ABSTRACT:
Embodiments of the present invention are related to a method and apparatus for determining whether each mobile station in a pre-defined group of two or more mobile stations is in compliance with acceptable location criteria. A group tracking server receives mobile station tracking information including a mobile station identifier for each mobile station. The server also receives current location coordinates corresponding to the mobile station identifier for each mobile station from a locator device. A relative location of each mobile station relative to one or more pre-determined targets the calculated. The acceptable location criteria for each mobile station relative to the one or more pre-determined targets is retrieved from a location criteria database. The calculated relative location of each mobile station relative to the one or more pre-determined targets compared with the retrieved location criteria to determine whether the calculated relative location is in compliance with the acceptable location criteria. A subscriber is then notified if the calculated relative location is in compliance with the acceptable location criteria.
