Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method and device for configuring a measurement interval. Background Art

[0002] In the Multi-Radio DC (MR-DC) scenario, the terminal device is connected to the master node and the slave node at the same time. When the master node and / or the slave node have the need to make the terminal device perform hetero-frequency or hetero-system measurements, it will trigger the generation of the measurement interval configuration of the terminal device. During the measurement interval, the master node and the slave node will not schedule the terminal device.

[0003] As the terminal device moves, the secondary node to which the terminal device is connected may change. If the primary node and the changed secondary node cannot agree on the measurement interval, the changed secondary node may schedule the terminal device within the measurement interval, resulting in packet loss. Summary of the invention

[0004] The present application provides a method and device for configuring a measurement interval, which are used to prevent packet loss caused by invalid scheduling of the terminal device by a secondary node to which the terminal device is connected after the secondary node changes.

[0006] In the above method, after the auxiliary node to which the terminal device is connected changes from the second auxiliary node to the first auxiliary node, the main node sends the measurement interval configuration of the terminal device before the auxiliary node changes and the first indication information to the first auxiliary node. When the first auxiliary node has a need to make the terminal device perform hetero-frequency or hetero-system measurements, the measurement interval configuration takes effect, so that the main node and the first auxiliary node have a consistent understanding of the measurement interval, thereby avoiding packet loss. In addition, compared with the method in which the first auxiliary node requests the main node to configure a measurement interval for it again, signaling overhead is saved and latency is reduced. When the first auxiliary node does not have a need to make the terminal device perform hetero-frequency or hetero-system measurements, the measurement interval configuration does not take effect, which can avoid the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not have a need to make the terminal device perform hetero-frequency or hetero-system measurements.

[0017] In the above method, after the auxiliary node to which the terminal device is connected changes from the second auxiliary node to the first auxiliary node, the main node sends the measurement interval configuration and the information of the triggering node indicating the measurement interval configuration to the first auxiliary node. If the triggering node is the main node, or the main node and the second auxiliary node, the first auxiliary node will take effect on the measurement interval configuration, so that the main node and the first auxiliary node have a consistent understanding of the measurement interval, thus avoiding packet loss. In addition, compared with the method in which the first auxiliary node requests the main node to configure the measurement interval for it again, signaling overhead and delay are saved. If the triggering node is the second auxiliary node, the first auxiliary node further determines whether the first auxiliary node has a need to make the terminal device perform hetero-frequency or hetero-system measurements, thus avoiding the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not have a need to make the terminal device perform hetero-frequency or hetero-system measurements.

When the triggering node is the main node, or when the triggering 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 have a consistent understanding of the measurement interval, thereby avoiding packet loss.

The primary base station and the secondary base station in the communication system can be base stations of the same type or different types. The primary base station and the secondary base station can communicate with the terminal device or communicate with the terminal device through a relay station.

[0050] In the MR-DC scenario, the primary base station and the secondary base station have the following combinations:

[0051] 1) When the core network is a 4G core network (Evolved Packet Core, referred to as EPC), the Long Term Evolution (LTE) base station is the main base station, and the New Radio (NR) base station is the auxiliary base station. At this time, there is an X2 interface between the LTE base station and the NR base station, and there is at least a control plane connection between the LTE base station and the NR base station, and there may also be a user plane connection; there is an S1 interface between the LTE base station and the EPC, and there is at least a control plane connection between the LTE base station and the EPC, and there may also be a user plane connection; there is an S1-U interface between the NR base station and the EPC, and there may only be a user plane connection. At this time, the LTE base station can provide air interface resources for the terminal device through at least one LTE cell, and the at least one LTE cell is called a master cell group (MasterCell Group, referred to as MCG). Correspondingly, the NR base station can also provide air interface resources for the terminal device through at least one NR cell, and the at least one NR cell is called a secondary cell group (Secondary Cell Group, referred to as SCG).

