摘要： Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

摘要： Embodiments include systems and methods for wireless device signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the wireless device of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the wireless device supports a CRS function, and including an indication in a response to the INVITE that the wireless device supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the wireless device only if the wireless device indicates CRS functional capability.
