[0036] In multimedia applications such as the Metaverse and XR, multiple data streams often exist in the same application (also called the same traffic) scenario. For example, different data streams, such as audio, video, haptic, or other sensors, exist simultaneously, and synchronization between the multiple data streams is required to ensure the user experience. In real applications, different data streams may be initiated by different applications, and the data streams may be carried on the network slices subscribed to by the corresponding applications and processed by different UPFs, making synchronization operations at the packet granularity impossible. As a result, synchronization between the multiple data streams cannot be guaranteed.

[0037] Based on this, in each embodiment of the present application, a first network device receives first information representing a relationship between at least two data streams and determines a first network policy based on the first information; a second network device receives the first network policy and distributes the first network policy to a transmitting terminal of the at least two data streams, the at least two data streams are transmitted based on the first network policy; and a third network device transmits the at least two data streams to a first UPF with packet granularity coordination capabilities. Based on the above solution, when data streams belonging to different applications both support the same task, the first network policy is formulated so that these multiple data streams are carried in the same network slice or the same PDU session, allowing synchronization operations at packet granularity within the same UPF. This cooperatively ensures synchronization between multiple data streams initiated by different applications.

[0038] In the following, the present application will be explained in more detail with reference to the figures and examples.

[0039] First, in each embodiment of the present application, the first network device may be a PCF, the second network device may be an NEF or a RAN or a UDR or a UDM or an AMF or an SMF or an AF, and the third network device may be a PCF or an AMF or a RAN or an SMF or an AF.

[0040] An embodiment of the present application provides an information processing method applied to a first network device, and as shown in FIG. 1, the method includes the following steps:

[0041] In step 101, first information is received.

[0042] In step 102, a first network policy is determined based on the first information.

[0043] Here, the first information is used to represent a relationship between at least two data streams.

[0044] wherein the first information is used to represent a relationship between at least two data streams, and representing the relationship between the at least two data streams includes: indicating that at least two data streams belong to one data stream group; representing that at least two data streams constitute one data stream group; Representing that at least two data streams belong to the same business; Representing at least two data streams carrying the same transaction; The at least two data streams represent that they relate to the same business.

[0045] Here, the business can be understood as a service, a multi-modality service, or the like.

[0046] Belonging to one data stream group can be understood as these data streams having the same data stream group identification information, and this identification information is used to identify these streams as belonging to the same data stream group.

[0047] Forming a data stream group can be understood to mean that the data streams have indicator information, and the data streams can be processed as a data stream group based on, with reference to, taking into account, according to, or combining the indicator information. The indicator information here may be the same, and the data streams are processed as a data stream group based on the same indicator information. The indicator information here may be different, and even if the indicator information is different, the data streams can be processed as a data stream group based on the relationship between the indicator information, with reference to, taking into account, according to, or combining the relationship between the indicator information, or based on a pre-configured rule. The indicator information here may have other names, may be specialized, explicit indicator information for indicating the relationship between the data streams, or may use existing parameters, fields, or information, and the first network device processes the data streams as a data stream group based on the relationship between the indicator information and / or a pre-configured rule.

[0048] Belonging to the same business can be understood as multiple data streams having a common identifier, which indicates that these data streams belong to the same business.

[0049] Carrying the same business is understood to mean that data or information or content of the business is carried in these data streams.

[0050] Associated with the same business may be understood to mean that these data streams serve the same business, or that these data streams support the same business, or that these data streams are associated with the same business in some other way.

[0051] In a practical application, the at least two data streams cooperate to support a first task, and the different data streams belong to different applications. Alternatively, when different applications are executed on different terminals, the different data streams can be understood to belong to different terminals. For example, in an XR task, the data stream output to the VR glasses and the data stream output to the force feedback device need to be synchronized. In this case, the two data streams belong to the VR application and the force feedback application, respectively, or the two data streams belong to two terminals, the VR glasses and the force feedback device, respectively.

[0052] In a real application, when an application subscribes, it notifies the network side which data streams of that application need to be synchronized with other applications. For example, application 1 notifies the network side which data streams of application 1 need to be synchronized with the data streams of application 2 and application 3.

[0053] In a practical application, after a terminal corresponding to at least two different applications simultaneously supporting a first service accesses the AF, the AF recognizes that these applications are simultaneously processing the first service, and then the AF reports first information to request that a first network policy be determined for these data streams cooperatively supporting the first service.

[0054] In one embodiment, the first information is: The QoS monitoring requirement includes at least one of application information, IP5 tuple information of the application, application group information, QoS requirements of the application, a common ID, data stream group information, network slice information, DNN, QoS monitoring requirements, time information related to the first network policy, and a time interval for executing the first network policy, where the time interval can be expressed as a time window or a time period, and the QoS monitoring requirements include at least one of a reporting frequency, a reporting period, and a reporting path.

[0055] In a practical application, the first information may be originated by the AF or the NEF and transmitted to the first network device.

[0056] Specifically, the transmission of the first information can be realized by adding new information Application coordination to the Route Selection Descriptor, which can indicate that at least two data streams belong to one data stream group or constitute one group of data streams.

[0057] When the first information is transmitted by an AF, the business requirements of the at least two data streams are the same.