[0052] 2) When the core network is the 5G core network 5GC, the LTE base station serves as the main base station and the NR base station serves as the axis base station. At this time, there is an Xn interface between the LTE base station and the NR base station, and there is at least a control plane connection between the LTE base station and the NR base station, and there may also be a user plane connection; there is an NG interface between the LTE base station and the 5GC, and there is at least a control plane connection between the LTE base station and the 5GC, and there may also be a user plane connection; there is an NG-U interface between the NR base station and the 5GC, and there may only be a user plane connection. At this time, the LTE base station can provide air interface resources for the terminal device through at least one LTE cell, and the at least one LTE cell is called MCG. Correspondingly, the NR base station can also provide air interface resources for the terminal device through at least one NR cell, and the at least one NR cell is called SCG.

[0053] 3) When the core network is the 5G core network 5GC, the NR base station serves as the main base station and the LTE base station serves as the auxiliary base station. At this time, there is an Xn interface between the NR base station and the LTE base station, and there is at least a control plane connection between the NR base station and the LTE base station, and there may also be a user plane connection; there is an NG interface between the NR base station and the 5GC, and there is at least a control plane connection between the NR base station and the 5GC, and there may also be a user plane connection; there is an NG-U interface between the NR base station and the 5GC, and there may only be a user plane connection. At this time, the NR base station can provide air interface resources for the terminal device through at least one NR cell, and the at least one NR cell is called MCG. Correspondingly, the LTE base station can also provide air interface resources for the terminal device through at least one LTE cell, and the at least one LTE cell is called SCG.

[0054] 4) When the core network is the 5G core network 5GC, both the primary and secondary base stations are NR base stations. The interface between the primary and secondary base stations is the Xn interface. There is at least a control plane connection between the primary and secondary base stations, and there may also be a user plane connection; there is an NG interface between the NR primary base station and the 5GC, at least a control plane connection, and there may also be a user plane connection; there is an NG-U interface between the NR secondary base station and the 5GC, and there may only be a user plane connection. At this time, the NR primary base station can provide air interface resources for the terminal device through at least one NR cell, and the at least one NR cell is called MCG. Correspondingly, the NR secondary base station can also provide air interface resources for the terminal device through at least one NR cell, and the at least one NR cell is called SCG.

[0055] The following are some explanations of the terms used in this application:

[0056] Primary node and secondary node: In the MR-DC scenario, the terminal device is connected to both the primary node and the secondary node. The primary node is the primary base station to which the terminal device is connected, and the secondary node is the secondary base station to which the terminal device is connected.

[0057] Measurement interval configuration: When the master node or the slave node has the need to make the terminal device perform heterofrequency or heterosystem measurements, the master node sends measurement information, which includes the measurement interval configuration, specifically, it may include the measurement interval repetition period, the measurement interval length, one or more of the offsets of the measurement interval pattern within the measurement interval repetition period, and optionally, it may also include which cell or node frame number / subframe number is used as a reference when calculating the measurement interval. The terminal device can calculate the corresponding measurement interval based on the measurement interval configuration and perform the above-mentioned heterofrequency or heterosystem measurements within the measurement interval. Since the terminal device may need to switch the RF module when performing heterofrequency or heterosystem measurements, the protocol defines that the master node and the slave node do not schedule the terminal device within the measurement interval.

[0058] As the terminal device moves, the secondary node to which the terminal device is connected may change. If the primary node and the changed secondary node cannot agree on the measurement interval, the changed secondary node may schedule the terminal device within the measurement interval, resulting in packet loss.

[0059] In order to solve the above technical problems, Figure 2 This is a flow chart of the first embodiment of the configuration method of the measurement interval provided by the present application. In this embodiment, the secondary node to which the terminal device is connected after the secondary node changes is called the first secondary node, and the secondary node to which the terminal device is connected before the secondary node changes is called the second secondary node. Figure 2 As shown, the configuration method of the measurement interval provided in this embodiment includes:

[0060] S201. The master node obtains the measurement interval configuration of the terminal device before the axis node changes.

[0061] S202: The primary node sends a measurement interval configuration and first indication information to the first secondary node.

[0062] Among them, when the node has a need to make the terminal device perform heterofrequency or heterosystem measurement, it will trigger the generation of the measurement interval configuration of the terminal device. The measurement interval configuration of the terminal device before the auxiliary node changes obtained by the master node in S201 may be triggered by the master node, or by the second auxiliary node, or by the master node and the second auxiliary node together.

