Location-based call management for geographically-distributed communication systems
First Claim
1. In a communication system providing group dispatch communication capability for a plurality of communication devices linked to a controller by one or more communication paths, a method comprising the controller performing steps of:
- receiving, from a sourcing communication device of the plurality of communication devices, a message comprising one or more packets;
determining, based on a priority of the sourcing communication device, a message priority;
sending the message, via one or more of the communication paths, to a number of recipient communication devices of the plurality of communication devices, if the recipient communication devices are not already being sent a higher priority message.

Abstract
Location-based call management methods for geographically-distributed communication systems, including conventional (FIG. 1) and trunking (FIG. 3) systems operable in full duplex mode. A base station controller (111) of a conventional system receives (202) a message, determines (204) a message priority and sends (210, 214, 220) the message to recipient devices selected from among a console (122), local base station (101) and adjacent base station(s) (102, 103) based on the message priority. A zone controller (308) of a trunking system determines an associated site (301) and one or more adjacent sites (302, 303) for a prospective talkgroup call and, based on availability (406, 416, 428) of resources, assigns (424, 432) site(s) to the call. A mobile communication device (320) determines (506, 510) a selected site and adjacent site(s) and respective talkgroups, affiliates (508) with the selected site talkgroup and enters (512) the adjacent site talkgroup(s) in a scan list. Thereafter, the communication device is able to receive (518) calls for the affiliated or adjacent site talkgroups.

9. In a communication system including a plurality of base sites having geographically distributed coverage areas, the base sites providing group dispatch communication capability for communication devices distributed among the coverage areas, a method comprising:
-
receiving, from a first member of a first talkgroup, a request for a prospective talkgroup call;
identifying a site of the plurality of base sites associated with the prospective talkgroup call, defining an associated site;
determining an availability of resources at the associated site;
in response to a positive determination of availability at the associated site, assigning the associated site to support the call;
identifying one or more sites of the plurality of base sites in a window of proximity to the associated site, defining adjacent sites;
determining an availability of resources at the adjacent sites; and
in response to a positive determination of availability at one or more of the adjacent sites, assigning the one or more adjacent sites to support the call. - View Dependent Claims (10, 11, 12, 13)

14. In a communication system including a plurality of base sites having geographically distributed coverage areas, a method comprising a communication device eligible for movement between the coverage areas performing steps of:
-
selecting a local site of the plurality of base sites, thereby defining a selected site;
identifying a talkgroup associated with the selected site;
registering affiliation with the talkgroup, the talkgroup thereby defining an affiliated talkgroup;
identifying one or more sites of the plurality of base sites in a window of proximity to the selected site, defining one or more adjacent sites;
identifying, for each of the one or more adjacent sites, an associated talkgroup, thereby defining one or more adjacent site talkgroups;
upon receiving a call grant message indicative of a talkgroup call for the affiliated talkgroup, selecting a communication resource that enables the communication device to receive the call; and
upon receiving a call grant message indicative of a talkgroup call for an adjacent site talkgroup, selecting a communication resource that enables the communication device to receive the call unless the communication device is presently receiving a call for the affiliated talkgroup. - View Dependent Claims (15, 16, 17, 18)
