Description

Technical Field

[0001] The present invention generally relates to configuration mapping in mobile networks, and more particularly, the present invention relates to configuration mapping from a deterministic network to a 3GPP network. Background Art

[0002] Deterministic Networking (DetNet) is an initiative of the IETF DetNet Working Group to develop deterministic data paths for real-time applications that require very low data loss rates, minimal packet delay variation (jitter), and bounded latency. Examples of such applications include audio and video streaming, industrial automation, and vehicle control. DetNet networks are managed by a central controller called the Controller Plane Function (CPF) or DetNet Controller, which manages information about DetNet flows and their requirements.

[0003] Integration of the 3GPP 5G System (5GS) into the DetNet architecture is one aspect that 3GPP is targeting. The goal is to open up the 5G system as a DetNet node, as described in 3GPP TR 23.700-46.

[0004] A significant challenge in current solutions is the lack of methods to address interoperability between 5GS and DetNet networks. This limitation stems from the disjoint configuration domains of 5GS and DetNet, which hinders seamless interoperability between the two systems.

[0005] A problematic aspect of current solutions is the lack of a way to address interworking between 5GS and DetNet networks. This lack of interworking solutions prevents the two networks from achieving seamless communication and integration, which is critical for the effective operation of real-time applications with stringent requirements on data loss rates, jitter, and latency.

[0006] Another problematic aspect is the disjointness of the configuration domains between 5GS and DetNet. These disjoint configurations create compatibility issues and hinder the ability of the two systems to interwork effectively. As a result, it becomes challenging to establish a cohesive framework that enables seamless exchange of information and management of network resources between 5GS and DetNet systems. Summary of the invention

One or more additional instances of a network function (NF) may be incorporated into the network system.

[0028] The solution described in this article aims to enable 5GS to map the configuration provided by the DetNet controller to the 3GPP configuration.

[0029] Figure 2 A possible architecture for integrating 5GS into the DetNet network is shown in FIG. Figure 2 The DetNet controller that controls the DetNet network and the 5GS as a logical DetNet node (at each UPF granularity) are shown. In the control plane, the TSCTSF function represents the DetNet node.

[0030] TSCTSF uses the DetNet incoming and outgoing interfaces to determine the flow direction and the PDU sessions affected by the DetNet flow. TSCTSF maps the DetNet flow requirements and flow specifications to 3GPP QoS parameters.

[0031] The solution may include the following:

[0032] TSCTSF derives the required 5GS delay from the end-to-end delay based on the configuration, e.g. taking a given fraction of the end-to-end requirement and / or subtracting a constant corresponding to the rest of the network.

[0033] In addition to the end-to-end latency, the DetNet controller adds new parameters for the latency required in 5GS.

[0034] • TSCTSF calculates the required bandwidth based on the maximum packet length, the maximum number of packets per interval, and the time needed to deliver a packet (which may be a shorter value based on the configuration or traffic interval).

[0035] The DSCP value in the flow specification is provided to the PCF and taken into account in the 3GPP QoS mapping.

[0036] In the proposed solution, on the device side, the end host as a DetNet system can use the DetNet function. The end host does not have to be aware of DetNet.

[0037] The main principles of the solution may also include:

[0038] In the DetNet YANG model, the forwarding sublayer configuration and service profile can be used for mapping.

[0039] The forwarding sublayer configuration identifies the flow and the incoming and outgoing interfaces. Based on this information, the PDU session and flow direction (uplink, downlink or whether it is UE to UE) can be determined.

[0040] The DetNet service requirements in the service profile include maximum delay and maximum loss, which can be converted to 3GPP delay and PER requirements.

[0041] Regarding the YANG model, TSCTSF can derive per-5GS requirements based on the end-to-end requirements, or the DetNetYANG model can be extended to 5GS to also include 5GS-specific requirements.

[0042] DetNet service specifications are used to determine the periodicity and bandwidth requirements of the flow.

[0043] The DetNet YANG model outlines the parameters required for DetNet node configuration. 5GS focuses on the forwarding sublayer configuration and service profiles, which include service requirements and specifications. The DetNet YANG model may contain service requirements that can be mapped to 3GPP parameters, such as maximum delay (required delay) and maximum loss (PER).

[0044] The traffic specification may include parameters such as interval (periodicity) and maximum pkts / maximum payload size per interval (maximum burst size), which may be used to calculate the required bandwidth (GFBR and MFBR).

