Detailed ways

In order to facilitate the understanding of the technical solutions of the embodiments of the present application, first, a brief introduction of the related technologies of the present application is given as follows.

Radio resource control (radio resource control, RRC) status:

In the embodiments of the present application, the RRC state of the terminal device can be divided into the RRC connected state and the RRC non-connected state. When the terminal device is in the RRC connected state, there is an RRC connection between the terminal device and the network device, and when the terminal device is in the RRC non-connected state, there is no RRC connection between the terminal device and the network device (such as an access network device).

Exemplarily, the RRC connected state may include the RRC connected state (RRC_CONNECTED), and the RRC non-connected state may include at least one of the RRC inactive state (RRC_INACTIVE) and the RRC idle state (RRC_IDLE).

It is understandable that this application does not limit the RRC non-connected state to only include the RRC inactive state and the RRC idle state, and other RRC non-connected states may appear in future protocols.

Take the new radio (NR) system as an example. In NR, when the terminal device is in the RRC connection state, the terminal device has established a connection with the access network device and the core network device, and the terminal device can connect to the network The device performs data transmission; when the terminal device is in the RRC inactive state, the terminal device retains the link between the terminal device and the core network device, and releases the link with the access network device. At this time, the terminal device and the access network device save the context of the terminal device. When there is data to be transmitted, the terminal device can quickly restore the link between the terminal device and the access network device. When the terminal device is in the RRC idle state, the terminal device releases the link between the terminal device and the access network device, as well as the link between the terminal device and the core network device.

Exemplarily, the transition of the above three states may be as shown in FIG. 1. When the terminal device is in the RRC idle state, it can enter the RRC connected state by establishing an RRC connection with the network device; when the terminal device is in the RRC connected state, the network device can release the RRC connection of the terminal device and configure the terminal device to enter the RRC inactive state or RRC idle state; when the terminal device is in the RRC inactive state, it can initiate a request to restore the RRC connection, and the network device can configure the terminal device to enter the RRC connected state or the idle state.

It is understandable that the above RRC state is only an example, and should not constitute any limitation to this application. This application does not exclude the definition of other possible names in future agreements to replace existing names, but with the same or similar characteristics, or other states may also appear.

At this time, the first threshold may be determined by the terminal device itself, that is, the terminal device may not determine the first threshold according to the related configuration information of the network device; or, in another implementation scenario of the embodiment of the present application, the first threshold It can be stipulated by agreement.

Among them, after the terminal device is in the RRC disconnected state, the serving cell of the terminal device can be measured to obtain the measurement result of the serving cell.

Optionally, the measurement result of the serving cell may include at least one of the following: RSCP, RSRP, RSRQ, SNR, SINR, RSSI, or other signal quality. In the case where the first threshold includes multiple types of thresholds:

In a possible implementation manner, the terminal device measures the serving cell according to the type of each threshold included in the first threshold, that is, the measurement result of the serving cell corresponds to the type of the first threshold one-to-one. In the embodiment of the present application, the types of the first threshold are RSRQ threshold and RSRP threshold, and correspondingly, the measurement result of the serving cell includes RSRQ and RSRP as an example for description.

Optionally, in this implementation manner, when comparing the magnitude relationship between the measurement result of the serving cell of the terminal device and the first threshold, each measurement result may be compared with a corresponding type of threshold.

Optionally, in this implementation manner, the measurement result of the serving cell and the first threshold satisfy a certain magnitude relationship (for example, less than or equal to), and each measurement result of the serving cell and the corresponding type of threshold in the first threshold may satisfy the Size relationship. For example, the measurement result of the serving cell is less than or equal to the first threshold may be: the RSRQ of the serving cell is less than or equal to the RSRQ threshold in the first threshold, and the RSRP of the serving cell is less than or equal to the PSRP in the first threshold.

In another possible implementation manner, the terminal device measures the serving cell according to a partial threshold included in the first threshold, that is, the number of measurement results of the serving cell is less than or equal to the number of types of the first threshold. In the embodiment of the present application, the type of the first threshold is the RSRQ threshold and the RSRP threshold, and the measurement result of the serving cell is the RSRP as an example for description.

Optionally, part of the threshold included in the first threshold may be one or more thresholds indicated by the network device to the terminal device, which is not specifically limited in the embodiment of the present application.

Optionally, in this implementation manner, when comparing the measurement results of the serving cell of the terminal device with the first threshold, the measurement results of the serving cell may be compared with the corresponding type of threshold among the partial thresholds included in the first threshold. Compare. For example, the type of the first threshold is RSRQ threshold and RSRP threshold, and part of the threshold included in the first threshold is RSRP threshold. If the measurement result type of the serving cell is RSRP, the RSRP of the serving cell and the corresponding RSRP threshold in this part of the threshold can be combined Compare.

Optionally, in this implementation manner, the measurement result of the serving cell and the partial threshold included in the first threshold satisfy a certain magnitude relationship (for example, less than or equal to), which may be the measurement result of the serving cell and the partial threshold included in the first threshold The thresholds of the corresponding type in the corresponding type meet the size relationship. For example, the measurement result of the serving cell is less than or equal to the first threshold may be: the RSRP of the serving cell is less than or equal to the RSRP in the first threshold.

S702. The terminal device performs the first measurement.

That is, when the terminal device is in the RRC disconnected state and the measurement result of the serving cell of the terminal device is less than or equal to the first threshold, the first measurement is performed, and the first measurement is used to measure at least one frequency point.

