Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information processing method, user equipment, and storage medium. Background Technology

[0002] During the process of accessing the network for communication, the User Equipment (UE) needs to record and report the mobility history information of the SCG (Secondary Cell Group) to the network side as required for communication.

[0003] The MRDC (Multi-Radio Dual Connectivity) project introduced an SCG deactivation state. When there is no data transmission on the SCG side, the network side can deactivate the SCG. When the network side wants to activate the SCG, it can send an SCG activation command to reactivate the SCG.

[0004] Currently, when a UE receives a synchronization reconfiguration command from the SCG side and the SCG state is indicated as deactivated, the UE will not immediately execute the RACH (Random Access Channel) procedure to access the target SCG's PSCell. Instead, it will wait until the SCG is activated before performing the RACH procedure to access the target SCG's PSCell. This will affect the UE's recording and reporting of current SCG-side mobility history information. Summary of the Invention

[0101] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0102] It should be noted that the terms "first" and "second" in the embodiments of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. The term "and / or" in the embodiments of this application describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0103] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0104] Figure 1This is an application scenario diagram of an information processing method provided in an embodiment of this application. This embodiment is applicable to multi-connection scenarios, which include at least one UE and one network-side device. The network-side device can be an MN or SN, and the UE can be a mobile phone, tablet, computer with wireless transceiver capabilities, VR (virtual reality) terminal, AR (augmented reality) terminal, wireless terminal in industrial control, etc.

[0105] In a multi-connectivity scenario, there can be one primary cell group and one or more secondary cell groups. The cell group on the MN side is the primary cell group, consisting of one primary cell and zero or more secondary cells. The cell group on the SN side is the secondary cell group, consisting of one SCG primary cell and zero or more secondary cells.

[0106] The MN, SN, or UE can request SCG activation; the SCG activation command triggered by the network side can be sent from the MN to the UE. The MN or SN can also request SCG deactivation; the SCG deactivation command triggered by the network side can be sent from the MN to the UE. During SCG activation or deactivation, RRC (Radio Resource Control) signaling can be used for interaction between the UE and network-side equipment, or between network-side equipment.

[0107] The inventors discovered that when a UE receives a PSCell (Primary SCGCell, the primary cell in a secondary cell group) change command, PSCell addition command, Handover command, or RRC (Radio Resource Control) Resume command indicating that the SCG activation state is SCG deactivated, the UE does not immediately execute the RACH procedure to access the target SCG's PSCell. Instead, it waits until the SCG is activated before executing the RACH procedure to access the target SCG's PSCell. This will affect the recording and reporting of the current SCG's UE mobility history information; that is, the UE is unsure whether it should continue recording the mobility history information of the source SCG's PSCell or start recording the mobility history information of the target SCG's PSCell.

[0108] If the UE continues to record the mobility history information of the source SCG's PSCell, after reporting it to the network side, the network side may assume that from the time the UE receives the PSCell change command, PSCell addition command, Handover command, or RRC Resume command until the SCG is activated, the source SCG's PSCell has been in a connected state and can transmit data normally. However, in reality, the network side has already notified the UE to access the target SCG's PSCell. At this time, the uplink or downlink of the source SCG's PSCell may have already lost synchronization. It's just that the SCG side does not have any transmission services at the moment, so it does not need to immediately access the target SCG side.

[0109] If the UE starts recording the mobility history information of the target SCG's PSCell, after reporting it to the network side, the network side may assume that from the time the UE receives the PSCell change command, PSCell addition command, Handover command, or RRCresum command until the SCG is activated, the target SCG's PSCell has been in a connected state and can transmit data normally. However, in reality, the UE has not performed the RACH procedure to access the target SCG's PSCell at this time.

[0110] Based on this, embodiments of this application provide an information processing method, a user equipment, and a storage medium. After receiving a first command, the user equipment can record the UE's movement history information on the SCG side. The first command includes an SCG synchronization reconfiguration command and carries an SCG deactivation indication. Through this method, even when the UE receives an SCG synchronization reconfiguration command indicating that the SCG state is deactivated, it can still record movement history information on the SCG side.

[0111] Figure 2 This application provides an interactive flowchart of an information processing method according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0112] In step S201, MN or SN sends the first command to UE.

[0113] When there is no data transmission on the SCG side and the PSCell where the UE is located needs to be switched, the MN or SN can send a first command to the UE. This first command includes an SCG synchronization reconfiguration command and carries an SCG deactivation indication. The SCG synchronization reconfiguration command can also be written as a PSCell synchronization reconfiguration command. The first command can be a PSCell change command, a PSCelladdition command, a Handover command, or an RRC Resume command, etc.