[0063] If the measurement interval configuration mentioned in S201 is triggered by the second secondary node, as described in S202, when the primary node sends the measurement interval configuration to the first secondary node, it may simultaneously send the first indication information, and the first indication information is used to inquire whether the measurement interval configuration is valid. The first indication information is used to inquire whether the measurement interval configuration is valid, which can be understood as the first indication information is used to inquire whether the first secondary node takes effect for the measurement interval configuration, or to inquire whether the first secondary node accepts the measurement interval configuration, or to inquire whether the first secondary node needs the measurement interval configuration, etc., and the implementation methods of the present application are not limited to this.

[0064] The following describes the process of the second auxiliary node triggering the generation of the above measurement interval configuration:

[0065] When the second auxiliary node has a need to make the terminal device perform heterofrequency or heterosystem measurements, the need is sent to the main node. After receiving the need, the main node generates a measurement interval configuration and sends the measurement interval configuration to the second auxiliary node. The second auxiliary node further sends the measurement interval configuration to the terminal device, or the main node sends the measurement interval configuration to the terminal device. Since the main node and the second auxiliary node are both equipped with the measurement interval configuration, the main node and the second auxiliary node have a consistent understanding of the measurement interval, so that when the terminal device performs heterofrequency or heterosystem measurements within the measurement interval, the main node and the second auxiliary node will not schedule the terminal device, thereby avoiding packet loss.

[0066] S203: The first secondary node determines whether the measurement interval configuration is valid according to the first indication information.

[0067] In one possible implementation, the first auxiliary node determines whether there is a need for the first auxiliary node to make the terminal device perform heterofrequency or heterosystem measurements. If so, it is determined that the received measurement interval configuration is valid. Since the first auxiliary node and the main node are both equipped with the measurement interval configuration, the main node and the first auxiliary node have a consistent understanding of the measurement interval, so that when the terminal device performs heterofrequency or heterosystem measurements within the measurement interval, the main node and the first auxiliary node will not schedule the terminal device, thereby avoiding packet loss; if not, it is determined that the received measurement interval configuration is invalid. It can be seen that the setting of the first indication message allows the first auxiliary node to have room for judgment. Compared with the method in which the main node only sends the measurement interval configuration to the first auxiliary node and the first auxiliary node directly takes effect on the measurement interval configuration, the method of this embodiment can avoid the waste of resources caused by stopping scheduling the terminal device within the measurement interval when the first auxiliary node itself does not have the need to make the terminal device perform heterofrequency or heterosystem measurements.

[0068] S204. The first secondary node sends a second indication message to the primary node.

[0069] Specifically, if the first secondary node determines that the above 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 secondary node will take effect on the measurement interval configuration, or is used to indicate that the first secondary node accepts the measurement interval configuration, or is used to indicate that the first secondary node needs the measurement interval configuration. If the first secondary node determines that the above measurement interval configuration is invalid, the second indication information is used to indicate that the measurement interval configuration is invalid, or is used to indicate that the first secondary node will not take effect on the measurement interval configuration, or is used to indicate that the first secondary node does not accept the measurement interval configuration, or is used to indicate that the first secondary node does not need the measurement interval configuration.

[0070] In a possible implementation, the second indication information may be a certain information element, and when the value of the information element is 1, it indicates that the measurement interval configuration is valid; and when the value of the information element is 0, it indicates that the measurement interval configuration is invalid.

[0071] The configuration method of the measurement interval provided in this embodiment is that after the auxiliary node to which the terminal device is connected changes from the second auxiliary node to the first auxiliary node, the main node sends the measurement interval configuration of the terminal device before the axis node change and the first indication information to the first auxiliary node. When the first auxiliary node has a need to make the terminal device perform hetero-frequency or hetero-system measurements, the measurement interval configuration takes effect, so that the main node and the first auxiliary node have a consistent understanding of the measurement interval, thereby avoiding packet loss. In addition, compared with the method in which the first auxiliary node requests the main node to configure a measurement interval for it again, signaling overhead and delay are saved. When the first auxiliary node does not have a need to make the terminal device perform hetero-frequency or hetero-system measurements, the measurement interval configuration does not take effect, which can avoid the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not have a need to make the terminal device perform hetero-frequency or hetero-system measurements.

