[0078] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0079] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network-side equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0080] First, let's introduce and explain several terms used in this application:

[0081] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0082] The network-side equipment involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network-side equipment can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network-side equipment can also coordinate the attribute management of the air interface.

[0083] For example, the network-side equipment involved in the embodiments of this application can be a base transceiver station (BTS) in Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a network-side device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), an evolved network-side device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network-side equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may also be geographically separated.

[0084] Network-side equipment and terminal equipment can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0085] Secondly, the existing related technologies involved in this application will be introduced and explained:

[0086] (a) Deactivate the secondary cell group (SCG)

[0087] In multi-connectivity scenarios, there is one Master Cell Group (MCG) and one or more Secondary Cell Groups (SCGs). The Master Node (MN) side's cell group is the Master Cell Group, consisting of one Master Cell (PCell) and zero to multiple Secondary Cells (SCells). The Secondary Node (SN) side's cell group is the Secondary Cell Group, also consisting of one SCG Master Cell (PSCell) and zero to multiple Secondary Cells. Current technologies only support dual-connectivity scenarios. In connected mode, the UE is configured with dual connectivity, and both the MN and SN can simultaneously interact with the UE.

[0088] To save energy and quickly activate the SCG for data transmission, the UE can set the SCG side to deactivate the SCG when the data transmission volume is small. In the deactivation state, the UE does not monitor the Physical Downlink Control Channel (PDCCH) on the SCG side, nor does it transmit the Physical Uplink Shared Channel (PUSCH).

[0089] (II) Activating / Deactivating SCG

[0090] The MN / SN / UE can request SCG activation; the network-triggered SCG activation command is sent from the MN to the UE. The MN / SN can also request SCG deactivation; the network-triggered SCG deactivation command is sent from the MN to the UE. During SCG activation / deactivation, Radio Resource Control (RRC) signaling is used for interaction between the UE / MN and the MN / SN.

[0091] When a UE receives an SCG activation command, if the command instructs the UE to perform a Random Access Channel (RACH) procedure to activate the SCG, the UE will execute the RACH procedure to activate the SCG. If the command does not instruct the UE to use a RACH procedure, the UE can perform RACH-less SCG activation (without a RACH procedure, directly activating the SCG) under certain conditions, such as when TAT is running and no BF / RLF is detected. That is, the UE can directly listen to the PDCCH or directly send uplink (UL) data (if UL resources are available). If these conditions are not met, the UE still needs to use common RACH resources to perform a RACH procedure to activate the SCG. When the UE needs to use a RACH procedure to activate the SCG, if the received activation command includes dedicated RACH resources, the UE will use those resources for SCG activation. If the command does not include dedicated RACH resources, the UE will use common RACH resources for SCG activation.

[0092] (III) Statistical Records of Random Access Related Information

[0093] In the current mechanism, when a UE successfully completes a random access procedure, it records relevant information in its random access (RA) report, including the purpose of random access and random access resource information. When a UE fails to complete a random access procedure, it records relevant information in its connection establishment failure (CEF) or radio link failure (RLF) report, primarily including random access resource information. When the network requests the UE to report the recorded RA or CEF / RLF report, the UE reports the recorded RA or CEF / RLF report to the network side for RACH analysis and optimization.

[0094] The SCG activation process introduced in Multi-Radio Dual Connectivity (MDRC) technology may affect the UE's statistical recording of random access-related information.

[0095] For example, when a UE activates an SCG through the RACH procedure, if random access is successful and the SCG is successfully activated, the UE will need to record the relevant information of this successful random access in the RA report. However, there is no corresponding SCG activation option in the RA purpose of the RA report.