It should be noted that in the implementation of this application, "measurement result" can also be referred to as "measurement quantity", which is used to characterize signal quality, and the two can be replaced with each other, or "measurement result" can also be referred to as "signal quality"; "First measurement" can also be called "early handover measurement", and the two can be replaced with each other.

Optionally, the early handover measurement may refer to the measurement used for handover performed when the terminal device is in the RRC non-connected state, that is, the first measurement may refer to the measurement used for early handover. Or, the early handover measurement may refer to the measurement performed by the terminal device in the RRC disconnected state when the measurement result of the serving cell is less than or equal to the first threshold.

Optionally, the at least one frequency point measured by the first measurement may include the same frequency point as the frequency point of the serving cell of the terminal device, or may include a frequency point different from the frequency point of the serving cell of the terminal device. The at least one frequency point may include a frequency point under the same system (or standard) as the system (or standard) of the serving cell of the terminal device, or may include a system (or standard) different from the system (or standard) of the serving cell of the terminal device The frequency point under (or standard) is not specifically limited in the embodiment of the present application.

Optionally, the measurement can be granular in at least one of the following: cell, beam, synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SSB (or SS/PBCH Block)), channel state information Reference signal (channel-state information reference signal, CSI-RS), air interface technology (numerology), slicing (slicing), or bandwidth part (BWP). Among them, different air interface technologies correspond to different subcarrier intervals.

It can be understood that beam, SSB, CSI-RS, air interface technology, slice, and BWP are related attributes of a cell. For example, a cell may include multiple beams, and each beam is used to carry one SSB, namely beam, SSB, CSI -RS, air interface technology, slicing, and BWP are finer granularities than cells.

That is, the terminal device performing the first measurement may include: the terminal device determines the cell on the above at least one frequency point, and then executes it with at least one of cell, beam, SSB, CSI-RS, air interface technology, slice, or BWP as the granularity Measurement.

In the embodiment of the present application, any cell measured by the terminal device is referred to as the first cell. It is understandable that the terminal device can measure all or part of the cells on all or part of the above at least one frequency point. That is, all the first cells measured by the terminal equipment may include one or more cells on the first frequency point, and the first frequency point is one or more frequency points belonging to at least one frequency point to be measured for the first measurement. .

Exemplarily, the first measurement is used to measure frequency point 1, frequency point 2, and frequency point 3. The cells on frequency point 1 are cell A and cell B, and the cells on frequency point 2 are cell C and cell D, For example, the cells on frequency 3 are cell E and cell F. The first frequency point can be one or more of the 3 frequency points. For example, the first frequency point is frequency point 1 and frequency point 3. The first cell is one or more cells on frequency point 1 and one or more cells on frequency point 3. For example, all the first cells are cell A, cell B, and cell E.

Optionally, the granularity of the measurement result may be the same as the granularity of performing the measurement, or may be determined based on the granularity of performing the measurement. For example, when the beam is used as the granularity of performing the measurement, the granularity of the measurement result may be the beam or the cell, for example, , The measurement result of the cell is the weighted result of the beam measurement result. That is, in the embodiment of this application, the measurement result of the cell may be at least one of the following: the measurement result with the cell as the granularity, the measurement result with the cell beam as the granularity, the measurement result with the cell SSB as the granularity, and the cell CSI-RS as the granularity. The measurement result of the granularity, the measurement result of the granularity using the air interface technology used by the cell, the measurement result of the granularity using the cell slice, or the measurement result of the granularity using the cell BWP.

Optionally, the measurement result may include at least one of the following: RSCP, RSRP, RSRQ, SNR, SINR, RSSI, or other signal quality.

Optionally, the measurement result can be obtained by measuring at least one of the following: downlink synchronization channel, channel-state information reference signal (channel-state information reference signal, CSI-RS), demodulation reference signal (demodulation reference signal, DMRS), cell-specific reference signal (CRS) signal, synchronization signal (synchronization signal, SS), synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH Block, or SSB) , Or other downlink signals.

Exemplarily, the measurement result is obtained by measuring CSI-RS, and the measurement result includes RSRP as an example. The terminal device can measure the CSI-RS of different beams in the cell to obtain the RSRP with the beam granularity, that is, to obtain the different beams in the cell. Measurement results.

Or, exemplarily, the measurement result is obtained by measuring SSB, and the measurement result includes RSRQ as an example. The terminal device can measure different SSBs in the cell to obtain RSRQ with SSB granularity, that is, obtain the measurement results of different SSBs in the cell.

Optionally, the terminal device may record the measurement result information of the first cell during the process of performing the first measurement. Wherein, the measurement result information of the first cell includes identification information related to the first cell, or includes identification information related to the first cell and a measurement result of the first cell. The measurement result information of the first cell may also be referred to as neighboring cell information of the serving cell of the terminal device.

Optionally, the identification information related to the first cell may include the cell global identifier (CGI) of the first cell, the physical cell identifier (PCI) of the first cell, and the identifier of the first frequency point , Or at least one of the cell identities of the first cell. The identification information related to the first cell may also include at least one of the following: beam identification of the first cell, synchronization signal/physical broadcast channel block identification of the first cell, CSI-RS identification of the first cell, and The air interface technology identifier used by a cell, the slice identifier of the first cell, and the BWP identifier of the first cell.

