Description
FIELD OF TECHNOLOGY
The following relates to wireless communications, including configuring route selection policies.
Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal frequency division multiple access (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE) .
In some wireless communications system, a UE may have one or more applications that may each involve communications with a network. The UE may connect to the network in order to allow the application to communicate with the network, where the network connection is governed by a UE route selection policy (URSP) that is indicated to the UE by the network. Improved techniques for indicating URSPs associated with applications may be desirable.

In some wireless communication systems, a user equipment (UE) may communicate application data with a network according to a UE route selection policy (URSP) . That is, the URSP may govern access policies for communicating with the network for that application. Prior to a UE establishing a data connection associated with an application (e.g., for communicating application data with the network) , the UE may receive an indication of a URSP to use for that application from the network. In some cases, the network may indicate URSPs to each UE being served by the network (e.g., hundreds or thousands of UEs) and may indicate URSPs for each application at each UE (e.g., hundreds or thousands of applications at each UE) . Although the network may track and manage the URSPs for each application of each UE being served by the network, doing so may be impractical.
In the example of wireless communication systems as disclosed herein, the network may indicate URSPs to a UE in response to receiving a request for the URSP. That is, each UE may identify applications at the UE that are configured for data communications with the network in accordance with a URSP and may transmit requests to the network for URSPs associated with the identified applications. In response to a request for a URSP, the network may indicate a URSP associated with the application to the UE. The UE may then establish a data connection with the network in accordance with the indicated URSP.
Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are then described in the context of a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to configuring route selection policies.
FIG. 1 illustrates an example of a wireless communications system 100 that supports configuring route selection policies in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.
The base stations 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may be devices in different forms or having different capabilities. The base stations 105 and the UEs 115 may wirelessly communicate via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support the communication of signals according to one or more radio access technologies.
The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, the base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) , as shown in FIG. 1.
The base stations 105 may communicate with the core network 130, or with one another, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface) . The base stations 105 may communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 105) , or indirectly (e.g., via core network 130) , or both. In some examples, the backhaul links 120 may be or include one or more wireless links.
One or more of the base stations 105 described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or other suitable terminology.
A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the base stations 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
The UEs 115 and the base stations 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.
Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) . Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams) , and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.
The time intervals for the base stations 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T
s=1/ (Δf
max·N
f) seconds, where Δf
max may represent the maximum supported subcarrier spacing, and N
f may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N
f) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
Physical channels may be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
In some examples, a base station 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.
The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions) . Ultra-reliable communications may include private communication or group communication and may be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT) , mission critical video (MCVideo) , or mission critical data (MCData) . Support for mission critical functions may include prioritization of services, and mission critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency may be used interchangeably herein.
In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol) . One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1: M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a base station 105.
The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to the network operators IP services 150. The network operators IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service. The core network 130 may additionally include a point coordination function (PCF) that indicates, to each UE 115 being served by the core network 130, which URSP to use for routing traffic associated with an application at the UE 115.
Some of the network devices, such as a base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC) . Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs) . Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105) .
The wireless communications system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
The wireless communications system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA) . Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
A base station 105 or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 may be located in diverse geographic locations. A base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.
Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
In wireless communications system 100, a UE 115 may communicate application data with the core network 130 (e.g., via a base station 105) according to a URSP. Prior to a UE 115 establishing a data connection associated with an application (e.g., for communicating application data with the core network 130) , the UE 115 may receive an indication of a URSP to use for that application from the PCF of the core network 130. In some cases, the PCF may indicate URSPs to each UE 115 being served by the core network 130 (e.g., hundreds or thousands of UEs 115) and may indicate URSPs for each application at each UE 115 (e.g., hundreds or thousands of applications at each UE) . Although the PCF may track and manage the URSPs for each application of each UE 115 being served by the core network 130, doing so may be impractical. For example, it may be impractical for the PCF to track applications at a UE 115 that are installed, removed, or updated while the UE 115 is communicating with the core network 130 via one or more base stations 105.
