The invention discloses a control method for data replication and transmission, a terminal device, a network device, a chip, a computer readable storage medium, a computer program product and a computer program, wherein the method comprises the following steps: the change of the data copy transmission mode of the at least one object is controlled based on at least one time interval for the at least one object.

Description

Control method for data replication and transmission, terminal equipment and network equipment

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to a control method for data replication and transmission, a terminal device, a network device, a computer storage medium, a chip, a computer readable storage medium, a computer program product, and a computer program.

Background

For data duplication transmission, the uplink PDCP data duplication function may be configured based on the DRB, that is, different DRBs may or may not be configured to support PDCP duplication data transmission. The configuration mode of corresponding data copying or the activation/deactivation mode is also carried out based on the bearing.

However, release16 puts a higher demand on the data replication and transmission characteristics, and the system can implement a more flexible and efficient data replication manner. In the prior art, only an activation/deactivation MAC CE can be used to control the data copy transmission to be turned on or off. The disadvantage of the prior art is that this manner based on MAC CE indication brings a large amount of overhead for air interface signaling in the flexible changing scenario required by R16 data multiplexing, which needs to be avoided by the 5G system.

In addition, in the prior art, the configuration of the data copy 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 bearer level based configuration or activation/deactivation indication increases the processing complexity of the terminal device and the network device, increases the air interface overhead, and also has a state where activation/deactivation cannot be controlled more flexibly.

Embodiment 1,

The embodiment of the invention provides a control method for data replication and transmission, which is applied to terminal equipment, as shown in fig. 2, and comprises the following steps:

step 21: the change of the data copy transmission mode of the at least one object is controlled based on at least one time interval for the at least one object.

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

It should be noted that in the embodiment, the time interval is controlled by a timer, but may be implemented in other manners, which are not limited in this embodiment.

Before performing step 21, the method may further include: the receiving network device configures at least one timer for at least one object.

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

The time intervals may be in a one-to-one correspondence with the objects, for example, the description is given by taking the bearer as granularity, the time interval 1 corresponds to the bearer 1, the time interval 2 corresponds to the bearer 2, and the

time intervals

1 and 2 may be different. Of course, other granularities are possible and are not intended to be exhaustive.

Correspondingly, the corresponding relation between the timers and the objects is also one-to-one correspondence, and the time durations of the timers of different objects, namely the time intervals, can be the same or different. For example, for different bearers, the duration of different timers may be corresponding, and assuming that there are three bearers currently, the duration of timer 1 of bearer 1 may be a and the duration of timer 2 of bearer 2 is B; the same timer duration may also be corresponding to different bearers, for example, the duration of timer 3 of bearer 3 is a, which is the same as bearer 1.

Other granularities are also the same, but are not exhaustive in this embodiment.

The bearers may be data bearers (DRB, data Resource Bearer) and/or signaling bearers (SRB, signal Resource Bearer) in this embodiment.

In summary, this embodiment can introduce timers for different bearers, such as DRBs. In this way, a new deactivation mode can be added for data replication transmission, so that the air interface signaling overhead caused by activation/deactivation signaling interaction is reduced.

In addition, more timer control modes with different granularities, such as a timer based on DRB, a timer based on a logic channel, a timer based on a data packet and a timer based on QoS flow are introduced. Thereby increasing the flexible control manner of data copy transmission.

Further, after the timer provided by the application times out, the data replication transmission mode of the corresponding object with the corresponding granularity is deactivated/activated, that is, the state that the corresponding object uses data replication transmission or does not use data replication transmission. Specifically, when a certain object is in an activated state or a state of using data copy transmission, if the timer expires, the object may be controlled to be in a deactivated state or a state of not using data copy transmission. Or conversely, when a certain object is in a deactivated state or a state of not using data copy transmission, if the timer is overtime, the object can be controlled to be in an activated state or a state of using data copy transmission.

The receiving network device configures at least one timer for at least one object, further comprising:

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

The configuration information may be information provided in the prior art, where an indication may be included in an initial data copy transmission manner for at least one object, and a specific indication manner is not described herein.

The at least one object may be an object with the same granularity, and may be an object with different granularity. For example, at least one timer may be configured for at least one DRB, or at least one timer may be configured for at least one DRB, and at least one CG, respectively, although other situations are possible and are not exhaustive.

