Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a method, apparatus, device, and readable storage medium for optimizing configuration. Background Art

[0002] Conditional handover is a mechanism that enhances the robustness of handover or auxiliary node addition. In order to solve the problem that the channel between the terminal (for example, User Equipment (UE)) and the serving cell suddenly deteriorates (especially at high frequencies), causing the UE to be unable to complete the handover or auxiliary node addition process normally, the base station can configure the UE to trigger measurement reporting at a lower threshold, and carry a higher threshold for triggering handover in the handover (HO) command or auxiliary node addition command, which can also carry the random access resources used by the UE in the target cell. Once the handover threshold is met, the UE initiates a random access process to the target base station or cell. The source base station or cell can configure conditional handover for multiple target cells for the UE, see Figure 1 .

[0003] When a radio link failure (RLF) occurs in the serving cell, the UE performs cell selection (the UE selects a cell that meets the residency threshold to reside in). If the selected cell is a conditional handover (CHO) candidate cell configured by the network and the network side configures the terminal to attempt CHO after RLF failure, the UE can attempt CHO again; otherwise, the UE performs the reconstruction process.

[0004] Similarly, Conditional Pscell Addition / Change (CPAC) involves the network's Master Node (MN) or Secondary Node (SN) sending the conditions for adding or changing a Primary Secondary Cell (PScell) to the terminal in advance. When the terminal measures that the target PScell ​​meets the conditions, it automatically adds or changes the PScell. If CPAC fails, the network may also configure the terminal to try other CPAC candidate cells.

[0005] After the source base station configures CHO or CPAC for a terminal, the UE may encounter various situations, and the UE may attempt to access the target cell using CHO resources. After the UE successfully connects to the target cell, the network side cannot distinguish which situation the UE experienced when accessing the network, and therefore cannot optimize the handover configuration and / or random access configuration.

[0125] See also Figure 3 The embodiment of the present application provides a method for optimizing configuration. The method is performed by a network-side device, such as a network management function; a trace collection entity (TCE) or a base station. The specific steps include: Step 301.

[0126] Step 301: The terminal is configured to report CHO or CPAC related information, where the CHO or CPAC related information is used to optimize handover configuration and / or random access configuration.

[0127] In one embodiment of the present application, Figure 3 The illustrated method may further include:

[0128] Receiving CHO or CPAC related information reported by the terminal;

[0129] Conditional handover configuration optimization processing and / or random access configuration optimization processing are performed according to the relevant information of the CHO or CPAC.

[0130] In one embodiment of the present application, the relevant information of CHO or CPAC includes one or more of the following:

[0131] (1) Before or during the execution of CHO or CPAC or before the event is triggered when the CHO or CPAC succeeds, the terminal radio link management (RLM) discovers that the serving cell physical layer is at risk of desynchronization or the radio link is at risk of failure or has started a first timer;

[0132] For example, the first timer may be a T310 timer.

[0133] (2) When the terminal is in RLF, none of the configured CHOs are triggered or only one event is triggered (for example, the CHO or CPAC can configure both A5 and A3 events, where only the A5 or A3 event is triggered; or the CHO or CPAC can configure both A4 and B1 events, where only the A4 or A3 event is triggered);

[0134] (3) the terminal performs cell selection after RLF or CHO failure and selects a candidate cell for CHO, for example, by indicating through 1 bit that the terminal performs cell selection after RLF or CHO failure and selects a candidate cell for CHO;

[0135] (4) When an RLF occurs in the Master Cell Group (MCG) of the terminal, the configured CPAC is not triggered or only one event is triggered (for example, the CHO or CPAC can be configured with an A5 event and an A3 event, of which only the A5 event or the A3 event is triggered; or the CHO or CPAC can be configured with an A4 event and a B1 event, of which only the A4 event or the A3 event is triggered);

[0136] (5) Radio Resource Management (RRM) measurement values ​​of the current cell and / or neighboring cells measured by the terminal when the first timer is started;

[0137] Optionally, the RRM measurement value may be at a beam level or a cell level.

[0138] (6) The time difference between starting the first timer and receiving the CHO or CPAC configuration;

[0139] (7) When CHO or CPAC is executed, or when CHO or CPAC is successful, the timing status of the first timer (e.g., how long it has been counting) and / or the number of RLC retransmissions;

[0140] (8) CHO or CPAC candidate cell IDs configured on the network side, corresponding events, and / or thresholds or offsets corresponding to the events;

[0141] Optionally, the event may include one or more of the following: (1) A3 event; (2) A5 event; (3) A4 event; (4) B1 event; that is, the CHO or CPAC candidate cell ID configured on the network side, the corresponding A3 event, or the corresponding A5 event, or the corresponding A4 event, or the corresponding B1 event, or the corresponding A3 event and A5 event.

[0142] Optionally, the threshold value or offset includes one or more of the following: offset of A3 event (a3-offset), threshold value 1 of A5 event (a5-Threshold1), threshold value 2 of A5 event (a5-Threshold2), threshold value of A4 event (a4-Threshold), threshold value of B1 event (b1-Threshold), hysteresis, trigger time (TimeToTrigger).

