DETAILED DESCRIPTION

A wireless communications system may include communication devices that may support various access technologies (also referred to as a type of access). Examples of a type of access may include cellular access (e.g., 3GPP access, LTE, LTE-A, LTE-A Pro, or NR), non-cellular access (e.g., non-3GPP access, Wi-Fi, wireline), or a combination thereof. A communication device may support various access combinations for a session. For example, a communication device may use one type of access for wireless communications (e.g., to receive data traffic, transmit data traffic, or a combination thereof), or two types of accesses simultaneously for the wireless communication. The communication device may support ATSSS functionalities (e.g., dual networking functionalities) to distribute the wireless communication (e.g., data traffic) over the two types of accesses for the session (e.g., a multiple access PDU session). Accordingly, a UE may operate in accordance with an ATSSS mode in which uplink and/or downlink traffic of a UE may be served by a cellular network, a non-cellular network (e.g., WiFi), or both (via splitting). Methods for determining the ATSSS mode may be prompted based on a network becoming unavailable. For example, if the UE is receiving traffic split between a WiFi network and a cellular network, and then the UE leaves the coverage area of the WiFi network, the UE would then switch to have the traffic fully serviced by the cellular network. Waiting, however, until a network becomes unavailable to manage the ATSSS mode may introduce latency and decrease reliability for the UE.

To improve ATSSS operation, a UE may be configured to perform techniques for predicting network availability of a cellular network, a non-cellular network, or both, and pre-emptively taking action so as to reduce latency and improve reliability for the UE. For example, a UE may monitor one or more parameters of the cellular network, such as throughput, degree of quality of service (QoS) satisfaction, channel quality, channel occupancy, etc. The UE may also monitor one or more parameters of the non-cellular network such as receive signal-to-interference-plus-noise ratio (SINR) measurements, etc. and in some cases may monitor one or more parameters of the UE such as the motion of the UE, positioning of the UE, whether the UE is connected to Bluetooth, etc. The UE may input the one or more parameters of the cellular network, the non-cellular network, the UE, or a combination thereof into an algorithm (e.g., a neural network) and the algorithm may predict availability of the networks. If the algorithm predicts that one of the networks may become unavailable (e.g., in the future), the UE may be configured to signal to one or both of the networks that the network is unavailable prior to the network actually becoming unavailable, which may prompt one or both of the networks to adjust the ATSSS mode (e.g., ATSSS steering mode) of the UE accordingly. In some cases, the UE may autonomously adjust the ATSSS mode of the UE based on the prediction.

Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in coordinating communications across multiple networks in accordance with ATSSS modes by improving reliability, and decreasing latency, among other advantages. As such, supported techniques may include improved network operations and, in some examples, may promote network efficiencies, among other benefits.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects are then described with reference to a dual networking configuration and 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 techniques for operating in accordance with a dual networking mode for steering, switching and splitting traffic.

FIG.1illustrates an example of a wireless communications system100that supports techniques for operating in accordance with a dual networking mode for steering, switching and splitting traffic in accordance with aspects of the present disclosure. The wireless communications system100may include one or more base stations105, one or more UEs115, and a core network130. In some examples, the wireless communications system100may 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 system100may support enhanced broadband communications, ultra-reliable communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

The base stations105may be dispersed throughout a geographic area to form the wireless communications system100and may be devices in different forms or having different capabilities. The base stations105and the UEs115may wirelessly communicate via one or more communication links125. Each base station105may provide a coverage area110over which the UEs115and the base station105may establish one or more communication links125. The coverage area110may be an example of a geographic area over which a base station105and a UE115may support the communication of signals according to one or more radio access technologies.

The UEs115may be dispersed throughout a coverage area110of the wireless communications system100, and each UE115may be stationary, or mobile, or both at different times. The UEs115may be devices in different forms or having different capabilities. Some example UEs115are illustrated inFIG.1. The UEs115described herein may be able to communicate with various types of devices, such as other UEs115, the base stations105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown inFIG.1.

In some examples, one or more components of the wireless communications system100may operate as or be referred to as a network node. As used herein, a network node may refer to any UE115, base station105, entity of a core network130, apparatus, device, or computing system configured to perform any techniques described herein. For example, a network node may be a UE115. As another example, a network node may be a base station105. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE115, the second network node may be a base station105, and the third network node may be a UE115. In another aspect of this example, the first network node may be a UE115, the second network node may be a base station105, and the third network node may be a base station105. In yet other aspects of this example, the first, second, and third network nodes may be different. Similarly, reference to a UE115, a base station105, an apparatus, a device, or a computing system may include disclosure of the UE115, base station105, apparatus, device, or computing system being a network node. For example, disclosure that a UE115is configured to receive information from a base station105also discloses that a first network node is configured to receive information from a second network node. In this example, consistent with this disclosure, the first network node may refer to a first UE115, a first base station105, a first apparatus, a first device, or a first computing system configured to receive the information; and the second network node may refer to a second UE115, a second base station105, a second apparatus, a second device, or a second computing system.

