The present disclosure is in the field of wireless communications, and more specifically, pertains to a network slice customer (NSC) service identifier (ID) and a user equipment (UE) route selection policy (URSP) for network slice as a service (NSaaS).
Mobile communication in the next generation wireless communication system, 5G, or new radio (NR) network will provide ubiquitous connectivity and access to information, as well as ability to share data, around the globe. 5G networks and network slicing will be a unified, service-based framework that will target to meet versatile and sometimes, conflicting performance criteria and provide services to vastly heterogeneous application domains ranging from Enhanced Mobile Broadband (eMBB) to massive Machine-Type Communications (mMTC), Ultra-Reliable Low-Latency Communications (URLLC), and other communications. In general, NR will evolve based on third generation partnership project (3GPP) long term evolution (LTE)-Advanced technology with additional enhanced radio access technologies (RATs) to enable seamless and faster wireless connectivity solutions. A concern in network slicing as a service (NSaaS) is ensuring user privacy while also enabling policy management operations are seamless for data traffic in order to meet the demand for increase in traffic for larger bandwidth, lower latency, and higher data rates.
It is well understood that the use of personally identifiable information should follow privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. In particular, personally identifiable information data should be managed and handled so as to minimize risks of unintentional or unauthorized access or use, and the nature of authorized use should be clearly indicated to users.
The present disclosure will now be described with reference to the attached drawing figures, wherein like (or similarly ending) reference numerals are used to refer to like elements throughout, and wherein the illustrated structures and devices are not necessarily drawn to scale. As utilized herein, terms “component,” “system,” “interface,” and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor (e.g., a microprocessor, a controller, or other processing device), a process running on a processor, a controller, an object, an executable, a program, a storage device, a computer, a tablet PC and/or a user equipment (e.g., mobile phone, etc.) with a processing device. By way of illustration, an application running on a server and the server can also be a component. One or more components can reside within a process, and a component can be localized on one computer and/or distributed between two or more computers. A set of elements or a set of other components can be described herein, in which the term “set” can be interpreted as “one or more.”
Further, these components can execute from various computer readable storage media having various data structures stored thereon such as with a module, for example. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network, such as, the Internet, a local area network, a wide area network, or similar network with other systems via the signal).
As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, in which the electric or electronic circuitry can be operated by a software application or a firmware application executed by one or more processors. The one or more processors can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts; the electronic components can include one or more processors therein to execute software and/or firmware that confer(s), at least in part, the functionality of the electronic components.
Use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Furthermore, to the extent that the terms “including”, “includes”, “having”, “has”, “with”, or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.” Additionally, in situations wherein one or more numbered items are discussed (e.g., a “first X”, a “second X”, etc.), in general the one or more numbered items can be distinct or they can be the same, although in some situations the context can indicate that they are distinct or that they are the same.
As used herein, the term “circuitry” can refer to, be part of, or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), or associated memory (shared, dedicated, or group) operably coupled to the circuitry that execute one or more software or firmware programs, a combinational logic circuit, or other suitable hardware components that provide the described functionality. In some embodiments, the circuitry can be implemented in, or functions associated with the circuitry can be implemented by, one or more software or firmware modules. In some embodiments, circuitry can include logic, at least partially operable in hardware.
In consideration of various concerns for ensuring user privacy and data traffic management, a traffic descriptor can be configured to enable a network device (e.g., an end user device, user equipment (UE), base station, next generation NodeB (gNB), eNB, core network component, or other network component) to link a particular application service to a designated network slice (network slice instance) without impacting user privacy. In particular, a UE can receive a network slice customer (NSC) Service ID from an NSC such as a service provider of an application, wireless service, 3GPP provider, or the like. The NSC Service ID can identifier the NSC with a particular service once the NSC has obtained or received assignment to a network slice or network slice instance for control and management. The UE can further receive a UE route selection policy (URSP) with a traffic descriptor comprising the NSC Service ID or a component thereof and a rule that associates the NSC Service ID with a single network slice selection assistance information (S-NSSAI) for the network slice instance. The UE can then route data for an application with an application ID to the network slice assigned to the NSC for the particular service associated with the NSC Service ID of the NSC. Additional aspects and details of the disclosure are further described below with reference to figures.
