Background technique

For data replication and transmission, the uplink PDCP data replication function can be configured based on DRB, that is to say, different DRBs can be configured to support PDCP replication data transmission or not configured for PDCP replication data transmission. The corresponding configuration mode of data replication, or activation/deactivation mode, is also carried out based on the bearer.

However, Release 16 puts forward a higher demand for data replication and transmission characteristics, and the system can implement a more flexible and effective data replication method. In the prior art, only the activation/deactivation of MAC CE can be used to control the on or off of data replication transmission. The disadvantage of the prior art is that this method based on the MAC CE indication, in the scenario of flexible change required by R16 data duplication, will bring a lot of disadvantages of air interface signaling overhead, which in turn needs to be avoided by the 5G system.

In addition, in the prior art, the configuration of data replication transmission is based on the bearer configuration, and the corresponding activation/deactivation mode is also indicated by the bearer level. The disadvantage of the prior art is that this type of configuration or activation/deactivation indication method based on the bearer level will increase the processing complexity of terminal equipment and network equipment, increase the air interface overhead, and there is also the inability to control activation/deactivation more flexibly.

In order to understand the features and technical contents of the embodiments of the present invention in more detail, the following describes the implementation of the embodiments of the present invention in detail with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the embodiments of the present invention.

Example one

The embodiment of the present invention provides a method for controlling data replication and transmission, which is applied to a terminal device. As shown in FIG. 2, the method includes:

Step 21: Based on at least one time interval for the at least one object, control the change of the data replication transmission mode of the at least one object.

In this embodiment, the time interval is controlled by a timer, that is to say, different time intervals can be provided for different objects, and then different timers can be used for different objects.

It should be pointed out that in the embodiment, the time interval is controlled by a timer, and it can also be implemented in other ways, but it is not limited in this embodiment.

Before step 21 is performed, the method may further include: receiving at least one timer configured by the network device for at least one object.

The granularity of the object is one of the following: bearer, terminal device, data packet, QoS (Quality of Service) data flow Flow, logical channel, cell group (CG, Cell Group). The durations of timers for different objects of the same granularity are different or the same.

The foregoing time interval may have a one-to-one correspondence with the object. For example, in terms of the granularity of the bearer, bearer 1 corresponds to time interval 1 and bearer 2 corresponds to time interval 2, and

time intervals

1 and 2 may be different. Of course, other granularities can also be used, which is not exhaustive here.

Correspondingly, the correspondence between timers and objects is also one-to-one correspondence, and the duration of timers of different objects, that is, the time interval may be the same or different. For example, different bearers can correspond to different timer durations. Assuming that there are currently three bearers, then the duration of timer 1 of bearer 1 can be A, and the duration of timer 2 of bearer 2 can be B; it can also correspond to different bearers. The duration of the same timer, for example, the duration of timer 3 of bearer 3 is A, which is the same as bearer 1.

The other granularity is also the same, but it is not exhaustively listed in this embodiment.

The bearer in this embodiment may be a data bearer (DRB, Data Resource Bearer) and/or a signaling bearer (SRB, Signal Resource Bearer).

In summary, this embodiment can introduce timers for different bearers, such as DRB. In this way, a new deactivation method can be added for data replication transmission, thereby reducing the air interface signaling overhead caused by the activation/deactivation signaling interaction.

In addition, due to the introduction of more different granular timer control methods, such as DRB-based timers, logical channel-based timers, packet-based timers, and QoS flow-based timers. Thereby increasing the flexible control method of data replication and transmission.

Further, after the timer provided in this application expires, the data replication transmission mode of the corresponding object at the corresponding granularity is deactivated/activated, that is, the state of the corresponding object using data replication transmission or not using data replication transmission. Specifically, when a certain object is in the active state, or the state of using data copy transmission, if the timer expires, the object can be controlled to be in the deactivated state or the state of not using data copy transmission. Or, vice versa, that is, when a certain object is in the deactivated state, or the state of not using data copy transmission, if the timer expires, the object can be controlled to be in the active state or the state of using data copy transmission.

The receiving network device configuring at least one timer for at least one object further includes:

Through a radio resource control (RRC, Radio Resource Control) reconfiguration message, the configuration information notified by the network device and at least one timer for at least one object are acquired.

Wherein, the configuration information may be information available in the prior art, which may include an instruction for an initial data replication transmission mode for at least one object. The specific instruction mode is not repeated here.

The aforementioned at least one object may be an object with the same granularity, or of course, it may also be an object with a different granularity. For example, at least one timer can be configured for at least one DRB, or at least one timer can be configured for at least one DRB and at least one CG, of course, it can also be other cases, but it is not exhaustive.

Further, the initial state of the timer can be a stopped state or an open state; that is, when the initial state of the timer is the stopped state, that is, when the timer is configured to the terminal device, it is in the stopped state, Of course, it can also be in the on state, that is, the timer is in the on state as soon as the terminal device is configured.

