Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically to a method, apparatus, communication device, and storage medium for condition configuration. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) introduced a conditional configuration mechanism. When the channel between the User Equipment (UE) and the serving cell suddenly deteriorates (especially in high-frequency, high-speed scenarios), preventing the UE from completing the handover / PSCell addition and change process normally, the base station can configure the UE to trigger measurement reporting at a lower threshold. The source base station selects candidate base stations based on the information reported by the user and sends a handover / PSCell addition request to the candidate base stations. The conditional configuration command configures the determined candidate cell list to the user, carrying a higher threshold for triggering handover / addition and the random access resources used by the UE in the target cell. Once the handover threshold is met, the UE initiates a random access procedure to the target base station.

[0003] On the other hand, in future communication scenarios, mobile communication network nodes (including non-terrestrial network nodes in non-terrestrial networks (NTNs) such as satellites, hot air balloons, aircraft, or space stations, or terrestrial communication network nodes deployed in public transportation such as buses and subways) will distribute / forward data. Taking NTNs as an example, such as... Figure 1a As shown, non-terrestrial network nodes (such as satellite or UAS platforms) are connected to the gateway via a feeder link, and the UE is connected to the non-terrestrial network nodes via a service link. When a non-terrestrial network node moves, the Physical Cell Identity (PCI) changes for the UE when the service link (the link between the non-terrestrial network node and the UE) changes. Figure 1b As shown.

[0004] Applying conditional configuration to mobile communication network nodes presents challenges. If candidate cells are selected solely based on signal quality measurement results, the deviation can be significant. A solution for conditional configuration of rapidly moving network nodes is urgently needed. Furthermore, in the NTN architecture, the large transmission delay between the terminal and network node due to network node movement can lead to untimely configuration updates.

[0075] The candidate network node is either the network node where the cell corresponding to the currently allocated first PCI is located when the first conditional configuration request is issued, or the network node where the cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued, wherein the cell corresponding to the second PCI pre-allocates the first PCI.

[0076] In a seventh aspect, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the methods described in the first, second, or third aspects of the present invention.

[0077] Eighthly, embodiments of the present invention also provide a communication device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the methods described in the first, second, or third aspects of the present invention.

[0078] The present invention provides a method, apparatus, communication device, and storage medium for condition configuration. A serving network node determines at least one candidate network node and sends a first condition configuration request to the at least one candidate network node. The first condition configuration request requests the at least one candidate network node to send first condition configuration information. The first condition configuration information includes at least access resource information of the candidate cell. The serving network node receives the first condition configuration information sent by the at least one candidate network node, generates second condition configuration information based on each first condition configuration information, and sends at least one second condition configuration information to a terminal device. The second condition configuration information includes at least the first condition configuration information and execution condition information.

The terminal device accesses the target cell among the candidate cells based on the second condition configuration information and the access resource information of the candidate cells. The technical solution of this invention involves determining at least one candidate network node through a serving network node and sending a first condition configuration request to each candidate network node. This allows the first condition configuration information to be sent through each candidate network node. The serving network node then adds information (e.g., adds execution condition information) to the first condition configuration information to obtain second condition configuration information, which is then sent to the terminal device. Since the candidate network nodes may be network nodes that may be accessed in the future, this solution addresses the problem of condition configuration for rapidly moving network nodes. It avoids the situation where the network node accessed by the terminal may not be the same network node that was accessed when the condition configuration information was issued, thus rendering the condition configuration information inapplicable.

[0087] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0088] The technical solutions of this invention can be applied to various communication systems, such as GSM (Global System of Mobile communication), LTE (Long Term Evolution), or 5G systems. Optionally, a 5G system or 5G network can also be referred to as a New Radio (NR) system or NR network.

[0089] For example, the communication system used in this embodiment of the invention may include network devices and terminal devices (also referred to as terminals, communication terminals, etc.); the network device may be a device that communicates with the terminal device. The network device can provide communication coverage within a certain area and can communicate with terminals located within that area. Optionally, the network device may be a base station in various communication systems, such as an evolved Node B (eNB) in an LTE system, or a gNB in ​​a 5G or NR system.

[0090] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Communication devices may include network devices and terminals with communication functions. Network devices and terminal devices can be the specific devices described above, which will not be repeated here. Communication devices may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities. This embodiment of the present invention does not limit these.

