Description

Message processing and sending method and device, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a message processing method, a message sending method, a message processing apparatus, a message sending apparatus, a terminal device, and a network device.

Background

According to the Rel-16 conclusion, when a User Equipment (UE, also called a terminal) configures a PSCell condition change (intra-SN conditional pscl) in a SN that is triggered by a Secondary Node (SN) and does not participate in a primary node (MN), when the UE detects that a target pscl satisfying an execution condition exists, the UE starts to execute access to the target pscl, and simultaneously receives a Radio Resource Control (RRC) reconfiguration message (to be described, the RRC reconfiguration message is generated based on an original certain RRC configuration, that is, delta configuration is performed based on the original certain RRC configuration) from the MN side, the UE will continue to complete a CPC execution process, and after CPC access is completed, the UE executes the RRC reconfiguration message.

However, if the RRC reconfiguration message includes a configuration related to a source secondary node (S-SN), or the RRC reconfiguration message includes a PSCell change command, because the configuration of a target PSCell to which the terminal needs to access is delta configured based on the S-SN configuration, the UE will continue to execute the RRC reconfiguration message based on the configuration information related to the PSCell in the RRC reconfiguration message, so that the UE will apply the configuration related to the S-SN to the target secondary node (T-SN) when the RRC reconfiguration message includes the configuration related to the S-SN, or execute the PSCell change based on the T-SN configuration when the RRC reconfiguration message includes the PSCell change command, which may cause inconsistency between the configurations of the network side and the UE side, or may even cause failure to trigger the reconfiguration.

As shown in fig. 2, an embodiment of the present invention provides a message processing method, including:

step S201, the terminal equipment which has configured the condition auxiliary node change-added CPAC configuration receives the radio resource control RRC reconfiguration message sent by the network equipment;

It should be noted that, the RRC reconfiguration message is generated based on a certain original RRC configuration, that is, delta (delta) configuration is generated based on the certain original RRC configuration, that is, the indication information indicates which reconfiguration message is based on which information when the RRC reconfiguration message is generated.

For example, the configuration to which the RRC reconfiguration message is generated may include one or more of the following:

m11, when the network device does not need to generate the RRC reconfiguration message according to the first reconfiguration message, the configuration to which the RRC reconfiguration message is generated includes: configuration information related to the SN side, such as cell group configuration, bearer configuration, and the like;

m12, when the network device needs to generate the RRC reconfiguration message according to the first reconfiguration message, the configuration applied to generate the RRC reconfiguration message includes: the configuration carried in the first reconfiguration message, and the cell group configuration, the bearer configuration, the measurement configuration and the like of the MN side.

It should be further noted that the first reconfiguration message may be generated and transmitted to the network device through one or more of the following manners:

when a certain cell group at M21 and S-SN sides needs to update the configuration, a first reconfiguration message is generated and transmitted to an MN side;

m22, when MN or S-SN is ready to switch current PSCell, the (target) SN side generates corresponding first reconfiguration message and transmits the first reconfiguration message to the MN side;

m23, aiming at the inter-SN CPC and CPA, when a target SN in the CPAC configuration needs to reconfigure a candidate PSCell, the target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to the MN side;

and M24, aiming at the intra-SN CPC, when the source SN needs to reconfigure a certain candidate PSCell, the target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to the MN side.

In the present invention, the RRC reconfiguration message received in this case is referred to as a current reconfiguration message, that is, the RRC reconfiguration message received in this case includes indication information for indicating a configuration to which the current reconfiguration message is generated.

Step S202, the terminal equipment receives the RRC reconfiguration message in the process of starting to execute CPAC or after finishing executing CPAC, and then the terminal equipment judges and generates the configuration applied by the RRC reconfiguration message based on the indication information and executes message processing after finishing executing CPAC;

it should be noted that, when the terminal device determines that the current reconfiguration message is received during the process of starting to execute the CPAC or after the CPAC is executed, the configuration to which the RRC reconfiguration message is generated is determined, and then, according to the configuration to which the RRC reconfiguration message is generated, subsequent message processing is executed, so that the behavior of the terminal device side is specified, and the situation that the network is not consistent with the understanding of the terminal is avoided.