[0096] Furthermore, if the activation command sent by the network does not include a RACH indication, the network may assume the UE can perform SCG activation without a RACH procedure. However, if the UE fails to perform SCG activation without a RACH procedure under certain conditions, and then successfully activates the SCG by triggering a contention-based random access procedure, the UE will only record the last successful random access, omitting the intermediate SCG activation process without a RACH procedure. Thus, when the network receives the RA report, it only knows that the random access was for SCG activation and was successfully performed through the RACH procedure, unaware that the UE also experienced a failed SCG activation without a RACH procedure. This prevents the network from optimizing the SCG activation process.

[0097] In addition, when a UE fails to activate SCG, under the current mechanism, the UE does not report complete SCG activation process information. As a result, the network side does not have sufficient auxiliary information to optimize the failure, the optimization effect is not obvious, and it cannot effectively reduce the probability of SCG activation failure.

[0098] In view of this, embodiments of this application propose a method for recording information related to the SCG activation process. This method can record random access-related information and other auxiliary information during the SCG activation process completely and accurately to help the network side optimize RACH resource configuration and decide on the SCG activation method, thereby reducing SCG activation latency and lowering the probability of SCG activation failure.

[0099] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0100] This application provides an information processing method, such as... Figure 1 As shown, the method includes:

[0101] S101. Receive the secondary cell group (SCG) activation command from the network side;

[0102] S102. Activate the SCG according to the SCG activation command, record the relevant information of the SCG activation process, and report it to the network side.

[0103] In this embodiment, when the UE activates the SCG according to the SCG activation command from the network side, it records relevant information during the SCG activation process and reports it to the network side, thereby assisting the network side in optimizing the SCG activation process, reducing SCG activation latency, and lowering the probability of SCG activation failure.

[0104] In one possible implementation, in S102, activating the SCG according to the SCG activation command may include:

[0105] Based on the information in the SCG activation command indicating whether to activate the SCG through the Random Access Channel (RACH) procedure, the method for activating the SCG is determined, and the SCG is activated according to the determined method.

[0106] Specifically, there are two ways to determine the activation method of SCG:

[0107] In the first scenario: if the network side indicates that the RACH procedure is not used to activate the SCG, the UE determines the method of activating the SCG based on the status information of its own advance timer (TAT), the results of radio link monitoring (RLM) and / or beam failure detection (BFD).

[0108] 1. If the TAT is detected to be in operation and no beam failure (BF) or radio link failure (RLF) is detected, the SCG activation method is determined to be that the UE performs SCG activation without a RACH procedure; that is, the SCG activation process is performed directly without performing a RACH procedure.

[0109] 2. If any of the following preset conditions are met, the method for activating SCG is determined to be that the UE uses public RACH resources to activate SCG during the RACH process;

[0110] The preset conditions include:

[0111] The UE's SCG activation without RACH procedure failed.

[0112] The TAT has been detected as having timed out or stopped;

[0113] BF detected;

[0114] RLF detected.

[0115] The second scenario: If the network side indicates that the SCG should be activated using the RACH procedure, the activation method of the SCG is determined based on whether the SCG activation command carries the dedicated RACH resources configured by the network side.

[0116] 1. If dedicated RACH resources configured on the network side are carried, the method for activating SCG is determined to be activating SCG using dedicated RACH resources during the RACH process;

[0117] 2. If the dedicated RACH resources configured on the network side are not carried, or if the UE fails to activate the SCG using dedicated RACH resources, the activation method for the SCG is determined to be that the UE uses public RACH resources to activate the SCG using public RACH resources.

[0118] It should be noted that, in the above embodiments, the network-side indication methods are as follows:

[0119] The first method is to include an indication message in the SCG activation command, which instructs the UE to activate the SCG through the Random Access Channel (RACH) procedure; or, instructs the UE not to activate the SCG through the Random Access Channel (RACH) procedure.

[0120] The second approach is as follows: If the network side instructs the UE to activate the SCG during the Random Access Channel (RACH) procedure, then the SCG activation command includes an instruction to activate the SCG during the RACH procedure; if the network side instructs the UE not to activate the SCG during the RACH procedure, then the instruction is not included in the SCG activation command.