Based on this solution, reasonable measurements can be performed in the RRC disconnected state, which can facilitate network equipment to make more reasonable judgments and improve capacity performance. For example, since the terminal device performs frequency measurement when it is in the RRC disconnected state, if the terminal device detects that there is a neighboring cell with good quality, it can report the neighboring cell to the network device when it is in the RRC connected state. The network equipment can obtain the neighboring cell information of the terminal device in time, so as to optimize the capacity based on the neighboring cell information in time, such as handover judgment; in the case that the terminal device does not measure the neighboring cell with better quality, the terminal equipment When in the RRC connection state, it can send indication information to the network device indicating that the neighboring cell has not measured good quality, so that the network device can optimize the capacity more reasonably according to the indication, such as releasing the terminal device, or not passing the indication information Indicate that the terminal device has not measured a cell with better quality, which can enable the network device to preferentially switch to terminal devices that have reported neighboring cell information when performing capacity optimization.

Optionally, in an implementation scenario of the embodiment of the present application, in the foregoing step S701, the first configuration information determined by the terminal device may further include one or more of the following: measurement target configuration information, second threshold, or measurement Time information. The description of each parameter is as follows:

The measurement target configuration information configures at least one frequency point to be measured for the first measurement. The measurement target configuration information may include frequency point information of each frequency point in at least one frequency point, for example, an absolute radio frequency channel number (ARFCN) of each frequency point. The measurement target configuration information can also configure the subcarrier spacing information of each frequency point, and/or the synchronization signal of each frequency point/physical broadcast channel block measurement time configuration (SS/PBCH block measurement timing configuration, SMTC), SMTC can be configured At least one of the period of the SSB, the length of the time domain, and the offset of the start position.

The second threshold is used for the terminal device to determine whether to report the measurement result information of the first cell. Optionally, the second threshold may be an absolute threshold. In this case, the second threshold may be greater than the first threshold; or, the second threshold may be a relative threshold (or called a threshold offset).

Optionally, when the second threshold is an absolute threshold, the type of the second threshold may be at least one of the following: RSCP threshold, RSRP threshold, RSRQ threshold, SNR threshold, SINR threshold, RSSI threshold, or other signal quality Threshold; when the second threshold is a relative threshold, the type of the second threshold can be at least one of the following: RSCP relative threshold, RSRP relative threshold, RSRQ relative threshold, SNR relative threshold, SINR relative threshold, RSSI relative threshold, Or other relative thresholds of signal quality.

The measurement time information indicates the maximum length of time for the terminal device to perform the first measurement. Exemplarily, in the foregoing step S702, the terminal device may start the first timer at the moment when the first measurement is started. The length of the first timer is the length of time indicated by the measurement time information. During the running time of the first timer, the terminal device performs the first measurement; after the first timer is stopped, the terminal device can stop the first measurement, which can prevent the terminal device from continuously measuring before accessing the network device, Reduce the power consumption of terminal equipment.

Optionally, as a possible implementation manner, if the terminal device enters the RRC connection state within the running time of the first timer, the terminal device may also stop the first measurement.

Optionally, in an implementation scenario of the embodiment of the present application, the second threshold and/or the maximum time length indicated by the measurement time information may also be specified in the protocol, or may be determined by the terminal device itself. There is no specific restriction on this.

Optionally, after the terminal device performs the first measurement, a neighboring cell with better quality may be measured, or a neighboring cell with better quality may not be measured.

In an implementation scenario of the embodiment of the present application, in the above step S702, when the terminal device performs the first measurement, in the case that the second threshold is an absolute threshold, and the measurement result of the first cell is greater than or equal to the second threshold, the terminal The device determines to report the measurement result information of the first cell; or, when the second threshold is a relative threshold (or threshold offset), the difference between the measurement result of the first cell and the measurement result of the serving cell of the terminal device is greater than or equal to In the case of the second threshold, the terminal device determines to report the measurement result information of the first cell. That is, in the embodiment of the present application, when the measurement result of the first cell is greater than or equal to the second threshold, or the difference between the measurement result of the first cell and the measurement result of the serving cell of the terminal device is greater than or equal to the second threshold. When the threshold is reached, the terminal device determines to report the measurement result information of the first cell. At this point, it can be considered that the terminal equipment measures a good neighboring cell.

Optionally, the manner of comparing the measurement result of the first cell with the second threshold may refer to the manner of comparing the measurement result of the serving cell with the first threshold, which will not be repeated here.

It is understandable that since the terminal device is in the RRC disconnected state when the first measurement is performed, when the terminal device determines to report the measurement result information of the first cell, it cannot immediately send the measurement result information of the first cell to the network device. Therefore, The terminal device may record the measurement result information of the first cell, and when the terminal device switches to the RRC connection state, it sends the recorded measurement result information of the first cell to the network device.

Optionally, in this scenario, the terminal device recording the measurement result information of the first cell in the foregoing step S702 may be: the terminal device recording the measurement result information of the first cell that meets the second threshold condition. In the embodiment of the present application, the first cell whose measurement result is greater than or equal to the second threshold or the first cell whose measurement result is greater than or equal to the measurement result of the serving cell of the terminal device is referred to as the first cell It is the first cell that meets the second threshold condition.

That is, after obtaining the measurement result information of the first cell, the terminal device compares the measurement result of the first cell with the second threshold, and when the measurement result information of the first cell meets the second threshold condition, the first cell is recorded The measurement result information.

Optionally, the measurement result information of the first cell recorded by the terminal device is not long-term effective.

