SRVCC HANDOVER INDICATION FOR REMOTE PARTY TO VOICE CALL

摘要

A method for providing indication of an SRVCC handover is disclosed. The method can include a first wireless communication device participating in a voice call with a second wireless communication device via a connection between the first wireless communication device and a first network. The method can further include the first wireless communication device determining a condition indicative of an impending SRVCC handover of the first wireless communication device from the first network to a legacy network. In response to the condition, the method can additionally include the first wireless communication device formatting a message including an indication that the first wireless communication device is going to perform the SRVCC handover and sending the message to the second wireless communication device prior to performance of the SRVCC handover.

1. A method for providing indication of a single radio voice call continuity (SRVCC) handover, the method comprising a first wireless communication device:
participating in a voice call with a second wireless communication device via a connection between the first wireless communication device and a first network servicing the voice call as a voice over Internet protocol (VoIP) call via a packet switched domain; determining a condition indicative of an impending SRVCC handover of the first wireless communication device from the first network to a legacy network, wherein the legacy network comprises a circuit switched domain configured to service the voice call as a circuit switched call after completion of the SRVCC handover; and in response to the condition:
formatting a message comprising an indication that the first wireless communication device is going to perform the SRVCC handover; andsending the message to the second wireless communication device prior to performance of the SRVCC handover.
