Abstract: Geo-fence based alerts are provided in a wireless communications network. A first subscriber device (SD) in the wireless communications network determines its current location. The first SD detects a geo-fence trigger by determining, as a function of the determined current location and a stored geo-fence database, that it has either (i) crossed a geo-fence boundary into a first active geo-fence in the stored geo-fence database or (ii) is within the first active geo-fence and has not yet begun playing back an alert associated with the first active geo-fence. Responsively, the first SD identifies an alert associated with the first active geo-fence and begins playback of the alert associated with the first active geo-fence.

Abstract: Methods and systems are provided for supporting roaming wireless devices and roaming wireless groups with access controls. One exemplary method involves obtaining a set of permissions associated with a roaming device from its home radio system, obtaining a set of permissions for the roaming device from the visited radio system, merging the obtained sets of permissions, and responding to a request from the roaming device in accordance with the merged set of permissions for the roaming device within the visited radio system. Another exemplary method involves obtaining permissions associated with a roaming radio group from its home radio system, obtaining permissions for the roaming radio group from the visited radio system, merging the obtained permissions, and responding to a group service request for the roaming radio group in accordance with the merged set of permissions for the roaming radio group within the visited radio system.

Abstract: A method of managing objects residing in a communication system includes the steps of reading (201), by a network manager for a plurality of objects represented by at least one agent and residing in a communication system, a mapping of bitmap types to object types and monitoring (203) at least one communication resource between the network manager and the at least one agent. After service interruption on one communication resource of the at least one communication resource, and upon detecting (207) a return to service of the one communication resource, the network manager reads at least one bitmap from the at least one agent, wherein the at least one bitmap represents information relating to at least one object of the plurality of objects, and interpreting (213) the at least one bitmap by utilizing the mapping of bitmap types to object types in order to determine a status of the at least one object of the plurality of objects.

Abstract: A radio (101) affiliates with radio frequency sites (135, 145) based on a radio database (110) defining a group of valid site affiliations and a group of invalid site affiliations. Affiliations by the radio are controlled by a controller (120) with a controller database (160) defining a group of allowed site affiliations and a group of non-allowed site affiliations. When the controller database is altered, the radio database is updated to match the altered controller database. When the controller adds a site to its group of allowed site affiliations, it sends an updated radio database to the radio. When the controller adds a site to its group of non-allowed site affiliations, it waits until the radio requests permission to affiliate with that site and then sends an updated radio database to the radio. Upon receipt, the radio replaces its existing radio database with the updated radio database.

Abstract: A communication system (100) has automatic selection of talkgroups based on geographically defined areas. The system (100)includes wireless two-way communication units (120) capable of communicating with each other within a coverage area 205. A particular communication unit 120 is automatically caused to operate as a member of a particular talkgroup when that particular communication unit (120) is within a particular area of operation (207), which particular area of operation (207) is smaller than, and contained within, the coverage area (205).
