Description

Message transmission method, terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a message transmission method, a terminal, and a base station.

Background

In a Multi Radio Access Technology Dual-Connectivity (MR-DC) scenario, a terminal may be connected to a Master base station (Master Node, MN) and one or more Secondary base stations (Secondary nodes, SNs) and perform signaling and/or data interaction with these base stations. Both the MN and the SN may be Long Term Evolution (LTE), enhanced Long Term Evolution (LTE), or New Radio interface (New Radio) nodes, and of course, the MN and the SN are not limited to the above type of nodes. In addition, when a terminal is connected with one MN and one SN, it may be referred to as Dual Connection (DC). For example, a terminal may connect to one or more base stations when in a connected state, and the base stations may be in one or more Radio Access Technologies (RATs). For example, when the MN is an LTE node and the SN is NR, it is a 4G radio access network and 5G NR dual connectivity (EN-DC); when MN is NR and SN is (e) LTE, it is 5G NR and 4G radio access network dual connectivity (NE-DC); when both MN and SN are NR, it is 5G NR doubly linked with 5G NR (NR-NR-DC).

In addition, a Secondary Cell Group (SCG) is a Group of serving cells under SN in an MR-DC scenario, and includes one Primary Secondary Cell (PSCell) and possibly one or more Secondary cells (cells). When Radio Link Failure (RLF) occurs in the SCG, the terminal sends an SCG Failure message to the MN to notify the MN of Radio Link Failure occurring at the SN by the SCG Failure message.

However, the SCG failure message can only indicate to the network side that the link of the SCG has failed, so that the network side can establish a new SCG connection for the terminal according to the SCG failure message, but the network side cannot find the reason for the radio link failure according to the SCG failure message.

Detailed Description

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 some, but not all embodiments of the present invention. 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.

Under the MR-DC scenario, SCG related parameters, if not properly configured, may cause SCG failure. And when SCG failure occurs, the terminal sends an SCG failure message to the network under the MN, wherein the message comprises a failure type and a measurement result, but the SCG correction configuration parameter information is not complete. Aiming at the problem, the invention solves the SCG parameter configuration problem in the MR-DC scene by adding the SCG failure message parameter, assists the network side to discover and solve the parameter configuration problem, and improves the network index.

Specifically, as shown in fig. 1, the method is one of the step flow charts of the message transmission method in the embodiment of the present invention, and the method includes the following steps:

step 101: and sending an SCG failure message of the secondary cell group to the base station.

In this step, specifically, the terminal sends an SCG failure message to the base station.

Specifically, the SCG failure message carries at least one of the following parameters: a secondary base station change (SN change) failure determination parameter, a Radio Link Monitoring (RLM) measurement result parameter, a Random Access Channel (RACH) failure configuration determination parameter, and an SN change critical failure determination parameter.

Specifically, the content of the SCG failure message is expanded by carrying at least one of the parameters in the SCG failure message, so that the SCG parameter configuration optimization can be assisted on a network side through the parameters carried by the SCG failure message, the problems existing in MR-DC networking are solved, and network indexes are improved.

The following describes SN change failure determination parameters, RLM measurement result parameters, RACH failure configuration determination parameters, and SN change critical failure determination parameters.

Specifically, an SN change flow may be triggered by an MN or an SN, where the context of a terminal is transferred from a source SN to a target SN, and an SCG configuration is changed from the source SN to the target SN at the terminal side, for example, taking an MN trigger flow as an example, the MN may request the target SN to allocate resources and request the source SN to stop sending data to the terminal, then the MN configures the terminal to execute new configuration and notify the target SN of completion of configuration, and finally, the terminal performs random access at the target SN, and the MN releases the source SN configuration. In addition, in particular, early SN change, late SN change, and SN change to a wrong cell may occur in the SN change of the MR-DC. The terminal accesses a cell with SN for a long time and then SCG failure occurs, and the MN determines that the terminal establishes wireless connection under different SN; the premature SN change is that the terminal has SCG failure in the process of changing from the access source SN to the access to different target SNs or within a short period of time after the terminal has accessed the target SN, and the MN determines that the terminal establishes wireless connection again under the source SN; the SN change to the wrong cell is that the terminal has SCG failure in the process of changing from the source SN to the different target SN or within a short period of time after the terminal has accessed the target SN, and the MN determines that the terminal establishes wireless connection again in a cell which does not belong to the source SN and the target SN.

