Description

Failure processing method and device

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a failure processing method and a device thereof.

Background

In the related art, when performing selective activation of a cell group in a multi-radio dual-connection MR-DC, a terminal device needs to store or update the cell group selective activation configuration in a Var variable after receiving the cell group selective activation configuration. In order to reduce the time delay of selective activation of the preconfigured cell group, when the configuration information of the cell group to be activated is stored, the terminal equipment can read the configuration information in the Radio Resource Control (RRC) reconfiguration message and store the read configuration information, so that the time delay of activating the preconfigured cell group to be activated is reduced. However, the terminal device may not be able to correctly read the configuration information, e.g., the terminal device may not be able to follow some or all of the configuration information contained in the cell group. The behavior of the terminal device in the case of a pre-read failure is not specified in the related art. If the above situation is not handled, it may result in the occurrence of a cell group selective activation failure.

Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Wherein, in the description of the present disclosure, "/" means or is meant unless otherwise indicated, e.g., a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.

For ease of understanding, the terms referred to in this disclosure are first introduced.

1、MR-DC

MR-DC (Multi-Radio Dual Connectivity ) is a generalized Intra-E-UTRA (Evolved Universal Terrestrial Radio Access ) dual connectivity, and terminal devices can utilize radio resources provided by two different schedules located on two different NG (new radio,5G new air) -RAN (radio access network) nodes, one providing NR access and the other providing E-UTRA or NR access over non-ideal backhaul connections. One as MN (Master Node) and one as SN (Secondary Node). The MN and SN are connected by a network interface, at least one of which is connected to the core network.

2、MR-DC with EPC

The E-UTRAN supports MR-DC through E-UTRA-NR DC (EN-DC), in which terminal devices are connected to one eNB (evolved NodeB) serving as an MN and one EN-gNB (next generation NodeB, next generation base station) serving as an SN. The eNB is connected to EPC (Evolved Packet Core ) through an S1 interface and to en-gNB through an X2 interface. The en-gNB may also be connected to the EPC through the S1-U interface, and may also be connected to other en-gNBs through the X2-U interface.

3、MR-DC with 5GC

A)E-UTRA-NR Dual Connectivity NGEN-DC

The NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), where the terminal device is connected to one NG-eNB as MN and one gNB as SN. The ng-eNB is connected to a 5GC (5G core,5G core network) and the gNB is connected to the ng-eNB through an Xn interface.

B)NR-E-UTRA Dual Connectivity NE-DC

The NG-RAN supports NR-E-UTRA DC (NE-DC), where the terminal equipment is connected to one gNB acting as MN and one NG-eNB acting as SN. The gNB is connected to 5GC and the ng-eNB is connected to the gNB through an Xn interface.

4、NR-NR Dual Connectivity

The NG-RAN supports NR-NR DC (NR-DC), where the terminal device is connected to one gNB acting as MN and another gNB acting as SN. The main gNB is connected to the 5GC through an NG interface, the two gNBs are connected through an Xn interface, and the auxiliary gNB can also be connected to the 5GC through an NG-U interface. In addition, NR-DC can also be used for terminal device access to a single gNB, acting as both MN and SN, configuring MCG (Master Cell group, primary cell group) and SCG (Secondary Cell group ) simultaneously. Under dual connectivity, the terminal device can access two cell groups, MCG and SCG, respectively. Under MCG, there may be many cells, one of which is used to initiate an initial access, which is called PCell. As the name suggests, PCell is the most "primary" cell within MCG. The PCell under MCG and SCell under MCG are joined together by CA (Carrier Aggregation ). The main cell in the MCG is PCell, and the auxiliary cell is SCell; the primary and secondary cells in the SCG are PSCell, and the secondary cells are SCell. Since much signaling is only sent on PCell and PSCell, a concept of sPCell (specific Cell) is also defined in the protocol for descriptive convenience, and PCell and PSCell are collectively called sPCell.

5. Selective activation of cell groups:

in Rel-16 Conditional Handover (CHO) and in Rel-17 Conditional PSCell Change (CPC)/Conditional PSCell Addition (CPA), the terminal device of the CHO/CPC/CPA configuration has to release the CHO/CPC/CPA configuration when random access to the target PCell/PSCell is completed. Thus, if the network does not reconfigure and reinitialize the CHO/CPC/CPA, the terminal has no opportunity to subsequently continue to perform CHO/CPC/CPA. This will increase the delay of the handover or SCG change and increase the signal overhead, especially in the case of frequent CG (Cell group) changes in FR (Frequency Range) 2 scenarios. Thus, in the R18 mobility enhancement subject standpoint, a selective activation of the MR-DC cell group (selective activation of cell groups) is proposed that can enable subsequent CHO/CPC/CPA to be performed after CG changes without requiring network reconfiguration or reinitialization of CHO/CPC/CPA. This may reduce signaling overhead and the interrupt duration of CG change.

