Detailed Description

DAPS is a mechanism introduced to reduce user plane latency during handover. As shown in fig. 1 and fig. 2, after receiving a handover command, a terminal (e.g., User Equipment (UE)) initiates a random access procedure to a target base station, during which uplink and downlink data transmission with a source base station may not be interrupted; the UE does not discontinue the data transmission process with the source base station until receiving the explicit notification of the target base station. After the UE successfully completes Radio Resource Control (RRC) connection establishment in the target cell, signaling interaction processes such as successful handover, secondary node state transfer (SN status transfer) and the like are performed between the target cell and the source cell, and then a subsequent path switch (path switch) process is performed.

Referring to fig. 1, the specific steps are as follows:

1.Handover Command with“daps-HO”/“dapsConfig”perDRB；

2.EARLYFORWARDINGTRANSFER with“First DL COUNT”；

3. while establishing a new connection in the target cell, continuing to transmit/receive (content UL/DL data transmission/reception in source cell) UL/DL data in the target cell;

4. downstream Data forwarding (Data forwarding of DL Data);

5. buffering downlink data (Buffer DL data);

6. a Random Access procedure (Random Access procedure);

7. the UL data transmission is handed over from the source cell to the target cell. DL data reception in source cell continues in the source cell (Switch UL data transmission from source to target cell.

Referring to fig. 2, the specific steps are as follows:

1. handover Complete (Handover Complete) + Packet Data Convergence Protocol (PDCP) status Report (status Report);

2. UL transmissions are made in the target cell. DL reception in source and target cells;

3. performing duplicate checking and starting to send DL data to the ue (performance duplication check and starting sending DL data to ue);

4. handover success (Handover success);

5. a Path switch request (Path switch request);

6. stopping transmitting/receiving data to/from the UE (stop transmitting/receiving data to/from the UE);

7.SN STATUS TRANSFER；

8. RRC Reconfiguration/RRC Connection Reconfiguration (RRC Reconfiguration/RRC Connection Reconfiguration with "daps-sourceRelease") using "daps-sourceRelease";

RRC Reconfiguration Complete/RRC Connection Reconfiguration Complete + PDCP Status Report (rrcconfigure Complete/RRC Connection Reconfiguration Complete + PDCP Status Report);

UE context Release (UE context Release);

11. release ue (release of ue);

12. the connection to the source cell is released. UL transmission and DL reception in the target cell only.

During the DAPS handover, the UE may have Radio Link Failure (RLF) or handover Failure in four stages:

stage 1: the UE does not receive the DAPS switching command and generates RLF in the source cell;

and (2) stage: the UE executes the DAPS handover command, but has not successfully accessed the target cell, such as the random access failure occurs in the target cell;

and (3) stage: the UE successfully accesses to the target cell, but does not receive a handover success indication sent by the target cell or the target base station, such as a data-source release (daps-source release) message, and the UE generates RLF in the source cell or the target cell or two cells at the same time;

and (4) stage: after the DAPS handover is completed, the UE generates RLF in the target cell;

for the stages 1, 2 and 4, according to the prior art, the UE may generate an RLF report, and record information such as Identifiers (IDs) and measurement results of a source Cell and a neighbor/target Cell when RLF occurs or handover fails, location information of the UE, a Cell-Radio Network Temporary Identifier (C-RNTI) of the UE in the source Cell, a Cell ID reconstructed by the UE, a time length from a handover start to a connection failure, and a time length from a connection failure to a time when the UE successfully enters a connected state again.

For phase 3, the RLF of the source cell during this period may be caused by the source base station configuring the DAPS handover too late, or the target base station sending the DAPS-sourceRelease message too late; moreover, since the RRC connection of the UE in the target cell does not fail (failure), and the UE does not perform reestablishment, the UE does not record the RLF of the source cell according to the prior art. The RLF of the target cell may occur during this time due to the source base station prematurely configuring the DAPS handover. If RLFs for two cells occur (as is not the case in the prior art because the UE is connected to only one cell at a time), this may be due to poor coverage at the location of the UE or selection of the wrong target cell. Since the UE keeps connected to the source cell and the target cell at the same time in stage 3, the UE may or need to record information related to the source cell and the target cell, help the network side source base station and the target base station to find the reason of failure, and help optimize the subsequent DAPS handover configuration process.

Referring to fig. 4, an embodiment of the present application provides a method for optimizing configuration, where an execution subject of the method may be a network side device, and the method includes the specific steps of: step 401 and step 402.

