Detailed Description
Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
1. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In order to clearly understand the technical solutions provided by the embodiments of the present application, the following describes a procedure of performing conditional switching by a terminal in the related art.
Referring to fig. 1, a timing diagram of a terminal performing a conditional switch in the related art may include the following steps:
step 101: and the source cell performs measurement configuration for the UE, and at least comprises the measurement configuration of condition 1 for triggering the conditional handover.
Step 102: the UE performs measurements according to the measurement configuration.
Step 103: and the UE determines that the neighbor cell measurement result meets the condition 1, and triggers a measurement report to report the neighbor cell measurement result meeting the condition 1 to the source cell.
Step 104: and the source cell allocates a pre-configured target cell for the UE according to the measurement report.
Step 105: and the source cell sends a switching request to each pre-configured target cell, wherein the switching request message carries the instruction information of conditional switching.
In practice, the source cell may allocate a plurality of pre-configured target cells to the UE according to the measurement report.
Step 106: and the target cell decides to admit the UE and generates a conditional switching command for the UE.
Step 107: the target cell sends a switching request response carrying a switching command to the source cell.
Step 108: and the source cell sends an RRC message carrying the conditional switching command and the switching execution condition to the UE.
Step 109: the UE sends an RRC complete message to the source cell.
Step 110: and the UE measures the pre-configured cell configured by the source cell and determines that the pre-configured cell meets the triggering condition of the conditional execution of the handover.
Step 111: the UE synchronizes and triggers the random access process to access a pre-configured cell which meets the triggering condition of executing the switching, namely a target access cell.
Step 112: and the UE sends a switching completion message to the target access cell to complete the switching process.
Step 113: and the target access cell sends a UE context release notice to the source cell.
In the related art, the network side may allocate a plurality of preconfigured cells to the UE, and allocate a trigger condition for performing conditional handover to each preconfigured cell. The network side device may configure a trigger measurement quantity, such as RSRP, RSRQ, or SINR, for each trigger condition for performing conditional handover. And the UE judges whether the pre-configured cell meets the triggering condition for executing the condition switching or not based on the triggering measurement quantity result. The RSRP, RSRQ, and SINR are different measurement types, respectively, and have no comparability. When the network side allocates a plurality of preconfigured target cells for the UE and the plurality of preconfigured target cells satisfy the condition of performing conditional handover, how the UE determines the evaluation measurement quantity between the candidate cells to select the target cell for access still remains to be solved.
Based on the above requirement, an embodiment of the present application provides a method for determining a target cell. The method can be implemented in two ways. First, when the network side device configures measurement information for the terminal, the measurement information may conform to a certain criterion, so that the terminal determines, according to the measurement information, an estimated measurement amount between target cells that satisfy an access trigger condition. And the terminal evaluates the measurement result of the target cell meeting the access triggering condition according to the determined evaluation measurement quantity to determine the target cell.
Secondly, after the network side device configures the measurement information for the terminal, the terminal may determine the evaluation measurement amount meeting the specified requirement. And evaluating the measurement result of the target cell meeting the access triggering condition according to the determined evaluation measurement quantity to determine the target cell.
In the method, the network side device can configure the measurement information for the terminal, so that the terminal can determine the evaluation measurement amount according to the measurement information, or the terminal can determine the evaluation measurement amount according to the specified requirement, and the terminal evaluates the measurement result of the target cell meeting the access triggering condition according to the evaluation measurement amount to determine the target cell.

In implementation, the measurement information determined by the network side device may include part or all of the following: triggering measurement quantity, evaluation measurement quantity and priority of the evaluation measurement quantity of the access triggering condition of each pre-configured cell. The following is a detailed description based on the above.
Mode 1: the measurement information includes trigger measurement quantities of access trigger conditions for each pre-configured cell.
1) And the network side equipment configures the same trigger measurement quantity for all the pre-configured cells belonging to the same priority in the access trigger condition configuration.
In implementation, the network side device may configure an access trigger condition for the preconfigured Cell, that is, a trigger condition for performing conditional handover, or a trigger condition for performing access during adding of a Secondary Cell Group (SCG) or changing of a Primary SCG Cell (PSCell). And trigger measurements need to be configured for one access trigger condition. And the UE judges whether the pre-configured cell meets the access triggering condition or not based on the measurement result of the triggering measurement quantity.
For example, the preconfigured cell allocated by the network side device for the terminal includes cell1, cell2, and cell3, where cell1 and cell2 belong to the same priority, and cell3 has a lower priority than cell1 and cell 2. The network side device configures the same trigger measurement quantity when configuring the access trigger conditions of the cell1 and the cell 2. For example, the trigger measurement quantities configured for the access trigger conditions of cell1 and cell2 are both RSRQ, and the trigger measurement quantity configured for the access trigger condition of cell3 is RSRP.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures RSRQ of cell1 and cell2, and measures RSRP of cell 3. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, and determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell 2. And the terminal determines that the cell3 does not meet the access triggering condition according to the RSRP result of the cell 3. Since the target cells meeting the access triggering condition are two cells 1 and 2, the terminal needs to determine the target cells from the cells 1 and 2.
Therefore, the terminal determines the same trigger measurement quantity contained in the high-priority preconfigured cell in the measurement information configured on the network side as the evaluation measurement quantity. Since the trigger measurement quantities in the access trigger conditions of cell1 and cell2 are both RSRQ, the terminal determines RSRQ as the evaluation measurement quantity. Then, the terminal evaluates the cell quality of cell1 and cell2 according to the RSRQ result, i.e., evaluates the RSRQ measurement results of cell1 and cell2, and determines the target cell. For example, if the terminal determines that the signal quality of the cell1 is higher than that of the cell2 according to the RSRQ result, the terminal determines that the cell1 is the target cell.