In selective activation of cell groups, the network device may provide the terminal device with preconfigured candidate target cell groups or target cells. The subsequent terminal device may activate or deactivate the preconfigured candidate cell group or cell according to the configuration (e.g., activation message) issued by the network device or the corresponding activation event without having to re-provide the configuration of the cell group. Or, in the selective activation of a cell group, a new cell or a cell group is activated, or after the new cell configuration or the cell group configuration is applied or after the new cell or the cell group is accessed, the terminal device will not delete the configuration information of the selective activation of the corresponding cell group.

The selective activation of a cell group (selective activation of cell groups), which may also be referred to as cell group activation. It may enable the cell group or cell change, the corresponding configuration information can still be performed without the need for network reconfiguration or reinitialization of the configuration information for the corresponding cell group activation. This may reduce signaling overhead and interrupt duration for cell group changes. The configuration information for cell group activation may include: configuration ID (identity, identification code) or configuration of the target cell group. Optionally, the configuration information of cell group activation may also include trigger conditions (which may also be referred to as execution conditions, activation conditions).

In the embodiment of the disclosure, the cell group activation is a mobility management procedure, which includes any mobility management procedure of activating or deactivating a corresponding cell or cell group by configuring cell group activation configuration, enabling a terminal device to activate or deactivate the corresponding cell or cell group according to signaling sent by a network or a criterion specified by a protocol, or enabling the terminal device to autonomously or the like, or after the corresponding cell configuration or cell group configuration is applied or accessing the cell or cell group.

In embodiments of the present disclosure, cell group activation is a mobility management procedure, including any mobility management procedure that does not delete or release a corresponding part or all of the configuration information after performing the mobility procedure. Wherein not deleting or releasing the corresponding partial or complete configuration information may also be referred to as retaining the corresponding partial or complete configuration information.

In the present disclosure, a cell group is one or more of a primary cell group (MCG) and a Secondary Cell Group (SCG). Wherein the MCG includes one or more of Primary cells (PCell) and Secondary cells (SCell). Wherein the SCG comprises one or more of primary and secondary cells (Primary Secondary Cell, PSCell), secondary cells (scells).

In the present disclosure, cell group selective activation may include cell selective activation or cell activation, e.g., one or more of PCell activation, PSCell activation, SCell activation.

It should be noted that, in this disclosure, the method provided in any embodiment may be performed alone or in combination with the possible implementation methods in other embodiments, and may also be performed in combination with any technical solution in the related art.

Referring to fig. 2, fig. 2 is a flow chart of a failure processing method according to an embodiment of the disclosure. The method is performed by a terminal device. As shown in fig. 2, the method may include, but is not limited to, the steps of:

step S201: and receiving configuration information of at least one cell or cell group sent by the network side equipment.

As an example, the terminal device receives configuration information of at least one cell sent by the network side device.

As another example, the terminal device receives configuration information of at least one cell group sent by the network side device. As can be seen from the above, the configuration information of the cell or the cell group refers to the configuration information of the cell or the configuration information of the cell group, and the specific meaning of other similar descriptions in the embodiments of the disclosure is the same as that described above, which is not repeated in the embodiments of the disclosure.

Step S202: and reading the configuration information.

For example, the terminal device reads parameters or fields in the configuration information.

Step S203: and determining that the configuration information is read failed.

Step S204: and executing a processing corresponding to the read failure.

In the embodiment of the present disclosure, a specific implementation manner of the terminal device executing the processing procedure corresponding to the reading failure may refer to any other embodiment of the present disclosure, which is not described herein again.

By implementing the embodiment of the disclosure, when the terminal equipment determines that the reading of the configuration information fails, the terminal equipment can execute the processing corresponding to the reading failure. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

In an implementation manner of the embodiment of the present disclosure, the configuration information of at least one cell or cell group may be included in the mobility configuration information, and as an example, please refer to fig. 3, fig. 3 is a flow chart of another failure processing method provided by the embodiment of the present disclosure. The method is performed by a terminal device. As shown in fig. 3, the method may include, but is not limited to, the steps of:

In an alternative implementation manner, the mobility configuration information includes mobility configuration parameters corresponding to at least one cell or cell group; the mobility configuration parameters of each cell or group of cells include configuration information of the corresponding cell or group of cells.

