The present application relates to the field of wireless technologies and, in particular, to user equipment routing selection policy traffic categories.
Third Generation Partnership Project (3GPP) networks provide for routing of traffic of user equipments (UEs) within the networks. In particular, traffic of the UEs may be routed to different resources within the networks to provide services for UEs. One approach for determining which resources the traffic of a UE is the use of UE routing selection policy (URSP) traffic descriptors. However, the types of URSP traffic descriptors have been limited in the 3GPP networks.

These additional URSP traffic descriptors may be utilized for routing of traffic of UEs within the 3GPP networks that can enhance and/or improve service provided to the UEs. The additional URSP traffic descriptors may be implemented by a 3GPP network system (such as a fifth generation (5G) network system in some embodiments) for routing of traffic of UEs connected to the network system.
UE Policy Enhancement—New Traffic Categories
3GPP release 18 (Rel-18) has approved a new Study Item on UE Policy Enhancement (SP-211649. (9-10 Dec. 2021). New SID: Study on enhancement of 5G UE Policy. TSG SA Rel-18 Prioritization Workshop).
Groupe Speciale Mobile Association (GSMA) has sent a liaison statement (LS) to SA2 (S2-2105356. (16-27 Aug. 2021). LS on Traffic Categories in URSP. SA WG2 Meeting #52-146E) in August 2021 wherein GSMA has profiled the use of user equipment routing selection policy (URSP) in their permanent reference document (PRD) NG.114 (NG.114. (7 Aug. 2020). IMS Profile for Voice, Video and Messaging over 5GS. GSM Association) and NG.113 (NG.113. (28 May 2021). 5GS Roaming Guidelines. GSM Association) based on use of URSP functionality in 3GPP technical specification (TS) 23.503 (TS 23.503. “3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Policy and charging control framework for the 5G System (5GS); Stage 2 (Release 17).” 3GPP Organization Partners, March 2022.) and TS 24.526 (TS 24.526. “3rd Generation Partnership Project; Technical Specification Group Core Network and Terminals; User Equipment (UE) policies for 5G System (5GS); Stage 3 (Release 17).” 3GPP Organization Partners, December 2021.). GSMA has concluded that standardized and mobile network operator (MNO) specific traffic categories need to supported in URSP traffic descriptors. Standardized traffic categories could be defined by 3GPP or by GSMA. MNO-specific traffic categories should be represented by a number of octets (flexible format to allow any string).
Examples of these traffic categories are Enterprise, Gaming, and Video Streaming. Enterprise may include traffic from one or more applications related to Enterprise service. Gaming may include traffic from one or more applications related to Gaming service, e.g., with low latency requirement. Video Streaming may include traffic from one or more applications related to Video Streaming, e.g., high-definition (HD) video streaming, 4K video streaming. A given traffic category can be used by more than one application simultaneously, and one application can simultaneously use more than one traffic category.
In the UE Policy Study Item objective #6 aims to investigate how to support standardized and operator specific traffic categories in the traffic descriptor of URSP. 3GPP has defined two major policy components for access in 5GC (WLAN): 1) UE route selection policy URSP which is a prioritized list of URSP rules provisioned by policy control function (PCF); and 2) Access Network discovery and selection policy (ANDSP) for non-3GPP access. The UE Route Selection Policy URSP may consist of Rule precedence, Traffic descriptors and Route Selection descriptors. The Access Network discovery and selection policy (ANDSP) for non-3GPP access may consist of wireless local area network (WLAN) Selection policy components for selection of WLAN and Non-3GPP access network (N3AN) node configuration information for selection of non-3GPP interworking function (N3IWF) or evolved packet data gateway (ePDG).
UE Policy Enhancement—Issue (SA2 TR 23.700-85 (TR 23.700-85. “3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Study on enhancement of 5G User Equipment (UE) policy (Release 18).” 3GPP Organization Partners, March 2022.))
3GPP SA2 has agreed the following issue: Support standardized and operator-specific traffic categories in URSP. SA2 will investigate how to support traffic categories in the traffic descriptor of URSP. Following aspects will be considered: 1) Definition of Traffic Category use cases and how to support both standardized traffic categories and MNO-specific traffic categories. If standardized values for traffic categories are defined, what are the various traffic categories that need to be standardized; 2) Whether the existing URSP design can be used to support the traffic category. If not, how to support traffic category in the traffic descriptor of a URSP rule; and 3) Traffic categories should support mechanisms that enable the UE to uniquely identify and categorize the traffic generated by any active application in a consistent manner across UE implementations.
General Concept—New Traffic Categories
Examples of these traffic categories based on application or specific service types are enterprise, gaming, and video streaming. Enterprise may include traffic from one or more applications related to Enterprise services. For example, the enterprise traffic category may include traffic of a UE related to applications for enterprise services, such for applications executed in an office setting, applications related to electronic mail (“email” or “e-mail”) file downloads, applications related to email, applications related to audio or video conferencing, applications related to browsing the internet, applications related to electronic messaging, or other applications that are defined or registered as being associated with enterprises. Gaming traffic category may include traffic from one or more applications related to Gaming service, for example, with low latency requirement. For example, the gaming traffic category may include traffic of a UE related to gaming applications, which may benefit from real-time traffic and/or low-latency traffic. Video Streaming traffic category may include traffic from one or more applications related to Video Streaming, for example, HD video streaming, 4K video streaming. For example, the video streaming traffic category may include traffic of a UE related to applications, and/or particular services of applications, related to video streaming, such as HD video streaming, 4K video streaming, and/or other video streaming.
Traffic in each category can be categorized by application/service type which can point to a range of values for a set of QoS related attributes. These QoS related attributes can be as follows: 1) Priority level (scheduling priority among flows); 2) Packet delay budget (latency); 3) Packet error rate (congestion and reliability); 4) Burst window (max throughput per unit time); and 5) Averaging window (guaranteed flow bit rate over unit time).
In addition to above traffic categories can also be: 1) MNO (Mobile Network Operator) specific; and 2) Best QoS (which can also be referred to as “optimal QoS request”). Best QoS can be expected in a slice. Best QoS can include traffic from an application that requires a specific QoS (specific parameters) but does not have exact mapping to a category included above.
Traffic descriptors can be defined either based on: 1) Service type of application (email, video, gaming etc.) which can point to a range of values for a set of QoS related attributes or 2) Traffic characteristics (just QoS attributes with no mapping to service/application types). Specific QoS attributes could have a relative priority level. As an example there could be relative priority among the QoS attributes (e.g. low latency, high bandwidth slice with latency as higher priority). Specific QoS attributes could have a range of values. Priority in a slice can be given to a single or multiple QS attributes (e.g. prioritize latency and packet error rate over bandwidth for something like voice traffic, gaming response traffic, etc.).