2) And the network side equipment configures the trigger measurement quantities for all the pre-configured cells belonging to the same priority level in the access trigger condition configuration, wherein the trigger measurement quantities comprise the same trigger measurement quantity.
The network side device may configure an access trigger condition, that is, a trigger condition for performing conditional handover, for the preconfigured Cell, or a trigger condition for performing access in a Secondary Cell Group (SCG) addition or Secondary Cell Group master Cell (PSCell) change process. And a plurality of access trigger conditions can be configured for one preconfigured cell, a plurality of trigger measurement quantities can be configured for one preconfigured cell. And the UE judges whether the pre-configured cell meets the access triggering condition or not based on the measurement result of the configured triggering measurement quantity.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell 3. Wherein, cell1 and cell2 belong to the same priority, and the priority of cell3 is lower than the priorities of cell1 and cell 2. When the network side device configures the access trigger conditions of the cell1 and the cell2, the configured trigger measurement quantities need to include the same trigger measurement quantities. For example, the trigger measurement quantity configured for the access trigger condition configured for the cell1 is RSRQ, the trigger measurement quantity configured for the access trigger condition configured for the cell2 is SINR and RSRQ, and the trigger measurement quantity configured for the access trigger condition configured for the cell3 is RSRP.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures RSRQ results for cell1, SINR and RSRQ results for cell2, and RSRP results for cell 3. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that cell1 meets the access triggering condition according to the RSRQ result of cell1, determines that cell2 meets the access triggering condition according to the RSRQ result of cell2, and determines that cell2 meets the access triggering condition according to the SINR result of cell 2. And the terminal determines that the cell3 meets the access triggering condition according to the RSRP result of the cell 3. Since the target cells meeting the access triggering conditions are three cells 1, 2 and 3, the terminal needs to determine the target cells from the cells 1, 2 and 3.
Therefore, the terminal determines the same trigger measurement quantity contained in the access trigger condition of the high-priority preconfigured cell in the measurement information configured on the network side as the evaluation measurement quantity. Since the cell1 and the cell2 have higher priority than the cell3, the terminal selects a target access cell among the cells of cell1 and cell 2. Since the access trigger condition of the cell1 and the access trigger condition of the cell2 both have the trigger measurement RSRQ, the terminal determines the RSRQ as the evaluation measurement quantity. Then, the terminal determines the target cell according to the measurement results of the RSRQ evaluation cells 1 and 2. For example, if the terminal determines that the signal quality of the cell1 is higher than that of the cell2 according to the RSRQ result, the terminal determines that the cell1 is the target cell.
3) The network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority in the access trigger condition configuration; the measurement object is a pre-configured cell association measurement object.
In implementation, the network side device may configure an access trigger condition, that is, a trigger condition for performing conditional handover, on the associated measurement object for the preconfigured Cell, or add a trigger condition for performing access to the Secondary Cell Group (SCG), or add a trigger condition for performing access in a change process of the Primary Cell Group (PSCell).
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell3 belonging to measurement objects MO1, MO2, and MO3, respectively, where MO1 and MO2 belong to the same priority, and MO3 is lower in priority than MO1 and MO 2. Then, when the network side device configures the access trigger conditions of the cell1 and the cell2 on the associated measurement objects, i.e. the MO1 and the MO2, the same trigger measurement quantity is configured, taking RSRQ as an example. The triggering measurement quantity of the access triggering condition of the terminal configuration cell3 on the associated measurement object, i.e. MO3, is, for example, RSRP.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures RSRQ results of cell1 and cell2, and RSRP results of cell3, respectively. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, and determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell 2. And the terminal determines that the cell3 does not meet the access triggering condition according to the RSRP result of the cell 3. Since the target cells meeting the access triggering condition are two cells 1 and 2, the terminal needs to determine the target cells from the cells 1 and 2.
Therefore, the terminal determines the triggering measurement quantity of the measurement object associated with the high-priority preconfigured cell in the measurement information configured on the network side as the evaluation measurement quantity. Since the trigger measurement quantities of the access trigger conditions of the cell1 and the cell2 are both RSRQ, the terminal determines the RSRQ as the evaluation measurement quantity. Then, the terminal evaluates RSRQ results of cell1 and cell2 to determine the target cell. For example, if the terminal determines that the RSRQ result of cell1 is higher than the RSRQ result of cell2, the terminal determines that cell1 is the target cell.
4) In the configuration of the access triggering condition, the triggering measurement quantities configured for all the measurement objects belonging to the same priority level comprise the same triggering measurement quantity; the measurement object is a pre-configured cell association measurement object.