The method is performed by a terminal device. As shown in fig. 4, the method may include, but is not limited to, the steps of:

step S401: and receiving configuration information of at least one cell or cell group sent by the network side equipment.

In the embodiment of the present disclosure, step S401 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S402: and reading the configuration information.

In the embodiment of the present disclosure, step S402 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S403: and determining that the configuration information is read failed.

In the embodiment of the present disclosure, step S403 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S404: and ignoring configuration information of the first cell or cell group configured by the network side equipment.

For example, the terminal device ignores the content that cannot be complied with in the configuration information of the first cell or cell group configured by the network side device.

In an optional implementation manner, the foregoing configuration information of the first cell or cell group configured by the network side device is ignored, and includes at least one of the following: ignoring mobility configuration parameters corresponding to the first cell or cell group; deleting mobility configuration parameters corresponding to a first cell or a cell group stored in the terminal equipment; and prohibiting the terminal equipment from being triggered according to the mobility configuration parameters corresponding to the first cell or the cell group and accessing the first cell or the cell group.

In the embodiment of the present disclosure, the deleting the mobility configuration parameter corresponding to the first cell or the cell group stored in the terminal device may have a plurality of specific implementation manners according to specific situations.

As an example, taking mobility configuration information including trigger conditions and cell group configuration information as an example, if reading the cell group configuration information fails, the corresponding trigger conditions stored by the terminal device need to be deleted.

As another example, taking the example that the mobility configuration information includes a trigger condition and cell group configuration information, if reading the cell group configuration information fails, only the configuration information of the cell group stored by the terminal device may be deleted.

By implementing the embodiment of the disclosure, the terminal equipment can ignore the configuration information after confirming that the configuration information fails to be read. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

In an implementation manner of the embodiment of the present disclosure, after the configuration information fails to be read, the terminal device may continue to use the stored configuration information of the terminal device, as an example, please refer to fig. 5, and fig. 5 is a schematic flow chart of still another failure processing method provided by the embodiment of the present disclosure. The method is performed by a terminal device. As shown in fig. 5, the method may include, but is not limited to, the steps of:

In the embodiment of the present disclosure, step S503 may be implemented by any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S504: the stored configuration information of the terminal device is continued to be used.

For example, the terminal device determines that the reading of the configuration information fails, and continues to use the original configuration information stored by the terminal device.

In an alternative implementation manner, the continuing to use the configuration information stored by the terminal device may include: continuing to use mobility configuration parameters corresponding to the first cell or cell group stored by the terminal equipment; or, continuing to use the configuration information of the corresponding cell or cell group contained in the mobility configuration parameters, and updating other configuration information contained in the mobility configuration parameters.

As an example, when the terminal device continues to use the configuration information stored in the terminal device in the step of the processing procedure corresponding to the reading failure, in response to the mobility configuration parameter corresponding to the first cell or the cell group stored in the terminal device, the terminal device continues to use the mobility configuration parameter corresponding to the first cell or the cell group, and does not update the configuration information corresponding to the first cell or the cell group.

As another example, when the terminal device continues to use the original configuration information item in the step of executing the processing procedure corresponding to the reading failure, in response to the mobility configuration parameter corresponding to the first cell or cell group stored in the terminal device, the terminal device continues to use the configuration information of the corresponding cell or cell group included in the mobility configuration parameter, and updates other configuration information content included in the existing mobility configuration parameter.

By implementing the embodiment of the disclosure, when the terminal equipment determines that the reading of the configuration information fails, the original configuration information is continuously used for selectively activating the cell or the cell group. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

For example, the terminal device sends corresponding indication information to the network side device according to different situations of failure in reading the configuration information.

In an optional implementation manner, the indication information is used to inform the network side device that the terminal device fails to read the configuration information.

For example, when the terminal device performs the processing corresponding to the reading failure and sends the indication information item to the network side device sending the configuration information, the indication information is used to inform the network side device that the terminal device fails to read the configuration information.

Optionally, the indication information includes at least one of: the method comprises the steps of identifying a first cell or a cell group, configuring information of the first cell or the cell group, configuring information identification of the first cell or the cell group, mobility configuring parameters of the first cell or the cell group, identifying mobility configuring parameters of the first cell or the cell group and failure reasons.