Further, the initial state of the timer may be a stop state or an on state; i.e. in a stopped state when the initial state of the timer is in a stopped state, i.e. when the timer is configured to the terminal device, but may of course also be in an on state, i.e. in an on state as soon as the timer is configured to the terminal device.

Correspondingly, the initial state of the timer comprises:

the timer is bound with an initial data copying transmission mode; or alternatively, the process may be performed,

the timer is not bound with the initial data copying transmission mode.

When the initial state of the timer is bound to the initial data copy transmission mode, the method further comprises one of the following steps:

when the initial data copying transmission mode of the object is deactivation, controlling a timer to stop;

when the initial data copying transmission mode of the object is activated, a timer is controlled to be started or restarted;

when the initial data copying transmission mode of the object is activated, controlling a timer to stop;

when the initial data copying transmission mode of the object is deactivation, the timer is controlled to start or restart.

Specifically, when the initial state of the timer has a binding relationship with the initial data copy transmission mode of the object of the timer, it may be set that the initial state of the timer is determined to be started or restarted when the initial data copy transmission is activated, and the initial state of the timer may be determined to be stopped or the timer is not started when the initial data copy transmission is deactivated. Conversely, the method may be defined accordingly, for example, when the initial data replication transmission mode is deactivated, the initial state of the timer is determined to be started or restarted, and when the initial data replication transmission mode is activated, the initial state of the timer is determined to be stopped or not started.

When the initial state of the timer is not bound with the initial data copying transmission mode, the method further comprises the following steps:

when receiving the configuration message corresponding to the object, controlling to start or restart the timer; or alternatively, the process may be performed,

when receiving a configuration message corresponding to the object, controlling not to start a timer; or alternatively, the process may be performed,

and when receiving a special message corresponding to the object, controlling to start or restart the timer, wherein the special message is used for starting or restarting the timer in a state that the timer is stopped by default.

In this case, the initial state of the timer is not limited by the initial data copy transmission manner of the object, but it is determined whether to start or restart the timer according to the configuration message or the dedicated message, or whether the initial state of the timer is not started.

The dedicated message may be carried by other information and sent to the terminal device, for example, may be carried by one of MAC CE, RRC or DCI, where when the dedicated message may indicate that the timer for a certain object is stopped, the initial state of the timer is controlled to be started or restarted according to the dedicated message; the dedicated message may include identification information of the object and specific message content indicating that the timer is started or restarted, although other content may be included, which is not exhaustive.

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

acquiring first information sent by network equipment through one of MAC CE, RRC message and DCI;

the first information is used for indicating a data copy transmission mode of an object to be changed or not to be changed.

That is, after configuring the timer, the network device may also send a change instruction for the data copy transmission mode to the terminal device.

Based on the first information, the following several different cases may be provided:

in the case 1, when the first information indicates that the first object changes the data copy transmission mode, controlling to start or restart a timer corresponding to the first object;

for example, when the current data replication and transmission mode of the first object is in a deactivated state or is in a state of not using data replication and transmission, the first information is received, the information indicates that the first object changes the data replication and transmission mode, and it can be determined that the first object is changed to an activated state or a state of using data replication and transmission by the first message, and at this time, it is determined to start or restart the timer of the first object.

Of course, there may be an opposite processing manner, for example, when the current data replication and transmission manner of the first object is in an active state, or when the current data replication and transmission manner is in a state of using data replication and transmission, the first information is received, and indicates that the first object changes the data replication and transmission manner, it may be determined that the first object is changed to a deactivated state by the first message, or a state of not using data replication and transmission is performed, and at this time, it is determined that the timer of the first object is started or restarted.

When the method is specifically used, which processing mode is adopted can be determined according to actual conditions, and the method is not limited in the embodiment.

2, when the first information indicates that the first object does not change the data copying transmission mode, controlling to keep the timer state of the first object unchanged, or restarting the timer if the timer is in an operation state at the moment;

for example, when the current data replication and transmission mode of the first object is in a deactivated state or is in a state of not using data replication and transmission, the first information is received, and the information indicates that the first object does not change the data replication and transmission mode, it can be determined that the first object keeps the data replication and transmission mode in the deactivated state or keeps the state of not using data replication and transmission, at this time, it is determined that the timer state of the first object is unchanged, or if the timer is in an operating state at this time, the timer is restarted; for example, when the timer is in the running state, the timer is kept still in the running state, or the timer is currently in the stop state, and the timer can be kept still in the stop state.

Of course, the opposite processing manner may also exist, and will not be described in detail.