[0045] TSCTSF can use intervals to generate periodic values ​​in TSCAI. However, the current DetNet YANG model only includes end-to-end service requirements, not per-node requirements. The two main options for 5GS to act as a DetNet node are: (1) TSCTSF derives per-node service requirements based on end-to-end service requirements using pre-configured mappings based on deployment knowledge; (2) Extending the IETF YANG model with additional parameters for the 5GS system on a per-node basis. This can be achieved by defining a YANG model that imports the DetNet YANG model and adds the necessary per-node parameters.

[0046] TSCTSF can obtain the DetNet YANG forwarding configuration, which includes the incoming and outgoing interfaces. These interfaces are identified based on the reports from 5GS to the DetNet controller. The interface name is derived based on the if index, which is based on the port number set by the UPF. TSCTSF stores the mapping between port numbers (if index and corresponding interface name) and PDU sessions, thereby achieving PDU session identification. The incoming and outgoing interfaces also determine the flow direction (uplink / downlink and UE to UE).

[0047] The TSCTSF may verify that the 3GPP system routes a given flow according to the DetNet forwarding sublayer. The TSCTSF may accept or reject the DetNet configuration based on the optional verification. For UE-to-UE flows, if allowed, the TSCTSF may generate separate requests for uplink and downlink legs.

[0048] The PCF can receive DetNet parameters and flow identifiers determined by the DetNet configuration from the TSCTSF, which are mapped to flow descriptions sent to the PCF. The flow descriptions can be extended to accommodate DetNet requirements, including DSCP values, and optional IPv6 flow labels and IPsec SPIs. The PCF determines parameters based on the DetNet parameters and can establish or modify QoS flows as needed.

[0049] Advantageously, 5GS can act as a node in the DetNet system, so that 5GS can be applied to IP-based deterministic networks.

[0050] Further advantageously, the proposed solution does not require a NEF between the DetNet controller and the TSCTSF, since it is assumed that the DetNet controller is trusted by the operator and can influence the QoS of the traffic flows.

[0051] The present disclosure provides a method for configuration mapping in a communication network. The method includes: sending at least one first configuration parameter from a controller entity to a first network node; mapping the at least one first configuration parameter to at least one second configuration parameter at the first network node; sending the at least one second configuration parameter from the first network node to the second network node; and initiating a modification action in the communication network at the second network node. In some embodiments, the method also includes: sending success or failure information related to the configuration parameter and / or the configuration mapping from the second network node to the first network node, in particular, wherein the success or failure information is provided by a status code; and sending success or failure information related to the configuration parameter and / or the configuration mapping from the first network node to the controller entity, in particular, wherein the success or failure information is provided by a status code. In some embodiments, the method also includes: determining at least one user session affected by the at least one first configuration parameter at the first network node; and providing information about how to modify the at least one user session from the first network node to the second network node. In some embodiments, the method further comprises: determining at the first network node whether the service flow is an uplink service, a downlink service or a user terminal to user terminal service service flow information or flow direction information; and providing the service flow information or flow direction information from the first network node to the second network node. In some embodiments, the at least one first configuration parameter is related to the domain of the controller entity, and the at least one second configuration parameter is related to the domain of the communication network, in particular, wherein the domain of the controller entity is a deterministic network (DetNet) and the domain of the communication network is a 3GPP domain. In some embodiments, the at least one first configuration parameter is related to a YANG model, and the at least one second configuration parameter is related to a 3GPP model, in particular, wherein the YANG model is a DetNet YANG model, and the 3GPP model is related to 3GPP quality of service. In some embodiments, the at least one second configuration parameter is mapped on a per-network node basis. In some embodiments, the at least one first configuration parameter is a maximum delay, and the at least one second configuration parameter is a required delay. In some embodiments, the at least one first configuration parameter is a maximum loss, and the at least one second configuration parameter is a packet error rate (PER). In some embodiments, the at least one first configuration parameter is interval information and the at least one second configuration parameter is periodicity information. In some embodiments, the at least one first configuration parameter is a maximum payload size and / or a maximum number of packets per interval and the at least one second configuration parameter is a guaranteed stream bit rate (GFBR) and / or a maximum stream bit rate (MFBR).In some embodiments, the at least one first configuration parameter is any one of the following: maximum delay variation, maximum continuous loss tolerance, maximum disorder, differentiated service code point value, minimum number of packets per interval, and minimum payload size. In some embodiments, the modification action includes sending the at least one second configuration parameter to a third network node. In some embodiments, the modification action includes modifying the quality of service in the communication network, in particular, wherein modifying the quality of service includes establishing a new QoS flow or modifying an existing QoS flow, and in particular, wherein the modification is performed for a user session. In some embodiments, the user session is a PDU session and the user terminal is a user equipment (UE). In some embodiments, the controller entity is a DetNet controller, the first network node is a time-sensitive communication time synchronization function (TSCTSF), the second network node is a policy control function (PCF), and the third network node is a session management function (SMF).