Correspondingly, the initial state of the timer includes:

The timer is bound to the initial data replication transmission mode; or,

The timer is not bound to the initial data replication transmission mode.

When the initial state of the timer is bound to the initial data replication transmission mode, the method further includes one of the following:

When the object's initial data replication transmission mode is deactivated, the control timer stops;

When the object's initial data replication transmission mode is activated, the control timer is started or restarted;

When the object's initial data replication transmission mode is activated, the control timer stops;

When the object's initial data copy transmission mode is deactivated, the control timer is started or restarted.

Specifically, when the initial state of the timer has a binding relationship with the initial data copy transmission mode of the timer object, it can be set to determine the initial state of the timer to start or when the initial data copy transmission is activated. Restart, when the initial data copy transmission is deactivated, it can be determined that the initial state of the timer is stopped, or the timer does not start. The opposite can also be defined accordingly. For example, when the initial data copy transmission mode is deactivated, the initial state of the timer is determined to be start or restart, and when the initial data copy transmission mode is active, the initial state of the timer is determined To stop or not to start.

When the initial state of the timer is not bound to the initial data replication transmission mode, the method further includes:

When receiving the configuration message corresponding to the object, control to start or restart the timer; or,

When the configuration message corresponding to the object is received, the control does not start the timer; or,

When a dedicated message corresponding to the object is received, the timer is controlled to start or restart, and the dedicated message is used to start or restart the timer in a state where the timer is stopped by default.

In this case, the initial state of the timer is not limited by the object's initial data replication transmission mode, but is determined according to the configuration message or dedicated message whether to start or restart the timer, or to determine whether the initial state of the timer is not start up.

The dedicated message can be sent to the terminal device by carrying other information, such as MAC CE, RRC, or DCI. In the dedicated message, when the timer for a certain object is stopped, control according to the dedicated message The initial state of the timer is start or restart; the dedicated message may include the identification information of the object and the specific message content indicating the start or restart of the timer. Of course, it may also contain other content, but it is not exhaustive here.

Further, after the receiving network device configures at least one timer for at least one object, the method further includes:

Obtain the first information sent by the network device through one of MAC CE, RRC messages, and DCI;

Wherein, the first information is used to indicate whether to change or not change the data copy transmission mode of the object.

In other words, after the timer is configured, the network device may also send a change instruction for the data replication transmission mode to the terminal device.

Based on the first information, there are several different situations:

Case 1. When the first information indicates that the first object changes the data replication transmission mode, control to start or restart the timer corresponding to the first object;

For example, when the current data replication transmission mode of the first object is in the deactivated state, or the current data replication transmission mode is not used, the first message is received, which indicates that the first object changes the data replication transmission mode, and it can be determined to pass the first object. A message changes the first object to the activated state or uses the data copy transmission state. At this time, it is determined to start or restart the timer of the first object.

Of course, there can also be an opposite processing method. For example, when the current data copy transmission mode of the first object is active, or the current data copy transmission mode is used, the first message is received, which indicates that the first object changes data In the replication transmission mode, it can be determined that the first object is changed to the deactivated state or the state of not using data replication transmission through the first message. At this time, it is determined to start or restart the timer of the first object.

In specific use, which processing method can be determined according to the actual situation, which is not limited in this embodiment.

Case 2. When the first information indicates that the first object does not change the data replication transmission mode, control to keep the timer state of the first object unchanged, or restart the timer if the timer is running at this time;

For example, when the current data replication transmission mode of the first object is in the deactivated state, or the current data replication transmission mode is not used, the first message is received, which indicates that the first object does not change the data replication transmission mode, and the first object can be determined When an object keeps the data copy transmission mode in deactivated state, or keeps the state of not using data copy transmission, at this time, determine the timer state of the first object unchanged, or restart the timer if the timer is running at this time For example, when the timer is in the running state, the timer is still in the running state, or the timer is currently in the stopped state, and the timer can be kept in the stopped state.

Of course, there can also be the opposite processing method, which will not be repeated here.

Case 3: When the first information does not include a message for the first object, control to keep the timer state of the first object unchanged;

In this case, the first information is not a change instruction for the first object, so the timer state of the first object remains unchanged. For example, if it was in the running state, it will remain in the running state. If it is in the stopped state, it will remain stopped. status.

Case 4. When the first object indicated by the first information changes the data replication transmission mode, and the first object contains at least one other object, control to start or restart the timer corresponding to the at least one other object, and/or , Changing the data replication transmission mode in which the first object includes at least one other object; wherein the granularity of the first object and other objects are different, and the granularity of the different other objects is the same or different;

In this case, the first object may contain other objects with a smaller granularity. For example, when the first object is a terminal device, other objects with a smaller granularity may be DRB, QoS Flow, logical channels, etc., then Other objects, such as DRB, QoS Flow, and at least one timer corresponding to the logical channel, can all be started or restarted; furthermore, when the data replication transmission of other objects is currently active, the first object is received When the first information of the data replication transmission mode is changed, at least one other object included in the first object can be changed to a deactivated state, and/or the timer of other objects can be controlled to start or restart. The opposite is also true, but I won't repeat it.

