[0109] DAPS is a mechanism introduced to reduce user plane delay interruption during handover. Figure 1 and Figure 2 As shown, after receiving the handover command, the terminal (such as user equipment (UE)) initiates a random access process to the target base station, during which the uplink and downlink data transmission with the source base station may not be interrupted; the UE does not interrupt the data transmission process with the source base station until it receives an explicit notification from the target base station. When the UE successfully completes the establishment of the Radio Resource Control (RRC) connection in the target cell, there will be signaling interaction processes such as handover success and secondary node status transfer between the target cell and the source cell, and then the subsequent path switch process will be carried out.

[0110] See also Figure 1 , the specific steps are as follows:

[0111] 1.Handover Command with "daps-HO" / "dapsConfig" perDRB;

[0112] 2.EARLYFORWARDINGTRANSFER with "First DL COUNT";

[0113] 3. Continue UL / DL data transmission / reception in source cell while establishing a new connection in the target cell;

[0114] 4. Data forwarding of DL data;

[0115] 5. Buffer DL data;

[0116] 6. Random Access procedure;

[0117] 7. Switch UL data transmission from source to target cell. Continue DL data reception in source cell.

[0118] See also Figure 2 , the specific steps are as follows:

[0119] 1. Handover Complete + Packet Data Convergence Protocol (PDCP) status report (status Report);

[0120] 2. Perform UL transmission in the target cell. Perform DL reception in the source cell and the target cell (UL transmission in target cell. DL reception in source and target cell);

[0121] 3. Perform duplication check and start sending DL data to UE;

[0122] 4. Handover success;

[0123] 5. Path switch request;

[0124] 6. Stop sending / receiving data to / from UE;

[0125] 7.SN STATUS TRANSFER;

[0126] 8. RRCReconfigure / RRC Connection Reconfiguration with “daps-sourceRelease”;

[0127] 9.RRC Reconfiguration Complete / RRC Connection Reconfiguration Complete+PDCP Status Report (RRCReconfigureComplete / RRC Connection Reconfiguration Complete+PDCP Status Report);

[0128] 10.UE context release (UE context Release);

[0129] 11. Release of UE;

[0130] 12. Release connection to source cell. UL transmission and DL reception only in target cell.

[0131] During the DAPS handover process, the UE may experience a Radio Link Failure (RLF) or handover failure in four stages:

[0132] Phase 1: The UE has not received the DAPS handover command and RLF occurs in the source cell;

[0133] Phase 2: The UE executes the DAPS handover command but has not yet successfully accessed the target cell, such as when a random access failure occurs in the target cell;

[0134] Phase 3: The UE successfully accesses the target cell, but has not received a handover success indication from the target cell or target base station, such as a daps-sourceRelease message, and the UE experiences RLF in the source cell or the target cell or in both cells at the same time.

[0135] Phase 4: DAPS handover is completed and the UE experiences RLF in the target cell;

[0136] For phases 1, 2 and 4, according to the prior art, the UE will generate an RLF report, recording the identity (ID) and measurement results of the source cell and neighbor / target cell when RLF or handover failure occurs, the UE's location information, the UE's cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI) in the source cell, the UE's reconstructed cell ID, the length of time from the start of the handover to the connection failure, the length of time from the connection failure to the UE successfully entering the connected state again, and other information.

[0137] As for stage 3, the RLF of the source cell during this period may be caused by the source base station configuring the DAPS switching too late, or by the target base station sending the daps-sourceRelease message too late; and, since the UE's RRC connection in the target cell has not failed (failure) and the UE does not reestablish, then according to the prior art, the UE will not record the RLF of the source cell. The RLF of the target cell during this period may be caused by the source base station configuring the DAPS switching too early. If RLF occurs in two cells (this situation will not occur in the prior art because the UE is only connected to one cell at a time), it may be caused by poor coverage at the UE's location or the selection of the wrong target cell. Since the UE maintains connection with both the source cell and the target cell in stage 3, the UE can or needs to record information related to the source and target cells to help the source base station and the target base station on the network side find the cause of the failure and help optimize the subsequent DAPS switching configuration process.

[0143] See also Figure 4 The embodiment of the present application provides a method for optimizing configuration. The execution subject of the method may be a network side device. The specific steps include: step 401 and step 402.

[0144] Step 401: Receive first information, where the first information indicates information related to DAPS switching failure or success;

[0145] The first information includes one or more of the following:

[0146] (1) The current state of the terminal;

[0147] Optionally, the current state of the terminal includes one or more of the following:

[0148] (a) Random access to the target cell is successful or an RRC connection is established, but no handover success indication is received from the target cell or target base station;

[0149] In the embodiment of the present application, the switching success indication may be a daps-sourceRelease message or a switching success message.

[0150] (b) DAPS switching is successful;

[0151] (c) receiving a handover success indication sent by a target cell or a target base station.

[0152] (2) The identifier of the cell where the DAPS failure occurred in the terminal;

[0153] Optionally, the identifier of the cell where the DAPS failure of the terminal occurs includes one or more of the following: an identifier of a source cell and an identifier of a target cell.