At this time, for the situations that the too early SN change, the too late SN change, and the SN change arrive at the wrong cell, it may be necessary to adjust the parameter configuration for optimization; of course, both MN and SN may trigger the SN change procedure, i.e. both MN and SN may need to make parameter adjustments. For example, in the scenario that the SN change and the SN change reach a wrong cell too early, the source SN may need to perform parameter adjustment, but after the terminal is connected to the target SN, the source SN does not have a terminal context, and the MN does not know the specific information of the primary and secondary cells under the source SN, so that the terminal is required to add relevant information in the SCG failure message, and at this time, after receiving the SCG failure message, the MN may forward the relevant information to the source SN for use.

At this time, specifically, in the case that the SN change is too early, the SN change is too late, and the SN change arrives at the wrong cell, the embodiment may carry the SN change failure determination parameter in the SCG failure message.

Specifically, the SN change failure determination parameter may include at least one of the following information:

1. failure type information indicating that no SN change has occurred or that an SN change has occurred;

2. identification information of a primary cell and a secondary cell in which Radio Link Failure (RLF) occurs in SCG when SN change does not occur, or identification information of a target cell in which SN change fails when SN change occurs;

3. identification information of a primary cell and a secondary cell connected with a terminal before SN change occurs;

4. the length of time between the SN change occurrence to the SCG occurrence of a radio link failure.

It should be noted that the identification information may be a global cell identifier, or a combination of a frequency point and a physical cell identifier, and is not limited herein.

Note that the unit of the time length may be seconds.

Specifically, the determination of the early SN change, the late SN change, and the SN change to the wrong cell can be performed through the information in the SN change failure determination parameter. For example, when the too-late SN change determination is performed, the failure type information indicates that an SN change does not occur, and the MN needs to select a new SN to establish a wireless connection through measurement and determination, and at this time, the too-late SN change may be counted once in a primary and secondary cell where a wireless link failure occurs; in addition, when premature SN change is carried out, the failure type information indicates that the SN change occurs, meanwhile, the time length from the SN change to the SCG wireless link failure is short, the MN needs to establish wireless connection again under the source SN through measurement and judgment, and at the moment, the premature SN change can be counted once under the primary and secondary cells before the SN change occurs; in addition, the failure type information indicates that SN change occurs, and the time length from the SN change occurrence to the SCG radio link failure occurrence is short, and the MN needs to establish a radio connection under another SN different from the source SN and the target SN by measurement and judgment, and at this time, the SN change may be counted once to a wrong cell under the primary and secondary cells before the SN change occurs.

In this way, the judgment of the early SN change, the late SN change and the SN change to the wrong cell is realized through the SN change failure judgment parameter, and the optimal adjustment of the SN change failure judgment parameter on the parameter configuration of the early SN change, the late SN change and the SN change to the wrong cell can be realized.

Secondly, the network side configures a Radio Link Monitoring configuration (Radio Link Monitoring Config) resource for the terminal for Monitoring the Radio Link, but the Radio Link Monitoring configuration may cause the RLF of the SCG when the resource configuration is not reasonable. Referring to the existing Radio Link Monitoring Config message, a detection Resource (detection Resource) is configured with a beam for checking, and a pupose is configured as an RLF for RLF detection. For example, when the network side configures the synchronization signal and the physical broadcast channel block (SSB for short) such as SSB1, SSB2, and SSB3 at the detection Resource, and the terminal is actually located in the direction of SSB4 and SSB5, even if the terminal has good signals at SSB4 and SSB5, the SCG RLF is triggered and the SCG failure message is reported because the beam monitored by the radio link is SSB1, SSB2, and SSB 3. That is, the above situation is caused by improper parameter configuration, and in order to avoid this situation, the SCG failure message may carry related information and notify the network side to optimize parameter configuration.