[0143] (9) Random access information configured for the terminal by the cell where the CHO or CPAC failure occurs;

[0144] For example, 2-step non-contention random access or contention-based random access (2-step CFRA / CBRA), 4-step non-contention random access or contention-based random access (4-step CFRA / CBRA); further, if it is 2-step random access, can it fallback to 4-step random access, or what is the maximum number of 2-step random access attempts before falling back to 4-step random access.

[0145] (10) The time difference between the time when CHO1 or CPAC is configured and the time when the terminal successfully completes random access in the target cell (the UE sends an RRC Setup Request message in the target cell) or successfully completes the RRC connection (the UE sends an RRC Setup Complete or RRC Reconfiguration Complete message in the target cell);

[0146] (11) Time information corresponding to the relevant information of CHO or CPAC.

[0147] (12) The location information of the terminal corresponding to the relevant information of CHO or CPAC.

[0148] (13) Measurement results of the wireless network corresponding to the relevant information of CHO or CPAC.

[0149] For example, the measurement result of the wireless network includes: a measurement result of a wireless local area network (WLAN) and / or a measurement result of Bluetooth.

[0150] During the operation of the first timer, if the wireless link is restored, the first timer is stopped; otherwise, the first timer continues to run.

[0151] In one embodiment of the present application, conditional switching configuration optimization processing and / or random access configuration optimization processing are performed based on the relevant information of the CHO or CPAC, and one or more of the random access report (RA report), the radio link failure report (RLF report) and the location of the terminal.

[0152] For example, the following takes the first timer as T310 and the CHO scenario as an example, and other scenarios (such as the CPAC scenario) are similar and are not described here.

[0153] 1) If the UE detects potential physical layer desynchronization or initiates T310, or RLF occurs before any configured CHO is triggered, it indicates that the CHO triggering conditions of the candidate cell are too stringent. The CHO triggering threshold should be lowered, such as reducing a3-offset and / or a5-Threshold2, reducing the hysteresis, TimeToTrigger, and increasing a5-Threshold1.

[0154] Furthermore, based on the time difference between starting T310 and receiving the CHO configuration, and / or the timing length of T310, or the time difference between CHO triggering or execution and starting T310, the network side can more accurately understand the magnitude of adjustment of the above parameters. For example, the longer the timing length of T310, or the more RLC retransmissions, the greater the risk of RLF of the UE in the source cell. The source base station should configure CHO earlier or significantly lower the triggering or execution threshold of CHO.

[0155] 2) If the UE selects a candidate CHO cell during cell selection, it indicates that the trigger threshold corresponding to the CHO cell should be lowered so that the UE can be handed over to the cell through CHO;

[0156] 3) If the UE does not select any CHO candidate cell during cell selection, the cell selected by the UE may be considered as a candidate cell in the future;

[0157] 4) If the UE experiences the first CHO failure, the random access information configured for the cell can be combined to analyze whether the random access failure is caused by the UE not being allowed to fallback from 2-step random access (RA) to 4-step random access, but the 2-step random access has been unsuccessful;

[0158] 5) Based on the time difference between the configuration of CHO and the successful completion of random access (UE sends an RRC Setup Request message in the target cell) or the successful completion of RRC connection (UE sends an RRC Setup Complete or RRC Reconfiguration Complete message in the target cell) in the target cell, as well as the configuration information of the RA of the cell, it can be determined whether the UE takes too long to access the target cell due to excessive attempts at step 2.

[0159] In one embodiment of the present application, the step of receiving CHO or CPAC related information reported by the terminal includes:

[0160] receiving an RRC reestablishment request message or a radio link failure report sent by the terminal in a connected state or in the process of transitioning to a connected state, where the RRC reestablishment request message or the radio link failure report includes relevant information of the CHO or CPAC;

[0161] or,

[0162] Receive a message A sent by the terminal during a 2-step random access process of a target cell, where the message A includes relevant information of the CHO or CPAC.

[0163] In one embodiment of the present application, receiving CHO or CPAC related information reported by the terminal includes one of the following:

[0164] (1) sending a first request to the terminal; and receiving CHO or CPAC related information reported by the terminal according to the first request;

[0165] (2) Receiving CHO or CPAC related information proactively reported by the terminal;

[0166] (3) receiving a notification message sent by the terminal, wherein the notification message indicates that the terminal has relevant information about the CHO or CPAC; sending a second request to the terminal according to the notification message; and receiving relevant information about the CHO or CPAC reported by the terminal based on the second request.

[0167] In an embodiment of the present application, the network side device configures the terminal to report relevant information of CHO or CPAC, so that the network side device can perform conditional switching configuration optimization processing and / or random access configuration optimization processing based on the relevant information of CHO or CPAC reported by the terminal.

[0168] See also Figure 4 , an embodiment of the present application provides a method for optimizing configuration, the execution subject of the method may be a terminal, and the specific steps include: step 401.