The base stations105may communicate with the core network130, or with one another, or both. For example, the base stations105may interface with the core network130through one or more backhaul links120(e.g., via an S1, N2, N3, or other interface). The base stations105may communicate with one another over the backhaul links120(e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations105), or indirectly (e.g., via core network130), or both. In some examples, the backhaul links120may be or include one or more wireless links.

One or more of the base stations105described 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 UE115may 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 UE115may 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 UE115may 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 UEs115described herein may be able to communicate with various types of devices, such as other UEs115that may sometimes act as relays as well as the base stations105and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown inFIG.1.

The UEs115and the base stations105may wirelessly communicate with one another via one or more communication links125over 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 links125. For example, a carrier used for a communication link125may 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 system100may support communication with a UE115using carrier aggregation or multi-carrier operation. A UE115may 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 UE115receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE115. 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 UE115.

One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE115may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE115may be restricted to one or more active BWPs.

The time intervals for the base stations105or the UEs115may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1/(Δfmax·Nf) seconds, where Δfmaxmay represent the maximum supported subcarrier spacing, and Nfmay 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 systems100, 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., Nf) 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 system100and 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 system100may 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 UEs115. For example, one or more of the UEs115may 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 UEs115and UE-specific search space sets for sending control information to a specific UE115.

In some examples, a base station105may be movable and therefore provide communication coverage for a moving geographic coverage area110. In some examples, different geographic coverage areas110associated with different technologies may overlap, but the different geographic coverage areas110may be supported by the same base station105. In other examples, the overlapping geographic coverage areas110associated with different technologies may be supported by different base stations105. The wireless communications system100may include, for example, a heterogeneous network in which different types of the base stations105provide coverage for various geographic coverage areas110using the same or different radio access technologies.

The wireless communications system100may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system100may be configured to support ultra-reliable low-latency communications (URLLC). The UEs115may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

In some examples, a UE115may also be able to communicate directly with other UEs115over a device-to-device (D2D) communication link135(e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs115utilizing D2D communications may be within the geographic coverage area110of a base station105. Other UEs115in such a group may be outside the geographic coverage area110of a base station105or be otherwise unable to receive transmissions from a base station105. In some examples, groups of the UEs115communicating via D2D communications may utilize a one-to-many (1:M) system in which each UE115transmits to every other UE115in the group. In some examples, a base station105facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs115without the involvement of a base station105.

The core network130may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network130may 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 UEs115served by the base stations105associated with the core network130. 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 IP services150for one or more network operators. The IP services150may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.

Some of the network devices, such as a base station105, may include subcomponents such as an access network entity140, which may be an example of an access node controller (ANC). Each access network entity140may communicate with the UEs115through one or more other access network transmission entities145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs). Each access network transmission entity145may include one or more antenna panels. In some configurations, various functions of each access network entity140or base station105may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station105).

The wireless communications system100may 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 UEs115located 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 system100may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system100may 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 stations105and the UEs115may 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 station105or a UE115may 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 station105or a UE115may 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 station105may be located in diverse geographic locations. A base station105may have an antenna array with a number of rows and columns of antenna ports that the base station105may use to support beamforming of communications with a UE115. Likewise, a UE115may 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 station105, a UE115) 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 some wireless communications systems, such as wireless communications system100, a UE115may be configured to support improved methods of utilizing dual networking modes (e.g., ATSSS modes) to coordinate communications from multiple networks (e.g., accesses), such as one or more cellular networks, and one or more non-cellular networks (e.g., a WiFi network). The described techniques may allow a UE115to monitor an availability of one or more of networks the UE115is receiving service from. The UE115may predict an availability status of one or more of the networks and the UE115may adjust dual networking modes based on the availability. Accordingly, the UE115may predict that one or more of the networks will become unavailable and adjust modes prior to the unavailability so that communications are unaffected. For example, a UE115may monitor one or more first conditions pertaining to non-cellular communications between the UE115and a non-cellular network while the UE115is operating in a dual networking mode (e.g., an ATSSS mode) between the non-cellular network and a cellular network. The UE115may predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. In some cases, the UE115may determine whether to change dual networking modes bases on the availability status and may communicate in accordance with the same or a different dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction.

