  • Publication number: 20220264374
    Abstract: Systems and methods described herein use group segmentation of applications (referred to herein as “slicing classes”), based on common service requirements, to allow carriers to assign UE traffic to network slices. A UE stores slicing class definitions for use with UE Route Selection Policies (URSP). Each of the slicing class definitions include network quality of service (QoS) characteristics that are applicable to network traffic for multiple software applications. The UE maps the software applications to corresponding slicing class identifiers associated with the slicing class definitions. The UE also stores URSP rules for associating a slicing class identifier with a network slice identifier. A UE operating system sends, to a modem, one of the slicing class identifiers for an application that is requesting attachment to a wireless network. The modem sends a registration request with a selected network slice identifier based on the received slicing class identifier and the URSP rules.

  • Patent number: 11382157
    Abstract: Systems and methods described herein improve a customer experience for non-standalone cellular networks by displaying a secondary cell group (SCG) network icon after data activity ends while a user device likely remains in SCG coverage. When connected to the SCG, the user device detects inactivity on the connection and initiates a first timer, based on the detecting, while continuing to present an SCG-related icon. If the first timer expires while the user device is in an idle state, the user device initiates a second timer, while continuing to present the SCG-related icon. If the user device detects an active connection before expiration of the second timer, the user device initiates a third timer while continuing to present the SCG-related icon. If the user device fails to detect a connection to the SCG before expiration of the third timer, a master cell group (MCG)-related icon is displayed.

  • Publication number: 20220141704
    Abstract: In some implementations, a network device may monitor a communication session associated with a user equipment and a network. The network device may determine a service-level identifier associated with a subscription of the user equipment, wherein the subscription is for a particular level of service that is to be provided by the network to the user equipment. The network device may determine that a performance metric associated with the communication session satisfies a performance threshold associated with the particular level of service. The network device may provide the service-level identifier to the user equipment based on the performance metric satisfying the performance threshold, wherein the service-level identifier enables an indication that the user equipment is receiving the particular level of service to be displayed by the user equipment.

  • Publication number: 20220086656
    Abstract: Systems and methods provide reliable voice connections dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts a parameter barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.

  • Publication number: 20210314818
    Abstract: A network device, of a fifth generation (5G) radio access network, may establish a connection or a session with a user equipment connected to a Wi-Fi network. The network device may determine an indicator indicating whether a 5G network preference is in effect based on a subscription of the user equipment and may provide the indicator to the user equipment. The network device may maintain the connection or the session with the user equipment when the indicator indicates that the Wi-Fi network is not preferred for Wi-Fi offload and may receive traffic from the user equipment when the indicator indicates that the Wi-Fi network is not preferred for Wi-Fi offload.

  • Patent number: 11134441
    Abstract: A device may receive signal information associated with a wireless signal or charge information associated with a charge level. The signal information may indicate a signal strength of the wireless signal. The charge information may indicate the charge level of a battery of the device. The device may determine whether the signal strength or the charge level satisfies a threshold. The device may configure a parameter or a setting of the device to cause the device to operate according to a long term evolution (LTE) category based on determining whether the signal strength or the charge level satisfies the threshold. The LTE category may be different from a default LTE category of the device and may define an uplink/downlink capability specification. The device may attach to a network in association with configuring the parameter or the setting to cause the device to operate according to the LTE category.

  • Publication number: 20210297919
    Abstract: A user equipment (UE) may establish a wireless connection with a WiFi network, and may perform a measurement associated with a fifth generation (5G) ultra-wideband radio access network. The UE may determine whether the measurement satisfies a signal strength threshold, and may selectively perform a first action or a second action based on whether the measurement satisfies the signal strength threshold. The first action may include providing an indication of an availability of the 5G ultra-wideband radio access network, for display, when the measurement satisfies the signal strength threshold. The second action may include maintaining the wireless connection when the measurement fails to satisfy the signal strength threshold.
