Method and apparatus for distance-based notification in a two-way wireless communication system

摘要

A group selected from a plurality of portable subscriber units (122) is defined (402), and a plurality of locations corresponding to members of the group are identified (404) by a controller (112) in cooperation with a base station and the group members. The controller determines (406) from the plurality of locations at least one distance between selected ones of the members, and sends (408) a notification when the at least one distance satisfies a predetermined set of rules.
