[0012] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0013] Summary of the Invention

[0014] A multimodal service is a communication service consisting of multiple data streams that are related to each other and coordinated by applications. The data streams can carry different types of data (e.g., audio, video, positioning, tactile data) and can come from different sources (e.g., a single UE, a single device, or multiple devices connected to a single UE or multiple UEs).

[0015] For the case of a single UE, these data flows are expected to be closely related and require strong application coordination to correctly execute multimodal applications, therefore, all these data flows are transmitted in a single Protocol Data Unit (PDU) session.

[0016] The Application Function (AF) can provide a Multi-modal Service ID to the Policy Control Function (PCF) as a clear indication that the application traffic is associated with a multimodal service. The Policy and Charging Control (PCC) can use this information to derive the correct PCC rules and apply Quality of Service (QoS) policies for data flows that are part of a specific multimodal application. Multimodal services are carried in a single PDU session on a terminal device (e.g., UE).

[0017] The inventors of the present application have discovered that the perception of multimodal services on the Radio Access Network (RAN) side has not been resolved. As a result, the access network cannot know the information of the multimodal services and thus cannot meet the Quality of Service (QoS) requirements of the multimodal services.

[0018] Embodiments of the present application provide a method, apparatus, and communication system for configuring multimodal service-related information, which solves the problem of how the access network side perceives multimodal service information by enhancing the relevant processes from the core network to the RAN (including RAN nodes and / or terminal devices).

[0019] According to one aspect of an embodiment of the present application, a device for configuring multimodal service-related information is provided, which is applied to an access network node. The device includes a first processing unit that controls the access network node to cause the access network node to perform the following operations:

[0020] Receive a protocol data unit (PDU) session resource establishment request message sent by an access and mobility management function (AMF) device, where the protocol data unit session resource establishment request message includes multimodal service related information in the protocol data unit (PDU) session.

[0021] According to another aspect of an embodiment of the present application, there is provided an apparatus for configuring multimodal service-related information, which is applied to a terminal device. The apparatus includes a second processing unit that controls the terminal device to cause the terminal device to perform the following operations:

[0022] A non-access stratum (NAS) message sent by an access and mobility management function (AMF) is received, where the non-access stratum (NAS) message includes information related to a multimodal service in a protocol data unit (PDU) session.

[0023] According to another aspect of an embodiment of the present application, a device for configuring multimodal service-related information is provided, which is applied to an access and mobility management function (AMF) device, the device including a third processing unit that controls the access and mobility management function (AMF) device to cause the access and mobility management function (AMF) device to perform the following operations:

[0024] receiving a protocol data unit (PDU) session resource establishment request message sent by a terminal device; and

[0025] A protocol data unit (PDU) session resource establishment request message is sent to an access network node, where the protocol data unit session resource establishment request message includes multimodal service related information in the protocol data unit (PDU) session.

[0026] The beneficial effect of the embodiments of the present application is that the access network side can perceive multimodal service information.

[0057] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0058] Figure 1 is a schematic diagram of the communication system of the present application, which schematically illustrates a situation taking a terminal device and a network device as an example. As shown in Figure 1, the communication system 100 may include a network device 101 and a terminal device 102 (for simplicity, Figure 1 only illustrates one terminal device as an example).

[0059] In the embodiment of the present application, existing services or future services can be carried out between the network device 101 and the terminal device 102. For example, these services include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), XR and media service communications, etc.

[0060] The terminal device 102 may send data to the network device 101, for example, using an authorized or unauthorized transmission mode. The network device 101 may receive data sent by one or more terminal devices 102 and provide feedback to the terminal device 102, such as ACK / NACK information. The terminal device 102 may confirm the end of the transmission process, or may continue with new data transmission, or may retransmit the data based on the feedback information.

[0061] The application function (AF), policy control function (PCF), session management function (SMF), and access and mobility management function (AMF) described in the various embodiments of this application are all network functions of the core network. Each function can be represented as a module or device that performs the function. For example, the access and mobility management function (AMF) can also be represented as an access and mobility management function (AMF) device.

[0062] Embodiments of the first aspect

[0063] An embodiment of the first aspect of the present application provides a method for configuring multimodal service related information.

[0064] After the Policy Control Function (PCF) obtains the Multi-modal Service ID and related service information provided by the Application Function (AF), the PCF can provide the policy information to the Session Management Function (SMF) as a clear indication that the application traffic is related to the multi-modal service.