[0058] Furthermore, when the first network policy is URSP, the business requirements of the at least two data streams are the same. The business requirements established for the URSP by the at least two data streams are the same.

[0059] Here, if the at least two data streams have the same business requirements established for the URSP and these data streams are transmitted by one terminal, it can be ensured that these data streams are carried in one PDU session, or if these data streams are transmitted by multiple terminals, it can be ensured that these data streams are carried in PDU sessions corresponding to the same network slice or the same DNN combination.

[0060] In this embodiment, determining the first network policy may be the first network device itself determining, certifying, or formulating the first network policy, or another network device formulating the first network policy and the first network device obtaining the first network policy from the other network device. Here, determining the first network policy based on the first information can be understood as determining the first network policy taking the first information into consideration, or determining the first network policy based on the first information, or determining the first network policy by referring to the first information, or determining the first network policy in combination with the first information.

[0061] In one embodiment, the first network policy comprises: that at least two data streams are carried by the same PDU session; The network slice selection policies or URSPs of at least two data streams are the same; When the URSP corresponding to at least one data stream in a data stream group is changed, the URSPs corresponding to other data streams in the data stream group are updated; At least two data streams correspond to the same network slice and / or DNN; The at least one of the policy information related to QoS monitoring of the at least two data streams is the same.

[0062] Here, the policy information includes at least one of a reporting frequency, a reporting period, and a reporting route.

[0063] Here, when the URSP corresponding to at least one data stream in a data stream group is changed, the URSPs corresponding to other data streams in the data stream group are also updated, thereby ensuring that the network slices selected by a data stream group or a group of data streams are the same, or that the data stream group or a group of data streams are carried in the same PDU session.

[0064] In one embodiment, the first network policy comprises: If at least two data streams correspond to different network slices, updating the URSP and / or the URSP priority and / or the network slice selection policy corresponding to the data streams; and / or When at least two data streams correspond to different network slices, supporting cooperative transmission of the at least two data streams on different network slices.

[0065] Here, by updating the URSP and / or URSP priority and / or network slice selection policy corresponding to the data stream, it is possible to ensure that the at least two data streams correspond to one network slice.

[0066] An embodiment of the present application further provides an information processing method applied to a second network device, and as shown in FIG. 2, the method includes the following steps:

[0067] In step 201, a first network policy is received.

[0068] In step 202, the first network policy is distributed to at least one terminal.

[0069] As noted above, in one embodiment, the first network policy is: that at least two data streams are carried by the same PDU session; The network slice selection policies or URSPs of at least two data streams are the same; When the URSP corresponding to at least one data stream in a data stream group is changed, the URSPs corresponding to other data streams in the data stream group are updated; At least two data streams correspond to the same network slice and / or DNN; The policy information related to QoS monitoring of the at least two data streams is the same, and includes at least one of the following: a reporting frequency, a reporting period, and a reporting path.

[0070] In one embodiment, the first network policy comprises: If at least two data streams correspond to different network slices, updating the URSP and / or the URSP priority and / or the network slice selection policy corresponding to the data streams; and / or When at least two data streams correspond to different network slices, supporting cooperative transmission of the at least two data streams on different network slices.

[0071] An embodiment of the present application further provides an information processing method applied to a third network device, as shown in FIG. 3, the method includes the following steps:

[0072] In step 401, at least two data streams are transmitted to a first UPF.

[0073] Here, the first UPF represents a UPF with packet granularity cooperation capability, and the at least two data streams are transmitted based on a first network policy.

[0074] As noted above, in one embodiment, the first network policy is: that at least two data streams are carried by the same PDU session; The network slice selection policies or URSPs of at least two data streams are the same; When the URSP corresponding to at least one data stream in a data stream group is changed, the URSPs corresponding to other data streams in the data stream group are updated; At least two data streams correspond to the same network slice and / or DNN; The policy information related to QoS monitoring of the at least two data streams is the same, and includes at least one of the following: a reporting frequency, a reporting period, and a reporting path.

[0076] In one embodiment, transmitting the at least two data streams to the first UPF includes: When at least one terminal initiates a PDU session or a PDU session update, the method includes transmitting at least two data streams to the first UPF.

[0077] Here, the at least one terminal represents a transmitting terminal of the at least two data streams.

[0078] In one embodiment, a UPF with packet granularity coordination capability refers to a UPF with the capability to synchronously process different data packets corresponding to the same time in at least two data streams.

[0079] Here, after the terminal receives the updated first policy, when the terminal initiates a PDU session or PDU session update, the third network device needs to search for a UPF with packet granularity coordination function in interaction with the N4 interface. Specifically, the third network device transmits the at least two data streams to the first UPF. In this way, the first UPF can coordinate between the at least two data streams based on packet granularity labels and synchronously process different data packets corresponding to the same time in the at least two data streams to achieve the purpose of multi-data stream coordination.

[0080] In conjunction with the above embodiment, Fig. 4 shows an application example applied to the above embodiment, in which the AF adds first information to a service parameter create / update / delete request (Nnef_ServiceParameter_Create / Update / Delete Request) sent to the NEF, and the UDR writes the first information to the PCF in a Nudr_DM_Notify sent to the PCF, and then delivers the updated URSP to the terminal.
