The following example 1 and example 2 further illustrate the measurement information configuration method of the present invention.

Example 1

This example provides a measurement information configuration method for a communication system after a 5G network covers high-speed rail. The communication system includes a base station and a terminal, and the base station includes independently set CU and DU, among which physical layer functions, MAC (Medium Access Control, media access control) layer functions, and RLC (Radio Link Control, radio link control) Layer functions are implemented on the DU, and the remaining functions are implemented in the CU. The CU and DU are connected and communicated through the F1 interface, and the DU and the terminal are connected and communicated through the Uu interface.

As shown in Figure 5, this example provides a measurement information configuration method, which may include the following steps:

Step 101: A terminal (UE) accesses (or switches in or re-establishes in) an NR (New Radio) cell, and establishes an RRC connection.

Step 102: The DU judges the current moving speed of the UE, and determines the moving speed status of the UE;

The DU receives the uplink signal sent by the terminal. Due to the relative movement between the terminal and the DU, a Doppler frequency shift (frequency offset) is generated between the frequency of the signal received by the DU receiver and the frequency of the signal sent by the terminal. The frequency offset value determines the moving speed state of the terminal; wherein, the larger the frequency offset value, the faster the moving speed of the terminal; when the frequency offset value is greater than or equal to the threshold, it is determined that the moving speed state of the terminal is a high-speed moving state; When the frequency offset value is less than the threshold, it is determined that the moving speed state of the terminal is a low-speed moving state;

Step 103: The DU informs the CU through the F1 interface that the current speed of the UE is indicated as a high-speed movement state or a low-speed movement state.

Step 104: After the CU receives the speed indication from the DU, if the speed indication is a high-speed movement state, the CU formulates a proprietary measurement configuration strategy; if the speed indication is a low-speed movement state, the CU formulates a common measurement configuration strategy.

Among them, the proprietary measurement configuration strategy is specifically applicable to high-speed mobile terminals. The common measurement configuration strategy is applicable to all terminals accessing the cell.

For example, when the terminal is moving at a high speed, configure the terminal to report the measurement report at a shorter time interval (compared to the regular time interval of the common measurement configuration strategy), configure the terminal to report the measurement report to multiple times, and configure the measurement event of the terminal It is a proprietary measurement event (for example, when the signal quality of the neighboring cell is higher than a preset threshold, the terminal is triggered to report a measurement report);

When the terminal is moving at a low speed, configure the terminal to report measurement reports at regular time intervals, configure the number of times the terminal reports measurement reports to one, and configure the measurement event of the terminal as a general measurement event (for example, when the signal quality of the neighboring cell is higher than the current terminal When the signal quality of the serving cell is triggered, the terminal is triggered to report a measurement report);

Among them, the terminal moving speed is different, the configuration threshold of the measurement event, the reporting interval of the measurement report, and the number of times of reporting may all be different, and the timing of the terminal reporting the measurement report will be different.

Step 105: After the CU formulates a measurement configuration strategy, it constructs an RRC measurement reconfiguration message, and sends it to the DU through a DL RRC MESSAGE TRANSFER message.

Among them, the RRC measurement reconfiguration message (message on the Uu port) is included in the DL RRC MESSAGE TRANSFER message (message on the F1 port), which is first forwarded by the CU to the DU through the DL RRC MESSAGE TRANSFER message. After receiving the message, the DU takes out the message The RRC measurement reconfiguration message contained in;

Step 106: The DU issues an RRC measurement reconfiguration message to the UE through the Uu port.

Step 107: After receiving the RRC measurement reconfiguration message, the UE obtains measurement configuration information from the RRC measurement reconfiguration message, and validates the corresponding measurement configuration;

After the corresponding measurement configuration takes effect, the terminal starts measurement, and when the conditions in the measurement configuration (for example, the measurement threshold and the measurement report interval in the measurement event) are met, the terminal reports the measurement report and performs handover.

Wherein, the measurement configuration information includes at least one of the following information: the time interval for the terminal to report the measurement report, the number of times the terminal reports the measurement report, and the measurement event;

Wherein, the terminal reports the measurement report under the condition that the measurement threshold and the measurement report interval are satisfied according to the measurement configuration.

Example 2

Step S201: A terminal (UE) accesses (or switches in, or re-establishes in) an NR (New Radio) cell, and establishes an RRC connection.

Step S202: The DU judges the current moving speed of the UE, and determines the moving speed status of the UE.

Step S203: the DU judges whether the terminal is in a high-speed moving state, if yes, execute step S204, otherwise, execute step S205;

Step S204: The DU informs the CU through the F1 interface that the current speed of the terminal indicates a high-speed movement state. After receiving the speed indication from the DU, the CU formulates a proprietary measurement configuration strategy, and then goes to step S206;

Among them, the proprietary measurement configuration strategy is specifically applicable to high-speed mobile terminals.

Step S205: The DU informs the CU through the F1 interface that the current terminal speed indicates a low-speed movement state. After the CU receives the low speed indication from the DU, it formulates a common measurement configuration strategy;

Among them, the common measurement configuration strategy is applicable to all terminals accessing the cell.

Step S206: The CU constructs an RRC measurement reconfiguration message, and sends it to the DU through a DL RRC MESSAGE TRANSFER message, and the DU issues an RRC measurement reconfiguration message to the terminal through the Uu port;

Step S207: After receiving the RRC measurement reconfiguration message, the terminal obtains measurement configuration information from the RRC measurement reconfiguration message, and validates the corresponding measurement configuration;

After the corresponding measurement configuration takes effect, the terminal starts measurement, and when the conditions in the measurement configuration are met, it reports a measurement report and performs handover.

Step S208: The DU detects whether the moving speed status of the terminal has changed, if yes, execute step S209, otherwise, execute step S215;

Among them, when the terminal establishes an RRC connection with the DU, the DU side can continuously obtain the frequency offset value of the uplink signal (such as PUSCH) sent by the terminal, and judge the mobile speed state of the terminal through the frequency offset value. When the frequency offset value changes, Step S209 is executed when the determined moving speed status changes.

Step S209: The DU notifies the CU of the change in the moving speed status of the terminal through the F1 interface;

Step S210: Determine whether the moving speed state of the terminal changes from low speed to high speed, if yes, execute step S211, otherwise, execute step S212;

Step S211: The CU changes the current measurement configuration strategy of the terminal, deletes the common measurement configuration strategy, adds a dedicated measurement configuration strategy (for high-speed mobile terminals), and then goes to step S213;

Step S212: The CU changes the current measurement configuration strategy of the terminal, deletes the proprietary measurement configuration strategy, and adds a common measurement configuration strategy;

Step S213: The CU constructs an RRC measurement reconfiguration message, and sends it to the DU through a DL RRC MESSAGE TRANSFER message, and the DU issues an RRC measurement reconfiguration message to the terminal through the Uu port;

Step S214: After receiving the RRC measurement reconfiguration message, the terminal obtains measurement configuration information from the RRC measurement reconfiguration message, validates the new measurement configuration, and deletes the old measurement configuration;

Step S215: When the measurement result meets the measurement configuration condition, the terminal reports an RRC measurement report (Measurement Report) to the DU, and the DU constructs a UL RRC MESSAGE TRANSFER through the F1 interface to deliver the RRC measurement report message to the CU.

Step S216: The CU performs a corresponding handover according to the content of the measurement report.