Case 3, when the first information does not contain a message for the first object, controlling to keep the timer state of the first object unchanged;

in other words, if the first information is not a change instruction for the first object, the timer state of the first object is kept unchanged, for example, the timer state is kept in the running state, and the timer state is kept in the stopped state.

4, when the first information indicates that the first object changes the data replication transmission mode and the first object includes at least one other object, controlling to start or restart a timer corresponding to the at least one other object and/or changing the data replication transmission mode of the first object including the at least one other object; wherein the granularity of the first object is different from that of other objects, and the granularity of the different other objects is the same or different;

in this case, the first object may include other objects with smaller granularity, for example, when the first object is a terminal device, the other objects with smaller granularity may be DRBs, qoS flows, logical channels, etc., and then the other objects, for example, DRBs, and at least one timer corresponding to the QoS flows and the logical channels, may be started or restarted; still further, when the data replication transmission of the other objects is in the activated state, and the first information for changing the data replication transmission mode of the first object is received, at least one other object included in the first object may be changed to the deactivated state, and/or a timer of the other object may be controlled to be started or restarted. Antisense vice versa, only will not be repeated.

For another example, the change is directed to the bearer, and then a timer of each logical channel, cell group, packet, and QoS flow included in the bearer is started or restarted, and/or a duplicate data transmission of each logical channel, cell group, packet, and QoS flow is changed. Taking a logic channel as an example for explanation, the data copy transmission of the logic channel is in a deactivated state, after receiving the first information, the data copy transmission mode of the logic channel is controlled to be in an activated state, and a timer corresponding to the logic channel is started or restarted; vice versa, is not exhaustive. In addition, the processing manners of the other objects may be the same, and will not be described in detail.

5, when the first information indicates that the changed data transmission mode of the first object is the first mode, controlling to start or restart a timer corresponding to the first object;

a case 6, when the first information indicates that the changed data transmission mode of the first object is the second mode, controlling to stop the timer corresponding to the first object; wherein the first mode is different from the second mode;

the description is given for cases 5 and 6, where the first mode is different from the second mode, for example, when the first mode is activated, the second mode is deactivated; the first mode is deactivated and the second mode is activated.

Taking the first mode as an example for activation, that is, when the first object (for example, DRB) is in the current (or original) deactivated state, the first object is controlled to be changed into the first mode, that is, the activated state by receiving the first information, and at this time, the timer of the first object can be controlled to be started or restarted;

the timer may be in an active state when the first object, such as a DRB, is currently in an active state, but may be in a stopped state, where the data copy transmission mode of the first object is controlled to be deactivated based on the first information and the timer is controlled to be in a stopped state as long as the data copy transmission mode is received to indicate that the first object is changed to be in a deactivated state.

It should be understood that the foregoing only provides an explanation of one scenario, and conversely, the first mode is deactivation and the second mode is activation, which may be the same as the foregoing, but the control mode of the timer is opposite, which is not repeated herein.

In case 7, when the first information indicates that the changed data transmission mode of the first object is the first mode and the first object includes at least one other object, the data transmission mode of the at least one other object is changed, and/or the timer corresponding to the at least one other object is controlled to be started or restarted;

In case 8, when the first information indicates that the changed data transmission mode of the first object is the second mode and the first object includes at least one other object, the data transmission mode of the at least one other object is changed, and/or the timer corresponding to the at least one other object is controlled to be stopped.

Cases 7 and 8 are also described together, and the first and second aspects may be the same as cases 5 and 6, and will not be described again. Further, the cases 7 and 8 are different from the cases 5 and 6 in that, for the first information of the first object, the timer of at least one other object included in the first object can be controlled, for example, when the first object is a DRB, the other object may be at least one logical channel included in the DRB, and when the first information of the first object is changed to a first mode, for example, an active state, the timer corresponding to the at least one other object, that is, the at least one logical channel, can be controlled to be started or restarted. Of course, the timer of at least one other object may be controlled to start or restart on the contrary, i.e. when the first mode is deactivation.

In addition, when the first object is a DRB, the timer that receives the first information about the first object is changed to the second mode, i.e., the deactivated state, and at least one logical channel (i.e., at least one other object) may be controlled to stop. The other way around is also possible, for example, the second mode is an active state, and the timer of at least one other object can be controlled to stop.

