Description

Data transmission control method, terminal, network device, apparatus and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a data transmission control method, a terminal, a network device, an apparatus, and a storage medium.

Background

The New air interface (NR) system designs 3 Radio Resource Control (RRC) states: an IDLE (RRC IDLE) state, a CONNECTED (RRC CONNECTED) state, and an inactive (RRC INACTIVE) state. In the RRC CONNECTED state, an air interface between a Terminal (also called User Equipment (UE)) and a radio network is available at any time; but the air interface between the UE and the wireless network is disconnected in the RRC IDLE state; RRC INACTIVE state, the air interface between the UE and the wireless network is pending and needs to be resumed for use.

In the related scheme, when the UE is at RRC INACTIVE, the UE directly sends small data in RRC INACTIVE state by using RRC signaling (signaling), which is an RRC recovery request message, and the UE puts an uplink (Up Link, UL) small data packet and the RRC recovery request message together and sends the packet to the network side through a UL message.

However, the procedure of transmitting small packets by the UE in the RRC INACTIVE state is not as required by the existing RRC recovery procedure. The UE may need to send the first small data packet even the subsequent small data packets when not entering the RRC CONNECTED state, and send the first small data packet and the subsequent small data packets together, which causes the terminal to frequently enter the RRC CONNECTED state, wastes signaling resources, and increases power consumption.

Detailed Description

Small Data (Small Data) in the field of Communication refers to Data with a packet size smaller than a preset threshold, and is often used in large-scale Machine Type Communication (mtc) and high-reliability and Low-Latency Communication (URLLC).

The NR system has 3 RRC states designed: RRC IDLE state, RRC CONNECTED state, and RRC INACTIVE state. When in the RRC CONNECTED state, the air interface between the UE and the wireless network is available at any time; but the air interface between the UE and the wireless network is disconnected in the RRC IDLE state; RRC INACTIVE state, the air interface between the UE and the wireless network is pending and needs to be resumed for use.

If the direct small data transmission is allowed when the UE is in the RRC INACTIVE state, the UE is prevented from frequently entering the RRC connection state, and the signaling overhead can be reduced. But how to control the small data transmission process in the RRC INACTIVE state is not currently discussed.

In the current candidate scheme, RRC signaling (signaling) mode transmission may be adopted, and no (w/o) RRC signaling mode transmission may be adopted.

In order to solve the problem of directly sending small data in an RRC inactive state by using an RRC signaling method, a currently basic consensus is that the RRC message is an RRC recovery request message, and the UE puts a UL small data packet and the RRC recovery request message together and sends the UL small data packet and the RRC recovery request message to a network side through one UL message.

Fig. 1 is a typical flow diagram of an RRC recovery procedure, which may be employed when a UE in an RRC inactive state wants to recover an RRC connection that has been suspended, as shown in fig. 1. Through this process, a Signaling Radio Bearer (SRB), a Data Radio Bearer (DRB), or an update of a Notification Area (RAN based Notification Area, RNA) of the Radio access network may be recovered, and of course, the network side may also reject the recovery request, or release the terminal to return to the idle state, or release the terminal to return to the RRC INACTIVE state. If the network side can not find the context of the terminal, a new connection can be established for the terminal through a rollback process.

When the UE sends the RRC recovery request message, it starts a timer T319.

The UE stops T319 if: receiving a response from the network side, wherein the response comprises an RRC recovery (Resume) message, an RRC establishment (Setup) message, an RRC Release (Release) message or an RRC Reject (Reject) message; cell reselection occurs; or receiving an upper layer indication to abort the connection recovery procedure.

If T319 times out, the UE considers the RRC recovery procedure to fail.

Through T319, the RRC recovery procedure is controlled.

However, the procedure for UE to transmit small data packets in the inactive state is not as required by the existing RRC recovery procedure. The UE may need to send the first small packet and even the subsequent small packets without entering the RRC connected state. Special treatment may be required for the inactive state transmission of small data packets. The two are sent together, so that the terminal frequently enters an RRC CONNECTED state, signaling resources are wasted, and power consumption is increased.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to solve the above technical problem, an embodiment of the present application configures a timer dedicated for transmitting small data in an inactive state, for controlling a transmission process of small data in an inactive state.

