    Abstract: A method and system is provided for optimizing Radio resources during a VoLTE call when ROHC is enabled by indicating an IP-ID value using an identifier in an Initial and Refresh (IR) packet. During the VoLTE call, when value of a static IP-ID is zero, the ROHC compressor appends an identifier in the IR packet and enables the identifier for indicating the static IP-ID value to the ROHC decompressor. Further, the ROHC compressor sends the IR packet to the ROHC decompressor by enabling the identifier for indicating the static IP-ID value during the ROHC context. The ROHC decompressor receives the IR packet and determines the identifier in the IR packet. If the identifier is enabled in the IR packet then the ROHC decompressor sets the IP-ID value as zero during generation of decompressed IP header.

    Abstract translation: 提供了一种方法和系统，用于通过使用初始和刷新（IR）分组中的标识符指示IP-ID值来启用ROHC时在VoLTE呼叫期间优化无线电资源。 在VoLTE呼叫期间，当静态IP-ID的值为零时，ROHC压缩器在IR数据包中附加一个标识符，并使能指示静态IP-ID值的标识符给ROHC解压缩器。 此外，ROHC压缩器通过在ROHC上下文期间启用用于指示静态IP-ID值的标识符将IR分组发送到ROHC解压缩器。 ROHC解压缩器接收IR分组并确定IR分组中的标识符。 如果在IR数据包中启用了标识符，则在生成解压缩的IP报头期间，ROHC解压缩器将IP-ID值设置为零。

    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: A method and apparatus for enabling call sharing between devices are provided. The method includes installing a call sharing application in a user device and a first mobile device; establishing, by the user device, a connection with the first mobile device through the call sharing application for data transfer; receiving, by the first mobile device, a call request from the user device for establishing a voice call with a second mobile device; and performing, by the call sharing application in the first mobile device, at least one action in response to the call request from the user device.

    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.

    Abstract translation: 提供了一种用于在从长时间演进语音（VoLTE）呼叫切换到视频呼叫或反之亦然的过程中，在用户设备（UE）中保持鲁棒头部压缩（ROHC）状态的方法。 当VoLTE呼叫进行中，如果用户将VoLTE呼叫切换到视频呼叫，则RTP头信息从通信处理器（CP）发送到应用处理器（AP）。 ROHC压缩器使用用于视频呼叫的现有内置上下文继续RTP分组的压缩。 此外，当视频呼叫正在进行时，如果用户将视频呼叫切换到VoLTE呼叫，则RTP头信息从AP发送到CP。 通过在AP和CP之间交换RTP头信息来重用ROHC上下文。