For another example, if the change is for the bearer, the timer for each logical channel, cell group, data packet, and QoS flow contained in the bearer must be started or restarted, and/or, for each logical channel, cell group, data packet, and QoS flow Copy data transfer changes. Taking the logical channel as an example, the data replication transmission of the logical channel is in the deactivated state, after receiving the first information, the data replication transmission mode of the control logical channel is activated, and the timer corresponding to the logical channel is started or restarted; Likewise, no exhaustive list. In addition, the processing methods for the other objects mentioned above can be the same, and will not be repeated here.

Case 5. When the first information indicates that the changed data transmission mode of the first object is the first mode, control to start or restart the timer corresponding to the first object;

Case 6. When the first information indicates that the changed data transmission mode of the first object is the second mode, control to stop the timer corresponding to the first object; wherein the first mode is different from the second mode;

For situations 5 and 6, the first method is different from the second method. For example, when the first method is activation, the second method is deactivation; when the first method is deactivation, the second method is The way is activation.

Take the first method as activation as an example. That is to say, when the first object (such as DRB) is currently (or originally) in the deactivated state, then the first information is received to control the first object to change to the first Mode, namely the activated state, at this time, the timer of the first object can be controlled to start or restart;

When the first object, such as DRB, is currently in the active state, the timer can be in the running state or, of course, it can also be in the stopped state. However, as long as it is received to indicate that the first object is changed to the deactivated state, it is based on the first A message controls the deactivation of the data copy transmission mode of the first object, and the control timer is in a stopped state.

It should be understood that the above only provides a description of a scenario. On the contrary, that is, the first method is deactivation and the second method is activation, which can be the same processing as above, but the final control method of the timer is reversed. Here No longer.

Case 7. When the first information indicates that the data transmission mode of the first object is changed to the first mode, and the first object contains at least one other object, change the data transmission mode of at least one other object, and/or control Start or restart at least one timer corresponding to other objects;

Case 8. When the first information indicates that the data transmission mode of the first object is changed to the second mode, and the first object includes at least one other object, change the data transmission mode of at least one other object, and/or control Stop the timer corresponding to at least one other object.

Cases 7 and 8 are also described together, and the first and second methods can be the same as cases 5 and 6, and will not be repeated. Further, cases 7 and 8 are different from cases 5 and 6 in that the first information of the first object can be controlled by the timer of at least one other object contained in the first object. For example, when the first object is a DRB At this time, the other objects can be at least one logical channel included in the DRB, then the first information for the first object is changed to the first way, for example, when in the active state, at least one other object, that is, the corresponding logical channel can be controlled The timer starts or restarts. Of course, the reverse is also possible, that is, when the first method is deactivation, the timer of at least one other object can be controlled to start or restart.

In addition, when the first object is a DRB, receiving the first information for the first object is to change to the second mode, that is, the deactivated state, and the timer of at least one logical channel (that is, at least one other object) can be controlled to stop. The opposite is also possible. For example, the second mode is the active state, and the timer of at least one other object can be controlled to stop.

While the timer of the first object is running, it can be processed based on the following situations:

Case 1. During the operation of the timer of the first object, when the first information instructs the first object to change the data replication transmission mode, the data replication transmission mode of the first object is changed according to the first information, and the first object is controlled. The timer of the object stops;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object is in a deactivated state for data replication and transmission, and the timer controlling the first object is stopped.

Of course, the reverse is also true. For example, when the timer of the first object is running, the first object can be in the deactivated state for data replication and transmission. Then, when the first information indicates that the first object is changed to active, it can be A message controls the first object to be in a data replication transmission active state, and controls the timer of the first object to stop.

Case 2. During the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, and the first object contains at least one other object, compare at least one other object according to the first information The object’s data replication transmission mode is changed, and/or the timer controlling at least one other object is stopped;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object and at least one other object contained therein are in a data replication transmission deactivated state, and/or a timer controlling the first object and at least one other object contained therein is stopped.

Of course, the reverse is also true. For example, when the timer of the first object is running, at this time, the first object can be in the deactivated state for data copy transmission, and then the first information indicates that the first object is changed to active according to the A message controls the first object and at least one other object contained in it to be in a data replication transmission active state, and controls the timer of the first object and at least one other object contained in it to stop. For the description of the first object and other objects, please refer to the above description, and the description will not be repeated here.

Case 3. During the running of the timer of the first object, when the first information instructs the first object to change the data replication transmission mode, change the data replication transmission mode of the first object according to the first information, and control the first object Start or restart the timer;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object is in a deactivated state for data replication and transmission, and controls the timer of the first object to start or restart.

