Detailed ways

In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

Figure 1 is a schematic diagram of an application scenario of a conditional handover method provided by an embodiment of the application. As shown in Figure 1, the scenario includes a user terminal, a source cell base station (Source eNB), and a target cell base station (Target eNB). A cell moves to another cell, or, due to wireless transmission traffic load adjustment, activation operation maintenance, equipment failure, etc., in order to ensure communication continuity and service quality, the communication link between the user and the source cell base station is transferred To the base station of the target cell, the handover process is executed.

At present, the current 3GPP discussions have reached the following conclusions regarding the handover conditions: 1. The measurement report is not triggered for the cell that triggers the conditional handover; 2. The conditions that trigger the conditional handover can be configured using the conditions that trigger the measurement report.

Considering the above conclusion 2, the measurement ID (Measurement ID) used for measurement reporting can be used to configure the conditions for condition switching. However, the traditional measurement ID is used to trigger measurement reporting. Then, the condition switching method provided in this application can solve How to use the condition that triggers the measurement report to configure the condition of the trigger condition switch. However, the present application is not limited to solving the technical problem of “how to use the condition of triggering measurement report to configure the condition of triggering condition switching”, and can also be used to solve other technical problems.

Furthermore, how to ensure that the measurement identifier does not trigger the measurement report for the cell that triggers the conditional handover, that is, to prevent the UE from triggering the corresponding measurement report, there are three situations that need to be distinguished:

1) The measurement identifier is used to trigger measurement reporting, not to trigger condition switching, that is, the role of the traditional measurement identifier;

2) The measurement identifier is used to trigger condition switching, not to trigger measurement reporting, indicating that the measurement identifier is only used for condition switching;

3) The measurement identifier is used to trigger measurement reporting and condition switching. The situation where both are used may be, for example, for the target neighboring cell, the measurement identifier is used to trigger condition switching, while for other neighbors In the cell, the measurement identifier is used to trigger measurement reporting.

The following describes in detail the condition switching method provided by the embodiment of the present application for the above three situations.

Fig. 2 is a flowchart of a condition switching method provided by an embodiment of the application, and the execution subject of the method is a user terminal. As shown in Figure 2, the method includes:

S201. The user equipment receives a configuration message sent by the access network device; the configuration message includes measurement report configuration and condition switching configuration; the measurement report configuration and/or condition switching configuration includes a measurement identifier, and the measurement identifier is used to indicate whether to trigger a measurement report.

Among them, the measurement report configuration is used to configure the conditions of the measurement report, such as the measurement object and the measurement report trigger mode. The conditional switching configuration is used to configure the conditions for conditional switching, and the cell switching can be directly performed when the UE conditionally switches. To meet the requirements, the following takes the Radio Resource Management (RRM) measurement report configuration as an example to describe the measurement report configuration in detail.

For example, the UE performs measurement according to the measurement report configuration issued by the access network equipment, and evaluates the measurement report when a certain trigger condition is met. If the report condition is met, the UE will fill in the measurement report and include it in the measurement report and send it to Access network equipment. Measurement reports are divided into three categories:

1) Event triggering: The UE triggers the sending of the measurement report only after the measurement event entry threshold configured by the network is met and continues for a period of time, and the process ends after the measurement report is sent once. The reporting configuration corresponding to this criterion is:

The trigger type is "event", including A1-A6, B1-B2, one of the measurement events and their threshold parameters;

The number of reports is 1;

Regardless of the value of the reporting interval, the UE ignores it.

2) Periodic reporting: After the network configuration measurement is reported, the UE measures the corresponding frequency points according to the configuration content, and sends the measurement report according to the specified reporting period and interval.

The trigger cycle includes the reporting purpose "reportCGI" and "reportStrongestCell";

If the report purpose is "reportCGI", the number of reports is equal to 1, and if the report purpose is "reportStrongestCell", the number of reports can be greater than 1.

Once the UE is configured with the "reportCGI" report purpose, the T321 timer will be started. In order for the network to obtain the necessary information for forming the neighbor cell list as soon as possible, the UE can stop T321 if the content required for reporting has been obtained before the T321 timer expires And initiate a report in advance.

3) Event trigger periodic reporting: The UE will trigger the sending of measurement reports only when the measurement trigger event entry threshold configured by the network is met and lasts for a period of time. After the reporting is triggered, the timer between multiple measurements and A counter of the number of measurements, and the process ends when the number of reports reaches the requirements. The reporting configuration corresponding to this criterion is:

The trigger type is "event", including a measurement event from A1 to A5 and its threshold parameters;

The number of reports is greater than 1;

The reporting interval is valid, and the network sets the reporting cycle timer according to the configured interval parameter.

