Abstract: An apparatus and method are provided for managing call continuity at a user equipment (UE). The method includes initiating, by the UE, a timer, when a call is active; detecting, by the UE, that the timer exceeds a timeout threshold; and sending, by the UE, to a network entity, a message for triggering a handover procedure before the timer expires, in response to detecting that the timer exceeds the timeout threshold.

Abstract: Disclosed are a method and apparatus for packet communication using header compression. The method includes applying a header compression protocol to generate a packet to be transmitted, determining whether the packet is dropped in a transport layer, and transmitting, if it is determined that the packet is dropped, a full packet having an uncompressed header.

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.