In implementation, the network side device may configure an access trigger condition, that is, a trigger condition for performing conditional handover, on the associated measurement object for the preconfigured Cell, or add a trigger condition for performing access to the Secondary Cell Group (SCG), or add a trigger condition for performing access in a change process of the Primary Cell Group (PSCell). And a plurality of access trigger conditions can be configured for one preconfigured cell, a plurality of trigger measurement quantities can be configured for one preconfigured cell. And the UE judges whether the pre-configured cell meets the access triggering condition or not based on the measurement result of the configured triggering measurement quantity.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell3 belonging to measurement objects MO1, MO2, and MO3, respectively, where MO1 and MO2 belong to the same priority, and MO3 is lower in priority than MO1 and MO 2. When the network side device configures the cell1 with the access trigger condition of the MO1, which is the associated measurement object, the configured trigger measurement quantity is SINR. When the cell2 is configured with the access triggering condition of the associated measurement object, i.e. MO2, the configured triggering measurement quantities are SINR and RSRP. The access trigger measurement quantity of the terminal configuration cell3 on the associated measurement object, namely the MO3, is RSRQ.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures the SINR result of cell 1; measuring the SINR and RSRP results of the cell 2; the RSRP result of cell3 is measured. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that the cell1 meets the access triggering condition according to the SINR result of the cell 1; and determining that the cell2 meets the access triggering condition according to the RSRP result of the cell2, and determining that the cell2 meets the access triggering condition according to the SINR result of the cell 2. And determining that the cell3 meets the access triggering condition according to the RSRQ result of the cell 3. Since the target cells meeting the access triggering conditions are cell1, cell2 and cell3, the terminal needs to determine the target cells from cell1, cell2 and cell 3.
Therefore, the terminal determines that, in the measurement information configured on the network side, the high-priority preconfigured cell is in the trigger measurement quantities on the associated measurement object, and the same trigger measurement quantity is the evaluation measurement quantity. Since the cell1 and the cell2 have higher priority than the cell3, the terminal selects a target access cell among the cells of cell1 and cell 2. Since the same trigger measurement amount of the trigger measurement amounts of the cell1 and the cell2 for the access trigger condition on the associated trigger object is SINR, the terminal determines SINR as an evaluation measurement amount. Then, the terminal evaluates the SINR results of cell1 and cell2 and determines the target cell. For example, if the terminal determines that the SINR result of cell1 is higher than the SINR result of cell2, the terminal determines that cell1 is the target cell.
5) The network side equipment configures the same trigger measurement quantity for all the measurement frequency points belonging to the same priority in the access trigger condition configuration; the measurement frequency point is a measurement frequency point associated with a pre-configured cell.
In implementation, the network side device may configure an access trigger condition, that is, a trigger condition for performing conditional handover, on the associated frequency point for the preconfigured cell. Or a trigger condition for executing access in a Secondary Cell Group (SCG) addition process or a Secondary Cell Group master Cell (PSCell) change process. And trigger measurements can be configured for one access trigger condition.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell3, where cell1 is on frequency point freq1, cell2 is on frequency point freq2, and cell3 is on frequency point freq 3. The frequency point freq1 and the frequency point freq2 have the same priority, and the priority of the frequency point freq3 is lower than that of the frequency point freq1 and the frequency point freq 2. When the network side device configures the access trigger conditions of freq1 and freq2, the same trigger measurement quantity is configured, taking RSRQ as an example. The terminal configures the trigger measurement quantity of the access trigger condition of freq3 to be RSRP.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures RSRQ results of cell1 and cell2, and RSRP results of cell3, respectively. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, and determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell 2. And the terminal determines that the cell3 does not meet the access triggering condition according to the RSRP result of the cell 3. Since the target cells meeting the access triggering condition are two cells 1 and 2, the terminal needs to determine the target cells from the cells 1 and 2.
Therefore, the terminal determines that the triggering measurement quantity of the frequency point with high priority in the measurement information configured on the network side is the evaluation measurement quantity. Since the trigger measurement amounts of the access trigger conditions of freq1 and freq are both RSRQ, the terminal determines RSRQ as the evaluation measurement amount. Then, the terminal evaluates RSRQ results of cell1 and cell2 to determine the target cell. For example, if the terminal determines that the RSRQ result of cell1 is higher than the RSRQ result of cell2, the terminal determines that cell1 is the target cell.
6) In the configuration of the access triggering condition, the triggering measurement quantities configured for all the measurement frequency points belonging to the same priority comprise the same triggering measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell.
In implementation, the network side device may configure an access trigger condition, that is, a trigger condition for performing conditional handover, on a frequency point for the pre-configured cell. Or adding a trigger condition for executing access in a Secondary Cell Group (SCG), or adding a trigger condition for executing access in a Primary Cell (PSCell) change process of the Secondary Cell Group. And a plurality of access trigger conditions can be configured for one preconfigured cell, a plurality of trigger measurement quantities can be configured for one preconfigured cell. And the UE judges whether the pre-configured cell meets the access triggering condition or not based on the measurement result of the configured triggering measurement quantity.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell3, where cell1 is on frequency point freq1, cell2 is on frequency point freq2, and cell3 is on frequency point freq 3. Wherein freq1 and freq2 belong to the same priority and freq3 is lower than freq1 and freq 2. When the network side equipment configures the access trigger condition of freq1, the configured trigger measurement quantity is SINR. When the access trigger condition of freq2 is configured, the configured trigger measurement quantities are SINR and RSRP. The terminal configures the trigger measurement quantity of the access trigger condition of freq3 to be RSRQ.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. For example, the terminal measures the SINR result of cell 1; measuring the SINR and RSRP results of the cell 2; the RSRP result of cell3 is measured. And the terminal determines whether each pre-configured cell meets the access triggering condition according to the measurement result. For example, the terminal determines that the cell1 meets the access triggering condition according to the SINR result of the cell 1; and determining that the cell2 meets the access triggering condition according to the RSRP result of the cell2, and determining that the cell2 meets the access triggering condition according to the SINR result of the cell 2. And determining that the cell3 does not meet the access triggering condition according to the RSRQ result of the cell 3. Since the target cells meeting the access triggering conditions are cell1 and cell2, the terminal needs to determine the target cells from cell1 and cell 2.
