Fig. 3 provides a kind of measuring method for the embodiment of the present application, as shown in Fig. 3, this method comprises:

Step 301, the network device judges whether the terminal device satisfies the trigger condition.

Wherein, the network device may be any network device in FIG. 1 , for example, it may be network device 1 or network device 2, without limitation. The terminal device may be any terminal device in FIG. 1 , for example, UE1 or UE2, without limitation.

Wherein, the trigger condition may be that the current communication state of the terminal device satisfies a preset condition. For example, the trigger condition may include that the terminal device undergoes cell handover, and the terminal device does not undergo cell handover but the timing advance (timing advance, TA) of the terminal device satisfies a preset value.

The trigger conditions are described below.

1. The terminal device undergoes cell handover.

The cell handover of the terminal device may refer to the movement of the terminal device from one cell to another cell. For example, as shown in Figure 1, a terminal device moves from cell 2.1 to cell 1.1.

Wherein, the network device may determine that the terminal device has undergone a cell handover according to a connection request (such as a radio resource control (radioresource control, RRC) connection request) sent by the terminal device. That is, when the terminal device moves from cell A to cell B, it needs to send an RRC connection request to the network device of cell B. After receiving the RRC connection request from the terminal device, the network device determines that cell handover has occurred in the terminal device.

2. The terminal device does not undergo cell handover and the TA of the terminal device meets the preset value.

Wherein, the fact that the terminal device does not undergo cell switching may refer to that the terminal device maintains a communication connection with the network device, or that the RRC connection between the terminal device and the network device is not interrupted.

Wherein, the TA of the terminal device meeting the preset value may mean that the current TA of the terminal device is greater than the previous TA value.

In an example, the terminal device may periodically send the TA to the network device. For example, the protocol in the measurement report (measurement report, MR) sent by the terminal device to the network device includes/carries the TA. After receiving the TA sent by the terminal device, the network device can judge whether the TA of the terminal device satisfies the preset value according to the current periodic TA of the terminal device and the previous TA of the terminal device.

For example, if the TA of the current period of the terminal device (referred to as the first TA for short) is greater than the TA of one period before the current period of the terminal device (referred to as the second TA for short), the network device may determine that the TA of the terminal device meets the preset value. If the first TA of the terminal device is less than or equal to the second TA of the terminal device, the network device may determine that the TA of the terminal device does not meet the preset value.

Step 302: If the terminal device meets the trigger condition, the network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device.

Wherein, the first indication information may be used to instruct the terminal device to perform measurement on the first network. For example, the first indication information may be a measurement event of the foreign system B1. For the measurement event of the different system B1, reference may be made to the prior art, and details are not repeated here. The first network may be a network with higher priority where the terminal device is located. For example, if the terminal device moves from the 4G network to the coverage area of the 5G network, the first network may be the 5G network.

In an example, if the network device determines that a cell switch has occurred on the terminal device, the network device may send the first indication information to the terminal device.

In another example, if the network device determines that the terminal device does not undergo cell switching, and the first TA of the terminal device is greater than the second TA, the network device may send the first indication information to the terminal device.

Based on the technical solution in FIG. 3 , the network device judges whether the terminal meets the trigger condition, and if the terminal device meets the trigger condition, the network device sends instruction information so that the terminal can measure neighboring cells. Compared with the prior art, the terminal device does not need to perform periodic measurement all the time, so the number of measurements can be reduced, and the terminal device can reduce power consumption.

In a possible implementation manner, as shown in FIG. 4 in combination with the technical solution in FIG. 3 , the method provided in the embodiment of the present application may further include:

Step 401, the terminal device measures the first network.

Wherein, the terminal device measuring the first network may refer to the terminal device measuring the network quality of the first network. For example, gap measurement can be used.

Step 402, the terminal device judges whether the network quality of the first network meets a preset threshold.

Wherein, the preset threshold may include a preset value corresponding to a signal quality parameter of the first network. The signal quality parameter may include a reference signal receiving power (reference signal receiving power, RSRP), a signal to interference plus noise ratio (signal to interference plus noise ratio, SINR), and the like.

If the terminal device meets the preset threshold, the terminal device can access the first network. The terminal device may perform the following step 403 .

In an example, if the signal quality of the first network is greater than a preset value, for example, the RSRP of the first network is greater than a first threshold, and/or the SINR is greater than a second threshold, the terminal device may access the first network. Wherein, the first threshold and the second threshold can be set as required without limitation.

In another example, when the first indication information is a B1 measurement event, the terminal device may determine whether the first network meets the B1 event. Wherein, the B1 event can refer to the prior art, and will not be described in detail.

