This was given to me by a Telco guy in Canada. Talk about a great view of things to come. ESWG Consensus 12-month Report on Nomadic VoIP Technical and Operating Impediments to 9-1-1/E9-1-1 Service Delivery in Canada. PREPARE FOR 911 Executive Summary Emergency Services Working Group (ESWG) recommends on a consensus basis the Commission order the deployment of NENA Interim-2 (i2) compliant emergency services components, systems and upgrades to result in the operation within 18 months of enhanced 9-1-1 services for nomadic and fixed/non-native VoIP callers in Canada. ESWG also recommends that the Commission establish for planning purposes a milestone for the transition of all legacy analogue emergency services networks to IP-based emergency networks (so called next generation 9-1-1 networks) in Canada no sooner than 36 months after the deployment of i2. ESWG further recommends that the Commission order eight specific tasks with sequential milestones to assist with the orderly deployment of i2: 1. CISC should be ordered to deliver within 6 months a preferred PSAP funding model for VoIP E9-1-1 addressing regional/provincial variances and practices to produce a common national standard. 2. CISC should be ordered to deliver a comprehensive architecture for the implementation of VoIP E9-1-1 to deliver within 9 months specifying roles and responsibilities of all emergency services industry participants. 3. All 9-1-1 Service Providers ordered to provide MSAG for the purposes of LIS validity checking within 12 months subject to amended agreements. 4. All Broadband Internet Service Providers be ordered to provide LIS capability within 12 months at their own expense. 5. All 9-1-1 Service Providers be ordered to provide ALI/ANI capability consistent with NENA i2 implementation within 15 months at their own expense. 6. All local VoIP service providers be ordered to provide Call Servers and/or Proxy Gateway capability within 15 months at their own expense. 7. All 9-1-1 Service Providers be ordered to provide ESGW capability within 15 months at their own expense. 8. All VoIP 9-1-1 calls to be E9-1-1 delivered to the correct PSAP within 18 months (Full Production). ESWG also recommends the establishment of at least one pilot program / test region in Canada to evaluate and determine the best method and practices for transition from legacy to IP emergency services. Finally, ESWG requests Commission continue their practise of fostering advancement in emergency services by providing deadlines for the accomplishment of specific tasks through decisions and order the commencement of this deployment as quickly as is prudent. 1 Background 1.1 Decision CRTC 2005-21 Mandate This Emergency Services Working Group (ESWG) Consensus 12-month Report on Nomadic VoIP Technical and Operating Impediments to 9-1-1/E9-1-1 Service Delivery in Canada (the 12-month Report or the Report) is in response to the mandate given to CRTC Interconnection Steering Committee (CISC) by the Commission in Telecom Decision CRTC 2005-21 as follows: 72. The Commission remains of the view that, as these are technical and operational issues, the most effective approach to resolving them is through the CISC process, provided that CISC is guided by a fixed timeline. 73. Accordingly, the Commission requests CISC to submit to the Commission, within six months from the date of this Decision, a report identifying the technical and operational issues that impede 9-1-1/E9-1-1 service delivery when local VoIP service is offered on a fixed/non-native basis, and, within one year from the date of this Decision, a similar report with respect to local VoIP service offered on a nomadic basis. Each report should identify all viable solutions and recommend the preferred solution(s), with supporting rationale, and a proposed timeframe for implementation. [Emphasis added] 74. The Commission notes that certain parties suggested that CISC may benefit from participation in the NENA process in the United States. The Commission recognizes that the progress made by other national telecommunications regulators, with respect to the provisioning of emergency services with local VoIP services, may be of value to the Canadian industry and encourages CISC to monitor the reports and progress being made in other jurisdictions on this important issue. This 12-month Report follows up upon the issues identified in the ESWG 6-month Report on Fixed/Non-Native VoIP Technical and Operating Impediments to 9-1-1/E9-1-1 Service Delivery (the 6-month Report) as it was the conclusion of ESWG that the impediments in Canada were common between the Fixed/Non-native and Nomadic VoIP 9-1-1/E9-1-1 service delivery. In addition, this Report lays out the careful monitoring of the US-based National Emergency Number Association (NENA) process done by ESWG as well as the monitoring and contrast of the regulatory environment in the United States provided by the Federal Communications Commission (FCC) used to guide the development of the Report. 