In a possible implementation manner, the measurement result information of the first cell is valid for a preset period of time starting from the time when the terminal device completes the recording. Within the preset time period, if the terminal device does not enter the RRC connection state or the terminal device does not send a measurement report to the network device, the terminal device may delete the measurement result information of the first cell, or the terminal device may consider the measurement result information to be invalid. The terminal device does not send the measurement result information after entering the RRC connected state.

In another possible implementation manner, when the terminal device records the measurement result information of the first cell, the second timer may be started. During the running time of the second timer, the measurement result information of the first cell is valid; if the second timer expires and the terminal device does not enter the RRC connection state or the terminal device does not send a measurement report to the network device, the terminal device can delete the measurement report. The measurement result information of the first cell, or the terminal device may consider the measurement result information to be invalid, and the terminal device does not send the measurement result information after entering the RRC connected state. The time length of the second timer may be predefined by the protocol, or may be sent by the network device to the terminal device.

In another possible implementation manner, if the terminal device enters the RRC connection state or before the terminal device sends a measurement report to the network device, the quality of the serving cell of the terminal device is improved, for example, the measurement result of the serving cell is greater than or equal to the third threshold , The terminal device can delete the recorded measurement result information of the first cell. Optionally, if the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device may also stop the first measurement, and subsequently does not send a measurement report of any cell obtained through the first measurement to the network device.

In another possible implementation manner, the terminal device may start a third timer when recording the measurement result information of the first cell. Within the time allowed by the third timer, if the quality of the serving cell of the terminal device improves, for example, the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device can stop the third timer and delete the recorded first cell The measurement result information. Optionally, if the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device may also stop the first measurement, and subsequently does not send a measurement report of any cell obtained through the first measurement to the network device.

Optionally, the third threshold may be the same as the first threshold or different from the first threshold, which is not specifically limited in the embodiment of the present application.

In another possible implementation manner, the terminal device may perform multiple measurements for the first cell in step S702. In the case where the terminal device records the measurement result information of the first cell after measuring the first cell for the nth time, if the measurement result of the first cell obtained by the n+1th measurement is greater than or equal to the second threshold, or The difference between the measurement result of the n+1th measurement and the measurement result of the serving cell of the terminal device is greater than or equal to the second threshold, and the terminal device updates the recorded measurement result information of the first cell to the measurement result of the n+1th measurement. Measurement result information; or, if the measurement result of the cell obtained by the n+1th measurement is less than or equal to the second threshold, or the difference between the n+1th measurement result and the measurement result of the terminal equipment serving cell is less than or equal to The second threshold, the terminal device deletes the recorded measurement result information of the first cell obtained by the nth measurement.

In another implementation scenario of the embodiment of the present application, in the above step S702, when the terminal device performs the first measurement, the measurement result of the first cell is less than or equal to the second threshold, or the measurement result of the first cell matches the terminal device In the case that the difference between the measurement results of the serving cell is less than or equal to the second threshold, the terminal device may not record the measurement result information of the first cell. At this time, it can be considered that the terminal equipment has not measured a good neighboring cell.

Optionally, when the terminal device is in the RRC connection state, if the terminal device stores the measurement result information of one or more first cells, the following step S703a may be performed; or, if the terminal device does not store any first cell For the measurement result information of a cell, the following step S703b can be executed.

Optionally, when the terminal device is in the RRC connected state, the measurement result information of the first cell is stored, which can be understood as: the terminal device stores one or more latest or valid measurement result information of the first cell; The reason why the terminal device does not store any measurement results of the first cell may be that the terminal device has never measured a neighboring cell with better quality (for example, there is no first cell that meets the second threshold condition), or the terminal device may be due to the effective duration, etc. The reason is that the measurement result information of the neighboring cell with better quality measured before is deleted.

Optionally, the serving cell of the terminal device when the terminal device is in the RRC connected state may be the same as the serving cell of the terminal device in step S701. For example, from step S701 to this step S703a, S703b or S704, the serving cell of the terminal device has not changed. At this time, the network device in the following steps S703a, S703b, or S704 may be the network device to which the serving cell of the terminal device belongs in step S701; or, the serving cell when the terminal device is in the RRC connection state may be the same as the terminal device in step S701. The serving cell of the device is different. For example, in the process from step S701 to step S703a, S703b, or S704, the serving cell of the terminal device changes, and the network device to which the serving cell belongs may also change.

The following embodiments are first described by taking as an example that the serving cell of the terminal device has not changed. It can be understood that when the serving cell of the terminal device has not changed, it is not limited to this implementation manner.

S703a. The terminal device sends a first measurement report to the network device. Correspondingly, the network device receives the first measurement report from the terminal device.

That is, when the terminal device is in the RRC connection state, the first measurement report is sent to the network device.

Optionally, the terminal device may generate a first measurement report according to all or part of the recorded measurement result information of the first cell, and then send the first measurement report to the network device.

Optionally, the first measurement report may include all measurement result information of the first cell recorded by the terminal device, or the first measurement report may include part of the measurement result information of the first cell recorded by the terminal device.

It is understandable that the measurement result information of the first cell recorded by the terminal equipment may be the measurement result information of the first cell that meets the second threshold condition, or it may be the first cell that is recorded without the second threshold condition judgment. Measurement result information.

Exemplarily, if the size of the measurement result information of all the first cells recorded by the terminal device (size) is less than or equal to the signaling size of the allowed measurement report, the first measurement report may include the measurement result information of all the first cells; if The size of all the measurement result information of the first cell recorded by the terminal equipment is greater than the signaling size of the allowable measurement report. The first measurement report may include part of the measurement result information of the first cell, for example, according to the time sequence of recording the measurement result information, select The measurement result information of part of the first cell recorded first or most recently is reported as the content included in the first measurement report, or the measurement result information of part of the first cell is selected as the first measurement result according to the size of the measurement result (measurement value) of the cell. The content included in the measurement report is reported, such as sorting in descending or ascending order according to the size of the measurement result, and selecting the measurement result information of the first cell with a larger measurement result.