[0065] In this application, in order to enable the radio access network (RAN) side to obtain multimodal service information, the SMF can provide the multimodal service identifier and related service information to the terminal device (e.g., UE) through the access and mobility management function (AMF) using the N1 reference point. The SMF can also provide the multimodal service identifier and related service information to the access network (e.g., access network node) through the AMF using the N2 reference point.

[0066] In each embodiment of the present application, the access network node may also be referred to as a network node, a base station or a RAN node, for example, the network device 101 in FIG. 1 ; the terminal device may be, for example, the terminal device 102 in FIG. 1 .

[0067] Figure 2 is a flowchart for implementing the AMF's configuration of multimodal service identifiers and related information for UEs and RAN nodes. Figure 2 illustrates the signaling process between the AMF, RAN nodes, and UE. The signaling process from the AMF to other core network functions, such as the SMF, is simplified and omitted. Figure 2 enhances the UE-initiated PDU session establishment process.

[0068] In this application, as shown in Figure 2, the process of AMF configuring the multimodal service identity and related information for the UE and RAN node may include the following operations:

[0069] 1. The UE makes a PDU Session Establishment Request to the AMF via a Non-Access Stratum (NAS) message. The request contains information to be forwarded to the SMF.

[0070] 2.AMF performs a series of interactions with other network functions of the core network (such as SMF selection, etc.).

[0071] 3. The AMF sends a PDU Session Establishment Request for the N2 reference point to the RAN node (base station, network node). This request message contains information about the multimodal services that may exist in the PDU session, which is generated by the SMF. This request message also includes a NAS message to be forwarded to the UE. This NAS message contains information about the multimodal services that may exist in the PDU session. The NAS message is included in the N2 PDU Session Establishment Request via a container and is transparently transmitted to the UE through the RAN node.

[0072] 4. The RAN node performs access network-specific resource setup for the UE, configuring the UE via a Radio Resource Control (RRC) message. The RRC message carries the NAS message sent by the AMF to the UE. This NAS message is the PDU Session Establishment Accept message sent by the AMF, which contains information related to multimodal services.

[0073] 5. The RAN node sends an N2PDU session response to the AMF, indicating that the resources required for the PDU session have been established.

[0074] Figure 3 is a schematic diagram of a method for configuring multimodal service related information in an embodiment of the first aspect, which is applied to an access network node. The method shown in Figure 3 is used to illustrate the content related to the access network node in Figure 2.

[0075] As shown in FIG3 , the method for configuring multimodal service related information includes:

[0076] 301. The access network node receives a protocol data unit (PDU) session resource establishment request message and / or a protocol data unit (PDU) session resource modification request message sent by an access and mobility management function (AMF) device, where the protocol data unit (PDU) session resource establishment request message and / or the protocol data unit (PDU) session resource modification request message include information related to multimodal services in the protocol data unit (PDU) session.

[0077] The content of the protocol data unit (PDU) session resource establishment request message in operation 301 corresponds to the relevant content in operation 3 of FIG. 2 .

[0078] The protocol data unit (PDU) session resource establishment request message in operation 301 is, for example, a PDU session establishment request message of an N2 reference point.

[0079] The protocol data unit (PDU) session resource establishment request message also includes a non-access stratum (NAS) message, which includes information related to the multimodal service in the protocol data unit (PDU) session. The non-access stratum (NAS) message is included in the request message via a container.

[0080] As shown in FIG3 , the method for configuring multimodal service related information further includes:

[0081] 302. The access network node establishes access network-specific resources for the terminal device, wherein the terminal device is configured through a radio resource control (RRC) message.

[0082] Operation 302 corresponds to operation 4 of FIG. 2 .

[0083] For example, in operation 302, the radio resource control (RRC) message carries a non-access stratum (NAS) message in a protocol data unit (PDU) session resource establishment request message, and the non-access stratum (NAS) message is a protocol data unit (PDU) session establishment accept (PDU Session Establishment Accept) message sent by the access and mobility management function (AMF) device.

[0084] In addition, in operation 301, the access network node may also receive a protocol data unit (PDU) session resource modification request message. For example, after the PDU session is established, the access network node may also receive other messages from the AMF, such as a PDU session resource modification request message. The PDU session resource modification request message includes a NAS message, which is a protocol data unit session modification command (PDU SESSION MODIFICATION COMMAND) message. The protocol data unit (PDU) session resource modification request message may be carried by a next generation application protocol (NGAP) message.

