  • Patent number: 11800393
    Abstract: A knowledge base of cell information can be built and made available to one or more mobile devices. A mobile device with access to this cell information may proactively perform a radio signal scan at a frequency of an expected cell(s) that is/are indicated in the cell information (e.g., if the expected cell is associated with a serving cell and/or with a geolocation that corresponds to the current Global Positioning System (GPS) location of the mobile device). After performing the radio signal scan, the mobile device may store measurement information (e.g., signal strength) about the expected cell(s) in local memory of the mobile device, and, upon receiving an instruction from the serving cell, the mobile device may access the stored measurement information from its local memory, and may send the measurement information to the requesting serving cell.

  • Publication number: 20230312435
    Abstract: A radio access network (RAN) configured to support real-time communications over a Long-Term Evolution (LTE) connection is described herein. When a request for a data transmission is received and a real-time communication session over the LTE connection is established, the RAN utilizes the LTE connection, not a New Radio (NR) connection, for the data transmission. When a request for a further real-time communication is received and there is an active data transmission session over the NR connection, the RAN performs at least one of ceasing to allocate traffic to the NR connection for downlink or reconfiguring the data transmission session to send data over the LTE connection.

  • Publication number: 20230298605
    Abstract: Described herein are techniques, devices, and systems for selectively using a music-capable audio codec on-demand during a communication session. A user equipment (UE) may adaptively transition between using a first audio codec that provides a first audio bandwidth and a second audio codec (e.g., the EVS-FB codec) that provides a second audio bandwidth that is greater than the first audio bandwidth. The transition to the second audio codec may occur in response to determining that sound in the environment of the UE includes frequencies outside of a range of frequencies associated with a human voice, such as by determining that music is being played in the environment of the UE, which allows for selectively using a music-capable audio codec when it would be beneficial to do so.

  • Patent number: 11758512
    Abstract: A network indicator symbol may be presented on a display of a communication device to indicate a level of service currently supported by the communication device over a network to which the communication device is presently connected. Displaying the network indicator symbol sets the user's expectations for what types of services are currently supported. In some examples, the communication device may determine an appropriate network indicator symbol based on the device capabilities, the capabilities of the base station to which the communication device is connected, and the capabilities of neighing stations to the base station to offer E-Utran New Radio-Dual Connectivity based services.

  • Patent number: 11758051
    Abstract: Described herein are techniques, devices, and systems for providing an optimal voice experience over varying radio frequency (RF) conditions while using EVS audio codecs. A user equipment (UE) may adaptively transition between using a music-capable EVS codec (e.g., EVS-FB) as a default audio codec that provides a first audio bandwidth and a different EVS audio codec that provides a second audio bandwidth that is less than the first audio bandwidth. The transition to the different EVS audio codec may occur in response to determining a value indicative of a RF condition associated with a serving base station is less than a threshold value, which allows for providing preserving at least a minimal level of voice quality in degraded RF conditions.

  • Patent number: 11751055
    Abstract: Integrity protection is used to assist in ensuring the secure transmission of wireless data within a cellular network. Instead of performing integrity protection on each packet data unit (PDU) transmitted/received within a PDU session, integrity protection is performed on a portion of PDUs transmitted within a cellular network. For instance, partial integrity protection may be performed on at least one predetermined PDU (e.g., the first, second, fourth, . . . ) that is transmitted via a Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH) during a communication session. By performing partial integrity protection, user data may be transmitted more quickly throughout the cellular network, compared to performing full integrity protection, while still providing integrity protection.

  • Publication number: 20230262451
    Abstract: A mobile communication network receives capability information from a user equipment (UE) where the capability information indicates a version of the UE which the network uses to determine a 3GPP Release version of the UE. Based on the 3GPP release version, the network determines what type of system information (e.g., System Information Blocks (SIBs)) the UE requires, and transmits the required system information to the UE. Legacy UEs receive only legacy SIBs and non-legacy UEs receive one or more non-legacy SIBs in addition to the legacy SIBs.

  • Publication number: 20230224776
    Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to dynamically switch the primary cell (PCell) used by user equipment (UE) for carrier aggregation (CA) in 5G cellular networks. Instead of remaining anchored to an initially selected PCell, a different PCell may be dynamically selected based on different network conditions. The network conditions may include network congestion, network capacity, uplink speed, location of the UE, an activity of the UE (e.g., is the UE uploading or planning to upload data), and the like. As an example, the PCell may be selected from an n41 (2.5 GHz) cell and an n71 (600 MHz) cell. When the UE is close to the n41 cell, the n41 cell may be selected. When the UE is moving away from the cell center and toward the cell edge, the PCell may be switched from the n41 cell to the n71 cell.

  • Publication number: 20230217367
    Abstract: Techniques for dynamically adjusting Connected Mode Discontinuous Reception (CDRX) parameters are discussed herein. For example, a base station may receive information associated with downlink data to be sent to a user equipment (UE) and/or information associated with the UE itself. The base station may adjust CDRX parameters to be implemented on the UE based on the received information in order to maximize performance of the UE. In some examples, the base station may adjust CDRX parameters based on a traffic type (e.g., voice traffic, video traffic, data traffic, etc.) associated with the downlink data, UE state parameters associated with the UE, and/or Received Signal Strength Indicator (RSSI) data associated with the UE.
