Description

Data stream processing method and device, communication device and storage medium technical field

The present application relates to the field of wireless communication technologies, but is not limited to the field of wireless communication technologies, and in particular, relates to a data stream processing method and apparatus, a communication device, and a storage medium.

Background technique

Mobile applications based on Artificial Intelligence (AI)/Machine Learning (ML) are increasingly computationally intensive, memory-intensive and power-hungry. At the same time, end devices often have strict energy consumption, computing and memory cost constraints. Therefore, AI/ML needs to be separated, i.e. split, on the device and the network. That is, offloading the compute-intensive, energy-intensive parts to the network endpoints, while leaving the privacy-sensitive and latency-sensitive parts on the end devices. The key to splitting AI/ML operations is to choose the best splitting mode and splitting point to keep the required resources below the upper limit of the resources available on mobile devices, and to optimize compute, storage/memory, power consumption, device and network side communication resources. Usually, when making splitting decisions, the split scheduler will take into account the computing power of the terminal and the network to make reasonable decisions to meet the requirements of AI/ML services running locally or remotely. Decisions made by the split scheduler may be business establishment decisions.

As shown in FIG. 2 , an embodiment of the present disclosure provides a data stream processing method, which is applied to the AS layer of the access layer, including:

S110: Receive a preset indication, where the preset indication is a non-access stratum NAS or AS layer indication, and S120: Respond to the preset indication.

The AS layer in the embodiments of the present disclosure may refer to the AS layer on the network side, and may also be the AS layer on the terminal side.

For example, the AS layer on the network side refers to the network protocol layer where the access device of the access network is located. The AS layer on the terminal side refers to the network protocol layer in the terminal corresponding to the access device.

The NAS layer is also a network protocol layer, and the NAS layer is higher than the AS layer. The NAS layer for the network side can generally refer to the core network to which the access network is connected.

In this embodiment of the present disclosure, a NAS indication is received, where the NAS indication may instruct to suspend one or more data streams, or to resume one or more suspended data streams.

These data streams are data streams for which service transmission has been established currently.

In one embodiment, the preset indication may be: NAS indication or AS indication.

The NAS layer issues a NAS command, which can temporarily suspend the transmission after the service transmission of the suspended data stream is established, thereby freeing more resources for the transmission and calculation of other service data. The resources here include, but are not limited to, transmission resources and/or processing resources.

The AS layer on the network side may also deliver an AS indication to the AS layer of the UE.

In the embodiment of the present disclosure, after receiving the preset instruction, the AS layer will execute the corresponding preset instruction. The response preset instructions include but are not limited to:

Suspend at least part of the data stream according to the preset instruction, and the suspended at least part of the data stream will suspend parameters and/or suspend the calculation of data contained in the data stream;

and / or,

Resume at least part of the suspended data stream according to the preset instruction, and at least part of the resumed data stream will resume operations such as transmission and/or calculation of data contained in the data stream.

For example, when the NAS layer or the AS layer on the network side detects that the network resource load rate is too high and/or there are higher priority service data to be processed, it can temporarily suspend part of the data flow through the delivery of a preset instruction. If the load rate decreases and/or after the processing of the service data of higher priority is completed, part of the data flow can be restored by issuing a preset instruction without re-establishing service transmission.

In the embodiment of the present disclosure, the service data flow for which the AS layer performs the suspend operation and/or the resume operation based on the preset instruction includes, but is not limited to, the data flow associated with AI/ML.

For example, the data flow associated with AI/ML includes but is not limited to at least one of the following:

training data stream;

application data flow;

Model data flow.

The training data stream contains: training data for AI models and /ML models.

The application data flow includes: the parameters required by the business logic that needs to be executed using the AI model and/or ML model.

The model data flow includes: parametric data describing the AI model and/or the ML model itself.

For example, an AI model usually includes a neural network with various network structures; the model data flow may include: hyperparameters of the neural network and/or weights of each network node, etc.

If each terminal collects data to form a data stream and reports it to the network side, when the AI model and/or ML model is trained by the equipment on the network side, it may be equivalent to the traffic data such as calls or Internet surfing in related technologies. A service data flow that has a long duration and/or a large amount of data and consumes computing resources on the network side.