[0091] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0092] This invention provides a method for condition configuration. Figure 2 A flowchart illustrating the condition configuration method according to an embodiment of the present invention is shown below; Figure 2 As shown, the method includes:

[0093] Step 101: The serving network node determines at least one candidate network node and sends a first condition configuration request to the at least one candidate network node; the first condition configuration request is used to request the at least one candidate network node to send first condition configuration information; the first condition configuration information includes at least the access resource information of the candidate cell;

[0094] Step 102: The service network node receives first condition configuration information sent by the at least one candidate network node, generates second condition configuration information based on each first condition configuration information, and sends at least one second condition configuration information to the terminal device; the second condition configuration information includes at least the first condition configuration information and execution condition information;

[0095] The candidate network node is either the network node where the cell corresponding to the currently allocated first PCI is located when the first conditional configuration request is issued, or the network node where the cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued, wherein the cell corresponding to the second PCI pre-allocates the first PCI.

[0096] In various embodiments of the present invention, a serving network node refers to a network node that provides network services to a terminal device, that is, the network node currently accessed by the terminal device. In other embodiments, the serving network node may also be referred to as a first network node. Candidate network nodes do not currently provide network services to the terminal device; some candidate network nodes are measurable by the terminal device, while others are not. In other embodiments, the candidate network node may also be referred to as a second network node. In this embodiment, the names of the serving network node and the candidate network node are not limited.

[0097] In this embodiment, the serving network node decides to perform condition configuration and sends a first condition configuration request to at least one candidate network node. For example, the first condition configuration request can be used for conditional handover (CHO) and / or conditional primary / secondary cell addition or change (CPAC).

[0098] In this embodiment, at least one candidate network node determined by the serving network node is either the network node where the cell corresponding to the currently allocated first PCI is located when the first conditional configuration request is issued, or the network node where the cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued. The cell corresponding to the second PCI pre-allocates the first PCI. That is, the candidate network node can be a network node that the terminal device can currently measure. When the serving network node issues the first conditional configuration request, the candidate cell on the candidate network node that receives the first conditional configuration request has been configured with the first PCI. Alternatively, the candidate network node can also be a network node that the terminal device cannot currently measure. The candidate network node may be about to pass by or access the terminal device. The candidate cell on the candidate network node has been configured with the second PCI and pre-allocated the first PCI. The first PCI will be configured when the terminal device is about to pass by or access the terminal device.

[0099] In some optional embodiments, the at least one candidate network node includes at least a first candidate network node and / or a second candidate network node; the first candidate network node is the network node where the currently allocated first PCI corresponding cell is located when the first conditional configuration request is issued, and the first candidate network node is a network node that the terminal device can measure; the second network node is the network node where the currently allocated second PCI corresponding cell is located when the first conditional configuration request is issued; the second candidate network node is a network node that the terminal device cannot currently measure; the step of sending the first conditional configuration request to the at least one candidate network node includes: the serving network node sending the first conditional configuration request to the first candidate network node and / or the second candidate network node respectively.

[0100] In this embodiment, the first candidate network node is a network node that the terminal device can currently measure. When the serving network node issues the first conditional configuration request, the candidate cell on the first candidate network node has already configured the first PCI. The second candidate network node is a network node that the terminal device has not currently measured. The second candidate network node may be about to pass by or access the terminal device. The candidate cell on the second candidate network node has already configured the second PCI and pre-allocated the first PCI. When the terminal device is about to pass by or access the terminal device, the first PCI will be configured. In this embodiment, the serving network node pre-determines a candidate network node that is about to pass by or access the terminal device (i.e., a network node that has pre-allocated the first PCI and has not yet been measured by the terminal device). When the first candidate node and / or the second candidate network node pass by a designated location (e.g., a location that the terminal device is about to reach), the terminal device can directly access the terminal device using the received second conditional configuration information, increasing the robustness of conditional handover / addition or change of primary and secondary cells.

[0101] In some optional embodiments of the present invention, the method further includes: the service network node receiving first information sent by the terminal device, the first information including at least one of the following: location information related to the terminal device, measurement results of the terminal device, a first request representing the terminal device requesting conditional configuration, and conditional configuration preferences.

[0102] In this embodiment, the terminal device reports first information, which may include at least one of the aforementioned information; in other embodiments, the first information may also be called auxiliary information, and the name of the information is not limited in this embodiment. The location information related to the terminal device is used to predict the movement trajectory of the terminal device, thereby assisting the serving network node in determining candidate network nodes (e.g., a second candidate network node).

