Network-side equipment 12 may include access network devices or core network devices, of which access network devices may be called radio access network devices, radio access networks (RAN), radio access network functions, or radio access network units.Access network devices may include base stations, wireless local area network (WLAN) access points, or WiFi nodes, and base stations may be referred to as node B, advanced node B (eNB), access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home B node, home advanced B node, transmitting / receiving point (TRP), or any other appropriate term in the art, and the base station is not limited to any particular technical term as long as the same technical effect can be achieved. It should be noted that in the embodiments of this application, only base stations in an NR system are described as examples, and the specific types of base stations are not limited.

[0025] To make the embodiments of this application clearly understandable to those skilled in the art, they will first be described as follows.

[0026] 1. Conditional Handover (CHO). A conditional handover is defined as a handover that is executed when one or more handover execution conditions are met. The UE begins evaluating the execution conditions once the CHO setting is received and stops evaluating once the handover has started executing.

[0027] CHO principles: The CHO settings include the settings for the CHO candidate cells generated by the candidate gNB and the execution conditions generated by the source gNB.

[0028] A single execution condition may include one or two trigger conditions (CHO events A3 / A5). A single candidate cell supports only one reference signal (RS) type, and up to two different trigger quantities (e.g., Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ), signal-to-noise and interference ratio (SINR), etc.) can be set simultaneously.

[0029] If a Handover (HO) command is received before any CHO execution conditions are met, the UE will execute the HO procedure regardless of any previously received CHO settings.

[0030] When CHO is executed, that is, from the point when UE begins to synchronize with the target cell, UE stops detecting the source cell.

[0031] 2. Dual Connectivity (DC). Dual Connectivity means that the network provides resources from two network nodes / base stations (access network elements) to the UE, with one network node called the Master Node (MN) and the other called the Secondary Node (SN). Each network node can serve the UE with one cell, and carrier aggregation (CA) technology may be used, meaning that multiple serving cells controlled by the node may be configured for the UE. One or more cells controlled by a single node constitute a Cell Group (CG). The Master Cell Group (MCG) is controlled by the Master Node (MN), and the Secondary Cell Group (SCG) is controlled by the Secondary Node (SN). Each cell group contains one Special Cell (SpCell) and M Secondary Cells (Scell), where the value of M is currently [0, 31] in the NR, but this may be expanded in the future. Within the MCG, special cells are called Primary Cells (PCells), and within the SCG, special cells are called Primary Secondary Cells (PSCells).

[0032] In NR, if the SCG settings, including the ReconfigurationWithSync IE provided by the NW, are applied to the UE, and the UE successfully completes RACH in the candidate / target PSCell, then the UE's PSCell change is successful.

[0033] 3. Conditional Primary / Secondary Cell Change (CPC) process. The network (NW) pre-configures CPC settings for dual-connected UEs, and the UE evaluates whether the execution conditions are met. Once the execution conditions are met, the UE applies the pre-configured target secondary cell group (SCG) settings and performs PSCell modifications.

[0034] 4. Conditional Primary / Secondary Cell Addition (CPA). The method for setting up and executing CPA is similar to CPC, but when performing CPA evaluation, the trigger condition for applying SCG reset parameters is generally that the signal quality of the candidate / target PSCell exceeds a predetermined threshold for a predetermined period of time. At this time, since there is no serving PSCell yet, it is not possible to compare the signal quality of the candidate / target PSCell with the signal quality of the serving PSCell.

[0035] The current CHO and Conditional Primary / Secondary Cell Change / Addition (CPAC) are executed separately; that is, the CHO message does not include CPAC configuration information, so the current serving cell can never become a candidate PSCell. However, R18 studies cases where the CHO includes the target MCG and candidate SCG for CPC / CPA, so in such cases, the CHO configuration information may include CPA configuration information, and a UE that is originally single-connected or dual-connected can switch directly to DC mode when its CHO condition and corresponding CPA condition are met.