[0114] In step S202, the UE receives the first command.

[0115] Step S203: The UE records the UE's movement history information on the SCG side.

[0116] In one optional implementation, the mobility history information on the SCG side may include at least one of the following: first mobility history information of the source SCG's PSCell, where the source SCG's PSCell is the PSCell where the UE is currently located; second mobility history information of the target SCG's PSCell, where the target SCG's PSCell is the PSCell indicated by the first command; and third mobility history information for the time period from receiving the first command to receiving the second command; wherein the second command carries an SCG activation indication.

[0117] In step S204, the UE can obtain an indication by sending mobile history information to the MN or SN;

[0118] Step S205: MN or SN sends a mobile history information reporting request to UE;

[0119] In step S206, the UE sends the SCG side's mobility history information to the MN or SN.

[0120] In one optional implementation, after recording the mobile history information on the SCG side, the UE can send a mobile history information availability indication to the MN or SN; and receive a mobile history information reporting request sent by the MN or SN; the UE can report the mobile history information on the SCG side to the MN or SN according to the mobile history information reporting request.

[0121] The following will describe in detail an information processing method provided in this application through six embodiments.

[0122] Example 1

[0123] The UE is currently connected to the PSCell of the source SCG, and the SCG is active. If the UE receives a first command including an SCG synchronization reconfiguration command and indicating that the SCG's active state is changed to an inactive state, the UE may continue to record at least one of the following: the identifier of the source SCG's PSCell, the time interval from when the UE connected to the source SCG's PSCell to when the UE activated the SCG, or the time interval from when the UE connected to the source SCG's PSCell to when the UE successfully connected to the target SCG's PSCell during the RACH procedure, and the first mobility history information described below. The first command may be any one of a PSCell change command, a Handover command, or an RRC Resume command.

[0124] The PSCell ID of the source SCG is an optional identifier of the PSCell of the source SCG. In the embodiments of this application, the ID can be PCI (Physical Cell Identifier) ​​and frequency point, or it can be CGI (Cell Global Identifier).

[0125] When the UE receives any one of the following commands: PSCell change command, Handover command, or RRC Resume command (which carries information about the PSCell of the target SCG), and the command indicates that the SCG is inactive, the UE can continue to record the identifier of the source SCG's PSCell and at least one of the following first mobility history information:

[0126] 1. Indication information used to indicate that the UE has received the first command; that is, when the UE receives the PSCell change command, Handover command or RRC Resume command, and indicates that the SCG activation state is SCG deactivation state, the UE will record a reception indication information to indicate that the UE has received the first command. No matter how many first commands the UE receives before activating the SCG or successfully accessing the PSCell of the target SCG during the RACH process, the UE will only record one indication information.

[0127] 2. Number of times the first command is received; that is, the number of times the UE receives the first command before successfully accessing the PSCell of the target SCG during SCG activation or RACH process.

[0128] 3. The identifier of the target SCG's PSCell contained in each first command; that is, the UE will record the identifier of the target SCG's PSCell contained in the first command received before activating the SCG or successfully accessing the target SCG's PSCell during the RACH procedure, such as the ID of the target SCG's PSCell; and can be recorded in the form of a list.

[0129] 4. Each first command; that is, the UE will record the first command received before activating the SCG or successfully accessing the target SCG's PSCell by performing the RACH procedure. The first command can be a PSCell change command, a PSCelladdition command, a Handover command, or an RRC Resume command, and can be recorded in the form of a list.

[0130] 5. The time interval from when the UE accesses the PSCell of the source SCG to when it receives each first command; that is, the duration from when the UE accesses the PSCell of the source SCG to when the UE receives each first command can be recorded, and can be recorded in the form of a list.

[0131] 6. The time interval from when the UE accesses the PSCell of the source SCG to when it receives the first command; that is, the duration from when the UE accesses the PSCell of the source SCG to when the UE receives the first command can be recorded.

[0132] 7. The time interval between two consecutive receipts of the first command;

[0133] 8. The time interval from receiving the first command to receiving the second command; that is, the UE can record the duration from receiving the first command to receiving a normal SCG activation command, or the duration from receiving the first command to receiving a PSCell change command, Handover command, or RRC Resume command, and the duration in which the command indicates that the SCG state is SCG active.