Of course, the reverse is also true. For example, when the timer of the first object is running, the first object can be in the deactivated state for data replication and transmission. Then, when the first information indicates that the first object is changed to active, it can be A message controls the first object to be in a data replication transmission active state, and controls the timer of the first object to start or restart.

Case 4. During the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, and the first object contains at least one other object, compare at least one other object according to the first information Change the object’s data replication and transmission mode, and/or control the start or restart of the timer of at least one other object;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object and at least one other object contained therein are in a data replication transmission deactivated state, and/or a timer controlling the first object and at least one other object contained therein is started or restarted.

Of course, the reverse is also true. For example, when the timer of the first object is running, the first object can be in the deactivated state for data replication and transmission. Then, when the first information indicates that the first object is changed to active, it can be One piece of information controls the first object and at least one other object contained in it to be in a data replication transmission active state, and controls the timer of the first object and at least one other object contained in it to start or restart. For the description of the first object and other objects, please refer to the above description, and the description will not be repeated here.

Case 5. During the running of the timer of the first object, when the first information for the first object is received, the data copy transmission mode of the first object is kept unchanged.

This situation indicates that the first object is controlled based on the timer, that is, as long as the timer of the first object is running, regardless of whether it receives the first message and requires it to change the data replication transmission mode, the timer is used as Yes, the data copy transmission mode of the first object is not adjusted according to the first information.

When the timer of the first object expires, control to change the data replication transmission mode of the first object; or, when the timer of the first object expires, control does not change the data replication transmission mode of the first object.

In other words, if the timer expires, the first object can be controlled to change from the current data copy transmission mode to another data copy transmission mode, for example, to change the first object from the active state of the data copy transmission mode to the deactivated state ,vice versa. It is also necessary to understand that when the timer of the first object expires, at least one other object contained in the first object can be controlled to change the data replication transmission mode. For example, when the DRB timer expires, the control contains at least one logic The channel changes the data replication transmission mode, for example, from activated to deactivated.

Of course, it is also possible not to control the change of the data replication transmission mode of the first object based on the timer, that is, the timer expires without changing the data replication transmission mode of the first object, for example, the first object remains activated or deactivated. In this case, the data copy transmission mode of the first object can be controlled and changed according to the first information or other information, that is, a control mode based on the instruction information.

The above implementation will be described in detail below in conjunction with multiple examples:

Example 1.

Due to the limited air interface resources, it is necessary to consider how to reduce the signaling overhead that can be omitted between the UE and the base station. Therefore, introducing a timer-based data replication transmission control method has the advantage of adding a new deactivation/activation method, reducing the overhead of air interface signaling, and reducing the processing complexity of the UE and the base station.

This example is mainly aimed at the timer control mode of DRB. The advantage is: reducing signaling overhead and reducing the processing complexity of the UE and the base station. The specific process is shown in Figure 3, taking the network equipment as the base station as an example and the terminal equipment as the UE (user equipment) for description:

The base station determines whether a data bearer (including data radio bearer and signaling radio bearer) uses the data replication transmission mode and related configuration information of the data replication transmission mode.

The base station determines to use the data replication transmission mode, and informs the UE of the configuration information corresponding to the data replication mode and configures the corresponding timer.

During the running of the timer, the data replication transmission mode or configuration remains unchanged.

Optionally, the duration settings of corresponding timers for different bearers can be different, which has the advantage of increasing control flexibility; or,

The duration setting of the timers of different bearers can be the same, which has the advantage of reducing UE complexity.

Optionally, the base station may notify all configuration information and configure the timer through an RRC reconfiguration message.

For example, the base station adds a new IE to the PDCP-config IE in the RRC reconfiguration message to notify the timer configuration.

For example, the base station adds an IE to the PDCP-config IE in the RRC reconfiguration IE to notify the bearer of timer information. The advantage of reusing RRC reconfiguration messages is to reuse existing messages and procedures as much as possible, reducing UE complexity.

For example: PDCP-config indicates the timer corresponding to the bearer through the following description:

"Pdcp-DuplicationTimer ENUMERATED{ms0,ms1,ms2,ms4,ms5,ms8,ms10,ms15,ms20,ms30,ms40,ms100,ms200,ms500,ms1000,spare06,spare05,spare04,spare03,spare02,spare01"

pdcp-DuplicationTimer can be a ms-level value, for example, ms1 can indicate a 1ms duration, ms2 can indicate a 2ms duration, and so on; ms0 can indicate an unconfigured timer.

The details can be as follows:

The UE receives the RRC message from the base station, configures the corresponding RLC entity according to the data replication transmission information indicated by the base station, and transmits according to the initial or default replication data transmission mode.

Optionally, the initial state of the timer can be the following:

It is bound to the initial data replication transmission method; or not bound to the initial data replication transmission method.