Specifically, for the above situation, the present embodiment may carry the RLM measurement result parameter in the SCG failure message.

Specifically, the RLM measurement result parameter includes measurement result information of the SSB and/or measurement result information of a channel state information reference signal (CSI-RS for short).

Of course, the measurement result may be in the form of RSRP, RSRQ, or SINR, which is not specifically limited herein.

In this way, the RLM measurement result parameter carries the measurement result information of the SSB and/or the measurement result information of the CSI-RS, so that parameter configuration optimization for radio link monitoring can be achieved.

Thirdly, when the SCG fails in random Access, the terminal sends an SCG failure message, where the failure type is random Access Problem (random Access protocol), but the network side cannot further determine the reason of the random Access failure according to the existing message. For this, the embodiment may carry the RACH failure configuration determination parameter in the SCG failure message.

Specifically, the RACH failure configuration judgment parameter includes at least one of the following information:

1. corresponding SSB indexes sent by a random access Preamble (RACH Preamble) and Preamble times sent on each SSB index;

2. corresponding SSB frequency information sent by the RACH Preamble and the signal quality of each SSB;

3. indication information of whether the quality of SSB information corresponding to the configured non-contention random access is less than a preset SSB quality threshold value;

4. the number of times of Preamble sent on auxiliary UpLink (SUL) and/or Normal UpLink (NUL);

5. and falling indication information of non-competitive random access to competitive random access.

It should be noted that the Signal quality of the SSB may be Beam Reference Signal Received Power (BRSRP), beam Reference Signal Received Quality (BRSRQ), beam Signal to Interference plus Noise Ratio (BSINR), and the like. Of course, this is not a limitation.

Therefore, the RACH failure configuration judgment parameters can assist the network side to analyze and judge the reason of the random access failure through the RACH failure configuration judgment parameters, and the success rate of the random access can be improved. For example, if the network side configures the non-contention random access SSB unreasonably, the terminal cannot perform random access successfully using the resource, and the terminal will perform non-contention random access to contention fallback, which may increase the risk of random access failure.

Fourthly, in a successful SN change process, the terminal can be configured to perform measurement collection in the processes of an SN change triggering stage, an SN change executing stage and SN change ending so as to analyze whether the terminal has critical failure or not, and in order to improve the robustness of the SN change, when the critical failure occurs, the network needs to be analyzed and optimized, so that potential problems are solved.

For the problem of SN change critical failure, the embodiment may carry an SN change critical failure determination parameter in the SCG failure message.

Specifically, the SN change critical failure determination parameter includes at least one of the following information:

1. RLM measurement information;

2. beam Failure Detection (BFD) indication information;

3. the time length between the SN change triggering and the SN change success;

4. and respectively in the SN change triggering time interval, the SN change execution time interval and the SN change completion time interval, measuring result information of the primary and secondary cells connected with the terminal.

Specifically, the RLM measurement information may include at least one of timer information, RLM-related reference signal measurement result information, and a value of a Radio Link Control (RLC) retransmission counter.

In addition, the timer may be specifically T310, T312, and the like, and is not specifically limited herein. In addition, the RLM related reference signal measurement result may be in the form of RSRP, RSRQ, or SINR.

In addition, specifically, the BFD indication information may include at least one of beam failure indication information, a value of a beam failure indication counter, and a beam failure reference information measurement result. Of course, the beam failure reference information measurement result may also be in the form of RSRP, RSRQ, or SINR, and is not specifically limited herein.

In addition, specifically, the time length from the SN change triggering to the SN change success may be the value of the timer T304 when the change succeeds.

In addition, specifically, in the SN change triggering period, the SN change executing period, and the SN change completing period, the measurement result may also be in the form of RSRP, RSRQ, or SINR in the measurement result information of the primary and secondary cells to which the terminal is connected, which is not specifically limited herein.

