To facilitate a better understanding of embodiments of the present application, DAPS handoff related to the present application will be described.

In The third generation partnership project (The 3rd Generation Partnership Project,3GPP) mobility enhancement topics (including LTE and NR), DAPS optimization methods for reducing interruption time at handover are proposed, the main idea being that The UE will maintain The protocol stacks of both The source and target cells during handover. And after receiving the DAPS switching command, the UE keeps the connection of the source cell and initiates a synchronization process to the target cell. When the synchronization process/random access is completed, the UE performs uplink data switching, that is, uplink data transmission of the UE after random access is switched from the source base station side to the target base station side. The release of the source base station protocol stack after the random access is based on the explicit indication of the network, that is, the UE can normally receive the downlink data sent by the source cell and can send uplink feedback related information of the downlink data to the source cell during the period from the random access to the release of the source connection.

During the random access of the UE to the target cell, the UE can keep monitoring the radio link of the source cell, if the DAPS handover fails at this time, the UE does not successfully access the target cell, and the radio link failure does not occur in the source cell, the UE can return to the connection with the source cell, thereby avoiding the reestablishment process of the radio resource control (Radio Resource Control, RRC) connection caused by the handover failure.

As shown in fig. 2 in particular, DAPS handoff may be accomplished by the following steps S1 to S16.

S1, an access and mobility management function (Access and Mobility Management Function, AMF) entity provides mobile control information;

s2, measuring and reporting;

s3, determining switching by a source gNB;

s4, the source gNB sends a switching request to the target gNB;

s5, performing admission control by the target gNB;

s6, the target gNB sends a switching request Acknowledgement (ACK) to the source gNB;

s7, the source gNB sends a DAPS switching command to the UE;

s8, the source gNB sends Sequence Number (SN) state migration to the target gNB;

s9, establishing connection with a target gNB through random access;

s10, the UE sends RRC reconfiguration completion information to the target gNB;

s11, the target gNB sends a DAPS source release (DAPS-sourceRelease) message to the UE;

S12, the UE sends a source cell release message to a source gNB;

s13, the target gNB sends a path switching request to an AMF entity;

s14. path switching in the user plane function (User Plane Function, UPF) entity;

s15, the AMF entity sends a path switching request confirmation to the target gNB;

s16, the target gNB sends a UE context release message to the source gNB.

As can be seen from fig. 2 above, the daps-sourcererelease is sent to the UE by the target gNB after the handover is completed, to inform the UE that the connection with the source gNB can be released.

To facilitate a better understanding of embodiments of the present application, the premature handover associated with the present application will be described. As shown in fig. 3, the premature handoff may include at least some of the following:

the terminal generates a radio link failure (Radio Link Failure, RLF) on the target base station after the switching failure occurs or the switching success is completed in the process of accessing the target base station;

the terminal selects a source cell after a cell selection process, and initiates a reconstruction process;

after the reconstruction is completed, the terminal sends an RLF report to the source base station;

the source base station finds that this is a problem for premature handover (judgment reason: 1. Timer reported by the terminal is less than configured threshold and first re-establishment attempt cell is the cell serving the terminal at the last handover initialization or the cell the terminal tries to reconnect is the cell serving the terminal at the last handover initialization; 2. Failed primary cell identity (failledPCellID) in RLF report is set to ID of source cell, connection failure type (connectionFailureType) value is set to 'hof', or ID, connectionFailureType value of failledPCellID is set to 'rlf');

The source base station changes the threshold setting of the measurement target corresponding to the terminal measurement report event.

In order to better understand the embodiment of the present application, the process of reporting RLF report by the terminal related to the present application is described.

After the timer 304 (T304) expires, the terminal may store an RLF report related to handover failure (HOF) or after the terminal successfully accesses the target cell, the terminal may generate RLF in the target cell due to the timer (T310) expires and so on. After that, the terminal initiates a reestablishment process towards a certain cell, and after reestablishment or RRC connection establishment is completed, the terminal sends a relevant RLF report of last HOF failure to the reestablished cell:

1. the terminal carries the available RLF information (RLF-infoassable) in an RRC signaling such as message5 (msg 5) RRC reestablishment complete (rrcreesctable complete) message to inform the network that the terminal has radio link failure or handover failure information in the variable RLF Report (varRLF-Report).

2. If the network needs the terminal to report, the network sends RRC to the terminal: terminal information request (ueinfo request) signaling with RLF report request (RLF-ReportReq) set to true.

3. The terminal reports RRC: a terminal information response (UEinformationResponse) is signaled to the network, wherein rlf-Report is set to the value stored in the terminal variable varRLF-Report.