In the example of wireless communications system 100, the PCF of the core network 130 may indicate URSPs to a UE 115 in response to receiving a request for the URSP. That is, each UE 115 may identify applications at the UE 115 that are configured for data communications with the core network 130 in accordance with a URSP and may transmit requests to the core network 130 for URSPs associated with the identified applications. In response to a request for a URSP, the core network 130 may indicate a URSP associated with the application to the UE 115. The UE 115 may then establish a data connection with the core network 130 in accordance with the indicated URSP.
FIG. 2 illustrates an example of a wireless communications system 200 that supports configuring route selection policies in accordance with aspects of the present disclosure. In some examples, the wireless communications system 200 may implement aspects of wireless communications system 100. The wireless communications system 200 may include a UE 115-a and a base station 105-a, which may be examples of a UE 115 and a base station 105, respectively, as described with reference to FIG. 1.
The UE 115-a may be in communication with the base station 105-a via the communication link 205. In some cases, the base station 105-a may provide a link to a network (e.g., a core network as described with reference to FIG. 1) to the UE 115-a. The UE 115-a may include one or more applications 225 that are configured to participate in data communications with the network via the base station 105-a in accordance with a URSP. For example, the application 225-a may be configured to participate in data communications with the network via the base station 105-a in accordance with a first URSP and the application 225-b may be configured to participate in data communications with the network via the base station 105-a in accordance with a second URSP.
The UE 115-a may perform a registration procedure (e.g., a network slicing registration procedure) with the base station 105-a. That is, the wireless communications system 200 may support one or multiple network slices over one or multiple radio access technologies. Each network slice may provide specific network capabilities and network characteristics. For example, a network slice may include dedicated or shared resources of a wireless communications system 200 in terms of processing power, storage, and bandwidth for a particular service or application. A network slice may also span across multiple network devices, for example, a base station 105-a, a network function of a core network, etc. A network function may be a logical node, which may be implemented in hardware, code (e.g., software or firmware) executed by a processor, or any combination thereof, to support network slices in the wireless communications system 200. During the registration procedure, the network may indicate, via the base station 105-a, one or more network slicing instances that the UE 115-a may utilize to communicate with the network (e.g., via single-network slice selection assistance information (S-NSSAI) ) .
Prior to establishing a data connection for an application 225 (e.g., via one of the network slicing instances that are useable or allowable by the UE 115-a) , the UE 115-a may determine which URSP to use for the application 225. The UE 115-a may transmit a URSP request 210 to the base station 105-a requesting an indication of which URSP to use for an application 225 at the UE 115-a. In some cases, the UE 115-a may transmit the URSP request 210 as part of the registration procedure. In some other cases, the UE 115-a may transmit the URSP request 210 as part of a UE 115-a configuration updating procedure (e.g., during which a configuration of the UE 115-a may be updated by the network via the base station 105-a) .
For example, the UE 115-a may transmit the URSP request 210 requesting an indication (e.g., from the network) of which URSP to use for the application 225-b. In some cases, the UE 115-a may transmit a single URSP request 210 requesting an indication of which URSPs to use for more than one application 225 (e.g., for two applications 225, for three applications 225, for four applications 225) . For example, the URSP request 210 may request an indication of which URSP to use for the application 225-a and the application 225-b.
The UE 115-a may include an application identifier in the URSP request 210 indicating which application 225 the URSP request 210 is associated with. For example, if the UE 115-a transmits the URSP request 210 for the application 225-a, the UE 115-a may include an application identifier associated with the application 225-a within the URSP request 210. Additionally, if the UE 115-a transmits the URSP request 210 requesting an indication of which URSP to use for the application 225-a and the application 225-b, the URSP request 210 may include application identifiers associated with both the application 225-a and the application 225-b. The UE 115-a may additionally include an indication of a precedence value (e.g., a rule precedence value) associated with each application and a traffic descriptor (e.g., indicating that the requested URSP is associated with application traffic) within the URSP request 210.