When binding with the initial data copy transmission mode, if the initial data copy transmission mode is deactivated, the timer will stop; if the initial data copy transmission mode is active, the timer will be started or restarted; or,

If the initial data copy transmission mode is activated, the timer is stopped; if the initial data copy transmission mode is deactivated, the timer is started or restarted.

When not bound to the initial data replication transmission mode, the timer is started/restarted when the corresponding configuration message is received; or, the timer is not started when the corresponding configuration message is received.

When the base station determines that it is necessary to change the data replication mode, the base station instructs the UE to change the data replication mode through the first information. Here, the base station notifies the change through RRC message, MAC CE, and DCI.

For example, when the base station judges that the channel quality is higher than the threshold, it uses Activation/Deactivation MAC CE to instruct the user data copy data transmission mode to deactivate. When the base station judges that the channel quality is less than the threshold, the MAC CE indicates that the user data copy data transmission mode is activated.

The UE receives a data copy mode change indication message from the base station, such as MAC CE, and activates or deactivates according to the corresponding indication information, see FIG. 4.

Step 201: When the UE receives a change indication message containing the bearer, such as an activation instruction, the UE starts or restarts the timer corresponding to the bearer; when the UE receives the change indication message but the data corresponding to the bearer is copied and transmitted When the mode indication does not change, or when the UE receives a change indication message that does not contain the bearer, the state of the timer corresponding to the bearer remains unchanged;

Step 202a: During the operation of the timer, when the UE receives a change indication message containing the bearer, the data replication transmission mode corresponding to the bearer is changed according to the indication. (Include activation instructions, deactivation instructions). Further, if it is a deactivation instruction, the timer stops.

Step 202b: During the running of the timer, when the UE receives the change indication message containing the bearer, the data replication transmission mode corresponding to the bearer remains unchanged. At this time, if the timer is running, the timer can be restarted, or no processing is performed. The advantage is to avoid frequent state changes, which brings complexity to UE processing. (Include activation instructions, deactivation instructions).

Steps

202b and 202a are mutually exclusive.

Step 203: When the timer expires, the corresponding bearer data copy transmission mode is deactivated. The advantage is to reduce the signaling overhead of the deactivation indication.

The MAC instructs the high-level PDCP replication transmission to be deactivated, and the logical channel corresponding to this DRB no longer uses the allowedServingCells restriction.

This example can be further explained in conjunction with Figure 5. After receiving the RRC reconfiguration message configured by the base station,

DRB

1 and 2 are currently in the deactivated state. When receiving a change instruction for DRB1, control DRB1 to be in the active state and turn on or restart DRB1 Corresponding timer, DRB2 remains unchanged at this time; when receiving the change instruction of DRB2, control DRB2 to be in the active state, and control to start or restart the timer of DRB2, and keep DBR1 in the active state. . When the timers of DRB1 and 2 expire, control DRB1 and DRB2 to change state to deactivated state.

Example 2 is the opposite of Example 1.

pdcp-DuplicationTimer: When the timer expires, the corresponding data replication transmission is activated. When the terminal device receives the deactivation instruction, it starts or restarts the timer corresponding to the DRB. When the timer corresponding to the DRB is started or restarted, the corresponding data copy transmission is deactivated, and the corresponding data copy transmission is deactivated during the operation of the timer r corresponding to the DRB.

Specifically, pdcp-DuplicationTimer: when the timer expires, the data replication transmission of the corresponding bearer is activated. When the terminal device receives the deactivation instruction for the corresponding bearer, it starts or restarts the timer of the corresponding bearer. When the timer of the corresponding bearer is started or restarted, the data copy transmission of the corresponding bearer is deactivated, and the data copy transmission of the corresponding bearer is deactivated during the operation of the timer corresponding to the DRB.

For example, referring to Figure 6, the RRC reconfiguration message configured by the base station is received, and

DRB

1 and 2 are currently active. When receiving a change instruction for DRB1, control DRB1 to be deactivated and start or restart the timer corresponding to DRB1 At this time, DRB2 keeps the original state unchanged; when receiving the change instruction of DRB2, control DRB2 to be in the deactivated state, and control to start or restart the timer of DRB2, and keep DBR1 in the deactivated state. When the timers of DRB1 and 2 expire, control DRB1 and DRB2 to change state to active state.

Example 3.

When there are multiple granular data replication transmission methods, different granular timer control methods can be given, such as UE-based timers, packet-based timers, QoS flow-based timers, and logical channel-based timing It is based on the cell group timer. The advantage is to increase the flexible control method of data replication and transmission.

In particular, for a granularity, for each object under this granularity, the timer duration setting can be different, which has the advantage of increasing control flexibility; or, the timer duration setting can be the same, which has the advantage of reducing UE complexity.

