Building a Public Security System with GoTa

Overview
Governments in most countries use public mobile networks to communicate. Public mobile network has many weaknesses: no guarantee of security and privacy, lack of efficient and centralized response system, incapability to meet the emergency communication requirements, no group call function, and high communication expenses. Therefore, there is an urgent need to establish a public security system (PSS) for government departments.

The PSS can improve the government image and work efficiency. For a modern service-oriented government, discretionary services provided by individual departments can no longer meet the increasingly higher social requirements. Its capabilities to provide integrated services are an important index measuring the management level of a local government. The trend of government service is towards integrated and unified external service offerings by effectively coordinating various resources of government departments.


The PSS supports emergency response command and dispatch. Emergency events such as infectious disease, flood, earthquake have a great social impact and involve lots of people. It requires coordination of response work, unified leadership and fast actions. The PSS should be built to ensure that government and other forces, when handling emergency, can quickly, timely and correctly collect information, and that they can effectively communicate in various ways. The PSS has gradually become one of the major integrated city management systems to be developed in many countries.

ZTE's Global opening Trunking architecture (GoTa) system can be customized for the PSS to meet public security authorities on dispatch and command system applications.

Service Applications of PSS
The GoTa system provides rich service functions. In addition to the basic group calls, private calls and broadcast calls, GoTa PSS offers professional services including emergency call, dynamic regrouping, direct mode operation and dispatch console. The system also provides high-speed wireless data transmission, location positioning, as well as the ordinary voice functions of the public mobile network. Meanwhile, to meet the needs of users, a variety of GoTa terminals are provided, including encryption-capable terminals, explosion-proof terminals, and GPS GoTa vehicle-mounted stations.

The PSS can be used by government department staff at different levels, and is applicable for handling their routine work and emergencies. The following are examples to illustrate the applications of GoTa PSS:

Routine work of security and police departments
To enhance communications and improve work efficiency, security and police departments can apply the GoTa PSS to their daily work such as stopping and detecting crimes; managing transport, fire control, dangerous goods; and fighting terrorism.

The supporting services provided by GoTa PSS include PTT services (group and private calls), ordinary telephone services, SMS, location-based service, mobile video monitoring, and data transmission. GoTa PSS's end-to-end encryption function meets the requirements for confidential communication. Its direct operation mode enables secure communication between two terminals, and its positioning function can be used to track vehicles and people.

Emergency response to plant explosion or fire
For such severe incidents, there will be command headquarters and frontline command center to plan and execute coalition operations. The fire brigades are responsible for frontline fire fighting and rescuing while the police is in charge of guarding the fire site and maintaining the public and traffic order in nearby areas, and the medical treatment department handles emergency rescue, transfers of the injured patients, and making rescue treatment schemes.

Radio dispatch services include:
Group management
The commanding centers quickly group users via the dispatch console according to the alarms and the explosion pre-scheme, and regroup them according to the action schemes.

Group sending of short message
The commanding centers send group messages to inform all related people about the fire and the alarms.

Floor taken
A high priority user can take the floor of a low priority user so that emergency calls can proceed despite the system congestions; thus, the system can timely send out the most urgent and important information to guarantee fast response to emergencies.

Dynamic regrouping
The site commanders can dynamically regroup the police and fire staff, and other firemen for unified dispatch according to the actual situation of the explosion site.

Positioning
The positions of rescue workers and vehicles can be tracked.

Video monitoring
The command vehicles for coalition emergency response can use video cameras to wirelessly transmit pictures of the explosion site to the command centers so they can monitor the explosion site in real time.

Broadcast call
The commanding centers can send out broadcast calls to inform all users of the explosion site situations via the dispatch consoles.

Features of GoTa PSS
GoTa PSS offers all the applications for government departments. It has the following features:

  • Feature-rich service offerings: GoTa provides a whole set of wireless mobile services, including PTT, voice and broadband data services, to meet the wireless communication requirements of all government departments.
  • System security and privacy: Based on the advanced and mature CDMA technologies, the security of GoTa, which is further enhanced by terminal and system access authentication, is higher than other trunking systems. Meanwhile, GoTa can provide users with customized end-to-end encryption schemes, ensuring service application security for government departments.
  • Fast call connection and large capacity: The system offers fast call connection; and provide trunking services when some places have a large traffic load, or other public networks are unavailable.
  • Wireless broadband data service capability: GoTa, based on the 3G platform, offers the largest bandwidth for wireless data delivery among all existing trunking systems, providing government users with wireless data services such as high bandwidth wireless Internet access and image transmission.
  •  Low network construction cost: With open standards, complete industry chain, and high price-to-performance ratio of terminals and system, GoTa provides professional end-to-end trunking network solutions at reasonable prices.
  • Field-proven commercial deployments: To date, ZTE has commercially deployed its GoTa products in more than 20 countries such as China, Russia, Malaysia, Norway, Sri Lanka, Mongolia, Ghana, Benin, Liberia, Morocco and Libya.
  • Professional after-sales service team: ZTE has set up customer service centers in more than 100 countries in the world. Its local professional engineering teams provide users with 24/7 services to guarantee the safe, reliable operations of the system.

Conclusion
The GoTa PSS solution meets the dispatch requirements of the government and its subordinate departments in handling their routine work and emergencies.

The GoTa system, when applied to the public security sector, plays an important role in the operation of a government. Its capabilities are represented in the following aspects. Firstly, it improves communication within government departments. The trunking network facilitates smooth communication between the government and its subordinate departments, such as the public security bureau, immigration bureau, fire control department and customs. Secondly, it guarantees secure communication between government departments. Through the CDMA-based GoTa system, safe and independent communication services can be provided to the national defense department, national security department, and etc. Thirdly, it enhances emergency handling capabilities of the government. In case of emergencies, the domestic affairs department, national defense department and security department can uniformly dispatch police, fire control, customs and army via the GoTa system. Lastly, it meets the requirements for the wireless data transmission. In addition to voice trunking communications, government departments require data communication services. The GoTa system provides high-speed data transmission and caters to the wireless data transmission requirements of government departments. Therefore, as a professional trunking communications system, GoTa PSS brings great political and economic benefits to the governme