FIG.2illustrates an example of a wireless communications system200that supports techniques for operating in accordance with a dual networking mode for steering, switching and splitting traffic in accordance with aspects of the present disclosure. The wireless communications system200may include base station105-a, access node205, and UE115-a, which may be examples of a base station105, an access node, and UE115as described with reference toFIG.1. Base station105-amay serve a geographic coverage area110-a, and access node205may serve geographic coverage area110-b, where geographic coverage areas110-aand110-bmay partially overlap, or completely overlap. In some cases, UE115-amay implement a network availability monitoring procedure while operating in accordance with a dual network mode (e.g., an ATSSS mode). Additionally or alternatively, other wireless devices, such as base station105-a, access node205, or some combination of these devices, may implement a same or similar procedure for monitoring network availability.

Wireless communications system200may include communication devices (e.g., base stations105, access nodes205, UEs115) that may support various access technologies (also referred to as a type of access). Examples of a type of access may include cellular access (e.g., 3GPP access, LTE, LTE-A, LTE-A Pro, NR), non-cellular access (e.g., non-3GPP access, Wi-Fi, wireline), or a combination thereof. A communication device may support various access combinations for a session. For example, a communication device may use one type of access for wireless communications (e.g., to receive data traffic, transmit data traffic, or a combination thereof), or two types of accesses simultaneously for the wireless communications. The communication device may support ATSSS functionalities (e.g., dual networking functionalities) to distribute the wireless communication (e.g., data traffic) over the two types of accesses for the session (e.g., a multiple access PDU session).

For example, UE115-amay operate in accordance with an ATSSS mode in which uplink and/or downlink traffic of UE115-amay be served by a cellular network (e.g., base station105-a), a non-cellular network (e.g., WiFi, network, access node205), or both (via splitting). Accordingly, UE115-amay achieve high throughput by simultaneously being served by base station105-a, and access point205in accordance with an ATSSS mode. One example of a scenario in which UE115-amay utilize an ATSSS mode may include UE115-ain an environment in which the UE115has access to WiFi (e.g., a home, an office, a library). For example, with reference toFIG.2, base station105-amay be associated with a cellular network and access node205may be associated with a WiFi network, and UE115-amay be connected with both base station105-aand access node205.

In some cases, methods for determining an ATSSS mode may be prompted based on a network becoming unavailable. For example, if UE115-ais receiving traffic split between base station105-aand access node205, and then UE115-aleaves geographic coverage area110-bof access node205, UE115-amay then switch to have the traffic fully serviced by base station105-a. Waiting, however, until a network becomes unavailable to manage the ATSSS mode may introduce latency and decrease reliability for UE115-a.

To improve ATSSS operation, UE115-amay be configured to perform techniques for predicting network availability of a cellular network, a non-cellular network, or both, and may pre-emptively take action so as to reduce latency and improve reliability for UE115-a. Accordingly, UE115-amay be configured to monitor one or more first parameters associated with access node205, one or more second parameters associated with base station105-a, one or more third parameters associated with UE115-a, or a combination thereof. UE115-amay be configured to anticipate whether one or more of the networks is likely to become unavailable based on the monitored parameters. In the case that UE115-apredicts that one or more of the networks is likely to become unavailable, UE115-a, base station105-a, access node205, or a combination thereof may prompt UE115-ato change ATSSS modes prior to the unavailability so as to maintain reliable, reduce latency, and mitigate potential impacts on throughput.

The one or more first parameters may include receive signal-to-interference-plus-noise ratio (SINR) measurements, receive power measurements, signal variation, mobility detection of UE115-a, RF signatures, etc. For example, the receiver SINR measurements, the receive power measurements, or both may be based on channel occupancy measurements which may indicate cell loading. In another example, with reference to signal variation, UE115-aand/or a receiver if UE115-a(e.g., a WiFi receiver) may determine whether a receive signal is varying (e.g., at a WiFi receiver of UE115-a). In another example, with reference to RF signatures, UE115-amay determine whether there is a non-cellular RF signature (e.g., WiFi signal RF signature) to compare a non-cellular signal to. If so, UE115-amay determine whether current measurements indicate that the UE is moving out of WiFi coverage. An RF signature may include signal information from the serving access points (e.g., access node205), other detected access points, or a combination thereof.