[0134] 9. RRM (Radio Resource Management) measurement results information;

[0135] 10. Beam measurement results information.

[0136] In one embodiment, the UE may also record the duration from the last receipt of the first command to the receipt of a normal SCG activation command, or the duration from the last receipt of the first command to the receipt of a PSCell change command, a Handover command, or an RRC Resume command, wherein the command indicates that the SCG activation state is SCG active.

[0137] After recording the mobile history information on the SCG side, the UE can report to the MN or SN an indication that the UE mobile history information on the SCG side is available. After receiving the indication, the MN or SN can request the UE to report the mobile history information on the SCG side through a UE Information Request message. The UE Information Request is an optional mobile history information reporting request. After receiving the UE Information Request message, the UE can report the recorded mobile history information on the SCG side to the MN or SN through a UE Information Response message.

[0138] After receiving the mobile history information from the SCG side reported by the UE, the MN or SN can analyze whether the UE received the first command in a source SCG's PSCell, namely the PSCell change command, Handover command, or RRC Resume command, and whether the command indicates that the SCG activation state is SCG deactivation state. If the MN or SN analyzes that the UE received the first command, it can analyze that when the UE received the first command, the UE may actually have lost synchronization with the source SCG's PSCell's UL (Uplink) and DL (Downlink), thereby performing further analysis and optimization.

[0139] Example 2

[0140] The UE is not currently configured with an SCG. If the UE receives a first command that includes an SCG synchronization reconfiguration command and indicates that the SCG activation state is SCG deactivation state, the first command can be any one of the following commands: PSCell addition command, Handover command, or RRCresume command. Since the UE has not previously configured an SCG, it will not be recorded. The UE will only start recording the SCG-side mobility history information after activating the SCG or successfully accessing the PSCell of the target SCG by performing the RACH procedure.

[0141] Example 3

[0142] The UE is currently connected to the PSCell of the source SCG, and the SCG is active. When the UE receives a first command including an SCG synchronization reconfiguration command, the UE can record at least one of the following second mobility history information: That is, when the UE receives any one of the following commands—a PSCellchange command, a Handover command, or an RRC Resume command—and indicates that the SCG activation state is changed to an SCG deactivation state, the UE can record at least one of the following second mobility history information:

[0143] 1. The identifier of the PSCell of the target SCG included in each first command, and the time interval between two consecutive first commands received; For example, the UE can record the ID of the PSCell of the target SCG included in each first command received, and the duration of the UE in each target SCG's PSCell, that is, the duration from the UE receiving each first command to receiving the next PSCell change command, Handover command or RRC Resume command, and the duration of the command indicating that the SCG is inactive or deactivated, or the duration of the command indicating that the SCG is active.

[0144] 2. First indication information; This first indication information is used to indicate that the UE did not perform the random access channel RACH procedure to access the PSCell of the target SCG;

[0145] 3. Second indication information; This second indication information is used to indicate whether the UE activates the PSCell of the target SCG or whether the UE performs the RACH procedure to access the PSCell of the target SCG before receiving the next SCG synchronization reconfiguration command.

[0146] 4. The time interval between receiving each first command and receiving the second command; that is, the time from when the UE receives each first command to when the UE successfully accesses the PSCell by executing the RACH procedure;

[0147] 5. RRM measurement results information;

[0148] 6. Beam measurement results information.

[0149] After recording the mobile history information on the SCG side, the UE can report to the MN or SN an indication that the UE mobile history information on the SCG side is available. After receiving the indication, the MN or SN can request the UE to report the mobile history information on the SCG side through a UE Information Request message. After receiving the UE Information Request message, the UE can report the recorded mobile history information on the SCG side to the MN or SN through a UE Information Response message.

[0150] After the MN or SN receives the mobile history information from the SCG side reported by the UE, it can analyze whether the UE did not perform the RACH procedure to access the PSCell of the target SCG during the process of recording the PSCell of a target SCG. That is, whether the UE has never synchronized with the UL of the PSCell of the target SCG, or when the UE randomly accessed the PSCell of the target SCG, that is, when the UE synchronized with the UL of the PSCell. This allows for further analysis and optimization.

