Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.

Abstract: A wireless voice call may be established between an originating user equipment (UE) and a terminating UE, via a cellular network, using preconditions. The originating UE may transmit an invitation for a packet-switched wireless voice call, beginning a first period of time. The terminating UE may cancel the invitation in response to determining that a first precondition, such as establishment of a dedicated bearer between the originating UE and the cellular network, is not satisfied within the first period of time. The first period of time may be interrupted in response to determining that the first precondition is satisfied, and a second period of time may then begin. The cellular network may cancel the invitation in response to determining that a second precondition, such as establishment of a dedicated bearer between the terminating UE and the cellular network, is not satisfied within the second period of time.
Abstract translation: 可以使用前提条件通过蜂窝网络在始发用户设备（UE）和终端UE之间建立无线语音呼叫。 始发UE可以在第一时间段开始发送分组交换无线语音呼叫的邀请。 响应于确定在第一时间段内不满足诸如始发UE和蜂窝网络之间的专用承载的建立的第一前提条件，终止UE可以取消邀请。 响应于确定第一前提条件得到满足，第一时间段可能被中断，然后可以开始第二时间段。 蜂窝网络可以响应于在第二时间段内确定第二前提条件，例如在终止UE和蜂窝网络之间的专用承载的建立不被满足而取消邀请。

Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.

Abstract: A user equipment (“UE”) connected to a first network that performs methods including receiving a page from the first network indicating an incoming voice call, when it is determined the voice call was not successfully connected, incrementing a value of a counter and when the value satisfies the threshold, switching from the first network to a second network. Another method includes originating a voice call via the first network, when it is determined the voice call was not successfully connected, opening a socket connection with the first network and attempting to re-originate the voice call via the first network. Another method includes determining whether the UE has switched a connection from a first network to a second network and when it is determined that the UE has switched the connection to the second network, initiating an action by the UE.
