ITU-T Y.2205

Abstract

This Recommendation specifies technical considerations that can optionally be applied within the Next Generation Network (NGN) to enable emergency telecommunications (ET). In addition, the Recommendation also outlines the underlying technical principles involved in supporting ET. It specifies requirements and capabilities for ET beyond the ones specified in [ITU-T Y.2201] in the context of NGN (as defined in [ITU-T Y.2001] and further outlined in [ITU-T Y.2011]). <br>Emergency telecommunications (including support of some aspects of early warning (see Figure 1)) include: <br>&#8226; individual-to-authority emergency telecommunications, e.g., calls to emergency service providers; <br>&#8226; authority-to-authority emergency telecommunications; <br>&#8226; authority-to-individual emergency telecommunications, e.g., community notification services. <br>Appendix I provides additional information for the above listed ET categories. <br>Some requirements and capabilities for early warning are also specified. Individual-to-authority emergency telecommunications capabilities are not addressed and are outside the scope of this Recommendation. <br>Some of the technical means described herein could also be used for individual-to-authority or individual-to-individual emergency telecommunications, however, these categories are not addressed in this Recommendation.