[0103] In some optional embodiments of the present invention, the service network node determines at least one candidate network node by: the service network node determining at least one candidate network node based on the first information and / or pre-configuration information; the pre-configuration information includes at least one of the following: ephemeris information and transportation timetables related to the candidate network node.

[0104] In this embodiment, the serving network node can determine at least one candidate network node based on the first information and / or pre-configured information reported by the terminal device. The transportation timetable may include, for example, bus timetables, high-speed rail timetables, highway information, etc. The ephemeris information specifically refers to a satellite ephemeris. Optionally, the pre-configured information may include relevant information about network nodes near the serving network node, or it may be a complete satellite ephemeris. In this embodiment, the pre-configured information is not limited to including at least one piece of information from ephemeris information or transportation timetables related to candidate network nodes; it may also include any information capable of predicting the location of the terminal device and / or candidate network nodes, and this embodiment does not limit this.

[0105] In one example, the serving network node may determine conditional configuration based solely on pre-configuration information to identify at least one candidate network node. For example, it could determine at least one candidate network node based on nearby network nodes or satellite ephemeris data. In another example, the serving network node may also determine conditional configuration based on initial information reported by the terminal device, combined with pre-configuration information, to identify at least one candidate network node.

[0106] In some optional embodiments, the location information related to the terminal device includes multiple location point information; when the first information includes the location information related to the terminal device, the serving network node determines at least one candidate network node based on the first information and / or pre-configuration information, including: the serving network node determines a candidate network node that is about to pass through the first location information or a candidate network node that is about to connect with the terminal device based on the pre-configuration information; wherein, the first location information is location information determined based on the multiple location point information, indicating that the terminal device is about to arrive at a predetermined time.

[0107] In some optional embodiments, the method further includes: the service network node performing difference fitting on the plurality of location point information to determine the motion trajectory information of the terminal device; and determining the first location information that the terminal device is about to arrive at at a predetermined time based on the motion trajectory information.

[0108] In this embodiment, the service network node can perform difference fitting on multiple location points of the terminal device to determine the motion trajectory information of the terminal device, that is, to obtain the movement trend information of the terminal device; then, based on the motion trajectory information, it can determine the first location information that the terminal device will arrive at at a predetermined time. Furthermore, based on the pre-configured information, it determines candidate network nodes that will soon pass through the first location information or candidate network nodes that will soon connect to the terminal device, that is, it predicts candidate network nodes that will soon pass through the area where the first location information is located or candidate network nodes that will soon connect.

[0109] In some optional embodiments, the service network node receives first condition configuration information sent by the at least one candidate network node, including: the service network node receives the first condition configuration information sent by the at least one candidate network node through a switch request feedback message, a secondary network node change request feedback message, or a secondary node add request feedback message.

[0110] The aforementioned handover request feedback message is denoted as HANDOVER REQUEST ACKNOWLEDGE message; the aforementioned secondary network node change request feedback message is denoted as SgNB Modification Required ACKNOWLEDGE message; and the aforementioned secondary node addition request feedback message is SN Addition Request Ack message.

[0111] In some optional embodiments, sending a first condition configuration request to the at least one candidate network node includes: the serving network node sending a first condition configuration request to the at least one candidate network node via a switch request message, a secondary network node change request message, or a secondary node add request message.

[0112] Among them, the above-mentioned handover request message is denoted as HANDOVER REQUEST message; the above-mentioned secondary network node change request message is denoted as SgNB Modification Required message; and the above-mentioned secondary node addition request message is SN AdditionRequest message.

[0113] In some alternative embodiments, sending at least one second condition configuration information to the terminal device includes: the serving network node sending at least one second condition configuration information to the terminal device via an RRC reconfiguration message.

[0114] In some optional embodiments, the second condition configuration information further includes at least one of the following: the first PCI and the time configuration information of the second condition configuration information.

[0115] The time configuration information may include timer information (such as the timer's duration), valid time, or invalid time. For example, when a timer is started, the second condition configuration information becomes invalid when the timer's duration reaches the duration specified in the time configuration information; or the second condition configuration information is valid within the specified valid time and invalid outside of the specified valid time.

[0116] In some alternative embodiments, the execution condition information includes at least one of the following conditions:

[0117] The signal quality meets the requirements;

[0118] The terminal device enters the predetermined location;

[0119] The timer corresponding to the second condition configuration information times out;

[0120] Arrival at the scheduled time.

