System and method for transmitting and receiving multimedia content between the caller and the callee during ring time of a voice call

A system for transmitting real time and live multimedia content from a caller mobile device to a callee mobile device during ring time of a voice call, the system comprising:

• a non-transitory storage device;
• and
• one or more processors coupled to the non-transitory storage device and operable to:
• initiate, through a call initiation module when executed by the one or more processors, the voice call through a cellular network, from the caller mobile device to the callee mobile device;
• the system characterized in that comprising:
• a data channel establishment module, which when executed by the one or more processors, establishes a data channel over a data network between said caller mobile device and said callee mobile device,
• said data channel being established during ring time of the voice call and is disconnected after voice call based connection is established between the caller mobile device and the callee mobile device,
• wherein said data channel is established simultaneously along with call process by modifying command that executes mobile device hardware to activate said data channel and call process together;
• wherein said data channel is established only when phone number of the callee mobile device is present in a defined repository or is verified through an authentication mechanism, and
• wherein establishment of said data channel over the data network and establishment of the voice call based connection over the cellular network is performed simultaneously without interfering with each other;
• and
• a data channel based multimedia content transmission module, which when executed by the one or more processors, transmits and receives between the caller mobile device and callee mobile device,
• the real time and live multimedia content which originates from or is stored in said caller mobile device or said callee mobile device and not from any third party sources or servers, over the established data channel.