Therefore, by the SN change critical failure judgment parameter, when critical switching fails, whether critical radio link failure occurs or not can be checked, whether signal quality has changed greatly in a switching execution stage or not and whether random access has a problem or not can be checked, so that potential problems can be solved in time, and network indexes can be improved.

In this embodiment, an SCG failure message is sent to the base station, and the SCG failure message carries at least one of an SN change failure determination parameter, an RLM measurement result parameter, an RACH failure configuration determination parameter, and an SN change critical failure determination parameter, so that the parameters can assist the network side in performing SCG parameter configuration optimization, thereby solving the problems in the MR-DC network and improving network indexes.

In addition, as shown in fig. 2, it is a second step flow chart of the message transmission method in the embodiment of the present invention, and the method includes the following steps:

step 201: and receiving an SCG failure message of the secondary cell group sent by the terminal.

Specifically, in this step, the base station receives the SCG failure message transmitted by the terminal.

Specifically, the SCG failure message is extended by carrying at least one of the parameters, so that when the base station receives the SCG failure message sent by the terminal, the SCG parameter configuration optimization can be performed through the parameters carried by the SCG failure message, the problems existing in MR-DC networking are solved, and the network index is improved.

In addition, the unit of the time length may be seconds.

It should be noted that, for the specific introduction of the SN change failure determination parameter, reference may be made to a specific introduction description of the SN change failure determination parameter at the terminal side, and details are not described here again.

In this way, the judgment of the early SN change, the late SN change and the SN change to the wrong cell can be realized through the SN change failure judgment parameter, and the optimal adjustment of the SN change failure judgment parameter on the parameter configuration of the early SN change, the late SN change and the SN change to the wrong cell can be realized.

Second, specifically, the RLM measurement result parameter includes measurement result information of the SSB and/or measurement result information of a channel state information reference signal (CSI-RS for short).

It should be noted that, for the specific introduction of the RLM measurement result parameter, reference may be made to the specific introduction description of the RLM measurement result parameter at the terminal side, and details are not described here again.

In this way, the RLM measurement result parameter carries the measurement result information of the SSB and/or the measurement result information of the CSI-RS, so that the base station side can optimize the parameter configuration for monitoring the radio link.

3. indication information of whether the quality of the SSB information corresponding to the configured non-contention random access is less than a preset SSB quality threshold value;

4. the number of times of preambles sent on auxiliary UpLink (SUL) and/or Normal UpLink (NUL);

5. and falling back indication information of non-competitive random access to competitive random access.

It should be noted that, for the specific introduction of the RACH failure configuration determination parameter, reference may be made to the specific introduction description of the RACH failure configuration determination parameter at the terminal side, and details are not described herein again.

Therefore, the reason of the random access failure can be analyzed and judged through the RACH failure configuration judgment parameters, and the success rate of the random access can be improved.

Fourthly, specifically, the SN change critical failure judgment parameter includes at least one of the following information:

1. RLM measurement information;

2. beam Failure Detection (BFD) indication information;

3. the length of time between the SN change trigger and the SN change success;

In addition, specifically, the BFD indication information may include at least one of beam failure indication information, a value of a beam failure indication counter, and a beam failure reference information measurement result.

It should be noted that, for the specific introduction of the SN change critical failure determination parameter, reference may be made to the specific introduction description of the SN change critical failure determination parameter at the terminal side, and details are not described herein again.

Therefore, by the SN change critical failure judgment parameter, when critical switching fails, the base station can check whether critical radio link failure occurs or not, whether signal quality has changed greatly in a switching execution stage or not, whether random access has problems or not and the like, so that potential problems can be solved in time, and network indexes are improved.

In this embodiment, by receiving an SCG failure message sent by a terminal, and the SCG failure message carries at least one of an SN change failure determination parameter, an RLM measurement result parameter, an RACH failure configuration determination parameter, and an SN change critical failure determination parameter, a base station can perform SCG parameter configuration optimization through the above parameters, thereby solving the problems in an MR-DC network and improving network indexes.