During the time that the timer of the first object is running, processing may be based on several conditions:

in case 1, when first information indicates that a first object changes a data copy transmission mode during the running of a timer of the first object, changing the data copy transmission mode of the first object according to the first information, and controlling the timer of the first object to stop;

that is, when the timer of the first object is running and at this time, the first object may be in the data copy transmission activation state, and then the first information indicates that the first object is changed to the deactivation state, the first object may be controlled to be in the data copy transmission deactivation state according to the first information, and the timer of the first object may be controlled to be stopped.

Of course, the same is true, for example, when the timer of the first object runs, and at this time, the first object may be in a data copy transmission deactivated state, and when the first information indicates that the first object is changed to be active, the first object may be controlled to be in a data copy transmission activated state according to the first information, and the timer of the first object is controlled to be stopped.

In 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 and transmission mode, and the first object includes at least one other object, changing the data replication and transmission mode of the at least one other object according to the first information, and/or controlling the timer of the at least one other object to stop;

That is, when the timer of the first object is running, and at this time, the first object may be in a data copy transmission activation state, and then the first information indicates that the first object is changed to be deactivated, the first object and at least one other object included therein may be controlled to be in the data copy transmission deactivation state according to the first information, and/or the timer controlling the first object and at least one other object included therein may be stopped.

Of course, the same is true, for example, when the timer of the first object is running, and at this time, the first object may be in a data copy transmission deactivated state, and when the first information indicates that the first object is changed to be active, the first object and at least one other object included in the first object may be controlled to be in the data copy transmission activated state according to the first information, and the timer of the first object and at least one other object included in the first object may be controlled to be stopped. For the description of the first object and other objects, reference may be made to the above description, and the description is not repeated here.

In case 3, during the running period of the timer of the first object, when the first information indicates that the first object changes the data replication and transmission mode, the data replication and transmission mode of the first object is changed according to the first information, and the timer of the first object is controlled to be started or restarted;

That is, when the timer of the first object is running and at this time, the first object may be in a data copy transmission activation state, and then the first information indicates that the first object is changed to be deactivated, the first object may be controlled to be in a data copy transmission deactivation state according to the first information, and the timer of the first object may be controlled to be started or restarted.

Of course, the same is true, for example, when the timer of the first object runs, and at this time, the first object may be in a data copy transmission deactivated state, and when the first information indicates that the first object is changed to be active, the first object may be controlled to be in a data copy transmission activated state according to the first information, and the timer of the first object may be controlled to be started or restarted.

In 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 and transmission mode, and the first object includes at least one other object, the data replication and transmission mode of the at least one other object is changed according to the first information, and/or the timer of the at least one other object is controlled to be started or restarted;

that is, when the timer of the first object is running, and at this time, the first object may be in a data copy transmission activation state, and then when the first information indicates that the first object is changed to be deactivated, the first object and at least one other object included therein may be controlled to be in a data copy transmission deactivation state according to the first information, and/or the timer of the first object and at least one other object included therein may be controlled to be started or restarted.

Of course, the same is true, for example, when the timer of the first object runs, and at this time, the first object may be in a data copy transmission deactivated state, and when the first information indicates that the first object is changed to be active, the first object and at least one other object included in the first object may be controlled to be in the data copy transmission activated state according to the first information, and the timer of the first object and at least one other object included in the first object may be controlled to be started or restarted. For the description of the first object and other objects, reference may be made to the above description, and the description is not repeated here.

And 5, during the running of the timer of the first object, when the first information aiming at the first object is received, keeping the data copying and transmitting mode of the first object unchanged.

This means that the first object is controlled based on the timer, that is, the timer of the first object is set to be in an operating period, and the data copy transmission method of the first object is not adjusted based on the first information regardless of whether the first information is received and the data copy transmission method is required to be changed.

When the timer of the first object is overtime, controlling to change the data copying and transmitting mode of the first object; or when the timer of the first object is overtime, controlling not to change the data copying transmission mode of the first object.

That is, if the timer times out, it may be controlled to change the first object from the current data copy transmission mode to another data copy transmission mode, for example, to change the first object from an active state to a deactivated state of the data copy transmission mode, and vice versa. It should be further understood that when the first object timer expires, at least one other object included in the first object may be controlled to change the data replication transmission mode, for example, when the DRB timer expires, at least one logical channel included in the first object may be controlled to change the data replication transmission mode, for example, from an active state to a deactivated state.

