Description

Technical Field

[0001] (Cross-reference to Related Applications) This application claims the priority of Chinese Patent Application No. 202210306878.2, filed in China on March 25, 2022, the entire content of which is incorporated herein by reference. This disclosure relates to the technical field of communications, and in particular, to an information transmission method, an information reception method, a device, and a storage medium.

Background Art

[0002] In a dual-connection scenario, if a user equipment (UE) detects that a radio link failure (RLF) has occurred in a master cell group (MCG), and the UE is configured with a mechanism for fast MCG connection recovery, the UE suspends the transmission of all radio bearers of the MCG and transfers MCG error information, such as measurement results of MCG and / or SCG cells measured by the UE, to a master node (MN) via a secondary cell group (SCG). Within a certain preset time length (T316), the UE may receive feedback messages such as radio resource control (RRC) reconfiguration, handover, RRC release, etc. transferred from the MN via the SCG and perform subsequent operations. On the other hand, if none of the above messages transmitted from the MN are received by the UE even after exceeding the preset time length, the UE starts a re-establishment procedure. According to the fast MCG connection recovery mechanism, it can help the UE to recover the connection with the MCG as soon as possible, thus avoiding the UE starting re-establishment and entering the idle state, which may affect the UE's service experience.

[0003] A drawback of the related technology is that, due to parameter configuration issues, the MCG connection recovery mechanism is unable to recover the connection between the UE and the MCG and / or SCG as quickly as possible.

[0060] The inventor noticed the following during the invention process. If the UE detects an MCG failure during a Conditional Primary / Secondary Cell (PSCell) Change (CPC), the UE will directly perform the re-establishment procedure. If the Secondary Node (SN), SCG, or PSCell is in an inactive state (in the following description, "SCG inactive" refers to these three cases), the network can be configured to allow the UE to perform fast MCG connection recovery in the event of an MCG failure. Compared to a normal dual connection, if the SCG is inactive, the UE must first activate the SCG in order to report MCG error information via the SN. Different parameters such as T310, N311, and T316 may be used to detect potential MCG failures and SCG inactive states more quickly. After a terminal receives an MN reconfiguration, handover, or RRC release command, an MCG Failure may be detected immediately after the reconfiguration becomes effective (e.g., a longer T310, a shorter N311, etc.) (e.g., within a certain preset time), or a new MCG Failure may occur immediately after a cell is changed in accordance with a handover command, or an RRC connection with the target cell may not be established, or the UE may detect that the MCG signal quality has recovered to a relatively good level after receiving an RRC release command, or the UE may not have received any information from the network side when T316 expires (this may be because T316 was set too short, or the MN configuration was too slow, or the signal quality of the SN, SCG, or PSCell was poor and transmission was unsuccessful), and the UE initiates a re-establishment procedure, resulting in a temporary loss of the RRC connection between the UE and the network side, which may affect data transmission and the UE's service experience. If an MCG Failure occurred while the SCG was in an inactive state, one possible cause is that the UE took too long to activate the SCG, resulting in the UE not yet receiving any network-side feedback information when T316 expired. If the UE can report relevant information at the time of the MCG failure, such as the configuration of T310, N311, and T316, information that the SCG is in an inactive state, the time taken to activate the SCG, information that the UE has received RRC reconstruction information, and information such as the handover target cell and measurement results, it can help the network analyze whether the above-mentioned configured parameters are appropriate and perform the appropriate optimizations.

[0061] Based on this, in the technical embodiments of the present disclosure, a mechanism is proposed in which the UE reports relevant information regarding an MCG failure, which helps the network side configure appropriate parameters, assists the UE in restoring the connection to the MCG and / or SCG as quickly as possible, and improves the user experience.

[0062] Specific embodiments of this disclosure will be described below with reference to the drawings.

[0063] In the explanation, we will first describe the implementation on the UE side and the base station side, and then, in order to better understand the implementation of the embodiments described in the embodiments of this disclosure, we will also give examples of implementations in which the two are linked. This method of explanation does not mean that the two must be implemented in conjunction or independently. In fact, when the UE and base station are implemented separately, the problems on the UE side and the base station side are solved respectively, while when the two are used in combination, better technical effects can be obtained.

[0064] Figure 1 is a schematic diagram of the implementation flow of the information transmission method on the UE side, as shown in the figure, Step 101 may include the UE reporting primary information, which is relevant to Fast Master Cell Group Link Recovery.

[0065] Figure 2 is a schematic diagram of the implementation flow of the information reception method on the base station side, as shown in the figure, Step 201: The base station receives first information, which is first information reported by the UE and is relevant information for the recovery of the high-speed master cell group connection. The base station may also include step 202 of configuring high-speed master cell group connection recovery in accordance with the first information.

[0066] In implementation, the first information is The data is acquired using one or a combination of the following methods: a method recorded by the UE, a method configured for the UE to record via network management, a method configured for the UE to record via TCE, and a method configured for the UE to record via base station.