[0036] In R18, a serving cell (PCell / PSCell / SCells) before the UE executes CHO with CPAC (CHO message includes CPAC configuration information) may also be a candidate PSCell for a candidate PCell. In the current protocol, CPAC is only executed under the A4 (adjacent cell quality is above the threshold) and B1 (Inter-RAT adjacent cell is above the threshold) events, or the A3 (candidate adjacent cell quality for condition reset is equal to or better than the primary (SpCell) cell PCell / PSCell) and A5 (primary (SpCell) cell quality is below threshold 1, and candidate adjacent cell quality for condition reset is above threshold 2) events. It only focuses on situations where the adjacent cell is a candidate PSCell, but in situations where the serving cell (PSCell / PCell / SCell) is also a CPAC candidate cell, the UE cannot use these execution conditions, and this part of the configuration information becomes completely useless.

[0037] Similarly, with regard to candidate PCells, the current protocol only uses A3 (the quality of the candidate adjacent cell for condition reset is equal to or better than the primary (SpCell) cell PCell / PSCell) and A5 (the quality of the primary (SpCell) cell is less than or equal to threshold 1, and the quality of the candidate adjacent cell for condition reset is greater than or equal to threshold 2) events as execution conditions. It focuses only on situations where an adjacent cell becomes a candidate PCell, and similarly does not consider situations where a serving cell (PCell / PSCell / SCells) becomes a candidate PCell.

[0038] In the following, with reference to the drawings, the method for processing condition setting information provided in the embodiments of this application will be described in detail by referring to several embodiments and their application scenarios.

[0039] As shown in Figure 2, an embodiment of this application provides a method for processing condition setting information, which includes the following steps 201 and 202.

[0040] In step 201, the terminal obtains at least one set of first configuration information and a conditional handover execution condition, each set of first configuration information includes candidate primary cell configuration information for a conditional handover and / or at least one set of conditional primary secondary cell addition or modification CPAC configuration information, each set of CPAC configuration information includes configuration information for a candidate primary secondary cell corresponding to the candidate primary cell and a CPAC execution condition corresponding to the configuration information for the candidate primary secondary cell, the candidate primary cell includes the terminal's serving cell and / or the candidate primary secondary cell includes the terminal's serving cell.

[0041] The serving cell of the terminal includes the serving cell at the time the UE receives the first configuration information, and includes at least one of PCell, SCell, and PSCell.

[0042] Selectively, the terminal obtains at least one set of first configuration information and the conditions for performing a conditional handover from the first network-side equipment (source base station).

[0043] In step 202, the terminal determines the target execution conditions and / or target CPAC execution conditions for the conditional handover based on the first configuration information.

[0044] In the embodiments of this application, the terminal acquires at least one set of first configuration information and execution conditions for a conditional handover, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell, and the terminal determines the target execution conditions for a conditional handover and / or the target CPAC execution conditions based on the first configuration information, that is, it determines the target execution conditions and / or the target CPAC execution conditions corresponding to when the terminal's serving cell becomes a candidate primary cell or a candidate primary secondary cell, thereby achieving the objective of accurately processing the execution conditions corresponding to when the serving cell becomes a candidate primary cell or a candidate primary secondary cell, and furthermore, the terminal can subsequently perform condition evaluation based on the target execution conditions and / or target CPAC execution conditions, that is, if the target execution conditions and / or target CPAC execution conditions are met, it can execute the corresponding operation, such as CHO or CPAC or CHO with CPAC.

[0045] Here, the UE performing CHO with CPAC includes either: if the execution conditions for the candidate primary cell and the execution conditions for the corresponding candidate primary secondary cell are met, the UE performing a handover to the candidate primary cell and adding the candidate primary secondary cell; or if the execution conditions for the candidate primary cell are met but the execution conditions for the corresponding candidate primary secondary cell are not met, the UE performing a handover to the candidate primary cell.

[0046] As a selective implementation, if the candidate primary secondary cell corresponding to the candidate primary cell is the same cell as the serving cell of the terminal, the execution condition of the CPAC corresponding to the candidate primary secondary cell becomes the first execution condition. Here, the previous first execution condition is associated with the first trigger condition, and the previous first trigger condition is, The quality of the serving cells included in the condition setting information is above the first threshold, The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the third threshold, and the quality of the serving cells included in the condition setting information is above the fourth threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0047] The above first execution condition may be set by the candidate master base station or the candidate secondary base station.