Of course, the change of the data copy transmission mode of the first object may not be controlled based on the timer, that is, the timer is not timed out, and the data copy transmission mode of the first object is not changed, for example, the first object remains in an activated or deactivated state. In this case, the change of the data copy transmission manner of the first object, that is, a control manner based on the instruction information, may be controlled based on the first information or other information.

The above embodiments are described in detail below in connection with a number of examples:

EXAMPLE 1,

Due to the limited air interface resources, consideration needs to be given to how to reduce the signaling overhead between the UE and the base station, which can be omitted. Therefore, a control mode of data copying transmission based on a timer is introduced, which has the advantages of adding a new deactivation/activation mode, reducing the overhead of air interface signaling and reducing the processing complexity of UE and a base station.

This example is mainly directed to a timer control manner in which the object is a DRB. The advantages are that: the signaling overhead is reduced, and the processing complexity of the UE and the base station is reduced. The specific flow is shown in fig. 3, and the description is made by taking a network device as an example of a base station and a terminal device as UE (user equipment):

the base station determines whether a data bearer (including a data radio bearer and a signaling radio bearer) uses a data copy transmission scheme and associated configuration information for the data copy transmission scheme.

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

During the timer running, the data copy transmission mode or configuration is unchanged.

Alternatively, the duration settings of the corresponding timers of different bearers may be different, which has the advantage of increasing control flexibility; or alternatively, the process may be performed,

The duration settings of the timers for different bearers may be the same, which has the advantage of reducing UE complexity.

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

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

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

For example: the corresponding timer is indicated to carry in PDCP-config by 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”

the pdcp-duplex timer may be a value in the order of ms, for example, may indicate a 1ms duration for ms1, a 2ms duration for ms2, and so on; ms0 may then characterize the unconfigured timer.

The specific method can be as follows:

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

Alternatively, the initial state of the timer may be the following:

Binding with an initial data copying transmission mode; or not bound with the original data copy transmission mode.

When binding with the initial data replication transmission mode, if the initial data replication transmission mode is deactivated, stopping the timer, and if the initial data replication transmission mode is activated, starting or restarting the timer; or alternatively, the process may be performed,

if the initial data replication transmission mode is activated, the timer is stopped, and if the initial data replication transmission mode is deactivated, the timer is started or restarted.

When the initial data copying transmission mode is not bound, starting/restarting a timer when a corresponding configuration message is received; or when the corresponding configuration message is received, the timer is not started.

When the base station judges that the data replication mode needs to be changed, the base station instructs the UE to change the data replication mode through the first information. Here, the base station notifies the change by RRC message, MAC CE, DCI.

For example, when the base station determines that the channel quality is higher than the threshold, the Activation/Deactivation MAC CE indicates that the user data copy data transmission mode is deactivated. When the base station judges that the channel quality is smaller than the threshold, the MAC CE indicates the user data to copy and activate the data transmission mode.

The UE receives a change indication message of the data replication mode from the base station, such as MAC CE, and performs activation or deactivation operation according to the corresponding indication information, see fig. 4.

Step 201, when the UE receives a change indication message containing the bearer, if the change indication message is an activation indication, the UE starts or restarts a timer corresponding to the bearer; when the UE receives the change indication message but the data copy transmission mode indication corresponding to the bearer in the message is unchanged, or when the UE receives the change indication message which does not contain the bearer, the timer state corresponding to the bearer is unchanged;

in step 202a, when the UE receives the change instruction message containing the bearer during the running of the timer, the data copy transmission mode corresponding to the bearer is changed according to the instruction. (including an activation indication, a deactivation indication). Further, if an indication of deactivation is made, the timer is stopped.

In step 202b, during the running of the timer, when the UE receives the change indication message containing the bearer, the data copy transmission mode corresponding to the bearer is unchanged. At this time, if the timer is running, the timer may be restarted or not processed, which has the advantage of avoiding frequent state changes, which may lead to complexity of UE processing. (including an activation indication, a deactivation indication).

Steps

202b and 202a are mutually exclusive.

In step 203, when the timer expires, the corresponding data copy transmission mode of the bearer is deactivated. This has the advantage of reducing the signaling overhead of the deactivation indication.

The MAC indicates that the higher layer PDCP copy transmission is deactivated, and the logical channel corresponding to the DRB is not restricted by the allowed serving cell allowedServingCells.