1.2 ESWG 6-month Report on Fixed/Non-Native VoIP Technical and Operating Impediments to 9-1-1/E9-1-1 Service Delivery On 3 November 2005, the ESWG filed Identification of Issues for Provision of 9-1-1/E9-1-1 Service to Fixed/Non-Native VoIP Customers, 27 October 2005 (ESRE0041) (the 6-Month Report). The ESWG submitted that the working group is currently exploring and evaluating alternative technologies to provide E9-1-1 solutions for nomadic VoIP services and that these technologies may also resolve the problems related to E9-1-1 service delivery to fixed/non-native VoIP customers. The ESWG recommended that the Commission review and consider the proposals to be put forward in the ESWG report on nomadic 9-1-1/E9-1-1 services before giving directions to the industry on what solutions should be implemented in order to ensure that 9-1-1/E9-1-1 services are provided in an effective and efficient manner to all VoIP local service subscribers. The 6-month report was approved by the Commission in Telecom Decision 2005-73, Consensus report on 9-1-1/E9-1-1 services provided to fixed/non-native VoIP subscribers on 20 December 2005. 1.3 NENA in the United States NENA's evolution of 9-1-1 systems and methods are described as: ? Immediate methods for Voice over Internet (i1) Route Voice over Internet calls to the correct PSAP outside the current E9-1-1 system network, optionally with caller ID. No mechanized ALI provided. ? Intermediate methods (pre i2) Solutions termed `pre i2' appear prior to the availability of full i2 interim solutions. These pre-i2 cases are subsets of the i2 characteristics and may not support device based location data capabilities. ? Migratory (Interim) solution for VoIP (i2) Route Voice over Internet and other types of VoIP calls into the current E9-1-1 systems and to the correct PSAP with correct ANI and ALI, accommodates both stationary and nomadic users, provides MSAG valid location information. Provides a method for nomadic user location either through an automated process or user input via a service prompted web based form or equivalent. Mobility (wireless VoIP) not supported beyond base station location identification. Provides a single industry adopted solution. ? Next Generation 9-1-1 (NG 9-1-1) (a.k.a. i3) Enable end to end IP based E9-1-1 design, supporting VoIP originated call delivery, and the transition of current wireline and wireless service providers to IP interface technology. Support IP mobility users, and all capabilities of i2. Utilize extended capabilities of IP to provide location and other information with the call, as well as other sub-sets of relevant data (Future Path Plan tier 3 and beyond). Provide a standard NG 9-1-1 solution which incorporates all requirements of E9-1-1, and the potential to easily support future IP-based communications devices. 1.4 Federal Communications Commission (FCC) Relevant Ruling (FCC05-116) On June 3, 2005 the FCC released the VoIP 911 Order adopting rules that require interconnected VoIP providers to provide their new and existing subscribers with 9-1-1 service no later than November 28, 2005. Specifically, as a condition of providing interconnected VoIP service, each interconnected VoIP provider must, in addition to satisfying the subscriber notification, acknowledgment, and labelling requirements: ? Transmit all 911 calls to the public safety answering point (PSAP), designated statewide default answering point, or appropriate local emergency authority that serves the caller's "Registered Location." Such transmissions must include the caller's Automatic Numbering Information (ANI) and Registered Location to the extent that the PSAP, designated statewide default answering point, or appropriate local emergency authority is capable of receiving and processing such information; ? Route all 911 calls through the use of ANI and, if necessary, pseudo-ANI, via the Wireline E911 Network, and make a caller's Registered Location available to the appropriate PSAP, designated statewide default answering point or appropriate local emergency authority from or through the appropriate Automatic Location Identification (ALI) database; ? Obtain from each of its existing and new customers, prior to the initiation of service, a Registered Location; and ? Provide all of their end users one or more methods of updating their Registered Location at will and in a timely manner. At least one method must allow end users to use only the same equipment (such as the Internet telephone) that they use to access their interconnected VoIP service. Additionally, the VoIP 911 Order required each interconnected VoIP provider to file with the Commission a Compliance Letter by November 28, 2005 detailing its compliance with the FCC 9-1-1 requirements or face suspension of service. The FCC also acknowledged the work being done by NENA in the provision of guidelines to assist companies in complying with the FCC orders. 1.5 Comparison to the Canadian situation There are two major differences to the Canadian situation to that present in the United States (US): first is the regulatory environment; and second is the degree of deployment of Wireless Phase II. The Commission in Telecom Decision 2005-28, Regulatory framework for voice communication services using Internet Protocol, provided specification on what constituted a VoIP service, VoIP service categories, the appropriate legislative framework, and application of the regulatory framework for local competition. The Commission dealt with the emergency service obligations for local VoIP service providers in Decision 2005-21 dealing with: the provision of E9-1-1 to fixed/native callers; the provision of basic 9-1-1 to all other callers on an interim basis; customer notification; status quo funding of the provincial 9-1-1 networks; and directing the production by CISC of the 6- and 12-month Reports. Contrary to the US situation where FCC05-116 ordered the immediate implementation by VoIP providers of the user information (ALI), use the routing (ANI or p-ANI) requirements and to provide a method for customers to update their registered location, the Canadian situation is to provide basic 9-1-1 on an interim basis where and when E9-1-1 cannot be provided. The US is essentially in the pre-i2 phase defined above with vendors working to develop and market i2 capable system components. As the US market represents a significantly larger market for vendors of emergency services systems it behoves Canadian VoIP 9-1-1 industry participants to use the guidelines of NENA to the greatest degree possible as vendors will first produce systems for US deployment of i2 before addressing any specific Canadian market requirements. It should be noted that the guideline for NG9-1-1 has not been published by NENA although work is progressing with vendors developing NG9-1-1 compliant system designs as part of the NENA Future Path Program. The second difference between the Canadian and US situation is the greater breadth of deployment of Wireless Phase II in the US. In Canada, Wireless Phase I, which allows call takers to receive the caller's wireless phone number for callback, is deployed in all provinces except Saskatchewan, and, while a Wireless Phase II pilot is being conducted by Bell Canada, no Wireless Phase II systems are in production. In the US, Wireless Phase II, which allows call takers to receive both the caller's wireless phone number and their location information, nearly 80 percent of public safety answering points (PSAPs) are capable of receiving Phase I location information and 57 percent have implemented Wireless Phase II for at least one wireless carrier . As NENA i2 is essentially an expansion of the capabilities and concepts of Wireless Phase II, the adoption of i2 is inextricably linked to the deployment of Wireless Phase II. This linkage between i2 and Wireless Phase II is beneficial as vendors that have developed Wireless Phase II systems are more readily able to develop and market i2 systems. 1.6 NTWG Review of IP-to-IP Tandem Enablement Proposals On 19 July 2005 ESWG received from the Network Working Group (NTWG) the evaluation of IP-to-IP Tandem Enablement proposals submitted for review. The NTWG review did not rank one proposal over the other. The NTWG review concluded that it was premature to evaluate connection of the local VoIP Service Providers to the existing 9-1-1 Tandem Service Providers' equipment without resolving what information would be passed, the specific protocol, and routing of information once received. 1.7 Description of Major Issues PSAP Funding (TIF 42) PSAP funding emerged as a major issue as it brought into focus the variation in funding that PSAPs receive and the limitations of that funding to address new system and process requirements. VoIP Caller Location Identification (TIF 45) Identification of the location of a VoIP 9-1-1 caller is crucial to determining first which PSAP is appropriate for them to be routed to and second in determining where to dispatch the emergency resources required. VoIP Caller Routing to PSAP (TIF 46) The technical routing of the VoIP 9-1-1 call to the PSAP introduces new terminal devices, network elements, and technologies to the delivery of a call to the appropriate PSAP. VoIP Caller Information to PSAP (TIF 47) VoIP 9-1-1 calling has the ability to broaden the amount and type of caller information to the PSAP. This TIF deals with what information is currently received that would be absent and attempts to identify if a lowest common information set recognizing the regional differences in PSAP equipment exists. 1.8 Methodology Issues Matrix An issues matrix was used as a working document to initiate, organize, and capture discussion within ESWG regarding the 12-month Report. Issues were suggested during the early plenary sessions of ESWG regarding the 12-month Report and were amended and appended subsequently as needed. The matrix discussion was used to clarify the issues, develop alternatives for addressing the issues, and then evaluate these alternatives with regard to effectiveness and feasibility. The matrix issues were primarily technical in nature and included alternatives that were beyond i2 and NG 9-1-1 capturing the challenges of Canadian implementation of E9-1-1 for VoIP. The process of ranking alternatives regarding effectiveness and feasibility provided the basis of whether consensus developed around a particular alternative. In addition, the matrix consensus items were identified as progress within the separate major issue TIFs. The major conclusion of the matrix discussion was that NG 9-1-1 was not yet sufficiently defined to allow implementation of systems in the near term when compared to i2. 