In this embodiment, the user equipment can receive the configuration message sent by the access network device. The configuration message includes the measurement report configuration and the condition switching configuration, and the condition switching configuration reuses the measurement identifier in the measurement report configuration, and the measurement identifier is redefined , It will not trigger measurement report under some preset conditions. For example, the measurement identifier can be defined in the measurement report configuration. When the attribute value of the measurement identifier is TRUE, the measurement identifier does not trigger measurement report. If the measurement identifier is included in the condition switching configuration at the same time, the measurement identifier Also use trigger conditions to switch. Alternatively, the measurement identifier is defined in the condition switching configuration to trigger condition switching, and the attribute value of the measurement identifier is FALSE, then the measurement identifier does not trigger measurement reporting. Or, the protocol pre-prescribes that the measurement identifier is used to trigger condition switching and is not used to trigger measurement reporting, no matter if the measurement identifier is defined in the measurement reporting configuration or the condition switching configuration, the measurement reporting will not be triggered. Alternatively, the measurement identifier can be set to trigger measurement reporting for cells in the whitelisted cell list, and not to trigger measurement reporting for cells other than the measurement identifier, and so on. Different preset conditions can be set according to actual conditions, so that the measurement identifier does not trigger measurement reporting in some scenarios.

In the condition switching method provided in this embodiment, the user equipment receives the configuration message sent by the access network device. The configuration message includes the measurement report configuration and the condition switching configuration. Because the measurement report configuration and/or the condition switching configuration includes the measurement identifier, the measurement identifier uses To indicate whether to trigger the measurement report, so that when the measurement flag in the trigger measurement report is reused to trigger condition switching in some scenarios, the corresponding measurement report will not be triggered.

FIG. 3 is a flowchart of a conditional handover method provided by an embodiment of the application, and the execution subject of the method is an access network device, for example, a cell base station. As shown in Figure 3, the method includes:

S301. The access network device sends a configuration message to the user equipment; the configuration message includes measurement report configuration and condition switching configuration; the measurement report configuration and/or condition switching configuration includes a measurement identifier, and the measurement identifier is used to indicate whether to trigger a measurement report.

Among them, the measurement report configuration is used to configure the conditions of the measurement report, such as the measurement object and the measurement report trigger mode. The conditional handover configuration is used to configure the conditions for conditional handover. When the UE conditional handover conditions are met, cell handover can be performed directly. The following takes Radio Resource Management (RRM) measurement report configuration as an example to describe the measurement report configuration in detail.

In the Long Term Evolution (LTE) system, the access network device sends the measurement report configuration to the connected UE. The UE performs measurement (same frequency, different frequency, different technology) according to the content of the measurement report configuration, and then measures The result is reported to the access network device. The access network equipment uses connection reconfiguration for measurement configuration. The measurement report configuration includes the following:

1) Measurement Object: Taking frequency as the basic unit, each configured measurement object is a separate frequency point and has a separate measurement object identifier (ID). For the evolved universal wireless access (Evolved Universal Terrestrial Radio Access, E-UTRA) Same-frequency and inter-frequency measurement. The measurement object is a single E-UTRA carrier frequency. For cells related to the carrier frequency, E-UTRA may configure a whitelist cell list and a blacklist cell list.

a) For the white list cell list, the LTE system determines whether to measure and report only the cells in the white list cell list in conjunction with the white list cell list (use White Cell List) in the measurement report configuration.

b) The UE does not perform any operation on the blacklisted cells in the measurement evaluation and measurement report.

2) Measurement report method: According to the type, it is divided into event trigger report and periodic trigger report. Each method has a separate identification (ID). The event trigger report includes the event type and threshold value, and the duration of meeting the trigger condition (Time to Trigger). The periodic trigger report includes the report period and the purpose of the periodic trigger. At present, the same frequency/different frequency measurement events in the LTE system include the following:

-Event A1: Serving becomes better than absolute threshold;

-Event A2: Serving becomes Worse than absolute threshold;

-Event A3: Neighbour becomes amount of offset better than PCell/PSCell;

-Event A4: Neighbour becomes better than absolute threshold;

-Event A5: PCell/PSCell becomes worst than absolute threshold1 AND Neighbour/SCell becomes better than another absolute threshold 2.

-Event A6: Neighbour becomes amount of offset better than SCell.

