Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for processing cell handover failure, and a user equipment.
Background
In the version 38.331R16, Conditional Handover (Conditional Handover) and Conditional Primary and Secondary Cell Change (Conditional Primary Secondary Cell Change) are introduced as optimizations for mobility enhancement.
In the condition switching, a service cell in a connection state can configure a series of measurement, switching conditions and related channel configuration of adjacent cells, and when the measurement result of a certain adjacent cell meets the switching conditions, the channel configuration corresponding to the previous cell can be directly applied to directly switch to a target cell without sending a measurement report and waiting for a network switching instruction.
Similar to the conditional handover, the conditional primary and Secondary cell handover refers to configuring measurement, handover conditions and related channel configurations of a series of SN (Secondary Node) candidate cells through an MN (Master Node) under EN-DC (E-UTRA-NR Dual Connectivity, evolved universal terrestrial radio access and new air interface Dual Connectivity) Dual Connectivity, and when a measurement result of a certain adjacent SN cell satisfies the handover conditions, directly applying the channel configuration corresponding to the previous SN cell, and directly handing over to a target SN cell without sending a measurement report and waiting for a network handover instruction.
If the conditional handover or the conditional primary and secondary cell handover fails, the following scenarios may occur:
1. when the network just configures the condition switching or the condition primary and secondary cell switching fails, or the condition switching or the condition primary and secondary cell switching is about to be carried out, parameter check is carried out on the target cell channel configuration, and the UE capability is found not to be matched, so that the switching cannot be carried out, and the switching failure is caused.
2. The target cell may be handed over but the handover fails (synchronization or access failure).
For the condition switching, after the failure occurs, the UE may select a new cell to initiate the reestablishment, and select a reason for the reestablishment failure. However, different from the handover procedure initiated by the network, the failure caused by the conditional handover or the conditional primary and secondary cell handover now is that the network does not know the time for initiating the reestablishment and the target cell, and the UE only informs the network of the previous cause value, which may cause the network to continue to allocate the wrong configuration information to the UE, and further cause the UE to reestablish continuously, resulting in more handover failures.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for processing cell handover failure, where the method is applied to a user equipment, and as shown in fig. 1, the method includes:
and S11, after the cell switching fails, acquiring the reason of the switching failure and the information of the target cell of the switching failure.
S12, reporting the reason of the switching failure and the information of the target cell of the switching failure to the network side.
According to the cell handover failure processing method provided by the embodiment of the invention, after cell handover failure, the UE informs the network side of the target cell information of cell handover and the handover failure reason thereof, so that the network side can inform the corresponding adjacent cell base station of the failure reason, further optimization is carried out, and more handover failures are avoided.
The method for handling cell handover failure according to the present invention is described in detail below with reference to specific embodiments.
(1) Handling after conditional switch failure
The first scheme is as follows:
as shown in fig. 2, after the conditional handover fails, the UE sends an RRC reestablishment request message rrcreestablebluementrequest to the network side device, where in a reseestableshmentcause in the rrcreetablestablestagerequest, according to a specific reason of the handover failure, a cause value reconfigurationFailure or handoverFailure of the handover failure is carried, where,
reconfigurationFailure: for the case where the UE cannot support the target cell configuration;
hand over failure: the method is used for configuring the conditions of no abnormity but synchronization failure, access failure and the like in the switching process.
For failed configuration check, the UE may reestablish after receiving the reconfiguration with conditional handover from the beginning, or reestablish when actually preparing handover, and if the UE employs the first implementation manner, the UE may not be configured in a target cell with multiple conditional handovers, so the UE may report multiple target cells with failed handover.
After receiving an RRC reestablishment message rrcreestablshment sent by the network side device, the UE sends an RRC reestablishment complete message rrcreestablshment complete to the network side device, where in rrcreetastablishment complete-v16x0-IEs, a consinfiguration failurelist-r16 is carried, which is a cell information list with a length of maxnrofconsignals-r 16, and is the same as a network configured consigntoaddmodlist with a length, where each network configured consigntoaddmodlist has at most one cell failure information report.
Wherein, in the cell information list CondReconfigFailureList-r16, each cell information includes three parameters:
condReconfigId-r 16: corresponding to the configuration id of the network in CondReconfigToAddModList;
ssbFrequency: a cell SSB (Synchronization Signal Block) central frequency point;
phySCellId: cell PCI (Physical Cell Identifier).