Therefore, the terminal determines that the same trigger measurement amount is the evaluation measurement amount in the trigger measurement amount of the frequency point with high priority in the measurement information configured on the network side. Since the same triggered measurement quantity among the triggered measurement quantities of the access trigger conditions of freq1 and freq2 is SINR, the terminal determines SINR as an evaluation measurement quantity. Then, the terminal evaluates the SINR results of cell1 and cell2 and determines the target cell. For example, if the terminal determines that the SINR result of cell1 is higher than the SINR result of cell2, the terminal determines that cell1 is the target cell.
7) And configuring the same trigger measurement quantity for the pre-configured cells in the configuration of the access trigger condition.
In implementation, the network side device may allocate a plurality of preconfigured cells to the terminal. And configuring an access triggering condition for each pre-configured cell. And configuring a trigger measurement quantity for one access trigger condition.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, cell3, and cell 4. And the trigger measurement quantity configured for the access trigger condition of each pre-configured cell is RSRQ.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. That is, the RSRQ results of cells 1-4 were measured, respectively. And respectively determining whether the cells 1-4 meet respective access triggering conditions according to the RSRQ result. The terminal determines that the cell1 and the cell2 do not meet respective access triggering conditions according to the RSRQ results of the cell1 and the cell2, and determines that the cell3 and the cell4 meet respective access triggering conditions according to the RSRQ results of the cell3 and the cell 4. Therefore, the terminal needs to determine the target cell from cell3 and cell 4.
Since the trigger measurement quantities of the access trigger conditions of the cells 1-4 are all RSRQ, the terminal determines the RSRQ as the evaluation measurement quantity. And the terminal determines that the RSRQ result of the cell3 is higher than that of the cell4, and determines that the target cell is the cell 3.
8) And in the configuration of the access triggering condition, the triggering measurement quantities configured for the pre-configured cells comprise the same triggering measurement quantity.
In implementation, the network side device may allocate a plurality of preconfigured cells to the terminal. And configuring an access triggering condition for each pre-configured cell. And a plurality of access trigger conditions can be configured for one preconfigured cell, a plurality of trigger measurement quantities can be configured for one preconfigured cell.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell 3. The trigger measurement quantity configured for the cell1 is RSRQ, the trigger measurement quantity configured for the cell2 is RSRQ and SINR, and the trigger measurement quantity configured for the cell3 is RSRQ and RSRP.
And the terminal measures each pre-configured cell according to the triggering measurement quantity of the access triggering condition of each pre-configured cell in the measurement information. That is, the terminal measures the RSRQ result of cell1, the RSRQ and SINR result of cell2, and the RSRQ and RSRP result of cell 3. The terminal determines that the cell1 does not meet the access triggering condition according to the RSRQ result of the cell1, determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell2, and determines that the cell2 meets the access triggering condition according to the SINR result of the cell 2; and the terminal determines that the cell3 meets the access triggering condition according to the RSRQ result of the cell3, and determines that the cell3 meets the access triggering condition according to the RSRP result of the cell 3. Since both cell2 and cell3 satisfy the access triggering condition, respectively, the terminal needs to determine the target cell from cell2 and cell 3.
Since the same trigger measurement amount RSRQ exists in the trigger measurement amounts of cell2 and cell3, the terminal determines the RSRQ as the evaluation measurement amount. And the terminal determines that the RSRQ result of the cell2 is higher than the RSRQ result of ell3, and determines that the cell2 is the target cell.
Mode 2: the measurement information includes an evaluation measurement quantity.
The network side equipment configures the pre-configured cells and the triggering measurement quantity of the access triggering conditions of each pre-configured cell for the terminal. The network device configures the specified measurement quantity type as an evaluation measurement quantity to the UE. The network configuration may send the evaluation measurements to the UE through system information or dedicated signaling.
For example, the preconfigured cells configured for the terminal by the network side device include cell1, cell2, and cell 3. And the trigger measurement quantity configured for the access trigger condition of the cell1 is RSRQ, the trigger measurement quantity configured for the access trigger condition of the cell2 is RSRP, and the trigger measurement quantity configured for the access trigger condition of the cell3 is SINR.
The terminal measures the RSRQ result of cell1, the RSRP result of cell2, and the SINR result of cell 3. And the network side equipment sends the specified measurement quantity type as the evaluation measurement quantity between the cells to the terminal. The terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell 1; determining that the cell2 meets the access triggering condition according to the RSRP result of the cell 2; and determining that the cell3 meets the access triggering condition according to the SINR of the cell3 result, so that the terminal needs to determine the target cell from the cell1, the cell2 and the cell 3.
The terminal determines the specified measurement quantity type as an evaluation measurement quantity. For example, if the specified measurement quantity type is RSRQ, the terminal determines that the evaluation measurement quantity is RSRQ. And the terminal determines that the RSRQ result of the cell1 is higher than the RSRQ results of the cell2 and the cell3, and determines that the cell1 is the target cell.
In practice, the terminal may calculate the RSRQ of cell2 and the RSRQ of cell 3.
Mode 3: the measurement information includes a priority for evaluating the measurement quantity.
The preconfigured cell allocated by the network side equipment for the terminal comprises a cell1 and a cell2, and the triggering measurement quantity of the access triggering condition of the cell1 is configured to be RSRQ and RSRP, and the triggering measurement quantity of the access triggering condition of the cell2 is configured to be RSRQ and RSRP.
