Some terms in this application are explained below:

a main node and a secondary node: in MR-DC scenarios, the terminal device is connected to both the primary and secondary nodes. The main node is a main base station connected with the terminal equipment, and the auxiliary node is an auxiliary base station connected with the terminal equipment.

Measurement interval configuration: when the main node or the auxiliary node has the requirement of enabling the terminal equipment to carry out different-frequency or different-system measurement, the main node transmits measurement information, wherein the information comprises measurement interval configuration, specifically, the measurement interval configuration can comprise one or more of measurement interval repetition periods, measurement interval lengths and bias of measurement interval patterns in the measurement interval repetition periods, optionally, the measurement interval configuration can also comprise taking the frame number/subframe number of which cell or node as a reference when the measurement interval is calculated, and the terminal equipment can calculate the corresponding measurement interval based on the measurement interval configuration and execute the different-frequency or different-system measurement in the measurement interval. Since the terminal device may need to switch the radio frequency module when performing inter-frequency or inter-system measurements, the protocol defines that the primary node and the secondary node do not schedule the terminal device within the measurement interval.

In order to solve the above technical problem, fig. 2 is a flowchart of an embodiment one of a measurement interval configuration method provided in the present application, where in this embodiment, an auxiliary node connected to a terminal device after an auxiliary node is changed is referred to as a first auxiliary node, and an auxiliary node connected to a terminal device before an auxiliary node is changed is referred to as a second auxiliary node. As shown in fig. 2, the method for configuring a measurement interval provided in this embodiment includes:

s201, the master node obtains measurement interval configuration of the terminal equipment before the auxiliary node changes.

S202, the master node sends measurement interval configuration and first indication information to the first auxiliary node.

When the node needs to make the terminal device perform different frequency or different system measurement, the node triggers the generation of measurement interval configuration of the terminal device. The measurement interval configuration of the terminal device before the secondary node change, which is acquired by the primary node in S201, may be triggered by the primary node, or may be triggered by the second secondary node, or may be triggered by both the primary node and the second secondary node.

If the measurement interval configuration mentioned in S201 is triggered by the second secondary node, as described in S202, the primary node may simultaneously transmit, when transmitting the measurement interval configuration to the first secondary node, first indication information for querying whether the measurement interval configuration is valid. The first indication information is used to query whether the measurement interval configuration is valid, it may be understood that the first indication information is used to query whether the first secondary node takes effect of the measurement interval configuration, or to query whether the first secondary node accepts the measurement interval configuration, or to query whether the first secondary node needs the measurement interval configuration, etc., which is not limited in this embodiment of the present application.

The procedure for triggering the generation of the measurement interval configuration by the second secondary node is described as follows:

when the second auxiliary node has the requirement of enabling the terminal equipment to conduct different-frequency or different-system measurement, the requirement is sent to the main node, after the main node receives the requirement, measurement interval configuration is generated and sent to the second auxiliary node, the second auxiliary node further sends the measurement interval configuration to the terminal equipment, or the main node sends the measurement interval configuration to the terminal equipment, and as the main node and the second auxiliary node are both provided with the measurement interval configuration, the main node and the second auxiliary node have consistent understanding on the measurement interval, so that when the terminal equipment conducts different-frequency or different-system measurement in the measurement interval, the main node and the second auxiliary node do not schedule the terminal equipment, and packet loss is avoided.

S203, the first auxiliary node determines whether the measurement interval configuration is effective according to the first indication information.

In a possible implementation manner, the first auxiliary node judges whether the first auxiliary node has the requirement of enabling the terminal equipment to perform different-frequency or different-system measurement, if so, the received measurement interval configuration is determined to be effective, and as the first auxiliary node and the main node are both provided with the measurement interval configuration, the main node and the first auxiliary node have consistent understanding on the measurement interval, so that when the terminal equipment performs different-frequency or different-system measurement in the measurement interval, the main node and the first auxiliary node can not schedule the terminal equipment, and packet loss is avoided; if the measurement interval configuration is not available, it is determined that the received measurement interval configuration is invalid, and as a result, the first auxiliary node has a space for judging due to the setting of the first indication message, and compared with a mode that the primary node only sends the measurement interval configuration to the first auxiliary node, and the first auxiliary node directly takes effect of the measurement interval configuration, the method of the embodiment can avoid resource waste caused by stopping scheduling of the terminal device in the measurement interval when the first auxiliary node does not have the requirement of making the terminal device perform different-frequency or different-system measurement.

S204, the first auxiliary node sends a second indication message to the main node.