Optionally, the indication information includes one or more of:

a11, source configuration indication information;

the source configuration indication information is used for indicating that the RRC reconfiguration message is configured based on a reconfiguration message configured before the CPAC is executed by the terminal equipment;

a12, first indication information;

the first indication information is used for indicating that the RRC reconfiguration message is configured based on the reconfiguration message associated with the PSCell determined by the first indication information, that is, the first indication information is used for determining the PSCell and simultaneously indicating that the current reconfiguration message is configured based on the reconfiguration message associated with the PSCell determined by the first indication information.

It should be further noted that, in this case, the first indication information may include one or more of the following items:

a121, cell group identification;

in particular, the cell group identification may be a cell group ID.

A122, physical Cell Identity (PCI) of the PSCell;

and A123, frequency point information.

Optionally, the RRC reconfiguration message further includes: a configuration related to a source Secondary Cell Group (SCG); it should be noted that the source SCG is an SCG that is accessed before CPAC configuration is performed for the terminal device.

Wherein the configuration related to the source SCG includes one or more of:

b11, updating configuration information of the source SCG;

b12, configuration information of a target SCG generated based on the configuration of the source SCG;

the configuration information in this case includes information of a PSCell change command or a configuration update in the CPC.

B13, carrying updated configuration information with the source SCG;

b14, updating configuration information of the cell group of the master cell group MCG;

for example, the configuration information in this case may include signaling in an inter SN CPC scenario.

It should be noted here that, generally, when one or more of the B11-B14 messages are included in the RRC reconfiguration message, the network device needs to carry the indication information in the transmitted RRC reconfiguration message.

It should be further noted that, because the indication information may include two different information, i.e., a11 and a12, when the terminal device determines the configuration information based on the RRC reconfiguration message after performing CPAC, it is also necessary to distinguish between a11 and a12 for determination, and optionally, the terminal device determines, based on the indication information, the configuration to which the RRC reconfiguration message is generated, where the configuration includes one or more of the following:

c11, if the indication information contained in the RRC reconfiguration message is source configuration indication information, the terminal equipment determines that the RRC reconfiguration message is configured based on the reconfiguration message configured before CPAC is executed;

it should be noted that, when the indication information is source configuration indication information, the terminal determines that one or more of the reconfiguration message of the SN side, the bearer configuration information of the MN side, and the cell group configuration information of the MN side in the RRC reconfiguration message are configured based on the reconfiguration message configured before the CPAC is executed.

And C12, if the indication information included in the RRC reconfiguration message is first indication information, the terminal device determines that the RRC reconfiguration message is configured based on the reconfiguration message associated with the PSCell indicated by the first indication information.

Optionally, the terminal device determines that the RRC reconfiguration message is configured based on a reconfiguration message configured before performing CPAC, or the terminal device determines that the RRC reconfiguration message configuration associated with the PSCell indicated by the first indication information is inconsistent with the current CPAC configuration performed by the terminal device, then the terminal device performs one or more of the following:

it should be noted that the first feedback message is used to indicate that the RRC reconfiguration message is invalid or outdated.

d111, identification information of the RRC reconfiguration message;

d112, the terminal equipment executes the identification information of the primary and secondary cells accessed after CPAC;

d113, identification information of CPAC executed by the terminal equipment.

It should be noted that, in this case, the terminal device generally sends the first feedback message to the secondary node, and then sends the first feedback message to the primary node through the secondary node.

D12, executing the configuration related to the main node in the RRC reconfiguration message, and reporting a second feedback message to the network equipment;

it should be noted that the second feedback message is used to indicate that the terminal device performs the configuration information related to the primary node in the RRC reconfiguration message.

Optionally, the second feedback message includes one or more of:

d1251, configuring a radio bearer;

d1252, radio Link Control (RLC) bearer configuration;

d1253, configuring the cell group.

It should be noted that, in this case, the terminal device may directly send the second feedback message to the primary node, or may send the second feedback message to the secondary node first, and then send the second feedback message to the primary node through the secondary node.

D13, sending an RRC reestablishment request message to the network equipment;

that is, in this case, the terminal does not perform the RRC reconfiguration message, but triggers RRC reestablishment, and transmits an RRC reestablishment request message to the primary node or the secondary node.

Specific applications of the present application are exemplified below.