The terminal measures the RSRQ and RSRP results of cell1 and measures the RSRQ and RSRP results of cell 2. And the terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, and determines that the cell1 meets the access triggering condition according to the RSRP result of the cell 1. And the terminal determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell2, and determines that the cell2 meets the access triggering condition according to the RSRP result of the cell 2. Therefore, the terminal needs to determine the target cell in cell1 and cell 2.
The network side equipment determines that the measurement information of the terminal comprises the priority of the estimated measurement quantity, for example, the priority of RSRP is higher than that of RSRQ, and the priority of RSRQ is higher than that of SINR. Therefore, the terminal determines the evaluation measurement quantity to be RSRP according to the measurement information. And the terminal determines that the RSRP result of the cell1 is higher than that of the cell2, and determines that the cell1 is the target cell.
The second method comprises the following steps: the terminal determines the estimated measurement quantity according to the measurement information
Referring to fig. 3, a flowchart of a method for determining a target cell in an embodiment of the present application may include the following steps:
step 301: and the network side equipment configures the measurement information of the terminal.
Step 302: and the terminal determines the estimated measurement quantity according to the measurement information sent by the network side equipment.
Step 303: and the terminal evaluates the pre-configured cells meeting the access triggering conditions according to the measurement results of the evaluation measurement quantity.
Step 304: and the terminal selects a target cell according to the evaluation result.
In practice, the measurement information may include some or all of the following: triggering measurement quantity, evaluation measurement quantity and priority of the evaluation measurement quantity of the access triggering condition of each pre-configured cell. The following is a detailed description based on the above.
Mode 1: the measurement information comprises trigger measurement quantities of access trigger conditions of each pre-configured cell
1) And the terminal takes the trigger measurement quantity contained in the access trigger condition of the pre-configured cell meeting the access trigger condition as the evaluation measurement quantity.
In implementation, the network side device configures the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell for the terminal. The network side equipment configures the same trigger measurement quantity for all the preconfigured cells belonging to the same priority, or the network side equipment configures the trigger measurement quantity for all the preconfigured cells belonging to the same priority, wherein the trigger measurement quantity comprises the same trigger measurement quantity, or the network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority; the measurement object is a measurement object associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all measurement objects belonging to the same priority level comprise the same trigger measurement quantity; the measurement object is a measurement object associated with a pre-configured cell, or the network side equipment configures the same trigger measurement quantity for all measurement frequency points belonging to the same priority; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all the measurement frequency points belonging to the same priority level comprise the same trigger measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the network side device configures the same trigger measurement quantity for all pre-configured cells, or the network side device configures the trigger measurement quantity for all pre-configured cells including the same trigger measurement quantity. Or the network side does not make any limitation and arbitrarily configures the trigger measurement quantity of the access trigger condition for each pre-configured cell.
For example, the preconfigured cell configured for the terminal by the network side device includes cell1, cell2, and cell3, the trigger measurement quantity configured for the access trigger condition of cell1 is RSRQ, the trigger measurement quantity configured for the access trigger condition of cell2 is RSRP and RSRQ, and the trigger measurement quantity configured for the access trigger condition of cell3 is RSRQ.
The terminal measures the RSRQ result of cell1, the RSRP result of cell2 and the RSRQ result of cell2, and the RSRQ result of cell 3. The terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, determines that the cell2 meets the access triggering condition according to the RSRP result of the cell2, determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell2, and determines that the cell3 meets the access triggering condition according to the RSRQ result of the cell 3. The terminal needs to determine the target cell in cell1, cell2, and cell 3.
Since the access trigger conditions of the pre-configured cells 1-3 satisfying the access trigger conditions each include RSRQ as a trigger measurement quantity, the terminal determines the RSRQ as an evaluation measurement quantity. And the terminal determines that the RSRQ result of the cell1 is higher than the RSRQ result of the cell2 and the RSRQ result of the cell3, and the terminal determines that the cell1 is the target cell.
2) And the terminal takes the trigger measurement quantity contained in the access trigger condition of the high-priority pre-configured cell meeting the access trigger condition as the evaluation measurement quantity.
In implementation, the network side device allocates the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell to the terminal. The network side equipment configures the same trigger measurement quantity for all the preconfigured cells belonging to the same priority, or the network side equipment configures the trigger measurement quantity for all the preconfigured cells belonging to the same priority, wherein the trigger measurement quantity comprises the same trigger measurement quantity, or the network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority; the measurement object is a measurement object associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all measurement objects belonging to the same priority level comprise the same trigger measurement quantity; the measurement object is a measurement object associated with a pre-configured cell, or the network side equipment configures the same trigger measurement quantity for all measurement frequency points belonging to the same priority; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all the measurement frequency points belonging to the same priority level comprise the same trigger measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell. Or the network side does not make any limitation and arbitrarily configures the trigger measurement quantity of the access trigger condition for each pre-configured cell.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell 3. The frequency point of cell1 is freq1, the frequency point of cell2 is freq2, and the frequency point of cell3 is freq 3. Wherein freq1 and freq2 are of the same priority and higher than freq 3. The network side device configures the RSRQ as the trigger measurement quantity configured for the access trigger condition of freq1, the RSRP and the RSRQ as the trigger measurement quantity configured for the access trigger condition of freq2, and the SINR as the trigger measurement quantity configured for the access trigger condition of freq 3.
