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.

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.

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