To facilitate a better understanding of the embodiments of the present application, the information blocks contained in the RLF report related to the present application are described.

1. Reference signal received power (Reference Signal Received Power, RSRP), reference signal received quality (Reference Signal Received Quality, RSRQ) and signal-to-interference-and-noise ratio (Signal to Interference plus Noise Ratio, SINR) of the derived source cell are measured based on available synchronization signal blocks (Synchronization Signal Block, SSB) and channel state information reference signals (Channel State Information Reference Signal, CSI-RS) obtained before the UE discovers RLF: the measurement result (measResultLastServCell) of the last serving cell;

2. signal measurement results of neighbor cells (the neighbor cells with good signals and measurement results thereof are placed in front of the menu list);

3. geographical location information when RLF occurs;

target cell ID when hof occurs;

5. connection failure time (timecon failure) the time between when the last Handover (HO) occurred and connection failure (timer (UE reported timer) reported by the terminal);

6. a reconnection cell ID (source cell ID);

7. a previous primary cell identity (previouspelellid) (source cell ID);

8. The connection failure type is set to hof (handover failure).

To facilitate a better understanding of embodiments of the present application, the A3 event associated with the present application will be described.

When the following A3-1 condition is satisfied, the terminal considers that an A3 event is entered; the terminal considers to leave the A3 event when the following A3-2 condition is satisfied. Among them, mp, ofp, and Ocp use Special cells (SpCell).

hys is a hysteresis parameter of the A3 event (e.g., a hysteresis parameter defined in NR configuration report (reportconfigNR) of the A3 event);

off is an offset parameter for the A3 event (e.g., an A3 offset defined in NR configuration report (reportConfigNR) for the A3 event);

mn and Mp are denoted by dBm in RSRP, mn and Mp are denoted by dB in RSRQ and SINR;

ofn, ocn, ofp, ocp, hys, off is expressed in dB.

To facilitate a better understanding of embodiments of the present application, the A5 event associated with the present application will be described.

When the following conditions A5-1 and A5-2 are satisfied at the same time, the terminal considers that an A5 event is entered; the terminal considers the leave A5 event when the following A5-3 or A5-4 condition is satisfied. Wherein, mp uses SpCell.

Inequality A5-1 (entry condition 1):

Mp+Hys<Thresh1。

inequality A5-2 (entry condition 2):

Mn+Ofn+Ocn–Hys>Thresh2。

Inequality A5-3 (leaving condition 1):

The representation of Thresh1 is consistent with Mp;

In order to facilitate a better understanding of the embodiments of the present application, technical problems existing in the prior art are described.

After the terminal is successfully switched to the target base station, under the condition that whether a DAPS source release message (DAPS-sourceRelease) is received or not is not reported, and under the condition that RLF occurs to the connection of the target base station, the network cannot know whether the threshold value in the A3 event or the A5 event which needs to be adjusted is large or small through an RLF report sent by the terminal.

Based on the above problems, the present application proposes an information reporting scheme, where a terminal device can report whether the terminal device receives information for indicating to release a source cell when RLF occurs between the terminal device and a target cell, so that a network device can more reasonably adjust a threshold value of a measurement reporting event, thereby ensuring effectiveness of subsequent DAPS switching configuration, and optimizing DAPS switching.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 4 is a schematic flow chart of a method 200 of information reporting according to an embodiment of the present application, as shown in fig. 4, the method 200 may include at least some of the following:

S210, the terminal equipment sends first information; the first information comprises first indication information, and the first indication information is used for indicating whether the terminal equipment receives information for indicating to release a source cell when RLF occurs between the terminal equipment and a target cell;

s220, the network equipment receives the first information sent by the terminal equipment.

In the embodiment of the application, the terminal equipment can report whether the terminal equipment receives the information for indicating to release the source cell when the RLF occurs between the terminal equipment and the target cell, so that the network equipment can more reasonably adjust the threshold value of the measurement reporting event, thereby ensuring the effectiveness of the subsequent switching configuration.

In some embodiments, embodiments of the application are applied to DAPS handoff. But of course may be applied to other types of cell handover, as the application is not limited in this regard.

In some embodiments, the information indicating the release source cell may be, for example, a DAPS source release message (DAPS-sourceRelease).

In some embodiments, the first information may be an RLF report, or the first information may be carried by an RLF report. For example, the terminal needs to add an identification to the RLF report indicating whether the network has received daps-release source when RLF occurs, so that the network knows whether the threshold needs to be adjusted to be large or small.

