GMG TETRA radio asset manager

GMG's DAAM TETRA radio asset manager (RAM) enables a fleet of radios to be dynamically assigned when a radio terminal is used as a shared resource, thereby substantially lowering the number of radios a company would need to keep in the asset pool. Radio users are assigned a dedicated ‘user number’ so that monitoring who is talking or contacting this individual user becomes easy. The user number also becomes the TETRA phone number, a unique number depicting that user.

BEA’s anti-aliasing protocols enable radio users to perform the following tasks: Log In, which has the effect, if successful, of associating the terminal with the user; Log Out, which has the effect, if successful, of disassociating the terminal with the user currently associated with it; and DGNA, whereby the successful login can associate the user with a predefined talk group list. This list can be dynamically allocated to the user’s terminal number in Dynamic Group Number Assignment.

The user will receive responses from the above actions to indicate success or failure. The reassignment of terminals to the user is indicated by the user number and user name reference appearing or removed from the terminal screen accordingly.

The reassignment of a terminal will also apply a specific name and user profile in the network subscriber database. Subscriber profiles contain a list of features and functions each user has on the TETRA network. Management can now assign specific profiles to users that get applied to the radio terminal they are using.

Profiles include (but are not limited to): access list of talk groups; access list of sites (geographic); access to make or receive individual call services; access to make or receive telephone call services; access to SDS messaging services; priority level controls (low, medium, high, pre-emptive); and access to Packet Data services.