Step 401: receiving first information, wherein the first information represents information related to DAPS handover failure or success;

wherein the first information comprises one or more of:

(1) the current state of the terminal;

(a) the random access in the target cell is successful or the RRC connection is established, and the switching success indication sent by the target cell or the target base station is not received;

in the embodiment of the present application, the handover success indication may be a daps-sourceRelease message or a handover success message.

(b) The DAPS handover is successful;

(c) and receiving a switching success indication sent by the target cell or the target base station.

(2) The terminal generates the identification of the cell with DAPS failure;

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

(4) an ID of a Data Radio Bearer (DRB) or a Multicast Radio Bearer (MRB) for which the terminal currently performs the DAPS handover;

(5) the downlink user interruption time corresponding to the ID of the DRB;

for example, the duration of the downlink IP packet or PDCP throughput is below a certain threshold (in order to verify the effect of the DAPS, the purpose of the DAPS is to reduce the user plane interruption delay).

(6) The terminal completes the time length between the establishment of RRC connection in the target cell and the reception of the daps-sourceRelease message sent by the target cell or the target base station;

(7) the measurement results of the serving cell, the target cell and/or the neighbor cell measured by the terminal;

(8) location information of the terminal.

In one embodiment of the present application, the method may further include: and optimizing the DAPS switching configuration according to the first information.

In one embodiment of the present application, the step of receiving the first information includes:

wherein the first message is one of:

(1) a reestablishment request message;

(2) radio link failure Report (RLF Report);

(3) logged minimization of drive tests (logged MDT) messages;

(4) a newly defined message.

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

In one embodiment of the present application, the first information is information recorded when the DAPS handover failure occurs in the terminal.

In an embodiment of the present application, the DAPS handover failure includes: a source cell radio link failure and/or a target cell radio link failure.

In an embodiment of the application, the step of performing optimization processing on the DAPS handover configuration according to the first information includes one of the following manners:

mode 1: optimizing the DAPS switching time according to the current state of the terminal, the identification of the cell in which the terminal fails DAPS and one or more measurement results of a serving cell, a target cell and/or a neighboring cell measured by the terminal;

illustratively, according to the current state of the UE, the identity of the cell where failure occurs, and information such as measurement results, the network side may determine whether the time for configuring the DAPS HO is appropriate. If RLF of the source cell occurs in stage 3, it may be that the source base station configures DAPS handover too late, and then configures DAPS ho in advance; or the target base station sends the daps-sourceRelease message too late, and the target base station should send the message in advance; the occurrence of RLF of the target cell during this period may be due to the source base station prematurely configuring the DAPS handover and should be postponed later. If RLF of two cells occurs, which may be caused by poor coverage of the UE location or wrong target cell selection, coverage should be enhanced subsequently or the source base station should select the appropriate target cell.

Mode 2: optimizing the time for sending the daps-sourceRelease message, or optimizing the signaling interaction process of successful handover between the target cell and the source cell, or optimizing the signaling interaction process of SN STATUS TRANSFER between the target cell and the source cell according to the time length between the time for the terminal to complete RRC connection establishment in the target cell and receive the daps-sourceRelease message sent by the target cell or the target base station, the measurement result of the serving cell, the target cell and/or the neighboring cell measured by the terminal, and one or more C-RNTIs used by the terminal in the source cell and/or the target cell;

illustratively, according to the time length between the UE completing RRC connection establishment in the target cell (e.g., the UE sending an RRC reconfiguration complete message to the target base station) and receiving the DAPS-sourceRelease message, and the measurement results of the source cell and the target cell measured by the UE, the UE is at the C-RNTIs of the source cell and the target cell, and the source base station and the target base station may determine whether there is a risk of connection failure in the source cell or the target cell although the DAPS HO of the UE is successful; if so, the target base station should consider sending the daps-sourceRelease message in advance, or accelerating the successful switching between the target base station and the source base station, and signaling interaction processes such as SN status transfer.

Mode 3: and optimizing the DAPS handover configured by the DRB according to the ID of the DRB currently executing the DAPS handover by the terminal, the downlink user interruption time corresponding to the ID of the DRB, the position information of the terminal and one or more measurement results of a serving cell, a target cell and/or a neighboring cell measured by the terminal.

For example, since the DAPS is configured by per DRB, the source base station may determine whether it is appropriate to configure the DAPS HO to a certain DRB of the UE according to the ID of the DRB or MRB, and information such as corresponding downlink user plane interruption time, location of the UE, and measurement result. If the downlink user plane interruption time is long, it indicates that the DAPS HO effect is not good, and the DRB for the UE at the location is not configured with DAPS handover.