[0048] In this implementation, if the candidate primary secondary cell corresponding to the candidate primary cell is the same cell as the terminal's serving cell, the network-side device sets the CPAC execution conditions corresponding to the candidate primary secondary cell as the first execution condition, allowing the terminal to determine the CPAC execution conditions for that serving cell.

[0049] As a selective implementation, if the candidate primary cell is the same cell as the serving cell of the terminal, the conditional execution condition corresponding to the candidate primary cell becomes the second execution condition. Here, the second execution condition is associated with the second trigger condition, and the second trigger condition is The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the third threshold, and the quality of the serving cells included in the condition setting information is above the fourth threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0050] Selectively, the second execution condition is set by the source base station.

[0051] In this implementation, if the candidate primary cell is the same cell as the terminal's serving cell, the network-side device sets the conditional execution condition corresponding to the candidate primary cell as the second execution condition, allowing the terminal to determine the conditional execution condition for that serving cell.

[0052] The step in which the terminal selectively determines the target CPAC execution conditions based on the first configuration information is: If the trigger condition associated with the CPAC execution condition is a third trigger condition, and the candidate primary / secondary cell corresponding to the CPAC execution condition is a serving cell, the step includes determining the trigger condition associated with the target CPAC execution condition as a fourth trigger condition. Here, the third trigger condition is that the quality of the candidate adjacent cell included in the condition setting information is equal to or greater than the fifth threshold, The quality of adjacent cells using different wireless access technologies (Inter-Radio Access Technology, Inter-RAT) included in the condition setting information must be above the 6th threshold, The quality of the candidate adjacent cells included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The condition includes at least one of the following: the quality of SpCell is below the 7th threshold, and the quality of candidate adjacent cells included in the condition setting information is above the 8th threshold. The fourth trigger condition is, The quality of the serving cells included in the condition setting information is equal to or greater than the 5th or 6th threshold, The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the 7th threshold, and the quality of the serving cells included in the condition setting information is above the 8th threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0053] The step of the terminal selectively determining the target execution conditions for the conditional handover based on the first configuration information is as follows: If the trigger condition associated with the conditional handover execution condition is a fifth trigger condition, and the candidate primary cell corresponding to the conditional handover execution condition is a serving cell, the step includes determining the trigger condition associated with the conditional handover execution condition as a sixth trigger condition. Here, the fifth trigger condition is, The quality of the candidate adjacent cells included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The condition includes at least one of the following: the quality of SpCell is below the 9th threshold, and the quality of candidate adjacent cells included in the condition setting information is above the 10th threshold. The sixth trigger condition is, The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the 9th threshold, and the quality of the serving cells included in the condition setting information is above the 10th threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0054] Selectively, after the step in which the terminal determines the target execution conditions and / or target CPAC execution conditions for the conditional handover based on the first configuration information, The procedure further includes the step of the terminal performing a condition evaluation based on the target execution conditions and / or target CPAC execution conditions.

[0055] In the embodiments of this application, after determining the target execution conditions and / or target CPAC execution conditions, condition evaluation can be performed according to conventional methods, and a detailed explanation is omitted here.

[0056] In the embodiments of this application, the terminal acquires at least one set of first configuration information and execution conditions for a conditional handover, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell, and the terminal determines the target execution conditions for a conditional handover and / or the target CPAC execution conditions based on the first configuration information, i.e., the target execution conditions and / or the target CPAC execution conditions corresponding to the case where the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to the case where the serving cell becomes a candidate primary cell or a candidate primary secondary cell.

[0057] What needs to be explained is that, in the embodiments of this application, the quality of a cell (serving cell or adjacent cell) can be expressed, for example, as the sum of the measurement result of the cell and one or more parameters set by the network, or as the difference between the measurement result of the cell and one or more parameters set by the network, wherein the parameters include at least one of an offset value corresponding to an event, a frequency point-specific offset value corresponding to a reference signal, and a cell-specific offset value corresponding to the cell. The measurement result of the cell includes the RSRP, RSRQ, or SINR of the reference information contained in the cell.

[0058] As shown in Figure 3, the embodiment of this application further provides a method for processing condition setting information, which includes the following step 301.