In the first application situation, the indication information configured by the network for the UE is the source configuration indication information, the UE does not execute the RRC reconfiguration message, and reports the first feedback message to the network through the SN side

Under the condition that the network side configures CPAC for the UE and the network side does not receive CPAC execution success completion information fed back by the UE, the method comprises the following operation steps:

step N11, the network side generates an RRC reconfiguration message sent to the terminal and sends the RRC reconfiguration message to the terminal, and the RRC reconfiguration message contains the related configuration indication information;

optionally, the network side may generate the RRC reconfiguration message according to a first reconfiguration message sent by the SN side, for example, in case N11a: when a certain cell group at the S-SN side needs to update the configuration, a first reconfiguration message is generated and transmitted to the MN side; case N11b: when MN or S-SN prepares to switch current PSCell, the (target) SN side generates corresponding first reconfiguration message and transmits the first reconfiguration message to the MN side; case N11c: aiming at inter-SN CPC and CPA, when a target SN in CPAC configuration needs to reconfigure a candidate PSCell, a target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to an MN side; case N11d: aiming at intra-SN CPC, when a source SN needs to reconfigure a certain candidate PSCell, a target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to an MN side.

If the MN side receives the first reconfiguration message of the SN side, the MN side includes the received first reconfiguration message of the SN side in the RRC reconfiguration message generated by the MN side. The RRC reconfiguration message generated by the MN may further include cell group configuration, bearer configuration, measurement configuration, and the like of the MN. The MN carries the source configuration indication information in the RRC reconfiguration message, and then the MN side issues the RRC reconfiguration message to the UE.

Optionally, the network side directly generates an RRC reconfiguration message, and if the MN side does not receive the first reconfiguration message of the SN side, the MN side generates an RRC reconfiguration message, which at least includes configuration information related to the SN side, such as cell group configuration, bearer configuration, and the like. The MN carries the source configuration indication information in the RRC reconfiguration message, and then the MN side issues the RRC reconfiguration message to the UE.

And step N12: if the UE receives an RRC reconfiguration message sent by the network side during starting or after completing performing the CPAC, the UE checks the RRC reconfiguration message after completing performing the CPAC.

Step N13: after detecting the source configuration indication information, the UE determines that the RRC reconfiguration message at the SN side, and/or the bearer configuration information at the MN side, and/or the cell group configuration information at the MN side, which are included in the RRC reconfiguration message, are configured based on the RRC reconfiguration message before CPAC is executed, the UE does not execute the RRC reconfiguration message, and reports a first feedback message indicating that the RRC reconfiguration message at the network side is invalid or outdated to the MN side through the SN, where the first feedback message includes one or more of the following:

identification information of the RRC reconfiguration message;

new PSCell identity information (i.e., identity information of a primary and secondary cell accessed after the UE executes CPAC);

identification information of CPAC performed by the UE.

Step N14: after receiving the first feedback message sent by the UE, the SN side transmits the first feedback message to the MN through an RRC transfer process.

And in the second application situation, the indication information configured for the UE by the network is source configuration indication information, the UE executes the configuration only related to the MN side and reports a second feedback message to the network through the MN side or the SN side

step N21, the network side generates an RRC reconfiguration message sent to the terminal, and sends the RRC reconfiguration message to the terminal, wherein the RRC reconfiguration message comprises the indication information of the associated configuration;

optionally, the network side may generate the RRC reconfiguration message according to the first reconfiguration message sent by the SN side, for example, in case N21a: when a certain cell group at the S-SN side needs to update the configuration, a first reconfiguration message is generated and transmitted to the MN side; case N21b: when MN or S-SN prepares to switch current PSCell, the (target) SN side generates corresponding first reconfiguration message and transmits the first reconfiguration message to the MN side; case N21c: aiming at inter-SN CPC and CPA, when a target SN in CPAC configuration needs to reconfigure a candidate PSCell, a target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to an MN side; case N21d: aiming at intra-SN CPC, when a source SN needs to reconfigure a certain candidate PSCell, a target SN side generates a corresponding first reconfiguration message and transmits the first reconfiguration message to an MN side.

