Data
Communication
Improvements
Data communications handling changes simplify MS configuration, increase
capacity, reduce data stream volume and improve routing failure recovery. The
improvement to data comminations include:
• Packet data bootstrap download — to simplify re-configuration of MS without
a PC or direct cable connection
• An increase in Mobile Data Gateway (MDG) — to increase MDG capacity
from 5,000 users to 15,000 users with a software change
• Packet Data Header Compression — to reduce the amount of data transmitted
on-air with IP header compression. (This requires IP header compression be
enabled on mobile during dial-up data networking)
• Mobile Internet Protocol (IP) Home Agent Redundancy — to help maintain a
data link if the master home agent fails by copying binding and routing
information to an assigned standby router.
Dispatch
Communications
Significant changes in Dispatch Call Processing have been introduced to improve
capacity, increase fleet size, allow cross fleet dispatch calls, and to reduce audio
degradation (dragging).
Cross Fleet Dispatch calling — a new identification scheme increases the number of
subscribers in a fleet and allow dispatch calls between different fleets.
New Dispatch Application Processor (DAP) hardware — a new version of the
dispatch switch controller and upgrade kits to convert exiting DAPs to the more
powerful configuration.
Home Location Register Portability — SR 8.0 improvements allow the HLR to be on
any T-DAP not a dedicated DAP.
Private Call Hang Time — a new dispatch call parameter to better define call tear
down and re-selection when a mobile travels across cell boundaries.
Enhanced Base
Transceiver Station
Improvements
The Enhanced Base Transceiver System (EBTS) has been expanded and upgraded to
increase frequency range, reduce recovery time and improve alarm and error
reporting
• Introduction of 821-825 MHz spectrum capabilities
• Dynamic adjustment of Transmit power on Base Radio Recovery or
switchover to redundant control channel Base Radios
• iDEN Monitor Unit (iMU) Alarm Module Control improvements in
monitoring and reporting of EBTS activity.
These changes are discussed in greater detail as required throughout this document.
Network
Management
Changes to the hardware and software of the Operations and Maintenance Center
(OMC) vastly improve Network Management. These changes are driven by the
phasing out of production of the S1000 and OMC 3000 workstations by the supplier.
These computers are going out of production so new hardware is being introduced to
act as OMC. The changes include:
• Introduction of the OMC 3500 platform
• The ability to control multiple frequency bands on one OMC
• The ability to network OMCs