[0059] In step 301, the first network-side device transmits at least one set of first configuration information and a conditional handover execution condition, each set of first configuration information includes a candidate primary cell configuration information for a conditional handover and / or at least one set of conditional primary secondary cell addition or modification CPAC configuration information, each set of CPAC configuration information includes configuration information for a candidate primary secondary cell corresponding to the candidate primary cell and a CPAC execution condition corresponding to the configuration information for the candidate primary secondary cell, the candidate primary cell includes the terminal's serving cell and / or the candidate primary secondary cell includes the terminal's serving cell.

[0060] Selectively, the first network-side device is a source base station. The first network-side device transmits at least one set of first configuration information and the conditions for performing a conditional handover to the terminal.

[0061] In the embodiments of this application, a first network-side device transmits at least one set of first configuration information and conditional handover execution conditions, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell, and the terminal determines the target execution conditions for conditional handover and / or target CPAC execution conditions based on the first configuration information, i.e., the target execution conditions and / or target CPAC execution conditions corresponding to the case where the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to the case where the serving cell becomes a candidate primary cell or a candidate primary secondary cell.

[0062] Selectively, if the candidate primary secondary cell corresponding to the candidate primary cell is the same cell as the serving cell of the terminal, the CPAC execution condition corresponding to the candidate primary secondary cell becomes the first execution condition. Here, the previous first execution condition is associated with the first trigger condition, and the previous first trigger condition is, The quality of the serving cells included in the condition setting information is above the first threshold, The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the third threshold, and the quality of the serving cells included in the condition setting information is above the fourth threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0063] If the candidate primary cell is the same cell as the terminal's serving cell, the first network-side device sets a conditional execution condition corresponding to the candidate primary cell as the second execution condition. Here, the second execution condition is associated with the second trigger condition, and the second trigger condition is The quality of the serving cell included in the condition setting information must be equal to or better than the quality of the special cell SpCell, The SpCell quality is below the third threshold, and the quality of the serving cells included in the condition setting information is above the fourth threshold, and at least one of these conditions is met. The aforementioned condition setting information includes a set of first setting information and the corresponding conditional handover execution conditions.

[0064] Selectively, before the first network-side device transmits at least one set of first configuration information and the conditions for performing a conditional handover, The first network-side device sends a first message to the target base station to instruct the target base station to prepare for a conditional handover. The steps include obtaining a first response message transmitted by the target base station, which includes at least one set of first configuration information, The process further includes the step of obtaining the at least one set of first configuration information based on the first response message.

[0065] In the embodiments of this application, the first message may specifically be a handover request message, or of course, another message. After receiving the first message, the target base station (candidate MN) communicates with the candidate SN and obtains the configuration information of the candidate primary secondary cell transmitted by the candidate SN. Selectively, the CPAC execution conditions corresponding to the candidate primary secondary cell may be determined by the candidate SN or the candidate MN.

[0066] Selectively, the first message includes a candidate cell recommended by the first network-side device, the recommended candidate cell includes at least one of a candidate primary cell and a candidate primary secondary cell, and the candidate cell is a different cell from the terminal's serving cell.

[0067] Selectively, at least one of the candidate primary cell and the corresponding candidate primary secondary cell in each set of first configuration information transmitted by the target base station is selected by the second network-side device from the candidate cells recommended by the first network-side device. Here, the second network-side equipment includes at least one of the target base station, a candidate MN corresponding to the target base station, and a candidate SN determined by the candidate MN corresponding to the target base station.

[0068] After the step of selectively obtaining the first response message transmitted by the target base station, If at least one of the candidate primary cell and the candidate primary secondary cell corresponding to the candidate primary cell in the target first setting information included in the first response message is a serving cell, the first network-side device further includes the step of discarding the first response message or discarding the target first setting information in the first response message.

[0069] After the step of selectively obtaining the at least one set of first configuration information based on the first response message, If the first candidate primary cell in the first configuration information is the same cell as the serving cell of the terminal, the first network-side device further includes the step of not setting conditions for performing a conditional handover for the first candidate primary cell and sending denial information to the third network-side device to instruct it to release the resource. Here, the third network-side equipment includes a candidate MN corresponding to the target base station.

