Abstract
A method for retaining a Robust Header Compression (ROHC) state in a User Equipment (UE) during switching from a Voice over Long Term Evolution (VoLTE) call to a video call or vice versa is provided. When the VoLTE call is in progress and if a user switches the VoLTE call to the video call, then the RTP header information is sent to an Application Processor (AP) from a Communication Processor (CP). The ROHC compressor continues the compression of the RTP packets using the existing built context for the video call. Further, when the video call is in progress and if the user switches the video call to the VoLTE call, then the RTP header information is sent to the CP from the AP. The ROHC context is reused by exchanging the RTP header information between the AP and the CP.