[0121] The timer timeout corresponding to the second condition configuration information indicates that the second condition configuration information has taken effect. For example, after receiving the second condition configuration information, the terminal device can start a timer, and upon timeout, begin accessing the target cell based on the second condition configuration information. In other embodiments, the timer timeout corresponding to the second condition configuration information can also be equivalent to being within the valid time range corresponding to the second condition configuration information.

[0122] Thus, by sending second condition configuration information carrying the execution condition information to the terminal device through the serving network node, the terminal device can access the target cell among the candidate cells when the above execution condition information is met.

[0123] Based on the above embodiments, this invention also provides a method for condition configuration. Figure 3 Flowchart of the method for condition configuration in embodiments of the present invention Figure 2 ;like Figure 3 As shown, the method includes:

[0124] Step 201: The candidate network node receives the first condition configuration request sent by the serving network node, and determines the candidate cell based on the first condition configuration request;

[0125] Step 202: The candidate network node sends first condition configuration information to the serving network node based on the first condition configuration request. The first condition configuration information includes at least access resource information about the candidate cell.

[0126] The candidate network node is either the network node where the cell corresponding to the currently allocated first PCI is located when the first conditional configuration request is issued, or the network node where the cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued, wherein the cell corresponding to the second PCI pre-allocates the first PCI.

[0127] In this embodiment, the candidate network node receives a first condition configuration request sent by the serving network node, and sends first condition configuration information based on the first condition configuration request; the first condition configuration information includes at least access resource information about the candidate cell, and the access resource information is used by the terminal device to access the cell according to the access resource information when the execution conditions are met.

[0128] In some alternative embodiments, the first condition configuration information may further include time configuration information of the first condition configuration information.

[0129] In this embodiment, when configuring the first condition configuration information, the candidate network node adds associated time configuration information. This time configuration information can be, for example, timer information, valid time, or invalid time. The time configuration information can be pre-agreed upon (e.g., according to a protocol) or predetermined based on the aforementioned pre-configured information (e.g., ephemeris information related to the candidate network node, transportation timetables, etc.). For example, when a timer is started, the corresponding first condition configuration information becomes invalid when the timer's duration reaches the duration of the time configuration information; or the first condition configuration information is valid within the aforementioned valid time and invalid outside of it.

[0130] In some optional embodiments of the present invention, the candidate network node is a first candidate network node, which is a network node that the terminal device can measure; or, the candidate network node is a second candidate network node, which is a network node that the terminal device cannot currently measure.

[0131] In this embodiment, the first candidate network node is a network node that the terminal device can currently measure. When the serving network node issues the first conditional configuration request, the network node containing the cell corresponding to the currently allocated first PCI is selected. For example, the first candidate network node can be a terrestrial network node connected to a mobile network node or a mobile network node itself. After receiving the first conditional configuration request from the serving network node, the first candidate network node uses the cell on its network as a candidate cell. The second candidate network node is a network node that the terminal device cannot currently measure. The second candidate network node may be about to pass by or access the terminal device. The candidate cell on the second candidate network node has a currently configured second PCI and pre-allocated the first PCI. When the terminal device is about to pass by or access the terminal device, the first PCI is configured. After receiving the first conditional configuration request from the serving network node, the second candidate network node uses the cell on its network as a candidate cell.

[0132] In some optional embodiments, when the candidate network node is the network node where the candidate cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued (that is, when the candidate network node is the aforementioned second candidate network node), the step of determining the candidate cell based on the first conditional configuration request includes: the candidate network node will determine the cell that will be accessed by the terminal device at a predetermined time as the candidate cell according to the pre-configuration information; wherein, the pre-configuration information includes at least one of the following: ephemeris information related to the candidate network node, and transportation timetable.

[0133] In this embodiment, optionally, the first condition configuration request may include a predetermined time and / or the first location information that the terminal device will arrive at at a predetermined time; then the candidate network node may determine the candidate cell that will arrive at the first location information at the predetermined time based on the pre-configured information (e.g., ephemeris information related to the candidate network node).

[0134] In some optional embodiments of the present invention, the candidate network node sends first condition configuration information to the serving network node based on the first condition configuration request, including: the candidate network node sends the first condition configuration information to the serving network node based on the first condition configuration request, a switching request feedback message, a secondary network node change request message, or a secondary node add request feedback message.

[0135] The aforementioned handover request feedback message is denoted as HANDOVER REQUEST ACKNOWLEDGE message; the aforementioned secondary network node change request feedback message is denoted as SgNB Modification Required ACKNOWLEDGE message; and the aforementioned secondary node addition request feedback message is SN Addition Request Ack message.