Fig. 2 is a schematic diagram of a data transmission control method according to an embodiment of the present application, and as shown in fig. 2, an execution subject of the data transmission control method according to the embodiment of the present application may be a terminal. The method comprises the following steps:

step 201, obtaining configuration information indicated by network equipment; the configuration information includes a dedicated timer for controlling data transmission.

Specifically, before the UE sends small data, the UE first needs to obtain configuration information indicated by the network device, where the configuration information includes a dedicated timer for controlling data transmission.

The network device may be a base station or an air interface control network element.

The network device may indicate the configuration information to the UE through dedicated information, for example, the configuration information may be indicated to the UE using an RRC release message.

The network device may indicate the configuration information to the UE through a broadcast message.

Step 202, setting the special timer to control the data transmission process in the inactive state.

Specifically, after acquiring the configuration information indicated by the network device, the UE determines the dedicated timer.

The dedicated timer is then set to control the data transfer process in the inactive state.

For example, the dedicated timer may continue to use the timer T319, but the value of the timing duration thereof is a value dedicated to the inactive state small data transmission process, and the value is greater than the timing duration in the RRC recovery process performed by the terminal when data is not transmitted (i.e. only the RRC recovery process is performed under normal circumstances). By reconfiguring the timing duration of the timer T319, the duration of waiting for the RRC response message by the UE is directly prolonged.

The special timer may also be a newly added timer T1 different from the timer T319, and the special timer is used to extend the duration for the UE to wait for the RRC response message, and when the timer T319 expires, the UE continues to wait for the RRC response message without considering that the RRC recovery procedure fails or the small data transmission procedure in the inactive state fails.

The dedicated timer may also be a newly added timer T2 different from the timer T319 for stopping the transmission of subsequent upstream data packets when the timer duration is reached.

According to the data transmission control method provided by the embodiment of the application, the small data transmission process in the non-activated state is controlled by configuring the timer special for small data transmission in the non-activated state, the process of transmitting the small data packet in the non-activated state is distinguished from the general RRC recovery process, the normal operation of the process of directly transmitting the small data in the non-activated state is ensured, the terminal is prevented from frequently entering the connected state, and the signaling overhead and the power consumption are reduced.

Based on any of the above embodiments, the dedicated timer is the timer T319 in the RRC recovery process of radio resource control, and the timing duration of the dedicated timer is greater than the target duration, where the target duration is the timing duration in the RRC recovery process performed by the terminal when data is not transmitted.

Specifically, in the embodiment of the present application, the dedicated timer continues to use the timer T319, but the value of the timing duration of the dedicated timer is a value dedicated to the inactive state small data transmission process, and the value is greater than the timing duration of the RRC recovery process that the terminal only performs alone when data is not transmitted. By reconfiguring the timing duration of the timer T319, the duration of waiting for the RRC response message by the UE is directly prolonged.

For example, the timing duration of the original timer T319 is 10ms, and in the embodiment of the present application, the timing duration of the timer T319 is reconfigured by 15ms, so as to directly extend the duration of the UE waiting for the RRC response message.

Optionally, the network side configures to use DRBs (possibly one or more) corresponding to the timer T319.

The UE receives the configuration and stores it.

According to the data transmission control method provided by the embodiment of the application, the time length of the UE for waiting for the RRC response message is directly prolonged by reconfiguring the timing time length of the timer T319, so that the transmission time length of the small data is prolonged, the control on the small data transmission is realized, the method is simple and practical, and the complexity of system implementation is reduced.

Based on any of the above embodiments, the dedicated timer is a timer different from the timer T319, and the dedicated timer is used to extend the duration for the terminal UE to wait for the RRC response message;

Specifically, in the embodiment of the present application, the dedicated timer is a newly added timer T1 different from the timer T319, and the dedicated timer is used to extend the duration of waiting for the RRC response message by the UE, and when the timer T319 times out, the UE continues to wait for the RRC response message without considering that the RRC recovery procedure fails or the small data transmission procedure in the inactive state fails.