[0085] As shown in FIG3 , the method for configuring multimodal service related information further includes:

[0086] 303. The access network node performs at least one of data transmission synchronization, collaboration, and protocol data unit set (PDU Set) discarding operations between quality of service (QoS) flows with the same multimodal service related information.

[0087] As a result, at least one of data transmission synchronization, collaboration, and protocol data unit set (PDU Set) discarding operations between quality of service (QoS) flows with the same multimodal service related information can be performed, thereby supporting multimodal services.

[0088] Next, the message enhancement between the AMF and the RAN node involved in operation 301 is described.

[0089] In some embodiments, the enhancement to the N2PDU session request message in operation 301 may be an enhancement of a Next Generation Application Protocol (NGAP) message, that is, the N2PDU session request message may be carried by a Next Generation Application Protocol (NGAP) message.

[0090] Specifically, the PDU SESSION RESOURCE SETUP REQUEST message can be enhanced to include N2PDU session management information, such as a PDU session identifier, one or more QoS Flow Identifiers (QFIs), and a QoS Profile. For example, a QoS parameter can be added to the QoS Profile. For each multimodal QoS flow, its QoS Profile can include a QoS parameter (i.e., a first parameter), such as a multi-modal service identifier (Multi-modal Service ID).

[0091] When an access network node receives a PDU session resource establishment request message, it can obtain the multimodal information of the QoS flow through the configured first parameter. For example, if a QoS flow is configured with the first parameter, it means that the QoS flow belongs to a multimodal service, and its service identifier is indicated by the first parameter; if multiple QoS flows are configured with the same first parameter, it means that these multiple QoS flows belong to the same multimodal service.

[0092] In some embodiments, the first parameter may be added to a PDU Session Resource Setup Request Transfer information element in a PDU Session Resource Setup Request message, where the information element is a container. For example, the first parameter may be added to a QoS Flow Setup Request Item information element in the PDU Session Resource Setup Request Transfer information element.

[0093] Table 1 shows an example of adding a first parameter to a PDU Session Resource Setup Request Transfer information element.

[0094] Table 1

[0095] Protocol data unit session resource establishment request transfer information element

[0096] Similarly, when the SMF modifies the PDU session resources of the RAN through the AMF, the multimodal related information of the QoS flow can also be modified, that is, the multimodal service identifier of the QoS flow can be reconfigured. The PDU session resource modification request (PDU SESSION RESOURCE MODIFY REQUEST) message can be enhanced. Similarly, a first parameter can be added to the PDU Session Resource Modify Request Transfer information element in the PDU Session Resource Modify Request message, which is a container. For example, the first parameter is added to the QoS Flow Add or Modify Request Item IE in the Protocol Data Unit Session Resource Modify Request Transfer information element.

[0097] An example of adding the first parameter in the protocol data unit session resource modification request transmission information element is shown in Table 2.

[0098] Table 2

[0099] Protocol Data Unit Session Resource Modification Request Transfer Information Element

[0100] In other embodiments, the first parameter may also be placed as a QoS flow-level QoS parameter in a QoS Flow Level QoS Parameters IE, that is, the first parameter may be configured in the QoS Flow Level QoS Parameters IE. Thus, the multimodal service identifier of each QoS flow may be configured in the QoS Flow Level QoS Parameters IE.

[0101] Among them, the service quality flow level service quality parameter information element (QoS Flow Level QoS Parameters IE) can be included in the service quality flow establishment request item information element (QoS Flow Setup Request Item IE) in the PDU session resource establishment request message, and / or the service quality flow add or modify request item information element (QoS Flow Add or Modify Request Item IE) in the PDU session resource modification request message.

[0102] An example of adding the first parameter to the quality of service flow-level quality of service parameter information element is shown in Table 3.

[0105] Embodiments of the second aspect

[0106] An embodiment of a second aspect of the present application provides a method for configuring multimodal service related information, which is applied to a terminal device, such as the terminal device 102 shown in FIG1 .

[0107] FIG4 is a schematic diagram of a method for configuring multimodal service-related information according to an embodiment of the second aspect. The method shown in FIG4 is used to illustrate the content related to the terminal device in FIG2 .