[0121] In another possible implementation, S102 may specifically include:

[0122] Activate the SCG according to the SCG activation command; if the SCG activation is successful, record the relevant information of the successful SCG activation process in the Random Access RA report.

[0123] Specifically, in this embodiment, the relevant information for the successful SCG activation process includes at least one of the following:

[0124] The purpose of this random access procedure is to activate the SCG;

[0125] The random access channel (RACH) resource information used in this random access procedure, namely: the dedicated and / or public RACH resource information used by the UE;

[0126] Information used to indicate whether the current SCG activation process uses a no-RACH SCG activation process; for example: indicating that the current SCG activation process uses a no-RACH SCG activation process, or indicating that the current SCG activation process does not use a no-RACH SCG activation process.

[0127] Reasons for not using the SCG activation process without RACH; for example: UL out-of-synchronization, BF, RLF, etc.

[0128] Information used to indicate the activation result of the SCG without RACH; for example: indicating that the SCG activation without RACH was successful, or indicating that the SCG activation without RACH failed;

[0129] Record TA-related information in advance at regular intervals; for example, the TAT value configured by the network side for the UE, the TAT running value when the SCG activation command is received, and the indication information of TAT running when the SCG activation command is received, etc.

[0130] Radio Resource Management (RRM) measurement-related information, namely: the latest RRM measurement results of the UE when it receives the SCG activation command;

[0131] Beam-related information; for example, it may include information such as beam index and beam measurement results.

[0132] In the SCG activation command, the transmission configuration configured on the network side indicates the TCI status information. If a BF occurs during SCG activation, the network side can send the configured TCI status information to the UE, and the UE can record this network-configured TCI status information.

[0133] Information used to indicate whether the network side indicates whether to use the RACH process to activate the SCG in the SCG activation command; that is: record the first indication information, which is used to indicate "whether the network side indicates whether to use the RACH process to activate the SCG in the SCG activation command";

[0134] This is used to indicate whether the SCG activation command carries information about the dedicated RACH resource configured on the network side for activating the SCG; that is, to record the second indication information, which is used to indicate whether the SCG activation command carries the dedicated RACH resource configured on the network side for activating the SCG.

[0135] UE's location and speed information when receiving the SCG activation command;

[0136] The time interval from receiving the SCG activation command to the successful activation of the SCG;

[0137] The time interval from when the timer advance timer (TAT) is detected to expire or stop to when the UE receives the SCG activation command; that is, when the SCG activation command is received, if the TAT has expired or stopped (that is, the TAT has expired or stopped when the SCG is deactivated), then the time interval from when the UE detects the TAT timeout or stop to when the UE receives the SCG activation command needs to be recorded.

[0138] The time interval from the detection of beam failure (BF) or radio link failure (RLF) to the UE receiving the SCG activation command is recorded. That is, when the SCG activation command is received, if BF or RLF has already occurred (meaning that BF or RLF has already occurred when the TAT is in the SCG deactivation state), the time interval from the UE detecting BF or RLF to the UE receiving the SCG activation command needs to be recorded.

[0139] In another possible implementation, the method may also include:

[0140] S103. In response to a request from the network side, the RA report is sent to the network side, wherein the RA report is used by the network side to optimize the SCG activation configuration and / or optimize RACH resources.

[0141] For example, if the SCG activation process involves a UE failing to activate SCG without a RACH procedure but successfully activating it via a RACH procedure, the network side, based on the RA report, analyzes the data and finds that the purpose of this random access procedure was to activate the SCG. Since the SCG activation command did not instruct the UE to use the RACH procedure, there was a previous SCG activation failure without a RACH procedure before the RACH procedure. The network side then investigates the reasons for the failure and other conditions (such as RRM measurement results and beamforming results). Therefore, in this case, the analysis concludes that the SCG activation command should directly instruct the UE to perform SCG activation based on the RACH procedure to reduce SCG activation latency.

