Abstract

Private trunked radio systems, such as those used by state and local government, ohen need to temporarily reallocate talkgroup resources due to unusual circumstances or special events. A flood, for example, might create a temporary need for the police to communicate with the water and electric departments.

TEMPORARY TALKGROUP ALLOCATION IN A SHARED RADIO SYSTEM

by Marie Gilbert and John Gilbert

required to allow users to easily allocate their own temporary talkgroups.

BACKGROUND

  Private trunked radio systems, such as those used by state and local government, ohen need to temporarily reallocate talkgroup resources due to unusual circumstances or special events. A flood, for example, might create a temporary need for the police to communicate with the water and electric departments.

  In a private trunked radio system this would be accomplished by a dispatcher at a workstation who would originate data messages to mobile and porta- ble radios in the field. These "dynamic regrouping" messages would temporarily change the program- ming of the radios to allow operation on talkgroups that might otherwise be unavailable. When the spe- cial event has passed another command would be issued to return the radios to their original program- ming. This feature called "Dynamic regrouping" is common in the private radio systems environment.

  In shared trunked radio systems, a user typi- cally purchases airtime from a service provider. Users of shared radio systems are ohen businesses such as service or delivery companies. These users typically don't have large communications centers staffed with trained dispatchers, nor do they have a need for advanced features such as dynamic regrouping.

SOLUTION

Temporary talkgroups for shared radio systems could be allocated using the following method:

1. A special telephone number is provided to trunked radio users. With a touch tone based menu, a user can select a temporary talkgroup function and iden- tify a start and end time and day for the tempo- rary talkgroup.

2. The system can respond with an activation code that the person writes down or remembers.

3. At the requested day and time, the radio system...
