It should be noted that, the method provided by the embodiment of the present disclosure is not limited to being applicable to uplink streaming media, but may also be applicable to downlink streaming media. In the following embodiments, the uplink streaming media is exemplified.
Fig. 4 schematically shows an FLUS framework diagram in the relevant standard.
The upstream service architecture shown in fig. 4 includes an FLUS source (FLUS source) located at the UE (hereinafter referred to as target UE) side, and an FLUS sink (FLUS receiver) located at another UE or network (network). The FLUS source obtains media content from one or more Capture devices (Capture devices), which may be part of the UE or may be devices connected to the UE. The FLUS sink may be located in another UE or in the network.
The upstream network assistance function, uplink Network Assistance (UNA), is defined in the FLUS architecture. The upstream network assistance function, which allows the FLUS source to improve the QoE (Quality ofExperience ) of upstream streaming media sessions, is provided by Network Assistance Server (NAssS, network assistance server). The NAssS provides network assistance information through a different transmission path than the upstream media. The communication of the UNA does not depend on the communication paths of the F-U (Media Source and Sink ) and F-C (Control Source and Sink, control source and sink), and therefore the communication of the UNA occurs on a completely different path than the FLUS streaming media. FLUS sink also does not need to be aware of UNA functionality. The UNA requests network assistance information based on the FLUS source to provide a response message to the FLUS source. The UNA function may provide any one or both of the following information to the flis source:
NAssS indicates the most appropriate upstream streaming media transmission rate for FLUS source in the latter time period.
NAssS indicates flis source temporary delivery boost function (transmission boost function) to address the risk that the content may exceed the output buffer when upstream.
When the uplink network assistance session is activated, a client (in the embodiment of the present disclosure, a functional component in the target UE is a client dedicated to streaming media processing) may issue an uplink network assistance information request before sending the next piece of uplink streaming media content to the FLUS sink. The uplink network assistance request comprises a single logical signaling interaction. This interaction activates either the first function described above or both functions. The second function is only used when the FLUS source grants access to delivery boost function. If the client does not need a release boost, the NassS will delete the second function in the message responding to the FLUS source.
In the definition of the 3GPP standard protocol TS26.501, NAssS are implemented by AFs in the network, providing an uplink transmission rate or delivery boost function to the flis source.
However, in the relevant standard, the interaction flow between the FLUS source and the AF is not defined, i.e. how the AF sends the uplink network assistance information to the FLUS source.
The NWDAF functions are defined in the 3GPP standard protocol TS23.288, and the NWDAF may analyze the existing functions to obtain service experience data/service data information of a past period of time, or may analyze the service experience data/service data information of a future period of time.
In the embodiment of the present disclosure, the service experience data/service data information that may be obtained by the NWDAF includes at least one of the following: a predicted value of the data transmission rate of a certain QoS flow (called a target traffic flow), a predicted value of the packet delay of the uplink or downlink of a certain QoS flow, and the like.
In the embodiment of the disclosure, the predicted value of the data transmission rate of a certain QoS flow predicted by NWDAF refers to a predicted value of the data transmission rate of the QoS flow in a certain time period in the future, and may be used for assisting the flis source to set the uplink streaming media transmission rate; the predicted value of the packet delay of a certain QoS flow predicted by NWDAF refers to a predicted value of the packet delay of the QoS flow in a certain time period in the future, and may be used to adjust related parameters of the streaming media, for example, to assist the FLUS source in setting a suitable buffer value (for indicating the size of an output buffer of the streaming media to be sent), or to adjust a coding algorithm to match the state of the network, etc. Accordingly, embodiments of the present disclosure propose to send NWDAF predicted traffic data information (including uplink data transmission rate predictors and/or packet delay predictors) to the flis source.
Specifically, the flis source may directly set the received data transmission rate prediction value of the QoS flow to the streaming media transmission rate of the streaming media to be sent in the later period, or may use the received data transmission rate prediction value of the QoS flow to assist in setting the streaming media transmission rate of the streaming media to be sent in the later period, which is not limited in the disclosure.
