Background

With the development of communication technology, communication operators have begun the construction of fifth generation (5g) networks. Currently, 5G networks usually use a Non Stand Alone (NSA) networking mode and a Stand Alone (SA) mode.

In the prior art, after a connected 5G terminal device moves from a 4G network to a coverage area of the 5G network, a network device may issue a B1 measurement event to the 5G terminal device. The B1 measurement event may be used to instruct the 5G terminal device to measure the signal quality of the 5G network. If the 5G terminal device does not measure the signal of the 5G network, the network device will periodically issue a B1 measurement event to the 5G terminal device. The 5G terminal device will also periodically perform gap (gap) measurements. The periodic gap measurement of the 5G terminal device increases the power consumption of the 5G terminal device.

Fig. 3 provides a measurement method for an embodiment of the present application, and as shown in fig. 3, the method includes:

step 301, the network device determines whether the terminal device meets the trigger condition.

The network device may be any network device in fig. 1, for example, the network device 1 or the network device 2, which is not limited. The terminal device may be any terminal device in fig. 1, for example, UE1 or UE2, without limitation.

The triggering condition may be that the current communication state of the terminal device meets a preset condition. For example, the triggering condition may include that the terminal device performs cell handover, the terminal device does not perform cell handover, but a Timing Advance (TA) of the terminal device meets a preset value.

The trigger condition is explained below.

1. The terminal equipment undergoes cell handover.

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

The network device may determine that the terminal device performs cell handover according to a connection request (e.g., a Radio Resource Control (RRC) connection request) sent by the terminal device. That is, when the terminal device moves from the a cell to the B cell, it needs to send an RRC connection request to the network device of the B cell. After receiving the RRC connection request of the terminal device, the network device determines that the terminal device has cell handover.

2. The terminal equipment does not have cell switching and the TA of the terminal equipment meets the preset value.

The non-occurrence of cell handover in the terminal device may mean that the terminal device and the network device maintain communication connection, or that the RRC connection between the terminal device and the network device is not interrupted.

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 one example, the terminal device may periodically send a TA to the network device. For example, the TA is included/carried in a protocol in a Measurement Report (MR) sent by the terminal device to the network device. After receiving the TA sent by the terminal device, the network device may determine whether the TA of the terminal device meets a preset value according to the TA of the terminal device in the current period and the TA before the terminal device.

For example, if the TA of the current period of the terminal device (referred to as a first TA for short) is greater than the TA of one period before the current period of the terminal device (referred to as a second TA for short), the network device may determine that the TA of the terminal device satisfies 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 satisfy 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 equipment receives the first indication information from the network equipment.

The first indication information may be used to instruct the terminal device to measure the first network. For example, the first indication information may be an inter-system B1 measurement event. The inter-system B1 measurement event can refer to the prior art, and is not described in detail. The first network may be a higher priority network of the location where the terminal device is located. For example, if the terminal device moves from a 4G network to a 5G network coverage area, the first network may be a 5G network.

In one example, if the network device determines that the terminal device has performed cell handover, the network device may send first indication information to the terminal device.

In another example, if the network device determines that the terminal device does not perform cell handover, 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 scheme of fig. 3, the network device determines whether the terminal meets the trigger condition, and under the condition that the terminal meets the trigger condition, the network device issues the indication information, so that the terminal measures the neighboring cell. Compared with the prior art, the terminal equipment does not need to carry out periodic measurement all the time, so that the measurement times can be reduced, and the power consumption of the terminal equipment can be reduced.

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

step 401, the terminal device measures the first network.

The measurement performed by the terminal device on the first network may refer to the terminal device measuring the network quality of the first network. For example, it may be a gap measurement.

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

The preset threshold may include a preset value corresponding to a signal quality parameter of the first network. The signal quality parameters may include Reference Signal Receiving Power (RSRP), 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 step 403 described below.

In one example, the terminal device may access the first network if the signal quality of the first network is greater than a preset value, for example, RSRP of the first network is greater than a first threshold, and/or SINR is greater than a second threshold. The first threshold and the second threshold may be set as needed, and are not limited.

In another example, in a case where the first indication information is a B1 measurement event, the terminal device may determine whether the first network satisfies the B1 event. The B1 event may refer to the prior art, and is not 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. Accordingly, 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 for the signal quality of the first network. For another example, the first response message may include a B1 event measurement. For another example, the first response message may include an MR of the first network.

If the terminal device determines that the first network meets the B1 event, the terminal device can 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, to avoid that the terminal device affects the use of the user under the condition that the terminal device does not access 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.

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

In one 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.

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. And if the signal quality parameter is less than the threshold, the signal quality of the first network does not meet the access condition.

Based on the technical scheme of fig. 4, the network device may determine that the terminal device accesses the first network according to the response message of 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 of the terminal device, the network device may resend the first indication information to the terminal device, so that the terminal device can measure the first network again.

The method provided by the embodiment of the present application is described below with reference to specific scenarios.

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

If the NSA terminal equipment moves from the 4D network scene to the NSA networking scene and meets the same-frequency switching condition, the NSA terminal equipment is switched from the 4G network of the cell A to the 4G network of the cell B. After the NSA terminal device accesses the 4G network of the cell B, the cell B may be triggered to issue an NSA B1 measurement event to the NSA terminal device. The NSA terminal device measures signal quality of a cell B and NR cells around the cell B. If the NR cell meets the B1 event, the NSA terminal equipment reports an NSA B1 MR and executes an NR cell adding process.

And in the scenario 2, the terminal equipment does not have cell switching and enters an NSA networking scenario from the 4G network.

If the NSA terminal equipment does not have cell switching and enters the NSA networking scene from the 4G network, the TA reported by the NSA terminal equipment in the current period is 7, and the TA reported in the previous period is 6. That is, the terminal device meets the trigger condition, and may trigger the network device to issue the NSA B1 measurement event to the NSA terminal device. The NSA terminal device measures the signal quality of the surrounding NR cells. And if the signal quality of the surrounding NR cells meets the B1 event, the NSA terminal equipment reports the MSA B1 MR to the network equipment and executes an NR cell adding process.

Scene 3, the terminal device moves from the 4G network to the SA networking scene.

If the SA terminal equipment moves from the 4G network to the SA networking scene and meets the same-frequency switching condition, the SA terminal equipment is switched from the 4G network of the cell A to the 4G network of the cell B. After the SA terminal device accesses the 4G network of the cell B, the cell B may be triggered to issue an SA B1 measurement event to the SA terminal device. The SA terminal device measures the signal quality of the surrounding NR cells. If the surrounding NR cells meet the B1 event, the SA terminal equipment reports an SA B1 MR to the cell B and executes the interoperation process from the 4G network to the 5G network (namely, accesses the 5G network).

And in the scenario 4, the terminal equipment does not have cell switching and enters an SA networking scenario from the 4G network.

And if the SA terminal does not have cell switching, entering an SA networking scene from the 4G network. The TA reported by the SA terminal device in the current cycle is 7, and the TA reported in the previous cycle is 6. That is, the SA terminal device satisfies the trigger condition, and the network device may issue the SA B1 measurement event to the SA terminal device. The SA terminal device can measure the signal quality of the surrounding NR cells after receiving the SA B1 measurement event. If the surrounding NA cell satisfies the B1 event, the SA terminal device may report the SA B1 MR to the network device, and execute the 4G to 5G interoperation process.