Physcellld is optional because the UE may start checking the configuration in the UE for content that the UE does not support upon receiving a conditional handover re-assignment, at which point the target cell has not been actually measured.
After receiving the information reported by the UE, the network can send the failure reason to the corresponding adjacent cell base station, so as to optimize and avoid causing more switching failures.
Scheme II:
as shown in fig. 2, after the conditional handover fails, the UE sends an RRC reestablishment request message rrcreestablemarginrequest to the network side device, where in a reseestablesharmentcause in the rrcreestablemarginrequest, a cause value condReconfigFailure-r16 of the handover failure is carried, and in any case, the cause value is reported.
After receiving the RRC reestablishment message rrcreestablshment sent by the network side device, the UE sends an RRC reestablishment complete message rrcreestablshment complete to the network side device, and in rrcreetablshment complete-v16x0-IEs in rrcreetablshment complete, carries condensatfailurelist-r 16, which is a cell information list with a length of maxnrofconsiella-r 16, and has the same length as the network configured condresigtoadmodlist.
Wherein, in the cell information list CondReconfigFailureList-r16, each cell information includes four parameters:
condReconfigId-r 16: the configuration id of the network in CondReconfigugToAddModList corresponds to;
condReconfigugFailureCase: the specific failure reasons are represented and divided into two types, namely configuration failure and synchronous access switching failure, the failure reasons are bound with each cell, and a plurality of cells can fail due to different reasons, such as: cell A is failed in configuration, and cell B is failed in the switching synchronous access process;
ssbFrequency: a cell SSB center frequency point;
phySCellId: the cell PCI.
After receiving the information reported by the UE, the network can send the failure reason to the corresponding adjacent cell base station, so as to optimize and avoid causing more switching failures.
(2) Handling after conditional primary and secondary cell handover failure
The first scheme is as follows:
as shown in fig. 3, after the conditional primary and secondary cells fail to switch and perform RRC reconfiguration, the UE sends an SCG failure message SCGFailureInformation to the network side device, and carries a cause value SCG-reconfigfatile or synchrefinginfigures escg of the handover failure according to a specific cause of the handover failure in a failureType in the SCGFailureInformation, wherein,
scg-ReconfigFailure: for the case that the UE cannot support the target Primary and Secondary Cell (PSCell) configuration;
synchReconfigur Failure SCG; the method is used for configuring the conditions of synchronization failure, access failure and the like in the switching process of the primary cell and the secondary cell without abnormity.
Meanwhile, in the SCGFailureInformation, a field of condreconfigtfailurelist-r 16 is carried, which is a cell information list, and the length of the field is maxNrofCondCells-r16, and is the same as the length of network configured condreconfigtoadmodlist, wherein each network configured unit of condreconfigttoaddmodlist has at most one cell failure information report.
Wherein, in the cell information list CondReconfigFailureList-r16, each cell information includes three parameters:
condReconfigId-r 16: corresponding to the configuration id of the network in CondReconfigToAddModList;
ssbFrequency: a cell SSB center frequency point;
phySCellId: the cell PCI.
Physcellld is optional because the UE may start checking the configuration in the UE for content that the UE does not support upon receiving a conditional handover re-assignment, at which point the target cell has not been actually measured.
After receiving the information reported by the UE, the network can send the failure reason to the corresponding SN adjacent cell base station, so as to optimize and avoid causing more failures.
Scheme two
As shown in fig. 3, after the conditional primary and secondary cells fail to switch and perform RRC reconfiguration, the UE sends an SCG failure message SCGFailureInformation to the network side device, carries a cause value condreconfigfail-r 16 of the switching failure in the failureType-v1610 in the SCGFailureInformation, and reports the cause value for any conditional primary and secondary cell switching failure.
Meanwhile, in the SCGFailureInformation, there is carried CondReconfigFailureList-r16, which is a cell information list, having a length of maxNrofCondCells-r16, and the same length as that of network-configured condreconfigtoadmodlist.
Wherein, in the cell information list CondReconfigFailureList-r16, each cell information includes four parameters:
condReconfigId-r 16: the configuration id of the network in CondReconfigugToAddModList corresponds to;
condReconfigugFailureCase: the specific failure reasons are represented and divided into two types, namely configuration failure and synchronous access switching failure, the failure reasons are bound with each cell, and a plurality of cells can fail due to different reasons, such as: cell A is failed in configuration, and cell B is failed in the switching synchronous access process;
ssbFrequency: a cell SSB center frequency point;
phySCellId: the cell PCI.