Specifically, if the first auxiliary node determines that the measurement interval configuration is valid, the second indication information is used to indicate that the measurement interval configuration is valid, or is used to indicate that the first auxiliary node will take effect of the measurement interval configuration, or is used to indicate that the first auxiliary node accepts the measurement interval configuration, or is used to indicate that the first auxiliary node needs the measurement interval configuration. If the first auxiliary node determines that the measurement interval configuration is invalid, the second indication information is used for indicating that the measurement interval configuration is invalid, or is used for indicating that the first auxiliary node will not take effect on the measurement interval configuration, or is used for indicating that the first auxiliary node does not accept the measurement interval configuration, or is used for indicating that the first auxiliary node does not need the measurement interval configuration.

In one possible implementation, the second indication information may be a cell, where a value of 1 indicates that the measurement interval configuration is valid, and a value of 0 indicates that the measurement interval configuration is not valid.

According to the configuration method of the measurement interval, after the auxiliary node connected with the terminal equipment is changed from the second auxiliary node to the first auxiliary node, the main node sends the measurement interval configuration of the terminal equipment before the auxiliary node is changed and the first indication information to the first auxiliary node, and when the first auxiliary node needs to enable the terminal equipment to conduct different frequency or different system measurement, the measurement interval configuration is validated, so that the main node and the first auxiliary node can understand the measurement interval consistently, packet loss is avoided, and in addition, compared with the mode that the first auxiliary node requests the main node to reconfigure the measurement interval again, signaling cost and time delay are saved. When the first auxiliary node does not have the requirement of enabling the terminal equipment to conduct different-frequency or different-system measurement, the measurement interval configuration is not validated, and resource waste caused by stopping scheduling of the terminal equipment in the measurement interval can be avoided when the first auxiliary node does not have the requirement of enabling the terminal equipment to conduct different-frequency or different-system measurement.

Fig. 3 is a flow chart of a second embodiment of a measurement interval configuration method provided in the present application, and in this embodiment, similarly to the foregoing embodiment, an auxiliary node connected to a terminal device after an auxiliary node is changed is referred to as a first auxiliary node, and an auxiliary node connected to a terminal device before an auxiliary node is changed is referred to as a second auxiliary node. As shown in fig. 3, the method for configuring a measurement interval provided in this embodiment includes:

s301, a master node acquires measurement interval configuration of a terminal device before the change of an auxiliary node and information of a trigger node indicating the measurement interval configuration.

S302, the primary node sends measurement interval configuration and information indicating a trigger node of the measurement interval configuration to the first secondary node.

Referring to the description of S202 in the above embodiment, the measurement interval configuration may be triggered by the primary node, or may be triggered by the second secondary node, or may be triggered by both the primary node and the second secondary node. The above information indicating the trigger node of the measurement interval configuration may be used to indicate whether the trigger node is a primary node, a secondary node, or both.

The process of triggering the generation of the measurement interval configuration by the second auxiliary node is referred to S202 in the above embodiment, which is not described herein.

The procedure for generating measurement interval configuration triggered by the master node is described as follows:

when the main node has the requirement of enabling the terminal equipment to carry out different-frequency or different-system measurement, the measurement interval configuration is generated and sent to the second auxiliary node and the terminal equipment, and as the main node and the second auxiliary node are both provided with the measurement interval configuration, the main node and the second auxiliary node have consistent understanding on the measurement interval, so that when the terminal equipment carries out different-frequency or different-system measurement in the measurement interval, the main node and the second auxiliary node can not schedule the terminal equipment, thereby avoiding packet loss.

The process of the primary node and the second secondary node triggering the generation of the measurement interval configuration together is described as follows:

when the second auxiliary node has the requirement for the terminal equipment to perform different-frequency or different-system measurement, the requirement is sent to the main node, the main node generates measurement interval configuration according to the requirement and the requirement of the main node, and sends the measurement interval configuration to the second auxiliary node and the terminal equipment.

S303, the first auxiliary node determines whether the measurement interval configuration is effective according to the information of the trigger node indicating the measurement interval configuration.