[0136] In some optional embodiments of the present invention, the candidate network node receiving the first condition configuration request sent by the serving network node includes: the candidate network node receiving the first condition configuration request sent by the serving network node through a switch request message, a secondary network node change request message, or a secondary node add request message.

[0137] Among them, the above-mentioned handover request message is denoted as HANDOVER REQUEST message; the above-mentioned secondary network node change request message is denoted as SgNB Modification Required message; and the above-mentioned secondary node addition request message is SN AdditionRequest message.

[0138] Based on the above embodiments, this invention also provides a method for condition configuration. Figure 4Flowchart of the method for condition configuration in embodiments of the present invention Figure 3 ;like Figure 4 As shown, the method includes:

[0139] Step 301: The terminal device receives at least one second condition configuration information sent by the serving network node, each second condition configuration information including at least execution condition information and first condition configuration information from the candidate network node; the first condition configuration information includes at least access resource information of the candidate cell; the first condition configuration information is sent by the candidate network node after receiving the first condition configuration request sent by the serving network node.

[0140] Step 302: When the execution condition information is met, the terminal device accesses the target cell among the candidate cells based on the access resource information of the candidate cells;

[0141] The candidate network node is either the network node where the cell corresponding to the currently allocated first PCI is located when the first conditional configuration request is issued, or the network node where the cell corresponding to the currently allocated second PCI is located when the first conditional configuration request is issued, wherein the cell corresponding to the second PCI pre-allocates the first PCI.

[0142] In this embodiment, the terminal device receives at least one second condition configuration information from a serving network node; each second condition configuration information corresponds to a candidate network node, that is, each second condition configuration information includes first condition configuration information issued by the corresponding candidate network node. Then, the terminal device evaluates whether the execution condition information included in each second condition configuration information is satisfied. After satisfying the execution condition information, it accesses the target cell among the candidate cells based on the access resource information of the candidate cell included in the corresponding second condition configuration information (specifically, the first condition configuration information). For example, the terminal device determines the target cell that meets the conditions among the candidate cells, and accesses the target cell after satisfying the execution condition information.

[0143] In some optional embodiments of the present invention, the at least one candidate network node includes at least a first candidate network node and / or a second candidate network node; the first candidate network node is the network node where the cell corresponding to the currently allocated first PCI is located when the first condition configuration request is issued; the second candidate network node is the network node where the cell corresponding to the currently allocated second PCI is located when the first condition configuration request is issued; the second condition configuration information further includes at least one of the following: the time configuration information of the first PCI and the second condition configuration information.

[0144] In some optional embodiments of the present invention, the execution condition information includes at least one of the following conditions:

[0145] The signal quality meets the requirements;

[0146] The terminal device enters the predetermined location;

[0147] The timer corresponding to the second condition configuration information times out;

[0148] Arrival at the scheduled time.

[0149] The timer timeout corresponding to the second condition configuration information indicates that the second condition configuration information has taken effect. For example, after receiving the second condition configuration information, the terminal device can start a timer, and upon timeout, begin accessing the target cell based on the second condition configuration information. In other embodiments, the timer timeout corresponding to the second condition configuration information can also be equivalent to being within the valid time range corresponding to the second condition configuration information.

[0150] In this embodiment, in one example, if the terminal device detects that the signal quality meets a condition (e.g., poor signal quality) through measurement, it can access the target cell according to the access resource information of the candidate cells carried in the second condition configuration information (or the first condition configuration information). In another example, when the terminal device enters a predetermined location, which may be, for example, the location that a mobile network node is about to arrive at at a specified time, the terminal device can access the target cell according to the access resource information of the candidate cells carried in the second condition configuration information (or the first condition configuration information).

[0151] In some optional embodiments, determining that the terminal device has entered a predetermined location includes: the terminal device determining that it will arrive at the predetermined location at a predetermined time based on pre-configuration information; wherein the pre-configuration information includes at least one of the following: ephemeris information related to candidate network nodes and transportation timetables.

[0152] In this embodiment, the time for a mobile network node to reach a predetermined location can be calculated by calculating the coordinates and time of adjacent coordinate points provided in the satellite ephemeris map; then, based on the location and speed information of the terminal device, it can be determined that the terminal device can reach the predetermined location within the time range; if it is determined that the terminal device will reach the predetermined location at the predetermined time, it can access the target cell at the corresponding time according to the second condition configuration information.