Optionally, the terminal device can use the RRC setup complete (RRC setup complete) message, the RRC reconfiguration complete (RRC Reconfiguration Complete) message, the RRC reestablishment complete message (RRC Reestablishment Complete) message, and the user equipment information response (UE information response). Message, one or more of the RRC resume complete (RRC resume complete) message sends the measurement result of the first cell to the network device; or, the terminal device can use the message 1 (message 1, msg1) in the random access process One or more of message 3 (message 3, msg3), message 5 (msg5), or message A (message A, msgA) sends the first measurement report to the network device.

Optionally, after the terminal device sends the first measurement report to the network device, the measurement result information of the first cell included in the recorded first measurement report may be deleted.

After receiving the first measurement report, the network device may perform capacity coverage optimization according to the first measurement report. For example, a handover judgment can be made, and the terminal device can be handed over to a neighboring cell with a higher quality.

Optionally, the terminal device may send the first measurement report to the network device in different situations.

In a possible implementation manner, the terminal device may send the first measurement report to the network device based on the instruction of the network device. Exemplarily, when the serving cell is overloaded or capacity is reduced, the network device may send an instruction to report the measurement report to the terminal, for example, the network device may broadcast the instruction; when the terminal device enters the RRC connection state, the terminal device sends the measurement report to the network device The first measurement report.

In another possible implementation manner, the terminal device may send the first measurement report to the network device based on the request of the network device. In this scenario, before step S703a, it further includes: the network device sends request information to the terminal device. Correspondingly, the terminal device receives the request information from the network device. Wherein, the request information is used to request the terminal device to report the first measurement report.

Optionally, the network device may send request information to the terminal device in different situations:

In a possible implementation manner, before step S703a, the method of the embodiment of the present application further includes: the terminal device sends first indication information to the network device, the first indication information is used to indicate that the terminal device has the measurement result of the first cell The information, or the first indication information, is used to indicate that the terminal device has available measurement result information, or is used to indicate that the terminal device has available early handover measurement result information. Correspondingly, the network device receives the first indication information from the terminal device. In this implementation manner, sending the request information by the network device to the terminal device may include: the network device sending the request information to the terminal device according to the first indication information.

In another possible implementation manner, the network device sending the request information to the terminal device may include: after the terminal device is connected to the network device, the network device sends the request information to the terminal device when the serving cell of the terminal device is overloaded or the capacity decreases. Request information.

S703b. The terminal device sends second indication information to the network device. Correspondingly, the network device receives the second indication information from the terminal device.

The second indication information may indicate that there is no first cell that meets the second threshold condition, that is, the terminal device does not have a neighboring cell with better quality. Alternatively, the second indication information may be used to indicate "the first measurement has been started, but there is no first cell that satisfies the second threshold condition".

Optionally, after the network device receives the second indication information, it can confirm in time that the terminal device does not have a neighboring cell with better quality, so as to perform capacity optimization processing in time according to the second indication information. For example, for the case where the first measurement has been performed but the neighboring cell with good quality has not been measured, the network device considers that the neighboring cell of the terminal device does not have a neighboring cell with good quality at this time, and can give priority to capacity optimization Switch the terminal device that reported the measurement report to its neighboring cell with better quality. After that, if the capacity performance of the network device is improved, the terminal device that reports the second indication information may not be switched, or if the capacity performance of the network device is still If it is worse, the terminal device that reports the second indication information can be further released (that is, the RRC connection with the terminal device is disconnected).

Based on this solution, when the terminal device does not detect a good-quality neighboring cell, it can promptly indicate to the network device that there is no good-quality neighboring cell, so that the network device can perform capacity optimization processing according to the instruction in time .

Optionally, in the case that the terminal device does not store the measurement result information of the first cell, the terminal device may also not use the second indication information to indicate that the terminal device does not have a neighboring cell with better quality or indicate that the first measurement has been started. But there is no first cell that meets the second threshold condition".

Exemplarily, the network device can confirm that the terminal device supports the first measurement, but the terminal device does not report the measurement report, and the network device can confirm that the terminal device has not measured a neighboring cell with better quality or has not started the first measurement, so that it can be based on In this case, the capacity is optimized. For example, the terminal device that has reported the measurement report can be preferentially switched to its neighboring cell with better quality, and the terminal device that has not reported the measurement report will not be switched. That is to say, in the case that the terminal device does not send the second indication information, the network device can also obtain the coverage and neighboring area of the location of the terminal device in time, so as to perform capacity optimization processing in time.

S704: The terminal device sends third indication information to the network device. Correspondingly, the network device receives the third indication information from the terminal device.

Wherein, the terminal device sending the third indication information to the network device may include: when the terminal device is in the RRC connection state, the terminal device sending the third indication information to the network device.

Wherein, the third indication information indicates that the measurement result of the serving cell of the terminal device is greater than or equal to the first threshold, or indicates that the terminal device has not started the first measurement.

Optionally, after the network device receives the third indication information, it can learn that the quality of the serving cell of the terminal device is good. When the capacity of the network device decreases and capacity optimization processing is performed, the terminal device may not be switched to another In the cell, the terminal device that has reported the measurement report is handed over to the neighboring cell with better quality, or the terminal device that has reported the second indication information is released first.