This example may be further described with reference to fig. 5, when an RRC reconfiguration message configured by the base station is received, DRB1 and DRB2 are currently in a deactivated state, and when a change instruction for DRB1 is received, DRB1 is controlled to be in an activated state, and a timer corresponding to DRB1 is started or restarted, where DRB2 remains unchanged; when receiving the change instruction of the DRB2, controlling the DRB2 to be in an activated state, and controlling to start or restart a timer of the DRB2, wherein the activated state of the DBR1 is kept unchanged. When the timers of

DRBs

1, 2 time out,

DRBs

1, 2 are controlled to change state to a deactivated state.

Example 2, as opposed to example 1.

The pdcp-duplex timer: and (5) activating corresponding data copying transmission after the timer is overtime. And when the terminal equipment receives the deactivation instruction, starting or restarting a timer corresponding to the DRB. When the corresponding timer of the DRB is started or restarted, the corresponding data copy transmission is deactivated and the corresponding data copy transmission is deactivated during operation of the corresponding timer r of the DRB.

Specifically, the pdcp-duplex timer: and (5) activating the data copy transmission of the corresponding bearer after the timer is overtime. And when the terminal equipment receives the deactivation instruction aiming at the corresponding bearer, starting or restarting 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 operation of the timer of the corresponding DRB.

For example, referring to fig. 6, when receiving an RRC reconfiguration message configured by a base station,

DRBs

1 and 2 are currently in an active state, and when receiving a change instruction for DRB1, controlling DRB1 to be in a deactivated state and starting or restarting a timer corresponding to DRB1, where DRB2 remains unchanged in the original state; when receiving the change indication of the DRB2, the DRB2 is controlled to be in a deactivated state, and the timer of the DRB2 is controlled to be started or restarted, so that the DBR1 is kept in the deactivated state unchanged. When the timers of

DRBs

1, 2 time out,

DRBs

1, 2 are controlled to change state to active state.

EXAMPLE 3,

When there may be multiple granularity data replication and transmission modes, different granularity timer control modes may be given, such as UE-based timers, packet-based timers, qoS flow-based timers, logical channel-based timers, and cell group-based timers. This has the advantage of increasing the flexible control means of the data copy transmission.

In particular, the time length setting of the timer can be different for each object at a granularity, which has the advantage of increasing the control flexibility; alternatively, the duration setting of its timer may be the same, which has the advantage of reducing UE complexity.

For example, different QoS flows in the same DRB use different timers, and because different data packets of different QoS flows have different QoS, the actual transmission schedule and channel conditions are different, and whether the data packets need to be activated for copy transmission can also be different. The timer based on the QoS flows has the advantages that different QoS flows are not affected mutually, so that the data is ensured to be transmitted according to different QoS requirements, and meanwhile, the effective utilization of system resources is improved.

For example, different timers are adopted in different cell groups corresponding to the same DRB, and the precondition is that one MAC entity of a cell group corresponds to more than one RLC entity. This has the advantage that when there are multiple MAC entities, the different MAC entities are not affected by each other and flexible control over duplicate transmissions is increased. Alternatively, when one CG is active and the other CG is deactivated, one RLC entity (e.g., the primary RLC entity) of the deactivated CG may transmit packets from the split of the DRB; alternatively, when one CG is active and the other CG is deactivated, none of the RLC entities of the deactivated CG transmit data.

The Qos flow based timer is described below as an example. Because the service quality requirements among different QoS flows are different, the timer control mechanism from granularity refinement to QoS flows can prevent the different QoS flows from being affected with each other, so that the system resource is effectively utilized while the data is transmitted according to different QoS requirements.

As shown in fig. 7, the method comprises:

the base station determines whether to use the data copy transmission scheme and the related configuration information of the data copy transmission scheme.

The base station determines to use the data replication transmission mode, adopts a control mode based on QoS flow, and informs the UE of configuration information corresponding to the data replication mode and a configuration timer. The base station informs all configuration information and configuration timers through an RRC reconfiguration message.

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

For example: the PDCP-config includes:

wherein, the PDCP-duplicate timerlist is used for indicating the timer list of the PDCP data duplication transmission.

Specifically, the following contents can be included:

during the timer running, the data copy transmission mode or configuration is unchanged. It should be noted that the time length setting of the timers of different Qos flows can be different, which has the advantage of increasing the control flexibility; alternatively, the time duration settings of timers of different Qos flows may be the same, which is beneficial in reducing UE complexity.

The UE receives the RRC message from the base station, configures a corresponding RLC entity according to the data copy transmission information indicated by the base station, and transmits according to an initial or default copy data transmission mode. The specific details are the same as example 1, and will not be described again.