[0153] In some optional embodiments of the present invention, the time configuration information of the second condition configuration information includes the validity period of the second condition configuration information or the timing duration of the timer; the method further includes: after receiving the second condition configuration information, the terminal device starts a first timer corresponding to the second condition configuration information related to the first candidate network node when the second condition configuration information is related to the first candidate network node, and deletes the second condition configuration information when the first timer times out or reaches the corresponding first validity period; and / or, after receiving the second condition configuration information, the terminal device starts a second timer corresponding to the second condition configuration information related to the second candidate network node when the second condition configuration information is related to the second candidate network node, and measures the execution conditions corresponding to the second condition configuration information when the second timer times out or reaches the corresponding second validity period.

[0154] In this embodiment, as an example, when the candidate network node is the first candidate network node mentioned above, that is, the second conditional configuration information received by the terminal device is related to the first candidate network node; after receiving the second conditional configuration information, the terminal device starts a first timer corresponding to the second conditional configuration information related to the first candidate network node. When the first timer expires or reaches the first valid time corresponding to the first conditional configuration information, the first conditional configuration information is deleted. This avoids continuously measuring mobile network nodes that have been moved and avoids the accidental triggering of conditional configuration execution after switching to other network nodes and changing PCI. As another example, when the candidate network node is the second candidate network node mentioned above, that is, the second conditional configuration information received by the terminal device is related to the second candidate network node; after receiving the second conditional configuration information, the terminal device starts a second timer corresponding to the second conditional configuration information related to the second candidate network node. When the second timer expires or reaches the second valid time corresponding to the second conditional configuration information, the execution conditions corresponding to the second conditional configuration information are measured. This avoids prematurely measuring non-existent cells and reduces unnecessary measurement / measurement energy consumption.

[0155] In some optional embodiments of the present invention, the method further includes: the terminal device sending first information to the service network node, the first information including at least one of the following: location information related to the terminal device, measurement results of the terminal device, a first request representing the terminal device requesting conditional configuration, and conditional configuration preferences.

[0156] In some optional embodiments of the present invention, the method further includes: if the terminal device fails to access the target cell, it performs access to other candidate cells and records relevant information about the access failure.

[0157] In this embodiment, if the terminal device fails to access the target cell, the terminal device can access other candidate cells based on conditional configuration and record relevant information; the recorded relevant information may be required by the network management or network node, or it may be pre-agreed in the protocol.

[0158] In some optional embodiments, the information recorded regarding access failure includes at least one of the following: the PCI of the target cell, the reason for failure, the location information of the terminal device, and the time configuration information corresponding to the condition configuration information.

[0159] In this embodiment, the specific reasons for failure can be determined by combining location information, time, timer and other measurement conditions.

[0160] In some optional embodiments of the present invention, the method further includes: the terminal device sending the relevant information about the access failure to the current serving network node.

[0161] Optionally, the terminal device may report the relevant information regarding the access failure under one of the following conditions:

[0162] The terminal device is in a connected state;

[0163] The terminal device is in the process of transitioning to a connected state;

[0164] The terminal device is in an idle / inactive state.

[0165] Optionally, the information regarding access failure can be sent in a Radio Link Failure (RLF) report or a newly defined message. For example, the terminal device sending the access failure information to the current serving network node can be:

[0166] Requested from the network side;

[0167] Reported proactively by the terminal device;

[0168] The terminal device sends the log information at the request of the network side after informing the network side that there is relevant log information.

[0169] For example, if the time configuration information of the conditional configuration information is a valid time, but the configured valid time is too short, the configuration will be invalid when the conditional configuration is applied. The current service network node can receive the reconnetCellID in the RLF-report, which is a configured candidate cell. Therefore, the length of the valid time can be increased when configuring the time configuration information next time.

[0170] The technical solution of this invention involves determining at least one candidate network node through a serving network node and sending a first conditional configuration request to each candidate network node. This allows each candidate network node to send first conditional configuration information, which the serving network node then adds information to (e.g., adds execution condition information) to obtain second conditional configuration information, which is then sent to the terminal device. Since the candidate network nodes may be network nodes that will be accessed in the future, this solution addresses the problem of conditional configuration for rapidly moving network nodes, preventing the terminal from accessing a network node that is not the same as the one at the time the conditional configuration information was issued, thus rendering the conditional configuration information inapplicable. Furthermore, the time (validity period) of the conditional configuration information is configured accordingly to prevent handover / primary / secondary cell addition / change failures due to high latency transmission.