Based on this solution, the network device can learn about the terminal device with better quality in the serving cell in time, so as to perform reasonable capacity optimization processing. For example, the terminal device may not be handed over to another cell.

Optionally, the terminal device may not use the third indication information to indicate that the measurement result of the serving cell of the terminal device is greater than or equal to the first threshold, or indicate that the terminal device has not started the first measurement.

Exemplarily, the network device can confirm that the terminal device supports the first measurement, but the terminal device does not report the measurement report, and the network device can confirm that the terminal device has not measured a neighboring cell with better quality or has not started the first measurement, so that it can be based on In this case, the capacity is optimized. For example, the terminal device that has reported the measurement report can be preferentially switched to its neighboring cell with better quality, and the terminal device that has not reported the measurement report will not be switched. That is to say, in the case that the terminal device does not send the third instruction information, the network device can also obtain the coverage and neighboring area of the location of the terminal device in time, so as to perform capacity optimization processing in time.

In summary, in an implementation scenario of the embodiment of the present application, multiple terminal devices served by the network device can execute the measurement method provided in the embodiment of the present application. When the network device performs capacity optimization, the measurement report may be reported first. Of the terminal equipment is switched to a better quality cell. After that, if the capacity performance of the network device is still poor, among the terminal devices that report the second indication information and the third indication information, the terminal devices that have reported the second indication information may be released first. For the terminal device that reports the third indication information, when performing capacity optimization, the network device may not switch the terminal device to another cell, or may not release the terminal device. For a terminal device that does not report the measurement report, the second indication information, or the third indication information, the network device may not switch the terminal device to another cell or not release the terminal device when performing capacity optimization.

Optionally, the embodiment of the present application also provides an implementation manner when the serving cell of the terminal device changes.

In this scenario, optionally, the terminal device may receive the area information sent by the network device in step S701, where the area information is used to indicate the effective area for performing the first measurement. The area information may include identification information of at least two cells, indicating that the effective area for performing the first measurement is the at least two cells, and the at least two cells include the first serving cell. In the embodiment of this application, the serving cell before the change (that is, the serving cell of the terminal device in step S701) is referred to as the first serving cell, and the serving cell after the change (that is, the terminal device when the terminal device is in the RRC connection state) is referred to as the first serving cell. The serving cell is called the second serving cell.

When the terminal device moves from the first serving cell to the second serving cell, that is, when the serving cell of the terminal device changes from the first serving cell to the second serving cell, the terminal device can determine whether the second serving cell belongs to the effective area indicated by the area information .

In the case that the second serving cell does not belong to the effective area indicated by the area information, the terminal device may delete the first configuration information corresponding to the first serving cell. In this embodiment of the present application, the first configuration information corresponding to the first serving cell is the first configuration information determined in step S701. Optionally, the terminal device can perform some or all of the steps similar to the above steps S701-S703a, or S701-S703b, or S701-S704. The difference is that the serving cell of the terminal device is the second serving cell, and the network device is the second serving cell. The network device to which the cell belongs. For example, if the system message of the second serving cell contains the public measurement configuration information corresponding to the second serving cell, the terminal device can determine the corresponding measurement configuration information of the second serving cell according to the public measurement configuration information of the second serving cell. For the first configuration information, you can continue to perform some or all of the steps similar to steps S702-S703a, or S702-S703b, or S702-S704. It can be understood that the first configuration information corresponding to the second serving cell and the first configuration information corresponding to the first serving cell may be the same or different.

In the case that the second serving cell belongs to the effective area indicated by the area information, the terminal device may determine the first configuration information corresponding to the second serving cell. Optionally, the terminal device may determine the first configuration information corresponding to the second serving cell according to the common measurement configuration information of the second serving cell; or the terminal device may determine the first configuration information corresponding to the second serving cell according to the common measurement configuration information of the second serving cell and the terminal device from the second serving cell. The dedicated measurement configuration information received by a serving cell determines the first configuration information corresponding to the second serving cell. The subsequent terminal device may continue to perform some or all of the steps similar to steps S702-S703a, or S702-S703b, or S702-S704.

Optionally, if the terminal device has available or valid measurement result information related to the first measurement, the terminal device may send a first measurement report related to the first measurement to the network device to which the second serving cell belongs, that is, perform similar Step in step S702. It can be understood that the first network device corresponding to the first serving cell and the second network device corresponding to the second serving cell may be the same network device or different network devices.

Optionally, the available or valid measurement result information related to the first measurement may be the available or valid first cell measurement result information recorded when the terminal device is located in the first serving cell, and/or the terminal device Available or valid measurement result information of the first cell recorded when located in the second serving cell.

It can be understood that the first cell measured by the terminal device in the first serving cell and the first cell measured by the terminal device in the second serving cell may be the same cell or different cells.

Optionally, the first measurement report related to the first measurement sent by the terminal device to the network device to which the second serving cell belongs may include part or all of the available or valid first cell recorded by the terminal device in the first serving cell The measurement result information of the first cell, and/or part or all of the available or valid measurement result information of the first cell recorded by the terminal device in the second serving cell. In other words, the first measurement report related to the first measurement sent by the terminal device to the network device to which the second serving cell belongs may include the first measurement report obtained by the terminal device performing the first measurement in the first serving cell (referred to as the first measurement report). The first measurement report corresponding to a serving cell), and/or the first measurement report obtained by the terminal device performing the first measurement in the second serving cell (referred to as the first measurement report corresponding to the second serving cell).

