XR services involve a multi-modal data stream, which is data input from the same device or different devices (including sensors) describing the same service or the same application, which may be output to one or more destination device terminals. The data streams in multimodal data often have some or even strong correlation, such as synchronization of audio and video streams, synchronization of haptic and visual, etc. The data flow of the media service, the data flow and the demand of the service data flow for network transmission have common characteristics, and the effective identification and utilization of the characteristics are more beneficial to the transmission and control of the network and the service guarantee and the user experience.

In step S2101, the AF function node 101 transmits a first message to the first core network function node 102-1.

In some embodiments, the first core network function node 102-1 receives the first message. The first core network function node 102-1 is a PCF.

In some embodiments, the first message is for requesting creation or update of an AF session.

In one example, the first message may Create (Nnef _ AFsessionWithQoS _create) a request message for the AF session.

In one example, the first message may be an AF session Update (Nnef _ AFsessionWithQoS _update) request message.

In some embodiments, the name of the first message is not limited, and may be replaced by an AF session creation request message, an AF session update request message, or the like.

In some embodiments, the first message is further used to provide a Differential Service Code Point (DSCP) map of PDU set dependencies to the first core network function node 102-1.

In some embodiments, the first message may include, but is not limited to, at least one of:

First indication information; the first indication information is used for indicating the first core network function node to consider the DSCP mapping of the PDU set correlation when determining Policy AND CHARGING Control (PCC) rules;

In one example, DSCP mapping of PDU set dependencies may be performed by the AF function node 101 to obtain the DSCP label value, which is provided directly to the first core network function node 102-1 via the first message.

Illustratively, the AF function node 101 may perform DSCP mapping of PDU set dependencies based on a predefined manner or protocol-agreed mapping relation.

For example, assuming that the PDU set correlation is not considered, the DSCP label value may range from 0, N, where N may be 63. The DSCP label value may be refined when PDU set correlation is considered, for example, DSCP label value #1 is mapped when PDU set correlation is not considered, and DSCP label value #11, DSCP label value #12, DSCP label value #13 … … are mapped based on different PDU set correlation.

Or the range of DSCP tag values may be extended, for example to 0, M, where M is greater than N.

The above is merely exemplary, and all schemes of the DSCP label value obtained by the AF function node 101 performing the DSCP mapping of the PDU set correlation shall fall within the protection scope of the present disclosure.

In one example, the AF function node 101 may not perform DSCP mapping of PDU set correlation, but may carry first indication information in a first message, where the first indication information is used to instruct the first core network function node 102-1 to consider the DSCP mapping of PDU set correlation when determining PCC rules.

In one example, the above-described association information may include, but is not limited to, at least one of:

Wherein the QoS parameters include, but are not limited to, at least one of: end-to-end delay; a 5G QoS identifier, an address resolution protocol (Address Resolution Protocol, ARP), a stream bit rate, priority, etc.

In one example, one or more of the DSCP tag value, the first indication information, the association information may be included in the first message.

In some embodiments, PDU set correlation is used to identify correlations or dependencies between PDU sets.

In one example, the PDU set correlation is used to identify at least one of:

correlation (or dependency) of PDU sets among different QoS flows of the same service;

correlation (or dependency) of PDU sets within the media transport stream traffic stream of the same service;

Correlation (PDU set) or dependency (dependency) between media transport streams of the same service;

Correlation (or dependency) of a set of PDUs in the same connection stream in connection channels connection of the same service;

Correlation (or dependency) of PDU sets in different connection streams within a connection channel connection of the same service.

The media transport stream may include one or more service data streams, and the service data streams may be XR service streams such as video streams, audio streams, and the like.

The connection channel connection may include one or more stream streams. In the embodiment of the disclosure, the PDU set correlation is described, which can identify the correlation or the dependency between PDU sets under different transmission granularities (for example, in the same QoS flow, between different QoS flows of the same service, in a media transport flow of the same service, between media transport flows of the same service, in the same connection flow in connection channel connection of the same service, in different connection flows in connection channel connection of the same service), so that the availability and reliability of the PDU set characteristic parameter of the PDU set correlation are improved, the end-to-end QoS requirement is effectively ensured, and the end-to-end QoS resource can be better cooperated.

The above is merely exemplary, and the correlation (dependency) or dependency (dependency) between PDU sets may be identified by PDU set correlation, which is not limited by the present disclosure.

In some embodiments, the information of PDU set dependencies has at least one of the following properties:

The PDU set with correlation (or dependency) belongs to one PDU group;

Each PDU set comprises an anchor PDU set (key PDU set); wherein the PDU set correlation is a correlation or dependency of other PDU sets in the PDU set with respect to the anchor PDU set.

