Talk Group ID A Talk Group ID (Group ID) is a provider defined number that defines a functional
subset of a fleet. The type and number of groups in a fleet will vary with the
organization and requirements of each fleet. Each group has a dispatcher (user 0) that
is assigned as a logical control point for all dispatch communication.
Fleet Member ID A Fleet Member ID (Member ID) is a number assigned by the provider to uniquely
designate an MS. The ID is used to indicate a specific MS during dispatch calls, such
as the originator or target MS during a Private Call. It is also used to indicate the
specific MS transmitting in the PTT-ID service. Ultimately access and service are
designated by Fleet Member ID.
Site Specific
Parameters
Each EBTS on the iDEN system has unique identifiers to coordinate the activity and
maintain the integrity of the Radio Link. A list of Site specific parameter values is
transmitted on the BCCH by each iDEN cell to MSs on that cell. These values are
read and used by each MS as it executes its link control procedures (Chapter D,
Handover).