[0142] It should be noted that the UE can report the RA report to the MN on the network side for optimization, or the MN can send the information in the received RA report, in whole or in part, to the SN via the X2 / Xn interface for optimization, or the MN and SN can jointly perform optimization; alternatively, the UE can directly send the RA report to the SN on the network side for optimization.

[0143] In another possible implementation, S102 may specifically include:

[0144] Activate the SCG according to the SCG activation command; if the SCG activation fails, record the relevant information of the SCG activation failure process in the Radio Link Failure (RLF) report or the SCG failure information message.

[0145] Specifically, in this embodiment, the relevant information of the SCG activation failure process includes at least one of the following:

[0146] The failure type is SCG activation failure;

[0147] The random access channel (RACH) resource information used in this random access procedure, namely: the dedicated and / or public RACH resource information used by the UE;

[0148] Information used to indicate whether the current SCG activation process uses a no-RACH SCG activation process; for example: indicating that the current SCG activation process uses a no-RACH SCG activation process, or indicating that the current SCG activation process does not use a no-RACH SCG activation process.

[0149] Reasons for not using the SCG activation process without RACH; for example: UL out-of-synchronization, BF, RLF, etc.

[0150] Information used to indicate the activation result of the SCG without RACH; for example: indicating that the SCG activation without RACH was successful, or indicating that the SCG activation without RACH failed;

[0151] Record TA-related information in advance at regular intervals; for example, the TAT value configured by the network side for the UE, the TAT running value when the SCG activation command is received, and the indication information of TAT running when the SCG activation command is received, etc.

[0152] Radio Resource Management (RRM) measurement-related information, namely: the latest RRM measurement results of the UE when it receives the SCG activation command;

[0153] Beam-related information; for example, it may include information such as beam index and beam measurement results.

[0154] In the SCG activation command, the transmission configuration configured on the network side indicates the TCI status information. If a BF occurs during SCG activation, the network side can send the configured TCI status information to the UE, and the UE can record this network-configured TCI status information.

[0155] Information used to indicate whether the network side indicates whether to use the RACH process to activate the SCG in the SCG activation command; that is: record the first indication information, which is used to indicate "whether the network side indicates whether to use the RACH process to activate the SCG in the SCG activation command";

[0156] This is used to indicate whether the SCG activation command carries information about the dedicated RACH resource configured on the network side for activating the SCG; that is, to record the second indication information, which is used to indicate whether the SCG activation command carries the dedicated RACH resource configured on the network side for activating the SCG.

[0157] UE's location and speed information when receiving the SCG activation command;

[0158] The time interval from receiving the SCG activation command to the successful activation of the SCG;

[0159] The time interval from when the timer advance timer (TAT) is detected to expire or stop to when the UE receives the SCG activation command; that is, when the SCG activation command is received, if the TAT has expired or stopped (that is, the TAT has expired or stopped when the SCG is deactivated), then the time interval from when the UE detects the TAT timeout or stop to when the UE receives the SCG activation command needs to be recorded.

[0160] The time interval from the detection of beam failure (BF) or radio link failure (RLF) to the UE receiving the SCG activation command is recorded. That is, when the SCG activation command is received, if BF or RLF has already occurred (meaning that BF or RLF has already occurred when the TAT is in the SCG deactivation state), the time interval from the UE detecting BF or RLF to the UE receiving the SCG activation command needs to be recorded.

[0161] In another possible implementation, the method may also include:

[0162] S104, Send an SCG failure message to the network side; or...

[0163] S105. In response to the request from the network side, report the RLF report to the network side;

[0164] The RLF report or SCG failure message is used by the network side to analyze the reasons for the SCG activation failure and to optimize the SCG activation configuration and / or RACH resources.