The UPF 102 can act as an anchor point for intra-RAT and inter-RAT mobility, an external protocol data unit (PDU) session point of interconnect to DN 103, and a branching point to support multi-homed PDU session. The UPF 102 can also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, uplink (UL)/downlink (DL) rate enforcement), perform Uplink Traffic verification (e.g., Service Data Flow (SDF) to Quality of Service (QoS) flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 102 can include an uplink classifier to support routing traffic flows to a data network. The DN 103 can represent various network operator services, Internet access, or third-party services. DN 103 can include, or be similar to, an application server. The UPF 102 can interact with the SMF 124 via an N4 reference point between the SMF 124 and the UPF 102.
The AUSF 122 can store data for authentication of UE 101 and handle authentication-related functionality. The AMF 121 can be responsible for registration management (e.g., for registering UE 101, etc.), connection management, reachability management, mobility management, and lawful interception of AMF-related events, and access authentication and authorization. The AMF 121 can be a termination point for the N11 reference point between the AMF 121 and the SMF 124. The AMF 121 can provide transport for session management (SM) messages between the UE 101 and the SMF 124, and act as a transparent proxy for routing SM messages. AMF 121 can also provide transport for SMS messages between UE 101 and a Short Message Service (SMS) function (SMSF). AMF 121 can act as Security Anchor Function (SEAF), which can include interaction with the AUSF 122 and the UE 101, receipt of an intermediate key that was established as a result of the UE 101 authentication process. Where Universal Subscriber Identity Module (USIM) based authentication is used, the AMF 121 can retrieve the security material from the AUSF 122. AMF 121 can also include a Security Context Management (SCM) function, which receives a key from the SEAF that it uses to derive access-network specific keys. Furthermore, AMF 121 can be a termination point of a RAN CP interface or RAN connection point interface, which can include or be an N2 reference point between the (R)AN 210 and the AMF 121; and the AMF 121 can be a termination point of Non Access Stratum (NAS) layer (N1) signalling, and perform NAS ciphering and integrity protection.
AMF 121 can also support NAS signalling with a UE 101 over an N3 Interworking Function (IWF) interface. The N3 IWF can be used to provide access to untrusted entities. N3IWF can be a termination point for the N2 interface between the (R)AN 210 and the AMF 121 for the control plane, and can be a termination point for the N3 reference point between the (R)AN 210 and the UPF 102 for the user plane. As such, the AMF 121 can handle N2 signalling from the SMF 124 and the AMF 121 for PDU sessions and QoS, encapsulate/de-encapsulate packets for IPSec and N3 tunnelling, mark N3 user-plane packets in the uplink, and enforce QoS corresponding to N3 packet marking taking into account QoS requirements associated with such marking received over N2. N3IWF can also relay uplink and downlink control-plane NAS signalling between the UE 101 and AMF 121 via an N1 reference point between the UE 101 and the AMF 121, and relay uplink and downlink user-plane packets between the UE 101 and UPF 102. The N3IWF also provides mechanisms for IPsec tunnel establishment with the UE 101. The AMF 121 can exhibit a Namf service-based interface, and can be a termination point for an N14 reference point between two AMFs 121 and an N17 reference point between the AMF 121 and a 5G-Equipment Identity Register (EIR) (not shown by
The UE 101 can register with the AMF 121 in order to receive network services. Registration Management (RM) is used to register or deregister the UE 101 with the network (e.g., AMF 121), and establish a UE context in the network (e.g., AMF 121). The UE 101 can operate in an RM-REGISTERED state or an RM-DEREGISTERED state. In the RM-DEREGISTERED state, the UE 101 is not registered with the network, and the UE context in AMF 121 holds no valid location or routing information for the UE 101 so the UE 101 is not reachable by the AMF 121. In the RM-REGISTERED state, the UE 101 is registered with the network, and the UE context in AMF 121 can hold a valid location or routing information for the UE 101 so the UE 101 is reachable by the AMF 121. In the RM-REGISTERED state, the UE 101 can perform mobility Registration Update procedures, perform periodic Registration Update procedures triggered by expiration of the periodic update timer (e.g., to notify the network that the UE 101 is still active), and perform a Registration Update procedure to update UE capability information or to re-negotiate protocol parameters with the network, among others.
