Abstract: A method of wireless communication includes initiating handover of a first call from a source network to a target network. The first call is associated with first header information. The method also includes receiving a message indicating a change of Internet protocol (IP) address to a new IP address during the handover. The method further includes releasing resources associated with the first call, in response to receiving the message. The method includes registering the new IP address with the target network, and initiating a second call with the first header information. The method also includes replacing the first call with the second call and the new IP address.

Abstract: Disclosed are techniques for wireless communication. In an aspect, UE communicates data associated with a communication session over a first RAT (e.g., LTE, NR, WLAN, etc.) in accordance with a first set of performance parameters (e.g., codec, QoS, bitrate, bandwidth, etc.). UE performs, during the communication session, an inter-RAT handover from the first RAT to a second RAT (e.g., LTE, NR, WLAN, etc.). UE transmits a re-INVITE over the second RAT in response to the inter-RAT handover. UE receives an indication of a second set of performance parameters (e.g., codec, QoS, bitrate, bandwidth, etc.) in response to the re-INVITE. UE communicates data associated with the communication session over the second RAT in accordance with the second set of performance parameters.