If the other values are received (for example, included in the structure in a communication), the other values may be interpreted as unknown.
UE Policy Enhancement—URSP Traffic Descriptors for New Traffic Categories
Additional traffic descriptors may be defined for use in the structure illustrated by the table 100 (
The table 300 illustrates the traffic descriptors 302 with corresponding values 304. In particular, the values 304 may be utilized in the traffic category descriptor element 128 to indicate the corresponding traffic descriptors 302. As shown in the illustrated in the table 300, the values 304 may be an eight bit value in some embodiments. A UE may determine a traffic descriptor of the traffic descriptors 302 for traffic based on an application associated with the traffic, a service type associated with the traffic, an MNO specification defined for the traffic, or some combination thereof. The UE may provide a communication with the value of the values 304 corresponding to the determined traffic descriptor to indicate routing for the traffic.
The traffic descriptors 302 may include a match-all type traffic descriptor 306 and/or an OS Id+OS App ID type traffic descriptor 308. The match-all type traffic descriptor 306 may be equivalent to the match-all type traffic descriptor 206 (
Some of the traffic descriptors 302 may by service type traffic descriptors in the table 300. For example, each of these traffic descriptors in the portion of the traffic descriptors 302 may correspond to an application and/or a service type of an application, where the traffic descriptor to be utilized for the routing may be determined based on the application and/or the service type of the application. These traffic descriptors 302 may be divided into enterprise traffic descriptors 314, gaming traffic descriptors 338, and video streaming traffic descriptors 358. The traffic descriptors 302 (or some portion thereof, such as the enterprise traffic descriptors 314, the gaming traffic descriptors 338, and the video streaming traffic descriptors 358) may be expressed in terms of one or more QoS attributes, such as a priority, a packet delay, an error rate, a burst volume, an averaging window, or some combination thereof.
The enterprise traffic descriptors 314 may be utilized for UE traffic related to enterprises, such as traffic from an office setting, traffic related to email (including email file downloads), traffic related to audio or video conferencing, traffic related to browsing the internet, traffic related to electronic messaging, and/or traffic for applications defined or registered as being associated with enterprises. In some embodiments, the enterprise traffic descriptors 314 may define a particular routing (which may be referred to as a pipe) for all traffic associated with an enterprise. For example, the enterprise traffic descriptors 314 may not differentiate between traffic based on traffic characteristics when routing the traffic, and may instead route all the traffic associated with the enterprise traffic descriptors 314 by a same routing. Accordingly, the enterprise traffic descriptors 314 may be a good fit for the type of traffic of the enterprise, which may be referred to as a best effort. The enterprise traffic descriptors 314 may include a voice traffic descriptor 316, an email traffic descriptor 318, a browser/chat traffic descriptor 320, and/or a conferencing traffic descriptor 322, as illustrated in the table 300. Each of the enterprise traffic descriptors 314 may have corresponding values used to indicate the enterprise traffic descriptors 314 and/or corresponding attributes for the enterprise traffic descriptors 314.
The voice traffic descriptor 316 may be utilized for applications related to voice communication (such as telephone communication and/or voice over internet protocol (VoIP)). For example, a UE may determine that an application being executed by the UE and/or a service being provided by the UE is related to voice communication. Based on the determination that the application and/or the service is related to voice communication, the UE may determine that the voice traffic descriptor 316 is to be utilized for indicating the routing of traffic for the application and/or the service.
The voice traffic descriptor 316 may have a corresponding third value 324 that can be utilized to indicate the voice traffic descriptor 316. The UE may provide the third value 324 in a communication that can indicate that the traffic associated with the communication is to be routed in accordance with the voice traffic descriptor 316. In the illustrated embodiment, the third value 324 is ‘11111001’, although it should be understood that the third value 324 may be different in other embodiments.
The voice traffic descriptor 316 may have corresponding attributes 326 for the traffic related to the voice traffic descriptor 316, where the routing of the traffic may be performed to achieve the attributes 326. For example, the attributes 326 may include a priority indication, a packet delay indication, a packet error rate indication, a burst volume indication, an averaging window indication, or some combination thereof. In the illustrated embodiments, the attributes 326 for the voice traffic descriptor 316 are shown as a priority value of 20, a packet delay value of 100 milliseconds (ms), a packet error rate value of 0.01, and an averaging window of 2000 ms. In this embodiment, the burst volume is not applicable. It should be understood in other embodiments, these attributes may be defined with different values. A network device (which may include a base station (such as a nodeB, an enhanced nodeB (eNB), or a next generation nodeB (gNB)), a core network, or some combination thereof) may route traffic associated with the voice traffic descriptor 316 to meet these attribute values.
The email traffic descriptor 318 may be utilized for applications related to email (including email file downloads). For example, a UE may determine that an application being executed by the UE and/or a service being provided by the UE is related to email. Based on the determination that the application and/or the service is related to email, the UE may determine that the email traffic descriptor 318 is to be utilized for indicating the routing of traffic for the application and/or the service.