Connection Management (CM) can be used to establish and release a signaling connection between the UE 101 and the AMF 121 over the N1 interface. The signaling connection is used to enable NAS signaling exchange between the UE 101 and the CN 120, and comprises both the signaling connection between the UE and the Access Network (AN) (e.g., Radio Resource Control (RRC) connection or UE-N3IWF connection for non-3GPP access) and the N2 connection for the UE 101 between the AN (e.g., RAN or memory 230) and the AMF 121.
The SMF 124 can be responsible for SM (e.g., session establishment, modify and release, including tunnel maintain between UPF and AN node); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF over N2 to AN; and determining SSC mode of a session. SM can refer to management of a PDU session, and a PDU session or “session” can refer to a PDU connectivity service that provides or enables the exchange of PDUs between a UE 101 and a data network (DN) 103 identified by a Data Network Name (DNN). PDU sessions can be established upon UE 101 request, modified upon UE 101 and 5GC 110 request, and released upon UE 101 and 5GC 110 request using NAS SM signaling exchanged over the N1 reference point between the UE 101 and the SMF 124. Upon request from an application server, the 5GC 110 can trigger a specific application in the UE 101. In response to receipt of the trigger message, the UE 101 can pass the trigger message (or relevant parts/information of the trigger message) to one or more identified applications in the UE 101. The identified application(s) in the UE 101 can establish a PDU session to a specific DNN. The SMF 124 can check whether the UE 101 requests are compliant with user subscription information associated with the UE 101. In this regard, the SMF 124 can retrieve and/or request to receive update notifications on SMF 124 level subscription data from the UDM 127.
The NEF 123 can provide means for securely exposing the services and capabilities provided by 3GPP network functions for third party, internal exposure/re-exposure, Application Functions (e.g., AF 128), edge computing or fog computing systems, etc. In such embodiments, the NEF 123 can authenticate, authorize, and/or throttle the AFs. NEF 123 can also translate information exchanged with the AF 128 and information exchanged with internal network functions. For example, the NEF 123 can translate between an AF-Service-Identifier and an internal 5GC information. NEF 123 can also receive information from other network functions (NFs) based on exposed capabilities of other network functions. This information can be stored at the NEF 123 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 123 to other NFs and AFs, and/or used for other purposes such as analytics. Additionally, the NEF 123 can exhibit a Neff service-based interface.
The NRF 125 can support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 125 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like can refer to the creation of an instance, and an “instance” can refer to a concrete occurrence of an object, which can occur, for example, during execution of program code, wherein a job or measurement instance includes a particular task or measurement activity to measure any particular parameter, metric, related to a KPI for any of the NFs. Additionally, the NRF 125 can exhibit the Nnrf service-based interface.
The UDM 127 can handle subscription-related information to support the network entities' handling of communication sessions and can store subscription data of UE 101. For example, subscription data can be communicated between the UDM 127 and the AMF 121 via an N8 reference point between the UDM 127 and the AMF. The UDM 127 can include two parts, an application FE and a Uniform Data Repository (UDR) (the FE and UDR are not shown by
The NSSF 129 can select a set of network slice instances serving the UE 101. The NSSF 129 can also determine allowed NSSAI and the mapping to the subscribed single Network Slice Selection Assistance Information (S-NSSAls). The NSSF 129 can also determine the AMF set to be used to serve the UE 101, or a list of candidate AMF(s) 121 based on a suitable configuration and possibly by querying the NRF 125. The selection of a set of network slice instances for the UE 101 can be triggered by the AMF 121 with which the UE 101 is registered by interacting with the NSSF 129, which can lead to a change of AMF 121. The NSSF 129 can interact with the AMF 121 via an N12 reference point between AMF 121 and NSSF 129; and can communicate with another NSSF 129 in a visited network via an N31 reference point (not shown by
Additionally, there can be many more reference points and/or service-based interfaces between the NF services in the NFs; however, these interfaces and reference points have been omitted from

The CSC 302 can be configured to utilize communication services as, for example, a UE device 101, an end-user device, a tenant or a vertical. The CSC 302 can be provided service or a network slice by the CSP 304 as a client or further provide networking service or use of the network slice to the NSC 308.