For example, different QoS flows in the same DRB use different timers. Since different data packets of different QoS flows correspond to different QoS, the scheduling and channel conditions during actual transmission are different, whether the data packet needs to be activated for replication transmission processing It can also be different. The advantage of using a QoS flow-based timer is that different QoS flows are not affected by each other, so as to ensure that data is transmitted in accordance with different QoS requirements and at the same time improve the effective use of system resources.

For another example, different timers are used in different cell groups corresponding to the same DRB. The premise is that the MAC entity of one cell group corresponds to more than one RLC entity. The advantage is that when there are multiple MAC entities, different MAC entities are not affected by the other party, and flexible control of replication transmission is increased. Optionally, when one CG is activated and the other CG is deactivated, one RLC entity (such as the main RLC entity) of the deactivated CG can transmit the split data packet from the DRB; or, when one CG is activated, the other When the CG is deactivated, any RLC entity of the deactivated CG does not transmit data.

The following uses a Qos flow-based timer as an example. Due to the different quality of service requirements between different QoS flows, the timer control mechanism that is fine-grained to QoS flow can prevent different QoS flows from being affected by each other, so as to ensure that data is transmitted according to different QoS requirements while improving the system Effective use of resources.

The details are shown in Figure 7, including:

The base station determines whether to use the data replication transmission mode and related configuration information of the data replication transmission mode.

The base station determines to use the data replication transmission mode and adopts the QoS flow-based control mode, and informs the UE of the configuration information corresponding to the data replication mode and the configuration timer. Among them, the base station notifies all configuration information and the configuration timer through the RRC reconfiguration message.

Optionally, the base station adds a new IE to the PDCP-config IE in the RRC reconfiguration message to notify the per QoS flow timer configuration.

For example: PDCP-config includes:

During the running of the timer, the data replication transmission mode or configuration remains unchanged. It should be pointed out that the time length settings of the timers of different QoS flows can be different, which has the advantage of increasing control flexibility; or, the time length settings of the timers of different QoS flows can be the same, which has the advantage of reducing UE complexity.

The UE receives the RRC message from the base station, configures the corresponding RLC entity according to the data replication transmission information indicated by the base station, and transmits according to the initial or default replication data transmission mode. The specifics are the same as in Example 1, and will not be repeated.

When the base station determines that it is necessary to change the data replication mode, the base station instructs the UE to change the data replication mode through the first information. The specifics are the same as in Example 1, and will not be repeated.

The UE receives the indication message for changing the data replication mode from the base station, such as MAC CE, and performs activation or deactivation according to the corresponding indication information. As shown in Figure 8, including:

Step 211: When the UE receives a change indication message containing the QoS flow of the bearer, such as an activation indication, the UE starts or restarts the timer corresponding to the bearer; when the UE receives the change indication message but the message corresponds to the bearer When the data replication transmission mode indicates no change, or when the UE receives a change indication message but the QoS flow corresponding to the bearer in the message indicates that the data replication transmission mode does not change, or when the UE receives a change indication message that does not contain the bearer The state of the timer corresponding to the bearer remains unchanged;

Step 212a: During the operation of the timer, when the UE receives a change indication message containing the QoS flow of the bearer, the data replication transmission mode corresponding to the bearer is changed according to the indication. (Include activation instructions, deactivation instructions). Further, if it is a deactivation instruction, the timer stops.

Step 212b: During the operation of the timer, when the UE receives a change indication message containing the QoS flow of the bearer, the data replication transmission mode corresponding to the bearer remains unchanged. At this time, if the timer is running, it can be restarted or unchanged. The advantage is to avoid frequent state changes, which brings complexity to UE processing. (Include activation instructions, deactivation instructions)

Steps

212b and 212a are mutually exclusive.

Step 212c: During the operation of the timer, when the UE receives a change indication message containing the bearer, such as an activation indication, the timers of all QFIs corresponding to the bearer are restarted. The advantage is to notify and control all QFIs.

Step 212d: During the operation of the timer, when the UE receives a change indication message containing the bearer, such as a deactivation indication, the timers of all QFIs corresponding to the bearer are stopped. The advantage is to notify and control all QFIs.

Steps

212c, 212d and 212a can coexist.

Steps

212c, 212d and 212b can coexist.

Step 213a: When the timer expires, the corresponding bearer QoS flow data replication transmission mode is deactivated. The advantage is to reduce the signaling overhead of the deactivation indication.

Step 213b: When the timer expires, the data replication transmission mode of the corresponding bearer QoS flow is not changed.

Steps

213b and 213a are mutually exclusive.

Figures 9 and 10 respectively illustrate activation instructions with different granularities. In Figure 9, data packets are used as the granularity, and Figure 10 is taken as the granularity of the QoS flow. Both figures are performed when the RRC reconfiguration message is received. Initial state configuration; then when receiving a change instruction for QoS Flow 1, that is, QFI 1, activate QFI1 and start the corresponding timer, when receiving a change instruction for QFI 2, activate QFI2 and start the corresponding timer. Until the timer expires, the status of

QFI

1 and 2 is changed to deactivated.