The table 400 includes values that are defined for traffic descriptors. There are other values that may be undefined for traffic descriptors. All other values may be spare. If the other values are received, the other values may be interpreted as unknown. Example values of
Traffic categories can be defined based on type of service (e.g., enterprise class services, gaming services, video streaming services, etc.) handled by an application which can then map to a range of values for a set of QoS attributes that define these services adequately. As an example, voice traffic may have a 5G QoS identifier (5QI) value of 1, may use guaranteed bit rate (GBR) resources, have default priority level of 20, may have packet delay of 100 ms, packet error rate of 10-2 and averaging window of 2000 ms.
Another way to characterize traffic categories can be based on just the traffic characteristics and QoS attributes. The specific QoS attributes could have a relative priority level (e.g., low latency, high bandwidth slice with latency as higher priority). Priority can be given to single or multiple QoS attributes depending on traffic category.
It may be a little easier to define traffic categories based on traffic characteristics as a limited set of traffic characteristics could cover a large number of applications and services whereas it may be difficult to cover all services or application types. Defining traffic categories based on traffic characteristics also alleviates privacy concerns as for example, a “low priority, low bandwidth, normal/high latency data connection” may reveal much less information about user, than say for example “use of social media”. It may also be more meaningful to associate traffic characteristics to different flows than say service types. As an example, a gaming application may have multiple flows active at any given time but only a few of them may be carrying low latency traffic. A slice that is configured for handling “low latency” traffic for any gaming application could be much more useful in improving user experience as compared to when all active flows are mapped on to a “gaming” slice.
The 5G QoS characteristics describe the edge-to-edge packet treatment received by a QoS flow between the UE and UPF in terms of various performance characteristics. These performance characteristics include Resource type (GBR, non-GBR), Priority level, Packet delay budget, Packet error rate, Averaging window, Maximum data burst volume, etc. Standardized 5QI values are specified for services that are frequently used and the one-to-one mapping between standardized 5QI values and the 5G QoS performance characteristics.
Traffic categories can be defined based on type of service handled by an application. As an example, enterprise class applications could include traffic categories for email, browsing, chat, conferencing, voice, etc. Similarly gaming applications could include real-time gaming, interactive gaming and other games which could include extended reality (XR) type of traffic as well. Similarly, video streaming class of applications could also include live or buffered streaming, HD streaming, 4K streaming traffic, etc. For each of these service types, the traffic categories can then be mapped to specific 5G QoS performance characteristics. In addition to different well known services, traffic categories can also be MNO specific or even have specific QoS attributes or parameters that may not map to a well-known services.
The table 500 illustrates a plurality of traffic descriptors. The traffic descriptors may be grouped based on services to which the traffic descriptors relate. In the illustrated embodiment in the table 500, the traffic descriptors are illustrated divided into an enterprise class 502, a gaming class 504, and a video streaming class 506. The enterprise class 502 may relate to services provided by an enterprise. The gaming class 504 may relate to services associated with gaming. The video streaming class 506 may relate to services associated with video streaming.
Each of the traffic descriptors may correspond to a 5QI value 508. Further, each of the traffic descriptors may be defined by one or more QoS attributes, such as a resource type 510, a default priority level 512, a packet delay budget 514, a packet error rate 516, a default maximum data burst volume 518, and/or a default averaging window 520. For example, the enterprise class 502 may include a voice traffic descriptor 522. The voice traffic descriptor 522 may correspond to a 5QI value 508 of 1. Further, the voice traffic descriptor 522 may have specified QoS attributes of a resource type 510 of GBR, a default priority level 512 of 20, a packet delay budget 514 of 100 ms, a packet error rate 516 of 10−2, a default maximum data burst volume 518 that is not applicable (N/A), and a default averaging window of 2000 ms. 5 QI values and QoS attributes for the other traffic descriptors are indicated accordingly in the table 500.