When the base station judges that the data replication mode needs to be changed, the base station instructs the UE to change the data replication mode through the first information. The specific details are the same as example 1, and will not be described again.

And the UE receives a change indication message of the data replication mode from the base station, such as the MAC CE, and performs activation or deactivation operation according to the corresponding indication information. As shown in fig. 8, includes:

Step 211, when the UE receives the change indication message including the QoS flow of the bearer, such as an activation indication, the UE starts or restarts a timer corresponding to the bearer; when the UE receives the change indication message and the data copy transmission mode indication corresponding to the bearer in the message is unchanged, or when the UE receives the change indication message and the QoS flow data copy transmission mode indication corresponding to the bearer in the message is unchanged, or when the UE receives the change indication message not containing the bearer, the timer state corresponding to the bearer is unchanged;

in step 212a, when the UE receives the change indication message including the QoS flow of the bearer during the running of the timer, the data replication transmission mode corresponding to the bearer is changed according to the indication. (including an activation indication, a deactivation indication). Further, if the deactivation is instructed, the timer is stopped.

In step 212b, when the UE receives the change indication message including the QoS flow of the bearer during the running of the timer, the data copy transmission mode corresponding to the bearer is unchanged. At this time, if the timer is running, it may be restarted or unchanged. This has the advantage of avoiding frequent state changes, which may lead to UE processing complexity. (containing an activation indication, a deactivation indication)

Steps

212b and 212a are mutually exclusive.

In step 212c, during the timer running, when the UE receives a change indication message including the bearer, such as an activation indication, the timers of all QFI corresponding to the bearer are restarted. This has the advantage that notification controls all QFI.

In step 212d, during the timer running, when the UE receives a change indication message including the bearer, such as a deactivation indication, the timers of all QFI corresponding to the bearer are stopped. This has the advantage that notification controls all QFI.

Steps

212c,212d, and 212a may coexist.

Steps

212c,212d, and 212b may coexist.

In step 213a, when the timer expires, the data copy transmission mode of the QoS flow of the corresponding bearer is deactivated. This has the advantage of reducing the signaling overhead of the deactivation indication.

In step 213b, when the timer expires, the data copy transmission mode of the QoS flow of the corresponding bearer is not changed.

Steps

213b and 213a are mutually exclusive.

Fig. 9 and 10 are respectively illustrative examples of change indication representative activation indication with different granularity, in fig. 9, the granularity is given to a data packet, and in fig. 10, the granularity is given to QoS flow; in both figures, the configuration of the initial state is carried out after the RRC reconfiguration message is received; then, when a change instruction for QFI1, which is QFI1, is received, QFI1 is activated and a corresponding timer is started, and when a change instruction for QFI2 is received, QFI2 is activated and a corresponding timer is started. Until the timer times out, the state of QFI1, 2 is changed to deactivated.

EXAMPLE 4,

The reverse scheme of example 3. The specific process is similar to example 3, except that, contrary to the operation of example 3, referring to fig. 11, taking QoS Flow in DRB as an example, when

QFI

1, 2 of DRB1 is in an active state based on initial configuration of RRC reconfiguration message, the corresponding timer is in a stopped state; when receiving the change instruction for QFI 1, deactivating QFI 1 and starting a corresponding timer, and when receiving the change instruction for QFI, deactivating QFI 2 and starting a corresponding timer; and the state of the QFI 1 and the state of the QFI 2 are respectively switched to the activated state until the timers of the QFI 1 and the QFI 2 respectively time out.

Embodiment II,

The embodiment of the invention provides a control method for data replication and transmission, which is applied to network equipment, as shown in fig. 12, and comprises the following steps:

step 31: configuring at least one timer for at least one object for the terminal device; the timer is used for providing at least one time interval for at least one object of the terminal equipment so as to control the change of the data replication transmission mode of the at least one object based on the time interval.

It should also be understood that the scheme provided in this embodiment controls the time interval of the terminal device with a timer; however, in practice, other ways of control are possible, but are not exhaustive.

time intervals

Correspondingly, the corresponding relation between the timers and the objects is also one-to-one correspondence, and the time durations of the timers of different objects, namely the time intervals, can be the same or different. For example, the duration of different timers may be corresponding, and assuming that there are three bearers currently, the duration of the timer of the bearer 1 may be a and the duration of the timer of the bearer 2 is B; the same timer duration may also be corresponding to different bearers, for example, the duration of the timer for bearer 3 is a, which is the same as bearer 1.

