Description

Technical Field

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

[0002] In related technologies, for multi-connectivity scenarios, if the terminal measures multiple target cells of good quality and the terminal supports multi-connectivity, the target node (also called the target base station) can pre-configure multi-connectivity on the target base station for the terminal during the handover process, enabling the terminal to immediately establish multi-connectivity after switching to the target cell. Taking a dual-connectivity handover scenario as an example, such as... Figure 1 As shown, if dual connectivity has been initiated at the source node (also known as the source base station), and the signal quality of the secondary node (SN, or secondary base station) or primary / secondary cell (PScell) or secondary cell group (SCG) measured by the terminal during the handover process is good, but the signal quality of the source master node (MN, or master base station) or master cell (PCell) or master cell group (MCG) is not good enough, requiring a handover of the master node, master cell, or master cell group, then the target master node can add the secondary node, primary / secondary cell, or secondary cell group in advance. This ensures that the secondary node, primary / secondary cell, or secondary cell group remains unchanged during the master node replacement process, allowing the terminal to immediately obtain high-speed dual connectivity service with the secondary node, primary / secondary cell, or secondary cell group unchanged after a successful handover.

[0144] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0145] Before describing the embodiments of this application, the terms used in the embodiments of this application are defined as follows:

[0146] 1. The master node provides control plane connections from the terminal to the core network in a multi-connection scenario;

[0147] 2. Secondary nodes provide services to terminals in multiple connections, excluding the control plane connection to the core network;

[0148] 3. Primary cell group: A group of serving cells associated with the primary node, including the primary cell and one or more optional secondary cells;

[0149] 4. Primary residential area, the primary residential area within a primary residential area group;

[0150] 5. Secondary cell group: A group of serving cells associated with a secondary node, including primary and secondary cells and one or more optional secondary cells.

[0151] 6. Primary and secondary residential areas, with the primary residential area being the secondary residential area group.

[0152] In addition to regular handover, two enhanced handover technologies have been introduced: DAPS handover and Conditional Handover (CHO).

[0153] DAPS handover is a mechanism that allows a terminal to maintain data communication with both the source and target nodes simultaneously during the handover process. Specifically, the terminal receives data from the source node in the downlink (DL) until the source node receives a handover success message from the target node. Conversely, the terminal sends data to the source node in the uplink (UL) until it successfully connects to the target cell, after which it switches its uplink transmission to the target cell. This DAPS handover mechanism prevents a sharp drop in data plane speed due to handover, thus improving the terminal's user experience.

[0154] In DAPS switching scenarios, there are three possible situations:

[0155] 1) When a terminal experiences a radio link failure (RLF) in the source cell, the terminal stops uplink and downlink data transmission with the source cell and releases the connection with the source cell, but retains the source cell's radio resource control (RRC) reconfiguration information.

[0156] 2) If the terminal fails to handover in the target cell, it can fall back to the configuration of the source cell, maintain a connection with the source cell, and report the DAPS handover failure indication information through the source cell. Here, since the connection between the terminal and the source base station is unreliable at this time, it cannot report too much information. Therefore, the terminal only reports the indication information and does not report measurement results or other information.

[0157] 3) If the terminal experiences an RLF in the source cell and then a DAPS handover failure occurs in the target cell, the terminal will perform cell selection and then initiate a reconstruction process.

[0158] Conditional handover is a mechanism to enhance the robustness of handover. The basic idea of ​​conditional handover is to address the problem of sudden channel degradation between the terminal and the serving cell (especially at high frequencies), which can prevent the terminal from completing the handover process normally. The base station can configure the terminal to trigger measurement reporting at a lower threshold, while including a higher threshold in the handover command (also known as the HO command). Furthermore, the handover command can also carry the random access resources used by the terminal in the target cell. Once the handover threshold is met, the terminal initiates a random access procedure to the target cell. Additionally, the source base station can configure conditional handover for the terminal for multiple target cells. When a conditional handover fails, the terminal performs cell selection. If the selected cell is a candidate cell for conditional handover, the terminal can use pre-configured resources to access the target cell; if the selected cell is not a candidate cell, the terminal executes a reconstruction procedure.