The CSP 304 can be configured to provide communication services and builds/establishes its own communication services, in which it can govern or control. The CSP 304 can provide the communication service with or without a network slice, which can be a separate network that operates on physical hardware for different applications, services, or purposes by separating the control plane from user plane function. Each network slice can have its own architecture provisional management and security that supports one or more specific use cases. Functions such as speed, capacity, connectivity, and coverage can be allocated via the network slice to meet any requirements of a particular objection or primary purpose, for example. The CSP 304 can be a provider of a service by providing a network slice or a service to the CSC 302, NSC 308, or NSP 310, for example, in which as a provider can control the management and use of the network slice or service to an customer component such as an end-user, UE or other component device. The CSP 304 can also be a client to receive such management or control of network slicing from the NOP 306, for example, or other component of a CN 120, or the like.
The NOP 306 can provide a network slice or service to the CSC 302, the CSP 304, or the NSP 310, for example, as a provider. The NOP 306 can be configured to design, build, and operate its networks to offer related services to one or more clients, either directly or indirectly via communication interfacing. The NOP 306 can operate as a component of or be communicatively coupled to the CN 120 or a central entity, for example.
The NSC 308 can operate to obtain use of a network slice as a NSaaS by another component/device so that services can be utilized such as an application relying upon the service for operation (e.g., gaming, data streaming, augmented reality, or the like). For example, the NSC 308 can be configured as a client, an end-user device or UE, for example, that uses the network slice according to an assigned service.
The NSP 310 can further provide services or a network slice obtained from another component to the NSC 308. The NSP 310 can operate as a provider by further designing, building, operating, controlling, or managing a network slice or service in response to obtaining or being assigned the network slice or service. The NSP 310 can also be or comprise the NOP 306 to provide network slicing as a NSaaS.
NSaaS or Network Slice as a Service as defined in section 4.1.6 in 3GPP TS 28.530, and referred to herein, can be offered by the CSP 304 to its CSC 302 in the form of a service (e.g., gaming, augmented reality, data streaming, or the like). This service allows the CSC 302 to use the network slice instance as the end user or optionally allows the CSC 302 to manage the network slice instance as manager via a management interface exposed by the CSP 304, for example. In turn, the CSC 302 can play the role of the CSP 304 and offer their own services (e.g. communication services) on top of the network slice instance obtained from the CSP 304. For example, a network slice customer or NSC 308 can also play the role of NOP 306 and could build their own network containing the network slice obtained from the CSP 304 as a “building block”. In this model, both CSP 304 offering NSaaS and CSC 302 consuming NSaaS have the knowledge of the existence of network slice instances. Depending on the service offering, the CSP 304 offering NSaaS can impose limits on the NSaaS management capabilities exposure to the CSC 302, and the CSC 302 can manage the network slice instance according to NSaaS management capabilities exposed and agreed upon limited level of management by the CSP 304. Likewise, the NSP 310 can operate as a provider CSP 304 for the client NSC 308, or the CSC 302/NSC 308 can operate as a provider of the network slice to an end-user or UE device, for example.