[0070] In the embodiments of this application, a first network-side device transmits at least one set of first configuration information and conditional handover execution conditions, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell, and the terminal determines the target execution conditions for conditional handover and / or target CPAC execution conditions based on the first configuration information, i.e., the target execution conditions and / or target CPAC execution conditions corresponding to the case where the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to the case where the serving cell becomes a candidate primary cell or a candidate primary secondary cell.

[0071] As shown in Figure 4, the embodiment of this application further provides a method for processing condition setting information, which includes the following steps 401 and 402.

[0072] In step 401, the third network-side device receives a first message sent by the first network-side device instructing the third network-side device to prepare for a condition handover.

[0073] In step 402, the third network-side device transmits a first response message to the first network-side device based on the first message, the first response message comprising at least one set of first configuration information, each set of first configuration information comprising one set of candidate primary cell configuration information for a conditional handover and / or at least one set of conditional primary secondary cell addition or modification CPAC configuration information, each set of CPAC configuration information comprising configuration information for a candidate primary secondary cell corresponding to the candidate primary cell and CPAC execution conditions corresponding to the configuration information for the candidate primary secondary cell, the candidate primary cell comprising the terminal's serving cell and / or the candidate primary secondary cell comprising the terminal's serving cell.

[0074] Selectively, the third network-side equipment described above is a candidate MN corresponding to the target base station.

[0075] In the embodiments of this application, a third network-side device receives a first message transmitted by a first network-side device, and based on the first message, transmits a first response message to the first network-side device, thereby causing the first network-side device to transmit at least one set of first configuration information and conditional handover execution conditions to the terminal based on the first response message, and the terminal determines the target execution conditions and / or target CPAC execution conditions for conditional handover based on the first configuration information, that is, determines the target execution conditions and / or target CPAC execution conditions corresponding to when the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to when the serving cell becomes a candidate primary cell or a candidate primary secondary cell.

[0076] The step of selectively having a third network-side device send a first response message to the first network-side device based on the first message is: The third network-side device selects at least one candidate primary cell based on the first message, The third network-side device sets CPAC configuration information for the candidate primary secondary cell corresponding to each selected candidate primary cell, A step of obtaining at least one set of first configuration information based on the configuration information of the candidate primary cell, the configuration information of the candidate primary secondary cell corresponding to the candidate primary cell, and the CPAC configuration information. The procedure includes the step of sending a first response message containing the first configuration information to a first network-side device.

[0077] Selectively, the configuration information for the candidate primary secondary cell corresponding to the above candidate primary cell is transmitted to the third network-side equipment by the candidate SN.

[0078] Selectively, the first message includes a candidate cell recommended by the first network-side device, the recommended candidate cell includes at least one of a candidate primary cell and a candidate primary secondary cell, and the candidate cell is a different cell from the terminal's serving cell. The step of selecting at least one candidate primary cell is, The process includes selecting a candidate primary cell from among the candidate cells recommended by the first network-side device.

[0079] The step of selectively configuring CPAC configuration information for the candidate primary secondary cell corresponding to each selected candidate primary cell in the third network-side device is as follows: If the candidate primary secondary cell corresponding to the candidate primary cell is a different cell from the terminal's serving cell, the third network-side device includes the step of setting CPAC configuration information for the candidate primary secondary cell corresponding to the candidate primary cell.

[0080] Selectively, the first message includes identifier information of the terminal's serving cell. After the third network-side device selects at least one candidate primary cell based on the first message, if the second candidate primary secondary cell corresponding to the candidate primary cell is the same cell as the terminal's serving cell, the third network-side device further includes the step of not setting CPAC configuration information for the second candidate primary secondary cell and sending release information to the candidate SN corresponding to the second candidate primary secondary cell to instruct the candidate SN to release the resource.

[0081] In embodiments of the present application, a third network-side device receives a first message transmitted by a first network-side device instructing the third network-side device to prepare for a conditional handover; the third network-side device transmits a first response message to the first network-side device based on the first message, the first response message containing at least one set of first configuration information, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell; the terminal determines the target execution conditions and / or target CPAC execution conditions for a conditional handover based on the first configuration information, i.e., the target execution conditions and / or target CPAC execution conditions corresponding to the case where the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to the case where the serving cell becomes a candidate primary cell or a candidate primary secondary cell.