The one or more second parameters may be based on whether UE115-ais transmitting and/or receiving on-going communications (e.g., traffic) via base station105-a. In some cases, if UE115-ais transmitting and/or receiving on-going traffic, then the second set of parameters may include throughput, a degree of quality of service (QoS) satisfaction, or both. If UE115-ais not transmitting and/or receiving on-going traffic with base station105-a, then the second set of parameters may include channel quality, channel occupancy, interference measurements, handover procedure, etc. For example, with reference to channel quality, UE115-amay receive one or more of synchronization signals, physical broadcast channel messages, or a combination therefore and perform one or more measurements on the one or more received signals, where the one or more measurements may indicate or otherwise be associated with a channel quality. In another example, with reference to channel occupancy (e.g., PDCCH occupancy), UE115-amay perform power detection which may indicate cell loading. UE115-amay determine an occupancy level of the channel based on the cell loading, power detection, or both. In another example, with reference to handover, UE115-amay determine whether UE115-ahas performed a handover procedure to a private cellular network (e.g., a home cellular network, an office cellular network), or a public cellular network. A private cellular network may provide coverage to a limited area, such as a home, or an office and accordingly may allow UE115-ato predict availability of the cellular network, such as in relation to movement of UE115-a.

The one or more third parameters may include motion of UE115-a, positioning of UE115-a, whether UE115-ais connected to Bluetooth, an application being used by UE115-a, QoS, etc. For example, UE115-amay determine whether UE115-ais moving (e.g., via GPS, one or more sensors such as accelerometers, motion sensors, etc.). UE115-amay determine a velocity of the movement, a direction of the movement, etc. If the UE115-ais moving, in some cases, UE115-amay determine a cause of the motion, such as whether the motion is due to an application (e.g., gaming, such as extended reality gaming). For example, UE115-amay determine whether the motion is typical of the motion perceived while gaming, thereby indicating that the UE115is likely not moving in a way that will impact network availability. Gaming movement, among other movement types, may not indicate that a UE115-ais leaving a coverage area, and in some cases may not be detected by localized movement. In some cases, UE115-amay determine whether the motion is due to the UE115moving around within a house, office, etc., due to the UE115leaving the house, the office, etc. Moving around a house, for example, may not indicate that network will become unavailable, whereas motion indicative that UE115-ais leaving the house may indicate that a network, such as the non-cellular network may become unavailable.

In another example, UE115-amay determine a position of UE115, such as via GNSS positioning (e.g., via a GNSS sensor). UE115-amay determine the position of UE115-ain relation to base station105-a, access node205, or both. For example, UE115-amay determine whether UE115-ais near a cell edge (e.g., edge of geographic coverage area110-a, edge of geographic coverage area110-b, or both). Nearing or moving around a cell-edge may be indicative that the network associated with the cell-edge that UE115-ais near may become unavailable.

In another example, UE115-amay determine whether UE115-ais connected to one or more other devices via Bluetooth. If so, UE115-amay determine whether the one or more other devices are associated with moving outside of a coverage area. For example, if UE115-adetermines that UE115-ais connected via Bluetooth with a gaming headset, UE115-amay determine that UE115-ais likely staying within a coverage area. In another example, if UE115-adetermines that UE115-ais connected via Bluetooth with a vehicle, UE115-amay determine that UE115-ais likely in a vehicle and is likely to move outside of a coverage area, such as a coverage area of a non-cellular network (e.g., the coverage area of a home WiFi network).

In another example, UE115-amay identify applications (e.g., operating systems) being run on UE115-a. For example, UE115-amay determine whether the applications are typically associated with remaining in the coverage area of a network, or are typically indicative that UE115-ais leaving a coverage area. For example, UE115-amay identify that UE115-ais running a gaming application, and therefore may determine that UE115-ais likely remaining in the one or more coverage areas (e.g., geographic coverage areas110-a,110-b). In another example, UE115-amay identify that a map application is running which may be indicative that a UE115-ais leaving one or more of geographic coverage areas110-a, and110-b.

In another example, UE115-amay identify a QoS requirement of communications that UE115-ais transmitting and/or receiving. UE115-amay determine a level of importance of maintaining multiple network links (e.g., communications links210-a,210-b, and210-cwith base station105-a, and access node205). For example, UE115-amay determine that to achieve the QoS requirement, UE115-aneeds the multiple links.

In some cases, the one or more third parameters may be a subset of the one or more first parameters such that the parameters associated with the non-cellular network in combination with the parameters associated with UE115-amay be used to predict availability of the non-cellular network. Similarly, the one or more third parameters may be a subset of the one or more second parameters such that the parameters associated with the cellular network in combination with the parameters associated with UE115-amay be used to predict availability of the cellular network. In some cases, the one or more first parameters, the one or more second parameters, the one or more third parameters, or a combination thereof may be determined by UE115-a, base station105-a, access node205, or a combination thereof.