[0072] Figure 3 This is a flow chart of the second embodiment of the configuration method of the measurement interval provided by the present application. Similar to the above embodiment, in this embodiment, the secondary node to which the terminal device is connected after the secondary node changes is called the first secondary node, and the secondary node to which the terminal device is connected before the secondary node changes is called the second secondary node. Figure 3 As shown, the configuration method of the measurement interval provided in this embodiment includes:

[0073] S301: The primary node obtains the measurement interval configuration of the terminal device before the secondary node changes and information of the triggering node indicating the measurement interval configuration.

[0074] S302: The primary node sends a measurement interval configuration and information indicating a triggering node of the measurement interval configuration to the first secondary node.

[0075] Referring to the description of S202 in the above embodiment, the above measurement interval configuration may be triggered by the primary node, may be triggered by the second secondary node, or may be triggered by the primary node and the second secondary node together. The above information indicating the triggering node of the measurement interval configuration may be used to indicate whether the triggering node is the primary node, the second secondary node, or the primary node and the second secondary node.

[0076] The process of the second auxiliary node triggering the generation of the measurement interval configuration is referred to S202 in the above embodiment, and will not be described in detail in this application.

[0077] The following describes the process of triggering the master node to generate the measurement interval configuration:

[0078] When the main node has the need to make the terminal device perform heterofrequency or heterosystem measurements, it generates a measurement interval configuration and sends the measurement interval configuration to the second auxiliary node and the terminal device. Since both the main node and the second auxiliary node are equipped with the measurement interval configuration, the main node and the second auxiliary node have a consistent understanding of the measurement interval, so when the terminal device performs heterofrequency or heterosystem measurements within the measurement interval, the main node and the second auxiliary node will not schedule the terminal device, thereby avoiding packet loss.

[0079] The following describes the process of the primary node and the secondary node jointly triggering the generation of the measurement interval configuration:

[0080] When the second auxiliary node has a need to make the terminal device perform heterofrequency or heterosystem measurements, the need is sent to the main node. The main node generates a measurement interval configuration based on the need and its own needs, and sends the measurement interval configuration to the second auxiliary node and the terminal device. Since both the main node and the second auxiliary node are equipped with the measurement interval configuration, the main node and the second auxiliary node have a consistent understanding of the measurement interval, so that when the terminal device performs heterofrequency or heterosystem measurements within the measurement interval, the main node and the second auxiliary node will not schedule the terminal device, thereby avoiding packet loss.

[0081] S303: The first secondary node determines whether the measurement interval configuration is valid according to the information of the triggering node indicating the measurement interval configuration.

[0082] Since the method provided in this embodiment is proposed in the scenario that the secondary node to which the terminal device is connected changes, and the scenario assumes that the primary node to which the terminal device is connected does 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, then the measurement interval configuration is applicable to the first secondary node, and S303 can be implemented in the following manner:

[0083] If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node is the main node, then the measurement interval configuration is determined to be valid. If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node includes a main node and a second auxiliary node, then the measurement interval configuration is also determined to be valid. Since the first auxiliary node and the main node are both equipped with the measurement interval configuration, the main node and the first auxiliary node have a consistent understanding of the measurement interval, so that when the terminal device performs hetero-frequency or hetero-system measurements within the measurement interval, the main node and the first auxiliary node will not schedule the terminal device, thereby avoiding packet loss. If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node is the second auxiliary node, it is further determined whether the first auxiliary node has a need to enable the terminal device to perform hetero-frequency or hetero-system measurements. If so, then the measurement interval configuration is determined to be valid; if not, then the measurement interval configuration is determined to be invalid. It can be seen that the information of the triggering node indicating the measurement interval configuration sent by the main node to the first auxiliary node allows the first auxiliary node to have room for judgment. Compared with the manner in which the main node only sends the measurement interval configuration to the first auxiliary node and the first auxiliary node directly takes effect on the measurement interval configuration, the method of this embodiment can avoid the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not have the need to make the terminal device perform hetero-frequency or hetero-system measurements.

[0084] S304. The first secondary node sends a second indication message to the primary node.

[0085] Specifically, if the first secondary node determines that the above 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 secondary node will take effect on the measurement interval configuration, or is used to indicate that the first secondary node accepts the measurement interval configuration, or is used to indicate that the first secondary node needs the measurement interval configuration. If the first secondary node determines that the above measurement interval configuration is invalid, the second indication information is used to indicate that the measurement interval configuration is invalid, or is used to indicate that the first secondary node will not take effect on the measurement interval configuration, or is used to indicate that the first secondary node does not accept the measurement interval configuration, or is used to indicate that the first secondary node does not need the measurement interval configuration.

