SMARTNETKMARTZONE AND OTHER WIDE-AREA COMMUNICATION SYSTEM AFFILIATION GROUPS

Invention: Allowing a subscriber to participate in a talkgroup on an "Affiliation-Only " basis. This feature permits the subscriber to retain all TG ( talk- group) features except that which requires them to receive incoming dispatch calls. The feature can be either subscriber enabled, TG strapped, or both.
Today's radio software now allows for many feature's other than dispatch that do not need a spe- cific channel allocated for the current talkgroup while the radio is sitting idle in a wide area system. Sometimes the radio user has their radio just to receive pages, private/selective calls, Dynamic Regroups, Patches, Scanning, and phone calls. To do these features, however, the radios need to Affiliate with the central system controller. This affiliation, however, causes the system to also steer talkgroup calls to that cell, even though the radio listener does not want to hear them. We need some way to get around this resource wasting problem, and it needs to be specific and controllable at the radio level because only the user can tell what is needed at what time.
Today's larger wide area communication sys- tems need updated methods for how subscriber's are broken up into groups. The current schemes allow for over-taxing of system resources. A Wide area system knows where different subscribers are based on an affiliation sent to the system's central controller from the radio. When a radio is in range of a specific cell, it will cause a channel to be allo- cated for all calls within that radio's specific talk- group or subfleet. The radio has no distinct method
of communication with the central controller that can simply 'Say where it is' without bringing up valuable system resources.
The end result of all this is that channels and frequencies are being wasted. Channels are being used that are unnecessary which causes more busy rejects and slower PTT and system access times. One large "wide area" system recently noticed 40% busy rejects because of this. Because of unneces- sary dispatch call steering, other more important dispatch calls could not go out immediately.
INVENTION DESCRIPTION: AFFILIATION GROUP
Radios need to communicate with the central controller in a way that does not bring up valuable cell...