The terminal measures the RSRQ result of cell1, the RSRP result of cell2 and the RSRQ result of cell2, and the SINR result of cell 3. The terminal determines that the cell1 meets the access triggering condition according to the RSRQ result of the cell1, determines that the cell2 meets the access triggering condition according to the RSRP result of the cell2, determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell2, and determines that the cell3 meets the access triggering condition according to the SINR result of the cell 3. The terminal needs to determine the target cell in cell1, cell2, and cell 3.
Since the access triggering conditions are met in the pre-configured cells, freq1 and freq2 are higher priority than freq 3. Therefore, the terminal needs to determine an evaluation measurement amount among the trigger measurement amounts of the access trigger conditions of the cell1 and the cell 2. The trigger measurement quantity of freq1 is RSRQ, the trigger measurement quantities of freq2 are RSRP and RSRQ, and since RSRQ exists in both the trigger measurement quantities of freq1 and freq2, the terminal determines RSRQ as the evaluation measurement quantity. Since freq1 and freq2 are higher priority than freq3, the UE excludes cell3 and selects the target cell in cell1 and cell 2.
And the terminal determines that the RSRQ result of the cell1 is higher than that of the cell2, and the terminal determines that the cell1 is the target cell.
3) And the terminal takes the triggering measurement quantity with the maximum quantity in the access triggering conditions of the pre-configured cells meeting the access triggering conditions as the evaluation measurement quantity.
In implementation, the network side device allocates the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell to the terminal. The network side equipment configures the same trigger measurement quantity for all the preconfigured cells belonging to the same priority, or the network side equipment configures the trigger measurement quantity for all the preconfigured cells belonging to the same priority, wherein the trigger measurement quantity comprises the same trigger measurement quantity, or the network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority; the measurement object is a measurement object associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all measurement objects belonging to the same priority level comprise the same trigger measurement quantity; the measurement object is a measurement object associated with a pre-configured cell, or the network side equipment configures the same trigger measurement quantity for all measurement frequency points belonging to the same priority; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all the measurement frequency points belonging to the same priority level comprise the same trigger measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the network side device configures the same trigger measurement quantity for all pre-configured cells, or the network side device configures the trigger measurement quantity for all pre-configured cells including the same trigger measurement quantity. Or the network side does not make any limitation and arbitrarily configures the trigger measurement quantity of the access trigger condition for each pre-configured cell.
For example, the preconfigured cell allocated by the network side device to the terminal includes cell1, cell2, and cell3, the trigger measurement quantity configured for the access trigger condition of cell1 is RSRQ, the trigger measurement quantity configured for the access trigger condition of cell2 is RSRP and SINR, and the trigger measurement quantity configured for the access trigger condition of cell3 is RSRQ.

The terminal needs to determine the target cell in cell1, cell2, and cell 3.
The terminal determines the RSRQ as an evaluation measurement quantity because the most triggering measurement quantities contained in the access triggering conditions of the preconfigured cells 1-cell3 that satisfy the access triggering conditions are RSRQ, RSRQ is configured as a triggering measurement quantity in the access triggering conditions of two cells, respectively, and RSRP and SINR are configured as triggering measurement quantities in the access triggering conditions of only one cell, respectively. And the terminal determines that the RSRQ result of the cell1 is higher than the RSRQ result of the cell2 and the RSRQ result of the cell3, and the terminal determines that the cell1 is the target cell.
4) And the terminal determines the estimated measurement quantity according to the preset measurement quantity type.

And the terminal determines the estimated measurement quantity to be RSRP according to the preset measurement quantity type RSRP. And the terminal determines that the RSRP result of the cell1 is higher than the RSRP results of the cell2 and the cell3, and the terminal determines that the cell1 is the target cell.

For example, the protocol specifies RSRP as an estimated measurement quantity between preconfigured cells satisfying the access triggering condition, or a measurement quantity specified by the network via signaling or system information configuration to the UE as an estimated measurement quantity between preconfigured cells satisfying the access triggering condition.
Mode 2: the measurement information comprises a priority for triggering and/or evaluating the measurement quantity
1) And the terminal takes the measurement quantity with higher priority in the trigger measurement quantities contained in the access trigger conditions of the pre-configured cells meeting the access trigger conditions as the evaluation measurement quantity, wherein the priority of the measurement quantity is the preset priority specified by a protocol or the priority of the evaluation measurement quantity configured by the network.
In implementation, the network side device allocates the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell to the terminal. The network side equipment configures the same trigger measurement quantity for all the preconfigured cells belonging to the same priority, or the network side equipment configures the trigger measurement quantity for all the preconfigured cells belonging to the same priority, wherein the trigger measurement quantity comprises the same trigger measurement quantity, or the network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority; the measurement object is a measurement object associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all measurement objects belonging to the same priority level comprise the same trigger measurement quantity; the measurement object is a measurement object associated with a pre-configured cell, or the network side equipment configures the same trigger measurement quantity for all measurement frequency points belonging to the same priority; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all the measurement frequency points belonging to the same priority level comprise the same trigger measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the network side device configures the same trigger measurement quantity for all pre-configured cells, or the network side device configures the trigger measurement quantity for all pre-configured cells including the same trigger measurement quantity. Or the network side does not make any limitation and arbitrarily configures the trigger measurement quantity of the access trigger condition for each pre-configured cell.
For example, the preconfigured cell allocated by the network side device to the terminal includes cell1, cell2, and cell3, the trigger measurement quantities configured for the access trigger condition of cell1 are RSRP and RSRQ, the trigger measurement quantities configured for the access trigger condition of cell2 are RSRP and RSRQ, and the trigger measurement quantities configured for the access trigger condition of cell3 are RSRQ.

