  • Publication number: 20240334319
    Abstract: Embodiments described herein relate to dynamic selection of radio access technologies (RATs) available for use by 5G wireless devices. Managing selection of RATs to use by a 5G (and 4G LTE) capable wireless device can improve performance, e.g., when an application requires a higher throughput and a 5G SA connection underperforms a 5G NSA connection or a 4G LTE connection. Wireless devices can provide geolocation tagged cellular wireless network information, e.g., network performance measurements and observed properties, to network-based servers that collate and organize the crowd-sourced cellular wireless network information into a location database. The wireless device can use the cellular wireless network information of the location database for a geolocation at which the wireless device is operating to estimate performance for alternate wireless connections and compare to measured performance of a currently used wireless connection to determine whether to switch wireless RAT connections.

  • Patent number: 12022493
    Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

  • Publication number: 20240090047
    Abstract: This Application sets forth techniques for managing the cellular connectivity state of a submerged wireless device. The wireless device can include sensors that analyze environmental conditions to determine when the wireless device is (or is not) submerged underwater as well as at what depth the wireless device is submerged underwater. The sensors can also determine different types of aquatic activity in which a user of the wireless device is currently engaged, such as swimming, snorkeling, free diving, and scuba diving. In turn, the wireless device can utilize this information to manage its cellular connectivity state in order to avoid wasteful consumptions of energy. In particular, the techniques enable the submerged wireless device to eliminate any existing cellular connection as well as connection reattempts so long as they are unlikely to succeed. Moreover, the techniques enable the wireless device to execute connection reattempts when they are appropriate and likely to succeed.

  • Publication number: 20230397095
    Abstract: A device executing a low-latency application that uses a Wi-Fi link may switch from the Wi-Fi link to using a second link to a multi-subscriber (MSIM) PHS device. The device may access, via the second link, any one of multiple cellular links, each cellular link corresponding to a different respective cellular subscription of multiple subscriptions used by the PHS device. The application executing on the device may thus use a preferred cellular link from among the multiple cellular links. The preferred cellular link may be determined based on parameters corresponding to the plurality of cellular links for each respective cellular subscription. The parameters may be obtained from a location database. The preferred cellular link (which may presently correspond to a primary subscription) on the PHS device may be switched to be a different cellular link (which may correspond to a non-primary subscription) during execution of the application on the device.

  • Publication number: 20230076738
    Abstract: Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

  • Patent number: 11582669
    Abstract: Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.