[0165] It should be noted that the UE can send an RLF report or SCG failure information message to the MN. The MN can then send part or all of the content of the received RLF report or SCG failure information message to the SN via the X2 / Xn interface. The MN and / or the SN analyze that the failure is due to SCG activation failure and determine the specific cause of the failure. Alternatively, the UE can send the RLF report directly to the SN. The SN analyzes that the failure is due to SCG activation failure and determines the specific cause of the failure. For example, if the RACH resource configuration is unreasonable, corresponding RACH resource optimization will be performed to reduce the probability of SCG activation failure.

[0166] This application provides an information processing method, such as... Figure 2 As shown, this method, applied to the network side, includes:

[0167] S201. Send a secondary cell group (SCG) activation command to the UE, wherein the SCG activation command is used by the UE to activate the SCG.

[0168] S202. Receive relevant information about the SCG activation process reported by the UE, wherein the relevant information about the SCG activation process is information recorded by the UE during the SCG activation process.

[0169] In one possible implementation, the network side includes a primary node (MN) and a secondary node (SN). If the MN receives information related to the SCG activation process reported by the UE, the method further includes:

[0170] MN performs optimization processing based on the relevant information of the SCG activation process;

[0171] The MN sends all or part of the relevant information of the SCG activation process to the SN so that the SN can perform optimization processing, or the SN and MN can perform optimization processing together.

[0172] If the SN receives information related to the SCG activation process reported by the UE, the method further includes:

[0173] SN performs optimization processing based on the relevant information from the SCG activation process.

[0174] In other words, after the MN on the network side receives the relevant information about the SCG activation process reported by the UE, it can optimize based on the information, or send the received information completely or partially to the SN through the X2 / Xn interface for optimization, or the MN and SN can jointly optimize; or the SN on the network side receives the relevant information about the SCG activation process reported by the UE and can optimize based on the information.

[0175] In another possible implementation, the optimization process includes:

[0176] Based on the information related to the successful SCG activation process recorded in the Random Access RA report, optimize the SCG activation configuration and / or RACH resources.

[0177] Based on the relevant information about the SCG activation failure process recorded in the Radio Link Failure (RLF) report or SCG failure message, analyze the cause of this SCG activation failure, and optimize the SCG activation configuration and / or RACH resources.

[0178] Specifically, in this embodiment, the SCG activation process involves a UE failing to activate SCG without a RACH procedure but successfully activating it via a RACH procedure. The network side analyzes the RA report submitted by the UE and finds that the purpose of this random access procedure was to activate the SCG. Since the SCG activation command did not instruct the UE to use the RACH procedure to activate the SCG, there was a previous failure to activate SCG without a RACH procedure before the RACH procedure. The reasons for the failure and other conditions (such as RRM measurement results and beam measurement results) were investigated. Therefore, it was determined that in this case, the SCG activation command should directly instruct the UE to perform SCG activation based on the RACH procedure to reduce SCG activation latency.

[0179] If the MN receives an RLF report or SCG failure message from the UE, it can send part or all of the content of the received RLF report or SCG failure message to the SN. The MN and / or SN will then analyze that the failure is due to SCG activation failure and determine the specific cause of the failure. Alternatively, if the SN receives an RLF report from the UE, the SN will analyze that the failure is due to SCG activation failure and determine the specific cause of the failure. For example, if the RACH resource configuration is unreasonable, corresponding RACH resource optimization will be performed to reduce the probability of SCG activation failure.

[0180] In other words, the information processing method provided in this application embodiment sends an SCG activation command to the UE for UE to activate SCG, and receives relevant information recorded by the UE during the SCG activation process reported by the UE, thereby optimizing the SCG activation process based on the relevant information of the SCG activation process, reducing SCG activation latency, and lowering the probability of SCG activation failure.

[0181] The following describes, with reference to Examples 1 to 3, the application of an information processing method provided in this application in different SCG activation scenarios.

[0182] Example 1: SCG activation scenario where "UE fails to activate SCG without RACH procedure, but successfully activates SCG through RACH procedure".

[0183] like Figure 3 The methods shown include:

[0184] S301. The network side sends an SCG activation command to the UE. This SCG activation command does not instruct the UE to use the RACH procedure to activate the SCG.