[0151] Example 4

[0152] The UE is not currently configured with an SCG. Upon receiving a first command including an SCG synchronization reconfiguration command, the UE can record at least one of the following second mobility history information. The first command can be any one of a PSCell addition command, a Handover command, or an RRC Resume command; that is, when the UE receives any one of these commands, and the command indicates that the SCG activation state is changed to the SCG deactivation state, the UE can record at least one of the following second mobility history information:

[0153] 1. The identifier of the PSCell of the target SCG included in each first command, and the time interval between two consecutive first commands received; For example, the UE can record the ID of the PSCell of the target SCG included in each first command received, and the duration of the UE in each target SCG's PSCell, that is, the duration from the UE receiving each first command to receiving the next PSCell change command, Handover command or RRC Resume command, and the duration of the command indicating that the SCG is inactive or deactivated, or the duration of the command indicating that the SCG is active.

[0154] 2. First indication information; This first indication information is used to indicate that the UE did not perform the random access channel RACH procedure to access the PSCell of the target SCG;

[0155] 3. Second indication information; This second indication information is used to indicate whether the UE activates the PSCell of the target SCG or whether the UE performs the RACH procedure to access the PSCell of the target SCG before receiving the next SCG synchronization reconfiguration command.

[0156] 4. The time interval between receiving each first command and receiving the second command; that is, the time from when the UE receives each first command to when the UE successfully accesses the PSCell by executing the RACH procedure;

[0157] 5. RRM measurement results information;

[0158] 6. Beam measurement results information.

[0159] After recording the mobile history information on the SCG side, the UE can report to the MN or SN an indication that the UE mobile history information on the SCG side is available. After receiving the indication, the MN or SN can request the UE to report the mobile history information on the SCG side through a UE Information Request message. After receiving the UE Information Request message, the UE can report the recorded mobile history information on the SCG side to the MN or SN through a UE Information Response message.

[0160] After the MN or SN receives the mobile history information from the SCG side reported by the UE, it can analyze whether the UE did not perform the RACH procedure to access the PSCell of the target SCG during the process of accessing the PSCell of the target SCG, that is, whether the UE has never synchronized with the UL of the PSCell, or when the UE randomly accessed the PSCell, that is, when the UE synchronized with the UL of the PSCell. This allows for further analysis and optimization.

[0161] Example 5

[0162] The UE is currently connected to the PSCell of the source SCG, and the SCG is active. When the UE receives a first command, including an SCG synchronization reconfiguration command, it stops recording the identifier and duration of the source SCG's PSCell and begins separately recording the UE's mobility history information from receiving the first command to receiving the second command. Specifically, when the UE receives any one of the following commands: PSCell change, Handover, or RRC Resume, and this command indicates that the SCG's active state has changed to an inactive state, the UE can stop recording the identifier and duration of the source SCG's PSCell and begin separately recording third mobility history information during this process. This process refers to the period from the UE first receiving the first command to receiving the second command, and the third mobility history information is at least one of the following:

[0163] 1. The PSCell identifier of the source SCG and the PSCell identifier of the target SCG contained in each first command; the PSCell identifier of the source SCG and the PSCell identifier of the target SCG contained in each received second command; for example, the UE may record the PSCell ID of the source SCG and the PSCell ID of the target SCG contained in each first command in a new entry, or may record the last received PSCell change command, Handover command or RRC Resume command in a new entry, and the PSCell ID of the source SCG and the PSCell ID of the command indicating that the SCG is in an active state, and may record them in the form of a list;

[0164] 2. The identifier of the source SCG PSCell contained in the first command and the identifier of the target SCG PSCell contained in the second command; For example, the UE may record in a new entry the ID of the source SCG PSCell contained in the first command received and the ID of the target SCG PSCell contained in the second command received.

[0165] 3. The time interval between two consecutive receipts of the first command; for example, the UE can record the duration from the receipt of the first command to the receipt of the next first command in a new entry;

[0166] 4. The time interval between each received first command and the receipt of the second command; For example, the UE can record the duration between each receipt of the first command and the receipt of the second command in a new entry, including the time interval between the UE receiving the last first command and the UE receiving a normal SCG activation command, and the time interval between the UE receiving the last first command and the UE receiving a PSCell change command, Handover command, or RRC Resume command, and the command indicating that the SCG is active.

[0167] 5. Number of times the first command was received; that is, the number of times the UE counts and records the number of times the first command was received before successfully accessing the PSCell of the target SCG during SCG activation or RACH process.

[0168] 6. Each first command received; that is, the UE will record each first command received before activating the SCG or successfully accessing the target SCG's PSCell by performing the RACH procedure. The first command can be a PSCell change command, a PSCell addition command, a Handover command, or an RRC Resume command, and can be recorded in the form of a list.

[0169] 7. RRM measurement results information;

[0170] 8. Beam measurement results information.