1.9 Progress on Major Issues PSAP Funding (TIF 42) Unlike wireline or wireless callers, VoIP caller locations are not directly associated with the PSAP in which they reside or require service in due to the nature of IP networking. The migration of a caller from wireline or wireless service can potentially result in a loss of the associated call answer levy or municipal tax based funding to the PSAP. NENA i2 implementation would allow enumeration of the VoIP subscribers through their location as captured in the ALI database serving the PSAP continuing funding to the correct PSAP. It is also noted that funding can differ within a PSAP serving multiple municipalities and that PSAP funding varies in form across Canada. VoIP 9-1-1 Caller Location Identification (TIF 45) As VoIP handsets and access devices become location aware the requirement for the IP network to provide their location is not diminished but rather serves as corroboration of the location provided by the device. NENA i2 provides the building blocks upon which this corroboration occurs and deploys the base functionality to locate devices that are not location aware attached to an IP network when a 9-1-1 call is placed. VoIP 9-1-1 Caller Routing to PSAP (TIF 46) NENA i2 provides a method of routing VoIP 9-1-1 calls to the appropriate PSAP using modified or upgraded existing infrastructure and databases while delivering no less information to the PSAP than what is currently delivered based on the PSAP capability. VoIP 9-1-1 Caller Information to PSAP (TIF 47) NENA i2 has the ability to provide the same caller information via the same facilities to the existing PSAP terminal equipment. Specific PSAP capabilities may operate differently or be unavailable due to the call being placed using a VoIP device and these limitations are not specific to any local VoIP service provider but to the nature of IP networking. 2 Identification and Analysis of All Viable Solutions 2.1 NENA i2 NENA i2 consists of the interaction of following major components and interactions: ? Location information servers are operated by broadband Internet service provider(s) and allow determination of location within their deployed IP networks. ? Soft Switches are operated by local VoIP service providers and act as the switching fabric for IP 9-1-1 calls. Soft switches interact with the underlying location information server to locate the origin of the VoIP 9-1-1 call and the resultant appropriate emergency services gateway for that location. ? Call Routers/Proxy Servers route the 9-1-1 call from the soft switch to the appropriate Emergency services gateway for the appropriate PSAP. ? An emergency services gateway converts the IP 9-1-1 call into a traditional SS7 call and forwards the 9-1-1 call to the selective routers. ? Selective routers dip into purpose built and maintained or substantially upgraded databases to determine the appropriate PSAP, and to retrieve ALI and street address information before delivering the 9-1-1 voice call with associated information to the PSAP via existing trunking. ? The ALI databases and street address databases interact with new voice positioning databases and the location information servers in real time to refresh the caller location information during and after the 9-1-1 call. NENA i2 essentially supercharges the existing wireline E9-1-1 network to be capable of handling VoIP 9-1-1 calls in an enhanced manner. NENA i2 provides no advancement of capabilities for the PSAPs but focuses on integrating the new VoIP call type into the existing infrastructure by holding the interface to the PSAP constant. No i2 components are currently deployed in a production environment in Canada. Some carriers have latent i2 capabilities to varying degrees in deployed emergency services system components but these have not been integrated into workable systems. Vendors are currently marketing i2 components and systems in North America and providing upgrades to existing installed emergency system components to make them i2 ready. ESWG considers i2 to be the near term viable solution for Canada's 9-1-1 requirements. 2.2 Next Generation 9-1-1 (NG 9-1-1) NG 9-1-1 shares the same initial components as i2: location information servers, soft switches, call servers/proxy servers but changes the function of the emergency services gateway from protocol conversion into network security. All other interaction within a NG9-1-1 system, including delivery of the 9-1-1 call to the PSAP is done using IP. The benefits of using IP include the advancement of capabilities within the PSAP and the integration of other emergency service organizations to allow coordinated response to natural disasters and terrorism. If i2 can be characterised as a supercharging of the existing E9-1-1 wireline network, NG9-1-1 is full scale replacement of the engine of an E9-1-1 network moving wireline, wireless and VoIP E9-1-1 calling from legacy analogue (SS7) signalling to digital (IP) signalling. This ability to handle IP-based 9-1-1 calls without conversion combined with the expansion of capabilities offered by NG 9-1-1 defines it as the logical successor to legacy 9-1-1 emergency service networks limited by analogue components, including i2 networks. The specification of components that make up a NG 9-1-1 emergency systems is not complete therefore no vendors are providing NG 9-1-1 components or systems at the current time. Some vendors are currently installing pilot systems in accordance with the NENA Future Path Plan to ensure that their development and resultant products meet the NG 9-1-1 guidelines when available. These pilot systems are also being evaluated by the emergency service providers to gain knowledge as to the risks, limitations, and costs of transitioning from legacy 9-1-1 infrastructure to next generation 9-1-1 infrastructure and how best to accomplish the transition. ESWG considers NG 9-1-1 the viable long term solution to Canada's 9-1-1 requirements. 