[0082] The method for processing condition setting information in this application will be explained below with reference to specific examples.

[0083] In a first specific embodiment of this application, a first execution condition is defined that is associated with a serving cell, and is set by the network only if the serving cell is a candidate primary secondary cell. The first execution condition is associated with N first trigger conditions, each of which is associated with a condition event A1 (condEvent A1) or a condition event similar to A1 (condEvent A1-like), the definitions of condEvent A1 and condEvent A1-like are shown in Table 1. [Table 1]

[0084] Here, Ms is the measurement result of the serving cell (without considering any offsets), Ofs is the offset amount for serving cell measurement events, and Ocs is the offset amount specific to the serving cell. Both are set by RRC, and if not set by RRC, they are set to 0. Hys is the hysteresis parameter of the serving cell measurement event, set by RRC. For RSRP, Ms is expressed in dBm, while for RSRQ and RS-SINR, Ms is expressed in dB. Ofs, Ocs, and Hys are expressed in dB, and Thresh is expressed in the same units as Ms.

[0085] Selectively, the setting information for the first trigger condition includes the first trigger time in addition to the parameters defined above.

[0086] With respect to execution conditions associated with CPA or CPC, if a first execution condition is included, if the measurement result of the serving cell satisfies the entry conditions of the event associated with the trigger condition included in the first execution condition within the first trigger time, the serving cell is deemed to have satisfied the trigger condition. If the measId corresponding to the trigger condition is modified / deleted or ceases to exist, or if the serving cell's measurement result satisfies the exit condition of the event associated with the trigger condition within the first trigger time, the serving cell is deemed not to satisfy the trigger condition. If a serving cell satisfies all the trigger conditions included in the first execution condition, the serving cell is considered to have satisfied the first execution condition.

[0087] As shown in Figure 5, the method of the embodiment of this application includes the following steps 501 to 506.

[0088] In step 501, the source base station sends a first message to one or more candidate base stations instructing the target base station to prepare CHO with CPAC.

[0089] Selectively, if the source base station and UE support CHO with CPAC, perform step 501 above.

[0090] Selectively, the first message may be a handover request message, or it may be any other message. If the first message is a handover request message, it may be explicitly indicated that the handover request message is for CHO with CPAC (for example, by adding instructional information indicating CHO with CPAC to the message), or it may be implicitly indicated (for example, by including configuration information associated with CPAC in the message).

[0091] Selectively, the first message includes candidate PCell(s) and / or PSCell(s) recommended by the source base station. Selectively, the first message includes a cell identifier for the UE's current serving cell (PCell, PSCell, and / or SCell), which may be one or more of a frequency point, PCI, or serving cell ID.

[0092] In step 502, the candidate target base station 1 (first MN) performs access control, and the first MN selects a candidate SN(s) for each PCell associated with it and communicates with the candidate SN(s).

[0093] The first MN or first SN sets execution conditions for a candidate PSCell associated with a candidate Pcell, and the first SN is an SN associated with a candidate PSCell.

[0094] Here, the interaction process between the first MN and the first SN includes the first MN sending an SN Addition Request to the first SN, and the first SN sending an SN Addition Request Acknowledge to the first MN.

[0095] Selectively, if the cell identifier of the PSCell included in the first response message of the candidate SN (first SN) is the same as that of the serving cell, the first MN determines the execution condition corresponding to the PSCell configuration information as the first execution condition, and the first response message includes the candidate PSCell configuration information sent to the first MN by the first SN.

[0096] If the cell identifier of a candidate PSCell selected by the first SN is the same as that of the serving cell, the first SN determines the execution condition corresponding to the PSCell's configuration information as the first execution condition.

[0097] In step 503, the first MN sends a response message to the source base station.

[0098] The response message transmitted by the first MN to the source base station may be a HANDOVER REQUEST ACKNOWLEDGE message, which includes one or more sets of CHO with CPAC configuration information, the one set of CHO with CPAC configuration information including configuration information for one candidate PCell cell, and configuration information and CPAC execution conditions for one or more candidate PSCell(s) associated with the candidate PCell cell, and optionally, the one set of CHO with CPAC configuration further includes configuration information for other MCG / SCG Scells in the target MCG and / or target SCG.

