Packet Data Networking
Packet Data Networking is non-voice communications interfaces directly with
Intranet, Virtual Private Network (VPN), Extranet and Internet. Packet Data
Networking allows the service provider to become a point-of-presence for mobile
users on the Internet. This chapter will describe the fundamentals of Packet Data.
General
Non-Packet Data Network Service
Because Packet Data Networking uses equipment outside the iDEN
®
system, this
type of service may be restricted on a per-MS basis by provisioning and by
restricting radios at the EBTS with iHLR provisioning and OMC-R configurations.
Overview
Packet Data Networking uses the iDEN system dispatch calling functions and
infrastructure. An MS may travel freely throughout an iDEN system and teamed
roaming partners. If it is supported and provisioned, a user can originate or receive
Packet Data. Interconnect facsimile and Dial-up services are not supported.
• The MS sends and receives data directly.
• The EBTS determines the call as Packet Data and converts the radio link to
data packets.
• The MPS routes data packets.
• The DAP determines services and location.
• The MDG routes the data to and from the Internet.
• The Billing Accumulator (BA) collects time and bit-transfer information for
billing as desired by the service provider.
Packet Data Networking elements are shown in Figure 6-1.