[0185] S302. After receiving the SCG activation command, if the UE detects that the TAT is still running and no BF or RLF is detected, the UE performs SCG activation without RACH, and the SCG activation fails.

[0186] S303, The UE uses the public RACH resource to activate the SCG using the RACH procedure, and the SCG activation is successful;

[0187] S304. The UE records relevant information about the SCG activation process in the RA report, including one or more of the following:

[0188] 1) The purpose of this random access procedure, i.e., the RA purpose, is to activate the SCG;

[0189] 2) The RACH resource information used in this random access procedure, i.e., the public RACH resource information used by the UE;

[0190] 3) An indication message 1, indicating that the SCG activation process uses a no-RACH SCG activation procedure;

[0191] 4) An indication message 2, used to indicate that the SCG activation failed without a RACH process;

[0192] 5) TA-related information can record the TAT value configured for the UE by the network side, the TAT running value when the SCG activation command is received, and the indication information of TAT running when the SCG activation command is received.

[0193] 6) RRM measurement related information, i.e., the latest RRM measurement results information of the UE when it receives the SCG activation command;

[0194] 7) Beam-related information, which may include beam index, beam measurement results, and other related information;

[0195] 8) In the SCG activation command, the TCI status information configured on the network side; if a BF occurs during SCG activation, the network side can send the configured TCI status information to the UE, and the UE can record this TCI status information configured on the network side.

[0196] 9) An indication message 3, used to indicate that in the SCG activation command, the network side instructs the UE not to use the RACH procedure to activate the SCG;

[0197] 10) An indication message 4, used to indicate that no dedicated RACH resource is configured on the network side to activate SCG in the SCG activation command;

[0198] 11) UE location and speed information upon receiving the SCG activation command;

[0199] 12) The time interval from receiving the SCG activation command to the successful activation of the SCG.

[0200] S305, The network side requests the UE to report the RA report.

[0201] S306a, UE reports RA report to MN.

[0202] S306c and MN will send the received RA report to SN.

[0203] It should be noted that the UE reports the RA report to the MN, and the MN can analyze the RA report based on it. Alternatively, the MN can send all or part of the information received in the RA report to the SN.

[0204] S306b, UE reports RA report to SN.

[0205] S307. After receiving the RA report from the MN, the SN analyzes it, or the MN and SN analyze it jointly; or the SN analyzes it after receiving the RA report from the UE; or the MN analyzes it after receiving the RA report from the UE. This analysis reveals that the purpose of this random access procedure is to activate the SCG. Since the SCG activation command does not instruct the UE to use the RACH procedure to activate the SCG, there was a failed SCG activation without a RACH procedure before the RACH procedure. The reasons for the failed SCG activation without a RACH procedure and other conditions (such as RRM measurement results, beam measurement results, etc.) were investigated. Therefore, it is determined that in this case, the UE should be directly instructed to perform RACH-based SCG activation in the SCG activation command to reduce SCG activation latency.

[0206] Example 2: The following examples can be included for the scenario where "UE successfully activates SCG directly using RACH procedure".

[0207] Example 1:

[0208] Step 1-a: The SCG activation command sent by the network side instructs the UE to activate the SCG using the RACH procedure, and the SCG activation command carries dedicated RACH resources.

[0209] Step 2: After receiving the SCG activation command, the UE uses dedicated RACH resources to perform the RACH procedure and successfully activate the SCG.

[0210] Step 2-a: After receiving the SCG activation command, the UE uses dedicated RACH resources to perform the RACH process, but the SCG activation fails. The UE then uses public RACH resources to perform the RACH process and successfully activates the SCG.

