Abstract
A method of selectively connecting group phone calls to a roaming mobile station. A mobile station is provided for use in a wireless communication system for selectively originating and receiving group phone calls. The mobile station includes a memory storing a plurality of group phone numbers for each group of which the mobile station is a member, and roam originate and receive enable flags for each group phone number. The roam originate and receive enable flags are selectively settable between first and second states to either permit or prohibit group calls to be originated from, or received at, the mobile station while the mobile station is roaming.