Example 4.

The reverse scheme of Example 3. The specific processing is similar to Example 3, except that it is opposite to the operation of Example 3. Refer to Figure 11, taking the QoS Flow in DRB as an example. When

QFI

1 and 2 of DRB1 are activated based on the initial configuration of the RRC reconfiguration message, the corresponding timing When receiving the change instruction for QFI 1, deactivate QFI 1 and start the corresponding timer, when receiving the change instruction for QFI, deactivate QFI 2 and start the corresponding timer; until QFI When the timers of 1 and 2 respectively expire, the states of

QFI

1 and 2 are respectively switched to the active state.

It can be seen that by adopting the above solution, corresponding time intervals are set for different objects, and the data replication and transmission mode changes of the objects are controlled based on the time interval. In this way, because the data replication transmission mode is controlled based on the time interval, it is possible to avoid the exchange of signaling between the terminal device and the network device to control the activation and deactivation processing, thereby reducing the overhead of air interface signaling, and further reducing the The interaction between signaling reduces the processing complexity of terminal equipment and network equipment. Thirdly, by adding new deactivation/activation methods, and increasing the control method of data replication transmission, the control of data replication transmission is made more flexible.

Example two

The embodiment of the present invention provides a method for controlling data replication and transmission, which is applied to a network device. As shown in FIG. 12, the method includes:

Step 31: Configure the terminal device with at least one timer for at least one object; the timer is used to provide at least one time interval for at least one object of the terminal device to copy and transmit data of the at least one object based on the time interval The change of the way is controlled.

It should also be understood that the solution provided in this embodiment uses a timer to control the time interval of the terminal device; but in fact, there may be other control methods, but the list is not exhaustive here.

time intervals

1 and 2 may be different. Of course, it can also be other granularities, which is not exhaustive here.

Correspondingly, the correspondence between timers and objects is also one-to-one correspondence, and the duration of timers of different objects, that is, the time interval may be the same or different. For example, it can correspond to the duration of different timers. Assuming that there are currently three bearers, the duration of the timer of bearer 1 can be A, and the duration of the timer of bearer 2 can be B; different bearers can also correspond to the same timer duration. For example, the duration of the timer of bearer 3 is A, which is the same as bearer 1.

The configuring at least one timer for at least one object for the terminal device further includes:

Through the RRC reconfiguration message, the configuration information notified to the terminal device, and at least one timer for at least one object.

Wherein, the configuration information may include an indication for the initial data replication transmission mode of at least one object, and the specific indication mode is not repeated here.

Correspondingly, the initial state of the timer includes:

The timer is bound to the initial data replication transmission mode; or,

The timer is not bound to the initial data replication transmission mode.

Specifically, when the initial state of the timer has a binding relationship with the initial data copy transmission mode of the timer object, it can be set to determine the initial state of the timer to start or when the initial data copy transmission is activated. Restart, when the initial data copy transmission is deactivated, it can be determined that the initial state of the timer is stopped, or the timer does not start. The opposite can also be defined accordingly. For example, when the initial data copy transmission mode is deactivated, the initial state of the timer is determined to be start or restart; when the initial data copy transmission mode is active, the initial state of the timer is determined To stop or not to start.

Further, after the at least one timer for the at least one object is configured for the terminal device, the method further includes:

Send the first information to the terminal device through one of the MAC CE, RRC message, and DCI;

Example three

The embodiment of the present invention provides a terminal device, as shown in FIG. 13, including:

The first processing unit 42 controls the change of the data replication transmission mode of at least one object based on at least one time interval for the at least one object.

The first communication unit 41 receives at least one timer configured by the network device for at least one object.

It should be pointed out that in the embodiment, the time interval is controlled by a timer, and it can also be implemented in other ways, but it is no longer limited in this embodiment.

time intervals

The first communication unit 41 obtains configuration information notified by a network device and at least one timer for at least one object through a radio resource control (RRC, Radio Resource Control) reconfiguration message.

Correspondingly, the initial state of the timer includes:

The timer is bound to the initial data replication transmission mode; or,

The timer is not bound to the initial data replication transmission mode.

When the initial state of the timer is bound to the initial data replication transmission mode, the terminal device further includes a first processing unit 42 that performs one of the following:

When the initial state of the timer is not bound to the initial data replication transmission mode, the first processing unit 42 controls to start or restart the timer when receiving the configuration message corresponding to the object; or,

Further, the first communication unit 41 obtains the first information sent by the network device through one of MAC CE, RRC message, and DCI;

Based on the first information, there are several different situations:

Case 1. The first processing unit 42 controls to start or restart the timer corresponding to the first object when the first information indicates that the first object changes the data replication transmission mode;

Case 2. The first processing unit 42 controls to keep the timer state of the first object unchanged when the first information indicates that the first object does not change the data replication transmission mode, or restarts if the timer is in the running state at this time Timer

For example, when the current data replication transmission mode of the first object is in the deactivated state, or the current data replication transmission mode is not used, the first message is received, which indicates that the first object does not change the data replication transmission mode, and the first object can be determined When an object keeps the data copy transmission mode in deactivated state, or keeps the state of not using data copy transmission, at this time, determine the timer state of the first object unchanged, or restart the timer if the timer is running at this time Device. For example, when the timer is in the running state, the timer is still in the running state, or the timer is currently in the stopped state, and the timer can be kept in the stopped state.