For example, the timing duration of the timer T319 is 10ms, the timing duration of the dedicated timer T1 is configured to be 15ms, the timer T319 and the timer T1 are started simultaneously, and when the timer T319 times out, the UE continues to wait for an RRC response message without considering that an RRC recovery procedure fails or a small data transmission procedure in an inactive state fails.

For example, the timing duration of the timer T319 is 10ms, the timing duration of the dedicated timer T1 is configured as 5ms, when the timer T319 times out, the terminal starts the timer T1 and continues to wait for the RRC response message, and does not consider that the RRC recovery procedure fails or the small data transmission procedure in the inactive state fails.

Optionally, the network side configuration uses DRBs (possibly one or more) corresponding to the dedicated timer T1.

According to the data transmission control method provided by the embodiment of the application, the timer T1 different from the timer T319 is newly added to specially control the transmission of small data, so that the signaling overhead and the power consumption are further reduced.

Based on any of the above embodiments, the dedicated timer is a timer different from the timer T319, and the dedicated timer is configured to stop sending the subsequent uplink data packet when the timing duration is reached;

Specifically, in the embodiment of the present application, the dedicated timer is a newly added timer T2 different from the timer T319, and the timing duration of the dedicated timer is smaller than the timing duration of the timer T319, so as to stop sending the subsequent uplink data packet when the timing duration is reached.

And configuring a special timer T2 for the condition that the UE has more small data to be sent, wherein the timing duration of the special timer T2 is less than the timing duration of the timer T319, and the special timer T2 is used for stopping sending the subsequent uplink data packet when the timing duration is reached. Thereby avoiding sending small data all the time.

For example, the timing duration of the timer T319 is 10ms, the timing duration of the dedicated timer T2 is configured to be 8ms, the timer T319 and the timer T2 are started simultaneously, and when the timer T2 times out, the UE stops transmitting the subsequent uplink data packet. Thereby avoiding sending small data all the time.

Optionally, the network side configuration uses DRBs (possibly one or more) corresponding to the dedicated timer T2.

According to the data transmission control method provided by the embodiment of the application, the timer T2 different from the timer T319 is newly added and is used for stopping sending the subsequent uplink data packet when the timing duration is reached, so that the reliability of the system is prevented from being reduced due to the fact that small data are sent all the time, and the reliability of the system is improved.

Based on any of the above embodiments, during the operation of the dedicated timer, if an RRC response message is received, or an indication message for terminating an RRC recovery procedure is received, or cell reselection occurs, the dedicated timer is terminated.

Specifically, in the embodiment of the present application, for the case where the dedicated timer continues to use the timer T319, inheriting the behavior in the existing protocol, the UE stops the timer T319 in the following cases: receiving RRC response of a network side; cell reselection occurs; or receiving indication information for terminating the RRC recovery procedure.

The RRC response of the network side comprises a RRCResume message, a RRCSetup message, a RRCRelease message and a RRCRreject message.

The indication information for terminating the RRC recovery procedure may be indicated by the upper layer or may be indicated by the network side.

According to the data transmission control method provided by the embodiment of the application, during the running period of the special timer, if the preset condition is met, the special timer is stopped, and the timer does not need to be waited for overtime, so that the system time delay can be reduced.

Based on any of the above embodiments, when the dedicated timer expires, it is determined that the RRC recovery procedure fails, or the data transmission procedure in the inactive state fails.

Specifically, in the embodiment of the present application, for a situation that the dedicated timer continues to use the timer T319, a value of a timing duration of the timer T319 is a value dedicated to an inactive state small data transmission process, and the value is greater than the timing duration in an RRC recovery process performed by the terminal when data is not transmitted. By reconfiguring the timing duration of the timer T319, the duration of waiting for the RRC response message by the UE is directly prolonged.

