In telephony, GoTa or “Global Open Trunking Architecture” is a CDMA-based digital trunking system. The GoTA system was developed by ZTE, a Chinese manufacturer. It was approved as a CCSA standard[1] by the China Ministry of Industry and Information Technology in 2008 and accepted as an international standard by the ITU in 2012.[2] The GoTA system can be used for both private and public trunking network applications.

GoTa is capable of providing a variety of trunking services:

In addition to trunking service, GoTa can provide value-added services such as short messages, location-based services and other data services. The original GoTa standard was developed for the 800 MHz band. GoTa is adapted to work in the 450 MHz band as well.


PTT PoC or Push to talk over Cellular is a feature similar to walkie-talkie that is provided over a cellular phone network.