Upon monitoring the one or more first parameters, the one or more second parameters, the one or more third parameters, or a combination thereof, UE115-amay be configured to input the first, second, and/or third set of parameters into one or more algorithms (e.g., neural networks, AI modules, machine-learning modules, a decision engine, a decision synthesizer, an adjustment synthesizer), where the one or more algorithms may predict network availability of base station105-a, access point205, or both. The one or more algorithms may receive inputs from various heterogenous sources, such as a non-cellular receiver (e.g., a WiFi receiver) of UE115-a, motion sensors, GNSS receivers, Bluetooth modules, OS modules, etc. In some cases, one algorithm may be associated with one set of parameters. For example, UE115-amay be configured with a first algorithm for predicting availability of access node205by inputting the first set of parameters and/or the third set of parameters. Accordingly, the first algorithm may predict the availably of access node205based on the parameters associated with access node205and/or based on the behavior of UE115-awith respect to access node205. Similarly, UE115-amay be configured with a second algorithm for predicting availability of base station105-aby imputing the second set of parameters, and/or the third set of parameters. Accordingly, the second algorithm may predict the availability of base station105-abased on the parameters associated with base station105-aand/or based on the behavior of UE115-awith respect to base station105-a. In some cases, for channel quality prediction, both a filter-based model (e.g., traditional filter-based mode) and neural network based model may be be used and subject to a selector based on prediction performance.

In some cases, an impact associated with each input may be soft-combined before being input to the algorithm, or while in the algorithm, For example, a WiFi channel quality measurement may be adjusted and in some cases may subject the adjusted WiFi channel quality measurement to a threshold. The adjusted WiFi channel quality may account for loading. In some cases, one or more backoff factors may be added to alerts from sources other than a non-cellular receiver (e.g., the WiFi receiver).

In some implementations, the one or more algorithms may be trained. For example, the one or more algorithms may be trained offline in which patterns and/or behaviors were identified based on other UEs115(e.g., generic patterns), studies, other offline methods, and then used to identify an outcome of UE115-abased on a pattern of UE115-a(e.g., a mobility pattern) matching one or more of the generic patterns. In such cases, the generic patterns may be pre-uploaded to a device. In some cases, the one or more algorithms may be trained via online training in which patterns and/or behaviors (e.g., of UE115-a, or other UEs115) are determined to change overtime and thus are being updated periodically, continuously, etc. In some cases, online training may be used for long-term model parameter adjustments (e.g., developing and/or adjusting an RF signature database), such as if the online training is complex. In some implementations, UE115-amay communicate with base station105-a, access node205, or both for the purpose of updating the one or more algorithms. Signaling with base station105-aand/or access point205may include a range of models used for this purpose, where the signaling may also be introduced for improving CSI feedback in general. Patterns may refer to an RF signature, motion characteristics, situations in the past that resulted in a change in network availability, etc.

In some cases, UE115-a, motion sensors of UE115-a, the one or more algorithms, or a combination thereof may identify whether UE115-ais moving, and identify a cause of identified motion. For example, the motion sensors may determine whether a motion of UE115-ais indicative that UE115-ais likely to move out of coverage of one or more networks. The motion sensors may determine whether motion is detected. If motion is not detected, then the motion sensors may determine that no adjustment is needed for network availability. For example, the motion sensors may determine that UE115-ais likely not moving out of a WiFi network, and therefore, the motion sensors may not adjust the available of the WiFi network from available to unavailable. If, however, motion is detected, then the motion sensors may determine if motion is due to gaming (e.g., due to Bluetooth connection, applications running on UE115-a, motion patters). For example, the motion sensors may compare the detected motion with one or more patterns (e.g., trained patterns, stored patterns, learned patterns) associated with gaming. If the motion is due to gaming, the one or more algorithms may determine that no adjustment is needed for network availability, as UE115-ais likely not moving in a way that impacts network coverage of UE115-a. If, however, motion is not due to gaming, the motion sensors may determine that the motion likely will impact network availability of one or more networks, or may perform one or more other decisions to further determine a cause of the motion.

If the motion sensors determine that the motion of UE115-awill likely impact network availability of the non-cellular network, the cellular network, or both, then the motion sensors may alert an adjustment module (e.g., an adjustment synthesizer, a decision synthesizer, a WiFi adjustment synthesizer, a cellular network adjustment synthesizer). The adjustment module may then determine whether to adjust the availability of one or more networks based on one or more inputs. For example, if a WiFi adjustment synthesizer receives an input that UE115-ais moving and that the motion is not due to gaming, the WiFi adjustment synthesizer may adjust the availability of the WiFi network to unavailable as UE115-amay be moving outside of a coverage area of the WiFi network (e.g., outside of geographic coverage area110-bof access node205). In some cases, mobility of UE115-amay be more likely to impact the availability of the non-cellular network than the cellular network because UE115-amay be unable to handover to another non-cellular network (e.g., another WiFi network) if the first one becomes unavailable. For example, the UE115may move out of range of a home WiFi network, and may be unable to connect to another WiFi network seamlessly because there may not be any public WiFi networks nearby and/or other nearby WiFi networks may be private. In another example, UE115-amay be moving from the coverage of one access point to another access point, where both access points are within a network (e.g., an enterprise network) but the mobility procedure may take time and may result in service outage. However, if a UE115-amoves out of range of a cellular network, the UE115may be more likely to perform a handover procedure with another cellular network. In some implementations, the one or more algorithms, the one or more adjustment modules, the motion sensors, or a combination thereof may perform mobility predication of UE115-abased on one or more inputs, such as inputs from a non-cellular receiver (e.g., a WiFi receiver), motion sensors, GNSS receivers, Bluetooth modules, OS modules, etc., where the inputs may include the one or more first, second, and/or third parameters,

