Public Safety

Nokia public safety IP/MPLS network solution

With the Nokia public safety IP/MPLS network solution, public safety agencies gain an IP/MPLS network that has all the architecture attributes necessary. Solution highlights are:
• Scalable and flexible VPN services for TDM, Ethernet and IP
• Installation flexibility, which includes DIN mounting in small enclosures and
outdoor mounting on a wall, pole or stand without cabinet
• Integration with versatile packet microwave
• Built-in CWDM networking
• Graceful transmission medium migration from microwave and optics
• Synchronization based on Bell Labs technology
• End-to-end multi-domain IP management, including MPLS, microwave,
and optics

Solution components
The Nokia converged IP/MPLS network leverages multiple state-of-the-art technologies. The network extends IP/MPLS capabilities from the core to access and can include the following main components:
• Nokia 7750 Service Router (SR)
• Nokia 7705 Service Aggregation Router (SAR)
• Nokia 7450 Ethernet Service Switch (ESS)
• Nokia 7210 Service Access Switch (SAS)
• Nokia 9500 Microwave Packet Radio (MPR), providing a packet microwave link to connect MPLS nodes
• Nokia 1830 Photonic Service Switch (PSS), the optical layer underlying the IP/MPLS network
• Nokia 5620 Service Aware Manager (SAM) for service and network management

Blueprint backhaul network architecture
The Nokia IP/MPLS network solution helps public safety agencies to deploy converged networks for all applications while preserving QoS and reliability. This mission-critical design is ideal for public safety because it is capable of coping with LMR traffic now and scaling up for LTE traffic in the future. With strong solution components, network operators can design a network with a flexible architecture according to their unique set of requirements. Figure 8 shows a blueprint of an Nokia converged IP/MPLS communications network with microwave and optical integration for public safety. Packet microwave and optical assets are deployed to optimize connectivity and bandwidth. Pseudowires, VPLS and IP VPNs provide network virtualization for different applications.Public Safety Network MPLS

Integrated IP/MPLS and microwave domains
In a traditional architecture, IP/MPLS is overlaid over microwave transmission across two platforms. In the Nokia IP/MPLS network solution, the 9500 MPR is fully integrated with the 7705 SAR as a single, seamless, managed platform that converges the IP and microwave domains. Integration provides many benefits when microwave media are widely deployed:
• Elimination of multiple network managers
• Convergence of multiple indoor units (IDUs) and IP/MPLS router into one platform
• Rapid detection of microwave link degradation, including high bit error rate condition
• Reduced equipment space, sparing requirements, power consumption and cooling needs
• Streamlined installation and operations management

Conclusion
Public safety agencies are migrating their backhaul networks from TDM to packet for the efficient support of mission-critical LMR/TETRA applications and the eventual adoption of LTE mobile broadband. Agencies should ensure that their transformation to converged communications includes an IP/MPLS network because only IP/MPLS can provide the capability and reliability that is mandated by mission-critical services. The Nokia IP/MPLS network solution can help public safety agencies to extend and enhance their networks to support new IP-based applications while continuing to support TDM. These new technologies enable agencies to optimize their network flexibility and management and reduce CAPEX/OPEX without compromising safety, security or reliability. A service-aware IP/MPLS network enables the support of converged voice, data and video applications that can be managed using configurable QoS levels. The Nokia IP/MPLS network provides public safety agencies with:
• Reliable mission-critical services with high network availability
• Infrastructure sharing with VPNs
• Deterministic QoS for high-priority real-time applications
• Support for current and future mission-critical services
• Flexible time and frequency synchronization options
• Opportunities for reduced OPEX and CAPEX
• Preparation for eventual LTE adoption
• Strong security protection