[0052] The solution may include:

[0053] In the DetNet YANG model, the forwarding sublayer configuration and service profile are used for mapping.

[0054] The forwarding sublayer configuration identifies the flow and the incoming and outgoing interfaces. Based on this information, the PDU session and flow direction (uplink, downlink or whether it is UE to UE) can be determined.

[0055] • The DetNet service requirements in the service profile include maximum delay and maximum loss, which can be converted to 3GPP delay and PER requirements.

[0056] The YANG model currently defined in IETF only includes end-to-end service requirements. There are two options: TSCTSF can derive per-5GS requirements based on end-to-end requirements, or extend the DetNet YANG model for 5GS to also include 5GS-specific requirements.

[0057] DetNet service specifications are used to determine the periodicity and bandwidth requirements of the flow.

[0058] The DSCP value in the DetNet service specification can be used to provide priority to the PCF.

[0059] The following describes the parameters that can be sent from the DetNet controller.

[0060] The YANG model in IETF draft-ietf-detnet-yang describes the parameters used by DetNet nodes to set the configuration for DetNet. Since 5GS implements the forwarding sublayer, the forwarding sublayer configuration needs to be considered in the YANG model. In addition, the YANG configuration can provide a service profile, which includes service requirements and service specifications that can be used by the 5GS system.

[0061] The DetNet YANG model can include the following parameters in the service requirements, which can be mapped to 3GPP parameters.

[0062] Maximum latency, which is related to the latency required in 5GS.

[0063] Maximum loss, which is related to PER.

[0064] The DetNet YANG model may also contain other parameters that do not map directly to 3GPP parameters: Maximum Delay Variation, Maximum Consecutive Loss Tolerance, Maximum Out-of-Sequence. These parameters do not have a direct 3GPP mapping as their definitions differ from current 3GPP parameters. However, these parameters may be forwarded by the TSCTSF to the PCF to be considered when setting 3GPP QoS parameters.

[0065] The flow specification in the DetNet configuration may also contain a DSCP value. This value may also be provided to the PCF as an optional input to determine the QoS settings.

[0066] A business specification may include the following parameters that can be mapped:

[0067] • Interval: This corresponds to the periodicity in 3GPP systems.

[0068] Maximum pkts per interval, maximum payload size: Along with the interval parameters, these parameters can be used to calculate the average bandwidth required, which corresponds to the GFBR and MFBR. Both GFBR and MFBR can be set to the same value, or alternative calculation methods can be used. As another alternative, instead of reserving the average bandwidth, the actual bandwidth can be reserved, with a higher value to reflect the temporary burstiness of the service. For this reason, instead of the service periodicity, a hybrid maximum value can be used for the time required to deliver the service burst. This can also be determined based on the maximum delay that needs to be provided for the service.

[0069] The maximum burst size can be calculated by multiplying the maximum pkts per interval by the maximum payload size.

[0070] The service specification may also contain a minimum payload size and a minimum pkts per interval. However, these parameters may be forwarded to the PCF for consideration in QoS mapping or to verify that these constraints are adhered to in the actual service.

[0071] TSCTSF may use intervals to generate period values ​​in TSCAI.

[0072] Regarding business requirements, it is important to point out that the current DetNet YANG model only includes end-to-end business requirements (e.g., in terms of maximum latency), and not per-node requirements that a given node needs to achieve. Although per-node requirements are important for the configuration of a given node, as of now, this information is not currently included in the IETF model.

[0073] Based on the current IETF YANG model as currently defined, there are two main options for 5GS as a DetNet node:

[0074] Based on the knowledge of the given deployment, the TSCTSF derives the per-node service requirements from the end-to-end service requirements using pre-configured mappings in the TSCTSF. For example, taking a given portion of the end-to-end requirements and / or subtracting a constant corresponding to the rest of the network.

[0075] On a per-node basis, extend the IETF YANG model to have additional parameters applicable to 5GS systems. The YANG modeling language allows for extensibility. This can be achieved through a 3GPP defined YANG model that imports the IETF defined DetNet YANG model and adds the required per-node parameters. In this way, the model used by 5GS is still compatible with IETF DetNet, but allows the DetNet controller to provide service requirements on a per-node basis when the DetNet controller is prepared for this and when it knows that the DetNet node is a 5GS. In the Appendix below, an example module is shown for extending the IETF DetNet YANG model to have per-node values ​​for maximum delay and maximum loss for 5GS systems.