-Event B1: Neighbour becomes better than absolute threshold;

-Event B2: PCell becomes worst than absolute threshold1 AND Neighbour becomes better than another absolute threshold2.

3) Measurement ID (Measurement ID): The measurement ID associates a measurement object with a specific measurement reporting method, that is, each measurement ID corresponds to a predetermined measurement object and measurement reporting method. If the UE reaches the measurement start threshold, the UE will determine whether to perform this type of measurement according to the presence of the measurement identifier.

4) Other parameters: including measurement gap, measurement opening threshold and speed status parameters.

In this embodiment, the access network device may send a configuration message to the user equipment in advance. The configuration message includes measurement report configuration and conditional switching configuration, and the conditional switching configuration reuses the measurement identifier in the measurement report configuration, and the measurement identifier is redefined , It will not trigger measurement report under some preset conditions. For example, the measurement identifier can be defined in the measurement report configuration. When the attribute value of the measurement identifier is TRUE, the measurement identifier does not trigger measurement report. If the measurement identifier is included in the condition switching configuration at the same time, the measurement identifier Also use trigger conditions to switch. Alternatively, the measurement identifier is defined in the condition switching configuration to trigger condition switching, and the attribute value of the measurement identifier is FALSE, then the measurement identifier does not trigger measurement reporting. Or, the protocol pre-prescribes that the measurement identifier is used to trigger condition switching and is not used to trigger measurement reporting, no matter if the measurement identifier is defined in the measurement reporting configuration or the condition switching configuration, the measurement reporting will not be triggered. Alternatively, the measurement identifier can be set to trigger measurement reporting for the cells in the whitelisted cell list, and not to trigger measurement reporting for cells other than the measurement identifier, and so on. Different preset conditions can be set according to actual conditions, so that the measurement identifier does not trigger measurement reporting in some scenarios.

Optionally, the configuration message is carried in radio resource control (Radio Resource Control, RRC) signaling. The configuration message is directly carried in the RRC signaling without sending the configuration message separately, which can reduce the signaling overhead.

In the condition switching method provided in this embodiment, the access network device sends a configuration message to the user equipment. The configuration message includes the measurement report configuration and the condition switching configuration. Since the measurement report configuration and/or the condition switching configuration includes the measurement identifier, the measurement identifier is used for Indicate whether to trigger the measurement report, so that when the measurement flag in the trigger measurement report is reused to trigger condition switching, the corresponding measurement report will not be triggered.

In the following, on the basis of the embodiments shown in FIG. 2 and FIG. 3, various possible implementations of the condition switching method are described in detail in four scenario embodiments.

Example 1: Conditional switching configuration reuses the measurement identifier definition in the measurement report configuration to configure the attribute value for the measurement identifier to define whether the measurement identifier triggers the measurement report through different attribute values, which can be specifically divided into two methods: method one and method two Program.

Manner 1: The measurement report configuration includes the measurement identifier and the attribute value of the measurement identifier. The attribute value is used to indicate whether to trigger the measurement report.

In this embodiment, the measurement identifier and its attribute value are defined in the measurement report configuration, and different attribute values are set to define whether the measurement identifier triggers the measurement report. Optionally, if the attribute value is the first value, the measurement identifier does not trigger the measurement report; if the attribute value is not the first value, the measurement identifier is used to trigger the measurement report. For example, if the first value is TRUE, if the measurement identifier is configured in the measurement report configuration and the attribute value is TRUE, the measurement identifier does not trigger the measurement report; if the attribute value is FALSE, the measurement identifier triggers the measurement report. Or, if the attribute value is the first value, the measurement flag triggers measurement report; if the attribute value is not the first value, the measurement flag is not used to trigger measurement report; or, the first value can also be FALSE, 0, or 1, etc. Other parameters are not limited in this embodiment.

Further, the condition switching configuration includes a measurement identifier, and the measurement identifier is used to trigger the condition switching. If the measurement identifier is configured in the measurement report configuration, it can also be determined whether the measurement identifier is used to trigger condition switching according to whether the measurement identifier is included in the condition switching configuration. For example, if the measurement identifier is configured in the measurement report configuration and the measurement identifier is also included in the condition switching configuration, the measurement identifier is also used to trigger the condition switching.

Optionally, the attribute value is a part of the measurement identification; or, the attribute value is a part of the measurement report configuration. In this embodiment, the attribute value can be directly defined in the part of the measurement identifier, for example, the attribute value is directly attached after the measurement identifier, or the attribute value can also be defined in the measurement report configuration, for example, in the measurement report configuration The attribute values are attached to the back, which can be flexibly applied to various scenarios.

