  • Patent number: 12034779
    Abstract: Maintaining a registered state via server-managed notifications is described herein. In an example, server(s) can receive an indication from an application associated with a device, the indication can identify a response to a registration request sent by the application for registration with a service provider. Based at least partly on the indication, the server(s) can start a first timer associated with a first predetermined time interval after which the server(s) are to send a first notification to the application. The server(s) can determine, based at least in part on the first timer, a lapse of the first predetermined time interval and can send the first notification to the application. The first notification can cause the application to transition from an inactive state to an active state, and send a new registration request to register with the service provider to maintain a registered state.

  • Patent number: 11785434
    Abstract: Systems and methods for providing additional functions on a user equipment (UE) with an over-the-top (OTT) application are disclosed. The systems and methods can enable the UE to register with a telephony application server (TAS) using a subscriber identity module identification (SIM ID). The registration can enable communications directed to a cellular number, for example, to be redirected to the UE via a Wi-Fi connection through a wireless residential gateway (WRG). The OTT application can enable the UE to utilize the SIM ID to send and receive communications via a cellular network, an internet protocol (IP) network, or both. The OTT application can also provide applications and capabilities that are not otherwise available on the UE. An OTT settings graphical user interface (GUI) can enable the user to dynamically configure how communications are sent and received in response to changing conditions or preferences.

  • Patent number: 11729674
    Abstract: A light-weight solution for media handovers between different Radio Access Technologies (RAT) is provided. A user may switch from Wi-Fi to Cellular Data (e.g., LTE/4G/3G/ . . . ), from Cellular data to Wi-Fi, and the like. In contrast to a “make-before-break” design for switching between RATs, the technologies described herein are a “break-before-make” design. When a change in a RAT is detected, an application on the computing device utilizing the connection is notified of the change. Instead of removing connection information, the connection is maintained for a configurable period of time such that the application can re-register with the network to continue the communication session. During a transition to a second RAT, the application provides one or more notifications to the user of the change in RAT. For instance, a graphical user interface (GUI) can be displayed showing the change and/or a tone can be played indicating the change in the RAT.

  • Patent number: 11050801
    Abstract: During a call session between a first user equipment (UE) and a second UE managed by a call application server, the first UE can send a request to a conference application server to upgrade the call session to a meeting session. The conference application server can set up the meeting session. Once the first UE and the second UE have joined the meeting session with the conference application server, the first UE and the second UE can end their legs of the original call session with the call application server. The first UE and the second UE can transition their user interfaces from a call mode to a meeting mode upon joining the meeting session, such that users are seamlessly transitioned from a call to a meeting.

  • Patent number: 11032333
    Abstract: Systems and methods for enabling one-way video calling are disclosed. The system can enable user equipment (UE) with varying capabilities to communicate in an asymmetrical manner. A UE receiving an incoming two-way video call can request that the call be “downgraded” to a one-way video-in call, a one-way video-out call, or even an audio-only call. The system can include a multi-way video graphical user interface (GUI) to enable the user to choose between accepting an incoming two-way video call or requesting a different type of call (e.g., a one-way video call or an audio-only call). The system can also include a call initiation GUI to enable users to select between two-way video, one-way video, or audio-only for outbound calls. The system can also include a call modification GUI to enable users to modify the parameters for an incoming call prior to initiating the call.

  • Patent number: 11012576
    Abstract: Systems and methods for providing additional video call transfer functionality are disclosed. The systems and methods can enable a video call between a first user equipment (UE) and a second UE to be transferred to a video call between the second UE and a third UE either a video call or an audio call. The systems and methods can also enable the third UE to accept a transferred video call or to request that the video call be downgraded to an audio call. The systems and methods can incorporate a multimedia resource function (MRF) to connect to the second UE while the transfer is being negotiated and effected. The MRF can provide an audio stream and a video stream to the second UE to provide a “video hold” feature—to prevent the video call from dropping to an audio call automatically or dropping altogether.