[0211] Step 3-a: The UE records one or more of the following information in the RA report:

[0212] 1) The purpose of this random access process is to activate the SCG;

[0213] 2) RACH resource information used in this random access procedure, i.e., the dedicated RACH resources and / or public RACH resource information used by the UE;

[0214] 3) An indication message 5, indicating that the SCG activation process did not use the RACH-free SCG activation process;

[0215] 4) Reasons for not using the RACH-free activation process, such as: TAT has timed out or stopped, BF has been detected, or RLF has been detected;

[0216] 5) TA-related information can record the TAT value configured for the UE by the network side, the TAT running value when the SCG activation command is received, and the indication information of TAT running when the SCG activation command is received.

[0217] 6) RRM measurement related information, i.e., the latest RRM measurement results information of the UE when it receives the SCG activation command;

[0218] 7) Beam-related information, which may include beam index, beam measurement results, and other related information;

[0219] 8) In the SCG activation command, the transmission configuration configured on the network side indicates the TCI status information; if a BF occurs during SCG activation, the network side can send the configured TCI status information to the UE, and the UE can record this network-side configured TCI status information.

[0220] 9) An instruction message 6, used to indicate whether the network side indicates whether to use the RACH procedure to activate the SCG in the SCG activation command;

[0221] 10) An indication message 7, used to indicate whether the network side has a dedicated RACH resource configured to activate SCG in the SCG activation command;

[0222] 11) UE location and speed information upon receiving the SCG activation command;

[0223] 12) The time interval from receiving the SCG activation command to the successful activation of the SCG;

[0224] 13) The time interval from when the timing advance timer TAT is detected to have timed out or stopped until the UE receives the SCG activation command;

[0225] 14) The time interval from the detection of beam failure (BF) or radio link failure (RLF) to the UE receiving the SCG activation command.

[0226] Step 4-a: The network side requests the UE to report the RA report.

[0227] Step 5-a1: The UE reports the RA report to the MN, and the MN sends the received RA report to the SN.

[0228] It should be noted that the UE reports the RA report to the MN, and the MN can analyze the RA report based on it. Alternatively, the MN can send all or part of the information received in the RA report to the SN.

[0229] Step 5-a2: The UE reports the RA report to the SN.

[0230] Step 6-a1: After receiving the RA report sent by the MN, the SN analyzes it, or the MN and SN analyze it together, and find that the purpose of this random access process is to activate the SCG, and analyze the SCG activation process.

[0231] Step 6-a2: After receiving the RA report from the UE, the SN analyzes it and finds that the purpose of this random access procedure is to activate the SCG, and analyzes the SCG activation process.

[0232] Based on the analysis in step 6-a1 or step 6-a2 above, it was found that the UE failed to perform random access using the dedicated RACH resources configured in the SCG activation command, but successfully activated the SCG using public RACH resources. The network side determined that the failure was caused by the unreasonable configuration of the dedicated RACH resources. Therefore, the configuration of the dedicated RACH resources was optimized to reduce the SCG activation latency.

[0233] Example 2:

[0234] Step 1-b: The SCG activation command sent by the network side instructs the UE to activate the SCG using the RACH procedure, and the SCG activation command does not carry dedicated RACH resources;

[0235] Step 2-b: After receiving the SCG activation command, the UE uses public RACH resources to perform the RACH process and successfully activates the SCG;

[0236] The other steps in this scheme can be referred to steps 3-a to 5-a2 in Example 1 above. For the sake of brevity, they will not be repeated here.

[0237] Example 3:

[0238] Step 1-c: The SCG activation command sent by the network side does not instruct the UE to use the RACH procedure to activate the SCG;

[0239] Step 2-c: After receiving the SCG activation command, the UE finds that the TAT has timed out or stopped, or detects a BF, or detects an RLF. At this time, the UE uses public RACH resources to perform the RACH process and successfully activates the SCG.

[0240] Steps 3-c to 6-c2 can be referred to as steps 3-a to 6-a2 in Example 1 above. For the sake of brevity, they will not be repeated here.