[0108] As shown in FIG4 , the method for configuring multimodal service related information includes:

[0109] 401. Receive a non-access stratum (NAS) message sent by an access and mobility management function (AMF), where the non-access stratum (NAS) message includes information related to a multimodal service in a protocol data unit (PDU) session.

[0110] In operation 401 , the non-access stratum (NAS) message is a protocol data unit (PDU) session establishment accept message and / or a protocol data unit session modification command (PDU SESSION MODIFICATION COMMAND) message.

[0111] Operation 401 corresponds to operations 3 and 4 of FIG. 2 .

[0112] As shown in FIG4 , the method for configuring multimodal service related information further includes:

[0113] 402. The terminal device performs at least one of data transmission synchronization, collaboration, and protocol data unit set (PDU Set) discarding operations between quality of service (QoS) flows with the same multimodal service related information.

[0114] As a result, at least one of data transmission synchronization, collaboration, and protocol data unit set (PDU Set) discarding operations between quality of service (QoS) flows with the same multimodal service related information can be performed, thereby supporting multimodal services.

[0115] Below, the message enhancement between the AMF and the terminal device (e.g., user equipment UE) involved in operation 401 and operations 3 and 4 of Figure 2 is explained.

[0116] In the present application, the non-access stratum (NAS) message in operation 401 is enhanced, and the NAS message is included in the N2PDU session resource establishment request message or the N2PDU session resource modification message as an N1 session management container. For example, the PDU SESSION ESTABLISHMENT ACCEPT message in the enhanced NAS message includes QoS flow information in the PDU session, such as QoS rules, and QoS parameters of the QoS flow level associated with these QoS rules. The enhancement method is to add a first parameter to the QoS flow in the PDU session establishment accept message, which is used to indicate the multimodal service identifier of the QoS flow. In the present application, the first parameter can be added to the QoS flow in the PDU session establishment accept message by at least one of the following two methods.

[0117] Method 1: In method 1, the first parameter may be a parameter in the quality of service (QoS) parameter. For example, the first parameter may be used as a new QoS parameter for the QoS flow, that is, the first parameter may be added to the existing QoS parameters. The first parameter is, for example, a multi-modal service identifier (Multi-modal Service ID). For each multi-modal QoS flow, if the first parameter is configured, it indicates that it belongs to a multi-modal service and the first parameter indicates the multi-modal service identifier. For an explanation of the first parameter, reference may be made to the relevant explanation in the embodiment of the first aspect.

[0118] When a terminal device (e.g., UE) receives a NAS message indicating that a PDU session has been established, it can obtain the multimodal information of the QoS flow through the configured first parameter. For example, if a QoS flow is configured with the first parameter, it indicates that the QoS flow belongs to a multimodal service, and its service identifier is indicated by the first parameter; if multiple QoS flows are configured with the same first parameter, it indicates that these multiple QoS flows belong to the same multimodal service.

[0119] In the present application, the first parameter may be configured in a QoS flow descriptions IE in a PDU session establishment accept message. The name of the QoS flow descriptions IE may be, for example, Authorized QoS flow descriptions IE.

[0120] Specifically, the first parameter is configured in a parameter list in a quality of service flow description (QoS flow description) in an authorized quality of service flow description information element (Authorized QoS flow descriptions IE).

[0121] Figure 5 illustrates the format of parameters in the parameter list of a QoS flow description. As shown in Figure 5, the numbers 1 to 8 represent the eight bits of a byte. The parameter format includes the parameter identifier, the length of parameter contents, and the parameter contents.

[0122] The first parameter can be added to the parameter list, that is, a new parameter type can be added. In this way, the first parameter can still use the parameter format of Figure 5, where: the parameter identifier of the first parameter can be 1 plus the existing maximum parameter identifier, for example, 08H; the parameter content of the first parameter is 1 byte in length; and the parameter content of the first parameter is the multimodal service identifier to which the QoS flow belongs.

[0123] Table 4 below is an example of enhancements to the standard.

[0124] Table 4

[0125] Similarly, the first parameter can also be included in the NAS message Protocol Data Unit Session Modification Command (PDU SESSION MODIFICATION COMMAND) message, which is used by the core network (AMF) to modify the PDU session configuration of the terminal device, that is, the first parameter in the PDU session can be modified. The NAS message is included in the N2PDU session resource modification message as a container. The method of including the first parameter is the same as the above method. For example, the first parameter is placed in the parameter list in each QoS flow description in the QoS flow descriptions IE in the PDU session modification command message. Among them, the name of the QoS flow descriptions IE is called Authorized QoS flow descriptions.