In one example, the information of PDU set correlation is used to indicate at least one of:

the first PDU set does not meet PSDB, and the transmission of the first PDU set is abandoned;

For example, the second transmitted set of PDUs within the PDU set may not be successfully transmitted, e.g., to the receiver, and the third and fourth sets of PDUs … … within the PDU set may be discarded.

For another example, a certain set of PDUs within a PDU set, i.e., the first PDU does not satisfy the PSDB, may forego transmitting the first set of PDUs.

For another example, the anchor PDU set in the PDU set may be prioritized with a priority of 1, and the priorities of the other PDU sets in the PDU set may be prioritized assuming that the priorities are all 2.

For another example, an anchor PDU set within a PDU set changes priority, assuming the priority drops to 2, and it may be desirable to change the priorities of other PDU sets within the PDU set, assuming the priorities of the other PDU sets all drop to 3.

For another example, the PDU set importance of the anchor PDU set in the PDU set is 1, the PDU set importance of the other PDU sets is 4, and when the PDU set importance of the anchor PDU set is reduced to 2, the PDU set importance of the other PDU sets is also reduced, assuming to be reduced to 5.

In one example, at least one of the above may be indicated by bits (bits).

For example, the PDU set correlation information may represent the above situation with at least 5 bits, and when a bit value corresponding to each situation is a first value, for example, "1", it is used to indicate that there is a corresponding situation.

For example, the bit value corresponding to the information of the PDU set correlation is "10011", and then the information of the PDU set correlation may be used to indicate that the anchor PDU set in the PDU set is not successfully transmitted, the other PDU sets in the PDU set are abandoned to be transmitted, the priority is set or changed by the anchor PDU set in the PDU set, the priority is also set or changed by the other PDUs in the PDU set, and the PDU set importance of the anchor PDU set in the PDU set is changed, and the PDU set importance of the other PDU sets in the PDU set is also changed in an associated manner.

Illustratively, the information of PDU set correlation may represent the above-described situation or a combination of situations with a plurality of bits. For example, when the bit value corresponding to the information of the PDU set correlation is "001", the method is used for indicating that the anchor PDU set in the PDU set is not successfully transmitted and discarding the transmission of other PDU sets in the PDU set, when the bit value corresponding to the information of the PDU set correlation is "101", the method is used for indicating that the anchor PDU set in the PDU set is not successfully transmitted and discarding the transmission of other PDU sets in the PDU set, and the anchor PDU set in the PDU set sets or changes priority, and the other PDUs in the PDU set also set or change priority.

The foregoing is merely exemplary, and a scheme in which information about PDU set correlation is indicated by a bit manner shall fall within the protection scope of the present disclosure.

The information of the PDU set correlation may also indicate the corresponding situation by other means.

Illustratively, the information of the PDU set correlation may indicate the corresponding situation by setting "true" or "false".

The corresponding situation may be indicated by way of example by carrying a corresponding information element (Information Element, IE). For example, the anchor PDU set in the PDU set is not successfully transmitted, and the transmission of other PDU sets in the PDU set is abandoned corresponding to the first IE (or other names of IEs), the preamble PDU set in the PDU set is not successfully transmitted, and the transmission of the subsequent PDU set not transmitted in the PDU set is abandoned corresponding to the second IE … …. If the information of the PDU set correlation includes a first IE, the information of the PDU set correlation is used for indicating that the anchor PDU set in the PDU set is not successfully transmitted and discarding the transmission of other PDU sets in the PDU set.

The foregoing is merely exemplary and is not intended to limit the present disclosure.

The foregoing is further illustrated below.

In implementations of the present disclosure, a DSCP map of PDU set dependencies is added (DSCP MAPPING WITH PDU Set Correlation).

The DSCP mapping of PDU set dependencies indicates that the PDU set dependency information can be used for DSCP marking on external header of PDU set packets on the N3/N9 interface in the transport network (i.e., to implement differentiated handling of transport packets carrying PDU set dependencies).

PDU set correlation may be used to identify how this PDU set is correlated (dependency) or dependent with other PDU sets.

In one example, the PDU set correlation is used to identify at least one of:

The information of the PDU set correlation has at least one of the following properties:

a) The related set of PDUs is part of a set of PDUs.

B) Each group has a set of PDUs representing an "anchor" set of PDUs.