Therefore, the remote training of the AI model and/or ML model is performed on the network side, and during the training process of the sample data provided by the terminal side, if there are other services that need to be transmitted, and the current network congestion phenomenon occurs, it can be downloaded from the network side. A NAS instruction is sent to instruct to suspend the training data stream, thereby suspending the transmission of the training data stream and/or the training of the AI model and/or the ML model. When the load rate on the network side drops, the suspended service data flow can be resumed through the delivery indicated by the NAS.

In one embodiment, the trigger indication for suspending and resuming the same service data flow may be the same preset indication, or may be different preset indications.

Of course, in another embodiment, the terminal itself can also sense the degree of congestion on the network side or its own resources (the degree of congestion can be measured or reflected by the load rate and/or the amount of remaining resources). Before congestion occurs, the NAS layer on the network side or the NAS layer in the terminal can issue a NAS indication, or the AS layer on the network side can issue an AS indication. Here, the NAS indication or AS indication constituting the preset indication will indicate the UE. The inner AS layer executes the suspension of one or more data streams; when the congestion is relieved or it is predicted that the congestion will not occur in the next time period, the one or more suspended data streams can be resumed through a preset instruction.

In one embodiment, the indication granularity of the preset indication (eg, NAS indication) includes at least one of the following:

flow;

session;

Evolved Radio Access Bear (E-RAB).

The flow here includes but is not limited to quality of service (Quality of Service, QoS) flow (flow).

A session can include one or more data streams.

A data stream may be carried by one or more Data Radio Bearers (DRBs). It is also possible that multiple data streams are carried by one DRB.

An E-RAB may be a resource unit visible to the NAS layer. One E-RAB may correspond to one DRB.

The granularity of the data stream that the preset indication notifies the AS layer to suspend or resume can have any of the above options, so the NAS layer or the AS layer on the network side can suspend and/or resume the data stream at the corresponding granularity according to current needs .

In one embodiment, the responding to the preset indication includes:

Suspend or resume one or more DRBs of the at least part of the data with DRB granularity according to the NAS indication;

According to the AS indication, one or more DRBs of the at least part of the data are suspended or resumed at DRB granularity.

When suspending and/or resuming a data stream, the granularity of the DRB can be performed. For example, the suspended data stream can be: N DRBs; the resumed data stream can be M DRBs.

Both N and M can be any positive integers.

In one embodiment, the S120 may include:

in response to the indication granularity being the flow, suspending the DRB of the flow associated with the NAS indication;

In response to the indication granularity being a flow, restoring the DRB of the flow associated with the NAS indication;

in response to the indication granularity being a session, suspending the DRB of the session associated with the NAS indication;

In response to the indication granularity being a session, restoring the DRB of the session associated with the NAS indication;

In response to the indication granularity being E-RAB, suspend the DRB of the E-RAB associated with the NAS indication;

In response to the indication granularity being E-RAB, the DRB of the E-RAB associated with the NAS indication is restored.

In this embodiment of the present disclosure, the DRBs involved in the suspended flow, session, and/or E-RAB are performed according to the indication granularity indicated by the NAS, and the DRBs involved here may be one or more.

In one embodiment, the method further includes:

In response to the indication granularity being flow granularity, and the mapping relationship between flows and DRBs is N:1, send NAS feedback to the NAS layer, wherein the NAS feedback indicates that the NAS indicates that flows other than the associated flow are suspended or recovery; the N is a positive integer equal to or greater than 2.

Since multiple data streams are mapped to one DRB, if a certain data stream is suspended by the NAS instructed to notify the suspended data stream, because the DRB is used as the granularity to suspend the data stream, it will cause the suspension of other data streams at the same time. In this case, the NAS layer is informed through NAS feedback.

In an embodiment of the present disclosure, the NAS feedback may include: flow identifiers of flows that are not indicated by the NAS to associate flows but are forced to suspend.

Because in general, multiple data streams mapped to the same DRB have some common attributes in transmission, for example, the same transmission priority and/or the same service type and/or the same transmission quality, other than those indicated by the NAS The stream is suspended with little negative impact on the user's communication experience.