It may be understood that, if the method provided in the embodiment of the present disclosure is applicable to downstream streaming media, the target UE directly sets the received data transmission rate prediction value of the QoS flow to the streaming media transmission rate of the streaming media to be received in the later period, or may use the received data transmission rate prediction value of the QoS flow to assist in setting the streaming media transmission rate of the streaming media to be received in the later period, which is not limited in the present disclosure.
In the embodiment of the disclosure, when the delay predicted value of the received data packet of the QoS flow is larger, it is indicated that the network is in a poor state at this time, and relevant parameters of the streaming media can be adjusted, for example, a buffer value with larger corresponding settings is used for buffering the streaming media to be sent, so as to prevent data packet loss caused by poor network state; when the delay predicted value of the received data packet of the QoS flow is smaller, it indicates that the network state is better at this time, and the relevant parameters of the streaming media can be adjusted, for example, a smaller buffer value is correspondingly set for buffering the streaming media to be sent.
It can be understood that if the method provided by the embodiment of the present disclosure is suitable for downstream streaming media, when the delay predicted value of the data packet of the QoS flow received by the target UE is larger, it indicates that the network is in a poor state at this time, and relevant parameters of the streaming media can be adjusted, for example, a buffer value with a larger size is correspondingly set, so as to buffer the streaming media to be received, so as to prevent data packet loss caused by poor network state; when the delay predicted value of the received data packet of the QoS flow is smaller, it indicates that the network state is better at this time, and the relevant parameters of the streaming media can be adjusted, for example, a buffer value which is correspondingly set smaller is used for buffering the streaming media to be received.
In the embodiment of the present disclosure, a target UE may be preconfigured to multiple optional coding algorithms of a streaming media to be transmitted (the type and number of specific coding algorithms may be set according to an actual application scenario, which is not limited in the present disclosure), or different parameter values may be configured for the coding algorithms, when a packet delay predicted value of a received QoS stream is larger, which indicates that a network is in a poor state at this time, relevant settings or parameters of the streaming media may be adjusted, for example, a corresponding coding algorithm with smaller coding complexity and lower coding performance may be selected as a target coding algorithm of the streaming media to be transmitted, so as to match a network state at this time; when the delay predicted value of the received data packet of the QoS stream is smaller, the network state is better at the moment, and the relevant setting or parameters of the stream media can be adjusted, for example, the corresponding coding algorithm with higher coding complexity and higher coding performance is selected as the target coding algorithm of the stream media to be transmitted so as to match the network state at the moment.
It can be understood that, if the method provided by the embodiment of the present disclosure is applicable to downstream streaming media, multiple optional decoding algorithms (the type and number of specific decoding algorithms may be set according to an actual application scenario, etc.) may be provided in advance to the streaming media to be received in the target UE (the disclosure is not limited to this), and when the delay predicted value of the data packet of the received QoS stream is larger, it is indicated that the network is in a poor state at this time, and the relevant settings or parameters of the streaming media may be adjusted, for example, the corresponding decoding algorithm with smaller decoding complexity and lower decoding performance may be selected as the target decoding algorithm of the streaming media to be received, so as to match the network state at this time; when the delay predicted value of the received data packet of the QoS stream is smaller, the network state is better, and the relevant parameters of the streaming media can be adjusted, for example, a decoding algorithm with higher decoding complexity and higher decoding performance is selected correspondingly as a target decoding algorithm of the streaming media to be received so as to match the network state at the moment.
In the embodiments of the present disclosure, a NAS (Non-Access Stratum) message (specifically referred to as a target analysis Non-Access Stratum request cell, corresponding to Analytic NAS container below) is defined, and is used to transmit request and response messages between the flis source (i.e., the target UE) and the target NWDAF. The NAS message is sent to the 5G AN by the target UE, then to the AMF by the 5G AN, and then to the target NWDAF by the AMF. Neither the 5G AN nor the AMF parses the NAS message, but only transparently passes the message.