Furthermore, the information of PDU set dependencies will indicate a slave PDU set (DEPENDENT PDU SET,) which may indicate the following dependencies:

The "anchor" PDU set fails to pass to the receiver (e.g., due to congestion or retransmission timeout, etc.), giving up the transmission.

-The previous set of PDUs failed to be delivered to the receiver, giving up the transmission.

The PSDB cannot be satisfied and the transmission is aborted.

Set priority or cancel priority (set priority or cancel priority for the anchor PDU set).

Change PDU set importance (anchor PDU set changed PDU set importance).

The AF function node may provide a DSCP mapping with PDU set correlation to a 5G core network (5 GCore,5 GC), where 5GC includes, but is not limited to PCF, SMF, UPF and the like. The DSCP mapping of PDU set dependencies may be used for PCC determination (e.g., for determining a transport layer packet marker value (e.g., DSCP value of outer IP header).

AF function node:

The AF function node may use Nnef _ AFsessionWithQoS _create request message or Nnef-AFsessionWithQoS _update request message to provide DSCP mapping with PDU set correlation.

First core network functional node (PCF device):

the PCF device determines PCC rules considering the DSCP map with PDU set correlation and sends the DSCP map with PDU set correlation to a second core network function node (SMF device). Further, DSCP mappings with PDU set dependencies may be sent to the SMF in PCC rules.

Second core network function node (SMF device): :

The SMF device may provide a DSCP map with PDU set dependencies to at least one of a third core network function node (UPF device) and a terminal, wherein the UPF map is downstream and the terminal is upstream to indicate DSCP label values taking into account PDU set dependencies and/or PDU set information and related QoS information.

Third core network function node (UPF device): :

The UPF device will add DSCP tag values on the outer header of the downlink packets of the PDU sets on the N3/N9 interface in the transport network (i.e. implement differentiated handling of transport packets carrying PDU set dependencies) taking into account PDU set dependencies and/or PDU set information and related QoS information.

Access network equipment (RAN):

The NG-RAN implements QoS proflie corresponding to the relevant DSCP, i.e. uses DSCP indication or DSCP information in view of PDU set correlation and/or PDU set information and relevant QoS information for transmission resource allocation.

If the SMF device provides DSCP indication or DSCP information to the NG-RAN in view of PDU set correlation and/or PDU set information and related QoS information, the NG-RAN will replace the previously stored DSCP indication or DSCP information with it.

Fig. 4A is an interactive schematic diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in fig. 4A, an embodiment of the disclosure relates to an information transmission method, in which a first core network function node is a PCF, a second core network function node is an SMF, a third core network function node is a UPF, and a fourth core network function node is a NEF, where the method includes:

in step S4101, the AF sends an AF session resource creation or update request.

An AF session is created or updated, for example, by Nnef _ AFsessionWithQoS _create/update request.

The AF may use Nnef _ AFsessionWithQoS _create request message or Nnef-AFsessionWithQoS _update request message to provide DSCP mapping with PDU set correlation.

AF provides DSCP mapping with PDU set correlation to 5GC (PCF/SMF/UPF) for PCC determination. For example, a marker value, e.g., DSCP tag value, for an outer IP header, is used to determine the transport level packet.

The DSCP mapping of PDU set dependencies indicates that the information of PDU set dependencies can be used for DSCP marking on the outer header of the packet of the PDU set on the N3/N9 interface in the transport network (i.e., to implement differentiated handling of transport packets carrying the PDU set dependencies).

PDU set correlation is used to identify how this PDU set is correlated (or dependent) with other PDU sets.

In one example, the PDU set correlation is used to identify at least one of:

The connection channel connection may include one or more stream streams.

The PDU set correlation information has at least one of the following properties:

a) The related set of PDUs is part of a set of PDUs.

B) Each group has a set of PDUs representing an "anchor" set of PDUs.

Furthermore, the information of PDU set dependencies will indicate a set of slave PDUs, which may indicate the following dependencies:

The PSDB cannot be satisfied and the transmission is aborted.

Change PDU set importance (anchor PDU set changed PDU set importance).

Optionally, XRM service information is carried, and the XRM service data stream or data stream group (for example, multi-mode service identifier multi-modal SERVICE ID) is identified, terminal address information and/or terminal identification information, AF identifier application identification information, flow description information (S)), DNN, S-NSSAI, qoS parameter (parameters) and the like are identified. Here multi-modal SERVICE ID can be used to identify all flows in XRM service group.

In step S4102, the NEF grants the AF request.

If the AF is not trusted, an AF request is sent to the PCF through the NEF.