The one or more algorithms may output a prediction of network availability. For example, if one or more parameters, such as UE mobility, are considered likely to cause UE115-ato fail to receive service from a network, the one or more algorithms may change the status of the impacted network. For example, if UE115-ais likely to move out of geographic coverage area110-b, the one or more algorithms may change the status of the network associated with access node205to unavailable. In some implementations, the one or more algorithms may output whether a mobility of UE115-awill likely result in UE115-amoving out of a coverage area110of a network, whether network availability will be impacted based on one or more other parameters, or a combination thereof. In some cases, the one or more algorithms may determine whether the availability status of one or more networks will likely change in a certain time period, such as in the next N number of seconds. The one or more algorithms may determine whether it is time to report, or determine a time to report that a network is unavailable based on the prediction that the network will become unavailable.

The one or more algorithms may determine whether to change ATSSS steering modes based on predicted availability. For example, the one or more algorithms may determine whether to adjust priorities assigned to the one or more networks. For example, if the UE115-ais determined to be at home (e.g., firmly within the bounds of a coverage area110of a non-cellular network), then the non-cellular network may be given a higher priority over the cellular network. However, if the one or more algorithms predicts a change in availability of the non-cellular network, such as predicting that UE115-ais likely moving out of coverage of the non-cellular network, then the ATSSS mode may assign the cellular network with the higher priority. In another example, if the UE115-ais determined to be at home (e.g., firmly within the bounds of a coverage area110of a non-cellular network), then the non-cellular network may be assigned active-standby. However, if the one or more algorithms predicts a change in availability of the non-cellular network, such as predicting that UE115-ais likely moving out of coverage of the non-cellular network, then the ATSSS mode may assign the cellular network with a higher priority, shortest delay, load-balancing, etc.

If one or more of the algorithms predicts that one of the networks may become unavailable (e.g., in the future), UE115-amay be configured to signal to one or both of base station105-aand access node205, an indication of the unavailable network, prior to the network actually becoming unavailable. In some cases, the signal may indicate that the network is currently unavailable, even if it is not. In some implementations, UE115-amay determine (or be configured) to transmit the signal to both access node205and base station105-a, regardless of which network is predicted to become unavailable. In some implementations, UE115-amay determine (or be configured) to transmit the signal to the network that is predicted to become unavailable. For example, if UE115-apredicts that access node205will become unavailable, then UE115-amay transmit the signal to access node205. In some cases, upon receiving the signal, access node205may relay a same or similar message to the one or more other networks involved in providing service to UE115-a(e.g., base station105-a). In some implementations, UE115-amay determine (or be configured) to transmit the signal to the network that is predicted to remain available. For example, if UE115-apredicts that access node205will become unavailable, then UE115-amay transmit the signal to base station105-a. In some cases, upon receiving the signal, base station105-amay relay a same or similar message to the one or more other networks involved in providing service to UE115-a, such as the network that is predicted to become unavailable (e.g., access node205). In some cases, the one or more networks that received the signal may transmit an acknowledgement message back to UE115-a

In some cases, UE115-amay indicate a time at which one or more of the networks is expected to become unavailable, a duration of time the one or more networks is expected to become unavailable. In some implementations, the signal may indicate additional feedback associated with one or more of the networks. For example, the signal may include an indication of abrupt changes (e.g., a UE115in a car, abrupt WiFi signal loss, etc.), a failure event report, a mobility report (e.g., utilizing positioning measurement report).