Since the method provided in this embodiment is provided in the scenario where the secondary node connected to the terminal device changes, where the primary node connected to the terminal device is default to not change, if the measurement interval configuration is triggered by the primary node, or the primary node and the second secondary node are triggered together, the measurement interval configuration is applicable to the first secondary node, then S303 may be implemented as follows:

if the information of the trigger node indicating the measurement interval configuration indicates that the trigger node is the master node, determining that the measurement interval configuration is valid, and if the information of the trigger node indicating the measurement interval configuration indicates that the trigger node includes the master node and the second auxiliary node, determining that the measurement interval configuration is valid. Because the first auxiliary node and the main node are both provided with the measurement interval configuration, the main node and the first auxiliary node have consistent understanding on the measurement interval, so that when the terminal equipment performs different frequency or different system measurement in the measurement interval, the main node and the first auxiliary node can not schedule the terminal equipment, and packet loss is avoided. If the information of the trigger node indicating the measurement interval configuration indicates that the trigger node is a second auxiliary node, further judging whether the first auxiliary node has the requirement of enabling the terminal equipment to perform different frequency or different system measurement, and if so, determining that the measurement interval configuration is effective; if not, the measurement interval configuration is determined to be invalid. As can be seen, the information indicating the trigger node of the measurement interval configuration, which is sent by the master node to the first auxiliary node, makes the first auxiliary node have a space for judging, and compared with the mode that the master node only sends the measurement interval configuration to the first auxiliary node, and the first auxiliary node directly takes effect of the measurement interval configuration, the method of the embodiment can avoid resource waste caused by stopping scheduling of the terminal device in the measurement interval when the first auxiliary node does not have the requirement of making the terminal device perform inter-frequency or inter-system measurement.

S304, the first auxiliary node sends a second indication message to the main node.

According to the configuration method of the measurement interval, after the auxiliary node connected with the terminal equipment is changed from the second auxiliary node to the first auxiliary node, the main node sends measurement interval configuration and information indicating a trigger node of the measurement interval configuration to the first auxiliary node. If the trigger node is the master node or the master node and the second auxiliary node, the first auxiliary node takes effect of the measurement interval configuration, so that the master node and the first auxiliary node have consistent understanding on the measurement interval, packet loss is avoided, and in addition, compared with a mode that the first auxiliary node requests the master node to allocate the measurement interval again, signaling cost and time delay are saved. If the trigger node is the second auxiliary node, the first auxiliary node further judges whether the first auxiliary node has the requirement of enabling the terminal equipment to conduct different-frequency or different-system measurement, so that the resource waste caused by scheduling of the terminal equipment still needs to be stopped within the measurement interval when the first auxiliary node does not have the requirement of enabling the terminal equipment to conduct different-frequency or different-system measurement.

Since the method provided in this embodiment is provided in the scenario where the secondary node connected to the terminal device changes, where the primary node connected to the terminal device is default to not change, if the measurement interval configuration is triggered by the primary node, or the primary node and the second secondary node are triggered together, the measurement interval configuration is applicable to the first secondary node, and S402 may be implemented as follows:

And if the information of the trigger node indicating the measurement interval configuration indicates that the trigger node is the master node, the measurement interval configuration is sent to the first auxiliary node, and if the information of the trigger node indicating the measurement interval configuration indicates that the trigger node is the master node and the second auxiliary node, the measurement interval configuration is also sent to the first auxiliary node. Because the first auxiliary node and the main node are both provided with the measurement interval configuration, the main node and the first auxiliary node have consistent understanding on the measurement interval, so that when the terminal equipment performs different frequency or different system measurement in the measurement interval, the main node and the first auxiliary node can not schedule the terminal equipment, and packet loss is avoided. If the information of the trigger node indicating the measurement interval configuration indicates that the trigger node is the second auxiliary node, the measurement interval configuration is not sent to the first auxiliary node, so that the resource waste caused by stopping scheduling of the terminal equipment in the measurement interval when the first auxiliary node does not have the requirement of making the terminal equipment perform different frequency or different system measurement is avoided.

According to the configuration method of the measurement interval, after the auxiliary node connected with the terminal equipment is changed into the first auxiliary node from the second auxiliary node, the main node determines whether to send the measurement interval configuration to the first auxiliary node according to the information of the trigger node indicating the measurement interval configuration, and when the trigger node is the main node or the trigger node is the main node and the second auxiliary node, the measurement interval configuration is sent to the first auxiliary node, so that the main node and the first auxiliary node can understand the measurement interval consistently, packet loss is avoided, and in addition, compared with the mode that the first auxiliary node requests the main node to allocate the measurement interval again, signaling cost and time delay are saved. When the trigger node is the second auxiliary node, the measurement interval configuration is not sent to the first auxiliary node, so that the resource waste caused by stopping scheduling of the terminal equipment in the measurement interval can be avoided when the first auxiliary node does not have the requirement of enabling the terminal equipment to perform different frequency or different system measurement.