[0159] In summary, in related technologies, if a normal handover fails, the terminal performs cell reconstruction, resulting in a slow recovery of the RRC connection. Furthermore, the failure-related information (which may include the source cell identifier, target cell identifier, measurement results, etc.) is only reported to the network side after the terminal's RRC connection is established. Similarly, during conditional handover, if the conditional handover fails and the cell selected by the terminal is not a candidate target cell for the conditional handover, the terminal performs reconstruction, resulting in a slow recovery of the RRC connection. Again, the failure-related information is only reported to the network side after the terminal's RRC connection is established. During DAPS handover, if the terminal experiences an RLF in the source cell and / or a DAPS handover failure in the target cell, the terminal cannot promptly report the failure-related measurement information to the network side, thus preventing the network side from assisting the terminal in quickly restoring the RRC connection.

[0160] On the other hand, the same problems exist if the above technical solution is adopted for multi-connection scenarios.

[0161] Based on this, in various embodiments of this application, in multi-connection scenarios, the terminal reports information related to wireless connection failure to the master node through the secondary node; thus, the network side can help the terminal restore the RRC connection with the source base station and / or the target base station as soon as possible based on the information reported by the terminal, thereby improving the user experience.

[0162] This application provides an information reporting method, such as... Figure 2 As shown, the method includes:

[0163] Step 201: When the terminal determines that the wireless connection of the first cell or the first cell group has failed, it sends the first information to the auxiliary node;

[0164] Step 202: The auxiliary node receives the first information and sends the first information to the master node;

[0165] Step 203: The master node receives the first information sent by the terminal through the slave node;

[0166] The first information includes at least one of the following:

[0167] The relevant identifiers of the first residential area or the first group of residential areas;

[0168] The terminal measures the cell quality;

[0169] The second information indicates that the first cell is a primary cell or a primary-secondary cell, or that the first cell group is a primary cell group or a secondary cell group.

[0170] The third information represents the type of terminal switching or the type of failure when a wireless connection failure occurs.

[0171] In practical applications, the solution of this embodiment can be applied to multi-connection scenarios, meaning the terminal supports multiple connections. Furthermore, the multi-connection scenario can exist in the following two ways:

[0172] 1) The master node is switched over, and the terminal experiences an RRC connection failure in the source cell and / or the target cell;

[0173] 2) The primary node did not switch over, but the primary node or some of the secondary nodes experienced RRC connection failures.

[0174] It is understood that the connection quality between the terminal and the secondary node is higher than that between the terminal and the primary node. Thus, in multi-connection scenarios, regardless of whether a handover occurs, the terminal can report the connection failure information to the network side through the secondary node (which has better wireless connection quality than the primary node) when an RRC connection with the network side fails. This allows the network side to promptly help the terminal restore the RRC connection with the corresponding network-side node, thereby improving the user experience.

[0175] In practical applications, the terminal can also be called a user equipment (UE) or a user; the secondary node can also be called a secondary base station; the primary node can also be called a primary base station; in the event of a handover of the primary node, the primary node may include a source primary node and / or a target primary node; the source primary node can also be called a serving primary node, a source primary base station, or a serving primary base station; the target primary node can also be called a target primary base station.

[0176] In practical applications, the wireless connection failure includes RRC connection failure.

[0177] The first cell can be a primary cell; the first cell group can be a primary cell group. Here, in practical applications, when the primary cell in the first cell group fails to connect wirelessly, or when both the primary cell and the secondary cell in the first cell group fail to connect wirelessly, the terminal determines that the wireless connection of the first cell group has failed.

[0178] In step 201, for example, the terminal can send the first information to the secondary node through messages such as MCGFailure Information, XN SETUP REQUEST, and NG-RAN NODE CONFIGURATION UPDATE. This application embodiment does not limit this.

[0179] In practical applications, the relevant identifiers of a cell may include physical cell identifiers (PCI, Physical Cell Identifier), etc., but this application embodiment does not limit this.

[0180] In practical applications, the type of cell quality measurement results specifically included in the first information can be set according to requirements, and this application embodiment does not limit this. For example, the first information may include the quality of all cells measured by the terminal, or it may only include the quality of cells where wireless connection failure occurred, i.e., the quality of the first cell or the cells of the first cell group; furthermore, from another perspective, the cell quality may specifically include the quality of the source primary cell, the target primary cell, the primary and secondary cells on the secondary node, and the secondary cells, etc. The quality of the cells can be referred to as the signal quality of the cells.