In some cases, the signal may indicate the network will likely become unavailable, which may prompt one or both of the networks (e.g., access node205, base station105-a) to adjust the ATSSS mode (e.g., ATSSS steering mode) of UE115-aaccordingly. In such cases, one or both of the networks may determine to change ATSSS modes for serving UE115-aand indicate the new ATSSS mode to UE115-a. In some cases, UE115-amay autonomously adjust the ATSSS mode of UE115-a. For example, UE115-amay autonomously adjust the traffic steering, switching, and/or splitting on the uplink, or adjust the feedback of the downlink channel quality feedback of a cellular and/or non-cellular system. In some cases, UE115-amay signal the new ATSSS mode to one or more both of the networks. Accordingly, if UE115-a, access node205, base station105-a, or a combination thereof predict that access node205will be unavailable to serve UE115-a(e.g., in the future, such as in a number of seconds, minutes, etc.), UE115-amay change an ATSSS mode to receive communications solely or primarily from base station105-ato maintain communication reliability and low latency.

FIG.3illustrates an example of a dual networking configuration300that supports techniques for operating in accordance with a dual networking mode for steering, switching and splitting traffic in accordance with aspects of the present disclosure. The dual networking configuration300may be implemented by a UE, a base station, an access node, or a combination thereof, which may be examples of the corresponding devices as described with reference toFIGS.1and2. In some cases, a UE may implement a network availability monitoring procedure while operating in accordance with a dual network configuration300(e.g., an ATSSS configuration). Additionally or alternatively, other wireless devices, such as a base station, an access node, or some combination of these devices, may implement a same or similar procedure for monitoring network availability.

ATSSS may enable simultaneous cellular and non-cellular (e.g., WiFi) connections at a device, such as a UE, which may offer both upper layer and lower layer control mechanisms. In accordance with ATSSS, Access Traffic Steering may refer to selection of an access network (AN) (e.g., a cellular access network, such as a 3GPP access network, and a non-cellular access, such as a non-3GPP access network) for a new data flow (e.g., IP flows) and transferring the traffic of this data flow over the selected AN. Access Traffic Switching may refer to moving all traffic of an ongoing data flow from one AN to another AN in a way that maintains the continuity of the data flow. Access Traffic Splitting may refer to splitting the traffic of a data flow across multiple ANs. An MA-PDU Session may be established between a UE and network for ATSSS which can exchange PDUs between the UE and the network by simultaneous use of cellular and non-cellular accesses. Uplink traffic over MA-PDU session

With reference to communicating uplink traffic, and when uplink resources are available for multiple network accesses, a UE may apply ATSSS rules and consider local conditions (e.g., such as network interface availability, signal loss, user preferences) to determine how to distribute the uplink traffic. With reference to communicating downlink traffic over a MA-PDU session, the UE may provide access availability and/or unavailability reports to the network, such as if requested (e.g., required) by the network (e.g., in the Measurement Assistance Information). In some cases, the ATSSS rules may refer to rules associated with ATSSS modes, such as steering modes (e.g., ATSSS steering modes, AT steering modes). For example, a steering mode may indicate how traffic is to be distributed across multiple accesses. A steering mode may set to active-standby that may include steering a SDF on a first access when the first access is available, and include switching the SDF to a second access when Active access becomes unavailable. Additionally or alternatively, a steering mode may be set to smallest delay that may include steering the SDF to the access that may result in the smallest delay. Additionally or alternatively, a steering mode may be set to load-balancing that may include steering the SDF to accesses so as to balance the load across the access. Additionally or alternatively, a steering mode may be set to priority-based which may include steering all the traffic of an SDF to the access network associated with the higher priority access until the higher priority network becomes congested, for example.

Accordingly, based on an ATSSS mode, a data flow may be split into two flows, each served by a network access. In some cases, the IP flow (e.g., IP 3) may be split in the lower layer by ATSSS-LL functionality310. In some other cases, an IP flow may be split in a higher layer by MPTCP functionality305, where the spit may result in multiple IP subflows (e.g., a subflow bound to IP 1, and a subflow bound to IP 2).

FIG.4illustrates an example of a process flow400that supports techniques for operating in accordance with a dual networking mode for steering, switching and splitting traffic in accordance with aspects of the present disclosure. The process flow400may illustrate an ATSSS communication scheme. For example, UE115-bmay perform a network availability monitoring procedure while operating in accordance with an ATSSS mode. Base station105-band UE115-bmay be examples of the corresponding wireless devices described with reference toFIGS.1through3. In some cases, base station105-bmay be cellular access network. In some cases, instead of UE115-bimplementing the network availability monitoring procedure, a different type of wireless device (e.g., a base station105, an access node) may perform a same or similar procedure. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

At405, UE115-bmay monitor one or more first conditions pertaining to non-cellular communications between UE115-band a non-cellular network (e.g., a WiFi network) while the UE is operating in a dual networking mode for steering, switching, or splitting traffic (e.g., ATSSS mode) between the non-cellular network and a cellular network (e.g., base station105-b). Monitoring the one or more first conditions may include monitoring signal-to-noise-plus-interference ratio (SINR) measurements at a receiver of UE115-bfor communications with the non-cellular network, a receive-power based on channel occupancy measurements, a signal variation, a channel quality, a radio frequency signature of the non-cellular network, or a combination thereof. Monitoring the one or more first conditions may include monitoring a Global Navigation Satellite System (GNSS) positioning of UE115-b, a Bluetooth connection of UE115-b, an application UE115-bis using, a quality of service requirement, or a combination thereof. Monitoring the GNSS positioning of UE115-bmay include determining whether UE115-bis near a cell-edge of the non-cellular network. Monitoring the Bluetooth connection of UE115-bmay include determining whether UE115-bis connected to a vehicle via the Bluetooth connection.