A URSP can be used by the UE 401 to determine if a detected application (e.g., online gaming application, augmented reality application, data streaming application, or the like) can be associated to an established PDU Session, can be offloaded to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU Session. As such, the PDU session can operate as a logical connection between a UE 401 and a data network or network slice. A URSP can be pre-configured in the UE 402 or can be provisioned to UE 401 from the PCF 426 using a transparent container included in a NAS transport message, such as signals 411 thru 414. The signal message 411 comprises a PCF request delivery of a URSP policy, signal message 412 comprises a downlink (DL) NAS transport in a UE policy container from the AMF 421 to the RAN 410, and the signal message 414 is a radio resource control message with the message 412. In response to receiving the UE policy, the UE 401 can then provide the message 416 comprising an RRC message UL NAS transport UE policy container. The RAN 410 receives the message 416 and provides an uplink message 418 as a UL NAS Transport UE policy container policy RSP message.
A URSP rule includes one traffic descriptor that specifies the matching criteria and one or more of the route selection descriptors, which define the parameters of the PDU session to be used to transfer the traffic data. The traffic descriptor contains one or more of the following components: application identifiers, IP 3 tuples, non-IP descriptors, data network names (DNNs), connection capabilities and domain descriptors, i.e. destination fully qualified domain name(s) (FQDN(s)). According to embodiments or aspects herein, the traffic descriptor can include an NSC Service ID. A route selection descriptor can contain multiple elements (e.g., a PDU session type, a session and service continuity (SSC) mode, S-NSSAls or DNNs.
The URSP can be evaluated by the UE 401 as is referenced in 3GPP TS 23.503, for example. For every newly detected application the UE 401 can evaluate the URSP rules in an order of rule precedence and determine if the application is matching the traffic descriptor of a URSP rule. When a URSP rule is determined to be applicable for a given application (see clause 6.6.2.1), the UE 401 can select a route selection descriptor within this URSP rule in the order of a route selection descriptor precedence. When a valid route selection descriptor is found, the UE 401 determines if there is an existing PDU Session that matches all components in the selected route selection descriptor. When a matching PDU Session exists, the UE 401 associates the application to the existing PDU Session by routing the traffic of the detected application on this PDU Session. If none of the existing PDU Sessions matches, the UE 101 can try to establish a new PDU Session using the values specified by the selected route selection descriptor.
The following is an example of URSP rule as clarified in Annex A in 3GPP TS 23.503:
Various concerns can be addressed according to aspects/embodiments herein. The application ID of an end user device or UE 101 (401) application is not shared with the network or the NSP, central operator or central core network entity in order to avoid impacting or preserving user privacy of the UE 101. A non-IP descriptor can be only used for applications transferred in a non-IP type PDU session. IP 3 tuples or the IP address of the application server is not necessarily unique and could be changed dynamically in a short time. A DNN is not mandatory that all application(s) in one DNN must use a same network slice. Consequently, a new or additional traffic descriptor element/component, referred to herein as an NSC Service ID can be configured to enable a network component to link an application to a correct slice without impacting user privacy of the UE or end user in particular.
The NSC Unique ID 504 can be obtained by the NSC, for example, from a global entity (e.g., 3GPP, a global system for mobile communications alliance (GSMA). This can be independent of a network slice provider (NSP 310), a network operator 306, or a core network 120 component. Alternatively, or additionally, the NSC 308 can obtain the NSC Service ID after negotiation with operator. At least a portion (e.g., the NSC Unique ID 504, the NSC Service ID 506, or the NSC Service ID 502 container) of the NSC Service ID 500 can be unique per operator or manager of the network slice. In this case, when the UE 101 or user device switches or changes the universal mobile telecommunication system (UMTS) subscriber identity module (USIM), a repeat of the registration/binding of the application to the specific NSC Service ID 502 of the NSC 308 can be performed. In one example, the NSC Unique ID 504 can be at least 16 bits.