In the embodiment of the present disclosure, the failure reason may be a reason that the terminal device fails to read the configuration information; alternatively, the failure cause may be a cause of a reconfiguration failure of the terminal device.

Optionally, the indication information is used for indicating the terminal device to ignore configuration information of the first cell or the cell group; and/or, the indication information is further used for indicating whether the terminal equipment continues to use the stored configuration information of the terminal equipment.

As yet another example, the above indication information is used to instruct the terminal device to ignore configuration information of the first cell or cell group; and, the above indication information is also used to indicate whether the terminal device continues to use the configuration information stored by the terminal device.

It should be noted that, in the disclosed embodiment, the indication information may be indicated by separate 1bit data from the data sent by the terminal device to the network side device.

Step S705: and receiving configuration information sent by the network side equipment.

In the embodiment of the disclosure, the configuration information is reconfigured by the network side device according to the indication information sent by the terminal device.

For example, the terminal device receives configuration information sent by the network side device, where the configuration information is reconfigured by the network side device according to the indication information sent by the terminal device.

By implementing the embodiment of the disclosure, the terminal equipment can send the indication information when determining that the reading of the configuration information fails, so as to receive the configuration information sent by the network side equipment, and make the terminal equipment perform selective activation of the cell or the cell group based on the configuration information, thereby avoiding the occurrence of selective activation failure of the cell or the cell group and improving the communication reliability.

In one implementation manner of the embodiment of the disclosure, before receiving the reconfiguration message sent by the network side device, the terminal device may determine the configuration information stored by the terminal device.

As an example, the terminal device determines that the reading of the configuration information fails, and when performing an operation of ignoring the configuration information of one or more cells or cell groups corresponding to the configuration information that fails to read before receiving the reconfiguration message sent by the network side device, determines the stored configuration information of the terminal device.

As another example, the terminal device determines that the reading of the configuration information fails, and determines the stored configuration information of the terminal device when the original configuration information is continuously used before the reconfiguration message sent by the network side device is received.

By implementing the embodiment of the disclosure, before receiving the network side reconfiguration message, the terminal device can determine whether the stored configuration information of the terminal device is valid, so that the terminal device can determine whether subsequent steps can be performed based on the stored configuration information. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

In an implementation manner of the embodiment of the present disclosure, when determining that the content of the configuration information is successfully read, the terminal device may store the read content in a preset variable, or update the content stored in the first variable according to the read content.

In an embodiment of the present disclosure, the preset variable may be a Var variable.

As an example, the terminal device stores the read content to the Var variable in response to successfully reading the content of the configuration information.

As another example, the terminal device updates the corresponding content stored in the first variable based on the read content in response to successfully reading the content of the configuration information.

It should be noted that, in the embodiment of the present disclosure, when the mobility configuration information includes mobility configuration parameters corresponding to a plurality of cells or cell groups, the network side device may send the mobility configuration parameters to the terminal device, so that the terminal device reads the mobility configuration parameters corresponding to the cells or cell groups in the mobility configuration parameters, thereby performing selective activation of the cells or cell groups according to the configuration information of the cells or cell groups in the mobility configuration parameters corresponding to the cells or cell groups; or, the network side device may send mobility configuration information to the terminal device, so that the terminal device updates the mobility configuration information stored in the terminal device according to the mobility configuration information.

By implementing the embodiment of the disclosure, the network side equipment can send the mobility configuration information to the terminal equipment, so that the terminal equipment can perform cell selective activation based on the configuration information. And the communication reliability is improved.

In an implementation manner of the embodiment of the present disclosure, the network side device may also be capable of receiving the indication information sent by the terminal device, as an example, please refer to fig. 10, and fig. 10 is a flowchart of still another failure processing method provided by the embodiment of the present disclosure.

In the embodiment of the present disclosure, step S1001 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S1002: and receiving the indication information sent by the terminal equipment.

In the embodiment of the present disclosure, the indication information is used to inform the network side device that the terminal device fails to read the configuration information or fails to reconfigure.

As an example, the network side device receives indication information sent by the terminal device, where the indication information is used to inform the network side device that the terminal device fails to read the configuration information.

As an example, the network side device receives indication information sent by the terminal device, where the indication information is used to inform the network side device that the reconfiguration of the terminal device fails.

