Abstract: A method and a system for handling audio packets in a Voice over Long Term Evolution (VoLTE) call by a User Equipment (UE) when Robust Header Compression (ROHC) is enabled are provided. The Transmission Control Protocol/Internet Protocol (TCP/IP) layer provides the VoLTE call properties to the ROHC compressor. The TCP/IP layer receives the audio packets from audio engine and sends the Real-time Transport Protocol (RTP) packets to a ROHC compressor. Further, the ROHC compressor compresses the Internet Protocol/User Datagram Protocol (IP/UDP) headers and a RTP header. The ROHC compressor sends the compressed RTP data along with a payload to the network in the UpLink (UL) data path. During DownLink (DL) data path, ROHC decompressor receives compressed ROHC packet from network. The ROHC decompressor ignores the construction of IP/UDP headers for the compressed data.

Abstract: Methods, systems, and apparatuses (including, but not limited to, User Equipment (UE) and Base Stations) for a UE to control a packet header compression function in a communication system are described. In one method, if a predetermined condition is satisfied while the packet header compression function is enabled, the UE transmits a request for disabling the packet header compression function to a Base Station (BS), and, if a response is received from the BS, the UE disables the packet header compression function.