[0126] If the terminal device obtains the multimodal service related information through the application layer information, it can also actively modify the first parameter and notify the core network through the NAS message. For example, the method shown in Figure 4 can also include the following operation 403:

[0127] 403. The terminal device sends a protocol data unit session modification request (PDU SESSION MODIFICATION REQUEST) message to the AMF to request modification of the first parameter.

[0128] In operation 403, a modification request for the first parameter is made by sending a PDU SESSION MODIFICATION REQUEST message to the AMF. That is, the first parameter may be included in the PDU session modification request. The method of including the first parameter is the same as the above method. For example, the first parameter is placed in the parameter list of each QoS flow description in the QoS flow descriptions IE (the IE name in the message is called Requested QoS flow descriptions) in the PDU session modification request message.

[0129] Method 2: In method 2, the first parameter may be a parameter in a Quality of Service (QoS) criterion. That is, the QoS criterion sent by each access network node to the terminal device may include: an indication indicating whether the QoS criterion is the default QoS criterion; a QoS criterion identifier; a QoS flow identifier; optionally, a series of packet filters; optionally, a multimodal service identifier (i.e., the first parameter); and a priority value.

[0130] In some embodiments of method 2, the first parameter can be placed in each quality of service rule (QoS rule) in the quality of service rule information element (QoS rules IE) in the PDU session establishment accept message, where the name of the quality of service rule information element (QoS rules IE) in the message is called authorized quality of service rules (Authorized QoS rules).

[0131] For example, the existing quality of service rule (QoS rule) field can be enhanced. Figure 6 is a schematic diagram of the enhanced quality of service rule field. As shown in Figure 6, a byte can be added to the end of the existing quality of service rule (QoS rule) field to include a first parameter, such as a multi-modal service identifier (Multi-modal Service ID); in addition, the reserved (spare) bit in the QoS rule (for example, the first bit of the last byte of the existing QoS rule field) can be used to indicate whether the QoS rule includes the first parameter. If the bit is 1, it means that the QoS rule includes the first parameter; otherwise, it does not.

[0132] In addition, the QoS rule field in Figure 6 may also include: a rule operation code; an indication indicating whether the QoS rule is the default QoS rule, that is, a default quality of service rule bit (DQR bit); a QoS rule identifier; a QoS flow identifier (QFI); the number of packet filters; the packet filter list; and a priority value, for example, a QoS rule precedence.

[0133] For another example, the Length of QoS rule field can be used to implicitly indicate whether the first parameter exists. When the terminal device parses the QoS rule, if all QoS rule parameters except the first parameter have been parsed, and one byte is left based on the QoS rule length, then the byte is the content of the first parameter.

[0134] Similarly, the first parameter can also be included in the protocol data unit session modification command (PDU SESSION MODIFICATION COMMAND) message, which is used by the AMF to modify the PDU session configuration of the terminal device, that is, the first parameter in the PDU session can be modified. The method of including the first parameter is the same as the above method, that is, the first parameter can be placed in each QoS rule in the QoS rules IE (the IE name in the message is called Authorized QoS rules) in the PDU session modification command message.

[0135] In some embodiments of method 2, if the terminal device obtains information related to the multimodal service through information at the application layer, it can also actively modify the first parameter. It is necessary to send a protocol data unit session modification request (PDU SESSION MODIFICATION REQUEST) message to the core network to request the modification of the first parameter. The method of including the first parameter is the same as the above method. For example, the first parameter is placed in each QoS rule in the QoS rules IE (the IE name in the message is called Requested QoS rules) in the PDU session modification request message.

[0136] In the present application, through the embodiments of the first aspect and the second aspect, the signaling from the core network to the terminal device and from the core network to the access network node is enhanced, so that the terminal device and the access network node can obtain multimodal information about the QoS flow, so that the uplink and downlink XR services can be coordinated between the QoS flows, and the QoS flows with the same first parameters can be synchronized and collaborated, and the protocol data unit set (PDU Set) discard operations between the QoS flows can be performed, etc., thereby supporting multimodal services.