It should be noted that, in the embodiment of the present disclosure, the target analysis non-access stratum request cell refers to a packed message body, which is a packed aggregate of data, and parameters of what kind of data analysis prediction is required by the UE are packed in a container through the container, and the parameters are not analyzed by AN intermediate network element (for example, 5G AN and AMF), and are directly transmitted to a network element (for example, NWDAF) that analyzes the parameters, so that the name in the final writing standard is not limited to Analytic NAS container, and may be determined according to negotiation. The target analysis non-access stratum response cell refers to a packed message body, which is a packed aggregate of data, and the result of data analysis prediction of the target analysis non-access stratum request cell to be received by the UE is packed in a container through the container, the intermediate network element does not analyze the result and directly transmits the result to the target UE analyzing the result, so that the name of the final written standard is not limited to Analytic NAS container and can be determined according to negotiation.
A specific business flow diagram is shown in fig. 5, which may include the following steps.
And 0, when the target UE is in an idle state, the target UE initiates a service request (service request) flow, and establishes NAS connection with the AMF.
Step 1, the target UE sends a terminal data analysis prediction request message to the AMF, where the terminal data analysis prediction request message carries an analytical ID (target analysis identifier), an NWDAF ID (target network data analysis function identifier, optional parameter), analytic NAS container [ analytical sub-ID (target analysis identifier, optional parameter), target of Analytics Reporting (analysis report destination address) =ue ID (target UE identifier), analytics Filter information (analysis filter information) = (at least one parameter information: application ID (i.e. target Application identifier, e.g. video APP (Application) ID on the target UE), but not all APPs have to have ID), IP filter information (IP filter information, may refer to FLUS sink server address information, i.e. destination address information of the streaming media to be sent, so that it may be known for which target traffic flow), FQDN, PDU session ID (and including QFI)), area information (Area of Interest), i.e. prediction information for which Area requested by the target UE), and analysis aid information (Analytics Reporting Information)).
In embodiments of the present disclosure, analytics Reporting Information may include analysis report information parameters, such as event reporting mode (Event Reporting mode), reporting modes may be set, such as maximum analysis report times (a maximum number of reports), periodicity of analysis reports (periodic reporting along with periodicity), and so forth.
Step 2, the AMF selects an appropriate NWDAF (referred to as a target NWDAF) for the terminal data analysis and prediction request message of the target UE.
If the terminal data analysis and prediction request message carries a target NWDAF ID, the AMF selects a target NWDAF corresponding to the target NWDAF ID; the AMF may also reselect a new NWDAF, which may retrieve the analysis prediction information related to the target UE from the old NWDAF (i.e. the NWDAF indicated by the NWDAF ID contained in step 1). If the request message does not carry the target NWDAF ID, the AMF selects the NWDAF supporting UE analytical as the target NWDAF according to the configuration or the service discovery procedure of the NRF.
In the embodiment of the present disclosure, in the process of selecting the target NWDAF, the following factors may be considered with reference to the existing standard-defined method:
-S-NSSAI。
analytics ID(s) (target analysis ID).
NWDAF Serving Area information (NWDAF service area information).
The AMF invokes the data analysis and prediction service of the target NWDAF, and transmits a data analysis and prediction subscription message to the target NWDAF, where the data analysis and prediction subscription message includes UE ID, analytic NAS container [ analytical ID, analytical sub-ID, target of Analytics Reporting =ue ID, analytics Filter information = (at least one of the following parameter information: application ID, IP filter information, FQDN, PDU session ID (may further include QFI)), area of Interest, analytics Reporting Information ].
In the embodiment of the present disclosure, notification Target Address (+ Notification Correlation ID) (notification destination address (+notification related ID) may also be included in the data analysis prediction subscription message, that is, notifying the target NWDAF of which service and corresponding notification related ID to return to the AMF when the target NWDAF returns the data analysis prediction notification message in response to the data analysis prediction subscription message.
And 3, after receiving the data analysis and prediction subscription message, the target NWDAF determines which NF is used as a target network element according to parameters such as an analytical ID, an analytical sub-ID and the like in Analytic NAS container, and determines that corresponding data information is received from the target network element as target data.
And 4, when the target NWDAF analyzes the target data, an analysis and prediction result of the target service flow of the target UE in a future period of time can be obtained, so as to serve as network auxiliary information. The target NWDAF transmits a data analysis prediction notification message to the AMF, the data analysis prediction notification message including the UE ID, analytic NAS container [ analytical ID, analytical sub-ID, analytics information, timestamp information of the prediction result, validity time of the prediction result, validity place of the prediction result, prediction confidence ].
