Introduction
This document provides an overview of the structure of the TIA
standards describing protocols for interoperable communications
over wireless broadband systems.
In 2011 the Emergency Response Interoperability Center
identified a set of "Applications Important to Public Safety" for
the 700 MHz National Public Safety Broadband Network (Ref. (1)).
Specifically1:
• Emergency Function
• Global Positioning Information
• CMAS-Public Warning
• Incident Management Tools
• Welcome Page
• Internet Access
• Virtual Private Networking
• Text Messaging
• Video
• File Transfer
• Telemetry
• Push-to-Talk Voice
The standards described herein provide standardized protocols
for a subset of the recommended applications listed above. Often,
the TIA documents provide specific operating profiles for existing
protocols codified by TIA or other standards development
organizations (SDOs) in order to leverage existing standards to the
greatest possible degree consistent with satisfying the needs of
the public safety community and other users of wireless broadband
systems.
The TIA standards do not define applications, but rather define
protocols that can be used by applications to meet the needs of
public safety and others. Generally, these standards specify the
upper layers (5-7 of the OSI model) and identify the transport
layer (layer 4) to be used for the protocol.
To facilitate development of a diverse set of applications by a
multiplicity of vendors that are nevertheless interoperable, this
suite of TIA standards defines protocols for the various required
services. Furthermore, because the fusion of information from
various content services will be an important part of public safety
applications, TIA will standardize an underlying grammar and
semantics for commonly used information elements. Application
protocols that share such information elements, will greatly
simplify the development of sophisticated applications that span
multiple services. Figure 1 illustrates this concept. Here a public
safety user accesses a variety of content services (i.e.
application protocols) that all share data representations for the
"context" of the service. This "metadata" can include location
information (e.g. where a particular video was shot), security data
(e.g. a series of digital signatures to prove chain of custody),
incident tags, and a variety of other common data.
This document is organized as follows:
Section 2 contains a list of abbreviations used in this
document.
Section 3 contains a list of references.
Section 4 describes an architectural model for the standards,
and
Section 5 summarizes the structure and nomenclature of the
series of standards documents.