In one embodiment, the method further includes:

In response to the indication granularity being a session, and the mapping relationship between the session and the DRB is 1:M, send NAS feedback to the NAS layer, wherein the NAS feedback indicates that the NAS indicates that the associated session is suspended or resumed; The M is a positive integer equal to or greater than 2.

In some embodiments, since the NAS layer is higher than the AS layer, the NAS indication may be performed by the AS layer by default. The AS layer can send NAS feedback to the NAS layer to inform the response result of the current NAS indication, of course, it can also not send the NAS feedback. In this case, the NAS layer can default that the NAS indication is successfully executed.

In other embodiments, the AS layer only sends NAS feedback when necessary, for example, the NAS indicates that the execution failed, and/or the NAS indicates that the flow other than the associated flow has performed a suspend or resume operation before sending the NAS The feedback indicates these contents, which is convenient for the NAS layer to make further subsequent decisions. For example, after the resources of the suspended flow are temporarily released, they are allocated to other service data flows.

In some embodiments, the preset indication includes:

a suspension indication, used to instruct to suspend the at least part of the data;

A resume instruction, used to instruct to resume the at least part of the suspended data.

In the embodiment of the present disclosure, the preset indication can be divided into a suspension indication and a resume indication according to the operation performed by the instructed AS layer. In this way, a suspension indication can independently indicate the suspension of one or more data streams. The resumption instruction can independently instruct the resumption of one or more suspended data streams, where the resumption of the data streams includes but is not limited to: resuming the transmission and/or data calculation of the data streams.

In one embodiment, the preset indication includes:

A suspension indication, indicating the suspension of the at least part of the data and the suspension duration of the at least part of the data.

The preset indication may be a suspend indication alone, in order to facilitate the AS layer to determine when to resume the suspended one or more data streams. The suspension indication carries the suspension duration, so that the AS layer automatically resumes the suspended data flow when the suspension duration of the data stream associated with the suspension indication reaches the suspension duration. For example, the AS layer can configure a suspend timer, and when the timer expires, the AS layer resumes the suspended data flow. In this way, the delivery of preset instructions can be reduced and signaling overhead can be reduced.

In one embodiment, the suspended DRB has at least one of the following characteristics:

Prioritization of non-participating logical channels with suspended DRBs;

Selection of non-participating logical channels with suspended DRBs;

Multiplexing with non-participating logical channels of suspended DRBs;

BSR reporting with the suspended DRB does not participate in the cache.

In response to a suspend indication, suspend one or more data streams, which may include:

Suspend the priority ordering of the logical channel corresponding to the DRB of the suspended data stream, so that if the logical channel of the DRB does not participate in the ordering, it will not be mapped to radio resources for DRB transmission;

Suspend the selection of the logical channel of the DRB of the suspended data stream; since no logical channel is selected, it is obvious that the corresponding data stream will not be mapped from DRB to logical channel, and the logical channel will not be further mapped to physical resources for corresponding data. the transmission of streams;

Suspend the logical channel multiplexing of the DRB of the suspended data stream. Since logical channel multiplexing is not performed, it is obvious that the corresponding data stream will not be mapped from DRB to logical channel, and the logical channel will not be further mapped to physical resources. Carry out the transmission of the corresponding data stream;

If the BSR reporting of the DRB of the suspended data flow is suspended, the network side will not allocate resources for the data flow, for example, no logical channel will be allocated for the data flow; therefore, it is equivalent to suspending the corresponding data flow.

While resuming the data stream, that is, restoring the suspended operation to the executable state, the AS layer will transmit and/or calculate the data stream according to the scheduling instructions and/or configuration parameters of each data stream.

In one embodiment, as shown in Figure 3, the method further includes:

S130: Send NAS feedback to the NAS layer that sends the NAS indication; wherein, the NAS feedback is used to indicate the response result of the NAS indication.

The NAS feeds back a response result indicating at least the NAS, so that it is convenient for the NAS layer to know the current situation of each data stream of the AS layer.

In another embodiment, the method further includes:

Send AS feedback to the AS layer that sends the AS indication; wherein, the AS feedback is used to indicate the response result indicated by the AS.

The AS indication sent here is the AS layer on the network side. The AS layer on the network side includes at least a base station.