[0067] Specifically, the above information may be voluntarily recorded by the UE, or it may be configured to be recorded and reported by the UE through network management or trace collection entities (TCEs) or base stations.

[0068] In implementation, the first information is This is reported when the UE is connected, when the UE is transitioning to a connected state, when the UE sends an RRC re-establishment request message, or when the UE sends a radio link failure report.

[0069] Specifically, the UE reports information when it is connected or in the process of transitioning to a connected state, or in RRC re-establishment request messages or wireless link failure reports.

[0070] In implementation, the aforementioned first information is reported upon request from the network side, reported voluntarily by the UE, or reported upon request from the network side after the UE has informed the network side that relevant information exists.

[0071] Specifically, the report states: This information may be requested by the network, voluntarily reported by the UE, or sent by the network after the UE has informed the network that relevant information exists.

[0072] In implementation, the first information is T316 configured by the network side, The parameters used when a master cell group failure (MCG failure) was detected, and the parameters related to radio link failure (RLF) detection, The time difference between the transmission of MCG failure information and the reception of feedback information from the network side, The length of time T316 ran when network feedback was received after the transmission of MCG failure information, The percentage of time T316 was running when network feedback was received after MCG failure information was transmitted, and Information on whether network feedback was received before T316 expired, Information on whether network feedback was received when T316 expired, Feedback information received before T316 expired, Feedback information received when T316 expired, Secondary cell group (SCG) status information, Information on whether the UE is performing a Conditional Primary / Secondary Cell Change (CPC) procedure, Information on whether the UE is performing the Conditional Primary / Secondary Cell Addition (CPA) procedure, Information on whether the UE triggered the CPC, Information on whether the UE triggered the CPA, If a re-establishment or handover occurs, the UE will receive information indicating that a fast master cell group link recovery (fast MCG link recovery) has occurred. If a handover command is received after MCG failure information has been transmitted, the measurement information of the serving cell, adjacent cells, and target cell measured before the start of the handover or during the handover, If a reconfiguration command is received after the transmission of MCG failure information, the reconfigured parameters are as follows: If an RRC release command is received after the transmission of MCG failure information, the measurement results of the master node MN, MCG, or primary cell (PCell) and, If an RRC release command is received after the transmission of MCG failure information, it will be one or more pieces of information, including an instruction that the measurement result exceeded the preset threshold.

[0073] The following describes in detail the reporting of information related to Fast MCG Failure recovery by the UE, as described in A) to K). A) T316 configured by the network side (i.e., the maximum time length of T316 that starts after the transmission of MCG Failure information), which may be expressed as a time length or as a bit representation. For example, T316 can be composed of 10 numbers, where 0000 represents the first configuration. B) RLF detection-related parameters used when an MCG failure was detected, such as one or more of the following (expressed in the same way as T316): T310, N311, or the maximum number of retransmissions for the Radio Link Layer Control (RLC) protocol. C) The time difference between the transmission of MCG failure information and the reception of feedback information from the network side, or the length of time T316 has been running (traveling) when the network side feedback is received, or the percentage of time it has already traveled. D) Information on whether network-side feedback was received before or at the time of T316 expiration. E) Feedback information received before or at the time of T316 expiration, such as RRC reconfiguration, handover, or RRC release. F) This is SCG status information, such as whether it is deactivated or whether it will be deactivated. G)UE CPC or conditions TIFF0007843367000001.tif16166 This file contains information on whether a Conditional PSCell Addition (CPA) procedure is being performed, or whether a CPC or CPA has been triggered. H) If a re-establishment or handover occurs, this is an instruction indicating that the re-establishment or handover was successful or that fast MCG link recovery occurred in related report information such as the RLF report, and it is an instruction to inform the UE that fast MCG link recovery has occurred on the network side. I) If a handover command is received after the transmission of MCG failure information, the measurement information of the serving cell, adjacent cells, and target cell measured before the start of the handover or at the time of the handover is as follows: J) If a reconfiguration command is received after MCG failure information has been transmitted, this information indicates which parameters were reconfigured, for example, new T310, T316, and information indicating that the numerical values ​​of these parameters were selectively reconfigured. K) If an RRC release command is received after MCG failure information has been transmitted, it indicates the measurement result of the MN, MCG, or primary cell (PCell), or an instruction that the measurement result has exceeded the preset threshold.

[0074] The network side (source MCG) can optimize the relevant configuration for high-speed master cell group connection recovery by obtaining data information reported from the terminal and combining it with other information such as RLF reports, UE locations, and measurement results. The implementation of configuring high-speed master cell group connection recovery according to the above first information will be described below as follows (1) to (7).

