1 Ensuring Public Safety Operating and managing TETRA networks

2 In the public safety field, mere seconds can mean the difference between life and death. To respond rapidly and deploy essential personnel, public safety organizations rely on their TETRA communications networks. Today, public safety agencies are under growing pressure to enhance network performance and reliability while holding down costs. Alcatel Lucent s Operations Support Systems solutions enable them to do just that, saving lives and reducing operational costs. Mission-critical communications for public safety Around the world, public safety organizations rely heavily on telecommunications networks to ensure mission-critical operations. Police forces, fire departments, emergency medical services, government authorities and others often operate Terrestrial Trunked Radio (TETRA) networks for vital communications. Public safety networks are frequently shared by several disciplines the police, firemen, ambulance services, etc. and combine multiple radio networks, including TETRA networks, paging systems, etc. These nodes are interconnected by a transmission network, which can include microwave, optics and IP-based transport. In this complex environment, public safety organizations need robust Operations Support Systems (OSS) to manage the infrastructure, enhancing network reliability and performance. They also need flexible Business Support Systems (BSS) to bill the various users, if required. An advanced OSS/BSS also enables public safety organization to hold down costs, a crucial consideration in a time of sharply reduced budgets in the public sector as result of the recent global recession. Alcatel-Lucent has a strong background as the trusted partner of public safety organizations to design and deploy, operate and maintain the optimal OSS solution, improving network reliability and performance while reining in costs. 2 Ensuring Public Safety

3 Role of the OSS/BSS OSS/BSS solutions are composed of an array of functions, including responsibility for fault, configuration, accounting, performance, provisioning, billing and security. Advanced Operations Support Systems provide end-to-end network service and process support, enabling system stakeholders to enhance system performance and reduce the total cost of ownership.

4 The public safety challenge For public safety organizations, the paramount challenge is to ensure their readiness to act, any time, anywhere. Meeting this challenge depends heavily on emergency communications, which are vital to mission-critical operations. In fact, internal police surveys show that police officers rely more on their portable handhelds than on their pistols! This places a heavy burden on the communications network, which must provide high systems availability, particularly in times of crisis. ENHANCING NET WORK PERFORMANCE TETRA networks are difficult to manage and operate, as they are usually linked to a complex infrastructure with multiple vendors, technologies and domains. This environment will become even more complicated with the integration of information technology (IT) applications and data requirements. The future addition of wireless broadband and new video and data services will create even greater complexity. To manage and operate the network efficiently, an OSS solution must integrate all operated systems, services and applications. The OSS then can improve network performance and reliability by delivering end-to-end service and process support, and by optimizing work processes. LOWERING THE COST OF OWNERSHIP Public safety organizations face serious, ongoing constraints in public spending. In this environment, cost-reduction efforts are essential. Advanced OSS solutions have a major impact, reducing operational expenditures (OPEX) by streamlining work processes through end-to-end service and process support. Mission-critical networks are generally operated over extended periods of time often 10 to 25 years. Any savings achieved in annual OPEX can therefore result in significant long-term savings for the police force or even the central government. By reducing the network s OPEX, OSS solutions can reduce its cost of ownership. DEVELOPING THE SERVICE ORIENTATION To incorporate a large and increasing number of new services, it is essential to develop the service orientation of the network. Service-oriented architectures, which mirror real-world operational activities, are highly adaptable to change. Currently, many TETRA networks remain organized in silo form, in which various network operations and systems address separate silos, or applications. The various components must be consolidated into a single OSS/BSS system, through a transition that implements best practices and enables the of new and legacy services. ADDING WIRELESS BROADBAND TETRA networks are narrowband networks designed to support voice services. Increasingly, public safety organizations are facing pressure to provide critical video and data services, to enhance capabilities in the field. This will mean adding a broadband overlay to the TETRA network. The introduction of broadband will allow the mobile terminal to be used as a multimedia device, providing user applications such as patient hospitalization, location tracking, car crash recovery services, police criminal register checking, video and picture dispatch, and biometric data transfer. Here again, a robust OSS is essential for successfully integrating the broadband overlay and end-user services. 4 Ensuring Public Safety

5 The Alcatel-Lucent solution Working as the trusted partner of your public safety organization, Alcatel-Lucent designs, integrates, deploys, operates and maintains a powerful OSS solution customized for your particular environment. The solution is designed to integrate all systems, services and applications associated with your TETRA network. This is particularly crucial for network infrastructures with multiple vendors, technologies and domains. Called an umbrella OSS, this comprehensive solution enhances performance by delivering end-to-end network service and process support, optimizing work processes. Our methodology Alcatel-Lucent s OSS solutions implement a middlewarebased service-oriented architecture (SOA). The introduction of SOA principles and governance enables us to design the appropriate OSS and determine the most effective transitioning strategy. In concrete terms, this approach provides a top-down view, enabling us to analyze current processes, verify that the processes fit organizational needs, and ensure that the technology precisely aligns with operational process needs. Alcatel-Lucent can help you with developing your service-oriented architecture. Our approach is governed by adherence to Alcatel-Lucent best practices and to industry standards, including the Information Technology Infrastructure Library (ITIL) and Enhanced Telecommunications Operations Map (etom).

6 A best-of-breed solution Alcatel-Lucent supports a best-of-breed umbrella OSS solution for public safety that enables customers to operate and maintain a nationwide mission-critical radio system in the most effective and efficient way. We build our OSS solutions from commercial off-the-shelf (COTS) products, customizing them for the particular TETRA network and then integrating them end-to-end. The OSS solutions are designed to handle the full range of operational processes, as shown in the diagram below. To integrate components for different vendors and technologies, Alcatel-Lucent has designed a series of pre-integrated adaptors, called tech-packs, which reduce overall integration cost and risk for you.

8 Reducing operational expenses Alcatel-Lucent s OSS solution reduces OPEX by optimizing work processes, making them more efficient end-to-end. The OSS hides the complexity of multiple element systems, providing automated operations and automated alarm correlation. This enables a more efficient use of human resources in managing the network 24/7. In a typical example, Alcatel-Lucent s OSS solution enabled UMS, the Netherlands police organization, to automate the handling of network alarms, reducing the number of alarms and identifying the cause of breakdowns. There was a corresponding reduction in the number of NOCs required, significantly lowering the network s total cost of ownership. It also generates significant cost savings in the Network Operations Centers (NOCs), as: g Fewer regional NOCs are needed g Fewer skilled employees are required in each NOC Figure 3.