Manner 2: The condition switching configuration includes the measurement identifier and the attribute value of the measurement identifier; the measurement identifier is used to trigger the condition switching, and the attribute value is used to indicate whether to trigger the measurement report.

In this embodiment, the measurement identifier and its attribute value are defined in the condition switching configuration. The measurement identifier is used to trigger condition switching. When the attribute value meets a certain condition, the measurement report will not be triggered. Optionally, if the attribute value is the second value, the measurement identifier is used to trigger the measurement report; if the attribute value is not the second value, the measurement identifier does not trigger the measurement report. For example, the second value can be TRUE. If the measurement identifier is configured in the condition switching configuration, and the attribute value of the measurement identifier is TRUE, the measurement identifier not only triggers condition switching, but also triggers measurement reporting. The attribute value is FALSE, the measurement identifier is used to trigger condition switching, not to trigger measurement reporting. Or, if the attribute value is the second value, the measurement identifier is not used to trigger the measurement report; if the attribute value is not the second value, the measurement identifier is used to trigger the measurement report. Alternatively, the second value may also be other parameters such as FALSE, 0, or 1, which is not limited in this embodiment.

It should be noted that the first value and the second value in the embodiment of the present application may be the same or different, which is not limited in the present application.

Optionally, the attribute value is part of the measurement identifier; or, the attribute value is part of the conditional switching configuration. In this embodiment, the attribute value can be directly defined in the part of the measurement identifier, for example, the attribute value is directly attached after the measurement identifier, or the attribute value can also be defined in the conditional switching configuration, for example, in the conditional switching configuration The attribute values are attached to the back, which can be flexibly applied to various scenarios.

In the conditional switching method provided in this embodiment, the conditional switching configuration reuses the measurement identifier configured in the measurement report, and sets the attribute value for the measurement identifier to define whether the measurement identifier is used to trigger the measurement report. The measurement identifier can be configured in the measurement report configuration , Can also be set in the condition switching configuration, through its attribute value can define the trigger condition switching of the measurement identification and the function of triggering the measurement report, the configuration is flexible and simple, and it can be applied to a variety of scenarios.

Embodiment 2: The conditional handover configuration reuses the measurement identifier definition in the measurement report configuration, and sets a specific cell set for the measurement identifier, so that the measurement identifier triggers the measurement report or does not trigger the measurement report for the cells in the specific cell set. In this embodiment, in the prior art, a whitelist is used to indicate the cells used for measurement and reporting. Therefore, the existing whitelist configuration can be used to enable the UE to perform operations on the cells in the whitelist cell list associated with the measurement identifier. Measurement report, no measurement report is triggered for cells not in the whitelisted cell list.

Manner 3: The handover condition configuration includes the measurement identifier, and the measurement report configuration includes a whitelisted cell list; the whitelisted cell list is empty, and the measurement identifier associated with the measurement object in the measurement report configuration is not used to trigger the measurement report.

In this embodiment, the measurement identifier is configured in the handover condition configuration, and the whitelist cell list is allowed to be empty. For example, the whitelist cell list is NULL. In this case, the measurement object in the measurement report configuration is associated with The measurement identifier cannot be used to trigger measurement reporting, but used for condition switching.

Method 4: The handover condition configuration includes the measurement identifier, and the measurement report configuration includes the whitelisted cell list; the whitelisted cell list is not empty; if the cell associated with the measurement identifier is a cell in the whitelisted cell list, the measurement identifier is used to trigger the measurement report; If the cell associated with the measurement identifier is not a cell in the whitelisted cell list, the measurement identifier does not trigger measurement reporting.

In this embodiment, the whitelisted cell list may include certain cells, and these cells are the cells that need to be measured and reported, rather than the target cells that need to be conditionally switched. For cells outside the whitelist cell list, the UE uses the measurement identifier in the conditional switching configuration to determine whether conditional switching is required. For example, if the cell outside the whitelist cell list is a cell associated with the measurement identifier, conditional switching is required ; If the cell outside the whitelist cell list is not the cell associated with the measurement identity, no conditional switching is required.

Manner 5: The handover condition configuration includes the measurement identifier and the target cell identifier; the measurement identifier does not trigger measurement reporting for the target cell, and triggers conditional handover for the target cell. In this embodiment, the target cell can also be set in the handover condition configuration, so that the target cell associated with the measurement identifier does not trigger the measurement report and triggers the conditional handover.