The enterprise class 502 may include one or more traffic descriptors to be utilized for enterprise services. For example, the enterprise class 502 includes the voice traffic descriptor 522, an email, browser, chat traffic descriptor 524, and a conferencing traffic descriptor 526 in the illustrated embodiment. It is to be understood that the enterprise class 502 may include different traffic descriptors in other embodiments.
The gaming class 504 may include one or more traffic descriptors to be utilized for enterprise services. For example, the gaming class 504 includes a real time gaming traffic descriptor 528, an interactive gaming traffic descriptor 530, and an augmented reality traffic descriptor 532 in the illustrated embodiment. It is to be understood that the gaming class 504 may include different traffic descriptors in other embodiments.
The video streaming class 506 may include one or more traffic descriptors to be utilized for enterprise services. For example, the video streaming class 506 includes a live streaming traffic descriptor 534, a buffered streaming traffic descriptor 536, and an HD streaming traffic descriptor 538 in the illustrated embodiment. It is to be understood that the video streaming class 506 may include different traffic descriptors in other embodiments.
Traffic categories can also be defined directly based on traffic characteristics and the specific QoS attributes could have a relative priority level. As an example, for a certain class of traffic, there could be relative priority among the QoS attributes latency and bandwidth (e.g., low latency and high bandwidth with latency as higher priority). Priority can be given to single or multiple QoS attributes (e.g., prioritize latency and packet error rate over bandwidth for voice traffic, prioritize latency and bandwidth over packet error rate for gaming or video streaming traffic, etc.).
The table 600 illustrates traffic descriptors that may be defined based traffic characteristics. Further, the traffic descriptors may be defined based on a service type. For example, the traffic descriptors include a real-time online interaction traffic descriptor 602, a default bearer traffic descriptor 604, a video streaming traffic descriptor 606, an augmented reality (AR)/virtual reality (VR) traffic descriptor 608, a background traffic descriptor 610, an alternative background traffic descriptor 612, and an off peak data/cost traffic descriptors 614. Each traffic descriptor may be utilized for certain operations, as indicated in usage examples 616. It should be understood that different traffic descriptors defined on traffic characteristics may be defined in other embodiments.
Each of the traffic descriptors may be defined based on QoS attributes. For example, the traffic descriptors may be defined by latency 618, loss 620, bandwidth 622, and whether the traffic needs, or is defined to be, managed 624 (which will be referred to as “needs to be managed” for clarity). Values for each of the QoS attributes may be defined based on a defined degree. For example, the QoS attributes may be defined with values of low, normal, or high. For latency 618, low may refer to an amount of latency less than a first value, normal may refer to an amount of latency greater than or equal to the first value and less than a second value, and high may refer to an amount of latency greater than or equal to the second value. For loss 620, low may refer to an amount of data loss less than a first value, normal may refer to an amount of data loss greater than or equal to the first value and less than a second value, and high may refer to an amount of data loss greater than or equal to the second value. For bandwidth 622, low may refer to an amount of bandwidth less than a first value, normal may refer to an amount of bandwidth greater than or equal to the first value and less than a second value, and high may refer to an amount of bandwidth greater than or equal to the second value.
In the illustrated example of the traffic descriptors in table 600, the real-time online interaction traffic descriptor 602 is defined with a latency 618 of low, a loss 620 of normal, and a bandwidth 622 of low. The default bearer traffic descriptor 604 is defined with a latency 618 of normal, a loss 620 of normal, and a bandwidth 622 of normal. The video streaming traffic descriptor 606 is defined with a latency 618 of high, a loss 620 of low, and a bandwidth 622 of high. The AR/VR traffic descriptor 608 is defined with a latency 618 of high, a loss 620 of normal, and a bandwidth 622 of high. The background traffic descriptor 610 is defined with a latency 618 of high, a loss 620 of normal, and a bandwidth 622 of normal. The alternative background traffic descriptor 612 is defined with a latency 618 of high, a loss 620 of high, and a bandwidth 622 of normal.