[0154] (3) C-RNTI used by the terminal in the source cell and / or target cell;

[0155] (4) The ID of the data radio bearer (DRB) or multicast radio bearer (MRB) to which the terminal currently performs DAPS switching;

[0156] (5) downlink user interruption time corresponding to the DRB ID;

[0157] For example, the duration of downlink IP packets or PDCP throughput being lower than a certain threshold (in order to verify the effect of DAPS, the purpose of DAPS is to reduce the user plane interruption delay).

[0158] (6) the length of time between the terminal completing RRC connection establishment in the target cell and receiving a daps-sourceRelease message sent by the target cell or target base station;

[0159] (7) measurement results of the serving cell, target cell and / or neighboring cell measured by the terminal;

[0160] (8) Location information of the terminal.

[0161] In an implementation manner of the present application, the method may further include: optimizing the DAPS switching configuration according to the first information.

[0162] In one implementation of the present application, the step of receiving the first information includes:

[0163] receiving a first message, wherein the first message includes the first information;

[0164] The first message is one of the following:

[0165] (1) Reconstruction request message;

[0166] (2) Radio Link Failure Report (RLF Report);

[0167] (3) logged MDT messages;

[0168] (4) Newly defined messages.

[0169] Exemplarily, after entering the connected state, the UE reports the first information through a newly defined message.

[0170] In an implementation manner of the present application, the first information is information recorded when a DAPS switching failure occurs in the terminal.

[0171] In an implementation manner of the present application, the DAPS handover failure includes: a source cell radio link failure and / or a target cell radio link failure.

[0172] In one implementation of the present application, the step of optimizing the DAPS switching configuration according to the first information includes one of the following methods:

[0173] Mode 1: Optimizing the timing of DAPS switching according to the current state of the terminal, the identifier of the cell where the DAPS failure occurs, and one or more of the measurement results of the serving cell, the target cell and / or the neighboring cell measured by the terminal;

[0174] Exemplarily, based on the current state of the UE, the identifier of the cell where the failure occurred, and measurement results and other information, the network side can determine whether the timing of configuring DAPS HO is appropriate. If RLF of the source cell occurs in stage 3, it may be that the source base station configured DAPS switching too late, and DAPSHO should be configured in advance subsequently; it may also be caused by the target base station sending the daps-sourceRelease message too late, and the target base station should send the message in advance; RLF of the target cell during this period may be caused by the source base station configuring DAPS switching too early, and it should be postponed subsequently. If RLF of two cells occurs, it may be caused by poor coverage of the UE's location or the selection of the wrong target cell. The coverage should be strengthened or the source base station should select a suitable target cell.

[0175] Mode 2: According to the time length between the terminal completing the RRC connection establishment in the target cell and receiving the daps-sourceRelease message sent by the target cell or the target base station, the measurement results of the serving cell, the target cell and / or the neighboring cell measured by the terminal, and one or more of the C-RNTIs used by the terminal in the source cell and / or the target cell, the time for sending the daps-sourceRelease message is optimized, or the signaling interaction process for successful switching between the target cell and the source cell is optimized, or the signaling interaction process of SNSTATUS TRANSFER between the target cell and the source cell is optimized;

[0176] Exemplarily, based on the length of time between the UE completing the RRC connection establishment in the target cell (such as the UE sending an RRC reconfiguration completion message to the target base station) and receiving the daps-sourceRelease message, as well as the measurement results of the source cell and the target cell measured by the UE, the C-RNTI of the UE in the source cell and the target cell, the source base station and the target base station can determine whether there is a risk of connection failure in the source cell or the target cell although the UE DAPS HO is successful; if so, the target base station should consider sending the daps-sourceRelease message in advance, or speeding up the signaling interaction process such as the switching success and SN statustransfer between the target base station and the source base station.

[0177] Method 3: Optimize the DAPS switching configured by the DRB according to the ID of the DRB on which the terminal currently performs DAPS switching, the downlink user interruption time corresponding to the ID of the DRB, the location information of the terminal, and one or more of the measurement results of the service cell, target cell and / or neighboring cell measured by the terminal.

[0178] For example, since DAPS is configured per DRB, the source base station can determine whether it is appropriate to configure DAPS HO for a certain DRB of the UE based on the ID of the DRB or MRB, the corresponding downlink user plane interruption time, the location of the UE, the measurement result and other information. If the downlink user plane interruption time is long, it means that the effect of DAPS HO is not very good, and the DRB of the UE at this location will not be configured with DAPS switching subsequently.

[0179] In an embodiment of the present application, the network side device may obtain information related to DAPS switching failure or success reported by the UE, and the network side device may further optimize the DAPS switching configuration according to the information related to DAPS switching failure or success.

[0181] Step 501: reporting first information to a network side device, where the first information indicates information related to DAPS switching failure or success;

[0182] The first information is used by the network side device to optimize the DAPS switching configuration.

[0183] The first information includes one or more of the following:

[0184] (1) The current state of the terminal;

[0185] (2) The identifier of the cell where the DAPS failure occurred in the terminal;

[0186] (3) C-RNTI used by the terminal in the source cell and / or target cell;

[0187] (4) The ID of the DRB or MRB to which the terminal currently performs DAPS switching;