In some embodiments, the network device is the network device of the cell that re-establishes or reconnects after the DAPS handoff failure, or the network device is the network device of the source cell.

In some embodiments, the first information includes second indication information, and the second indication information is used to indicate speed information of the terminal device. Thus, the network is more aware of the magnitude of the amplitude the threshold needs to be adjusted.

In some implementations, the speed information of the terminal device is the speed of the terminal device. For example, the second indication information indicates that the speed of the terminal device is v ₀ I.e. the current movement speed of the terminal device is v ₀ 。

In some implementations, the speed information of the terminal device includes a level of the speed of the terminal device corresponding to at least two speed levels.

In some implementations, the at least two speed levels are pre-configured or agreed upon by the protocol, or the at least two speed levels are configured by the network device.

For example, the at least two speed classes include a low speed and a high speed.

As another example, the at least two speed classes include a low speed, a medium speed, and a high speed.

In some embodiments, the network device determines a threshold for a subsequent measurement reporting event according to the first information; and the network equipment sends second information to the terminal equipment, wherein the second information is used for indicating the threshold value of the subsequent measurement reporting event.

In some implementations, the threshold for the subsequent measurement reporting event is a threshold in the A3 event (e.g., parameter Off in the inequality A3-1 and/or A3-2 described above, or a parameter related to parameter Off), or the threshold for the subsequent measurement reporting event is a threshold in the A5 event (e.g., parameter Thresh1 in the inequality A5-1 and/or A5-3 described above, or parameter Thresh2 in the inequality A5-2 and/or A5-4 described above, or a parameter related to parameter Thresh1 and/or Thresh 2).

In some implementations, the network device determines a threshold for the subsequent measurement reporting event according to content indicated by the first indication information included in the first information.

That is, the network device may determine the threshold of the subsequent measurement reporting event according to whether the terminal device receives the information for indicating to release the source cell when RLF occurs between the terminal device and the target cell.

In some implementations, the threshold for the subsequent measurement reporting event satisfies:

when the first indication information indicates that RLF occurs between the terminal device and the target cell, and the terminal device receives information for indicating to release the source cell, a difference value of a threshold value of the subsequent measurement reporting event compared with a threshold value of the original measurement reporting event is larger than a first threshold value; and/or the number of the groups of groups,

And under the condition that the first indication information indicates that the terminal equipment does not receive the information for indicating to release the source cell when RLF occurs between the terminal equipment and the target cell, the difference value of the threshold value of the follow-up measurement report event compared with the threshold value of the original measurement report event is smaller than a first threshold value.

In some implementations, the first threshold is pre-configured or agreed upon by the protocol, or the first threshold is configured by the network device.

In some implementations, the network device determines the threshold for the subsequent measurement reporting event according to content indicated by the first indication information and/or content indicated by the second indication information included in the first information.

when the first indication information indicates that RLF occurs between the terminal device and the target cell, and the terminal device does not receive information for indicating to release the source cell, a difference value of a threshold value of the subsequent measurement reporting event compared with a threshold value of the original measurement reporting event is smaller than a first threshold value; and/or the number of the groups of groups,

When the second indication information indicates that the speed of the terminal equipment is smaller than a second threshold value, the difference value of the threshold value of the follow-up measurement reporting event compared with the threshold value of the original measurement reporting event is smaller than a third threshold value; and/or the number of the groups of groups,

when the second indication information indicates that the speed of the terminal equipment is greater than a second threshold value, the difference value of the threshold value of the follow-up measurement reporting event compared with the threshold value of the original measurement reporting event is greater than a third threshold value; and/or the number of the groups of groups,

when the first indication information indicates that the terminal equipment does not receive information for indicating to release the source cell when RLF occurs between the terminal equipment and the target cell, and the second indication information indicates that the speed of the terminal equipment is smaller than a second threshold, a difference value of the threshold value of the subsequent measurement reporting event compared with the threshold value of the original measurement reporting event is smaller than a fourth threshold value; and/or the number of the groups of groups,

when the first indication information indicates that RLF occurs between the terminal device and the target cell, the terminal device does not receive information for indicating to release the source cell, and when the second indication information indicates that the speed of the terminal device is greater than a second threshold, a difference value of the threshold value of the subsequent measurement reporting event compared with the threshold value of the original measurement reporting event is greater than a fourth threshold value; and/or the number of the groups of groups,

When the first indication information indicates that RLF occurs between the terminal device and the target cell, the terminal device receives information for indicating to release the source cell, and the second indication information indicates that the speed of the terminal device is smaller than a second threshold, a difference value between the threshold of the subsequent measurement reporting event and the threshold of the original measurement reporting event is smaller than a fifth threshold; and/or the number of the groups of groups,

when the first indication information indicates that RLF occurs between the terminal device and the target cell, the terminal device receives information for indicating to release the source cell, and when the second indication information indicates that the speed of the terminal device is greater than a second threshold, a difference between the threshold of the subsequent measurement reporting event and the threshold of the original measurement reporting event is greater than a fifth threshold.