For example, if the terminal device performs the first measurement in the first serving cell, but does not perform the first measurement in the second serving cell, the terminal device may send the first measurement corresponding to the first serving cell to the network device to which the second serving cell belongs report. For example, the terminal device may determine the first measurement report corresponding to the first serving cell according to the available or valid measurement result information of the first cell recorded by the terminal device in the first serving cell. In other words, the terminal device sends the neighboring cell information of the first serving cell to the network device to which the second serving cell belongs.

For another example, if the terminal device performs the first measurement in the first serving cell and the second serving cell respectively, the terminal device may send the available or valid records recorded by the terminal device in the first serving cell to the network device to which the second serving cell belongs. The measurement result information of the first cell, and/or the available or valid measurement result information of the first cell recorded in the second serving cell. In other words, the terminal device sends the neighboring cell information of the first serving cell and/or the second serving cell to the network device to which the second serving cell belongs.

For another example, if the terminal device does not perform the first measurement in the first serving cell or the terminal device does not record available or valid measurement result information of the first cell in the first serving cell, but performs the first measurement in the second serving cell , The terminal device may send the first measurement report corresponding to the second serving cell to the network device to which the second serving cell belongs. For example, the terminal device may determine the first measurement report corresponding to the second serving cell according to the available or valid measurement result information of the first cell recorded by the terminal device in the second serving cell. In other words, the terminal device sends the neighboring cell information of the second serving cell to the network device to which the second serving cell belongs.

Optionally, after receiving the first measurement report related to the first measurement, the network device to which the second serving cell belongs may determine whether the first cell included in the first measurement report includes a neighboring cell of the second serving cell. In the case that the first cell includes the neighboring cell of the second serving cell, the network device to which the second serving cell belongs can optimize the capacity and coverage according to the neighboring cell information of the second serving cell. When the capacity of the network device drops, the terminal device is handed over to a neighboring cell with better quality of the second serving cell.

The following describes the relevant implementation of the terminal device determining the first configuration information in the foregoing step S701.

Based on the embodiment shown in FIG. 7, as shown in FIG. 8, before step S701, the measurement method provided in the embodiment of the present application further includes:

S700a. The network device determines the first information.

The first information is used for the terminal device to determine the first configuration information, and the first configuration information is used for configuring the terminal device in the RRC disconnected state to perform the first measurement when the measurement result of the serving cell is less than or equal to the first threshold .

It is understandable that the network device may be the network device to which the serving cell (ie, the first serving cell) of the terminal device in the above step S701 belongs. Correspondingly, this step S700a-the first configuration information in the following step S700b refers to The first configuration information corresponding to the first serving cell; or, the network device may be a network device to which the second serving cell belongs. Correspondingly, this step S700a-the first configuration information in the following step S700b refers to the second serving cell The first configuration information.

Optionally, the first information may be dedicated measurement configuration information and/or public measurement configuration information, and the dedicated measurement configuration information and/or public measurement configuration information may be used to configure the terminal device in the RRC disconnected state to perform the first One measurement.

It is understandable that the dedicated measurement configuration information may be measurement configuration information for a certain terminal device to be used alone. The dedicated measurement configuration information can be sent to the terminal device through a dedicated message, such as an RRC message. The dedicated measurement configuration information of different terminal devices may be different or the same. The common measurement configuration information may be measurement configuration information used by multiple terminal devices. The common measurement configuration can be sent to the terminal device through broadcast or multicast messages, such as system messages or multicast service messages. Different terminal devices can use the common measurement configuration information together.

Based on this solution, when the first information is dedicated measurement configuration information, different measurement parameters can be configured for different terminal devices to improve measurement flexibility; when the first information is common measurement configuration information, there is no need to provide each terminal The device sends the common measurement configuration information separately, which can reduce signaling overhead; when the first information is dedicated measurement configuration information and public measurement configuration information, it may not be necessary to configure all measurement parameters in the dedicated measurement configuration information, that is, Part of the measurement parameters are sent to the terminal device in the dedicated measurement configuration information, and the terminal device can obtain the measurement parameters that are not sent in the dedicated measurement configuration information from the public measurement configuration information. Through this scheme, the transmission overhead can be reduced while improving flexibility.

S700b. The network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

Optionally, when the first information includes common measurement configuration information, the network device may send the common measurement configuration information in a system message or a multicast message. Correspondingly, the terminal device can receive the system message or the multicast message, and obtain the common measurement configuration information included in the system message or the multicast message.

Optionally, in the case that the first information includes dedicated measurement configuration information, the network device can use an RRC resume message, an RRC reconfiguration message, and an RRC establishment when the terminal device is in the RRC connection state. One of the (RRC setup) message and the RRC release (RRC release) message sends the dedicated measurement configuration information to the terminal device.

Optionally, in the case where the first information includes dedicated measurement configuration information, before step S700b, the measurement method may further include, for example, the network device acquiring capability indication information of the terminal device. Wherein, the capability indication information of the terminal device may indicate whether the terminal device supports the first measurement.

Optionally, acquiring the capability indication information of the terminal device by the network device may include: the network device receives the capability indication information of the terminal device from the terminal device. In this case, the method in this embodiment of the present application may also include: Sending capability indication information; or, the network device receives the capability indication information of the terminal device from the core network device; or the network device receives the capability indication information of the terminal device from other network devices other than the network device, exemplary , Other network devices can be network devices that the terminal device has accessed before. In the embodiment of the present application, description is made by taking the capability indication information of the terminal device indicating that the terminal device supports the first measurement as an example.