In addition, since more timer control modes with different granularities, such as a timer based on DRB, a timer based on a logic channel, a timer based on a data packet and a timer based on QoS flow are introduced. Thereby increasing the flexible control manner of data copy transmission.

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

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

The configuration information may include an indication of an initial data copy transmission manner for at least one object, and a specific indication manner is not described herein.

Correspondingly, the initial state of the timer comprises:

the timer is not bound with the initial data copying transmission mode.

Further, after the configuring the at least one timer for the at least one object for the terminal device, the method further comprises:

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

time intervals

Correspondingly, the initial state of the timer comprises:

the timer is not bound with the initial data copying transmission mode.

When the initial state of the timer is bound to the initial data copy 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 alternatively, the process may be performed,

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

in 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 copy transmission mode;

In 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 copy transmission mode, or restarts the timer if the timer is in the running state at this time;

for example, when the current data replication and transmission mode of the first object is in a deactivated state or is in a state of not using data replication and transmission, the first information is received, and the information indicates that the first object does not change the data replication and transmission mode, it may be determined that the first object maintains the data replication and transmission mode in the deactivated state or maintains the state of not using data replication and transmission, at this time, it is determined that the timer state of the first object is unchanged, or if the timer is in an operating state at this time, the timer is restarted. For example, when the timer is in the running state, the timer is kept still in the running state, or the timer is currently in the stop state, and the timer can be kept still in the stop state.

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

In case 4, the first processing unit 42 controls to start or restart a timer corresponding to at least one other object when the first information indicates that the first object changes the data replication and transmission mode and the first object includes at least one other object, and/or changes the data replication and transmission mode of the first object including at least one other object; wherein the granularity of the first object is different from that of other objects, and the granularity of the different other objects is the same or different;

In case 5, the first processing unit 42 controls to start or restart the timer corresponding to the first object when the first information indicates that the changed data transmission mode of the first object is the first mode;

in case 6, the first processing unit 42 controls to stop the timer corresponding to the first object when the first information indicates that the changed data transmission mode of the first object is the second mode; wherein the first mode is different from the second mode;

In case 7, the first processing unit 42 changes the data transmission mode of at least one other object and/or controls to start or restart the timer corresponding to the at least one other object when the first information indicates that the changed data transmission mode of the first object is the first mode and the first object includes the at least one other object;

In case 8, the first processing unit 42 changes the data transmission mode of at least one other object and/or controls to stop the timer corresponding to the at least one other object when the first information indicates that the changed data transmission mode of the first object is the second mode and the first object includes the at least one other object.

in case 1, the first processing unit 42 changes the data replication and transmission mode of the first object according to the first information when the first information instructs the first object to change the data replication and transmission mode during the operation of the timer of the first object, and controls the timer of the first object to stop;

In case 2, the first processing unit 42 changes the data replication and transmission mode of at least one other object according to the first information when the first information indicates that the first object changes the data replication and transmission mode and the first object includes at least one other object during the operation of the timer of the first object, and controls the timer of the at least one other object to stop;

That is, when the timer of the first object is running and at this time, the first object may be in a data copy transmission activated state, and then the first information indicates that the first object is changed to be deactivated, the first object and at least one other object included therein may be controlled to be in the data copy transmission deactivated state according to the first information, and the timer of the first object and at least one other object included therein may be controlled to be stopped.

In case 3, the first processing unit 42 changes the data replication and transmission mode of the first object according to the first information when the first information indicates that the first object changes the data replication and transmission mode during the running of the timer of the first object, and controls the starting or restarting of the timer of the first object;

In case 4, the first processing unit 42 changes the data replication transmission mode of at least one other object according to the first information when the first information indicates that the first object changes the data replication transmission mode and the first object includes at least one other object during the running of the timer of the first object, and controls the starting or restarting of the timer of the at least one other object;

that is, when the timer of the first object is running and the first object may be in the data copy transmission activated state, the first information indicates that the first object is changed to be deactivated, the first object and at least one other object included therein may be controlled to be in the data copy transmission deactivated state according to the first information, and the timer of the first object and at least one other object included therein may be controlled to be started or restarted.

In 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 timer running of the first object.

EXAMPLE 1,

This example is mainly directed to a timer control manner in which the object is a DRB. The advantages are that: the signaling overhead is reduced, and the processing complexity of the UE and the base station is reduced.