[0086] In a possible implementation, the second indication information may be a certain information element, and when the value of the information element is 1, it indicates that the measurement interval configuration is valid; and when the value of the information element is 0, it indicates that the measurement interval configuration is invalid.

[0087] The configuration method of the measurement interval provided in this embodiment is that after the auxiliary node to which the terminal device is connected changes from the second auxiliary node to the first auxiliary node, the main node sends the measurement interval configuration and the information of the triggering node indicating the measurement interval configuration to the first auxiliary node. If the triggering node is the main node, or the main node and the second auxiliary node, the first auxiliary node will take effect on the measurement interval configuration, so that the main node and the first auxiliary node have a consistent understanding of the measurement interval, avoiding packet loss. In addition, compared with the method in which the first auxiliary node requests the main node to configure the measurement interval for it again, it saves signaling overhead and delay. If the triggering node is the second auxiliary node, the first auxiliary node further determines whether the first auxiliary node has the need to make the terminal device perform hetero-frequency or hetero-system measurements, which can avoid the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not have the need to make the terminal device perform hetero-frequency or hetero-system measurements.

[0088] Figure 4 This is a flow chart of the third embodiment of the configuration method of the measurement interval provided by the present application. Similar to the above embodiment, in this embodiment, the secondary node connected to the terminal device after the secondary node changes is called the first secondary node, and the secondary node connected to the terminal device before the secondary node changes is called the second secondary node. The method provided in this embodiment can be applied to the primary node. Figure 4 As shown, the configuration method of the measurement interval provided in this embodiment includes:

[0089] S401: The primary node obtains the measurement interval configuration of the terminal device before the secondary node changes and information of the triggering node indicating the measurement interval configuration.

[0090] Wherein, referring to the description of S202 in the above embodiment, the above measurement interval configuration may be triggered by the main node, may be triggered by the second auxiliary node, or may be triggered by the main node and the second auxiliary node together. The above information indicating the triggering node of the measurement interval configuration may be used to indicate whether the triggering node is the main node, the second auxiliary node, or the main node and the second axis node.

[0091] S402: Determine whether to send the measurement interval configuration to the first secondary node according to information of the triggering node indicating the measurement interval configuration.

[0092] Since the method provided in this embodiment is proposed in the scenario that the secondary node to which the terminal device is connected changes, and the scenario assumes that the primary node to which the terminal device is connected does 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, then the measurement interval configuration is applicable to the first secondary node, and S402 can be implemented in the following manner:

[0093] If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node is the master node, the measurement interval configuration is sent to the first slave node. If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node is the master node and the second slave node, the measurement interval configuration is also sent to the first slave node. Since the first slave node and the master node are both equipped with the measurement interval configuration, the master node and the first slave node have a consistent understanding of the measurement interval, so that when the terminal device performs hetero-frequency or hetero-system measurements within the measurement interval, the master node and the first slave node will not schedule the terminal device, thereby avoiding packet loss. If the information of the triggering node indicating the measurement interval configuration indicates that the triggering node is the second slave node, the measurement interval configuration is not sent to the first slave node, thereby avoiding the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first slave node itself does not need to make the terminal device perform hetero-frequency or hetero-system measurements.

[0094] The configuration method of the measurement interval provided by the present embodiment is that after the auxiliary node to which the terminal device is connected changes from the second auxiliary node to the first auxiliary node, the main node determines whether to send the measurement interval configuration to the first auxiliary node based on the information of the triggering node indicating the measurement interval configuration. When the triggering node is the main node, or when the triggering 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 have a consistent understanding of the measurement interval, thereby avoiding packet loss. In addition, compared with the method in which the first auxiliary node requests the main node to configure the measurement interval for it again, signaling overhead and delay are saved. When the triggering node is the second auxiliary node, the measurement interval configuration is not sent to the first auxiliary node, which can avoid the waste of resources caused by stopping the scheduling of the terminal device within the measurement interval when the first auxiliary node itself does not need to make the terminal device perform hetero-frequency or hetero-system measurements.