In response to the URSP indication 215, the network may transmit a URSP indication 215 to the UE 115-a via the base station 105-a. The URSP indication 215 may indicate a URSP that the UE 115-a is to use for each of the applications 225 indicated within the URSP request 210. For example, if the URSP request 210 indicated a request for a URSP associated with the application 225-a, the URSP indication 215 may indicate a URSP for the same application 225-a. If the URSP request 210 indicated more than one application 225, the URSP indication 215 may also indicate more than one URSP (e.g., for each of the more than one applications 225) . In some cases, the URSP indication 215 may include additional information associated with the indicated URSP. For example, the URSP indication 215 may include one or more of an indication of a route selection descriptor precedence, a network slicing instance, an indication of a session and service continuity, an indication of the data network name selection, and an access type preference.
The UE 115-a may store, at the UE 115-a, an indication of the URSP indicated by the URSP indication 215. For example, the UE 115-a may store the indication of the URSP within a cache at the UE 115-a. Thus, the UE 115-a may utilize the URSP to route data associated with the application 225 in the future without having to transmit an additional URSP request 210 any time the application 225-a communicates with the network via the base station 105-a. In some cases, the UE 115-a may be configured to periodically request an updated URSP for application 225 (e.g., even in a case that the UE 115-a has stored an indicated URSP associated with the application 225 at the UE 115-a) . For example, the UE 115-a may be configured to transmit a request for an update to the URSP associated with application 225-a according to a first periodicity.
After the UE 115-a receives the URSP indication 215 indicating a URSP associated with at least one of the applications 225 at the UE 115-a, the UE 115-a ay establish a data connection with the base station 105-a in accordance with the URSP. That is, the UE 115-a may establish a protocol data unit (PDU) session with the network (e.g., via the base station 105-a) for routing data between the network and the application 225. The UE 115-a may then route communications 220 associated with the application 225 between the base station 105-a and the application 225 in accordance with the URSP.
FIG. 3 illustrates an example of a process flow 300 that supports configuring route selection policies in accordance with aspects of the present disclosure. In some examples, process flow 300 may implement aspects of wireless communication systems 100 and 200. For example, the UE 115-b may be an example of the UEs 115 as described with respect to FIGs. 1 and 2. Additionally, the base station 105-b may be an example of the base stations 15 as described with respect to FIGs. 1 and 2.
At 305, the UE 115-b may identify that the UE 115-b includes an application which is configured to participate in data communications with a network (e.g., via the base station 105-b or another similar network node) in accordance with a route selection policy (e.g., a URSP) .
At 310, the UE 115-b may transmit, to the network via the base station 105-b, a request for the route selection policy (e.g., a URSP request) associated with the application. In some cases, the UE 115-b may transmit the URSP request as part of a registration procedure to obtain one or more network slicing instances on which the UE 115-b is allowed to communicate. In some other cases, the UE 115-b may transmit the URSP request as part of a UE 115-b configuration update procedure. Additionally or alternatively, the UE 115-b may transmit the URSP request in accordance with a periodicity for URSP requests.
At 315, the base station 105-b may transmit, in response to the request, an indication of the route selection policy (e.g., a URSP indication) associated with the application. For example, a PCF at the network may identify the route selection policy associated with the application and may transmit an indication of the identified route selection policy to the UE 115-b via the base station 105-b.
At 320, the UE 115-b may store the indication of the route selection policy associated with the application (e.g., at a cache of the UE 115-b) .
At 325, the UE 115-b may establish a data connection in accordance with the route selection policy. For example, the UE 115-b may establish a PDU session with the network via the base station 105-a in accordance with the URSP.
At 33, the UE 115-b may transmit, after establishing the data connection at 325, a request for an update to the route selection policy associated with the application in accordance with the periodicity. In some cases, the periodicity may be associated with the application (e.g., defined for the application) . Additionally or alternatively, the periodicity may be based on the URSP associated with the application, based on the network slicing instance associated with the established data connection, or a combination thereof.