Analytic NAS container in step 4 corresponds to the target analyzing the non-access stratum response cells.
Correspondingly, the data analysis forecast notification message may also include Notification Target Address (+ Notification Correlation ID).
And 5, if the target UE is in an idle state, the AMF firstly pages the target UE, and NAS (Non-access stratum) connection between the target UE and the AMF is established. When the target UE is in a connected state, the AMF transmits a terminal data analysis prediction response message to the target UE, the terminal data analysis prediction response message Analytic NAS container [ analytical ID, analytical sub-ID, analytics information, timestamp information of the prediction result, effective time of the prediction result, effective location of the prediction result, prediction confidence ].
In addition, when the target UE generates a registration area update and changes the AMF, the new AMF updates the connection with the target NWDAF at the same time when the registration area update procedure is completed, that is, the target NWDAF stores the new AMF ID information.
In the embodiment of the disclosure, the network auxiliary information may include analytics information, timestamp information of the predicted result, effective time of the predicted result, effective location of the predicted result, and prediction confidence. Analytics information may be specifically determined according to an analysis ID and an analysis sub-ID, and may include, for example, a data transmission rate prediction value of a target traffic flow corresponding to the target traffic flow identifier and/or a packet delay prediction value of the target traffic flow.
In the embodiment of the disclosure, the following three optional analytical ID setting modes are provided:
parameter optional setting mode one:
if the analytical id=ue analysis (user terminal analysis) in the above step 1 and the analytical sub-id= Service experience (service experience) are added, the Analytics information in the above step 4 may specifically include at least one of the data transmission rate prediction value and the packet delay prediction value of the target QoS flow.
And a parameter selectable setting mode II:
if the analytical id= Service experience in the step 1 is increased by the analytical sub-id= bitrate recommendation (bit rate recommendation), or/and the analytical sub-id=latency (delay), analytics information in the step 4 contains the content requested in the analytical sub-ID, that is, the predicted value of the data transmission rate of the target QoS flow, or/and the predicted value of the packet delay.
And a parameter selectable setting mode III:
if the analytical id=ue analytical in step 1 is increased by the addition of the analytical sub-id= bitrate recommendation, or/and the analytical sub-id=latency, analytics information in step 4 contains the content requested in the analytical sub-ID, i.e. the predicted data transmission rate of the target QoS flow, or/and the predicted data packet delay.
It will be appreciated that the meaning represented by the particular parameter values of the analytical ID and the analytical sub-ID may be determined in accordance with negotiations and is not limited to the above exemplified cases and named names. For example, it may be set that UE Analytic container only needs to include an Analytics ID, and once the target NWDAF receives UE Analytic container, the target NWDAF may know that the target UE requests to perform data analysis prediction of the target UE, and at this time, the target NWDAF may return the predicted data transmission rate prediction value of the target QoS flow corresponding to the target Analytics ID and/or the data packet delay prediction value to the target UE through the AMF. For another example, if UE Analytic container only includes an analysis ID, the target NWDAF may return the predicted data transmission rate prediction value and the packet delay prediction value of the predicted target QoS flow corresponding to the target analysis ID to the target UE through the AMF; if UE Analyticcontainer includes both an analysis ID and an analysis sub-ID, the predicted data transmission rate predicted value and/or the predicted data packet delay predicted value of the target QoS flow are returned to the target UE according to the values of the analysis ID and the analysis sub-ID.
The embodiment of the disclosure provides a network auxiliary information providing method capable of sending NWDAF predicted service information data (i.e., network auxiliary information) to an flis source. I.e. a method is provided for providing predicted traffic information data to the flis source by the NWDAF and extends the scope of the side information. That is, compared with the technology in the related standard, the AF, which is the disclosed standardized method of NAssS, may return a data transmission rate prediction value (bitrate recommendation ) of a target traffic flow corresponding to the target traffic flow identifier, and may also return a packet delay prediction value (latency) of the target traffic flow. After receiving the returned network auxiliary information, the target UE can assist in the optimization processing such as the setting of the streaming media transmission rate, the setting of the size of an output/input buffer zone, the matching of a coding and decoding algorithm and the like.
