1. A system for changing a default talk group of a mobile communication terminal, the system comprising:
- a server; and
a mobile communication terminal,wherein at least one of the server and the mobile communication terminal includes a memory configured to store talk group information including at least first and second predefined talk groups, mobile communication terminals included in the first and second talk groups, and geographical locations corresponding to each of the first and second talk groups,wherein the server is configured to receive a current location of the mobile communication terminal, transmit a message requesting the mobile communication terminal to change a default talk group of the mobile communication terminal from the first talk group to the second talk group when the server determines the location of the mobile communication terminal is in a geographical location corresponding to the second talk group and being defined in the stored talk group information, andwherein the mobile communication terminal is further configured to transmit a message to the server either approving or disapproving of a change to the default talk group.