[0181] When it is determined that the wireless connection of the first cell has failed, the first information includes at least one of the following:

[0182] The relevant signage for the first residential area;

[0183] The terminal measures the cell quality;

[0184] The second information indicates whether the first cell is a primary cell or a primary-secondary cell;

[0185] The third information represents the type of terminal switching or the type of failure when a wireless connection failure occurs.

[0186] When it is determined that the wireless connection of the first cell group has failed, the first information includes at least one of the following:

[0187] The relevant identifiers of the first group of communities;

[0188] The terminal measures the cell quality;

[0189] The second information indicates that the first cell group is a primary cell group or a secondary cell group.

[0190] The third information represents the type of terminal switching or the type of failure when a wireless connection failure occurs.

[0191] In practical applications, the relevant identifiers of the cells in the first cell group may include the PCIs of all cells in the first cell group, but this application embodiment does not limit this.

[0192] In one embodiment, the third information may include one of the following:

[0193] Normal handover, also known as handover in general;

[0194] Condition switching;

[0195] DAPS switching;

[0196] Switching based on DAPS and conditions, i.e., both DAPS and condition switching are configured simultaneously;

[0197] The connection to the master node, master cell group, or master cell failed.

[0198] The connection between the auxiliary node, auxiliary cell group, or primary and auxiliary cell failed.

[0199] Wherein, when it is determined that the wireless connection of the first cell or the first cell group has failed, and the third information represents the type of terminal handover when the wireless connection failure occurs, the third information may include one of the following:

[0200] Normal switching;

[0201] Condition switching;

[0202] DAPS switching;

[0203] Switching based on DAPS and conditions.

[0204] When it is determined that the wireless connection of the first cell has failed, and the third information represents the type of terminal failure when the wireless connection failure occurs, the third information may include one of the following:

[0205] The connection to the master node or master cell failed.

[0206] The connection between the secondary node and the primary / secondary cell failed.

[0207] When it is determined that the wireless connection of the first cell group has failed, and the third information represents the type of terminal failure when the wireless connection failure occurs, the third information may include one of the following:

[0208] Primary cell group connection failed;

[0209] The auxiliary cell group connection failed.

[0210] In practical applications, if the terminal experiences a wireless connection failure during condition switching, the auxiliary node can also report the triggering event (i.e. the satisfied event) and / or the threshold corresponding to the event to the master node.

[0211] Based on this, in one embodiment, where the type of terminal switching when the third information indicates a wireless connection failure includes conditional switching, the first information may further include:

[0212] The fourth information represents the triggering event and / or the corresponding threshold for condition switching.

[0213] For example, the fourth information may include A3 event, A5 event, and corresponding threshold values.

[0214] In step 202, in practical applications, when a switch occurs, after receiving the first information, the auxiliary node can send the first information to the source master node and / or the target master node.

[0215] Based on this, in one embodiment, when the first information includes the third information, sending the first information to the master node may include:

[0216] The auxiliary node sends the first information to the source master node and / or the target master node.

[0217] In practical applications, when the first information includes the third information and the cell quality measured by the terminal, the auxiliary node can choose to forward the first information to the source master node and / or the target master node based on the measurement results of the cell quality by the terminal.

[0218] For example, if the measurement result quality at the source master node is higher than that at the target master node, the auxiliary node may only forward the first information to the source master node because the success rate of the terminal successfully connecting to the target master node is low. Conversely, if the measurement result quality at the source master node is lower than that at the target master node, the auxiliary node may only forward the first information to the target master node. In this way, only the master node that receives the first information can reconfigure the wireless connection for the terminal.

[0219] In practical applications, for multi-connection scenarios, if some secondary nodes experience RRC connection failures, the secondary node with higher RRC connection quality (which has better wireless connection quality compared to the primary node and / or other secondary nodes) receives the first information reported by the terminal and forwards the first information to the primary node.

[0220] In step 203, in practical applications, the source master node and / or the target master node can negotiate with the auxiliary node to reconfigure the wireless connection of the terminal; in other words, the source master node and / or the target master node can determine the configuration for reconfiguring the wireless connection of the terminal by the auxiliary node, the source master node, or the target master node through information exchange with the auxiliary node.