[0241] Based on the analysis in step 6-c1 or step 6-c2, it was found that the purpose of this random access procedure was to activate the SCG. The SCG activation command instructed the UE not to activate the SCG using the RACH method. The UE successfully activated the SCG using the public RACH resource through the RACH procedure. The reasons why the UE used the RACH method to activate the SCG were also understood (such as the TAT timeout, the detection of BF, or the detection of RLF). Therefore, it was analyzed that in this case, the UE should be directly instructed to perform RACH-based SCG activation in the SCG activation command to reduce the SCG activation latency.

[0242] Example 3: For the scenario of "UE activation SCG failure".

[0243] When the UE receives the SCG activation command, it performs either a no-RACH or RACH activation procedure based on whether a RACH procedure is required, as indicated in the received activation command, and the UE's own TAT, RLM, and BFD detection status. However, the SCG activation ultimately fails. The UE can record one or more of the following information in the RLF report or SCG failure message:

[0244] 1) Failure type, i.e., SCG activation failed;

[0245] 2) RACH resource information used in this random access procedure, i.e., the dedicated RACH resources and / or public RACH resource information used by the UE;

[0246] 3) An indication message 8 indicates whether a no-RACH SCG activation process was performed during this SCG activation process;

[0247] 4) One indication message 2 indicates that the SCG activation failed without a RACH process;

[0248] 5) Reasons for not activating SCG without RACH process, such as: TAT has timed out or stopped, BF was detected, or RLF was detected;

[0249] 6) TA-related information can record the TAT value configured for the UE by the network side, the TAT running value when the SCG activation command is received, and the indication information of TAT running when the SCG activation command is received.

[0250] 7) Beam-related information: If SCG is activated and BF is detected, this includes information related to failed beams, such as failed beam indexes and beam measurement results.

[0251] 8) RRM measurement related information, i.e., the latest RRM measurement results information of the UE when it receives the SCG activation command;

[0252] 9) In the SCG activation command, the transmission configuration configured on the network side indicates the TCI status information; if a BF occurs during SCG activation, the network side can send the configured TCI status information to the UE, and the UE can record this network-side configured TCI status information.

[0253] 10) An instruction message 6, used to indicate whether the network side indicates whether to use the RACH procedure to activate the SCG in the SCG activation command;

[0254] 11) An instruction message 7, used to indicate whether the network side configures dedicated RACH resources to activate SCG in the SCG activation command;

[0255] 12) UE location and speed information upon receiving the SCG activation command;

[0256] 13) The time interval from receiving the SCG activation command to the SCG activation failure;

[0257] 14) The time interval from when the timing advance timer (TAT) is detected to have timed out or stopped until the UE receives the SCG activation command;

[0258] 15) The time interval from the detection of beam failure (BF) or radio link failure (RLF) to the UE receiving the SCG activation command.

[0259] The UE sends an RLF report or SCG failure message to the MN. The MN can send part or all of the content of the received RLF report or SCG failure message to the SN. The MN and / or SN analyze that the failure is due to SCG activation failure and analyze the specific reasons for the failure. Alternatively, the UE can send the RLF report directly to the SN. The SN analyzes that the failure is due to SCG activation failure and analyzes the specific reasons for the failure, such as unreasonable RACH resource configuration, and performs corresponding RACH resource optimization to reduce the probability of SCG activation failure.

[0274] The RLF report or SCG failure message is used by the network side to analyze the reasons for the SCG activation failure and to optimize the SCG activation configuration and / or RACH resources.

[0284] This information is used to indicate whether the RACH procedure is used to activate the SCG in the SCG activation command;

[0285] This is used to indicate whether the SCG activation command carries information about the dedicated RACH resource configured on the network side for activating the SCG.

[0286] UE's location and speed information when receiving the SCG activation command;

[0287] The time interval from receiving the SCG activation command to the successful activation of the SCG;

[0296] The sending module 501 is used to send a secondary cell group (SCG) activation command to the UE, wherein the SCG activation command is used by the UE to activate the SCG.