The UE 702 may execute one or more programs and/or operations that produce traffic (for example, communications) between the user equipment and one or more other elements of the system. The UE 702 may determine a traffic descriptor from the traffic descriptors for the traffic. For example, the processors 706 may access the traffic descriptors from the memory 704 and determine one of the traffic descriptors to be utilized for the traffic. The traffic descriptor to be utilized for the traffic may be determined based on an application associated with the traffic, a service associated with the traffic, target attributes for transmission of the traffic, or some combination thereof in embodiments.

In embodiments where the traffic descriptors are provided to the UE 702 during registration of the UE 702, the core network 708 may detect a registration message received from the UE 702 or another indication of registration of the UE 702. In response to the registration message or other indication, the PCF 712 and/or the AMF 714 may generate a communication having traffic descriptors, where the communication may have the structure described in relation to table 100 in some embodiments. In some embodiments, the communication may be a non-access stratum (NAS) message.

In other instances, the core network 708 may provide traffic descriptors to the UE 702 after the UE 702 has been registered with the core network 708. The core network 708 may provide the traffic descriptors, or some portion thereof, at set intervals, in response to updates to the traffic descriptors, and/or in response to other triggers. The PCF 712 and/or the AMF 714 may generate a communication having traffic descriptors, where the communication may have the structure described in relation to table 100 in some embodiments. In some embodiments, the communication with the traffic descriptors may be a NAS message.

The UE 702 may determine a traffic descriptor to be utilized with the traffic to indicate the routing for the traffic. In embodiments, the UE 702 may determine the traffic descriptor to be utilized based on the application, the service being provided, target attributes for the traffic, or some combination. The UE 702 select the traffic descriptor for the traffic from the traffic descriptors stored in the memory 704. The UE 702 may generate a communication that indicates the traffic descriptor for the traffic, such as by including a corresponding value to the traffic descriptor. The UE 702 may transmit the communication at a start of, or prior to the start of, the traffic.
The core network 708 may detect the communication received from the UE 702 and identify the traffic descriptor from the communication. The core network 708 may determine a routing for associated traffic based on the traffic descriptor.

The components of the UE 1200 may be coupled with various other components over one or more interconnects 1232, which may represent any type of interface, input/output, bus (local, system, or expansion), transmission line, trace, optical connection, etc. that allows various circuit components (on common or different chips or chipsets) to interact with one another.
The processors 1204 may include processor circuitry such as, for example, baseband processor circuitry (BB) 1204A, central processor unit circuitry (CPU) 1204B, and graphics processor unit circuitry (GPU) 1204C. The processors 1204 may include any type of circuitry or processor circuitry that executes or otherwise operates computer-executable instructions, such as program code, software modules, or functional processes from memory/storage 1212 to cause the UE 1200 to perform operations as described herein.

In some embodiments, the PMIC 1224 may control, or otherwise be part of, various power saving mechanisms of the UE 1200. For example, if the platform UE is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the UE 1200 may power down for brief intervals of time and thus save power. If there is no data traffic activity for an extended period of time, then the UE 1200 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE 1200 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The UE 1200 may not receive data in this state; in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
A battery 1228 may power the UE 1200, although in some examples the UE 1200 may be mounted deployed in a fixed location, and may have a power supply coupled to an electrical grid. The battery 1228 may be a lithium ion battery, a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like.