The response result includes at least one of the following:

Suspension result; wherein, the suspension result includes: the suspension result of the flow involved in the preset indication and/or the result of sharing the same DRB with the flow involved in the preset indication and the preset indication does not involve the flow pending result;

Restoration results; the restoration results include: restoration results of the streams involved in the preset indication and/or restoration results that share the same DRB with the streams involved in the preset instructions and the preset instructions do not involve streams.

In some embodiments, if the preset instruction involves data flow recovery, the restored data flow may not perform access control, and directly perform operations such as data transmission and/or data calculation according to the resource scheduling before the suspension.

The aforementioned AS feedback and NAS feedback of the UE may be referred to as the execution feedback of the UE.

In some embodiments, the execution feedback may further include: a reason for the failure of the preset indication to respond, and/or a predicted time period for which the preset indication can respond to the preset indication. These contents of the execution feedback can be used by the NAS layer or the AS layer on the network side to determine whether the preset instruction needs to be re-issued, or to determine whether to remove the cause of the preset instruction response failure through debugging; or to determine whether to delay the preset instruction , for example, delaying the effective time indicated by the NAS to the predicted time period.

In some embodiments, the method further includes:

In response to restoring at least a portion of the data stream based on the preset indication, performing access control according to the access parameter;

According to the result of the access control, the response result indicating recovery success or recovery failure is obtained.

If the data flow is restored, access control can be performed in consideration of resource conflicts on the network side and other issues. Of course, the operation of access control here is an optional operation.

In some embodiments, as shown in FIG. 4 , the method further includes:

S100: Send auxiliary information, where the auxiliary information is used to generate the preset indication.

Here, the AS layer of the UE sends the auxiliary information, and the AS layer of the UE may directly send the auxiliary information to the NAS layer, or the AS layer on the terminal side may send the auxiliary information to the AS layer on the network side. If the auxiliary information needs to be forwarded to the NAS layer on the network side, the AS layer on the network side needs to forward or transparently transmit the auxiliary information to the NAS layer on the network side. The NAS layer on the network side here includes, but is not limited to, the core network.

Of course, the preset indication may also be generated independently without referring to the auxiliary information; or the AS layer may not need to report the auxiliary information, and the NAS layer may generate it according to the monitoring of the AS layer. Of course, the NAS layer can also determine the NAS indication by itself according to the resource usage and/or load rate. Alternatively, the AS layer on the network side can also determine the aforementioned AS indication by itself and/or the resource usage status and/or load rate of itself and/or the NAS layer on the network side.

After the access network (such as the base station) receives the NAS message sent by the core network, it is divided into indication granularities according to the flow, session and/or the mapping relationship between E-RAB and DRB. The NAS indication of the DRB is issued to the terminal.

The following is a specific example in conjunction with any of the above-mentioned embodiments:

Mobile applications based on Artificial Intelligence (AI) AI/Machine Learning (ML) are becoming more and more computationally intensive, with high memory consumption and high power consumption. At the same time, end devices often have strict energy consumption, computing and memory cost constraints. Therefore, AI/ML needs to be separated, i.e. split, on the device and the network. That is, offloading the compute-intensive, energy-intensive parts to the network endpoints, leaving the privacy-sensitive and latency-sensitive parts on the end devices. The key to splitting AI/ML operations is to choose the best splitting mode and splitting point to keep the required resources below the upper limit of the resources available on mobile devices, and to optimize compute, storage/memory, power consumption, device and network side communication resources. Usually, when making splitting decisions, the split scheduler will take into account the computing power of the terminal and the network to make reasonable decisions to meet the requirements of AI/ML services running locally or remotely. The decision of the separation scheduler may be determined by the establishment of the service, but after the establishment of the service, the computing resources of the terminal or the network side may change dynamically, such as a remote training service, which involves the terminal uploading data. However, due to the sudden computing power congestion of the network, the business cannot be carried out and needs to be temporarily terminated, that is, suspended. Therefore, this embodiment provides an enhanced link control scheme to implement suspension and resumption of partial data streams.

The NAS instructs the AS layer to suspend and resume some data streams;

As an embodiment, the granularity of part of the data flow is flow (per Qos flow) or session (per PDU session) or E-RAB (per E-RAB).