Case 3: The first processing unit 42 keeps the timer state of the first object unchanged when the first information does not include a message for the first object;

Case 4. The first processing unit 42, when the first object indicated by the first information changes the data replication transmission mode, and the first object contains at least one other object, control to start or restart the corresponding one of the at least one other object A timer, and/or, changing the data replication transmission mode of the first object including at least one other object; wherein the granularity of the first object and other objects are different, and the granularity of the different other objects is the same or different;

Case 5. The first processing unit 42, when the first information indicates that the changed data transmission mode of the first object is the first mode, control to start or restart the timer corresponding to the first object;

Case 6. The first processing unit 42, when the first information indicates that the change data transmission mode of the first object is the second mode, control to stop the timer corresponding to the first object; wherein, the first mode is different from the second mode ；

Case 7. The first processing unit 42, when the first information indicates that the data transmission mode of the first object is changed to the first mode, and the first object includes at least one other object, change the data transmission mode of at least one other object , And/or, control to start or restart the timer corresponding to at least one other object;

Case 8. The first processing unit 42, when the first information indicates that the data transmission mode of the first object is changed to the second mode, and the first object includes at least one other object, change the data transmission mode of at least one other object , And/or, control to stop the timer corresponding to at least one other object.

Case 1. The first processing unit 42, during the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, perform the data replication transmission mode of the first object according to the first information Change and control the timer of the first object to stop;

Case 2. The first processing unit 42, during the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, and the first object contains at least one other object, according to the first object A message changes the data replication transmission mode of at least one other object, and controls the timer of at least one other object to stop;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object and at least one other object contained therein are in a data replication transmission deactivated state, and a timer controlling the first object and at least one other object contained therein is stopped.

Case 3. The first processing unit 42, during the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, perform the data replication transmission mode of the first object according to the first information Change and control the start or restart of the timer of the first object;

Case 4. The first processing unit 42, during the running of the timer of the first object, when the first information indicates that the first object changes the data replication transmission mode, and the first object contains at least one other object, according to the first object A message changes the data replication transmission mode of at least one other object, and controls the start or restart of the timer of at least one other object;

That is to say, when the timer of the first object is running, at this time, the first object can be in the active state of data replication transmission, then the first information indicates that the first object is changed to deactivate, and the control can be controlled according to the first information The first object and at least one other object contained therein are in a data replication transmission deactivated state, and the timers of the first object and at least one other object contained therein are controlled to start or restart.

Case 5. The first processing unit 42 keeps the data copy transmission mode of the first object unchanged when receiving the first information for the first object during the running of the timer of the first object.

Example 1.

This example is mainly aimed at the timer control mode of DRB. The advantage is: reducing signaling overhead and reducing the processing complexity of the UE and the base station.

This example can be further illustrated in conjunction with Fig. 5. The first communication unit receives the RRC reconfiguration message configured by the base station, and DRBs 1 and 2 are currently in the deactivated state. When receiving a change indication for DRB1, the first processing unit 42: Control DRB1 to be active and start or restart the timer corresponding to DRB1. At this time, DRB2 remains unchanged; when receiving the DRB2 change instruction, control DRB2 to be active, and control to start or restart the timer of DRB2, Keep DBR1 in the active state at this time. When the timers of DRB1 and 2 expire, control DRB1 and DRB2 to change state to deactivated state.

Example 2 is the opposite of Example 1.

pdcp-DuplicationTimer: When the timer expires, the corresponding data replication transmission is activated. When the terminal device receives the deactivation instruction, it starts or restarts the timer corresponding to the DRB. When the timer corresponding to the DRB is started or restarted, the corresponding data copy transmission is deactivated, and the corresponding data copy transmission is deactivated during the operation of the timer corresponding to the DRB.

DRB

1, 2 are currently in the active state. When receiving the change instruction for DRB1, control DRB1 to be in the deactivated state and start or restart the timer corresponding to DRB1 At this time, DRB2 keeps the original state unchanged; when receiving the change instruction of DRB2, control DRB2 to be in the deactivated state, and control to start or restart the timer of DRB2, and keep DBR1 in the deactivated state. When the timers of DRB1 and 2 expire, control DRB1 and DRB2 to change state to active state.

Example 3.

QFI

1 and 2 is changed to deactivated.

Example 4.

QFI

1 and 2 are respectively switched to the active state.
