August 2003, the Open Mobile Alliance (OMA) put forward the basic standards of Push-to-Talk over Cellular (PoC). June 2005,published OMA PoC V1.0 technical regulations.
At the end of 2016, USA famous consulting company. Frost & Sullivan published the white paper of PoC walkie talkie technology development trend, named《Push-To-Talk over Cellular:The Next Generation for Land Mobile Radio》,caused wide attention.