When the dedicated timer is overtime, it is determined that the RRC recovery procedure fails or the data transmission procedure in the inactive state fails.

For example, the timing duration of the original timer T319 is 10ms, and in the embodiment of the present application, the timing duration of the timer T319 is reconfigured by 15ms, so as to directly extend the duration of the UE waiting for the RRC response message. And when the special timer exceeds the timing duration of 15ms, determining that the RRC recovery process fails or the data transmission process in the non-activated state fails.

According to the data transmission control method provided by the embodiment of the application, aiming at the condition that the special timer continues to use the timer T319, when the special timer is overtime, the RRC recovery process is determined to fail, or the data transmission process in the non-activated state fails, so that the transmission time of small data is prolonged, the control on small data transmission is realized, the method is simple and practical, and the complexity of system implementation is reduced.

According to any of the above embodiments, when the timer T319 times out, one or more of the following operations are performed:

stopping monitoring uplink scheduling;

Specifically, in the embodiment of the present application, the dedicated timer is a newly added timer T1 different from the timer T319, and is used for the case of extending the duration of waiting for the RRC response message by the UE.

When the timer T319 times out, the UE continues to wait for the RRC response message, and does not consider that the RRC recovery process fails or the small data transmission process in the non-activated state fails.

Meanwhile, optionally, the RRC layer of the UE notifies the MAC layer, and triggers the MAC layer to perform one or more of the following operations:

and stopping sending other uplink media access control protocol data units (or uplink data packets) except the first uplink media access control protocol data unit (or uplink data packet).

According to the data transmission control method provided by the embodiment of the application, the timer T1 different from the timer T319 is newly added, and when the timer T319 is overtime, the corresponding operation is stopped, so that the reliability of the system is prevented from being reduced, and the reliability of the system is improved.

Based on any embodiment, when the dedicated timer times out, one or more of the following operations are performed:

When the timer T2 times out, the RRC layer of the UE notifies the MAC layer, triggering the MAC layer to perform one or more of the following operations:

stopping monitoring uplink (dynamic) scheduling;

stopping sending the uplink media access control protocol data unit;

Based on any of the above embodiments, when the dedicated timer expires, one or more of the following operations are performed:

resuming monitoring uplink scheduling;

If the UE side receives an RRC response message fed back by the network side during the operation of the dedicated timer T1, or a cell reselection occurs, or receives an upper layer indication to abort the connection recovery procedure, and the dedicated timer T1 expires, the RRC of the UE notifies the MAC layer, and triggers the MAC layer to perform one or more of the following operations:

resuming listening to the uplink (dynamic) scheduling;

Optionally, the MAC layer performs the above operations only when the UE receives an RRC message fed back by the network side, or only when the UE receives an rrccresult message and an RRCSetup message fed back by the network side.

According to the data transmission control method provided by the embodiment of the application, the timer T1 different from the timer T319 is newly added, when the timer T319 is overtime, the corresponding operation is stopped, and when the special timer is terminated, the related operation is recovered, so that the reliability of the system is prevented from being reduced, and the reliability of the system is improved.

Based on any of the above embodiments, when the timer T319 is terminated, or an RRC response message is received, or an RRC recovery message is received, or an RRC setup message is received, one or more of the following operations are performed:

When the timer T2 times out, the UE stops performing the relevant operation.

If the UE side receives an RRC response message fed back by the network side during the running of the timer T319 after the dedicated timer T2 expires, or a cell reselection occurs, or receives an upper layer indication to abort the connection recovery procedure, and when the timer T319 expires, the UE RRC notifies the MAC layer, and triggers the MAC layer to perform one or more of the following operations:

Or the timer T319 has been extended to 15ms (only T319 in the RRC recovery procedure performed separately is 10ms), the timing duration of the dedicated timer T2 is configured to be 12ms, and the timers T319 and T2 are started simultaneously. When T2 times out, the UE stops sending subsequent uplink packets. Thereby avoiding sending small data all the time.
