Method and apparatus for managing radio system attributes for communication units
First Claim
1. A method for managing a radio communication system in a multi-site trunked environment, the method comprising the steps of:
- providing a plurality of communication sites managed at least in part by a central controller;
providing at least one communication unit affiliated with each communication site;
maintaining, for each communication site, a site database including attributes for the at least one affiliated communication unit;
maintaining, for the central controller, a central database including attributes of communication units affiliated with the plurality of communication sites;
determining that the central database does not contain up-to-date information based on the central controller not being available to receive updated communications from the communication units;
building the central database from the respective site databases when the central database does not contain up-to-date information, including the steps of;
requesting, by the central controller, at least a subset of attributes from the site database for each communication site; and
updating the central database using at least the subset of attributes received.

Abstract
A radio communication system (100)provides for management of system attributes for communication units. The system includes communication sites (111, 112, 113) managed at least in part by a central controller (110), and communication units (121, 122, 123, 124) affiliated with each communication site (111, 112, 113). Each communication site (111, 112, 113) maintains a site database (305) including attributes for affiliated communication units. The central controller (110) maintains a central database (205) which includes attributes of communication units affiliated with the communication sites managed by the central controller (110). The central controller (110) receives at least a subset of attributes from the site database (305) of a communication site, and updates the central database (205) accordingly.

6. A method for managing a radio communication system having a plurality of subscriber units operable in a multi-site trunked environment, the method comprising the steps of:
-
providing a plurality of trunked communication sites, wherein at least some of the communications sites have at least one subscriber unit, selected from among the plurality of subscriber units, affiliated therewith; providing a central controller for managing the plurality of trunked communication sites; maintaining, at each communication site, a site database having attributes, including an identifier and talk group association, for the at least one affiliated subscriber unit; maintaining, at the central controller, a central database having attributes, including identifiers, talk group associations, and site affiliation, for subscriber units affiliated with the plurality of trunked communication sites; determining that the central database does not contain up-to-date information based on the central controller not being available to receive updated communications from the subscriber units; building the central database from the respective site databases when the central database does not contain up-to-date information, including the steps of; requesting and receiving, by the central controller, identifiers, talk group associations, and site affiliations for subscriber units, from each communication site; determining that a database conflict exists when the central controller receives conflicting information for a particular subscriber unit, from at least two communication sites; and when a database conflict exists; initiating, through the at least two communication sites, procedures to get updated attributes from the particular subscriber unit retrieving updated attributes from the particular subscriber unit; updating the central database and the site databases for the at least two communication sites with the updated attributes. - View Dependent Claims (7, 8)
