Abstract
Group call switch in trunking system needs a high tandem capacity, so several methods of group call switching will be analyzed and compared. The applications of IP soft switch and IP group multicast techniques improve the voice quality after switching, decrease the cost, and increase the usage ratio of network bandwidth. It will be the best choice for soft switch in next generation of trunking system. The necessary protocols and condition of IP network are also discussed according to the special character of trunking group call switch.