Optionally, the NEF performs a correlation mapping including a mapping identifying XRM Service (AF-Service-Identifier) to DNN and S-NSSAI, a mapping externally applied to CN application identification; and mapping the external UE identity to the in-CN UE identity (e.g., SUPI) based on the UDM subscription information, and performing mapping of the external to internal XRM service group identity according to the UDM subscription information.

In step S4103, the NEF determines whether to invoke TSCTSF or to contact the PCF directly based on the parameters provided by the AF.

The PCF receives the AF-provided attributes from the NEF or TSCTSF. The NEF triggers Npcf _ PolicyAuthorization _Create request to send AF request to PCF, carrying indication and QoS requirement information for PCF policy decision.

In step S4104, the PCF makes a policy decision. The PCF may determine that updated or new policy information needs to be sent to the SMF.

The PCF determines PCC rules considering DSCP mappings with PDU set dependencies and sends the DSCP mappings with PDU set dependencies to the SMF. Further, DSCP mappings with PDU set dependencies may be sent to the SMF in PCC rules.

In step S4105, the PCF responds to the NEF response Npcf _ Policy Authorization _create response.

In step S4106, the NEF sends Nnef _ AFsessionWithQoS _create response message to the AF. Carrying Result information to inform whether the AF request is authorized.

In step S4107, the PCF initiates an SM policy association modification request to the SMF.

The message may be Npcf _ SMPolicyControl _ UpdateNotify request message.

Upon receiving the PCC rules, the SMF determines QoS rules and QoS set parameters to configure/activate the rules to the UPF (e.g., via an N4 session).

The SMF will provide a DSCP mapping of PDU set dependencies to at least one of the UPF and the terminal (UPF mapped DL, UE mapped UL) to indicate a DSCP label value taking into account PDU set dependencies and/or PDU set information and related QoS information.

The SMF will provide DSCP mapping with PDU set correlation to the UPF and/or NG-RAN and/or terminal to indicate QoS enforcement.

The SMF derives QoS parameters of the QoS flow based on PCC rule information of PCC rules bound to the QoS flow.

In step S4108, the SMF replies an SM policy association modification response to the PCF.

The message may be Npcf _ SMPolicyControl _ UpdateNotify response message, among others.

In step S4109, the SMF triggers a PDU session modification procedure to provide QoS profiles to the UPF and/or NG-RAN.

Considering PDU set correlation and/or PDU set information and related QoS information, the PSA UPF will force DSCP marking on the outer header of the downlink packets of the PDU set on the N3/N9 interface in the transport network (i.e. implement differentiated handling of transport packets carrying PDU set correlation).

The NG-RAN enforces a QoS profile corresponding to the relevant DSCP, i.e. uses DSCP indication or DSCP information taking into account PDU set correlation and/or PDU set information and relevant QoS information for transmission resource allocation.

If the SMF provides DSCP indication or DSCP information to the NG-RAN in view of PDU set correlation and/or PDU set information and related QoS information, the NG-RAN will replace the previously stored DSCP indication or DSCP information with it.

Referring to fig. 4B, steps S4201 through S4208 are similar to steps S4101 through S4108 described above, and are not described again here, step S4109 may include steps of,

In step S4209, the SMF sends an N4 session modification request message to the UPF.

The message may be an N4 Session Modification Request message. The SMF provides the upc with DSCP mapping of PDU set dependencies via the message.

Step S4210, the UPF sends an N4 session modification response message to the SMF.

The message may be an N4 Session Modification Response message.

Step S4211-1, the SMF sends an N1N2 message switch message to the AMF.

Wherein the SMF provides DSCP mapping of PDU set dependencies to the AMF through Namf _communication_n1n MESSAGE TRANFER message.

Step S4211-2, AMF responds to the N1N2 message switch message.

The AMF sends an N2 message to the RAN device and provides DSCP mapping of PDU set dependencies, step S4212.

In step S4213, the RAN apparatus may perform resource scheduling and configuration for the terminal.

Step S4213 is an optional step.

In step S4214, the RAN device sends an N2 message to the AMF device, in response to the N2 message sent before the AMF.

In step S4215, the AMF transmits a session management context update request message to the SMF.

The message may be Nsmf _ PDUSession _ UpdateSMContext Request message.

In step S4216, the SMF transmits a session management context update response message to the AMF.

The message may be Nsmf _ PDUSession _ UpdateSMContext Response message.

In step S4217, the SMF sends an N4 session modification request message to the UPF.

The message may be an N4 Session Modification Request message.

Step S4218, the UPF sends an N4 session modification response message to the SMF.

The message may be an N4 Session Modification Response message.