Step 403: If the network quality of the first network meets the preset threshold, the terminal device sends a first response message to the network device. Correspondingly, the network device receives the first response message from the terminal device.

Wherein, the first response message may be used to indicate that the terminal device has accessed the first network. For example, the first response message may include a plurality of parameter values of the signal quality of the first network. For another example, the first response message may include the B1 event measurement result. For another example, the first response message may include the MR of the first network.

If the terminal device determines that the first network satisfies the B1 event, the terminal device may send a first response message to the network device after accessing the first network.

If the terminal device determines that the first network does not satisfy the B1 event or the terminal device cannot access the first network, the terminal device may not send the first response message to the network device.

In another possible implementation manner, in order to prevent the terminal device from affecting the use of the user when the terminal device is not connected to the first network, as shown in FIG. 4 , the method provided in the embodiment of the present application may further include:

Step 404: If the network device does not receive the first response message, the network device resends the first indication information to the terminal device.

Wherein, the fact that the network device does not receive the first response message may refer to that the network device does not receive the first response message within a preset time. Or, the network device determines that the signal quality of the first network does not meet the access condition. Wherein, the access condition may refer to that the signal quality of the first network is lower than a threshold. The preset time can be set as required, and will not be described in detail.

In an example, the first response message may include a cell identifier corresponding to the first network, a signal quality parameter of the first network, a coverage area of the first network, and the like.

Wherein, the network device may determine the signal quality of the first network according to the signal quality parameter in the MR reported by the terminal device. If the signal quality parameter is smaller than the threshold, it indicates that the signal quality of the first network does not meet the access condition.

Based on the technical solution in FIG. 4 , the network device can determine that the terminal device accesses the first network according to the response message from the terminal device, thereby ensuring normal communication between the terminal device and the network device. If the network device does not receive the response message from the terminal device, the network device may resend the first indication information to the terminal device, so that the terminal device performs measurement on the first network again.

The method provided in the embodiment of the present application will be described below in combination with specific scenarios.

Scenario 1. The terminal device moves from the 4G network to the NSA networking scenario.

If the NSA terminal device moves from the 4D network scenario to the NSA networking scenario and meets the same-frequency handover conditions, the NSA terminal device switches from the 4G network of cell A to the 4G network of cell B. After the NSA terminal device accesses the 4G network of cell B, it can trigger cell B to deliver the NSA B1 measurement event to the NSA terminal device. The NSA terminal equipment measures the signal quality of the cell B and the NR cells around the cell B. If the NR cell meets the B1 event, the NSA terminal device reports the NSA B1 MR and executes the NR cell addition process.

Scenario 2: The terminal device does not undergo cell handover, and enters the NSA networking scenario from the 4G network.

If the NSA terminal device does not undergo cell handover and enters the NSA networking scenario from the 4G network, the TA reported by the NSA terminal device in the current cycle is 7, and the TA reported in the previous cycle is 6. That is, when the terminal device satisfies the trigger condition, the network device may be triggered to deliver the NSA B1 measurement event to the NSA terminal device. The NSA terminal device measures the signal quality of surrounding NR cells. If the signal quality of the surrounding NR cells meets the B1 event, the NSA terminal device reports the MSA B1 MR to the network device, and executes the NR cell addition process.

Scenario 3. The terminal device moves from the 4G network to the SA networking scenario.

If the SA terminal device moves from the 4G network to the SA networking scenario and the same-frequency handover condition is met, the SA terminal device switches from the 4G network of cell A to the 4G network of cell B. After the SA terminal device accesses the 4G network of cell B, it can trigger cell B to deliver the SA B1 measurement event to the SA terminal device. The SA terminal device measures the signal quality of surrounding NR cells. If the surrounding NR cells meet the B1 event, the SA terminal device reports the SA B1 MR to the cell B, and executes the interoperability process from the 4G network to the 5G network (that is, accesses the 5G network).

Scenario 4: The terminal device does not undergo cell handover, and enters the SA networking scenario from the 4G network.

If the SA terminal does not undergo cell handover, and enters the SA networking scene from the 4G network. The TA reported by the SA terminal device in the current period is 7, and the TA reported in the previous period is 6. That is, the SA terminal device meets the trigger condition, and the network device can deliver the SA B1 measurement event to the SA terminal device. After receiving the SA B1 measurement event, the SA terminal device can measure the signal quality of the surrounding NR cells. If the surrounding NA cells meet the B1 event, the SA terminal device can report the SA B1 MR to the network device, and execute the interoperability process from 4G to 5G.
