TETRA Dla Polski
A Mikromakro Institute Report TETRA for Poland 8 July 2011 ORGANISATIONAL & BUS INESS MODELS ISBN 978-83-62824-01-4 TETRA for Poland Page 1 TETRA for Poland ORGANISATIONAL & BUSINESS MODELS The deployment and implementation of a single nationwide communications system for public protection and disaster relief services is a complex challenge for any country. Synergies in the technical organisation of communications systems must be created for a number of different services, governed by different regulations and financed from different sources, which requires adaptation to their specific needs. One cannot discard the experience gained from their earlier operations, but on the other hand, some old ways, like the physical ownership and control of infrastructure need to be changed, because it is now better to share infrastructure with others. Securing stable financing for a major project can be quite a challenge, as it will compete with other important public policy objectives financed from the national budget. Even when governed by uncompromising security or national defence requirements, public telecommunications projects are increasingly often planned as long-term cooperation with private partners. The telecom sector has been commercialised over the last decade or so, and learned the ways of the market economy. Even if not designed to compete with market players, state-operated projects must take account of the market environment or else they will be unable to cope with their operating costs or secure finance for development. When taking on new challenges in the area of telecommunications, the public sector may take advantage of the knowledge of the private sector in the fields of technology, infrastructure roll-out, management of telecommunications operators' costs or application of sophisticated financial instruments. -

Empowering Smart Public Safety with Pervasive Broadband Networks
White Paper Empowering Smart Public Safety with Pervasive Broadband Networks Sponsored by: Huawei Baogui Ding Carrie MacGillivray Milly Xiang May 2014 IDC OPINION Cities all over the world share a myriad of common threats and challenges which, coupled with increasing urbanization, will continue to pose ongoing issues for years to come. Governments all over the globe are working on Smart City initiatives to provide more inclusive, secure, efficient, and effective services to citizens and thus improve the livability and sustainability of the wider city community. A "Smart City" is an ecosystem of smart initiatives including transport, healthcare, education, energy, water, building, public safety, and citizen services. At the heart of any Smart City is public safety which can be achieved by more efficiently utilizing city infrastructure, human resources, and massive public transportation to provide faster and more responsive emergency and public safety services. As an integral part of a Secured Smart City, Smart Public Safety is drawing increasing attention and investment globally. Smart Public Safety is characterized by using information and communications technology (ICT) to predict, prevent, and reduce crime; address new and emerging threats; improve emergency/disaster planning and response; reduce the cost of operations; and allocate resources more effectively. It is important for public safety organizations to recognize that a robust, interoperable communications system should provide not only reliable data but assist in organizing and analyzing the data in a meaningful way so that officials can make real-time decisions. Currently, most public safety communication systems are being deployed, or have been deployed, in one or several domains, but many still operate in silos. -
Poc Service Solutions for Public Safety Communications Over LTE Networks
Delay analysis of PoC service solutions for Public Safety communications over LTE networks DELAY ANALYSIS OF PUSH -TO -TALK OVER CELLULAR (P OC) SERVICE SOLUTIONS FOR PUBLIC SAFETY COMMUNICATIONS OVER LTE NETWORKS Author: Chengsui Lu Date: 27 August, 2012 Abstract – In this master thesis, the concept of public safety communication solutions over modern commercial cellular systems is presented, and the delay analysis for Puch-to-Talk over Cellular (PoC) service is provided especially for the LTE and IMS networks. Firstly, the motivations and requirements of public safety communications using commercial cellular technology are studied and introduced. Secondly, the 3GPP IMS-based public safety communication network architecture and the PoC service are described in details. Thirdly, we make a survey of the PoC delay targets for modern emergency communication networks. Finally, the call set-up delay and end to end delay calculations are done by dividing into latency components of each network entities. Our analysis shows that typical call set-up time and end to end delay are within 275 milliseconds and 250 milliseconds respectively, and the mainstream LTE cellular technology can be designed to satisfy the stringent time constraints for public safety purpose, making LTE a promising option for public safety communications. Key words: Public Safety communication networks; delay analysis; LTE; call setup time; end to end latency; IMS. 1/48 Delay analysis of PoC service solutions for Public Safety communications over LTE networks TABLE OF ACRONYMS -