[0099] In step 504, the source base station sends RRC reconfiguration information to the UE, which includes one or more sets of CHO with CPAC configuration information and CHO execution conditions.

[0100] Here, one RRC reconfiguration piece of information includes one set of CHO with CPAC configuration information, or all of the CHO with CPAC configuration information included in the response information transmitted by one candidate target base station, or all of the CHO with CPAC configuration information included in the response information transmitted by all candidate target base stations.

[0101] In step 505, the UE sends an RRC reconfiguration complete message to the source base station.

[0102] Here, the UE sends an RRC reset complete message to the source base station to notify the source base station that it has received the RRC reset information. The UE stores the RRC reset message.

[0103] Step 505 is an optional step.

[0104] In step 506, the UE begins evaluating the CHO with CPAC conditions.

[0105] Specifically, step 506 includes at least one of the following:

[0106] First, the UE first evaluates the CHO execution conditions of all set candidate cells, and if one or more candidate cells meet the CHO execution conditions, the UE recognizes these candidate cells that meet the CHO execution conditions as the first candidate cells. The UE then evaluates the execution conditions of the candidate PSCell corresponding to the first candidate cell. If the candidate PSCell of the first candidate cell satisfies the CPAC execution conditions, the UE considers the first candidate cell and its associated candidate PSCell as a set of trigger cells. Secondly, the UE evaluates the CHO execution conditions for all set candidate cells and the CPAC execution conditions for the candidate PSCells corresponding to all CHO candidate cells. If a CHO candidate cell and at least one corresponding candidate PSCell satisfy the CPAC execution conditions, the UE designates the candidate cell that satisfies the CHO execution conditions and the associated candidate PSCell that satisfies the conditions as a set of trigger cells. If, selectively, only the CHO execution conditions of a candidate cell are met and there is no corresponding candidate PSCell that satisfies the CPAC execution conditions, the UE arbitrarily selects one candidate PCell that satisfies the execution conditions as the target PCell.

[0107] If there is only one set of trigger cells, the UE will execute the CHO with CPA procedure on it. If there are multiple sets of trigger cells, the UE will select any one set of trigger cells and execute the CHO with CPA procedure on it.

[0108] In a second specific embodiment of this application, if the protocol determines / the network sets the CPAC execution conditions included in the CHO condition reset for a candidate PSCell to be A4 / B1, and the candidate PSCell corresponding to the CPAC execution conditions is the current serving cell, the UE recognizes that A4 / B1 means the quality of the serving cell is above a threshold, i.e., A4 is A4&A1 and B1 is B1&A1, and as shown in Table 2, when evaluating the execution conditions, the UE applies some or all of the parameters corresponding to the execution conditions associated with A4 / B1 set by the network. [Table 2]

[0109] Regarding candidate PCell or candidate PSCell, If the CHO execution conditions or CPAC execution conditions included in the CHO condition reset or CPAC condition reset are determined by the protocol and set by the network to be A3 / A5, and the candidate PCell corresponding to the said CHO execution conditions is the current serving cell, the UE recognizes that A3 / A5 means A3&A1 or A5&A1. [Table 3]

[0110] The relevant parameters in Tables 2 and 3 have already been explained in the corresponding descriptions in Table 1, and will not be explained again here.

[0111] In a third specific embodiment of this application, a first execution condition is defined that is associated with a serving cell, and is set by the network only if the serving cell is a candidate primary secondary cell. The first execution condition is associated with N first trigger conditions, each of which is associated with a condition event A1 (condEvent A1) or a condition event similar to A1 (condEvent A1-like), the definitions of condEvent A1 and condEvent A1-like are shown in Table 1.

[0112] The method of this embodiment includes the following steps 601 and 602.

[0113] In step 601, the source base station sends a first message to one or more candidate base stations instructing the target base station to prepare CHO with CPAC.

[0114] In step 602, candidate target base station 1 (first MN) performs access control, selects a candidate SN(s) for each associated PCell, interacts with the candidate SN(s), recognizes the node corresponding to candidate target base station 1 as the first MN, and sets the corresponding CPAC configuration information for each selected PCell.

