0130] In this embodiment of the disclosure, when the status information of the handover process reported by the terminal includes triggering conditions (such as triggering conditions corresponding to a handover attempt, triggering conditions corresponding to a handover failure, etc.), the status information of the handover process may further include: the effective range information corresponding to the triggering conditions.

[0131] The effective range information corresponding to the trigger condition may include the identifier (ID) of the effective range. This effective range information can help network devices (NWs) determine the effective range of the configured trigger conditions.

[0132] In one implementation, if triggering condition 1 corresponds to a successful CHO in cell 1 and cell 2, but a failed CHO in cell 3, then the network device can configure the effective range of triggering condition 1 to be cell 1 and cell 2.

[0133] In this embodiment of the disclosure, when a connection failure occurs at the terminal, the status information of the handover process reported by the terminal may further include: connection failure timing information.

[0134] Optionally, the connection failure timing information may include any one of the following:

[0135] (1) The duration from the start of executing the target handover command until the connection establishment of the target cell corresponding to the target handover command fails. That is, the terminal will report different connection failure timing information for different target handover commands. If the target handover command is a CHO command, then the start of executing the target handover command can be from the start of satisfying the triggering condition corresponding to the CHO command.

[0136] For example, if the target handover command indicates a handover to cell 1, the corresponding connection failure timing information can be: the duration from the start of the handover to cell 1 until the handover to cell 1 fails.

[0137] (2) The duration from the first triggering of the handover process until the connection establishment of the target cell corresponding to the target handover command fails. That is, the terminal will report different connection failure timing information for different target handover commands.

[0138] For example, if the first handover to cell 1 is triggered and the target handover command indicates a handover to cell 4, the corresponding connection failure time information could be: the duration from the first trigger of the handover to cell 1 until the handover to cell 4 fails. Between cell 1 and cell 4, there may have been handover attempts to cell 1 and cell 3.

[0139] (3) The duration from the receipt of the target handover command until the connection establishment of the target cell corresponding to the target handover command fails. That is, the terminal will report different connection failure timing information for different target handover commands.

[0140] Among them, the target switching commands in (1) to (3) above can also be called specific switching commands. The target switching command can be any one of the following:

[0141] The first toggle command to be triggered; for example, the first CHO command to be triggered, i.e., the first CHO condition to be met.

[0142] The handover command corresponding to the candidate cell for the current handover or reconstruction;

[0143] The handover command corresponding to the last handover candidate cell or the candidate cell to be rebuilt before successfully handing over to a candidate cell;

[0144] The handover command corresponding to the last handover candidate cell or the candidate cell to be rebuilt before successfully reconstructing to a candidate cell or other cells.

[0145] In this embodiment of the disclosure, when the terminal reports the status information of the handover process, the reporting can be triggered by a request from the network device or by its own situation. Optionally, step 101 above may include:

[0146] The handover process status information is sent to the network device under any of the following conditions:

[0147] The terminal receives a request from the network device requesting the terminal to report the status information of the handover process;

[0148] The connection failed during the switching of the terminal (e.g., CHO).

[0149] The request information may request the terminal to report at least one of the following:

[0150] Random access status information;

[0151] Connection failed message;

[0152] RLF information during the handover process.

[0153] Optionally, a connection failure during the handover process of the terminal may include at least one of the following:

[0154] The entire switching process failed; for example, the entire CHO process failed.

[0155] The timer that caused the switching failure times out; this timer is, for example, T304 or another similar timer.

[0156] The terminal failed to access a candidate cell before the preset timer (e.g., T304 or other similar timer T304-like) expired; for example, before the T304 timeout, the terminal tried to switch to multiple candidate cells multiple times, but failed to access a candidate cell.

[0157] Reconstruction failed before the preset timer (e.g., T304 or other similar timer T304-like) expired;

[0158] One or more switching commands during the switching process failed to trigger a switching attempt.

[0159] The handover attempt for one or more target cells during the handover process failed;

[0160] One or more rebuilds during the switching process failed;

[0161] RLF occurred during the handover process;

[0162] After a handover failure or RLF, a reconstruction process is initiated; for example, during the reconstruction process, the terminal sends an indication message through a reconstruction completion message, indicating that there is RLF or HOF information to be reported.

[0163] After a handover failure or RLF (Recurrent Least Fault) report, cell selection is performed. For example, if the selected cell is a target cell for a CHO (Cell-Honored Request), the terminal performs a CHO. During the handover process, the terminal sends a reconfiguration completion message indicating that there is RLF or HOF information to be reported.

[0164] Please refer to Figure 2, which is a flowchart of a status information reporting method provided in an embodiment of this disclosure. The method is applied to a network device. As shown in Figure 2, the method includes the following steps:

[0165] Step 201: Receive the status information of the handover process from the terminal.

[0166] The status information of the switching process may include at least one of the following:

[0167] The random access procedure status information corresponding to the target cell during the handover process;

[0168] Connection failure information corresponding to the target cell during the handover process;

[0169] RLF information during the handover process.

[0170] Optionally, the switching process is a conditional switching process.

[0171] It is easy to understand that, compared with the reporting methods in related technologies, the terminal using the embodiments of this disclosure can effectively report the status information of the handover process. Even after introducing a handover process that attempts to hand over to multiple candidate cells, the configuration requirements of the network device can still be met, thereby enabling the network device to optimize the relevant configuration based on the information reported by the terminal.