[0171] After recording the mobile history information on the SCG side, the UE can report an indication that the UE mobile history information on the SCG side is available to the primary node MN or the secondary node SN. After receiving the indication, the MN or SN can request the UE to report the mobile history information on the SCG side through the UE Information Request message. The UE Information Request is an optional mobile history information reporting request. After receiving the UE Information Request message, the UE can report the recorded mobile history information on the SCG side to the MN or SN through the UE Information Response message.

[0172] After receiving the mobile history information from the SCG side reported by the UE, the MN or SN can analyze whether the UE has actually lost synchronization with the uplink or downlink of the target SCG while staying in a PSCell, whether the UE has not performed the RACH procedure to access the target SCG's PSCell, i.e., the UL of the UE and the target SCG's PSCell are out of synchronization, and how long this state has lasted; or what commands the UE received before activating the SCG or performing the RACH procedure to access the target SCG's PSCell, and the source SCG's PSCell ID and the target SCG's PSCell ID in these commands, and thus perform further analysis and optimization.

[0173] Example 6

[0174] The UE is not currently configured with an SCG. After the UE receives a first command including an SCG synchronization reconfiguration command, the UE can begin separately recording mobility history information from the time it receives the first command to the time it receives the second command. The first command can be any one of a PSCell addition command, a Handover command, or an RRC Resume command. That is, when the UE receives any one of these commands and indicates that the SCG activation state is SCG deactivation, the UE can begin separately recording third mobility history information during this process. This process refers to the time from the first time the UE receives the first command to the time it receives the second command. The third mobility history information is at least one of the following:

[0175] 1. The PSCell identifier of the source SCG and the PSCell identifier of the target SCG contained in each first command; the PSCell identifier of the source SCG and the PSCell identifier of the target SCG contained in each received second command; for example, the UE may record the PSCell ID of the source SCG and the PSCell ID of the target SCG contained in each first command in a new entry, or may record the last received PSCell change command, Handover command or RRC Resume command in a new entry, and the PSCell ID of the source SCG and the PSCell ID of the command indicating that the SCG is in an active state, and may record them in the form of a list;

[0176] 2. The identifier of the source SCG's PSCell contained in the first command and the identifier of the target SCG's PSCell contained in the received second command; For example, the UE may record the PSCell ID of the source SCG contained in the first command and the PSCell ID of the target SCG contained in the received second command in a new entry.

[0177] 3. The time interval between two consecutive receipts of the first command; for example, the UE can record the duration from the receipt of the first command to the receipt of the next first command in a new entry;

[0178] 4. The time interval between each received first command and the receipt of the second command; For example, the UE can record the duration between each receipt of the first command and the receipt of the second command in a new entry, including the time interval between the UE receiving the last first command and the UE receiving a normal SCG activation command, and the time interval between the UE receiving the last first command and the UE receiving a PSCell change command, Handover command, or RRC Resume command, and the command indicating that the SCG is active.

[0179] 5. Number of times the first command was received; that is, the number of times the UE counts and records the number of times the first command was received before successfully accessing the PSCell of the target SCG during SCG activation or RACH process.

[0180] 6. Each first command received; that is, the UE will record each first command received before activating the SCG or successfully accessing the target SCG's PSCell by performing the RACH procedure. The first command can be a PSCell change command, a PSCell addition command, a Handover command, or an RRC Resume command, and can be recorded in the form of a list.

[0181] 7. RRM measurement results information;

[0182] 8. Beam measurement results information.

[0183] After recording the mobile history information on the SCG side, the UE can report an indication that the UE mobile history information on the SCG side is available to the primary node MN or the secondary node SN. After receiving the indication, the MN or SN can request the UE to report the mobile history information on the SCG side through the UE Information Request message. The UE Information Request is an optional mobile history information reporting request. After receiving the UE Information Request message, the UE can report the recorded mobile history information on the SCG side to the MN or SN through the UE Information Response message.

[0184] After receiving the mobile history information from the SCG side reported by the UE, the MN or SN can analyze whether the UE has actually lost synchronization with the uplink or downlink of the target SCG while staying in a PSCell, whether the UE has not performed the RACH procedure to access the target SCG's PSCell, i.e., the UL of the UE and the target SCG's PSCell are out of synchronization, and how long this state has lasted; or what commands the UE received before activating the SCG or performing the RACH procedure to access the target SCG's PSCell, and the source SCG's PSCell ID and the target SCG's PSCell ID in these commands, and thus perform further analysis and optimization.
