Global
Global refers to the worldwide, multi-provider, Public Telephone Switched Network
(PSTN). The telephone services available worldwide may be accessed from the
iDEN system using Interconnect calling. When the iDEN system uses the PSTN
(Interconnect) system, the rules and procedures of the PSTN are used. Interconnect
calling is the access to land-line systems and the services available and emerging in
the public switched environment. Global Two-Way (Dispatch) communications,
while currently not available, is emerging technology.
Region
A Region is a large geographic area that is usually associated with more than one
market or, more than one urban area. Just as urban areas tend to be adjacent and
overlap, so do service provider coverage areas. A single service providers provides
services by regions. A service provider may have adjacent or overlapping markets
that can be linked to provide contiguous service across the areas. Regions may be
covered by either Interconnect and Dispatch calling.
Domain
A Domain is an optional logical division of a region. This is usually defined by
marketing and sales strategies as a fleet-based geographical area. The intent is to
subdivide the region into smaller areas based on expected usage patterns.
Domain 0 is a system-wide domain. The default for Domain 0 is all service areas.
There can be up to 50 domains can be assigned. Each domain may contain up to 254
service areas and represents the area of operation for a fleet or fleets. A Domain:
• Can not split a service area
• Can cross MSO boundaries.
• Should be geographically contiguous and should not intertwine or overlap.
• Should conform to obvious geographic - demographic borders
• Should have borders in areas of zero, or few subscribers
• Should make use natural obstacles that constrain subscriber movement
To minimize movement of subscribers between domains, domain borders should
avoid major roads, highways, and thoroughfares. Obstacles like rivers, mountain
ranges, and diverse geographic areas separated by a lack of contiguous RF coverage
are good boundaries.
Users within a domain tend to stay within its borders. A business' fleet will normally
stay within a domain throughout the course of the work day.
Service Area
A Service Area is dispatch only and is defined in provisioning by the subscriber and
user databases. A service area is a group of Dispatch Service Areas (DLAs) that
define a range of operation. Multiple service areas may be defined. Service Areas
may overlap. Users in a service area tend to stay within its borders. A business' users
that travel outside the service area will not be able to obtain dispatch service.