In some cases, monitoring the one or more first conditions may include monitoring one or more motion conditions associated with a motion of UE115-bin relation to the non-cellular network, the one or more motion conditions may include whether UE115-bis moving, whether the motion is localized, a type of the motion, whether the motion matches a pattern of the UE, whether UE115-bmatches a behavior expected during an application of UE115-b, or a combination thereof.

At410, UE115-bmay predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. Predicting the availability status of the non-cellular network may include predicting that the non-cellular network will become unavailable to UE115-bbased on at least one of the one or more first conditions. In some cases, UE115-bmay predict a time at which the non-cellular network will become unavailable to UE115-b.

In some implementations, UE115-bmay monitor one or more second conditions pertaining to cellular communications between UE115-band the cellular network (e.g., base station105-b) while UE115-bis operating in the dual networking mode, and may predict an availability status of the cellular network based on at least one of the one or more second conditions. Monitoring the one or more second conditions may include monitoring a throughput, a degree of quality of service satisfaction, a channel quality, an occupancy of a physical downlink control channel, interference measurements, a handover procedure, or a combination thereof associated with the cellular network. Monitoring the one or more second conditions may include monitoring a channel quality based at least on part on synchronization signal measurements, physical broadcast channel measurements, or a combination thereof. Monitoring the one or more second conditions may include performing power detection to determine an occupancy of a physical downlink control channel, where the power detection is indicative of cell loading. Monitoring the one or more second conditions may include monitoring for a handover from a private network to a public network, or vice versa.

UE115-bmay determine whether UE115-bis transmitting or receiving on-going traffic with the cellular network, where the one or more second conditions that UE115-bmonitors are based on the determination.

In some implementations, UE115-bmay input the one or more first conditions, the one or more second conditions, or a combination thereof into one or more algorithms, where the one or more algorithms may predict the availability status of at least one of the cellular network, the non-cellular network, or both. The one or more algorithms may include a neural network, and the neural network may be trained via online training or offline training. UE115-bmay adjust the one or more first conditions, or the one or more second conditions for predicting the availability status using the one or more algorithms. Adjusting the one or more first conditions, or the one or more second conditions may include adjusting a channel quality of the non-cellular network and comparing the adjusted channel quality to a threshold, where the adjusted channel quality may be based on loading of the non-cellular network. In some cases, UE115-amay input one or more backoff factors into the one or more algorithms based on alerts from a source other than a non-cellular network device. UE115-bmay compare the one or more first conditions, the one or more second conditions, or a combination thereof to one or more patterns, where the one or more patterns may include a radio frequency signature, motion patterns, past results indicative of situations in which UE115-bwent out of coverage of the cellular network or the non-cellular network, or a combination thereof.

In some cases, at415, UE115-amay transmit a message indicating that the non-cellular network will become unavailable, where the message may include a field indicating that the non-cellular network will become unavailable, an indication of a failure event associated with the non-cellular network, a report including one or more parameters associated with the non-cellular network, or a combination thereof. In some cases, the report may be an access availability and/or access unavailability report. In some cases, UE115-bmay determine a time to transmit the message indicating that the non-cellular network will become unavailable, where the time may be based on a predicted time that the non-cellular network will become unavailable, where the UE transmits the message at the time.

In some case, at420, UE115-bmay receive an indication for UE115-bto change dual networking modes in response to the message indicating that the non-cellular network will become unavailable, where the indication may configure UE115-bto switch to the cellular network, or may configure UE115-bto switch to a different dual networking mode.

In some cases, UE115-bmay determine to change dual networking modes, where the UE determines to switch to the cellular network, or to switch to a different dual networking mode based on predicting that the non-cellular network will become unavailable.

At425, UE115-bmay communicate in accordance with the dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction. Communicating may include communicating with the cellular network based on predicting that the non-cellular network will become unavailable to UE115-b. Communicating in accordance with the dual networking mode may be based on predicting the availability status of the cellular network.

In some cases, at430, base station105-bmay communicate with UE115-bin accordance with the dual networking mode in accordance with the indication.