In some implementations, some or all of the first to fifth thresholds are pre-configured or protocol agreed, or some or all of the first to fifth thresholds are network device configured.

As an example, as shown in fig. 5, corresponding to a premature handover (too early handover), measurements of cells when RLF occurs: the measurement result of the RSRP of the source cell is-70 dBm, and the measurement result of the RSRP of the target cell is-68 dBm. If the terminal device does not generate RLF for the target cell until it receives daps-sourcererelease (i.e. information indicating release of the source cell), it is stated that the location signal closer to the target cell is still unstable, and a greater degree of adjustment should be considered when setting the threshold for subsequent measurement reporting events. Otherwise, if the terminal device generates RLF for the target cell before receiving the daps-sourcererelease (i.e. the information for indicating the release source cell), it is indicated that the position signal is unstable only in the edge of the target cell, and only a small-amplitude adjustment is required to set the threshold value of the subsequent measurement reporting event.

For example, as shown in fig. 6, the terminal device generates RLF for the target cell before receiving the daps-sourcererelease (i.e. the information for indicating the release source cell), and the network device fine-tunes the threshold of the subsequent measurement reporting event, so that it is better to slightly shift the position of the terminal that triggers the measurement reporting to the right. Specifically, assume that the threshold value of the original measurement reporting event is the difference value (Off) of the A3 event, and Off is 3dB; then the network adjusts the difference (Off) of the A3 event to 5dB.

For another example, as shown in fig. 7, after receiving the daps-sourcererelease (i.e. the information for indicating the release source cell), the terminal device generates RLF for the target cell, and the network device needs to greatly adjust the threshold value of the subsequent measurement reporting event, so that the terminal position for triggering measurement reporting is closer to the position of the target base station. Specifically, assume that the threshold value of the original measurement reporting event is the difference value (Off) of the A3 event, and Off is 3dB; then the network adjusts the difference (Off) of the A3 event to 7dB.

As another example, as shown in fig. 8, the terminal device generates RLF for the target cell before receiving the daps-sourcererelease (i.e. the information for indicating the release source cell), and the speed class corresponding to the speed of the terminal device is high, and the network device fine-adjusts the threshold of the subsequent measurement reporting event, so that the position of the terminal triggering the measurement reporting is better to shift slightly to the right. Specifically, assume that the threshold value of the original measurement reporting event is the difference value (Off) of the A3 event, and Off is 3dB; then the network adjusts the difference (Off) of the A3 event to 6dB.

As another example, as shown in fig. 9, the terminal device generates RLF for the target cell before receiving the daps-sourcererelease (i.e. the information for indicating the release source cell), and the speed of the terminal device corresponds to a medium speed, and the network device fine-adjusts the threshold of the subsequent measurement reporting event, so that the position of the terminal triggering the measurement reporting is better to shift slightly to the right. Specifically, assume that the threshold value of the original measurement reporting event is the difference value (Off) of the A3 event, and Off is 3dB; the difference (Off) of the network adjust A3 event is 4dB.

In some embodiments, the first information is an RLF report, and the information used to indicate that the release source cell is daps-sourcererase, where the speed of the terminal device corresponds to a low speed or a medium speed or a high speed. Specifically, the RLF report reported by the terminal device may be as follows:

it should be noted that, in the above RLF Report (RLF-Report-r 16), other information than whether the daps source release (ifreceptionofpaps-release) and mobility state (mobility state) fields are received may be information in some existing standards, which is not described in detail in the present application.

Therefore, in the embodiment of the application, the terminal equipment can report whether the terminal equipment receives the information for indicating to release the source cell when the RLF occurs between the terminal equipment and the target cell, so that the network equipment can more reasonably adjust the threshold value of the measurement reporting event, thereby ensuring the effectiveness of the subsequent switching configuration.

According to the application, by reporting whether the terminal equipment receives the DAPS-sourceRelease signaling and optional reporting terminal mobile state information when the RLF facing the target cell occurs, the network equipment can more reasonably adjust the threshold value of the measurement reporting event so as to adjust the time point of switching occurrence, thereby reducing the possibility of the RLF occurrence of the terminal equipment in the DAPS switching process.