[0075] 1) If T316 expires, no network-side feedback information has been received, and the UE has re-established the connection, then, based on the T316 configured by the network, information on whether network-side feedback was received before T316 expired, information on whether network-side feedback was received when T316 expired, instructions to the network informing the UE that fast MCG link recovery had occurred in the event of a re-establishment or handover, and the UE's measurement results, if it is determined that the UE could not wait for network-side feedback due to T316 being configured too short, T316 will be configured to be longer. Specifically, if T316 has expired, network-side feedback information has not yet been received, and the UE has re-established, then, according to the aforementioned information A, D, H and the UE's measurement results, the network side will determine whether the UE could not wait for network-side feedback because T316 was configured too short (especially if the MN, MCG, or PCell measurement results are not bad), and if so, the base station will consider configuring T316 to be longer in the subsequent configuration.

[0076] 2) If T316 expires, no network-side feedback information is received, and the UE attempts to re-establish, then, according to the SCG status information, if it is determined that the SCG is inactive at that time, T316 should be configured to be longer, and / or, to prevent the UE from re-establishing too quickly. If T316 has expired, no network-side feedback information has been received, and the UE has re-established, then the parameters corresponding to the detection of the UE's MCG failure should be shortened so that the UE can detect potential RLFs more quickly, according to the information in the RLF detection-related parameters used when the MCG failure was detected. Specifically, if T316 has expired, network-side feedback information has not yet been received, and the UE has re-established, then according to the information in F, if the SCG is in an inactive state at that time, it will take some time for the SCG to recover to activation. Therefore, the network side may consider configuring T316 to be longer to prevent the UE from re-establishing too quickly, and / or, according to the information in B, to configure the parameters corresponding to the detection of the UE's MCG failure, such as T310, N311, or the maximum number of RLC retransmissions, to be shorter so that the UE can detect potential RLFs sooner.

[0077] 3) Based on the time difference between the transmission of MCG failure information and the reception of network-side feedback information, the length of time T316 ran from the transmission of MCG failure information until the reception of network-side feedback, the percentage of time T316 ran when network-side feedback was received after the transmission of MCG failure information, the UE's measurement results, and the length of T316 configured by the network side, if it is determined that the length of time T316 ran when network-side feedback was received is within a predetermined time until expiration, a longer T316 is configured; or if it is determined that the length of time T316 ran when network-side feedback was received exceeds a predetermined time until expiration, a shorter T316 is configured. Specifically, based on information C (the length T316 has run when network feedback is received), the UE's measurement results, and information A (the length of the configured T316), the network can decide, if necessary, to configure a longer T316 (when the length T316 has run is very long and it is nearing expiration when network feedback is received) or a shorter T316 (when the length T316 has run is very short and it is still far from expiration when network feedback is received).

[0078] 4) Based on information regarding whether the UE is performing the CPC procedure, whether the UE is performing the CPA procedure, whether the UE has triggered the CPC, whether the UE has triggered the CPA, and instructions to inform the network that a fast MCG link recovery has occurred if a re-establishment or handover occurs, configure the CPC promptly if an MCG failure occurs during the CPC procedure. Specifically, based on the information in G and H, the network can determine whether an MCG failure occurred in the CPC procedure. If so, it means that the CPC was configured too late, and the CPC needs to be configured earlier.

[0079] 5) If a re-establishment or handover occurs, the UE will be instructed to notify the network that a fast MCG link recovery has occurred, and if a handover command is received after the transmission of MCG failure information, the UE will be determined to be valid based on the measurement information of the serving cell, adjacent cells, and target cell measured before or during the handover. Specifically, based on the information H and I, the network can determine whether the handover configuration information is valid, for example, whether the selection of the handover target frequency point and cell is appropriate.

[0080] 6) If a re-establishment or handover occurs, the UE is notified of an instruction that a fast MCG link recovery has occurred, and the parameters are reconfigured if a reconfiguration command is received after the transmission of MCG failure information. The validity of the newly configured parameters is then determined based on whether an RLF or re-establishment subsequently occurs at the UE. Specifically, according to the information H and J, the network side can determine whether the newly configured parameters are appropriate, depending on whether subsequent situations such as RLF or re-establishment occurred in the UE, for example, if an MCG RLF occurred in the UE after a longer T310 and / or longer T316 was reconfigured.

[0081] 7) If a re-establishment or handover occurs, the UE will be instructed to notify the network that a fast MCG link recovery has occurred, and if a handover command is received after the transmission of MCG failure information, the UE will be determined to determine whether the RRC release command is appropriate based on the measurement information of the serving cell, adjacent cells, and target cell measured before or during the handover.

[0082] Specifically, according to the information H and I, the network side can determine whether the RRC release command is appropriate. For example, if the MN, MCG, or PCell quality measured by the UE is not poor (for example, if the measurement result exceeds the preset threshold), it means that the MCG link has been restored, the MCG should not be released, and T310, N311, or the maximum number of RLC retransmissions is set.