The Service ID 506 can be assigned to a particular communication service or application service for an application to use the network slice. For example, the Service ID can designate that only online gaming operations/services. Other services or application operations can also be assigned to the Service ID and not are not necessarily limited to the example of online gaming. In an aspect, a single application service (e.g., online gaming, or other service) can be designated or assigned to the Service ID 506 so that one or a multiple of UEs/user devices can utilize the network slice according to the particular application ID of an application (e.g., game or other data application) for use of the particular service with the network slice obtained by the NSC 308. The Service ID can be assigned, negotiated or designated by the NSC 308 with the NSP 310 (as a network operator, or CN component) for association with the network slice, which can be reserved as dedicated resources (e.g., storage amount, bandwidth, processing power, attribute names and their definitions for a supported throughput in uplink or downlink, a delay, a coverage area of the slice, etc.) as isolated from other network slices, for example.
The UE 101, for example, can further receive the NSC Service ID 502 from the NSC and a URSP from a network operator as an NSP with the NSC Service ID as a traffic descriptor. The traffic descriptor can further comprise a rule for associating the NSC Service ID with an S-NSSAI to enable use of the correct network slice for the particular communication service for an application at the UE 101. The UE 101 thus does not have to share the App ID of the application with the NSP.
The NSP 606 can be configured to generate a URSP comprising a rule that links the NSC Service ID 500 (502) with an S-NSSAI of a network slice. This can be done in response to a communication from the NSC 602 requesting the network slice, or an assignment of an NSC Unique ID 502 or the NSC Service ID 502 to the NSC 602 for the network slice. This can be done without any communication by the UE 604 with the NSP 606, for example. In response to a request by the NSC 602 to the NSP 606 for a network slice, the NSP 606 can provide a network slice type (NEST) with the NSC Service ID 502 comprising the NSC Unique ID 504 and the Service ID 506. The NEST can define characteristics of the network sliced assigned to the NSC 602. Such characteristics can include attribute names, and their definitions for a supported throughput in uplink or downlink, a delay, a coverage area of the slice, or other dedicated resources, for example.
The NSP 606 can be configured to modify the URSP to comprise the NSC Server ID 502 or at least a portion thereof (e.g., NSC Unique ID 502, Service ID 504) as a valid traffic descriptor. The NSP 606 as an operator can be configured to add a rule in the URSP to link the NSC Service ID 502 to the S-NSSAI for linking traffic to the network slice assigned to the NSC 602. The following is an example of the URSP rule generated by the NSP 606 as an operator and provided to the UE 604 for association of the NSC Service ID to a network slice obtained by the NSC 602:
As state above, the URSP includes a traffic descriptor comprising the NSC Service ID and a rule that associates the NSC Service ID with an S-NSSAI that enables the UE 604 to route traffic to the network slice assigned to the NSC 602 in NSaaS based on the NSC Service ID and the S-NSSAI. The URSP rule in the URSP is provided to the UE 604 by the NSP 606, while the NSC Service ID is provided to the UE 604 by the NSC 602. The URSP rule is configured to associate traffic of the application to the NSC Service ID with the S-NSSAI, and can further comprise at least one of: a session and service continuity (SSC) mode, a preferred access type, or a data network name (DNN). In the present example, the DNN can indicate “internet”.
The UE 604 can determine whether the NSC Service ID from the NSC 602 is associated with an online gaming service based on a service ID of the NSC Service ID. The UE can further determine whether an application ID associated with an application or application service (e.g., an online gaming service, or other service) matches the URSP rule of the URSP in response to an initiation of the application or application service. Then the UE 604 can further determine whether an existing packet data unit session or PDU session matches a route selection descriptor of a traffic descriptor that comprises the NSC Service ID and the S-NSSAI, linking the two for a particular network slice identified by the NSC 602. In response to a determination that the NSC Service ID is associated with the service, a match of the application ID with the URSP rule of the URSP, and the existing PDU session matching the route selection descriptor, the UE can associate the application service (e.g., an online gaming service, data streaming, or other application service) to the existing PDU session on the network slice that is associated with the S-NSSAI.

The process flow initiates at 802 with receiving, from an NSP, a UE route selection policy (URSP) comprising a traffic descriptor that includes an NSC Service ID. At 804, the process flow 800 further comprises determining an application service derived from the NSC Service ID. At 806, the process flow 800 further comprises determining a single network slice selection assistance information (S-NSSAI) from the URSP.