3 Recommendation: A Canadian Implementation of NENA i2 3.1 Major Points As a consequence of the availability of i2 components currently it is the recommendation of ESWG to proceed with the deployment and operation of an i2 emergency services network in Canada within 18 months of a decision to do so being ordered by the Commission. The ESWG recognizes that NG 9-1-1 is the successor to i2 therefore the Canadian implementation of i2 shall be consistent with the eventual transition to NG 9-1-1. A milestone for planning proposes of the i2 to NG 9-1-1 transition is recommended by ESWG to be at least 36 months after the implementation of i2 to allow for the recovery of the costs of i2 components and upgrades. All carriers, local VoIP service providers, and broadband Internet service providers shall be responsible for their own costs of deploying i2 components, systems, and upgrades. As the ability of PSAPs to deal with i2, and eventual NG 9-1-1, VoIP call information varies, and in some cases is completely lacking, ESWG recommends that the funding of PSAPs be evaluated on a national basis to ensure that capital and operating budget constraints do not interfere with the i2 implementation and that PSAPs are preparing for NG 9-1-1. ESWG recommends that the components of an i2 system are implemented in a coordinated sequence to ensure the testing of operation and security of the resultant production environment while providing no competitive advantage to any industry participant. 3.2 Pilot Program / Test Region Given the NENA Future Path Plan towards Next Generation E9-1-1 it would be prudent to formally recognize and support the implementation of a hybrid NENA i2 and NG 9-1-1 solution or a pure NG 9-1-1 solution as a pilot program within a specified region of Canada. ESWG recommends that at least one such pilot program be supported provided that cooperation is received from the PSAP(s) within the pilot region. It is noted by ESWG that even if such a pilot program is converted into a production environment within the pilot region doing so does not inhibit or interfere with the deployment of i2 in all other regions of Canada as NG9-1-1 is backward compatible to i2 by design. 3.3 Implications of Recommendation on Interim Solutions No specific implications were determined resulting from the recommendation of an i2 implementation upon the interim solutions regarding VoIP 9-1-1 call handling currently in effect in Canada. 4 Proposed Timeline for Implementation 4.1 Major Milestones and Immediate Orders Requested 1. CISC should be ordered to deliver within 6 months a preferred PSAP funding model for VoIP E9-1-1 addressing regional/provincial variances and practices to produce a common national standard. 2. CISC should be ordered to deliver a comprehensive architecture for the implementation of VoIP E9-1-1 to deliver within 9 months specifying roles and responsibilities of all emergency services industry participants. 3. All 9-1-1 Service Providers ordered to provide MSAG for the purposes of LIS validity checking within 12 month, subject to amended agreements. 4. All Broadband Internet Service Providers be ordered to provide LIS capability within 12 months at their own expense. 5. All 9-1-1 Service Providers be ordered to provide ALI/ANI capability consistent with NENA i2 implementation within 15 months at their own expense. 6. All local VoIP service providers be ordered to provide Call Servers and/or Proxy Gateway capability within 15 months at their own expense. 7. All 9-1-1 Service Providers be ordered to provide ESGW capability within 15 months at their own expense. 8. All VoIP 9-1-1 calls to be E9-1-1 delivered to the correct PSAP within 18 months (Full Production). 4.2 Request for Commission Decision prior to proceeding As successful implementation of an i2 emergency services network in Canada involves the participation and coordination of companies and organizations not currently involved with the delivery of E9-1-1 calls currently (i.e., Broadband Internet service providers providing location information or services on their access or underlying IP networks) ESWG requests that the Commission make the complete set of orders above before requiring the industry participants to proceed. The 18 month implementation recommendation by ESWG is the minimum period required to allow participants to plan, budget, acquire and implement the various i2 components, systems and upgrades required. 5 Conclusion With the number of VoIP subscribers estimated to be over 1 million by the end of 2006 there is a pressing and urgent need to provide these subscribers with efficient and effective enhanced 9-1-1 service. Additionally, the inherent nature of VoIP, with easy nomadic capability and ease of becoming a fixed non-native caller in any region of Canada regardless of how remote, presents daily challenges to the dedicated members of the PSAPs and emergency response agencies to act expeditiously to save lives of VoIP 9-1-1 callers. ESWG concludes that it is crucial to act quickly to determine a course to deliver a practical and sustainable solution to VoIP 9-1-1 calls and to provide a path to the next generation of 9-1-1 emergency services for all Canadians. ESWG recommends the deployment of NENA's i2 compliant system in Canada on an 18-month timeline. ESWG also requests that the Commission continue their practise of fostering advancement in emergency services by providing deadlines for the accomplishment of specific tasks through decisions and order the commencement of this deployment as quickly as is prudent. In order to provide the next generation of 9-1-1 services in Canada that are being made possible by the wide adoption of IP the ESWG also recommends that the Commission establish a milestone for the transition to NG9-1-1 services no less than 36 months after the deployment of i2 emergency systems.