In an implementation manner of the embodiment of the present disclosure, the network side device may also perform different subsequent flows based on the indication information sent by the receiving terminal device, as an example, please refer to fig. 11, where fig. 11 is a schematic flow diagram of still another failure processing method provided by the embodiment of the present disclosure. The method is performed by a network side device. As shown in fig. 11, the method may include, but is not limited to, the steps of:

Step S1101: and sending configuration information of at least one cell or cell group to the terminal equipment.

In the embodiment of the present disclosure, step S1101 may be implemented by any one of the embodiments of the present disclosure, which is not limited thereto, and is not described in detail.

Step S1102: and receiving the indication information sent by the terminal equipment.

In the embodiment of the present disclosure, step S1102 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S1103: after receiving the indication information sent by the terminal equipment, reconfiguring configuration information of the first cell or cell group, or determining whether the current terminal equipment has the configuration information of the first cell or cell group; alternatively, it is determined whether the current terminal device uses stored configuration information of the first cell or cell group.

The first cell or cell group is one or more cells or cells in which the terminal equipment fails to read the corresponding configuration information.

As an example, the network side device reconfigures the configuration information of the first cell or the cell group after receiving the indication information sent by the terminal device.

As another example, after receiving the indication information sent by the terminal device, the network side device determines whether the current terminal device has configuration information of the first cell or the cell group.

As yet another example, after receiving the indication information sent by the terminal device, the network side device determines whether the terminal device uses the configuration information of the first cell or the cell group that is already stored in the terminal device.

By implementing the embodiment of the disclosure, the network side device can receive the indication information sent by the terminal device, so that the network side device can acquire whether the terminal device fails to read the configuration information or fails to reconfigure, and the network side device can perform subsequent operations based on the indication information. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability. In one implementation manner of the embodiment of the disclosure, after receiving the indication information sent by the terminal device, the network side device reconfigures configuration information of the first cell or the cell group and sends the reconfigured configuration information to the terminal device. As an example, please refer to fig. 12, fig. 12 is a flowchart illustrating another failure processing method according to an embodiment of the disclosure. The method is performed by a network side device. As shown in fig. 12, the method may include, but is not limited to, the steps of:

Step S1201: and sending configuration information of at least one cell or cell group to the terminal equipment.

In the embodiment of the present disclosure, step S1201 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S1202: and receiving the indication information sent by the terminal equipment.

In the embodiment of the present disclosure, step S1202 may be implemented in any one of the embodiments of the present disclosure, which is not limited to this and is not repeated herein.

Step S1203: and reconfiguring configuration information of the first cell or the cell group.

In the embodiment of the present disclosure, step S1203 may be implemented in any of the embodiments of the present disclosure, which is not limited thereto, and is not repeated herein.

Step S1204: and sending configuration information to the terminal equipment.

For example, the network side device sends the reconfigured configuration information to the terminal device, and the configuration information is reconfigured by the network side device according to the received indication information sent by the terminal device.

By implementing the embodiment of the disclosure, after receiving the indication information sent by the terminal equipment, the network side equipment reconfigures the configuration information of the first cell or the cell group and sends the reconfigured configuration information to the terminal equipment, so that the terminal equipment performs subsequent operations based on the configuration information. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

In the embodiments provided in the present disclosure, the method provided in the embodiments of the present disclosure is described from the angles of the terminal device and the network side device, respectively. As can be seen from the above embodiments of the present disclosure, by using the failure processing method provided by the present disclosure, after determining that the configuration information of the cell group included in the mobility configuration information sent by the network side fails, the terminal device may execute any one or more of a plurality of processing procedures corresponding to the reading failure based on its own situation, so as to avoid the influence of the reading failure on the subsequent mobility operation. The processing procedure corresponding to the reading failure comprises the following steps: continuing to use the original stored configuration information; and sending indication information for indicating the reading failure to the network side equipment for sending the mobility configuration information so as to request the network side equipment to reconfigure the mobility configuration information.

It should be noted that the mobility configuration information includes configuration information for selective activation of a cell or a cell group, where the configuration information of the cell or the cell group is configuration information of a corresponding "cell or cell group to be activated" (for example, may be an RRC reconfiguration message).

Specifically, the terminal device receives mobility configuration information sent by the network side device, and reads configuration information of a cell group included in the configuration information. If the terminal device successfully reads the configuration information of the cell group included in the configuration information, the terminal device updates the mobility configuration information stored in itself based on the read configuration information (e.g., stores the read new mobility configuration information in the Var variable). If the terminal equipment fails to read the configuration information, executing at least one of the following processing procedures corresponding to the reading failure:

1) Corresponding configuration information of a cell or a cell group configured by the network side equipment is ignored;

the cells or cell groups are one or more cells or cell groups which fail to read the corresponding configuration information by the terminal equipment.