Optionally, before the network device receives the capability indication information of the terminal device, the network device may request the terminal device or the core network device or other network equipment for the capability indication information of the terminal device.

In this scenario, in step S700b, the network device sending the first information to the terminal device may include: sending the first information to the terminal device when the capability indication information of the terminal device indicates that the terminal device supports the first measurement .

Based on this solution, when the terminal device supports the first measurement, the network device sends the first information to the terminal device, which can avoid the resources brought by the network device sending the first information when the terminal device does not support the first measurement. Waste.

Based on steps S700a-S700b, in step S701, the terminal device may determine the first configuration information according to the first information, that is, the terminal device may determine the first configuration information according to the dedicated measurement configuration information and/or the public measurement configuration information.

Optionally, in the case where the first configuration information includes the first threshold, the measurement configuration information included in the first information may be different, and accordingly, the manner in which the terminal device determines the first threshold may also be different:

In a possible implementation manner, the first information includes only dedicated measurement configuration information, and the dedicated measurement configuration information includes threshold 1. Accordingly, the terminal device may determine the threshold 1 as the first threshold.

In another possible implementation manner, the first information includes only common measurement configuration information, and the common measurement configuration information includes threshold 2. Accordingly, the terminal device may determine the first threshold with the threshold 2.

In another possible implementation manner, the first information includes public measurement configuration information and dedicated measurement configuration information. The public measurement configuration information may include a reference threshold, and the dedicated measurement configuration information may include a threshold offset. Accordingly, the terminal device may determine the first threshold according to the dedicated measurement configuration information and the public measurement configuration information. Exemplarily, the terminal device may determine the first threshold as the sum of the reference threshold and the threshold offset, or may determine the first threshold as the difference between the reference threshold and the threshold offset.

In yet another possible implementation manner, the first information includes public measurement configuration information and dedicated measurement configuration information, and the dedicated measurement configuration information includes threshold 1, and the public measurement configuration information includes threshold 2, and correspondingly, the terminal device Threshold 1 may be used to determine the first threshold, that is, the first threshold configured by the dedicated measurement configuration information of the terminal device shall prevail. Optionally, threshold 1 and threshold 2 may be different or the same.

Optionally, in the case where the first configuration information includes multiple measurement parameters including the first threshold, in the foregoing step S701, the terminal device determining the first configuration information may include: when the first information includes only the common measurement configuration In the case of information, the terminal device determines the first configuration information according to the public measurement configuration information; or, in the case where the first information includes only dedicated measurement configuration information, the terminal device determines the first configuration information according to the dedicated measurement configuration information; Or, in a case where the first information includes dedicated measurement configuration information and public measurement configuration information, the terminal device determines the first configuration information according to the dedicated measurement configuration information and the public measurement configuration information.

Optionally, in a case where the first information includes dedicated measurement configuration information and public measurement configuration information, in a possible implementation manner, if the dedicated measurement configuration information includes all parameters necessary to perform the first measurement, the terminal The device may only determine the first configuration information based on the dedicated measurement configuration information; if the dedicated measurement configuration information includes some parameters necessary to perform the first measurement, the terminal device may determine the first measurement based on the dedicated measurement configuration information. The first configuration information is determined according to a part of the parameters of and according to another part of the parameters necessary to perform the first measurement included in the common measurement configuration information. Exemplarily, in addition to the first threshold, the parameters necessary to perform the first measurement include measurement target configuration information and the second threshold as an example. If the dedicated measurement configuration information includes measurement target configuration information, the public measurement configuration information includes the measurement target. Configuration information and the second threshold, the first configuration information determined by the terminal device includes the measurement target configuration information included in the dedicated measurement configuration information and the second threshold included in the public measurement configuration information.

Based on this solution, a method for the terminal device to determine the first configuration information under different first information can be provided, and the behavior of the terminal device can be regulated, so that the terminal device can perform measurements better in the future.

In addition, in an implementation scenario of the embodiment of the present application, the network device may be a CU. In the embodiment of the present application, the method and/or steps implemented by the network device may be implemented by the CU; or, the network device may be the DU. , Then in the embodiments of the present application, the methods and/or steps implemented by the network equipment may be implemented by DU; or, the network equipment may be composed of CU and DU, then in the embodiments of the present application, the methods and/or steps implemented by the network equipment Or steps can be implemented by CU and/or DU.

Exemplarily, when the network device is a CU, the CU may determine the first information in step S700a; when the network device is a DU, the DU may determine the first information in step S700a; when the network device is composed of CU and DU, in step S700a The first information may be determined by the DU, or the first information may be determined by the CU, which is not specifically limited in the embodiment of the present application.

In a possible implementation manner, when the DU determines the first information in step S700a, optionally, the DU may send the first information to the CU. Optionally, before the DU sends the first information to the CU, the CU may request the first information from the DU.

Optionally, the DU may carry the first information in an F1 establishment request message or a gNB-DU configuration update message, or a gNB-CU configuration update confirmation message and send it to the CU.

In another possible implementation manner, when the CU determines the first information in step S700a, optionally, the CU may send the first information to the DU. Optionally, before the CU sends the first information to the DU, the DU may request the first information from the CU.

Optionally, the CU may carry the first information in the F1 establishment response message, or the gNB-CU configuration update message, or the gNB-DU configuration update confirmation message and send it to the DU.