[0076] The following describes how the identification of a PDU session is performed.

[0077] The TSCTSF receives the DetNet YANG forwarding configuration, which involves an incoming interface and an outgoing interface. These are based on the interface identification provided in the report from the 5GS to the DetNet controller. The interface is identified by its name, which is derived from the if index, which in turn is based on the port number set by the UPF. The TSCTSF stores a mapping between port numbers (if index and corresponding interface name) and PDU sessions, so the PDU sessions can be identified. The incoming and outgoing interfaces also identify whether the flow is uplink or downlink, so the flow direction is known, and whether it is a UE-to-UE flow.

[0078] TSCTSF may also implement verification that the 3GPP system routes a given flow as defined in the DetNet forwarding sublayer. It may be verified in TSCTSF whether the incoming and outgoing interfaces in the DetNet configuration correspond to valid routes in the 3GPP system. For example, TSCTSF may verify whether the destination IP address in the downlink flow toward a given interface corresponding to a PDU session is the same IP address assigned for the same PDU session. As another example, TSCTSF may be configured with knowledge of whether UE-to-UE routing is enabled. TSCTSF may also verify other parameters of the configuration and reject the request based on the TSCTSF configuration if the configuration is outside the supported range. As a result of this optional verification, TSCTSF may decide to accept or reject a given DetNet configuration.

[0079] In case of UE-to-UE flow, if the system allows such service, the TSCTSF generates separate requests to the PCF for the uplink and downlink legs of the flow.

[0080] The configuration used for DetNet is described below.

[0081] The PCF receives the relevant DetNet parameters from the TSCTSF, as well as the identity of the flow as determined by the DetNet configuration, which is mapped to a flow description sent to the PCF. The Stage 3 definition of the flow description can be extended as needed by DetNet and also includes DSCP values ​​and optional IPv6 flow labels and IPsec SPI. The PCF determines the 3GPP parameters based on the DetNet parameters. The PCF can also consider the DSCP value in the flow description. The PCF can establish new QoS flows or modify existing QoS flows as needed.

[0082] The Network Open Function (NEF) can be placed between the DetNet Controller and the TSCTSF, for example, in the case where the DetNet Controller is not trusted by the operator. In this case, the NEF will act as an intermediate node for messages sent from the DetNet Controller to the TSCTSF (and vice versa). In addition, the NEF can implement any function of the DetNet Controller or the TSCTSF.

[0083] The present disclosure also provides a mobile network node, in particular, a second network node (111, 900), a first network node (116, 800), and a controller entity (700) configured to implement the corresponding methods described herein. In some embodiments, the second network node is a policy control function (PCF) 111. In some embodiments, the first network node is a time-sensitive communication time synchronization function (TSCTSF) 116. In some embodiments, the controller entity is a DetNet controller (DetNet controller).

[0084] The present disclosure also provides corresponding computer programs and computer program products, which include codes, for example in the form of computer programs, which when executed on a processing circuit of a mobile network node, cause the mobile network node to implement the disclosed method.

[0085] In the following, the drawings showing embodiments of the solution are described in detail.

[0086] Figure 3 is a signaling diagram showing the process for mapping of DetNet configuration. The process is implemented by the DetNet controller, TSCTSF and PCF.

[0087] In step 1, the DetNet Controller provides the YANG configuration to the TSCTSF. The TSCTSF uses the identification of the incoming and outgoing interfaces to determine the PDU sessions affected and whether the flow is uplink or downlink. The TSCTSF also determines if the flow is UE-to-UE, in which case both PDU sessions will be affected. The TSCTSF maps the configuration as described above and calculates the delay and PER requirements and the TSC auxiliary container.

[0088] In step 2, the TSCTSF provides the mapped parameters and flow description to the PCF.

[0089] In step 3, the PCF determines whether an existing QoS flow needs to be modified or a new QoS flow needs to be created based on the parameters received from the TSC TSF. In addition, the TSC auxiliary container is provided to the SMF.

[0090] In step 4, the PCF responds to the TSCTSF including information about the success of the configuration.

[0091] In step 5, the TSCTSF provides a response to the CPF regarding the result of the configuration setting. Optionally, if the requested configuration cannot be set, a 3GPP specific status code may be provided to provide additional information.