In an alternative implementation, the terminal device may ignore the corresponding mobility configuration of the cell group for which reading the cell group configuration information failed.

In an alternative implementation, the terminal device may delete the mobility configuration corresponding to the cell group in which the terminal device stored cell group configuration information was not read.

As an example, taking the mobility configuration information described above as an example including the trigger condition, the ID, and the cell group configuration information, if the terminal device fails to read the cell or cell group configuration information, the corresponding trigger condition, the ID, and the like stored in the terminal device need to be deleted.

As an example, taking the above mobility configuration information including the trigger condition, the ID, and the cell group configuration information as an example, if the terminal device fails to read the cell or cell group configuration information, only the cell or cell group configuration information may be deleted.

Alternatively, other terminal devices cannot trigger access to this cell or group of cells according to their mobility configuration.

2) Continuing to use the original configuration information;

in an alternative implementation, the terminal device may continue to use the stored mobility configuration provided that the terminal device has already stored mobility configuration information corresponding to the cell or group of cells for which the reading failed.

In an alternative implementation manner, if the terminal device originally stores mobility configuration information corresponding to a cell or a cell group that fails to be read, the terminal device may continue to use the configuration information in the mobility configuration information corresponding to the cell or the cell group, and not update the configuration information of the cell or the cell group in the mobility configuration information corresponding to the cell or the cell group, but update other configuration information therein.

It should be noted that, if the terminal device originally stores the mobility configuration information corresponding to the cell group, the mobility configuration information issued by the network includes the mobility configuration corresponding to the cell, and then the mobility configuration of the cell group is updated, and the terminal device fails to read the configuration information, that is, the update fails.

3) Transmitting indication information to network side equipment;

for example, the terminal device sends indication information to the network side device sending mobility configuration information, informing the network side device of failure to read the configuration information of a certain cell group or failure to reconfigure. The indication information includes an identifier of a cell or a cell group which fails to be read, an identifier of corresponding mobility configuration information, an identifier of configuration information of a corresponding cell or cell group, and a reason (or type) of the failure to be read.

In an alternative implementation, the indication information may be a separate 1bit indication.

In an alternative implementation, when it is assumed that the terminal device ignores configuration information of the first cell or cell group configured by the network side device, the indication information may also instruct the terminal device to ignore mobility configuration of the cell group.

Optionally, the indication information may carry a reason that the terminal device ignores the configuration information of the first cell or the cell group configured by the network side device, where the reason may be a reading failure or a reconfiguration failure.

Optionally, the indication information may further include an identification of a cell or a cell group that fails to be read, an identification of corresponding mobility configuration information, and an identification of configuration information of a corresponding cell or cell group.

In an alternative implementation, the indication information may also indicate whether the terminal device continues to use the original configuration.

Optionally, the indication information may also indicate that the terminal device uses an original mobility configuration, or an original configuration of a cell or a cell group.

In an alternative implementation manner, the indication information may further include a cell group identifier, an identifier of corresponding mobility configuration information, and an identifier of configuration information of a corresponding cell group.

Optionally, the indication information may also be sent by the terminal device, where the reason may be a reading failure or a reconfiguration failure.

4) Entering an IDLE IDLE state;

5) Starting a reconstruction process;

6) The secondary cell group SCG is released.

In this way, after determining that the reading of the configuration information fails, the terminal device may execute a processing procedure corresponding to the reading failure. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

For the network side equipment, if the terminal equipment fails to read the configuration information and executes the operation of sending the indication information to the network side equipment, the network side equipment can reconfigure the configuration of the corresponding cell or cell group which fails to be read by the terminal equipment after receiving the indication information, and send new configuration information obtained by reconfiguration to the terminal equipment; or, the network side device may determine whether the terminal device currently has a mobility configuration corresponding to the cell group; alternatively, the network side device may determine whether the terminal device currently uses the original configuration information of the cell or cell group. Therefore, after receiving the indication information sent by the terminal equipment, the network side equipment can reconfigure the configuration information of the cell or the cell group and send the reconfigured configuration information to the terminal equipment, so that the terminal equipment performs subsequent operations based on the configuration information. In this way, the occurrence of selective activation failure of the cell or the cell group can be avoided, thereby improving the communication reliability.

It should be noted that, in the embodiment of the present disclosure, the configuration information of the cell or the cell group is the configuration information described above.