As an embodiment, the NAS layer may be the NAS layer of the core network or the NAS layer of the UE side. That is, the NAS indication can be a network side command and a terminal local side command.

In one embodiment, when the NAS instructs the AS layer to suspend a part of the data flow with a granularity of session (per PDU session), the AS layer needs to suspend the DRBs corresponding to all flows (Qos flow) under the per PDU session operate.

For example, when the NAS layer instructs the AS layer to suspend some data flows with a granularity of per Qos flow/per E-RAB, the AS needs to suspend the corresponding DRB under the per Qos flow or per E-RAB;

As an embodiment, if the relationship between the Qos flow or per E-RAB and the corresponding DRB is a 1:1 mapping, the DRB is directly suspended.

As an embodiment, if the relationship between the Qos flow and the corresponding DRB is N:1 mapping, the DRB is directly suspended; at this time, other Qos flows are affected, and the AS layer needs to notify the NAS layer of other Qos at this time flow is also forced to suspend.

In view of this situation, if the delivery of the suspend instruction is the network side, the base station informs the core network that other QoS flows are also forced to suspend.

For the suspension indication on the network side, the base station notifies the terminal of the suspension of the data flow through the RRC link release message on the UU interface;

For the suspension indication on the network side, on the UU interface, the base station notifies the terminal of the data flow recovery through the RRC link Resume message;

The base station is responsible for establishing the mapping relationship between per Qos flow/per PDU session/per E-RAB to DRB, so the granularity of air interface message delivery is DRB.

In one embodiment, the NAS instructs the AS layer to display a command recovery mode or adopt an implicit recovery mode for the suspension of a part of the data stream;

As an embodiment, the NAS instructs the AS layer to resume the part of the data flow that was originally suspended;

As an embodiment, the NAS instructs the AS layer to perform timing recovery on part of the data stream that has been suspended; that is, the NAS will specify a suspension duration when issuing the suspension instruction;

In one embodiment, the AS layer suspends and resumes the data flow as follows:

For the suspension of a DRB:

Suspend (suspend) DRB(s), instructing the PDCP layer to suspend its underlying DRB (indicate PDCP suspend to lower layers of the DRB);

The behavior after the AS layer DRB is suspended may include at least one of the following:

MAC layer behavior:

The suspended DRB does not participate in the Logical Channel Prioritization (LCP) procedure (for example, the token bucket is not updated);

The suspended DRB does not participate in the selection of logical channels (Selection of logical channels);

The suspended DRB does not participate in the logical channel multiplexing process (Multiplexing and assembly);

The suspended DRB does not participate in the decision of the BSR reporting process;

RLC layer lines include but are not limited to at least one of the following:

The suspended DRB does not perform periodic polling, even if periodic polling (poll) is configured; for the recovery of a DRB (NAS layer command or automatic recovery):

Optionally, admission control may also be performed before performing DRB recovery; if the admission control process fails, the recovery failure processing flow is entered.

Suspended DRB recovery can be as follows;

Send a recovery response message to the network or the local NAS layer to indicate recovery success or recovery failure, and the information of the DRBs that are recovered successfully or failed recovery may be recorded in the recovery response message in the form of a list. The recovery response message is one of the response results indicated by the aforementioned NAS.

For a resume (resume) request issued by the network, a resume (resume) completion message is returned, which carries a list of DRBs indicating success or failure;

For a resume request issued locally, it is an interaction process between the AS layer and the NAS layer, and the AS returns a list of data streams that succeed or fail; the data stream list can indicate the data streams that are restored successfully or failed.

The UE reports the auxiliary information to assist the network in suspending or resuming a certain data stream.

As an embodiment, the UE can report the auxiliary information to the network directly by reporting the auxiliary information to the base station in the form of an RRC message; in this case, the reporting granularity is a single DRB (Per DRB);

As an embodiment, the UE reports the auxiliary information to the auxiliary network and can transparently report it to the core network in the form of NAS message reporting; at this time, the reporting granularity is: a single flow (per QoS flow) or a single PUD session (per PDU session) or a single (per PDU session) per E-RAB.)

Auxiliary information includes:

Report a pending request for a pending data stream;

Report the reason for suspend;

How long the report is suspended (suspend);

Reports a resume request for a suspended data stream.