If the MN side receives the first reconfiguration message of the SN side, the MN side includes the received first reconfiguration message of the SN side in the RRC reconfiguration message generated by the MN side. The RRC reconfiguration message generated by the MN side further includes configuration (measurement configuration, etc.) only related to the MN side, and optionally includes configuration information related to the SN side, such as cell group configuration, bearer configuration, etc. The MN carries the source configuration indication information in the RRC reconfiguration message, and then the MN side sends the RRC reconfiguration message to the UE.

Optionally, the network side directly generates an RRC reconfiguration message, and if the MN side does not receive the first reconfiguration message of the SN side, the MN side generates an RRC reconfiguration message, which includes configuration information related to the SN side, such as cell group configuration, bearer configuration, and the like, and configuration (measurement configuration, and the like) related to the MN side. The MN carries the source configuration indication information in the RRC reconfiguration message, and then the MN side issues the RRC reconfiguration message to the UE.

Step N22: if the UE receives the RRC reconfiguration message sent by the network side during the process of starting to execute the CPAC or after the CPAC is executed, the UE checks the RRC reconfiguration message after the CPAC is executed.

Step N23: after detecting the original configuration indication information, the UE determines that the reconfiguration information of the SN side, the bearer configuration information of the MN side and/or the cell group configuration information of the MN side contained in the RRC reconfiguration message are configured based on the RRC reconfiguration message before CPAC execution, then the UE executes the configuration (configuration of a master cell group, measurement configuration and the like) only related to the MN side in the RRC reconfiguration message, and reports a second feedback message to the network;

optionally, the UE may directly report the second feedback message to the MN side to indicate that the UE only performs part of the configuration in the RRC reconfiguration message; optionally, the UE may also report a second feedback message to the SN side to indicate that the UE only performs part of the configuration in the second feedback message.

If the MN side receives the first reconfiguration message of the SN side, the MN side includes the received first reconfiguration message of the SN side in the RRC reconfiguration message generated by the MN side. The RRC reconfiguration message generated by the MN may further include cell group configuration, bearer configuration, measurement configuration, and the like of the MN. The MN carries the source configuration indication information in the RRC reconfiguration message, and then the MN side sends the RRC reconfiguration message to the UE.

Step N32: if the UE receives the RRC reconfiguration message sent by the network side during the process of starting to execute the CPAC or after the CPAC is executed, the UE checks the RRC reconfiguration message after the CPAC is executed.

The MN carries first indication information in the RRC reconfiguration message, where the first indication information may uniquely determine a PSCell, and the PSCell is a PSCell associated with configuration information associated with the SN side and the RRC reconfiguration message on the MN side. Then, the MN side issues the RRC reconfiguration message to the UE.

Step N42: if the UE receives an RRC reconfiguration message sent by the network side during starting or after completing performing the CPAC, the UE checks the RRC reconfiguration message after completing performing the CPAC.

Step N43: when the UE detects the first indication information, the UE may determine that the configuration of the associated RRC reconfiguration message corresponding to the PSCell in the first indication information is inconsistent with the PSCell corresponding to the configuration after the CPAC is executed by the UE, the UE does not execute the RRC reconfiguration message, and reports a first feedback message indicating that the RRC reconfiguration message on the network side is invalid or over to the MN side through the SN, where the first feedback message includes one or more of the following:

The RRC reconfiguration message generated by the MN side further includes configuration (measurement configuration, etc.) only related to the MN side, and optionally includes configuration information related to the SN side, such as cell group configuration, bearer configuration, etc. The MN carries first indication information in the RRC reconfiguration message, where the first indication information may uniquely determine a PSCell, and the PSCell is a PSCell associated with the RRC reconfiguration message on the SN side received by the MN. Then the MN side sends the reconfiguration message to the UE.

Optionally, the network side directly generates an RRC reconfiguration message, and if the MN side does not receive the first reconfiguration message of the SN side, the MN side generates an RRC reconfiguration message, which includes configuration information related to the SN side, such as cell group configuration, bearer configuration, and the like, and configuration (measurement configuration, and the like) related to the MN side.

Step N53: when the UE detects the first indication information, the UE may determine that the configuration of the associated RRC reconfiguration message corresponding to the PSCell in the first indication information is inconsistent with the PSCell corresponding to the configuration after the UE performs CPAC, and then the UE performs the configuration (configuration of the master cell group, measurement configuration, and the like) only related to the MN side in the RRC reconfiguration message, and reports a second feedback message to the network;