The terminal needs to determine the target cell in cell1 and cell 2.
Since the access trigger conditions of the pre-configured cells 1 and 2 satisfying the access trigger conditions each include RSRQ and RSRP, the terminal determines an evaluation measurement quantity from the RSRQ and RSRP. For example, the RSRQ has a higher priority than the RSRP, and the terminal determines the RSRQ result as an evaluation measurement quantity. And the terminal determines that the RSRQ of the cell1 is higher than the RSRQ result of the cell2, and the terminal determines that the cell1 is the target cell.
In implementation, the priority of the measurement volume may be a priority specified by a protocol or may also be a priority of evaluating the measurement volume configured by the network side device.
For example, the network side device may configure a trigger measurement quantity of the access trigger condition for each preconfigured cell, and configure a priority for evaluating the measurement quantity for the terminal, where the priority of RSRQ is higher than that of RSRP, and the priority of RSRP is higher than that of SINR.
As another example, a protocol may specify a priority for evaluating the measurement quantity. For example, RSRP may be set to have a higher priority than RSRQ and RSRQ may have a higher priority than SINR.
2) And the terminal takes the measurement quantity with the higher priority in the trigger measurement quantities contained in the access trigger conditions of the pre-configured cell with the high priority meeting the access trigger conditions as the evaluation measurement quantity, wherein the priority of the measurement quantity is the preset priority or the priority of the evaluation measurement quantity configured by the network.
In implementation, the network side device allocates the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell to the terminal. The network side equipment configures the same trigger measurement quantity for all the preconfigured cells belonging to the same priority, or the network side equipment configures the trigger measurement quantity for all the preconfigured cells belonging to the same priority, wherein the trigger measurement quantity comprises the same trigger measurement quantity, or the network side equipment configures the same trigger measurement quantity for all the measurement objects belonging to the same priority; the measurement object is a measurement object associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all measurement objects belonging to the same priority level comprise the same trigger measurement quantity; the measurement object is a measurement object associated with a pre-configured cell, or the network side equipment configures the same trigger measurement quantity for all measurement frequency points belonging to the same priority; the measurement frequency point is a measurement frequency point associated with a pre-configured cell, or the trigger measurement quantities configured by the network side equipment for all the measurement frequency points belonging to the same priority level comprise the same trigger measurement quantity; the measurement frequency point is a measurement frequency point associated with a pre-configured cell. Or the network side does not make any limitation and arbitrarily configures the trigger measurement quantity of the access trigger condition for each pre-configured cell.
For example, the preconfigured cells allocated by the network side device for the terminal include cell1, cell2, and cell 3. Also, the priority of cell1 is equal to the priority of cell2, and the priority of cell2 is higher than the priority of cell 3. The network side device configures the access trigger condition of the cell1 with the trigger measurement quantity of RSRQ and RSRP, configures the access trigger condition of the cell2 with the trigger measurement quantity of RSRP, and configures the access trigger condition of the cell3 with the trigger measurement quantity of SINR.

The terminal needs to determine the target cell in cell1, cell2, and cell 3.
Since the priorities of cell1 and cell2 are higher than the priority of cell3 in the preconfigured cells satisfying the access triggering conditions, and since the priority of cell3 is lower, the UE excludes cell3, the terminal determines the evaluation measurement quantity in the triggered measurement quantities RSRQ and RSRP of the access triggering conditions of cell1 and cell 2. For example, the RSRP has a higher priority than the RSRQ, and the terminal determines the RSRP as the evaluation measurement quantity. And the terminal determines that the RSRP result of the cell1 is higher than that of the cell2, and the terminal determines that the cell1 is the target cell.
In implementation, the priority of the measurement volume may be a preset priority specified by a protocol or may also be a priority of an evaluation measurement volume configured by a network side device.
For example, the network side device may configure a trigger measurement quantity of the access trigger condition for each preconfigured cell, and configure a priority for evaluating the measurement quantity for the terminal, where the priority of RSRQ is higher than that of RSRP, and the priority of RSRP is higher than that of SINR.
As another example, a protocol may specify a priority for evaluating the measurement quantity. For example, RSRP may be set to have a higher priority than RSRQ and RSRQ may have a higher priority than SINR.
3) And the terminal takes the measurement quantity with the higher priority in the triggering measurement quantities with the maximum quantity contained in the access triggering conditions of the pre-configured cells meeting the access triggering conditions as the evaluation measurement quantity, wherein the priority of the measurement quantity is the preset priority or the priority of the evaluation measurement quantity configured by the network.
In implementation, the network side device allocates the preconfigured cells and the trigger measurement quantity of the access trigger condition of each preconfigured cell to the terminal.
For example, the preconfigured cell allocated by the network side device to the terminal includes cell1, cell2, and cell3, the trigger measurement quantities configured for the access trigger condition of cell1 are RSRP and RSRQ, the trigger measurement quantities configured for the access trigger condition of cell2 are RSRP and RSRQ, and the trigger measurement quantity configured for the access trigger condition of cell3 is SINR.

The terminal needs to determine the target cell in cell1, cell2, and cell 3.