[0221] Based on this, in one embodiment, the method may further include:

[0222] The auxiliary base station interacts with the source master node and / or the target master node to determine the configuration for the terminal to reconnect wirelessly by the auxiliary node, the source master node, or the target master node.

[0223] Here, when the master node only includes the source master node, the source master node can determine the configuration for the terminal to reconnect wirelessly by the auxiliary node or the source master node through information interaction with the auxiliary node.

[0224] In the case where the master node only includes the target master node, the target master node can interact with the auxiliary node to determine whether the auxiliary node or the target master node will reconfigure the wireless connection of the terminal.

[0225] When the master node includes a source master node and a target master node, the source master node, the target master node, and the auxiliary node can exchange information to determine the configuration for the terminal to reconnect wirelessly by the auxiliary node, the source master node, or the target master node.

[0226] In practical applications, if it is determined that the master node will reconfigure the wireless connection of the terminal, the master node needs to notify the auxiliary node that the source master node or the target master node will reconfigure the wireless connection of the terminal.

[0227] Based on this, in one embodiment, when the first information includes the third information and the master node reconfigures the wireless connection of the terminal, the method may further include:

[0228] The master node sends a sixth message to the slave node, the sixth message indicating that the master node reconfigures the wireless connection of the terminal; in other words, the sixth message indicates that the source master node or the target master node reconfigures the wireless connection of the terminal.

[0229] The auxiliary node receives the sixth message sent by the source master node or the target master node.

[0230] Here, if it is determined that the target master node will reconfigure the wireless connection of the terminal, the target master node may also notify the source master node to reconfigure the wireless connection of the terminal; if it is determined that the source master node will reconfigure the wireless connection of the terminal, the source master node may also notify the target master node to reconfigure the wireless connection of the terminal.

[0231] In practical applications, the criteria for determining whether the source master node or the target master node should reconfigure the wireless connection for the terminal can be set according to requirements.

[0232] For example, if the quality of one or more cells on the target master node side is higher than the quality of cells on the source master node side in the measurement results included in the first information, or if the quality of cells on the target master node side is similar to that on the source master node side, but the load of cells on the target master node side is lower, it can be determined that the target master node will reconfigure the wireless connection of the terminal, making it more likely that the terminal will restore the wireless connection of the master cell group.

[0233] For example, if a wireless connection fails when the terminal performs a conditional handover, it can be determined that the source master node will reconfigure the wireless connection for the terminal. Specifically, the source master node can configure a new conditional handover trigger event and / or corresponding threshold for the terminal, or configure information such as a new target master cell and access resources for the terminal.

[0234] When a terminal experiences a wireless connection failure at the source master node, it indicates that the terminal has switched over too late. The source master node can configure new conditional handover trigger events and / or corresponding thresholds based on the terminal's measurement results. For example, it can lower the a3-Offset parameter of the A3 event, or raise the a5-Threshold1 parameter and / or lower the a5-Threshold2 parameter of the A5 event, so that the terminal can switch to the target cell earlier. Alternatively, the source master node can also configure new target master cell and access resources for the terminal.

[0235] When a terminal fails to handover to the target primary node, it indicates that the terminal has switched over too early. The source primary node can configure new conditional handover trigger events and / or corresponding thresholds based on the terminal's measurement results. For example, it can increase the a3-Offset parameter of the A3 event, or decrease the a5-Threshold1 parameter and / or increase the a5-Threshold2 parameter of the A5 event, so that the terminal can switch to the target cell later. Alternatively, the source primary node can also configure new target primary cell and access resources for the terminal.

[0236] In practical applications, if it is determined that the auxiliary node will reconfigure the wireless connection of the terminal, the auxiliary node needs to notify the master node to reconfigure the wireless connection of the terminal by the auxiliary node.

[0237] Based on this, in one embodiment, when the first information includes the third information and the auxiliary node reconfigures the wireless connection of the terminal, the method may further include:

[0238] The auxiliary node sends a seventh message to the source master node and / or the target master node, the seventh message indicating that the auxiliary node reconfigures the wireless connection of the terminal.

[0239] The master node (i.e., the source master node and / or the target master node) receives the seventh message sent by the auxiliary node.

