Emergency service architectures: Co-existence or Enemies?

From the current standardization activities it is possible to observe that different architectural spirits guide the protocol solution work. What are the currently discussed architectural choices? Will the future emergency service architecture work in all circumstances? What are the challenges and what are potential ways forward?

Unauthenticated network access : A deployable concept?

When emergency service requirements from the existing mobile phone system are directly translated to the VoIP based environment then SIM-less emergency calls are translated into a requirement for unauthenticated access to IP-based networks in case of emergency situations. Several organizations, e.g., IEEE and 3GPP, have already started to compile solutions to address a potential regulator requirement. What experience has been made during the design? What are the challenges and the potential impact for deployed and future networks? What are the regulatory requirements?

Location Configuration Protocols : How many more do we need?

End host and network manufacturers face a serious challenge: What protocols to deliver location information to end hosts and to network elements, such as SIP proxies or SIP servers, should be implemented? The list of potentially useful protocols is long: Location extensions to DHCP, link layer extensions, LLDP-MED, SUPL, HELD, etc. Do we need all protocols? Are some protocols more suitable for certain deployments than others? What guidance can be given to manufacturers and to network operators?

Location formats: Possibility for Convergence?

In addition to different location configuration protocols that are used to send location information between different nodes it can also be observed that different location information itself are being standardized. Some location configuration protocols are able to express only certain formats while in other areas the lack of coordination has lead to different location representations. Additionally, different location formats seem to be tailored to certain location determination techniques and hence to different environments. What is the current status and is there a chance for convergence?

Quality of Service & Emergency Services: Does it make sense?

Emergency calls are special calls that should not get impacted by the actions taken by other users (e.g., p2p file sharing download). To address admission control and priority treatment Quality of Service techniques have been proposed. Furthermore, requirements for authority-to-authority communication have been put into the game. QoS mechanisms add some degree of complexity to IP-based networks. What are the regulatory requirements? Is experience with QoS mechanisms available? Where are we with the standardization activities?

Security: Is the next generation emergency service infrastructure less secure?

The emergency service infrastructure for the Internet is different to the PSTN where every network has to be application aware and to understand the concept of an emergency call. With the Internet VoIP providers might be everywhere and calls might traverse a number of networks that do not understand the concept of a call. Various threats targeted at the emergency services infrastructure have been discussed that could be exploited. What are the security challenges? Are solutions available to tackle these threats?

Policy Implications on Complexity of Standards and Systems

With regulations surrounding emergency services signaling, what are the implications for adding complexity to the standards and systems needed to deliver a call for help to PSAPs and first responders? With added complexity, what are the risks of failing in the primary mission of emergency services calling. This panel discussion is an overview of the increase in complexity on standards and systems to meet anticipated regulations.