[0115] Here, the interaction process between the first MN and the first SN includes the first MN sending an SN Addition Request to the first SN, and the first SN sending an SN Addition Request Acknowledge to the first MN.

[0116] Selectively, if the cell identifier of a PSCell included in the first response message of a candidate SN (first SN) is the same as that of a serving cell, the first MN discards the configuration information of the candidate PSCell and sends rejection information to the candidate SN indicating the reason for rejection that it is the same cell as the serving cell. After receiving the rejection message, the candidate SN releases the corresponding resource. The first response message includes the configuration information of the candidate PSCell sent to the first MN by the first SN.

[0117] In a fourth specific embodiment of this application, the method includes the following steps 701 and 702.

[0118] In step 701, the source base station sends a first message to one or more candidate base stations instructing the target base station to prepare for CHO with CPAC.

[0119] Step 701 is the same as step 501 above.

[0120] If the first message contains candidate PCell(s) and / or PSCell(s) recommended by the source base station, protocol determination / network configuration / network implementation ensure that the recommended candidate PCell(s) and / or PSCell(s) included in the first message do not contain serving cells.

[0121] In step 702, the candidate MN transmits the recommended PSCell(s) to the candidate SN, and when the candidate SN determines the PSCell(s), it can select candidate PSCell(s) only from the recommended candidate PSCell(s) included in the first message, and / or the candidate MN corresponding to the candidate target base station can select candidate PSCell(s) only from the recommended candidate PSCell(s) included in the first message when determining the PSCell(s).

[0122] In a fifth specific embodiment of this application, a second execution condition is defined that is associated with a serving cell and is set by the network only if the serving cell is a candidate primary cell. The second execution condition is associated with N second trigger conditions, each of which is associated with a condition event similar to A1 (condEvent A1-like), the definition of which is shown in Table 4. [Table 4]

[0123] Here, Ms is the measurement result of the serving cell (candidate PCell) (no offset is considered), Mp is the measurement result from SpCell (without considering any offsets), Mn is the measurement result of adjacent cells (without considering any offsets), Ofs is the offset amount for serving cell measurement events, and Ocs is the offset amount specific to the serving cell. Both are set by RRC, and if not set by RRC, they are set to 0. Ofp is the offset amount for primary cell measurement events, and Ocp is the primary cell-specific offset amount. Both are set by the RRC, and if not set by the RRC, they are set to 0. Ofn is the offset amount for neighboring cell measurement events, and Ocn is the offset amount specific to neighboring cells. Both are set by RRC, and if not set by RRC, they are set to 0. Hys is the hysteresis parameter for this event, set by RRC, and Off is the offset parameter for this event, also set by RRC. For RSRP, Ms and Mp are expressed in dBm, or for RSRQ and RS-SINR, Ms and Mp are expressed in dB. Ofs, Ocs, Hys, Ofp, Ocp, and off are expressed in dB, and Thresh is expressed in the same units as Ms / Mp.

[0124] The method includes the following steps 801 and 802.

[0125] In step 801, the source base station sends a first message to one or more candidate base stations requesting the preparation of CHO with CPAC or CHO. In step 802, the candidate target base station performs access control, sends a CHO request to the candidate PCell cell controlled by it, sets execution conditions for each candidate PCell cell, If the candidate PCell cell identifier is the same cell as the serving cell, the candidate target base station determines the execution conditions corresponding to the candidate PCell cell as the second execution conditions.

[0126] In the embodiments of this application, the terminal acquires at least one set of first configuration information and execution conditions for a conditional handover, wherein the candidate primary cell in the first configuration information includes the terminal's serving cell, and / or the candidate primary secondary cell in the first configuration information includes the terminal's serving cell, and the terminal determines the target execution conditions for a conditional handover and / or the target CPAC execution conditions based on the first configuration information, i.e., the target execution conditions and / or the target CPAC execution conditions corresponding to the case where the terminal's serving cell becomes a candidate cell, thereby achieving the objective of accurately processing the execution conditions corresponding to the case where the serving cell becomes a candidate primary cell or a candidate primary secondary cell.
