Fleet
A Fleet is a logical organization of people and/or systems (users) that require
mobility. In the broadest terms, a fleet is a subscriber. A subscriber can be:
• An individual
• A business
• An agency
• A government or municipal department
• An extended family
• Any functional organization with members that communicate with each other.
The iDEN system provides fleet-based communications with Dispatch call
processing (half-duplex mode). Half-duplex mode is also called Push-to-Talk (PTT)
because a button is pushed when transmitting (talking) and the same button is
released when receiving (listening).
TalkGroup
Each fleet may contain subsets of localized communication. Like lines a multiline
telephone each MS may be linked to a talkgroup that includes other fleet members.
Individuals or groups may be selected to share in resources to engage in
conversation. Large groups can be defined and users may subscribe to
memberships in the group. The number of groups and members is flexible. Groups
are tailored to fleets and marketing plans. How fleets and talkgroups in the fleets are
organized in provisioned in the Dispatch call processing databases.
Users
Users are individuals with network devices (radios, phones and similar devices).
Users must be provisioned before they may use the system.