[0240] In practical applications, if the cell quality of the auxiliary node side in the measurement results contained in the first information is higher than the cell quality of the source master node and the target master node side, the auxiliary node can configure itself as a new master node, configure the primary and auxiliary cells or the auxiliary cell as a new master cell, and send the seventh information to the source master node and / or the target master node.

[0241] In practical applications, when the auxiliary node, source master node, or target master node determines, based on the measurement results contained in the first information, that the cell quality on the auxiliary node, source master node, and target master node sides is relatively poor (for example, the cell quality does not meet a preset condition, which indicates that the cell quality is good) or the cell load is too large (for example, greater than a preset threshold), it can be determined that the wireless connection established with the terminal needs to be released.

[0242] Based on this, in one embodiment, the method may further include:

[0243] The auxiliary node releases the wireless connection established with the terminal;

[0244] And / or,

[0245] The master node releases the wireless connection established with the terminal.

[0246] In practical applications, when it is determined that the master node will reconfigure the wireless connection of the terminal, the master node needs to indicate the new wireless connection configuration to the terminal through the auxiliary node or indicate the release of the connection established between the source master node and / or the target master node and the terminal.

[0247] Based on this, in one embodiment, when the master node reconfigures the wireless connection of the terminal, i.e., when the source master node or the target master node reconfigures the wireless connection of the terminal, the method may further include:

[0248] The master node (i.e., the source master node or the target master node) sends a fifth message to the terminal through the auxiliary node. The fifth message indicates a new configuration of the wireless connection or indicates the release of the connection established between the source master node and / or the target master node and the terminal.

[0249] The auxiliary node receives the fifth information sent by the source master node or the target master node, and sends the fifth information to the terminal;

[0250] The terminal receives the fifth message sent by the auxiliary node.

[0251] In practical applications, after receiving the fifth piece of information, the terminal can establish a wireless connection with the source master node or the target master node using the new wireless connection configuration, or perform cell reconstruction. If the terminal reconstructs back to the target cell of DAPS or conditional handover, the terminal can report in the reconstruction report or other reports that the target cell is the target cell of DAPS or conditional handover.

[0252] Correspondingly, embodiments of this application also provide an information reporting method, applied to a terminal, such as... Figure 3 As shown, the method includes:

[0299] In one embodiment, when the master node includes the target master node, the method may further include:

[0300] By interacting with the auxiliary node, it is determined whether the auxiliary node or the target master node will reconfigure the wireless connection of the terminal; or, by interacting with the auxiliary node and the source master node, it is determined whether the auxiliary node, the source master node, or the target master node will reconfigure the wireless connection of the terminal.

[0303] It should be noted that the specific processing procedure of the master node has been described in detail above and will not be repeated here.

[0304] The information reporting method provided in this application embodiment involves a terminal sending first information to a secondary node when it determines that the wireless connection to a first cell or a first cell group has failed. The secondary node receives the first information and sends it to a primary node. The primary node receives the first information sent by the terminal through the secondary node. The first information includes at least one of the following: a cell-related identifier of the first cell or the first cell group; cell quality measured by the terminal; second information, indicating that the first cell is a primary cell or a primary / secondary cell, or that the first cell group is a primary cell group or a secondary cell group; and third information, indicating the type of handover or failure of the terminal when the wireless connection fails. In a multi-connection scenario, the terminal reports relevant information about the wireless connection failure (i.e., the first information) to the primary node through the secondary node. Thus, the network side can help the terminal quickly restore the RRC connection with the corresponding network-side node based on the information reported by the terminal. Specifically, in the event of a handover of the primary node, if the terminal experiences an RLF (Relational Link Failure) in the source cell and / or the target cell, or if the handover fails, the terminal can report the failure information to the source base station and / or the target base station via a secondary base station to help the source base station and / or the target base station quickly restore the RRC (Relational Control Code) connection with the terminal. If the primary node has not undergone a handover, but the terminal's RRC connection with the primary base station or some secondary base stations fails, the terminal can report the failure information to the network side via a secondary base station with a better connection quality than the primary base station and other secondary base stations to help the terminal quickly restore the RRC connection with the primary base station or other secondary base stations, thereby improving the user experience.