In the conditional handover method provided in this embodiment, the conditional handover configuration reuses the measurement identifier definition in the measurement report configuration, and sets a specific cell set for the measurement identifier, so that the measurement identifier triggers the measurement report or does not trigger the measurement report for the cells in the specific cell set. The existing whitelist is used to define whether the measurement identifier triggers the measurement report. The existing whitelist mechanism in the measurement report configuration is reasonably used, which can reduce the signaling overhead. It can also trigger the measurement report mechanism for some special cells with flexibility. Strong.

The third embodiment: the conditional handover configuration reuses the measurement ID definition of the measurement report configuration, and the measurement ID used for the conditional handover or the cell cannot be used for the measurement report through the protocol.

Manner Six: The measurement report configuration includes a measurement identifier, which is used to trigger condition switching and is not used to trigger measurement report.

In this embodiment, the protocol stipulates that a certain measurement identifier is defined for conditional switching, and the measurement identifier as a whole is not used for measurement reporting. In this manner, the measurement identifier can be included in the measurement reporting configuration for definition, but The protocol stipulates that if the measurement identifier is used for condition switching, the measurement identifier does not need to trigger measurement reporting.

Optionally, the measurement identifier is not used to trigger measurement reporting, and includes at least one of the following:

The measurement identifier does not trigger measurement reporting for candidate cells associated with conditional handover;

The measurement identifier does not trigger measurement reporting for candidate cells that are not associated with conditional handover.

In this embodiment, the conditional handover can be associated with the cell. For example, a candidate cell is configured in the conditional handover configuration. If the measurement object associated with the measurement identifier is a candidate cell associated with the conditional handover, the measurement identifier does not trigger the measurement Reporting, if the measurement object associated with the measurement identifier is not a candidate cell associated with the conditional handover, the measurement identifier triggers the measurement report. For example, when the conditional handover is associated with candidate cells A and B, when the UE evaluates that the trigger condition is met for cell A/B, only the conditional handover is performed without measurement report; on the contrary, when the UE evaluates the trigger condition for the cell A/B Other cells outside, such as C, can perform measurement reporting when they meet the measurement reporting conditions.

Optionally, if the cell associated with the measurement identifier is a cell in the whitelist list in the measurement report configuration, the measurement identifier is used to trigger the measurement report; if the cell associated with the measurement identifier is not in the whitelist list in the measurement report configuration Cell, the measurement identifier is not used to trigger measurement reporting.

In this embodiment, the protocol stipulates that as long as a certain measurement identifier is used for conditional handover, the measurement identifier is not used for measurement reporting for the target cell used for the conditional handover. In this way, it can be limited to the existing whitelisted cell list, that is, the measurement identifier will trigger the measurement report for the cells in the whitelisted cell list; the measurement identifier will not trigger the measurement report for the cells not in the whitelist. Whether it can trigger conditional switching needs to be determined according to the switching conditions in the conditional switching configuration.

In the conditional handover method provided in this embodiment, the conditional handover configuration reuses the measurement ID definition of the measurement report configuration, the measurement ID used for conditional handover is specified by the protocol or the cell cannot be used for measurement report, and the function of the measurement ID is directly specified by the protocol. It is easy to implement and not prone to ambiguity, ensuring the accuracy of condition triggering and measurement reporting.

Embodiment 4: The conditional switching configuration separately defines the measurement identifier.

Manner Seven: The condition switching configuration includes a measurement identifier, which is used to trigger condition switching.

In this embodiment, the condition switching configuration does not reuse the measurement identification configured for measurement reporting, but defines a measurement identification separately, which is defined as triggering condition switching and does not trigger measurement reporting.

Further, when the measurement identifier is separately defined in the condition switching configuration, optionally, the measurement report configuration and/or the condition switching configuration include the measurement object used to define the measurement identifier. Optionally, the measurement report configuration includes the measurement object, and the condition switching configuration includes some or all parameter values of the measurement object corresponding to the same measurement identifier in the measurement report configuration. Optionally, the measurement reporting configuration and/or the condition switching configuration include measurement reporting conditions for defining the measurement identifier. Optionally, the measurement report configuration includes measurement report conditions, and the condition switching configuration includes some or all parameter values of the measurement report conditions corresponding to the same measurement identifier in the measurement report configuration.

In this embodiment, the measurement object can be configured in the measurement report configuration and/or the condition switching configuration. In the case of and, the condition switching configuration can perform some/all parameter values for the measurement objects with the same ID in the measurement report configuration. Rewritten to be used in the case of conditional switching. The measurement reporting conditions can be configured in the measurement reporting configuration and/or the condition switching configuration.
