Police digital trunking communication system - General
technical specifications
1 Scope
This Standard specifies the technical characteristics, system composition and functional
requirements, operating frequency band, address and identification code, network
management, basic performance indicators of channel equipment, AC power supply
system, information security and confidentiality, environment and electromagnetic
compatibility, reliability and other general requirements of the police digital trunking
(PDT) communication system.
This Standard applies to the overall planning, network design, equipment development,
production, engineering construction and acceptance of the police digital trunking (PDT)
communication system.

5.2 Functional requirements
5.2.1 Functional definition
5.2.1.1 Registration
Registration is the process of a mobile station initiating a network access request and
confirming it to the trunking system. Authentication may be required during registration.
5.2.1.2 Deregistration
Deregistration is the process in which the mobile station sends a notification to the
trunking system to exit the system.
5.2.1.3 Authentication
The process of verifying the legitimacy of the identities of the parties involved in a
communication.
5.2.1.4 Roaming
In a system consisting of multiple base stations connected to the Internet, a mobile
station registers with a base station other than its home base station and continues to
use the services provided by the system.
5.2.1.5 Voice private call
A voice private call is a point-to-point two-way voice call established between a mobile
station and other user terminals. The participants of a call are only the caller and the
called party. There are two types of voice private calls between mobile stations:
FOACSU and OACSU.
5.2.1.6 Voice group call
A voice group call is a point-to-multipoint voice call initiated by a mobile station or
dispatch station and involving multiple mobile stations.
5.2.1.7 Group call late entry
After a group call is established and before it ends, the control channel periodically
broadcasts the establishment information of the group call to ensure that mobile stations
that have just been turned on, roamed to this base station from other base stations, or
released from other talk groups can participate in the group call that has not yet ended.
5.2.1.8 Group call merge