Since the most numerous trigger measurement quantities included in the access trigger conditions of the preconfigured cells cell1, cell2, and cell3 satisfying the access trigger conditions are RSRP and RSRQ, the terminal needs to determine an evaluation measurement quantity among the RSRP and RSRQ. For example, the RSRQ has a higher priority than the RSRP, the terminal determines the RSRQ as the evaluation measurement quantity. And the terminal determines that the RSRQ result of the cell1 is higher than the RSRQ results of the cell2 and the cell3, and the terminal determines that the cell1 is the target cell.
In implementation, the priority of the measurement volume may be a preset priority specified by a protocol or may also be a priority of an evaluation measurement volume configured by a network side device.
For example, the network side device may configure a trigger measurement quantity of the access trigger condition for each preconfigured cell, and configure a priority for evaluating the measurement quantity for the terminal, where the priority of RSRQ is higher than that of RSRP, and the priority of RSRP is higher than that of SINR.
As another example, a protocol may specify a priority for evaluating the measurement quantity. For example, RSRP may be set to have a higher priority than RSRQ and RSRQ may have a higher priority than SINR.

And the terminal measures the RSRP result of the cell1, the RSRQ result of the cell2 and the SINR result of the cell 3. The terminal determines that the cell1 meets the access triggering condition according to the RSRP result of the cell1, and determines that the cell2 meets the access triggering condition according to the RSRQ result of the cell 2. The terminal determines that the cell3 result does not satisfy the access triggering condition. The terminal needs to determine the target cell from cell1 and cell 2.
The terminal takes RSRP as an example, as an evaluation measurement according to the measurement type specified by the network side device. The type of the measurement quantity designated by the network side equipment is RSRP, and the terminal determines the evaluation measurement quantity to be RSRP. And the terminal determines that the RSRP result of the cell1 is higher than that of the cell2, and determines that the cell1 is the target cell.

In practice, step 3 may also be performed as: the three cells of cell1, cell2, and cell3 simultaneously satisfy the handover execution condition, since RSRP exists in cell1 and cell2 as the trigger measurement quantity, RSRQ exists in cell2 and cell3 as the trigger measurement quantity, the number of cells satisfying the CHO execution trigger handover condition and configured with RSRP as the trigger measurement quantity is 2, the number of cells satisfying the CHO execution trigger handover condition and configured with RSRQ as the trigger measurement quantity is 2, the UE determines the evaluation measurement quantity according to a specified priority criterion, for example, the priority is RSRP > RSRQ > SINR, and the UE evaluates and compares cell1, cell2, and cell3 according to the RSRP result. For example, cell1 has a signal quality higher than cell2 and cell3, the UE selects cell1 for access. The preset priority can be protocol specification or network configuration through signaling.
Example 8: UE selects a common trigger measurement quantity of pre-configured cells satisfying a CHO execution trigger condition as evaluation Measured quantity
Step 1: the network configures preconfigured cells cell1, cell2 and cell3 for the UE. When the network side configures the CHO execution trigger conditions for the cell1 and the cell2, the same trigger measurement quantity is configured, taking RSRP as an example, and additionally, RSRQ is configured for the cell2 as the trigger measurement quantity. Configuring the cell3 with the CHO execution trigger condition configures the RSRQ as the trigger measurement quantity.
Step 2: the UE determines whether the cell1 and the cell2 meet the CHO execution triggering condition according to the RSRP measurement results of the cell1 and the cell2, determines whether the cell2 meets the CHO execution triggering condition according to the RSRQ measurement result of the cell2, and determines whether the cell3 meets the CHO execution triggering condition according to the RSRQ measurement result of the cell 3.
And step 3: the two cells of cell1 and cell2 simultaneously satisfy respective CHO execution triggering conditions, since RSRP exists in the CHO execution triggering conditions of cell1 and cell2 at the same time as a triggering measurement quantity, the UE uses the triggering measurement quantity RSRP common to the two cells as an evaluation measurement quantity, the UE compares and selects according to the RSRP measurement results of the two cells, for example, the signal quality of cell1 is higher than that of cell2, and the UE selects cell1 for access.
In practice, step 3 may also be performed as: the two cells of cell2 and cell3 simultaneously satisfy respective CHO execution triggering conditions, since RSRQ exists in cell2 and cell3 simultaneously as triggering measurement quantities, the UE uses the triggering measurement quantity RSRQ shared by the two cells as an evaluation measurement quantity, and the UE compares and selects according to the RSRQ measurement results of the two cells, for example, if the signal quality of cell3 is higher than that of cell2, the UE selects cell3 for access.
In practice, step 3 may also be performed as: two cells, cell1 and cell3, satisfy the handover execution condition at the same time, and since the same trigger measurement amount does not exist in cell1 and cell3, the UE determines the evaluation measurement amount in the manner of embodiment 5 or embodiment 6 or embodiment 7, and performs evaluation comparison on cell1 and cell 3.
In practice, step 3 may also be performed as: the network side adds a preconfigured cell4 to the UE, the cell4 configures a CHO execution triggering condition taking RSRP and RSRQ as triggering measurement quantities, and the UE judges whether the cell4 meets the CHO execution triggering condition according to the RSRP and RSRQ results of the cell 4.
Step 4 may also be performed as: the two cells of cell2 and cell4 simultaneously satisfy the handover execution condition, since the same triggered measurement quantities RSRP and RSRQ exist in cell4 and cell2, the UE determines the evaluation measurement quantities according to the preset priority, for example, the priority is RSRP > RSRQ > SINR, and the UE evaluates and compares cell2 and cell4 according to the RSRP measurement results. For example, the signal quality of cell2 is higher than that of cell4, the UE selects cell2 for access. The preset priority can be protocol specification or network configuration through signaling.
